[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Promoting new energy vehicles is to meet the needs of environmental protection and the oil crisis, and to reduce or abandon the current mainstream vehicles that burn traditional gasoline or diesel-driven internal combustion engines. New energy vehicles include four categories: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles. Common motors of new energy vehicles are usually permanent magnet synchronous motors, which are mainly composed of components such as rotors, end covers, and stators.

[0003] During the process of inserting and assembling the rotor of a driving motor of a new energy vehicle into the motor housing, due to the lateral magnetic suction force of the magnet coil on the rotor, when the rotor is inserted into the stator coil, the outer wall of the rotor is likely to rub against the inner wall of the stator coil, easily scratching the outer wall of the rotor and the inner wall of the stator coil, and seriously damaging the winding coil of the stator.

[0014] As a preferred solution of the present invention, two vertically distributed guiding rods are fixedly connected to the top of the base. The two guiding rods are located on both sides of the transfer plate. A lifting platform is slidably connected to the outer walls of the two guiding rods. The lifting platform is located on the back surface of the assembly table, and is fixedly connected between the lifting platform and the assembly table. A lifting lead screw is rotatably connected to the top of the base. The lifting lead screw is located between the two guiding rods. The lifting lead screw movably penetrates the upper and lower surfaces of the lifting platform and is in threaded fit connection with the through hole of the lifting platform.

[0015] As a preferred solution of the present invention, a positioning block is detachably connected to the top of the base by bolts. A positioning column is fixedly connected to the top of the positioning block. A motor housing is movably arranged on the top of the positioning block. The assembly bolt holes of the motor housing are sleeved on the outer periphery of a plurality of positioning columns.

[0016] The usage method of the auxiliary assembly equipment for the rotor of a new energy vehicle drive motor includes the following usage steps:

[0017] S1. Place the motor housing on the top of the positioning block and make its assembly bolt holes sleeved on the outer wall of the positioning column to position the motor housing so that the motor housing cannot move laterally;

[0018] S2. The assembler inserts the rotor that matches the motor housing into the clearance hole from the bottom of the assembly table, and places the rotor shaft between the two arc-shaped chucks, starts the double-rod electric cylinder, and drives the two force plates to move equidistantly toward the middle through the retraction of the two output rods of the double-rod electric cylinder, and further drives the two push rods and the two connecting tripods to move closer to the middle, and drives the two arc-shaped chucks to move synchronously until the two arc-shaped chucks abut against the outer wall of the rotor shaft, and the rotor shaft cannot move further toward the middle after being clamped, and the two force plates are driven by the output rod of the double-rod electric cylinder. The plate moves equidistantly toward the middle. Since the two arc-shaped chucks cannot continue to move due to the reverse force of the rotor shaft, the two push rods slide along the two sliding holes, and the two springs are compressed. The elastic force generated by the two springs pushes the two connecting brackets and the arc-shaped chucks toward the middle, driving the two clamping shoes to move toward the middle, until the two arc-shaped clamping grooves firmly clamp the rotor shaft. At this time, the axis of the rotor and the center of the motor housing are on the same vertical line, and the two arc-shaped chucks drive the two semicircular gears to merge toward the middle, so that the two semicircular gears merge into a complete ring gear.

