[0001] The utility model relates to the field of production and processing of automobile seat drivers, in particular to motor rotor assembly equipment for automobile seat drivers. Background Art

[0002] Car seats provide drivers and passengers with easy-to-use, comfortable, and safe driving and riding positions. Car seats can be adjusted manually or electrically. Electrically adjustable car seats primarily utilize a driver to move the seat or adjust the backrest angle.

[0003] The motor is the main power component in the driver, and the motor mainly includes the motor rotor. The two ends of the motor rotor need to be installed with retaining springs and bearings. In the prior art, when the retaining springs and bearings are assembled, a separate retaining spring assembly device is generally used to assemble the retaining springs at both ends of the motor rotor. After the retaining springs are assembled, they are stacked in a material tray. After the material tray is full, it is transferred to the bearing assembly device for press-fitting the bearings. In this method, manual material transfer is required, the assembly efficiency is relatively low, and the space occupied is relatively large. At the same time, in the prior art, the press-fitting of bearings is generally semi-automatic, such as application number: 202323370937.1, patent name: A semi-automatic bearing pressing machine for motor rotor bearing installation.

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0056] Example 1: See Figure 1-12 As shown, an assembly device for a motor rotor for an automobile seat driver includes a machine platform 1, a circlip assembly device 2 mounted on a top table panel 11 of the machine platform 1, a bearing assembly device further provided on the rear side of the circlip assembly device 2, and a discharge portion 3 provided on the table panel 11. The discharge portion 3 is disposed between the circlip assembly device 2 and the bearing assembly device. The bearing assembly device includes two sets of bearing assembly mechanisms symmetrically disposed on both sides of the discharge portion 3.

[0057] The bearing assembly mechanism includes a bearing press-fitting mechanism 6 and a bearing feeding mechanism 5 , wherein the bearing press-fitting mechanism 6 is arranged between the bearing feeding mechanism 5 and the retaining spring assembly device 2 ;

[0058] The bearing press-fitting mechanism includes a bearing positioning portion and a driving portion. A positioning member 61 is provided on the table panel 11. The bottom of the bearing positioning portion is slidably mounted on the positioning member 61. The driving portion is configured to drive the bearing positioning portion to move along the positioning member.

[0059] The bearing positioning portion includes a slide 62, a bearing positioning block 63 rotatably mounted on the slide 62, and a rotation driving portion 64 driving the bearing positioning block 63 to rotate. The slide 62 is slidably disposed on the positioning member 61.

[0060] In the utility model, the discharge part is longitudinally arranged in the middle of the table panel, and is arranged longitudinally from front to back for conveying the motor rotor. When the motor rotor is conveyed to the retaining spring assembly device, the retaining spring assembly device simultaneously assembles retaining springs on both ends of the motor rotor. After the circlip is assembled, it is sent to the rear end through the discharge part and is located between the two sets of bearing pressing mechanisms. The bearing loading mechanism is used for stacking and conveying bearings. When the bearing is in the bearing loading mechanism, the axis of the bearing is perpendicular to the axis of the motor rotor. Therefore, a rotary drive part is provided on the bearing pressing mechanism. The rotary drive part can drive the bearing locating part to rotate 90 degrees. When receiving the material, the rotary drive part drives the bearing locating block to rotate 90 degrees so that the bearing locating block is facing the bearing feeding mechanism. The bearing feeding mechanism sends a bearing into the bearing locating block, and then the rotary drive part drives the bearing locating block to rotate 90 degrees in the opposite direction so that the bearing locating block is facing the discharge part and the motor rotor of the bearing to be assembled. At this time, the axis of the bearing and the axis of the motor shaft are parallel and coaxial, and then the bearing locating part is driven by the drive part to move toward the motor rotor to press the bearing on the motor rotor to complete the bearing press.

[0061] In this embodiment, the retaining spring assembly device adopts two groups of retaining spring assembly mechanisms symmetrically arranged on both sides of the discharge part 3. The retaining spring assembly mechanism includes a vibrating loading tray 21, a loading chute 22 and a manipulator 23. The vibrating loading tray sorts the retaining springs and transports them to the loading chute at one time. Then, the manipulator grabs one retaining spring from the loading chute each time (the opening of the retaining spring is set downward), presses it down and clamps it on the motor rotor to achieve rapid assembly of the retaining spring.

