[0001] This utility model belongs to the field of stator and rotor press-fitting technology, specifically, it relates to a stator and rotor press-fitting mechanism. Background Technology

[0002] Stator and rotor press fitting is a process in mechanical assembly, typically used to install critical components such as stators and rotors, especially in the manufacture of motors and generators. Its purpose is to press the stator and rotor together to ensure proper alignment and a tight fit. Specifically, stator and rotor press fitting involves applying precise pressure to ensure the accuracy of the fit between the stator and rotor, thereby improving the operational stability and performance of the equipment.

[0003] The existing stator and rotor pressing equipment has certain errors in the accuracy of the stator and rotor during operation, and requires manual assistance for positioning and feeding, so the work efficiency needs to be improved. Utility Model Content

[0004] To address the above deficiencies, this utility model provides a stator and rotor pressing mechanism, including a worktable, an upper positioning assembly, a lower positioning assembly, and a pressing assembly; The pressing assembly includes four guide shafts mounted on the upper surface of the worktable. A guide plate is sleeved through the four guide shafts and slides up and down along the guide shafts. A stator positioning plate is fixedly installed below the guide plate. A mounting base is also installed on the worktable. The mounting base is located on the side close to the guide shafts. A speed-regulating motor is fixedly installed at the bottom of the mounting base and located in the middle of the mounting base.

Positioning blocks I and II are evenly distributed on the worktable along the reciprocating direction of the slide plate. The fixture also includes positioning pins for engaging with positioning block I or positioning block II to ensure the slide plate position is fixed.

[0006] Furthermore, the upper positioning axis and the lower positioning axis are located on the same vertical line.

[0007] Furthermore, the upper connecting rod and the upper positioning shaft, as well as the lower connecting rod and the lower positioning shaft, are all fixed together by bolts.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example

[0015] like Figures 1 to 3 As shown, this embodiment provides a stator and rotor pressing mechanism, including a worktable 1, an upper positioning component, a lower positioning component, a pressing component, and a feeding fixture, which realizes high-precision pressing of stator and rotor, reduces the difficulty of manual production, and improves work efficiency; In detail, the press assembly includes four guide shafts 11 mounted on the upper surface of the worktable 1. A guide plate 12 is sleeved on the four guide shafts 11 and slides up and down along the guide shafts 11. A stator upper positioning plate 13 is fixedly installed below the guide plate 12. A Π-shaped mounting base 14 is also installed on the worktable 1. The mounting base 14 is located close to the guide shafts 11. A speed-regulating motor 6 is fixedly installed at the bottom of the mounting base 14 and located in the middle of the mounting base 14. A worm gear two-axis synchronous lift 15 is installed on the top of the mounting base 14. The two output ends of the worm gear two-axis synchronous lift 15 are fixedly connected to the bottom ends of the guide plate 12 respectively. In detail, the upper positioning assembly includes a top plate 21 mounted on four guide shafts 11, a cylinder II 22 mounted on the top of the top plate 21, and the output end of the cylinder II 22 is connected to the upper positioning shaft 24 via an upper connecting rod 23. In detail, the lower positioning component includes a cylinder I31 installed at the bottom of the worktable 1. The output end of the cylinder I31 is connected to the lower positioning shaft 33 through the lower connecting rod 32. The upper positioning shaft 24 and the lower positioning shaft 33 are located on the same vertical line. The upper connecting rod 23 and the upper positioning shaft 24, as well as the lower connecting rod 32 and the lower positioning shaft 33, are all fixed by bolts. The upper connecting rod 23 passes through the guide plate 12, and the guide plate 12 slides relative to the upper connecting rod 23. In detail, the loading fixture includes a slide rail 41 installed at the extension end and a slide plate 42 slidably disposed at the slide rail 41. The rotor lower positioning plate 43 is fixedly installed on the top of the slide plate 42, so that the slide plate 42 drives the rotor lower positioning plate 43 to move directly below the stator upper positioning plate 13 or move out from below the stator upper positioning plate 13, so as to facilitate subsequent loading. Positioning blocks I 44 and II 45 are evenly distributed on the worktable 1 in sequence along the reciprocating direction of the slide plate 42. It also includes positioning pins 46 for inserting with positioning blocks I 44 or II 45 to ensure the fixed position of the slide plate 42. The rotor lower positioning plate 43 is also provided with multiple evenly distributed through slots. After the stator and rotor are assembled, the bottom cover 8 and the motor housing 5 are locked together with bolts through the through slots on the rotor lower positioning plate 43.

[0016] It should be noted that when the upper connecting rod 23 moves down to locate the center point of the rotor 7, vibration may occur, affecting the accuracy of the center point alignment. Therefore, based on the actual situation, before center point positioning, the guide plate 12 is moved down to a certain height to avoid the problem of shaking when the upper connecting rod 23 drives the upper positioning shaft 24 to move down. The upper positioning shaft 24 and the lower positioning shaft 33 are replaced according to the actual rotor 7 to adapt to the positioning end of the rotor 7 to complete the center positioning, which will not be elaborated here.

[0017] Before press-fitting the stator and rotor, the stator is first installed inside the motor housing 5, and the rotor 7 is first installed together with the bottom cover 8. Then the following work is performed: First, the slide plate 42 moves to the position of the positioning block I44, and the positioning pin 46 fixes the slide plate 42 at the positioning block I44. The stator with the motor housing 5 installed is placed on the rotor lower positioning plate 43 manually. The slide plate 42 transfers the stator to the lower part of the stator upper positioning plate 13. The positioning pin 46 and the positioning block I45 fix the slide plate 42. After the worm gear two-axis synchronous lifting machine 15 works, it drives the guide plate 12 to move down. The motor housing 5 contacts the lower surface wall of the stator upper positioning plate 13. The motor housing 5 is fixed to the stator upper positioning plate 13 by bolts. Subsequently, the slide plate 42 moves the rotor lower positioning plate 43 back to the position of the positioning block I44, and places the rotor 7 with the bottom cover 8 installed on it at the rotor lower positioning plate 43. The slide plate 42 then moves the rotor 7 to the bottom of the stator. Next, cylinder II22 pushes the upper connecting rod 23 down, pushing the upper positioning shaft 24 to abut against the center position of the upper end of the rotor 7, and cylinder I31 pushes the lower connecting rod 32 up, pushing the lower positioning shaft 33 to abut against the center position of the bottom of the rotor 7, thereby achieving the purpose of center positioning of the rotor 7; Finally, the speed-regulating motor 6 drives the worm gear two-axis synchronous lifting machine 15 to push the guide plate 12 down again, completing the stator and rotor assembly.

[0018] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