[0019] S3, the two push rods move toward the middle and drive the two angle bending blocks to move together, further pushing the two first racks toward the middle. In the process of the two first racks moving toward the middle, they will gradually approach the bottom of the two first gears until they mesh with the two first gears, driving the two first gears to rotate in the opposite direction, further making the two first racks rotate in the opposite direction, pushing the two inner wire seats forward and driving the torsion push cross bars to move together, so that the rectangular groove drives the two torsion push rods to move forward. In the process of the two torsion push rods moving forward, they are guided by the first arc-shaped slide groove and the second arc-shaped slide groove, further driving the two T-shaped sliders to slide forward along the T-shaped ring groove until the two covering strips slide to the frontmost position and merge together. At this time, the elastic The wrapped canvas is wrapped around the periphery of the rotor, during which the two vacuum cleaners are running to generate adsorption force, which is transmitted to the inside of the two wrapped strips through two soft ducts, and the dust attached to the surface of the rotor is adsorbed through multiple dust suction ports to prevent the dusty rotor from being transferred to the inside of the stator coil inside the motor housing. When the two angled bent blocks move toward the middle, an angled bent block connected to the rotating rack will drive the rotating rack to move together, pushing the two merged semicircular gears to rotate. The rotation of the two semicircular gears drives the two clamping shoes to rotate along the sliding track of the arc-shaped guide groove and the arc-shaped slider, further driving the clamped rotor to rotate, so that the surface of the rotor can be dusted by the multiple dust suction ports opened on the two wrapped strips;

[0020] S4. After the elastic coated canvas finishes wrapping the rotor, the assembler manually and slowly rotates the handle to drive the lifting lead screw to rotate. Under the action of the thread thrust, the lifting table is released downward. The upward release of the lifting table under the sliding guidance of the two guiding vertical rods will be more stable and smooth. When the lifting table is released downward, it will drive the assembly table to move downward together, further driving the clamped rotor to move downward, and inserting the rotor together with the elastic coated canvas wrapping the rotor into the interior of the motor housing. When the rotor is inserted into the interior of the motor housing, due to the wrapping effect of the elastic coated canvas on the outer wall of the rotor, the outer wall of the rotor will not rub against the stator coil inside the motor housing, avoiding the problems of stator coil damage and coil paint peeling, and ensuring the qualified rate of assembly.

[0021] S5. After the elastic coated canvas finishes wrapping the rotor, as the assembly table continues to be released downward, the outer wall of the elastic coated canvas wrapping the rotor will rub against the inner walls of the two sponge wiping strips, wiping off dust and the like attached to the outer wall of the elastic coated canvas, preventing dust from being carried into the interior of the motor housing. The fixed arm carries the second rack and moves downward synchronously with the assembly table towards the two second gears. Until it meshes with the two second gears and drives the two second gears to rotate in the reverse direction, driving the two adapter shafts to rotate, flipping the two swing arms outwards, and further flipping the two arc-shaped grip plates to both sides, thus avoiding the downward movement of the assembly table.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. In the present invention, when the two push rods move towards the middle, they will drive the two angled bend blocks to move together, further pushing the two first racks towards the middle. During the process of the two first racks moving towards the middle, they will gradually approach the bottoms of the two first gears until they mesh with the two first gears, driving the two first gears to rotate in the reverse direction, further causing the two first racks to rotate in the reverse direction, pushing the two inner thread seats forward and driving the torsion push cross bar to move together, causing the rectangular groove to drive the two torsion push rods to move forward. During the process of the two torsion push rods moving forward, under the guiding action of the first arc-shaped chute and the second arc-shaped chute, they further drive the two T-shaped sliders to slide forward along the T-shaped ring groove until the two coated strips slide to the foremost position and merge together. At this time, the elastic coated canvas wraps around the periphery of the rotor. When the rotor is inserted into the interior of the motor housing, due to the wrapping effect of the elastic coated canvas on the outer wall of the rotor, the outer wall of the rotor will not rub against the stator coil inside the motor housing, avoiding the problems of stator coil damage and coil paint peeling, and ensuring the qualified rate of assembly.

[0024] 2. In the present invention, two dust collectors operate to generate adsorption force, which is transmitted through two flexible ducts to the interiors of two covering strips, and the dust attached to the surface of the rotor is adsorbed through multiple dust suction ports, preventing the rotor with dust from being assembled into the interior of the stator coil inside the motor housing. At the same time, when the two angled blocks move towards the middle, one angled block connected to the turning rack will drive the turning rack to move together, pushing the two combined semi-circular gears to rotate. The rotation of the two semi-circular gears drives the two clamping tiles to rotate along the sliding tracks of the arc-shaped guide groove and the arc-shaped slider, further driving the clamped rotor to rotate, so that the surfaces of the rotor can all be dusted by the multiple dust suction ports provided on the two covering strips.

