Description

Technical Field

[0001] The present invention relates to the field of stator laminations, and specifically to a device for detecting the deformation of a stator lamination during encapsulation and cooling. Background Art

[0002] A stator lamination refers to a structure in which multiple thin sheets (usually silicon steel sheets) are laminated together to form a stator core in the stator component of an electric motor or generator. These thin sheets are typically produced by stamping, shearing, or laser cutting, and then stacked in sequence to form the core part of the stator. Among them, encapsulating the stator lamination of the motor is a key process in motor manufacturing, mainly used for the production of the stator core of the motor. Its purpose is to reduce the eddy current loss during the operation of the motor by encapsulating the surface of the stator core lamination, thereby improving the motor efficiency.

[0003] In the prior art, during the annealing process of encapsulating the stator lamination of the motor, if the temperature is too high, the annealing time is too long, the heating and cooling are uneven, etc., it is possible to cause deformation of the stator lamination. Therefore, it is necessary to detect whether the stator lamination is deformed after the annealing process of encapsulating the stator lamination of the motor. Most of them use laser scanning technology. During the detection process, the staff needs to limit the position of the stator to ensure that the stator does not move during the scanning process. However, when facing a stator with a large size, the staff needs to use a clamping component to manually limit its position. This process reduces the overall detection efficiency, increases the overall workload of the staff, and the light in different areas during the detection process will have a certain impact on the laser scanner, resulting in a reduction in the overall detection accuracy.

[0004] In summary, when facing a stator with a large size, manually limiting the position by the staff reduces the overall detection efficiency, increases the overall workload of the staff, and at the same time, the light will have a certain impact on the laser scanner during the detection process, resulting in a reduction in the overall detection accuracy. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a device for detecting the deformation of a stator lamination during encapsulation and cooling, so as to solve the technical problems that the manual clamping method reduces the overall detection efficiency, increases the overall workload of the staff, and the light in different external areas reduces the overall detection accuracy.

[0006] To achieve the above object, the present invention provides the following technical solution: A stator lamination encapsulation cooling deformation detection device, comprising a workbench and a frame, wherein the frame is located on the top of the workbench. A groove is provided on the top of the workbench, and a driving disk is rotatably arranged in the groove. An elastic placement plate is arranged on the top of the driving disk, and guide posts cooperating with the placement plate are symmetrically arranged in the driving disk. Claws cooperating with the guide posts are arranged on both sides of the placement plate on the top of the driving disk; And one end of the guide post can penetrate through the driving disk and is connected with an arc-shaped tooth block. A fixed gear meshing with the arc-shaped tooth block is rotatably arranged in the sandwich layer of the workbench through the side wall of the groove. A turntable cooperating with the fixed gear is rotatably arranged on the top inside the frame, and a laser scanner body is arranged at the bottom of the turntable.

[0007] By adopting the above technical solution, under the action of the self-gravity of the stator, the insertion rod at the bottom of the placement plate is driven to slide downward, so that the special-shaped gear rotates inward and contacts the outer wall of the stator. In this process, the automatic limit clamping work of the stator is completed. The arc-shaped tooth block will regularly drive the fixed gear to rotate, and cooperate with the transmission mechanism to drive the laser scanner body to adjust its position, so as to realize that every time the driving disk rotates one circle during the detection process, the laser scanner body will perform a certain angle of position adjustment, ensuring that the whole stator is detected at different positions during the whole detection process.

[0008] The present invention is further arranged such that a stepping motor is arranged at the bottom of the workbench, and the output end of the stepping motor is connected to the driving disk, wherein the stepping motor is used to drive the driving disk to rotate.

[0009] Preferably, under the action of the stepping motor, it is convenient for the staff to adjust the rotation speed of the driving disk, so as to facilitate the detection work of stators with different outer diameters, improving the overall practicality of the device.

