Problems solved by technology

[0003] The CNC process processes the thickness of the bracket and ensures the flatness of the large surface. The disadvantages: due to the small structure of the product and the unstable air pressure of the machine, during the processing, if the feed of the machine is large, the product will have the risk of displacement, resulting in A, B , The thickness and flatness of each plane of C are out of tolerance, the yield rate is low, and the production cost is high

Abstract

The invention discloses a multi-workpiece flat grinding jig and flat grinding equipment. The multi-workpiece flat grinding jig comprises a base and a plurality of station blocks, wherein the pluralityof station blocks are arranged on the end face of the base in a circumferential array mode, workpieces are placed on the end faces of the station blocks, and the end faces of the station blocks are distributed in a concave-convex mode corresponding to the shapes of the lower ends of the workpieces; and the flat grinding equipment comprises the multi-workpiece flat grinding jig and further comprises a rack, a driving device, a grinding disc and a limiting device. The jig is matched with the flat grinding equipment, so that the end faces of the workpieces can be flatly ground in batches, and the machine equipment cost, the clamp cost and the labor cost of a CNC procedure are reduced; after the product is flatly ground, the thickness and the flatness are ensured to be within tolerance, the yield is improved, and the production cost is saved; and CT machining is omitted, products are machined in batches in a flat grinding mode, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of CNC machining jigs, in particular to multi-workpiece flat grinding jigs and flat grinding equipment. Background technique [0002] The bottom surface A, B, and C of the camera bracket have different thicknesses and flatness. They are processed through the CNC process. The number of products processed each time is small, occupying a large number of machines, and requiring a lot of manpower; the air pressure of the CNC machine is unstable, which causes the positioning of the parts during the processing If there is a difference, the thickness & flatness of each plane of A, B, and C may be out of tolerance risk, resulting in rework or even product scrapping. [0003] The CNC process processes the thickness of the bracket and ensures the flatness of the large surface. The disadvantages: due to the small structure of the product and the unstable air pressure of the machine, during the processing, if the feed of...
