Abstract

The invention discloses a hardware end face grinding fixture and a hardware end face grinding machine. The grinding fixture comprises a chuck, a main shaft, a bearing block, a rotating disk, a clamping board and at least two clamping pins, wherein the main shaft is supported by a bearing in the bearing block, the clamping board is arranged behind the rotating disk, the clamping board comprises clamping pin holes corresponding to the clamping pins, the rotating disk comprises clamping pin holes corresponding to clamping pins; the rotating disk is fixedly arranged at the front end of the main shaft; the chuck is shaped as a disk, the disk-shaped chuck comprises a plurality of workpiece supporting holes with forward openings; and the clamping pins are fixed on the chuck and extend backwards,and are clamped with clamping pin holes on the clamping board after passing through clamping pin guide holes of the rotating disk. The invention has the advantages of high production efficiency, highyield and improved product accuracy and external quality.

Description

[technical field] [0001] The invention relates to grinding equipment, in particular to a hardware part end surface grinding fixture and a hardware part end surface grinding machine. [Background technique] [0002] The end face of the head of some hardware parts needs to be processed with sandpaper to improve the finish. The traditional method is to manually grind on the grinding wheel of the grinding machine with sandpaper. The traditional fixture can only clamp one part at a time, and the fixture is pushed forward and backward along the horizontal guide rail of the grinder by hand to grind. The main disadvantages are: [0003] The fixture clamps a single part, and the production efficiency is low. An operator can only produce 1,000 pieces a day. [0004] Manually push the jig back and forth. It is difficult to control the amount of grinding, the processing accuracy is not high, the accuracy can only reach 0.1 mm, and the perpendicularity between the end face and the part...
