Description

Technical Field

[0001] This invention belongs to the field of motor manufacturing and processing technology, and specifically relates to a method for manufacturing a single-phase asynchronous motor. Background Technology

[0002] A single-phase asynchronous motor refers to a small-power single-phase asynchronous motor powered by a single-phase AC power supply (AC220V). Its power is designed to be relatively small, generally not exceeding 2kW. Single-phase asynchronous motors account for the majority of small-power asynchronous motors and have undergone four redesigns, meaning they have been standardized four times. Different applications have vastly different requirements for motors, thus necessitating the use of various types of motors to meet these requirements. Many existing single-phase asynchronous motors have a cylindrical body with a fixed base welded to the bottom. However, welding the fixed base to the cylindrical body is inconvenient in terms of positioning, affecting the actual weld quality.

[0003] Existing patent literature discloses a utility model patent for a single-phase asynchronous motor with overheat protection (publication number: CN208723680U). The technical solution describes a fixed base on the motor body, and based on the accompanying drawings, the motor body is also a cylindrical structure. Clearly, welding the fixed base to the cylindrical motor body presents difficulties in positioning and suffers from the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for manufacturing a single-phase asynchronous motor, addressing the shortcomings of existing technologies. The invention features a clever and reasonable structural design with strong practicality. It employs auxiliary devices to assist in the welding and assembly of the support base itself and the welding and assembly between the support base and the motor body, effectively ensuring precise positioning between various components and preventing misalignment during the welding process. This significantly improves the actual welding quality and precision, resulting in a more robust and reliable overall structure for the welded motor and extending its service life.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A method for manufacturing a single-phase asynchronous motor includes the following steps:

[0007] (1) Parts processing and preparation: Two base support plates and four reinforcing plates are prepared according to the design dimensions, and the installation positions of the reinforcing plates are marked on the base support plates according to the design requirements; positioning holes are set on the processed base support plates, which can facilitate the subsequent installation and fixing of the entire motor to the mounting surface. The installation positions of the reinforcing plates are marked on the base support plates in advance with a marking pen, which makes it easier to accurately position the reinforcing plates and the base support plates and improve the assembly accuracy.

[0008] (2) Assembly of the support base:

[0009] a. Each support base consists of a bottom support plate and two reinforcing plates. Two support bases are assembled and spliced ​​at the same time, and the two bottom support plates are placed on two auxiliary support platforms respectively. Two support bases are symmetrically installed on the motor body. Each support base consists of a bottom support plate and two reinforcing plates. The two support bases are assembled at the same time using two auxiliary support platforms, which effectively improves the actual assembly efficiency.

[0010] b. Clamping assemblies are installed on both auxiliary support platforms. Each clamping assembly includes a positioning plate, a mounting plate, and an L-shaped clamping plate. The mounting plate slides onto the positioning plate. The mounting plate has a dovetail groove, and the positioning plate has a dovetail rail. The dovetail groove matches the dovetail rail, allowing the mounting plate to slide onto the rail. The adjustable sliding design between the mounting plate and the positioning plate allows for fine-tuning of the L-shaped clamping plate's position, facilitating initial positioning adjustments between the base plate and the L-shaped clamping plate. A locking screw (or a retaining screw) further limits and fixes the mounting plate to the positioning plate. Tightening the locking screw secures the mounting plate to the positioning plate, ensuring the structural stability of the clamping assembly. Loosening the locking screw allows the mounting plate to slide relative to the positioning plate, thus changing the position of the L-shaped clamping plate. A connecting stud is installed on the L-shaped clamping plate, penetrating the mounting plate and connected to the upper and lower clamping plates. The nut secures the connecting stud to the mounting plate. Loosening the clamping nut adjusts the vertical height of the L-shaped clamping plate, while simultaneously adjusting the position of the bottom support plate on the auxiliary support platform. This ensures that the side of the bottom support plate is precisely against the vertical section of the L-shaped clamping plate, and the horizontal section of the L-shaped clamping plate is precisely against the top surface of the bottom support plate. Tightening the clamping nut then completes the initial positioning of the bottom support plate on the auxiliary support platform. After the bottom support plate is placed on the auxiliary support platform, adjusting the positions of the bottom support plate and the L-shaped clamping plate ensures that the corresponding side of the bottom support plate is precisely against the vertical section of the L-shaped clamping plate, while the top surface of the bottom support plate is pressed and fixed by the horizontal section of the L-shaped clamping plate. This effectively ensures the clamping and limiting effect of the clamping assembly on the bottom support plate. Furthermore, this design allows one side of the bottom support plate to adhere to the vertical section of the L-shaped clamping plate, facilitating the subsequent limiting of both ends of the bottom support plate by the first and second limiting plates.

[0011] c. Adjust the positions of limiting plate one and limiting plate two. Both limiting plate one and limiting plate two are slidably engaged between the two auxiliary support platforms, and are symmetrically distributed along the length of the auxiliary support platforms. Both limiting plate one and limiting plate two are connected to the horizontal adjustment component. Adjust the horizontal adjustment component so that limiting plate one and limiting plate two move towards each other along the length of the auxiliary support platforms until they abut and are limited at both ends of the bottom support plate. Both ends of limiting plate one and limiting plate two are provided with fitting grooves that match the auxiliary support platforms, allowing limiting plate one and limiting plate two to engage between the two auxiliary support platforms and move horizontally along the length of the auxiliary support platforms. The horizontal adjustment component is set along the length of the auxiliary support platform. The limiting plate 1 and the limiting plate 2 move towards each other simultaneously. When the limiting plate 1 and the limiting plate 2 are both limited and abut against the corresponding end face of the bottom support plate, the bottom support plate is located at the center of the auxiliary support platform. The center line of the length of the bottom support plate is on the same plane as the center line of the length of the auxiliary support platform. When the limiting plate 1 and the limiting plate 2 push the bottom support plate to move horizontally, the bottom support plate is always attached to the vertical section of the L-shaped clamping plate, which further ensures the stability and horizontality during adjustment. This is more conducive to the accuracy and reliability of actual adjustment. The bottom support plate is limited and fixed by the L-shaped clamping plate, the limiting plate 1, and the limiting plate 2, which effectively ensures the firmness of the bottom support plate on the auxiliary support platform.

[0012] d. Place the reinforcing plate. According to the marked position on the bottom support plate, place the reinforcing plate on the bottom support plate and clamp and fix the reinforcing plate with the positioning component. According to the marking, accurately position the reinforcing plate and the bottom support plate and clamp and fix the positioned reinforcing plate with the positioning component. This will prevent the bottom support plate and the reinforcing plate from shifting during the welding operation, effectively improve the welding accuracy between the two, and thus ensure the structural strength of the assembled support.

