Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the invention

[0023] like Figure 1When processing the inner wall gear teeth of the gear 57, the four moving columns 2 are driven horizontally in the directions away from each other by the first driving member at the same time. After moving to the appropriate position, the gear 57 is placed on the top of the four pads 5 on the processing table 1, and the four moving columns 2 are located on the outside of the gear 57.

At this time, the fixing of the gear 57 is completed. At this time, the situation that the inner wall gear teeth processing of the gear 57 is affected when the four moving columns 2 and the clamping plates 4 fix the gear 57 can be reduced. like Figure 7 When processing the outer wall gear teeth of the gear 57, the four moving columns 2 are driven horizontally in the direction of approaching each other by the first driving member at the same time.

The second disc 8 is located below the first disc 7 and is coaxial with the first disc 7. The second disc 8 is rotatably connected to the top of the support plate 9. Four long strip grooves 10 are opened at the top of the processing table 1, and the four long strip grooves 10 are evenly distributed along the circumference of the processing table 1. Four long strip slide grooves 12 are opened at the top of the first disc 7, and the four slide grooves 12 are The four sliding grooves 12 are evenly distributed along the circumference of the first disk 7 and correspond to the four long strip grooves 10 one by one. The four sliding grooves 12 are horizontally slidably connected with sliders 13, and the tops of the four sliders 13 are provided with circular grooves 14. The four circular grooves 14 are vertically slidably connected with vertical columns 15, and the tops of the four vertical columns 15 vertically pass through the four long strip grooves 10 respectively, and are coaxially fixedly connected to the bottom ends of the four moving columns 2 respectively. The bottom ends of the four vertical columns 15 extend outside the circular grooves 14 and are provided with fixed blocks 16, and the tops of the four fixed blocks 16 are provided with tension springs 17, and the tops of the four tension springs 17 The four slide grooves 12 are respectively fixedly connected to the bottom ends of the four sliders 13, and the four slide grooves 12 are horizontally slidably connected with a push block 18 located on one side of the slider 13, and the four push blocks 18 are provided with a first spring 19 on one side close to the slider 13, and the four first springs 19 are respectively fixedly connected to the four sliders 13 at one end of the push block 18, and the bottom ends of the four push blocks 18 are vertically provided with a push column 20, and the top of the second disk 8 is provided with four first arc grooves 21, and the four first arc grooves 21 are uniformly distributed along the circumference of the second disk 8, and the bottom ends of the four push columns 20 pass through the four first arc grooves 21 respectively, and the support plate 9 is provided with A first motor 22 is provided for driving the second disc 8 to rotate, and the second driving member includes grooves 23 each opened on one side of the four fixed blocks 16.

[0025] like Figure 1 and Figure 2When it is necessary to drive the four moving columns 2 to move horizontally in the direction of approaching or moving away from each other at the same time, it is only necessary to turn on the first motor 22. At this time, the rotating shaft of the first motor 22 will drive the second disc 8 to rotate. At this time, the second disc 8 will respectively push the four push blocks 18 to move in the direction of moving away from or approaching each other in the slide groove 12 through the cooperation of the four first arc grooves 21 and the four push columns 20. At this time, the four sliders 13 will all slide along the push blocks 18 through the first springs 19. At this time, the four sliders 13 will respectively drive the four vertical columns 15 to move in the direction of moving away from or approaching each other. At this time, the four vertical columns 15 will respectively drive the four moving columns 2 to move horizontally in the direction of moving closer to or away from each other. When the second disc 8 rotates clockwise, the four moving columns 2 move closer to each other, and when the second disc 8 rotates counterclockwise, the four moving columns 2 move away from each other. When the four moving columns 2 approach each other until the four moving columns 2 contact the outer wall of the gear 57, the first motor 22 continues to work, so that the second disc 8 continues to rotate clockwise. At this time, because the four moving columns 2 are in contact with the outer wall of the gear 57, the four moving columns 2 will stop moving. At this time, the push block 18 will move away from the slider 13, so that the first spring 19 is stretched.

At this time, because the four moving columns 2 are in contact with the inner wall of the gear 57, the four moving columns 2 will stop moving. At this time, the push block 18 will approach the slider 13, so that the first spring 19 is compressed. At this time, through the cooperation of another push plate 26 on the four horizontal plates 24 and the isosceles triangle blocks 25 in the four grooves 23, the four fixed blocks 16 can be moved vertically downward at the same time, and the tension spring 17 is stretched. At this time, the four fixed blocks 16 will pull the four moving columns 2 to move vertically downward through the vertical column 15 until the clamping plates 4 on the four moving columns 2 contact the top of the gear 57 and press the gear 57 against the pad 5. It is simple and convenient to use.

