Processing clamp for air compressor part of commercial vehicle

Abstract

The invention discloses a processing clamp for an air compressor part of a commercial vehicle, and relates to the technical field of air compressors. The processing clamp comprises a base, wherein a motor, a connecting base and a first connector are arranged at the upper side of the base; the output end of the motor is equipped with a processing assembly; one side of the connecting base is equipped with a limiting assembly; the limiting assembly is matched with the processing assembly; a slide assembly is arranged at the upper side of the first connector; a clamping assembly is placed at the upper side of the slide assembly; and the slide assembly is matched with the limiting assembly. Through the design of the processing clamp, a numerical-control processing center can be processed to a plurality of positions, so that multi-machine-tool processing cost is reduced, and the risk that processing precision is unstable is avoided.

Description

technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to a processing fixture for commercial vehicle air compressor components. Background technique [0002] Commercial vehicle air compressor components The crankcase is a typical box part. Its function is to accommodate and support all the parts in it, to ensure the correct position between them, and to coordinate and work with each other. The part of the lower part of the cylinder block used to install the crankshaft is called the crankcase, and the crankcase is divided into an upper crankcase and a lower crankcase. The upper crankcase is cast into one body with the cylinder block, and the lower crankcase is used to store lubricating oil and close the upper crankcase, so it is also called the oil pan. Cylinder block and crankcase are usually cast in one piece, called cylinder block-crankcase, this cylinder block is a relatively common structure in automobile engin...

Problems solved by technology

[0003] In the production process of the existing technology, the rough and fine machining processes of the main surfaces and holes are not separated, because the accuracy and performance of the air compressor components have a certain impact on the stability of the commercial vehicle, and the quality of the commercial vehicle also affects the ride quality. For the safety of personnel, there are many surfaces and holes that need to be processed from the blank to the finished product of commercial vehicle air compressor components, and they are not on the same plane and at the same angle, and these planes and holes have associated size restrictions

If it is processed on different machine tools, it is necessary to design various fixtures. Using different fixtures for each machining will result in different positioning references and reference surfaces each time. The machining accuracy cannot be guaranteed, and the associated dimensions cannot be stable. And it will increase the input cost of various machine tools and fixtures
