[0018] like Figures 1-5 As shown, the specific embodiment adopts the following technical solution: it includes a conveyor frame 1 and a housing 2. The housing 2 is fixedly installed on the conveyor frame 1. A vacuum cleaner 19 is fixedly installed on the upper part of the housing 2. The two vacuum cleaner heads of the vacuum cleaner 19 are respectively fixedly installed on the front and rear sides of the inner side wall of the housing 2. The vacuum cleaner 19 can clean the debris generated during the door panel polishing process to ensure a good working environment inside the housing 2. It also includes: The first support frame 3 is slidably mounted inside the outer shell 2 via a slide rail pair. An internal threaded cylinder 4 is fixedly mounted on the upper part of the first support frame 3. A first motor 5 is fixedly mounted on the upper part of the outer shell 2.

The second support frame 7 consists of two parts, which are respectively suspended inside the outer shell 2 on the front and rear sides below the first support frame 3. The first support frame 3 has two sliding grooves 8 at its bottom, each with a slider 9 slidably installed. Both the slider 9 and the second support frame 7 are fixedly equipped with drive boxes 10. Two bellows covers 18 are fixedly installed in the sliding grooves 8, and the bellows covers 18 are fixedly connected to the sliders 9. The bellows covers 18 can protect the sliding grooves 8 and prevent the debris generated during the door panel polishing process from falling into the sliding grooves 8 and affecting the sliding of the sliders 9. The outer shell 2 is provided with a width adaptation mechanism 11 connected to the second support frame 7. The two second support frames 7 are fixedly equipped with fixing frames 16 on the left and right sides of their opposite sidewalls. The fixing frames 16 are rotatably connected to the stabilizing wheels 17 through shafts and bearings. When the door panel moves into the outer shell 2 with the conveyor frame 1 for polishing, the stabilizing wheels 17 will move and abut against the side of the door panel to ensure the stability of the door panel during the polishing process. There are four rotating rods 12, which are respectively inserted into the opposite side walls of the upper and lower drive boxes 10 via bearings. Two rotating rods 13 are inserted into the opposite side walls of the front and rear drive boxes 10 via bearings. A grinding wheel 14 is fixedly sleeved at one end of the first rotating rod 12 and the second rotating rod 13 at the outer position of the drive box 10. The drive box 10 is provided with a synchronous drive mechanism 15 connected to the first rotating rod 12 and the second rotating rod 13. The width adaptation mechanism 11 includes: The second motor 11-1 is fixedly installed on the front side wall of the outer shell 2. A bidirectional lead screw 11-2 is rotatably installed inside the outer shell 2 through bearings, and the bidirectional lead screw 11-2 is rotatably installed on two second support frames 7 through threads. The output shaft of the second motor 11-1 is connected to the bidirectional lead screw 11-2. Four guide rods 11-3 are fixedly installed on the left and right sides of the side walls of the two second support frames 7 respectively. Guide cylinders 11-4 are fixedly installed on the left and right sides of the front and rear inner side walls of the outer shell 2. The guide rods 11-3 are movably inserted into the guide cylinders 11-4. The bidirectional screw 11-2 can be rotated by the second motor 11-1. The guide rods 11-3 and the guide cylinders 11-4 provide movement guidance for the second support frame 7, so as to realize the adjustment of the distance between the two second support frames 7 to adapt to door panels of different width specifications. The synchronous drive mechanism 15 includes: There are two drive rods 15-1, which are fixedly installed on the upper ends of the two lower rotating rods 12 respectively, and the upper end of the drive rod 15-1 is movably inserted into the upper rotating rod 12. The second drive rod 15-2 is fixedly installed at the rear end of the second rotating rod 13 at the lower front side, and the front end of the second rotating rod 13 at the lower rear side is fixedly installed with a drive cylinder 15-3. The rear end of the second drive rod 15-2 is movably inserted into the drive cylinder 15-3. The No. 3 motor 15-4 is fixedly mounted on the front side wall of the No. 2 support frame 7 on the front side, and the output shaft of the No. 3 motor 15-4 is connected to the No. 2 rotating rod 13 on the lower front side. The No. 1 rotating rod 12 and the No. 2 rotating rod 13 in the same drive box 10 are connected by bevel gear transmission.

[0019] When using this utility model, starting motor 5 drives threaded rod 6 to rotate, causing internal threaded cylinder 4 to move support frame 3 upwards. This allows adjustment of the distance between the upper and lower grinding wheels 14 according to the thickness specifications of the door panel. Then, motor 11-1 is started, driving bidirectional lead screw 11-2 to rotate. Guide rod 11-3 and guide cylinder 11-4 guide the movement of support frame 7, allowing the two support frames 7 to move synchronously in opposite directions. This adjusts the distance between the lower front and rear grinding wheels 14. The linkage between drive rod 15-1 and rotating rod 12 further facilitates the movement of the two support frames. The sliders 9 slide synchronously in opposite directions, thereby achieving synchronous adjustment of the distance between the front and rear grinding wheels 14 on the upper side. This allows for adjustment of the distance between the front and rear grinding wheels 14 according to the width specifications of the door panel. Then, the door panel can be transported into the outer casing 2 using the conveyor frame 1, and the third motor 15-4 is started. The third motor 15-4 drives the second rotating rod 13 on the lower front side to rotate. By utilizing the bevel gear pair, the first drive rod 15-1, and the second drive rod 15-2, the four first rotating rods 12 and the four second rotating rods 13 can rotate synchronously, so that the eight grinding wheels 14 rotate synchronously and achieve synchronous grinding of multiple corners of the door panel, thereby ensuring the grinding quality of the door panel.

[0020] Compared with the prior art, the beneficial effects of this utility model are: By cooperating with the internal threaded cylinder 4, motor 5, threaded rod 6, slider 9, drive box 10, width adaptation mechanism 11, support frame 3 and support frame 7, the position of multiple grinding wheels 14 can be adjusted according to the width and thickness specifications of the door panel, thus fully expanding the scope of application. Through the cooperation of the first rotating rod 12, the second rotating rod 13 and the synchronous drive mechanism 15, the synchronous rotation of multiple grinding wheels 14 can be achieved, so as to ensure the consistency of the grinding degree of the multiple grinding wheels 14 on each corner of the door panel and ensure the grinding quality. The accordion cover 18 can protect the slide rail 8 and prevent debris generated during the door panel polishing process from falling into the slide rail 8 and affecting the sliding of the slider 9; The vacuum cleaner 19 can clean up the debris generated during the door panel polishing process to ensure a good working environment inside the outer casing 2.

[0021] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
