摘要
The present disclosure relates to a continuous compression wire spring polishing apparatus that continuously polishes end surfaces of compression wire springs (10) by upper and lower chain conveyers 100 and 200 and grinding units 300. The apparatus includes: two grinding units (300) each having a grindstone (350) to which rotational force of a motor (240) is transmitted through a gear box (260), the motor (240) having a rotary shaft being located above a central axis of the grindstone (350), and the two grinding units (300) being installed to be parallel and opposite to each other at opposite sides of a compression wire spring (10) fixed to the continuous compression wire spring polishing apparatus so as to polish opposite end surfaces of the compression wire spring (10); two hinge shafts (140), which are fixed at positions, which are spaced apart from grindstones in the lowest surface of the grinding units (300) by a predetermined distance, and which are inserted into and coupled to bearings, which are fixed to a body of the polishing apparatus; an upper guide (225) configured to prevent the compression wire spring (10) from springing out and a rod end fixing shaft (150) fixed to an end of the cylinder rod (170) of the pneumatic cylinder (180) inserted into and coupled to a bearing fixed at a position between the grindstone rotation shaft and the hinge shaft (140) in each of the grinding units (300). The grindstone rotation shaft of each of the grinding units (300) is turned into the vertical state or the horizontal state according to the forward and backward movements of the pneumatic cylinder (180), so that the two grindstones (350) of the grinding units (300), which are mounted to be parallel and opposite to each other, can be easily replaced.
