Description

Technical Field

[0001] This application relates to the field of mechanical assembly, and in particular to an assembly device for an electric motor. Background Technology

[0002] In the motor manufacturing industry, motor assembly and production is a crucial link, and its efficiency and quality directly affect the overall performance and market competitiveness of the motor.

[0003] Currently, in some motor assembly processes, there are two main conventional methods for fitting gears into the motor's rotating shaft. One method relies entirely on manual operation, with workers manually fitting the gears completely into the motor's rotating shaft. However, the resistance when fitting the gears into the motor's rotating shaft is high, and while manually fitting the gears completely into the shaft is simple and direct, it requires a high level of skill from the workers and is physically demanding. The other method involves manually fitting the gears partially into the motor's rotating shaft, and then using a cylinder to press the gears further, ensuring they are fully fitted into the shaft. This combination of manual and cylinder pressing reduces the physical labor intensity to some extent, but still requires manual intervention.

[0004] However, these existing conventional methods have obvious drawbacks. Due to the lack of an automatic gear-adding mechanism, the entire process of fitting the gear onto the motor's rotating shaft requires manual intervention, which greatly affects production efficiency and cannot meet the demands of large-scale, high-efficiency production. Summary of the Invention

[0005] To improve production efficiency, this application provides an assembly apparatus for electric motors.

[0006] This application provides an assembly device for an electric motor, which adopts the following technical solution: An assembly device for an electric motor includes a workbench. A conveying trough and a conveying mechanism are fixedly installed on the top side of the workbench. The conveying mechanism drives the motor to move along the conveying trough. A support base is installed on the top side of the conveying trough. The support base has a sliding opening. A placement block is slidably disposed inside the sliding opening. The placement block has a placement opening. Multiple support blocks are fixedly installed inside the placement opening. The support block is elastic. A feeding pipe and a sliding mechanism are fixedly installed on the support base. The sliding mechanism drives the placement block to slide along the sliding opening. Gears are placed inside both the feeding pipe and the placement opening. A pressing mechanism is installed on the conveying trough. The pressing mechanism presses the gear inside the placement opening into the rotating shaft of the motor.

[0007] By adopting the above technical solution, the sliding mechanism drives the placement block to move, aligning the placement opening with the feeding pipe. This facilitates the gear inside the feeding pipe falling into the placement opening. The support ring supports the gear, preventing it from falling out of the placement opening automatically. After the gear falls into the placement opening, the sliding mechanism moves the placement block to offset the placement opening from the feeding pipe. Then, the conveying mechanism drives the motor to move along the conveying trough. When the motor moves below the placement opening, the pressing mechanism presses the gear inside the placement opening into the motor's rotating shaft, achieving automatic gear addition and insertion, reducing manual intervention, and improving production efficiency.

[0008] Optionally, the pressing mechanism includes a first support frame, a second support frame, a first pressing cylinder, and a second pressing cylinder. The first and second support frames are both fixedly installed on the conveying trough. The cylinder body of the first pressing cylinder is fixedly installed on the first support frame, and the cylinder body of the second pressing cylinder is fixedly installed on the second support frame. Both the first and second pressing cylinders extend and retract along the height direction. The first pressing cylinder, the feeding pipe, and the second pressing cylinder are arranged sequentially along the conveying direction of the conveying trough.

[0009] By adopting the above technical solution, the first pressing cylinder presses the gear into the rotating shaft of the motor from the placement port. At this time, the gear is not fully fitted into the rotating shaft of the motor. Then, the conveying mechanism sends the motor under the second pressing cylinder, which presses the gear again to fully fit into the rotating shaft of the motor. The gear is pressed into place in two stages, which can reduce the occurrence of local stress concentration and heat generation.

[0010] Optionally, the conveying trough is provided with a first support plate and a second support plate. A connecting rod is fixedly installed between the first support plate and the bottom side of the conveying trough. A support opening for the second support plate to enter is provided on the bottom side of the conveying trough. A limit frame is fixedly installed on the periphery of the second support plate. The limit frame abuts against the bottom side of the conveying trough. The top surface of the second support plate is flush with the inner bottom wall of the conveying trough. The second support plate is located below the support base. A support rod is fixedly installed on the bottom surface of the second support plate. A telescopic groove is provided on the top surface of the first support plate for the support rod to slide through. A lifting spring is connected between the inner bottom wall of the telescopic groove and the support rod. The lifting spring is used to drive the support rod to rise.

