[0026] like Figure 6As shown, the bar clamping device includes a workbench 5, on which a tool for sawing a small-diameter bar 3 is placed. Figure 1 and Figure 2 As shown, the special tooling for sawing small diameter bars 3 comprises a first clamping plate 1 and a second clamping plate 2, and the first clamping plate 1 and the second clamping plate 2 are arranged opposite to each other. Figure 3 As shown, at least two protruding first clamping blocks 13 are spaced apart at both ends of the opposite surface of the first clamping plate 1, and a clamping groove 15 is formed between two adjacent first clamping blocks 13 at both ends of the first clamping plate 1. A first V-shaped notch 14 is formed on the end surface of the first clamping block 13 close to the second clamping plate 2, as shown in FIG. Figure 4 As shown, second clamping blocks 23 corresponding to the clamping groove 15 are provided at both ends of the opposite surface of the second clamping plate 2, and a second V-shaped notch 24 is provided on the end surface of the second clamping block 23 close to the first clamping plate 1. The second clamping block 23 is inserted into the corresponding clamping groove 15, and on the outer projection surface of the first clamping block 13, the first V-shaped notch 14 and the second V-shaped notch 24 form a clamping hole 4 for clamping the rod 3. Furthermore, in this embodiment, the second V-shaped notch 24 and the first V-shaped notch 14 have the same size, that is, the formed clamping hole 4 is a diamond hole. Furthermore, the angle between the first V-shaped notch 14 and the second V-shaped notch 24 is a right angle, so the clamping hole 4 is a square hole. When in use, Figure 5 As shown, a plurality of small diameter rods 3 are inserted into the clamping hole 4, and then the first clamping plate 1 and the second clamping plate 2 are relatively moved, so that the clamping hole 4 is reduced, thereby clamping the plurality of small diameter rods 3.

[0027] In this embodiment, if Figure 3 and Figure 6 As shown, two protruding first clamping blocks 13 are provided at both ends of the first supporting plate, and the width of the clamping groove 15 is consistent with the width of the second clamping block 23, thereby making the special tooling structure more compact, and at the same time avoiding the first clamping block 13 and the second clamping block 23 from shaking left and right relative to the second clamping block 23 when clamping the rod 3. Moreover, after the rod 3 is clamped, the rod 3 between the first clamping block and the second clamping block 23 has three force points, and the three force points are distributed in a triangle, which facilitates the clamping of the rod 3.

[0028] In this embodiment, if Figure 6 As shown, a baffle plate 6 is installed on the workbench 5, and the second clamping plate 2 is in contact with the baffle plate 6. A driving mechanism 8 is also installed on the workbench 5, and the driving mechanism 8 pushes the first clamping plate 1 to move toward the second clamping plate 2. In this embodiment, the second clamping plate 2 is stationary, and the first clamping plate 1 moves. The driving mechanism 8 pushes the first clamping plate 1 to move toward the second clamping plate 2, thereby gradually shrinking the clamping hole 4, thereby clamping the rod 3.

[0029] In this embodiment, if Figure 3 and 6 As shown, two raised first ridges 11 are provided on the back of the first clamping plate 1, and the two first ridges 11 are arranged at intervals, and a first limiting groove 12 is formed between the two first ridges 11. A push plate 7 cooperating with the first limiting groove 12 is provided at the power output end of the driving mechanism 8. Through the cooperation between the push plate 7 and the first limiting groove 12, after the first clamping plate 1 and the push plate 7 are installed, the first clamping plate 1 cannot swing left and right relative to the push plate 7, and the first clamping plate 1 is placed on the workbench 5. Therefore, when the push plate 7 moves, the moving trajectory of the first clamping plate 1 can be guaranteed, thereby enabling better clamping of the visual rod 3.

[0030] In this embodiment, the driving mechanism 8 is driven by a hydraulic cylinder or a screw pair. When the hydraulic cylinder is selected, a push plate 7 is installed on the telescopic shaft of the hydraulic cylinder. When the screw pair is selected, a bearing is provided on the push plate 7, and one end of the screw of the screw pair is lower than the bearing.

[0031] In this embodiment, if Figure 4 and Figure 6 As shown, two raised second ridges 21 are provided on the back side of the second clamping plate 2. The two second ridges 21 are arranged at intervals, and a second limiting groove 22 is formed between the two second ridges 21. The baffle plate 6 cooperates with the second limiting groove 22, so that the second clamping plate 2 cannot swing left and right relative to the baffle plate 6. The baffle plate 6 is installed on the workbench 5 and the baffle plate 6 is stationary, so that the second clamping plate 2 is stationary during the process of clamping the rod 3, further ensuring the reliability of the first clamping plate 1 and the second clamping plate 2 in clamping the rod 3.

[0032] The working process of the utility model is as follows: the second limiting groove 22 of the second clamping plate 2 is installed on the baffle 6, and then the first limiting groove 12 of the first clamping plate 1 is installed on the push plate 7, and then the driving mechanism 8 is controlled to move, so that the first clamping plate 1 moves toward the second clamping plate 2. When the second clamping block 23 enters the clamping groove 15, a clamping hole 4 is formed between the first clamping block 13 and the second clamping block 23. Then the driving mechanism 8 stops working, and a plurality of rods 3 are inserted from the clamping hole 4, and then the driving mechanism 8 works again. At this time, the movement of the first clamping plate 1 toward the second clamping plate 2 will shrink the clamping hole 4. In the process of shrinking the clamping hole 4, a plurality of rods 3 are tightly woven from loose ones. When the clamping hole 4 cannot be shrunk, it indicates that a plurality of rods 3 are clamped. In this embodiment, when the first clamping block 13 opens the first V-shaped notch 14, it directly clamps the upper and lower end surfaces of the first clamping block 13. The second clamping block 23 is opened at the same place. Similarly, when the second V-shaped notch 24 is opened, the second clamping block 23 is also opened directly from the upper and lower end surfaces of the second clamping block 23. In this way, the bottom and top of the first clamping block 13 will form triangular blocks, and the bottom and top of the second clamping block 23 will also form triangular blocks. Therefore, the sharp corners of the triangular blocks have the function of scooping up the rod 3. At this time, when the rod 3 is clamped, the rod 3 is directly placed on the workbench 5 between the first overtime plate and the second clamping plate 2, and then the first clamping plate 1 moves toward the second clamping plate 2. During the movement, the triangular block of the first clamping plate 1 will push the rod 3 toward the second clamping plate 2, and when the first clamping block 13 meets the second clamping block 23, the rod 3 will roll along the inclined surface of the triangular block, and then scoop up the rod 3. The scooped rod 3 is located in the clamping hole 4. As the clamping hole 4 shrinks, a number of rods 3 are clamped, thereby facilitating the subsequent cutting of the rod 3.

[0033] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
