[0029] As Figures 1 to 5As shown, the embodiment relates to a rotor commutator positioning and pressing equipment, comprising a rack 1. The rack 1 is provided with a positioning tool for positioning the rotor, and a pressing mechanism 3 for pressing the commutator on the rotor. The positioning tool comprises a positioning clamp 21 fixedly arranged on the rack 1, and a guide sleeve 22 arranged above the positioning clamp 21. The positioning clamp 21 is internally provided with a positioning groove 211 for loading or unloading the rotor from the side, and the guide sleeve 22 is provided with a guide channel 221 above the positioning groove 211. A plurality of guide ribs 222 for guiding the circumferential position of the commutator are arranged on the inner wall of the guide channel 221 of the guide sleeve 22. The pressing mechanism 3 can press the commutator from the guide channel 221 to the rotor in the positioning clamp 21. Among them, the design of the positioning clamp 21 ensures the accurate positioning of the rotor in the positioning groove 211, and the guide ribs 222 on the inner wall of the guide channel 221 of the guide sleeve 22 ensure the accurate circumferential position of the commutator during pressing. The pressing mechanism 3 presses the commutator on the rotor through the guide channel 221, ensuring the stability and accuracy of the pressing. Specifically, the positioning groove 211 of the positioning clamp 21 can load or unload the rotor from the side, which facilitates the installation and disassembly of the rotor. Therefore, the technical scheme of the present application solves the technical problems of inaccurate rotor positioning and unstable commutator pressing in the process of positioning and pressing the rotor commutator by precise positioning and guiding design. Compared with the prior art, the technical scheme of the present application has higher positioning accuracy and pressing stability, and can effectively improve the quality and efficiency of the positioning and pressing of the rotor commutator.

[0030] Further, the upper end of the guide ridge 222 is designed in a tapered shape with the end being narrow and the lower end being wide. The specific implementation of this design can include but is not limited to: the upper end of the guide ridge 222 can adopt a bevel transition, so that the width of the upper end gradually increases to the width of the lower end. Or, the upper end can adopt an arc transition, so that the commutator can enter the guide ridge 222 more smoothly during the guide-in process. In addition, the tapered shape of the guide ridge 222 can also be realized by different angles and curvatures to adapt to different models and sizes of commutators. Specifically, the tapered shape design of the guide ridge 222 makes the commutator enter the guide ridge 222 more smoothly during the guide-in process, reducing the possibility of jamming or deviation. Through this tapered shape, the commutator can gradually adapt to the width change of the guide ridge 222 when entering the guide ridge 222, thereby ensuring the stability and accuracy of the commutator during the guide-in process. This design not only improves the guide-in efficiency of the commutator, but also reduces the equipment downtime caused by poor guide-in, improving the overall production efficiency. Compared with the prior art, the technical scheme of the present application optimizes the shape of the upper end of the guide ridge 222, effectively solving the technical problem that the commutator is easily jammed or deviated during the guide-in process. In the prior art, the upper end of the guide ridge 222 is usually of fixed width, which causes the commutator to be easily jammed or deviated due to the sudden change in width when guiding in. The present application, through the design of the tapered shape, makes the commutator smoothly transition, avoiding the above problems, thereby improving the running stability of the equipment and the production efficiency.

[0031] As shown in Figure 2 and 4 , the inside of the positioning groove 211 is provided with a sensor assembly 23. When the rotor is not correctly installed in the positioning groove 211, the sensor assembly 23 triggers a stop signal. Thus, the technical scheme can effectively detect whether the rotor is correctly installed in the positioning groove 211 through the setting of the sensor assembly 23, and timely trigger a stop signal when not correctly installed, preventing incorrect operation. Compared with the prior art, this scheme not only improves the accuracy of rotor positioning, but also enhances the safety and reliability of the equipment, solving the technical problem of correctly installing the rotor in the positioning groove 211.

[0032] In specific solutions, the sensor assembly 23 comprises a top rod 231, an elastic component supporting the top rod 231, and a sensor 233 for detecting the displacement of the top rod 231. The front end of the top rod 231 is designed as an inclined block 234, which can extend into the positioning groove 211 and be supported in the inclined groove on the side of the rotor. Specifically, the top rod 231 of the sensor assembly 23 is supported by the elastic component, and can be displaced when the rotor is not correctly installed. The sensor 233 detects the displacement and triggers a stop signal. The inclined block 234 at the front end of the top rod 231 is designed to extend into the positioning groove 211 and contact the inclined groove on the side of the rotor, thereby ensuring the correct position of the rotor. For example, the elastic component can be a spring or other elastic material, and the sensor 233 can be a displacement sensor 233 or a pressure sensor 233 or other sensor 233 capable of detecting the displacement of the top rod 231, for accurately detecting the displacement of the top rod 231. The front end of the top rod 231 is designed as an inclined block 234, which can extend into the positioning groove 211 and be supported in the inclined groove on the side of the rotor. The elastic component can be a spring or other elastic material, for providing elastic support for the top rod 231. The sensor 233 can be a displacement sensor 233, a pressure sensor 233, or other sensor 233 capable of detecting the displacement of the top rod 231. As a preferred embodiment, the inclined block 234 of the top rod 231 can be designed to be adjustable in angle, to adapt to different models of rotors. The elastic component can be a spring with different hardness, to adjust the elastic support force of the top rod 231. The sensor 233 can be a high-precision displacement sensor 233, to improve the accuracy of detection. Thus, the technical solution of the present application realizes the detection of whether the rotor is correctly positioned, through the combination of the top rod 231, the elastic component, and the sensor 233. When the rotor is not correctly installed, the displacement of the top rod 231 changes, and the sensor 233 detects this change and triggers a stop signal. This design ensures the correct positioning of the rotor in the positioning groove 211, and avoids equipment failure or production quality problems caused by incorrect positioning of the rotor or incorrect model of the rotor. Compared with the prior art, the technical solution of the present application has higher detection accuracy and reliability, and can effectively improve production efficiency and product quality.

