Description

Technical Field

[0001] The utility model relates to the technical field of iron core positioning seats, in particular to an iron core positioning seat for a traction motor. Background Technique

[0002] A traction motor is a key component used to drive rail transit vehicles (such as subways, light rails, multiple units, electric locomotives, etc.). It converts electrical energy into mechanical energy to drive the train. A stator core is installed inside the traction motor. The stator core is laminated from silicon steel sheets and is used to provide a magnetic circuit. Positioning holes and fastening holes need to be opened on the end face of the stator core. The positioning holes are used for precise alignment and fixation of the stator core with the machine base or other components. The fastening holes are used to fix the fasteners of the iron core, such as bolts, nuts, etc.

[0003] When opening the holes, it is necessary to open a plurality of holes in a cylindrical array on the end face of the stator core. After one hole is opened, it is necessary to adjust the angle of the stator core of the iron core, and then open the hole again for the stator core of the iron core. After the iron core is fixed, it is not convenient to rotate the iron core. It is often necessary to cancel the clamping and fixing of the stator core and then rotate the iron core, which will cause a certain deviation in the rotation process of the iron core, thus affecting the accuracy of hole opening.

Detailed implementation manners

[0028] The following further describes the technical solutions of the present utility model in conjunction with the drawings and specific embodiments.

[0029] Embodiment

[0030] As Figures 1 - 5As shown in the figure, the positioning seat of the traction motor iron core proposed by the utility model includes a base 1, and further includes a support disk 2 rotatably installed on the base 1. A fixing mechanism for fixing the stator iron core is installed on the support disk 2. The fixing mechanism includes a plurality of chutes 3 provided on the support disk 2. A fastening block 301 is slidably installed in the chute 3. A driving disk 302 is rotatably installed on the support disk 2. A plurality of connecting rods 303 are rotatably installed on the driving disk 302. The connecting rods 303 correspond to the fastening blocks 301 one by one and are rotatably connected. A first motor 304 is fixedly installed in the support disk 2. The output shaft of the first motor 304 is fixedly connected to the driving disk 302 coaxially. When fixing the iron core, first place the iron core on the support disk 2, and then start the first motor 304 to drive the driving disk 302 to rotate. The rotating driving disk 302 will drive the plurality of connecting rods 303 to rotate. The rotating connecting rods 303 will push the fastening blocks 301 to slide along the chutes 3, so that the plurality of fastening blocks 301 can be gathered together, and then the fastening blocks 301 will contact the iron core, and the iron core is fixed by the friction force between the fastening blocks 301 and the iron core.

[0031] Furthermore, a locking assembly is installed in the support disk 2 to fix the positions of the plurality of fastening blocks 301. After the plurality of fastening blocks 301 contact the iron core, in order to prevent the fastening blocks 301 from moving during the drilling process, the fastening blocks 301 can be fixed to improve the stability and accuracy of drilling. The locking assembly includes a sliding sleeve 305 fixedly installed in one of the chutes 3. A connecting rod 306 is slidably installed in the sliding sleeve 305. The connecting rod 306 is fixedly connected to the fastening block 301. A connecting pipe 307 is fixedly installed on the sliding sleeve 305. An electric control valve 308 is fixedly installed on the connecting pipe 307. An oil tank 309 is fixedly installed in the support disk 2. A pressing plate 310 is slidably installed in the oil tank 309. A first spring 311 is fixedly installed in the oil tank 309. The other end of the first spring 311 is fixedly connected to the pressing plate 310. Hydraulic oil 312 is filled on one side of the oil tank 309 away from the first spring 311. When driving the fastening block 301 to move, open the electric control valve 308. At this time, the first spring 311 applies pressure to the pressing plate 310, and the hydraulic oil 312 can be pressed into the gap between the sliding sleeve 305 and the connecting rod 306 through the pressing plate 310. After the position of the fastening block 301 is adjusted, close the electric control valve 308. At this time, the hydraulic oil 312 located inside the sliding sleeve 305 cannot flow back into the oil tank 309. When the fastening block 301 moves away from the iron core, the hydraulic oil 312 needs to be squeezed, and the hydraulic oil 312 cannot flow back, so that the movement of the fastening block 301 can be effectively prevented, thereby ensuring the stability of the fixation of the iron core and ensuring the accuracy of drilling.