[0010] The present invention is further arranged such that an insertion rod cooperating with the guide post is arranged at the bottom of the placement plate, and the contact surfaces of the insertion rod and the guide post are both arc-shaped.

[0011] Preferably, when the placement plate slides downward under the action of the self-gravity of the stator, it will drive the bottom insertion rod to move downward accordingly. The arc-shaped end surface of the insertion rod squeezes the arc-shaped end surfaces of the two guide posts on both sides, so that the guide posts will slide to both sides.

[0012] The present invention is further arranged such that fixed tooth blocks are partially arranged at the top of the guide post, and a special-shaped gear meshing with the fixed tooth blocks is connected to the bottom of the claw.

[0013] Preferably, when the guide post slides on both sides under the action of the insertion rod, the fixed tooth block will move accordingly, and under the engagement with the special-shaped gear, it drives the claw to rotate by a certain angle, so that the end face of the claw contacts the outer wall of the stator.

[0014] The present invention is further configured that a rotating shaft is connected to the top of the fixed gear, and the other end of the rotating shaft penetrates through the workbench and is connected to the top inside the frame. The other end of the rotating shaft is connected to a transmission mechanism, and at the same time, the other end of the transmission mechanism is connected to the turntable.

[0015] Preferably, when the fixed gear rotates by a certain angle under the action of the arc-shaped tooth block, the transmission mechanism will be driven to rotate under the action of the rotating shaft, so that the turntable inside the top of the frame rotates accordingly, realizing the position adjustment of the laser scanner body.

[0016] The present invention is further configured that the transmission mechanism includes a driving disk, a transmission belt and a driven disk. The driving disk and the driven disk are connected by the transmission belt. One end of the driving disk is connected to the rotating shaft, and one end of the driven disk is connected to the turntable.

[0017] Preferably, when the rotating shaft rotates through the fixed gear, it will drive the driving disk at one end to rotate. Under the action of the transmission belt, the driven disk will follow to rotate, thereby realizing that during the rotation of the fixed gear, the driven disk will drive the turntable at the bottom to rotate and adjust.

[0018] The present invention is further configured that a mounting plate is provided on the inner wall of the frame, and one end of the rotating shaft penetrates through the mounting plate. At the same time, a reciprocating lead screw is provided in the part inside the mounting plate. A lead screw sleeve plate is slidably arranged on the outer wall of the reciprocating lead screw, and a dust removal component is detachably arranged on one side of the lead screw sleeve plate.

[0019] Preferably, during the process of the driving disk driving the stator to rotate, the reciprocating lead screw will also rotate through the rotating shaft. During this process, the reciprocating lead screw will drive the dust removal component to move under the action of the lead screw sleeve plate, so as to realize adjusting the dust removal component to different positions on the mounting plate, effectively cleaning the dust on the stator, ensuring the uniformity of the laser beam emission of the laser scanner body, and further improving the detection accuracy of the laser scanner body.

[0020] The present invention is further configured that a roller is rotatably arranged inside one end of the claw, and a protective sleeve is wrapped on the outer wall of the roller.

[0021] Preferably, when the end face of the claw contacts the outer wall of the stator, the roller converts the sliding friction between the claw and the stator into rolling friction, which facilitates the staff to easily lift the stator vertically in the vertical direction, facilitating the subsequent hoisting of the stator after the detection is completed. At the same time, the protective sleeve on the outer wall of the roller can prevent the roller from directly contacting the outer wall of the stator, effectively preventing the outer wall of the stator from being worn to a certain extent during the hoisting and sliding of the roller.

[0022] The present invention is further configured such that a compression spring is connected to the bottom of the placement plate, and the other end of the compression spring is connected to the driving disk.

[0023] Preferably, when the staff hoists the stator to the top of the placement plate, the placement plate slides downward driven by the self-gravity of the stator. During this process, the compression spring at the bottom of the placement plate is in a compressed state. After the detection is completed and the stator is hoisted and removed, the placement plate is reset by the reset action of the compression spring. At this time, the claw resets and rotates, facilitating the subsequent normal placement and detection of the stator.

