Description

Technical Field

[0001] The invention relates to a special machine for dismantling waste motors, belonging to the technical field of waste dismantling and recycling. Background Art

[0002] When recycling old motors, the motors need to be fully disassembled, such as opening the end cover of the casing, removing the rotor assembly, separating the shaft, removing the stator assembly, and separating the copper wire windings, so as to achieve classified recycling and reuse of different waste materials and different metal types.

[0003] At present, in the dismantling of scrap motors, especially the dismantling of rotor assemblies and stator assemblies, the traditional manual hammering and cutting methods are still used. The dismantling process is scattered, time-consuming and labor-intensive, and there are hidden dangers to operational safety.

[0004] Most of the dismantling equipment on the market is only for dismantling the copper wire winding of the stator assembly, and rarely involves the full process dismantling of the entire motor. Therefore, it is necessary to carry out special design for the full process dismantling of waste motors, so that the dismantling process of waste motors can be systematized, thereby reducing the labor intensity of dismantling, improving the safety of the dismantling process, and then improving the dismantling efficiency. Summary of the invention

[0154] The waste motor disassembly system of the present invention combines the structure of the AC motor to design a waste motor disassembly process and equipment, thereby enabling efficient disassembly of the waste motor:

[0155] Step 1: Use press 1 in combination with a clamp to fix the casing of the used motor; use press 2 in combination with a pusher to apply pressure from the protruding end of the shaft of the used motor to push the shaft of the used motor together with the rotor core out of the used motor; during the process, the end covers connected at both ends of the casing are directly broken.

[0156] In the above step 1, if the casing of the scrap motor is thin, or the stator core is firmly combined with the casing, the stator core will be fixed at the same time as the casing is fixed, so a thinner ejector is used to eject only the rotor core together with the shaft from the motor; at this time, an additional three-in-one press tool is required to eject the stator core from the casing;

[0157] If the casing of the scrap motor is thicker and stronger, such as an iron casing, and the stator core is not firmly combined with the casing, the stator core will be subject to a smaller clamping force when the casing is fixed, and a thicker ejector can be used to eject the stator core from the casing together with the rotor core together with the rotating shaft from the motor; the process of ejecting the stator core horizontally can use the same set of ejectors or different ejectors; when different ejectors are used, two sets of horizontal presses can be provided accordingly, that is, a press three is provided opposite to the press two.

[0158] Step 2: Use a press and a four-combination ejector to eject the shaft from the rotor core; the shaft is generally made of better steel and can be recycled separately;

[0159] Step 3: Use the press five combined with the cutter to cut the stator core in half from the middle, so that the enameled wire embedded in the stator core is broken open, which is convenient for subsequent disassembly and recycling;

[0160] Step 4: Use the enameled wire disassembly equipment to pull the enameled wire out of the stator core, so that the enameled wire is separated from the stator core to achieve material classification and recycling.

[0161] In combination with the waste motor disassembly system of the above invention, the present invention also provides a waste motor disassembly device, such as Figure 1 shown.

[0162] The waste motor disassembly system of the present invention comprises step 0, taking the waste motor to be disassembled.

[0163] A rear cover breaking device A is provided for processing step 1; preferably, the waste motor to be disassembled is placed horizontally on the lower clamp, the first press exerts downward force to drive the upper clamp to clamp the casing, and then the second press presses the shaft horizontally, and the rear cover is broken through the shaft and the rotor assembly; at the same time, the front cover is also crushed.

[0164] During the process, if the stator assembly is not ejected, the housing and the stator assembly need to be removed and placed in the stator removal device B. The press three applies downward pressure to separate the stator assembly from the housing.

[0165] Alternatively, in the rear cover breaking device A, when the casing is clamped by the clamp by the action of the press one, when the casing of the scrap motor is thicker and stronger, and the stator core is not firmly combined with the casing, the stator core is horizontally pressed by the press two or the press three in combination with the pushing tool to push the stator core out of the casing.

[0166] A shaft removal device C is provided for processing step 2; preferably, the rotor and shaft assembly are placed vertically, the bottom of the rotor is supported, and the press four combined with the top tool press downward from the top of the shaft to push the shaft out of the rotor core; the shaft and the rotor core are separated.

