Description

Technical Field

[0001] This utility model relates to an automatic assembly mechanism for a brushed motor commutator, belonging to the field of motor assembly and production technology. Background Technology

[0002] In the production process of brushed motor rotors, the commutator assembly is an indispensable component of the motor, responsible for current conversion and motor direction control. It not only ensures the basic functions of the motor but also largely determines its performance and reliability. The commutator assembly process typically involves the simultaneous assembly of the core, central shaft, insulating sleeve, bushing clamps, and commutator. Traditionally, a single production line is used, with separate equipment for central shaft pressing, insulating sleeve pressing, bushing clamp assembly, and commutator assembly. These components are assembled sequentially, with each assembly step connected by conveyor belts or by parts boxing and transport. This results in relatively low overall production efficiency for motor rotor assembly, a large number of machines, a large footprint, and high investment costs.

[0003] Therefore, there is an urgent need for equipment that can assemble iron cores, central shafts, insulating sleeves, bushing plates, and commutators in an integrated manner to improve assembly efficiency, save floor space, and reduce equipment investment costs. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide an automatic assembly mechanism for brushed motor commutators that can integrate and assemble the rotor core, central shaft, insulating sleeve, bushing pressure plate, and commutator of a brushed motor. Only one set of equipment is needed to complete the assembly of each part, which has high assembly efficiency, small footprint, and low equipment investment cost.

[0005] The purpose of this utility model is achieved as follows:

[0006] An automatic assembly mechanism for a brushed motor commutator includes a worktable, control cabinets and iron core feeding mechanisms located on the left and right sides of the front end of the worktable, a conveyor belt located on the rear side of the rear end of the worktable, and a central shaft pressing mechanism, an insulation plate pressing mechanism, a bushing pressing plate assembly mechanism, and a commutator pressing mechanism arranged sequentially from front to back on the worktable.

[0007] A gripper A is provided between the iron core feeding mechanism and the central shaft pressing mechanism to clamp the iron core from the iron core feeding mechanism to the central shaft pressing mechanism, and the central shaft pressing mechanism presses the central shaft into the iron core.

[0008] Between the central shaft pressing mechanism, the insulation plate pressing mechanism, the bushing pressing plate assembly mechanism, and the commutator pressing mechanism, a transfer mechanism is set up. The first transfer gripper, the second transfer gripper, the third transfer gripper, and the fourth transfer gripper on the transfer mechanism are used to transport the iron core for pressing the insulation plate, the bushing pressing plate, and the commutator.

[0009] A conveyor belt gripper is installed between the commutator pressing mechanism and the conveyor belt to clamp the assembled rotor core onto the conveyor belt.

[0010] Furthermore, the iron core feeding mechanism includes a translation mechanism and a pushing cylinder. The translation mechanism moves the entire row of iron cores as a whole, and the pushing cylinder pushes the entire row of iron cores one by one to the feeding port, which is located below the gripper A.

[0011] Furthermore, the central shaft pressing mechanism includes a central shaft feeding mechanism, gripper B, a central shaft fixture, a core fixture A, and a central shaft servo press; gripper B picks up the central shaft from the central shaft feeding mechanism and places it into the central shaft fixture, gripper A picks up the core from the core feeding mechanism and places it into the core fixture A, and the central shaft servo press drives the central shaft fixture to press the central shaft into the core, thus completing the central shaft pressing.

[0012] Furthermore, the insulation board pressing mechanism includes a right insulation board feeding mechanism and a left insulation board feeding mechanism respectively located on the left and right sides of the worktable, a left insulation board pressing mechanism and a right insulation board pressing mechanism symmetrically arranged on the worktable, and a core angle positioning mechanism; the right insulation board feeding mechanism and the left insulation board feeding mechanism continuously feed the left and right insulation boards to the left insulation board pressing mechanism and the right insulation board pressing mechanism; the first transfer gripper clamps the core with the pressed central shaft and moves it to the core angle positioning mechanism to adjust the core angle, and then the second transfer gripper continues to clamp and feed it to the left insulation board pressing mechanism and the right insulation board pressing mechanism to press the right and left insulation boards onto the left and right sides of the core, thus completing the insulation board pressing.

