Automobile air conditioner compressor cylinder block boring machining tool

Abstract

The invention provides an automobile air conditioner compressor cylinder block boring machining tool. The automobile air conditioner compressor cylinder block boring machining tool comprises a bottomplate. A base is fixedly arranged in the middle of the bottom plate. A pressing air cylinder is fixedly arranged on the part, located on the periphery of the base, of the bottom plate. A pressing plate is connected with a piston rod of the pressing air cylinder. A positioning ring is fixedly arranged at the top end of the base. An elastic mandrel is fixedly arranged in the center of the positioning ring. A pushout ring is movably arranged on the periphery of the elastic mandrel in a sleeving mode. A lifting air cylinder is fixedly arranged in a center hole of the base. A mounting plate is horizontally and fixedly arranged at the piston end of the lifting air cylinder. A plurality of connecting rods are fixedly arranged on the mounting plate. The top ends of the connecting rods penetrate through the positioning ring and then make contact with the bottom end of the pushout ring. Through the tool, the compressor cylinder block boring machining precision and machining efficiency can be improved, the production cost is reduced, operation is simple, rapid and convenient, the product quality can be improved, and the actual application effect is good.

Description

technical field [0001] The invention relates to an automobile air-conditioning compressor, in particular to a boring processing tool for a cylinder body of an automobile air-conditioning compressor. Background technique [0002] The cylinder block is an important part of the automobile air-conditioning compressor, and the boring machining accuracy of the cylinder block is a key process that directly affects the service life and performance of the automobile air-conditioning compressor. At present, the clamping method used in the traditional cylinder boring process is to make the sealing surface of the cylinder close to the end surface of the positioning ring of the tooling, and then use the bearing hole and a process hole for positioning.

AI Technical Summary

Problems solved by technology

At present, the clamping method used in the traditional cylinder boring process is to make the sealing surface of the cylinder close to the end surface of the positioning ring of the tooling, and then use the bearing hole and a process hole for positioning. The high matching accuracy makes it difficult to take out the workpiece, which increases the clamping time of the workpiece and easily causes scratches to the bearing hole; at the same time, the positioning ring is likely to cause a backlog of aluminum chips, resulting in an out-of-poor verticality between the cylinder bore and the end face; at the same time When switching cylinder blocks of different models in the same series, the tooling will be switched due to the different shapes, which increases the switching of tooling when changing products, the time for debugging tooling and the cost of tooling

Combining the above factors, the traditional tooling is poor in versatility, and the labor intensity of the workers is high, which is easy to cause damage to the cylinder due to human factors.
