Auxiliary clamp for grinding mobile phone component

Abstract

The invention discloses an auxiliary clamp for grinding a mobile phone component. The auxiliary clamp comprises a bottom plate, a bracket, a main shaft, a shaft sleeve and a fixed plate for fixing a product, wherein the bracket is fixed on the bottom plate; the shaft sleeve is fixedly connected with the bracket; the main shaft is embedded into the shaft sleeve and is connected with the fixed plate; an outwards protruding part is arranged at one end of the main shaft along the circumferential direction; the outwards protruding part is fixedly connected with the fixed plate; an inner groove is formed in the inner side surface of each of the front end and the rear end of the shaft sleeve; the auxiliary clamp further comprises a plurality of locking cylinders; a plurality of circular slots forinserting piston rods are formed in the rear surface of a connection plate of the fixed plate; an insert bush is arranged in each of the multiple circular slots; the insert bushes are embedded into the circular slots, and are in contact connection with the circular slots; a chamfering slot is formed in the outer end surface of each insert bush; and chamfering parts corresponding to the chamferingslots of the insert bushes are arranged at the front ends of the piston rods of the locking cylinders. The auxiliary clamp for grinding the mobile phone component well fixes a product in a vacuum suction manner, is accurate in positioning and convenient to pick and place, and can save the time and improve the working efficiency.

Description

technical field [0001] The invention relates to an auxiliary fixture used for grinding mobile phone parts, and relates to the field of high precision machining. Background technique [0002] At present, most of the appearance structural parts / accessories of mobile phones on the market are made of metal materials. The forming of metal materials mainly includes aluminum extrusion, die-casting, forging and other methods. No matter which forming method is used, it needs to be processed by CNC machining center after forming. There are poor appearance phenomena such as knife marks and scratches in the workpiece, and a series of appearance retreatments such as passivation, grinding and polishing, spraying, and anodizing are required for the workpiece. For the grinding of metal structural parts such as the middle frame of the mobile phone, the side of the protective case of the mobile phone, etc., in actual operation, the staff needs to hold each piece of poor-looking workpiece in t...
