Description

Technical Field

[0002] The efficiency and performance of a motor depend largely on the design and manufacture of its internal components, especially the stator and rotor laminations. The stator and rotor laminations are key components made of silicon steel sheets. They not only provide structural support, but are also responsible for guiding the electromagnetic flux, thus affecting the overall efficiency of the motor. The stator and rotor laminations are an important component in motor manufacturing. They are usually made of silicon steel sheets to support the windings and guide the electromagnetic flux. In a motor, the stator is the fixed part and the rotor is the rotating part. The manufacture of the laminations involves precise stamping technology to ensure dimensional accuracy and proper insulation, thereby reducing the heat loss of eddy currents. These laminations are usually in a stacked form to improve motor efficiency and performance.

The present invention can improve the production efficiency of the stator and rotor punching sheets.

[0004] When the existing electronic stator and rotor punching sheets are continuously stamped on multiple groups of stator slots and other slot bodies, a reference point is needed to ensure the accuracy of the stamping position. However, the component that can provide the reference will interfere with the placement of the unprocessed blank disc and the removal process of the parts after stamping, thereby affecting its processing efficiency. At the same time, during the continuous stamping operation, the blank disc may be relatively displaced from the reference surface on which it is placed, which may affect the processing accuracy. Therefore, a stator and rotor punching sheet processing technology is proposed. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 12 The present invention provides a technical solution: a stator and rotor punching processing technology, comprising the following steps: S1. Initial positioning of parts: In the initial state, the top octagonal column 7 is extended to expose the positioning plate 6, and the stator slot in the blank plate 4 is sleeved on the top octagonal column 7, and the top octagonal column 7 provides initial positioning for the blank plate 4; S2, blank fixation: the blank plate 4 is made coaxial with the top-extending octagonal column 7 through the co-location component, and the blank plate 4 is pressed tightly on the positioning plate 6; S3, displacement stamping: the upper die seat 2 moves downward and completes the stamping process of a single group of stator slots on the blank plate 4. After completing a single stamping, the upper die seat 2 moves upward and drives the positioning plate 6 to rotate in the horizontal direction at a set angle through the positioning component to change the relative position between the blank plate 4 and the upper die seat 2 and the lower die seat 3; S4, reset and unloading: the same position component releases the pressing restriction on the blank plate 4, and the relocation component drives the top extension octagonal column 7 to move downward, and removes the stamped parts from the positioning plate 6; S5, datum reset: drive the top-extending octagonal column 7 to rise and expose the positioning plate 6 through the relocation component, so that the top-extending octagonal column 7 is restored to the initial state, providing an initial positioning datum for the next group of unprocessed blank plates 4.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, when the stator and rotor punching processing in the motor is carried out, the blank plate 4 that has been pre-processed is placed on the positioning plate 6, even if the blank plate 4 with a rotor hole is placed on the positioning plate 6, wherein the diameter of the top-extending octagonal column 7 is smaller than the diameter of the rotor hole, so that the rotor hole can be roughly mounted on the top-extending octagonal column 7, thereby providing a placement reference point for the blank plate 4 by exposing the top-extending octagonal column 7 to a certain height of the positioning plate 6, and because the top-extending octagonal column 7 is relatively small relative to the diameter of the rotor hole, there is a gap between the two, so that the staff does not need to complete the precise loading process of the blank plate.

[0022] At the same time, the blank disc 4 is driven to move in the horizontal direction by the isotropic component until the blank disc 4 and the top extended octagonal column 7 are coaxial. The processing position of the blank disc 4 is determined, that is, the spacing length between the stamping position and the rotor hole is determined. At the same time, after the processing position of the blank disc 4 is determined, the isotropic component can press the blank disc 4 tightly against the positioning disc 6 to avoid relative movement between the positioning disc 6 and the blank disc 4 when the positioning disc 6 is rotated to change the stamping position, thereby ensuring that the blank disc 4 can rotate synchronously with the positioning disc 6 to ensure the accuracy of the stamping position, thereby ensuring the processing accuracy.

