Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile processing, and specifically relates to aluminum profile surface polishing equipment and a matching clamping tool. Background Art

[0002] During the production process of aluminum profiles, the surface of the product needs to be polished or brushed, and polishing equipment is usually used for the surface polishing of aluminum profiles. However, the existing polishing equipment technology is still imperfect, and there are still technical problems that need to be further improved. For example, the aluminum profile surface polishing equipment disclosed in patent document CN114505777A includes a lifting support block 64, a clamping support frame 65, an electric push rod 66 and a clamping column 67. The clamping support frame 65 is rotatably connected to the lifting support block 64, and two electric push rods 66 are provided. The two electric push rods 66 are respectively fixed to the two ends of the clamping support frame 65, and two clamping columns 67 are provided. The two clamping columns 67 are respectively fixed to the two electric push rods 66. First, the two clamping columns 67 are driven by two electric push rods 66 to clamp the aluminum profile to be polished. The use of two electric push rods causes a certain waste of equipment manufacturing costs and energy consumption costs, and the synchronization of the two clamping columns is not easy to ensure; on the other hand, the entire clamping tool of the polishing equipment and its storage rack are only connected by the positioning telescopic rod 62 and the supporting slider 63, and the reliability of the connection is also lacking, which is not conducive to the stability of clamping the aluminum profile workpiece. Therefore, it is necessary to further improve and perfect the existing aluminum profile surface polishing equipment and its clamping tool. Utility Model Content