[0011] By adopting the above technical solution, when the pressing mechanism presses the gear into the rotating shaft of the motor, the second support plate can support the motor. If the gear and the motor rotating shaft are misaligned, the gear will press against the motor, and the motor will press against the second support plate. The second support plate can avoid this, preventing the gear and motor from being damaged by mutual compression.

[0012] Optionally, support rods are installed at all four corners of the second support plate, a pressure sensor is fixedly installed at the bottom of the telescopic groove, the lifting spring is installed between the pressure sensor and the support rod, a laser sensor is embedded in the second support plate, and when the sliding mechanism drives the placement block to move so that the placement opening is above the laser sensor, the laser sensor irradiates along the central axis of the placement opening.

[0013] By adopting the above technical solution, a second support plate with a limiting frame is set on the bottom side of the conveying trough. The support rod is raised by the lifting spring, which can provide support when the motor moves to the bottom of the support seat. Support rods are installed at the four corners of the second support plate and pressure sensors are set at the bottom of the telescopic trough to detect the pressure of the motor on the second support plate. A laser sensor is embedded in the second support plate. When the placement port is above the laser sensor, it is irradiated along the central axis of the placement port to detect the position of the gear in the placement port. This realizes the monitoring of the position and status of the motor and gear, which facilitates the subsequent gear insertion operation and improves the accuracy and efficiency of assembly.

[0014] Optionally, the conveying mechanism includes a linear module, a sliding seat, a first cylinder, a conveying plate, and multiple first infrared sensors. The linear module is fixedly installed on the worktable, and the sliding seat is fixedly installed on the linear module. The linear module is used to drive the sliding seat to move along the length direction of the conveying trough. The conveying plate is slidably installed on the sliding seat. The cylinder body of the first cylinder is fixedly connected to the sliding seat, and the piston rod of the first cylinder is connected to the conveying plate. The first cylinder extends and retracts along the width direction of the conveying trough. Multiple conveying ports are opened on the side of the conveying plate away from the first cylinder. The conveying ports are used for the motor to enter. The first infrared sensors are arranged one-to-one with the conveying ports. The first infrared sensors are fixedly installed on the bottom side of the sliding seat and are used to detect whether the motor enters the conveying port.

[0015] By adopting the above technical solution, the linear module drives the sliding seat to move along the length direction of the conveying trough, the first cylinder drives the conveying plate to extend and retract along the width direction of the conveying trough, and the conveying port on the conveying plate is used for the motor to enter. With the cooperation of the first infrared sensor to detect whether the motor enters the conveying port, the automatic conveying of the motor on the conveying trough can be realized, improving the accuracy and efficiency of motor conveying, and thus improving the production efficiency of the entire motor assembly device.

[0016] Optionally, the sliding mechanism includes a sliding spring and a second cylinder. The cylinder body of the second cylinder is fixedly installed on one side of the support base, and the piston rod of the second cylinder abuts against the placement block. The sliding spring is fixedly installed on the inner wall of the sliding port away from the second cylinder. The sliding spring abuts against the placement block and is used to drive the placement block to move towards the second cylinder. The second cylinder is used to drive the placement block to move towards the sliding spring.

[0017] By adopting the above technical solution, the sliding mechanism composed of the sliding spring and the second cylinder can drive the placement block to move along the sliding port, so that the placement port is aligned with or staggered with the feeding pipe, which facilitates the gear in the feeding pipe to fall into the placement port. After the gear falls in, the placement port can be staggered with the feeding pipe. In conjunction with the conveying mechanism and the pressing mechanism, the gear can be automatically added and fitted into the motor rotating shaft, reducing manual intervention and improving production efficiency.

[0018] Optionally, the support base is fixedly installed with multiple limiting strips, which are arranged sequentially along the length of the sliding opening. A first limiting block and a second limiting block are fixedly installed on the top side of the placement block. The top sides of both the first and second limiting blocks are higher than the limiting strips. The first limiting block is located on the side of the second limiting block away from the sliding spring. A second infrared sensor is fixedly installed on the side of the support base away from the second cylinder. The second infrared sensor is used to detect whether the second limiting block is in position.

