Description

Technical Field

[0001] The present invention relates to the field of grinding equipment, and in particular to an insulating grinding tool for the lead wire of a spindle-shaped coil of a hard winding stator core. Background Art

[0002] During the production of hard winding motors, before the wound spindle-shaped coil is inserted with wires, it is necessary to grind the lead wire on the spindle-shaped coil, process the insulation of the coil lead wire, ensure convenient operation in subsequent processes, thereby improving product quality and reducing the labor intensity of workers.

[0003] For the related technology above, a Chinese patent application with the publication number CN116032049A discloses an electric motor and an electronic device. The electric motor includes: a housing; a stator coil disposed within the housing; a rotor assembly disposed within the housing and capable of rotating relative to the stator coil. The rotor assembly includes a first part and a second part. The first part is coaxially disposed with the stator coil and disposed on one side of the stator coil, and the second part is disposed between the stator coil and the housing; a wire clip that cooperates with the housing to form a channel; and a coil lead wire passing through the channel to guide the coil lead wire from one side of the rotor assembly to the other side based on the channel. The channel formed by the wire clip and the housing is used for the coil lead wire to pass through, guiding the coil lead wire from one end of the rotor assembly to the other end, and at the same time avoiding interference between the coil lead wire and the rotor assembly. The coil lead wire can be led out by the cooperation of a wire clip and the housing.

[0004] In view of the above related technology, when grinding the lead wire, the traditional grinding process mainly involves an operator holding a scraper or other grinding tools for grinding. However, due to the inconsistent lengths of the lead wires of different products, it is difficult to achieve uniform dimensional requirements by manual grinding, which affects product quality. Summary of the Invention

[0005] In order to improve the grinding quality of the lead wire on the spindle-shaped coil, the present application provides an insulating grinding tool for the lead wire of a hard winding stator core spindle-shaped coil.

[0006] The present application provides an insulating grinding tool for the lead wire of a hard winding stator core spindle-shaped coil, adopting the following technical solutions: A hard winding stator core spindle coil lead wire insulating grinding tool, including a frame, a guard is provided with a shield at the upper end of the frame, and two grinding wheels are arranged in the shield, and the axes of the two grinding wheels are parallel and opposite in the vertical direction. The shield is equipped with a motor for driving the rotation of the two grinding wheels. The grinding wheel is detachably connected to the motor. When the motor is working, the rotation direction of the two grinding wheels is opposite. The gap between the two grinding wheels forms a grinding zone, and the height of the grinding zone is adapted to the shuttle coil. The frame is equipped with an adjusting part for adjusting the height of the grinding zone. One side of the shield is hinged vertically. The baffle is opened with a feed port, and the feed port and the grinding zone are right. Yes, a vacuum cleaner is also provided on the side of the shield facing away from the baffle. A vacuum cleaner is connected to the shield. The vacuum cleaner is opposite to the grinding area. A waste box is connected to the vacuum cleaner at the lower end of the frame. The waste box is used to store the dust absorbed by the vacuum cleaner. A material detection part is also provided in the shield. The material detection part is connected to the vacuum cleaner. It is triggered when the material detection part monitors any shuttle coil entering the grinding area. The vacuum cleaner is controlled when the material detection part is triggered. The side of the frame facing away from the vacuum cleaner is also provided with a feed piece for conveying the shuttle coil to the feed port. The shield is provided with a stop block for limiting the shuttle coil.

[0007] 通过采用上述技术方案,打磨引出线时,通过进料件将梭形线圈沿进料口送入护罩内,此时物料检测件触发并带动吸尘器工作。 The motor drives the grinding wheel to rotate. When the shuttlecoil enters the grinding zone, the two grinding wheels cooperate to polish the shuttlecoil. During the grinding process, the shield and the baffle cooperate to prevent the diffusion of dust generated by the grinding. When the vacuum cleaner works, the airflow in the grinding zone is absorbed through the vacuum tube, and the dust is input into the waste box for storage. During the grinding process, the position of the bobbin is limited by the stop block, further improving the grinding accuracy of the bobbin, and setting adjustment parts to adjust the height of the grinding zone at any time, it is convenient to polish the lead wires of different specifications, which is conducive to improving the grinding processing quality of the lead wires on the bobbin.

