Description

Technical Field

[0001] The invention relates to the technical field of motor processing, and in particular to a shaping device for processing motor stator and rotor iron cores. Background Art

[0002] During the motor manufacturing process, the processing quality of the stator and rotor cores plays a vital role in the performance of the motor. The stator and rotor cores in the prior art are usually made of multiple layers of metal sheets laminated and bonded together. In order to ensure its dimensional accuracy, shape accuracy and the close fit of the internal metal sheets, a shaping device is usually required to perform shaping processing on the stator and rotor cores during the processing of the motor.

[0003] When working, traditional motor stator and rotor core shaping devices often simply apply extrusion pressure to the core through an extrusion mechanism to achieve the purpose of shaping. During the extrusion force application process, due to the lack of effective positioning restrictions on the stator and rotor cores, many metal sheets in the stator and rotor cores are in a relatively free state. When subjected to top-down extrusion pressure, the internally bonded metal sheets are prone to deflection due to uneven force, which has a relatively serious impact on the shaping effect of the motor stator and rotor cores, and is likely to lead to an increase in the defective rate and production cost during the processing of the motor stator and rotor cores, affecting the overall production efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, by driving a plurality of positioning rods to move synchronously and setting the top view cross section of the positioning rods to a prismatic structure, a plurality of positioning rods can be engaged in the grooves provided on the stator and rotor cores from the outside or from the inside, and by rotating and toggling the support frame, convenient and accurate positioning restrictions can be performed for stator and rotor cores of different models and sizes, which can effectively improve the application scope of the device, and in the state of positioning restriction, a top-down extrusion force is applied to the stator and rotor cores to complete the shaping operation, which can avoid the metal sheets bonded inside the stator and rotor cores of the motor from being deflected by force during the extrusion shaping, and to a certain extent improve the effect of the stator and rotor cores of the motor after being pressed and shaped;

At the same time, by fixing the spline rod on the driving shaft of the first servo motor, and fixing the first bevel gear on the spline sleeve slidably sleeved on the outer side of the lower end of the spline rod, the meshing of the spur gear and the rack makes it possible to drive the third servo motor to adjust the first bevel gear up and down, and flexibly adjust the meshing state of the first bevel gear and the plurality of second bevel gears, so as to avoid the rotation of the support frame interfering with the position movement of the positioning rod, and to a certain extent improve the stability of the device during adjustment and use;

[0020] 3.

At the same time, by opening the cavity on the machine platform and setting the bracket to a structure extending outward from the middle position, the longer positioning rods will not be blocked during the downward movement, which is convenient for all-round restricted positioning of the stator and rotor cores through a large number of positioning rods, which is conducive to ensuring the comprehensive accuracy of positioning during the extrusion and shaping of the stator and rotor cores;

[0021] 4. In the present invention, the first magnet is fixedly embedded at the bottom end of the positioning rod, and the second magnet that magnetically repels the first magnet is evenly distributed in the bracket, so that when the positioning rod moves downward, under the magnetic repulsion between the first magnet and the second magnet, the bracket is driven to automatically rotate and stagger, automatically avoiding the conflict with the upper positioning rod, which can effectively improve the stability of the positioning rod when it moves downward to position and restrict the stator and rotor cores;

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0044] Embodiment: This embodiment provides a shaping device for machining the stator and rotor core of a motor, see Figure 1 - Fig.12 Specifically, the machine platform 1 includes a support arm 101 fixedly mounted on the top of the machine platform 1, and a vertically arranged hydraulic push rod 102 is fixedly mounted on the front end of the support arm 101, a carrying plate 2 is fixedly mounted on the telescopic end below the hydraulic push rod 102, and a circular plate 201 symmetrically arranged up and down is rotatably mounted at the bottom center of the carrying plate 2, and each circular plate 201 is fixedly mounted with a symmetrically arranged support frame 202, and two support frames 202 fixedly connected to the same circular plate 201 are in the same straight line, and each support frame 202 has a A screw rod 203 is rotatably installed, and a slide 204 is slidably installed in each support frame 202, and the slide 204 is threadedly screwed with the corresponding screw rod 203, and a vertically arranged positioning rod 205 is fixedly installed at the bottom of the slide 204, and a first bevel gear 206 is rotatably installed between the upper and lower disks 201, and a second bevel gear 207 meshing with the first bevel gear 206 is fixed at the end of the four screw rods 203, and a first servo motor 208 for driving the first bevel gear 206 to rotate is fixedly installed in the carrier plate 2.

