[0070] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0071] The utility model of the waste motor dismantling machine first designs a waste motor dismantling mother machine 1, and its overall structure is as follows Figure 1As 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 tooling, so a plurality of mounting holes 121 are provided on the operating table 12 for positioning and fixing the tooling, 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 (i.e., a vertical drive mechanism) is provided on the top of the frame 11, and a horizontal cylinder 14 (i.e., a horizontal drive mechanism) 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.

[0072] like Figure 2 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 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.

[0073] When the tooling for breaking the rear cover is installed on the mother machine 1 for disassembling the waste motor for use, the waste motor to be disassembled is placed as a whole in the V-shaped groove of the lower V-shaped clamp block 22 on the lower clamp bracket 21 for breaking the cover on the operating table 12, so that the motor output shaft of the waste motor faces the push head 25 installed on the piston rod end 141 of the horizontal oil cylinder 14, and the height of the lower clamp bracket 21 for breaking the cover is adjusted to make the motor output shaft and the push head 25 have the same height and be as coaxial as possible; then, the vertical oil cylinder 13 works to drive the upper clamp bracket for breaking the cover 23 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 to push the push head 25 to the end of the motor shaft, and 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 of the motor, thereby realizing the separation of the stator housing assembly and the rotor shaft assembly.

[0074] Further, if Figure 3 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, so as to adjust the length of the V-shaped groove of the lower V-shaped clamp block 22 where the power supply is placed as a whole, and wrap the length of the entire 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 motor housing.

[0075] Further, if Figure 4 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.

[0076] like Figure 5 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.

[0077] After separating the rotor and the shaft, the stator and the casing assembly need to be separated. Figure 6 , Figure 7 As 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.

[0078] 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 is positioned through 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; at this time, the stator pressing sleeve 32 is located directly below the vertical cylinder 13 and the stator pressure head 33; the vertical cylinder 13 is started, so that the stator pressure 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, 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.

[0079] 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.

[0080] As a further improvement of the present invention, it is also possible to Figure 2 The waste motor with broken back cover tooling shown is disassembled into the mother machine 1 for upgrading, such as Figure 8-Figure 11 As shown, opposite to the horizontal oil cylinder 14, another horizontal oil cylinder is arranged, namely, the horizontal stator removal oil cylinder 15, and a stator top tool 26 is installed on its piston rod. The diameter of the stator top tool 26 is smaller than the inner diameter of the motor housing and matches the size of the stator core; preferably, the horizontal oil cylinder 14 and the horizontal stator removal oil cylinder 15 are located on the same horizontal axis. Thus, a rotor and stator integrated machine is formed in a waste motor disassembly mother machine 1.

[0081] 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 from the waste motor, so as to realize the separation of the stator housing assembly and the rotor shaft assembly. 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Preferably, two vertical motion guides 27 are provided, symmetrically arranged on both sides of the V-shaped clamping block 24 .

[0087] As a further improvement of the present invention, Figure 2 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 which is thin at the front and thick at the back, thereby forming an integrated machine for removing the rotor and stator. 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 further separate the stator assembly.

[0088] As a further improvement of the present invention, Figure 2 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, thereby forming an integrated machine for removing the rotor and stator. 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.

[0089] The separated rotor and shaft need to be further separated. Fig.11 , Fig.12As shown, a shaft removal tool is installed on the waste motor disassembly mother machine 1, forming the third step of disassembling the waste motor, and 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 122 is intersected; 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. , forming 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 recessed 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.

[0090] 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.

[0091] 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.14 , Fig.15 , Fig.16 As shown, a stator pressing and cutting tool is installed on the waste motor disassembly mother machine 1, forming the fourth step of disassembling the waste motor, and 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 the second step of disassembling the waste motor 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 in the center, so that the knife groove 52 is located in the middle of the stator assembly Position; a cutting blade 53 is installed at the bottom of the piston rod 131 of the vertical cylinder 13, and the cutting blade 53 is located directly above the knife groove 52 and matches the knife groove 53; the vertical cylinder 13 works, driving the piston rod 131 to extend downward, that is, driving the cutting blade 53 to move vertically downward, that is, constantly contacting 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.

[0092] 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 disassembly 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 deflecting.