[0008] Optionally, the motor includes an upper motor and a lower motor. The lower motor is fixedly connected to the frame for driving the rotation of the grinding wheel below. The adjusting member includes a slide rail, a lead screw and a moving seat. The slide rail is fixedly connected to the upper end of the frame in a vertical direction. The moving seat is slidally connected to the slide rail in the length direction of the slide rail. The screw is arranged in the length direction of the slide rail and is rotatably connected to the slide rail about its own axis. The lead screw passes through the movable seat and is threaded to the movable seat. The upper motor is fixedly connected to the side of the movable seat in the transverse direction.

[0009] By adopting the above technical solution, the upper motor and the lower motor respectively drive the two grinding wheels to rotate, so that the grinding wheels grind the shuttle coil. When the grinding wheel is worn and its outer diameter is reduced, the lead screw is rotated to drive the moving seat to move vertically. When the moving seat moves, it drives the upper motor to approach or move away from the lower motor, thereby facilitating the adjustment of the distance between the two grinding wheels, which is suitable for shuttle coils of different specifications.

[0010] Optionally, a wear detection component is fixedly provided in the protective cover, and the wear detection component is connected to the motor. When the wear detection component detects that the wear degree of the grinding wheel reaches a preset value, it is triggered. After the wear detection component is triggered, the motor is controlled to stop working.

[0011] By adopting the above technical solution, when the grinding wheel continues to wear to a state that affects normal operation, the wear detection component is triggered and stops the motor to prompt the operator to replace the grinding wheel, thereby facilitating the monitoring of the grinding wheel and improving ease of use.

[0012] Optionally, the feeding member includes a storage box, a conveying rail, a transport disk and a fixed disk. The storage box is located on the side of the frame facing away from the vacuum cleaner and is used to store a shuttle coil. A transport piece is provided in the storage box. The transport piece is used to drive the shuttle coil in the storage box to lift the shuttle coil. The upper end of the storage box opens the inlet and outlet. The conveying rail is arranged at the upper end of the storage box and extends into the inlet and outlet to the inlet and outlet. The transporting disk is slidably connected to the conveying rail in the length direction of the conveying rail, and the lower end of the transportation disk is provided with a pallet for supporting the shuttle coil. The fixed disk is located on the side of the transportation disk near the shield and is slidably connected to the transportation disk in a vertical direction. When the pallet supports the shuttle coil, the fixed disk is located directly above the shuttle coil, and the lower end of the fixed disk is slidably connected to the shuttle coil.

[0013] By adopting the above technical solution, the material storage box can store the shuttle coil in batches. In the initial state, the transport plate is located far away from the feed port. The uppermost shuttle coil is driven to move upward through the lifting member, and the shuttle coil is placed on the pallet, so that the shuttle coil is opposite to the fixed disk, and the fixed disk is moved downward, so that the fixed disk drives the clamping block into the inner hole of the shuttle coil, and moves the clamping block in the horizontal direction, so that all clamping blocks cooperate to clamp and position the shuttle coil. The transportation disk and the fixed disk cooperate to drive the shuttle coil to move, which is conducive to improving the movement stability of the shuttle coil and improving the feeding convenience of the shuttle coil.

[0014] Optionally, the storage box is slidably connected with a support tray in a vertical direction. The storage box is equipped with a lifting member for driving the movement of the support tray. All the shuttle coils in the storage box are placed above the support tray. The storage box is fixedly connected with several limit rods in a vertical direction. Several limit rods are arranged in the circumference of the support tray. The limit rods pass through the support tray and are slidly connected with the support tray. The shuttle coil is located between all limit rods to restrict the shuttle coil from the support tray.

[0015] By adopting the above technical solution, when the lifting member drives the supporting tray to move, the supporting tray drives all the spindle-shaped coils to lift or lower, which facilitates placing the spindle-shaped coils into the storage box and also facilitates the handling member to lift and transport the uppermost spindle-shaped coil. During the process of moving the spindle-shaped coil, the limiting rod is beneficial to improving the moving stability of the spindle-shaped coil.

[0016] Optionally, the handling member includes a lifting plate, a power member, clamping cylinders and clamping plates. The lifting plate is slidably connected to the storage box in the vertical direction. The power member is located at the lower end of the lifting plate and is fixedly connected to the storage box. The power member is used to drive the lifting plate to move vertically. There are two groups of clamping cylinders. Both groups of clamping cylinders are fixedly connected to the upper end of the lifting plate and are arranged oppositely along the length direction of the conveying rail. The spindle-shaped coils in the storage box are located between the two groups of clamping cylinders. The clamping plates correspond to the clamping cylinders one by one, and the clamping plates are slidably connected to the lifting plate along the length direction of the conveying rail. When the clamping cylinders work, they drive the clamping plates to approach or move away from the spindle-shaped coils.

