DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0022] The stator-rotor assembly of the present application is a core component of a motor, which mainly functions to convert electrical energy into mechanical energy through electromagnetic induction and is widely applied in various motor systems.

[0023] The intelligent assembly platform of the present invention belongs to a type of intelligent manufacturing equipment industry and is a part of motor manufacturing equipment. It is used to precisely and concentrically assemble the rotor core and stator, and automatically control the anti-loosening mechanism to limit the rotor core and stator that have been pre-assembled, thereby improving assembly quality and efficiency.

[0024] Example 1: Refer to the attached instructions Figure 1-Figure 2 This embodiment is the first embodiment of the present invention, which provides a multi-stage motor stator and rotor assembly, including a rotating shaft 1. A rotor core 2 is fixedly sleeved on the outside of the rotating shaft 1, a stator 3 is movably sleeved on the outside of the rotor core 2, and an isolation sleeve 4 is 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 to 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, thereby improving the stability of the motor operation. Among them, the stator 3 is composed of a yoke and multiple groups of main poles and multiple groups of commutator poles that are detachably fixed to the inner side of the yoke by bolts. The main poles and the commutator poles are alternately distributed, and the main poles are connected in series and arranged so that their magnetic polarity alternates. The commutator poles improve commutation by offsetting the influence of armature reaction. In addition, a compensating winding should be provided inside the stator 3. These windings are embedded in the axial slots cut in the pole shoes of the main poles and arranged in a concentric coil pattern. The commutator poles and the compensating windings are connected in series with the armature to ensure that their magnetic effects change proportionally with the load (the above is for reference to the existing technology and will not be described in detail here). In addition, a T-slot with a sealed end is provided on the magnetic pole core of the commutator pole, and a T-bar is fixed on the outside of the isolation sleeve 4. The T-bar is slidably connected to the corresponding T-slot. The sealed end of the T-slot ensures that after the isolation sleeve 4 is inserted into the stator 3, it will not be separated during the insertion of the rotor core 2. 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 arranged 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 the multiple groups of core segments that make up the rotor core, and fix them by means of a penetrating screw.

[0025] Further, the locking member comprises ring tables 53 threadedly sleeved on both ends of the rotating shaft 1, clamping plates 54 movably inserted into the ring tables 53, through slots 55 formed on the clamping plates 54, and ring slots 56 formed on the inner side of the limiting ring 52, wherein the end of the ring table 53 close to the clamping plate 54 is provided in a circular table structure, and the end of the clamping plate 54 extending into the inside of the locking ring frame 51 is fixedly provided with a wedge-shaped block, the clamping plate 54 can be pushed to the inside of the ring slot 56 on the limiting ring 52 by using the ring table 53 screwed in to extrude the wedge-shaped block at the end of the clamping plate 54, thereby limiting the relative position of the rotor core 2 and the stator 3 after the rotor core 2 and the stator 3 are inserted, and the through slots 55 can ensure that the winding lead end installed on the rotor core 2 can smoothly pass through at the position of the clamping plate 54.

[0026] Embodiment 2: refer to the description attached Figure 3 This embodiment is a second embodiment of the present application, which provides an intelligent assembly platform for a multi-stage motor stator-rotor assembly, which is used for automatically assembling the stator 3 and the rotor core 2 of the multi-stage motor stator-rotor assembly, and comprises a rack 6 composed of a bearing table and columns fixedly installed at the four corners of the bottom of the bearing table, a stator conveying part 7 and a rotor conveying part 8 are both installed on the bearing table.

[0027] Further, as shown in Figure 4-Figure 5 the stator conveying part 7 is composed of a stepping conveying assembly installed on the rack 6 and a plurality of carriers I 75 fixedly installed on the stepping conveying assembly, and the plurality of carriers I 75 are equidistantly distributed along the conveying direction of the stepping conveying assembly.

[0028] Further, the stepping conveying assembly comprises two conveying frames 71 fixedly installed on the bearing table, and conveying rollers 72 rotatably installed between the two ends of the two conveying frames 71, wherein one of the conveying rollers 72 is driven to rotate by a stepping motor installed on the outer side of the conveying frame 71, the stepping motor is a mature prior art, and the specific model can be selected according to actual production, which will not be described here, and a conveying belt 73 is wound between the two conveying rollers 72, and supports 74 are fixedly installed on the outer side of the conveying belt 73 corresponding to the position of each carrier I 75, wherein three supports 74 corresponding to each carrier I 75 are provided, and the supports 74 at both ends are higher than the support 74 arranged in the middle, which can improve the stability when the stator 3 is carried, and the carrier I 75 is fixedly connected to the top of the support 74 arranged in the middle, and the top end faces of the supports 74 at both ends are flush with the outer side of the carrier I 75, which can smoothly transition the inflection point position of the carrier I 75 during conveying, and three through holes corresponding to the carriers I 75 are formed on the two conveying frames 71, wherein the arrangement of the locking member can avoid direct contact between the related parts of the locking and the stator 3 and the rotor core 2, thereby avoiding scratching the surface of the parts.

