Abstract

[Problem] To provide a portable power tool that automatically gives a notification pertaining to the timing of replacement of a tip tool. [Solution] A portable power tool according to the present invention is a belt type grinding tool that performs grinding work by driving an endless grinding belt B. The belt type grinding tool calculates a cumulative drive time by summing the drive time of an air motor in a state in which the grinding work is being performed by the endless grinding belt, and compares the cumulative drive time with a replacement recommendation time stored in a memory (S112). Then, a notification signal is transmitted when the cumulative drive time becomes not less than the replacement recommendation time (S114). Further, when breakage of the endless grinding belt is detected (S116), a new replacement recommendation time is set (S118). When the new replacement recommendation time is less than the existing replacement recommendation time (S120), the replacement recommendation time is updated (S122).

Abstract

[Problem] To provide a belt replacement device that executes assistance so that a robot system can perform automatic replacement of an endless grinding belt of a belt-type grinding tool incorporated into the robot system. [Solution] A belt replacement device 10 comprises a mounted belt retaining section 62, belt support members 70-1, 70-2, and a button pressing member 82. When a drive pulley 4 and an idle pulley 6 of a belt-type grinding tool 1 are pressed against the mounted belt retaining section 62 so that the mounted belt retaining section 62 shifts to an adjacent position, the belt support members 70-1, 70-2 support an endless grinding belt B0 retained by the mounted belt retaining section 62, thereby restricting movement. Accordingly, the endless grinding belt B0 moves away from the mounted belt retaining section 62 so as to be positioned near the drive pulley 4 and the idle pulley 6. The button pressing member 82 presses a lock release button 9 to release retention of an tension bar 5, causing the endless grinding belt B0 to be mounted on the belt-type grinding tool 1.

Abstract

[Problem] To provide a pipe joint member with which an operator can more reliably recognize that fluid pressure is being applied to the pipe joint member when an attempt was made to connect a corresponding pipe joint member while fluid pressure was applied to the pipe joint member. [Solution] A female pipe joint member 10 is removably connected to a corresponding male pipe joint member 1. When the female pipe joint member 10 receives fluid pressure from the rear-end opening 14 with the male pipe joint member 1 in a disconnected state, a second slide member 26 is displaced to the forward position, and a first lock 78 is held in a displacement-preventing position by the second slide member 26. This prevents a first slide member 24 from being displaced from a forward position to a rearward position. If an attempt is made to insert the male pipe joint member 1 into an internal space 16 of the female pipe joint member 10, a front end surface 2 of the male pipe joint member 1 engages with the first slide member 24 and the male pipe joint member 1 cannot be inserted to a predetermined position where connection will be completed.

Abstract

A clutch mechanism includes a first clutch plate retaining circular columnar engagement members and a second clutch plate retaining spherical engagement members. In the second clutch plate, inner retaining holes and outer retaining holes positioned more radially outward than the inner retaining holes are formed. The outer retaining holes are larger in diameter than the inner retaining holes. On assembly of the clutch mechanism, engagement members are selected from small-diameter spherical engagement members corresponding to the small-diameter inner retaining holes and large-diameter spherical engagement members corresponding to the large-diameter inner retaining holes. The selected engagement members are disposed in the corresponding retaining holes, respectively. The maximum rotational torque is greater when the large-diameter spherical engagement members are selectively disposed than when the small-diameter spherical engagement members are selectively disposed.

Abstract

An electric motor-driven screwdriver includes a control circuit having a memory stored with setting data and a computing unit controlling the electric motor-driven screwdriver based on the setting data. The computing unit sets an execution order of work processes based on a pre-designated piece of order setting data, and sets, based on a next operation setting value, a next operation to be performed after completion of the final work process. The next operation setting value is selectable from among a setting value for stopping the operation of the electric motor-driven screwdriver, a setting value for repeating a series of work processes, and a setting value for shifting to a series of work processes in an execution order determined based on another piece of order setting data.

Abstract

Provided is a pipe joint configured so that it is possible to maintain sealing performance between pipe joint members even when the temperature becomes a high temperature or a low temperature and the sealing performance of an elastic seal member is reduced. The pipe joint (100) comprises a female pipe joint member (102) and a male pipe joint member (104) that are detachably connected to each other. The interval between a female pipe joint body (112) and a male pipe joint body (132) is sealed by an elastic seal member (126) when in the connected state. A first seal surface (136) is formed on the inner circumferential surface (112b) of the female pipe joint body (112) and a second seal surface (140) facing the first seal surface (136) is formed on the outer circumferential surface (132a) of the male pipe joint body (132). The female pipe joint body (112) is formed from a material having a larger thermal expansion coefficient than that of the male pipe joint body (132). When the female pipe joint body (112) and the male pipe joint body (132) are cooled to a temperature equal to or lower than a certain temperature, thermal shrinkage causes the first seal surface (136) and the second seal surface (140) to press against each other and engage in a sealed manner.

