Description

Technical Field

[0001] The utility model relates to the technical field of novel motor stators, in particular to a stator processing and positioning device. Background Art

[0002] The stator is the stationary part of the motor. The stator consists of three parts: the stator core, the stator winding and the frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate output current. The stator is an important component in the motor. In order to ensure the safety and wear performance of the motor during use, the precision of the stator processing is relatively high. In the prior art, when processing its periphery and end, a special clamp is generally used to clamp one end of the stator first to fix it, and then process the other end; then the stator is turned over, the other end is clamped, and the remaining end is processed. On the one hand, this method may damage the periphery of the stator. On the other hand, during the processing, the stator needs to be turned over and positioned twice, and the positions of the two positioning may not be completely consistent, which may lead to inconsistent processing at both ends of the stator, reduce the processing accuracy, and affect the safety and service life of the motor.

[0003] After searching, a stator processing positioning device is disclosed in the announcement number: CN206567893U, which includes a central sleeve, at least two supporting sliders and a push-pull power mechanism. The outer surface of the central sleeve is provided with at least two wedge-shaped grooves, and the bottom of the supporting slider is provided with a wedge-shaped ridge that fits into the wedge-shaped groove. The push-pull power mechanism is connected to the supporting slider and drives the supporting slider to slide along the wedge-shaped groove. When sliding toward the descending end of the wedge-shaped groove, the inner diameter of the supporting slider gradually decreases. At this time, the stator can be sleeved on the outer periphery of the supporting slider. When sliding toward the ascending end of the wedge-shaped groove, the outer diameter of the supporting slider increases, and the stator support can be fixed by radial tension. At this time, the outer circles of the two ends of the stator can be processed separately, which overcomes the defects of the existing stator processing technology that the stator needs to be flipped and positioned twice, which may lead to inconsistent processing at both ends of the stator and reduced processing accuracy.

[0004] This application cannot achieve precise positioning of the stator, which may easily cause the stator to shift in position during processing, resulting in deviations and easily leading to secondary positioning. In addition, the stator cannot be further processed after being firmly clamped, which increases labor intensity and reduces production efficiency. Therefore, it cannot meet usage requirements.

At this time, the output end of the second cylinder 29 in the clamping assembly 27 inside the frame 1 drives the swing rod 44 to swing, thereby driving the clamping arm 31 to clamp the stator 40 to be positioned. At the same time, the central push rod 33 in the middle of the clamping block 34 and the push rod head 32 slide upward or downward according to the size of the stator 40 after the clamping arm 31 clamps the stator 40, thereby stably clamping the stator 40, and then adjust the output ends of the third cylinder 37 in the positioning rings 19 at both ends of the protective tube 20 to push the fixing claws 39 on the outer wall of the push rod 38 to clamp the stator 40 in three directions, and then manually adjust the fixing bolts 42 inside the positioning ring 19 to complete the clamping in the last direction. Through this clamping method, the stator 40 can be clamped in both axial and radial directions to achieve precise positioning.

[0027] Specifically, after the stator 40 is clamped and fixed, the forward and reverse rotation of the motor 13 is adjusted according to the advancement or withdrawal of the stator 40, and the two motors 13 on the two connecting plates 14 are started. The gear 11 connected thereto is transmitted on the rack 16 through the transmission shaft 12. At the same time, the output end of the first cylinder 17 on the lower surface of the two enclosures 10 drives the connecting rod 18 to pull the stator 40 that has been firmly clamped in the protective tube 20, so that the stator 40 in the protective tube 20 is pushed to the equipment circle 6 for processing under the movement of the second slider 23 and the third slider 25 along the second slide groove 24. The copper wire wrapped around the equipment circle 6 is squeezed into the stator 40 by the expansion and contraction of the first hydraulic cylinder 5, so that the processing of the stator 40 is completed. During the contraction of the first hydraulic cylinder 5, the push plate 7 slides out from the left end of the frame 1, so that the stator 40 nested outside the equipment circle 6 is pushed out of the equipment circle 6, thereby completing the unloading work.

At this time, the output end of the second cylinder 29 in the clamping assembly 27 inside the frame 1 drives the swing rod 44 to swing, thereby driving the clamping arm 31 to clamp the stator 40 to be positioned. At the same time, the central push rod 33 in the middle of the clamping block 34 together with the push rod head 32 slides up or down according to the size of the stator 40 after the clamping arm 31 clamps the stator 40, thereby stably clamping the stator 40, and then adjusting the output end of the third cylinder 37 in the positioning rings 19 at both ends of the protective tube 20, so as to push the fixed claws 39 on the outer wall of the push rod 38 to clamp the stator 40 in three directions, and then manually adjusting the fixing bolts 42 inside the positioning ring 19 to complete the clamping in the last direction;

[0029] Secondly, after the stator 40 is clamped and fixed, the forward and reverse rotation of the motor 13 is adjusted according to the advancement or withdrawal of the stator 40, and the two motors 13 on the two connecting plates 14 are started. The gears 11 connected thereto are transmitted on the rack 16 through the transmission shaft 12. At the same time, the output ends of the first cylinders 17 on the lower surfaces of the two enclosures 10 drive the connecting rods 18 to pull the stator 40 that has been firmly clamped in the protective tube 20, so that the stator 40 in the protective tube 20 is moved along the second slide groove 24 along the second slide block 23 and the third slide block 25. The first hydraulic cylinder 5 is extended and retracted, thereby squeezing the copper wire wrapped around the equipment circle 6 into the stator 40 to complete the processing of the stator 40. During the contraction of the first hydraulic cylinder 5, the push plate 7 extends from the left end of the frame 1, thereby pushing the stator 40 nested outside the equipment circle 6 out of the equipment circle 6, thereby completing the unloading work. At the same time, during the contraction of the first hydraulic cylinder 5, the limit spring 3 set on the telescopic rod 46 on the limit plate 2 can effectively prevent the first hydraulic cylinder 5 from retreating too far.
