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 electrical machine that converts DC electrical energy into mechanical energy (a DC motor) or mechanical energy into DC electrical energy (a DC generator). It is a motor that can convert DC electrical energy into mechanical energy, and vice versa. When it operates as a motor, it is a DC motor, converting electrical energy into mechanical energy; when it operates as a generator, it is a DC generator, converting mechanical energy into electrical energy.

[0003] Since the DC motor rotor laminations are open slots (rectangular slots), the windings and insulation materials embedded in the slots will be thrown out during high-speed rotation if they are not tied. Therefore, the DC motor rotor must be tied after the wires are inserted. When the core length is relatively short, only the two ends are tied. 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 a rotor, not only the number of ties but also the tightness of the ties are required. Manual tying can only meet the required number of ties, but the tightness cannot be controlled. Therefore, a DC motor rotor tying device and a tying method for the DC motor rotor tying device are designed. Summary of the Invention

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions 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] The latitude belt conveying assembly 20 has a latitude belt 40 in which the conveying direction is perpendicular to the length direction of the rotor 50. The latitude belt conveying assembly 20 includes 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 provided on one side of the side plate 22. The positioning ring structure 23 rotates with the side plate 22. The latitude belt 40 is assembled on the positioning ring structure 23. The movable end of the latitude belt 40 passes through the plurality of rotating sleeve-structure members 24 to tie the rotating rotor 50.

[0045] The rotating sleeve 1 structure 24 includes a second shaft 241 assembled on the side plate 22. The second shaft 241 is sequentially sleeved with the rotating sleeve 1 242, the friction plate 244, the spring retaining ring 245 and the pressure plate 247, and then threadedly engaged with the hexagonal nut 26. The rotating sleeve 1 242 and the second shaft 241 are rotationally engaged via the deep groove ball bearing 1 243. A cylindrical helical compression spring 246 is disposed between the spring retaining ring 245 and the pressure plate 247. The spring retaining ring 245 is provided with a groove for accommodating the end of the cylindrical helical compression spring 246.

[0046] Under 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: Turn the hexagonal nut 26 on the second shaft 241 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, and adjust the friction between the friction plate 244 and the rotating sleeve 1 242 to a preset value; at the same time

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

[0050] Preparation of the flat belt 40: Assemble the flat belt 40 on the positioning ring structure 23, and pass the movable end of the flat belt 40 through the 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 . 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. During the rotation, the rotating sleeve 242 is acted upon by the friction plate 244, the spring fixing ring 245, the pressure plate 247, and the cylindrical helical compression spring 246, and does not rotate "smoothly", thereby hindering the movement of the latitude belt 40. Thus, the purpose of controlling the tightness of the latitude belt 40 during the binding process of the rotor 50 is achieved, and the problem of the inability to control the tightness of the latitude belt 40 during the binding process of the DC motor rotor in the prior art is solved.

[0053] At the same time, in order to make the non-woven belt 40 have different degrees of tightness and be suitable for different binding requirements, a hexagonal nut 26 that can be rotated 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 structure 24 on the one hand, and on the other hand, by rotating the hexagonal nut 26, the friction between the friction plate 244 and the rotating sleeve 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-woven belt 40. The specific adjustment method is as follows:

[0054] When the hexagonal nut 26 is rotated forward on the second 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 second 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 backward on the second 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] In order to achieve the stable assembly of the non-weft belt 40 and the setting that the positioning ring 232 can rotate freely, 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 latitude 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 respectively contact the convex ring 1 235 and the convex ring 236 .

[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, and the right limiting ring 234 is assembled on the shaft 1 231. 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 weftless belt 40 is sleeved on the positioning ring 232 and 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 free rotation setting of the positioning ring 232.

[0057] In this embodiment, both ends of the shaft 231 are provided with positioning rings 232 and limiting rings 234, so that both sides of the side panel 22 can be equipped with non-weft belts 40. The widths of the non-weft belts 40 on both sides are 15 mm and 25 mm respectively. According to the binding requirements, different specifications of non-weft belts 40 are selected for binding. At the same time, both sides of the side panel 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 conveyor assembly 20 also includes a plurality of rotating sleeve second structural members 25. In this embodiment, two are provided on the left side of the side plate 22 and three are provided on the right side of the side plate 22. The specific distribution positions are as follows: Figure 3 、 Figure 4The rotating sleeve 2 structure 25 includes a shaft 3 251 assembled on the side plate 22. The shaft 3 251 is sleeved with a rotating sleeve 252. A deep groove bearing 253 is provided between the rotating sleeve 252 and the shaft 3 251. A hole retaining ring 254 and a shaft elastic retaining ring 255 are provided between the shaft 3 251 and the rotating sleeve 252.

[0060] like Figure 8 As shown, in the lathe-belt conveyor assembly 20, taking the right side of the side panel 22 as an example, the lathe-belt 40 is enclosed in a positioning ring 232. The movable end is sequentially passed through two rotating sleeves 1 242 and three rotating sleeves 252 to be tied to the rotor 50. During the tying process, the advancing lathe-belt 40 drives the rotating sleeves 252, the rotating sleeves 1 242, and the positioning ring 232 to rotate. The provision of the rotating sleeve 2 structural member 25 supports the lathe-belt 40, defines its travel path, and ensures the tension of the lathe-belt 40 during conveyance.

[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 engaged 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 mounted on the machine tool 11, and a tailstock 13 mounted 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 engaged with an internally threaded sleeve 15, and a screw 16 is threadedly engaged with the internally threaded sleeve 15. The rotor 50 is clamped and fixed between the clamping plate 14 and the screw 16. When the screw 16 is controlled to rotate in the forward direction, the screw 16 moves toward the clamping plate 14, shortening the distance between the screw 16 and the clamping plate 14. When the screw 16 is controlled to rotate in the reverse direction, the screw 16 moves away from the clamping plate 14, increasing the distance between the screw 16 and the clamping plate 14.

[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 and the screw 16 contact the two ends of the rotor 50, thereby completing the assembly of the rotor 50. When the rotor 50 is tied, the driving member in the spindle 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, a handle 17 is connected to the end of the screw 16 away from the clamping plate 14. The provision of the handle 17 facilitates the control of 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. This prevents the screw 16 and the clamping plate 14 from loosening their grip on the rotor 50 when the driving member drives the rotor 50 to rotate.

[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 120mm), it is necessary to tie it not only at both ends but also in the middle. The present device is further optimized, and the specific settings are as follows: Figure 1 As shown, the DC motor rotor binding device further 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 weftless 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 handwheel 32 drives the screw to rotate, and the rolling of the ball in the nut pushes the nut to move linearly along the axial direction of the screw, driving the drag plate 31 to move back and forth in a straight line, that is, driving the weftless 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, rather than to limit the same.