Four second arc grooves 28 are opened on the top of the driven disk 27, and the four second arc grooves 28 are evenly distributed along the circumference of the driven disk 27. The tops of the four vertical columns 15 pass through the four second arc grooves 28 respectively. The purpose of this arrangement is that when the four vertical columns 15 move horizontally, the four vertical columns 15 will drive the driven disk 27 to rotate on the processing table 1 through the second arc grooves 28. At this time, through the cooperation of the four second arc grooves 28 on the driven disk 27 and the four vertical columns 15, the moving distances of the four moving columns 2 can be made consistent, which is convenient for the four moving columns 2 to position the gear 57. The friction resistance of the slider 13 when moving in the slide groove 12 and the resistance of the vertical column 15 driving the driven disk 27 to rotate through the second arc groove 28 are added together, which is less than the elastic force of the first spring 19, and it is simple and convenient to use.

The bottom ends of the four columns 33 pass through the four driving grooves 36 respectively, and a first driving member for driving the swivel 34 to rotate is provided on the processing table 1.

[0028] like Figure 4 and Figure 5When it is necessary to simultaneously drive the four moving columns 2 to move horizontally in the direction of approaching or moving away from each other, it is only necessary to drive the swivel 34 to rotate through the first driving member. At this time, the swivel 34 will drive the four driving plates 35 to rotate along the rotation axis of the swivel 34. At this time, through the cooperation of the driving grooves 36 on the four driving plates 35 and the columns 33 on the four slides 30, the four slides 30 can be simultaneously driven to move in the direction of approaching or moving away from each other in the slideway 29. At this time, because the four threaded cylinders 32 are respectively arranged on the four slides 30, and the four threaded cylinders 32 are respectively threadedly connected to the threaded grooves 31 on the four moving columns 2, when the four slides 30 move in the direction of approaching or moving away from each other in the slideway 29, the four moving columns 2 will respectively follow the four slides 30 to move, which is simple and convenient to use.

[0029] like Figure 4 The first driving member includes a cantilever 37 arranged on one side of the processing table 1 and a rotating block 38 rotatably connected to the top of one of the driving plates 35. The bottom end of the cantilever 37 is rotatably connected to a rotating plate 39, and a second motor 40 is provided on one side of the rotating plate 39. One end of the rotating shaft of the second motor 40 passes through the rotating plate 39 and is provided with a screw rod 41, and the end of the screw rod 41 away from the second motor 40 passes through the rotating block 38 and is threadedly connected to the rotating block 38.

[0030] like Figure 4 When it is necessary to drive the swivel ring 34 to rotate, it is only necessary to turn on the second motor 40. At this time, the rotating shaft of the second motor 40 will drive the screw rod 41 to rotate. At this time, because the end of the screw rod 41 away from the second motor 40 passes through the rotating block 38 and is threadedly connected to the rotating block 38, the rotating block 38 is rotatably connected to one of the driving plates 35, and the rotating plate 39 is rotatably connected to the cantilever 37. The cantilever 37 is set on the processing table 1, so when the screw rod 41 rotates, the rotating block 38 can be pushed to move in the direction away from or close to the rotating plate 39. At this time, the rotating block 38 will drive the swivel ring 34 to rotate on the fixed ring 56 through one of the driving plates 35. When the rotating block 38 moves in the direction away from or close to the rotating plate 39, the rotating plate 39 will rotate on the cantilever 37, and the rotating block 38 will rotate on the driving plate 35. The rotating block 38 will not follow the screw rod 41 to rotate along the rotation axis of the screw rod 41, which is simple and convenient to use.

[0031] like Figure 4 and Figure 5 and Figure 6Alternatively, the second driving member includes a bottom plate 42, and the bottom plate 42 is arranged between the four legs 3, the tops of the four slide plates 30 are each provided with a rotation groove 43 connected to the threaded tube 32, and the four rotation grooves 43 are rotatably connected to the rotation shaft 44, the bottoms of the four threaded grooves 31 are each provided with a rectangular groove 45, and the four rectangular grooves 45 are each vertically slidably connected to a rectangular rod 46, the bottom ends of the four rectangular rods 46 are each extended outside the rectangular groove 45 and are respectively fixedly connected to the four rotation shafts 44, the bottom ends of the four rotation shafts 44 are each provided with a first turntable 47 located below the processing table 1, and the top of the bottom plate 42 is rotatably connected to the four A second turntable 48 is provided, and the four second turntables 48 correspond to the four first turntables 47 up and down. A transmission disk 49 is placed between the four second turntables 48 and the first turntable 47. The top and bottom ends of the four transmission disks 49 are horizontally provided with long strip transmission rods 50 distributed along the diameter direction of the transmission disk 49, and the two transmission rods 50 on the transmission disk 49 are perpendicular to each other. The four second turntables 48 and the first turntable 47 are provided with transmission grooves 51 for horizontally sliding the two transmission rods 50 on the transmission disk 49 respectively. A second driving member for simultaneously driving the four second turntables 48 to rotate is provided on the bottom plate 42.

