[0002] With the development of science and technology, electric vehicles are being used more and more widely. Their practicality has brought great convenience and benefits to people. However, at the same time, the number of scrapped electric vehicles is also increasing day by day. If scrapped electric vehicles are not dismantled and recycled in time, it will not only cause waste of resources, but also have an impact on the ecological environment.

[0003] When recycling electric vehicles, the motor stator is crucial. The stator, or the motor core, consists primarily of spoke wheels, a central shaft, silicon steel discs, and copper wire windings. These windings typically consist of three groups, alternately wound in the slots of the silicon steel discs. To recycle the stator, the copper windings must be cut and then removed from the silicon steel laminations by extrusion or extraction, separating them for separate recycling.

[0004] In the prior art, the protruding part of the copper wire winding on the end face of the motor stator is generally cut off manually using an impact chisel or a grinding wheel, that is, the protruding part of the copper wire winding on the end face of the movement is chiseled off with a chisel or cut off with a grinding wheel. These two methods are not only time-consuming and labor-intensive, but also have low efficiency and great safety hazards. Utility Model Content

DETAILED DESCRIPTION

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1-5 As shown, a motor stator winding disassembly mechanism includes a stator fixing assembly, a cutting execution assembly and a positioning feed assembly, the stator fixing assembly includes a pneumatic chuck 11 for clamping the motor stator, and a circumferential feed motor 12 which is transmission-connected to the pneumatic chuck 11 and drives the motor stator to rotate; the cutting execution assembly is arranged side by side with the stator fixing assembly, the cutting execution assembly includes a saw blade 21, and a cutting motor 22 which drives the saw blade 21 to rotate; the positioning feed assembly can drive the cutting execution assembly to move in the axial direction and horizontal radial direction of the saw blade 21.

[0034] Among them, the stator fixing assembly is used to clamp and fix the motor stator, and at the same time drive the motor stator to rotate in the circumferential direction during the process of cutting the copper wire winding; the cutting execution assembly is used to cut the copper wire winding; the positioning feed assembly is used to move the position of the saw blade 21 so that it is in a suitable cutting position to ensure the accuracy and completeness of the copper wire winding cutting.

[0035] Specifically, the stator fixing assembly, the cutting execution assembly and the positioning and feeding assembly are all installed on a base plate 4 .

[0036] In order to fix the pneumatic chuck 11 and the circular feed motor 12 , the stator fixing assembly also includes a U-shaped seat 13 . The pneumatic chuck 11 and the circular feed motor 12 are both mounted on the U-shaped seat 13 , and the circular feed motor 12 is located at the rear side of the pneumatic chuck 11 .

[0037] Specifically, the U-shaped seat 13 is opened downward and is fixed on the base plate 4 . The chuck mounting seat 15 of the pneumatic chuck 11 and the motor mounting seat I 14 of the circular feed motor 12 are both fixed on the U-shaped seat 13 .

[0038] In order to drive the motor stator on the front end claw 18 of the pneumatic chuck 11 to rotate through the circumferential feed motor 12, a driving gear 16 is installed on the output shaft of the circumferential feed motor 12, and the driving gear 16 is engaged with the transmission gear 17 at the rear end of the pneumatic chuck 11.

[0039] The circular feed motor 12 runs, and its torque is transmitted to the claw 18 at the front end of the pneumatic chuck 11 through the cooperation of the driving gear 16 and the transmission gear 17, and then drives the motor stator to rotate synchronously.

[0040] The existing technology uses a grinding wheel saw to cut copper wire windings, which relies entirely on the friction generated by the grinding wheel saw to drive the motor stator to rotate. This can easily cause severe wear of the grinding wheel saw and shorten its service life. The utility model causes the motor stator to perform a circular motion during the saw blade 21 rotating and cutting, which can effectively solve the problem of severe wear of the saw blade 21, extend the service life of the equipment, and at the same time improve production efficiency and reduce labor intensity.