[0013] e. Welding equipment is used to weld and fix the contact surfaces of the reinforcing plate and the bottom support plate. Welding fixation is used to fix the reinforcing plate and the bottom support plate, which effectively ensures the overall structural strength of the support base, ensures the reinforcement support of the support base and the entire motor, makes the structure of the entire motor more robust and reliable, the operation of the motor more stable, and extends its service life.

[0014] Since the two support bases are assembled and welded on the two auxiliary support platforms, the top surfaces of the two auxiliary support platforms are at the same height. At the same time, the two ends of the two bottom support plates are limited by the first limiting plate and the second limiting plate to ensure the precise positioning of the two support bases. The corresponding end faces of the two support bases are flush and the two support bases are at the same installation height, which facilitates the subsequent positioning and installation between the two support bases and the motor body, ensures the symmetrical installation of the support bases on both sides of the motor body, and ensures the overall structural balance and stability of the assembled motor.

[0015] (3) Assembly of the support base and the motor body:

[0016] a. Place the motor body on the main support platform. Two auxiliary support platforms are symmetrically arranged on both sides of the main support platform. Support brackets are installed on the main support platform. Place the motor body on the support brackets, ensuring the motor shaft is precisely engaged in the limiting slot of limiting plate one, with the front end of the motor body abutting against the side of limiting plate one. The rear end of the motor body is supported within the arc-shaped bracket of limiting plate two, with the rear end of the motor body abutting against the side of limiting plate two. The motor body's body is positioned precisely between limiting plate one and limiting plate two. After welding and assembling the two support bases, simultaneously position the motor body relative to both support bases. The motor body is located... On the main support platform, the support bracket, designed in conjunction with the cylindrical structure of the motor body, supports and lifts the bottom of the motor body. Limiting plates one and two further position and support the two ends of the motor body. The limiting slot on limiting plate one supports and lifts the motor shaft of the motor body, while the arc-shaped bracket on limiting plate two provides auxiliary support to the tail end of the motor body. This effectively ensures the stability and reliability of the motor body on the column support platform. Limiting plates one and two also abut against and limit the two ends of the motor body, ensuring that the two ends of the body are aligned with the two ends of the support base, achieving precise positioning of the support base and the motor body.

[0017] b. Adjust the top pressure component to press and fix the top of the motor body; after the motor body is firmly placed on the main support platform, the top pressure component presses and fixes the motor body, effectively ensuring the firmness and reliability of the motor body on the main support platform, thereby facilitating the precise positioning and welding operation between the support base and the motor body, ensuring that the motor body will not shift during positioning adjustment and welding operations, and facilitating actual operation.

[0018] c. Adjust the positioning component to completely disassemble and separate the positioning component from the reinforcing plate, so as to facilitate the subsequent movement and adjustment of the support base towards the motor body.

[0019] d. Move the support base towards the motor body until the arc-shaped end face of the reinforcing plate is in contact with the side of the motor body; the surface of the reinforcing plate that contacts the motor body is an arc-shaped end face, thereby ensuring the contact area between the reinforcing plate and the motor body, improving the welding firmness and reliability between the support base and the motor body, and making the structure of the assembled motor more stable and reliable.

[0020] e. Welding equipment is used to weld and fix the contact surface between the reinforcing plate and the motor body; the welding fixation between the reinforcing plate and the motor body effectively ensures the firmness of the connection between the two and extends the service life of the entire motor.

[0021] f. Remove the welded and assembled motor.

[0022] Furthermore, in step b of step (2), the adjustment steps of the horizontal adjustment component are as follows:

[0023] ① The horizontal adjustment assembly includes an adjustment motor, a guide screw, and a guide slide. The adjustment motor is connected to the guide screw. The guide screw and guide slide are located on the sides of two auxiliary support platforms. Guide slider 1 is provided on both sides of limit plate 1, and guide slider 2 is provided on both sides of limit plate 2. Guide slider 1 and guide slider 2 on the same side as the guide screw are threaded onto the guide slide. The guide screw has threaded sections 1 and 2 with opposite thread directions. Guide slider 1 and guide slider 2 threaded onto the guide screw are located on threaded sections 1 and 2 respectively. On threaded section two, guide slider one and guide slider two, on the same side as the guide slide rod, are slidably fitted onto the guide slide rod. The structure is cleverly and reasonably designed. Limiting plate one is connected between the guide slide rod and the guide screw through guide slider one, and limiting plate two is connected between the guide slide rod and the guide screw through guide slider two. Adjusting the motor drives the guide screw to rotate, and in conjunction with the design of threaded section one and threaded section two, limiting plate one and limiting plate two can move towards or away from each other at the same time, thereby realizing the clamping and limiting or releasing of the bottom support plate by limiting plate one and limiting plate two. It is convenient and simple to use and operate.

[0024] ② The adjustment motor starts and drives the guide screw to rotate. The rotation of the guide screw causes the guide slider one on thread section one and the guide slider two on thread section two to move towards each other. The guide slider one drives the limit plate one fixed to it to move, and the guide slider two drives the limit plate two fixed to it to move. At the same time, the limit plates one and two are always guided and limited by the guide slide rod when they move, until the limit plates one and two are both limited and attached to the corresponding ends of the bottom support plate. The adjustment motor drives the guide screw to rotate, causing the limit plates one and two to move towards each other, until the limit plates one and two abut against the corresponding ends of the bottom support plate, realizing the limitation and fixation of the bottom support plate. During the movement of the limit plates one and two, one side is limited by the guide screw and the other side is guided and limited by the guide slide rod, which effectively ensures the balance and stability of the movement adjustment of the limit plates one and two, and improves the operational safety performance.

