[0021] See also Figure 1-3 The anti-vibration auxiliary component in this embodiment includes a push block 62 fixed on the opposite side of the two clamping plates 4, and the anti-vibration auxiliary component also includes a connecting block 61 fixed on the opposite side of the two push plates 2. A support plate 63 is fixed on the opposite end of the two push blocks 62. Two push rods 64 are hingedly connected to the opposite side of the two support plates 63. The other end of the push rod 64 is hingedly connected to an extrusion block 65. A first buffer spring 66 is fixed to the opposite side of the front and rear extrusion blocks 65. Two support blocks 67 are fixed to the opposite side of the left and right groups of extrusion blocks 65. The anti-vibration auxiliary component also includes a buffer structure arranged on the opposite side of the left and right groups of push rods 64 for secondary buffering performance.

[0022] The two connecting blocks 61 have shrinkage holes on opposite sides thereof. The push block 62 passes through the shrinkage holes to the inside of the connecting block 61 and is slidably connected thereto, so that the push block 62 can move into or out of the inside of the connecting block 61 through the shrinkage holes.

[0023] In addition, the support plate 63 is slidably connected to the interior of the connecting block 61, and the outer surface of the support plate 63 is in contact with the inner cavity wall of the connecting block 61, so that the support plate 63 can move smoothly in the inner cavity of the connecting block 61, so as to provide support for one end of the push block 62 located in the inner cavity of the connecting block 61.

[0024] In addition, two sliding grooves are provided on the upper and lower walls of the inner cavity of the connecting block 61, and the support block 67 is located inside the sliding groove and is slidably connected thereto, so that the support block 67 can move in the inner cavity of the connecting block 61, so that the two support blocks 67 in the same group can support the extrusion block 65, so that the extrusion block 65 can stably move in the inner cavity of the connecting block 61, thereby allowing the extrusion block 65 to accurately extrude the first buffer spring 66.

[0025] Moreover, the opposite ends of the front and rear groups of first buffer springs 66 are respectively fixed to the front and rear walls of the inner cavity of the two connecting blocks 61, so that the two ends of the first buffer spring 65 are respectively fixedly connected to the extrusion block 65 and the connecting block 61, so that the extrusion block 65 can extrude the first buffer spring 66.

[0026] See also Figure 3 The buffer structure in this embodiment includes an articulated rod 68 hingedly connected to the side opposite to the left and right groups of push rods 64, and the other end of the articulated rod 68 is hingedly connected to a shift block 69. The inner cavities of the two shift blocks 69 on the same side are slidably connected to an I-shaped rod 610, and the outer surface of the I-shaped rod 610 is sleeved with two second buffer springs 611.

[0027] Secondly, the two I-shaped rods 610 are respectively fixed to the opposite walls of the inner cavities of the two connecting blocks 61 so as to provide support for the moving block 69 and the second buffer spring 611 and limit the moving range of the moving block 69 in the inner cavity of the connecting block 61 .

[0028] In addition, circular holes are opened on opposite sides of the front and rear groups of shifting blocks 69, and the I-shaped rod 610 passes through the inner side of the circular hole and is slidably connected thereto, so that the shifting blocks 69 can slide on the outer surface of the I-shaped rod 610 through the circular hole.

[0029] The working principle of the above embodiment is:

[0030] When in use, when the two clamping plates 4 clamp and fix the workpiece, the output ends of the two electric push rods 1 push the two push plates 2 to move relative to each other, so that the two push plates 2 drive the two clamping plates 4 to move relative to each other through the left and right two sets of telescopic rods 3. When the two clamping plates 4 abut against the workpiece, the electric push rod 1 continues to push the push plate 2 to move, so that the push block 62 can gradually move to the inside of the connecting block 61, that is, the push block 62 can push the support plate 63 to move in the inner cavity of the connecting block 61, so that the support plate 63 can squeeze the two push rods 64 of the same group, so that the two push rods 64 of the same group can be pushed to gradually move from an inclined state to a horizontal state, so that the two push rods 64 of the same group can push the front and rear extrusion blocks 65 to move back to each other, so that the extrusion block 65 can squeeze the first buffer spring 66, so as to buffer the impact force of the clamping plate 4 on the workpiece;

[0031] Moreover, when the push rod 64 gradually moves from an inclined state to a horizontal state, the push rod 64 can drive the hinged rod 68 to move, so that the front and rear hinged rods 68 can drive the two shifting blocks 69 of the same group to move back to back on the outer surface of the I-shaped rod 610, so that the shifting blocks 69 can squeeze the second buffer spring 611, thereby further enhancing the shockproof property of the clamp, and when the workpiece is vibrated during processing, the vibration force can also be buffered.
