Description

Technical Field

[0001] The invention belongs to the technical field of motor rotor manufacturing, and in particular relates to a permanent magnet synchronous motor rotor manufacturing device. Background Art

[0002] A permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to generate a magnetic field. The permanent magnet synchronous motor consists of a stator, a rotor, an end cover, etc. The speed of its rotor is consistent with the current frequency of the stator winding. In this case, its rotor adopts a wound winding, which also includes the asynchronous starting method of the permanent magnet synchronous motor, that is, a squirrel cage winding is installed on the permanent magnet rotor.

[0003] The working principle of permanent magnet synchronous motor is based on the interaction between the rotating magnetic field generated by the stator and the magnetic field generated by the permanent magnets on the rotor. The rotor is equipped with pre-magnetized permanent magnets, which can generate a strong magnetic field when rotating, thereby providing greater output torque. The motor control system will accurately regulate the current to ensure that the motor rotor can rotate synchronously with the rotating magnetic field and maintain a stable operating state.

[0004] In the production and manufacturing of permanent magnet synchronous motor rotors, some workshops still use manual winding. Whether it is a wound-wire winding or a squirrel-cage winding, when the wire is manually embedded, slot paper is preferably inserted into the slots of the rotor core. The slot paper plays an insulating role. After the coil is wound in the slot paper, in order to ensure the subsequent installation between the rotor and the stator, it is necessary to ensure that the slot paper does not exceed the outer diameter of the core. At this time, the slot paper will be cut to the same size as the core in turn. In this case, the manual work is cumbersome and reduces the efficiency of rotor manufacturing. At the same time, the efficiency of cutting the slot paper often varies from person to person, which reduces the average production efficiency of the workshop. Summary of the invention

The rotation of the meshing gear 1 507 will drive the twisted shaft 401 to rotate, and the rotation of the meshing gear 2 508 will drive the rotating rod 301 to rotate.

[0059] Brief description of the use process: When using the permanent magnet synchronous motor rotor manufacturing device, the contact piece 203 is adjusted according to the outer diameter size of the core rotor. By rotating the knob 2010, the knob 2010 can be moved on the surface of the screw 209. When the knob 2010 cancels the contact with the surface of the outer ring 201, the angle of the screw 209 can be moved in the slide groove 2012. At this time, the rotation of the adjustment plate 202 is realized, and the slide groove 2012 and the slider 2011 cooperate with the adjustment plate 202 to guide the rotation. The movement of the adjustment plate 202 will drive the clamping groove 1 208 to move, and at this time, the clamping rod 207 and the contact piece 203 will be driven to move. The movement of the contact piece 203 will be guided by the sliding connection between the slider 1 205 and the slide groove 1 206. At the same time, the movement of the contact member 203 will drive the scraper 204 to cut the slot paper protruding from the core rotor, and the movement of the contact member 203 can be used to cut rotors of different outer diameters. In the initial state, the lower plate 103 will be located near the plate body 101. Then the operator will first take the core rotor that needs to cut the slot paper and insert one end of its shaft into the insertion rod 104. It should be noted that the rotor should be kept in the center of the insertion rod 104 as much as possible during the clamping. Then turn the knob 107 to realize the progressive movement of the screw 106 inside the threaded block 105. At this time, the screw 106 will drive the fixed block 109 and the abutment block 108 to move, and the abutment block 108 will abut and fix one end of the core rotor that needs to cut the slot paper. Then, the operation of the rotating motor 501 will drive the rod body 1 502 and the rotating gear 1 503 to rotate, wherein the rotating gear 1 503 will drive the two rotating gears 2 504 to rotate, and the rotating gear 2 504 will drive the rod body 2 505 to rotate, and the two rod bodies 2 505 will drive the two half gears 506 to rotate synchronously, wherein the two half gears 506 will intermittently drive the meshing gear 1 507 and the meshing gear 2 508 to rotate through their tooth design, and when the half gear 506 realizes one rotation, it will also drive the meshing gear 1 507 and the meshing gear 2 508 to rotate through the teeth. The rotation of the meshing gear 1 507 will drive the twisted shaft 401 to rotate, and the rotation of the meshing gear 2 508 will drive the rotating rod 301 to rotate. The rotation of the twisted shaft 401 will realize the lateral movement of the collar 402 through the clamping protrusion 403, and the collar 402 will synchronously drive the shift plate 103 to move, and the second guide rod 404 will guide the shift plate 103 to move through the guide hole 405. The shift plate 103 will drive the scraper 204 and cut the groove paper protruding from the surface of the iron core through movement. When the shift plate 103 moves from the side of the plate body 101 to the side of the plate body 2 102, the shift ring 302 can be mutually clamped through the clamping strip 303 and the clamping groove 2 304 to realize movement on the surface of the rotating rod 301.At the same time, under the action of the clamping strip 303 and the clamping groove 2 304, the synchronous rotation of the shifting ring 302 and the rotating rod 301 is realized, and the shifting ring 302 will drive the disc 305 to rotate synchronously when following the rotation of the rotating rod 301. At this time, the cross bar 307 will realize the movement trend around the disc 305 as the center of the circle, and in the changes of the disc 305 and the cross bar 307, the matching groove 3010 and the clamping cavity 309 respectively and intermittently match the clamping of the disc 305 and the cross bar 307, thereby realizing the transmission of the intermittent plate 308. At this time, when the disc 305 rotates one circle, the intermittent plate 308 rotates a quarter of a circle, and makes a rotation cycle of the contact piece 203 22.5 degrees. After the rotation adjustment, the octagonal cutting scraper 204 can cut the circular surface more closely. Then after the rotating rod 301 runs, the twisted shaft 401 drives the shifting plate 103 again to realize the moving cutting on the surface of the core rotor. This arrangement facilitates improving the production efficiency of the core rotor, distinguishes the inconvenience and tediousness of existing manual cutting, and can achieve the cutting of the slot paper on the surface of the core rotor in two movements and one rotation, bringing high efficiency to the production of the core rotor. At the same time, the device can be used in conjunction with core rotors of different outer diameters. When cutting different batches of workpieces, the contact piece 203 and the scraper 204 need to be adjusted in advance to fit the surface of the core rotor, ensuring the flexibility of the workshop. The cut slot paper is accumulated between the plate body 101 and the plate body 2 102.
