Description

Technical Field

[0001] This invention relates to the field of motor manufacturing technology, specifically to a multi-stage motor stator and rotor assembly and its intelligent assembly platform. Background Technology

[0002] An electric motor is an electromagnetic device that converts mechanical and electrical energy. The stator and rotor assembly is the core component of the electric motor, consisting of a stationary part (stator) and a rotating part (rotor). The two parts work together through the action of a magnetic coil to convert electromagnetic energy into mechanical energy.

[0003] The prior art discloses Chinese patent CN 221574962 U: a quick-release multi-stage stator and rotor assembly, which discloses a limiting shaft, a limiting hole, a limiting plate, a limiting nut, and a screw block. By inserting the limiting shaft into the limiting hole, and cooperating with the limiting plate, the rotating shaft, and the connecting shaft, the connection strength between several rotor plates can be enhanced. Then, several plug rods are inserted into the plug holes, and the limiting nut is threaded onto the side surface of the screw block to fasten the connection between several stator plates.

[0004] However, the aforementioned existing technology still has certain drawbacks. During use, the surface of the stator laminations is easily damaged when the stator laminations are fixed by tightening the limit nuts. Furthermore, each limit nut needs to be operated carefully during disassembly and assembly, resulting in low disassembly and assembly efficiency.

[0005] The prior art also discloses a Chinese patent with publication number CN 110380583 B: a machine for assembling a motor stator and rotor, which discloses a V-shaped adjustable limit frame, a laser position sensor I installed on the V-shaped adjustable limit frame, a stator bracket, and a laser position sensor II installed on the stator bracket. The laser position sensor is used to detect whether the rotor is level during the lifting and lowering process of the V-shaped adjustable limit frame and to measure whether the stator base is level during the swing of the swing arm mechanism.

[0006] However, the aforementioned existing technologies still have certain drawbacks. During use, multiple laser position sensors are required to monitor and control the coaxiality of the motor stator and rotor over time, which is cumbersome and inconvenient for later maintenance.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The stator and rotor assembly of this invention is a core component of an electric motor. Its main function is to convert electrical energy into mechanical energy through electromagnetic induction, and it is widely used in various motor systems.

[0046] The intelligent assembly platform of this invention belongs to the intelligent manufacturing equipment industry and is a part of motor manufacturing equipment. It is used to precisely assemble the rotor core and stator concentrically, and automatically control the anti-loosening mechanism to limit the rotor core and stator after the pre-assembly is completed, thereby improving assembly quality and efficiency.

[0047] Example 1: Refer to the appendix of the instruction manual. Figures 1-2 This embodiment is the first embodiment of the present invention, which provides a multi-stage motor stator and rotor assembly. The assembly includes a shaft 1, a rotor core 2 fixedly sleeved on the outside of the shaft 1, a stator 3 movably sleeved on the outside of the rotor core 2, and an isolation sleeve 4 movably sleeved between the rotor core 2 and the stator 3. In order to improve the heat dissipation efficiency of the stator and rotor assembly during operation, the isolation sleeve 4 can be set as a mesh structure. At the same time, the isolation sleeve 4 can also be used to ensure the coaxiality of the stator and rotor assembly during operation and improve the stability of the motor operation.

[0048] The stator 3 consists of a magnetic yoke and multiple sets of main magnetic poles and multiple sets of commutating poles that are detachably fixed to the inner side of the magnetic yoke by bolts. The main magnetic poles and commutating poles are alternately distributed. The main magnetic poles are connected in series and arranged to make their magnetic polarities alternate. The commutating poles improve commutation by counteracting the armature reaction. In addition, the stator 3 should also have a compensation winding. These windings are embedded in the axial grooves cut in the pole shoes of the main magnetic poles and arranged in a concentric coil pattern. The commutating poles and compensation windings are connected in series with the armature to ensure that their magnetic effect changes proportionally with the load (the above is based on the prior art and will not be described in detail here). Moreover, a T-slot with a sealed end is opened on the magnetic pole core of the commutating pole, and a T-strip is fixed on the outside of the isolation sleeve 4. The T-strip is slidably connected to the corresponding T-slot. The sealed end of the T-slot ensures that the isolation sleeve 4 will not separate during the insertion of the rotor core 2 after being inserted into the stator 3.

[0049] The anti-loosening mechanism 5 includes a locking ring frame 51 fixed at both ends of the rotor core 2, a limiting ring 52 fixed at both ends of the stator 3, and a locking member disposed between the locking ring frame 51 and the limiting ring 52. The locking ring frame 51 located at both ends of the rotor core 2 can be used to clamp and limit multiple core segments that make up the rotor core, and can be fixed by a through screw.