[0025] Furthermore, in step b of step (3), the adjustment steps of the top pressure assembly are as follows:

[0026] ① The top-pressure assembly includes a vertical support, an adjusting plate, and a top-pressure plate. A guide rod is provided on the side of the main support platform. The vertical support slides onto the guide rod and is fixed in place by a set screw. One end of the adjusting plate is movably sleeved onto a guide post at the top of the vertical support. A limit nut is provided at the end of the guide post. An expansion plate is provided at the other end of the adjusting plate. The expansion plate and the adjusting plate are integrally formed, ensuring overall structural strength. An adjusting screw is threaded through the expansion plate, and an operating handle is provided at the top of the adjusting screw. The operating handle is designed for ease of adjustment. A mounting bearing is provided on the top-pressure plate, and the bottom end of the adjusting screw is connected to the mounting bearing. The structure is compact and reasonable, and the operation is simple. This top-pressure assembly ensures... The top-pressing assembly ensures a secure and stable fit of the motor body on the main support platform. It also allows for quick tightening or loosening of the top of the motor body. An adjusting plate, fitted onto a guide post, rotates around the guide post to adjust its angle, allowing the top-pressing plate to be rotated to or off the main support platform as needed. An adjusting screw is threaded onto an expansion plate, with its bottom end connected to a mounting bearing on the top-pressing plate. This bearing connects the adjusting screw to the top-pressing plate without affecting its rotation. Rotating the adjusting screw adjusts the length of its extension beyond the expansion plate, thus adjusting the height of the top-pressing plate and enabling the tightening or loosening of the motor body.

[0027] ② Loosen the limit nut and rotate the adjusting plate along the guide column. The adjusting plate will drive the top pressure plate to rotate synchronously until the top pressure plate is rotated and adjusted above the motor body. Loosen the limit nut and rotate the adjusting plate to rotate the top pressure plate above the motor body to facilitate the subsequent pressing operation of the top pressure plate on the motor body.

[0028] ③ Turn the adjusting screw downwards. The adjusting screw will drive the top pressure plate to move downwards synchronously until the top pressure plate is matched and locked on the top of the motor body, and the top pressure plate and the top of the motor body are pressed together. Then tighten the limit nut. The adjusting screw will drive the top pressure plate to move downwards to ensure the pressing effect of the top pressure plate on the motor body.

[0029] Furthermore, each of the two auxiliary support platforms is equipped with two positioning components, which are respectively installed on limit plate one and limit plate two. Each positioning component includes a positioning rod and a positioning frame. The positioning frame is located at one end of the positioning rod and has a positioning slot that matches the reinforcing plate. A second clamping screw is provided on the side of the positioning frame. The reinforcing plate is inserted into the positioning slot, and the clamping screw secures the reinforcing plate to the positioning frame. An adjusting groove is provided on the positioning rod. Both sides of limit plate one and limit plate two have locking slots. The positioning rod slides into the locking slots, and limit posts are provided within the locking slots to limit movement. The column matches the adjusting slide, and the limiting column is engaged in the adjusting slide. The end of the limiting column is equipped with a fastening nut. The positioning rod moves along the embedded groove, while the adjusting slide is always guided and limited by the limiting column, effectively ensuring the stability and levelness of the positioning rod's movement adjustment. The structure is compact and reasonable. Each auxiliary support platform is equipped with two positioning components, which are respectively installed on limiting plate one and limiting plate two. The two positioning components can simultaneously position and clamp the two reinforcing plates, thereby achieving precise positioning of the two reinforcing plates and the bottom support plate. Simultaneous positioning of the two reinforcing plates can accelerate the actual assembly accuracy of the support base.

[0030] Furthermore, in step d of step (2), the placement of the reinforcing plate is as follows:

[0031] ① Insert the reinforcing plate into the positioning slot of the positioning frame, and move and adjust the reinforcing plate along the positioning slot until the horizontal end of the reinforcing plate is supported on the corresponding bottom support plate. Then tighten the second clamping screw to limit and fix the reinforcing plate and the positioning frame. The positioning slot realizes the initial insertion of the reinforcing plate and the positioning frame. Move the reinforcing plate along the positioning slot so that the horizontal bottom end of the reinforcing plate contacts the bottom support plate. Then tighten the second clamping screw to further limit and fix the reinforcing plate and the positioning frame, ensuring the installation firmness between the reinforcing plate and the positioning component, so as to facilitate the subsequent adjustment operation of the reinforcing plate position through the positioning component.

[0032] ② Loosen the fastening nut and move the positioning rod along the limiting post and the locking groove. The positioning rod drives the reinforcing plate to move synchronously. At the same time, loosen the first locking screw and adjust the position of the bottom support plate until the reinforcing plate is accurately positioned at the corresponding mark on the bottom support plate. Then tighten the fastening nut and the first locking screw. The positioning rod itself is guided and limited by the locking groove. At the same time, the adjusting groove on the positioning rod cooperates with the limiting post, so that the positioning rod is synchronously guided by the locking groove and the limiting post during movement. This effectively ensures the stability and levelness of the positioning rod during the movement and adjustment process. At the same time, during the adjustment of the reinforcing plate position, the fine adjustment of the bottom support plate makes the reinforcing plate move to the set position, thereby achieving precise positioning between the reinforcing plate and the positioning plate and improving the welding accuracy and welding quality of the support seat.

[0033] Furthermore, in step c of step (3), the adjustment steps of the positioning component are as follows: loosen the second tightening screw and the fastening nut, move the positioning rod along the limiting post and the embedded slot, the positioning rod drives the positioning frame to move synchronously until the reinforcing plate is completely separated from the positioning slot of the corresponding positioning frame, and then tighten the fastening nut; after the reinforcing plate and the bottom support plate are welded, the positioning frame is completely separated from the reinforcing plate, so as to facilitate the subsequent movement of the support base and realize the accurate positioning between the support base and the motor body.

[0034] Furthermore, in step d of step (3), the movement steps of the support base are as follows:

[0035] ① Each clamping assembly is connected to a corresponding pushing assembly. The pushing assembly includes a pushing cylinder and a pushing support plate. A guide slot is provided through the center of the auxiliary support platform along the width direction. The pushing support plate is slidably limited in the guide slot. The top surface of the pushing support plate is flush with the top surface of the auxiliary support platform. A positioning plate is fixedly installed on the pushing support plate. The piston rod end of the pushing cylinder is connected to the positioning plate. The pushing assembly pushes the clamping assembly to move, thereby realizing the overall movement of the support base. The support base is moved to a position that is precisely aligned with the motor body. The design is reasonable and the operation is automated.

[0036] ② When the push cylinder is activated, the piston rod extends, pushing the positioning plate towards the motor body. The movement of the positioning plate causes the mounting plate, which is fixed to it, to move synchronously. The movement of the mounting plate causes the L-shaped clamping plate to move synchronously, which in turn pushes the bottom support plate to move synchronously. Since the positioning plate and the push support plate are fixedly installed, the push support plate always moves synchronously with the positioning plate, ensuring that it continuously supports and lifts the bottom of the support base until the curved end face of the reinforcing plate is in contact with the side of the motor body. The push cylinder then pushes the positioning plate, thus clamping the components. The entire structure moves while the side of the bottom support plate contacts the vertical section of the L-shaped clamping plate, so that the movement of the clamping assembly pushes the bottom support plate to move synchronously, thus moving the support seat. The positioning plate is fixed to the top push support plate, so that the movement of the positioning plate pushes the top push support plate to move synchronously. The top push support plate is set at the center of the auxiliary support platform. The top push support plate and the auxiliary support platform are supported together on the bottom surface of the bottom support plate. When the top push support plate moves synchronously with the support seat, the top push support plate always supports and lifts the support seat, making the entire movement and adjustment process more reasonable and convenient, and the entire movement and adjustment is automated.

