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).

摘要： A compressed air introduction part (5) capable of introducing compressed air into an air passage (2a) of a cylinder body (2) is provided. The compressed air introduction part (5) has a compressed air exit port (5a) formed in the shape of a ring that extends circumferentially about a cylinder-center axis (C1) of the cylinder body (2). An annular protuberance surface portion (30) is formed on an inner circumferential surface forming the air passage (2a) on an air blowout port (2c) side of the compressed air exit port (5a), and a protuberance surface (30a) of the annular protuberance surface portion (30) is shaped so as to extend from a peripheral edge portion of the air blowout port (2c) side of the compressed air exit port (5a) along the radial direction of the cylinder body (2) and to then gradually curve and extend toward the air blowout port (2c) side.

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 positioned adjacent to a rotating plate in a direction of a rotation axis is configured to allow the rotating plate to abut against an electrode housed and held in a first recess or a second recess and thereby to regulate a rotation of the rotating plate toward one direction around the rotation axis when the rotating plate rotationally biased by a spiral spring 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.

摘要： A rotary work device includes: a first output gear into which a holder is fitted; a second output gear into which a cutter is fitted; a second intermediate gear meshing with both the output gears; and a servomotor rotating the second intermediate gear. A control panel includes a memory storing a first rotational speed and a second rotational speed that is higher than the first rotational speed. When an electrode detachment operation is performed, both the output gears are rotated at the first rotational speed, and when an electrode cutting operation is performed, both the output gears are rotated at the second rotational speed.

摘要： The present disclosure reduces equipment failures, decreases maintenance frequency, and stabilizes cutting operation. Specifically, a holder (5) includes a fitting surface (52) capable of fitting a distal end (2a) of an electrode tip (2). A cutting member (6) having a cutting blade (6b) is attached to the holder (5) and the cutting blade (6b) cuts the distal end (2a) of the electrode tip (2) by rotating the holder (5). On the fitting surface (52), a plurality of grooves (52a) extending arcuately around the rotation axis (C1) as the center thereof are consecutively formed adjacent to each other toward the rotation axis (C1).

摘要： 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： 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 includes a holder holding a cutter, a servo motor unit allowing the holder to rotate, and a controller controlling the operation of the servo motor unit. The servo motor unit outputs a torque occurrence signal to the controller when a load torque reaches a predetermined value in regular grinding of a pair of electrode tips. The controller 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 cutter includes a pair of recessed receivers which receive the respective tip ends of a pair of electrode tips, and a through portion which runs through in a rotation axis direction and provides an opening that communicates with each of the recessed receivers. A cover case covers the lower recessed receiver of the rotary cutter and has a notch which is associated with the lower recessed receiver. Over the upper recessed receiver of the rotary cutter, a cover plate is fixed to cover the upper recessed receiver. An electrode tip insertion hole is cut through a center portion of the cover plate.
