Definitions
- the present invention relates to a cutting cutter for tip dress used for cutting the tip of an electrode tip for spot welding.
- the tip of the electrode tip used for spot welding is worn or worn by a predetermined number of times, or the state deteriorates due to the adhesion of an oxide film, etc., so the tip is periodically cut using a tip dress. There is a need.
- chips generated when cutting the tip part of the electrode tip contact the tip part of the electrode tip when it is scraped off by the cutting edge part of the tip dress, or the part is damaged or entangled in the apparatus. Since there is a possibility, it may be bent and rounded (or broken) immediately after being cut out by a portion called a breaker.
- the cutting cutter for chip dress disclosed in Patent Document 1 includes a substantially C-shaped holder in a plan view in which the rotation axis extends in the vertical direction.
- the holder is formed with a notch recess that opens to the outside and extends in the up-down direction and opens at both the upper and lower sides, and an attachment surface that extends along the longitudinal direction of the holder is formed on the inner surface of the notch recess.
- the upper and lower surfaces of the holder are formed with a pair of curved surface portions that gradually reduce in diameter toward the central portion of the holder, and the shape of each curved surface portion is an electrode chip in which the central axis coincides with the rotation axis of the holder It corresponds to the shape of the tip.
- a cutting plate having a pair of cutting blade portions corresponding to the shape of each curved surface portion is attached to the attachment surface, and the cutting plate and the breaker are fastened to the attachment surface with screws. Then, by rotating the holder while receiving the tip portion of the electrode tip at each of the curved surface portions, the tip portion of the electrode tip was cut by the cutting blade portion of the cutting plate, and was cut out by the cutting blade portion. The breaker bends the chips.

- the third invention is characterized in that, in the first or second invention, the outer peripheral portion of the breaker is provided with an inclined surface portion that gradually decreases in diameter toward the opposite side of the cutting plate.
- a countersink hole is formed around the through hole on the side opposite to the cutting plate of the breaker, and the head surface of the screw is opposite to the tightening direction.
- the depth of the countersink hole is such that when the breaker is attached to the cutting plate, the inclined surface portion and the head surface of the screw are substantially flush with each other. It is characterized by being set to.
- the breaker when the breaker is set at the mounting position of the cutting plate, a space is generated between the breaker through hole and the cutting plate by the concave surface portion of the breaker, so that the breaker is cut by inserting a screw through the through hole.
- the plate or the rotating body is tightened by screwing, the periphery of the breaker through hole is bent toward the cutting plate by the tightening force of the screw.
- a force directed toward the cutting plate is generated at the outer peripheral edge of the breaker due to the reaction caused by the periphery of the through hole being bent toward the cutting plate, and the outer peripheral edge of the breaker is pressed against the cutting plate, and the outer peripheral edge of the breaker There is no gap between the cutting plate. Therefore, chips are not caught between the cutting plate and the breaker, and the function of the breaker can be reliably achieved.
- the distance from the through hole to the outer peripheral edge of the breaker is uniform, when the periphery of the breaker through hole is bent toward the cutting plate by the screw tightening force, the distance from the outer peripheral edge of the breaker The force toward the cutting plate is uniform around the breaker. Therefore, it is possible to prevent a gap from being formed between the cutting plate and the outer peripheral edge of the breaker due to non-uniform force directed from the outer peripheral edge of the breaker to the cutting plate.
- the chips cut out by the cutting edge portion are gently bent by the inclination of the inclined surface portion, so that the chips are suddenly bent by the breaker and contact the tip of the electrode tip after cutting. Therefore, the cutting surface of the electrode tip can be kept clean.
- the chips scraped by the cutting edge portion are guided to the inclined surface portion and then smoothly get over the screw head. become. Therefore, it can be reliably avoided that the moving direction of the chips changes to the electrode tip side due to the head of the screw and contacts the tip of the electrode tip after cutting.