[0050] Furthermore, the locking component includes an annular platform 53 threaded onto both ends of the outer side of the rotating shaft 1, a retaining plate 54 movably inserted into the annular platform 53, a through groove 55 opened on the retaining plate 54, and an annular groove 56 opened on the inner side of the limiting ring 52. The end of the annular platform 53 near the retaining plate 54 is configured as a frustum-shaped structure, and the end of the retaining plate 54 extending into the locking ring frame 51 is fixedly provided with a wedge-shaped block. The screwed-in annular platform 53 can squeeze the wedge-shaped block at the end of the retaining plate 54, pushing the end of the retaining plate 54 located outside the locking ring frame 51 into the annular groove 56 on the limiting ring 52, thus limiting the relative position of the rotor core 2 and the stator 3 after insertion. The through groove 55 ensures that the winding lead-out end installed on the rotor core 2 can smoothly pass through at the position of the retaining plate 54.

[0051] Example 2: Refer to the appendix of the instruction manual. Figure 3 This embodiment is the second embodiment of the present invention, which provides an intelligent assembly platform for a multi-stage motor stator and rotor assembly, used to automatically assemble the stator 3 and rotor core 2 of the multi-stage motor stator and rotor assembly. It includes a frame 6 consisting of a support platform and columns fixed at the four corners of the bottom of the support platform. The stator conveying part 7 and the rotor conveying part 8 are both installed on the support platform.

[0052] Furthermore, such as Figures 4-5 As shown, the stator conveying section 7 consists of a stepping conveying assembly mounted on the frame 6 and multiple brackets 75 fixedly mounted on the stepping conveying assembly. The multiple brackets 75 are equidistantly distributed along the conveying direction of the stepping conveying assembly.

[0053] Furthermore, the stepper conveyor assembly includes two conveyor frames 71 fixed on the support platform. Conveyor rollers 72 are rotatably mounted between both ends of the two conveyor frames 71. One of the conveyor rollers 72 is driven to rotate by a stepper motor mounted on the outside of the conveyor frame 71. This stepper motor uses mature existing technology; the specific model can be selected according to actual production needs and will not be elaborated here. A conveyor belt 73 is wound between the two conveyor rollers 72. A bracket 74 is fixedly installed on the outside of the conveyor belt 73 at the position corresponding to each bracket 75. The bracket 74 corresponding to each bracket 75 is equipped with... There are three supports 74, with the two end supports 74 being higher than the central support 74, which can improve the stability when carrying the stator 3. The bracket 75 is fixedly connected to the top of the central support 74. The top surfaces of the supports 74 at both ends are in contact with the outer side of the bracket 75, which can facilitate the smooth transition of the bracket 75 at the turning point during the conveying process. Each of the two conveying frames 71 has three through holes arranged in a one-to-one correspondence. The setting of this locking component can prevent the locking components from directly contacting the stator 3 and the rotor core 2, thus avoiding scratches on the surface of the parts.

[0054] Furthermore, bracket 75 consists of a V-shaped arc plate and sealing end plates fixed at both ends of the V-shaped arc plate. The sealing end plates can be used to limit the stator 3, so as to avoid the situation where the stator 3 deviates too much from the bracket 75 during the subsequent insertion of the rotor core 2, which would lead to assembly failure.

[0055] It should be noted that before assembling the rotor core 2 into the stator 3, the isolation sleeve 4 needs to be inserted into the stator 3 first. During the conveying process of the stator 3, the conveyor belt 73 is driven by a stepper motor for step-by-step conveying, and the stator 3 with the rotor core 2 to be assembled is placed one by one on the bracket 75 that has moved to the loading position. Then, when the stator 3 with the rotor core 2 to be assembled is transported to the position of the rotor conveying section 8 by the conveyor belt 73, the rotor conveying section 8 can insert the target rotor core 2 into the stator 3.

[0056] Refer to the instruction manual appendix Figures 3-4 The rotor conveying section 8 consists of end piece 1 81 and end piece 2 82 installed on the top of the frame 6, and end piece 1 81 and end piece 2 82 are respectively placed on both sides of the stator conveying section 7.

