The pull-out type positioning pin and the tie-suspended type positioning pin are in the form of a straight cylindrical shape. The pull-out locating pin is temporarily pulled out from the connected piece of the tooling, and it is in a loose state; the tail of the tie-suspended locating pin is connected with a tie such as iron wire or string to the connecting piece of the tooling. After the locating pin is pulled out, the tie Suspended on tooling. The main disadvantages of the two types of positioning pins are as follows: First, the suspension straps are easy to fall off after long-term wear, and the pull-out positioning pins of the same parts are not convenient for on-site storage and placement, and are usually placed on the nearby ground at will; All kinds of positioning pins are prone to position transfer, forgetting and losing, which affects the reset of the tooling and the subsequent manufacture and assembly of aircraft products.

In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the slotting device 4 includes a motor 41 and a motor 43, the cutting wheel 42 is fixedly arranged at the output end of the motor 41, and the motor 41 drives the cutting wheel 42 to rotate to open the screw. slot, the motor 43 is fixedly arranged on the workbench 1, the motor 41 is arranged on the motor 43, a track 47 is arranged between the motor 41 and the motor 43, the motor 41 can reciprocate through the track 47, and when the screw is slotted, the motor 41 drives the cutting wheel 42 to move in the direction of the screw. When the slotting is finished, the motor 41 drives the cutting wheel 42 to retract. The fixed wheel 48 is arranged at the output end of the motor 43. The fixed wheel 48 is located directly below the cutting wheel 42. The surface of the middle screw is in contact, and the motor 43 drives the fixed wheel 48 to rotate to grind and polish the surface of the slotted screw to make the surface smooth. Preferably, the direction of rotation of the cutting wheel 42 and the fixed wheel 48 is opposite.

The pressure riveting nut, also known as the self-tightening nut, is a kind of nut applied to thin plates or sheet metal parts. To facilitate the installation of other parts on the printed circuit board. The conventional process is to design prefabricated holes on the printed circuit board in advance, and squeeze the rivet nut into the board through pressure, so that the periphery of the hole is plastically deformed, so that the rivet nut is firmly fixed on the circuit board. In important positions, the use environment of pressure riveting nuts is relatively harsh. In display products, due to space constraints, pressure riveting screws are used a lot. The riveting quality of pressure riveting screws has a direct impact on the reliability of the system. The riveting process is correct. The key technology of using rivet nuts.

Pins are frequently used parts in the machinery industry, especially in the mold manufacturing industry. With the development of the mold industry, the precision of mold manufacturing and assembly is getting higher and higher, and people are increasingly pursuing high-quality and close molds. Every detail on the mold is constantly improving, and the high-frequency use of the pins forces people to find a safer, simpler and more reliable way to disassemble and assemble.