[0167] A stator pressing and cutting device D is provided for processing step 3; preferably, the stator assembly is horizontally placed on a fixed seat, a cutter clearance space is provided in the middle of the fixed seat, and the presser 5 drives the cutter to press down and cut from the middle of the stator core. Since the stator core is composed of a plurality of stator silicon steel sheets (the number ranges from dozens to hundreds) stacked together, it is easy to be cut by the cutter; while the cutter separates the stator core, the enameled wire embedded in the stator slot of the stator core is cut off, thereby dividing the stator assembly as a whole into two.

[0168] An enameled wire winding disassembly device E is provided for processing step 4; preferably, the stator core and enameled wire winding assembly cut off in step 3 are placed horizontally, the assembly of the stator core and the enameled wire winding is fixed, and then the end of the enameled wire winding is hooked by the claw mechanism in the enameled wire winding disassembly device E, and the cut enameled wire winding is pulled out from the stator slot of the stator core in combination with the horizontal motion mechanism; the enameled wire winding can be pulled out group by group, or multiple groups can be pulled out together for a whole week, so that the enameled wire is separated from the stator core, and the material classification and recycling are realized.

[0169] For steps 1 to 3, which are mainly press operations, a universal waste motor disassembly machine 1 is designed, and its overall structure is as follows: Figure 2 As shown, it includes a frame 11, which is a vertical frame with a rectangular hollow operating space in the middle; an operating table 12 is provided at the lower part of the frame 11 for installing different fixtures, so a plurality of mounting holes 121 are provided on the operating table 12 for positioning and fixing the fixtures, and a through hole 122 is also provided in the middle of the operating table 12 to facilitate the passage of long-axis parts; a vertical cylinder 13 is provided on the top of the frame 11, and a horizontal cylinder 14 is provided on the side of the frame 11, and the piston rod end 141 of the vertical cylinder 13 and the piston rod end 141 of the horizontal cylinder 14 are both located in the operating space in the middle of the frame 11, and different extrusion operation functions can be realized by assembling different components.

[0170] like Figure 3 As shown, a tool for breaking the rear cover is installed on a mother machine 1 for dismantling a waste motor, forming the first step of dismantling the waste motor, breaking the rear cover, and separating the stator and the rotor; a lower clamp bracket 21 for breaking the cover is installed on the operating table 12, on which a plurality of groups of lower V-shaped clamps 22 are installed; an upper clamp bracket 23 for breaking the cover is installed at the piston rod end of the vertical oil cylinder 13, on which a plurality of groups of upper V-shaped clamps 24 are installed; the central axis of the V-shaped groove formed by the lower V-shaped clamp 22 and the upper V-shaped clamp 24 is parallel to the axis of the horizontal oil cylinder 14; a push head 25 is installed at the piston rod end 141 of the horizontal oil cylinder 14.

[0171] When the broken rear cover tooling is installed on the waste motor disassembly mother machine 1 for use, the waste motor to be disassembled is placed as a whole in the V-shaped groove of the V-shaped clamp block 22 under the broken cover lower clamp bracket 21 on the operating table 12, so that the motor output shaft of the waste motor faces the push head 25 installed at the piston rod end 141 of the horizontal oil cylinder 14, and the motor output shaft and the push head 25 are made to be at the same height and as coaxial as possible by adjusting the height of the broken cover lower clamp bracket 21; then, the vertical oil cylinder 13 works, and the piston rod extends vertically downward, driving the broken cover upper clamp bracket 2 3 and the upper V-shaped clamp block 24 are pressed down, so that the V-shaped groove of the upper V-shaped clamp block 24 is pressed on the top of the waste motor, and cooperates with the lower V-shaped clamp block 22 to fix the waste motor to be disassembled as a whole in the frame 11; finally, the horizontal cylinder 14 works, the piston rod extends horizontally, and the push head 25 is pushed toward the end of the motor shaft. By applying pressure to the end of the motor shaft, the other end of the motor shaft pushes the motor end cover, and the motor shaft is connected to the motor rotor and the rear end cover and is pushed out from the waste motor, thereby realizing the separation of the stator housing assembly and the rotor shaft assembly.

[0172] Further, if Figure 4 As shown, the lower V-shaped clamp block 22 is a narrow block, and the number of the lower V-shaped clamp blocks 22 can be increased according to the length of the motor housing, thereby adjusting the length of the V-shaped groove of the lower V-shaped clamp block 22 in which the power supply unit is placed as a whole, so that the V-shaped groove can wrap the entire length of the motor housing as much as possible. Furthermore, a plurality of anti-slip teeth 221 are provided on the lower V-shaped clamp block 22 along the axial direction of the V-shaped groove, so that after being subjected to force, the lower V-shaped clamp block 22 is embedded in the motor housing and fully holds the waste motor housing.