[0041] Preferably, the circular feed motor 12 is a reduction motor.

[0042] In order to drive the saw blade 21 to rotate and cut the copper wire winding, the cutting motor 22 is located at the rear side of the saw blade 21, and its output shaft is assembled in the central mounting hole of the saw blade 21.

[0043] The saw blade 21 and the cutting motor 22 adopt an integrated sawing and cutting head, that is, the motor shaft of the cutting motor 22 is the mounting shaft of the saw blade 21, and the speed of the cutting motor 22 can be adjusted by a frequency converter.

[0044] Specifically, a pair of clamping plates are provided on the output shaft of the cutting motor 22 , and the saw blade 21 is installed between the two clamping plates and rotates synchronously with the output shaft of the cutting motor 22 .

[0045] In order to protect the saw blade 21 , a protective cover 23 is provided outside the saw blade 21 , and the side of the protective cover 23 facing the stator fixing assembly is opened.

[0046] Specifically, the rear side of the protective cover 23 is mounted on the housing of the cutting motor 22 via two semicircular clamping half rings 24 , that is, one of the clamping half rings 24 is integrally provided with the protective cover 23 , and the clamping half ring 24 is connected to the other clamping half ring 24 via bolts.

[0047] When cutting the copper wire winding, the saw blade 21 needs to be aligned with the boundary line between the copper wire winding and the silicon steel disc, so as to cut off the protruding part of the copper wire winding on the end face of the motor stator to ensure the cutting accuracy. In order to move the saw blade 21 in its axial position, the positioning and feeding component includes an axial slide 31 and an axial slide plate 32 that can slide in the axial direction of the saw blade 21 on the axial slide 31. The cutting motor 22 is installed on the axial slide plate 32.

[0048] Among them, the motor mounting base II 25 of the cutting motor 22 is installed on the axial slide plate 32. By moving the axial slide plate 32 in the axial direction of the saw blade 21, the saw blade 21 is aligned with the boundary line between the copper wire winding and the silicon steel laminations, thereby ensuring the cutting accuracy.

[0049] Preferably, a waist-shaped hole 26 is provided on the motor mounting base II 25. The design of the waist-shaped hole 26 can facilitate the adjustment of the installation position of the cutting motor 22.

[0050] Preferably, the top of the axial slide 31 is of a燕尾型 structure, and the bottom of the axial slide plate 32 is matched with the axial slide 31. This can not only guide the movement between the two, but also prevent the axial slide plate 32 from disengaging from the axial slide 31.

[0051] In order to limit the forward and backward movement of the axial slide plate 32, a pair of axial limit switches 316 that cooperate with the axial slide plate 32 are installed on the side of the axial slide 31.

[0052] Specifically, the axial limit switch 316 is located on the side of the axial slide 31 away from the stator fixing component, and the axial limit switch 316 is fixed to the axial slide 31 through a switch bracket.

[0053] In order to drive the axial slide plate 32 to move in the axial direction of the saw blade 21 to position the saw blade 21, an axial screw rod 33 in the axial direction of the saw blade 21 and an axial positioning motor 34 connected to the rear end of the axial screw rod 33 are installed in the axial slide 31. The bottom of the axial slide plate 32 is connected to the screw nut of the axial screw rod 33.

[0054] Specifically, a motor mounting base III 35 with a "几" shape and an open front is provided at the rear side of the axial slide 31. The axial positioning motor 34 is installed at the rear side of the motor mounting base III 35. A coupling 36 is provided in the motor mounting base III 35. The output shaft of the axial positioning motor 34 is connected to the axial screw rod 33 located in the axial slide 31 through the coupling 36.

[0055] The axial positioning motor 34 runs, driving the axial screw rod 33 to rotate, and the screw nut on the axial screw rod 33 can drive the axial slide 32 to move in the axial direction of the saw blade 21, that is, to move forward or backward, so as to align the saw blade 21 with the dividing line between the copper wire winding and the silicon steel lamination, thereby achieving the effect of positioning the saw blade 21.