[0017] By adopting the above technical solution, the power member is used to drive the lifting plate to move vertically. When the lifting plate moves, it drives the clamping cylinders to move. When the two clamping plates are aligned with the uppermost spindle-shaped coil, the two clamping cylinders push the two clamping plates to approach each other, so that the two clamping plates cooperate to clamp and position the spindle-shaped coil. At this time, the power member continues to drive the lifting plate to move, and then drives the spindle-shaped coil to lift through the clamping block.

[0018] Optionally, there are two groups of the supporting plates. The two groups of supporting plates are respectively located on both sides of the transport tray along the width direction of the conveying rail. The line connecting the two supporting plates is perpendicular to the line connecting the two clamping plates, and the distance between the two supporting plates is greater than the length of the clamping plate and less than the outer diameter of the spindle-shaped coil. The supporting plates are slidably connected to the transport tray in the vertical direction. The transport tray is provided with adjusting screws for adjusting the height of the supporting plates.

[0019] By adopting the above technical solution, the adjusting screws are used to adjust the height of the supporting plates in the vertical direction. When the transport tray moves, it drives the supporting plates to move. In the initial state, the two spindle-shaped coils are lifted by the clamping plates so that the lower end faces of the spindle-shaped coils are not lower than the upper end faces of the supporting plates. In the initial state, the transport tray drives the supporting plates to avoid the spindle-shaped coils. When the spindle-shaped coils are lifted to a preset height, the transport tray drives the supporting plates to move to both sides of the spindle-shaped coils and makes the supporting plates located below the spindle-shaped coils. The lifting plate descends so that the spindle-shaped coils contact the supporting plates. At this time, the spindle-shaped coils are aligned with the fixed plate. After clamping and positioning the spindle-shaped coils through the clamping blocks, the clamping plates release the clamping of the spindle-shaped coils, and the lifting plate resets, thus completing the transfer of the spindle-shaped coils.

[0020] Optionally, a guiding disk is fixedly connected to the lower end of the fixed disk. A number of clamping blocks are evenly arranged along the circumference of the guiding disk, and the clamping blocks are slidably connected to the guiding disk in the radial direction of the guiding disk. The outer diameter of the guiding disk is smaller than the inner diameter of the spindle-shaped coil. The fixed disk is slidably connected to a push rod in the vertical direction. The push rod is located between all the clamping blocks. A number of hinge rods are vertically hinged to the lower end of the push rod. The hinge rods correspond to the clamping blocks one by one. The end of the hinge rod away from the push rod is vertically hinged to the corresponding clamping block. An elastic member is provided between the fixed disk and the push rod, and the elastic member applies a downward thrust to the push rod.

[0021] By adopting the above technical solution, the guiding disk guides the clamping blocks. When the push rod moves vertically, the clamping blocks are driven by the hinge rods to move radially along the guiding disk. The elastic member is used to apply a force to the push rod, so that the clamping blocks clamp and position the spindle-shaped coil, which is beneficial to improving the clamping stability of the spindle-shaped coil.

[0022] Optionally, a gear is rotatably connected to the lower end of the transport disk. A toothed ring adapted to the gear is coaxially fixed to the lower end of the fixed disk. The fixed disk is fixedly connected to an arc-shaped plate. The fixed disk is located inside the arc-shaped plate and is slidably connected to the arc-shaped plate in the vertical direction. The inner wall of the arc-shaped plate fits the outer circle of the fixed disk. When the fixed disk moves along the axis of the arc-shaped plate, the toothed ring is driven to engage or disengage with the gear. A handle is fixedly provided on the side of the transport disk away from the protective cover. The end of the handle away from the protective cover is rotatably connected to an adjusting wheel in the horizontal direction. A sprocket group is provided between the gear and the adjusting wheel. When the adjusting wheel rotates, the gear is driven to rotate through the sprocket group.

[0023] By adopting the above technical solution, the handle facilitates the operator to move the transport disk. When it is necessary to rotate the spindle-shaped coil, the operator rotates the adjusting wheel. The adjusting wheel drives the gear to rotate through the sprocket group. When the gear engages with the toothed ring, the gear drives the fixed disk to rotate through the toothed ring, and then drives the spindle-shaped coil to rotate through the clamping blocks, which is beneficial to improving the rotation convenience of the spindle-shaped coil.

