Simple center size out-of-tolerance detection jig

Abstract

The invention relates to a simple center size out-of-tolerance detection jig, which includes a test board, a measuring rod and a fixture. A measuring rod support seat is arranged on the left positionof the rear end of the test board, the measuring rod penetrates through the measuring rod support base from back to front, and a measuring head is arranged at the front end of the measuring rod; the fixture includes a triangulation location block arranged on the front side of the test board; a positioning block is arranged on the position, on the front part of the triangulation location block, ofthe test board, and a first support column, a second support column, and a third support column which are in triangular arrangement are arranged on the position, outside the triangulation location block, of the test board; and the fixture further includes a clamp, and the lower pressing end of the clamp is located on the upper part of the triangulation location block. According to the simple center size out-of-tolerance detection jig, a product is positioned and clamped on the test board through the fixture and inserted into a hole B by sliding the measuring rod, if the product can be fully inserted, the product is qualified, if not, the center size is out of tolerance, test results are accurate, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the field of detecting the central dimension of aluminum alloy die-casting parts, in particular to a simple center dimension out-of-tolerance detection jig. Background technique [0002] Such as Figure 7 The product shown has hole A in the up-down direction and hole B in the left-right direction. The center distance h between hole A and hole B must meet the standard. However, since hole B needs to be pulled out when the die-casting is performed, hole A must be pulled out. The distance from the center of the hole B is occasionally out of tolerance, so in order to ensure the quality of the product, it is necessary to detect the center distance, and how to detect is the problem to be solved at present. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a simple central dimension out-of-tolerance detection fixture, the product is positioned and clamped on t...

[0002] like Figure 7 The product shown has hole A in the up-down direction and hole B in the left-right direction. The center distance h between hole A and hole B must meet the standard. However, since hole B needs to be pulled out when the die-casting is performed, hole A must be pulled out. There are occasional out-of-tolerance phenomena in the distance from the center of hole B, so in order to ensure the quality of the product, it is necessary to detect the center distance, and how to detect is the problem to be solved at present