[0045] When the device is used, the motor stator and rotor core to be shaped is composed of a plurality of metal sheets bonded together. The staff places the motor stator and rotor core just below the carrier plate 2 on the machine table 1, and then controls the carrier plate 2 to move downward through the hydraulic push rod 102. Driven by the downward movement of the carrier plate 2, a plurality of positioning rods 205 are driven to move downward synchronously. When the bottom of the carrier plate 2 does not apply a top-down extrusion force to the stator and rotor core below, the first servo motor 208 is powered on and started to drive the first bevel gear 206 to rotate. With the meshing transmission of the first bevel gear 206 and a plurality of second bevel gears 207, the second bevel gear 207 is driven to drive the corresponding screw rod 203 to rotate. Then, with the threaded meshing of the screw rod 203 and the corresponding slide 204, the slide 204 drives the corresponding positioning rod 205 to move, and the position of the positioning rod 205 is adjusted so that the positioning rod 205 is engaged in the groove on the stator and rotor core.

[0046] During actual operation, the device can operate in two different modes according to the different positions of the grooves evenly distributed around the stator and rotor cores. When mode 1 is enabled, the grooves for winding the coils on the stator and rotor cores to be shaped are opened on the outside. In this state, the positioning rods 205 are located at the end of the corresponding support frame 202 away from the disk 201. When the carrier disk 2 drives the positioning rods 205 to move downward, many positioning rods 205 are distributed on the outside of the stator and rotor cores. Then, driven by the first servo motor 208, many positioning rods 205 move synchronously toward the central axis of the disk 201, and finally engage in the grooves opened on the outside of the stator and rotor cores, thereby positioning the many metal sheets constituting the stator and rotor cores from the outside.

[0047] When mode two is enabled, the groove for winding the coil is opened on the inner side of the stator and rotor core to be shaped. In this state, the positioning rod 205 is located at one end of the corresponding support frame 202 close to the disc 201. When the carrier disc 2 drives the positioning rod 205 to move downward, many positioning rods 205 are vertically inserted in the hollow area on the inner side of the stator and rotor core. Then, driven by the first servo motor 208, many positioning rods 205 move synchronously in the direction away from the disc 201, and finally engage in the groove opened on the inner side of the stator and rotor core, thereby realizing the positioning of many metal sheets constituting the stator and rotor core from the inside.

[0048] During the movement of the positioning rod 205, since the upper and lower discs 201 are both rotatably installed at the bottom of the supporting disc 2, the support frame 202 fixedly connected to the disc 201 can be rotated, so that the staff can adjust the position of the corresponding positioning rod 205 by turning the support frame 202, and finally the many positioning rods 205 are accurately and stably engaged in the grooves on the outside of the stator and rotor cores. The top-view cross-section of the positioning rod 205 is set to a diamond structure, which enables the positioning rod 205 to be engaged in the groove. By moving and squeezing, the extrusion force limit can be applied to the stator and rotor cores more stably, thereby ensuring the positioning accuracy of many metal sheets.

[0049] When the stator and rotor cores are positioned and restricted by the numerous positioning rods 205, the hydraulic push rod 102 continues to start, controlling the carrying plate 2 to continue to move downward, and finally applying a top-down extrusion force to the stator and rotor cores. When the stator and rotor cores are restricted by the numerous positioning rods 205, the top-down extrusion force is stably applied to complete the shaping of the stator and rotor cores. When the shaping is completed, the numerous positioning rods 205 move in the opposite direction to release the positioning of the stator and rotor cores, and the carrying plate 2 is lifted upward under the control of the hydraulic push rod 102 to release the squeezing of the stator and rotor cores. At this time, the staff can take out the shaped stator and rotor cores.

[0050] The device drives a plurality of positioning rods 205 to move synchronously, and sets the top-view cross-section of the positioning rods 205 to a prismatic structure, so that the plurality of positioning rods 205 can be engaged in the grooves provided on the stator and rotor cores from the outside or from the inside, and can be conveniently and accurately positioned for stator and rotor cores of different models and sizes by rotating and toggling the support frame 202. In the positioning state, a top-down extrusion force is applied to the stator and rotor cores to complete the shaping operation, which can effectively improve the application scope of the device, and can prevent the metal sheets bonded inside the motor stator and rotor cores from being deflected by force during the extrusion shaping, and can effectively improve the effect of the motor stator and rotor cores after being pressed and shaped.

