The clamping mechanism 4 includes a screw nut block 7 provided on the screw 3, and a support block 8 is connected to the screw nut block 7. Two abutment blocks 9 are provided on the outer side of the support block 8, and a sliding block 11 is provided between the two abutment blocks 9. An air bag 14 is installed on the outer side of the sliding block 11, and a rubber block is provided on the outer side of the air bag 14. A slide groove 10 is provided on the opposite side of the two abutment blocks 9, and the two ends of the sliding block 11 are located at the positions of the two ends of the sliding block 11. In the slide groove 10, a movable groove 15 is opened at a position corresponding to the abutment block 9 on the support block 8, a part of the abutment block 9 is located in the movable groove 15, a spring 19 is connected between the inner side of the abutment block 9 and the side wall of the movable groove 15, a limiting groove 16 is opened on the side of the movable groove 15, a limiting block 17 is connected to the abutment block 9, the limiting block 17 is located in the limiting groove 16, a trigger 18 is arranged at the inner end of the limiting groove 16, a rack 21 is connected to the inner side of the sliding block 11, and a positioning groove 21 is opened at a position corresponding to the rack 21 on the support block 8 0, a part of the rack 21 is located in the positioning groove 1 20, a connecting groove 22 is arranged between the positioning groove 1 20 and the movable groove 15, the connecting groove 22 is respectively connected with the positioning groove 1 20 and the movable groove 15, a transmission gear 23 is rotatably arranged in the connecting groove 22, the rack 21 is meshed with the transmission gear 23, a rack 24 is connected to the inner end of the abutment block 9, the rack 24 is meshed with the transmission gear 23, an air pump 12 is arranged on the outer side of the support block 8, an air pipe 13 is arranged on the sliding block 11, and both ends of the air pipe 13 are connected with the air bag 14 and the air pump 12.

[0023] The driving motor 145 drives the driving shaft 146 to rotate, so that the driving bevel gear 147 on the driving shaft 146 drives the meshing driven bevel gear 149 to rotate, and the driven bevel gear 149 then drives the screw 13 to rotate. When the screw 13 rotates, the screw nut block 7 is controlled to move. When the gear is fixed, the screw nut block 7 is controlled to drive the support block 8 to move outward. The abutment block 9 on the support block 8 first contacts the inner wall of the gear. As the support block 8 continues to move outward, the abutment block 9 is pressed into the movable groove 15 by the inner wall of the gear. In this process, the rack 124 on the abutment block 9 drives the transmission gear 23 to rotate, and the transmission gear 23 then acts on the rack 21 to make the rack 21 move in the opposite direction to the abutment block 9.

For gears with different inner diameters, the inflation of the airbag 14 can effectively make the rubber block contact the inner wall of the gear.

[0024] like Figure 4 As shown, a sleeve 25 is inserted into the air pipe 13, and the sleeve 25 is arranged to penetrate the upper end surface of the air pipe 13. An exhaust pipe 26 is arranged in the sleeve 25, and an exhaust hole 27 is opened in the middle of the exhaust pipe 26. The upper end of the exhaust hole 27 is connected to the upper end of the exhaust pipe 26, that is, the upper end of the exhaust hole 27 penetrates the upper end surface of the exhaust pipe 26, and the lower end of the exhaust hole 27 does not penetrate the lower end surface of the exhaust pipe 26. A toothed ring 28 is connected to the upper end of the exhaust pipe 26, and the outer diameter of the toothed ring 28 is not less than the inner diameter of the sleeve 25. A connecting hole 29 is provided on the side wall of the tube 26, and the connecting hole 29 penetrates the side wall of the exhaust pipe 26. An air inlet hole 30 is provided on the side wall of the sleeve 25, and the air inlet hole 30 penetrates the side wall of the sleeve 25. The center of the connecting hole 29 and the center of the air inlet hole 30 are located at the same height, and the diameter of the connecting hole 29 is not less than the diameter of the air inlet hole 30. A driving motor 2 31 is provided on the upper part of the air pipe 13, and the driving motor 2 31 is connected to the driving gear 66, and the driving gear 66 is meshed with the gear ring 28.

[0025] The driving gear 66 is driven to rotate by the driving motor 2 31, and the driving gear 66 drives the meshing gear ring 28 to rotate to drive the exhaust pipe 26 to rotate in the sleeve 25. Thus, the connecting hole 29 is controlled to be aligned or staggered with the air inlet 30. When the connecting hole 29 is aligned with the air inlet 30, the inside of the air pipe 13 is connected with the outside, so that the air in the air bag 14 can flow into the air, and the air bag 14 can be compressed, thereby reducing the occupied space. When the connecting hole 29 is staggered with the air inlet 30, the air pipe 13 is separated from the outside, and the air pump 12 pumps air into the air bag 14 through the air pipe 13, which can make the air bag 14 inflate.

[0026] The upper part of the support block 8 is provided with a mounting groove 3 57, and the mounting block 32 is installed in the mounting groove 3 57. The mounting block 32 is fixed to the support block 8 by screws. The mounting block 32 is provided with a mounting groove 2 54, and a driving rod 55 is rotatably provided in the mounting groove 2 54. A lifting rod 56 is slidably installed on the mounting block 32, and the lifting rod 56 is limited to only being able to move up and down but not to rotate. The lifting rod 56 is perpendicular to the support block 8, and the upper end of the lifting rod 56 is connected to the pressing plate 53. A threaded hole is provided in the lifting rod 56, and the upper end of the driving rod 55 is located in the threaded hole and is threadedly connected to the threaded hole. A driving mechanism for driving the driving rod 55 to rotate is also provided on the support block 8. By rotating the driving rod 55, the height of the lifting rod 56 can be adjusted, thereby controlling the lifting and lowering of the pressing plate 53.

