Description

Technical Field

[0001] This utility model relates to an auxiliary processing device for motor rotors used in ultra-high voltage / high power motors, specifically a device for assisting in the positioning and welding of rotors. Background Technology

[0002] The rotors used in ultra-high voltage / high-power motors are relatively large compared to micro motors. These motors are generally designed with structures such as a main shaft and wing plates. During the processing of the rotor, the wing plates need to be welded to the main shaft. Due to the large size of the rotor, the current processing method is to weld and fix each wing plate individually based on the experience of the welding workers, and then change the position to weld and fix the next wing plate. Because the position needs to be changed, the overall accuracy is difficult to control. Utility Model Content

[0003] The purpose of this utility model is to provide a rotor welding auxiliary positioning device, and the technical problem to be solved is: how to provide an auxiliary positioning device that can complete the welding and fixing of the wing plate without switching the position of the rotor.

[0004] A rotor welding auxiliary positioning device includes: The first clamping plate has a first shaft hole and a first wing hole inside, which respectively position and fix the main shaft and the longitudinal straight edge of the wing plate at one end of the rotor; The second clamping plate has a second shaft hole and a second wing hole inside, which respectively position and fix the main shaft and the inclined edge of the wing plate at the other end of the rotor. The length of the second wing hole is less than the length of the first wing hole. The first shaft hole, the first wing hole, the second shaft hole, and the second wing hole are all aligned in position. The first support column is fixed on a base plate to support the first clamping plate; The second support column is fixed to the aforementioned base plate to support the second clamping plate; The base plate has positioning holes for positioning and fixing the spindle head; The base column is fixed below the base plate to support it.

[0005] The first clamping plate is a plate-shaped structure, the first shaft hole is a round hole and is located in the middle, and the first wing hole is a square hole and extends laterally outward along the edge of the first shaft hole.

[0006] The second clamping plate is a plate-shaped structure. The second shaft hole is a round hole and is located in the middle. The shaft center of the second shaft hole is the same as the shaft center of the first shaft hole, and also keeps the shaft center of the main shaft in the same center. The second wing hole is a square hole and extends laterally outward along the edge of the second shaft hole. The second wing hole is aligned with the first wing hole.

[0007] The first support column is a lifting cylinder, which has multiple cylinders evenly arranged below the first clamping plate to drive the first clamping plate to rise and fall.

[0008] The second support column is a lifting cylinder, which has multiple cylinders evenly arranged below the second clamping plate to drive the second clamping plate to rise and fall.

[0009] The beneficial effects of this utility model are as follows: by designing the first clamping plate and the second clamping plate, the main shaft and the wing plate can be simultaneously limited and fixed in multiple directions without having to change the position and direction of the rotor; by designing the first support column and the second support column, the height of the two clamping plates can be adjusted to accommodate rotors of different height specifications; the first clamping plate fixes the longitudinal straight edge of the wing plate, and the second clamping plate fixes the oblique edge of the wing plate, thereby ensuring the accurate and firm fixation of each wing plate.

[0011] Please refer to Figures 1 to 5 The rotor welding auxiliary positioning device in the figure is mainly designed with a first clamping plate 1, a second clamping plate 3, a first support column 2, a second support column 4, a bottom column 6, and a bottom plate 5. In this case, the main shaft 7 and multiple wing plates 8 are positioned simultaneously by two clamping plates. In practical applications, the above components can be further optimized, such as by modifying, replacing or adding elements such as shape, structure, quantity and material.

[0012] The first clamping plate 1 in the figure is designed as a plate structure, which positions and fixes the upper middle part of the rotor, thus ensuring the vertical placement of the rotor. The first clamping plate 1 has a cavity forming a first shaft hole 11 and a first wing hole 12, which respectively positions and fixes the longitudinal straight edge of the main shaft 7 and the wing plate 8 at one end of the rotor. The shaft center of the first shaft hole 11 is ensured to be on the same axis as the shaft center of the rotor. The first shaft hole 11 is a circular hole that fits in close contact with the circular outer wall of the main shaft 7. The first wing hole 12 adopts a design of four square holes, which are evenly arranged and extend laterally along the edge of the first shaft hole 11, thus corresponding to the overall shape of the rotor and ensuring tight and precise assembly. In practical applications, the local design of the first clamping plate 1 can be optimized as needed, such as changing the number of first wing holes 12 according to different types of rotors.

[0013] The second clamping plate 3 in the figure is also designed as a plate structure, which positions and fixes the lower middle part of the rotor, thus ensuring the vertical placement of the rotor. The second clamping plate 3 has a cavity forming a second shaft hole 31 and a second wing hole 32, which respectively positions and fixes the main shaft 7 and the inclined edge of the wing plate 8 at the other end of the rotor. The inclined edge here can ensure the positioning of the wing plate 8 in both the horizontal and vertical directions. The shaft center of the second shaft hole 31 is ensured to be on the same axis as the shaft center of the rotor. The second shaft hole 31 is a circular hole that fits in close contact with the circular outer wall of the main shaft 7. The second wing hole 32 adopts a design of four square holes, which are evenly arranged and extend laterally along the edge of the second shaft hole 31, thus corresponding to the overall shape of the rotor and ensuring tight and precise assembly. In the figure, the second wing hole 32 is aligned with the first wing hole 12 and the length of the second wing hole 32 is less than the length of the first wing hole 12. In practical applications, the partial design of the second clamping plate 3 can be optimized as needed, such as changing the number of second wing holes 32 according to different types of rotors.

[0014] The first support column 2 in the figure has multiple fixed on the base plate 5 and below the first clamping plate 1 to support and fix the first clamping plate 1. The first support column 2 can be designed as a fixed type or a cylinder lifting type. If it is designed as a cylinder lifting type, it can drive the first clamping plate 1 to rise and fall.

[0015] The second support column 4 in the figure has multiple fixed on the base plate 5 and below the second clamping plate 3 to support and fix the second clamping plate 3. The second support column 4 can be designed as a fixed type or a cylinder lifting type. If it is designed as a cylinder lifting type, it can drive the second clamping plate 3 to rise and fall.

[0016] The base plate 5 in the figure is a conventional plate structure with a positioning hole 51 in the center, which is a cavity structure, so as to facilitate the positioning and fixing of the shaft head 71 at the bottom end of the rotor.

[0017] The base column 6 in the figure has multiple columns and is fixed below the base plate 5 to support the base plate 5. Its overall cylindrical design ensures sufficient support.
