[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1 - Figure 2 、 Figure 5 , an embodiment provided by the present utility model: a high-precision positioning device for punching holes in the stator of a disc motor, including a support frame 1. The support frame 1 is a prior art. A punching component is arranged on its upper surface, which can punch holes in the stator of the disc motor and can be implemented by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. A driving component is arranged on the upper surface of the support frame 1, and a clamping component is arranged on the upper surface of the driving component. The driving component includes a cylindrical shell 21 that can make the clamping component move stably. The cylindrical shell 21 is fixedly connected to the upper surface of the support frame 1. The clamping component includes a hinge block 31. The hinge block 31 is slidably connected to the upper surface of the cylindrical shell 21. A connecting rod 32 is slidably connected to the inner wall of the right end of the hinge block 31. The rear end of the connecting rod 32 is hinged to a clamping plate 34. The clamping plate 34 is made of rubber material. The rubber material has a certain elasticity, ensuring that when the connecting rod 32 rotates, it can be smoothly stretched. When it contacts the stator, it can also rotate along the curvature of the outer wall of the stator, improving the fixing stability. A sliding rod 35 is fixedly connected to the lower surface of the hinge block 31.

[0033] Referring to Figure 1 - Figure 3 , the driving component further includes a rotating plate 23. The rotating plate 23 rotates circumferentially on the inner wall of the cylindrical shell 21. The rotating plate 23 is rotatably connected to the inner wall of the cylindrical shell 21. A first through groove 27 is formed on the upper surface of the rotating plate 23. The first through groove 27 has a certain slope, ensuring that when the rotating plate 23 rotates, the sliding rod 35 can move along the curvature of the first through groove 27. A second through groove 28 is formed on the upper surface of the cylindrical shell 21. A third through groove 29 is formed on the lower surface of the cylindrical shell 21. The third through groove 29 can ensure that the sliding can only move forward or backward. The outer wall of the bottom end of the sliding rod 35 is slidably connected to the third through groove 29, and the sliding rod 35 is slidably connected to the inner wall of the first through groove 27.

[0034] Referring to Figure 2 、 Figure 5The clamping assembly also includes a round rod 36. When the gear 33 rotates, the connecting rod 32 can be driven to rotate through the round rod 36 to ensure the stability of the rotation of the connecting rod 32. The round rod 36 penetrates and is rotatably connected to the lower surface of the right end of the hinge block 31. The upper surface of the round rod 36 is fixedly connected to the lower surface of the front end of the connecting rod 32. The lower surface of the round rod 36 is fixedly connected to a gear 33. The gear 33 is a prior art. It is a circular plate with multiple sets of teeth on the outer wall. The teeth are meshed with the rack 37 to ensure that the gear 33 rotates when it moves horizontally. The racks 37 are fixedly connected to the left and right sides of the inner wall of the through groove 28, and the gear 33 and the rack 37 are meshed with each other.

[0035] Reference Figure 2 - Figure 4 The driving assembly also includes a push handle 22. A worker can push the rotating plate 23 to rotate by holding the push handle 22. The push handle 22 is fixedly connected to the front surface of the rotating plate 23. The inner wall of the push handle 22 is elastically connected to the connecting plate 25 through a spring 26. The spring 26 always pushes the connecting plate 25 to move upward through its own elasticity to ensure the stability of the limiting rod 210. The connecting plate 25 is slidably connected to the inner wall of the push handle 22. One end of the spring 26 is fixedly connected to the lower surface of the rear end of the connecting plate 25, and the other end of the spring 26 is fixedly connected to the inner wall of the push handle 22. The cylindrical shell 2 The inner wall of the front end is provided with grooves in multiple groups. The multiple groups of grooves are provided so that the clamping assembly can fix the limit points of stators of different sizes. The rear end of the upper surface of the connecting plate 25 is fixedly connected with the limit rod 210. The limit rod 210 penetrates and is slidably connected to the rear end of the upper surface of the push handle 22. The top of the limit rod 210 contacts the inner wall of the groove. The front end of the upper surface of the push handle 22 penetrates and is slidably connected with a button 24. By pressing the button 24, the limit rod 210 can be driven to move, which improves convenience. The lower surface of the button 24 is fixedly connected to the front end of the upper surface of the connecting plate 25.

[0036] Working principle: When in use, the stator to be punched can be placed on the upper surface of the cylindrical shell 21, and then the push handle 22 can be held and the button 24 can be pressed. The button 24 will drive the limit rod 210 to move through the connecting plate 25. At the same time, the connecting plate 25 will squeeze the spring 26 until the limit rod 210 is separated from the inner wall of the groove. At this time, the push handle 22 can be pushed to drive the rotating plate 23 to rotate. At this time, the sliding rod 35 will slide on the inner wall of the through groove three 29 along the arc of the through groove one 27, so that multiple groups of clamping components can move synchronously to clamp and position the stator.

[0037] When the sliding rod 35 moves, it will drive the hinge block 31 to move. At this time, the gear 33 will also rotate accordingly. At the same time, the gear 33 meshes with the rack 37. Therefore, when the gear 33 moves, it will rotate on its own. At the same time, the gear 33 will drive the round rod 36 and the connecting rod 32 to rotate. With the cooperation of multiple groups of connecting rods 32, the clamping plate 34 will be stretched. At the same time, the connecting rod 32 and the clamping plate 34 will also rotate to adjust the position. When the clamping plate 34 contacts the stator, it will bend and fit the outer wall of the stator to ensure the stability of fixation.

[0038] After the stator is stably clamped, the button 24 can be released. At this time, the spring 26 will push the connecting plate 25 to move in the reverse direction through its own elasticity, and the limiting rod 210 will also move in the reverse direction and insert into the inner wall of the groove to limit the rotating plate 23.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
