The rotating threaded rod 17 drives the surface sleeve plate 19 to move horizontally with the help of the second slide rail 14 and the second slider 18.

[0016] The clamping device 3 includes a bottom plate 31, the bottom end of the bottom plate 31 is fixedly connected to the top of the workbench 1, a rotating shaft 32 is rotatably connected to the middle of the top of the bottom plate 31, a shaft plate 33 is fixedly connected to the top of the rotating shaft 32, the center point of the shaft plate 33 is consistent with the center point of the rotating shaft 32, both sides of the bottom end of the shaft plate 33 are rotatably connected to connecting plates 34, the two connecting plates 34 have the same length, four third slide rails 35 are fixedly connected to the bottom end of the bottom plate 31, the outer surfaces of the four third slide rails 35 are sleeved with third sliders 36, the tops of the two third sliders 36 on the same vertical horizontal side are commonly fixedly connected to a seat plate 37, one end of the two connecting plates 34 is rotatably connected to one side of the bottom end of the two seat plates 37, and one end of the two seat plates 37 is fixedly connected There are two rotating parts 38, and the outer surfaces of the four rotating parts 38 are all rotatably connected with rollers 39. The four rollers 39 can perform self-centering adjustment of the mechanical parts through synchronous opposite movements. A second motor 40 is fixedly installed inside the workbench 1. The output end of the second motor 40 is fixedly connected to the bottom end of the rotating shaft 32. When the mechanical parts need to be processed, the mechanical parts are placed between the two seat plates 37 in the clamping device 3. The output end of the second motor 40 drives the rotating shaft 32 to rotate, and the rotating rotating shaft 32 drives the shaft plate 33 to rotate. The rotating shaft plate 33 drives the two seat plates 37 to move through the connecting plates 34 on both sides. The rotational force causes the two seat plates 37 to perform opposite clamping movement under the rotation of the two connecting plates 34. The width of the moving plate 13 is consistent with that of the bottom plate 31, and the height of the moving plate 13 is higher than that of the bottom plate 31. The two first slide rails 11 and the first slider 12 are distributed in a mirror image. The support plate 20 is in a "U" shape. The moving plate 13 with the same width as the bottom plate 31 provides a fixed moving distance for the support plate 20, ensuring that the horizontal moving distance of the support plate 20 does not exceed the maximum width of the bottom plate 31. The two first slide rails 11 and the first slider 12 distributed in a mirror image help the moving plate 13 to move linearly under the push of the cylinder 25. The four third slide rails 35 are distributed in a rectangular array, the rotating shaft 32 is located at the center of the bottom plate 31, and the two connecting plates 34 are distributed in a ring array. The four third slide rails 35 distributed in a rectangular array provide stable linear motion on the same horizontal line for the two seat plates 37. The connecting plates 34 in a ring array rotate with the rotating shaft 32 as the center of the rotation circle through the rotation of the rotating shaft 32 at the center, and the rotating force is converted into opposite movement in the relative direction under the restriction of the four third slide rails 35.
[0017] Working principle: when it is necessary to process mechanical parts, the mechanical parts are placed between the two seat plates 37 in the clamping device 3, and the second motor 40 is started. The output end of the second motor 40 drives the rotating shaft 32 to rotate, and the rotating rotating shaft 32 drives the shaft plate 33 to rotate. The rotating shaft plate 33 drives the connecting plates 34 on both sides to rotate radially synchronously. The rotating two connecting plates 34 thereby drive the two seat plates 37 to move horizontally along the third slide rail 35 through the third slider 36. The rotational force causes the two seat plates 37 to perform opposite clamping movements under the rotation of the two connecting plates 34. The two oppositely moving seat plates 37 engage the four end faces of the mechanical parts through the four rollers 39 on the upper part, and push the mechanical parts to the center of the bottom plate 31 under the rotation of the four rollers 39, thereby achieving the purpose of self-centering clamping of the mechanical parts. When it is necessary to clamp and fix the mechanical parts When the mechanical parts are being processed, the cylinder 25 is started, and the output end of the cylinder 25 pushes out or retracts the fixed block 24, so that the movable plate 13 connected to the fixed block 24 is moved horizontally with the help of the first slider 12 and the first slide rail 11, so as to achieve the purpose of controlling the movable plate 13 to move forward and backward, and then the first motor 10 is started, and the output end of the first motor 10 drives the threaded rod 17 to rotate between the fixing part 16 and the side plate 15, and the rotating threaded rod 17 drives the sleeve plate 19 to move along the outer surface of the threaded rod 17, and the movable sleeve plate 19 is moved horizontally with the help of the second slide rail 14 and the second slider 18. After the movement is completed, the processing head 23 is moved horizontally up and down by the electric slide rail 21 and the electric slide 22 at one end of the support plate 20. Through multiple movements and coordination, the purpose of multi-directional processing of mechanical parts is achieved.