[0062] See also Figure 3-9 As shown, the middle portion of the bearing positioning block 63 is provided with a bearing push hole 65 with two ends passing through, and one end of the bearing positioning block 63 is further provided with a bearing positioning hole 66 coaxially arranged with the bearing push hole 65, and the diameter of the bearing positioning hole 66 is larger than the diameter of the bearing push hole 65;

[0063] The driving part includes a first driving part 67 that drives the bearing positioning part to move along the positioning member 61 and a second driving part 68 arranged at the outer end of the slide 62. The second driving part 68 is provided with a push rod 69. The second driving part 68 drives the inner end of the push rod 69 to be inserted into the bearing push hole 65 or to be separated from the bearing push hole 65.

[0064] During operation, the rotary drive unit drives the bearing positioning block to rotate so that the bearing positioning hole is opposite to the bearing feeding mechanism, and then the bearing feeding mechanism feeds the bearing into the bearing positioning hole. The rotary drive unit drives the bearing positioning block to rotate so that the bearing positioning hole is set inward and opposite to the motor rotor on the discharge unit. At this time, the bearing positioning hole and the bearing are facing the end of the motor rotor, and the bearing positioning hole and the axis of the motor rotor are coaxially arranged. Then the first drive unit drives the bearing positioning block and the bearing above it to move inward, so that the bearing and the end of the motor rotor contact, and the second drive unit drives the push rod to move inward so that the inner end of the push rod is inserted into the bearing push hole and contacts the end of the bearing, pushing the bearing to move inward and press-fit on the motor rotor. After the bearing is pressed into place, the second drive unit drives the push rod to move outward to disengage from the bearing push hole, that is, disengage from the bearing positioning block. At this time, the first drive unit will also drive the bearing positioning unit to move outward away from the rotor, return to its original position, and wait for the next bearing press-fitting action.

[0065] See also Figure 3 、 4 As shown in Figures 7 and 7, the push rod 69 is arranged parallel to the extension direction of the positioning member 61, the middle part of the push rod 69 is movably connected to the slide 62, the fixed end of the second driving part 68 is installed on the table panel 11, the driving end of the second driving part 68 is arranged opposite to the bearing positioning part, and the driving end of the second driving part 68 is connected to the outer end of the push rod 69.

[0066] In this embodiment, since the outer end of the push rod is connected to the driving end of the second driving part, if the push rod moves outward and completely disengages from the bearing positioning part, the inner end of the push rod is not supported. It is a suspended structure at one end and is easily deformed by weight. When it moves inward subsequently, it may not be smoothly inserted into the bearing push hole. Therefore, the middle part of the push rod is movably connected to the slide, and the push rod can be supported, supported and guided by the slide to ensure that when the push rod moves inward, it can be stably inserted into the bearing push hole to push and press the bearing.

[0067] See also Figure 7 As shown, the inner end of the push rod 69 is provided with a clearance hole 601, and the inner surface of the inner end of the clearance hole 601 is provided with a tapered guide hole 602.

[0068] Since the bearing needs to be installed on the motor rotor, after the bearing is installed, there is a certain distance between the end face of the bearing and the end face of the motor rotor. Therefore, in order to ensure that the bearing is installed in place, a clearance hole is provided, so that during the bearing press-fitting process, the clearance hole is used to make way for the end of the motor rotor, ensuring that the push rod can smoothly push the bearing sleeve onto the motor rotor and make the bearing press-fitted in place. The setting of the tapered guide hole facilitates the processing of the clearance hole and can also ensure that the end of the motor rotor can be smoothly inserted into the clearance hole.

[0069] Among them, the second driving part 68 is a second driving cylinder. When the output shaft of the second driving cylinder is extended, the inner end of the push rod 69 passes through the bearing push hole 65 and the bearing positioning hole 66 and leaks out of the outside of the bearing positioning block 63, thereby pushing the bearing out of the bearing positioning hole and press-fitting it on the motor rotor.

[0070] When the output shaft of the second driving cylinder is in a retracted state, the inner end of the push rod moves outward to disengage from the bearing push hole and is disposed outside the bearing positioning block, thereby not affecting the rotation of the bearing positioning block.

[0071] The second driving cylinder can be an air cylinder or an oil cylinder. If a larger pressing force is required, an oil cylinder can be used. If a smaller pressing force is required, an air cylinder can be used.