[0019] By adopting the above technical solution, the limiting strip can limit the first limiting block and the second limiting block to ensure the accuracy of the position of the placement block during the sliding process; the second infrared sensor can detect whether the second limiting block is in place, so as to achieve accurate monitoring of the position of the placement block.

[0020] Optionally, the placement opening is provided with two arc plates inside, and the inner wall of the placement opening is provided with a hidden groove for hiding the arc plates. The arc plates are fixedly connected to a sliding rod, and the bottom of the hidden groove is provided with a sliding groove for the sliding rod to slide through. The sliding rod is equipped with a driving mechanism, which is used to drive the sliding rod to slide inside the sliding groove.

[0021] By adopting the above technical solution, the placement opening is generally slightly larger than the gear, which makes it easier for the gear to fall into the placement opening from the feeding pipe. However, this may cause the gear to be slightly misaligned with the motor's rotating shaft inside the placement opening. The drive mechanism can drive two arc plates to squeeze the gear inside the placement opening, so that the gear is centered inside the placement opening, which makes it easier for the gear to be aligned with the motor's rotating shaft.

[0022] Optionally, the driving mechanism includes a return spring, a driving block, a connecting plate, and a pressure rod. The return spring is fixedly installed between the bottom of the chute and the slide rod, and is used to drive the slide rod to retract into the chute. The top side of the placement block has a movable opening, which communicates with the placement opening. The driving block is fixedly connected to the body of the slide rod and is located inside the movable opening. The connecting plate is connected to the pressing mechanism. The pressure rod is fixedly installed on the bottom side of the connecting plate and is used to press the driving block away from the return spring. The inner walls of the slide rod and the placement opening both have clearance openings to avoid the pressure rod.

[0023] By adopting the above technical solution, the reset spring can drive the slide bar to retract into the slide groove, so as not to affect the gear falling in when the gear is placed in the placement port. The pressure rod squeezes the drive block to make the slide bar slide in the slide groove, which can drive the arc plate to extend from the hidden groove to further position and support the gear, ensuring that the pressing mechanism accurately presses the gear into the motor rotating shaft.

[0024] Optionally, a first protrusion is fixedly installed on the side of the drive block near the reset spring, and a second protrusion is fixedly installed on the side of the pressure rod away from the reset spring. Both the first and second protrusions are hemispherical, and the pressure rod and the drive block are pressed against each other by the first and second protrusions.

[0025] By adopting the above technical solution and setting hemispherical first and second protrusions, the pressure can be transmitted more smoothly when the pressure rod and the drive block squeeze each other, reducing wear and jamming, ensuring that the drive block moves smoothly in the movable opening, and thus enabling the arc plate to move normally in the placement opening. In conjunction with the overall device, the gear is automatically added and fitted into the motor rotating shaft, reducing manual intervention and improving production efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The sliding mechanism drives the placement block to move so that the placement port is aligned with the feeding pipe, which makes it easier for the gear in the feeding pipe to fall into the placement port. The support ring supports the gear to reduce the possibility of it falling off automatically. The sliding mechanism drives the placement block to move so that the placement port is misaligned with the feeding pipe. When the conveying mechanism drives the motor to move below the placement port, the pressing mechanism presses the gear into the motor rotating shaft, realizing automatic addition and insertion of the gear, reducing manual intervention. 2. The conveying trough is equipped with a first support plate and a second support plate. The second support plate can rise under the action of the lifting spring, which can support the motor. When the gear and the motor rotating shaft are misaligned, the second support plate can squeeze the lifting spring to descend and avoid the misalignment, thereby reducing the occurrence of damage caused by the gear and the motor squeezing each other.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0030] Example 1 This application discloses an assembly apparatus for an electric motor.

[0031] Reference Figure 1 , Figure 2 , Figure 3 An assembly device for an electric motor includes a workbench 1, on the top side of which a conveying trough 2 and a conveying mechanism 4 are fixedly mounted. The conveying mechanism 4 includes a linear module 41, a sliding seat 42, a first cylinder 43, a conveying plate 44, and a plurality of first infrared sensors 45.