[0057] Furthermore, such as Figures 6-7As shown, end component 81 includes a cylinder 811 fixed to the top of the support platform. A square column 812 is fixedly connected to the telescopic end of the cylinder 811. A support plate 813 is fixedly mounted on the top of the square column 812. A straight plate 814 is fixedly mounted on the outer side of the square column 812. A cylinder 815 is fixedly mounted on the top of the straight plate 814. A lifting plate 816 is fixedly connected to the telescopic end of the cylinder 815. A buckle plate 817 is fixedly mounted on the bottom of one end of the lifting plate 816, which is directly opposite the support plate 813. The support plate 813 and the buckle plate 817 are connected together. All plates 817 are designed with a V-shaped structure, and both ends of the support plate 813 are provided with notches and slots of equal width to the buckle plate 817. At the same time, a sealing plate is added to the end of the support plate 813 away from the end piece 82. The lifting plate 816 can be pushed downward by the cylinder 815 to make the buckle plate 817 and the support plate 813 fasten together, thereby fastening the corresponding end of the rotating shaft 1. The sealing plate can ensure that the rotor core 2 is inserted into place when the cylinder 811 pushes the square column 812 to transport the rotor core 2.

[0058] End component 81 also includes a T-shaped slide groove 818 formed on the top of the support platform. A π-shaped slide block 819 is slidably connected inside the T-shaped slide groove 818. A V-shaped bracket 8111 with a V-shaped structure is provided on the top of the π-shaped slide block 819. Two movable square sleeves 8110 that are inserted into the top of the π-shaped slide block 819 are fixedly provided at the bottom of the bracket 8111. A spring 8112 is fixedly connected between the π-shaped slide block 819 and the bracket 8111. During the elastic deformation of the spring 8112, the two vertical sections of the π-shaped slide block 819 always maintain... A spring 8116 is fixedly connected between the π-shaped slide block 819 and the inner wall of one end of the T-shaped slide groove 818, and inserted into the corresponding square sleeve 8110. The setting of the spring 8116 can ensure that after each push of the rotor core 2, the support plate 813 can be reset to the initial position (that is, the side of the square column 812 connected to the cylinder 811 is in contact with the inner wall of the corresponding end of the T-shaped slide groove 818, the same below), ensuring that the next round of rotor core 2 feeding process is stable. The bottom end of the square column 812 moves in contact with the bottom end face of the inner cavity of the T-shaped slide groove.

[0059] End component 81 also includes a U-shaped strip 8113 fixed through the square column 812 and side plates 8115 fixed on both sides of the T-shaped slide groove 818 on the top of the support platform. Each of the two side plates 8115 has a limiting groove on its opposite side, directly opposite the U-shaped strip 8113. A limiting block is fixed to the outside of the U-shaped strip 8113 and slidably connected inside the limiting groove. The combination of the limiting groove and the limiting block can be used to assist in limiting the movement of the square column 812, ensuring that the rotor core 2 is advanced in a straight line. The two square sleeves 811... A through groove 8114 is provided at both ends of the U-shaped strip 8113. The through groove 8114 is a parallelogram structure, and both ends of the U-shaped strip 8113 are inclined surfaces. The slope of the inclined surface at the end of the U-shaped strip 8113 is equal to the slope of the inclined surface on the through groove 8114. In addition, when the square column 812 is in the initial position, the high end of the inclined surface on the U-shaped strip 8113 is inserted into the corresponding through groove 8114 and fits against the low end of the lower inclined surface inside the through groove 8114.

[0060] Furthermore, such as Figure 8 As shown, end piece 2 82 includes cylinder 3 822 and square column 2 821 fixed on the top of the support platform. The telescopic end of cylinder 3 822 moves through square column 2 821, and cylinder 3 822 is located inside the through hole centrally located on the conveyor frame 71. The telescopic end of cylinder 3 822 is fixedly connected to an L-shaped frame 823 that moves over the top of square column 2 821. Square column 2 821 can be used to provide auxiliary support for the corresponding end of L-shaped frame 823, thereby improving the stability of L-shaped frame 823 carrying rotor core 2.

[0061] L-shaped frame 823 has a support plate 824 and a pad 825 fixed at one top end. A cylinder 826 is fixed at one top end of the pad 825. A lifting plate 827 is fixedly connected to the telescopic end of the cylinder 826. A buckle plate 828 is fixed at the bottom of one end of the lifting plate 827, which is directly opposite to the support plate 813. The support plate 824 and the buckle plate 828 are both set as V-shaped structures. The middle of both ends of the support plate 824 is also provided with a notch with the same width as the buckle plate 828. The cylinder 826 can be used to push the lifting plate 827 downward to complete the buckle plate 828 and the support plate 824 to achieve the corresponding end of the rotating shaft 1 being fastened.

