Description

Technical Field

[0001] The invention relates to the technical field of motor stator processing, in particular to a motor piece bevel slot stator processing device. Background Art

[0002] The slots in the stator core of the permanent magnet synchronous motor interact with the permanent magnets of the rotor to form tooth harmonic electromagnetic torque, which increases noise, vibration, and eddy current losses. The skewed slots on the stator core of the motor can improve the magnetic circuit and weaken high-order electromagnetic harmonics, thereby achieving a smooth waveform of the generator, reducing its noise and vibration, reducing losses and improving efficiency. It is one of the most widely used and effective methods to suppress tooth torque pulsation and must be processed using relevant processing equipment.

[0003] The patent publication number is CN114552906B, which is a method and equipment for processing a splice bevel slot stator for a motor. Its structure mainly includes a mold base, a vertical pole, a processing assembly, a welding rod, a welding gun, a driving mechanism and a machine. When working, the working parameters of the welding rod for welding the splice bevel slot stator are set, and the welding rod is driven to move along the diameter direction of the splice bevel slot stator by controlling the transverse movement mechanism, and the welding rod is driven to rotate to a certain angle by controlling the angle adjustment mechanism, and then the welding rod is controlled by controlling the oblique movement mechanism to perform welding along the direction of the bevel slot. After the welding of one group of bevel slots is completed, the welding rod is moved in the circumferential direction by controlling the driving mechanism to achieve welding of the next group of bevel slots.

[0004] However, when the above equipment is processing, the motor stators are loaded and unloaded and processed one by one, and it is necessary to wait until the previous stator is processed and unloaded before loading and processing can be carried out again. When processing batches of workpieces, the processing time will increase and the processing efficiency will decrease.

During the approaching process, the positioning assembly is connected to the positioning adjustment structure, so that the position of the positioning assembly is adjusted by the positioning adjustment structure, so that it moves to the top of the stator and moves downward to limit the top of the motor stator, so that before the stator moves to the welding assembly, the stator is limited in the circumferential direction and the vertical direction;

[0055] With the intermittent rotation of the rotating assembly, the positioned stator moves to the first welding assembly, and is driven by one of the circumferential adjustment assemblies to slowly rotate the motor stator, and while rotating, the welding assembly moves down to form an oblique welding structure on the stator assembly sheet, and each time the rotating assembly rotates once, the stator is transferred to the next welding assembly, and the welding process of the oblique slot stator is completed through the cooperation of multiple welding assemblies;

[0057] The present application realizes multi-station processing by setting up a rotating component and multiple positioning mechanisms, and completes loading, adjusting positioning, multiple welding, and unloading in sequence when the stator moves intermittently in the circumferential direction, thereby realizing continuous processing and improving work efficiency. In addition, loading, adjusting positioning, multiple welding, and unloading can be performed simultaneously at different positions of the rotating component, further improving processing efficiency and enabling batch processing.

[0059] Among them, Figure 2As shown, the circumferential limit assembly includes an adjustment seat 400 located in the adjustment groove 303, guide grooves 403 are provided on both side walls of the adjustment seat 400, and both side edges of the adjustment groove 303 are slidably connected to the corresponding guide grooves 403, and a fixing frame 402 is provided on the top surface of the adjustment seat 400. Figure 4 As shown, a vertical fixed cylinder 404 is provided between the fixed frame 402 and the adjustment seat 400, and the positioning assembly is located in the fixed cylinder 404, the two ends of the fixed cylinder 404 extend out of the adjustment seat 400 and the fixed frame 402 respectively, and the bottom end of the fixed cylinder 404 is correspondingly connected to the circumferential adjustment assembly, and the outer side of the fixed cylinder 404 is rotatably connected with an adjusting wheel 401, and a transmission gear 405 is also fixed to the bottom of one of the adjusting wheels 401 located on the inner side of the fixed plate 301, and a driving gear 406 is meshed with a side of the transmission gear 405 close to the fixed frame 402, and a motor is connected to the bottom of the driving gear 406.

[0060] After the placement and loading of multiple stator components are completed, the multiple fixed cylinders 404 are driven to move by the circumferential adjustment assembly, and the adjustment seat 400 is limited and guided by the adjustment groove 303 and moves along the length direction of the adjustment groove 303, that is, the multiple adjustment seats 400 and the adjustment wheel 401 move inward along the radius direction of the fixed plate 301 at the same time, so that the circumferential positions of the multiple stator components are adjusted by the three circumferential adjustment wheels 401, so that the overall structural position of the stator is more neat and accurate, which is convenient for subsequent positioning and welding processing. A friction pad can be set on the wheel surface of the adjustment wheel 401 to increase the friction between the adjustment wheel 401 and the stator components and improve the driving stability;

[0061] When welding is performed, one of the regulating wheels 401 drives the stator component piece to rotate slowly as a whole through the drive of the motor and the transmission of the drive gear 406 and the transmission gear 405. During the rotation, welding is performed through the moving welding assembly, thereby realizing oblique welding processing.

