Description

Technical Field

[0001] The invention relates to the field of motor winding devices, in particular to a rotary disc type three-phase asynchronous motor winding device. Background Art

[0002] The three-phase asynchronous motor is a type of motor that is powered by a 380V three-phase AC power supply. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. 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.

[0003] The existing large three-phase asynchronous motor stators are formed by winding copper wires around specific winding heads to form multiple bundles of rectangular coils. Figure 1 As shown, the winding head also needs to be used in conjunction with the mold. The mold includes a rotating base and multiple groups of needles arranged on the rotating base. A gap is left between two adjacent groups of needles for a bundle of coils to pass through. The winding head has multiple steps, and an avoidance groove 331 for accommodating the needles is opened in the vertical direction on the winding head.

[0004] In actual winding production, the mold remains stationary and the winding head moves down step by step, so that the corresponding group of needles enters the avoidance groove 331. As the number of winding turns increases, the coils wound on the corresponding steps will move down to be wound around the outside of the needles.

[0005] If the needle is completely inside the avoidance groove 331, the coil will not be directly wound around the needle, and the winding operation will proceed normally. If the needle is completely outside the avoidance groove 331, or most of it is outside the avoidance groove 331, the needle will not play a role in dividing the wire, and the operator can easily find the problem; Figure 2 As shown, if a small part of the needle is located outside the avoidance groove 331, the coil will act on the needle during winding. Since the coil is wound tightly, this part of the coil acting on the needle will force the top of the needle to bend, and the needle will further pull the copper wire. If the needle position deviation is not serious, these problems will not seriously affect the winding operation, and the operator will find it difficult to see during the winding operation. However, after a long time, the needle will remain in a bent state and it will be difficult to reset to a vertical state, which will affect the life of the needle. At the same time, the coil will be pulled, which will also affect the winding. Summary of the invention

[0009] Preferably, the auxiliary control assembly includes a second movable seat, a second driving member, two left pressure frames, two right pressure frames, two support blocks, a plurality of slide bars and a plurality of second springs, the plurality of slide bars are respectively fixedly arranged on the multi-stage movable steps of the left winding head, a plurality of slide bars are provided on a side wall of the first movable groove close to the right winding head, a plurality of slide bars are respectively slidably connected in the plurality of slide bars, a plurality of second springs are respectively located in the plurality of slide bars, two ends of the second springs are respectively abutted on the corresponding slide bar bottom wall and the corresponding slide bar, and the second springs always drive the slide bar to move toward the right winding head side; The second driving member is arranged on the frame, and is used for driving the second movable seat to move in the vertical direction.

Two support blocks are fixedly arranged at the bottom ends of the two left pressure frames respectively, and the support blocks are located in the first movable groove. Two chamfered surfaces are provided at one end of the support block facing the movable step, which are arranged in a tapered shape. The chamfered surfaces are used to abut the edges of the movable steps. When a certain step is performing a winding operation, the left side surface of the support block abuts against the corresponding step and the adjacent upper step at the same time, and the left pressure frame and the right pressure frame are both located above the corresponding step.

[0010] By adopting the above technical scheme, when the winding operation is carried out on the X-level step, the support block simultaneously supports the X-level step and the X+1-level step. At this time, the X-level step and the X+1-level step are both in the winding state, and the left pressure frame and the right pressure frame move to the top of the X-level step at the same time, which will not cause any impact on the winding operation. After the winding operation on the X-level step is completed, the second moving seat does not move, the first moving seat moves down, the support block will move up relative to the left winding head, and the support block will act on the X+1 and X+2-level steps. At this time, the X-level step is retracted, which is convenient for the coil on the X-level step to automatically detach from the X-level step, the X+1-level step remains in the winding state, which is convenient for the winding assembly to continue winding directly, and the X+2-level step is supported to the winding state under the action of the chamfered surface... It can realize automatic control of multiple steps to cooperate with the actual winding operation; after the winding operation is completed, the second moving seat moves down, and the left pressure frame and the right pressure frame can press down and detach all the coils that have not detached on all steps at one time.

[0011] Preferably, it also includes a driving member three, the rotating table includes a turntable body and a moving seat, the turntable body is rotatably set on the frame, a moving groove is opened on the turntable body, the moving seat is slidably connected in the moving groove along the radial direction of the turntable body, and the rotating base is rotatably set on the moving seat; the driving member three is used to drive the moving seat to move toward the side away from the axis of the turntable body when the needle body moves to reset under the action of the coil.

[0012] By adopting the above technical solution, when the needle body is moved down to the reset state under the action of the coil, it means that the position of the needle body deviates toward the side away from the right winding head, so by driving the moving seat to move toward the side away from the axis of the turntable body, the position deviation of the needle body can be corrected.