[0023] During the processing of stator and rotor punching, the blank plate 4 is located between the upper die base 2 and the lower die base 3, and the upper die base 2 is driven to move toward the lower die base 3 by the stamping slider 101 that moves in the vertical direction on the stamping device 1. When the upper die base 2 moves downward, the positioning component limits the position of the positioning plate 6 to avoid the phenomenon of stamping position deviation. At the same time, when the upper die base 2 moves upward, the positioning component can drive the positioning plate 6 and the co-positioning component to rotate synchronously, thereby driving its blank plate 4 to rotate a set angle in the horizontal direction, thereby changing the relative position between the blank plate 4 and the upper die base 2 and the lower die base 3, so that during continuous stamping operations, the position of the blank 4 can be automatically changed, thereby increasing the stamping speed.

[0024] After completing the stamping operation of a single motor stator punching sheet, the isotropic component releases the tight pressure restriction on the blank plate 4, and the top extended octagonal column 7 moves downward until the horizontal height of its top end is lower than the horizontal height of the positioning plate 6, so as to facilitate the staff to remove the formed parts from the positioning plate 6 to avoid the existence of the top extended octagonal column 7 interfering with the unloading process. At the same time, after completing the unloading process, the top extended octagonal column 7 returns to its initial height to ensure that it can provide an initial positioning reference point for the next group of blank plates 4 that need to be processed.

[0025] In one of the more preferred embodiments, a process for processing stator and rotor punching sheets includes a punching device 1 for punching and forming stator punching sheet components in a motor, the punching device 1 is provided with a base for placing a blank plate 4 with a pre-processed rotor hole, the punching device 1 is also provided with an upper die seat 2 and a lower die seat 3 for punching and forming stator slots on the blank plate 4, the punching device 1 includes a punching slide block 101 for driving the upper die seat 2 to move vertically toward the lower die seat 3, and the base is provided with a displacement structure for adjusting the relative position of the blank plate 4 and the lower die seat 3; The displacement structure comprises an annular seat 5 fixedly connected to the base, a positioning plate 6 directly in contact with the blank plate 4 is arranged on the annular seat 5, a circular groove is opened on the positioning plate 6 corresponding to the position of the rotor hole, and a positioning component for driving the positioning plate 6 to rotate horizontally is arranged on the base; The base is provided with an octagonal top column 7 for initial positioning of the blank plate 4 at the position corresponding to the circular groove, and a co-location component for positioning the blank plate 4 processing position is provided on the octagonal top column 7, and a relocation component for driving the octagonal top column 7 to rise and fall is provided on the base.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, when the motor stator and rotor punching sheets are stamped, the unprocessed blank disk 4 is placed on the positioning disk 6, and the processing position of the blank disk 4 is positioned by the isotropic component, and during the continuous stamping process, the positioning disk 6 and the isotropic component are driven to rotate synchronously by the positioning adjustment component, thereby ensuring that during the rotation of the positioning disk 6, the blank disk 4 thereon will not be displaced relative to it, thereby ensuring the accuracy of the stamping position during the continuous stamping process, thereby achieving the purpose of ensuring the processing accuracy.

[0027] At the same time, the top-extending octagonal column 7 is driven to move in the vertical direction through the reciprocating assembly, thereby changing the relative height between the top-extending octagonal column 7 and the positioning plate 6, so that the top-extending octagonal column 7 can provide a reference point during the loading process, and after the top-extending octagonal column 7 retracts to the positioning plate 6, the existence of the top-extending octagonal column 7 can be avoided from interfering with the unloading process.

[0028] Furthermore, the positioning assembly includes a horizontal slide plate 19 that reciprocates in the horizontal direction, a fixed slide frame 22 is fixedly connected to the base, and a horizontal slide groove is provided on the fixed slide frame 22 for the horizontal movement of the horizontal slide plate 19; The positioning assembly also includes a positioning disk 17 that rotates on a fixed axis on the annular seat 5. The positioning disk 17 is coaxially fixed with the positioning disk 6. The lower surface of the positioning disk 17 is fixedly connected with equidistantly arranged positioning blocks 18, and the cross slide 19 is fixedly connected with horizontally staggered positioning blocks 20 and trapezoidal wedges 21.