[0037] ③ Auxiliary support plates are set on both sides of the main support platform. The top surface of the auxiliary support plate is level with the bottom surface of the guide slot. When the push cylinder pushes the push support plate towards the motor body, the push support plate gradually moves and supports itself on the auxiliary support plate. During the movement, the push support plate will gradually move and support itself on the corresponding auxiliary support plate. The auxiliary support plate provides auxiliary support and reinforcement for the push support plate, making the entire movement and adjustment process more stable and safe.

[0038] Furthermore, in step f of step (3), the motor removal step is as follows:

[0039] ① Turn the adjusting screw upwards. The adjusting screw will cause the top plate to move up until the top plate is completely separated from the motor body. Then loosen the limit nut and turn the adjusting plate and the top plate completely out from above the motor body.

[0040] ② Loosen the clamping nut and move the L-shaped clamping plate upwards until the horizontal section of the L-shaped clamping plate moves away from the top surface of the bottom support plate and the vertical section of the L-shaped clamping plate moves away from the side of the bottom support plate.

[0041] ③ The top-pushing cylinder is started, and the piston rod retracts, driving the clamping assembly to move away from the motor body until the clamping assembly is completely removed from above the bottom support plate;

[0042] ④ Activate the horizontal adjustment component and move the first and second limit plates in opposite directions along the length of the auxiliary support platform until the first and second limit plates drive the positioning component to be completely removed from the bottom support plate.

[0043] ⑤ Remove the motor body from the main support platform; during the entire removal process, completely remove the top pressing component from the motor body, and the pushing component drives the clamping component to move and reset, so that the clamping component is completely removed from the bottom support plate. Then, start the horizontal adjustment component to move the first and second limit plates in opposite directions, release the two ends of the bottom support plate, and then take out the entire assembled motor. The design is reasonable, the process is clean and easy to operate.

[0044] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0045] This invention features a clever and reasonable structural design, strong practicality, clear principles, easy real-time operation, and general control requirements, making it easy to promote. It employs auxiliary devices to assist in the welding and assembly of the support base itself and the welding and assembly between the support base and the motor body, effectively ensuring the precise positioning of each component and preventing misalignment or displacement of components during the welding process. This effectively improves the actual welding quality and precision, resulting in a more robust and reliable overall structure of the welded motor and extending its service life.

Detailed Implementation

[0064] like Figures 1 to 16 The diagram illustrates a method for manufacturing a single-phase asynchronous motor according to the present invention, comprising the following steps:

[0065] (1) Parts processing and preparation: Two base support plates 3 and four reinforcing plates 4 are prepared according to the design dimensions, and the installation positions of the reinforcing plates 4 are marked on the base support plates 3 according to the design requirements; the base support plates 3 are provided with positioning holes 55, which can facilitate the subsequent installation and fixing of the entire motor to the mounting surface. The installation positions of the reinforcing plates 4 are marked on the base support plates 3 in advance with a marking pen, which makes it easier to accurately position the reinforcing plates 4 and the base support plates 3, and improves the assembly accuracy.

[0066] (2) Assembly of support base 2:

[0067] a. Each support base 2 consists of a bottom support plate 3 and two reinforcing plates 4. Two support bases 2 are assembled and spliced ​​at the same time, and the two bottom support plates 3 are placed on two auxiliary support platforms 7 respectively. Two support bases 2 are symmetrically installed on the motor body 1. Each support base 2 consists of a bottom support plate 3 and two reinforcing plates 4. The two support bases 2 are assembled at the same time using two auxiliary support platforms 7, which effectively improves the actual assembly efficiency.

[0068] b. Each of the two auxiliary support platforms 7 is equipped with a clamping assembly 8, which includes a positioning plate 9, a mounting plate 10, and an L-shaped clamping plate 11. The mounting plate 10 is slidably engaged with the positioning plate 9. The mounting plate 10 is provided with a dovetail groove 56, and the positioning plate 9 is provided with a dovetail slide rail 57. The dovetail groove 56 matches the dovetail slide rail 57. The mounting plate 10 is slidably engaged with the dovetail slide rail 57 through the dovetail groove 56. The adjustable sliding design between the mounting plate 10 and the positioning plate 9 allows for adjustment of the position of the L-shaped clamping plate 11. Fine-tuning is performed to facilitate the initial positioning adjustment between the base plate 3 and the L-shaped clamping plate 11. The mounting plate 10 and the positioning plate 9 are then fixed in place by the first tightening screw 12. Tightening the first tightening screw 12 secures the mounting plate 10 and the positioning plate 9, ensuring the structural stability of the clamping assembly 8. Loosening the first tightening screw 12 allows the mounting plate 10 to slide relative to the positioning plate 9, thereby changing the position of the L-shaped clamping plate 11. The L-shaped clamping plate 11 is equipped with a connecting stud 13 that penetrates the mounting plate 10. The connecting stud 13 is fixed to the mounting plate 10 by two clamping nuts 14. Loosening the clamping nuts 14 adjusts the vertical height of the L-shaped clamping plate 11, and simultaneously adjusts the position of the bottom support plate 3 on the auxiliary support platform 7, so that the side of the bottom support plate 3 is precisely against the vertical section of the L-shaped clamping plate 11, and the horizontal section of the L-shaped clamping plate 11 is precisely against the top surface of the bottom support plate 3. Then tighten the clamping nuts 14. The clamping assembly 8 achieves the initial positioning of the bottom support plate 3 on the auxiliary support platform 7. After the support plate 3 is placed on the auxiliary support platform 7, by adjusting the position of the bottom support plate 3 and the L-shaped clamping plate 11, the corresponding side of the bottom support plate 3 is exactly abutted against and limited on the vertical section of the L-shaped clamping plate 11, while the top surface of the bottom support plate 3 is pressed and fixed by the horizontal section of the L-shaped clamping plate 11, effectively ensuring the pressing and limiting effect of the clamping assembly 8 on the bottom support plate 3. Moreover, this design allows one side of the bottom support plate 3 to be attached to the vertical section of the L-shaped clamping plate 11, which facilitates the subsequent limiting of the two ends of the bottom support plate 3 by the limiting plate 15 and the limiting plate 2 16.

