Description

Technical Field

[0001] This utility model relates to the field of motor shaft manufacturing technology, specifically to a fault-prevention mechanism for heat treatment of motor shafts. Background Technology

[0002] Error prevention measures in the heat treatment of motor shafts are crucial in the production process. They can ensure product quality and consistency, reduce defect rates and production risks. In the heat treatment of motor shafts, the quenching process differs from that of many other components. When quenching motor shafts, only the outer surface is heated, and the core shaft itself is not heated.

[0003] The quenching characteristics of motor shafts mean that only the outer surface needs to be heated during the heating process. However, existing quenching methods require the motor shaft to be placed stably before heating. During this process, the outer surface of the motor shaft is prone to being contaminated with dust and other foreign matter. Once this dust and foreign matter form a thin film, it will affect the quenching efficiency of the corresponding position on the motor shaft, thereby affecting the strength of the motor shaft in the future.

[0004] Therefore, it is necessary to design a fault-prevention mechanism for heat treatment of motor shafts to solve the above problems. Utility Model Content

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] Obviously, many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Please see Figure 1-3This utility model provides a fault-prevention mechanism for heat treatment of motor shafts, including a processing table 1. A first servo motor 4 and a second servo motor 5 are fixedly connected to the top of the processing table 1. A second rotating chuck 24 is rotatably connected to the bottom of the inner cavity of the processing table 1. A first rotating shaft 6 is fixedly connected to the output shaft of the second servo motor 5. A first rotating chuck 7 is fixedly connected to the bottom end of the first rotating shaft 6. A first screw 3 is fixedly connected to the output shaft of the first servo motor 4. A first threaded sleeve 2 is threadedly sleeved onto the output shaft of the first screw 3. Two symmetrical connecting blocks 25 are fixedly connected to one side of the first threaded sleeve 2. A quenching ring 9 is fixedly connected to one side of one connecting block 25, and a cleaning ring 10 is fixedly connected to one side of the other connecting block 25. A positioning shaft 8 is slidably inserted between each of the connecting blocks 25. Another connecting block 25 is fixedly connected to one side of each of the cleaning ring 10 and the quenching ring 9. Another positioning shaft 8 is slidably inserted inside the two connecting blocks 25. A connecting plate 21 is fixedly connected to the two connecting blocks 25 on the side away from the processing table 1. A lifting mechanism is provided on the connecting plate 21. The lifting mechanism is connected to a second threaded sleeve 17. Two symmetrical third rotating shafts 16 are rotatably connected to one side of the second threaded sleeve 17. Four symmetrical support columns 11 are fixedly connected to both sides of the outer surface of the cleaning ring 10. A sliding sleeve 12 is slidably inserted into the bottom of the two support columns 11 on the same side. The cleaning ring 10 is equipped with two sliding blocks 13, each with cleaning bristles on one adjacent side. The outer surface of the cleaning ring 10 has two symmetrical insertion ports, and the two sliding blocks 13 are slidably disposed within the two insertion ports. Each of the two sliding blocks 13 is rotatably connected to a second rotating shaft 14 on one side, and the two second rotating shafts 14 are inserted into the outside of the connecting plate 21. The outer surface of the connecting plate 21 has two symmetrical square sliding openings, and the two second rotating shafts 14 are slidably inserted into the two square sliding openings. On the same side, the outer surface of one second rotating shaft 14 and one third rotating shaft 16 are rotatably fitted with a rotating block 15, for a total of two rotating blocks 15. The outer surface of the quenching ring 9 is provided with... The two line connection terminals 23 are connected to the outer surface of the cleaning ring 10, which is connected to two symmetrical water source connection pipes 22. Before use, by turning on the first servo motor 4 and raising the first threaded sleeve block 2, the quenching ring 9 and the cleaning ring 10 are placed at the top of the inner cavity of the processing table 1. The two water source connection pipes 22 are connected to the rinsing water source, and the two line connection terminals 23 are used to heat the quenching ring 9 so as to quench the motor shaft connecting the first rotating tip 7 and the second rotating tip 24. Before quenching, the quenching ring 9 and the cleaning ring 10 are lowered synchronously by lowering the first threaded sleeve block 2. When lowering, the second servo motor 5 is turned on, causing the motor shaft to rotate. At this time, the two sliding blocks 13 are inserted into the two plug interfaces.Multiple cleaning bristles are used to flush and clean the outer surface of the motor shaft. When the quenching ring 9 and cleaning ring 10 reach their lowest point, the lifting mechanism lowers the second threaded sleeve 17, causing the two sliding blocks 13 to slide out of the insertion interface. This allows the cleaning bristles to slide out of the quenching ring 9. At this time, the first threaded sleeve 2 opens and rises, allowing the quenching ring 9 to quench the rotating motor shaft. Two water supply pipes 22 cool the quenched surface, preventing the motor shaft core from being quenched simultaneously and avoiding quenching errors. This process improves the efficiency of motor shaft quenching.

[0020] It should be noted that the lifting mechanism described above includes a third servo motor 19. When the third servo motor 19 is turned on, the rotation of the second screw 18 causes the second threaded sleeve 17 inside the groove to rise and fall. This, in turn, drives the two rotating blocks 15 to rotate by the rotation of the two third rotating shafts 16, thereby pushing the two second rotating shafts 14 to slide at the two square sliding openings, thus adjusting the position of the two sliding blocks 13.

[0021] In order to facilitate the lifting and lowering of the first threaded sleeve 2 to drive the lifting and lowering of the quenching ring 9 and the cleaning ring 10, a sliding groove is provided on one side of the inner cavity of the processing table 1. The first threaded sleeve 2 is slidably disposed inside the sliding groove, and the two sides of the first threaded sleeve 2 are respectively attached to the two sides of the sliding groove.

[0022] To improve the stability of the lifting and lowering of the quenching ring 9 and the cleaning ring 10, the top and bottom of the two positioning shafts 8 are fixed to the top and bottom of the inner cavity of the processing table 1, respectively, and the two positioning shafts 8 are located on both sides of the first rotating chuck tip 7 and the second rotating chuck tip 24, respectively.

[0023] To facilitate the lifting and sliding of the quenching ring 9 and the cleaning ring 10, the motor shaft can be cleaned before quenching, thus avoiding errors during quenching. The orientation of the quenching ring 9 and the cleaning ring 10 prevents the core shaft from being quenched. The quenching ring 9 and the cleaning ring 10 are slidably positioned between the first rotating tip 7 and the second rotating tip 24. One end of each of the two water source connecting pipes 22 is flush with one side of the inner cavity of the cleaning ring 10, and one end of each water source connecting pipe 22 is connected to the inner side of the cleaning ring 10.

[0025] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
