[0026] Example 1, as Figure 1 and Figure 2 shown, a clamping device for automotive plastic parts includes a base 1. Support legs 2 are fixedly connected to the four corners at the lower end of the base 1. A partition board 3 is fixedly connected to the inner surface of the base 1. A clamping and rotating assembly 4 is arranged at the upper end of the base 1. A cleaning assembly 5 is arranged on the inner surface of the base 1.

[0027] In the process of implementing this example, the automotive plastic part is placed in the clamping and rotating assembly 4, and the base 1 is connected to an external power supply. When it is necessary to perform grinding operations on the automotive plastic part, the clamping and rotating assembly 4 can drive the automotive plastic part to rotate and flip, facilitating the staff to process it. Subsequently, the debris generated during the grinding process can also be collected and cleaned by the cleaning assembly 5.

[0028] Specifically, in order to clamp, rotate and flip the plastic part, refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 . In this example, the clamping and rotating assembly 4 includes a circular cover 41 fixedly connected to the lower part of the inner surface of the base 1. A rotating mechanism 42 is arranged on the inner surface of the partition board 3. A clamping mechanism 43 is arranged at the upper end of the rotating mechanism 42. A flipping mechanism 44 is arranged on the inner surface of the clamping mechanism 43.

[0029] Furthermore, refer to Figure 3 and Figure 4, in this embodiment, the rotating mechanism 42 includes a fixed rod 421 fixedly connected to the lower part of the inner surface of the base 1. The upper end of the circular cover 41 is fixedly connected to a dual-axis motor 422. The upper and lower ends of the dual-axis motor 422 are symmetrically fixedly connected to rotating rods 423 through couplings. The outer surface of the fixed rod 421 and the inner surface of the partition 3 are jointly rotatably connected to a sleeve rod 425. The outer surface of the sleeve rod 425 and the outer surface of the upper rotating rod 423 are jointly fixedly connected to a first gear set 424. The upper end of the fixed rod 421 is fixedly connected to a circular plate 427, the upper end of the sleeve rod 425 is fixedly connected to a circular ring 426, and the inner surface of the fixed rod 421 is rotatably connected to a rotating ring 428.

[0030] Further, referring to Figure 3 and Figure 5 , in this embodiment, the clamping mechanism 43 includes a first cylinder 431 and an electric cylinder 432 fixedly connected to the lower part of the inner surface of the base 1. The left end of the electric cylinder 432 is fixedly connected to a first piston rod 433 slidably connected to the inner surface of the first cylinder 431. The upper end of the circular ring 426 is symmetrically fixedly connected to fixing plates 434 on the left and right. The inner surfaces of the two fixing plates 434 are both fixedly connected to second cylinders 435. The inner surfaces of the two second cylinders 435 are both slidably connected to second piston rods 436. The inner surface of the first cylinder 431 is connected to the inner surface of the fixed rod 421 through a pipeline. The inner surfaces of the two second cylinders 435 both penetrate and extend to the inner surface of the rotating ring 428 and are fixedly connected to connecting pipes 437. The two connecting pipes 437 are rotatably connected to the second cylinders 435. The mutually approaching ends of the two second piston rods 436 are both fixedly connected to clamping members 438.

[0031] During the implementation process, by starting the electric cylinder 432, the electric cylinder 432 is made to push the first piston rod 433 to slide on the inner surface of the first cylinder 431, so that the hydraulic oil in the inner cavity of the first cylinder 431 enters the inner cavity of the fixed rod 421 through the pipeline, and then enters the space formed by the rotating ring 428 and the fixed rod 421, and will flow into the inner cavities of the two second cylinders 435 through the connecting pipes 437, thereby pushing the clamping members 438 on the two second piston rods 436 to approach each other towards the middle. When adjusted to an appropriate distance, at this time, the plastic part is fixed by the clamping members 438. By transmitting pressure through the hydraulic oil, the clamping force is more evenly distributed, reducing damage to the surface of the plastic part, thereby improving the processing accuracy and surface quality, and enhancing the production efficiency and product quality of automotive plastic parts.

[0032] Secondly, when the position of the clamping part 438 needs to be rotated, the upper output end of the dual-axis motor 422 is started to drive the rotating rod 423 located at the upper part to rotate through the coupling, and under the transmission action of the gear set 424, the ring 426 on the sleeve rod 425 is driven to rotate, thereby realizing the rotation of the clamping part 438, which is convenient for changing the position during the processing. The adjustable rotation facilitates all-round operation of plastic parts during the grinding process, avoids the processing blind spots caused by the traditional fixed clamping method, improves the processing efficiency and quality, and increases the flexibility and adaptability of the processing process. It can better meet the needs of complex shapes and multi-angle grinding of automotive plastic parts.

[0033] The clamping member 438 mentioned above is a mature clamping technology means and equipment in the prior art. In this solution, it only needs to be able to fix automobile plastic parts, and its internal structure, principle and connection method will not be elaborated.

