Description

Technical Field

[0001] The invention belongs to the technical field of motors, and in particular relates to a high-speed and high-power single-phase asynchronous motor and a manufacturing method thereof. Background Art

[0002] A single-phase asynchronous motor refers to a low-power single-phase asynchronous motor powered by a single-phase AC power supply (AC220V). Its power design is relatively small, generally not greater than 2kW. When the existing single-phase asynchronous motor is in use, the wires connected to the surface of the motor generally hang down naturally, resulting in direct friction between the wires and the installation surface, and the surface of the wires is worn and contaminated, causing safety hazards. Moreover, since there are more than one wires connected to the surface of the motor, it is easy for the wires to get entangled, which makes it inconvenient for subsequent maintenance and replacement of the wires. When installing existing motors, the support device is generally welded under the bottom of the motor. However, since the welding part is located at the bottom and the motor shell is mostly a cylindrical structure, it is not convenient for actual welding operations, which affects the actual welding quality. Summary of the invention

[0003] The purpose of the present invention is to provide a technical solution for a high-speed and high-power single-phase asynchronous motor and a manufacturing method thereof in view of the deficiencies in the prior art. The stability of the placement of the motor body is ensured by a support base, which facilitates the installation and fixation between the motor and the placement surface. The wires on the surface of the motor body can be guided and combed by a wire management plate assembly, which is convenient for the centralized management of the wires and prevents wear and pollution on the surface of the wires. At the same time, the wire management plate assembly can cooperate with the installation of a top guard plate to shield and protect the top of the motor body through the top guard plate, thereby delaying the service life of the motor body. In the present invention, an auxiliary device is used to realize the welding operation between the various components of the support base and between the support base and the motor body. During the gradual welding process, the welding surfaces between the various components of the support base and between the support base and the motor body are all adjusted to the top, thereby facilitating the actual welding operation, facilitating the adjustment of the welding position of the components, improving the welding accuracy, and making the operation safer and more convenient.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The contact area between the support base and the placement surface can be increased through the design of the fixing plate to ensure the stable placement of the support base, and the fixing plate can also facilitate the installation and fixation between the support base and the placement surface.

[0007] Furthermore, a fixing hole is provided on the fixing plate, and a reinforcing support plate is provided between the top surface of the fixing plate and the outer side wall of the motor body. The installation and fixation between the support base and the placement surface are realized through the design of the fixing hole.

The design of the reinforced support plate makes the structure of the support base more solid and reliable, improves the connection firmness between the fixing plate and the motor body, ensures the supporting and stabilizing effect of the support base on the motor body, and has better structural safety performance.

[0008] Furthermore, the wire management frame is provided with at least five wire management slots with reasonable design. The design of multiple wire management slots can realize the docking and guidance of multiple wires, and appropriate wire management slots can be selected according to the actual positions of the wires for combing and guiding, which is convenient for the subsequent maintenance and management of the wires on the surface of the motor, and effectively prevents the wires from directly falling on the placement surface and directly rubbing against the placement surface, etc., thereby protecting the wires and improving the operational safety performance.

[0009] Furthermore, through slots are provided on the top opposite surfaces of the two wire-managing frame plates, and the through slots match the top guard plate. The top guard plate is inserted between the two wire-managing frame plates through the through slots, and the top guard plate is tightened and limited with the wire-managing frame plates by fixing screws. Through the ingenious design of the through slots, the insertion and limiting between the top guard plate and the two wire-managing frame plates is achieved, and then the fixing screws are further tightened and limited, which effectively ensures the firm installation performance between the top guard plate and the two wire-managing frame plates, thereby ensuring the shielding and protective effect of the top guard plate on the motor body, and the overall disassembly is simple and convenient, and easy to operate.

[0010] Furthermore, a positioning rod is provided at the bottom end of the wire management frame, and an adjustment slot is provided on the top surface of the adjustment frame. The positioning rod matches the adjustment slot, and the positioning rod is movably inserted in the adjustment slot. Through the design of the positioning rod and the adjustment slot, the initial insertion limit between the wire management frame and the adjustment block is achieved, and the positioning rod can move up and down along the adjustment slot, so that the upper and lower heights of the wire management frame can be adjusted according to actual needs.

