Description

Technical Field

[0001] This invention relates to the field of motor equipment technology, specifically to a motor assembly device. Background Technology

[0002] An AC motor is a machine used to convert mechanical energy into alternating current (AC) electrical energy. Due to the rapid development of AC power systems, AC motors have become the most commonly used type of motor. Compared to DC motors, AC motors lack a commutator (see commutation in DC motors), resulting in a simpler structure, easier manufacturing, greater robustness, and ease of production into high-speed, high-voltage, high-current, and high-capacity motors. However, assembling AC motors often presents the following problems: because AC motors are generally larger, it is difficult to manually align the mounting holes on the end caps (front and rear end caps) with the motor housing, making effective installation challenging.

[0003] A method for assembling an AC motor disclosed in Chinese invention patent application CN112186997B, although it solves the problem that AC motors are generally large and difficult to align the mounting holes of the sealing cap and the motor housing manually by centering the other end of the motor housing through structural design, still suffers from the disadvantage of low mechanization.

[0018] The first conveying component 5 is used to transport the rotor 14, sequentially transporting the rotor 14 to the rear bearing component 3 and the rear end cover component 6; the rear bearing component 3 is used to assemble the rear bearing inner cover and the rear bearing at the rear end of the rotor 14 shaft; the front bearing component 4 is used to assemble the front bearing inner cover and the front bearing at the front end of the rotor 14 shaft; the rear end cover component 6 is used to assemble the rear end cover 16 at the rear end of the rotor 14 shaft; the rear bearing cover component 7 is used to assemble the rear bearing cover at the rear end of the rotor 14 shaft; the first gripping component 8 is used to grip, lift, move, and horizontally move the rotor 14, and sequentially move the rotor 14 to the position of the rear end cover component 6, the rear bearing cover component 7, and the end of the first gripping component 8 away from the first conveying component 5; The second gripping component 9 is used to grip and move the motor housing 15, and move the motor housing 15 sequentially to the end of the second gripping component 9 near the end of the first gripping component 8, the front cover component 10, and the front bearing cover component 11. The rotor 14 and the motor housing 15 are assembled at the end of the second gripping component 9 near the end of the first gripping component 8. The third conveying component 13 is used to transport the motor housing 15 and transport it to the position below the second gripping component 9. The front cover component 10 is used to assemble the front cover 17 on the front end of the rotor 14 shaft. The front bearing cover component 11 is used to assemble the front bearing cover on the front end of the rotor 14 shaft. The second conveying component 12 is used to transport the assembled rotor 14 and motor housing 15 away from the equipment as a whole.

[0019] The first conveying component 5 is used to transport the rotor (including the shaft, rotor core, and rotor windings). The front bearing component 4 and the rear bearing component 3 have the same structural features and functions, and are arranged opposite each other on both sides of the first conveying component 5. The front bearing component 4 is used to install the front bearing inner cover and the front bearing on the rotor shaft, and the rear bearing component 3 is used to install the rear bearing inner cover and the rear bearing on the rotor shaft. The first gripping component 8 is used to grip and lift the rotor (adjusting and raising the rotor height). At the same time, the first gripping component 8 is also used to adjust the horizontal position of the rotor 14, thus achieving horizontal displacement. The rear end cover component 6 is used to install the rear end cover 16 on the rear end of the rotor shaft. The rear bearing cover component 7 is used to install the rear bearing cover on the rotor shaft (at this time, the rotor has already had the rear end cover 16 installed), and the rear bearing cover serves to fix the rear end cover 16.