[0173] Further, if Figure 5 As shown, the upper V-shaped clamp block 24 is a plate-shaped clamp block, which is provided with several blocks and is fixed on both sides of the upper clamp bracket 23 of the broken cover by the cooperation of screws 242 and nuts. The upper V-shaped clamp blocks 24 located on both sides of the upper clamp bracket 23 of the broken cover are as symmetrical as possible, so that the force applied by the vertical cylinder 13 is uniform when working; the upper V-shaped clamp block 24 is provided with several anti-slip teeth 241 perpendicular to the axial direction of the V-shaped groove, which also play the role of being embedded in the motor housing after being subjected to force and fully clamping the motor housing, but is limited by the thickness of the upper V-shaped clamp block 24, so it is opened along the groove wall of the V-shaped groove.

[0174] like Figure 6 As shown, the upper V-shaped clamp block 24 is a movable herringbone clamp, and a mounting ear 231 is provided below the upper clamp bracket 23 of the broken cover. The upper V-shaped clamp block 24 is provided with a mounting block 243. The mounting ear 231 and the mounting block 243 are connected together by a pin shaft 232, so that the angle of the upper V-shaped clamp block 24 can be adjusted to adapt to motor housings of different shapes.

[0175] After separating the rotor and the shaft, the stator and the casing assembly need to be separated. Figure 7 , Figure 8As shown, a stator removal tool is installed on the waste motor disassembly mother machine 1 to form the second step of disassembling the waste motor, and the stator is separated from the casing; a stator removal support 31 is installed on the operating table 12, and the lower part of the stator support 31 is hollowed out to form a stator accommodating cavity 311, and a casing positioning flange 312 is installed in the middle of the upper part of the stator support 31, and a through hole is provided in the middle of the casing positioning flange 312 for the stator to pass through without obstacle, and the through hole is connected with the stator accommodating cavity 311; the stator to be separated is placed on the operating table 12, and the stator is placed on the operating table 12. The separated stator housing assembly 30 is placed on the stator support 31 and positioned by the housing positioning flange 312, so that the wall of the housing is above the housing positioning flange 312 to form a support, and the stator is completely located in the through hole area of ​​the housing positioning flange 312; then a stator pressing sleeve 32 is placed above the stator, and the stator pressing sleeve 32 is in contact with the stator core; a stator pressing head 33 is installed at the piston rod end of the vertical oil cylinder 13, and the stator pressing head 33 matches the stator pressing sleeve 32.

[0176] When the stator removal tool is installed on the waste motor disassembly mother machine 1 for use, the stator housing assembly 30 to be separated is placed on the stator removal support 31 and positioned by the housing positioning flange 312; then the stator pressing sleeve 32 is placed on the top of the stator, and the stator pressing sleeve 32 is in contact with the stator core; at this time, the stator pressing sleeve 32 is located directly below the vertical cylinder 13 and the stator pressing head 33; the vertical cylinder 13 is started, so that the stator pressing head 33 is in contact with the stator pressing sleeve 32, and the stator pressing sleeve 32 is pressurized, and the stator pressing sleeve 32 pushes the stator core downward, and the stator core connected to the coil passes through the through hole of the housing positioning flange 312 and gradually falls into the stator accommodating cavity 311 of the stator removal support 31.

[0177] A flange 321 may be provided at the top of the stator sleeve 32, and the outer diameter of the flange is larger than the inner diameter of the casing; and the lower length of the stator sleeve 32 is longer than the engagement distance of the stator core in the casing; in this way, when the stator sleeve 32 completely squeezes the stator assembly out of the casing, the stator sleeve 32 loses resistance and falls on the casing, and will not fall into the stator accommodating cavity 311 together with the core, causing a risk of falling.

[0178] As a further improvement of the present invention, it is also possible to Figure 3 The waste motor with broken back cover tooling shown is disassembled into the mother machine 1 for upgrading, such as Figure 9-12 As shown, opposite to the horizontal cylinder 14, another horizontal cylinder is arranged, namely, the horizontal stator removal cylinder 15, on whose piston rod is mounted a stator top tool 26, the diameter of which is smaller than the inner diameter of the motor housing and matches the size of the stator core; preferably, the horizontal cylinder 14 and the horizontal stator removal cylinder 15 are located on the same horizontal axis.

