[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments of the following public specification.

[0021] See also Figure 1-4 The utility model provides a parts processing clamping device, including a base 1, a ring plate 2 is fixedly connected to the top of the base 1, a circular plate 3 is fixedly connected to the top of the circular plate 2 through a bracket, and three symmetrical slide grooves 6 are opened on the surface of the circular plate 3 and penetrated by the ring plate 3, each slide groove 6 has a clamping column 1 4 and a clamping column 2 5, the three clamping columns 1 4 can be separated from each other to contact the inner wall of the circular workpiece, and the three clamping columns 2 5 can be close to each other to contact the outer wall of the circular workpiece. When the device is used to clamp the circular parts When clamping, the annular workpiece can be placed on the circular plate 3 first. At this time, the three clamping columns 1 4 will be located inside the circular plate 3, and the three clamping columns 2 5 will be located outside the circular plate 3. The three clamping columns 2 5 can be approached to each other to clamp and fix the annular workpiece on the circular plate 3, and the three clamping columns 1 4 can be moved away from each other to make the clamping columns 1 4 contact the inner wall of the circular plate 3 to support and protect the inner wall of the circular plate 3, which can effectively prevent the problem of deformation of the contact part between the clamping columns 2 5 and the circular plate 3 due to extrusion.

[0022] In order to enable the three clamping columns 4 to move away from each other, it is proposed that three symmetrical sliding blocks 7 are slidably connected in the sliding groove 6, the three clamping columns 4 are fixedly connected to the tops of the three sliding blocks 7, the base 1 is a hollow structure inside and has an opening on the top, the base 1 is provided with a liftable adjustment block 8, three symmetrical and inclined push rods 9 are hinged on the adjustment block 8, the tops of the three push rods 9 are rotatably connected to the bottoms of the three sliding blocks 7, so that when the position of the adjustment block 8 rises, the three push rods 9 can be driven to move synchronously, so that the tops of the three push rods 9 can push the three sliding blocks 7 to slide along the clamping column 4, and at this time the three clamping columns 4 can move away from each other, so that they can contact the inner wall of the annular workpiece and play a supporting and protective role.

[0023] The specific way in which the adjusting block 8 can be raised and lowered is as follows: Figure 2 As shown, a servo electric cylinder 10 with a piston rod facing upward is fixedly installed at the bottom of the inner wall of the base 1, and the end of the piston rod of the servo electric cylinder 10 is fixedly connected to the bottom of the adjustment block 8. When the piston rod of the servo electric cylinder 10 is extended or retracted, it can drive the adjustment block 8 to move up and down in the base 1, so as to realize the movement of the three clamping columns 4 away from / close to each other.

[0024] In order to enable the three clamping columns 2 5 to move closer to each other, a threaded rod 12 can be rotatably connected to each of the three slide grooves 6 through a bearing, and each of the three slide grooves 6 is inserted with a slider 2 11 that is sleeved on the corresponding threaded rod 12 through a threaded fit. The three clamping columns 2 5 are respectively fixedly connected to the tops of the three sliders 2 11, and a rotating assembly for simultaneously rotating the three threaded rods 12 is provided on the annular plate 2. When the three threaded rods 12 rotate simultaneously, the slider 2 11 can slide along the slide groove 6 under the cooperation of the threads, so that the three clamping columns 2 5 can move closer to each other following the sliding of the slider 2 11, so that the surface of the annular workpiece can be clamped and fixed.

[0025] Furthermore, the rotating assembly includes three rotating shafts 13 symmetrically arranged on the top of the annular plate 2, and the top of each rotating shaft 13 is fixedly connected to a driving bevel gear 14, and one side of each threaded rod 12 extends outside the circular plate 3 and is fixedly connected to a driven bevel gear 15 meshing with the corresponding driving bevel gear 14. A driving assembly for driving the three rotating shafts 13 to rotate simultaneously is provided on the annular plate 2. When the rotating shaft 13 rotates, it can drive the driving bevel gear 14 to rotate, so that the driving bevel gear 14 can drive the driven bevel gear 15 to rotate synchronously through tooth matching, so that the three threaded rods 12 can rotate synchronously.

[0026] At the same time, the driving component includes a servo motor 2 fixedly installed in the annular plate 2, and the end of the output shaft of the servo motor 2 is fixedly connected to the bottom of one of the rotating shafts 13. Two synchronous wheels 16 are fixedly sleeved on the rotating shaft 13. The bottoms of the remaining two rotating shafts 13 are rotatably connected to the top surface of the annular plate 2 through bearings, and synchronous wheels 2 161 are sleeved on their surfaces. A synchronous belt 17 is wound around the two synchronous wheels 16 and the corresponding synchronous wheels 2 161 through teeth. The servo motor 2 can drive the rotating shaft 13 to rotate, and because the three rotating shafts 13 are connected to the synchronous wheel 1 16 / synchronous wheel 2 161 through the synchronous belt 17, the three rotating shafts 13 will rotate synchronously, thereby achieving the effect of the three clamping columns 2 5 moving closer to / away from each other.
