[0021] The control disk 8 is circular, and its main function is to limit and fix the slider 10 and the clamping block 11, ensuring that the parts to be processed can be clamped normally. At the same time, the silicone pad 12 is made of a soft material, and when clamping the parts to be processed, it can effectively protect the surface and prevent the surface of the parts from being damaged due to strong clamping force.

[0022] A connecting plate 2 13 is fixedly installed on one side of the slider 2 10 close to the connecting column 7 . There are four connecting plates 2 13 , and the four connecting plates 2 13 are all located on one side of the control panel 8 close to the connecting column 7 .

[0023] The four connecting plates 2 13 are all rectangular parallelepipeds, and their main function is to play a connecting role, ensuring that the slider 2 10 is slidably connected with the slide groove 2 9 under the driving action of the connecting rod 15, so as to achieve the effect of clamping the processing parts.

[0024] Among them, a fixed shaft 14 is fixedly installed on one side of the four connecting plates 2 close to the fixed plate 1 4, and a connecting rod 15 is rotatably connected to the outer side of the fixed shaft 14. The end of the connecting rod 15 away from the fixed shaft 14 is rotatably connected to the control plate 16. There are four connecting rods 15, and the four connecting rods 15 are all connected to the control plate 16, and the four connecting rods 15 are L-shaped.

[0025] The main function of the four connecting rods 15 is to be rotationally connected to the fixed shaft 14 and the control plate 16 respectively, so that when the control plate 16 rotates, the four connecting plates 13 can be controlled to move, thereby achieving the effect of convenient clamping.

[0026] Among them, the four connecting plates 2 13 are located at the bottom, and a fixing plate 2 17 is fixedly installed on one side of the connecting plate 2 13 close to the fixing plate 1 4, and a cylinder 18 is fixedly installed on the side of the fixing plate 2 17 away from the control console 1, and an output shaft 19 is fixedly installed on the output end of the cylinder 18. The four connecting plates 2 13 are located at the top, and a fixing block 20 is fixedly installed on one side of the connecting plate 2 13 close to the fixing plate 4, and a docking rod 21 is fixedly installed inside the fixing block 20, and the output shaft 19 and the docking rod 21 are fixedly installed.

[0027] There are two cylinders 18, and both cylinders 18 are fixedly connected to the fixed plate 17. Their main function is to control the output shaft 19 to extend and retract, thereby driving the connecting plate 13 to move through the docking rod 21, so as to achieve the effect of clamping the parts to be processed, and at the same time, parts of different rules and sizes can be clamped.

[0028] Among them, a connecting component 22 is fixedly installed at the bottom of the slider 1, and there are two connecting components 22. The two connecting components 22 are respectively located at the bottom of the console 1. A motor 23 is fixedly installed on the right side of the console 1. A screw 24 is fixedly installed at the output end of the motor 23. A limiting sleeve 25 is sleeved on the outer side of the screw 24. The limiting sleeve 25 is fixedly connected to the connecting component 22, and the screw 24 is meshed with the two connecting components 22.

[0029] The surface of the lead screw 24 is provided with threads, and the threads are distributed in relative directions to the left and right sides from the center point. The main function is to start the motor 23 to drive the lead screw 24 to rotate, and then drive the slider 1 3 to move in the relative direction, so as to clamp parts of different lengths.

[0030] Among them, there are two control panels 8, which are respectively located on the left and right sides of the center point of the console 1, there are two slide grooves 2, which are both located inside the console 1, there are four sliders 3, and the four sliders 3 are respectively slidably connected to the two slide grooves 2, and the four slide grooves 2 are respectively fixedly connected to the two connecting components 22.

[0031] The four sliders 3 are fixedly connected to the fixed plate 4 respectively. When the two connecting components 22 are engaged with the lead screw 24, the sliding action of the four sliders 3 and the two slide grooves 2 will drive the fixed plate 4 to move, thereby achieving the effect of facilitating clamping.

[0032] The working principle and use process of this utility model:

[0033] First, since the lead screw 24 is fixedly installed at the output end of the second motor 23, and the lead screw 24 and the connecting assembly 22 are in meshing shape, and since the threads on the surface of the lead screw 24 are distributed in opposite directions from the center point to both sides, when the second motor 23 is started, the two connecting assemblies 22 can be moved toward the center point of the console 1 at the same time through the rotation of the lead screw 24 and the connecting assembly 22, so as to achieve the effect of horizontally clamping the parts;

[0034] Secondly, the cylinder 18 is started again to drive the output shaft 19 to contract, so that the second connecting plate 13 slides toward the center of the control disk 8 through the sliding action of the second slider 10 and the second slide groove 9. At the same time, due to the rotation of the fixed shaft 14 and the connecting rod 15, the control plate 16 is driven to rotate, thereby driving multiple second connecting plates 13 to slide toward the center of the control disk 8 at the same time, thereby achieving the effect of clamping components with different diameter values;

[0035] At the same time, since a silicone pad 12 is fixedly installed on one side of the clamping block 11 close to the center point of the control panel 8, and since the material of the silicone pad 12 is relatively soft, when it comes into contact with the processing component, it will protect the contact surface of the component, thereby achieving the effect of not damaging the surface of the component;

[0036] Finally, the motor 5 is started to drive the control disk 8 to rotate through the connecting plate 6 and the connecting column 7, so that the clamped parts can be rotated, so that the parts can be processed in multiple directions, thereby improving the processing efficiency.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