[0025] 3. In the present invention, the rotor is wrapped by an elastic covering canvas. As the assembly table continues to be lowered, the outer wall of the elastic covering canvas wrapping the rotor will rub against the inner walls of the two sponge wiping strips, wiping off the dust and the like attached to the outer wall of the elastic covering canvas, preventing the dust from being carried into the interior of the motor housing.

[0046] A yielding hole 2001 is penetrated and opened at the top of the assembly table 201. The center of the assembly table 201 coincides with the circle center of the first arc-shaped chute 202. The two arc-shaped chucks 2022 are both semi-circularly arranged. Arc-shaped guiding grooves 20221 are opened on the inner walls of the two arc-shaped chucks 2022.

[0048] Specifically, place the motor housing 12 on top of the positioning block 9, and make all its assembly bolt holes sleeved on the outer wall of the positioning post 10 to position the motor housing 12, preventing it from moving laterally. The assembler inserts the rotor 11 adapted to the motor housing 12 from the bottom of the assembly table 201 into the relief hole 2001, and positions the shaft rod of the rotor 11 between the two arc-shaped chucks 2022. Start the double-rod electric cylinder 2016. The two output rods of the double-rod electric cylinder 2016 retract to drive the two force-applying plates 2017 to move equidistantly towards the middle, further driving the two push rods 2018 and the two connecting brackets 2020 to move closer to the middle, driving the two arc-shaped chucks 2022 to move synchronously until the two arc-shaped chucks 2022 abut against the outer wall of the shaft rod of the rotor 11, clamping the shaft rod of the rotor 11 and preventing it from moving further towards the middle.

The two push rods 2018 moving towards the middle will drive the two angled bent blocks 2023 to move together, further pushing the two first racks 2024 towards the middle. During the process of the two first racks 2024 moving towards the middle, they will gradually approach the bottom of the two first gears 2015 until they mesh with the two first gears 2015, driving the two first gears 2015 to rotate in the reverse direction, further causing the two first racks 2024 to rotate in the reverse direction, pushing the two internal thread seats 2012 forward and driving the torsion push cross bar 2010 to move together, causing the rectangular groove 2011 to drive the two torsion push rods 209 forward. During the process of the two torsion push rods 209 moving forward, under the guiding action of the first arc-shaped chute 202 and the second arc-shaped chute 205, they further drive the two T-shaped sliders 206 to slide forward along the T-shaped ring groove 204 until the two covering strips 207 slide to the frontmost position and merge together. At this time, the elastic covering canvas 208 wraps around the periphery of the rotor 11. During this period, the two dust collectors 13 operate to generate an adsorption force, which is transmitted to the inside of the two covering strips 207 through the two soft ducts, and the dust attached to the surface of the rotor 11 is adsorbed through the multiple dust suction ports 2071, preventing the dusty rotor 11 from being assembled into the stator coil inside the motor housing 12. When the two angled bent blocks 2023 move towards the middle,A corner bending block 2023 connected to the turning rack 20226 will drive the turning rack 20226 to move together, pushing the two combined semi-circular gears 20225 to rotate. The rotation of the two semi-circular gears 20225 drives the two clamping tiles 20223 to rotate along the sliding tracks of the arc-shaped guide groove 20221 and the arc-shaped slider 20222, further driving the clamped rotor 11 to rotate, so that the surface of the rotor 11 can be dusted by the multiple dust suction ports 2071 opened on the two covering strips 207. When the elastic covering canvas 208 finishes wrapping the rotor 11, the assembler manually and slowly rotates the handle 8 to drive the lifting lead screw 7 to rotate. Under the action of the thread thrust, the lifting table 6 is released downward. The lifting table 6 will be more stable and smooth when it is released upward under the sliding guidance of the two guiding vertical rods 5. When the lifting table 6 is released downward, it will drive the assembly table 201 to move downward together, further driving the clamped rotor 11 to move downward, and inserting the rotor 11 together with the elastic covering canvas 208 that wraps the rotor 11 into the motor housing 12. When the rotor 11 is inserted into the motor housing 12, due to the wrapping effect of the elastic covering canvas 208 on the outer wall of the rotor 11, the outer wall of the rotor 11 will not rub the stator coil inside the motor housing 12, avoiding the damage of the stator coil and the problem of coil paint peeling, and ensuring the qualification rate of the assembly.