[0024] The present invention is further configured such that a rough surface is provided on the top of the placement plate.

[0025] Preferably, the rough surface is provided to increase the sliding friction between the placement plate and the stator, preventing the stator from shifting in position under slight external vibration.

[0026] In summary, the present invention mainly has the following beneficial effects: In the present invention, a placement plate is elastically provided on the top of the driving disk. By placing the large-sized stator to be detected on the placement plate, then driven by the self-gravity of the stator, the insertion rod at the bottom of the placement plate slides downward, thereby causing the guide posts to slide to both sides. Under the action of the fixed tooth blocks on the guide posts, the special-shaped gear at the bottom of the claw is driven to rotate, causing the special-shaped gear to rotate inward and contact the outer wall of the stator. During this process, the automatic clamping work of the stator is completed, without manual clamping, reducing the overall work burden and improving the overall detection efficiency; In the present invention, a fixed gear is penetrated through the groove of the workbench. During the process of the guide post sliding to one side, the arc-shaped tooth block at one end is driven to engage with the fixed gear. The driving disk is driven to rotate by the stepping motor, and the arc-shaped tooth block regularly drives the fixed gear to rotate, and cooperates with the transmission mechanism to drive the laser scanner body to adjust its position. In this way, every time the driving disk rotates one circle during the detection process, the laser scanner body will perform a certain angle of position adjustment to ensure that the stator is detected as a whole at different positions during the overall detection process. Subsequently, the collected three-dimensional point cloud data will be processed and reconstructed by computer software, effectively improving the overall detection accuracy; In the present invention, a mounting plate is provided inside the frame, and a reciprocating lead screw is provided on the part of the rotating shaft that penetrates through the mounting plate. During the process of the driving disk driving the stator to rotate, the reciprocating lead screw will also rotate through the rotating shaft. During this process, the reciprocating lead screw will drive the dust removal assembly to move under the action of the lead screw sleeve plate, so as to adjust the dust removal assembly to different positions on the mounting plate, effectively cleaning the dust on the stator, ensuring the uniformity of the laser beam emission of the laser scanner body, and further improving the detection accuracy of the laser scanner body.

DETAILED DESCRIPTION OF THE INVENTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation to the present invention.

[0030] The embodiments of the present invention will be described below according to its overall structure.