[0072] See also Figure 3-5 As shown, the first driving part 67 is installed on the table panel 11, the first driving part 67 is a first driving cylinder, the fixed end of the first driving cylinder is connected to the table panel 11, and the driving end of the first driving cylinder is connected to the slide 62; when the output shaft of the first driving cylinder is extended, the slide 62 is pushed away from the second driving part 68; when the output shaft of the first driving cylinder is retracted, the slide 62 is pulled close to the second driving part 68.

[0073] The first drive cylinder adopts an air cylinder or an oil cylinder. In this embodiment, the first drive cylinder adopts an air cylinder. When the cylinder output shaft extends, it drives the slide to move inward. When the slide moves inward, it synchronously drives the bearing positioning block and the bearing above it to move inward close to the motor rotor, and makes the bearing rest against the end of the motor rotor. At the same time, the second drive cylinder output shaft extends, and the bearing is pushed onto the rotor through the push rod.

[0074] Due to the existence of the clearance hole, when the bearing is press-fitted onto the motor rotor, when one side of the motor rotor is inserted into the clearance hole, the end of the clearance hole presses against the motor rotor, so that both sides of the motor rotor are limited by the push rods on both sides, thereby ensuring that the bearings on both sides are press-fitted into place.

[0075] See also Figure 3 、 6 As shown, the first driving portion 67 is mounted on the bottom surface of the table panel 11. The bottom surface of the table panel 11 is provided with a first strip-shaped through groove communicating with the top surface of the table panel 11. The bottom of the slide 62 is connected to the driving end of the first driving portion 67 via the first vertical plate 603.

[0076] An adjustable stopper 604 is further provided on the bottom surface of the table panel 11 . The stopper 604 is disposed at the inner end of the first vertical plate 603 . The stopper is a bolt, so that the distance between the stopper and the first vertical plate can be adjusted.

[0077] In this embodiment, the first drive cylinder is mounted on the bottom surface of the tabletop, without interfering with the installation of the second drive cylinder or the push rod. The presence of the stopper limits the inward movement of the carriage, ensuring that the carriage stops moving inward after reaching a predetermined position. Furthermore, when the second drive cylinder drives the push rod inward, the bearing cannot move further after the end of the motor rotor is inserted into the end of the clearance hole, ensuring stable and accurate bearing installation. This requires only careful verification of the clearance hole's machining depth.

[0078] See also Figure 3 、 4 As shown in Figure 6, the slide 62 is a U-shaped structure. A U-shaped groove 605 is provided on the slide 62. The opening of the U-shaped groove 605 is set inward. The bearing positioning block 63 is rotatably installed in the U-shaped groove 605 via a rotating shaft 606. The rotation drive part 64 is configured to drive the rotating shaft 606 to rotate; the middle part of the rotating shaft is connected to the bearing positioning block, and the circumferential rotation of the rotating shaft and the bearing positioning block can be limited by using a spline.

[0079] The bottom of the slide 62 is slidably connected to the positioning member 61, and the bottom plane of the U-shaped groove 605 is set above the top plane of the positioning member 61, so that when the bearing positioning block rotates, the positioning member will not affect the rotation of the bearing positioning block.

[0080] See also Figure 3 、 4 As shown in Figure 6, the rotating drive part 64 is installed on the top of the slide 62, the middle part of the rotating shaft 606 is connected to the bearing positioning block 63, the bottom of the rotating shaft 606 is rotatably connected to the bottom of the U-shaped groove 605, the top of the rotating shaft 606 is rotatably connected to the top of the U-shaped groove 605, and the top of the rotating shaft 606 passes through the U-shaped groove 605 and is arranged above the top of the slide 62.

[0081] The rotation driving unit 64 includes a gear 641, a rack 642, and a third driving cylinder 643. The gear 641 is mounted on the top outer surface of the rotating shaft 606. The rack 642 is disposed beside the gear 641 and meshes with the gear 641.

[0082] The third drive cylinder 643 is installed on the top of the slide 62, and the output shaft of the third drive cylinder 643 is connected to the end of the rack 642. The third drive cylinder 643 is configured to drive the rack 642 to move and drive the rotating shaft 606 and the bearing positioning block 63 to rotate through the gear 641.

[0083] A sliding limit block 644 is also provided on the top of the slide 62. The sliding limit block 644 is arranged next to the gear 641. A sliding groove 645 facing the gear 641 is provided on the side wall of the sliding limit block 644. The rack 642 is slidably set in the sliding groove 645.