[0049] Embodiment 2:

[0050] On the basis of Embodiment 1, the wiping assembly 3 includes an adapter plate 301. The adapter plate 301 is fixedly connected to the rear end of the top of the base 1. Two left-right distributed adapter shafts 302 are rotatably connected inside the adapter plate 301. Both of the two adapter shafts 302 movably penetrate through the front and back of the adapter plate 301. Swing arms 303 are fixedly connected to the outer walls of the two adapter shafts 302. The two swing arms 303 are located at the front end of the adapter plate 301. Connecting rods 304 are fixedly connected to the lower parts of the fronts of the two swing arms 303. Arc-shaped grip plates 305 are fixedly connected to the ends of the two connecting rods 304 away from the two swing arms 303. Sponge wiping strips 306 are fixedly connected to the inner walls of the two arc-shaped grip plates 305;

[0051] Second gears 307 are fixedly connected to the front ends of the two adapter shafts 302. A fixed arm 4 is fixedly connected to the rear end of the top of the assembly table 201. A second rack 308 is fixedly connected to the back of the fixed arm 4. The second rack 308 is located in the upper part between the two adapter shafts 302. The specifications of the second rack 308 are adapted to the specifications of the two second gears 307.

[0052] Specifically, when the elastic covering canvas 208 finishes wrapping the positioning post 10, as the assembly table 201 continues to move downward and release, the outer wall of the elastic covering canvas 208 wrapping the positioning post 10 will rub against the inner walls of the two sponge wiping strips 306, wiping off dust and the like attached to the outer wall of the elastic covering canvas 208, preventing the dust from being carried into the interior of the motor housing 12. The fixed arm 4 carries the second rack 308 and moves downward synchronously with the assembly table 201 towards the two second gears 307. Until it meshes with the two second gears 307 and drives the two second gears 307 to rotate in the reverse direction, driving the two transfer shafts 302 to rotate, turning the two swing arms 303 outwards, and further turning the two arc-shaped grip plates 305 to both sides, thereby avoiding the downward movement of the assembly table 201.

[0053] Embodiment 3:

[0054] On the basis of Embodiment 2, end caps 309 are fixedly connected to the rear ends of the two transfer shafts 302. Torsion springs 3010 are fixedly connected to the fronts of the two end caps 309. The two torsion springs 3010 are located around the two transfer shafts 302. The front ends of the two torsion springs 3010 are fixedly connected to the back of the transfer plate 301. A limit wedge 3011 is fixedly connected to the front of the transfer plate 301. The limit wedge 3011 is located between the two swing arms 303. The left and right side surfaces of the limit wedge 3011 are in contact with the side surfaces of the two swing arms 303 that are close to each other;

