Description

Technical Field

[0001] The present application relates to the technical field of motor core production, and in particular to a lamination tool for motor rotor cores. Background Art

[0002] With the acceleration of industrialization and the continuous advancement of science and technology, the performance and efficiency of electric motors, as important devices for energy conversion, are receiving increasing attention. The performance of electric motors depends largely on the structure and manufacturing process of their rotor cores. The rotor core is the core component of the motor rotor. Its main function is to support the windings and provide a magnetic circuit, which affects key performance indicators such as the motor's efficiency, power factor, and temperature rise. The rotor core is composed of several stampings stacked layer by layer to a certain thickness. During the manufacture of the core, a tooling is required to ensure the accuracy of the stacking of the rotor stampings and the uniformity of the slot shape.

[0003] However, in the prior art, when stacking a number of rotor punchings, workers often use a square to position the rotor punchings against the outer diameter slots of the rotor punchings. Since the square base is small, it is easy to cause the core to twist and deform for a high iron core. This reduces the verticality of the core and the coaxiality of the slot, thereby affecting the accuracy and quality of the rotor core. Summary of the Invention

[0004] The purpose of the present invention is to improve the verticality of the rotor core and the coaxiality of the slots, thereby improving the precision and quality of the rotor core.

[0005] The present application provides a lamination tool for a motor rotor core, which adopts the following technical solution:

[0006] A laminating tool for a motor rotor core, comprising a laminating base plate, a lower base plate pad being mounted on the laminating base plate, and a rotor core shaft fixing plate being provided on the lower base plate pad;

[0007] The rotor core shaft fixing plate is provided with a rotor lower base plate, the rotor lower base plate abuts and fits with the bottom of the rotor iron core, the rotor core shaft is detachably connected to the rotor core shaft fixing plate, the rotor core shaft is vertically arranged, the rotor core shaft is passed through the rotor lower base plate, and the rotor core shaft is passed through the rotor punching; a plurality of positioning rulers are slidably provided on the stacked base plate, and a positioning member for positioning the positioning rulers is provided on the stacked base plate; two main positioning plates are fixedly provided on one side of the positioning ruler close to the rotor punching, and the two main positioning plates can be respectively inserted into two grooves on the edge of the rotor punching;

[0008] A rotor upper base plate is vertically slid on the stacked base plate, and the rotor upper base plate abuts and fits against the top of the rotor core; a locking screw 1 is vertically arranged on the rotor lower base plate, and the locking screw 1 passes through the rotor core, and the rotor upper base plate and the rotor lower base plate are locked by the locking screw 1.

[0009] By adopting the above technical solution, the staff first installs the lower base plate pad on the stacked base plate, then installs the bottom end of the rotor base plate positioning shaft on the lower base plate pad, then places the rotor core shaft fixing plate on the lower base plate pad, and inserts the rotor base plate positioning shaft into the positioning groove on the rotor core shaft fixing plate; then the rotor core shaft is placed vertically and its bottom end is installed on the rotor core shaft fixing plate, then the positioning ruler and the main positioning plate are moved to the appropriate position, then multiple rotor punchings are stacked, and the rotor core shaft is inserted into the central through-hole of the rotor punching, and the two main positioning plates are inserted into the grooves on the edges of the rotor punching;

[0010] When the rotor sheets are stacked to a certain height, insert locking screw 1 into the through hole on the rotor sheet and lock the bottom end of locking screw 1 to the rotor lower base plate to ensure the alignment of the rotor sheets. Then move the rotor upper base plate downward until the rotor core shaft and locking screw 1 are simultaneously inserted into the rotor upper base plate and the rotor upper base plate abuts against the top of the stacked rotor core. Finally, screw the nut into the top of locking screw 1 and use a torque wrench to apply the torque to lock the rotor upper and lower base plates. Move the positioning ruler to a position away from the rotor core and finally perform diagonal welding on the rotor core as required.

[0011] After welding is completed, the nut can be loosened to remove the iron core. The whole process improves the accuracy of rotor punching stacking, improves the coaxiality of the rotor punching, improves the coaxiality and uniformity of the rotor punching groove type, and improves the verticality of the rotor punching.