[0069] c. Adjust the positions of limiting plate 15 and limiting plate 2. Both limiting plate 15 and limiting plate 2 are slidably engaged between the two auxiliary support platforms 7, and are symmetrically distributed along the length of the auxiliary support platform 7. Both limiting plate 15 and limiting plate 2 are connected to the horizontal adjustment component 17. Adjust the horizontal adjustment component 17 so that limiting plate 15 and limiting plate 2 move towards each other along the length of the auxiliary support platform 7 until both limiting plate 15 and limiting plate 2 abut against and are limited at both ends of the bottom support plate 3. Both ends of limiting plate 15 and limiting plate 2 are provided with a fitting groove 58, which matches the auxiliary support platform 7, so that limiting plate 15 and limiting plate 2 are matched and engaged between the two auxiliary support platforms 7, and move horizontally along the length of the auxiliary support platform 7. 15. Limiting plate 2 16 is set along the length of the auxiliary support platform 7. The horizontal adjustment component 17 drives limiting plate 15 and limiting plate 2 16 to move towards each other simultaneously. When limiting plate 15 and limiting plate 2 16 are both limited and abut against the corresponding end face of the bottom support plate 3, the bottom support plate 3 is located at the center of the auxiliary support platform 7. The center line of the length direction of the bottom support plate 3 is on the same plane as the center line of the length direction of the auxiliary support platform 7. When limiting plate 15 and limiting plate 2 16 push the bottom support plate 3 to move horizontally, the bottom support plate 3 is always attached to the vertical section of the L-shaped clamping plate 11, which further ensures the stability and horizontality during adjustment and is more conducive to the accuracy and reliability of actual adjustment. The bottom support plate 3 is limited and fixed by the L-shaped clamping plate 11, limiting plate 15, and limiting plate 2 16, which effectively ensures the firmness of the bottom support plate 3 on the auxiliary support platform 7.

[0070] The adjustment steps for the horizontal adjustment component 17 are as follows:

[0071] ① The horizontal adjustment assembly 17 includes an adjustment motor 24, a guide screw 25, and a guide slide 26. The adjustment motor 24 is connected to the guide screw 25. The guide screw 25 and the guide slide 26 are located on the sides of the two auxiliary support platforms 7. Guide sliders 27 are provided on both sides of the limiting plate 15, and guide sliders 28 are provided on both sides of the limiting plate 16. The guide sliders 27 and 28 on the same side as the guide screw 25 are threaded onto the guide slide 26. The guide screw 25 is provided with threaded sections 29 and 30 with opposite thread directions. The guide sliders 27 and 28 threaded onto the guide screw 25 are located on the threaded sections 29 and 30 respectively. On threaded section 29 and threaded section 30, guide slider 1 27 and guide slider 28 on the same side as guide slide rod 26 are slidably sleeved on guide slide rod 26; the structural design is ingenious and reasonable. Limiting plate 15 is connected between guide slide rod 26 and guide screw 25 through guide slider 1 27, and limiting plate 26 is connected between guide slide rod 26 and guide screw 25 through guide slider 28. Adjusting motor 24 drives guide screw 25 to rotate, and with the design of threaded section 29 and threaded section 30, limiting plate 15 and limiting plate 26 can move towards or away from each other at the same time, thereby realizing the clamping and limiting or releasing of limiting plate 15 and limiting plate 26 on bottom support plate 3. It is convenient and simple to use and operate.

[0072] ② The adjustment motor 24 starts and drives the guide screw 25 to rotate. The rotation of the guide screw 25 causes the guide slider 27 on the first thread section 29 and the guide slider 28 on the second thread section 30 to move towards each other. The guide slider 27 drives the fixed limiting plate 15 to move, and the guide slider 28 drives the fixed limiting plate 16 to move. At the same time, the limiting plates 15 and 16 are always guided and restricted by the guide rod 26 when they move, until the limiting plates 15 and 16 are both fixed and attached to the bottom support plate 3. At the corresponding ends, the adjusting motor 24 drives the guide screw 25 to rotate, causing the first limiting plate 15 and the second limiting plate 16 to move towards each other until the first limiting plate 15 and the second limiting plate 16 abut against the corresponding ends of the bottom support plate 3, thereby limiting and fixing the bottom support plate 3. During the movement of the first limiting plate 15 and the second limiting plate 16, one side is limited by the guide screw 25, and the other side is guided and limited by the guide slide rod 26, effectively ensuring the balance and stability of the movement adjustment of the first limiting plate 15 and the second limiting plate 16, and improving the operational safety performance.

[0073] d. Place the reinforcing plate 4. According to the marked position on the bottom support plate 3, place the reinforcing plate 4 on the bottom support plate 3 and clamp and fix the reinforcing plate 4 with the positioning component 23. According to the marking, accurately position the reinforcing plate 4 and the bottom support plate 3, and clamp and fix the positioned reinforcing plate 4 with the positioning component 23. This ensures that the bottom support plate 3 and the reinforcing plate 4 will not shift during the welding operation, effectively improving the welding accuracy between the two, thereby ensuring the structural strength of the assembled support base 2.

[0074] Two positioning components 23 are provided on each of the two auxiliary support platforms 7. The two positioning components 23 are respectively installed on the first limiting plate 15 and the second limiting plate 16. The positioning component 23 includes a positioning rod 42 and a positioning frame 43. The positioning frame 43 is located at one end of the positioning rod 42. The positioning frame 43 is provided with a positioning slot 44, which matches the reinforcing plate 4. The side of the positioning frame 43 is provided with a second clamping screw 45. The reinforcing plate 4 is inserted into the positioning slot 44 and then the reinforcing plate 4 and the positioning frame 43 are clamped and fixed by the second clamping screw 45. The positioning rod 42 is provided with an adjusting groove 46. The two sides of the first limiting plate 15 and the two sides of the second limiting plate 16 are provided with a locking groove 47. The positioning rod 42 is slidably locked in the locking groove 47. The locking groove 47 is provided with a limiting post 48, which matches the adjusting groove 46. The limiting post 48 is locked in the adjusting groove 46. The slide groove 46 is located inside the slide groove 46, and the end of the limiting post 48 is provided with a fastening nut 49. The positioning rod 42 moves along the embedded slot 47, while the adjusting slide groove 46 is always guided and limited by the limiting post 48, which effectively ensures the stability and horizontality of the movement adjustment of the positioning rod 42. The structure is compact and reasonable. Each auxiliary support platform 7 is provided with two positioning components 23. The two positioning components 23 are respectively installed on the first limiting plate 15 and the second limiting plate 16. The two positioning components 23 can simultaneously position and clamp the two reinforcing plates 4, thereby achieving accurate positioning of the two reinforcing plates 4 and the bottom support plate 3. Simultaneous positioning of the two reinforcing plates 4 can speed up the actual assembly accuracy of the support base 2. The first limiting plate 15 and the second limiting plate 16 are both provided with brackets, which provide auxiliary support and reinforcement for the positioning rod 42, making the movement adjustment of the entire positioning component 23 more stable and reliable.

