However, these clamping devices are mostly used to clamp some bars with smaller diameters. When the diameter of the bar is larger, the mechanical clamps in the clamping device are limited by the range of movement and it is difficult to clamp the bar. Even if the bar is barely clamped, the clamping stability is not good. This problem needs to be improved urgently. Utility Model Content

The power mechanism 5 is arranged on the frame 1 and drives the first clamping plate 2 and the second clamping plate 3 to move toward or away from each other in the vertical direction through the linkage mechanism 4, so as to clamp and fix the large diameter bar. Figure 3 The linkage mechanism 4 includes a linkage gear 41, a first rack 42 and a second rack 43. The first rack 42 and the second rack 43 are respectively meshed with the opposite sides of the linkage gear 41 and are parallel to each other.

There is a space between the first clamping plate 2 and the second clamping plate 3 for accommodating the rod.

[0036] When it is necessary to clamp and fix the large diameter rod, the power mechanism 5 drives the linkage gear 41 to rotate, so that the first rack 42 and the second rack 43 respectively drive the first clamping plate 2 and the second clamping plate 3 to move away from each other, and the rod penetrates into the position between the first clamping plate 2 and the second clamping plate 3, and then the power mechanism 5 drives the linkage gear 41 to rotate in the opposite direction, so that the first rack 42 and the second rack 43 respectively drive the first clamping plate 2 and the second clamping plate 3 to move towards each other, and the first clamping plate 2 and the second clamping plate 3 cooperate to clamp and fix the large diameter rod.

The two second limiting plates 451 are both vertically fixedly arranged on the frame 1, and a second channel for the movement of the second rack 43 is formed between the two second limiting plates 451. The first limiting plates 441 and the second limiting plates 451 are arranged in parallel. The linkage gear 41 rotates to drive the first rack 42 and the second rack 43 to move in the vertical direction toward or away from each other.

[0039] Reference Figure 3 and Figure 4 The top of the first clamping plate 2 is fixedly connected with a first connecting plate 6 by bolts. The first connecting plate 6 is arranged horizontally. The other end of the first connecting plate 6 is fixedly connected to the top of the first rack 42 by bolts, so that the vertical up and down movement of the first rack 42 drives the vertical up and down movement of the first clamping plate 2. In addition, the first connecting plate 6 is fixedly provided with a first angle fixing plate 8 by bolts. The first angle fixing plate 8 is arranged in an L shape. One corner edge of the first angle fixing plate 8 is fixedly connected to the lower plate surface of the first connecting plate 6, and the other corner edge of the first angle fixing plate 8 is fixedly connected to the side wall of the first rack 42, so as to strengthen the structural strength of the connection between the first clamping plate 2 and the first rack 42, thereby facilitating the stability of the first clamping plate 2 when moving.

[0040] Reference Figure 3 and Figure 4The bottom of the second clamping plate 3 is fixedly connected to the second connecting plate 7 by bolts. The second connecting plate 7 is also arranged horizontally. The other end of the second connecting plate 7 is fixedly connected to the bottom of the second rack 43 by bolts, so that the vertical up and down movement of the second rack 43 drives the second clamping plate 3 to move vertically up and down. Similar to the first connecting plate 6, the second connecting plate 7 is fixedly connected to the second angle fixing plate 9 by bolts. The second angle fixing plate 9 is arranged in an L shape. One corner edge of the second angle fixing plate 9 is fixedly connected to the upper plate surface of the second connecting plate 7, and the other corner edge of the second angle fixing plate 9 is fixedly connected to the side wall of the second rack 43 to strengthen the structural strength of the connection between the second clamping plate 3 and the second rack 43, so as to improve the stability of the second clamping plate 3 when moving.

In this embodiment, the cross-sections of the first clamping groove 10 and the second clamping groove 11 are arranged in a relative V-shape. When the first clamping plate 2 and the second clamping plate 3 cooperate to clamp the bar material, the first clamping groove 10 and the second clamping groove 11 limit the bar material to improve the stability of the bar material when it is clamped and fixed. Furthermore, a slot 12 is provided on the surface of the first clamping plate 2 facing the second clamping plate 3, and the slot 12 is communicated with the first clamping groove 10, and a avoidance groove 13 is provided on the side of the surface of the second clamping plate 3 facing the first clamping plate 2, so that an insertion block 14 is formed at one end of the second clamping plate 3 facing the first clamping plate 2, and the insertion block 14 is movably inserted in the slot 12. When the first clamping plate 2 and the second clamping plate 3 cooperate to clamp the rod, the insertion block 14 is inserted into the slot 12, so that it is difficult for the first clamping plate 2 and the second clamping plate 3 to shake, which is beneficial to further improve the stability of the rod when it is clamped and fixed.

[0042] The implementation principle of a clamping device in an embodiment of the present application is as follows: when it is necessary to clamp and fix a large diameter bar, the output shaft of the driving motor 51 drives the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 53 meshing with it to rotate, and the driven gear 53 drives the linkage gear 41 to rotate through the connecting shaft 54, and the linkage gear 41 drives the first rack 42 and the second rack 43 to move away from each other in the vertical direction, and the first rack 42 and the second rack 43 respectively drive the first clamping plate 2 and the second clamping plate 3 to move away from each other, so that the large diameter bar enters the position between the first clamping plate 2 and the second clamping plate 3, and then the output shaft of the driving motor 51 drives the driving gear 52 to rotate in the opposite direction, and the driving gear 52 drives the driven gear 53 to rotate in the opposite direction. The gear 52 drives the driven gear 53 meshing with it to rotate in the opposite direction, and the driven gear 53 drives the linkage gear 41 to rotate in the opposite direction through the connecting shaft 54. The linkage gear 41 drives the first rack 42 and the second rack 43 to move toward each other in the vertical direction. The first rack 42 and the second rack 43 respectively drive the first clamping plate 2 and the second clamping plate 3 to move toward each other to achieve clamping and fixing of large diameter bars. The setting of the linkage gear 41, the first rack 42 and the second rack 43 increases the movable range of the first clamping plate 2 and the second clamping plate 3, and facilitates the clamping operation of large diameter bars, which is beneficial to improve the applicability of the clamping device and the clamping stability of large diameter bars.