[0012] Preferably, a rotor lower pressure plate is installed on the rotor lower base plate, and the rotor lower pressure plate abuts against the bottom of the rotor core. A rotor upper pressure plate is installed on the bottom of the rotor upper base plate, and the rotor upper pressure plate abuts against the top of the rotor core.

[0013] By adopting the above technical solution, the upper and lower finger pressure plates are used to fix the position of the rotor core, ensure the concentricity of the core and the rotating shaft, and prevent the core from axial or radial movement during the operation of the motor; at the same time, it helps to dissipate heat from the rotor core and reduce the temperature rise of the motor; at the same time, during the operation of the motor, the upper and lower finger pressure plates can also absorb part of the vibration, reduce the noise and loss caused by vibration, and extend the service life of the motor.

[0014] Preferably, a locking screw rod 2 is vertically provided between the rotor lower base plate and the rotor upper base plate, and the upper and lower ends of the locking screw rod 2 are respectively passed through the rotor lower base plate and the rotor upper base plate, and are both locked by nuts; a positioning feeler gauge is fixedly provided on the side wall of the locking screw rod 2, and the positioning feeler gauge is inserted into the groove on the edge of the rotor core.

[0015] By adopting the above technical solution, the provided positioning feeler gauge can further improve the accuracy and coaxiality of the groove profile of the stacked rotor punchings, and further improve the verticality of the multiple stacked rotor punchings.

[0016] Preferably, the positioning ruler includes a sliding base, a main positioning square tube and a square tube welding plate, the bottom end of the main positioning square tube is fixedly set on the sliding base, the square tube welding plate is fixedly set on the side of the main positioning square tube close to the rotor core, and the side of the square tube welding plate close to the rotor core is vertically slid with a support block for placing rotor punchings, and the square tube welding plate is provided with a driving mechanism for driving the support block.

[0017] By adopting the above technical solution, when the rotor punching is large in size and weight, after the staff inserts the rotor punching onto the rotor core shaft, the rotor punching can fall naturally under the action of its own gravity. However, the rotor punching may deflect during the falling process and may get stuck on the rotor core shaft. In this case, the staff needs to change the position of the rotor punching so that the rotor punching can fall smoothly, thereby improving the staff's work intensity.

[0018] Therefore, after the staff has inserted the rotor punching onto the rotor core shaft, since the support block is at the top position of the square tube welding plate at this time, the rotor punching can be placed on multiple support blocks, and then the multiple support blocks can be driven to move downward at the same time by the driving mechanism, and the rotor punching can move downward with the multiple support blocks until it is superimposed on the rotor punching at the bottom. Then, the support block can be moved back to the top position of the square tube welding plate under the action of the driving mechanism to facilitate the transportation of the next rotor punching. Multiple support blocks move downward at the same time, which reduces the possibility of the rotor punching being deflected, thereby increasing the possibility of the rotor punching being smoothly lowered, thereby reducing the work intensity of the staff.

[0019] Preferably, the driving mechanism includes a conveyor belt, a spring, a block and a driving motor. A plurality of rollers are arranged in the square tube welding plate and rotate in sequence along the vertical direction. The conveyor belt is arranged vertically and is driven by the rollers.

[0020] The two ends of the spring are respectively fixed to the conveyor belt and the support block, the stop block is horizontally slidably arranged at the bottom of the support block, and the stop block vertically slides on the square tube welding plate, and the bottom of the support block is vertically slid with an abutment block, and a pushing member 1 is provided in the support block for pushing the abutment block to move, the abutment block can abut the top of the rotor punching, and the side wall of the abutment block abuts the stop block; the driving motor is installed on the side wall of the square tube welding plate, and the driving motor shaft is fixedly arranged at one end of one of the rollers; a push plate is fixedly provided on the top of the square tube welding pipe, and the push plate is provided with an inclined surface, and the push plate is slidably engaged with the support block through the inclined surface; the driving mechanism also includes a control component for controlling the driving motor.

