Abstract

A grinding machine includes a grinding machine body and a grinding disc connected to the grinding machine body. The grinding machine body is provided with a pressure cavity at a position facing the grinding disc and a gas intake pipe corresponding to the pressure cavity. A pressure release gap in communication with the pressure cavity is formed between the grinding machine body and the grinding disc. The gas intake pipe induces a high-pressure gas into the pressure cavity, which receives an effect of the high-pressure gas to become a positive-pressure environment. The high-pressure gas is continually released via the pressure release gap to prohibit external dust from entering the pressure cavity. Thus, the grinding machine is capable of preventing dust from accumulating in the pressure cavity as well as effectively preventing moisture from entering the pressure cavity when the grinding machine is applied for wet grinding.

Abstract

A power-driving motor for power-driving bike is provided, of which the length is obviously larger than its width. A rotor of the power-driving motor is provided at the outside of the stator so as to make the distance from the rotor to the motor spindle increase; namely, a torque increases and then an arm increases, thereby, making the motor spindle supply a higher output torque to the connected driving unit when the rotor rotates. The motor, based on the length of a conventional power-driving motor, may supply a higher output torque to solve the defect of a conventional motor implemented with an inner rotor of which the output torque is insufficient.

Abstract

An electric hand tool is provided. The electric hand tool receives a shutdown signal issued by a shutdown element under control during an operation process of the electric hand tool, so as to request a driving module to stop providing a driving signal to a plurality of coils provided at the electric motor, and to conduct a brake loop connected to the coils and the driving module. Thus, a short circuit is formed between the coils and the driving module to cause the electric motor to temporarily enter a power generating state to generate a sensing current. The coils receive the sensing current to establish a first magnetic field. The first magnetic field interferes with a second magnetic field produced by a plurality of permanent magnets to form an interfering repulsive force that stops the rotor from rotating, thereby achieving an object of braking promptly.

Abstract

A machine tool with a heat conduction structure comprises a machine tool and a heat dissipation seat installed on the machine tool. The machine tool has a handle. The handle has an accommodation space accommodating a circuit board and having an opening at one end. The heat dissipation seat has a heat dissipation member arranged on the opening and a carrying member connected with the heat dissipation member and extended to the accommodation space.

Abstract

An electric power tool receives an input power from an electric power source and converts the input power to a driving power to drive an electric motor. The electric power tool further includes a manual control mechanism, a magnetic control element and a power modulation circuit. The manual control mechanism includes a trigger portion movable by depressing of a user and a magnetic element movable with the trigger portion. The magnetic control element outputs an output control signal in proportion to alterations of a magnetic field caused by movements of the magnetic element. The power modulation circuit gets the input power and modulates to the driving power controlled by the output control signal to drive the electric motor. Thus by depressing the trigger portion, output power of the electric motor can be controlled to provide precise control of rotational speed and torque alterations.

Abstract

A negative pressure dust collection structure aims to be used on a power tool which is coupled with an application tool operable in a working space surrounded by a dust collection hood. The dust collection hood includes at least one flow conduction vent communicating with an airflow duct through a negative pressure enhancing duct. The negative pressure enhancing duct has a negative pressure enhancing chamber communicating with the flow conduction vent. The negative pressure enhancing chamber is formed at a cross section shrunk gradually from the flow conduction vent towards the airflow duct to increase suction of the negative pressure enhancing duct to collect dust in the dust collection hood. Moreover, the negative pressure enhancing chamber has an opening edge mating the shape of the inner side of the wall of the dust collection hood to increase covering range of the airflow.

Abstract

A dust proof structure for a machine tool includes a flow guiding element located therein. The machine tool includes a housing chamber to hold a spindle and the flow guiding element. The housing chamber has an air intake section and an air discharge section communicating with the air intake section. The machine tool further has an air inlet communicating with the air intake section and an air outlet communicating with the air discharge section. The spindle is coupled with an action member outside the air outlet. When the spindle drives the action member to operate, the flow guiding element introduces external air through the air inlet to the air intake section, and directs the air to the air discharge section to be discharged towards the action member. Hence dust generated by the action member during operation of the machine tool does not enter the machine tool through the air outlet.

Abstract

A heat dissipation structure for sealed machine tools includes a motor rotor rotating to drive airflow to perform heat dissipation simultaneously. It includes a machine tool housing with a heat dissipation vent and a chamber inside, a stator in the chamber and a rotor located between the stator and the housing. The rotor and the housing wall form a swirling flow space between them. The rotor and the stator form an axial flow space between them. The swirling flow space and the axial flow space communicate through a radial airflow passage. The rotor has at least one flow directing portion. The rotor rotates relative to the stator. The stator generates thermal airflow which flows from the axial flow space through a radial airflow passage to the swirling flow space. The flow directing portion performs an exchange of cooling air and thermal airflow through the heat dissipation vent.

Abstract

A pneumatic turbine motor air chamber drives a pneumatic turbine to rotate through compressed air. The pneumatic turbine has a ring extended from inside thereof that has a plurality of barriers and forms a housing space to hold a speed regulator. The pneumatic turbine also has an air intake coupling hole leading to the housing space and at least one air discharge vent communicating with an air passage to discharge the compressed air. The ring is integrally formed with the pneumatic turbine to enhance operation steadiness of the pneumatic turbine.

Abstract

A tool holder structure includes a holder installed on a connecting portion of a machine for holding a tool, the holder has a connecting cone for connecting the connecting portion, and a latching portion with an external diameter larger than the connecting cone disposed at the bottom of the connecting cone. The invention installs a ring between the latching portion and a surface of the connecting portion for pressing and connecting the connecting portion to define a tight engagement, so that the holder can be connected to a machine by the connecting cone as well as the ring. The invention can greatly enhance the stability for operations and the precision of manufacturing dimensions, and the invention can be used extensively for various different machines and holders of existing specifications while providing stable operations of the machines and extending the life of the machines.