[0084] In this embodiment, the third drive cylinder is a pneumatic cylinder. The extension and retraction of the third drive cylinder's output shaft drives the rack. The meshing of the rack and gear drives the bearing positioning block to rotate 90° clockwise and 90° counterclockwise, respectively. After receiving the material from the rear side, the bearing positioning hole is rotated to the inner end, and the bearing is subsequently press-fitted. The provision of a sliding stopper limits the travel distance of the rack, thereby precisely controlling the bearing positioning block's rotation angle, specifically, precisely controlling the bearing positioning block's 90-degree rotation.

[0085] See also Figure 1 、 5 As shown in 10-12, the bearing feeding mechanism includes a feeding block 51 and a feeding component mounted on the table panel 11. The feeding block 51 is provided with a feeding trough 52 that is inclined downward from the outside to the inside, and the top of the outer end of the feeding trough 52 is connected to the top surface of the feeding block 51;

[0086] A discharge port 53 communicating with the inner end of the feed trough 52 is provided on the front side of the loading block 51, and a through port 54 communicating with the inner end of the feed trough 52 is provided on the rear side of the loading block 51. The through port 54 is arranged opposite to the discharge port 53, and the discharge port is arranged opposite to the bearing positioning block.

[0087] The feeding component is installed on the rear side of the loading block 51, and the feeding component includes a feeding cylinder 55 and a feeding rod 56. The feeding cylinder 55 is installed on the rear side of the loading block 51, and the rear end of the feeding rod 56 is connected to the output shaft of the feeding cylinder 55. The front end of the feeding rod 56 is inserted into the through opening 54. The feeding cylinder 55 drives the feeding rod 56 to move back and forth. When the output shaft of the feeding cylinder 55 is retracted, the front end of the feeding rod 56 is retracted into the through opening 54; when the output shaft of the feeding cylinder 55 is extended, the front end of the feeding rod 56 passes through the feeding trough 52 and the discharge port 53 and is arranged on the front side of the loading block 51, and pushes the bearing in the discharge trough into the bearing positioning block. When the bearing positioning hole of the bearing positioning block rotates to face the discharge port, the feed cylinder drives the feed rod forward, pushing a bearing forward into the bearing positioning hole. The bearing positioning block then rotates 90 degrees in the opposite direction, so that the bearing positioning hole faces the motor rotor above the discharge section, and the subsequent bearing press-fitting operation is carried out. During the bearing press-fitting operation, the feed cylinder drives the feed rod backward, and the next bearing rolls into the feed trough at the discharge port, waiting for the next bearing to be fed.

[0088] In this arrangement, the mechanism can be set on both sides of the extension direction of the discharge section as much as possible, and the space on both sides of the discharge section for conveying the motor rotor can be fully utilized, which can reduce the waste of space and make the motor rotor in an automated production line during the manufacturing process. In this embodiment, the bearing 13 enters the feed trough from the outer top of the feed trough, and the bearing rolls inwardly into the feed trough at the discharge port through the inclined feed trough. After rolling into the feed trough at the discharge port, it waits for the bearing press-fitting mechanism to receive the material. When a bearing is fed into the bearing press-fitting mechanism, the output shaft of the feed cylinder extends, driving the feed rod to push forward, pushing the bearing out of the discharge port and into the bearing press-fitting mechanism, and then the feed cylinder output shaft retracts to its original position (when the feed rod moves forward, it blocks the bearing on the side of the feed trough at the discharge port position, preventing the bearing from rolling inwardly into the feed trough at the discharge port), and then the next bearing will continue to roll inwardly into the feed trough at the discharge port.

[0089] See also Figure 10-12 As shown, the feeding cylinder 55 is connected to the rear side of the loading block 51 via a mounting bracket 57 .

[0090] In this embodiment, the distance between the feed trough and the rear end surface of the loading block is relatively short, and the bearing is pushed out of the discharge port at a certain distance. The feed rod requires a certain length. Therefore, in order to ensure that the front end of the feed rod can be retracted into the through opening after the output shaft of the feed cylinder retracts, the mounting frame is set to set the feed cylinder backward away from the feed trough, so that the front end of the feed rod can be retracted into the through opening, and when the output shaft of the feed cylinder extends, the feed rod can push the bearing out of the feed trough and the discharge port.