[0020] The third conveying component 13 is used to transport the motor housing 15 (at this time, the motor housing has already been equipped with the motor stator, which includes the stator core and stator windings). The second gripping component 9 is used to grip and lift the motor housing 15 (adjusting the height of the rotor), and also to adjust the horizontal position of the rotor 14, thus achieving horizontal displacement. The first gripping component 8 and the second gripping component 9 have the same structural features and functions, and are arranged side by side (their slide rails are in a horizontally corresponding state). The coordinated movement of the first gripping component 8 and the second gripping component 9 can achieve the function of installing the rotor 14 into the motor housing 15, that is, inserting the rotor 14 into the motor housing 15. The front cover component 10 is used to install the front cover 17 on the motor housing 15 (at this time, the rotor 14, the rear cover 16, etc. have already been installed on the motor housing 15). The front bearing cover component 11 is used to install the front bearing cover on the motor housing 15 (at this time, the rotor 14, the rear cover 16, the front cover 17, etc. have already been installed on the motor housing 15), and the front bearing cover is used to fix the front cover 17.

[0021] The controller contains a logic control program (software) used to control the start and stop of the vacuum generator and each motor, thereby completing the mechanical work in each step. The vacuum generator uses vacuum pressure as its power source to generate air pressure control for each cylinder, that is, it uses the vacuum generator to control the movement of each cylinder.

[0022] In practice, the assembly sequence of the various parts of the motor is as follows: (i) Rotor (including shaft, rotor core and rotor winding); (ii) (1) Front bearing inner cover - front bearing, (2) Rear bearing inner cover - rear bearing; (iii) Rear bearing end cover; (iv) Rear bearing cover; (v) Motor housing (the stator is assembled inside the motor housing, and the stator includes stator core and stator winding); (vi) Front end cover; (vii) Front bearing cover. Among them, the assembly of (1) front bearing inner cover - front bearing and (2) rear bearing inner cover - rear bearing is carried out simultaneously.

[0023] The rear bearing component 3 includes a rear bearing inner cover box 3001, a rear bearing box 3002, a first support cylinder 3003, a first ball screw 3004, a first sliding cylinder 3005, a first clamping cylinder 3006, a second clamping cylinder 3007, and a first drive motor. The first drive motor and the first ball screw 3004 are both located inside the first support cylinder 3003. The output shaft of the first drive motor is connected to the first ball screw 3004. The sliding block of the first ball screw 3004 is fixedly connected to one end of the first sliding cylinder 3005. The first clamping cylinder 3006 and the second clamping cylinder 3007 are located at the other end of the first sliding cylinder 3005.

[0024] The system comprises a first drive motor that drives a first ball screw 3004. When driven, the sliding block of the first ball screw 3004 drives a first sliding cylinder 3005 to move vertically (up and down). Simultaneously, the first gripping cylinder 3006 and the second gripping cylinder 3007, located on the first sliding cylinder 3005, can move vertically. The first sliding cylinder 3005 also enables the first gripping cylinder 3006 and the second gripping cylinder 3007, located on its sliding block, to move horizontally. The first gripping cylinder 3006 grips the inner cover of the rear bearing in the rear bearing inner cover box 3001, and the second gripping cylinder 3007 grips the rear bearing in the rear bearing box 3002. In implementation, the system utilizes the logic programs of a controller and a vacuum generator to control the start and stop of the first drive motor, the movement of the sliding block of the first sliding cylinder 3005, and the gripping cylinders 3006 and 3007 to perform gripping and releasing. During this process, the first clamping cylinder 3006 and the second clamping cylinder 3007 simultaneously and respectively grasp the rear bearing inner cover and the rear bearing. Then, the first ball screw 3004 drives the first sliding cylinder 3005 to move upward as a whole. Then, the sliding block of the first sliding cylinder 3005 drives the first clamping cylinder 3006 and the second clamping cylinder 3007 to move away from the first ball screw 3004. During the movement, the rear bearing inner cover and the rear bearing are fitted onto the rear end of the rotor shaft, thus completing the assembly of the rear bearing inner cover and the rear bearing.

[0025] The front bearing component 4 includes a front bearing inner cover box 4001 and a front bearing box 4002. The front bearing inner cover box 4001 is used to hold the front bearing inner cover, and the front bearing box 4002 is used to hold the front bearing. The structural features and technical principles of the front bearing component 4 are consistent with those of the rear bearing component 3, and the front bearing component 4 also includes all the technical features shown in the rear bearing component 3. In implementation, the front bearing component 4 can be fitted onto the front end of the rotor shaft, thus completing the assembly of the front bearing inner cover and the front bearing.

