[0034] The polishing assembly comprises a polishing assembly 8, the polishing assembly 8 is internally provided with a driving mechanism, the polishing assembly 8 further comprises a clamping mechanism 801, the clamping mechanism 801 is coaxial with the limit stop 4 and is driven to rotate by the driving mechanism, a lead screw 9 is arranged between the polishing assembly 8 and the limit stop 4, a movable moving mechanism 901 is arranged on the lead screw 9, and a detachable polishing block 902 is arranged on the moving mechanism 901 close to the axis of the clamping mechanism 801. The motor punching sheet iron core is first clamped by the clamping mechanism, the moving mechanism 901 is controlled to move by the lead screw 9, until the polishing block contacts the motor punching sheet iron core, and then the clamping mechanism is driven to rotate by the driving mechanism, while the motor punching sheet iron core is rotated and polished.

[0035] The position limiter 4 comprises an adjusting disc 401, which is hollow to facilitate the iron core to pass through, and four adjusting grooves 402 are formed on the outer edge of the adjusting disc 401, the adjusting grooves 402 are arc-shaped, the distance from each part of the arc-shaped groove to the adjusting disc 401 is different, the adjusting grooves 402 are annularly arranged around the central axis of the adjusting disc 401, and a movable rod 403 is arranged in the adjusting grooves 402 in a slidable manner, one end of the movable rod 403 close to the outer protective fence 1 is fixedly connected with an adjusting rod 404, the longitudinal adjusting rod 404 can only move vertically, the transverse adjusting rod 404 can only move horizontally, and one end of the adjusting rod 404 close to the center of the adjusting disc 401 is fixedly connected with an arc-shaped plate 405.

[0036] When the adjusting disc 401 rotates, the movable rod 403 moves in the adjusting grooves 402, but since the movement direction of the adjusting rod 404 is limited, the adjusting rod 404 can only move towards or away from the center of the adjusting disc 401, and the arc-shaped plate 405 is driven to move towards or away from the center of the adjusting disc 401, so that the hole size of the iron core entering the polishing assembly is adjusted, the size of the conveying hole is adjusted according to the cross-sectional radius of the iron core, and the stability of the iron core input into the polishing assembly is ensured.

[0037] The position limiter 4 further comprises a motor one 407, the motor one 407 is screw-mounted on the outer side of the outer protective fence 1, the output end of the motor one 407 is fixedly connected with a driving gear 408, the outer side of the adjusting disc 401 is provided with a clamping tooth, and the adjusting disc 401 is in meshing transmission with the driving gear 408.

When the lower arc-shaped plate 405 rises or falls, the lifting rod 406 is driven to rise or fall, and the conveying area 3 is driven to rise or fall as a whole, at this time, the central axis of the iron core still remains on the same straight line with the central axis of the adjusting disc 401, so that the iron core is input.

[0040] The advancing assembly 5 comprises a shell 501, the shell 501 is provided with a power adjusting assembly 7 at one end away from the outer protective fence 1, the output end of the power adjusting assembly 7 is connected with a threaded rod 503, the threaded rod 503 is located inside the shell 501, a advancing rod 504 is threaded on the outer side of the threaded rod 503, a sliding block 505 is fixedly arranged below one end of the advancing rod 504 close to the power adjusting assembly 7, a sliding groove 502 is fixedly arranged on the inner wall of the bottom of the shell 501, the sliding groove 502 is embedded with the sliding block 505, and the adsorbing assembly 6 is located at one end of the advancing rod 504 away from the power adjusting assembly 7. When the threaded rod 503 rotates, the advancing rod 504 will be driven to rotate, and since the sliding block 505 is embedded with the sliding groove 502, the advancing rod 504 cannot rotate, so that the threaded rod 503 rotates to drive the advancing rod 504 to move along the direction of the sliding groove 502.

[0041] The stopper 4 and the advancing rod 504 are located on the same central axis.