[0032] like Figure 4 and Figure 5 and Figure 6 When it is necessary to drive the moving column 2 to move vertically downward, it is only necessary to drive the four second rotating disks 48 to rotate simultaneously through the second driving member. At this time, a transmission disk 49 is placed between the second rotating disk 48 and the first rotating disk 47, and the second rotating disk 48 and the first rotating disk 47 are provided with transmission grooves 51 for horizontal sliding of two transmission rods 50 on the transmission disk 49, respectively. Therefore, when the second rotating disk 48 rotates, the transmission groove 51 on the second rotating disk 48 cooperates with the bottom transmission rod 50 on the transmission disk 49, and the transmission groove 51 on the first rotating disk 47 cooperates with the top transmission rod 50 on the transmission disk 49. When the first rotating disk 47 is closed, the first rotating disk 47 can be driven to rotate. At this time, the first rotating disk 47 will drive the rotating shaft 44 to rotate in the rotating groove 43. The rotating shaft 44 will drive the moving column 2 to rotate through the cooperation of the rectangular rod 46 and the rectangular groove 45. At this time, because the threaded cylinder 32 is fixedly connected to the slide plate 30, and the threaded cylinder 32 is threadedly connected to the threaded groove 31 on the moving column 2, when the moving column 2 rotates, the moving column 2 will move vertically downward through the cooperation of the threaded cylinder 32 and the threaded groove 31. At this time, the rectangular rod 46 will gradually enter the rectangular groove 45, and the top end of the rectangular rod 46 is always located in the rectangular groove 45. When the four slides 30 move in the direction of approaching or moving away from each other in the slideway 29, the second turntable 48 and the first turntable 47 will be misaligned with each other. At this time, the two transmission rods 50 on the transmission disk 49 will move in the transmission groove 51 on the second turntable 48 and the transmission groove 51 on the first turntable 47 respectively, and the two transmission rods 50 on the transmission disk 49 will not be completely moved out of the two transmission grooves 51. After the four slides 30 move to the appropriate position, the second turntable 48 rotates. At this time, through the cooperation of the transmission groove 51 on the second turntable 48 and the bottom transmission rod 50 on the transmission disk 49, and the cooperation of the transmission groove 51 of the first turntable 47 and the top transmission rod 50 on the transmission disk 49, the first turntable 47 can still be driven to rotate, which is simple and convenient to use.

[0033] like Figure 5 The second driving member includes a first gear 52 coaxially arranged on the four second turntables 48 and a second gear 53 rotatably connected to the top center of the bottom plate 42 and meshing with the four first gears 52. A third motor 54 for driving the second gear 53 to rotate is provided on the bottom plate 42. The purpose of this setting is that when it is necessary to drive the four second turntables 48 to rotate at the same time, it is only necessary to turn on the third motor 54. At this time, the rotating shaft of the third motor 54 will drive the second gear 53 to rotate. At this time, the second gear 53 will simultaneously drive the four second turntables 48 to rotate through the four first gears 52 meshing therewith, which is simple and convenient to use.

[0034] like Figure 1 The bottom ends of the four clamping plates 4 are detachably connected with contact pads 55, and the purpose of this arrangement is to reduce the situation that the bottom ends of the clamping plates 4 directly contact with the top ends of the gears 57, which causes the clamping plates 4 or the gears 57 to wear, and the use is simple and convenient.

After moving to the appropriate position, the gear 57 is placed on the top of the four pads 5 on the processing table 1, and the four moving columns 2 are located on the inner side of the gear 57. Then, the four moving columns 2 are driven horizontally away from each other by the first driving member at the same time until the four moving columns 2 are in contact with the inner wall of the gear 57. At this time, the gear 57 can be positioned. Then, the four moving columns 2 are driven vertically downward by the second driving member at the same time until the clamping plates 4 on the four moving columns 2 are in contact with the top of the gear 57 and the gear 57 is pressed against the pad 5. At this time, the gear 57 can be fixed. At this time, the influence of the four moving columns 2 and the clamping plates 4 on the gear 57 when machining the teeth of the outer wall of the gear 57 can be reduced.