[0029] Furthermore, the bracket 75 is composed of a V-shaped arc plate and sealed end plates fixed at both ends of the V-shaped arc plate. The sealed end plates can be used to limit the stator 3 to avoid assembly failure caused by the stator 3 deviating significantly from the bracket 75 during the subsequent insertion of the rotor core 2.

[0030] It should be noted that before the rotor core 2 is assembled into the stator 3, the isolation sleeve 4 needs to be inserted into the stator 3 first. In the process of conveying the stator 3, the conveyor belt 73 is driven by a stepper motor to perform step-by-step transportation, and the stators 3 of the rotor core 2 to be assembled are placed one by one on the bracket 75 moved to the loading position by a robot. Then, when the stator 3 of the rotor core 2 to be assembled is transported to the position of the rotor conveying part 8 along the conveyor belt 73, the rotor conveying part 8 is used to insert the target rotor core 2 into the stator 3.

[0031] Refer to the instruction manual Figure 3-Figure 4 The rotor conveying part 8 is composed of an end piece 1 81 and an end piece 2 82 installed on the top of the frame 6 , and the end piece 1 81 and the end piece 2 82 are respectively placed on both sides of the stator conveying part 7 .

The plates 817 are all configured as V-shaped structures, and notches equal in width to the gusset plate 817 are opened in the middle of both ends of the support plate 813. At the same time, a sealing plate is added to the end of the support plate 813 away from the end piece 82. The cylinder 815 can be used to push the lifting plate 816 downward to allow the gusset plate 817 to be fastened with the support plate 813, thereby fastening the corresponding ends of the rotating shaft 1. The sealing plate can ensure that the rotor core 2 is inserted into place during the process of using the cylinder 811 to push the square column 812 to transport the rotor core 2. The end piece 1 81 further includes a T-shaped slot 818 opened on the top of the supporting platform, and a π-shaped slide 819 is slidably connected inside the T-shaped slot 818. A V-shaped bracket 2 8111 is provided on the top of the π-shaped slide 819. Two movable vehicles are fixedly provided at the bottom of the bracket 2 8111, and the square sleeve 8110 on the top of the π-shaped slide 819 is plugged into the bottom of the π-shaped slide 819. A spring 1 8112 is fixedly connected between the π-shaped slide 819 and the bracket 2 8111. In the process of elastic deformation of the spring 1 8112, the two vertical sections of the π-shaped slide 819 are always kept straight. Inserted into the corresponding square sleeve 8110, a spring 2 8116 is fixedly connected between the π-shaped slide 819 and the inner wall of one end of the T-shaped slide 818. The setting of the spring 2 8116 can ensure that each time the rotor core 2 is pushed, the support plate 1 813 can be reset to the initial position (that is, the side of the square column 1 812 connected to the cylinder 1 811 is in contact with the inner wall of the corresponding end of the T-shaped slide 818, the same below), ensuring that the loading process of the next round of the rotor core 2 is stable, and the bottom end of the square column 1 812 is in contact with the bottom end surface of the T-shaped slide cavity for movement; The end piece 81 also includes a U-shaped bar 8113 fixed on the square column 812 in a through-type manner and side plates 8115 fixed on the top of the supporting platform on both sides of the T-shaped slide groove 818. The two side plates 8115 are provided with a limiting groove facing the U-shaped bar 8113 on the opposite sides. A limiting block slidably connected to the inside of the limiting groove is fixed on the outside of the U-shaped bar 8113. The limiting groove and the limiting block can be used in conjunction with each other to assist in limiting the movement of the square column 812 to ensure that the rotor core 2 is pushed in a straight line. The two square sleeves 811 0, there are through grooves 8114 at the positions corresponding to the two ends of the U-shaped bar 8113, wherein the through groove 8114 is set as a parallelogram structure, and the two ends of the U-shaped bar 8113 are set as inclined structures, and the inclined surface at the end of the U-shaped bar 8113 has the same slope as 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 bar 8113 is inserted into the corresponding through groove 8114 and fits with the low end of the inclined surface at the lower end of the through groove 8114.

