Problems solved by technology

[0002] During the processing of aluminum castings, the clamping and positioning of the product by the processing fixture has always troubled the industry; fatigue aging of the mold, mold repair, and product deformation caused by thermal expansion and contraction, etc., have caused the positioning of the product by the processing fixture. Clamping fails, and the defective rate of products remains high; this phenomenon is especially prominent for thin-walled products. How to solve this problem is the breakthrough that the industry has been looking for.

Embodiment 1

[0021] like Figure 1-2 As shown, a floating pin positioning device for product processing includes a gland 1, a positioning pin 2, a spring 3 and a processing tool reference hole, and the gland 1 is arranged on both shoulders of the positioning pin 2 to prevent The ejection of the positioning pin 2 can also be used as one of the plane references of the processing jig. The spring 3 is arranged in the positioning pin 2, and the positioning pin 2 is arranged in the reference hole of the processing jig. The positioning pin controls the positioning of the non-processing aperture of the product to achieve accurate positioning of the associated high-precision dimension processing parts. The tolerance of the sliding part of the jig template is: JIS B 0401 (1986) base shaft system / h6 .

[0022] The spring 3 controls the positioning pin 2 to maintain a directional force when the product is clamped. When the aperture position of the product deviates, it can be avoided or compensated a...
