[0002] Flat pins are a type of mechanical connector, commonly used in mechanical devices or equipment to position and fix. They are usually not in the shape of a standard circle, but with a flat portion. This flat design allows them to effectively prevent themselves from rotating after installation, thereby better achieving the function of precise positioning. Flat pins are often used in some equipment that requires precise assembly and requires parts to be fixed in relative position, such as various machine tools, and some component connections of automated production lines, to ensure the connection stability and position accuracy between related parts.

It is designed with double-ended flat positions, which greatly improves the assembly accuracy requirements of the assembly equipment, and simultaneously optimizes the assembly accuracy of the final product, improves the terminal customer experience, and uses the cold heading production process for production development.

[0018] 2. The present invention sets a flat pin body, first moves the stabilizing cover, so that the stabilizing cover drives the sliding rod to move inside the moving groove, and then the sliding rod drives the top plate on its outside to move toward the outside of the fixed plate. When the top plate moves to the required position, the flat pin body is installed on the outside of the device, and then the screw is rotated to make the screw rotate and move inside the threaded tube, and the positioning rod is driven to move by the movement of the screw, so that the positioning rod is moved to the outside of the fixed plate, so that the stabilizing cover is fixed.

[0019] 3. The present invention provides a flat pin body, and an elastic oil bag is installed inside the flat pin body. When the flat pin body is connected to the device for too long, rust will occur or separation will be difficult. At this time, the transmission rod and the return spring are used in conjunction to move the transmission rod back and forth inside the U-shaped frame, and the movement of the transmission rod drives the extrusion rod to move, so that the extrusion rod squeezes the elastic oil bag inside the flat pin body, and the lubricant inside the elastic oil bag enters into the oil outlet hole through the oil outlet pipe. The oil outlet holes are distributed in the No. 1 flat slot, the No. 2 flat slot, the No. 3 flat slot and the No. 4 flat slot. Therefore, the lubricant will enter the connection between the outer device and the flat pin body, thereby performing lubrication. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] like Figures 1 to 7 As shown, the present invention provides a double-headed flat position pin and a positioning mechanism, including a flat position pin body 1, wherein the flat position pin body 1 is provided with a first flat position slot 2, a second flat position slot 3, a third flat position slot 4 and a fourth flat position slot 5, and a clamping mechanism 6 is provided on the outer side of the flat position pin body 1;

[0037] It is worth emphasizing that since an oil inlet is provided on the outside of the elastic oil bag 71, lubricant can be added to the inside of the elastic oil bag 71, and at the same time, the oil outlet hole 73 is located inside the No. 1 flat groove 2, the No. 2 flat groove 3, the No. 3 flat groove 4 and the No. 4 flat groove 5, so the lubricant inside the elastic oil bag 71 will enter the No. 1 flat groove 2, the No. 2 flat groove 3, the No. 3 flat groove 4 and the No. 4 flat groove 5 through the oil outlet hole 73.

[0038] Among them, the structure of the motor is the prior art and will not be described in detail. At the same time, the present invention also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in the present invention belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0039] Working principle and process: By setting a flat pin body 1, a No. 1 flat slot 2, a No. 2 flat slot 3, a No. 3 flat slot 4 and a No. 4 flat slot 5 are opened in the outer wall of the flat pin body 1, and a double-head flat position is designed to greatly improve the assembly accuracy requirements of the assembly equipment, and simultaneously optimize the assembly accuracy of the final product, improve the end-customer experience, and use the cold heading production process for production development. The new development route not only achieves high processing efficiency, but also innovates the processing technology direction of special-shaped parts in cold heading forming. By setting the flat pin body 1, first, by moving the stabilizing cover 65, the stabilizing cover 66 is 5 drives the slide bar 64 to move inside the moving groove 63, and at this time the slide bar 64 drives the top plate 610 on its outer side to move to the outer side of the fixed plate 62. When the top plate 610 moves to the required position, the flat pin body 1 is installed on the outer side of the device, and then the screw rod 68 is rotated to make the screw rod 68 rotate and move inside the threaded tube 67. The movement of the screw rod 68 drives the positioning rod 69 to move, so that the positioning rod 69 moves to the outer side of the fixed plate 62, so that the stable cover 65 is fixed. At this time, the top plate 610 can maintain stability on the outer side of the fixed plate 62, and then the electric start is started. The telescopic rod 614 is used to drive the push rod 615 to move. At this time, the push rod 615 will push the positioning plate 613 on the outside of the moving rod 612, so that the positioning plate 613 moves to the outside of the device under the action of the moving rod 612 and its outer spring, thereby clamping the flat pin body 1 connected to the outside of the device to prevent it from falling off during long-term work. By setting the flat pin body 1, an elastic oil bag 71 is installed inside the flat pin body 1. When the flat pin body 1 is connected to the device for too long, it will rust or be difficult to separate. In this case, the transmission rod 75 and the return spring 76 are used in conjunction to make the transmission rod 75 move back and forth inside the U-shaped frame 74, and the movement of the transmission rod 75 drives the extrusion rod 77 to move, so that the extrusion rod 77 squeezes the elastic oil bag 71 inside the flat pin body 1, and the lubricant inside the elastic oil bag 71 enters the oil outlet hole 73 through the oil outlet pipe 72. The oil outlet holes 73 are distributed in the No. 1 flat slot 2, the No. 2 flat slot 3, the No. 3 flat slot 4 and the No. 4 flat slot 5. Therefore, the lubricant will enter the connection between the outer device and the flat pin body 1 for lubrication.