[0062] End component 2 82 also includes a seat block 829 fixed to the top of the pad plate 825. The outer side of the seat block 829 has three evenly distributed annular grooves. Each of the three grooves has a cylinder 5 8210 fixedly installed inside. The telescopic end of the cylinder 5 8210 is fixedly connected to a U-shaped plate 8211. Multiple equally spaced rollers 8212 are rotatably mounted on the inner side of the U-shaped plate 8211. The central axis of the annular track formed by the three grooves and the connection between the buckle plate 2 828 and the support plate 2... When the center axis of the rotor shaft 1 is horizontally collinear, the buckle plate 817 and the support plate 813 are buckled together to clamp the shaft 1. The synchronously elongating U-shaped plate 8211 can be used to hold the inner wall of the stator 3 to ensure the coaxiality of the rotor core 2 and the stator 3 during the insertion and assembly. The roller 8212 can prevent the U-shaped plate 8211 from directly contacting the inner wall of the stator 3 and reduce the frictional resistance encountered by the U-shaped plate 8211 during the process of exiting the stator 3.

[0063] It should be noted that during the process of inserting the rotor core 2 into the stator 3, firstly, the rotor core 2 to be assembled needs to be placed on the bracket 8111 by a robotic arm, and the corresponding end of the shaft 1 is supported by the initial position of the support plate 813. At this time, under the action of the spring 8112, the shaft 1 is kept horizontal, and the shaft 1 and the rotor core 2 are respectively attached to the support plate 813 and the bracket 8111. Then, the L-shaped frame 823 in the initial state is pulled by the cylinder 822 (see...). Figure 8 As shown, the device moves towards end piece 81, allowing the second support plate 824 to pass through the stator 3 at the corresponding position and move to below the corresponding end of the rotating shaft 1. In this state, the two ends of the rotating shaft 1 are respectively attached to the first support plate 813 and the second support plate 824. Then, the second cylinder 815 and the fourth cylinder 826 respectively drive the corresponding lifting plates to move downward, allowing the corresponding buckle plate to pass through the notch groove on the corresponding support plate to complete the fastening.

[0064] Subsequently, three cylinders 8210 are simultaneously controlled to push the corresponding U-shaped plates 8211 to move in opposite directions until the rollers 8212 installed on the U-shaped plates 8211 are in contact with the inner wall of the stator 3. During this process, the position of the stator 3 can be corrected by using the three synchronously extended U-shaped plates 8211 to ensure that the central axis of the stator 3 and the central axis of the rotating shaft 1 are set horizontally and collinearly. During this process, the stator 3 after the position is corrected does not leave the area corresponding to the sealing end plate. The sealing end plate can be used to limit the stator 3 to ensure that the stator 3 is not misaligned during the insertion of the rotor core 2.

[0065] After the relative position of the stator 3 is corrected, the square column 812 is pushed towards the end piece 82 by cylinder 811. At the same time, cylinder 822 pushes the L-shaped frame 823 away from the end piece 81. During this period, the pushing and feeding amounts of the two are kept synchronized. In addition, during the process of the square column 812 being pushed towards the end piece 82 by cylinder 811, the two ends of the U-shaped bar 8113 continue to be inserted into the corresponding through slot 8114. Then, as the U-shaped bar 8113 is pushed forward, it pushes the square sleeve 8110 downward and compresses the spring 8112, causing the bracket 8111 to separate from the rotor core 2. This ensures that the clamping plate 54 extending to the outside of the locking ring frame 51 can smoothly pass through the area where the bracket 8111 is located during the process of the rotor core 2 being pushed towards the end piece 82, thus completing the pre-assembly of the insertion between the rotor core 2 and the stator 3.

[0066] Example 3: Refer to the appendix of the instruction manual. Figure 1 and Figures 9-10 - Figure 11 This embodiment is the third embodiment of the present invention. This embodiment differs from the second embodiment in that it also includes a screwing mechanism 9 consisting of a first stop block 91 placed on both sides of the stator conveying section 7, a second stop block 92 fixed on the top of the first stop block 91, a through groove 93 opened on the first stop block 91, and a screwing assembly 94 installed inside the through groove 93. The ends of the two first stop blocks 91 and the two second stop blocks 92 near the pre-insertion assembly station of the rotor core 2 and the stator 3 on opposite sides are all set as inclined structures, so as to adjust the relative position of the rotor core 2 and the stator 3 through the corresponding inclined surfaces, ensuring that the clamping plate 54 on the locking ring frame 51 is aligned with the annular groove 56 on the limiting ring 522. The first stop block 91, the second stop block 92, the through groove 93 and the screwing assembly 94 located on the same side together constitute a screwing mechanism unit.

