Description

Technical Field

[0001] The utility model relates to the technical field of motor processing devices, and particularly relates to a stator core housing pressing device. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system and belongs to an auxiliary motor indirect variable speed device. It can convert a voltage signal into torque and speed to drive a control object. The rotor speed of the servo motor is controlled by an input signal and can respond quickly. It has characteristics such as a small electromechanical time constant, high linearity, and starting voltage. Its working principle can be simply summarized as: input control signal → servo controller → servo motor → output motion. The servo system consists of a servo motor, a servo controller, and a feedback device. When the servo motor receives a pulse signal, it will rotate by an angle corresponding to the pulse, thereby achieving displacement.

[0003] The structure of the servo motor mainly consists of components such as a stator, a rotor, and an encoder. Among them, the stator of the servo motor is usually formed by several iron cores being tightly held and fixed to each other, and two-phase or three-phase windings are embedded in the surface slots. These windings are used to generate a rotating magnetic field. The rotor is the rotating part of the servo motor, and its structure is related to the type of the motor. For a permanent magnet servo motor, the rotor is usually composed of permanent magnets, and these permanent magnets rotate in the magnetic field generated by the stator.

[0004] Servo motors are widely used in many fields, such as industrial automation, electronic equipment, transportation, printing and packaging, and robotics. They have the advantages of high precision, high speed, strong adaptability, good stability, short dynamic response time, and good comfort. However, in the production process of servo motors, manually assembling the stator core into the housing is mostly adopted. This method not only highly depends on labor, resulting in increased production costs, but also has low production efficiency.

[0035] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0036] As Figure 1 and Figure 2 shown, this solution provides a stator core pressing housing device, including a frame assembly 1. On the surface of the table board 101 of the frame assembly 1, there are provided a housing loading mechanism 2, a housing transfer mechanism 3, a housing heating mechanism 4, a pressing housing mechanism 6, and a stator core loading mechanism 7.

[0037] The housing transfer mechanism 3 includes transfer guide rails 301 arranged in parallel on the table board 101. Two transfer guide rails 301 are respectively provided with matching transfer sliders 302. On the top of the transfer slider 302, there is a housing carrier 303. On the housing carrier 303, there is a housing fixing position 304, and a housing carrier through groove 305 is opened at the axial center position of the housing fixing position 304. On any of the transfer guide rails 301, there is a housing linear module 306. The slider of the housing linear module 306 is connected to the housing carrier 303, and the housing linear module 306 can drive the housing carrier 303 to move linearly.

[0038] Specifically, driven by the housing linear module 306, the housing carrier 303 can drive the housing 8 placed at its housing fixing position 304 to be preheated by the housing heating mechanism 4, and then enter the working area of the pressing housing mechanism to complete the pressing connection with the stator core 9, thereby realizing the pressing of the stator core 9 into the housing 8.

[0039] The housing loading mechanism 2 is used to load the housing onto the housing fixing position 304.

[0040] The housing heating mechanism 4 is used to preheat the housing 8 on the housing fixing position 304.

[0041] The stator core loading mechanism 7 is used to load the stator core 9 onto the pressing housing mechanism 6.

[0042] The pressing housing mechanism 6 includes a housing upper pressing component 601 and a housing lower pressing component 602 arranged vertically. The housing lower pressing component 602 is used to receive the stator core 9 from the stator core loading mechanism 7. Under the interaction of the housing upper pressing component 601 and the housing lower pressing component 602, the housing 8 and the stator core 9 are pressed together.

[0043] The frame assembly 1 includes a frame 102, the table top panel 101 and a door panel 103. After the frame 102, the table top panel 101 and the door panel 103 are interconnected, they form an installation cabinet, and a pneumatic device is arranged inside the installation cabinet to control the operation of each functional mechanism in this system.

[0044] As Figure 4 shown, in this embodiment, the casing loading mechanism 2 includes a robotic arm 202 provided on the table top panel 101 and having a casing gripper 201. Under the drive of the robotic arm 202, the coordinate position of the casing gripper 201 is adjusted, thereby realizing the gripping of the casing 8 on the external casing code disc, and then under the drive of the robotic arm 202, the casing 8 is displaced to the casing fixing position 304 on the casing carrier 303 to complete the loading of the casing 8;

[0045] In addition, in this embodiment, the casing loading mechanism 2 can also grip and unload the completed product after the casing 8 and the stator core 9 are crimped.

[0046] As Figure 6 shown, in order to ensure that the casing 8 can be fixed in the correct position and posture on the casing fixing position 304, in this embodiment, a casing secondary positioning mechanism 5 is arranged on the table top panel 101. The casing secondary positioning mechanism 5 includes a positioning seat 501 fixedly connected to the table top panel 101. A first limit stop 502 and a second limit stop 503 capable of limiting both sides of the casing 8 are arranged on the positioning seat 501. The first limit stop 502 and the second limit stop 503 are arranged at an angle, and a positioning cylinder 504 is further arranged on the positioning seat 501 corresponding to the angle. A casing push claw 505 capable of pushing the other two sides of the casing 8 is arranged at the piston end of the positioning cylinder 504.

