Description

Technical Field

[0001] The invention belongs to the technical field of DC motor rotor binding, and in particular relates to a DC motor rotor binding device and a binding method for the DC motor rotor binding device. Background Art

[0002] A DC motor is a rotating motor that can convert DC electrical energy into mechanical energy (DC motor) or mechanical energy into DC electrical energy (DC generator). It is a motor that can realize the mutual conversion between DC electrical energy and mechanical energy. When it operates as a motor, it is a DC motor that converts electrical energy into mechanical energy; when it operates as a generator, it is a DC generator that converts mechanical energy into electrical energy.

[0003] Since the DC motor rotor punching is an open slot (rectangular slot), the winding and insulation material embedded in the slot will be thrown out during high-speed rotation if they are not tied. Therefore, the DC motor rotor must be tied after the wire is embedded. When the core length is relatively short, only tie it at both ends. If the core length is relatively long (generally more than 120mm), it must be tied not only at both ends, but also in the middle.

[0004] When tying the rotor, there are requirements not only on the number of ties, but also on the tightness of the ties.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0042] Example 1

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 As shown, the DC motor rotor binding device includes a rotor fixing assembly, in which the rotor 50 is assembled and drives the rotor 50 to rotate;

[0044] A non-weft belt conveying assembly 20, wherein the conveying direction of the non-weft belt 40 in the non-weft belt conveying assembly 20 is arranged perpendicularly to the length direction of the rotor 50, and the non-weft belt conveying assembly 20 comprises a side plate 22, a positioning ring structure 23 and a plurality of rotating sleeve-structure members 24. In this embodiment, two rotating sleeve-structure members 24 are arranged on one side of the side plate 22, the positioning ring structure 23 is rotatably matched with the side plate 22, the non-weft belt 40 is assembled on the positioning ring structure 23, and the movable end of the non-weft belt 40 passes through the plurality of rotating sleeve-structure members 24 to bind the rotating rotor 50;

[0045] The rotating sleeve 1 structural member 24 comprises a shaft 241 assembled on the side plate 22, the shaft 241 is sleeved with the rotating sleeve 1 242, the friction plate 244, the spring fixing ring 245 and the pressure plate 247 in sequence, and then the hexagonal nut 26 is threadedly matched. The rotating sleeve 1 242 and the shaft 2 241 are rotationally matched through the deep groove ball bearing 1 243, a cylindrical helical compression spring 246 is arranged between the spring fixing ring 245 and the pressure plate 247, and a groove body for accommodating the end of the cylindrical helical compression spring 246 is opened on the spring fixing ring 245;

[0046] With the cooperation of the cylindrical helical compression spring 246 , the hexagonal nut 26 is rotated to push the pressure plate 247 to drive the spring fixing ring 245 and the friction plate 244 to move in the axial direction of the second shaft 241 , thereby changing the magnitude of the friction force between the friction plate 244 and the rotating sleeve 1 242 .

[0047] The tying method of the DC motor rotor tying device comprises the following steps:

[0048] S1. Adjustment of the rotating sleeve 1 structure 24: Rotate the hexagonal nut 26 on the shaft 241, and push the pressure plate 247 to drive the spring fixing ring 245 and the friction plate 244 to move in the axial direction of the shaft 241, and adjust the friction force between the friction plate 244 and the rotating sleeve 1 242 to a preset value; at the same time

[0049] Fixing the rotor 50: Fixing the rotor 50 on the rotor fixing assembly; at the same time

[0050] Preparation of the non-weft belt 40: Assemble the non-weft belt 40 on the positioning ring structure 23, and the movable end of the non-weft belt 40 passes through a plurality of rotating sleeves 242 in sequence;

[0051] S2. Rotor binding: The movable end of the non-weft belt 40 is bound to the rotor 50 , and the rotor fixing assembly drives the rotor 50 to rotate, driving the non-weft belt 40 to be released to complete the binding of the rotor 50 .

[0052] In the DC motor rotor binding device of the present technical solution, when the latitude belt 40 is released to bind the rotor 50, the latitude belt 40 drives the rotating sleeve 242 to rotate, and the rotating sleeve 242 is affected by the friction plate 244, the spring fixing ring 245, the pressure plate 247, and the cylindrical helical compression spring 246 during rotation and does not rotate "smoothly", thereby hindering the movement of the latitude belt 40; thereby achieving the purpose of controlling the tightness of the latitude belt 40 during the binding process of the rotor 50, and solving the problem in the prior art that the tightness of the latitude belt 40 cannot be controlled during the binding process of the DC motor rotor.