[0021] By adopting the above technical solution, as multiple rotor punchings are continuously stacked, the height of the rotor core gradually increases. Therefore, when it is necessary to drive the support block to descend, the staff first turns on the motor, the motor can drive the roller to rotate, the roller can drive the belt for transmission, and the belt can drive the support block to move downward. At this time, the spring 1 is in a stretched state, and the abutment block abuts against the stop block. Then, when the support block moves to the upper position close to the bottom rotor punching, the abutment block can contact the bottom rotor punching and gradually move into the support block. Then, the elastic force of the spring 1 can pull the support block to a position away from the rotor punching until the support block moves away from the rotor punching. The position of the support block can be triggered by the control component to control the motor-driven roller to reverse during the movement, so that the belt is driven in the opposite direction, and the support block can move upward to the top position of the square tube welding plate. The support block can contact the push plate during the rising process, and then when the support block continues to rise, the push plate can push the support block to move in the direction close to the rotor punching through the inclined surface. The spring is stretched, and when the support block drives the abutment block to move to a position away from the stop block, the abutment block can be moved out to the outside of the support block under the action of the pusher. At this time, the abutment block can abut on the stop block again, which makes it convenient for the support block to repeatedly transport the rotor punching according to the height of the rotor core.

[0022] Preferably, a vibration block 1 is vertically slidably provided on the support block, a rotor punching is in contact with the top of the vibration block 1, and a first vibration assembly is provided on the square tube welded pipe; the first vibration assembly comprises a second spring, a gear, a rack, a first connecting pipe, a cam and a rotating rod, the two ends of the second spring are respectively fixedly provided on the support block and the first vibration block, the gear is rotatably provided on the conveyor belt, the rack is vertically fixedly provided on the side wall of the square tube welded plate, and the gear is meshed with the rack;

[0023] The connecting tube 1 is rotatably arranged on the supporting block, the cam is arranged between the vibrating block 1 and the supporting block, and is fixedly arranged on the connecting tube 1; one end of the rotating rod is fixedly arranged on the gear, and the other end of the rotating rod is inserted into the connecting tube 1, and a guide block is fixedly arranged on the side wall of the rotating rod, and a guide groove 1 is opened along the axial direction of the inner wall of the connecting tube 1 for the sliding movement of the guide block.

[0024] By adopting the above technical solution, the staff first places the rotor punching on the vibration block 1. When the belt drives the support block to move in the vertical direction, the rack can drive the gear to rotate, the gear drives the rotating rod to rotate, the rotating rod drives the guide block to rotate, the guide block can drive the connecting pipe 1 to rotate, the connecting pipe drives the cam to rotate, and the side wall of the cam can drive the vibration block 1 to move back and forth in the vertical direction. The spring 2 is continuously stretched, and the vibration block 1 continuously vibrates the rotor punching, thereby further reducing the difficulty of lowering the rotor punching.

[0025] Preferably, a clamping block is horizontally slidably provided on the top of the vibration block 1, and a slope is provided on the top of the clamping block. The clamping block is fitted with the bottom side wall of the rotor punching through the slope sliding, and the clamping block abuts against the top of the rotor punching. A pushing member 2 for pushing the clamping block to move is provided on the vibration block 1.

[0026] By adopting the above technical solution, when the staff places the rotor punching on the vibration block one, the gravity of the rotor punching can push the clamping block to move through the inclined surface on the clamping block. When the rotor punching abuts against the vibration block one, the clamping block can be moved to the upper position of the rotor punching under the action of the pusher two, thereby clamping the rotor punching, and then the rotor punching can be moved downward with the support block, further reducing the difficulty of the rotor punching to descend.

[0027] Preferably, a secondary positioning wedge-shaped key for positioning the rotor core is horizontally slidably provided on the stacked bottom plate, and the secondary positioning wedge-shaped key can be inserted into a groove on the side wall of the rotor core. A movable component is also provided on the stacked bottom plate;

[0028] The moving assembly includes a driving rod and a slide plate. The slide plate slides horizontally on the stacked base plate, and the bottom end of the secondary positioning wedge key is fixedly set on the slide plate. One end of the driving rod is fixedly set on the sliding base. A connecting rod is provided between the driving rod and the slide plate, and the two ends of the connecting rod are respectively hinged to the driving rod and the slide plate.