[0056] When cutting the copper wire winding, the saw blade 21 needs to be gradually moved closer to the stator fixing assembly until the copper wire winding is completely cut; after the cutting is completed, the saw blade 21 needs to be moved away from the stator fixing assembly and returned to the initial position to facilitate the removal of the cut motor stator from the stator fixing assembly. This process requires the saw blade 21 to be able to move in its horizontal radial direction. In order to achieve this purpose, the positioning and feeding assembly also includes a radial slide 37, and a radial slide 38 that can slide in the horizontal radial direction of the saw blade 21 on the radial slide 37, and the axial slide 31 is installed on the radial slide 38.

[0057] The radial slide 37 is mounted on the base plate 4 , and the radial slide plate 38 is slidably fitted on the radial slide 37 .

[0058] Preferably, the top of the radial slide 37 is a dovetail structure, and the bottom of the radial slide 38 cooperates with the radial slide 37, which not only guides the movement between the two, but also prevents the radial slide 38 from falling off the radial slide 37.

[0059] In order to limit the left and right movement of the radial slide 38 , a pair of radial limit switches 39 cooperating with the radial slide 38 are installed on the rear side of the radial slide 37 .

[0060] The radial limit switch 39 is fixed on the base plate 4 via a switch bracket and is located at the rear side of the radial slide 37 .

[0061] In order to drive the radial slide 38 to move, a radial screw rod 310 located in the horizontal radial direction of the saw blade 21 and a radial feed motor 311 connected to one end of the radial screw rod 310 are installed in the radial slide 37. The bottom of the radial slide 38 is connected to the screw rod nut of the radial screw rod 310.

[0062] Preferably, a locking pin 312 is provided on the front side of the radial slide 38 , and the position of the radial slide 38 can be locked by tightening the locking pin 312 .

[0063] In order to shorten the left and right widths of the entire disassembly mechanism and reduce the space it occupies, the radial feed motor 311 is located on the rear side of the radial slide 37, and a driving pulley 313 is installed at its output end. A driven pulley 314 is installed at the end of the radial screw rod 310 away from the stator fixing assembly, and the driving pulley 313 and the driven pulley 314 are connected by a belt 315.

[0064] The motor mounting seat IV 317 of the radial feed motor 311 is fixed on the base plate 4 , and its output shaft faces the side away from the stator fixing assembly.

[0065] The radial feed motor 311 drives the driving pulley 313 to rotate, and then drives the driven pulley 314 and the radial screw rod 310 to rotate through the belt 315. The screw nut on the radial screw rod 310 can drive the radial slide 38 to move on the radial slide seat 37.

[0066] When disassembling the copper wire windings on the motor stator, the motor stator is placed on the pneumatic chuck 11 and the central axis of the motor stator is clamped using the claws 18 of the pneumatic chuck 11. At this time, the axial positioning motor 34 is started to adjust the axial position of the saw blade 21 so that the saw blade 21 is aligned with the boundary line between the copper wire windings and the silicon steel laminations. After alignment, the radial feed motor 311 is started to drive the saw blade 21 to move radially. Once the saw blade 21 moves to the position of the copper wire windings, the cutting motor 22 and the circumferential feed motor 12 can be started to use the saw blade 21 to cut the copper wire windings. After cutting is completed, the circumferential feed motor 12 and the cutting motor 22 are turned off, and the radial feed motor 311 is used to drive the saw blade 21 back to its initial position. At this point, the cut motor stator can be removed from the pneumatic chuck 11 and replaced with the motor stator to be cut, and the above cutting steps can be repeated. The utility model has a simple overall structure, which not only improves production efficiency and reduces labor intensity, but also can realize fast and accurate cutting of copper wire windings, ensures cutting quality and reduces safety hazards.