[0029] The fixed sliding frame 22 is provided with an orientation frame 24 on the side away from the adjustment plate 17. The orientation frame 24 is fixedly connected to the stamping slide 101. The side of the transverse slide 19 facing the orientation frame 24 is fixedly connected with an orientation pin 23. The orientation frame 24 is provided with an oblique orientation groove 25 for the orientation pin 23 to slide.

[0030] like Figure 1 , Figure 3 , Figure 7 and Fig.11 As shown, when the stamping slide 101 drives the upper die base 2 to move downward, it can synchronously drive the orienting frame 24 to move downward, wherein the orienting pin 23 fixedly arranged on the transverse slide 19 is slidably connected to the orienting frame 24 through the oblique orienting groove 25. Therefore, when the orienting frame 24 moves downward, it can drive the transverse slide 19 and the positioning block 20 and trapezoidal wedge block 21 fixedly arranged thereon to move horizontally in the direction of the adjusting disk 17. During this process, the positioning block 20 is inserted between the two groups of adjusting blocks 18 and slides in contact with the two adjacent groups of adjusting blocks 18. Therefore, under the restriction of the positioning block 20, the adjusting disk 17 and the positioning disk 6 coaxially fixed thereon cannot rotate in the horizontal direction, and then when the upper die base 2 approaches the lower die base 3, the blank disk 4 on the positioning disk 6 will not move.

[0031] At the same time, when the stamping slide 101 drives the upper die seat 2 to move upward, it can drive the cross slide 19 and the fixed positioning block 20 and trapezoidal wedge block 21 thereon to move horizontally away from the adjustment disk 17. At this time, the inclined surface in the trapezoidal wedge block 21 contacts and squeezes the adjustment block 18 at the corresponding position. Since the end of the trapezoidal wedge block 21 facing the adjustment block 18 is an inclined surface, as the trapezoidal wedge block 21 gradually enters the two groups of adjustment blocks 18 and the positioning block 20 separates from the two groups of adjustment blocks 18, the positioning block 20 corresponding to the inclined surface of the trapezoidal wedge block 21 can rotate a certain angle, so that the positioning disk 6 and the blank disk 4 thereon can be driven to rotate synchronously through the adjustment disk 17, thereby changing the relative position of the blank disk 4 to the upper die seat 2 and the lower die seat 3, and then realizing the change of the stamping position during the continuous stamping process, thereby improving the processing efficiency of the stator and rotor punching sheets.

[0032] It should be noted that, in actual use, the single rotation angle of the adjustment plate 17 and the positioning plate 6 is adapted to the angle of adjacent stator slots required to be formed by stamping, so as to meet the processing requirements for the stator and rotor punching sheets.

[0033] Based on the embodiment of the positioning assembly, the re-shifting assembly includes a clearance plate 32 which is arranged on a base and can move freely in the vertical direction. The base is provided with a longitudinal groove for the clearance plate 32 to slide in the vertical direction. A hollow spline shaft 16 is fixedly rotated on the clearance plate 32. The positioning plate 17 is slidably sleeved on the hollow spline shaft 16. One end of the hollow spline shaft 16 away from the clearance plate 32 is fixedly passed through the top extending octagonal column 7.

[0034] A lifting plate 29 is arranged on the base for fixed-axis rotation. The lifting plate 29 includes two sets of side plate portions 292 formed in one piece and a central convex portion 291 between the two sets of side plate portions 292. The position of the yield plate 32 corresponding to the two groups of side plate parts 292 is fixedly connected with a group of connecting rods 33, and one end of the connecting rod 33 facing the side plate part 292 is fixedly connected with a limiting pin 30. The side plate part 292 is provided with a limiting groove 31 for the limiting pin 30 to slide, and the limiting groove 31 includes an inner circular groove part 311 and an outer circular groove part 312 which are integrally formed and connected end to end.

