Description

Technical Field

[0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to an insulating paper inserting machine for a motor stator. Background Art

[0002] The motor stator is the stationary part of the motor or generator used to generate a rotating magnetic field. It generates a rotating magnetic field through the periodic changes of the current in the stator winding, which in turn drives the rotor to rotate and realizes the conversion of electrical energy into mechanical energy; insulating paper is a general term for electrical insulating paper. It is used as an insulating material for various electrical equipment such as cables and coils. In addition to having good insulation properties and mechanical strength, it also has high toughness, excellent dielectric properties, high thermal conductivity, easy insertion, certain hardness and resilience. In order to ensure the safety and performance of the motor, it is necessary to insert insulating paper into the stator.

[0003] In a Chinese patent with publication number CN111478532B, a motor stator insulating paper inserting machine is mentioned. Its specification discloses that since the current stator is directly mounted on the material positioning mechanism, after the insulating paper is inserted, the insulating paper near one end of the material positioning mechanism is bound to remain on the through hole of the material positioning mechanism. Since the through hole structure needs to ensure that the insulating paper smoothly enters the slot body of the stator, it is the same as the slot body structure of the stator, so the friction between the through hole and the insulating paper is large. When the stator is pulled out, it is affected by the friction between the through hole and the insulating paper, causing the insulating paper to be easily displaced in the slot body of the stator. Therefore, after the stator is taken out, the insulating paper on the stator still needs to be shaped, resulting in low processing efficiency;

[0004] However, in the above applications, the mechanism that drives the stator to rotate is usually located inside the equipment, which makes subsequent inspection and maintenance particularly difficult. When the friction of the gear set increases after a long period of operation, it is often necessary to lubricate it to ensure the normal operation of the equipment and extend its service life. However, since these gear sets are located deep inside the equipment, it is difficult for operators to quickly access and handle these components during maintenance. This situation not only increases the complexity of maintenance work, but may also lead to prolonged downtime of the equipment, thereby affecting production efficiency and the overall reliability of the equipment. Therefore, in order to improve maintenance efficiency, it may be necessary to design a structure that is easier to inspect and lubricate. Summary of the invention

[0047] In this embodiment, the limiting cylinder 308 can realize precise limiting and guiding of the insulating paper tape released by the paper roller 103, and during the lubrication process, the adjustment of the limiting cylinder 308 can effectively collect the dripping lubricating liquid through cooperation with the second leakage hole 214, and the two arc-shaped slide rails 201 will not interfere with the long rod 303 and the slide rod 306 in the process of rotation of the support plate 1095, and the distance between the long rod 303 and one of the arc-shaped slide rails 201 is completely sufficient.

[0048] The inner walls of the two limiting cylinders 308 are both threadedly connected with cover plates 309 . The bottom surface of the rectangular plate 107 is provided with a second leakage hole 214 that matches the limiting cylinder 308 . The size of the inner wall of the limiting cylinder 308 is larger than that of the second leakage hole 214 .

[0049] In this embodiment, the cover plate 309 can be screwed off by means of thread drive when the limiting cylinder 308 collects the lubricating liquid.

[0050] The arc surface of the circular sleeve 304 is fixedly connected to the second L-shaped plate 311, and the surface of the second L-shaped plate 311 is slidably inserted with an insertion rod 312. The arc surface of the long rod 303 is provided with a plurality of insertion holes 313, and the plurality of insertion holes 313 are evenly arranged on the arc surface of the long rod 303. The size of the insertion rod 312 is adapted to the size of the insertion hole 313.

[0054] The working principle of the present invention is as follows: when in use, the stator body 1096 is placed on the support plate 1095, and the two slide blocks 202 slide inside the arc-shaped slide rail 201 to push the two cylinders 204 toward each other until the cylinders 204 contact the stator body 1096, and the cylinders 204 slide toward the stator body 1096 by sliding the cylinder 209 and the round rod 208, and the spring 211 contracts at this time, and the cylinders 204 are pushed toward the stator body 1096 by sliding the round tube 209 and the round rod 208. The block 210 is rotated to adjust the direction of the block 210 so that the block 210 faces the inner side of the limit plate 212. With the help of the resilience of the spring 211, the block 210 will eventually fit with the inner side of the limit plate 212, which plays a role in stabilizing the cylinder 204, thereby achieving the clamping and limiting of the stator body 1096. The screw 106 is driven by the first motor 105 to rotate, and the threaded rectangular plate 107 is moved to send the stator body 1096 to a suitable position below the paper insertion mechanism 101. , then release the insulating paper tape through the paper roller 103 and pass it between the two limiting cylinders 308, put the paper tape into the paper insertion mechanism 101, the paper insertion mechanism 101 and the transmission mechanism 109 will cooperate with each other, and after a paper tape is inserted into the slot in the stator body 1096, the second motor 1091 immediately drives the first gear 1092 to rotate, so that the second gear 1093 rotates, and then the stator body 1096 rotates, and stops immediately after turning to the next slot, and the paper tape is inserted into the slot in the stator body 1096 again, and this is repeated until all the slots in the stator body 1096 are filled. During the rotation of the stator body 1096, the two arc-shaped slide rails 201 will rotate with the rotation of the support plate 1095, and then the first motor 105 can be started again to make the output shaft of the first motor 105 rotate in the opposite direction, so that the rectangular plate 107 moves backward, that is, the stator body 1096 is away from the bottom of the paper insertion body, and the stator body 1096 is taken out;

[0055] When the first gear 1092 and the second gear 1093 need to be lubricated, one end of the guide tube 206 is inserted into the first leakage hole 213, and the limiting cylinder 308 is pulled toward the direction close to the long rod 303 by means of the sliding of the slide rod 306, and the limiting cylinder 308 is slid downward by means of the sliding of the round sleeve 304, and the direction of the limiting cylinder 308 is adjusted from a horizontal position to a vertical state by means of the rotation of the slide rod 306 and one of the first L-shaped plates 307, and then one of the limiting cylinders 308 is located below the second leakage hole 214 by pushing the slide rod 306, and the cover plate 309 can be screwed down by means of the thread, as shown in FIG. Figure 8 As shown, the piston rod 205 is then pushed to squeeze the lubricating liquid in the cylinder 204, and the lubricating liquid will flow out from the conduit 206 and drip between the first gear 1092 and the second gear 1093, and the excess lubricating liquid will drip into the limiting cylinder 308, wherein the sliding of the slide tube 302 can adjust the position of the limiting cylinder 308, so that the position of the limiting cylinder 308 and the second leakage hole 214 is more precise, and the driving rod 315 is turned, and the driving rod 315 is driven by the thread to contact the platform 1, so as to stabilize the position of the slide tube 302.
