Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor stator tooling, in particular to a motor stator assembly tooling. Background Art
[0002] In the field of motor manufacturing, the installation process of the motor stator usually requires precise positioning and press-fitting of the stator. Traditional motor stator assembly equipment generally consists of a fixed seat and a movable seat structure, and the stator is clamped and installed through a mechanical or hydraulic system. Generally, the stator installation process of these traditional devices is relatively simple, relying on manual operation and fixed fixtures to complete the adjustment of the stator position and press-fit. However, due to the limitations of the structural design, these devices have certain difficulties in achieving precise clamping and automatic centering, resulting in low installation efficiency and difficulty in meeting the needs of production environments requiring high precision and high consistency.
[0003] Traditional motor stator assembly tooling generally utilizes fixed slots or parallel clamping structures. This design lacks automatic centering during the clamping process, which can easily lead to stator offset and inaccurate positioning during installation. Since automatic centering is not possible, operators often need to repeatedly manually adjust the stator position, increasing the complexity of the operation. Furthermore, the press-fitting process of traditional tooling is mostly manual and lacks automated devices. This not only reduces work efficiency but also may affect the quality and stability of the stator installation due to human error. Therefore, traditional solutions have significant deficiencies in clamping accuracy, degree of automation, and operational efficiency, and cannot fully meet the requirements of modern production.
[0004] In view of this, research and improvement are carried out on the existing problems, and a motor stator assembly tool is provided to solve the current problems. The purpose is to achieve the purpose of solving the problems and improving the practical value through this technology. Utility Model Content

DETAILED DESCRIPTION
[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.
[0025] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.
[0026] The following is combined with Figure 1-Figure 5 A motor stator assembly tool provided in some embodiments of the present invention is described. Example 1
[0027] In this embodiment, the specific structure of the motor stator assembly tool of the present invention includes: a tool base 100, a tool control assembly 200, and a clamping rod assembly 300. A turntable 110 is rotatably mounted on the surface of the tool base 100; the tool control assembly 200 comprises a fixed guide plate 210, a rotating guide plate 220, and a plurality of movable sleeves 230. The fixed guide plate 210 is fixedly mounted on the surface of the turntable 110, while the rotating guide plate 220 is rotatably mounted on the top surface of the fixed guide plate 210. The fixed guide plate 210 and the rotating guide plate 220 are respectively provided with a first guide groove 211 and a second guide groove 221. These structures are used to slide the movable sleeves 230 therein, thereby enabling radial movement of the movable sleeves 230.
[0028] The clamping rod assembly 300 includes a drive box 310, a lifting rod 320, and a rotation-limiting plate 330. The rotation-limiting plate 330 is fixedly mounted on the bottom surface of the drive box 310 and slidably sleeved on the outside of the lifting rod 320. A worm motor 311 is fixedly mounted on the surface of the drive box 310 and cooperates with the lifting rod 320 via a worm gear reel 312 to achieve the lifting and lowering motion of the lifting rod 320. Specifically, the worm motor 311 engages with the worm gear reel 312 and drives the threaded holes within the worm gear reel 312 to mate with the threads of the lifting rod 320, thereby achieving the up and down motion of the lifting rod 320. In this structure, the lifting rod 320 presses the motor stator using the pressure rod 321 at its top, ensuring the stator is firmly positioned. At the same time, the sliding pin structure on the rotation-limiting plate 330 slides in contact with the rotation-limiting groove 322, allowing the lifting rod 320 to maintain linear motion during lifting and lowering, preventing deflection and ensuring the accuracy of the press-fitting operation.
[0029] By manually operating the turntable 110 and the tooling control assembly 200 using the knob 111, the turntable 110 and tooling control assembly 200 can be deflected as a whole, making the entire tooling structure more flexible to operate. Furthermore, the first guide slots 211 and second guide slots 221 in the fixed guide plate 210 and the rotating guide plate 220 are designed to be arc-shaped and in opposite directions. This allows the movable sleeve 230 to drive the clamping rod assembly 300 in radial motion when the rotating guide plate 220 rotates, achieving radial clamping of the motor stator and further improving the stator clamping stability.
[0030] In this embodiment, in order to enhance the stability of the structure, the locking ear 120 is fixedly installed on the surface of the workbench 100, and cooperates with the rotating guide plate 220 through a spring pin, so that the rotating guide plate 220 can be automatically locked when rotating, avoiding displacement of the equipment during vibration, thereby improving the safety of operation and the service life of the equipment. Example 2
[0031] In another embodiment, the utility model further optimizes the structure of the clamping rod group 300 to improve the efficiency and accuracy of the motor stator assembly. In this embodiment, the clamping rod group 300 also includes a drive box 310, a lifting rod 320 and a rotation limiter 330. Among them, the worm motor 311 on the drive box 310 realizes the rotation control of the worm gear wire reel 312 through the motor control method, so that the lifting rod 320 can be lifted and lowered more accurately. Through the improvement of this structure, different lifting speeds and displacement ranges can be set at the control end to adapt to motor stators of different specifications.
[0032] The structure of the lifting rod 320 and the movable sleeve 230 of this embodiment maintains the same clamping function as in the first embodiment, and through the guidance of the arc-shaped guide grooves 211 and the second guide grooves 221, provides an automatic centering function for the motor stator during the radial movement of the movable sleeve 230, ensuring that the stator is always in the center position during the clamping and pressing process, thereby improving the installation accuracy.
[0033] In addition, this embodiment incorporates a detection module, such as a pressure sensor located at the top of the lifting rod 320. This sensor is used to monitor the pressure of the lifting rod 320 in real time during the press-fitting process and feed this data back to the control module. When the preset pressure value is reached, the system automatically stops driving the worm motor 311 to prevent overpressure damage to the motor stator. This improvement enhances the intelligence level of the equipment, further reduces the need for manual monitoring, and increases the degree of automation.
[0034] Summary of working principles
[0035] In these two embodiments, the working process of the motor stator assembly tool of the present invention is as follows:
[0036] Radial Positioning: The operator places the motor stator beneath the press rod 321 at the top of the lifting rod 320. Manually operating the knob 111 adjusts the angle of the turntable 110 and the tooling control assembly 200 to align the motor stator with the tooling structure. In the radial direction, the rotation of the fixed guide plate 210 and the rotating guide plate 220 drives the radial movement of the movable sleeve 230, clamping the motor stator to the center position.
[0037] Axial press-fitting: The worm motor 311 is activated to rotate the worm gear reel 312, thereby controlling the lifting and lowering motion of the lift rod 320, causing the press rod 321 to descend and contact the motor stator. During the press-fitting process, the sliding pin of the rotation-limiting plate 330 slides against the rotation-limiting groove 322, ensuring stable linear motion of the lift rod 320 and preventing deflection.
[0038] Locking operation: After the radial positioning is completed, the spring pin of the locking ear 120 cooperates with the ridges on the rotating guide plate 220, so that the rotating guide plate 220 is automatically locked during the rotation process, ensuring that the equipment will not loosen during vibration.
[0039] Intelligent monitoring (Example 2): During the press-fitting process, the pressure applied is monitored in real time by the pressure sensor at the top of the lifting rod 320. Once the preset value is reached, the system automatically stops the press-fitting to prevent excessive squeezing of the motor stator.
[0040] Through the above operations, the motor stator assembly tool of the utility model can realize efficient automatic positioning and press-fitting of the motor stator, ensure installation accuracy and improve work efficiency.