[0026] The first gripping component 8 includes a first servo motor 8001 and a first hanging plate 8002. A slide rail (which can be a ball screw) is mounted on the first hanging plate 8002. The first servo motor 8001 is connected to the slide rail. A first electric cylinder 8003 is mounted on the slide rail. A rotating assembly 8004 is fixedly mounted on the output shaft end of the first electric cylinder 8003. A third gripping cylinder 8005 is fixedly mounted below the rotating assembly 8004. The third gripping cylinder 8005 is used to grip the rotor. The rotating assembly 8004 is used to adjust the horizontal angle position of the rotor by rotation. The first electric cylinder 8003 is used to adjust the height position of the rotor by extension and retraction. The first servo motor 8001 drives the first electric cylinder 8003 to move horizontally on the slide rail.

[0027] The rear cover component 6 includes a rear cover support groove plate 6001 and two sets of lifting components disposed on the side wall of the rear cover support groove plate 6001. The lifting components include a single-shaft cylinder 6002, a lifting cylinder 6003 and a clamping member 6004. The output shaft end of the single-shaft cylinder 6002 is fixedly connected to the outer side wall of the lifting cylinder 6003, and the clamping member 6004 is fixedly disposed on the output shaft end of the lifting cylinder 6003. The single-shaft cylinder 6002 is used to drive the lifting cylinder 6003 to generate displacement. During the displacement process, the clamping member 6004 located at the output shaft end of the lifting cylinder 6003 can hold the edge of the rear end cover 16. Under the combined action of the two clamping members 6004, the rear end cover 16 can be clamped and fixed. After the clamping member 6004 clamps and fixes the rear end cover 16, the output shaft end of the lifting cylinder 6003 extends and retracts, causing the rear end cover 16 to move. During the process of the rear end cover 16 being pushed out by the output shaft of the lifting cylinder 6003, the center hole of the rear end cover 16 is fitted onto the rotor shaft, thus completing the assembly of the rear end cover 16. The lifting cylinder 6003 can be an electric cylinder.

[0028] The second gripping component 9 has the same structural features and function as the first gripping component 8 (please refer to the first gripping component 8 above for the structural features and working principle of the second gripping component 9). The two are arranged side by side (the slide rails of the two are in a horizontally corresponding state). The cooperative movement of the first gripping component 8 and the second gripping component 9 can play the role of installing the rotor 14 into the motor housing 15, that is, inserting the rotor 14 into the motor housing 15.

[0029] The front cover component 10 is used to install the front cover 17 on the motor housing 15 (at this time, the rotor 14, the rear cover 16, etc. have already been installed on the motor housing 15). The front cover component 10 and the rear cover component 6 have the same working principle and structural features (the specific assembly process of the front cover 17 is the same as the assembly process of the rear cover component 6).

[0030] The front bearing cover component 11 includes a front bearing cover box 1101, a second support cylinder 1102, a second ball screw 1103, a fourth clamping cylinder 1104, a second sliding cylinder 1105, and a second drive motor. Both the second drive motor and the second ball screw 1103 are housed within the second support cylinder 1102. The second drive motor is connected to the second ball screw 1103 via a transmission connection. The sliding block of the second ball screw 1103 is fixedly connected to one end of the second sliding cylinder 1105, and the other end of the second sliding cylinder 1105 is threadedly connected to the fourth clamping cylinder 1104. The front bearing cover component 11 is used to install the front bearing cover on the motor housing 15 (on which the rotor 14, rear end cover 16, and front end cover 17 have already been installed). The front bearing cover is used to fix the front end cover 17. The second drive motor drives the second ball screw 1103, and the sliding block of the second ball screw 1103 moves up and down, which in turn drives the second sliding cylinder 1105 to move up and down. Under the control of the vacuum generator, the sliding block of the second sliding cylinder 1105 can move, and the fourth clamping cylinder 1104 located on the sliding block of the second sliding cylinder 1105 moves along the second sliding cylinder 1105. The fourth clamping cylinder 1104 is used to clamp the front bearing cover inside the front bearing cover box 1101. During the movement of the fourth clamping cylinder 1104 along the second sliding cylinder 1105, the fourth clamping cylinder 1104 puts the front bearing cover onto the rotor shaft, thus completing the assembly of the front bearing cover.

