[0023] A screw rod 9, the screw rod 9 passes through one side of the interior of the clamp body 5, and a handle 10 is provided at one end of the screw rod 9;

[0024] A clamping head 7, the clamping head 7 is arranged on a side of the screw rod 9 away from the handle 10, and the buffer mechanism 6 is arranged on a side of the clamp body 5 away from the clamping head 7;

[0025] By turning the handle 10, the screw is rotated 9, driving the clamping head 7 to move, and the workpiece is clamped and fixed between the clamping head 7 and the buffer mechanism 6, which is convenient for subsequent grinding processing;

[0026] The buffer mechanism 6 includes a groove 601, a buffer spring 602, a pressure piece 603 and a contact plate 604. The pressure piece 603 is evenly arranged inside the groove 601 through the buffer spring 602, and the contact plate 604 is arranged at one end of the pressure piece 603.

[0027] When the workpiece is clamped, the abutment plate 604 is squeezed, causing it to compress the buffer spring 602 in the groove 601, so that a margin is left when the workpiece is clamped, and it is not easy to cause rigid squeezing on the workpiece, and it is not easy to damage the workpiece;

[0028] Limiting grooves are provided on both sides of the groove 601, and limiting blocks are provided on both sides of one end of the pressure-bearing member 603 to limit the range of motion of the buffer spring 602;

[0029] One side of the stand 2 is rotatably connected to a cylinder 4 via a rotating shaft, and the output end of the cylinder 4 is rotatably connected to the bottom of the clamp body 5 via a telescopic rod;

[0030] The cylinder 4 can push the clamp body 5 to rotate around the stand 2 through the telescopic rod, and adjust the inclination angle of the clamp body 5, so that the inclination angle of the clamped workpiece can be adjusted, and the inclined surface of the workpiece can be polished to meet different polishing requirements;

[0031] The end of the screw rod 9 close to the clamping head 7 is provided with a disassembly mechanism 8, which includes a mounting sleeve 801 and a limiting hole 806. The limiting holes 806 are provided on both sides of the mounting sleeve 801.

[0032] The disassembly mechanism 8 further includes a mounting block 804, a receiving groove 803, a return spring 802 and a limit bead 805. The mounting block 804 is arranged at one end of the clamping head 7 close to the mounting sleeve 801, and the receiving grooves 803 are provided on both sides of the mounting block 804. The inside of the receiving groove 803 is evenly provided with limit beads 805 through the return spring 802, and the limit beads 805 extend to the outside of the limit hole 806.

[0033] According to the type of workpiece to be clamped, a suitable clamping head 7 is selected, and the mounting block 804 at one end thereof is inserted into the mounting sleeve 801. When the limiting bead 805 passes through the limiting hole 806, it pops out under the action of the return spring 802 and is clamped outside the limiting hole 806, so that the clamping head 7 and the mounting sleeve 801 are fixed and clamped, which facilitates the rapid installation and removal of the clamping head 7 according to different workpieces, thereby improving the grinding efficiency;

[0034] A guide block 11 is disposed at the bottom end of the installation sleeve 801 , and a guide groove corresponding to the guide block 11 is provided at the central position of the bottom of the clamp body 5 to guide and limit the installation sleeve 801 and the clamping head 7 .

[0035] Working principle: When the embodiment of the present application is in use, the base plate 1 is fixed on the surface grinder, and the screw rod 9 is rotated by turning the handle 10 to drive the clamping head 7 to move, so that the workpiece is clamped and fixed between the clamping head 7 and the buffer mechanism 6, which is beneficial to the subsequent grinding process. When the workpiece is clamped, the contact plate 604 is squeezed, causing it to compress the buffer spring 602 in the groove 601, so that a margin is left when the workpiece is clamped, and it is not easy to cause rigid squeezing of the workpiece, and it is not easy to clamp the workpiece. At the same time, the cylinder 4 can push the clamp body 5 to rotate around the stand 2 through the telescopic rod, and adjust the inclination angle of the clamp body 5 so that the clamped workpiece can be adjusted to adjust the inclination angle, and the inclined surface of the workpiece can be grinded to meet different grinding requirements. If the clamping head 7 needs to be replaced, the limit bead 805 can be pressed to squeeze the reset spring 802 and store it in the storage groove 803, and then the mounting block 804 can be pulled out and separated from the mounting sleeve 801, which is convenient for the rapid installation and disassembly of the clamping head 7 according to the different workpieces, thereby improving the grinding efficiency.
