Description

Technical Field

[0001] This utility model relates to the field of commutator assembly technology, and specifically to a commutator assembly device. Background Technology

[0002] In the field of motor manufacturing, the commutator, as a key component for converting electrical energy into mechanical energy, has a decisive impact on the overall performance of the motor due to the efficiency and quality of its assembly. While widely used rotary and linear distribution presses can achieve multi-station automated assembly, significant shortcomings remain in the commutator feeding process. Rotary presses typically use a ring-shaped turntable to sequentially transport the rotor to each station, while linear presses use a conveyor belt for linear workpiece transport. Both rely on vibratory feeders or manual feeding. However, vibratory feeders have limited storage capacity, requiring operators to frequently stop the machine to open safety devices and manually replenish the commutator in the hopper. Each replenishment session takes approximately 3-5 minutes, and replenishment is required 2-3 times per hour. This not only disrupts production line operations and reduces production efficiency (overall capacity decreases by approximately 15%-20%), but also increases labor costs and operational risks.

[0003] Based on this, the present invention designs a commutator assembly device to solve the above problems. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] In some embodiments, please refer to the accompanying drawings. Figures 1-9 A commutator assembly device includes a press 1, a worktable 2 fixedly mounted on the surface of the press 1, a rotor support platform 3 fixedly mounted on the top surface of the worktable 2, a rotor to be assembled mounted on the surface of the rotor support platform 3, a hydraulic cylinder 4 mounted on the top surface of the press 1, and a pressing assembly mounted on the telescopic end of the hydraulic cylinder 4. A symmetrical support frame 5 is fixedly connected to the outer surface of the press 1, a storage box 6 is fixedly mounted on the surface of the support frame 5, and equidistantly distributed feeding grooves 7 are formed on the surface of the pressing assembly. One side of the storage box 6... The storage tank 8 is provided with equidistantly distributed storage tanks 8, and the feeding tank 7 and storage tank 8 are connected. A baffle 9 is connected to the surface of the pressing component. The surface of the storage box 6 with storage tank 8 is always in contact with the baffle 9. A pushing component is installed on the inner wall of the storage tank 8. In use, the storage box 6 can store the commutator. With the connection between the feeding tank 7 and the storage tank 8, the pushing component pushes the commutator located in the storage tank 8 into the feeding tank 7. Then, the commutator is assembled with the rotor by the downward movement of the feeding tank 7. There is no need to stop the machine to replenish the commutator during the process.

[0029] In some embodiments, such as Figures 7-9As shown, in a preferred embodiment of this utility model, the storage tank 8 is shaped to penetrate the storage box 6 from the top. A limiting block 16 is inserted into the inner wall of the top opening of the storage tank 8, and the end of the storage tank 8 away from the baffle 9 is connected to an insertion port 14 opened on the surface of the storage box 6. The outer surface of the limiting block 16 is inserted and fitted into the inner wall of the insertion port 14. By setting the storage tank 8 to a structure that penetrates the storage box 6 from the top, inserting the limiting block 16 at the penetration point of the storage tank 8, and setting the insertion port 14 at the other end of the storage tank 8, the limiting block 16 can be inserted from the storage box 6. Pulling out the box 6 allows for rapid replenishment of the commutators stored inside the storage tank 8 without requiring a shutdown. The pushing component includes a first spring 10 fixedly connected to one end of the inner wall of the storage tank 8. Each first spring 10 on the inner wall of the storage tank 8 is rectangularly distributed. The other end of the first spring 10 is connected to a push plate 11. In use, one end opening of the storage tank 8 rests against the surface of the baffle 9, and then the commutators are placed equidistantly on the inner wall of the storage tank 8, creating a clamping space between the surface of the baffle 9 and the push plate 11. When the storage tank 8 is blocked... When plate 9 is blocked, the first spring 10 is in a compressed state. When the openings of the feeding trough 7 and the storage trough 8 are opposite each other, the commutator inside the storage trough 8 can be pushed into the feeding trough 7 by the cooperation of the push plate 11 and the first spring 10. The push plate 11 is arc-shaped to fit the existing commutator surface, which facilitates pushing. The inner wall of the storage trough 8 is provided with symmetrical guide grooves 13. The inner wall of the guide groove 13 is slidably connected with a protrusion 12. The end of the protrusion 12 is fixedly connected to the side wall of the push plate 11. This structure can limit the movement direction of the push plate 11. To prevent the push plate 11 from tilting due to the commutator's resistance during the elastic reset of the first spring 10, symmetrical baffles 15 are fixedly installed on the inner wall of the storage tank 8 near the top opening, and symmetrical strip grooves 17 are opened on the side wall of the limiting block 16. The baffles 15 and the strip grooves 17 are slidably connected. When the device is in use, the commutator being stored is located on the inner wall of the storage tank 8, and its top is located below the bottom surface of the limiting block 16. The baffles 15 and the strip grooves 17 can prevent the commutator from bulging upwards when pushed, thus affecting the storage state of the storage tank 8.

