Description

Technical Field

[0001] The invention relates to the technical field of magnetic shoe assembly, in particular to auxiliary equipment for assembling motor magnetic shoes. Background Art

[0002] The general process of the automatic installation machine for magnetic tiles is as follows: First, the rotor core to be pressed into the magnetic tiles is accurately placed at the designated station. Then, the magnetic tile feeding device transports the magnetic tiles to the pressing position one by one according to the preset program. At this time, the high-precision pressure control system starts the pressing mechanism and presses the magnetic tiles smoothly into the corresponding slots of the rotor core at the set pressure and speed. When a piece of magnetic tile is pressed in, the rotor core automatically rotates to the next position to be pressed in, and the above process is repeated until all the magnetic tiles are pressed in.

[0003] Magnetic tiles are key components for generating magnetic fields. Improper installation positions will cause uneven magnetic field distribution inside the motor. The originally symmetrical and uniform magnetic field may be too strong or too weak locally due to the position deviation of the magnetic tiles. This will cause additional magnetic field distortion when the motor is running, causing electromagnetic noise and vibration, which will not only reduce the stability of the motor's operation, but also affect the overall efficiency of the motor. Therefore, before pressing the magnetic tiles in, the positioning of the rotor core is very important. Currently, the positioning of the rotor core is generally done by setting positioning holes on the core and then setting matching positioning pins on the positioning device. This design not only requires an additional hole opening procedure, but also the manual insertion of the rotor core is more laborious and can easily fail to keep up with the machine speed. Summary of the invention

[0004] The object of the present invention is to provide an auxiliary device for assembling motor magnet shoes to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an auxiliary equipment for assembling motor magnetic tiles, comprising a workbench, a magnetic tile feeding mechanism is arranged on the workbench, a magnetic tile pressing mechanism is arranged above the magnetic tile feeding mechanism, a placement plate is arranged below the magnetic tile pressing mechanism, a rotor core positioning mechanism is arranged on the top of the placement plate, and the rotor core positioning mechanism is used to position the rotor core. When the rotor core is located below the magnetic tile pressing mechanism, the magnetic tile pressing mechanism presses the magnetic tiles in the magnetic tile feeding mechanism onto the rotor core.

[0006] Preferably, the rotor core positioning mechanism includes an axial positioning module for axially positioning the rotor core; a radial positioning module for radially positioning the rotor core; and a connecting module for connecting to a servo motor installed at the bottom of the placement plate.

[0007] Preferably, the axial positioning module includes an insertion shaft having a plurality of evenly arranged strip grooves on its side, positioning struts are fixedly inserted in the strip grooves, the bottoms of the positioning struts expand outwardly into strip grooves, and an arc strip is fixed to the bottoms of every two positioning struts.

[0008] Preferably, the radial positioning module includes a positioning column with a base fixed at the bottom thereof and a telescopic block provided on the side wall of the positioning column. The telescopic block can extend from the side wall of the positioning column and be inserted into a keyway in the inner wall of the rotor core to limit the radial position of the rotor core.

[0009] Preferably, the inner diameter of the positioning column is the same as the inner diameter of the rotor core, and the outer diameter of the base is larger than the inner diameter of the rotor core, so as to support the rotor core.

[0010] Preferably, the connecting module includes a connecting column, which is fixed to the bottom of the base. A through hole is opened on the placement plate and a bearing is installed in the hole. The connecting column is inserted into the bearing and the bearing is limited by a retaining spring that is engaged with a groove set on the connecting column. A connecting key is installed on the side wall of the connecting column and is connected to the output shaft of the servo motor through the connecting key.

[0011] Preferably, the magnetic tile pressing mechanism includes a cylinder, the cylinder body of the cylinder is installed on a workbench, the telescopic end of the cylinder is fixedly connected to a connecting stud, a connecting plate is sleeved on the bottom of the connecting stud and the connecting plate is limited by setting a locking nut on the connecting plate, and a pressing plate is integrally formed at the bottom of the connecting plate.

[0012] Preferably, the magnetic tile feeding mechanism includes a feeding frame, in which a plurality of magnetic tiles are arranged and the magnetic tiles are pushed toward a feeding port at the front end of the feeding frame by a push plate, and a push spring is connected between the back of the push plate and the inner wall of the feeding frame.