[0034] For further information, see Figure 3 and Figure 6 In this embodiment, the flipping mechanism 44 includes a round block 441 fixedly connected to the two cylinders 435, the inner surfaces of the two fixed plates 434 are connected to the connecting rod 442 for common rotation, the outer surface of the round block 441 on the same side and the outer surface of the connecting rod 442 are fixedly connected to the gear set 443, and the right end of the connecting rod 442 is fixedly connected to the servo motor 444 fixedly connected to the outer surface of the ring 426.

[0035] During the implementation process, when it is necessary to flip the clamped automobile plastic parts, the output end of the servo motor 444 is started to drive the connecting rod 442 to rotate through the coupling, and then the two sets of gear sets 443 are used to drive the two cylinders 435 to rotate on the inner surface of the fixed plate 434, thereby realizing the flipping operation of the automobile plastic parts. This can enable the automobile plastic parts to be easily converted to multiple angles, avoid single-angle grinding, improve grinding efficiency, and accurately and evenly grind various parts of the plastic parts to ensure processing quality and meet the multi-angle processing requirements of complex plastic parts.

[0036] The gear set 1 424 and the gear set 2 443 mentioned above are both composed of two gears meshing with each other.

[0037] The dual-axis motor 422 and servo motor 444 mentioned above are both mature driving technology means and equipment in the existing technology, and their internal structures, principles and connection methods are no longer described in this solution.

[0038] Embodiment 2: Based on the embodiment 1, this embodiment further includes a cleaning component 5 for collecting debris during the polishing process of automobile plastic parts, thereby achieving the purpose of collecting debris during the polishing process of automobile plastic parts.

[0039] Specifically, in order to collect the debris generated during the grinding process of automotive plastic parts, refer to Figure 3 , Figure 7 and Figure 8 . In this embodiment, the cleaning assembly 5 includes a conical block 51 fixedly connected to the upper end of the circular plate 427. A collecting mechanism 52 is provided at the upper end of the partition plate 3, and a blowing mechanism 53 is arranged in the inner cavity of the circular cover 41.

[0040] Furthermore, refer to Figure 3 and Figure 7 . In this embodiment, the collecting mechanism 52 includes a conical frame 521 fixedly connected to the upper end of the partition plate 3. Two scraping plates 522 are fixedly connected to the outer surface of the sleeve rod 425. The lower part of the inner surface of the conical frame 521 penetrates and extends to the front end of the base 1 and is fixedly connected with a communicating pipe 523.

[0041] During the implementation process, the debris generated during the grinding of the plastic parts will fall on the conical block 51 under the action of gravity. Since the outer surface of the conical block 51 is inclined, it will fall into the conical frame 521 through the conical block 51. At the same time, when the sleeve rod 425 rotates, it will drive the scraping plate 522 to rotate, thereby scraping the inner surface of the conical frame 521, and discharging the generated debris through the communicating pipe 523. It effectively collects and discharges the debris generated during the grinding process, prevents the debris from accumulating in the processing area, avoids scratching or damaging the surface of the plastic parts, and at the same time keeps the working environment clean and improves the processing quality.

[0042] Furthermore, refer to Figure 3 and Figure 8 . In this embodiment, the blowing mechanism 53 includes a fan blade 531 fixedly connected to the outer surface of the lower rotating rod 423. A circular groove ring 532 is fixedly connected to the upper end of the base 1. A rotating plate 533 is rotatably connected to the inner surface of the circular groove ring 532. The inner surface of the circular groove ring 532 is connected to the inner surface of the circular cover 41 through a pipeline. The lower end of the rotating plate 533 penetrates and extends to the right end of the left fixing plate 434 and is fixedly connected with an air outlet pipe 534. The upper part of the inner surface of the circular cover 41 penetrates and extends to the front end of the base 1 and is fixedly connected with an air inlet pipe 535.

[0043] During the implementation process, before the plastic parts are processed and ground or when observation is required during grinding, the fan blade 531 on the lower rotating rod 423 driven by the output end of the lower end of the double-shaft motor 422 through a coupling can be rotated, and the external air can be inhaled through the air inlet pipe 535, enter the space formed by the circular groove ring 532 and the rotating plate 533 through the pipeline, and be blown out through the air outlet pipe 534 to perform a blowing operation on the plastic parts. It can effectively disperse the heat before or when observation is required during the grinding of automotive plastic parts, avoid the plastic parts from deforming or being damaged due to local overheating, and at the same time blow away the debris and dust on the surface, improve the processing accuracy and quality, keep the working environment clean, and improve the processing efficiency.

[0044] Workflow: When in use, the automotive plastic part is clamped and fixed by the clamping mechanism 43. Subsequently, the automotive plastic part can be rotated and flipped by the rotating mechanism 42 and the flipping mechanism 44 to achieve a full rotation of the plastic part. And during the grinding operation, the generated debris can be cleaned and collected by the collection mechanism 52 and the blowing mechanism 53.
