Four-axis rough machining positioning and clamping device for compressor cylinder

Abstract

The invention relates to a four-axis rough machining positioning and clamping device for a compressor cylinder block, comprising a main board, a fixture plate, a pressure plate, an oil cylinder, a bottom claw positioning pin and a supporting positioning sleeve. A fixture plate is embedded in each of the installation hole slots, and a through hole is made in the center of each fixture plate. The front of each fixture plate is vertically installed with a bottom claw positioning pin and a support positioning sleeve. The main board on the outside of the fixture plate Three oil cylinders are installed on the cylinder, and a pressure plate is installed on the plunger rod of each oil cylinder, and the front ends of the three pressure plates are located above the clamp plate. The invention is a four-axis rough machining positioning and clamping device for a compressor cylinder block, which is reasonable in design, simple in structure, easy to manufacture, convenient in use, low in manufacturing cost and suitable for large-scale industrial production. Using the device can reduce the difficulty of clamping , Simplify work flow, improve machining accuracy, speed up production progress and reduce production cost.

Description

technical field [0001] The invention relates to a fixture in the technical field of compressor cylinder processing, in particular to a positioning and clamping device for four-axis rough machining of a compressor cylinder. Background technique [0002] The cylinder body of the compressor needs to be rough-machined on its upper surface, valve surface and high-pressure chamber surface. At present, the clamps used in processing are positioned with the bottom claws of the workpiece. When using this positioning method, it is necessary to press three points of the workpiece to ensure The stability of positioning is not easy to realize, and the processing accuracy cannot be guaranteed. In addition, the compressor cylinder is a thin-walled part. Due to its thin wall thickness, the workpiece is easily deformed when using ordinary processing methods, and it is difficult to complete the processing of three surfaces after one clamping. There is also the problem that the processing accur...
