Double-station rotary clamp for finish turning of semicircles of brake bases

Abstract

The invention provides a double-station rotary clamp for finish turning of semicircles of brake bases. The double-station rotary clamp comprises a disc, a connecting disc, a first oil cylinder seat, a second oil cylinder seat, a first positioning seat, a second positioning seat, a horizontal clamping device and a vertical clamping device, and is novel in structure and clear in operation principle. Compared with a device for finish turning of semicircles, two brake bases can be placed on the rotary clamp at the same time, the horizontal clamping device and the vertical clamping device are driven by a hydraulic control system to achieve fixing and clamping of the brake bases, finish turning machining of semicircles is completed, the double-station rotary clamp is simple and high in universality, the machining efficiency is greatly improved, and economic benefits are obvious.

Description

technical field [0001] The invention belongs to the field of automatic machinery, and relates to a double-station rotary fixture used for semicircular finishing of brake bases. Background technique [0002] At present, single-station rotary fixtures are usually used for the machining of the semicircle of the brake base. However, because the two ends of the semicircle and the middle part of the brake base, according to product performance requirements, the hardness formed after heat treatment is different. When using a single-station rotary fixture , single-piece processing takes a long time, the semicircle size cannot be measured online with measuring tools, the tool life is greatly reduced, and the scrap rate is greatly increased. For large-scale order requirements, this method of production processing cannot improve production efficiency. If more equipment Or increase the number of operators, which will undoubtedly increase the production cost, and the flexibility is low, ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problems of traditional brake base single-station rotary fixture processing, which cannot be used in mass production, low work efficiency, and poor flexibility. The hardness of the upper and lower ends of the semicircle is different from that of the middle part. The horizontal clamping device and the vertical clamping device are rotated 180° along the center of the disc and installed symmetrically in the center to form a double-station rotary fixture. The rotary fixture moves in the circumferential direction along the inner diameter of the semicircle to realize the semicircle finishing process of the brake base on the double station. It has strong flexibility and high efficiency and can meet the processing of large quantities of brake bases.