[0062] Among them, Figure 8 As shown, the circumferential adjustment component includes an adjusting toothed disc 600 located at the upper part of the inner cavity of the fixed groove 302, the center of the adjusting toothed disc 600 is rotatably connected to the bottom end of the rotating column 308, one side of the adjusting toothed disc 600 is meshed with a pushing rack 602, a notch is provided on the side wall of the fixed groove 302 corresponding to the position of the pushing rack 602, and a pushing block 603 is fixed to the outer side surface of the pushing rack 602, one side of the pushing block 603 is connected to a telescopic cylinder 604, and one end of the telescopic cylinder 604 is fixedly connected to the outer side wall of the fixed groove 302 through a bracket 605, three pushing grooves 601 are evenly arranged along the circumferential direction of the adjusting toothed disc 600, the length direction of the pushing groove 601 is inclined relative to the radius direction of the adjusting toothed disc 600, the fixed cylinder 404 is located in the corresponding pushing groove 601, and the bottom end passes through the pushing groove 601.

[0063] When adjusting the positions of the three fixed cylinders 404 and the adjustment seat 400, the push rack 602 is moved by the telescopic cylinder 604, thereby driving the adjustment toothed disc 600 to rotate. During the rotation, the fixed cylinder 404 and the adjustment seat 400 are moved along the length direction of the adjustment groove 303 through the inclined pushing groove 601, thereby realizing the position adjustment of multiple adjustment wheels 401 and adjusting the position of the corresponding positioning assembly to be located above the stator.

[0064] Among them, Figure 4 As shown, the positioning assembly includes a vertical positioning pressure shaft 500 slidably connected to the fixed cylinder 404, and both ends of the positioning pressure shaft 500 extend out of the fixed cylinder 404, a pressure plate 501 is fixed to the top of the positioning pressure shaft 500, and a pressure block 502 is fixed to the bottom of the pressure plate 501, as shown in FIG. Figure 5 As shown, a plurality of balls are evenly arranged at the bottom of the pressing block 502;

[0065] like Figure 6 As shown, a transverse steering short column 503 is fixed to the upper part of the positioning pressure shaft 500, and a steering groove 407 is provided on the inner side wall of the fixed cylinder 404. The end of the steering short column 503 is located in the steering groove 407, and as shown in FIG. Figure 7 As shown, the upper side section of the steering groove 407 is inclined, and the lower side section is vertically arranged;

[0066] like Fig. 9 As shown, the bottom end of the positioning pressure shaft 500 is located in the fixed groove 302 and is rotatably connected to a lifting slider 504. An end plate 408 is fixed to the bottom end of the fixed cylinder 404. The end plate 408 and the lifting slider 504 are connected by a spring. Limiting grooves 505 are provided on both sides of the lifting slider 504. The three lifting sliders 504 in the fixed groove 302 are connected to the same positioning transmission structure through the limiting grooves 505, and the positioning transmission structure is correspondingly connected to the positioning adjustment structure.

[0067] When adjusting the position of the adjustment wheel 401 and other structures, the positioning pressure shaft 500 moves accordingly, and when it approaches the welding assembly after completing the circumferential position adjustment, the positioning transmission structure is connected correspondingly to the positioning adjustment structure, and drives the lifting slider 504 and the positioning pressure shaft 500 to move downward. In the process of the positioning pressure shaft 500 moving downward, the steering short column 503 moves along the inclined section of the steering groove 407, thereby driving the lifting shaft 508 to rotate relative to the fixed cylinder 404, and when the steering short column 503 moves to the vertical section of the steering groove 407, the pressure plate 501 and the pressure block 502 rotate from the outer position of the adjustment wheel 401 to the inner position of the adjustment wheel 401, so as to be located above the stator, and when the lifting shaft 508 continues to move downward, the pressure block 502 is pressed on the top of the stator, which plays a role in limiting the height position, and contacts with the stator through the ball bearing to avoid affecting the subsequent rotation welding operation of the stator.