[0035] like Figure 3 and Figure 4 As shown, the lifting disk 29 is driven by a motor fixed on the base to rotate freely in the vertical direction, and the lifting disk 29 that rotates freely in the vertical direction changes the position of the limit groove 31 set on the integrally formed side disk part 292, wherein the limit groove 31 is composed of an integrally formed inner circular groove part 311 and an outer circular groove part 312 connected end to end, and at the same time, the limit pin 30 fixedly set on the connecting rod 33 is slidably connected to the side disk part 292 through the limit groove 31, and a clearance disk 32 is fixedly set on the top of the connecting rod 33, and a hollow spline shaft 16 is fixedly rotated above the clearance disk 32. Therefore, through the rotation process of the lifting disk 29, the limit pin 30 is driven to correspond to the inner circular groove part 311 or the outer circular groove part 312, thereby achieving the purpose of changing the horizontal height of the connecting rod 33, the clearance disk 32 and the hollow spline shaft 16.

[0036] At the same time, the extending octagonal column 7 is fixedly arranged between the hollow spline shaft 16. Therefore, when the blank plate 4 is loaded on the positioning plate 6, the extending octagonal column 7 is exposed outside the positioning plate 6 by a certain length, thereby providing a loading reference point for the blank plate 4. At the same time, the extending octagonal column 7 is retracted to a position below the horizontal height of the positioning plate 6 to avoid the existence of the extending octagonal column 7 hindering the unloading process of the processed parts.

[0037] It should be noted that the adjustment disk 17 is slidably mounted on the hollow spline shaft 16, and the isotropic component used to press and fix the blank disk 4 is arranged on the hollow spline shaft 16. Therefore, when the adjustment disk 17 drives the positioning disk 6 to rotate, it can synchronously drive the isotropic component to rotate through the hollow spline shaft 16, thereby ensuring that no relative displacement occurs between the isotropic component and the blank disk 4, thereby avoiding the phenomenon of position deviation during the stamping process, so as to achieve the purpose of ensuring the stamping accuracy. At the same time, it should be noted that the main function of the base is to support and protect the components arranged thereon. Considering that the design and structure of the base belong to conventional technology in this field, and its specific shape and size will vary according to actual application requirements, it is not shown in the figure.

[0038] Based on the embodiment of the reciprocating assembly, the co-location assembly includes a plurality of groups of pressing seats 8 for fixing the blank plate 4, which are arranged on the top octagonal column 7 and arranged equidistantly, and the plurality of groups of pressing seats 8 move horizontally synchronously toward or away from the central axis of the top octagonal column 7; The pressure seat 8 is provided with a transverse rod 9 on one side of the protruding octagonal column 7. A rectangular through groove is provided on the protruding octagonal column 7 for the transverse rod 9 to slide through. The pressure seat 8 rotates on the transverse rod 9 on a fixed axis. The pressure seat 8 includes an integrally formed end pressure portion 801 and a transverse push portion 802.

[0039] The protruding octagonal column 7 is provided with a isotropic plate 13 which can move freely in the vertical direction. The isotropic plate 13 is in sliding contact with the inner wall of the protruding octagonal column 7. The isotropic plate 13 is fixedly connected with a guide plate 10 corresponding to the transverse rod 9. The transverse rod 9 is fixedly connected with a guide pin 11 on the side facing the guide plate 10. The guide plate 10 is provided with a guide inclined groove 12 for the guide pin 11 to slide. A stop plate 14 is provided below the isotropic plate 13. The stop plate 14 is fixedly connected to the inner wall of the protruding octagonal column 7.