[0055] Specifically, when the two transfer shafts 302 drive the two swing arms 303 to turn to both sides, they drive the two torsion springs 3010 to rotate together, causing the two torsion springs 3010 to twist and generate elastic potential energy. Thus, when the assembly of the positioning post 10 and the motor housing 12 is completed, by starting the double-rod electric cylinder 2016, the two connecting footrests 2020 are further moved to both sides to release the clamping of the positioning post 10. Reverse the turning handle 8. By the same principle as above, the assembly table 201 moves upward. The second rack 308 will drive the two swing arms 303 to rotate back, closing the two swing arms 303 and the arc-shaped grip plates 305 towards the middle. At this time, the elastic force of the two torsion springs 3010 is released. When the two swing arms 303 rotate and close towards the middle, the elastic force of the two torsion springs 3010 will turn the two swing arms 303 towards the middle, ensuring that the two arc-shaped grip plates 305 are completely in contact with each other. And under the limitation of the limit wedge 3011, the two arc-shaped grip plates 305 are located exactly in the middle, so as to accurately release the elastic covering canvas 208 wrapped around the periphery of the positioning post 10.

[0056] The usage method of the new energy vehicle drive motor rotor auxiliary assembly equipment includes the following usage steps:

[0057] S1. Place the motor housing 12 on the top of the positioning block 9, and make its assembly bolt holes all sleeved on the outer wall of the positioning post 10 to position the motor housing 12, so that the motor housing 12 cannot move laterally;

[0058] S2. The assembler inserts the rotor 11 adapted to the motor housing 12 from the bottom of the assembly table 201 into the relief hole 2001, and places the shaft rod of the rotor 11 between the two arc-shaped chucks 2022. Then, the double-rod electric cylinder 2016 is started. The two output rods of the double-rod electric cylinder 2016 retract to drive the two force-applying plates 2017 to move equidistantly towards the middle, further driving the two push rods 2018 and the two connecting brackets 2020 to move closer to the middle, driving the two arc-shaped chucks 2022 to move synchronously until the outer walls of the two arc-shaped chucks 2022 are in contact with the shaft rod of the rotor 11. After clamping the shaft rod of the rotor 11, they cannot continue to move towards the middle. Then, the output rods of the double-rod electric cylinder 2016 continue to drive the two force-applying plates 2017 to move equidistantly towards the middle. Since the two arc-shaped chucks 2022 cannot continue to move due to the reaction force from the shaft rod of the rotor 11, the two push rods 2018 slide along the two sliding holes 2025, and the two springs 2019 are compressed. The elastic force generated by the two springs 2019 pushes the two connecting brackets 2020 and the arc-shaped chucks 2022 towards the middle, driving the two clamping tiles 20223 to move towards the middle until the two arc-shaped grooves 20224 firmly clamp the shaft rod of the rotor 11. At this time, the axis of the rotor 11 and the center of the motor housing 12 are on the same vertical line, and the two arc-shaped chucks 2022 drive the two semi-circular gears 20225 to merge towards the middle, so that the two semi-circular gears 20225 are combined into a complete ring gear;

[0059] S3. When the two push rods 2018 move towards the middle, they will drive the two angled bending blocks 2023 to move together, further pushing the two first rack bars 2024 towards the middle. During the process of the two first rack bars 2024 moving towards the middle, they will gradually approach the bottoms of the two first gears 2015 until they mesh with the two first gears 2015, driving the two first gears 2015 to rotate in the reverse direction. Further, the two first rack bars 2024 will rotate in the reverse direction, pushing the two internal thread seats 2012 forward and driving the torsion push cross bar 2010 to move together, causing the rectangular groove 2011 to drive the two torsion push rods 209 to move forward. During the process of the two torsion push rods 209 moving forward, under the guiding action of the first arc-shaped chute 202 and the second arc-shaped chute 205, they will further drive the two T-shaped sliders 206 to slide forward along the T-shaped ring groove 204 until the two covering strips 207 slide to the foremost position and merge together. At this time, the elastic covering canvas 208 wraps around the periphery of the rotor 11. During this period, the two dust collectors 13 operate to generate suction force, which is transmitted through the two soft ducts to the interiors of the two covering strips 207, and the dust attached to the surface of the rotor 11 is sucked off through multiple dust suction ports 2071, preventing the dusty rotor 11 from being assembled into the stator coil inside the motor housing 12. When the two angled bending blocks 2023 move towards the middle, one angled bending block 2023 connected to the turning rack bar 20226 will drive the turning rack bar 20226 to move together, pushing the two combined semi-circular gears 20225 to rotate. The rotation of the two semi-circular gears 20225 drives the two clamping tiles 20223 to rotate along the sliding tracks of the arc-shaped guiding groove 20221 and the arc-shaped slider 20222, further driving the clamped rotor 11 to rotate, so that the surface of the rotor 11 can be dust-removed by the multiple dust suction ports 2071 provided on the two covering strips 207;

