Clamp for machining RV reducer pin wheel housing composite grinding machine

Abstract

The invention provides a clamp for machining an RV reducer pin wheel housing composite grinding machine. The clamp comprises a pin wheel housing, a plurality of cylindrical pins, a base and a flange,wherein the base is provided with a circular ring body and a plurality of supporting bodies extending in the longitudinal direction of one surface of the circular ring body, and every two adjacent supporting bodies are arranged in the circumferential direction in a spaced mode; the flange is provided with an outer ring body and an inner ring body extending out along the inner ring wall of the outer ring body, and a top plane of the outer ring body is higher than a top plane of the inner ring body; the circular ring body is locked to a workbench of the composite grinding machine through a plurality of fasteners, the fasteners penetrate through holes of the outer ring body to be locked to longitudinal holes of the corresponding supporting bodies, and the top plane of the outer ring body anda circumferential ring body of the pin wheel housing are fixed together; and one end of each cylindrical pin is in interference fit with a counter bore of the corresponding inner ring body, and the other end of each cylindrical pin is in interference fit with a workpiece of a hollow cylinder of the pin wheel housing. Compared with the prior art, the weight of the base can be reduced to a great extent, a crane is not needed for assembly, and production efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of part processing, and relates to a fixture used for processing a compound grinding machine for a needle-tooth case of an RV reducer. Background technique [0002] At present, in the prior art, there is a fixture for compound grinding machine processing of RV reducer pin gear housing, which includes: pin gear housing, which has a hollow cylinder and a circumferential ring protruding circumferentially along the side wall of the hollow cylinder; a straight pin. The existing problem is: for the above-mentioned fixture used for the processing of the compound grinding machine for the pin gear housing of the RV reducer, it needs to be assembled before use, limited by the structural limitations of the existing fixture device, the support part of the fixture device Both need to use a large disc with a large weight. Although the processing method of the fixture device is relatively simple, the large disc used will ...

The existing problem is: for the above-mentioned fixture used for the processing of the compound grinding machine for the pin gear housing of the RV reducer, it needs to be assembled before use, limited by the structural limitations of the existing fixture device, the support part of the fixture device Both need to use a large disc with a large weight. Although the processing method of the fixture device is relatively simple, the large disc used will increase the weight of the entire fixture device. When assembling the fixture, a crane is required to make the assembly of the fixture device Long time, resulting in low production efficiency