[0179] During operation, the waste motor to be disassembled is first fixed as a whole by the vertical cylinder 13; then, the horizontal cylinder 14 works, and the push head 25 pushes against the end of the motor shaft, and by applying pressure to the end of the motor shaft, the other end pushes the motor end cover, and the motor shaft is connected to the motor rotor and the rear end cover and is pushed out from the waste motor, so that the stator housing assembly and the rotor shaft assembly are separated. At this time, the motor rotor and the rear end cover fall on the side close to the horizontal stator disassembly cylinder 15; finally, the horizontal stator disassembly cylinder 15 is started, and the piston rod extends, driving the stator top tool 26 to extend, horizontally push against the stator core, and push the stator core gradually away from the motor housing. In the process, the broken front end cover on the motor housing will be driven to fall together, and the stator core and the front end cover will fall on the side close to the horizontal cylinder 14.

[0180] That is, through the above improvement, the motor rotor, stator core, end cover and motor housing can be separated at the same time when the waste motor is clamped horizontally.

[0181] However, due to the addition of the horizontal stator dismantling cylinder 15, the stator top tool 26, etc., the frame 11 needs to be widened.

[0182] At the same time, in order to improve the reliability and stability of the vertical cylinder 13 driving the upper V-shaped clamp 24 to press downward, a vertical movement guide 27 is preferably provided between the upper V-shaped clamp 24 and the frame 11.

[0183] The vertical motion guide 27 includes a connecting rod 271, a slider 272, and a slide rail 273; the V-shaped clamp block 24, or the clamp bracket 23 on the broken cover is connected to the slider 272 through the connecting rod 271; the slide rail 273 is vertically fixed on the inner side of the frame 11; the slider 272 is connected to the slide rail 273 to form a vertical motion guide mechanism.

[0184] Preferably, two vertical motion guides 27 are provided, symmetrically arranged on both sides of the V-shaped clamping block 24 .

[0185] As a further improvement of the present invention, Figure 3 The push head 25 installed at the piston rod end 141 of the middle horizontal oil cylinder 14 is replaced with a stepped push head with a thin front and a thick back. The thin push head first pushes the rotating shaft to separate the rotor assembly, and then the push head 25 continues to extend, and the thick push head pushes the stator assembly to separate the stator assembly again.

[0186] As a further improvement of the present invention, Figure 3 The push head 25 installed at the piston rod end 141 of the middle horizontal oil cylinder 14 is replaced with a rough push head adapted to the stator assembly. The rough push head first contacts the rotating shaft to separate the rotor assembly, and then the push head 25 continues to extend and contacts the stator assembly to separate the stator assembly again.

[0187] The separated rotor and shaft assembly needs to be further separated from the rotor and shaft. Fig.13 , Fig.14 As shown, a shaft removal tool is installed on the waste motor disassembly mother machine 1, corresponding to step 2 of the waste motor disassembly, the rotor and the shaft are separated; a shaft removal positioning plate 41 is installed on the operating table 12, and a shaft through hole 411 is provided in the middle of the shaft removal positioning plate 41 for the shaft to pass through without obstacle, and the shaft through hole 411 is connected with the through hole 122 on the operating table 12; the rotor shaft assembly to be separated is placed on the shaft removal positioning plate 41, that is, the bottom of the shaft 402 of the rotor shaft assembly that exceeds the rotor 401 is inserted into the shaft through hole 411, and the rotor 401 is placed on the rotor positioning plate 41. 1 to form a support; then put the rotor pressing sleeve shaft 42 on the top of the rotating shaft 402, the main body diameter of the rotor pressing sleeve shaft 42 is smaller than the inner diameter of the rotor 401, the bottom of the rotor pressing sleeve shaft 42 is preferably provided with a concave hole 421, which can be sleeved on the upper part of the rotating shaft 402 to achieve vertical positioning, and the top of the rotor pressing sleeve shaft 42 is preferably provided with a flange 422, whose diameter is larger than the inner diameter of the rotor 401, and by increasing the area, it is better in contact with the rotating shaft pressure head 43; a rotating shaft pressure head 43 is installed at the piston rod end of the vertical oil cylinder 13, and the rotating shaft pressure head 43 matches the rotor pressing sleeve shaft 42.