[0011] Furthermore, a limit slot is provided on the side of the adjusting frame, the limit slot is connected with the adjusting slot, a limit block is provided at the bottom of the positioning rod, the limit block matches the limit slot, the limit block is movably connected in the limit slot, a threaded rod is provided at the end of the limit block, the threaded rod is fixed to the adjusting frame by a limit nut, and further movable connection between the positioning rod and the adjusting frame is achieved through the limit slot and the limit block, and then with the help of the threaded rod and the limit nut, when the height of the wire management frame is adjusted and the positioning rod is moved into place, the limit nut is tightened to indirectly lock the positioning rod to limit the position, thereby ensuring the structural firmness of the entire wire management board assembly, and when the position of the positioning rod needs to be adjusted, the limit nut can be loosened. The design is ingenious and reasonable, and the overall installation and disassembly is convenient and simple, and easy to operate.

[0012] Furthermore, opening grooves are provided on opposite surfaces of the two fixed plates, and an extension plate of an integrally formed structure is provided at the bottom end of the adjusting frame. The extension plate matches the opening groove, and the extension plate is clipped into the opening groove, and the extension plate is fixed to the fixing plate with screws. The opening groove and the extension plate can achieve precise clip-on positioning between the adjusting frame and the fixing plate, which is convenient for installation. The extension plate and the fixing plate are then installed and fixed by screws. The connection method is flexible and simple, and at the same time, the firm installation performance between the adjusting frame and the fixing plate can be ensured.

[0013] The manufacturing method of the high-speed and high-power single-phase asynchronous motor as described above is characterized by comprising the following steps:

[0014] 1) Preparation of support base: Prepare support blocks, two fixing plates and several reinforcing support plates according to the design dimensions;

[0015] 2) Welding of the support base and the motor body:

[0016] (1) Place the motor body on the arc-shaped supporting plate of the auxiliary device, move the motor body in the direction of the limiting ring, so that the rear end of the motor body is stuck in the limiting ring, then insert the side support plate into the adjusting rod, and move the side support plate along the adjusting rod toward the motor body until the side support plate is pressed against the front end surface of the motor body, tighten the first clamping screw, and the motor shaft at the front end of the motor body extends out through the through hole on the side support plate; first, support the bottom of the motor body with the arc-shaped supporting plate, and set the part of the motor body welded with the support block facing upward, then limit the rear end of the motor body with the limiting ring, and then combine with the cooperation of the side support plate to clamp and limit from the front and rear ends of the motor body at the same time, and the arc-shaped supporting plate always supports the motor body, thereby effectively ensuring the stability of the placement and firmness of the motor body on the auxiliary device, and completely exposing the top of the motor body, so as to facilitate the subsequent welding operation between the support base and the motor body;

[0017] (2) Then place the support block on the top of the motor body with the arc surface facing the outer wall of the motor body. Adjust the front and rear position of the support block on the motor body according to the design requirements, loosen the locking nut, rotate the top pressure piece toward the support block so that the top pressure piece is rotated to a horizontal position, tighten the locking nut, rotate the adjusting screw, and the adjusting screw drives the top pressure plate to move downward until the top pressure plate is pressed against the top surface of the support block. The support block is welded and fixed to the motor body by a welding device. The support block is attached to the top outer wall of the motor body through the arc surface, and the front and rear position of the support block is adjusted along the surface of the motor body so that the support block moves to the designed welding position. , rotate the top pressure piece to a horizontal position, and rotate the adjusting screw, while the end of the adjusting screw is fixedly connected to the top pressure plate through the bearing, so that the rotation of the adjusting screw can synchronously drive the top pressure plate to move downward, and the support block is pressed and limited at the top of the motor body by the top pressure plate to ensure a close fit between the support block and the motor body, and then cooperate with the welding device to perform welding operations, effectively improving the welding quality, and because the top pressure plate presses and limits the support block, and the motor body is clamped and supported, it is ensured that the support block and the motor body will not move during the welding process, thereby improving the welding accuracy, and no manual auxiliary pressing is required during the entire welding process, and the operation is safer;

