[0002] During the production and assembly of automobiles, various tubular components are often used. The top-mounted tube is a type of tubular component used in the automotive safety system. During the manufacturing process of the top-mounted tube, its end parts need to be polished. A smooth end after polishing is more conducive to the subsequent smooth assembly of the top-mounted tube.

[0003] Patent publication number CN221517129U discloses a grinding table for automotive pipe fitting ports, including a worktable for processing automotive pipe fitting ports. A processing box is fixed to the surface of the worktable, and a fixing component is set inside the processing box. An adjustment structure is set on the surface of the fixing component, and a limit mechanism is set on the surface of the adjustment structure. An output device is set inside the processing box, and a grinding component is set on the surface of the output device. The fixing component includes a slide rod, a slide plate, and a rotating shaft. The slide rod is fixed inside the processing box, and the slide plate is slidably connected to the surface of the slide rod. The rotating shaft passes through the interior of the slide plate, and the end of the rotating shaft passes through the side wall of the processing box. A knob is fixed to the end of the rotating shaft. Through the cooperation of the processing box and the fixing component, the device can intercept the sputtered sparks during use, thereby solving the problem that existing devices are prone to affecting construction safety due to spark sputtering.

The conveyor belt 396 is located on the outer side of the conveyor roller 397 and is in contact with the outer surface of the conveyor roller 397. A socket 398 is fixedly connected to the outer side of the conveyor belt 396. A new grinding rod 393 is inserted into the socket 398 on the outer side of one of the conveyor belts 396 for backup. When in use, the grinding rod 393 is installed at the bottom of the mounting rod 392. After the grinding rod 393 rotates, it can grind the pipe end. The outer side or the inner side of the insertion port are used to evenly grind both the inner and outer sides of the pipe fitting. When it is necessary to replace the grinding rod 393, the old grinding rod 393 is inserted into the socket 398 on the remaining conveyor belt 396. The installation rod 392 is then swung to align with the side of the socket 398 that stores the new grinding rod 393 before insertion. This allows for quick docking and installation of the installation rod 392 and the grinding rod 393, thus completing the replacement quickly. Compared to manual replacement, this method is more labor-saving and convenient, and helps to ensure grinding efficiency and grinding quality.

[0049] The socket 398 has a slot 399 that matches the polishing rod 393. The mounting rod 392 has two trapezoidal blocks 381 that slide inside.

The mounting rod 392 has two first springs 382 that are fixedly connected inside. The two first springs 382 are fixedly connected to one side of the two trapezoidal blocks 381 respectively. After the trapezoidal blocks 381 extend through the slot, the locking purpose of the mounting rod 392 and the rectangular plug frame 394 after installation can be completed.

[0050] The sockets 398 are arranged at equal intervals on the outside of the conveyor belt 396. Two fixing blocks 383 are provided inside the sockets 398. A limiting plate 384 is fixedly connected to the fixing blocks 383. The limiting plate 384 extends out of the outside of the sockets 398.

A first cylinder 389 is fixedly connected to the top of the main plate 2. The top of the first cylinder 389 is fixedly connected to the top of the inner side of the guide plate 33. After the first gear 388 rotates, it drives the gear ring 386 to rotate. A threaded control rod 371 is rotatably connected inside the rectangular frame 34. The threaded control rod 371 passes through the moving block 35 and is threadedly connected to the moving block 35. A third motor 372 is fixedly connected to the outer side of the rectangular frame 34. The third motor 372 is fixedly connected to one end of the threaded control rod 371 through its output shaft. After the third motor 372 works, it drives the threaded control rod 371 to rotate, and the threaded control rod 371 drives the moving block 35 to move horizontally.

[0052] A positioning plate is fixedly connected to the inner side of the frame plate 36, and a movable plate 375 is slidably connected to the outer side of the positioning plate. A second cylinder 374 is fixedly connected to one side wall of the frame plate 36. One end of the second cylinder 374 is fixedly connected to one side of the movable plate 375. A rack 373 is fixedly connected to the bottom of the movable plate 375. A third gear 376 is fixedly connected to the outside of the shaft 38. The rack 373 is located on the top of the third gear 376 and meshes with the third gear 376. After the rack 373 moves horizontally, the rack 373 drives the third gear 376 to rotate.