[0047] Specifically, the casing loading mechanism 2 places the casing 8 on the positioning seat 501. The positioning cylinder 504 drives the casing push claw 505 to push the casing 8 to the first limit stop 502 and the second limit stop 503. There is a laser sensor in front of the casing 8, which irradiates the hole in front of the casing 8 to prevent the wrong direction of the casing 8 during manual loading. When the laser sensor irradiates the hole, if there is no signal, it means the direction is correct and the next action can be taken, that is, loading the casing 8 to the casing fixing position 304; when the laser sensor irradiates the casing and there is a signal, it means the direction is wrong, and the casing gripper 201 automatically rotates the casing under the drive of the robotic arm 202 until the direction of the casing 8 is correct.

[0048] As Figure 2 and Figure 3As shown in the figure, in this embodiment, the casing heating mechanism 4 includes a heating upper jaw assembly 401 and a heating lower jaw assembly 402 that can interact with each other, and a heating host 403 for heating control;

[0049] A heating through groove 404 is formed in the table board 101 corresponding to the two transfer guide rails 301. The heating upper jaw assembly 401 is arranged above the heating through groove 404, and the heating lower jaw assembly 402 is arranged below the heating through groove 404.

[0050] In this embodiment, when the casing fixing position 304 drives the casing 8 to shift to the heating through groove 404, the heating lower jaw assembly 402 works, penetrates the casing 8 through the heating through groove 404 and the casing carrier through groove 305, and then the heating upper jaw assembly 401 descends to contact the heating lower jaw assembly 402, and the heating host 403 works to complete the preheating of the casing 8.

[0051] After the preheating is completed, the heating upper jaw assembly 401 and the heating lower jaw assembly 402 return to their respective positions, and the casing fixing position 304 drives the preheated casing 8 to shift to the casing pressing mechanism 6.

[0052] Specifically, the heating upper jaw assembly 401 includes an upper jaw bracket 405 arranged on the table board 101. An upper jaw cylinder 406 is arranged at the top of the upper jaw bracket 405, and a heating upper jaw 407 is connected to the piston end of the upper jaw cylinder 406;

[0053] The heating lower jaw assembly 402 includes a lower jaw bracket 408 arranged on the back of the table board 101. A lower jaw electric cylinder 409 is arranged at the bottom end of the lower jaw bracket 408, and a heating lower jaw 410 is connected to the piston end of the lower jaw electric cylinder 409;

[0054] The heating upper jaw 407 and the heating lower jaw 410 are respectively controlled for heating by the heating host 403. Specifically, the heating host 403 generates a magnetic field, and the heating upper jaw 407 and the heating lower jaw 410 are used for magnetic conduction, so that the casing is in a closed magnetic field to generate an induced current and then heat up. The heating upper jaw 407 and the heating lower jaw 410 are only in contact with the subsequent host. When heating, the heating host 403 generates a magnetic field, and the upper and lower jaws will be attracted to the host. When not working, the upper and lower jaws can slide relative to the host.

[0055] It should be noted that in this embodiment, the heating upper jaw 407, the heating lower jaw 410, and the heating through groove 404 are coaxial. When the housing fixing position 304 drives the housing 8 to shift to the position of the heating through groove 404, the heating upper jaw 407, the housing 8, the housing carrier table through groove 305, the heating through groove 404, and the heating lower jaw 410 are coaxial. This structure can ensure uniform preheating of the housing 8.

[0056] When heating housings 8 of different models, the lower jaw electric cylinder 409 lifts the heating lower jaw 410 to the height corresponding to the housing 8, and then the upper jaw cylinder 406 drives the heating upper jaw 407 to descend until it contacts the heating lower jaw 410, and then heating is carried out.

[0057] As Figure 3 and Figure 5 As shown in

[0058] Specifically, the housing pressing-down assembly 602 includes a housing pressing-down bracket 606 arranged at the bottom of the table board 101. The bottom end of the housing pressing-down bracket 606 is provided with a housing pressing-down electric cylinder 607. The piston end of the housing pressing-down electric cylinder 607 is connected with a stator core carrier 608. The housing pressing-down electric cylinder 607 can drive the stator core carrier 608 to move up and down along the stator core through groove 610.

[0059] The housing pressing-up assembly 601 includes a housing pressing-up bracket 603 arranged on the table board 101. The top end of the housing pressing-up bracket 603 is provided with a housing pressing-up electric cylinder 604. The piston end of the housing pressing-up electric cylinder 604 is provided with a housing pressing head 605.

[0060] When the housing fixing position 304 drives the housing 8 to shift to the housing carrier 303, the housing pressing-up electric cylinder 604 drives the housing pressing head 605 to move downward until it presses on the top of the housing 8;

[0061] The housing pressing-down electric cylinder 607 drives the stator core carrier 608 to move upward along the stator core through groove 610 and extends into the cavity of the housing 8 through the housing carrier table through groove 610 to complete the crimping.

[0062] As Figure 2As shown in the figure, in this embodiment, the stator core loading mechanism 7 includes a stator core loading bracket 701 disposed on the surface of the table board 101. A loading translation execution module 702 is arranged on the stator core loading bracket 701. A loading lifting execution module 703 is connected to the slider of the loading translation execution module 702. A stator core gripper 704 is arranged on the slider of the loading lifting execution module 703.

[0063] The stator core gripper 704 is driven by the loading lifting execution module 703 to perform vertical lifting, and the stator core gripper 704 is driven by the loading translation execution module 702 to perform translation, so as to realize loading the external stator core 9 onto the stator core carrier 608.

[0064] The above is only to illustrate the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