[0018] (3) Loosen the locking nut and rotate the top pressure piece until the top pressure piece is completely turned out from above the support block, tighten the locking nut, and insert the two fixing plates into the two limit frames respectively, ensuring that the insertion rods at the bottom of the limit frames are inserted into the opening grooves on the fixing plates accordingly; turning the top pressure piece out from above the support block can ensure that the support block is completely exposed, thereby facilitating the subsequent welding operation between the fixing plate and the support block, and realizing the clamping and limiting of the fixing plate through the limit frame, and at the same time, realizing further precise limiting between the fixing plate and the limit frame through the ingenious insertion of the insertion rod and the opening groove, and when the insertion rod is pressed against the end face of the opening groove, the fixing plate can only be moved out horizontally in the limit frame, and cannot be displaced in other directions, effectively ensuring the clamping stability between the fixing plate and the limit frame, and ensuring the clamping and supporting effect of the limit frame on the fixing plate;

[0019] (4) The lifting cylinder is started, and the lifting cylinder drives the two adjusting frames to move synchronously through the connecting plate, and the adjusting frame drives the movement of the limit frame, thereby realizing the adjustment of the upper and lower heights of the fixed plate until the top surface of the fixed plate is flush with the horizontal surface of the support block, loosen the second clamping screw, move the limit frame toward the support block, and the dovetail block of the limit frame slides horizontally along the dovetail slide groove of the adjusting frame until the fixed plate contacts the side of the support block, tighten the second clamping screw, and then loosen the third clamping screw, move the adjusting frame to adjust the front and rear position of the limit frame, and the limit frame drives the fixed plate to move forward and backward along the side of the support block until the horizontal center of the fixed plate moves to correspond to the horizontal center of the horizontal plane of the support block, tighten the third clamping screw, and weld the two fixed plates to the side of the support block respectively through the welding device; the upper and lower heights of the two fixed plates are finally adjusted by the lifting cylinder, so that the top surface of the fixed plate is flush with the horizontal top surface of the support block. The second clamping screw can be loosened to adjust the left and right positions of the fixing plates, so that the welding sides of the two fixing plates are respectively pressed against the two sides of the supporting block, ensuring the close fit between the two corresponding welding sides, thereby improving the subsequent welding quality and ensuring the welding firmness between the fixing plates and the supporting blocks. Moreover, since the fixing plates can only be moved out laterally after being inserted into the limit frame, when the fixing plates are pressed against the sides of the supporting blocks, the sides of the supporting blocks limit the lateral movement of the fixing plates, ensuring that the fixing plates will not shift during the welding process, improving the welding quality. The third clamping screw can be loosened to adjust the front and rear positions of the fixing plates, so that the horizontal center line of the fixing plates corresponds to the horizontal center line of the supporting blocks, improving the overall structural balance of the fixing plates, and making the combined structure of the supporting base and the motor body more stable and reliable after welding.

[0020] (5) Loosen the third clamping screw and move the limit frame away from the fixed plate until the limit frame is completely separated from the fixed plate and there is a gap between them, tighten the third clamping screw, loosen the first clamping screw, rotate the motor body 90 degrees axially to one side so that the two fixed plates are vertically distributed up and down, press the side abutment plate and tighten the first clamping screw, and use the welding device to weld and fix the reinforcing support plate between the upper fixed plate and the motor body, loosen the first set screw, rotate the motor body 180 degrees in the opposite axial direction, rotate the fixed plate at the bottom to the top, press the side abutment plate and tighten the second clamping screw, and then use the welding device to weld and fix the reinforcing support plate between the fixed plate and the motor body; The frame is moved away from the fixed plate, and a certain distance is left between the fixed plate, so as to leave operating space for the subsequent rotation of the motor body. The motor body is first rotated 90° to one side, and one fixed plate can be rotated to the upper vertical setting, so as to facilitate the welding operation of the reinforcing support plate between the fixed plate and the motor body. Then, the other fixed plate can be rotated 180° in the opposite direction to the upper vertical setting, so as to facilitate the welding operation of the reinforcing support plate between the fixed plate and the motor body. The design is reasonable. Through two rotations, the welding operation of the reinforcing support plates between the two fixed plates and the motor body is located at the upper part, which is convenient for the operator to observe and supervise the welding work, and is also convenient for the actual welding operation.