[0032] As Figures 6 - 9As shown in the figure, the present embodiment further includes an adjustment mechanism. The adjustment mechanism is installed on the base 1. The adjustment mechanism drives the support disk 2 to rotate. A positioning mechanism is installed on the adjustment mechanism. The positioning mechanism limits the position-adjusted support disk 2. The adjustment mechanism includes a second motor 4 fixedly installed on the base 1. A transmission belt 401 is installed inside the base 1. The output shaft of the second motor 4 is coaxially and fixedly connected to one of the pulleys in the transmission belt 401. The other pulley of the transmission belt 401 is coaxially and fixedly connected to the support disk 2. When adjusting the angle of the iron core, the second motor 4 drives the transmission belt 401 to rotate, which can drive the support disk 2 and the fixing mechanism to rotate, and then drive the iron core located on the support disk 2 and fixed by the fixing mechanism to rotate, so that the angle of the iron core can be accurately adjusted, ensuring the accuracy of punching the iron core.

[0033] Furthermore, the positioning mechanism includes a connecting plate 5 fixedly installed on the pulley to which the transmission belt 401 is fixedly connected to the support disk 2. Limiting blocks 501 are fixedly installed at both ends of the connecting plate 5. A limiting groove 502 is fixedly installed inside the base 1. The limiting groove 502 is filled with hydraulic fluid. The limiting blocks 501 divide the hydraulic fluid into two parts. When the support disk 2 rotates, the two limiting blocks 501 of the synchronous belt will rotate. The rotating limiting blocks 501 will push the hydraulic fluid to move inside the limiting groove. Two end caps 503 are rotatably installed in the limiting groove 502. Both ends of the end cap 503 are fixedly connected to the two limiting blocks 501 respectively. Through the setting of the end cap 503, the top of the limiting groove 502 can be blocked, and the normal rotation of the limiting blocks 501 can be ensured. A push rod motor 504 is fixedly installed inside the base 1. A lifting plate 505 is slidably installed inside the base 1. The output shaft of the push rod motor 504 is fixedly connected to the lifting plate 505. A plurality of telescopic rods 506 and second springs 507 are fixedly installed on the lifting plate 505. The other ends of the telescopic rods 506 and the second springs 507 are fixedly installed with a blocking block 508. The blocking block 508 penetrates the bottom of the limiting groove 502 and extends into the limiting groove 502. When the angle adjustment of the support disk 2 is completed, the push rod motor 504 drives the lifting plate 505 to rise, and then drives a plurality of blocking blocks 508 to rise. When the rising path of the blocking block 508 is blocked by the limiting block 501, the second spring 507 will be compressed to prevent jamming. The blocking blocks 508 not blocked by the limiting block 501 will continue to rise and contact the end cap 503. At this time, if the support disk 2 continues to rotate, it needs to drive the limiting block 501 to rotate, and the limiting block 501 needs to push the hydraulic fluid to move. At this time, the hydraulic fluid is divided into multiple parts by a plurality of blocking blocks 508 and cannot communicate, so that the limiting block 501 cannot rotate at this time, and then the support disk 2 cannot rotate, ensuring the stability when punching the end cap of the iron core.

[0034] Among them, sealing rings 509 are fixedly installed on both sides of the limit block 501 and the end cover 503, and a sealing groove 510 for cooperating with the sealing ring 509 is provided in the limit groove 502. The setting of the sealing ring 509 can prevent the hydraulic fluid from leaking from the top of the limit groove 502, ensuring the sealing performance of the limit groove 502.

[0035] Working principle: When fixing the iron core, first place the iron core on the support plate 2, and then start the first motor 304 to drive the plurality of fastening blocks 301 to gather together. Then, the fastening blocks 301 come into contact with the iron core, and the iron core is fixed by the frictional force between the fastening blocks 301 and the iron core. When driving the fastening blocks 301 to move, open the electric control valve 308. At this time, the hydraulic oil 312 can enter the gap between the sliding sleeve 305 and the connecting rod 306. After the position of the fastening blocks 301 is adjusted, close the electric control valve 308. At this time, when the fastening blocks 301 move away from the iron core, the hydraulic oil 312 needs to be squeezed, and the hydraulic oil 312 cannot flow back, thus effectively preventing the fastening blocks 301 from moving, and further ensuring the stability of the iron core fixation and the accuracy of drilling.

[0036] When adjusting the angle of the iron core, drive the transmission belt 401 to rotate through the second motor 4, which can drive the support plate 2 and the fixing mechanism to rotate, and then drive the iron core located on the support plate 2 and fixed by the fixing mechanism to rotate, so that the angle of the iron core can be accurately adjusted, ensuring the accuracy of drilling the iron core. After the angle of the support plate 2 is adjusted, drive the plug block 508 to rise and contact the end cover 503 through the push rod motor 504. At this time, when the support plate 2 continues to rotate, it needs to drive the limit block 501 to rotate. However, when the limit block 501 wants to rotate, it needs to push the hydraulic fluid to move. At this time, the hydraulic fluid is separated into multiple parts by the plurality of plug blocks 508 and cannot communicate, so that the limit block 501 cannot rotate at this time, and further the support plate 2 cannot rotate, ensuring the stability when drilling the end cover of the iron core.