[0033] As Figure 3As shown, the rack 1 on the front side of the positioning groove 211 is also provided with a pressing mechanism 4, which includes a lifting cylinder 41 fixed on the rack 1, a pressing cylinder 42 provided on the output end of the lifting cylinder 41, and a pressing block 43 provided on the output end of the pressing cylinder 42. The output direction of the pressing cylinder 42 is towards the inlet and outlet direction of the positioning groove 211, and the pressing block 43 is designed as an arc-shaped block matched with the rotor side surface. Among them, the lifting cylinder 41 is used to control the vertical position of the pressing block 43, so that it can be adjusted according to the height of the rotor. The pressing cylinder 42 is used to control the horizontal position of the pressing block 43, so that it can be accurately pressed on the rotor side surface. The arc-shaped design of the pressing block 43 matches it with the rotor side surface, further enhancing the stability of the fixation. Specifically, the arc-shaped surface of the pressing block 43 can be completely matched with the rotor side surface, so as to uniformly distribute the pressure during the pressing process and avoid local stress concentration. As a preferred embodiment, the arc-shaped surface of the pressing block 43 can be further designed with elastic material such as rubber or silicone to increase the friction with the rotor side surface and further improve the firmness of the fixation. In addition, the output end of the pressing cylinder 42 can be equipped with a pressure sensor for real-time monitoring of the size of the pressing force, ensuring that the pressing force is within a safe range and avoiding damage to the rotor. Therefore, through the cooperation of the lifting cylinder 41 and the pressing cylinder 42, the pressing block 43 can be accurately pressed on the rotor side surface, ensuring the firm fixation of the rotor in the positioning groove 211. The arc-shaped design of the pressing block 43 matches it with the rotor side surface, further enhancing the stability of the fixation. This design effectively solves the defects of the open side positioning groove 211, and can position the rotor side surface through the pressing mechanism 4 when the commutator is pressed, improving the reliability and production efficiency of the equipment. Compared with the prior art, the technical scheme of the present application introduces the pressing mechanism 4 to solve the technical problem of the firm fixation of the rotor in the positioning groove 211. The open side design of the rotor is easy to cause displacement of the rotor during pressing, affecting the pressing quality. The introduction of the pressing mechanism 4 in the present application can accurately position and fix the rotor side surface during pressing, effectively avoiding the problem of rotor displacement and improving the precision and efficiency of pressing.

[0034] Further, the positioning clamp 21 is provided with a sleeve hole 212, and the guide sleeve 22 is detachably arranged in the sleeve hole 212. Through this design, the guide sleeve 22 can be conveniently installed and detached from the positioning clamp 21, facilitating maintenance and replacement, so that the corresponding guide sleeve 22 can be replaced according to the required processing type. The design of the sleeve hole 212 ensures the stability and accuracy of the guide sleeve 22, so that it can accurately guide the position of the commutator during the pressing process. This detachable structure not only improves the flexibility and maintainability of the equipment, but also reduces the equipment downtime and improves the production efficiency. Specifically, the design of the sleeve hole 212 can adopt various forms, such as circular, square or other geometric shapes, to adapt to different types of guide sleeves 22. The connection between the guide sleeve 22 and the sleeve hole 212 can adopt threaded connection, buckle connection or magnetic connection, etc., to ensure the stability and accuracy of the guide sleeve 22 during the pressing process. In addition, the material of the guide sleeve 22 can be selected from wear-resistant, corrosion-resistant metals or composite materials to prolong its service life. As a preferred embodiment, the disassembly of the guide sleeve 22 can be completed by manual operation or automatic equipment. For example, a handle or pull ring can be provided on the guide sleeve 22 to facilitate the disassembly and installation of the operator. Alternatively, an electric or pneumatic device can be provided on the positioning clamp 21 to automatically complete the disassembly and installation of the guide sleeve 22 by controlling the button or program. Therefore, the technical scheme of the present application solves the technical problem of inconvenient installation and disassembly of the guide sleeve 22 on the positioning clamp 21 through the design of the sleeve hole 212 and the detachable guide sleeve 22. Compared with the prior art, this design not only improves the flexibility and maintainability of the equipment, but also reduces the equipment downtime and improves the production efficiency. Specifically, the detachable design of the guide sleeve 22 makes maintenance and replacement more convenient, reducing equipment downtime. The design of the sleeve hole 212 ensures the stability and accuracy of the guide sleeve 22, improving the pressing quality. This technical scheme has significant advantages in practical application and can effectively improve the working efficiency and reliability of the rotor commutator positioning and pressing equipment.