[0032] Reference Figure 2 , Figure 3A linear module 41 is fixedly installed on the workbench 1, and a sliding seat 42 is fixedly installed on the linear module 41. The linear module 41 is used to drive the sliding seat 42 to move along the length direction of the conveying trough 2. A conveying plate 44 is slidably installed on the sliding seat 42. The cylinder body of the first cylinder 43 is fixedly connected to the top side of the sliding seat 42, and the piston rod of the first cylinder 43 is connected to the conveying plate 44. The first cylinder 43 extends and retracts along the width direction of the conveying trough 2. Multiple conveying ports 3 are opened on the side of the conveying plate 44 away from the first cylinder 43. A first infrared sensor 45 is set one-to-one with the conveying port 3, and the first infrared sensor 45 is fixedly installed on the bottom side of the sliding seat 42.

[0033] Motor assembly lines typically have a controller to manage the entire production line. In this application, the first infrared sensor 45 is electrically connected to the controller, which controls the conveyor mechanism 4 based on the detection signals from the first infrared sensor 45. After the motor assembly process in the upstream production stage is completed, the motor is fed into the conveyor trough 2. After the first infrared sensor 45 detects that the motor has been placed in the conveyor trough 2, the controller controls the conveyor mechanism 4 to operate based on the signal detected by the first infrared sensor 45.

[0034] Reference Figure 2 , Figure 3 When the conveying mechanism 4 is working, the first cylinder 43 pushes the conveying plate 44 towards the conveying trough 2, thereby allowing the motor to enter the conveying port 3. Then, the linear module 41 drives the sliding seat 42 to move along the length of the conveying trough 2, thereby driving the motor to move along the length of the conveying trough 2. After the motor reaches its position, the first cylinder 43 drives the conveying plate 44 away from the conveying trough 2, thereby removing the motor from the conveying port 3. Then, the linear module 41 drives the sliding seat 42 to reset. By repeatedly opening and closing the conveying mechanism 4, the motor enters different conveying ports 3 until the motor moves out from the end of the conveying trough 2.

[0035] Reference Figure 1 , Figure 4 A support base 5 is installed on the top side of the conveying trough 2, and the support base 5 has a sliding opening 6. A placement block 7 is slidably disposed inside the sliding opening 6. Multiple limiting strips 8 are fixedly installed on the support base 5 by bolts, and the multiple limiting strips 8 are arranged sequentially along the length of the sliding opening 6. The sliding opening 6 divides the support base 5 into two parts. The lower edge of the inner wall of the sliding opening 6 protrudes to support the placement block 7 and prevent the placement block 7 from falling. The limiting strips 8 limit the placement block 7 from above to prevent the placement block 7 from being removed from above. When it is necessary to replace the placement block 7, the limiting strips 8 are removed, and then the placement block 7 can be removed from the sliding opening 6 for replacement.

[0036] Reference Figure 4 , Figure 5The placement block 7 has a placement opening 9. Multiple support blocks 10 are fixedly installed inside the placement opening 9. Each support block 10 is hemispherical and elastic. After the gear is placed into the placement opening 9, the support blocks 10 support the gear, thereby reducing the possibility of the gear falling out of the placement opening 9 without pressure. Simultaneously, when the support blocks 10 support the gear, the top side of the gear is flush with the top side of the placement block 7, thus ensuring that only one gear can be accommodated inside the placement opening 9.

[0037] Reference Figure 4 , Figure 5 The support base 5 is fixedly equipped with a feeding pipe 11 and a sliding mechanism 12. The feeding pipe 11 is used to store gears, and the sliding mechanism 12 drives the placement block 7 to slide inside the sliding port 6. When the sliding mechanism 12 moves the placement block 7 to align the placement port 9 with the feeding pipe 11, the gear inside the feeding pipe 11 falls into the placement port 9. Then, the sliding mechanism 12 moves the placement block 7 to offset the placement port 9 from the feeding pipe 11, thereby facilitating the addition of gears into the placement port 9.

[0038] Reference Figure 4 , Figure 5 The sliding mechanism 12 includes a sliding spring 121 and a second cylinder 122. The cylinder body of the second cylinder 122 is fixedly mounted on one side of the support base 5, and the piston rod of the second cylinder 122 enters the sliding port 6 and abuts against the placement block 7. By installing a rubber block on the piston rod of the second cylinder 122, the piston rod of the second cylinder 122 is elastically abutted against the placement block 7. The sliding spring 121 is fixedly mounted on the inner wall of the sliding port 6 away from the end of the second cylinder 122, and the sliding spring 121 abuts against the placement block 7.

