Description

Technical Field

[0001] The invention relates to the technical field of polishing technology, and in particular to a processing and polishing process for a safety belt lock tongue. Background Art

[0002] The seatbelt tongue is a crucial component in the automotive seatbelt system, securing the seatbelt to the seat. In the event of a collision or emergency braking, the tongue effectively locks the seatbelt, ensuring passenger safety. Therefore, the quality and performance of the tongue are crucial to the safety of the entire seatbelt 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. However, due to insufficient surface treatment, some seat belt lock tongues have problems such as surface roughness, easy corrosion and wear, which not only affects their appearance quality, but also may affect their service life and reliability. Therefore, we propose a seat belt lock tongue processing and polishing process to solve this problem. Summary of the Invention

[0065] In this embodiment, in step 2, the switching mechanism 8 includes: a first switching button 804, a second switching button 805, a pressing plate 808, a guide frame 806, a rotating column 801, a connecting shaft 802, a dial plate 803, and two toggle columns.

The toggle columns are fixedly mounted on the front side of the fixed frame 201, the dial plate 803 is fixedly mounted on the front end of the rotating column 801, and the rotating column 801 and the connecting shaft 802 are both rotatably mounted within the driving plate 204.

[0066] The first switch button 804 and the second switch button 805 are both fixedly mounted with an arc-shaped plate at one end away from each other. The arc-shaped plate and the guide frame 806 are fixedly mounted on the top of the movable plate 301. The pressing plate 808 is slidably mounted in the guide frame 806.

[0067] A round rod 812 is fixedly installed inside the shift plate 803, and the front and rear ends of the outer side of the round rod 812 are rotatably sleeved with a bent rod 809 and a square plate 807 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.

[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 inserted 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 screen plate 505, and the height of the blank is adjusted by controlling the screen plate 505 to rise and fall by 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 brought closer to each other. The two vertical plates 610 drive the two clamping plates 601 to move closer to each other, so that the first clamping plate 602 and the second clamping plate 605 are both in contact with the two sides of the raw material blank to achieve clamping. The knob 608 can be rotated to drive the adjusting bolt 607 to rotate, so that the position of the second clamping plate 605 can be adjusted separately to adapt to the size of different blanks.

[0070] By starting the polishing motor 408, the driving gear 407 is driven to rotate forward, and the engagement of the driving gear 407 with the large gear 406 drives the coarse polishing wheel 404 to rotate. At the same time, the driving gear 407 drives the fine polishing wheel 403 to rotate at high speed through the engagement 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 movable 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 lever 803 is in the downward position, the spring 810 is pressed against the workpiece 804 to release the pressure, and the workpiece 804 is in the downward position, so that the workpiece 804 and the workpiece 804 can be rotated horizontally.

[0071] Connect the polishing liquid inlet pipe to the liquid inlet of the pump body 704, start the water pump, and introduce the polishing liquid into the two spray cylinders 701 through the feed pipe 703. Then, it is sprayed out from multiple spray elbows 702 to form a lubricating film on the polishing contact surface. This can evenly distribute the abrasive particles, allowing them to work evenly on the workpiece surface, reducing local excessive wear and lowering the surface temperature to avoid damage to the workpiece caused by overheating. At the same time, the sprayed polishing liquid can not only remove these debris, but also clean the polishing area to prevent the debris from having an adverse effect on the surface.

[0072] The monitoring mechanism 3 monitors the vertical pressure exerted on the coarse polishing wheel 404 through the pressure sensor 302, thereby judging the polishing condition, and accordingly controlling the switching motor 410 to operate, thereby feeding the coarse polishing wheel 404 and achieving uniform polishing. When the pressure sensor 302 detects that the pressure is reduced to a set value, the motor drives the rotating disk 402 to rotate, so that the fine polishing wheel 403 contacts the blank to achieve fine polishing. The rotation speed and horizontal movement speed of the fine polishing wheel 403 can be automatically switched by the switching mechanism 8. The vertical pressure exerted on the fine polishing wheel 403 is monitored by the pressure sensor 302. When the squeezing force is less than the set value, it indicates that the blank has been polished to the desired position, and polishing is stopped.

[0073] By starting the electric push rod 502 to drive the screen 505 to move downward, the support frame 504 and the screen 505 are driven 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 flipping of the blank. Then the electric push rod 502 controls the screen 505 to reset and support the blank again. The above steps are repeated to achieve the polishing work on 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 polishing liquid to fully rinse the finished product.

[0075] The above describes in detail the process for processing and polishing a seat belt lock tongue provided by the present invention.
