Technical Field

[0001] The utility model belongs to the technical field of motor production, in particular to a motor winding clamping device. Background Art

[0002] The rotor is an important component of the motor. During the assembly process of the rotor, coils need to be wound to generate a magnetic field to make the motor rotate after power is turned on. When winding the coils around the rotor, a winding clamping device is required to fix the position of the rotor.

[0003] The existing motor winding clamping device usually clamps the rotor shaft and then winds the coil when clamping and fixing the rotor. During long-term use and observation, it is found that the existing motor winding clamping device usually has a fixed size of clamp when clamping and fixing the rotor shaft. When winding is required for rotors of different sizes, the current clamp size does not match, and the corresponding clamp needs to be replaced frequently, resulting in cumbersome operation.

[0004] To this end, the utility model provides a motor winding clamping device. Utility Model Content

[0008] Preferably, the side walls of the first fixing ring and the second fixing ring are both provided with a plurality of sliding holes; a spring rod is slidably connected in the sliding hole; in this step, by setting the spring rod to contact the side of the rotor shaft and generate a rebound force, the shaft can be clamped and fixed from the side; when the diameter of the shaft is different, the stretching distance of the spring rod will change accordingly, so as to improve the applicability of clamping and fixing.

[0009] Preferably, a magnet is fixedly connected to the end of the spring rod; the magnet is arranged in a circular shape; in this step, by arranging the magnet to connect the spring rod and adsorbing on the surface of the rotating shaft when the spring rod clamps and fixes the rotating shaft, the tightness of the connection between the spring rod and the rotating shaft can be improved, so as to reduce the situation where the rotating shaft slides and causes unstable position.

[0010] Preferably, the first fixing plate and the side wall of the second fixing plate are fixedly connected to a third fixing plate; a plurality of bristles are fixedly connected to the top of the third fixing plate; in this step, by setting the third fixing plate to connect the bristles, the surface of the rotor can be cleaned when the motor body drives the rotor to rotate, so as to reduce the situation where dust and particulate impurities adhered to the surface of the rotor cause uneven winding and affect the winding effect.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figures 1 to 3As shown, a motor winding clamping device described in an embodiment of the utility model comprises a base 1; a first fixing plate 11 is fixedly connected to the top of the base 1; a first electric push rod 13 is fixedly connected to the side wall of the first fixing plate 11; a motor body 14 is fixedly connected to the end of the first electric push rod 13; a first fixing ring 15 is fixedly connected to the output end of the motor body 14; a second fixing plate 12 is fixedly connected to the top of the base 1; a second electric push rod 16 is fixedly connected to the side wall of the second fixing plate 12; a second fixing ring 17 is rotatably connected to the end of the second electric push rod 16; when working, the rotor is placed in the center position of the base 1 and then the first electric push rod 13 is started to drive the motor body 14 and the first fixing ring 15 to move toward one end of the rotor shaft, and at the same time, the second electric push rod 16 is started to drive The second fixing ring 17 is driven to move toward the other end of the rotating shaft. When the first fixing ring 15 and the second fixing ring 17 are respectively in contact with the two ends of the rotating shaft, the rotor will be clamped and fixed from both ends of the rotating shaft. Then the motor body 14 is started to drive the first fixing ring 15 and the rotor and the second fixing ring 17 to rotate to perform the winding work. In this step, the first electric push rod 13 and the second electric push rod 16 are set to respectively drive the first fixing ring 15 and the second fixing ring 17 to clamp and fix from both ends of the rotating shaft of the rotor. When the first electric push rod 13 and the second electric push rod 16 respectively drive the first fixing ring 15 and the second fixing ring 17 to move different distances, rotors of different lengths can be clamped and fixed, thereby reducing the situation where the clamps do not match when replacing rotors of different lengths to improve applicability.

[0025] like Figure 3 As shown, the inner side walls of the first fixing ring 15 and the second fixing ring 17 are fixedly connected with a plurality of spring sheets 2; the spring sheets 2 are arranged in an arc shape; during operation, when the first fixing ring 15 and the second fixing ring 17 respectively cover the rotating shaft of the rotor from both ends, the surface of the rotating shaft will contact the spring sheets 2. At this time, the spring sheets 2 are pressed by the surface of the rotating shaft and will be deformed and generate a rebound force, thereby clamping and fixing the rotating shaft from the side of the rotating shaft. In this step, by arranging the spring sheets 2, when the first fixing ring 15 and the second fixing ring 17 cover the rotating shaft of the rotor, they can contact the side of the rotating shaft and generate a rebound force to clamp and fix it from the side, thereby reducing the shaking of the rotating shaft in the first fixing ring 15 and the second fixing ring 17 to improve the stability of the position of the rotor when it is clamped and fixed.

