Description

Technical Field

[0001] This utility model relates to the field of motor rotor processing technology, specifically to a motor rotor processing tooling. Background Technology

[0002] Motor rotor machining fixtures are a series of tools and equipment used for machining motor rotors, designed to improve machining efficiency and quality. The design and composition of the fixtures vary depending on the specific application scenario. The motor rotor is the rotating part in the motor. The motor consists of two parts: the rotor and the stator. The quality of the motor rotor affects the performance of the motor.

[0003] After the initial assembly of existing motor rotors, metal burrs remain on the rotor surface, which can scratch the motor housing and increase the rotor's rotational resistance. Due to the special shape of the rotor, general grinding devices cannot effectively grind the grooves on the rotor. Therefore, a motor rotor machining fixture is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a tooling for machining motor rotors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A motor rotor machining fixture includes a first fixed plate, a first support plate fixedly connected to the top of the first fixed plate, a motor fixedly connected to one side of the first support plate, a first rotating shaft passing through the first support plate fixedly connected to the output end of the motor, a driving gear fixedly connected to the outer side of the first rotating shaft, a second rotating shaft rotatably connected inside the first support plate, a driven gear located outside the driving gear fixedly connected to the outer side of the second rotating shaft, a second support plate located to the right of the driving gear fixedly connected to the top of the first fixed plate, a grinding assembly provided on the outer side of the second rotating shaft, a first fixed tube fixedly connected to the side of the second support plate away from the first support plate, symmetrically arranged connecting holes opened on the right side of the first fixed plate, a connecting rod slidably connected inside the connecting holes, a first fixed hole opened on the outer side of the first fixed plate, a second fixed hole opened on the outer side of the connecting rod, a fixed rod slidably connected inside the first fixed hole and the second fixed hole, a second fixed plate fixedly connected to one end of the connecting rod, a third support plate fixedly connected to the top of the second fixed plate, a second fixed tube fixedly connected to one side of the third support plate, and a rotor provided inside the first fixed tube and the second fixed tube.

[0007] Preferably, a second pivot is connected through the interior of the second support plate, and a second pivot is provided on the inner side of the third support plate.

[0008] Preferably, the first fixing hole and the second fixing hole are a group, and there are several groups of the first fixing hole and the second fixing hole, which are evenly arranged inside the first fixing plate.

[0009] Preferably, the second rotating shaft and the grinding assembly are a set, and there are three sets of the second rotating shaft and the grinding assembly, which are evenly arranged on the surface of the rotor.

[0010] Preferably, the driving gear and the driven gear are meshed, and the diameter of the driving gear is larger than the diameter of the driven gear.

[0011] Preferably, the polishing assembly includes a spring telescopic rod fixedly connected to the outside of the second rotating shaft, and a polishing layer is fixedly connected to the end of the spring telescopic rod away from the second rotating shaft.

[0012] Preferably, the two ends of the polishing layer are arc-shaped, and the polishing layers are arranged in groups of four on the outside of the second rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, through the provided components such as a motor, a first rotating shaft, a driving gear, a driven gear, a second rotating shaft, a grinding assembly, a first fixing tube, and a second fixing tube, the fixing rod is first pulled out, then the connecting rod is completely pulled out of the connecting hole, separating the first fixing plate and the second fixing plate. Then, the notch on the outside of the rotor is aligned with the second rotating shaft. The rotor is then moved further until all three notches on the outside of the rotor are fitted onto the outside of the grinding assembly. The rotor is then pushed further until one end of the rotor is engaged in the first fixing tube. The connecting rod is then re-engaged into the connecting hole. The third support plate is then pushed further until the other end of the rotor is engaged in the second fixing tube. Once engaged, the nearest first fixing hole and second fixing hole are aligned. The rotor is then fixed by inserting the fixing rod into the first and second fixing holes. The output end of the motor drives the first shaft and the drive gear to rotate. The drive gear drives the driven gear to rotate. The driven gear drives the second shaft to rotate under the support of the first, second, and third support plates. The second shaft drives the grinding assembly to rotate. The grinding assembly grinds the grooves on the rotor surface, ensuring the smoothness of the grooves. This solves the problem that after the initial assembly of the existing motor rotor, metal burrs remain on the rotor surface, which scratch the motor housing and increase the rotor rotation resistance. Due to the special shape of the rotor, general grinding devices cannot effectively grind the grooves of the rotor.

[0015] 2. In this utility model, by setting components such as a first fixing hole, a connecting hole, a connecting rod, a second fixing hole, and a fixing rod, the proportion of the connecting rod entering the connecting hole can be adjusted by stretching, and the fixing rod can be combined with different first fixing holes and second fixing holes to achieve the effect of compatiblely fixing rotors of various lengths and sizes.

A first fixing tube 10 is fixedly connected to the side. A symmetrically arranged connecting hole 11 is opened on the right side of the first fixing plate 1. A connecting rod 13 is slidably connected inside the connecting hole 11. A first fixing hole 12 is opened on the outer side of the first fixing plate 1. A second fixing hole 14 is opened on the outer side of the connecting rod 13. A fixing rod 15 is slidably connected inside the first fixing hole 12 and the second fixing hole 14. A second fixing plate 16 is fixedly connected to one end of the connecting rod 13. A third support plate 17 is fixedly connected to the top of the second fixing plate 16. A second fixing tube 18 is fixedly connected to one side of the third support plate 17. A rotor 19 is provided inside the first fixing tube 10 and the second fixing tube 18.

[0027] The second support plate 8 has a second rotating shaft 6 connected through it. The second rotating shaft 6 is provided on the inner side of the third support plate 17. The first fixing hole 12 and the second fixing hole 14 are a group. There are several groups of the first fixing hole 12 and the second fixing hole 14, which are evenly arranged inside the first fixing plate 1. The second rotating shaft 6 and the grinding assembly 9 are a group. There are three groups of the second rotating shaft 6 and the grinding assembly 9, which are evenly arranged on the surface of the rotor 19. The driving gear 5 and the driven gear 7 are meshed and connected. The diameter of the driving gear 5 is larger than the diameter of the driven gear 7. The grinding assembly 9 includes a spring telescopic rod 91 fixedly connected to the outside of the second rotating shaft 6. A grinding layer 92 is fixedly connected to the end of the spring telescopic rod 91 away from the second rotating shaft 6. The two ends of the grinding layer 92 are arc-shaped. The grinding layers 92 are arranged in groups of four, evenly arranged on the outside of the second rotating shaft 6.

[0028] Workflow: When a motor rotor machining fixture is required, the entire device is powered externally. First, pull out the fixing rod 15, then pull out the connecting rod 13 completely from the connecting hole 11, separating the first fixing plate 1 and the second fixing plate 16. Then, align the notch on the outside of the rotor 19 with the second rotating shaft 6.

The grinding layer 92 fits into the grooves on the surface of the rotor 19 under the action of the spring telescopic rod 91. The grinding ensures the flatness of the grooves. Through the components such as the first fixing hole 12, the connecting hole 11, the connecting rod 13, the second fixing hole 14 and the fixing rod 15, the proportion of the connecting rod 13 entering the connecting hole 11 is adjusted by stretching. The combination of the fixing rod 15 with different first fixing holes 12 and second fixing holes 14 achieves the effect of compatiblely fixing rotors 19 of various lengths and sizes.