[0188] When the shaft removal tooling is installed on the waste motor disassembly mother machine 1 for use, the rotor shaft assembly to be separated is placed on the shaft removal positioning plate 41 and positioned through the shaft through hole 411, so that the rotor 401 is on the rotor positioning plate 41 to form a support, and the bottom of the shaft 402 is inserted into the shaft through hole 411 and extends into the through hole 122, and the shaft 402 is completely located in the area of ​​the shaft through hole 411 and the through hole 122; then, a rotor pressing shaft 42 is placed above the shaft 402, and rotor pressing shafts 42 of different lengths are selected according to the size specifications of the shaft 402, which can reduce the output of the vertical oil cylinder 13. Idle stroke; the concave hole 421 of the rotor pressing sleeve shaft 42 contacts and cooperates with the top of the rotating shaft 402; at this time, the rotor pressing sleeve shaft 42 and the rotating shaft 402 are located directly below the vertical cylinder 13 and the rotating shaft pressure head 43; the vertical cylinder 13 is started, so that the rotating shaft pressure head 43 contacts the rotor pressing sleeve shaft 42, and pressure is applied to the rotor pressing sleeve shaft 42. The rotor pressing sleeve shaft 42 pushes the rotating shaft 402, and the rotating shaft 402 passes through the rotating shaft through hole 411, and gradually separates from the rotor 401. The rotating shaft 402 passes through the through hole 122, and finally falls to the bottom of the operating table 12 for recovery, while the rotor 401 remains on the rotating shaft positioning plate 41. When the rotating shaft 402 withdraws from the rotor 401, the rotor pressing sleeve shaft 42 loses resistance and falls freely, and the lower part also penetrates into the inner hole of the rotor 401, but is limited by the flange 422, and the flange 422 falls on the rotor 401, which is convenient for recovering the rotor pressing sleeve shaft 42 for reuse.

[0189] The stator assembly separated by the stator tooling has copper enameled wire wound on the stator core. The enameled wire needs to be separated from the stator core. The separation process firstly separates the stator assembly connected to the enameled wire winding into two parts, disconnects the two ends of the enameled wire winding, and then uses special tools or equipment to pull out the enameled wire winding part remaining in the stator core from the stator core. Fig.15 , Fig.16 , Fig.17 As shown, a stator pressing and cutting tool is installed on the scrap motor disassembly mother machine 1, corresponding to step 3 of the scrap motor disassembly, the stator core and the copper enameled wire winding are cut off to facilitate the subsequent metal classification and recycling; a stator fixing seat 51 is installed on the operating table 12, and the stator fixing seat 51 is a V-shaped seat. The stator assembly withdrawn in step 1 of the scrap motor disassembly can be placed flat in the V-shaped seat of the stator fixing seat 51; a knife groove 52 is provided in the middle of the stator fixing seat 51, and the stator assembly is placed on the stator fixing seat 51, so that the knife groove 52 is located in the middle of the stator assembly A cutting blade 53 is installed at the bottom of the piston rod 131 of the vertical oil cylinder 13. The cutting blade 53 is located just above the knife groove 52 and matches the knife groove 53. The vertical oil cylinder 13 works to drive the piston rod 131 to extend downward, that is, to drive the cutting blade 53 to move vertically downward, that is, to continuously contact the middle part of the stator assembly located on the stator fixing seat 51 until the cutting blade 53 runs into the knife groove 52, and finally divides the stator assembly into two, forming two components with copper enameled wire windings, and the copper enameled wire windings are also divided into two.

[0190] As a further improvement of the present invention, since the stator assembly is small and heavy, the stator fixing seat 51 is designed to be shorter to facilitate the transportation of the stator assembly, but this results in a longer running distance of the driving piston rod 131 of the vertical cylinder 13. In order to ensure the pressing and cutting process, the pressing and cutting blade 53 maintains vertical operation, and the pressing and cutting blade 53 is connected to the bottom of the driving piston rod 131 through the blade fixing seat 54; a guide plate 55 is vertically installed on the inner side wall of the frame 11 of the waste motor dismantling machine 1, and a guide block 56 is provided on the blade fixing seat 54 extending in the direction of the guide plate 55, and the guide block 56 is matched with the guide plate 55, so that the blade fixing seat 54 can always move in the vertical direction, thereby allowing the pressing and cutting blade 53 to maintain vertical downward movement, cut off the stator assembly, and prevent the blade from shifting.

[0191] With respect to step 4, the structure of the enameled wire winding disassembly equipment E is further designed.

[0192] Embodiment 1 of the enameled wire winding disassembly device E is a double-claw device, which removes the enameled wire windings from the stator slots of the stator core one by one.