[0030] In some embodiments, such as Figures 1-6As shown, in a preferred embodiment of this utility model, the pressing assembly includes a pressing block 18 fixed to the telescopic end of the hydraulic cylinder 4. A feeding box 19 is fitted onto the outer surface of the pressing block 18. The bottom end of the baffle 9 is fixed to the top surface of the feeding box 19 near the storage tank 8. A pressing groove 20 adapted to the pressing block 18 is opened on the top surface of the feeding box 19. Top bolts 22 are fixedly connected to the bottom surface of the pressing block 18 at equal intervals. A top outlet 21 opposite to the top bolts 22 is opened on the bottom surface of the inner wall of the pressing groove 20. The feeding trough 7 is opened... On the side wall of the feed box 19, the end of the feeding trough 7 away from the storage trough 8 is inclined towards the bottom surface of the feed box 19 at an angle of 15°-30°. The end of the feeding trough 7 away from the storage trough 8 is connected to a discharge trough 701 that extends downward through the feed box 19. A support member connects the outer surface of the feed box 19 to the press 1. The support member includes a symmetrical carriage 29 fixedly connected to the side wall of the feed box 19. The press 1 has a U-shaped structure, and a corresponding opening is provided on the inner wall of the press 1 at the location of the carriage 29. The slide rail 26 and the slide frame 29, at the end away from the feed box 19, can slide on the inner wall of the slide rail 26. The top of the slide rail 26 is connected to an installation groove 27 opened inside the press 1. A symmetrical third spring 28 is fixedly connected between the top surface of the installation groove 27 and the slide frame 29. In addition, the baffle 9 is fixed on the side of the feed box 19 facing the storage box 6. When the hydraulic cylinder 4 extends its telescopic end downward, the feed box 19 and the pressure block 18 also move downward. The pressure block 18 moves downward on the inner wall of the pressure groove 20, allowing the top bolt 22 to insert. In the process of feeding the top outlet 21, when the feeding trough 7 and the storage trough 8 are connected, the commutator can be pushed into the inclined feeding trough 7 by the pushing component, and then slide from the feeding trough 7 into the discharge trough 701. As the top bolt 22 moves down, the commutator can pass through the discharge trough 701 and connect with the rotor on the surface of the rotor support platform 3. When the bottom surface of the pressure block 18 is completely in contact with the bottom surface of the pressure groove 20, the feed box 19 can move down, presenting a state in which the pressure block 18 and the feed box 19 can be completely moved down.

[0031] The bottom of the inner wall of the feeding trough 701 is provided with a circumferentially distributed notch 23. A second spring 24 is fixedly connected to one end of the inner wall of the notch 23. A ball bearing 25 is inserted into the opening of the notch 23. The surface of the ball bearing 25 is fixedly connected to the other end of the second spring 24. The ball bearing 25 is in a state where half of it is in the inner wall of the notch 23 and the other end is in the opening of the feeding trough 701. The circumferentially distributed ball bearing 25 can restrict the falling commutator to be assembled.

[0032] When using the commutator assembly equipment, open the top of the storage box 6, and put the commutators into the top through storage slot 8 in sequence. Insert the limit block 16 and fix it with the strip 15 and the strip slot 17 to prevent the commutator from moving upward. In the initial state, the hydraulic cylinder 4 is in the retracted state, and the feed box 19 is located at the top of the slide 26 under the action of the third spring 28. The opening of the storage slot 8 is located on the side wall of the feed box 19 near the bottom. The first spring 10 compresses the push plate 11.

[0033] When assembly is required, the hydraulic cylinder 4 is activated, which drives the pressure block 18 and the feeding box 19 to move down synchronously. When the feeding groove 7 is aligned with the storage groove 8, the first spring 10 pushes the push plate 11 to push the commutator into the inclined feeding groove 7, and then slides into the unloading groove 701 to be supported on the surface of the ball 25. As the pressure block 18 continues to move down, the top bolt 22 passes through the top outlet 21 and pushes the commutator out of the unloading groove 701, so that the ball 25 is put into the notch 23, and finally the press-fit is completed with the rotor on the rotor support table 3.

[0034] In the above technical solution, the elastic coefficient of the first spring 10 is 2-5 N / mm, and the elastic coefficient of the second spring 24 is 0.5-1 N / mm, ensuring that the ball 25 flexibly restricts the position of the commutator and does not hinder its fall. In addition, when the feed box 19 is subjected to a downward pressure resistance of 2 kg, the elastic coefficient of the third spring 28 is 3-8 N / mm, ensuring that the feed box 19 is stably reset. The total length of the baffle 9 and the feed box 19 covers the opening height of the storage tank 8.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