[0024] Optionally, a remaining quantity detection member is further provided in the storage box. An alarm is fixedly provided on the storage box. The remaining quantity detection member is electrically connected to the alarm. The remaining quantity detection member is used to detect the number of remaining spindle-shaped coils in the storage box. When the number of remaining spindle-shaped coils is lower than a preset value, the remaining quantity detection member is triggered and a prompt is issued through the alarm.

[0025] By adopting the above technical solution, when processing the spindle-shaped coil, when the number of spindle-shaped coils in the storage box is insufficient, the remaining quantity detection member issues a prompt through the alarm, so that the operator can replenish the materials in time, which is convenient for the operator to control the number of spindle-shaped coils in the storage box.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. When polishing the lead wire, the spindle-shaped coil is fed into the shield through the feeding part along the feeding port. At this time, the material detection part is triggered and drives the vacuum cleaner to work. The motor drives the polishing wheel to rotate. When the spindle-shaped coil enters the polishing area, the two polishing wheels cooperate to polish the spindle-shaped coil. During the polishing process, the shield and the baffle cooperate to block the diffusion of the dust generated by polishing. When the vacuum cleaner works, it sucks the air flow in the polishing area through the suction pipe and inputs the dust into the waste box for storage. During the polishing process, the position of the spindle-shaped coil is restricted by the stop block to further improve the polishing accuracy of the spindle-shaped coil, and the adjusting part is set to adjust the height of the polishing area at any time, which is convenient for polishing lead wires of different specifications and is beneficial to improving the polishing quality of the lead wire on the spindle-shaped coil; 2. The storage box can store the spindle-shaped coils in batches. In the initial state, the transport plate is located at a position far from the feeding port. The lifting part drives the uppermost spindle-shaped coil to move upward, places the spindle-shaped coil on the tray, makes the spindle-shaped coil face the fixed disk, moves the fixed disk downward, makes the fixed disk drive the clamping block to enter the inner hole of the spindle-shaped coil, and moves the clamping block horizontally so that all the clamping blocks cooperate to clamp and position the spindle-shaped coil. The transport disk and the fixed disk cooperate to drive the spindle-shaped coil to move, which is beneficial to improving the movement stability of the spindle-shaped coil and the feeding convenience of the spindle-shaped coil.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to all the attached drawings.

[0033] An embodiment of the present application discloses an insulating grinding tool for the lead wire of a hard-wound stator core spindle-shaped coil.

[0034] Embodiment: Referring to Figure 1 and Figure 2 and, an insulating grinding tool for the lead wire of a hard-wound stator core spindle-shaped coil, includes a frame 1. A shield 11 is fixedly provided at the upper end of the frame 1. One side of the shield 11 along the horizontal direction is provided with an opening, and a baffle 12 is hinged at the opening. The shield 11 is fixedly provided with a quick-release buckle for fixing the baffle 12. The shield 11 is hollow, and two grinding wheels 21 are arranged inside the shield 11. The two grinding wheels 21 are arranged vertically, and the axes of the two grinding wheels 21 are parallel to each other along the horizontal direction. The frame 1 is provided with a motor for driving the two grinding wheels 21 to rotate.

[0035] Referring to Figure 1 and Figure 2, the motor includes an upper motor 221 and a lower motor 222. A vertical plate is fixedly connected to the upper end of the frame 1. The lower motor 222 is fixedly connected to the vertical plate, and the output shaft of the lower motor 222 is coaxially connected to the grinding wheel 21 located below. When the lower motor 222 operates, it drives the corresponding grinding wheel 21 to rotate. An adjusting member is provided above the frame 1. The adjusting member is used to adjust the distance between the two grinding wheels 21. The adjusting member includes a slide rail 31, a lead screw 32, and a moving seat 33. The slide rail 31 is fixedly connected to the side of the vertical plate close to the baffle 12 in the vertical direction. The moving seat 33 is slidably connected to the slide rail 31 along the length direction of the slide rail 31. The upper motor 221 is fixedly connected to the moving seat 33 and thus moves synchronously with the moving seat 33. The lead screw 32 is arranged along the length direction of the slide rail 31 and is rotatably connected to the slide rail 31 around its own axis. The lead screw 32 passes through the moving seat 33 and is threadedly connected to the moving seat 33. When the lead screw 32 rotates, it drives the moving seat 33 to move vertically. A turning handle is fixedly provided at the upper end of the lead screw 32, which is convenient for the operator to rotate the lead screw 32 through the turning handle.