[0029] By adopting the above technical solution, before the positioning ruler moves toward the direction close to the rotor punching, the secondary positioning wedge key is located away from the rotor punching. When the positioning ruler moves toward the direction close to the rotor punching, it can drive the driving rod to move, and the driving rod can drive the connecting rod to rotate. The connecting rod can drive the slide plate and the secondary positioning wedge key to move toward the rotor punching at the same time until the secondary positioning wedge key is inserted into the groove on the edge of the rotor punching, thereby further improving the coaxiality and accuracy of the rotor core slot, and further improving the verticality of the rotor core.

[0030] Preferably, a second vibration block is vertically slidably provided at the bottom of the lower base plate of the rotor, and the second vibration block can abut against the bottom of the lower base plate of the rotor; a push block is vertically slidably provided at the bottom of the slide plate, and the second vibration block vertically slides on the push block; a third spring is provided between the slide plate and the push block, and the two ends of the third spring are respectively fixedly provided on the slide plate and the push block; a fourth spring is provided between the second vibration block and the push block, and the two ends of the fourth spring are respectively fixedly provided on the second vibration block and the push block; a second vibration component for vibrating the second vibration block is provided on the stacked base plate.

[0031] By adopting the above technical solution, when the rotor punching sheets are stacked, the upper base plate of the rotor can be driven to move downward. During the descending process of the rotor upper base plate, the second vibration component can be triggered. The second vibration component can drive the push block and the second vibration block to move back and forth in the vertical direction. The second vibration block can vibrate the lower base plate of the rotor, thereby making the punching sheets of the rotor core fit tightly together, reducing the gaps between the punching sheets, improving the stiffness and mechanical strength of the rotor, and helping the punching sheets to achieve better contact before welding, thereby improving the quality and consistency of welding; at the same time, it can partially release the internal stress generated in the iron core, reducing the risk of deformation or damage of the rotor during use; when the secondary positioning wedge key is away from the rotor core, the reset member provided can make the threaded rod move to the initial position, so as to facilitate the next drive of the rotor lower base plate to vibrate.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. The staff first installs the lower base plate pad on the stacking base plate, then installs the bottom end of the rotor base plate positioning shaft on the lower base plate pad. Then, the rotor core shaft fixing plate is placed on the lower base plate pad and the rotor base plate positioning shaft is inserted into the positioning groove on the rotor core shaft fixing plate. The rotor core shaft is then placed vertically and its bottom end is installed on the rotor core shaft fixing plate. The positioning ruler and main positioning plate are then moved to the appropriate position and limited by the positioning parts. Then, multiple rotor punchings are stacked, and the rotor core shaft is inserted into the center through-hole of the rotor punching. The two main positioning plates are inserted into the grooves on the edges of the rotor punchings.

[0036] When the rotor sheets are stacked to a certain height, insert locking screw 1 into the through hole on the rotor sheet and lock the bottom end of locking screw 1 to the rotor lower base plate to ensure the alignment of the rotor sheets. Then move the rotor upper base plate downward until the rotor core shaft and locking screw 1 are simultaneously inserted into the rotor upper base plate and the rotor upper base plate abuts against the top of the stacked rotor core. Finally, screw the nut into the top of locking screw 1 and use a torque wrench to apply the torque to lock the rotor upper and lower base plates.

[0061] The upper and lower finger pressure plates are used to fix the position of the rotor core, ensure the concentricity of the core and the shaft, and prevent the core from axial or radial movement during motor operation; at the same time, they help dissipate heat from the rotor core and reduce the temperature rise of the motor; at the same time, during motor operation, the upper and lower finger pressure plates can also absorb some vibrations, reduce noise and losses caused by vibration, and extend the service life of the motor.

[0062] A locking screw 17 is vertically provided between the rotor lower base plate 6 and the rotor lower base plate 6.

[0066] like Figure 3 and Figure 5 As shown, when the sliding base 81 moves to the position corresponding to the limiting block 21 and the limiting groove 24 on the fixed block 23, the limiting block 21 can be pushed to be inserted into the limiting groove 24, thereby limiting the sliding base 81 and then limiting the positioning ruler 8.