[0051] In the specific implementation process, Figure 3 , Figure 4 , Fig.10 and Fig.11 As shown, coaxially arranged toothed rings 3 are fixedly mounted on the end walls of the upper and lower disks 201 that are close to each other, a first bevel tooth 301 is meshedly connected between the upper and lower toothed rings 3, a second servo motor 303 is fixedly mounted in the carrier disk 2, the first bevel tooth 301 is rotatably mounted on the bottom of the carrier disk 2, a coaxially arranged second bevel tooth 302 is fixedly mounted on one side of the first bevel tooth 301, and a third bevel tooth 304 meshing with the second bevel tooth 302 is fixedly mounted on the driving shaft of the second servo motor 303.

[0052] When the device is in use, the driving shaft of the second servo motor 303 does not have a self-locking property, and the staff can control the rotation of the support frame 202 by turning it. Since the driving shaft of the second servo motor 303 does not have a self-locking property, it will not affect the turning and rotation of the support frame 202. Similarly, the staff can also drive the support frame 202 to rotate and adjust through the second servo motor 303. In this mode, the second servo motor 303 is powered on and started, driving the third bevel gear 304 fixedly connected to its driving shaft to rotate, and the rotational power is transmitted to the first bevel gear 301 by means of the meshing of the third bevel gear 304 and the second bevel gear 302, and then the upper and lower disks 201 are driven to rotate synchronously relative to each other under the meshing of the first bevel gear 301 and the upper and lower gear rings 3, thereby driving The support frames 202 connected to the upper and lower disks 201 are rotated and adjusted. By controlling the rotation direction of the second servo motor 303 driving shaft, the rotation directions of the two pairs of support frames 202 can be adjusted, and finally the positions of the plurality of positioning rods 205 can be flexibly adjusted. The staff can choose a suitable method to adjust the positioning rods 205 according to the actual use situation, and the operation is flexible and convenient. When controlling the rotation adjustment of the support frames 202 connected to the two disks 201, since the upper and lower disks 201 are fixed with tooth rings 3 meshing with the first bevel teeth 301, the rotation of the upper and lower disks 201 is synchronous and relative, which can effectively improve the efficiency of the rotation deflection angle adjustment of the support frames 202 connected to the upper and lower disks 201.

[0053] In the specific implementation process, Figure 4 , Figure 7 and Fig.11 As shown, a box body 4 is fixedly installed in the carrier plate 2, and a vertically arranged spline rod 401 is rotatably installed in the box body 4, a spline sleeve 402 is movably sleeved on the outer side of the lower end of the spline rod 401, and the inner size of the spline sleeve 402 is adapted to the outer size of the spline rod 401, the first bevel gear 206 is coaxially fixedly connected with the spline sleeve 402, a square cylinder 403 that can be lifted up and down is slidably installed in the box body 4, and the square cylinder 403 is rotatably connected with the spline sleeve 402, a third servo motor 404 is fixedly installed in the carrier plate 2, a spur gear 405 is rotatably installed in the box body 4, and the spur gear 405 is fixedly installed on the driving shaft of the third servo motor 404, and a rack 406 meshing with the spur gear 405 is vertically fixed on the square cylinder 403.

[0054] When the device is in use, in the process of using the first servo motor 208 to provide power for the rotation of the first bevel gear 206, the first servo motor 208 is powered on and started, which will drive the spline rod 401 fixedly connected to its drive shaft to rotate, and the spline sleeve 402 sleeved on the outside thereof is driven to rotate synchronously through the rotation of the spline rod 401, thereby providing power for the rotation of the first bevel gear 206. When the support frame 202 is toggled to adjust the position of the positioning rod 205, in order to avoid the rotation of the support frame 202 causing the relative meshing rotation of the first bevel gear 206 and the plurality of second bevel gears 207, resulting in the position of the positioning rod 205 being offset, the first bevel gear 206 and the plurality of second bevel gears 207 can be disconnected during the toggling adjustment process of the support frame 202. The gear 207 is meshed, and a rotation sensor is installed between the carrier plate 2 and the disc 201 to detect the rotation of the support frame 202. When the support frame 202 is driven to drive the disc 201 to rotate relative to the carrier plate 2, the rotation sensor transmits the corresponding signal to the processor installed in the machine 1, which will automatically control the third servo motor 404 to be powered on and started. After the third servo motor 404 is powered on and started, it will drive the spur gear 405 fixedly installed on its drive shaft to rotate, and with the help of the meshing of the spur gear 405 and the rack 406, the square tube 403 is driven to drive the spline sleeve 402 to move upward, and finally the first bevel gear 206 connected to the lower end of the spline sleeve 402 moves upward and separates from the numerous second bevel gears 207 below.