[0039] The piston rod of the second cylinder 122 extends, thereby pushing the placement block 7 to move along the sliding port 6, so that the feeding pipe 11 is misaligned with the placement port 9. The piston rod of the second cylinder 122 retracts, and the sliding spring 121 pushes the placement block 7 to move towards the second cylinder 122, thereby aligning the feeding pipe 11 with the placement port 9, thus facilitating the gear to fall from the feeding pipe 11 into the placement port 9.

[0040] Reference Figure 4 , Figure 5 A first limiting block 13 and a second limiting block 14 are fixedly installed on the top side of the placement block 7. The top sides of both the first limiting block 13 and the second limiting block 14 are higher than the limiting strip 8. The first limiting block 13 is located on the side of the second limiting block 14 away from the sliding spring 121. A second infrared sensor is fixedly installed on the side of the support base 5 away from the second cylinder 122. The second infrared sensor is used to detect whether the second limiting block 14 has reached its position. The second infrared sensor is electrically connected to the controller, and the controller controls the second cylinder 122 based on the detection of the second infrared sensor. The top side of the second limiting block 14 is tapered, which facilitates the positioning of the second infrared sensor.

[0041] When the second cylinder 122 pushes the placement block 7 towards the sliding spring 121, the first limiting block 13 abuts against the limiting strip 8 furthest from the sliding spring 121. When the sliding spring 121 pushes the placement block 7 towards the second cylinder 122, the second limiting block 14 abuts against the limiting strip 8 furthest from the second cylinder 122. The first limiting block 13, the second limiting block 14, and the limiting strip 8 work together to achieve a positioning function, thereby improving the accuracy of the sliding of the placement block 7.

[0042] Reference Figure 1 , Figure 4 The conveying trough 2 is equipped with a pressing mechanism 15, which includes a first support frame 151, a second support frame 152, a first pressing cylinder 153, and a second pressing cylinder 154. Both the first support frame 151 and the second support frame 152 are fixedly installed on the side of the conveying trough 2 away from the linear module 41. The cylinder body of the first pressing cylinder 153 is fixedly installed on the first support frame 151, and the cylinder body of the second pressing cylinder 154 is fixedly installed on the second support frame 152. Both the first pressing cylinder 153 and the second pressing cylinder 154 extend and retract along the height direction. The first pressing cylinder 153, the feeding pipe 11, and the second pressing cylinder 154 are arranged sequentially along the conveying direction of the conveying trough 2.

[0043] The first pressing cylinder 153 presses the gear into the rotating shaft of the motor through the placement port 9, but the gear is not fully engaged with the rotating shaft. Then, when the motor moves below the second pressing cylinder 154, the second pressing cylinder 154 presses the gear again, thus fully engaging the gear with the rotating shaft. By pressing the gear into the rotating shaft of the motor in two stages, the occurrence of localized stress concentration and overheating is reduced.

[0044] The implementation principle of the motor assembly device in this application embodiment is as follows: The motor assembled on the production line is placed at the beginning of the conveying trough 2, and the conveying mechanism 4 drives the motor to move along the conveying trough 2. When the motor moves below the placement port 9, the first pressing cylinder 153 presses down, thereby causing the gear to move out of the placement port 9 and be fitted onto the rotating shaft of the motor. Then the conveying mechanism 4 drives the motor to move below the second pressing cylinder 154, and the second pressing cylinder 154 presses the gear again, thereby completing the assembly of the gear and the motor.

[0045] Example 2 This application discloses an assembly apparatus for an electric motor.

[0046] Reference Figure 6 , Figure 7The difference between the motor assembly device of this application embodiment and Embodiment 1 is that the conveying trough 2 is provided with a first support plate 16 and a second support plate 17, and a connecting rod 18 is fixedly installed between the first support plate 16 and the bottom side of the conveying trough 2. A support opening 19 is opened on the bottom side of the conveying trough 2 for the second support plate 17 to enter, and a limiting frame 20 is fixedly installed on the periphery of the second support plate 17. The limiting frame 20 abuts against the bottom side of the conveying trough 2, and the top surface of the second support plate 17 is flush with the inner bottom wall of the conveying trough 2.