[0013] Preferably, a rotating cylinder is installed on the workbench, and the driving end of the rotating cylinder is connected to the middle of the placement plate to drive the placement plate to rotate. Two rotor core positioning mechanisms are provided on the placement plate and are respectively located at both ends of the placement plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Accurately position the rotor core

[0016] Reliable axial positioning: Axial precise positioning is achieved through the axial positioning module. Multiple evenly spaced strip grooves are set on the side of the insertion shaft, and the positioning struts are fixedly inserted in the grooves. The bottom of the positioning struts is expanded outward and connected through arc strips. When the rotor core is inserted, the positioning struts and the arc strips are pressed against its inner wall together, which increases the contact area to ensure positioning stability on the one hand, and prevents the positioning struts from being inserted into the keyway by mistake on the other hand, ensuring that the rotor core remains vertically positioned in the axial direction.

[0017] Accurate radial positioning: The inner diameter of the positioning column of the radial positioning module is the same as the inner diameter of the rotor core, and the outer diameter of the base fixed at the bottom is larger than the inner diameter of the rotor core for support. The telescopic block set on the side wall of the positioning column can be extended and inserted into the keyway on the inner wall of the rotor core. After the rotor core is manually rotated to fit the positioning column, the telescopic block automatically snaps into the keyway to achieve complete radial positioning of the rotor core, ensuring accurate installation of the magnetic tile and avoiding problems such as uneven distribution of the motor magnetic field, noise and vibration, and reduced efficiency due to inaccurate positioning.

[0018] 2. Efficient feeding and pressing

[0019] Automatic and convenient feeding: The magnetic tile feeding mechanism adopts a combination of a feeding frame, a push plate and a push spring. Multiple magnetic tiles are arranged in the feeding frame, and the push plate pushes the magnetic tiles to the feeding port under the action of the push spring. When the frontmost magnetic tile is pressed into the rotor core, the push plate can automatically push the subsequent magnetic tiles to the feeding port to wait for pressing in, without the need for frequent manual feeding, which improves feeding efficiency and continuity.

[0020] Stable and controllable pressing: The cylinder of the magnetic tile pressing mechanism is connected to the connecting plate through the connecting studs, and the bottom of the connecting plate is integrally formed with a pressing sheet. The cylinder pushes the connecting plate to drive the pressing sheet to press the magnetic tile from the feeding frame into the rotor core. By adjusting the cylinder pressure and stroke, the force and depth of the magnetic tile pressing can be accurately controlled to ensure the stability of the pressing process and improve the assembly quality of the magnetic tile.

[0021] 3. Improve overall equipment efficiency

[0022] Double-station design improves efficiency: A rotating cylinder is installed on the workbench, and its driving end is connected to the middle of the placement plate. Rotor core positioning mechanisms are set at both ends of the placement plate. The rotor core to be pressed into the magnetic tile can be placed on the positioning mechanism at one end in advance. When the magnetic tile at the other end is pressed in, the rotating cylinder quickly rotates the placement plate to send the new rotor core under the magnetic tile pressing mechanism, reducing the time the equipment waits for manual placement of the rotor core, significantly improving the overall work efficiency of the equipment.

DETAILED DESCRIPTION

[0031] 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 implementation regulations described 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.

[0032] Embodiment 1

[0033] refer to Figure 1-2 The present invention is an auxiliary device for assembling motor magnetic tiles, comprising a workbench 1, on which a magnetic tile feeding mechanism 3 is arranged, a magnetic tile pressing mechanism 2 is arranged above the magnetic tile feeding mechanism 3, a placement plate 4 is arranged below the magnetic tile pressing mechanism 2, a rotor core positioning mechanism 6 is arranged on the top of the placement plate 4, and the rotor core positioning mechanism 6 is used to position the rotor core 7. When the rotor core 7 is located below the magnetic tile pressing mechanism 2, the magnetic tile pressing mechanism 2 presses the magnetic tiles in the magnetic tile feeding mechanism 3 onto the rotor core 7.

[0034] Since multiple magnetic tiles need to be pressed into the rotor core 7, the installation position of the magnetic tiles needs to be very accurate. The magnetic tiles are the key components for generating the magnetic field. If the installation position is inaccurate, the magnetic field distribution inside the motor will be uneven. The originally symmetrical and uniform magnetic field may be too strong or too weak locally due to the position deviation of the magnetic tiles. This will cause additional magnetic field distortion during the operation of the motor, causing electromagnetic noise and vibration, which will not only reduce the stability of the motor's operation, but also affect the overall efficiency of the motor. Whether the installation position of the magnetic tiles is accurate is closely related to the positioning of the rotor core 7. Only when the rotor core 7 is accurately positioned can the pressed magnetic tiles be accurately positioned. Therefore, a rotor core positioning mechanism is designed, and its specific structure is as follows:

[0035] refer to Figure 5 The rotor core positioning mechanism 6 includes an axial positioning module 61 for axially positioning the rotor core 7; a radial positioning module 62 for radially positioning the rotor core 7; and a connecting module 63 for connecting to the servo motor 8 installed at the bottom of the placement plate 4.