[0075] The installation steps for reinforcing plate 4 are as follows:

[0076] ① Insert the reinforcing plate 4 into the positioning slot 44 of the positioning frame 43, and move and adjust the reinforcing plate 4 along the positioning slot 44 until the horizontal end of the reinforcing plate 4 is placed on the corresponding bottom support plate 3. Then tighten the second clamping screw 45 to limit and fix the reinforcing plate 4 and the positioning frame 43. The positioning slot 44 realizes the initial insertion of the reinforcing plate 4 and the positioning frame 43. Move the reinforcing plate 4 along the positioning slot 44 so that the horizontal bottom end of the reinforcing plate 4 contacts the bottom support plate 3. Then tighten the second clamping screw 45 to further limit and fix the reinforcing plate 4 and the positioning frame 43, ensuring the installation firmness between the reinforcing plate 4 and the positioning component 23, so as to facilitate the subsequent adjustment operation of the position of the reinforcing plate 4 through the positioning component 23.

[0077] ② Loosen the fastening nut 49 and move the positioning rod 42 along the limiting post 48 and the locking groove 47. The positioning rod 42 drives the reinforcing plate 4 to move synchronously. At the same time, loosen the locking screw 12 and adjust the position of the bottom support plate 3 until the reinforcing plate 4 is accurately positioned at the corresponding mark position on the bottom support plate 3. Then tighten the fastening nut 49 and the locking screw 12. The positioning rod 42 itself is guided and limited by the locking groove 47. At the same time, the adjusting slide 46 on the positioning rod 42 cooperates with the limiting post 48, so that the positioning rod 42 is synchronously guided by the locking groove 47 and the limiting post 48 during movement. This effectively ensures the stability and levelness of the positioning rod 42 during the movement and adjustment process. At the same time, during the adjustment of the position of the reinforcing plate 4, the bottom support plate 3 is finely adjusted to move the reinforcing plate 4 to the set position, thereby achieving precise positioning between the reinforcing plate 4 and the positioning plate 9 and improving the welding accuracy and welding quality of the support 2.

[0078] e. Welding equipment is used to weld and fix the contact surfaces of the reinforcing plate 4 and the bottom support plate 3. Welding fixation is used to fix the reinforcing plate 4 and the bottom support plate 3, which effectively ensures the overall structural strength of the support base 2, ensures the reinforcement support of the support base 2 and the entire motor, makes the structure of the entire motor more robust and reliable, the operation of the motor more stable, and extends its service life.

[0079] Since the two support bases 2 are assembled and welded on the two auxiliary support platforms 7, the top surfaces of the two auxiliary support platforms 7 are at the same height, and the two ends of the two bottom support plates 3 are limited by the limiting plate 15 and the limiting plate 2 16, ensuring the precise positioning of the two support bases 2. The corresponding end faces of the two support bases 2 are flush, and the two support bases 2 are at the same installation height, which facilitates the subsequent positioning and installation between the two support bases 2 and the motor body 1, ensuring the symmetrical installation of the support bases 2 on both sides of the motor body 1, and ensuring the overall structural balance and stability of the assembled motor.

[0080] (3) Assembly of support base 2 and motor body 1:

[0081] a. Place the motor body 1 on the main support platform 18. Two auxiliary support platforms 7 are symmetrically arranged on both sides of the main support platform 18. The main support platform 18 is equipped with a support bracket 19. Place the motor body 1 on the support bracket 19. At the same time, the motor shaft 5 of the motor body 1 is precisely locked into the limiting slot 20 of the limiting plate 15, and the front end of the motor body 1 abuts against the side of the limiting plate 15. The rear end of the motor body 1 is supported in the arc-shaped bracket 21 of the limiting plate 26, and the rear end of the motor body 1 abuts against the side of the limiting plate 26. The body 6 of the motor body 1 is located precisely between the limiting plate 15 and the limiting plate 26. After the two support seats 2 are welded and assembled, simultaneously position the two support seats 2 and the motor body 1. Located on the main support platform 18, the support bracket 19, in conjunction with the cylindrical structure of the motor body 1, supports and lifts the bottom surface of the motor body 1. The first limiting plate 15 and the second limiting plate 16 further position and support the two ends of the body 6 of the motor body 1. The limiting slot 20 on the first limiting plate 15 supports and lifts the motor shaft 5 of the motor body 1. The arc-shaped bracket 21 on the second limiting plate 16 provides auxiliary support to the tail end of the motor body 1, effectively ensuring the firmness and reliability of the placement of the motor body 1 on the column support platform. The first limiting plate 15 and the second limiting plate 16 are exactly in contact with the two ends of the body 6 of the motor body 1 to limit the movement, thereby ensuring that the two ends of the body 6 are exactly aligned with the two ends of the support seat 2, achieving precise positioning of the support seat 2 and the motor body 1.

