Abstract

The invention provides a surface contact positioning pin and a manufacturing clamp thereof. A fixing groove is formed in one side surface of the surface contact positioning pin; an anti-rotation surface, a working surface, a second guide surface and a first guide surface are arranged on the other side of a positioning pin body from head to tail. A common standard round positioning pin is changed to be in a specific shape required for shape positioning of a product in a die, and the fixing groove is formed and can be matched with a bulge in the stamping die, so that a conventional line contact positioning pin can be changed to a surface contact positioning pin, the contact area of the positioning pin and the positioning part of the product can be enlarged, the product can be better positioned and fixed and is prevented from shifting, and the positioning pin is prevented from transversely rotating or axially moving in the die. The manufacturing clamp for manufacturing a positioning die is specially used for the surface contact positioning pin, the positioning pin can be better clamped, the required surface can be conveniently cut, the pertinence is strong, the processing time is greatly shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to a novel positioning pin and a fixture for manufacturing the positioning pin. Background technique [0002] In the prior art, positioning pins are widely used in mechanical assembly processes for positioning between parts and preventing relative displacement between parts. Since the standard locating pins in the prior art all have a unified general cylindrical shape, which is suitable for the positioning of round holes, if they cooperate with the planes of other components, it is difficult to completely contact and fit them. Especially for the precise positioning of the product shape in the stamping die, it is difficult for the traditional cylindrical positioning pin to completely fit the surface, resulting in unreliable positioning and low precision. As the domestic and foreign economic situation continues to change, it has had a huge impact on the manufacturing industry. How to effectively reduce manufacturing costs, increase...