The lifting drive element 622 is vertically installed, and a plurality of vertical guide elements 623 (such as linear bearings and guide rods) are also vertically installed between the lifting platform 621 and the bottom plate of the frame 61. The lifting drive element 622 is operated to drive the lifting movement of the entire lifting platform 621.

[0194] A pair of rotatable rotating rollers 624 are installed on the lifting platform 621 through a bracket 625.

When the rotating driving element 626 works, it outputs a rotating driving force, which is transmitted through the rotating driving assembly 627, and finally drives one or two rotating rollers 624 to rotate, and then drives the stator assembly located thereon to rotate.

[0195] On the side of the lifting platform 621 close to the clamping mechanism 63, a stator retaining frame 628 is provided, in which a plurality of stator blocks 629 are arranged. The stator blocks 629 are horizontally installed in the stator retaining frame 628, and the inner ends of the stator blocks 629 form retaining claws 6291. The position of the stator blocks 629 in the stator retaining frame 628 can be adjusted according to the diameter of the stator assembly, so that the retaining claws 6291 are against the stator core and the ends of the enameled wire windings are exposed. The stator retaining frame 628 and the stator blocks 629 are arranged on both sides of the stator assembly, and cooperate with the rotating roller 624 to expose the upper and lower spaces of the stator assembly, so that the clamping mechanism 3 can be extended to hook the ends of the enameled wire windings.

[0196] The stator retainer 628 is provided with a fixing screw 6292, which can fix the stator stopper 629 in the stator retainer 628 to prevent the stator stopper 629 from being moved during the subsequent rotation of the stator assembly, resulting in blocking failure.

There are two clamping jaw driving elements 633, which are respectively located on the upper and lower sides of the head box 631 and are respectively connected to one clamping jaw 632; the two clamping jaw driving elements 633 are actuated at the same time, and the driving piston rod 6333 is extended at the same time, so that the driving end 6323 of the clamping jaw 632 is driven to move inward relatively, thereby driving the grab hook 6321 to move inward relatively, thereby clamping the end of the enameled wire winding, otherwise it is released.

[0198] A translation drive head 634 is also provided in the head box 631 and is connected to the feeding mechanism 64 .

[0199] The overall structure of the feeding mechanism 64 is as follows: Fig.21 As shown, it includes a feed drive element 641, which is a hydraulic cylinder. The tail of the cylinder body 6411 is hinged to the support seat 642 through a hinge 643, and the support seat 642 is fixed to the frame 61; the piston rod 6412 of the feed drive element 641 is connected to the translation drive head 634 of the clamping claw mechanism 63. Below the cylinder body 6411, there is also a bracket 644, which is in contact with the cylinder body 6411 but not fixed, and provides support for the cylinder body 6411.

The piston rod 6333 of the clamping jaw driving element 633 is in a retracted state, and the clamping jaw 632 is fully opened; the feeding driving element 641 of the feeding mechanism 64 is started, and its piston rod 6412 is extended, pushing the clamping jaw mechanism 63 to approach the lifting mechanism 62 under the guidance of the slide rail 651 and the slider 652, especially making the hook 6321 of the clamping jaw 632 located at the upper and lower sides of the enameled wire winding of the stator assembly;

At this time, the catch hook 6321 hooks the enameled wire winding away from the stator assembly, and pulls the enameled wire winding out of the stator assembly;

[0207] 2.4. Start the clamp driving element 633 to retract the piston rod 6333 and drive the clamp 632 to open outward, so that the enameled wire winding hooked on the hook 6321 falls down due to gravity and is recovered; thereby completing the pulling and disassembly work of one or two groups of enameled wire windings in the stator assembly;

[0208] 2.5. Start the rotating drive element 626 to drive the rotating roller 624 to rotate, thereby driving the stator assembly to rotate a certain angle, and rotating the enameled wire winding still remaining on the stator assembly to the upper and lower positions;

[0209] 2.6. Repeat steps 2.1 to 2.5 until all the enameled wire windings on the stator assembly are pulled out, leaving only the stator core, thus completing the special disassembly of the enameled wire windings of a scrap motor stator assembly.