Abstract

A pipe coupling includes a male coupling member detachably connected to a female coupling member by a chuck member of the female coupling member. The chuck member is disposed radially outside of a female coupling body to extend forward beyond a front end opening. The chuck member is displaceable in a longitudinal direction and also radially displaceable between a locking position where a locking groove locks a locking projection and an unlocking position where the locking groove is displaced radially outward from the locking position to unlock the locking projection. When the chuck member is displaced rearward from a temporarily connecting position to a connecting position in a state where the locking groove has locked the locking projection in the temporarily connecting position, the chuck member draws the male coupling member into a female-side passage to connect the male coupling member to the female coupling member.

Abstract

A coupling member inhibits accidental pivoting of a lever for operating a movable member such as a chuck member or a valve. The coupling member has a chuck member mounted displaceably relative to a female coupling body between a temporarily connecting position (first position) and a connecting position (second position). The chuck member is operated by a lever that is pivotable relative to the female coupling body. When the lever is pivoted from a first pivoting position to a second pivoting position, the chuck member is displaced from the temporarily connecting position to the connecting position to connect an associated male coupling member. When the lever is in the second pivoting position, a lock member of the lever engages a lever holding member to inhibit the lever from pivoting toward the first pivoting position.

Abstract

[Problem] To provide an air tool configured in such a way that an operator can easily recognize a state in which a release valve is in a released position, and a switching valve is in a neutral position. [Solution] A belt-type grinding tool (100) is provided with: an air motor (112) capable of forward rotation and reverse rotation; an opening and closing valve (126) which opens and closes an air supply passage (144); and a switching valve (124) which switches the air supply passage (144). When the switching valve (124) is in a neutral position between a forward rotation position and a reverse rotation position, first and second branch air supply passages (154, 156) are caused to communicate with the air supply passage (144), and the first and second branch air supply passages (154, 156) are caused to communicate with an exhaust passage. Compressed air reaches the first and second branch air supply passages (154, 156) from the air supply passage (144), and either passes through the air motor (112) from first and second motor air supply ports of the air motor (112) and reaches the exhaust passage, or reaches the exhaust passage without passing through the air motor (112), and is exhausted to the outside. An exhaust sound is generated at this time together with the exhaust.

Abstract

Provided is a belt-type grinding tool in which a spring support member is prevented from pivoting in the direction in which compression of a spring is released due to an urging force received from the spring. This invention is provided with a spring support member (38) capable of pivoting between: a tension imparting position, at which a pressing support surface (46) presses an engaging part (44) of a spring seat (30), compresses and supports a spring (32) between the pressing support surface (46) and a pulley support bar (16), and applies tension to an endless grinding belt (20); and a tension release position at which the amount of compression of the spring (32) is reduced so that tension is reduced. The pressing support surface (46) of the spring support member (38) and the engaging part (44) of the spring seat (30) are shaped so that the line of action of a force received by the pressing support surface (46) from the engaging part (44) when the spring support member (38) is at the tension imparting position passes through the side of a pivot axis (R) in which a moment is produced that causes the spring support member (38) to pivot in the direction away from the tension release position.

Abstract

Provided is a screwing-member-fastening tool with which it is possible to more easily set the driving time until a switch is made from high-speed rotation to low-speed rotation. An electric screwdriver device in which a driver bit is rotationally driven for a high-speed driving time at a prescribed high rotation speed and then rotationally driven at a prescribed low rotation speed that is lower than the high rotation speed. A control unit: performs a driving control on an electric motor so that the driver bit is rotationally driven at a set rotation speed (S32); measures the fastening time required until the fastening of a screwing member engaged with the driver bit is detected by a Hall element (S34); calculates an initial setting time by multiplying, by the fastening time, a prescribed positive value less than one and a value obtained by dividing the set rotation speed by the high rotation speed (S36); and sets the initial setting time as the high-speed drive time (S40).

Abstract

[Problem] Provided is a filter device for removing liquid particles, capable of removing liquid particles in gas flow without increasing flow path resistance. [Solution] This filter device for removing liquid particles includes a fluid removal flow path (22) for removing liquid particles by passing through liquid particle-entraining gas, and a gas introduction path (24) that introduces the liquid particle-entraining gas in a particle removal flow path (22). At least part of the peripheral wall defining the particle removal flow path is made of a water absorbing material (32), and the gas introduction path (24) introduces the liquid particle-entraining gas so that the liquid particle-entraining gas collides against the wall surface of the particle removal flow path made of the water absorbing material. By being collided with the liquid particle-entraining gas, the water absorbing material adsorbs liquid particles that are entrained by the gas.