[0053] An auxiliary frame 377 is fixedly connected to one side wall of the main body plate 2. Two threaded blocks 378 are slidably connected inside the auxiliary frame 377. A pressing rod 379 is fixedly connected to one side of the threaded block 378. The pressing rod 379 extends to the inner side of the main body plate 2. The two pressing rods 379 are respectively set on the front and rear sides of one of the conveyor belts 396. The pressing rod 379 can push the trapezoidal block 381 into the mounting rod 392, thereby smoothly completing the disassembly between the mounting rod 392 and the rectangular plug frame 394. A bidirectional threaded rod 361 is rotatably connected inside the auxiliary frame 377. The bidirectional threaded rod 361 passes through the two threaded blocks 378 in sequence, and the bidirectional threaded rod 361 is connected to the two threaded blocks 378 by threads. A fourth motor 362 is fixedly connected to the outside of the auxiliary frame 377. The fourth motor 362 is fixedly connected to one end of the bidirectional threaded rod 361 through the output shaft. The threads at both ends of the bidirectional threaded rod 361 are opposite in direction, which can drive the two threaded blocks 378 to move towards or away from each other.

[0054] A square plate is fixedly connected to the top of the main body plate 2. A fifth motor 363 is fixedly connected to the square plate. The fifth motor 363 is fixedly connected to one end of one of the conveyor rollers 397 through its output shaft. Pulleys 364 are provided on the front side of the two conveyor belts 396. The two pulleys 364 are fixedly connected to the outside of the two conveyor rollers 397 respectively. The two pulleys 364 are connected by a belt. The fifth motor 363 drives the connected conveyor rollers 397 to rotate. Under the transmission action of the two pulleys 364, the two conveyor belts 396 can rotate synchronously.

[0055] A clamping assembly 4 is provided on the inner side of the main body plate 2. The clamping assembly 4 includes a connecting plate 41, which is located on the inner side of the main body plate 2. A third cylinder 42 is fixedly connected to both sides of the inner side of the connecting plate 41. A clamping plate 43 is fixedly connected to one end of the third cylinder 42. The clamping plate 43 is slidably connected to the inner side of the connecting plate 41. Round rods 44 are fixedly connected to both sides of the connecting plate 41. One end of each round rod 44 is rotatably connected to the two side walls of the main body plate 2. A sixth motor 45 is fixedly connected to one side wall of the main body plate 2. A fourth gear 46 is fixedly connected to the sixth motor 45 through an output shaft. A fifth gear 47 is fixedly connected to the outer side of one of the round rods 44. The fourth gear 46 is located on the top of the fifth gear 47 and meshes with the fifth gear 47. After the sixth motor 45 works, it drives the fourth gear 46 to rotate. At this time, the fourth gear 46 drives the fifth gear 47 to rotate.

[0056] In actual operation, when this device is used, first connect the power supply. When working, first fix the pipe fitting. Specifically, place the pipe fitting between two clamping plates 43. Then, the third cylinder 42 pushes the clamping plates 43. At this time, the two clamping plates 43 move towards each other until the two clamping plates 43 tightly clamp the pipe fitting, thus completing the fixing of the pipe fitting. On this basis, if the end of the pipe fitting facing upward is polished, the sixth motor 45 can be controlled to work and drive the fourth gear 46 to rotate. The fourth gear 46 drives the fifth gear 47 to rotate. The fifth gear 47 drives the connecting plate 41 to rotate. The connecting plate 41 drives the clamping plate 43 to rotate. Through the above connection relationship, it can be seen that the pipe fitting swings around the axis of the round rod 44 to adjust the end facing upward in different directions and polish it in sequence. Compared with manual adjustment and changing of the surface, it is more flexible.

[0057] In this device, a new polishing rod 393 can be inserted into a socket 398 on the outer side of one of the conveyor belts 396 for backup. During the insertion of the polishing rod 393, it will first contact the inclined surface on the fixing block 383, thereby pushing the two fixing blocks 383 outward. After the polishing rod 393 is inserted into the socket 398, under the elastic thrust of the second spring 385, it can drive the limiting plate 384 to move. The limiting plate 384 drives the fixing block 383 to move in the direction of the polishing rod 393, so that the two fixing blocks 383 can clamp the polishing rod 393, improving the stability of the polishing rod 393 when placed. The socket 398 on the other conveyor belt 396 is used to store the old polishing rod 393 after disassembly, so as to distinguish and store them, which is beneficial to the user for classified operation and processing.