[0082] b. Adjust the top pressing component 22 to press and fix the top of the motor body 1; after the motor body 1 is firmly placed on the main support platform 18, the top pressing component 22 presses and fixes the motor body 1, effectively ensuring the firmness and reliability of the placement of the motor body 1 on the main support platform 18, thereby facilitating the precise positioning and welding operation between the support base 2 and the motor body 1, ensuring that the motor body 1 will not shift during positioning adjustment and welding operations, and facilitating actual operation;

[0083] The adjustment steps for the top pressure assembly 22 are as follows:

[0084] ① The top pressure assembly 22 includes a vertical support rod 31, an adjusting plate 32, and a top pressure plate 33. A guide rod 34 is provided on the side of the main support platform 18. The vertical support rod 31 is slidably engaged with the guide rod 34, and the vertical support rod 31 and the guide rod 34 are fixed and limited by a set screw 35. One end of the adjusting plate 32 is movably sleeved on the guide post 36 at the top of the vertical support rod 31. A limit nut 37 is provided at the end of the guide post 36. The other end of the adjusting plate 32 is provided with an expansion plate 38. The expansion plate 38 and the adjusting plate 32 are integrally formed, resulting in a strong overall structure. An adjusting screw 39 is threaded through the expansion plate 38. An operating handle 40 is provided at the top of the adjusting screw 39. The operating handle 40 is designed for greater user convenience, facilitating the rotation and adjustment of the adjusting screw 39. A mounting bearing 41 is provided on the top pressure plate 33, and the bottom end of the adjusting screw 39 is connected to the mounting bearing 41. The structure is compact and reasonable, and the operation is simple. The top-pressing assembly 22 ensures the pressing and fixing effect on the motor body 1, effectively ensuring the firmness and reliability of the motor body 1 on the main support platform 18. Moreover, the top-pressing assembly 22 can realize the quick pressing or loosening adjustment of the top of the motor body 1. The adjusting plate 32 is sleeved on the guide column 36, so that the adjusting plate 32 can rotate around the guide column 36 as the axis, thereby rotating the top-pressing plate 33 to or out of the main support platform 18 as needed. The adjusting screw 39 is threaded onto the expansion plate 38, and its bottom end is connected to the mounting bearing 41 on the top-pressing plate 33. The mounting bearing 41 realizes the connection between the adjusting screw 39 and the top-pressing plate 33, while not affecting the rotation of the adjusting screw 39. Rotating the adjusting screw 39 can adjust the length of the adjusting screw 39 extending out of the expansion plate 38, thereby realizing the adjustment of the height of the top-pressing plate 33, realizing the pressing or loosening operation of the top-pressing plate 33 on the motor body 1.

[0085] ② Loosen the limit nut 37, rotate the adjusting plate 32 along the guide post 36, and the adjusting plate 32 drives the top pressure plate 33 to rotate synchronously until the top pressure plate 33 is rotated and adjusted above the motor body 1; loosen the limit nut 37, rotate the adjusting plate 32 to rotate the top pressure plate 33 above the motor body 1, so as to facilitate the subsequent pressing operation of the top pressure plate 33 on the motor body 1.

[0086] ③ Rotate the adjusting screw 39 downwards. The adjusting screw 39 drives the top pressure plate 33 to move downwards synchronously until the top pressure plate 33 is matched and locked on the top of the motor body 1, and the top pressure plate 33 is pressed against the top of the motor body 1. Then tighten the limit nut 37. The adjusting screw 39 drives the top pressure plate 33 to move downwards to ensure the pressing effect of the top pressure plate 33 on the motor body 1.

[0087] c. Adjust the positioning component 23 so that the positioning component 23 and the reinforcing plate 4 are completely disassembled and separated, so that the positioning component 23 and the reinforcing plate 4 can be separated to facilitate the subsequent movement and adjustment of the support base 2 towards the motor body 1.

[0088] The adjustment steps of the positioning component 23 are as follows: loosen the tightening screw 45 and the fastening nut 49, move the positioning rod 42 along the limiting post 48 and the embedded slot 47, the positioning rod 42 drives the positioning frame 43 to move synchronously until the reinforcing plate 4 is completely disengaged from the positioning slot 44 of the corresponding positioning frame 43, and then tighten the fastening nut 49; after the reinforcing plate 4 is welded to the bottom support plate 3, completely separate the positioning frame 43 from the reinforcing plate 4, so as to facilitate the subsequent movement of the support base 2 and realize the precise positioning between the support base 2 and the motor body 1;

[0089] d. Move the support seat 2 towards the motor body 1 until the arc-shaped end face of the reinforcing plate 4 is in contact with the side of the motor body 1; the surface of the reinforcing plate 4 that contacts the motor body 1 is an arc-shaped end face, thereby ensuring the contact area between the reinforcing plate 4 and the motor body 1, improving the welding firmness and reliability between the support seat 2 and the motor body 1, and making the structure of the assembled motor more stable and reliable.

[0090] The steps for moving support 2 are as follows:

[0091] ① Each clamping assembly 8 is connected to a corresponding pushing assembly 53. The pushing assembly 53 includes a pushing cylinder 50 and a pushing support plate 51. A guide slot 52 is provided through the center of the auxiliary support platform 7 along the width direction. The pushing support plate 51 is slidably limited in the guide slot 52. The top surface of the pushing support plate 51 is flush with the top surface of the auxiliary support platform 7. The positioning plate 9 is fixedly installed on the pushing support plate 51. The piston rod end of the pushing cylinder 50 is connected to the positioning plate 9. The pushing assembly 53 pushes the clamping assembly 8 to move, thereby realizing the overall movement of the support seat 2 and moving the support seat 2 to be precisely positioned with the motor body 1. The design is reasonable and the operation is automated.

[0092] ② When the push cylinder 50 is activated, the piston rod extends and pushes the positioning plate 9 towards the motor body 1. The movement of the positioning plate 9 will cause the mounting plate 10, which is fixed to it, to move synchronously. When the mounting plate 10 moves, it will cause the L-shaped clamping plate 11 to move synchronously. When the L-shaped clamping plate 11 moves, it will push the bottom support plate 3 to move synchronously. At the same time, the positioning plate 9 and the push support plate 51 are fixedly installed. When the positioning plate 9 moves, the push support plate 51 also moves synchronously, so that the push support plate 51 always supports and lifts the bottom of the support base 2 until the arc-shaped end face of the reinforcing plate 4 is in contact with the side of the motor body 1. The push cylinder 50 pushes the positioning plate 9 to move, thereby realizing the clamping of the components. The overall movement of clamping assembly 8, while the side of the bottom support plate 3 contacts the vertical section of the L-shaped clamping plate 11, allows the clamping assembly 8 to move synchronously and push the bottom support plate 3, thus moving the support seat 2. The positioning plate 9 is fixed to the top push plate 51, so that when the positioning plate 9 moves, it pushes the top push plate 51 to move synchronously. The top push plate 51 is set at the center of the auxiliary support platform 7. The top push plate 51 and the auxiliary support platform 7 are supported together on the bottom surface of the bottom support plate 3. When the top push plate 51 moves synchronously with the support seat 2, the top push plate 51 always supports and lifts the support seat 2, making the entire movement adjustment process more reasonable and convenient, and the entire movement adjustment is automated.