[0013] Furthermore, the bushing pressing plate assembly mechanism includes a bushing pressing plate feeding mechanism, a transition mechanism, a positioning and rotating mechanism, and a bushing pressing plate pressing mechanism, all mounted on a worktable. The third gripper picks up the iron core with the assembled insulation board and places it on the positioning and rotating mechanism. The rotating cylinder of the positioning and rotating mechanism rotates the iron core so that its correct pressing surface faces the bushing pressing plate pressing mechanism. The transition mechanism picks up the bushing pressing plate sent from the bushing pressing plate feeding mechanism, and the fourth gripper sends the bushing pressing plate to the bushing pressing plate pressing mechanism, which then presses it onto the central shaft of the iron core, completing the bushing pressing plate pressing.

[0014] Furthermore, the commutator pressing mechanism includes a commutator feeding mechanism, grippers C, a commutator fixture, a core fixture B, and a commutator servo press. Grippers C pick up the commutator conveyed by the commutator feeding mechanism and deliver it to the commutator fixture. The fourth gripper picks up the core with the bushing clamping plate already installed and places it in the core fixture B. The commutator servo press then presses the commutator from the commutator fixture into the central shaft of the core, completing the commutator pressing.

[0015] Furthermore, the workbench is equipped with a waste trough A and a waste trough B, which are used to store defective products of the central shaft press-fitting and defective products of the commutator press-fitting, respectively.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This utility model integrates a central shaft pressing mechanism, an insulating plate pressing mechanism, a bushing pressing plate assembly mechanism, and a commutator pressing mechanism, which are sequentially installed on a workbench. The pressing workpieces are transferred and transported between these mechanisms by multiple sets of grippers, forming an integrated set of equipment. Only one set of equipment is needed to efficiently complete the pressing of the iron core central shaft, insulating plate, bushing pressing plate, and commutator, reducing intermediate material transfer links, and achieving fully automatic assembly. The overall pressing efficiency is high, the footprint is small, and the equipment investment cost is low. Attached Figure Description

[0031] See Figures 1-9 This utility model relates to an automatic assembly mechanism for a brushed motor commutator, comprising a workbench 1, control cabinets 2 and a core feeding mechanism 3 located on the left and right sides of the front end of the workbench 1, a conveyor belt 8 located on the rear side of the rear end of the workbench 1, and a central shaft pressing mechanism 4, an insulation plate pressing mechanism 5, a bushing pressing plate assembly mechanism 6, and a commutator pressing mechanism 7 arranged sequentially from front to back on the workbench 1; the workbench 1 is provided with a waste trough A12 and a waste trough B13, which are used to store defective central shaft pressing products and defective commutator pressing products, respectively;

[0032] The iron core feeding mechanism 3 includes a translation mechanism 31 and a pushing cylinder 32. The translation mechanism 31 translates the entire row of iron cores as a whole, and the pushing cylinder 32 pushes the entire row of iron cores one by one to the feeding port 33. A gripper A9 is provided between the iron core feeding mechanism 3 and the central shaft pressing mechanism 4. The feeding port 33 is located below the gripper A9. The gripper A9 clamps and feeds the iron core from the iron core feeding mechanism 3 to the central shaft pressing mechanism 4, and the central shaft pressing mechanism 4 presses the central shaft into the iron core.

[0033] The central shaft pressing mechanism 4 includes a central shaft feeding mechanism 41, a gripper B42, a central shaft fixture 43, a core fixture A44, and a central shaft servo press 45. The gripper B42 picks up the central shaft from the central shaft feeding mechanism 41 and places it into the central shaft fixture 43. The gripper A9 picks up the core from the core feeding mechanism 3 and places it into the core fixture A44. The central shaft servo press 45 drives the central shaft fixture 43 to press the central shaft into the core, thus completing the central shaft pressing. Cores that fail the central shaft pressing are placed in the scrap trough A12 by the gripper A9.

