Hydraulic clamp used for processing automobile protective support

Abstract

The invention discloses a hydraulic clamp used for processing an automobile protective support. The hydraulic clamp is positioned by a positioning shaft and a positioning key, is mounted on a horizontal type processing center and comprises a clamp body with a hydraulic oil path therein, a positioning shaft mounted on the clamp body in an interference fit mode, a positioning key in bolt connection as well as a right-angled surface positioning block and three diamond pins detachably mounted on the clamp body for positioning parts, and further comprises eight hydraulic floating supporting cylinders, nine hydraulic rod pressing cylinders and four piston type pressing cylinders connected onto the clamp body through cushion blocks, four steering pressing cylinders mounted on a right-angled surface for realizing a part pressing function, a pre-positioning block mounted on the right-angled positioning surface and another two pre-positioning rods mounted on the clamp body for realizing part pre-positioning and mechanical error-proofing functions, wherein components on the left and right parts are symmetrical, positioning and pressing mechanisms on the clamp body are symmetrically arranged left and right. Generality of the clamp body is realized.

Description

technical field [0001] The invention relates to the technical field of hydraulic clamps, in particular to a hydraulic clamp for processing automobile protection supports. Background technique [0002] In the prior art, the left / right protective bracket of the automobile - the connecting frame and the bracket are four parts combined into one part through structural optimization, and then connected to the frame by riveting and bolts, and the leaf spring is connected to the protective bracket - connecting frame and the frame through pins. The lifting lug part of the bracket is connected to support and fix the leaf spring; the traction hook is connected to the protective bracket-connecting frame and bracket through threads; the bumper is connected to this part through bolts, the quality of the protective bracket-connecting frame and bracket It will directly affect the performance of the leaf spring suspension and the assembly effect of the bumper. It is an important structural p...

AI Technical Summary

Problems solved by technology

The station process of processing protective bracket-connecting frame and bracket was originally processed by vertical machining center and ordinary milling machine. Each process of a product needs to use a set of fixtures, which requires a lot of investment in fixtures and equipment, and the cost of adjusting fixtures Time-consuming labor, resulting in large cost investment, and unstable machining accuracy