[0036] Referring to Figure 1 and Figure 2 , among the two grinding wheels 21, the upper grinding wheel 21 is coaxially connected to the output shaft of the upper motor 221. When the upper motor 221 operates, it drives the corresponding grinding wheel 21 to rotate. The frame 1 is equipped with a distribution box for supplying power to the upper motor 221 and the lower motor 222. There is a gap between the two grinding wheels 21. The gap here is set as the grinding area. The height of the grinding area is adapted to the spindle-shaped coil, and the size of the grinding area is adjusted by the adjusting member, so as to be applicable to spindle-shaped coils of different sizes, and the position of the grinding wheel 21 is adjusted when the grinding wheel 21 is worn during grinding.

[0037] Referring to Figure 1 and Figure 2 , the baffle 12 is provided with a feeding port 121 in the transverse direction. The feeding port 121 is opposite to the grinding area. When processing the spindle-shaped coil, the operator passes the spindle-shaped coil through the feeding port 121 and sends it into the grinding area. The rotation directions of the two grinding wheels 21 are opposite, so that the two grinding wheels 21 cooperate to grind the spindle-shaped coil. A positioning block 112 is arranged in the protective cover 11. During the grinding process, the positioning block 112 contacts the outer circle of the spindle-shaped coil, thereby positioning the spindle-shaped coil.

[0038] Referring to Figure 1 and Figure 2, a wear detection component 113 is also installed inside the shield 11. In this embodiment, the wear detection component 113 is preferably an infrared induction probe. The wear detection component 113 faces the end face of the grinding wheel 21 along the radial direction. When the grinding wheel 21 is working normally, it is always within the detection range of the wear detection component 113. At this time, the wear detection component 113 remains silent. The wear detection component 113 is electrically connected to both the upper motor 221 and the lower motor 222. When the grinding wheel 21 becomes smaller in diameter due to wear until the end of the grinding wheel 21 moves out of the detection range of the wear detection component 113, the wear detection component 113 is triggered and controls the upper motor 221 and the lower motor 222 to stop, thereby prompting the operator to replace the grinding wheel 21.

[0039] Refer to Figure 1 and Figure 2 , a dust collector 13 is installed on the side of the shield 11 facing away from the baffle 12. A dust suction pipe 131 is connected between the dust collector 13 and the shield 11, and the dust suction pipe 131 faces the grinding area. A material detection component 111 is also arranged inside the shield 11. The material detection component 111 is also an infrared induction probe. The material detection component 111 is electrically connected to the dust collector 13. When the shuttle-shaped coil passes through the feed port 121 and approaches the grinding area, the material detection component 111 is triggered and controls the dust collector 13 to work. During the grinding process of the shuttle-shaped coil, debris and dust are generated, and when the dust collector 13 works, it sucks the dust out of the shield 11 through the dust suction pipe 131.

[0040] Refer to Figure 1 and Figure 2 , a waste box 14 is also installed at the lower end of the frame 1. A waste storage bag is arranged inside the waste box 14. The dust collector 13 is also connected to a discharge pipe, and the discharge pipe passes through the waste box 14 and is connected to the waste storage bag. The dust sucked by the dust collector 13 is discharged into the waste storage bag along the discharge pipe. A full material detection component is also installed on the discharge pipe. The full material detection component is connected to the dust collector 13, the upper motor 221, and the lower motor 222. When the full material detection component detects that the waste box 14 is full of waste, it is triggered and then controls the dust collector 13, the upper motor 221, and the lower motor 222 to stop, so as to prompt the operator to clean the waste box 14. In this embodiment, the full material detection component is selected as a pressure induction sensor for detecting the air pressure in the discharge pipe. When the waste box 14 is full of dust, when the dust collector 13 conveys air flow into the waste storage bag, the air flow in the waste storage bag is blocked by the dust and is difficult to discharge, thereby increasing the air pressure in the discharge pipe and triggering the pressure induction sensor.

[0041] Refer to Figure 1 and Figure 3, on one side of the frame 1, a feeding member 4 is further provided. The feeding member 4 is located on the side of the shield 11 where the baffle 12 is provided. The feeding member 4 includes a storage box 41. The storage box 41 is hollow, and an inlet and outlet 411 is provided at the upper end of the storage box 41. A supporting tray 412 is slidably connected to the inside of the storage box 41 along the vertical direction. The supporting tray 412 is horizontally arranged, and the outer diameter of the supporting tray 412 is larger than the outer diameter of the shuttle-shaped coil. The storage box 41 is further equipped with a lifting member 413 for driving the supporting tray 412 to move. The lifting member 413 includes a screw rod, a moving motor, and a guiding rod. The guiding rod is fixedly connected to the inside of the storage box 41 along the vertical direction, and the guiding rod passes through the supporting tray 412 and is slidably connected to the supporting tray 412.

