A chip scattering prevention cover (1) is attached to a head portion (6b) of a rotary cutter (6). The cover (1) includes an annular portion (1a) configured to be detachably fitted over an outer peripheral edge of the head portion (6b), and a plate portion (1b) extending inwardly of the annular portion (1a) from an inner circumference portion of the annular portion (1a). The plate portion (1b) is configured to cover a region of a cutout gap (6e) of the rotary cutter (6) corresponding to the head portion (6b) with the annular portion (1a) being fitted over the head portion (6b). The annular portion (1a) and the plate portion (1b) are flush with a surface of the head portion (6b) when the annular portion (1a) is fitted over the head portion (6b).

In the present disclosure, a pair of removing members (5) are provided to be able to move toward and away from each other. Each of the removing members (5) includes a nail (5A, 5B) capable of being inserted into a gap (S1) between a large diameter portion (11a) and an electrode tip (12), and a protrusion (54) extending in a direction intersecting with a direction of insertion of the nail (5A, 5B) into the gap. The protrusions (54) of one and the other one of the removing members (5) are axially supported respectively by first and second support portions (81a, 81b) provided on one end of an arm member (8). The first support portion (81a) is in the shape of a groove that is shaped to be gradually closer to the other one of the removing members as progressing toward the other end of the arm member (8).

A rotation arm (3) has, at its one end, a pair of first slits (31b) configured to guide associated protrusions (2f) of the other one of removing members (2) such that the removing members (2) are separated from each other in the center axis direction (C1) by pressing both of nails (2d) downward with a large-diameter portion (11a) of a welding gun (11) to rotate the rotation arm (3). A body frame (4) has a second guide (13) configured to guide the rotation arm (3) such that when the rotation arm (3) rotates, a central portion of each removing member (2) between the associated protrusions (2f) moves along the center axis (11c).

Provided is a spot welding electrode housing apparatus having a reduced size such that an operation of mounting electrodes on a welding gun is less likely to affect a line takt time. Specifically, a rotation regulator 7 positioned adjacent to a rotating plate 2 in a direction of a rotation axis is configured to allow the rotating plate 2 to abut against an electrode 10 housed and held in a first recess 23 or a second recess 24 and thereby to regulate a rotation of the rotating plate 2 toward one direction around the rotation axis when the rotating plate 2 rotationally biased by a spiral spring 6 toward the one direction around the rotation axis is allowed to rotate toward the other direction around the rotation axis against a biasing force of the spiral spring 6.

Provided is a method for grinding electrode tips such that the method is capable of detecting irregular grinding when the maximum torque does not occur. Specifically, a tip dresser 18 includes a holder 27 holding a cutter 28, a servo motor unit 36 allowing the holder 27 to rotate, and a controller 50 controlling the operation of the servo motor unit 36. The servo motor unit 36 outputs a torque occurrence signal to the controller 50 when a load torque reaches a predetermined value in regular grinding of a pair of electrode tips 11. The controller 50 detects irregular grinding when not receiving the torque occurrence signal within a time that corresponds to an elapsed time in the regular grinding.

A small camera module is simply assembled in a short time, while reducing displacement of a camera relative to first and second frames. Specifically, the camera module 4 is assembled by bending a pair of clips 9 to engage engaging portions 9a of the clips 9 with engaging recesses 41c of the first and second frames 40a and 40b to fix the first frame 40a, camera holders 70, and the second frame 40b, with the first and second frames 40a and 40b located at both sides of each camera holder 70 with a housing recess 70c facing outward, and using resilient force of each of the clips 9 to press the camera 7 with a projection 9b of the clip 9.

In the present disclosure, a housing (4) has a housing passageway (R1) housing a plurality of electrodes (10) linearly therewithin. An electrode withdrawal opening (R2) communicating with the housing passageway (R1) is formed on one end of the housing (4). A pressing unit (5) presses toward one end of the housing passageway (R1) the plurality of electrodes (10) arranged side by side and housed in the housing passageway (R1). A lever member (6) is swung to switch between a state where withdrawal of the electrode (10) from the electrode withdrawal opening (R2) is restrained and a state where the electrode withdrawal opening (R2) is exposed. A regulating coil spring (7) urges and swings the lever member (6) to one side.
摘要:
A pressing unit (5) presses a plurality of electrodes (10) housed in a housing path (R1) in a housing case (2) toward an electrode outlet port (20). When a lever member (3) swings to one side, a distal end of the lever member (3) comes to be in a first position (X1) in which the lever member (3) covers a part of the electrode outlet port (20). When the lever member (3) swings to the other side, the lever member (3) comes to be in a second position (X2) in which the distal end exposes the electrode outlet port (20). A first coil spring (4) is disposed between a proximal end of the lever member (3) and a first side surface portion (21) of the housing case (2), and biases the proximal end of the lever member (3) to a direction away from the housing case (2).