[0067] like Figure 3 and Figure 4 As shown, when the rotor punching is large in size and weight, after the staff inserts the rotor punching onto the rotor core shaft 7, the rotor punching can fall naturally under the action of its own gravity. However, the rotor punching may deflect during the falling process and may get stuck on the rotor core shaft 7. In this case, the staff needs to change the position of the rotor punching so that the rotor punching can fall smoothly, which increases the staff's work intensity.

[0068] like Figure 3 and Figure 4As shown, therefore, after the staff has passed the rotor punching through the rotor core shaft 7, since the support block 19 is at the top position of the square tube welding plate 83 at this time, the rotor punching can be placed on multiple support blocks 19, and then the multiple support blocks 19 can be driven by the driving mechanism 20 to move downward at the same time, and the rotor punching can move downward with the multiple support blocks 19 until it is superimposed on the rotor punching at the bottom, and then the support block 19 can be moved back to the top position of the square tube welding plate 83 under the action of the driving mechanism 20 to facilitate the transportation of the next rotor punching. Multiple support blocks 19 move downward at the same time, which reduces the possibility of the rotor punching being deflected, thereby increasing the possibility of the rotor punching falling smoothly, and thereby reducing the work intensity of the staff.

[0069] like Figure 4 、 Figure 5 and Figure 6 As shown, the driving mechanism 20 includes a conveyor belt 201, a spring 202, a block 203 and a driving motor 204. A storage groove 205 is provided on the side of the square tube welding plate 83 close to the rotor core in the vertical direction. A plurality of rollers 206 are provided on the inner wall of the storage groove 205 so as to rotate in sequence in the vertical direction. The conveyor belt 201 is arranged vertically and is driven by the rollers 206.

[0070] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the two ends of spring 1 202 are respectively fixedly arranged on the conveyor belt 201 and the support block 19, and the spring 1 202 is provided with a guard rod 1 38, one end of the guard rod 1 38 is fixedly connected to the support block 19, and the other end of the guard rod 1 38 is passed through and slides on the side wall of the conveyor belt 201; the stopper 203 slides horizontally on the bottom of the support block 19, and the top of the stopper 203 is fixedly connected to two connecting rods 207, which are T-shaped rods. The bottom of the support block 19 is provided with two T-shaped slots 208 for the T-shaped rods to slide, and the T-shaped slots 208 extend horizontally along the length direction of the support block 19; and the stopper 203 slides vertically on the side wall of the square tube welded plate 83, and the opposite sides of the stopper 203 are fixedly connected with sliders 209, and the inner walls of the opposite ends of the storage groove 205 are provided with sliding grooves 210 for the sliding of sliders 209 along the vertical direction.

[0071] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, there is an abutment block 211 at the bottom of the support block 19 for vertical sliding. A pushing member 1 is provided in the support block 19 for pushing the abutment block 211 to move. The pushing member 1 is a pushing spring 12. The two ends of the pushing spring 12 are fixedly connected to the abutment block 211 and the inner wall of the support block 19 respectively; the abutment block 211 can abut the top of the rotor punching, and the side wall of the abutment block 211 abuts the stopper 203; the driving motor 204 is installed on the side wall of the square tube welded tube, and the driving motor 204 rotating shaft is fixedly set at one end of the bottom roller 206 located in the storage groove 205; the top inner wall of the storage groove 205 is fixedly connected to a push plate 213, and the push plate 213 is provided with an inclined surface on the side close to the support block 19, and the push plate 213 is slidably engaged with the support block 19 through the inclined surface; the driving mechanism 20 also includes a control component 214 for controlling the driving motor 204.

[0072] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the control component 214 includes an infrared sensor 2141 and a controller 2142. The infrared sensor 2141 is installed on the bottom inner wall of the storage tank 205, and the controller 2142 is installed on the square tube welding plate 83. The input end of the controller 2142 is electrically connected to the output end of the infrared sensor 2141 to receive the infrared sensing signal; the control end of the controller 2142 is electrically connected to the control end of the drive motor 204 to control the operation of the drive motor 204 in response to the infrared sensing signal.