[0042] Referring to Figure 3 and Figure 4 , the screw rod is arranged parallel to the guiding rod, and the screw rod is rotatably connected to the storage box 41 around its own axis. The screw rod passes through the supporting tray 412 and is threadedly connected to the supporting tray 412. The moving motor is installed at the lower end of the storage box 41 and is used to drive the screw rod to rotate. Under the limiting action of the guiding rod, when the screw rod rotates, it drives the supporting tray 412 to move vertically. The shuttle-shaped coil is placed above the supporting tray 412 through the inlet and outlet 411, so that the supporting tray 412 drives the shuttle-shaped coil to move vertically.

[0043] Referring to Figure 3 and Figure 4 , a remaining amount detecting member 415 is arranged inside the storage box 41. The remaining amount detecting member 415 is selected as an infrared induction probe. The infrared induction probe is arranged horizontally opposite to the shuttle-shaped coil. The remaining amount detecting member 415 is used to detect the remaining amount of the shuttle-shaped coil in the storage box 41. The supporting tray 412 drives all the shuttle-shaped coils to rise in sequence. When the supporting tray 412 drives all the shuttle-shaped coils to move out of the induction range of the remaining amount detecting member 415, the remaining amount detecting member 415 is triggered. An alarm 416 is installed outside the storage box 41. After the remaining amount detecting member 415 is triggered, a prompt is sent through the alarm 416, thereby reminding the operator to replenish the material.

[0044] Referring to Figure 3 and Figure 4 , a plurality of limiting rods 414 are fixedly connected inside the storage box 41. The limiting rods 414 are arranged along the moving direction of the supporting tray 412, and the length of the limiting rods 414 is greater than the moving range of the supporting tray 412. The plurality of limiting rods 414 surround the supporting tray 412 circumferentially. The shuttle-shaped coils inside the storage box 41 are located between the plurality of limiting rods 414. All the limiting rods 414 cooperate to limit the shuttle-shaped coils on the supporting tray 412, thereby improving the moving stability of the shuttle-shaped coils.

[0045] Referring to Figure 3 and Figure 4, a handling member is further provided in the storage bin 41. The handling member includes a lifting plate 451, a power member 452, a clamping cylinder 453, and a clamping plate 454. The lifting plate 451 is slidably connected to the storage bin 41 in the vertical direction, and an avoidance opening is vertically opened at the middle position of the lifting plate 451. All the limiting rods 414 are located within the avoidance opening. The power member 452 is located below the lifting plate 451 and fixedly connected to the storage bin 41. The power member 452 is an electric push rod 443, which is used to drive the lifting plate 451 to move vertically. There are two clamping cylinders 453, and the two clamping cylinders 453 are arranged along the direction from the frame 1 to the storage bin 41, and the two clamping plates 454 are both installed above the lifting plate 451.

[0046] Refer to Figure 3 and Figure 4 , when the lifting plate 451 moves, it drives the two clamping plates 454 to move. The two clamping plates 454 correspond to the clamping cylinders 453 one by one, and the clamping plates 454 are fixedly connected to the output ends of the clamping cylinders 453. All the spindle-shaped coils in the storage bin 41 are located between the two clamping plates 454. When the clamping cylinders 453 work, they drive the clamping plates 454 to approach or move away from the spindle-shaped coils. A guiding rod is fixedly connected to the upper end of the lifting plate 451 along the moving direction of the clamping plate 454. The guiding rod passes through the clamping plate 454 and is slidably connected to the clamping plate 454, which is beneficial to improving the moving stability of the clamping plate 454.

[0047] Refer to Figure 3 and Figure 4 , the clamping plate 454 extends in the direction away from the lifting plate 451. When the lifting plate 451 reaches the uppermost end of the moving range, the upper end of the clamping plate 454 extends out of the storage bin 41 along the inlet / outlet 411. A flexible block 455 is fixedly provided on the side of the clamping plate 454 close to the spindle-shaped coil. The flexible block 455 is made of rubber. When processing the spindle-shaped coil, by moving the lifting plate 451, the flexible block 455 is aligned with the uppermost spindle-shaped coil in the storage bin 41. The two clamping cylinders 453 push the clamping plates 454 to approach the spindle-shaped coil, so that the two flexible blocks 455 cooperate to clamp and position the spindle-shaped coil. The lifting plate 451 continues to rise, thereby driving the corresponding spindle-shaped coil to rise from the inlet / outlet 411.

