Description

Technical Field

[0001] The utility model belongs to the technical field of clamping tooling, in particular to a clamping tooling for aluminum alloy production. Background Art

[0002] After the aluminum alloy castings are cast, they need to be finished by machine tools;

[0003] As attached Figure 6 The aluminum alloy part shown is in the casting state on the left, and then the finished part on the right is obtained by lathe finishing. The bump in the figure is used as the protruding part of the part to cooperate with the clamping tool during finishing;

[0004] The finishing process of the part is as follows: first, the bump is clamped by the No. 1 fixture, and then the outer surface of the part and the circular hole are finish-machined. After completion, it is removed from the No. 1 fixture, turned over, and placed on the No. 2 fixture. The No. 2 fixture clamps the part from the inside through the circular hole, and then finish-machines it. After processing, it is removed from the No. 2 fixture.

[0005] In the above processing steps, the tooling generally clamps multiple parts, but each part uses an independent clamping mechanism, which makes the clamping and loosening operations more complicated. Secondly, after the first side is processed, the parts 7 need to be manually turned over and clamped again, which is cumbersome and increases the probability of parts falling, which is not conducive to efficient production.

[0006] In order to solve the above problems, this application proposes a clamping tool for aluminum alloy production. Utility Model Content
