The fixed clamping plates are fixed to the upper surface of the worktable, and the lower end of the movable clamping plates extends into the interior of the worktable. The number of fixed clamping plates and movable clamping plates is equal, and each fixed clamping plate and the movable clamping plate adjacent to it on one side form a group.

[0007] As a further embodiment of this utility model: a connecting block is fixedly connected between adjacent movable clamping plates, the connecting block being located inside the worktable, a handwheel being provided on the front side of the worktable, a connecting shaft being fixedly connected to the side surface of the handwheel near the worktable, the connecting shaft extending into the interior of the worktable and being fixedly connected to a bearing, and the outer ring of the bearing being fixedly connected to the surface of the movable clamping plate closest to the front side, a threaded fitting being fixedly sleeved on the surface of the connecting shaft, and the threaded fitting being threadedly connected to the inner wall of the worktable, a spring being sleeved on the surface of the connecting shaft, the two ends of the spring respectively abutting against the side surface of the threaded fitting and the interior of the worktable.

[0008] As a further improvement of this utility model, the opposing surfaces of the fixed clamping plate and the movable clamping plate in the same group are both fixedly provided with a rubber layer.

[0009] As a further embodiment of this utility model: the number of polishing wheels is one more than the number of fixed clamps, and the gap between adjacent polishing wheels coincides with the gap between the fixed clamps and the movable clamps in the same group.

[0017] Please see Figures 1-3In this embodiment of the present invention, a polishing fixture for automotive window frame trim includes a worktable 1. A movable track 2 is fixedly connected to the front and rear edges of the upper surface of the worktable 1. A movable frame 4 is slidably sleeved on the surface of the movable track 2. A polishing motor 5 is fixedly installed on the rear surface of the movable frame 4. An extension shaft 14 is fixedly connected to the drive end of the polishing motor 5. Polishing wheels 15 are fixedly connected at equal intervals on the surface of the extension shaft 14. A clamping mechanism is provided between the movable tracks 2.

[0018] Preferably, the clamping mechanism includes fixed clamping plates 6 and movable clamping plates 7 arranged at equal intervals, and the fixed clamping plates 6 and movable clamping plates 7 are arranged alternately. The fixed clamping plates 6 are fixed to the upper surface of the workbench 1, and the lower end of the movable clamping plates 7 extends into the interior of the workbench 1. The number of fixed clamping plates 6 and movable clamping plates 7 is equal, and each fixed clamping plate 6 and the movable clamping plate 7 adjacent to one side form a group.

[0019] Preferably, a connecting block 10 is fixedly connected between adjacent movable clamping plates 7. The connecting block 10 is located inside the worktable 1. A handwheel 8 is provided on the front side of the worktable 1. A connecting shaft 11 is fixedly connected to the side surface of the handwheel 8 near the worktable 1. The connecting shaft 11 extends into the worktable 1 and is fixedly connected to a bearing. The outer ring of the bearing is fixedly connected to the surface of the movable clamping plate 7 closest to the front. A threaded fitting 12 is fixedly sleeved on the surface of the connecting shaft 11. The threaded fitting 12 is threadedly connected to the inner wall of the worktable 1. A spring 13 is sleeved on the surface of the connecting shaft 11. The two ends of the spring 13 abut against the side surface of the threaded fitting 12 and the interior of the worktable 1, respectively.

[0020] Preferably, the opposite surfaces of the fixed clamping plate 6 and the movable clamping plate 7 in the same group are both fixedly provided with a rubber layer 9.

[0021] Preferably, the number of polishing wheels 15 is one more than the number of fixed clamps 6, and the gap between adjacent polishing wheels 15 coincides with the gap between the fixed clamps 6 and the movable clamps 7 in the same group.

[0022] Preferably, a rack 3 is fixedly connected to the upper surface of the moving track 2, and a drive shaft 18 is rotatably arranged inside the moving frame 4. A gear 19 is fixedly connected to the surface of the drive shaft 18. There are two gears 19, which mesh with two racks 3 respectively. A dual-axis motor 16 is fixedly installed inside the moving frame 4. A drive belt 17 is wound between the two drive ends of the dual-axis motor 16 and one of the gears 19 respectively.

[0023] The working principle of this utility model is as follows: When polishing automotive window frame trim, the window frame trim is first placed between each set of fixed clamping plates 6 and movable clamping plates 7. By rotating the handwheel 8, the movable clamping plate 7 can be pushed towards the fixed clamping plate 6 due to the threaded connection between the threaded assembly 12 and the inner wall of the worktable 1, until each window frame trim is clamped and fixed by the fixed clamping plate 6 and the movable clamping plate 7. Under the action of the rubber layer 9, the window frame trim is prevented from being worn and deformed by clamping. The surface of the connecting shaft 11 is also fitted with a spring 13. When the handwheel 8 is rotated to move the movable clamping plate 7, the spring 13 forms a reverse thrust on the threaded assembly 12, which can prevent the fixed clamping plate from being damaged due to vibration during the subsequent polishing process. The window frame trim between the fixed clamp 6 and the movable clamp 7 is loose, affecting the polishing effect. During polishing, the polishing motor 5 is turned on to make the polishing wheel 15 rotate. The two sides of the polishing wheel 15 are used to polish the two sides of the window frame trim. At the same time, the dual-axis motor 16 is turned on, and the transmission belt 17 drives the gear 19 to rotate on the surface of the rack 3, thereby controlling the movement of the moving frame 4 to polish the window frame trim. After one side of the window frame trim is polished, the moving frame 4 can be controlled to reset. The handwheel 8 is turned in the opposite direction to release the window frame trim clamped between the fixed clamp 6 and the movable clamp 7. Then the direction of the window frame trim is adjusted, it is clamped and fixed again, and then polished.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
