For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Simultaneously, when an component is referred to as "fixed to" or "equipped on" another component, it can be directly on the other component or may have an intervening component present. When an component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present. When an component is referred to as "fixedly connected to" another component, it can be a common fixed connection method such as welding, bolting, or gluing. In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1, such as Figs. 1-3 As shown, a motor stator housing pressing device includes a support base 1, a stator mounting base 2 at the center of the upper part of the support base 1, support rods 3 around the upper perimeter of the support base 1, a support plate 4 connected to the top of the support rods 3, a pressing motor 5 connected to the support plate 4, the output end of the pressing motor 5 extending downward through the support plate 4 and connected to a lifting plate 6, and a lifting column 7 connected to the bottom of the lifting plate 6. A guide rod 21 is provided above the lifting plate 6, and the guide rod 21 is slidably connected to the support plate 4. The pressing motor 5 can drive the lifting plate 6 to rise and fall, thereby driving the lifting column 7 to rise and fall. The guide rod 21 serves as a guide for the rise and fall.

[0022] The bottom of the lifting column 7 is connected to an upper flange 8, on which an upper contact surface 9 is formed. The upper flange 8 is integrally formed from an upper disc body 23 and an upper ring body 24. The outer side of the upper ring body 24 forms the upper contact surface 9. The top of the motor housing 27 is fitted onto the upper contact surface 9, and the upper contact surface 9 is in contact with the upper inner side of the motor housing 27, achieving initial positioning of the motor housing 27. An annular magnet 22 is provided on the upper contact surface 9. The annular magnet 22 utilizes its unique magnetic field characteristics to generate an attractive force with the magnetic material in the motor housing 27. The attractive force of the annular magnet 22 makes it easier for the motor housing 27 to be installed and positioned with the upper flange 8. The worker only needs to bring the motor housing 27 close to the upper flange 8, and the motor will be attracted to the upper contact surface 9. No support is required, which saves effort and facilitates subsequent rotation and positioning, reducing the complexity and error rate of the operation.

[0023] Combination Figs. 2-3The two sides of the lifting column 7 are connected with clamping arms 10, the bottom side of the clamping arm 10 is connected with a clamping mechanism, the clamping mechanism is used for fixing the motor shell 27. The bottom of the clamping arm 10 is also connected with a limiting mechanism, the limiting mechanism comprises a telescopic rod 11, the front end of the telescopic rod 11 is connected with a positioning block 12, and the outside of the telescopic rod 11 is sleeved with a spring 13. One end of the spring 13 is connected with the end of the telescopic rod 11, and the other end of the spring 13 is connected with the positioning block 12. When the telescopic rod 11 is retracted, the spring 13 is also retracted.

[0024] A wire hole is arranged at the bottom of the motor shell 27, which is used for the cable in the motor to pass through. When the top of the motor is sleeved outside the upper ring body 24, the motor shell is rotated, and the telescopic rod 11 is retracted. When the motor shell 27 is rotated to the position that the wire hole at the bottom is aligned with the positioning block 12, the telescopic rod 11 is released, and the positioning block 12 extends to the wire hole under the elastic action until the positioning block 12 enters the wire hole. The wire hole at the bottom of the motor shell 27 is used as a positioning reference point. Through the cooperation of the telescopic rod 11 and the positioning block 12, when the motor shell 27 is rotated to the position that the wire hole is aligned with the positioning block 12, the positioning block 12 is automatically inserted into the wire hole under the action of the spring 13, so that the final position of the motor shell 27 is accurately checked and fixed.

[0025] In combination Fig. 2 The clamping mechanism comprises a clamping motor 14 and a clamping block 15. The clamping motor 14 is fixed to the bottom outer side of the clamping arm 10, the output end of the clamping motor 14 passes through the clamping arm 10 and is connected with the clamping block 15, and one end of the clamping block 15 is provided with an arc-shaped groove 16. When the top of the motor shell 27 is sleeved on the upper ring body 24 and the rotation positioning is completed, the two clamping arms 10 are driven by the clamping motors 14 at the bottom to move towards the motor shell 27, so that one end of the clamping block 15 with the arc-shaped groove 16 gradually approaches the motor shell 27, the motor shell 27 is clamped and fixed, and the fixing work of the motor shell 27 is completed. The clamping mechanism clamps and fixes the motor shell 27 by driving the clamping block 15 through the clamping motor 14, and the stability of the motor shell 27 in the pressing process is further enhanced. After the positioning and fixing work of the motor shell 27 are completed, the stator assembly 28 is placed on the stator mounting seat 2, the motor 5 drives the motor shell 27 to descend, and the motor shell 27 and the stator assembly 28 are pressed and assembled together

[0026] The upper flange part 8 is designed uniquely, and the upper fitting surface 9 formed thereon is tightly fitted with the upper inner side of the motor shell 27, which ensures the accuracy of the preliminary positioning of the motor shell 27 in the vertical direction. The contact between the outer upper fitting surface 9 of the upper ring body 24 and the inner side of the motor shell 27 provides a stable support point for the motor shell 27, which helps to prevent its deviation during the pressing process. In addition to the preliminary positioning of the upper flange part 8, the device is also equipped with a limiting mechanism, in which the positioning block 12 at the front end of the telescopic rod 11 can be accurately aligned and inserted into the threading hole at the bottom of the motor shell 27. This double positioning mechanism further ensures the positional accuracy of the motor shell 27 in the horizontal direction, and even if slight vibrations or external force disturbances occur during the pressing process, it can still maintain its stable position. The accurate positioning mechanism ensures the alignment accuracy of the motor shell 27 and the stator during the pressing process, thereby improving the pressing quality. This helps to reduce the problems of poor assembly, performance degradation, etc. caused by positional deviation, and improves the overall performance and reliability of the motor.

[0027] In combination Figs. 2-3 The stator mounting seat 2 includes a lower flange part 17 and a limiting rod 18. The lower flange part 17 is integrally formed by a corresponding lower disc body 25 and a lower ring body 26. The lower ring body 26 is located above the lower disc body 25. The limiting rod 18 is arranged at the inner side of the lower ring body 26. The limiting rod 18 and the inner side of the lower flange part 17 form a stator mounting space 19. The side edges of the lower flange part 17 are provided with upper and lower threading grooves 20. The bottom of the stator assembly 28 is mounted in the stator mounting space 19. The side of the stator assembly 28 with the cable is arranged towards the threading groove 20, so that the cable on the stator assembly 28 can directly extend out of the threading groove 20. After the motor shell 27 is fixed, the threading hole is arranged in alignment with the lower threading groove 20. The limiting rod 18 is arranged at the inner side of the lower flange part 17, and together with the inner side of the lower flange part 17 forms the stator mounting space 19. This design can accurately position and stably support the stator assembly 28, preventing it from shifting during the pressing process. The threading groove 20 is arranged in alignment with the threading hole at the bottom of the motor shell 27, so that after the motor shell 27 and the stator assembly 28 are pressed together, the cable can smoothly pass through the threading hole and the threading groove 20 without the need for additional adjustment and arrangement steps. This greatly simplifies the pressing process and improves work efficiency.