[0035] As Figure 3As shown, the press-fitting mechanism 3 includes a longitudinal slide rail 31 arranged on the rack 1, a sliding seat 32 arranged on the longitudinal slide rail 31, a press rod 33 arranged on the sliding seat 32, and a press-fitting cylinder 34 driving the sliding seat 32 to move along the longitudinal slide rail 31. The longitudinal slide rail 31 is arranged to enable the sliding seat 32 to move along a fixed path, ensuring the stability of the moving track of the press rod 33. The sliding seat 32 can accurately control the pressing speed and force of the press rod 33 through the driving of the press-fitting cylinder 34, thereby realizing the accurate press-fitting of the commutator. The design of the press rod 33 can be adjusted according to actual needs, such as using press rods 33 of different shapes or materials to adapt to different models of commutators. The driving mode of the press-fitting cylinder 34 can be pneumatic, hydraulic or electric, and the specific selection depends on the actual application scenario and precision requirements of the equipment. The cooperation of the longitudinal slide rail 31 and the sliding seat 32 ensures the stability and accuracy of the press rod 33 during the press-fitting process. The driving of the press-fitting cylinder 34 makes the press-fitting process controllable, and the press-fitting force can be adjusted according to the size and material of the commutator, thereby effectively solving the problem of inaccurate position and direction of the commutator during press-fitting. Compared with the prior art, this scheme optimizes the mechanical structure, improves the accuracy and efficiency of press-fitting, reduces the rate of defective products caused by improper press-fitting, and has high practicality and innovation.

[0036] Further, the rack 1 is provided with a discharging track 5 on the side, and a discharging moving table 51 is movably arranged on the discharging track 5, and a discharging seat 52 for accommodating the rotor is arranged on the discharging moving table 51. The discharging track 5 can be designed as a straight track or a curved track, which is selected according to the layout requirements of the production line. The discharging moving table 51 can move on the track by motor driving or pneumatic driving to realize automatic discharging. The discharging seat 52 can be designed as an adjustable structure to adapt to different sizes of rotors. For example, the discharging seat 52 can be adjusted in height and width through slide rails or telescopic mechanisms. In addition, multiple accommodating positions can be arranged on the discharging seat 52, and each accommodating position can be independently adjusted to further improve the versatility of the equipment. By arranging the discharging track 5 and the discharging moving table 51, the present application realizes automatic discharging after the rotor is press-fitted. The discharging track 5 is fixed on the side of the rack 1, the discharging moving table 51 can move on the track, and the discharging seat 52 can accommodate the press-fitted rotor. This design enables the rotor to be quickly and orderly removed from the working area after press-fitting, improving production efficiency. The arrangement of the discharging moving table 51 also makes the discharging process more flexible, and the discharging position can be adjusted according to production needs. In addition, multiple accommodating positions can be arranged on the discharging seat 52 to adapt to different models of rotors, further improving the versatility and production efficiency of the equipment. Compared with the prior art, the discharging device of the present application has simple structure and convenient operation, and can effectively solve the problem of discharging after the rotor is press-fitted, and has high practicality and economy.

[0037] In a further aspect, a plurality of blanking seats 52 are constructed on the blanking moving platform 51 for accommodating different models of rotors. The design of the blanking seats 52 can be customized according to the shape and size of different models of rotors, ensuring that each blanking seat 52 can stably accommodate a specific model of rotor. Specifically, the blanking seats 52 can be adapted to different models of rotors through adjustable clamping devices or fixed-size grooves. For example, the blanking seats 52 can adopt a modular design, which can be adapted to different models of rotors by replacing clamping blocks of different sizes or adjusting the position of the clamping devices. As a preferred embodiment, the blanking seats 52 can also be equipped with sensors 233 for detecting whether the rotor is placed correctly and issuing an alarm or shutdown signal if the rotor is not placed correctly. Thus, the technical solution of the present application solves the problem that a single model of blanking seat 52 cannot adapt to multiple models of rotors in the prior art by providing a plurality of blanking seats 52 on the blanking moving platform 51. Specifically, each blanking seat 52 can be designed according to the needs of different models of rotors, ensuring that the rotor can be stably accommodated during the pressing process. This design not only improves the versatility of the equipment, but also reduces the time for equipment replacement or adjustment, thereby improving production efficiency. Compared with the prior art, the technical solution of the present application provides a plurality of blanking seats 52 adapted to different models of rotors, avoiding equipment downtime or adjustment due to changes in rotor models, and significantly improving the flexibility and production efficiency of the equipment.