[0073] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, due to the continuous stacking of multiple rotor punchings, the height of the rotor core gradually increases. Therefore, when it is necessary to drive the support block 19 to descend, the staff first turns on the drive motor 204. The drive motor 204 can drive the roller 206 to rotate, and the roller 206 can drive the belt for transmission. The belt can drive the support block 19 to move downward. At this time, the spring 1 202 is in a stretched state, and the abutment block 211 abuts against the stop block 203. Then, when the support block 19 moves to the upper position close to the bottom rotor punching, the abutment block 211 can contact the bottom rotor punching and gradually move into the support block 19. Then, the elastic force of the spring 1 202 can pull the support block 19 to a position away from the rotor punching until the support block 19 moves to a position away from the rotor punching.

[0074] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, when the support block 19 moves into the storage slot 205, the infrared sensor 2141 can detect the support block 19 and transmit an infrared sensing signal to the controller 2142. Then the controller 2142 can control the drive motor 204 to drive the roller 206 to reverse, thereby making the belt drive in the opposite direction, and the support block 19 can move upward to the top position of the square tube welding plate 83. During the rising process, the support block 19 can contact the push plate 213. Then, when the support block 19 continues to rise, the push plate 213 can push the support block 19 to move in the direction close to the rotor punching through the inclined surface. The spring 1 202 is stretched. When the support block 19 drives the abutment block 211 to move to a position away from the stop block 203, the abutment block 211 can be moved out to the outside of the support block 19 under the action of the push member 1. At this time, the abutment block 211 can once again abut on the stop block 203, which can facilitate the repeated transportation of the rotor punching by the support block 19 according to the height of the rotor core.

[0075] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a vibration block 25 slides vertically on the top of the support block 19, and the rotor punching abuts against the top of the vibration block 25. A first vibration component 26 is provided on the square tube welded tube; the first vibration component 26 includes a spring 261, a gear 262, a rack 263, a connecting tube 264, a cam 265 and a rotating rod 266. There are multiple springs 261, and they are all vertically arranged. The upper and lower ends and both ends of the spring 261 are respectively fixed to the support block 19 and the vibration block 25; a telescopic rod 267 is vertically arranged in the spring 261 to protect the spring 261, and the two ends of the telescopic rod 267 are respectively fixedly connected to the support block 19 and the vibration block 25; the gear 262 is rotatably set on the belt, and the rack 263 is vertically fixed to the side wall of the square tube welded plate 83, and the gear 262 is meshed with the rack 263.

[0076] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the connecting tube 264 is horizontally arranged and rotatably connected to the top of the support block 19. The cam 265 is arranged between the vibrating block 25 and the support block 19 and is sleeved and fixed on the connecting tube 264. One end of the rotating rod 266 is fixedly set on the gear 262, and the other end of the rotating rod 266 is inserted into the connecting tube 264. A guide block 268 is fixedly set on the side wall of the rotating rod 266, and a guide groove 269 is opened along the inner wall of the connecting tube 264 along its axial direction for the guide block 268 to slide.

[0077] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the staff first places the rotor punching on the vibration block 25. When the belt drives the support block 19 to move in the vertical direction, the rack 263 can drive the gear 262 to rotate, the gear 262 drives the rotating rod 266 to rotate, the rotating rod 266 drives the guide block 268 to rotate, the guide block 268 can drive the connecting pipe 264 to rotate, the connecting pipe drives the cam 265 to rotate, and the side wall of the cam 265 can drive the vibration block 25 to move back and forth in the vertical direction. The spring 261 is continuously stretched, and the vibration block 25 continuously vibrates the rotor punching, thereby further reducing the difficulty of lowering the rotor punching.