[0013] Preferably, the driving member three comprises a one-way bearing, a first gear, a rack, a connecting rod and an annular plate, the annular plate has side wings on both sides, the side wings are provided with guide rods, the guide rods are slidably connected to the turntable body in the vertical direction, a third spring is sleeved on the guide rod, and the two ends of the third spring are respectively abutted against the side wings and the turntable body; the annular plate is located between the moving seat and the lower seat, a plurality of ejector rods are provided at the bottom end of the needle body, a plurality of through grooves matching the plurality of ejector rods are opened on the lower seat, and the bottom ends of the plurality of ejector rods always extend to the bottom of the lower seat and are located directly above the annular plate; The rack is fixedly arranged on the side wall of the moving seat, the first gear is rotatably connected to the turntable body, the inner ring of the one-way bearing is coaxially fixedly connected to the first gear, the outer ring of the one-way bearing is provided with an inclined groove along the spiral direction, the one-way bearing is located directly below one of the side wings, the connecting rod is fixedly arranged directly below the corresponding side wing, the bottom end of the connecting rod protrudes toward one side of the one-way bearing, the protrusion is located in the inclined groove and moves along the inclined groove; When the needle body moves downward, the inner ring and the outer ring rotate synchronously, and the moving seat moves toward the side away from the axis of the turntable body; when the needle body moves upward, the inner ring and the outer ring rotate relatively, and the moving seat is in a stationary state.

[0014] By adopting the above technical scheme, when the needle body moves downward under the action of the coil, the needle body drives the push rod to move downward to push the annular plate downward, and the connecting rod on the side wing of the annular plate moves downward, and the protrusion on the connecting rod moves in the inclined groove to drive the outer ring of the one-way bearing to rotate. Since the inner ring and the outer ring are driven synchronously, the inner ring rotates while driving the first gear to rotate. The first gear finally drives the moving seat to move through the engagement with the rack, thereby fine-tuning the position of the mold body so that the needle body is completely located in the accommodating groove, reducing the impact on the winding operation; when the step is retracted, or after the fine-tuning of the needle body is completed due to the movement of the moving seat, the needle body moves up and resets. At this time, the annular plate moves up, and the protrusion on the connecting rod moves in the inclined groove to drive the outer ring of the one-way bearing to rotate. Since the inner ring and the outer ring are driven relative to each other, the rotation of the outer ring will not drive the rotation of the inner ring, so the first gear remains stationary.

The first clamp block is located between the second clamp block and the fixed block. The cutter is arranged on the second clamp block, and the first clamp block has a shearing notch that cooperates with the cutter.

[0020] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention reduces the influence of needle position deviation on the needle itself and the coil by giving way to the needle body during the winding process and giving way to the corresponding step of the left winding head after the winding is completed; 2. In the present invention, when the needle body is moved down to the reset process by the coil, it means that the position of the needle body deviates away from the right winding head, so by driving the moving seat to move away from the axis of the turntable body, the position deviation of the needle body can be corrected; 3.

[0048] Reference Figure 6-Figure 9 When the needle body 523 moves downward, the inner ring and the outer ring rotate synchronously, and the movable seat 512 moves toward the side away from the axis of the turntable body 511; when the needle body 523 moves upward, the inner ring and the outer ring rotate relative to each other, and the movable seat 512 is in a stationary state.

[0049] Reference Figure 6-Figure 9 When the needle body 523 moves downward under the action of the coil, the needle body 523 drives the push rod 66 to move downward to push the annular plate 65 downward, and the connecting rod 64 on the side wing 651 of the annular plate 65 moves downward. The protrusion 681 on the connecting rod 64 moves in the inclined groove 611 to drive the outer ring of the one-way bearing 61 to rotate. Since the inner ring and the outer ring are driven synchronously, the inner ring rotates while driving the first gear 62 to rotate. The first gear 62 finally drives the moving seat 512 to move through the meshing with the rack 63, thereby the mold body 5 2 is finely adjusted so that the needle body 523 is completely located in the accommodating groove to reduce the impact on the winding operation; when the step is retracted, or the needle body 523 is finely adjusted due to the movement of the movable seat 512, the needle body 523 moves up and resets. At this time, the annular plate 65 moves up, and the protrusion 681 on the connecting rod 64 moves in the inclined groove 611 to drive the outer ring of the one-way bearing 61 to rotate. Since the inner ring and the outer ring are driven relative to each other, the rotation of the outer ring will not drive the rotation of the inner ring, so the first gear 62 remains stationary.

The pressing block 71 is used to press against the moving seat 512. When the position of the moving seat 512 is automatically adjusted, the position of the moving seat 512 is locked by pressing against the moving seat 512 by the pressing block 71, which can prevent the moving seat 512 from deviating from the position under the action of external force and improve the stability of the moving seat 512.