[0040] The lower surface of the same position plate 13 is fixedly connected with a central extension column 15, the bottom end of which passes through the hollow spline shaft 16 and the clearance plate 32 and is provided with an integrally formed ball head end 151, and the ball head end 151 is in sliding contact with the outer peripheral surface of the central convex portion 291; The base is fixedly connected with a side plate 26, and a groove is provided on the side plate 26 for the middle extension column 15 to slide through. The outer peripheral surface of the middle extension column 15 is fixedly connected with an outer ring plate 27, and the outer peripheral surface of the middle extension column 15 is sleeved with a return spring 28, and the two ends of the return spring 28 are respectively abutted and connected to the outer ring plate 27 and the side plate 26.

[0041] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, when the top extending octagonal column 7 moves upward, the set abutment plate 14 can drive the same position plate 13, the guide plate 10, the middle extension column 15 and the pressure seat 8 to rise synchronously, thereby changing the horizontal height of the multiple groups of abutment plates 14 so that it can correspond to the blank plate 4 placed on the positioning plate 6. At the same time, the rise of the middle extension column 15 will drive the reset spring 28 to undergo a certain compression deformation.

[0042] At this time, with the rotation of the lifting plate 29, the limit pin 30 is always in the outer circular groove 312, so the horizontal height of the extended octagonal column 7 will no longer change, but the rotation process of the middle protrusion 291 will further squeeze the ball head end 151 at the bottom of the middle extension column 15, thereby driving the return spring 28 to further compress and deform, so that the middle extension column 15, the isotropic plate 13 and the guide plate 10 move upward relative to the extended octagonal column 7, wherein the guide pin 11 fixedly arranged on the transverse rod 9 is slidably connected to the guide plate 10 through the guide inclined groove 12, therefore, the rising process of the guide plate 10 will gradually drive multiple groups of transverse rods 9 to drive the pressure seat 8 at the end to gradually move away from the central axis of the extended octagonal column 7 for horizontal movement.

[0043] At the same time, the rotor hole in the blank plate 4 is sleeved on the top extended octagonal column 7. Therefore, when multiple groups of pressure seats 8 move in the horizontal direction, the integrally formed transverse pushing portion 802 thereon can contact with the inner wall of the rotor hole and adjust the position of the blank plate 4 in real time until the transverse pushing portion 802 in all the pressure seats 8 are in contact with the inner wall of the rotor hole. At the same time, with the continuous horizontal movement of the transverse rod 9, since the transverse pushing portion 802 is pressed against the inner wall of the rotor hole, the pressure seat 8 is gradually deflected with the movement of the transverse rod 9 until the end pressure portion 801 on the pressure seat 8 is tightly pressed against the upper surface of the blank plate 4.

[0044] During this process, the position of the blank disk 4 can be adjusted by the opposite movement of the transverse rod 9, so that the rotor hole in the blank disk 4 can be aligned with the center axis of the top octagonal column 7, thereby achieving the purpose of determining the processing position of the blank disk 4. At the same time, after the processing position of the blank disk 4 is determined, the end pressure portion 801 can press and fix the blank disk 4 to avoid relative position between it and the positioning disk 6. A torsion spring is provided between the pressure seat 8 and the transverse rod 9 to drive the pressure seat 8 to return to its initial position. The initial state of the pressure seat 8 is a state inclined in the vertical direction. Its purpose is to ensure that when the pressure seat 8 moves horizontally, the end pressure portion 801 can first contact with the blank disk 4 and adjust its processing position, and then press and fix the blank disk 4 through the end pressure portion 801. The torsion spring is an existing device and a technical means well known to technicians in this field, so it is not shown in the figure.

[0045] It should be noted that during the horizontal rotation process, the adjustment disk 17 can drive the center extension column 15 to rotate synchronously horizontally through the hollow spline shaft 16, the top octagonal column 7 and the isotropic plate 13, wherein the ball head end 151 integrally formed at the bottom of the center extension column 15 is in sliding contact with the outer peripheral surface of the center convex portion 291, and the two ends of the return spring 28 are respectively connected to the outer ring plate 27 and the side plate 26. Therefore, the center extension column 15 can rotate freely in the horizontal direction and can change its own horizontal height by rotating the center convex portion 291.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