[0036] The axial positioning module 61 includes an insertion shaft 611, and a plurality of evenly arranged strip grooves 612 are opened on the side of the insertion shaft 611. A positioning strut 613 is fixedly inserted in the strip groove 612. The strip groove 612 is expanded outward from the bottom of the positioning strut 613. An arc strip 614 is fixed to the bottom of every two positioning struts 613. The rotor core 7 is inserted from the insertion shaft 611. The positioning strut 613 and the arc strip 614 jointly press against the inner wall of the rotor core 7, so that the rotor core 7 can maintain vertical positioning in the axial direction. The arc strip 614 has the following functions: on the one hand, it increases the contact area with the rotor core 7, and on the other hand, it prevents the positioning strut 613 from being inserted into the key slot 9 in the inner wall of the rotor core 7, so that the rotor core 7 cannot be axially positioned.

[0037] The radial positioning module 62 includes a positioning column 621, a base 623 is fixed at the bottom of the positioning column 621, and a telescopic block 622 is provided on the side wall of the positioning column 621. The telescopic block 622 can extend from the side wall of the positioning column 621 and be inserted into the keyway 9 in the inner wall of the rotor core 7 to limit the radial position of the rotor core 7. The inner diameter of the positioning column 621 is the same as the inner diameter of the rotor core 7, and the outer diameter of the base 623 is larger than the inner diameter of the rotor core 7, which is used to support the rotor core 7. When the inner hole of the rotor core 7 fits the positioning column 621, the rotor core 7 is completely positioned in the axial direction. The rotor core 7 is manually rotated, and when a click is heard, the telescopic block 622 is inserted into the keyway 9 in the rotor core 7, and the rotor core 7 is also completely positioned in the radial direction, so that the positioning work of the rotor core has been completed.

[0038] The connection module 63 includes a connection column 631, which is fixed to the bottom of the base 623. A through hole is provided on the placement plate 4 and a bearing is installed in the hole. The connection column 631 is inserted into the bearing and is clamped into the clamping groove 632 provided on the connection column 631 by a clamping spring 634 to limit the bearing. A connection key 633 is installed on the side wall of the connection column 631, and is connected to the output shaft of the servo motor 8 through the connection key 633. The rotor core positioning mechanism 6 is driven to rotate by the servo motor 8, and then the rotor core 7 is driven to rotate. Since the magnetic tile is not completely pressed into the rotor core 7 at one time, the servo motor 8 needs to rotate to achieve multiple pressing of the magnetic tile.

[0039] refer to Figure 4 The magnetic tile feeding mechanism 3 includes a feeding frame 31, in which a plurality of magnetic tiles are arranged and pushed to a feeding port 34 at the front end of the feeding frame 31 by a push plate 33, and a push spring 32 is connected between the back of the push plate 33 and the inner wall of the feeding frame 31. When the frontmost magnetic tile is pressed in from the feeding port 34, the push plate 33 pushes the rear magnetic tile to the feeding port 34 under the elastic force of the push spring 32 to wait for subsequent pressing into the rotor core 7.

[0040] refer to Figure 3 The magnetic tile pressing mechanism 2 includes a cylinder 21, the cylinder body of the cylinder 21 is installed on the workbench 1, the telescopic end of the cylinder 21 is fixedly connected with a connecting stud 22, a connecting plate 23 is sleeved at the bottom of the connecting stud 22, and a locking nut is set on the connecting plate 23 to limit the connecting plate 23, and a pressing sheet 24 is integrally formed at the bottom of the connecting plate 23. The cylinder 21 pushes the connecting plate 23 to drive the pressing sheet 24 to press the magnetic tile in the feeding frame 31 into the rotor core 7.

[0041] Furthermore, a rotary cylinder 5 is installed on the workbench 1, and the driving end of the rotary cylinder 5 is connected to the middle of the placement plate 4, which is used to drive the placement plate 4 to rotate. Two rotor core positioning mechanisms 6 are provided on the placement plate 4, and are respectively located at both ends of the placement plate 4. This design allows the rotor core 7 to be pressed into the magnetic tile to be placed on the rotor core positioning mechanism 6 in advance. After the magnetic tile at the other end is pressed in, the rotary cylinder 5 rotates the placement plate 4 to send the rotor core 7 under the magnetic tile pressing mechanism 2, so that the equipment does not need to wait for manual insertion of the rotor core 7, thereby improving work efficiency.

[0042] 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.