[0042] The power adjusting assembly 7 comprises a U-shaped plate 701, both ends of the U-shaped plate 701 are provided with connecting blocks 702, the middle part of the U-shaped plate 701 is connected with a motor two 703, the output end of the motor two 703 is fixedly connected with a horizontal bevel gear 704, the two connecting blocks 702 are rotatably provided with vertical bevel gears 705 close to each other, both the vertical bevel gears 705 are meshed with the horizontal bevel gear 704, when the horizontal bevel gear 704 rotates, the rotating directions of the two vertical bevel gears 705 are opposite, the connecting block 702 is connected with a rotating shaft 706 through a bearing, and the rotating shaft 706 is fixedly connected with the vertical bevel gear 705;

[0043] One end of the vertical bevel gear 705 close to each other is fixedly connected with a control column 707, the two control columns 707 are in contact with each other, one end of the threaded rod 503 close to the power adjusting assembly 7 is fixedly connected with a plug rod 508, the plug rod 508 penetrates through the vertical bevel gear 705 and inserts into the inside of the control column 707, one end of the plug rod 508 away from the threaded rod 503 is fixedly connected with a special-shaped block 509, the special-shaped block 509 is a rotationally symmetric figure in cross section, the rotation angle is very small, and the original figure can be coincided by rotating a very small angle, the inside of the control column 707 is provided with a special-shaped groove 708, the special-shaped grooves 708 in the two control columns 707 are communicated, and the special-shaped block 509 is embedded with the special-shaped groove 708;

[0044] When the conveying device is working normally, the power adjusting assembly 7 drives the pushing rod 504 to reciprocate according to the preset program, and the iron core is pushed to be processed. However, when the iron core does not pass through the adjusting disc 401 due to an unexpected situation and contacts the surrounding object, the pressure of the pushing rod 504 on the iron core will cause damage to the conveying device. When the pushing rod 504 is extruded, the plug rod 508 moves, driving the special-shaped block 509 to move into the special-shaped groove 708 inside another control column 707. At this time, the threaded rod 503 is reversed, and the pushing rod 504 is retracted, preventing the iron core from causing damage to the conveying device.

[0045] A limiting plate 506 is arranged at the connection between the threaded rod 503 and the plug rod 508. The outer side of the plug rod 508 is sleeved with a reset spring 507, and the two ends of the reset spring 507 are connected with the limiting plate 506 and the connecting block 702 close to the limiting plate 506.

[0046] The reset spring 507 can ensure that the device works normally after the iron core is taken out.

[0047] The adsorption assembly 6 includes an adsorber 601 fixedly connected with the pushing rod 504. The adsorber 601 is provided with a plurality of suction cups 602 at the end away from the pushing rod 504. The suction cups 602 are made of rubber and can be deformed. When the iron core does not move along the intended trajectory, the contact with the adsorption assembly 6 will not be parallel contact. An inner cavity 604 is formed in the inside of the adsorber 601, and the suction cups 602 are in communication with the inner cavity 604. An outer groove 606 is also formed in the inside of the adsorber 601 at the periphery of the inner cavity 604. A plurality of air outlets 607 are formed in the inside of the adsorber 601 perpendicular to the central axis direction of the inner cavity 604. The air outlets 607 are in communication with the outer groove 606 and the outside air through the inner cavity 604. The outer groove 606 is provided with a gas sealing ring 603 fitted therein. The damping between the gas sealing ring 603 and the outer groove 606 is large. The outer groove 606 is also provided with an adsorption spring 605, and the two ends of the adsorption spring 605 are connected with the gas sealing ring 603 and the inner wall of the outer groove 606, respectively.

[0048] When the iron core is extruded and deviated, the gas sealing ring 603 will move, thereby blocking the air outlets 607. At this time, the inside of the inner cavity 604 is sealed, and the suction cups 602 can suck the iron core after being extruded, thereby moving back together with the pushing rod 504 when the pushing rod 504 moves back.
