The adjustment block is located on the side of the clamping block away from the clamping surface and is detachably connected to the clamping block. The reference block is located outside the adjustment block and is connected to the slider. The adjustment block abuts against the reference block.
[0006] Based on the product model and specifications, select the appropriate adjusting block and adjust the relative positions between the adjusting block, the reference block, and the clamping block. Finally, lock them in place using the locking unit to achieve a stable, reliable, and precise fit between the clamping block and the slider, thus achieving high-precision and reliable clamping of the product to be held. After prolonged use and wear, the fixture can be readjusted using the adjusting components, offering excellent maintenance convenience.

Two sliders 3 are slidably disposed on the chuck base 1, and the two sliders 3 are positioned opposite each other. The clamping drive 2 is used to drive the two sliders 3 to move relative to each other.
[0019] Specifically, such as Figure 4 As shown, the clamping drive component 2 includes a wedge seat 21 and a power unit. The power unit drives the wedge seat 21 to move along a sliding direction perpendicular to the slider 3. The wedge seat 21 has two opposing wedge-shaped grooves 22, which are inclined relative to the direction of movement of the wedge seat 21. The slider 3 has a wedge-shaped block, and the slider 3 is connected to the wedge seat 21 through the wedge-shaped block and the wedge-shaped groove. Through the cooperation of the wedge-shaped grooves 22 and the wedge-shaped block, the longitudinal movement of the wedge seat 21 can be converted into the lateral movement of the slider 3, ultimately achieving the clamping of the product.
[0020] like Figures 1-3 As shown, it also includes clamping blocks 5 that correspond one-to-one with sliders 3. A locking unit is provided between the clamping blocks 5 and sliders 3.