[0067] Furthermore, the screwing assembly 94 includes two round rods fixed inside the corresponding through groove 93, and a swing seat 941 is rotatably sleeved on the outer side of each of the two round rods. The swing seat 941 is configured as a zigzag structure and is intended to be set... Figure 11 The state shown is the initial state, in which the clamping ends of the two swing seats 941 in the initial state are set in a flared shape to ensure that the rotating shaft 1 can smoothly enter the clamping area of ​​the two swing seats 941. A slot 942 is opened on the opposite side of one end of the two swing seats 941, and a buckle 946 is fixedly provided on the opposite side of one end of the two swing seats 941. A cylinder 943 is fixedly provided on the opposite side of one end of the two swing seats 941. A U-shaped frame 944 is fixedly connected to the telescopic end of the cylinder 943. A rotating cylinder 945 is rotatably installed on the inner side of the U-shaped frame 944. The rotating cylinder 945 is driven to rotate by a motor installed on the outer side of the corresponding U-shaped frame 944. An adjusting member is provided between the other ends of the two swing seats 941.

[0068] Furthermore, the adjusting component includes a U-shaped seat 947 fixed to one side of the corresponding stop 91 and an arc groove 9410 opened on the opposite side of the two corresponding swing seats 941. A double extension cylinder 948 is fixedly embedded in the middle of the U-shaped seat 947. Both extension ends of the double extension cylinder 948 are fixedly connected to a ball 949. The two balls 949 are slidably connected inside the corresponding arc groove 9410. The groove opening width of the arc groove 9410 is smaller than the ball diameter of the ball 949, which can ensure that the ball 949 rotates inside the corresponding arc groove 9410 while moving in a stable linear motion along the corresponding arc groove 9410. A rangefinder 9411 is fixedly installed in the middle of the inner side of the U-shaped seat 947.

[0069] It should be noted that during the process of adjusting the insertion of one end of the locking plate 54 on the locking ring frame 51 into the corresponding groove 56 on the limiting ring 52, when the conveyor belt 73 is used to transport the pre-assembled rotor core 2 and stator 3 to the screwing station, as the conveyor belt 73 is conveying, the two ends of the rotating shaft 1 will be guided by the inclined surface on the corresponding stop block 1 91 to complete the fine adjustment of the position of the rotor core 2. At the same time, the two ends of the stator 3 will be guided by the inclined surface on the corresponding stop block 2 92 to complete the fine adjustment of the position of the stator 3. This ensures that the pre-assembled rotor core 2 and stator 3 complete the fine adjustment of their positions before entering the screwing station, that is, so that the end of the locking plate 54 on the locking ring frame 51 extending to the outside is aligned with the groove 56 on the corresponding limiting ring 52.

[0070] After the rotor core 2 and stator 3, having completed their pre-assembly, enter the screwing station, two double-extension cylinders 948 simultaneously push the two balls 949 at their respective positions to move in opposite directions. This causes one end of the corresponding two swing seats 941 with arc grooves 9410 to expand around the circular rod at its center axis, thereby causing the clamping ends of the corresponding two swing seats 941 to engage. The fasteners 946 on opposite sides of the corresponding two swing seats 941 then secure the end of the rotating shaft 1. Finally, the corresponding two swing seats 941... Cylinder 6 943 drives the two U-shaped frames 944 to move in opposite directions, so that the two rotating drums 945 tightly abut against the outer side of the ring platform 53 threaded onto the outer side of the rotating shaft 1. Then, the motor is started to control the two rotating drums 945 to rotate. The rotating drums 945 drive the ring platform 53 to rotate, so that the ring platform 53 rotates along the rotating shaft 1 and pushes the corresponding end of the clamping plate 54 to extend outward and insert into the corresponding ring groove 56 to complete the screwing. In this state, the rotor core 2 and the stator 3 will remain in a state of not being loosened, so as to facilitate the subsequent assembly with the motor housing.

[0071] In the above technical solution, the multiple cylinders mentioned are all single-acting cylinders of model DSA25N200; the double-extension cylinder 948 mentioned is a double-extension rod type ESFD standard cylinder; the rangefinder 9411 mentioned is an industrial-grade laser rangefinder sensor of the MRD2 series, and the specific model is selected according to actual production needs.
