Description

Technical Field

[0001] The invention relates to the field of mechanical processing equipment, in particular to an automatic assembly device for a motor rotor commutator. Background Art

[0002] The motor rotor refers to the rotating part of the motor. Together with the stator, it constitutes the motor and realizes the conversion between electrical energy and mechanical energy. Depending on the application type, the motor rotor can be divided into an electric motor rotor and a generator rotor. In addition, according to the different rotation methods, the motor rotor can also be divided into an inner rotor rotation method and an outer rotor rotation method. The inner rotor rotation method refers to the core in the middle of the motor as the rotating body, while the outer rotor rotation method refers to the outer body of the motor as the rotating body;

[0003] When the motor rotor is being processed, a steering gear needs to be installed on its outside to control the direction of the motor when the motor is running. When the motor is running normally, the steering gear will automatically switch so that the motor can run in different directions. In some specific application scenarios, the steering gear can also be used to control the speed and torque of the motor.

[0004] The current commutator installation device is mainly composed of a vibration plate and a conveying device. The conveying device installs the commutator on the vibration plate onto the rotor. During the assembly process, the rotor will be displaced due to the vibration generated by transportation. When the device drives it to load again, the displaced rotor will affect the subsequent assembly, thereby delaying the processing speed. Summary of the invention

[0055] Embodiment 2

[0056] The difference between this embodiment and the first embodiment is that:

[0057] The side of the limit plate 84 close to the commutator disc is designed as an inclined surface, and a soft pad is embedded in the end of the limit plate 84 close to the baffle 82. The limit plate 84 improves the pushing effect on the commutator disc through the cooperation of the inclined surface and the soft pad, avoiding conflict with the commutator disc.

[0061] Embodiment 3

[0062] The difference between this embodiment and the first and second embodiments is that:

[0063] A triangular block 88 is mounted on the top of the top arm 87 , and one end of the triangular block 88 facing the discharge arm 74 is cut, so that the triangular block 88 is convenient for the discharge arm 74 to drive it.

[0064] When the discharging arm 74 rotates, the triangular block 88 may be pushed down by the discharging arm 74 , thereby driving the triangular block 88 to move inside the hollow sleeve 86 to generate kinetic energy.

[0065] The end of the second piston rod 811 away from the limiting plate 81 is equipped with a push plate 812, and a rubber plate is embedded on the outside of the push plate 812, and anti-slip grooves are provided on the outside of the rubber plate. The push plate 812 facilitates the second piston rod 811 to drive the workpiece, and the anti-slip grooves improve the stability when driving the workpiece.

[0066] When the push plate 812 pushes the workpiece, it can contact the workpiece through the external rubber plate, and then avoid scratches and wear between the workpiece through the ability of deformation.

[0067] A feeding trough is provided on the upper end surface of the feeding guide rail 36, and the output end of the feeding cylinder 35 is slidably disposed inside the feeding trough, so that the feeding trough facilitates the movement of materials.

[0068] The upper end surface of the support device 1 is equipped with a discharge track platform 11, and the top of the support device 1 is equipped with a limiting low-position plate 12. A slot is opened at one end of the limiting low-position plate 12 close to the discharge arm 74. The discharge track platform 11 facilitates the discharge of materials. The limiting low-position plate 12 can limit the movement of the commutator disk so that the commutator disk can support the workpiece. At the same time, the slot facilitates the fixing base 83 and the triangular block 88 to be pressed down and driven by the discharge arm 74.

[0069] Working principles of the main structural parts in this scheme:

[0070] Support device 1: It is the basic structure of the whole device, supports and connects other components, provides a stable assembly platform, and ensures the relative position and movement accuracy between components;

[0071] Pneumatic triplex 2: Provides driving force and controls the pneumatic equipment inside the device. It is the power source of the device and ensures the normal operation of each pneumatic component.

[0072] Loading device 3: The storage part 31 stores the workpieces, and the feeding part 33 and the feeding guide 36 cooperate with the feeding cylinder 35 to deliver the workpieces to the designated position, which is used to realize automatic loading of the workpieces and improve production efficiency. When working, the workpieces are stored in the storage part 31, and through the cooperation of the feeding part 33 and the feeding guide 36, and the push of the feeding cylinder 35, the workpieces are accurately delivered to the designated position. This step ensures the continuous supply of workpieces and provides a basis for subsequent assembly work;

[0073] Control module 4: operates and controls the components inside the device through electronic control, thereby ensuring that the entire device operates according to the predetermined program;

[0074] Pushing device 5: The pushing cylinder 52 cooperates with the transmission cylinder 53 and the pneumatic clamp 54 to transfer the workpiece from the feeding device to the transfer device 7, thereby realizing the precise transfer of the workpiece and ensuring the accuracy of assembly. When the workpiece is sent to the specified position, the pushing cylinder 52 cooperates with the transmission cylinder 53 and the pneumatic clamp 54 to move and transfer the workpiece from the feeding device to the limit device 8 of the transfer device 7. This step ensures the stability and accuracy of the workpiece during the assembly process;