[0033] Furthermore, if Figure 8 As shown, the second end piece 82 includes a third cylinder 822 and a second square column 821 fixed to the top of the supporting platform. The telescopic end of the third cylinder 822 movably passes through the second square column 821, and the third cylinder 822 is located inside the through hole centrally provided on the conveying frame 71. The telescopic end of the third cylinder 822 is fixedly connected to an L-shaped frame 823 movably overlapped on the top of the second square column 821. The second square column 821 can be used to provide auxiliary support for the corresponding end of the L-shaped frame 823, thereby improving the stability of the L-shaped frame 823 in carrying the rotor core 2. The top of one end of the L-shaped frame 823 is fixed with a supporting plate 2 824 and a pad 825, and one end of the top of the pad 825 is fixed with a cylinder 4 826, and the telescopic end of the cylinder 4 826 is fixedly connected to the lifting plate 2 827, and the bottom of one end of the lifting plate 2 827 is fixed with a gusset plate 2 828 facing the supporting plate 1 813, wherein the supporting plate 2 824 and the gusset plate 2 828 are also both configured as a V-shaped structure, and the middle part of both ends of the supporting plate 2 824 is also provided with a notch groove equal to the width of the gusset plate 2 828, and the cylinder 4 826 can be used to push the lifting plate 2 827 downward to complete the buckling of the gusset plate 2 828 and the supporting plate 2 824, thereby fastening the corresponding ends of the rotating shaft 1; The second end piece 82 also includes a seat block 829 fixed on the top of the pad 825. The outer side of the seat block 829 is provided with three annular evenly distributed sink grooves. The inside of the three sink grooves is fixed with a cylinder 5 8210. The telescopic end of the cylinder 5 8210 is fixedly connected to a U-shaped plate 8211. The inside of the U-shaped plate 8211 is rotatably mounted with multiple rollers 8212 distributed at equal distances. Among them, the central axis of the annular track surrounded by the three sink grooves and the second gusset plate 828 and the second support plate are connected. When 824 is fastened together and the buckle plate 1 817 and the support plate 1 813 are fastened together to clamp the rotating shaft 1, the central axis is arranged horizontally and collinearly. The synchronously extended U-shaped plate 8211 can be used to support the inner wall of the stator 3 to ensure the coaxiality of the rotor core 2 and the stator 3 during plug-in assembly. The setting of the roller 8212 can prevent the U-shaped plate 8211 from directly contacting the inner wall of the stator 3 and reduce the friction resistance encountered by the U-shaped plate 8211 during the process of withdrawing from the interior of the stator 3.

[0034] It should be noted that, in the process of inserting the rotor core 2 into the stator 3, first, the rotor core 2 to be assembled needs to be placed on the second bracket 8111 by a manipulator, and the corresponding end of the rotating shaft 1 is supported by the first support plate 813 in the initial position. At this time, under the action of the first spring 8112, the rotating shaft 1 is kept horizontal, and the rotating shaft 1 and the rotor core 2 are respectively connected to the first support plate 813 and the second bracket 8111. Then, the L-shaped frame 823 in the initial state is pulled by the third cylinder 822 (see Figure 8 As shown in the figure, the first end piece 81 is moved in the direction of the first end piece 81, so that the second support plate 824 passes through the stator 3 at the corresponding position and moves to the bottom of the corresponding end of the rotating shaft 1. In this state, the two ends of the rotating shaft 1 are respectively connected to the first support plate 813 and the second support plate 824. Then, the corresponding lifting plate is driven downward by the second cylinder 815 and the fourth cylinder 826, so that the corresponding buckle plate passes through the notch on the corresponding support plate to complete the buckle engagement. Subsequently, the three cylinders 8210 are simultaneously controlled to synchronously 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 three synchronously extended U-shaped plates 8211 can be used to complete the position correction of the stator 3, ensuring that the central axis of the stator 3 and the central axis of the rotating shaft 1 are arranged horizontally and collinearly. During this period, the stator 3 after the correction 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 does not deviate during the insertion of the rotor core 2. After completing the correction of the relative position of the stator 3, the cylinder 1 811 is used to push the square column 1 812 to move toward the end piece 2 82. At the same time, the cylinder 3 822 will push the L-shaped frame 823 to move away from the end piece 1 81. During this period, the push feed amount of the two keeps changing synchronously. In the process of using the cylinder 1 811 to push the square column 1 812 to move toward the end piece 2 82, the two ends of the U-shaped bar 8113 will continue to be inserted into the corresponding passage groove 8114. Then, as the U-shaped bar 8113 is pushed forward, the U-shaped bar 8113 will push the square sleeve 8110 to move downward and compress the spring 1 8112, so that the bracket 2 8111 is separated from the rotor core 2, ensuring that the rotor core 2 extends to the outside of the locking ring frame 51 in the process of being pushed toward the end piece 2 82. The clamping plate 54 can smoothly pass over the area where the bracket 2 8111 is located, completing the pre-assembly of the plug-in between the rotor core 2 and the stator 3.