[0091] See also Figure 11 、 12 As shown, the loading block 51 includes a rear side plate 510, a middle piece 511 and a shielding plate 512. The middle piece 511 is provided with a connecting opening facing outward. The middle piece 511 is mounted on the front side of the rear side plate 510. The shielding plate 512 is connected to the front side of the middle piece 511. The connecting opening between the shielding plate 512 and the rear side plate 510 constitutes the feeding chute 52.

[0092] The feeding component is installed on the rear side of the rear side plate 510 , and the through opening 54 is provided on the rear side plate 510 .

[0093] In this embodiment, the loading block is composed of three parts, which is convenient for assembly, maintenance and replacement, and also convenient for processing the feeding trough.

[0094] See also Figure 11 、 12As shown, there is a distance between the inner end surface of the shielding plate 512 and the inner end surface of the connecting opening, and the inner end of the shielding plate 512 and the inner end of the connecting opening form the discharge port 53.

[0095] The middle member 511 includes an upper inclined plate 513, a lower inclined plate 514, and a C-shaped plate 515. The lower inclined plate 514 is arranged parallel to and below the upper inclined plate 513. The upper inclined plate 513 and the lower inclined plate 514 are arranged downwardly and inclined from the outside to the inside. The outer end of the C-shaped plate 515 is provided with a C-shaped opening 516. The inner ends of the upper inclined plate 513 and the lower inclined plate 514 are connected to the outer end surface of the C-shaped plate 515, and the distance between the upper inclined plate 513 and the lower inclined plate 514 is arranged to correspond to the C-shaped opening 516.

[0096] The shielding plate 512 is installed on the front side surfaces of the upper inclined plate 513 and the lower inclined plate 514. The inner end surface of the shielding plate 512 is flush with the inner end surfaces of the upper inclined plate 513 and the lower inclined plate 514. The front end of the C-shaped opening 516 constitutes the discharge port 53.

[0097] In this embodiment, the middle piece is composed of three parts, which is convenient for manufacturing and processing and reduces material consumption.

[0098] See also Figure 10 As shown, a material blocking component is also provided, which includes a material blocking cylinder 520 and a material blocking plate 521. A material blocking slider 522 is placed on the top surface of the loading block 51, and the material blocking cylinder 520 is installed on the top surface of the loading block 51. The output shaft of the material blocking cylinder 520 is connected to the material blocking slider 522, and the material blocking plate 521 is arranged on the front side of the loading block 51, and the top rear side of the material blocking plate 521 is connected to the front end of the material blocking slider 522; when the output shaft of the material blocking cylinder 520 is retracted, the material blocking plate 521 is arranged in the discharge port 53, and when the output shaft of the material blocking cylinder 520 is extended, the material blocking plate 521 is moved and arranged next to the discharge port 53.

[0099] In this embodiment, the material blocking plate is located at the inner end of the shielding plate, which is located at the front side of the C-shaped plate.

[0100] In this embodiment, when the bearing is in the feed trough, the axis of the bearing is parallel to the feed rod. Therefore, when the bearing rolls inward to the feed trough at the discharge port, the bearing may fall out of the discharge port. Therefore, in order to ensure that each bearing does not fall out of the discharge port when it rolls inward to the feed trough at the discharge port, a blocking component is also provided. When the bearing rolls inward to the feed trough at the discharge port, the output shaft of the blocking cylinder retracts, driving the blocking slider and the blocking plate to move outward, so that the blocking plate is in the discharge port, and it will rest on the baffle plate and can also be limited by the baffle plate. At this time, when the bearing rolls inward to the feed trough at the discharge port, the bearing will be blocked by the blocking plate and will not fall out of the feed trough. When the feed rod needs to push the bearing out of the inner end of the feed trough and onto the bearing press-fitting mechanism, the output shaft of the stopper cylinder extends, driving the stopper plate to move inward and away from the discharge port. Then the feed component sends the bearing from the feed trough and the discharge port into the bearing press-fitting mechanism, and this cycle continues to ensure the stability of the bearing feeding. In the utility model, after the bearing press-fitting mechanism receives the bearing, the axis of the bearing will be perpendicular to the axis of the motor rotor. Therefore, the bearing press-fitting mechanism can also be flipped 90 degrees so that the bearing and the motor rotor are coaxial, so as to ensure that the bearing press-fitting mechanism can smoothly, quickly and stably press-fit the bearing onto the motor rotor.