[0060] S4. After the elastic covering canvas 208 finishes wrapping the rotor 11, the assembler manually and slowly rotates the handle 8 to drive the lifting lead screw 7 to rotate. Under the action of the thread thrust, the lifting platform 6 is released downward. The lifting platform 6 will be more stable and smooth when it is released upward under the sliding guidance of the two guiding vertical rods 5. When the lifting platform 6 is released downward, it will drive the assembly table 201 to move downward together, further driving the clamped rotor 11 to move downward, and inserting the rotor 11 together with the elastic covering canvas 208 that wraps the rotor 11 into the interior of the motor housing 12. When the rotor 11 is inserted into the interior of the motor housing 12, due to the wrapping effect of the elastic covering canvas 208 on the outer wall of the rotor 11, the outer wall of the rotor 11 will not rub against the stator coil inside the motor housing 12, avoiding the problems of stator coil damage and coil paint peeling, and ensuring the assembly qualification rate;

[0061] S5. When the elastic coated canvas 208 completes wrapping the rotor 11, as the assembly platform 201 continues to be released downward, the outer wall of the elastic coated canvas 208 wrapping the rotor 11 will rub against the inner walls of the two sponge wiping strips 306, and the dust and the like attached to the outer wall of the elastic coated canvas 208 will be wiped off to avoid carrying the dust into the motor housing 12. The fixed arm 4 carries the second rack 308 and moves synchronously downward with the assembly platform 201 to approach the two second gears 307 until it engages with the two second gears 307 and drives the two second gears 307 to rotate in the opposite direction, driving the two transfer shafts 302 to rotate, flipping the two swing arms 303 to the outside, and further flipping the two arc-shaped gripping plates 305 to both sides, thereby avoiding the assembly platform 201 from moving downward.

[0062] When the new energy vehicle drive motor rotor auxiliary assembly device of this scheme is working, the motor housing 12 is placed on the top of the positioning block 9, and the assembly bolt holes are all sleeved on the outer wall of the positioning column 10 to position the motor housing 12, so that the motor housing 12 cannot move sideways;

[0063] The assembler inserts the rotor 11 matched with the motor housing 12 into the clearance hole 2001 from the bottom of the assembly table 201, and places the shaft of the rotor 11 between the two arc-shaped clamps 2022, and starts the double-rod electric cylinder 2016. The two output rods of the double-rod electric cylinder 2016 retract and drive the two force plates 2017 to move equidistantly toward the middle, and further drive the two push rods 2018 and the two connecting legs 2020 to move toward the middle, and drive the two arc-shaped clamps 2022 to move synchronously until the two arc-shaped clamps 2022 abut against the outer wall of the shaft of the rotor 11, and the shaft of the rotor 11 is assembled. After clamping, it cannot move further toward the middle, and the output rod of the double-rod electric cylinder 2016 continues to drive the two force plates 2017 to move equidistantly toward the middle. Since the two arc-shaped clamps 2022 cannot move further due to the reverse force of the shaft of the rotor 11, the two push rods 2018 slide along the two sliding holes 2025, and the two springs 2019 are compressed. The elastic force generated by the two springs 2019 pushes the two connecting legs 2020 and the arc-shaped clamps 2022 toward the middle to firmly clamp the shaft of the rotor 11. At this time, the axis of the rotor 11 and the center of the circle of the motor housing 12 are on the same vertical line;