[0031] The first embodiment: Please refer to Figures 1 - 10 A stator lamination encapsulation cooling deformation detection device, including a workbench 1, a frame 2, a limiting mechanism, a detection mechanism and a sliding mechanism. A groove 10 is opened at the top of the workbench 1, and a driving disk 11 is rotatably arranged in the groove 10. A placement plate 4 is elastically arranged on the top of the driving disk 11. The staff hoists a large-sized stator to be detected onto the top of the placement plate 4. Subsequently, under the action of the self-gravity of the stator, the placement plate 4 will be driven to slide downward. Since a plug rod 14 cooperating with a guide post 13 is arranged at the bottom of the placement plate 4, and the contact surfaces of the plug rod 14 and the guide post 13 are both arc-shaped. When the placement plate 4 slides downward under the action of the self-gravity of the stator, the plug rod 14 at the bottom will be driven to move downward accordingly. The arc-shaped end surface of the plug rod 14 squeezes the arc-shaped end surfaces of the two guide posts 13 on both sides, so that the guide posts 13 will slide to both sides. Moreover, claws 3 cooperating with the guide posts 13 are arranged on both sides of the placement plate 4 at the top of the driving disk 11. A fixed tooth block 19 is partially arranged at the top of the guide post 13, and a special-shaped gear 18 meshing with the fixed tooth block 19 is connected to the bottom of the claw 3. When the guide post 13 slides to both sides under the action of the plug rod 14, the fixed tooth block 19 will move accordingly. Under the meshing with the special-shaped gear 18, the claw 3 is driven to rotate by a certain angle, so that the end surface of the claw 3 contacts the outer wall of the stator. In this process, the automatic limiting and clamping work of the stator is completed, without manual clamping, reducing the overall work burden and improving the overall detection efficiency. At the same time, the output end of the stepping motor 15 is connected to the driving disk 11. Under the action of the stepping motor 15, it is convenient for the staff to adjust the rotation speed of the driving disk 11, so as to facilitate the detection work of stators with different outer diameters. One end of the guide post 13 can penetrate through the driving disk 11 and is connected with an arc-shaped tooth block 16. A fixed gear 12 meshing with the arc-shaped tooth block 16 is rotatably arranged through the side wall of the groove 10 in the interlayer of the workbench 1. When the stator is hoisted to the top of the placing plate 4, the guide post 13 will slide to both sides through the insertion rod 14. During this process, the arc-shaped tooth block 16 at one end of the guide post 13 will mesh with the fixed gear 12. When the stepping motor 15 drives the driving disk 11 to rotate, the arc-shaped tooth block 16 will periodically drive the fixed gear 12 to rotate. Since a rotating shaft 5 is connected to the top of the fixed gear 12, and the other end of the rotating shaft 5 is connected with a transmission mechanism 20, and at the same time, the other end of the transmission mechanism 20 is connected with the turntable 8, and a laser scanner body 9 is arranged at the bottom of the turntable 8; When the fixed gear 12 rotates by a certain angle under the action of the arc-shaped tooth block 16, the transmission mechanism 20 will be driven to rotate under the action of the rotating shaft 5, so that the turntable 8 at the inner top of the frame 2 rotates accordingly, realizing the position adjustment of the laser scanner body 9. In this way, it is realized that every time the driving disk 11 rotates one circle during the detection process, the laser scanner body 9 will perform a position adjustment by a certain angle, ensuring that the stator is detected at different positions during the overall detection process. Subsequently, the collected three-dimensional point cloud data will be processed and reconstructed by computer software, effectively improving the overall detection accuracy.

[0032] In the above embodiment, specifically, please refer to Figure 10 wherein the transmission mechanism 20 includes a driving disk, a transmission belt and a driven disk. The driving disk and the driven disk are connected by a transmission belt. One end of the driving disk is connected with the rotating shaft 5, and one end of the driven disk is connected with the turntable 8. When the rotating shaft 5 rotates through the fixed gear 12, it will drive the driving disk at one end to rotate. Under the action of the transmission belt, the driven disk rotates accordingly, thus realizing that during the rotation of the fixed gear 12, the driven disk drives the turntable 8 at the bottom to rotate and adjust.

[0033] In the above embodiment, specifically, please refer to Figure 6 A compression spring 17 is connected to the bottom of the placing plate 4, and the other end of the compression spring 17 is connected with the driving disk 11. When the staff hoists the stator to the top of the placing plate 4, the placing plate 4 slides down under the action of the self-weight of the stator. During this process, the compression spring 17 at the bottom of the placing plate 4 is in a compressed state. After the detection is completed and the stator is hoisted and removed, under the reset action of the compression spring 17, the placing plate 4 is reset. At this time, the claw 3 resets and rotates, which is convenient for the normal placement and detection of the subsequent stator.