[0053] At the same time, in order to make the non-weft belt 40 have different degrees of tightness and be suitable for different binding requirements, a hexagonal nut 26 that can rotate on the second shaft 241 is provided in this embodiment. The setting of the hexagonal nut 26 has the function of locking the rotating sleeve one structure 24 on the one hand, and on the other hand, by rotating the hexagonal nut 26, the size of the friction between the friction plate 244 and the rotating sleeve one 242 can be adjusted, thereby controlling the "smoothness" of the rotating sleeve, so as to achieve the purpose of having different degrees of tightness of the non-weft belt 40. The specific adjustment method is as follows:

[0054] When the hexagonal nut 26 is rotated forward on the shaft 241, the push pressure plate 247 drives the spring fixing ring 245 and the friction plate 244 to move in the axial direction of the shaft 241 toward the rotating sleeve 1 242, thereby increasing the friction between the friction plate 244 and the rotating sleeve 1 242; when the hexagonal nut 26 is rotated reversely on the shaft 241, under the action of the cylindrical helical compression spring 246, the rotating sleeve 1 242, the friction plate 244, the spring fixing ring 245 and the pressure plate 247 are loosened as a whole and move away from the rotating sleeve 1 242, thereby reducing the friction between the friction plate 244 and the rotating sleeve 1 242.

[0055] To achieve stable assembly of the non-weft belt 40 and the freely rotatable arrangement of the positioning ring 232, as shown in FIG. Figure 3 , Figure 4 , Figure 5 As shown, the positioning ring structure 23 includes a shaft 231 that is rotatably matched with the side plate 22. Both ends of the shaft 231 are sleeved with positioning rings 232 and limiting rings 234, and then threaded with hexagonal nuts 26. The end of the positioning ring 232 away from the limiting ring 234 extends radially outward to form a limiting edge 233. The non-weft belt 40 is sleeved on the positioning ring 232 and is clamped and fixed by the limiting edge 233 and the limiting ring 234. At the same time, in order to achieve stable assembly of the positioning ring 232, as shown in FIG. Figure 5As shown, a convex ring 1 235 and a convex ring 236 are provided on the shaft 1 231 , and the ends of the two positioning rings 232 away from the limiting ring 234 are in contact with the convex ring 1 235 and the convex ring 236 respectively.

[0056] When assembling the positioning ring structure 23, assemble the left positioning ring 232 on the shaft 1 231, sleeve the left non-weft belt 40 on the left positioning ring 232, assemble the left limiting ring 234 on the shaft 1 231, and thread the left hexagonal nut 26 with the shaft 1 231 until the convex ring 1 235, the left positioning ring 232, the left limiting ring 234, and the left hexagonal nut 26 are tightly in contact; assemble the right positioning ring 232 on the shaft 1 231, and the right non-weft belt 40 It is sleeved on the right positioning ring 232, the right limiting ring 234 is assembled on the shaft 1 231, and the right hexagonal nut 26 is threadedly matched with the shaft 1 231 until the convex ring 236, the right positioning ring 232, the right limiting ring 234, and the right hexagonal nut 26 are tightly in contact; at this time, the non-weft belt 40 is sleeved on the positioning ring 232 and is clamped and fixed by the limiting edge 233 and the limiting ring 234, so as to realize the stable assembly of the positioning ring structure 23 and the freely rotatable setting of the positioning ring 232.

[0057] In this embodiment, both ends of the shaft 231 are sleeved with positioning rings 232 and limiting rings 234, so that both sides of the side plate 22 can be equipped with non-weft belts 40, and the widths of the non-weft belts 40 on both sides are 15 mm and 25 mm respectively. According to the binding requirements, non-weft belts 40 of different specifications are selected for binding. At the same time, both sides of the side plate 22 are matched with the rotating sleeve one structure 24 and the rotating sleeve two structure 25. The specific position distribution is as follows: Figure 3 , Figure 4 As shown, it can adapt to different binding requirements.

[0058] To solve the assembly problem of the second shaft 241 and the side plate 22, as Figure 6 As shown, a convex ring three 248 is provided on the second shaft 241. When assembling the second shaft 241, one end of the second shaft 241 is passed through the side plate 22 and then threaded with a hexagonal nut 26. The hexagonal nut 26 is rotated until the convex ring three 248 and the hexagonal nut 26 are in contact with the side plate 22, thereby fixing the relative position of the second shaft 241 and the side plate 22.

[0059] like Figure 3 , Figure 4 , Figure 7 As shown, the non-weft belt conveying assembly 20 also includes a plurality of rotating sleeve second structural members 25. In this embodiment, two are arranged on the left side of the side plate 22 and three are arranged on the right side of the side plate 22. The specific distribution positions are as follows: Figure 3 , Figure 4The rotating sleeve 2 structural member 25 comprises a shaft 3 251 assembled on the side plate 22, a rotating sleeve 252 is sleeved on the shaft 3 251, a deep groove bearing 253 is passed between the rotating sleeve 252 and the shaft 3 251, and a hole retaining ring 254 and a shaft elastic retaining ring 255 are arranged between the shaft 3 251 and the rotating sleeve 252.