[0047] The second support plate 17 is located below the support base 5. Support rods 21 are fixedly installed at each of the four corners of the second support plate 17. The top surface of the first support plate 16 has a telescopic groove 22 for the support rods 21 to slide through. A pressure sensor 23 is fixedly installed on the inner bottom wall of the telescopic groove 22. A lifting spring connects the pressure sensor 23 to the support rod 21, and the lifting spring is used to drive the support rod 21 upwards. A laser sensor 24 is embedded in the second support plate 17. When the sliding mechanism 12 drives the placement block 7 to move so that the placement opening 9 is above the laser sensor 24, the laser sensor 24 irradiates along the central axis of the placement opening 9. Both the pressure sensor 23 and the laser sensor 24 are connected to the controller.

[0048] Reference Figure 6 , Figure 7 Initially, the motor is placed on the second support plate 17, aligning its rotation axis with the central axis of the placement port 9. The signals collected by each pressure sensor 23 are then recorded to form the first pressure signal. During production, the laser sensor 24 illuminates the central axis of the placement port 9. If there is an error in the sliding of the placement block 7, the laser sensor 24 will illuminate the gear, triggering an alarm for adjustment. If the placement block 7 slides accurately, the motor is positioned on the second support plate 17 when the conveying mechanism 4 delivers it below the placement port 9. The signals from the pressure sensors 23 are then collected to form the second pressure signal. The first and second pressure signals are compared one by one to determine if they exceed a preset pressure threshold. If so, the motor's offset is too large, requiring a shutdown for adjustment; otherwise, the motor's rotation axis is aligned with the central axis of the placement port 9.

[0049] Reference Figure 8 , Figure 9 , Figure 10The placement opening 9 has two arc plates 25 inside, and the inner wall of the placement opening 9 has a concealed groove 26 for hiding the arc plates 25. A sliding rod 27 is fixedly connected to the arc plate 25, and the bottom of the concealed groove 26 has a sliding groove 28 for the sliding rod 27 to slide through. A drive mechanism 29 is installed on the sliding rod 27, which includes a return spring 291, a drive block 292, a connecting plate 293, and a pressure rod 294. The return spring 291 is fixedly installed between the bottom of the sliding groove 28 and the sliding rod 27, and is used to drive the sliding rod 27 to retract into the sliding groove 28. A movable opening 30 is provided on the top side of the placement block 7, and the movable opening 30 communicates with the placement opening 9. The drive block 292 is fixedly connected to the body of the slide rod 27 and located inside the movable opening 30. The connecting plate 293 is fixedly connected to the piston rod of the first pressure cylinder. The pressure rod 294 is fixedly installed on the bottom side of the connecting plate 293. The pressure rod 294 is used to press the drive block 292 away from the return spring 291. Both the slide rod 27 and the inner wall of the placement opening 9 are provided with clearance openings 31 to avoid the pressure rod 294.

[0050] Reference Figure 10 , Figure 11 A first protrusion 32 is fixedly installed on the side of the drive block 292 near the return spring 291, and a second protrusion 33 is fixedly installed on the side of the pressure rod 294 away from the return spring 291. Both the first protrusion 32 and the second protrusion 33 are hemispherical, and the first protrusion 32 is elastic. The pressure rod 294 and the drive block 292 are pressed against each other by the first protrusion 32 and the second protrusion 33.

[0051] The implementation principle of the motor assembly device in this application embodiment is as follows: Generally, for convenience, the inner diameter of the feeding pipe 11 and the inner diameter of the placement port 9 are slightly larger than the gear, thus facilitating the addition of the gear. However, this also causes the gear to deviate, affecting the subsequent pressing of the gear into the rotating shaft of the motor by the first pressing cylinder 153. Therefore, in this application, when the first pressing cylinder 153 is activated, the connecting plate 293 drives the pressing rod 294 to descend. The pressing rod 294 presses the driving block 292 through the first protrusion 32 and the second protrusion 33, causing the sliding rod 27 to drive the arc plate 25 to extend out of the hidden groove 26, further positioning and fixing the gear in the placement port 9, improving the accuracy of pressing the gear into the rotating shaft of the motor. Furthermore, before the gear is pressed in, the first protrusion 32 and the second protrusion 33 separate, thereby causing the return spring 291 to cause the sliding rod 27 to drive the arc plate 25 back into the hidden groove 26, facilitating the pressing of the gear into the rotating shaft of the motor by the first pressing cylinder 153. This structural design enhances the device's ability to position gears, improves assembly accuracy and quality, reduces assembly failures caused by gear position deviations, and further improves the device's performance and reliability.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