[0048] Refer to Figure 3 and Figure 4, the feeding part 4 further includes a conveying rail 42, a transport tray 43 and a fixed tray 44. The conveying rail 42 is located at the upper end of the storage bin 41 and is arranged in the direction pointing from the inlet and outlet 411 to the feeding port 121. One side of the conveying rail 42 away from the storage bin 41 passes through the feeding box and extends into the shield 11. The projection of the conveying rail 42 on the horizontal plane is located outside the inlet and outlet 411. When the handling part drives the shuttle-shaped coil to lift, the shuttle-shaped coil does not interfere with the conveying rail 42. The transport tray 43 is slidably connected to the conveying rail 42 along the length direction of the conveying rail 42, and two sets of supporting plates 431 are arranged at the lower end of the transport tray 43. The two supporting plates 431 are respectively located on both sides of the transport tray 43 along the width direction, and the supporting plates 431 are slidably connected to the transport tray 43 vertically. When the transport tray 43 moves, it drives the supporting plates 431 to move synchronously.

[0049] Refer to Figure 3 and Figure 4 , a regulating screw 432 is rotatably connected to the upper end of the supporting plate 431. The regulating screw 432 passes through the transport tray 43 and is threadedly connected to the transport tray 43. When the operator rotates the regulating screw 432, the regulating screw 432 drives the supporting plate 431 to rise or fall, thereby facilitating the adjustment of the vertical height of the supporting plate 431. The distance between the two supporting plates 431 is smaller than the outer diameter of the shuttle-shaped coil and larger than the length of the clamping plate 454. After the clamping plate 454 drives the shuttle-shaped coil to rise, the transport tray 43 is moved along the conveying rail 42 so that the two supporting plates 431 move below the shuttle-shaped coil. At this time, the lifting plate 451 moves downward, and the clamping block 441 drives the shuttle-shaped coil to approach the supporting plate 431. A plurality of supporting balls 438 are rotatably connected to the upper end of the supporting plate 431. When the shuttle-shaped coil contacts the supporting balls 438, the plurality of supporting balls 438 cooperate to support the shuttle-shaped coil.

[0050] Refer to Figure 1 and Figure 4 , the fixed tray 44 is located on the side of the transport tray 43 close to the shield 11. An arc-shaped plate 434 is fixedly connected to the position of the transport tray 43 close to the shield 11. The arc-shaped plate 434 is arranged vertically. The fixed tray 44 is located inside the arc-shaped plate 434 and is slidably connected to the arc-shaped plate 434 vertically. The arc-shaped plate 434 limits the fixed tray 44, and while guiding the fixed tray 44 to move vertically, it supports the fixed tray 44 to rotate around its own axis. A guide disk 442 is fixedly connected to the lower end of the fixed tray 44. The diameter of the guide disk 442 is smaller than the inner diameter of the shuttle-shaped coil. A plurality of clamping blocks 441 are arranged along the circumferential direction of the guide disk 442. The clamping blocks 441 are slidably connected to the guide disk 442 along the diameter direction of the guide disk 442. A push rod 443 is slidably connected to the fixed tray 44 vertically. The push rod 443 is located between all the clamping blocks 441, and the lower end of the push rod 443 is hinged vertically with a hinge rod 444. One end of the hinge rod 444 away from the push rod 443 is hinged vertically with the corresponding clamping block 441.

[0051] Refer toFigure 1 and Figure 4 When the push rod 443 moves vertically, it drives the clamping block 441 to approach or move away from the axis of the guide disk 442 through the hinge rod 444. An elastic member 445 is fixedly connected between the push rod 443 and the fixed disk 44. The elastic member 445 is a spring. One end of the spring is fixedly connected to the push rod 443, and the other end is fixedly connected to the fixed disk 44. When moving the transport disk 43 above the shuttle-shaped coil, the fixed disk 44 is moved upward along the arc plate 434 so that the guide disk 442 avoids the shuttle-shaped coil. When the shuttle-shaped coil is above the support plate 431 and is directly opposite to the fixed disk 44, the fixed disk 44 is moved downward.