[0093] ③ Both sides of the main support platform 18 are provided with auxiliary support plates 54. The top surface of the auxiliary support plate 54 is level with the bottom surface of the guide slot 52. When the push cylinder 50 pushes the push support plate 51 to move towards the motor body 1, the push support plate 51 gradually moves and supports itself on the auxiliary support plate 54. During the movement, the push support plate 51 will gradually move and support itself on the corresponding auxiliary support plate 54. The auxiliary support plate 54 provides auxiliary support and reinforcement for the push support plate 51, making the entire movement and adjustment process more stable and safe.

[0094] e. Welding equipment is used to weld and fix the contact surface between the reinforcing plate 4 and the motor body 1; the welding fixation between the reinforcing plate 4 and the motor body 1 effectively ensures the firmness of the connection between the two and extends the service life of the entire motor.

[0095] f. Remove the welded and assembled motor;

[0096] The steps for removing the motor are as follows:

[0097] ① Rotate the adjusting screw 39 upwards. The adjusting screw 39 will drive the top pressure plate 33 to move upwards until the top pressure plate 33 is completely separated from the motor body 1. Then loosen the limit nut 37 and rotate the adjusting plate 32 and the top pressure plate 33 completely out from above the motor body 1.

[0098] ② Loosen the clamping nut 14 and move the L-shaped clamping plate 11 upward until the horizontal section of the L-shaped clamping plate 11 moves away from the top surface of the bottom support plate 3 and the vertical section of the L-shaped clamping plate 11 moves away from the side of the bottom support plate 3.

[0099] ③ The push cylinder 50 is activated, and the piston rod retracts, causing the clamping assembly 8 to move away from the motor body 1 until the clamping assembly 8 is completely removed from above the bottom support plate 3; the push cylinder 50 causes the clamping assembly 8 to move back to its original position.

[0100] ④ Activate the horizontal adjustment component 17 and move the first limiting plate 15 and the second limiting plate 16 in opposite directions along the length of the auxiliary support platform 7 until the first limiting plate 15 and the second limiting plate 16 drive the positioning component 23 to be completely removed from the bottom support plate 3.

[0101] ⑤ Remove the motor body 1 from the main support platform 18; during the entire removal process, completely remove the top pressing component 22 from the motor body 1, and the pushing component 53 drives the clamping component 8 to move and reset, so that the clamping component 8 is completely removed from the bottom support plate 3. Then, start the horizontal adjustment component 17 to move the first limit plate 15 and the second limit plate 16 in opposite directions, release both ends of the bottom support plate 3, and then take out the assembled motor. The design is reasonable, the process is clean and easy to operate.

[0102] The above are merely specific embodiments of the present invention, but the technical features of the present invention are not limited thereto.

The adjusting plate will drive the top pressure plate to rotate synchronously until the top pressure plate is rotated and adjusted to be above the motor body. ②Turn the adjusting screw downwards. The adjusting screw will drive the top pressure plate to move downwards synchronously until the top pressure plate is matched and locked on the top of the motor body, and the top pressure plate and the top of the motor body are pressed together. Then tighten the limit nut.

4. The method for manufacturing a single-phase asynchronous motor according to claim 1, characterized in that: In step d of step (2), the placement of the reinforcing plate is as follows: ① Insert the reinforcing plate into the positioning slot of the positioning frame, and move and adjust the reinforcing plate along the positioning slot until the horizontal end of the reinforcing plate is placed on the corresponding bottom support plate. Then tighten the clamping screws to limit and fix the reinforcing plate and the positioning frame. ② Loosen the fastening nut, move the positioning rod along the limiting post and the embedded groove. The positioning rod will drive the reinforcing plate to move synchronously. At the same time, loosen the first clamping screw and adjust the position of the bottom support plate until the reinforcing plate is accurately positioned at the corresponding mark position on the bottom support plate. Then tighten the fastening nut and the first clamping screw.

A method for manufacturing a single-phase asynchronous motor according to claim 1, characterized in that: In step c of step (3), the adjustment steps of the positioning component are as follows: loosen the second tightening screw and the fastening nut, move the positioning rod along the limiting post and the embedded slot, the positioning rod drives the positioning frame to move synchronously until the reinforcing plate is completely disengaged from the positioning slot of the corresponding positioning frame, and then tighten the fastening nut.

6. A method for manufacturing a single-phase asynchronous motor according to claim 3, characterized in that: In step d of step (3), the movement of the support base is as follows: ① Each clamping assembly is connected to a corresponding pushing assembly. The pushing assembly includes a pushing cylinder and a pushing support plate. A guide slot is provided through the center of the auxiliary support platform along the width direction. The pushing support plate is slidably limited in the guide slot. The top surface of the pushing support plate is flush with the top surface of the auxiliary support platform. The positioning plate is fixedly installed on the pushing support plate. The piston rod end of the pushing cylinder is connected to the positioning plate. ② When the top-push cylinder is started, the piston rod extends and pushes the positioning plate towards the motor body. The movement of the positioning plate will cause the mounting plate, which is fixed to it, to move synchronously. When the mounting plate moves, it will cause the L-shaped clamping plate to move synchronously. When the L-shaped clamping plate moves, it will push the bottom support plate to move synchronously. At the same time, the positioning plate and the top-push support plate are fixedly installed. When the positioning plate moves, the top-push support plate also moves synchronously, so that the top-push support plate always supports and lifts the bottom of the support seat until the arc-shaped end face of the reinforcing plate is in contact with the side of the motor body. ③ Auxiliary support plates are provided on both sides of the main support platform. The top surface of the auxiliary support plate is level with the bottom surface of the guide slot. When the push cylinder pushes the push support plate towards the motor body, the push support plate gradually moves and supports itself on the auxiliary support plate.

7. A method for manufacturing a single-phase asynchronous motor according to claim 6, characterized in that: In step f of step (3), the removal of the motor is as follows: ① Turn the adjusting screw upwards. The adjusting screw will cause the top plate to move up until the top plate is completely separated from the motor body. Then loosen the limit nut and turn the adjusting plate and the top plate completely out from above the motor body. ② Loosen the clamping nut and move the L-shaped clamping plate upwards until the horizontal section of the L-shaped clamping plate moves away from the top surface of the bottom support plate and the vertical section of the L-shaped clamping plate moves away from the side of the bottom support plate. ③ The top-pushing cylinder is started, and the piston rod retracts, driving the clamping assembly to move away from the motor body until the clamping assembly is completely removed from above the bottom support plate; ④ Activate the horizontal adjustment component and move the first and second limit plates in opposite directions along the length of the auxiliary support platform until the first and second limit plates drive the positioning component to be completely removed from the bottom support plate. ⑤ Remove the motor body from the main support platform.
