摘要： 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).

摘要： 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).

摘要： 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.

摘要： 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.

摘要： A rotary holder (2) and a cutting component (3) are prepared. The rotary holder (2) can receive a spot-welding electrode tip (11). The cutting component (3) has a cutting edge (3d) and a flank surface (3b). A receiving surface (2c) and the flank surface (3) are treated by blasting to form a rough surface (2d, 3e). The cutting component (3) and the rotary holder (2) are then attached to a tip dresser (10). The electrode tip (11) is received by the receiving surface (2c) and the flank surface (3b) while the rotary holder (2) is rotating to cut and reshape a tip end (11a) of the electrode tip (11) with the cutting edge (3d).
