[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a clamping tool for processing the side wall of a shaft part includes a mounting seat 1, on which are arranged:

[0029] A lower fixture 2 symmetrically fixedly arranged;

[0030] An adapter seat 3 and a connecting rod 4 are symmetrically arranged coaxially with respect to the center of the lower clamp 2;

[0031] The upper clamp 5 is arranged in parallel with the lower clamp 2 , and the first end of the upper clamp 5 is rotatably assembled with the connecting rod 4 , and the second end is provided with a U-shaped groove 51 , which is clamped with a bolt locking member 6 rotatably arranged on the adapter 3 .

[0032] Furthermore, the adjacent surfaces of the lower clamp 2 and the upper clamp 5 are provided with grooves of inverted isosceles trapezoidal structure;

[0033] First pads 7 arranged in a linear array are respectively provided on the two waists of the lower clamp 2;

[0034] Second cushion blocks 8 are respectively arranged on the two sides of the upper clamp 5 .

[0035] Secondly, the opposite side edges of the two first cushion blocks 7 located on the same waist and the side edges of the second cushion block 8 are in the same water surface.

[0036] Specifically, the first cushion block 7 and the second cushion block 8 in the above embodiment are hard rubber blocks.

[0037] In the above technology, the shaft is placed on the lower clamp 2, and then the upper clamp 5 is flipped over and the position of the nut on the bolt locking piece 6 is changed so that the U-shaped groove 51 of the upper clamp 5 is inserted into the bolt locking piece 6. The nut is then rotated and pressed down so that the upper clamp 5 is flipped and pressed down with one end of the connecting rod 4 as the hinge point to clamp the shaft.

[0038] As an embodiment provided by the present invention, two second pads 8 on the same upper clamp 5 are respectively provided with reinforcing ribs 81 arranged in a linear array.

[0039] Furthermore, the reinforcing ribs 81 on the two second cushion blocks 8 have opposite inclination directions, and the width of the reinforcing ribs 81 increases gradually from the opposite side to the adjacent side.

[0040] Specifically, good left-hand and right-hand damping effects are provided.

[0041] As another embodiment provided by the utility model, a derivation part 9 is movably provided in the groove and slides vertically, and an arrow part 91 is provided at the end of the derivation part 9 and slides in the inner cavity groove 21 of the lower clamp 2;

[0042] The structure also includes a top spring 10 for forcing the arrow portion 91 to be located at the top end of the cavity 21 arranged vertically.

[0043] Secondly, a wedge block 92 is slidably provided in the lower clamp 2 and is slidably matched with the side wall of the arrow portion 91; and a base plate 93 is slidably provided in the lower clamp 2, and a pulling rod 94 is slidably provided on the base plate 93 at one end of which is rotatably connected to the lower clamp 2, and the wedge block 92 is rotatably provided with a push rod 95 that rotates on one end of the pulling rod 94 close to the base plate 93.

[0044] Furthermore, it also includes a double-linked connecting rod group 96 for keeping the first cushion block 7 and the base plate 93 synchronized.

[0045] Specifically, when the upper clamp 5 is pressed downward so that the negative pressure of the shaft causes the derivation part 9 to move downward, the arrow part 91 moves downward, and then the two wedge blocks 92 separate to both sides, thereby pushing the base plate 93 upward and pushing the first pad 7 to contact the surface of the shaft, thereby achieving the fixation of multiple contact points, thereby ensuring the fixing effect and achieving a good anti-rotation effect.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