[0075] Pressing device 6: The additional pressing cylinder 64 drives the track slider 62 to descend, and then processes the workpiece by pushing the cylinder 63, so as to realize press-fitting and processing of the workpiece, and ensure the assembly quality of the workpiece and the steering gear. When working, on the material transfer device 7, the motor 71 drives the commutator disk 72 to rotate, and the workpiece is brought to the bottom of the pressing device 6. At this time, the pressing cylinder 64 drives the track slider 62 to descend, and then press-fits and processes the workpiece by pushing the cylinder 63. This step ensures the tight connection between the workpiece and the steering gear;

[0076] Material transfer device 7: the additional motor 71 drives the commutator disk 72 to rotate, and the electric rotating rod 73 drives the discharging arm 74 to discharge the material, thereby realizing the continuous rotation and discharging of the workpiece, and improving the assembly efficiency;

[0077] Limiting device 8: The workpiece is clamped and limited by the cooperation of the additional limiting disk 81, the baffle 82 and the limiting plate 84, thereby ensuring the stability and accuracy of the workpiece during the assembly process.

[0078] Material transfer device 7 and limiting device 8: During the assembly process, the limiting device 8 automatically fixes the workpiece through the cooperation of the limiting plate 81, the baffle 82, the limiting plate 84 and the piston rod. This step avoids the deviation of the motor rotor and the steering gear due to vibration during movement, thereby ensuring the accuracy and speed of assembly.

[0079] The support base 32 added to the material storage portion 31 is used to support the material storage portion 31 to facilitate the disassembly and maintenance of the structural parts.

[0080] Transmission cylinder 53 and gear: The rotation of the pneumatic clamp 54 is achieved through the cooperation of the rack and the gear.

[0081] The guide rail groove of the track slider 62 provides guidance for the track slider 62 to ensure linear motion.

[0082] Discharging arm 74: drives the workpiece at both ends to push the material.

[0083] This solution uses a three-stage drive to push the material. After the assembly is completed, the motor 71 continues to drive the commutator disk 72 to rotate, and the workpiece is brought to the outside of the discharge arm 74. At this time, the electric rotating rod 73 drives the discharge arm 74 to move, first squeezing the top arm 87, generating airflow through the bend 89 into the inside of the hollow column 810, and then pushing the second piston rod 811 to move. At the same time, the discharge arm 74 also drives the workpiece, realizing the three-stage push of the workpiece. This step avoids the workpiece from being stuck inside the device and causing wear, and improves the discharge speed and stability of the material.

[0084] The inclined limiting plate 84 in the second embodiment of the present invention can improve the pushing effect and avoid the interference between the workpieces.

[0085] The triangular block 88 and the push plate 812 in the third embodiment are driven by the discharge arm 74 to further push the workpiece.

[0086] How this solution works:

[0087] The workpiece is stored in the storage part 31, and the workpiece is pushed into the top of the feeding guide rail 36 through the feeding part 33. The workpiece is pushed to move by the feeding cylinder 35, and the pushing cylinder 52 drives the pneumatic clamp 54 to move, and descends to grab the workpiece. When the workpiece is placed on the top of the limit plate 81, the workpiece is clamped and limited by the limit plate 81 and the baffle 82 and the limit plate 84. The motor 71 drives the commutator plate 72 and the limit plate 81 to rotate, and the workpiece moves to the bottom of the pressing device 6, and is driven by the pressing cylinder 64. The movable track slider 62 moves, and then the workpiece is processed by pushing the cylinder 63. The processed workpiece continues to be driven by the commutator disk 72 and moves to the outside of the discharge arm 74. The electric rotating rod 73 drives the discharge arm 74 to move. The discharge arm 74 first squeezes the triangular block 88, drives the top arm 87 to descend, and generates airflow to enter the interior of the hollow column 810 through the bend 89, and then pushes the push plate 812 to move, pushes the workpiece, and then cooperates with the moving discharge arm 74 to push the workpiece from the upper, middle and lower sections together, and finally discharges it through the discharge track platform 11.

[0088] The present invention adopts the above scheme and principle, and achieves the following improved effects compared with the traditional scheme:

[0089] 1. Improve the degree of automation: Through the integrated components of feeding, pushing, pressing and transferring, the device realizes the automatic assembly and connection between the motor rotor and the steering gear, greatly improving the overall degree of automation of the device.

[0090] 2. Ensure assembly accuracy: The limit device automatically fixes the workpiece during the assembly process, avoiding deviation between the motor rotor and the steering gear due to vibration during movement, thereby ensuring the accuracy and speed of assembly.

[0091] 3. Improve the discharging speed and stability: The three-stage drive pusher design avoids the workpiece getting stuck inside the device and causing wear. At the same time, the linkage between devices improves the discharging speed and stability of the material.

[0092] 4. Improve production efficiency: The entire assembly process is automated and continuous, reducing manual intervention and waiting time, thereby improving production efficiency.

[0093] 5. Reduce production costs: Automated assembly reduces labor costs and scrap rates, thus reducing production costs.