[0027] The pressing plate 53 can be pressed on the upper end surface of the gear after the supporting block 8 abuts against the inner wall of the gear, thereby cooperating with the processing table 1 to clamp the gear and further clamp and fix the gear.

[0028] The driving mechanism includes a rotating seat 35 installed on the support block 8, a transmission shaft 36 is rotatably arranged inside the rotating seat 35, the outer end of the transmission shaft 36 is connected to a transmission bevel gear 38, and limit rings 37 are arranged on the transmission shaft 36 at positions on both sides of the rotating seat 35. The setting of the limit rings 37 makes the axial positions of the transmission shaft 36 and the rotating seat 35 relatively fixed. A rotating seat 2 39 is provided on the screw nut block 7, and a transmission sleeve 40 is rotatably provided in the rotating seat 2 39. A part of the transmission shaft 36 is located in the transmission sleeve 40, and the transmission shaft 36 is slidably connected to the transmission sleeve 40. A driving shaft 2 33 is rotatably provided in the mounting groove 2 54, and a driven bevel gear 3 34 is connected to the upper part of the driving shaft 2 33, and the driven bevel gear 3 34 is meshed with the transmission bevel gear 1 38.

A rotating frame 52 is provided at the connection between the screw slot 2 and the driving slot 5, and the transmission sleeve 40 is rotatably provided on the rotating frame 52. Limiting rings 2 51 are provided at positions on the transmission sleeve 40 on both sides of the rotating frame 52. Through the action of the two limiting rings 2 51, the transmission sleeve 40 can rotate on the rotating frame 52 and will not move axially. One end of the transmission sleeve 40 away from the transmission shaft 36 is connected to a driven bevel gear 2 50 , and the upper end of the driving shaft 1 46 is connected to a driving bevel gear 2 48 , and the driving bevel gear 2 48 can mesh with the driven bevel gear 2 50 .

[0029] When the screw nut block 7 moves, the transmission shaft 36 is driven to move synchronously through the rotating seat 1 35, and the end of the transmission shaft 36 close to the transmission sleeve 40 moves in the transmission sleeve 40 without being disengaged from the transmission sleeve 40. The transmission bevel gear 1 38 on the transmission shaft 36 always keeps meshing with the driven bevel gear 3 34. When the transmission sleeve 40 drives the transmission shaft 36 to rotate, the driving shaft 2 33 is driven to rotate through the cooperation of the transmission bevel gear 1 38 and the driven bevel gear 3 34, and the driving shaft 2 33 drives the driving rod 55 to rotate through the cooperation of the transmission wheel 2 59, the transmission belt 60, and the transmission wheel 1 58, so as to drive the driving rod 55.

[0030] like Figure 5 As shown, a lifting mechanism is provided in the mounting groove 1 43, and a driving motor 1 45 is installed on the lifting mechanism. The lifting mechanism can drive the driving motor 1 45 to move up and down, so that the driving bevel gear 2 48 is meshed with the driven bevel gear 2 50 or the driving bevel gear 1 47 is meshed with the driven bevel gear 1 49, thereby driving the transmission sleeve 40 or the screw rod 1 3 to rotate respectively.

[0031] The lifting mechanism is a cylinder 44, which is located below a drive motor 45, and the upper end of a piston rod of the cylinder 44 is connected to the bottom of the drive motor 45.

[0032] like Figure 7As shown, a second limiting groove 41 is provided on the inner wall of the transmission sleeve 40, and the second limiting groove 41 is arranged along the axial direction of the transmission sleeve 40. A limiting strip 42 is connected to the outer wall of the transmission shaft 36, and the limiting strip 42 is located in the second limiting groove 41. Through the cooperation between the second limiting groove 41 and the limiting strip 42, the transmission shaft 36 can move in the transmission sleeve 40 along the axial direction, and the transmission sleeve 40 can drive the transmission shaft 36 to rotate.

[0033] like Figure 8 As shown, two groups of positioning mechanisms 6 are arranged on the processing table 1, and the two groups of positioning mechanisms 6 are symmetrically arranged with the center of the processing table 1 as the center. Each group of positioning mechanisms 6 includes a plurality of positioning grooves 61, and the plurality of positioning grooves 61 are evenly distributed along the radial direction of the processing table 1. A positioning block 62 is installed in the positioning groove 61, and a trigger block 63 is arranged at a position below the positioning block 62 in the positioning groove 61, and a spring 64 is connected between the bottom of the positioning block 62 and the bottom of the positioning groove 61. The two trigger blocks 63 located at the same radial position are connected to the same sensor 65 through a line. When the two trigger blocks 63 located at the same radial position are both triggered, the sensor 65 displays a correct signal. When only one of the trigger blocks 63 is triggered, it indicates that the position of the gear is incorrect, and the sensor 65 displays an error signal. When both trigger blocks 63 are not triggered, the sensor 65 does not display a signal. When the gear is clamped by the clamping mechanism 4, it will move on the processing table 1. When the gear is finally clamped and fixed, it can be judged whether the gear positioning is correct according to the signal of the sensor 65.

[0034] The positioning block 62 is generally cylindrical, and the upper end is a hemispherical structure. The diameter of the connection between the two is the same, and the connection between the two is located below the upper end surface of the processing table 1, so that the positioning block 62 will not cause any obstruction during the movement of the gear. During the movement of the gear, the edge will contact the outer periphery of the hemispherical structure, which can resist the positioning block 62 and press it into the second positioning groove 61.

[0035] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