[0031] Specifically, the controller can be a processor, including but not limited to a programmable logic controller (PLC) and a microcontroller. The vacuum generator is connected to the first sliding cylinder 3005, the first clamping cylinder 3006, the second clamping cylinder 3007, the single-axis cylinder 6002, the third clamping cylinder 8005, and the fourth clamping cylinder 1104 via air guide pipes. The controller is electrically connected to the first drive motor, the lifting cylinder 6003, the first servo motor 8001, the first electric cylinder 8003, the rotating assembly 8004, and the second drive motor. The controller internally carries a logic control program (software part) used to control the start and stop of the vacuum generator and each motor according to time nodes to complete the mechanical work of each step. The vacuum generator uses vacuum pressure as a power source to generate air pressure control for each cylinder, that is, it uses the vacuum generator to control the movement of each cylinder.

[0032] In use, the motor assembly process is as follows: the first conveying component 5 conveys the rotor to the rear bearing component 3 and the front bearing component 4. The rear bearing component 3 and the front bearing component 4 simultaneously install the rear bearing inner cover, the rear bearing, the front bearing inner cover, and the front bearing at both ends of the rotor shaft. Then, the first conveying component 5 sends the rotor (at this time, the rotor has the rear bearing inner cover, the rear bearing, the front bearing inner cover, and the front bearing installed) to the rear end cover component 6. The first gripping component 8 grips the rotor and adjusts the rotor height to make the rotor and the rear end cover component 6 have the same height. The rear end cover component 6 works to assemble the rear end cover 16 onto the rotor 14. Then, the first gripping component 8 drives the rotor to move to the rear bearing cover component 7. The rear bearing cover component 7 works to assemble the rear bearing cover onto the rotor shaft.

[0033] Subsequently, the rotating assembly 8004 of the first gripping component 8 adjusts the angular position of the rotor (causing the rotor to rotate 90 degrees), and the first gripping component 8 drives the rotor to move to one end (i.e. Figure 1 At this time, the third conveying component 13 conveys the motor housing 15 to the lower part of the second gripping component 9. The second gripping component 9 works and grips the motor housing 15. Driven by the second servo motor 9001 in the second gripping component 9, the motor housing 15 moves towards the rotor and is fitted onto one end of the rotor. The third gripping cylinder 8005 releases the rotor, the first electric cylinder 8003 retracts, and the first servo motor 8001 drives the first electric cylinder 8003 to move horizontally (away from the motor housing 15). Then the first electric cylinder 8003 extends, and the first servo motor 8001 drives the first electric cylinder 8003 to move horizontally (towards the motor housing 15). During the movement, the third gripping cylinder 8005 touches the rotor (specifically, touches the rear end cover 16), so that the rotor 14 is inserted into the motor housing 15 as a whole, thus completing the assembly of the rotor 14 and the motor housing 15.

[0034] Subsequently, driven by the first servo motor 8001 of the second gripping component 9, the motor housing 15 (which has already been assembled with the rotor and related parts) moves to the front cover component 10. The front cover component 10 operates and assembles the front cover 17 onto the rotor shaft. Then, the second gripping component 9 places the motor housing 15 onto the second conveying component 12. When the second conveying component 12 moves the motor housing 15 to the front bearing cover component 11, the front bearing cover component 11 operates and assembles the front bearing cover onto the rotor shaft.

[0035] In the specific implementation of this technical solution for motor assembly, other components can be added to assist in the motor assembly work. For example, screw components can be added to tighten screws on various parts in the motor assembly process, as some parts need to be fastened with screws during the motor assembly process.