[0078] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, a clamping block 27 is provided on the top of the vibration block 25, and a guide plate 28 is fixedly connected to the top of the vibration block 25. The clamping plate is horizontally penetrated and slides on the guide plate 28. A slope is provided on the top of the clamping block 27. The clamping block 27 slides on the slope to fit the bottom side wall of the rotor punching. The clamping block 27 abuts against the top of the rotor punching. A pushing member 2 for pushing the clamping block 27 to move is provided on the vibration block 25. The pushing member 2 is a pushing spring 29. The two ends of the pushing spring 29 are respectively fixed on the guide plate 28 and the abutting block 211; a guard rod 2 30 is provided inside the pushing spring 29. One end of the guard rod 30 is fixed on the guide plate 28, and the clamping block 27 slides on the guard rod 2 30.

[0079] like Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, when the staff places the rotor punching on the vibration block 1 25, the gravity of the rotor punching can push the clamping block 27 to move through the inclined surface on the clamping block 27, and the pushing spring 29 is stretched. When the rotor punching abuts against the vibration block 1 25, the elastic force of the pushing spring 29 can push the clamping block 27 to move to the upper position of the rotor punching, thereby clamping the rotor punching, and then the rotor punching can move downward with the support block 19, further reducing the difficulty of the rotor punching to descend.

[0080] like Figure 3 、 Figure 9 and Figure 10 As shown, there are two auxiliary positioning wedge keys 31 for positioning the rotor core that slide horizontally on the laminated base plate. The auxiliary positioning wedge keys 31 can be inserted into the grooves on the side walls of the rotor core. Two groups of moving components 32 are also provided on the laminated base plate.

[0082] like Figure 3 、 Figure 9 and Figure 10 As shown, before the positioning ruler 8 moves toward the direction close to the rotor punching, the secondary positioning wedge key 31 is located away from the rotor punching. When the positioning ruler 8 moves toward the direction close to the rotor punching, it can drive the driving rod 321 to move, and the driving rod 321 can drive the connecting rod 324 to rotate. The connecting rod 324 can drive the slide plate and the secondary positioning wedge key 31 to move toward the rotor punching at the same time until the secondary positioning wedge key 31 is inserted into the groove on the edge of the rotor punching, thereby further improving the coaxiality and accuracy of the rotor core slot, and further improving the verticality of the rotor core.

A threaded sleeve 375 is welded and fixed to the inner wall of the second connecting pipe 372. The threaded rod 371 is threadedly matched with the threaded sleeve 375. The connecting pipe A reset member is provided in the second 372 to reset the threaded rod 371. The reset member is a reset spring 376. The reset spring 376 is vertically arranged, and the two ends of the reset spring 376 respectively abut against the bottom end of the threaded rod 371 and the inner wall of the bottom end of the connecting pipe 372; a rotating plate 377 is rotatably provided at the bottom of the slide plate, and the rotating plate 377 is fixedly connected to the bottom end of the connecting pipe 372; a top block 378 is fixedly provided on the top of the rotating plate 377, and the top block 378 is provided with an arc surface. The top block 378 is fitted with the push block 34 through the sliding of the arc surface.

[0085] like Figure 3 、 Figure 9 and Figure 10 As shown, when the rotor punching is completed, the rotor upper base plate 10 can be driven to move downward. During the downward movement of the rotor upper base plate 10, the threaded rod 371 can be driven to move downward. The threaded rod 371 can drive the threaded sleeve 375 to rotate. The threaded sleeve 375 can drive the connecting pipe to rotate. The connecting pipe can drive the rotating plate 377 to rotate. The rotating plate 377 can drive the top block 378 to rotate. The top block 378 can continuously push the push block 34 to compress the spring 35 through the arc surface to move. The push block 34 continuously drives the vibration block 2 33 to stretch the spring 4 36 to move. The vibration block 2 33 can continuously abut against the rotor The lower base plate 6 can vibrate the rotor lower base plate 6, thereby making the various punching sheets of the rotor core fit closely together, reducing the gaps between the punching sheets, improving the rigidity and mechanical strength of the rotor, and helping the punching sheets to achieve better contact before welding, thereby improving the quality and consistency of welding; at the same time, it can partially release the internal stress generated in the core, reducing the risk of deformation or damage to the rotor during use; when the secondary positioning wedge key 31 is away from the rotor core, the reset member provided can make the threaded rod 371 move to the initial position, so as to facilitate the next drive of the rotor lower base plate 6 to vibrate.
