A tool position detection device (3) is provided with: a photoelectric sensor (7) that is capable of detecting a timing of cutting off an optical path (L) by a wire (10b); a support frame (8) that supports the photoelectric sensor (7); and a rotary actuator (12) that rotates the support frame (8) by 90° forward and backward about the rotation axis (C1) orthogonal to the optical path (L). A deviation amount calculation unit (6a) calculates, on the basis of the movement velocity V of the wire (10b) and the difference Δt between the reference value t1 and an actual measurement value t2 of the timing of cutting off the optical path (L) by the wire (10b), the positional deviation amount ΔS of the wire (10b) = V×Δt.
A rotating body (2) of a rotary changer (1) comprises: an inner cylindrical body (7) having a hollow portion (7a); an outer cylindrical body (8) that accommodates the inner cylindrical body (7) vertically slidably; and a plurality of gripping members (9). A first cam inclined surface (9c) and a protruding portion (9d) are formed in each gripping member (9). The outer cylindrical body (8) is provided with: a second cam inclined surface (8g) for advancing each gripping member (9) by a sliding movement in contact with the first cam inclined surface (9c); and a third cam inclined surface (8k) for retracting each gripping member (9) by a sliding movement in contact with the protruding portion (9d). A rotating body (3) rotates and replaces a nozzle (11) gripped by an advancing movement of each gripping member (9).
A rotary grip (9) grips a nozzle (11) in a component replacement area (V2) in a forward rotation or in a reverse rotation about a central axis of the nozzle (11). A rotary storage (4) stores a plurality of nozzles (11) at predetermined intervals in a circumferential direction about an axis of rotation (C1) and moves each of the plurality of nozzles (11) to a component supply area (V1) by rotating about the axis of rotation (C1). A component transporter (7) transports each nozzle (11) from the component supply area (V1) to the component replacement area (V2). A clutch assembly (8) transmits rotation and blocks transmission of rotation between the rotary storage (4) and a drive motor (5).

A tip case (3) stores a plurality of contact tips (10) linearly aligned in a horizontal direction and each having a tip end facing downward. A reciprocator (5) reciprocates the tip case (3) in a direction in which the plurality of contact tips (10) are aligned to move the tip case (3) into or out of a tip supplying space (S2). A tip ejector (6) ejects a contact tip (10) of the plurality of contact tips (10) upward from the tip case (3) moved into the tip supplying space (2). A holder-rotator (4) screws the contact tip (10) ejected by the tip ejector (6) into a torch body (11) or detaches the contact tip (10) from the torch body (11).
The present invention includes a rotating grip body (9) that grips a nozzle (11) so as to be capable of forward and reverse rotation around the central axis thereof in a component replacement area (V2). A rotating storage body (4) is configured so as to be capable of storing a plurality of the nozzles (11) in a circumferential direction around a center of rotation (C1) and causes each of the nozzles (11) to move toward a component supply area (V1) by rotating operation around the center of rotation (C1). A component conveyance mechanism (7) conveys the nozzles (11) from the component supply area (V1) to the component replacement area (V2). The present invention comprises a clutch mechanism (8) that transmits or blocks rotation between the rotating storage body (4) and a drive motor (5).
In the present invention, a tip case (3) accommodates a plurality of contact tips (10) linearly in a horizontal direction and in an orientation in which distal ends of the contact tips (10) face downward. A back-and-forth driving mechanism (5) causes the tip case (3) to move back and forth in the direction in which the contact tips (10) are arranged in a row, causing the tip case (3) to advance into and retreat from a tip supply space (S2). A tip extraction mechanism (6) upwardly extracts the contact tips (10) from the tip case (3) in a state in which the tip case (3) has advanced into the tip supply space (S2). A grip rotation mechanism (4) helically links the contact tip (10) extracted by the tip extraction mechanism (6) to a torch body (11), or removes the contact tip (10) from the torch body (11).
A device is provided with a first die, a second die and a pressing machine. The second die is provided with a plastic processing hole where a core metal is disposed on a hole center line. On the inner peripheral surface of the plastic processing hole, three projecting portions are provided at regular intervals in the circumferential direction of the hole center line. By the approach of the first and second dies to each other, the core metal is inserted into a guide hole of a contact tip, and the projecting portions plastically deform the head end side of the contact tip by pressing it until it is in contact with the core metal.
A device (1) is provided with a first die (2), a second die (3), and a press machine (4). The second die (3) has a plastic processing hole (3a) in which a core metal (3f) is arranged on a hole center line (C1). The plastic processing hole (3a) has an inner circumferential surface on which three ridges (3b) are provided at regular intervals in the circumferential direction of the hole center line (C1). As the first and second dies (2), (3) are moved closer to each other, the core (3f) is inserted into the guide hole (10a) of the contact chip (10) and the ridges (3b) cause the tip-end side of the contact chip (10) to be pressed and plastically deformed until coming into contact with the core (3f).

A moving means (13) makes a rotational axis center (C2) of each driven side rotating body (8) align with a rotational axis center (C1) of a drive side rotating body (45). The drive side rotating body (45) has a mating surface (45b) extending along the direction of the axial center thereof. The driven side rotating body (8) has a mating receiving surface (8d) extending along the direction of the axial center of the drive side rotating body (45). With rotation of the drive side rotating body (45) in a state where the driven side rotating body (8), the rotational axis center (C2) of which is aligned with the rotational axis center (C1), is moved to the drive side rotating body (45) side, the mating surface (45b) engages the mating receiving surface (8d).
A moving mechanism brings the rotational axis of each driven rotator into alignment with the rotational axis of a drive rotator, which has an engaging face extending along its rotational axis. Each driven rotator has an engageable face extending along the rotational axis of the drive rotator. Rotating the drive rotator while moving the driven rotator, of which the rotational axis is aligned with the rotational axis, toward the drive rotator will bring the engaging face into engagement with the engageable face.

An interlocking member is arranged to rotate integrally with the rotator and be movable in a direction intersecting with the rotational axis. The interlocking member has an interlocking groove interlockable with an outer peripheral surface of a nozzle inserted into the hollow of the rotator. Rotating the rotator with the interlocking member interlocked with the nozzle makes the nozzle replaceable.

A coupling member (6) is provided so as to integratedly rotate with the rotating body (3), and is provided movably in a direction crossing the axial center (C3) of rotation. A coupling groove (60) in the coupling member (6) is coupled to the outer peripheral surface of a nozzle (11) inserted into a hollow part (30) of the rotating body (3). The nozzle (11) is replaced by the rotating body (3) rotating with the coupling member (6) being coupled to the nozzle (11).