[0034] The second embodiment: Please refer to Figure 9 and Figure 11A stator lamination encapsulation cooling deformation detection device shown in the figure has an overall structure similar to that of the first embodiment. An installation plate 7 is provided on the inner wall of the frame 2, and one end of the rotating shaft 5 penetrates through the installation plate 7. A reciprocating lead screw 21 is provided in the part located within the installation plate 7. A lead screw sleeve plate 22 is slidably arranged on the outer wall of the reciprocating lead screw 21. A dust removal assembly 6 is detachably arranged on one side of the lead screw sleeve plate 22. During the process of the driving disk 11 driving the stator to rotate, the reciprocating lead screw 21 will also rotate through the rotating shaft 5. During this process, the reciprocating lead screw 21 will drive the dust removal assembly 6 to move under the action of the lead screw sleeve plate 22. By the rotation of the dust removal fan blades on the dust removal assembly 6, the dust on the stator is cleaned. In this way, the dust removal assembly 6 is adjusted to different positions on the installation plate 7, effectively cleaning the dust on the stator, ensuring the uniformity of the laser beam emission of the laser scanner body 9, and further improving the detection accuracy of the laser scanner body 9. The specific working principle of the dust removal assembly 6 belongs to the prior art for those skilled in the art, so it is not elaborated in detail in this application.

[0035] The third embodiment: Please refer to Figure 12 A stator lamination encapsulation cooling deformation detection device shown in the figure. On the basis of the second embodiment, a roller 23 is rotatably arranged on the inner side of one end of the claw 3, and a protective sleeve is wrapped around the outer wall of the roller 23. When the end face of the claw 3 comes into contact with the outer wall of the stator, the roller 23 will convert the sliding friction between the claw 3 and the stator into rolling friction, thus facilitating the staff to easily lift the stator vertically in the vertical direction and facilitating the hoisting of the stator after the subsequent detection is completed. At the same time, the protective sleeve on the outer wall of the roller 23 can prevent the roller 23 from directly contacting the outer wall of the stator, effectively preventing the roller 23 from causing a certain degree of wear to the outer wall of the stator during hoisting and sliding.

[0036] When the present invention works specifically: During use, the large-size stator to be detected is hoisted onto the placement plate 4 on the top of the driving disk 11. Under the action of the self-gravity of the stator, the placement plate 4 will be driven to move downward. During this process, the insertion rod 14 at the bottom of the placement plate 4 will slide down and squeeze the guide columns 13 on both sides. At this time, the guide columns 13 will slide to both sides under the action of the insertion rod 14. Since the fixed tooth blocks 19 are partially arranged on the guide columns 13, the fixed tooth blocks 19 will engage with the special-shaped gears 18 at the bottom ends of the claws 3 during the process of sliding to both sides. During this process, the claws 3 are flipped by a certain angle and come into contact with the outer wall of the stator, thereby realizing the limiting clamping of the stator by the claws 3. Subsequently, the driving disk 11 is driven to rotate by the stepping motor 15, and the overall is scanned and detected by the laser scanner body 9, reducing the overall working burden and improving the overall detection efficiency at the same time; And an arc-shaped tooth block 16 is also provided at one end of the guide post 13. When the guide post 13 slides on both sides under the action of the insertion rod 14, the arc-shaped tooth block 16 will slide out of the driving disk 11 and engage with the fixed gear 12 protruding in the groove 10. When the driving disk 11 is driven to rotate by the stepping motor 15, the arc-shaped tooth block 16 will also rotate following the driving disk 11. In this process, it is realized that every time the driving disk 11 rotates one circle, the fixed gear 12 will be driven to rotate a certain angle by the arc-shaped tooth block 16. And with the cooperation of the fixed gear 12 and the transmission mechanism 20, it is realized to drive the laser scanner body 9 to adjust its position by a certain angle, ensuring that the stator as a whole is detected at different positions during the overall detection process (since the working principle of the laser scanner depends on the emission of the laser beam and the reception of the reflected signal, when the detection angle of the laser scanner changes, the laser signal reflected by the target surface will also change. Especially for low-reflection materials or certain special surfaces, the change in the reflection angle may affect the signal intensity received by the laser receiver, thus affecting the accuracy of the data. Therefore, the light at different angles of the laser scanner body 9 will affect the detection result. In order to improve the overall detection accuracy, it is necessary to scan the outer wall of its stator as a whole at different positions), and then the collected three-dimensional point cloud data will be processed and reconstructed by computer software, effectively improving the overall detection accuracy.

[0037] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