[0210] Embodiment 2 of the enameled wire winding disassembly device E is a multi-claw device that can remove all enameled wire windings from the stator slots of the stator core at one time, such as an eight-claw enameled wire winding disassembly device, and the overall structure is as follows: Fig. 22As shown, it includes a main frame 71, on which a clamping mechanism 72 and a copper pulling mechanism 73 are arranged in a horizontal direction; the clamping mechanism 72 is fixed to one end of the main frame 71; the bottom workbench of the copper pulling mechanism 73 is horizontally installed on the main frame 71 through the cooperation of a slide rail 751 and a slider 752, and can move horizontally; a copper pulling drive 74 is provided between the clamping mechanism 72 and the copper pulling mechanism 73, and the copper pulling drive 74 is a linear drive, which can drive the copper pulling mechanism 73 to move in a horizontal direction, approaching or moving away from the clamping mechanism 72.

[0211] The overall structure of the clamping mechanism 72 is as follows: Fig.23 As shown, it includes a clamping seat 721, on which a plurality of clamping claws 723 are provided, the clamping claws 723 are located inside the clamping seat 721, and the plurality of clamping claws are surrounded together to form a clamping space 722 for clamping the stator assembly; the clamping claws 723 are installed on the clamping seat 721 through a clamping drive element 724. In this embodiment, three clamping claws 723 are provided to form a three-claw clamping mechanism, and the clamping drive element 724 is a linear drive element, such as a hydraulic cylinder, the cylinder body of which is fixed on the clamping seat 721, and the clamping claws 723 are installed inwardly on the top of the piston rod. Preferably, the clamping claws 723 are arc-shaped claws, which can increase the contact area with the outer surface of the stator assembly.

[0212] Furthermore, the clamping claw 723 is connected to a guide mechanism, which includes a guide plate 725 and a guide device 726. The guide plate 725 is connected to the bottom of the clamping claw 723, and the other end of the guide plate 725 is connected to the guide device 726. The guide device 726 is a linear guide device, such as a guide cylinder, whose cylinder body is fixed on the clamping seat 721, and the end of the extended guide rod 7261 is fixed to the guide plate 725. By setting a guide mechanism and cooperating with the clamping drive element 724, the clamping claw 723 can only have a linear motion along the clamping drive element 724 without deflection, so that the arc of the clamping claw 723 can always be set along the arc of the clamping space 722.

[0213] The clamping mechanism 72 is also provided with a copper extraction drive connecting plate 727 , preferably two of which are provided, one on each side of the clamping mechanism 72 .

[0214] The overall structure diagram of the combined state of the copper pulling mechanism 73 and the copper pulling drive 74 is as follows Fig.24 shown.

[0215] The copper pulling mechanism 73 includes a slide plate 730, a slider 752 is installed under the slide plate 730, and a slide rail 751 is horizontally arranged on the main frame 71; the slider 752 and the slide rail 751 are respectively located on both sides of the slide plate 730 and the main frame 71, so that the slide plate 730 can move horizontally relative to the main frame 71. The copper pulling drive 74 is a linear drive, and is provided with a linear drive element, such as a hydraulic cylinder. Preferably, there are two linear drive elements, which are respectively located on both sides of the slide plate 730; the cylinder body 741 of the linear drive element of the copper pulling drive 74 is connected to the clamping seat 721 of the clamping mechanism 72 through the copper pulling drive connecting plate 727; the piston rod 742 of the linear drive element of the copper pulling drive 74 is connected to the slide plate 730 through the connecting seat 743; preferably, both ends of the linear drive element of the copper pulling drive 74 are hinged, which can reduce the installation accuracy requirements and eliminate assembly gaps and errors. The piston rod 742 of the linear drive element of the copper pulling drive 74 extends, that is, the driving slide 730 drives the entire copper pulling mechanism 73 away from the clamping mechanism 72; the piston rod 742 of the linear drive element of the copper pulling drive 74 contracts, that is, the driving slide 730 drives the entire copper pulling mechanism 73 close to the clamping mechanism 72.

[0216] The main body of the copper pulling mechanism 73 is mounted on the slide plate 730 of the copper pulling mechanism 73, and its internal structure is as follows: Fig.25 As shown, it includes a plurality of claws 731 distributed in an annular manner. In the present invention, eight claws 731 are arranged in one circle. Generally, the AC asynchronous motor is a 2-pole, 4-pole, or 6-pole motor, and is further equipped with a single-phase motor or a three-phase motor. By using eight claws 731, the ends of all enameled wire windings can be basically grasped at the same time. The root of the claw 731 is hingedly arranged on the claw seat 733 through a hinge shaft 7312, and a reset spring 7313 is arranged between the middle part of the claw 731 and the claw seat 733, and a pressing sleeve 732 is arranged on the outer side of the middle part of the claw 731. The pressing sleeve 732 is installed on the slide 730 or the claw seat 733 through the pressing claw driving element 735; the pressing claw driving element 735 is a linear driving element, such as a hydraulic cylinder, and the pressing claw driving element 735 is horizontally arranged, which can drive the pressing sleeve 732 away from the claw seat 733, that is, a plurality of claws 731 are gathered inward at the same time (the pressing sleeve 732 gathers the claws 731 inward), or drive the pressing sleeve 732 close to the claw seat 733, that is, a plurality of claws 731 are opened outward at the same time (the return spring 7313 always pushes the claws 731 outward). In this embodiment, the pressing claw driving element 735 is installed on the slide 730 through the mounting seat 736.

