Continuous compression line spring polishing device that can easily replace two whetstones mounted parallel and facing each other

摘要

The present invention provides a continuous compression line spring polishing apparatus including a grindstone exchanging device capable of easily exchanging a grindstone and shortening the replacement time. A continuous compression line spring polishing apparatus for polishing an end face of a compression line spring (10), wherein a rotation axis of the motor (240) is located above a central axis of the grindstone (350) and is parallel to both sides of the compression line spring (10). And two grinding units 300 provided so as to face each other, two hinge shafts 140 fixed at positions spaced apart from the grindstone on the lowermost surface of the grinding unit 300, and a grindstone rotating shaft and a hinge by the grinding unit 300 Including a load end fixed shaft 150 which is inserted into and coupled to a bearing fixed at a position between the shaft 140 and the pneumatic cylinder 170 is moved forward and backward so that the grindstone rotation shaft of the grinding unit 300 is in a vertical state or The two grindstones 350 can be easily exchanged so that they can be rotated horizontally.
