[0002] The seat belt tongue is an important component in the car seat belt system. It is usually used to connect the seat belt to the car seat fixing position. When the car collides or emergency brakes, the seat belt tongue can effectively lock the seat belt to ensure the safety of the passengers. Therefore, the quality and performance of the seat belt tongue are crucial to the safety of the overall seat belt system.

[0003] The existing seat belt lock tongue processing process mainly focuses on metal casting, forging or stamping processes, and the processing is completed after simple deburring and cleaning.

[0067] A round rod 812 is fixedly installed inside the shift plate 803, and a bent rod 809 and a square plate 807 are rotatably sleeved on the front and rear ends of the outer side of the round rod 812 respectively. The square plate 807 is slidably installed in the pressing plate 808, and a rotating frame 811 is fixedly installed on the front side of the connecting shaft 802. The bent rod 809 is slidably installed in the rotating frame 811. A compression spring 810 is fixedly installed on the top of the rotating frame 811, and the top of the compression spring 810 is fixedly connected to the bent rod 809.

[0068] In this embodiment, in step 2, a base 1 is provided at the bottom of the collection box 101 , and both sides of the collection box 101 are movably plugged into the corresponding vertical plates 501 , and the vertical plates 501 and the support rods 206 are fixedly mounted on the top of the base 1 .

[0069] In this embodiment, the raw material blank is placed on the mesh plate 505, and the height of the blank is adjusted by controlling the mesh plate 505 to rise and fall through the electric push rod 502. The two clamping motors 609 are started to drive the two screws 611 to rotate, and the two vertical plates 610 are close to each other. The two vertical plates 610 drive the two clamping plates 601 to approach each other, so that the first clamping pad 602 and the second clamping pad 605 are both in contact with the two sides of the raw material blank to achieve clamping, and the adjusting bolt 607 can be driven to rotate by rotating the knob 608, so as to adjust the position of the second clamping pad 605 separately to adapt to the size of different blanks.

[0070] The polishing motor 408 is started to drive the driving gear 407 to rotate forward, and the coarse polishing wheel 404 is driven to rotate through the meshing of the driving gear 407 and the large gear 406. At the same time, the driving gear 407 drives the fine polishing wheel 403 to rotate at high speed through the meshing with the small gear 405. The switching motor 410 is started to drive the rotating disk 402 to rotate, so that the coarse polishing wheel 404 contacts the blank to achieve coarse polishing. The driving motor 202 drives the screw rod 203 to rotate. The screw rod 203 drives the driving plate 204, the moving plate 301 and the mounting frame 401 to move horizontally through the threaded transmission with the driving plate 204, so that the coarse polishing wheel 404 rotates and moves horizontally at the same time to achieve automatic polishing. When the driving plate 204 moves, it drives the dial plate 803 to move synchronously. When the dial plate 803 contacts the dial column, the dial plate 803 rotates, thereby driving the round rod 812 to perform a circular motion, and the pressing plate 808 is driven to move horizontally through the cooperation of the square plate 807 and the pressing plate 808, and the round rod 8 When the circular motion is performed by 12, the bent plate can be driven to slide in the rotating frame 811 and the compression spring 810 can be compressed. When the round rod 812 is located directly below the rotating column 801, the compression degree of the compression spring 810 is relatively large. After the dial plate 803 continues to rotate, the elastic force of the compression spring 810 pushes the bent plate to perform a reset motion in the rotating frame 811 and can drive the pressing plate 808 to continue to move horizontally, and then the pressing plate 808 can switch with the pressing of the first switching button 804 and the second switching button 805. When the first switching button 804 is pressed, the polishing motor 408 and the driving motor 202 are controlled to rotate forward. When the second switching button 805 is pressed, the polishing motor 408 and the driving motor 202 are controlled to rotate reversely. Therefore, after the movable plate 301 moves to the specified position, the moving direction and the rotation direction of the rough polishing wheel 404 can be automatically switched. Therefore, when the rough polishing wheel 404 moves horizontally in the opposite direction, the relative movement speed between the rough polishing wheel 404 and the workpiece can be guaranteed to ensure the polishing effect.

[0071] The polishing liquid introduction pipe is connected to the liquid inlet of the pump body 704, and the water pump is started. The polishing liquid is introduced into the two injection tubes 701 through the feed pipe 703, and then sprayed out from multiple injection elbows 702 to form a lubricating film on the polishing contact surface, which can evenly distribute the abrasive particles so that it can work evenly on the workpiece surface, reduce local excessive wear, and reduce the surface temperature to avoid damage to the workpiece caused by overheating. At the same time, the sprayed polishing liquid can not only take away these debris, but also clean the polishing part to avoid the debris from having an adverse effect on the surface;

[0072] The monitoring mechanism 3 monitors the vertical pressure on the rough polishing wheel 404 through the pressure sensor 302, so as to judge the polishing condition, and accordingly control the switching motor 410 to operate, so as to realize the feeding of the rough polishing wheel 404 and realize uniform polishing. When the pressure sensor 302 detects that the pressure is reduced to the set value, the motor drives the rotating disk 402 to rotate, so that the fine polishing wheel 403 contacts the blank to realize fine polishing, and the rotation speed and horizontal movement speed of the fine polishing wheel 403 can be automatically switched through the switching mechanism 8. The vertical pressure on the fine polishing wheel 403 is monitored by the pressure sensor 302. When the extrusion force is less than the set value, it means that the blank has been polished to the right place, and the polishing is stopped.

[0073] The electric push rod 502 is started to drive the mesh plate 505 to move downward, thereby driving the support frame 504 and the mesh plate 505 to move downward to make room for the blank. Then the two rotating motors 603 are started to drive the two clamping plates 601 to rotate synchronously to control the blank to flip. Then the electric push rod 502 controls the mesh plate 505 to reset and support the blank again. The above steps are repeated to achieve polishing of the other side of the blank.

[0074] Then, the electric push rod 502 drives the screen plate 505 to move downward, and the two rotating motors 603 are started to drive the two clamping plates 601 to rotate synchronously to control the rotation of the finished product. The jet elbow 702 sprays the polishing liquid to fully rinse the finished product.

[0075] The above is a detailed introduction to the processing and polishing process of a safety belt lock tongue provided by the present invention. This article uses specific embodiments to explain the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention.