[0217] The end of the claw 731 is bent inward to form a hook 7311 , and the hook 7311 has a sharp end.

[0218] Preferably, a positioning boss 734 is further provided in the middle of the plurality of claws 731 .

[0219] When the eight-claw enameled wire winding removal equipment is working:

[0220] 1. Clamping stage; take the stator assembly of the enameled wire winding to be disassembled after being cut off in step 3; place the end of the enameled wire winding toward the copper pulling mechanism 73, and place the stator assembly horizontally in the clamping space 722 area of ​​the clamping mechanism 72;

[0221] The clamping driving element 724 of the clamping mechanism 72 is activated, so that the three clamping claws 723 are simultaneously retracted inwards to hold the stator assembly tightly, and the center position of the stator assembly is substantially located on the central axis of the clamping mechanism 72;

[0222] 2. Copper grabbing stage; the claws 731 of the copper pulling mechanism 73 are in an open state, that is, the circle formed by the inner tips of the hooks 7311 of the claws 731 is larger than the outer diameter of the end of the enameled wire winding on the stator assembly;

[0223] The copper pulling drive 74 is started, the piston rod 742 is contracted, and the copper pulling mechanism 73 is driven to move toward the clamping mechanism 72 until the hook 7311 of the claw 731 is located outside the end of the enameled wire winding of the stator assembly on the clamping mechanism 72;

[0224] At this time, the positioning boss in the middle of the copper pulling mechanism abuts against the center hole of the stator core of the stator assembly, and the center height of the stator core is corrected so that the distance between the outer circle of the end of the enameled wire winding and the grab hook of the claw is close or equal;

[0225] Then, the pressing claw driving element 735 is started to move the pressing sleeve 732 away from the claw seat 733, and the plurality of claws 731 are simultaneously gathered inward, and the grab hooks 7311 are simultaneously inserted into the end of the enameled wire winding to hook the enameled wire winding;

[0226] 3. Copper pulling stage: the copper pulling drive 74 is started, the piston rod 742 extends, and the copper pulling mechanism 73 is driven away from the clamping mechanism 72. At this time, the claw 731 and the hook 7311 pull out all the enameled wire windings on the stator assembly until all the enameled wire windings leave the stator assembly, and only the stator core remains on the clamping mechanism 72;

[0227] Then, the pressing claw driving element 735 is started, so that the pressing sleeve 732 is moved close to the claw seat 733, and the claws 731 are simultaneously opened outward, and the enameled wire windings carried by the claws 731 and the hooks 7311 fall down due to the gravity.

[0228] Finally, the clamping drive element 724 of the clamping mechanism 72 is activated, so that the three clamping claws 723 are opened outward at the same time to release the stator core, thereby completing the disassembly operation of the enameled wire winding of the stator assembly.

[0229] The above-mentioned enameled wire winding disassembly equipment E, the double-claw enameled wire winding disassembly equipment, and the eight-claw enameled wire winding disassembly equipment are all provided with a stator mounting platform on one side of the frame for placing or fixing the stator, and a claw structure driven by a linear drive element on the other side. The driving claw structure reaches the end of the enameled wire winding protruding outside the stator core, and the claw structure hooks the enameled wire winding, and then retreats to pull the enameled wire winding out of the stator core.

[0230] The double-claw enameled wire winding removal equipment is suitable for stator assemblies with relatively large stator assembly diameters, while the eight-claw enameled wire winding removal equipment is suitable for stator assemblies with relatively small stator assembly diameters.

[0231] The waste motor dismantling machine of the present invention realizes different processes of dismantling the waste motor by installing different tooling equipment on the waste motor dismantling mother machine 1, and the operation is convenient and safe. Finally, it is combined with the enameled wire winding dismantling equipment E to efficiently recover the copper coil, which greatly reduces the production cost and improves the production efficiency.
