Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp with an anti-slip mechanism. Background Art

[0002] Fixture: A device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection, also known as a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture. The fixture is usually equipped with an anti-slip mechanism to improve the stability of the clamping. In order to clamp multiple workpieces at one time, multiple fixtures with anti-slip mechanisms are usually installed on a bracket. After the fixture with an anti-slip mechanism is installed, if it needs to be removed for maintenance or replacement, it often requires the use of tools, which is time-consuming and laborious. Therefore, a fixture with an anti-slip mechanism is proposed to facilitate the removal and subsequent installation of the fixture. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a clamp with an anti-slip mechanism.

[0004] The technical solution adopted by the utility model to solve its technical problems is a clamp with an anti-slip mechanism, comprising a bracket, a plurality of supports and a plurality of three-jaw chucks are arranged below the bracket, the top ends of the plurality of supports are connected to the bracket, a clamp is fixed to the bottom end of the clamp of each of the three-jaw chucks, a limiting block is integrally formed at the bottom end of each of the clamps, a first anti-slip pad is fixed to each of the clamps, two blocks are fixed to the top end of each of the three-jaw chucks, two slots adapted to the blocks are arranged at the bottom end of each of the supports, a cross bar is arranged in each of the supports, the end of each cross bar extends outside the support, a pressure block is fixed to the end of each cross bar, a spring is sleeved on each cross bar, a card block is fixed to the bottom end of each cross bar, and a slot adapted to the card block is opened on the side wall of each of the blocks.

[0005] By adopting the above technical scheme, the three jaws of the three-jaw chuck drive the three clamping jaws to move toward the workpiece, which is convenient for clamping the workpiece. The setting of the first anti-slip pad and the limit block can improve the stability of the workpiece. If the three-jaw chuck needs to be removed for maintenance or replacement together with the clamping jaws, it is only necessary to press the pressure block, which drives the cross bar to move, and the block moves with the cross bar. The end of the block is disengaged from the slot on the side wall of the block, and the three-jaw chuck can be removed for maintenance or replacement by moving it down. During installation, press the pressure block, place the block fixed on the top of the three-jaw chuck in the slot at the bottom of the support, and then release the pressure block. The spring pushes the pressure block to reset, and the end of the block is inserted into the slot on the side wall of the block, which is convenient for the installation of the three-jaw chuck without the aid of tools, saving time and effort.

[0006] Specifically, a connecting block is fixed to the end of each cross bar away from the pressing block.

[0007] Specifically, a second anti-slip pad is fixed to the side wall of each pressing block away from the cross bar.

[0008] By adopting the above technical solution, the provision of the second anti-slip pad is conducive to pressing the pressing block.

[0009] Specifically, the side wall of each of the first anti-slip pads is integrally formed with a plurality of anti-slip protrusions.

[0010] By adopting the above technical solution and setting the anti-slip protrusions, the stability of the workpiece can be improved.

[0011] Specifically, a connecting seat is fixed to the top of the bracket, and a plurality of screw holes are formed at the top of the connecting seat.

[0012] By adopting the above technical solution, during installation, the bolts are screwed into the screw holes at the top of the connecting seat, so that the connecting seat can be fixed in a suitable position conveniently.

[0013] Beneficial effects of the utility model:

[0014] (1) The utility model discloses a clamp with an anti-skid mechanism. The three jaws of the three-jaw chuck drive the three jaws to move toward the workpiece, which is convenient for clamping the workpiece. The first anti-skid pad, the limit block and the anti-skid protrusion are arranged to improve the stability of the workpiece.

[0015] (2) The clamp with an anti-slip mechanism described in the utility model can be removed for maintenance or replacement together with the three-jaw chuck and the clamping jaws by pressing the pressure block. The pressure block drives the cross bar to move, and the clamping block moves with the cross bar. The end of the clamping block disengages from the slot on the side wall of the block. The three-jaw chuck can be removed for maintenance or replacement by moving it downward. During installation, the pressure block is pressed, the block fixed on the top of the three-jaw chuck is placed in the slot at the bottom of the support, and the pressure block is released. The spring pushes the pressure block to return to its original position, and the end of the clamping block is inserted into the slot on the side wall of the block, which facilitates the installation of the three-jaw chuck without the aid of tools, saving time and effort.

The setting of the first anti-slip pad 6 and the limit block 8 can improve the stability of the workpiece. If the three-jaw chuck 4 needs to be removed for maintenance or replacement together with the clamping jaws 5, it is only necessary to press the pressure block 11, and the pressure block 11 drives the cross bar 10 to move, and the clamping block 13 moves with the cross bar 10. The end of the clamping block 13 is disengaged from the slot on the side wall of the block 9, and the three-jaw chuck 4 can be removed for maintenance or replacement by moving it down. During installation, the pressure block 11 is pressed, the block 9 fixed at the top of the three-jaw chuck 4 is placed in the slot at the bottom of the support 3, and then the pressure block 11 is released. The spring 12 pushes the pressure block 11 to reset, and the end of the clamping block 13 is inserted into the slot on the side wall of the block 9, which is convenient for the installation of the three-jaw chuck 4 without the aid of tools, saving time and effort.