[0068] Embodiment 2: The structure of this embodiment is basically the same as that of embodiment 1, except that Fig.10 As shown, the positioning transmission structure includes a lifting shaft 508 that is vertically slidably connected to the center of the bottom surface of the fixed groove 302, a lifting plate 507 is fixed to the top of the lifting shaft 508, a spring is connected between the bottom surface of the lifting plate 507 and the bottom surface of the fixed groove 302, and two parallel limiting slide bars 506 are fixed on the outer side of the lifting plate 507 corresponding to the position of each lifting slider 504, the limiting slide bars 506 are slidably connected to the corresponding limiting slide grooves 505, the bottom end of the lifting shaft 508 extends out of the fixed groove 302, and is fixed with a horizontal positioning pull shaft 509, and the end of the positioning pull shaft 509 is correspondingly connected to the positioning adjustment structure.

[0069] When the adjustment seat 400 and the adjustment wheel 401 are adjusted in position, the lifting shaft 508 and the limit slider move along the limit slider 506. When the position of the pressure plate 501 needs to be adjusted, the positioning pull shaft 509, the lifting shaft 508 and the lifting plate 507 drive the limit slider 506 to move downward through the positioning structure, and then drive the limit slider and the positioning pressure shaft 500 and other structures to move downward, so as to complete the steering and positioning operations of the pressure plate 501 and the pressure block 502 during the downward movement.

[0070] like Figure 1 As shown, the positioning adjustment structure includes an arc-shaped positioning plate 103 vertically located above the base 100, and the position of the positioning plate 103 corresponds to the position of the welding assembly. The bottom of the positioning plate 103 is connected to the base 100 through a plurality of lifting cylinders 102 evenly arranged, and a positioning groove 104 is provided on the inner side of the positioning plate 103. Fig.11 As shown, the positioning groove 104 includes a horizontal entry section and a positioning section. The height of the entry section is higher than the positioning section, the groove width of the entry section is greater than the groove width of the positioning section, and the entry section and the positioning section are connected by an inclined guide section.

[0071] After the motor stator completes the circumferential position adjustment, it approaches the positioning pull plate 103 under the action of the rotating component. The height position of the positioning pull plate 103 is adjusted by the lifting cylinder 102 to adjust the downward movement distance of the positioning pull shaft 509, the pressure plate 501 and other structures. Before the positioning pull shaft 509 approaches the welding component, the end of the positioning pull shaft 509 first enters the entry section of the positioning groove 104, and under the continued rotation of the rotating component, it enters the positioning section along the guide section, so that the positioning pull shaft 509 drives the lifting shaft 508 and other structures to move downward, thereby realizing the downward movement and position adjustment of the pressure plate 501, and completing the positioning operation before the stator moves to the welding component. After completing multiple welding processes, when approaching the unloading position, the positioning pull shaft 509 is disengaged from the positioning groove 104, so that the lifting shaft 508 and the lifting plate 507 and other structures return to their original positions under the action of the spring, canceling the positioning of the motor stator for unloading operations.

[0072] Embodiment 3: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 1 As shown, the rotating assembly includes a fixed column 101 vertically fixed to the top of the base 100, the top of the fixed column 101 is rotatably connected to the rotating table 300, the fixed slot 301 is fixed on the rotating table 300, a driving cavity and a motor are provided in the fixed column 101, and the bottom center of the rotating table 300 is connected to the driving shaft of the motor, the rotating table 300 is driven by the motor to rotate a certain angle, then pause, and repeat, thereby realizing intermittent rotation of the rotating table 300, switching multiple positioning mechanisms and the corresponding positions of the motor stators, so that the motor stators are loaded, adjusted and positioned, welded multiple times and unloaded in turn.

[0073] Embodiment 4: The structure of this embodiment is basically the same as that of embodiment 1, except that Figure 1 As shown, the welding assembly includes an arc-shaped support plate 201 fixed to one side of the base 100, a horizontal arc-shaped top plate 200 is fixed to the top of the arc-shaped support plate 201, a horizontal arc-shaped moving plate 205 is connected to the bottom of the top plate 200 through a plurality of evenly arranged moving cylinders 204, and a plurality of mounting seats 206 are provided at the bottom of the moving plate 205 corresponding to the positions of the plurality of positioning mechanisms below, as shown in FIG. Figure 3 As shown, a welding gun 207 is mounted on each mounting seat 206, and the mounting seat 206 can be connected to the mounting plate through a structure such as a cylinder, so that the horizontal position of the welding gun 207 can be adjusted to ensure the contact between the welding gun 207 and the motor electronics and the welding process.

[0074] When the motor stator moves to the position of the first welding gun 207, the moving cylinder 204 drives the moving plate 205 and the welding gun 207 to move downward so that welding can be performed while the motor stator rotates, thereby realizing oblique welding processing. Through the intermittent rotation of the rotating assembly, the motor stator passes through multiple welding guns 207 in sequence to complete multiple welding processes.
