Problems solved by technology

[0002] In mechanical processing, it is often necessary to support and clamp the workpiece before processing. When the workpiece, especially a large workpiece, needs to be supported by multiple support heads, and because the workpiece is often a blank surface, after the clamping force acts on the workpiece, due to each support head If the contact with the workpiece is not uniform, the workpiece will produce elastic deformation. After the clamping force is removed after processing, due to the recovery of elastic deformation, the processed surface will be distorted, resulting in a decline in the variety of the workpiece, or even scrapped

Embodiment Construction

[0008] When processing a blank workpiece, design a corresponding support fixture, which has multiple support heads, which can be used to support the workpiece. Due to the rough surface of the blank workpiece, the contact between the workpiece and each support head after clamping is supported by the support head The surface is not uniform. For this reason, each support head is installed on a plunger, and the plunger is installed on an oil cylinder, which is controlled by pressure oil. Each plunger can move up and down, and the control oil cylinders of each support head are supplied by the same oil pump. , so that the pressure is equal, and the pressure oil in each oil cylinder communicates; when there is no oil supply, the distance between each support head and the workpiece is roughly the same, and the pressure oil is supplied to the oil cylinder, and the plunger of each oil cylinder is pushed by the pressure oil to lift the workpiece. , each oil cylinder is equipped with a scr...

Abstract

A supporting method in the procedure of machining workpiece features that the workpiece is supported by a supporting fixture with multiple supporting heads installed on plungers (one on one), said plunger is installed in own's cylinder for controlling the height of plunger, and the pressure oil for all cylinders is supplied by one oil pump.

Description

technical field [0001] The invention belongs to the category of mechanical manufacturing, in particular to a supporting method in the process of workpiece processing. Background technique [0002] In mechanical processing, it is often necessary to support and clamp the workpiece before processing. When the workpiece, especially a large workpiece, needs to be supported by multiple support heads, and because the workpiece is often a blank surface, after the clamping force acts on the workpiece, due to each support head If the contact with the workpiece is uneven, the workpiece will produce elastic deformation. After the clamping force is removed after processing, due to the recovery of elastic deformation, the processed surface will be distorted, resulting in a decline in the variety of the workpiece, or even scrapping. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and disclose a support method in the...