[0101] See also Figure 10-12 As shown, a material support plate 523 is further provided at the rear side of the outer end of the feeding trough 52 , and the front end of the material support plate 523 is connected to the loading block 51 .

[0102] A plurality of V-shaped brackets 524 are spaced apart on the material support plate 523 . The plurality of V-shaped brackets 524 are spaced apart from front to back, and the V-shaped brackets 524 are in communication with the outer top of the feeding trough 52 .

[0103] In this embodiment, the top of the outer end of the shielding plate is opposite the V-shaped bracket. In this way, multiple bearings can be placed in each V-shaped bracket from front to back, with the bearing axis parallel to the extension direction of the V-shaped bracket. The material support plate can be tilted downward from back to front and automatically slide forward by gravity, so that the bearing at the front end of the V-shaped bracket falls into the feed trough (the width of the feed trough is slightly larger than the thickness of a bearing. Therefore, at most only one bearing in each V-shaped bracket can move forward and fall into the feed trough at a time. The feed trough at the front end of the material support plate can also be stacked from bottom to top, with the excess bearings still in the V-shaped bracket. Alternatively, a lifting component, such as a spring or cylinder, is set at the rear end of the V-shaped bracket to push the bearing forward so that the bearings fall into the feed trough one by one. In this way, the top space is minimized and the space on both sides of the extension direction of the discharge portion is sufficient. Corresponding mechanisms can be set on both sides of the motor rotor conveying direction to facilitate the press-fitting of the motor rotor bearings and the arrangement of other motor rotor assembly mechanisms.

[0104] See also Figure 1 、 2 As shown, the discharge portion 3 includes a front discharge portion 32 and a rear discharge portion 33 with a groove 31 in the middle, and the top surfaces of the front discharge portion 32 and the rear discharge portion 33 are inclined downward from front to rear;

[0105] An intermediate connecting portion 34 having a groove 31 in the middle is further provided between the front end discharge portion 32 and the rear end discharge portion 33. The top surface of the intermediate connecting portion 34 is tilted downward from front to rear. The front end of the intermediate connecting portion 34 contacts the rear end of the front end discharge portion 32, and the rear end of the intermediate connecting portion 34 contacts the front end of the rear end discharge portion 33. The grooves of the front end discharge portion, the rear end discharge portion, and the intermediate connecting portion are connected.

[0106] A front end of the groove of the middle connecting portion 34 is provided with a front side limiting plate 35 , and a front end of the groove of the rear end discharge portion 33 is provided with a rear side limiting plate 36 .

[0107] A front lifting mechanism 37 is provided at the rear end of the groove of the front end discharge part 32, and the front lifting mechanism 37 is arranged close to the front limit plate 35; a rear lifting mechanism 38 is provided at the rear end of the groove of the middle connecting part 34, and the rear lifting mechanism 38 is arranged close to the rear limit plate 36.

[0108] In this embodiment, the groove is provided to allow the middle portion of the motor rotor to make way, and the shafts at both ends of the motor rotor are located on the top surface of the corresponding discharge portion or connection portion, and are transported backward through the inclined top surface. When the retaining spring is installed, the two ends will abut against the front end surface of the middle connection portion, and the middle portion will abut against the front limit plate. After the retaining spring is installed, the front lifting mechanism lifts it up, pushing the motor rotor to roll backward onto the middle connection portion. When the middle portion abuts against the rear limit plate and the two ends abut against the front end surface of the rear discharge portion, the two ends of the motor rotor face the bearing positioning portions on both sides, allowing the bearings on both sides to be directly pressed onto the motor rotor. After the bearings are pressed, the rear lifting mechanism lifts the motor rotor, allowing it to pass through the rear limit plate and be located on the rear discharge portion, rolling backward.

[0109] Among them, the front jacking mechanism and the rear jacking mechanism both adopt a combination of a jacking cylinder and a jacking block. The output shaft at the top of the jacking cylinder is connected to the jacking block, and the top surface of the jacking block is tilted downward from front to rear. Therefore, when the jacking cylinder drives the jacking block to move upward, the motor rotor will be pushed upward through the jacking block. When its height is above the front end of the middle connecting part, or above the front end of the rear end discharge part, the motor rotor will rotate backward and fall onto the middle connecting part or the rear end discharge part, thereby realizing automatic backward conveying of the motor rotor.