[0026] like Figure 3As shown, the side walls of the first fixing ring 15 and the second fixing ring 17 are both provided with a plurality of sliding holes 3; a spring rod 31 is slidably connected in the sliding hole 3; during operation, when fixing the rotor shafts of different diameters, the end of the spring rod 31 will contact the surface of the shaft, and the side of the shaft will press against the end of the spring rod 31 to stretch the spring rod 31, at which time the spring rod 31 will generate a rebound force to clamp and fix it from the side of the shaft. In this step, by setting the spring rod 31 to contact the side of the rotor shaft and generate a rebound force, the shaft can be clamped and fixed from the side. When the diameter of the shaft is different, the stretching distance of the spring rod 31 will change accordingly, so as to improve the applicability of clamping and fixing.

[0027] like Figure 3 As shown, a magnet 4 is fixedly connected to the end of the spring rod 31; the magnet 4 is arranged in a circular shape; during operation, when the spring rod 31 clamps and fixes the rotating shaft of the rotor, the magnet 4 will contact the surface of the rotating shaft and be adsorbed on the rotating shaft. In this step, by arranging the magnet 4 to connect the spring rod 31 and adsorb on the surface of the rotating shaft when the spring rod 31 clamps and fixes the rotating shaft, the tightness of the connection between the spring rod 31 and the rotating shaft can be improved, so as to reduce the situation where the rotating shaft slides and causes unstable position.

[0028] like Figure 1 As shown, the first fixing plate 11 and the second fixing plate 12 are fixedly connected to the side walls of the third fixing plate 5; a plurality of bristles 51 are fixedly connected to the top of the third fixing plate 5; during operation, when the motor body 14 drives the rotor to rotate, the bristles 51 come into contact with the surface of the rotor, and can clean the surface of the rotor when the rotor rotates, and sweep away some of the dust and impurities adhering to the surface of the rotor and the coil. In this step, by setting the third fixing plate 5 connected to the bristles 51, the surface of the rotor can be cleaned when the motor body 14 drives the rotor to rotate, so as to reduce the situation in which the dust and particulate impurities adhering to the surface of the rotor cause uneven winding and affect the winding effect.

[0029] like Figure 4 As shown, a collecting box 6 is fixedly connected to the top of the base 1; a drawer box 61 is placed in the collecting box 6; the drawer box 61 is slidably matched with the collecting box 6; during operation, part of the dust and particulate impurities swept away will fall into the drawer box 61 and be collected. When the collection is completed, the drawer box 61 can be taken out to pour out the impurities and dust therein, and then the drawer box 61 can be put back into the collecting box 6 to reset. In this step, the collecting box 6 and the drawer box 61 can be set to collect part of the dust and impurities swept away and reduce the scattering of dust and impurities. The drawer box 61 can be removable and put back to facilitate the removal of the collected impurities and dust, so as to improve the convenience of collecting dust and impurities.

[0030] like Figure 3As shown, the side walls of the two magnets 4 close to each other are fixed with elastic bands 7; during operation, when the magnet 4 is adsorbed on the surface of the rotor shaft, the elastic band 7 will wrap around the surface of the shaft to clamp the shaft. In this step, the elastic band 7 is arranged to connect the magnet 4 so that the shaft can be clamped when the magnet 4 is adsorbed on the surface of the shaft, so as to reduce the situation where the shaft slides when being clamped and fixed, resulting in unstable position.

[0031] Working principle: put the rotor in the center position of the base 1 and then start the first electric push rod 13 to drive the motor body 14 and the first fixing ring 15 to move toward one end of the rotor shaft, and at the same time start the second electric push rod 16 to drive the second fixing ring 17 to move toward the other end of the shaft. When the first fixing ring 15 and the second fixing ring 17 are in contact with the two ends of the shaft respectively, the rotor will be clamped and fixed from both ends of the shaft, and then the motor body 14 is started to drive the first fixing ring 15 and the rotor and the second fixing ring 17 to rotate to perform winding work. When the first fixing ring 15 and the second fixing ring 17 respectively cover the rotor shaft from both ends, the surface of the shaft will contact the spring sheet 2. At this time, the spring sheet 2 is supported by the surface of the shaft and will be deformed and generate rebound force, clamping and fixing the shaft from the side of the shaft. When the rotor shafts of different diameters are fixed, the spring sheet 2 will be deformed and generate rebound force. The end of the spring rod 31 will contact the surface of the shaft, and the side of the shaft will press against the end of the spring rod 31 to stretch the spring rod 31. At this time, the spring rod 31 will generate a rebound force to clamp and fix it from the side of the shaft. When the spring rod 31 clamps and fixes the rotor shaft, the magnet 4 will contact the surface of the shaft and be adsorbed on the shaft. When the motor body 14 drives the rotor to rotate, the bristles 51 will contact the surface of the rotor, and can clean the surface of the rotor when it rotates, and sweep away some of the dust and impurities adhering to the surface of the rotor and coil. Some of the dust and granular impurities swept away will fall into the drawer 61 and be collected. When the collection is completed, the drawer 61 can be taken out and the impurities and dust therein can be poured out, and then the drawer 61 can be put back into the collection box 6 to reset it. When the magnet 4 is adsorbed on the surface of the rotor shaft, the elastic band 7 will wrap around the surface of the shaft to clamp the shaft.