[0021] (6) Loosen the first clamping screw, remove the side support plate from the adjustment rod, and then remove the combination of the motor body and the support base from the auxiliary device;

[0022] 3) Preparation of cable management board assembly:

[0023] (1) According to the design dimensions, a combination of a limit block and a threaded rod, a wire management frame plate, a positioning rod and an adjustment frame of an integrated structure are prepared;

[0024] (2) Weld and fix the positioning rod to the designed position at the bottom end of the wire management frame;

[0025] (3) Then, insert the positioning rod into the adjustment slot of the adjustment frame, and then use glue to stick the combination of the limit block and the threaded rod to the designed position on the side of the positioning rod, and then screw the limit nut into the end of the threaded rod; it is easy to assemble, firstly, the positioning rod and the adjustment frame are movablely connected through the adjustment slot, and then the limit block and the threaded rod of the one-piece structure are welded to the reserved position on the side of the positioning rod, and the positioning rod is restricted from sliding out of the adjustment slot by the limit block, and at the same time, the threaded rod can cooperate with the limit nut to realize the limit fixation of the positioning rod and the adjustment frame;

[0026] 4) Connection of the cable management plate assembly and the support base: match the extension plate at the bottom of the adjustment frame with the opening groove on the fixed plate, so that the extension plate is completely inserted into the opening groove, and then the top of the extension plate is further installed and fixed between the fixed plate by screws; the extension plate and the opening groove are used to achieve precise clamping and positioning between the adjustment frame and the fixed plate, and then the screws are used to ensure the installation firmness between the adjustment frame and the fixed plate, thereby achieving the installation and fixation between the cable management plate assembly and the support base, and the overall installation and disassembly are convenient and simple;

[0027] 5) Installation of the top guard plate: First, cut a top guard plate of appropriate length according to the actual length of the motor body shell, ensure that the length of the top guard plate is greater than the length of the motor body shell and the length of the top guard plate is greater than the length of the wire management frame, align the top guard plate with the through slots on the wire management frame from the side, insert both sides of the top guard plate into the through slots, and then adjust the position of the top guard plate to ensure that both ends of the top guard plate extend out of the through slots, and then tighten the setting screws on the top surface of the wire management frame to limit the top guard plate. By limiting the length of the top guard plate, the shielding and protection of the top guard plate on the top of the motor body can be guaranteed, and the top guard plate and the two wire management frames can be connected through the through slots, and then the setting screws are used to limit the installation to ensure the firmness of the installation between the top guard plate and the wire management frame.

[0028] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0029] The present invention ensures the placement stability of the motor body through the support base, which is convenient for the installation and fixation between the motor and the placement surface, and the support base and the motor body are fixed by welding, so that the motor body and the support base are integrated, effectively ensuring the overall structural stability of the motor, and facilitating the smooth placement and positioning installation of the motor. The wires on the surface of the motor body can be guided and combed through the wire management plate assembly, which is convenient for the centralized management of the wires and prevents the wear and pollution of the wire surface. At the same time, the wire management plate assembly can cooperate with the installation of the top guard plate, and the top of the motor body is shielded and protected by the top guard plate to delay the service life of the motor body. At the same time, the height of the wire management frame is adjustable, and can be appropriately adjusted according to the docking position of the wires and the actual height of the motor body, which is more conducive to the combing of the wires, ensuring that the top guard plate and the top of the motor body have a certain distance, thereby ensuring the ventilation and heat dissipation of the motor body surface, and facilitating the layout and installation of other components on the surface of the motor body.

[0030] In the present invention, an auxiliary device is used to realize the welding operation between the various components of the support base and between the support base and the motor body. In the process of gradually carrying out welding, the welding surfaces between the various components of the support base and between the support base and the motor body are all adjusted to the upper side, so as to facilitate the actual welding operation and the adjustment of the welding position of the components, which is beneficial to the operator to monitor the welding position, welding progress and welding quality, improve the welding accuracy and welding quality, and the operation is also safer and more convenient. First, the welding between the support block and the motor body is carried out, and the top pressure piece presses the support block, and the motor body realizes support limitation through the side abutment plate and the arc-shaped support plate, so as to ensure that the support block and the motor body will not be offset during the welding operation. Then, the welding between the fixed plate and the support block is carried out, and the fixed plate is clamped and limited through the limit frame, and then the upper and lower front and rear left and right positions of the fixed plate are adjusted in conjunction with other components of the auxiliary device, so as to ensure the welding accuracy between the fixed plate and the support block. Finally, the welding of the reinforcing support plate is carried out, and the reinforcing support plates on the two fixed plates are welded in turn, so as to ensure that the fixed plate for the actual required welding operation is rotated to the upper side, so as to facilitate the actual welding operation.
