Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamping equipment, in particular to an adjustable clamping claw assembly. Background Art
[0002] The chuck is a type of clamping device that clamps the workpiece to be processed by controlling the movement of the jaw assembly. However, there is an accumulated tolerance after each processing, and the workpieces installed on the chuck will be one front and one back, which cannot achieve symmetry. The accumulated error can be compensated by adjusting the rollers forward and backward to achieve symmetry on both sides.
[0003] The claw assembly in the prior art is as follows Figure 1 , 2 As shown, an eccentric structure is set on the rotating shaft of the roller on the eccentric structure rotating claw assembly. When in use, the knobs on both sides of the roller are turned to achieve fine adjustment, but the conventional adjustment range is only 0.5mm, which is not very effective. The adjustment of this eccentric structure is achieved according to the different distances from different positions on the periphery of the eccentric wheel to the center of the circle. The change in this distance is not linear, so the change in size during adjustment is not intuitive, and multiple adjustments are required, which is very inconvenient. Moreover, this eccentric structure is relatively complex. In order to ensure the accuracy of the claws, the eccentric structure needs to be kept in the corresponding position, so it is also very troublesome during maintenance and disassembly. Utility Model Content
[0004] In view of the above problems, the purpose of the utility model is to provide an adjustable clamping assembly which is more intuitive to adjust and convenient to assemble and disassemble.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: an adjustable claw assembly, comprising a claw frame, adjusting sliders are provided on both sides of the claw frame, and slider fixing holes are provided on the sides of the adjusting sliders, and the slider fixing holes are flat holes. The adjusting sliders are fixedly connected to the claw frame by slider fixing bolts at the slider fixing holes, and a roller is installed between the two adjusting sliders.
[0006] In the above technical solution, track grooves are provided on both sides of the clamping claw frame, and the adjusting slider is arranged in the track grooves and can move back and forth along the track grooves.
[0007] In the above technical solution, a guide boss is provided on the side of the fixing hole facing the track groove, and the guide boss is clamped in the track groove.
[0008] In the above technical solution, a limit platform is provided on the rear part of the clamping claw frame at the adjusting slide block, and an adjusting bolt is provided on the limit platform, and the adjusting bolt can push the adjusting slide block to move.
[0009] In the above technical solution, the front end of the adjusting slider is provided with a roller mounting hole and a roller fixing hole which are arranged perpendicular to each other, and the two ends of the roller are respectively inserted into the roller mounting holes of the adjusting slider on the corresponding side and fixed by roller fixing bolts in the roller fixing holes.
[0010] To sum up, the technical solution of the utility model has the following beneficial effects compared with the traditional technical means: the utility model changes the eccentric adjustment structure of the existing claw assembly into a slider type, and a flat hole is arranged on the slider. The roller can be adjusted by pushing the adjustment slider and fixing it. The adjustment distance is more intuitive and the structure is simple. It is simpler and more convenient to align during maintenance and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS
