Abstract

There is provided a fixed type electrode tip removal device capable of reliably removing an electrode tip and realizing full automation of the removal device. The fixed type electrode tip removal device for removing an electrode tip from the shank is made up of a take-out claw member provided with a substantially semi-circular claw for being brought into contact with an end face of the shank and an end face of the electrode tip in a gap between a large diameter portion of the shank and the electrode tip, the take-out claw member being disposed at the tip end of the removal device, wherein the end face of the electrode tip is pressurized by the claw in the direction of an axis of the electrode tip to remove the electrode tip from the shank, the take-out claw member being made up of a fixed take-out claw member fixed to a base plate and a movable take-out claw member movable relative to the base plate, a driving unit fixed to the base plate, a wedge connected to a pressure application rod from the driving unit, the wedge having a flat face at one side and a tapered inclined face at the other side, and an inclined face formed on the movable take-out claw member contacting the inclined face of the wedge.

Description

[0001] The present invention relates to a device for detaching from a shank a welding electrode tip taper-fitted on the shank. Background technique [0002] In the past, the device for dismounting the welding electrode tip taper-fitted on the shank from the shank, at the gap between the large diameter portion of the shank and the electrode tip, the end surface of the shank and the end surface of the electrode tip are respectively overlapped. A detachment claw member with a substantially semicircular claw is provided on the front end side of the detachment device, and the electrode tip is detached from the handle by pressing the end face of the electrode tip with the claw in the axial direction of the electrode tip. (For example, see Patent Document 1). [0003] Patent Document 1: [0004] Japanese Patent Laid-Open No. 2001-347380 [0005] However, what is disclosed in the above-mentioned background technology is a movable detachment device, which makes the electrode tip deta...