[0058] During grinding, the first motor 391 works and drives the mounting rod 392 to rotate. The mounting rod 392 drives the rectangular plug frame 394 to rotate. The rectangular plug frame 394 drives the grinding rod 393 to rotate. When the grinding rod 393 contacts the outside of the pipe fitting, the outside of the pipe fitting port can be ground. When the grinding rod 393 is inserted into the inside of the port, it can contact the inner surface of the pipe fitting and be ground.

[0059] When the third motor 372 is working, it drives the threaded control rod 371 to rotate. The threaded control rod 371 drives the moving block 35 to move horizontally. The moving block 35 drives the frame plate 36 to move. According to the above connection relationship, the horizontal position of the grinding rod 393 can be adjusted. After the second motor 387 is working, it drives the first gear 388 to rotate. The first gear 388 drives the gear ring 386 to rotate. The gear ring 386 drives the ring plate 32 to rotate. The ring plate 32 drives the rectangular frame 34 to rotate. With the above adjustment steps for adjusting the horizontal position of the grinding rod 393, the grinding rod 393 can be made to revolve around the center point of the ring plate (32). During the revolution, the outer periphery of the pipe can be evenly ground. Based on the above adjustment steps, after the first cylinder 389 is working, it pushes and pulls the guide plate 33. The guide plate 33 can drive the ring seat 31 to move up and down. According to the above connection relationship, the grinding height can be adjusted to match different port heights, which improves the flexibility in the grinding process.

[0060] When the grinding rod 393 needs to be replaced, firstly, by controlling the rotation of the rectangular frame 34 as described above, the two ends of the rectangular frame 34 are respectively directed to the two conveyor belts 396. Then, after the second cylinder 374 operates, it pushes and pulls the movable plate 375. The movable plate 375 drives the rack 373 to move. After the rack 373 moves, it drives the third gear 376 to rotate. The third gear 376 drives the shaft 38 to rotate. The shaft 38 drives the mounting plate 37 to swing around the shaft 38 as the axis. The mounting plate 37 drives the mounting frame 39 to swing. This controls the mounting plate 37 to swing 90 degrees towards the conveyor belt 396 used to store the old grinding rod 393. At this time, the grinding rod 393... The end of the control block 35 is pointed to the socket 398 on the conveyor belt 396. Then, the above steps of controlling the movement of the moving block 35 are repeated. After the old grinding rod 393 is inserted into the socket 398 on the conveyor belt 396, the fourth motor 362 works and drives the bidirectional threaded rod 361 to rotate. The bidirectional threaded rod 361 drives the two threaded blocks 378 to move towards each other. The threaded blocks 378 drive the pressing rod 379 to move to press the trapezoidal block 381 and push the trapezoidal block 381 into the mounting rod 392. At this time, the control block 35 moves away from the socket 398, so that the rectangular plug frame 394 can be separated from the mounting rod 392 smoothly.

[0061] After the old polishing rod 393 is removed, repeat the above operation. After the mounting rod 392 is pointed to the new polishing rod 393 on another conveyor belt 396, control the mounting rod 392 to move towards the new polishing rod 393 until the mounting rod 392 is inserted into the rectangular insertion frame 394 on one side of the new polishing rod 393. At this time, under the elastic force of the first spring 382, ​​the trapezoidal locking block 381 passes through the slot, completing the locking of the rectangular insertion frame 394 and the mounting rod 392. After controlling the mounting rod 392 to move, the new polishing rod 393 can be pulled out directly for use. The replacement process is simple and convenient and does not require much manual intervention, which saves manpower.

[0062] When it is necessary to convey the grinding rod 393 on the conveyor belt 396, the fifth motor 363 works and drives the connected conveyor roller 397 to rotate. This conveyor roller 397 drives the external pulley 364 to rotate. This pulley 364 drives another pulley 364 to rotate through the belt. At this time, the conveyor rollers 397 connected to the pulleys 364 on the inner side of both conveyor belts 396 start to rotate. After the conveyor rollers 397 rotate, they drive the conveyor belt 396 to rotate. After the conveyor belt 396 rotates, it drives the socket 398 to move. In this way, new grinding rods 393 or old grinding rods 393 can be conveyed, which makes it convenient for the staff to replenish the new grinding rods 393 and remove the old grinding rods 393, ensuring that the replacement of grinding rods 393 can be carried out smoothly.

[0063] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
