[0002] In the field of motor manufacturing, the stator, as a key component of the motor, plays a decisive role in the overall performance of the motor due to the precision and stability of its installation. During the motor stator installation process, the stator needs to be precisely installed into the motor housing and other components to ensure that the relative position of the stator with other components is accurate. This directly affects the magnetic field distribution, electromagnetic induction effect, and key performance indicators of the motor such as efficiency and torque output during operation.

[0003] Currently, traditional methods for installing and positioning motor stators have many drawbacks. On the one hand, some positioning fixtures have relatively simple designs and poor versatility, making them difficult to adapt to the pressing requirements of motor stators of different specifications and sizes. When faced with diverse product orders, companies often need to frequently change different types of positioning fixtures. This not only significantly increases production and time costs but also seriously affects production efficiency, restricting the company's flexibility and responsiveness to market changes. For example, in some small motor manufacturing companies, pressing different models of motor stators requires manual replacement of multiple specially designed positioning fixtures, with each fixture change potentially taking tens of minutes, greatly slowing down the production pace.

[0026] By adopting the above technical solution, the positioning gripper 35 in the positioning fixture 3, through the cooperation of the limiting slide groove 36, the slide rail 37, the spring 38 and the positioning block 39, can elastically clamp and finely adjust the positioning of the motor housing 26, ensuring that the motor stator 25 and the motor housing 26 are accurately positioned during press-fitting, improving the press-fitting accuracy, ensuring the assembly quality of the motor, and having high adaptability.

[0027] In this embodiment, an electrical cabinet box 12 and a control console 13 are respectively provided on the outer side of the press machine frame 11. A lower lifting device 14 is installed on the inner side of the lower end of the press machine frame 11, and the upper end of the lower lifting device 14 is fixedly connected to the three-jaw chuck 15. The three-jaw chuck 15 is provided with a worktable 16 at its upper end. The worktable 16 is fixedly installed on the frame body 11 of the press machine. The upper surface of the worktable 16 is provided with symmetrical guide rails 17. Buffers 18 are installed at both ends of the symmetrically arranged guide rails 17.

The motor housing 26 is located outside the motor stator 25, and the inner side of the motor stator 25 is connected to the three-jaw chuck 15. The upper inner side of the press machine frame 11 is connected to the upper lifting device 41. The bottom of the upper lifting device 41 is fixedly connected to the connecting plate 42. Multiple sets of sliding seats are symmetrically arranged on the lower surface of the connecting plate 42. The sliding seats are slidably connected to the slide rails symmetrically arranged on the upper surface of the press plate 44. A telescopic cylinder 43 is fixedly installed on one side of the connecting plate 42. The end of the telescopic cylinder 43 is fixedly connected to the pressing plate 44. The lower surface of the pressing plate 44 is symmetrically provided with pressing heads 45. The pressing heads 45 are correspondingly connected to the motor stator 25 and the motor housing 26.

[0028] By adopting the above technical solution The equipment automates a series of operations such as clamping, positioning and pressing of the motor stator 25 and the motor housing 26 through telescopic cylinder 1 24, telescopic cylinder 2 43 and lower lifting device 14, upper lifting device 41 and lifting device 31, reducing manual operation, improving production efficiency and reducing labor intensity. The sliding connection design between guide rail 17, guide rail 2, and other components, along with devices such as buffer 18, ensures the stability of the equipment during operation, reduces friction and collision between components, lowers the probability of equipment failure, and extends the service life of the equipment.

[0029] The working principle of this utility model is as follows: The operator first places the motor stator 25 and the motor housing 26 on the placement seat 23 on the upper surface of the slide table 21. The telescopic cylinder 24 is activated, and its piston rod extends to push the slide table 21 to slide smoothly along the guide rails 17 symmetrically arranged on the upper surface of the worktable 16. The slide blocks 22 symmetrically arranged on the lower surface of the slide table 21 are in close cooperation with the guide rails 17 to ensure the linearity and stability of the slide table 21. As the slide table 21 moves, the motor stator 25 and the motor housing 26 are transported to the predetermined pressing position. At this time, the lower lifting device 14 starts to work, and drives the motor stator 25 to make fine adjustments in height and angle through the three-jaw chuck 15 to ensure that the motor stator 25 is horizontal and the center position is accurate. During this process, the three-jaw chuck 15 uses the synchronous contraction and expansion of its three jaws to tightly hold the inner side of the motor stator 25 to achieve precise positioning. Subsequently, the lifting platform 33 descends vertically along the guide rails 19 symmetrically arranged on the outside of the press machine frame 11. When the lifting platform 33 descends to a suitable height, the double threaded seat 34 rotates under the drive of the motor. Due to the threaded connection between the two sides of the double threaded seat 34 and the positioning jaws 35, the positioning jaws 35 move synchronously towards the workpiece. In the multiple limiting grooves 36 arranged in a rectangular array on the positioning jaws 35, the slide rails 37 symmetrically arranged on the left and right and the springs 38 symmetrically arranged on the top and bottom cooperate with the positioning block 39. When the positioning jaws 35 approach the workpiece, the positioning block 39 first contacts the surface of the motor stator and the housing. As the positioning jaws 35 continue to move, the springs 38 are compressed, and the positioning block 39 slides along the slide rails 37 in the limiting grooves 36, finally achieving adaptive clamping and positioning of the motor stator 25 and the housing 26, ensuring that the workpiece will not be displaced during the press-fitting process. After the motor stator 25 and the motor housing 26 are clamped, the lifting device 41 is activated under the control of the control system, which drives the connecting plate 42 to descend vertically, and then drives the pressing plate 44 to descend. At this time, the telescopic cylinder 43 starts to work, and its piston rod extends and retracts to precisely adjust the position of the pressing plate 44, so that the pressing heads 45 symmetrically arranged on the lower surface of the pressing plate 44 accurately correspond to the pressing parts of the motor stator 25 and the motor housing 26. After confirming that the position is correct, the lifting device 41 continues to descend, driving the pressing plate 44 and the pressing heads 45 to move downward, and smoothly pressing the motor stator 25 into the motor housing 26 to complete the pressing work. After pressing is completed, the lifting device 41 drives the pressing plate 44 and the pressing head 45 to rise and reset; the lifting device 31 of the positioning fixture 3 drives the lifting platform 33 to rise, so that the positioning fixture 3 is separated from the workpiece; the telescopic cylinder 24 is started again, the piston rod retracts, and the slide 21 is pulled to move in the opposite direction along the guide rail 17, so that the pressed motor is transported to the unloading position, waiting for the operator to take it off or enter the subsequent automated production line process. The positioning gripper 35 in the positioning fixture 3, through the cooperation of the limiting slide groove 36, slide rail 37, spring 38 and positioning block 39, can elastically clamp and finely adjust the positioning of the motor housing 26, ensuring that the motor stator 25 and the motor housing 26 are accurately positioned during press-fitting, improving the press-fitting accuracy, ensuring the assembly quality of the motor, and also having high adaptability. The equipment automates a series of operations such as clamping, positioning and pressing of the motor stator 25 and the motor housing 26 through telescopic cylinder 1 24, telescopic cylinder 2 43 and lower lifting device 14, upper lifting device 41 and lifting device 31, reducing manual operation, improving production efficiency and reducing labor intensity. The sliding connection design between guide rail 17, guide rail 2, and other components, along with devices such as buffer 18, ensures the stability of the equipment during operation, reduces friction and collision between components, lowers the probability of equipment failure, and extends the service life of the equipment.