[0055] When the support frame 202 is rotated and adjusted to a predetermined deflection angle, the rotation sensor between the carrier disk 2 and the disc 201 cannot detect a rotation signal, and the drive shaft of the third servo motor 404 rotates in the opposite direction, controlling the spline sleeve 402 to drive the first bevel gear 206 to move downward and reset, so that it re-engages with the plurality of second bevel gears 207, driving the positioning rod 205 to continue to move along the support frame 202 and engage in a groove opened on the stator and rotor cores. A pressure sensor is installed between the positioning rod 205 and the slide 204 to detect the extrusion pressure applied by the positioning rod 205 in the groove on the stator and rotor cores. When the extrusion pressure is sufficient, the first servo motor 208 is controlled to stop driving the positioning rod 205, and the operation is flexible and efficient.

[0056] In the specific implementation process, Figure 3 - Figure 4 , Figure 6 , Fig. 9 and Fig.10As shown, the bottom of the disc 201 located below is rotatably connected to a plurality of mutually hinged pressure rods 5, the bottoms of the plurality of pressure rods 5 are in the same horizontal plane, the top of the pressure rod 5 is vertically fixed with a plurality of evenly distributed pillars 501, and the top of the pillar 501 is rotatably mounted with a ball 502, the ball 502 is tightly fitted with the bottom end wall of the supporting disc 2, when the device is used, when the supporting disc 2 is driven downward by the hydraulic push rod 102, the pressure rod 5 hinged at the bottom of the disc 201 will press on the top of the stator and rotor cores, because the bottoms of the plurality of pressure rods 5 are in the same horizontal plane , a pressing surface can be formed by a plurality of pressure rods 5, which effectively increases the contact area between the device and the top of the stator and rotor core when applying a downward extrusion force to the stator and rotor core, thereby facilitating the force stability of the stator and rotor core when being extruded and shaped. At the same time, by hingedly installing a plurality of pressure rods 5 on the bottom of the lower disk 201, the plurality of pressure rods 5 can be rotated to adjust their positions, so that the presence of the plurality of pressure rods 5 will not interfere with the rotation and swing of the support frame 202 and the movement and adjustment of the positioning rod 205, and can ensure the stability of the device during operation to a certain extent.

[0057] By evenly fixing many vertically arranged pillars 501 on the pressure rod 5, and using the pillars 501 to support the bottom of the supporting plate 2 and the pressure rod 5, the stability of the many pressure rods 5 when applying extrusion pressure to the top of the stator and rotor core can be effectively guaranteed, and by rolling the ball 502 on the top of the pillar 501, the friction resistance between the top of the pillar 501 and the bottom of the supporting plate 2 can be greatly reduced, which is beneficial to ensuring the smoothness and convenience of the pressure rod 5 when rotating and adjusting relative to the bottom of the supporting plate 2.

[0058] In the specific implementation process, Figure 2 , Figure 5 , Figure 6 and Fig.10 As shown, the top of the machine 1 is provided with a cavity 6 located just below the supporting plate 2, and a column 601 located just below the disc 201 is vertically fixed at the inner center position of the cavity 6, the top of the column 601 is rotatably connected to a bracket 602, and the top of the bracket 602 is flush with the top of the machine 1, and the bottom of the bracket 602 is fixedly installed with a support block 603 that slides and fits on the cylindrical surface of the column 601, and the support block 603 is arranged as a triangular structure.

[0059] During the use of the device, the shape of the bracket 602 can be set to a cross shape, a cross shape, or the like according to actual use requirements, and the structure extends outward from the middle position. When the stator and rotor cores are shaped and extruded, the stator and rotor cores will be placed on the top of the bracket 602 by the staff. Due to the existence of the concave cavity 6 and the hollow setting of the bracket 602, the positioning rod 205 can be inserted into the concave cavity 6 during the downward movement of the positioning rod 205 driven by the carrier plate 2, so that the positioning rod 205 used for positioning and limiting the numerous metal sheets in the stator and rotor cores can be set to be long enough. During the extrusion and shaping of the stator and rotor cores by the device, the numerous surrounding positioning rods 205 can comprehensively position and limit the metal sheets in the stator and rotor cores from top to bottom, which is conducive to ensuring the comprehensive stability of the positioning during the extrusion and shaping of the stator and rotor cores.