[0064] When the two push rods 2018 move towards the middle, they will drive the two angled bending blocks 2023 to move together, further pushing the two first racks 2024 towards the middle. During the process of the two first racks 2024 moving towards the middle, they will gradually approach the bottoms of the two first gears 2015 until they mesh with the two first gears 2015, driving the two first gears 2015 to rotate in the reverse direction. Further, the two first racks 2024 will rotate in the reverse direction, pushing the two internal thread seats 2012 forward and driving the torsion push cross bar 2010 to move together, causing the rectangular groove 2011 to drive the two torsion push rods 209 to move forward. During the process of the two torsion push rods 209 moving forward, under the guiding action of the first arc-shaped chute 202 and the second arc-shaped chute 205, they will further drive the two T-shaped sliders 206 to slide forward along the T-shaped ring groove 204 until the two covering strips 207 slide to the foremost position and merge together. At this time, the elastic covering canvas 208 wraps around the periphery of the rotor 11;

[0065] After the elastic covering canvas 208 finishes wrapping the rotor 11, the assembler manually and slowly rotates the turning handle 8 to drive the lifting lead screw 7 to rotate. Under the action of the thread thrust, the lifting table 6 is released downward. The lifting table 6 will be more stable and smooth when it is released upward under the sliding guidance of the two guiding vertical rods 5. When the lifting table 6 is released downward, it will drive the assembly table 201 to move downward together, further driving the clamped rotor 11 to move downward. The rotor 11 together with the elastic covering canvas 208 that wraps the rotor 11 is inserted into the interior of the motor housing 12. When the rotor 11 is inserted into the interior of the motor housing 12, due to the wrapping effect of the elastic covering canvas 208 on the outer wall of the rotor 11, the outer wall of the rotor 11 will not rub against the stator coil inside the motor housing 12, avoiding the problems of stator coil damage and coil paint peeling, and ensuring the assembly qualification rate;

[0066] After the elastic covering canvas 208 finishes wrapping the rotor 11, as the assembly table 201 continues to be released downward, the outer wall of the elastic covering canvas 208 that wraps the rotor 11 will rub against the inner walls of the two sponge wiping strips 306, wiping off the dust and the like attached to the outer wall of the elastic covering canvas 208, preventing the dust from being carried into the interior of the motor housing 12. The fixed arm 4 carries the second rack 308 and moves downward synchronously with the assembly table 201 towards the two second gears 307. Until it meshes with the two second gears 307 and drives the two second gears 307 to rotate in the reverse direction, driving the two adapter shafts 302 to rotate, flipping the two swing arms 303 outwards, and further flipping the two arc-shaped grip plates 305 to both sides, thus avoiding the downward movement of the assembly table 201.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

