Abstract

The invention discloses a special clamp suitable for L-shaped valve body machining and a machining method. The special clamp comprises a main body, and a first clamping assembly, a second clamping assembly and a third clamping assembly are arranged on the main body; the first clamping assembly positions the second back face, the second bottom face and the second left side face of an L-shaped valvebody; the second clamping assembly positions the second left side face and the second right side face of the L-shaped valve body; and the third clamping assembly positions the second top face and thesecond bottom face. According to the clamp, the problem that a clamp needs to be frequently replaced when the L-shaped valve body is machined is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic parts processing, in particular to a special fixture and a processing method suitable for processing an L-shaped valve body. Background technique [0002] The L-shaped valve body used on the crane must ensure its accuracy during the production and processing process. Therefore, when processing the datum surface of the L-shaped valve body, the L-shaped valve body must be positioned. There are three processes in the processing of the L-shaped valve body. Different fixtures are used in different processes. Frequent replacement of fixtures is required in production, which increases costs. Contents of the invention [0003] The present application provides a special fixture and processing method suitable for L-shaped valve body processing, so as to solve the problem that the existing L-shaped valve body requires frequent replacement of fixtures. [0004] A special fixture suitable for processing a...