[0060] During the extrusion molding process, by rotating the bracket 602 to be installed on the top of the column 601, the posture of the bracket 602 can be adjusted by rotation, which can avoid the collision between the positioning rod 205 and the bracket 602 during the downward movement, which is beneficial to ensuring the operating stability of the device. At the same time, by fixing the support block 603 with a triangular structure on the bottom of the bracket 602 and sliding it on the cylindrical surface of the column 601, a stable support can be formed for the bracket 602, which is beneficial to improving the stability of the bracket 602 supporting the bottom of the stator and rotor core during the extrusion molding process.

[0061] In the specific implementation process, Fig.12 As shown, a first magnet 604 is fixedly installed at the bottom end of the positioning rod 205, and a plurality of evenly distributed second magnets 605 are fixedly installed in the bracket 602, and the top of the second magnet 605 magnetically repels the bottom end of the first magnet 604. When the device is in use, since the bracket 602 is rotatably installed on the top end of the column 601, the first magnet 604 is fixedly embedded in the bottom end of the positioning rod 205, and the second magnets 605 magnetically repelling the first magnet 604 are evenly distributed in the bracket 602, so that when the positioning rod 205 is moving downward, if the position of the bracket 602 conflicts with the bottom end of the positioning rod 205, the bracket 602 can be driven to rotate automatically under the magnetic repulsion of the first magnet 604 and the second magnet 605, and automatically avoid the conflict with the upper positioning rod 205, so that the operation of the device is more convenient and flexible during actual use.

[0062] In the specific implementation process, Figure 8As shown, the bracket 602 is provided with an evenly distributed airflow channel 606, and the top of the bracket 602 is provided with a plurality of evenly distributed spray holes 607, and the spray holes 607 are connected to the airflow channel 606. When the device is used, the airflow channel 606 is externally connected to an air pump, and a high-speed airflow can be filled into the airflow channel 606 through the external air pump, and then the airflow is sprayed from the many evenly distributed spray holes 607 on the top of the bracket 602 to form an airflow jet from bottom to top. When the stator and rotor cores are placed on the bracket 602 to cover part of the spray holes 607, this The airflow ejected from some of the spray holes 607 can form an airflow layer between the stator and rotor cores and the bracket 602, thereby reducing the contact friction between the stator and rotor cores and the bracket 602, and making it convenient for the staff to adjust the position of the stator and rotor cores placed on the bracket 602. The remaining unshielded spray holes 607 will spray high-speed airflow from bottom to top on the inner and outer sides of the stator and rotor cores. This airflow can not only clean the stator and rotor cores with air blowing, but also accelerate the curing speed of the adhesive in the stator and rotor cores, which is beneficial to improving the quality of the stator and rotor cores after extrusion and shaping.

[0063] Specifically, the working principle and operation method of the present invention are as follows:

[0064] The staff places the stator and rotor core to be shaped on the bracket 602, and the external air pump provides high-speed airflow to the airflow channel 606. The airflow is ejected upward through the nozzle 607 to form an airflow layer between the stator and rotor core and the bracket 602, thereby reducing the friction resistance between the stator and rotor core and the bracket 602, making it convenient for the staff to adjust the stator and rotor core. Synchronously, the stator and rotor core can be cleaned under the blowing of the airflow, and then the staff controls the carrier plate 2 to move downward through the hydraulic push rod 102. According to the structure of the stator and rotor core, many positioning rods 205 are covered on the inner side or outer side of the stator and rotor core. During the downward movement of the positioning rod 205, with the help of the rotation of the bracket 602 and the magnetic repulsion between the first magnet 604 and the second magnet 605, the positioning rod 205 and the bracket 602 are automatically staggered. Then, the staff starts the first servo motor 208 to drive the first bevel gear 206 to rotate. With the meshing of the first bevel gear 206 and the plurality of second bevel gears 207, as well as the meshing of the screw 203 and the slide 204, the plurality of positioning rods 205 are driven to move synchronously and engage in the grooves surrounding the stator and rotor cores to realize the positioning of the plurality of metal sheets in the stator and rotor cores. To ensure that the positioning rods 205 can be accurately engaged in the grooves on the stator and rotor cores, the staff can toggle or drive the support frame 202 to rotate and adjust. After the positioning rods 205 form a positioning limit on the stator and rotor cores, the staff continues to start the hydraulic push rod 102 to control the carrier plate 2 to move downward, so that the pressure rod 5 is pressed on the stator and rotor cores to apply a top-down extrusion force. After the extrusion is completed, the shaping operation of the stator and rotor cores is completed.

[0065] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
