The first slider 5 is slidably installed in the corresponding first sliding groove 6. When the second screw rod 3 rotates, the first slider 5 can limit the first nut 4 to prevent the first nut 4 from rotating with the second screw rod 3, ensuring that the first nut 4 can only move along the second screw rod 3. A cross plate 7 is installed on the first slider 5. The second dovetail chute 8 is provided on both sides of 7, and the second dovetail slider 9 is slidably installed in the second dovetail chute 8. The second dovetail slider 9 is connected to the corresponding second dovetail chute 8 by a first spring 10. One end of the first spring 10 is fixedly connected to one side of the second dovetail slider 9, and the other end of the first spring 10 is fixedly connected to the inner wall of the second dovetail chute 8. When the aluminum alloy door and window are clamped, the first spring 10 is in a compressed state. The second dovetail slider 9 is fixedly installed with a clamping plate 11. The side of the clamping plate 11 close to each other is an inclined surface. The height of the clamping plate 11 is lower than the thickness of the aluminum alloy door and window, which can ensure that the clamping plate 11 will not affect the polishing of the aluminum alloy door and window when the aluminum alloy door and window are polished. The utility model has a simple structure and an ingenious design. It can clamp the inner and outer sides of the aluminum alloy door and window at the same time, prevent the clamping force from being too large, causing the door and window to sag inward, and at the same time ensure the stability of the aluminum alloy door and window when clamping. It is simple to operate and can meet actual needs. When using the present invention, first adjust the distance between the two horizontal plates 7 according to the size of the door and window to be polished, rotate the second screw rod 3, and the second screw rod 3 drives the first nut 4 to move along the second screw rod 3, and the first nut 4 drives the second dovetail slider 9 and the horizontal plate 7 to move, and adjust the distance between the two horizontal plates 7. When the two horizontal plates 7 are adjusted to the appropriate position, stop rotating the second screw rod 3. At this time, align the two ends of the aluminum alloy door and window with the middle of the plywood 11 on both sides, and put the aluminum alloy door and window down. The aluminum alloy door and window gradually come into contact with the inclined surface of the plywood 11. As the aluminum alloy door and window moves downward, the plywood 11 gradually moves to both sides of the corresponding frame of the aluminum alloy door and window, and the first spring 10 is stretched. When the aluminum alloy door and window is completely placed on the horizontal plate 7, the plywood 11 can clamp the inside and outside of the aluminum alloy door and window. At this time, it can be polished using the polishing device.

[0017] Specifically, as shown in the figure, the workbench 1 described in this embodiment is provided with a grinding device, which can process aluminum alloy doors and windows. The grinding device includes a movable plate 20, on which a grinding roller 23 is rotatably installed. A first strip groove 25 is provided at the bottom of the movable plate 20, and support shafts 26 are fixedly installed at both ends of the grinding roller 23. The support shaft 26 is rotatably installed in the first strip groove 25 through a bearing. The bottom of the grinding roller 23 is located outside the first strip groove 25.