[0060] like Figure 8 As shown, in the latitude belt conveying assembly 20, taking the right side of the side plate 22 as an example, the latitude belt 40 is sleeved on the positioning ring 232, and the movable end is sequentially passed through two rotating sleeves 1 242 and three rotating sleeves 252 to be tied with the rotor 50. During the tying process, the traveling latitude belt 40 drives the rotating sleeve 252, the rotating sleeve 1 242, and the positioning ring 232 to rotate. The setting of the rotating sleeve 2 structural member 25 supports the latitude belt 40, limits its travel path, and ensures the tension of the latitude belt 40 during the conveying process.

[0061] To solve the assembly problem of shaft three 251 and side plate 22, as Figure 7 As shown, a convex ring four 256 is provided on the shaft three 251. When the shaft three 251 is assembled, one end of the shaft three 251 passes through the side plate 22 and is threadedly matched with a hexagonal nut 26. The hexagonal nut 26 is rotated until the convex ring four 256 and the hexagonal nut 26 are in contact with the side plate 22, thereby fixing the relative position of the shaft three 251 and the side plate 22.

[0062] In order to realize the assembly of the rotor 50 in the rotor fixing assembly, the rotor fixing assembly can drive the rotor 50 to rotate, such as Figure 1 As shown, the rotor fixing assembly includes a machine tool 11, a spindle box 12 arranged on the machine tool 11, and a tailstock 13 arranged on the machine tool 11. The spindle of the driving member in the spindle box 12 passes through the spindle box 12 and is connected to a clamping plate 14. The tailstock 13 is rotatably matched with an internal thread sleeve 15, and a screw 16 is threadedly matched in the internal thread sleeve 15. The rotor 50 is clamped and fixed between the clamping plate 14 and the screw 16. The screw 16 is controlled to rotate in the forward direction, and the screw 16 moves in the direction of the clamping plate 14, and the distance between the screw 16 and the clamping plate 14 is shortened. The screw 16 is controlled to rotate in the reverse direction, and the screw 16 moves in the direction away from the clamping plate 14, and the distance between the screw 16 and the clamping plate 14 is increased.

[0063] When assembling the rotor 50, the rotor 50 is placed between the clamping plate 14 and the screw 16, and the distance between the clamping plate 14 and the screw 16 is controlled to be reduced until the clamping plate 14, the screw 16 and the two ends of the rotor 50 are in contact with each other, and the assembly of the rotor 50 is completed. When the rotor 50 is tied, the driving member in the main shaft box 12 drives the clamping plate 14, the rotor 50, the screw 16, and the internal threaded sleeve 15 to rotate synchronously.

[0064] like Figure 1As shown, the end of the screw 16 away from the clamping plate 14 is connected to a handle 17; the setting of the handle 17 improves the convenience of controlling the rotation of the screw 16. The rotation direction of the main shaft of the driving member is consistent with the rotation direction of the screw 16 when clamping the rotor 50; when the driving member drives the rotor 50 to rotate, the screw 16 and the clamping plate 14 are prevented from loosening the rotor 50.

[0065] In view of the fact that in the prior art, when the rotor core is relatively short, it is only tied at both ends. If the rotor core is relatively long (generally more than 120 mm), it is not only tied at both ends but also in the middle. The device is further optimized, and the specific settings are as follows: Figure 1 As shown, the DC motor rotor binding device also includes a position adjustment component, which adjusts the position of the non-weft belt conveying component 20 relative to the rotor 50 according to the binding position of the rotor 50.

[0066] The adjustment assembly 30 includes a drag plate 31, a drag plate handwheel 32 and a ball screw structure. The drag plate handwheel 32 is connected to the end of the screw in the ball screw structure, the other end of the screw is assembled with the machine tool 11, and the drag plate 31 is connected to the nut in the ball screw structure; the non-weft belt conveying assembly 20 also includes a base plate 21 vertically fixedly connected to the side plate 22, and the base plate 21 is connected to the drag plate 31.

[0067] The drag plate hand wheel 32 drives the lead screw to rotate, and the rolling of the ball in the nut pushes the nut to move linearly along the axial direction of the lead screw, driving the drag plate 31 to move back and forth in a straight line, that is, driving the non-weft belt conveying assembly 20 to move in the axial direction of the rotor 50, thereby meeting the binding operation of different positions of the rotor 50.

[0068] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
