Description

Technical Field

[0001] The utility model relates to a field, in particular to a hydraulic clamp. Background Art

[0002] Hydraulic clamps use hydraulic components instead of mechanical parts. The clamps are used to fix the materials or parts to be processed to ensure that they will not move or shift during the processing process, thereby preventing the shift of the objects to be processed from affecting the precision and accuracy of the processing operation. The table legs in furniture also need to be clamped and polished by hydraulic clamps during production.

[0003] At present, the main method is to place the table legs after production between two sets of clamps on the hydraulic clamp, and drive the clamp to clamp and fix them. Since the table legs usually have square or round shapes, in order to facilitate the clamping of the table legs, two square or round clamps that are compatible with them are usually set to clamp them separately. In the processing process, different clamp heads need to be frequently replaced according to the table legs, which makes the processing process more cumbersome and time-consuming. Secondly, during the grinding process, the table legs need to be turned over frequently, and the clamps need to be manually loosened and fixed, which makes the labor intensity of the staff higher. In view of the shortcomings of the existing technology, we propose a hydraulic clamp to solve the above problems. Utility Model Content

[0006] Preferably, a square hole is opened on the top of the clamp platform.

[0007] Preferably, a connecting block is fixedly connected to the bottom of the movable plate, and the connecting block slides inside the square hole.

[0008] Preferably, a transverse plate is fixedly connected to the bottom of the connecting block.

[0009] Preferably, the bottom of the clamp platform is fixedly connected to a bottom plate, hydraulic rods are provided on both sides of the bottom plate, and ends of the hydraulic rods are fixedly connected to the cross plate.
