Abstract

The invention discloses a vacuum clamp for machining a thin-plate type part, comprising a bottom plate provided with a smooth upper surface, wherein the bottom plate is machined with a worktable connecting hole; a vacuum adsorption groove is machined in the bottom plate; the vacuum adsorption groove is an annular groove which is matched with the edge of the bottom plate in shape; a region surrounded by the vacuum adsorption groove is provided with at least one communication groove which is communicated with the vacuum adsorption groove; the vacuum adsorption groove is internally provided with a plurality of groove control holes connected with a vacuum pump; each groove control hole is provided with a sealing plug; and the sealing plugs are detachably connected with the groove control holes. According to the vacuum clamp disclosed by the invention, the principle of the vacuum pump is utilized to adsorb a part to be machined on a vacuum clamp; and when being machined, the part is machined according to the size, so that the higher machining precision is achieved.

Description

technical field [0001] The invention relates to a fixture, in particular to a vacuum fixture for processing thin plate parts used on a numerically controlled milling machine. Background technique [0002] In the existing machining industry, there are many thin plate parts of metal or non-metallic materials. Due to the low rigidity of the parts and the very thin parts required, the use of traditional fixtures for workpieces in the clamping force, cutting force Under the action of factors such as cutting vibration and cutting vibration, the parts are deformed after processing, which cannot meet the processing accuracy; and when the thickness of the plate parts is thin, the existing machine tool fixtures cannot clamp the parts to be processed on the CNC milling machine, and cannot achieve thinner thickness. machining of parts. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above problems in the prior art, and to provide a vacuum fix...