The assembler inserts the rotor (11) adapted to the motor housing (12) from the bottom of the assembly table (201) into the clearance hole (2001), and places the shaft of the rotor (11) between the two arc-shaped chucks (2022), starts the double-rod electric cylinder (2016), and drives the two force plates (2017) to move equidistantly toward the middle through the retraction of the two output rods of the double-rod electric cylinder (2016), further drives the two push rods (2018) and the two connecting legs (2020) to move toward the middle, and drives the two arc-shaped chucks (2022) to move synchronously until the two arc-shaped chucks (2022) abut against the outer wall of the shaft of the rotor (11), and the shaft of the rotor (11) cannot move further toward the middle after being clamped, and continues to drive the two force plates (2017) through the output rod of the double-rod electric cylinder (2016). The two arc-shaped chucks (2022) are moved equidistantly toward the middle. Since the two arc-shaped chucks (2022) are unable to move further due to the reverse force of the shaft of the rotor (11), the two push rods (2018) slide along the two sliding holes (2025), and the two springs (2019) are compressed. The elastic force generated by the two springs (2019) pushes the two connecting legs (2020) and the arc-shaped chucks (2022) toward the middle, driving the two clamping shoes (20223) to move toward the middle, until the two arc-shaped clamping grooves (20224) firmly clamp the shaft of the rotor (11). At this time, the axis of the rotor (11) and the center of the circle of the motor housing (12) are on the same vertical line, and the two arc-shaped chucks (20222) drive the two semicircular gears (20225) to merge toward the middle, so that the two semicircular gears (20225) merge into a complete ring gear; S3. The two push rods (2018) move toward the middle, which drives the two corner bends (2023) to move together, further pushing the two first racks (2024) toward the middle. In the process of moving toward the middle, the two first racks (2024) gradually approach the bottom of the two first gears (2015) until they mesh with the two first gears (2015), driving the two first gears (2015) to rotate in the opposite direction, further causing the two first racks (2024) to rotate in the opposite direction, and moving the two inner thread seats (2 012) pushes the torsion push bar (2010) forward, so that the rectangular groove (2011) drives the two torsion push rods (209) to move forward. During the forward movement of the two torsion push rods (209), they are guided by the first arc-shaped slide groove (202) and the second arc-shaped slide groove (205), and further drive the two T-shaped sliders (206) to slide forward along the T-shaped ring groove (204), until the two covering strips (207) slide to the frontmost position and merge together. At this time, the elastic covering canvas (2 08) is wrapped around the outer periphery of the rotor (11), during which the two vacuum cleaners (13) operate to generate an adsorption force, which is transmitted to the inside of the two covering strips (207) through the two soft ducts, and the dust attached to the surface of the rotor (11) is adsorbed through the multiple dust suction ports (2071), thereby preventing the rotor (11) with dust from being transferred to the inside of the stator coil in the motor housing (12). When the two angled bends (2023) move toward the middle, an angled bend (2023) connected to the rotating rack (20226) is 23) will drive the rotating rack (20226) to move together, pushing the two merged semicircular gears (20225) to rotate, and the rotation of the two semicircular gears (20225) drives the two clamping shoes (20223) to rotate along the sliding track of the arc-shaped guide groove (20221) and the arc-shaped slider (20222), further driving the clamped rotor (11) to rotate, so that the surface of the rotor (11) can be dusted by the multiple dust suction ports (2071) opened on the two covering strips (207); S4. After the elastic coated canvas (208) has finished wrapping the rotor (11), the assembler manually and slowly rotates the handle (8) to drive the lifting screw (7) to rotate. Under the action of the thread thrust, the lifting platform (6) is released downward. The lifting platform (6) is guided upward by the two guide vertical rods (5) to be released more stably and smoothly. When the lifting platform (6) is released downward, it drives the assembly platform (201) to move downward together, and further drives the clamped rotor (11) to move downward. The rotor (11) is connected to the elastic coated canvas (208) that wraps the rotor (11) and inserted into the motor housing (12). When the rotor (11) is inserted into the motor housing (12), the outer wall of the rotor (11) is wrapped by the elastic coated canvas (208). The outer wall of the rotor (11) does not rub against the stator coil inside the motor housing (12), thereby avoiding damage to the stator coil and paint cracking of the coil, thereby ensuring the qualified rate of assembly. S5. When the elastic coated canvas (208) completes wrapping the rotor (11), as the assembly platform (201) continues to be released downward, the outer wall of the elastic coated canvas (208) wrapping the rotor (11) will rub against the inner walls of the two sponge wiping strips (306), thereby wiping off dust attached to the outer wall of the elastic coated canvas (208) to prevent dust from being carried into the motor housing (12). The fixed arm (4) carries the second rack (308) and moves synchronously downward with the assembly platform (201) toward the two second gears (307) until it meshes with the two second gears (307) and drives the two second gears (307) to rotate in the opposite direction, driving the two transfer shafts (302) to rotate, flipping the two swing arms (303) toward the periphery, and further flipping the two arc-shaped gripping plates (305) to both sides, thereby avoiding the assembly platform (201) from moving downward.
