[0002] An alloy based on aluminum with a certain amount of other alloying elements added is one of the light metal materials. During the processing of aluminum alloy products, they need to be clamped and fixed by clamps to prevent them from being subjected to force and rotation during processing.

[0003] The utility model patent with announcement number CN217434097U discloses a new type of anti-crushing clamp for aluminum alloy products. This patent improves the appearance of the product and greatly improves the appearance quality by adopting nylon locating pins and top seat holes to add nylon locating sleeves, and at the same time changes the top seat support surface to point support. However, during the implementation of this patent, when the nylon locating sleeve and the pressure head are moved and positioned on the outside of the aluminum alloy product, they are prone to sliding friction with the outside of the aluminum alloy product, which can easily crush and scratch the aluminum alloy product, making it difficult to move the pressure head, and thus difficult to replace the clamping position of the aluminum alloy product. Therefore, this utility model provides a replaceable anti-crushing clamp for aluminum alloy products to solve the above problems. Utility Model Content

[0022] like Figure 1-3 As shown, a bearing 23 is installed on the side of the U-shaped plate 16 away from the third electric cylinder 19, and a rotating rod 21 is installed inside the bearing 23, a clamping roller 18 is installed on the outside of the rotating rod 21, and a fixed socket 20 is evenly provided on the side of the clamping roller 18 close to the third electric cylinder 19, a rubber sleeve 22 is installed on the outside of the clamping roller 18, and a brush 17 is evenly installed on the inside of the U-shaped plate 16. When the clamping position of the aluminum alloy product is changed, the clamping roller 18 moves on the outside of the aluminum alloy product, and the rubber sleeve 22 contacts the aluminum alloy product, which can force the clamping roller 18 to rotate, thereby avoiding sliding friction between the clamping roller 18 and the aluminum alloy product, and debris on the outside of the aluminum alloy product adheres to the rubber sleeve 22. When the rubber sleeve 22 rotates to contact the brush 17, the debris on the outside of the rubber sleeve 22 can be scraped off by the brush 17, thereby avoiding the debris from scratching the aluminum alloy product.
