Special clamp for hole boring and machining of special-shaped part

Abstract

The invention discloses a special clamp for hole boring and machining of a special-shaped part. The special clamp comprises a flange plate, a limiter, a fast clamping mechanism and an adjustable locator; the flange plate is fixedly connected to machining equipment through fastening screws and is fixedly connected to the limiter and the adjustable locator, the limiter and the adjustable locator are used for effectively locating the special-shaped part, and the fast clamping mechanism is arranged at the part, right opposite to the limiter, of the flange plate. The special clamp for hole boring and machining of the special-shaped part has the advantages that the manufacturing cost of the clamp is low, the manufacturing difficulty of the clamp is low, maintenance is convenient, the maintenance cost is low and adjustment of the clamp is fast and effective, can fast clamp parts to be machined and is convenient to maintain later, the parts can be effectively located, the problem that the clamping force of special clamps in the prior art is insufficient can be solved, the relevant dimensions of the machined surface and the non-machined surface of the special-shaped part can be stable and reliable, and the part appearance is free of deformation or impressions. In addition, the special clamp is suitable for mass production and can effectively lower the production cost.

Description

technical field [0001] The invention belongs to the technical field of special fixtures for mechanical processing, and in particular relates to a special fixture for boring holes of special-shaped parts. Background technique [0002] Such as Figure 5 to Figure 6 As shown, the processed special-shaped part 1 is an elliptical sheet-shaped part, and a large through-hole and a small through-hole are respectively opened on the special-shaped part 1. During the machining process, the special-shaped part 1 needs to be bored. However, The main defects and deficiencies of the special jig for boring processing in the prior art are: the special jig for boring processing in the prior art has the advantages of high jig manufacturing cost, high jig maintenance cost, complicated jig adjustment, and parts positioning. Defects, slow clamping speed, unstable clamping force, unstable dimensions after processing, and parts are easily pinched. The special fixtures for special-shaped parts borin...

Problems solved by technology

[0002] like Figure 5 to Figure 6 As shown, the processed special-shaped part 1 is an elliptical sheet-shaped part, and a large through-hole and a small through-hole are respectively opened on the special-shaped part 1. During the machining process, the special-shaped part 1 needs to be bored. However, The main defects and deficiencies of the special jig for boring processing in the prior art are: the special jig for boring processing in the prior art has the advantages of high jig manufacturing cost, high jig maintenance cost, complicated jig adjustment, and parts positioning. Defects, slow clamping speed, unstable clamping force, unstable dimensions after processing, and parts are easy to be pinched. The special fixtures for special-shaped parts boring processing in the prior art cannot adapt to mass production, resulting in excessive production costs. Therefore, it is urgent to design a special jig for boring machining of special-shaped parts with low production cost, convenient use and low maintenance cost.