[0052] Refer to Figure 3 and Figure 4 Refer to

[0053] Refer to Figure 3 and Figure 4 During the downward movement of the fixed disk 44, the push rod 443 is in a position away from the guide disk 442. At this time, the elastic member 445 is deformed and applies a vertically downward force to the push rod 443. At this time, the clamping block 441 is in a position close to the axis of the guide disk 442. When the guide disk 442 drives all the clamping blocks 441 into the inner side of the shuttle-shaped coil, under the action of gravity and the elastic member 445, the push rod 443 is moved downward, and further all the clamping blocks 441 move in a direction away from the axis of the guide disk 442. After the clamping block 441 abuts against the inner wall of the shuttle-shaped coil, it positions the shuttle-shaped coil. At this time, the side of the shuttle-shaped coil close to the shield 11 is located outside the transport disk 43 and the fixed disk 44.

[0054] Refer to Figure 3 and Figure 4, a handle 435 is fixedly connected to the upper end of the transport tray 43. The handle 435 is located on the side of the transport tray 43 away from the shield 11, and the handle 435 facilitates the operator to move the transport tray 43. A regulating wheel 436 is rotatably connected to the side of the handle 435 away from the transport tray 43. A sprocket group 437 is provided between the regulating wheel 436 and the gear 433. When the operator rotates the regulating wheel 436, the adjusting screw drives the gear 433 to rotate through the sprocket group 437. The gear 433 drives the fixed disk 44 to rotate through the toothed ring. When the fixed disk 44 rotates, the shuttle-shaped coil is driven to rotate through the cooperation of the guide disk 442 and the clamping block 441, thereby facilitating the adjustment of the angle of the shuttle-shaped coil. During this process, the support ball 438 is beneficial to reducing the friction between the tray 431 and the shuttle-shaped coil and improving the rotation convenience of the shuttle-shaped coil.

[0055] Referring to Figure 1 and Figure 3 , when the shuttle-shaped coil needs to be polished, the transport tray 43 is moved towards the shield 11 through the handle 435, so that one side of the transport tray 43 drives the shuttle-shaped coil to enter the polishing area for polishing. A stopper 439 is fixedly connected to one side of the transport tray 43. The conveying rail 42 is provided with a positioning block 421 facing the stopper 439. The positioning block 421 is slidably connected to the conveying rail 42 along the length direction of the conveying rail 42. A moving screw 422 is rotatably connected to the conveying rail 42. The moving screw 422 is arranged along the length direction of the conveying rail 42. The moving screw 422 passes through the positioning block 421 and is threadedly connected to the positioning block 421. The moving screw 422 positions the positioning block 421. When the transport tray 43 is moved towards the shield 11, the transport tray 43 drives the stopper 439 to approach the positioning block 421. When the stopper 439 contacts the positioning block 421, the transport tray 43 stops. At this time, the shuttle-shaped coil is in a preset polishing position, which is beneficial to improving the polishing accuracy.

[0056] The implementation principle of a tooling for insulating and grinding the lead wire of a spindle-shaped coil of a hard-wound stator core in an embodiment of the present application is as follows: The spindle-shaped coils are stored in batches in a storage box 41 for easy access by operators. During the feeding process, by setting a clamping plate 454 and a transport tray 43, the lifting and handling of the spindle-shaped coils are automated. When the spindle-shaped coil is placed on the transport tray 43, a fixed plate 44 clamps and positions the spindle-shaped coil through a clamping block 441. Then, when an operator rotates an adjusting wheel 436, the adjusting wheel 436 drives a gear 433 to rotate through a sprocket group 437, causing the gear 433 to drive the fixed plate 44 to rotate through cooperation with a toothed ring. The fixed plate 44 drives the spindle-shaped coil to rotate on a support plate 431 through the clamping block 441 to adjust the grinding position of the spindle-shaped coil. Move the transport tray 43 along a conveying rail 42, and the transport tray 43 drives the spindle-shaped coil to pass through a feed port 121 and enter a grinding area. After the spindle-shaped coil enters a shield 11, a material detection component 111 is triggered and drives a dust collector 13 to work. When the spindle-shaped coil enters the grinding area, two grinding wheels 21 cooperate to grind the spindle-shaped coil. At this time, the dust collector 13 absorbs the dust generated during the grinding process through a suction pipe 131. When the grinding wheels 21 are worn, the distance between the two grinding wheels 21 can be adjusted by rotating a lead screw 32. By setting a wear detection component 113, it is convenient to monitor the wear degree of the grinding wheels 21 and facilitate timely replacement of the grinding wheels 21. During the grinding process, a stop block 112 restricts the spindle-shaped coil, which is beneficial to improving the grinding accuracy of the spindle-shaped coil. At the same time, during the grinding process, there is no need for an operator to hold the spindle-shaped coil by hand, which is beneficial to further improving the grinding convenience and the grinding quality of the lead wire on the spindle-shaped coil.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