[0035] Example 3: Refer to the attached instructions Figure 1 and Figure 9-10 - Figure 11 This embodiment is the third embodiment of the present invention. What is different from the second embodiment is that it also includes a screwing mechanism 9 composed of a stopper 91 disposed on both sides of the stator conveying part 7, a stopper 92 fixed on the top of the stopper 91, a through slot 93 opened on the stopper 91, and a screwing assembly 94 installed inside the through slot 93. Among them, the ends of the opposite sides of the two stoppers 91 and the two stoppers 92 close to the pre-insertion assembly station of the rotor core 2 and the stator 3 are both set as inclined structures, so as to adjust the relative positions 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 limit ring 522. The stopper 91, the stopper 92, the through slot 93 and the screwing assembly 94 on the same side together constitute a screwing mechanism unit.

[0036] Furthermore, the screw assembly 94 includes two round rods fixed inside the corresponding through slots 93, and the outer sides of the two round rods are rotatably sleeved with a swing seat 941, wherein the swing seat 941 is set to a broken line structure, and is intended to be set Figure 11The state shown is the initial state, so that the clamping ends of the two pendulum 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 pendulum seats 941, and slots 942 are provided on the opposite sides of one end of the two pendulum seats 941, and buckle seats 946 are fixed on the opposite sides of one end of the two pendulum seats 941, and cylinder six 943 is fixed on the opposite sides of one end of the two pendulum seats 941, and the telescopic ends of cylinder six 943 are fixedly connected to U-shaped frames 944, and a rotating drum 945 is rotatably installed on the inner side of the U-shaped frame 944, and the rotating drum 945 is driven to rotate by a motor installed on the outer side of the corresponding U-shaped frame 944, and an adjusting part is provided between the other ends of the two pendulum seats 941.

[0037] Furthermore, the adjusting part includes a U-shaped seat 947 fixed on one side of the corresponding stop block 91 and an arc groove 9410 opened on the opposite side of the corresponding two swing seats 941. The middle part of the U-shaped seat 947 is fixedly embedded with a double-extension cylinder 948 in a through-type manner. The two telescopic ends of the double-extension cylinder 948 are fixedly connected with balls 949. The two balls 949 are slidably connected to the corresponding arc groove 9410. The groove diameter width of the arc groove 9410 is smaller than the ball diameter of the ball 949. While ensuring that the ball 949 rotates inside the corresponding arc groove 9410, it can perform 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.

[0038] It should be noted that, in the process of adjusting the end of the clamping plate 54 on the locking ring frame 51 extending to the outside thereof to be inserted into the annular groove 56 on the corresponding limiting ring 52, when the rotor core 2 and the stator 3 that have been pre-assembled and plugged in are transported to the screwing station by the conveyor belt 73, as the conveying process of the conveyor belt 73 proceeds, the two ends of the rotating shaft 1 will be guided by the inclined surfaces on the corresponding stopper 91 during the conveying process 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 surfaces on the corresponding stopper 2 92 during the conveying process to complete the fine adjustment of the position of the stator 3, ensuring that the rotor core 2 and the stator 3 that have been pre-assembled and plugged in are finely adjusted before entering the screwing station, that is, the end of the clamping plate 54 on the locking ring frame 51 that extends to the outside thereof is aligned with the annular groove 56 on the corresponding limiting ring 52. After the pre-assembled rotor core 2 and stator 3 are plugged in and enter the screwing station, two double-extension cylinders 948 will be used to simultaneously push the two balls 949 at the corresponding positions to move in opposite directions, so that one end of the arc groove 9410 of the corresponding two pendulum seats 941 will expand with the round rod at the corresponding position as the central axis, so that the clamping ends of the corresponding two pendulum seats 941 will engage with each other, and the buckle seats 946 on the opposite sides of the corresponding two pendulum seats 941 will complete the support and fixation of the end of the rotating shaft 1, and then, through the corresponding two pendulum seats 941 on the opposite sides of the buckle seats 946, the two pendulum seats 941 will be tightened. Cylinder six 943 pushes the two U-shaped frames 944 to move toward each other, so that the two rotating cylinders 945 are tightly against the outside of the ring platform 53 that is threadedly sleeved on the outside of the rotating shaft 1, and then the motor is started to control the two rotating cylinders 945 to rotate. The rotating rotating cylinder 945 is used to drive the ring platform 53 to rotate, so that the ring platform 53 is screwed in along the rotating shaft 1, and the corresponding end of the clamping plate 54 is pushed outward and inserted 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 loose, thereby facilitating the subsequent assembly with the motor housing.

[0039] In the above technical solution, the multiple cylinders mentioned all use single-acting cylinders with model DSA25N200; the double-extension cylinder 948 mentioned uses a double-extension rod type ESFD standard cylinder; the rangefinder 9411 mentioned uses an MRD2 series industrial-grade laser ranging sensor, and its specific model is selected according to actual production needs.