[0034] Between the central shaft pressing mechanism 4, the insulation plate pressing mechanism 5, the bushing pressing plate assembly mechanism 6, and the commutator pressing mechanism 7, a transfer mechanism 10 is set up. The first transfer gripper 101, the second transfer gripper 102, the third transfer gripper 103, and the fourth transfer gripper 104 on the transfer mechanism 10 are used to transport the iron core for pressing the insulation plate, bushing pressing plate, and commutator. After the iron core completes the central shaft pressing, it is picked up and transferred between the subsequent pressing mechanisms by the transfer grippers of the transfer mechanism 10.

[0035] The insulating plate pressing mechanism 5 includes a right insulating plate feeding mechanism 51 and a left insulating plate feeding mechanism 52 respectively disposed on the left and right sides of the workbench 1, a left insulating plate pressing mechanism 53 and a right insulating plate pressing mechanism 54 symmetrically disposed on the workbench 1, and a core angle positioning mechanism 55; the left and right insulating plates are continuously fed by the right insulating plate feeding mechanism 51 and the left insulating plate feeding mechanism 52, and the left and right insulating plates are clamped and sent to the left insulating plate pressing mechanism 53 and the right insulating plate pressing mechanism 54 by the third transfer gripper 103; the first transfer gripper 101 clamps the core with the center shaft already pressed and sends it to the core angle positioning mechanism 55 to adjust the core angle, and then the second transfer gripper 102 continues to clamp and send it to the left insulating plate pressing mechanism 53 and the right insulating plate pressing mechanism 54 to press the right and left insulating plates to the left and right sides of the core, thus completing the insulating plate pressing;

[0036] The bushing pressing plate assembly mechanism 6 includes a bushing pressing plate feeding mechanism 61, a transition mechanism 62, a positioning and rotating mechanism 63, and a bushing pressing plate pressing mechanism 64, all mounted on the worktable 1. The third gripper 103 picks up the iron core with the assembled insulation plate and places it on the positioning and rotating mechanism 63. The rotating cylinder of the positioning and rotating mechanism 63 rotates the iron core so that its correct pressing surface faces the bushing pressing plate pressing mechanism 64. The transition mechanism 62 picks up the bushing pressing plate sent from the bushing pressing plate feeding mechanism 61, and the fourth gripper 104 sends the bushing pressing plate to the bushing pressing plate pressing mechanism 64, where it is pressed into the central shaft of the iron core, thus completing the bushing pressing plate pressing.

[0037] The commutator pressing mechanism 7 includes a commutator feeding mechanism 71, a gripper C72, a commutator fixture 73, a core fixture B74, and a commutator servo press 75. The gripper C72 picks up the commutator conveyed by the commutator feeding mechanism 71 and sends it to the commutator fixture 73. The fourth gripper 104 picks up the core with the bushing clamping plate installed and places it in the core fixture B74. The commutator servo press 75 presses the commutator in the commutator fixture 73 into the central shaft of the core, thus completing the commutator pressing.

[0038] A conveyor belt gripper 11 is provided between the commutator pressing mechanism 7 and the conveyor belt 8 to clamp the assembled rotor core to the conveyor belt 8, which then transports it to the next production process. If a commutator pressing defective product is found, it is placed in the waste trough B13.

[0039] This utility model integrates all the main pressing mechanisms onto a single workbench 1, and controls them uniformly and collaboratively from a control cabinet 2. This combines multiple traditional, scattered pressing devices into a single integrated device. The iron cores fed one by one by the iron core feeding mechanism 3 are clamped by grippers A9 and sent to the central shaft pressing mechanism 4 for central pressing. Then, through multiple transfer grippers of the transfer mechanism 10, the iron cores are sequentially pressed into the insulation plate pressing mechanism 5, the bushing pressing plate assembly mechanism 6, and the commutator pressing mechanism 7 to complete the pressing of the insulation plate, bushing pressing plate, and commutator. Finally, the conveyor belt grippers 11 clamp the iron cores that have completed the commutator pressing and send them to the conveyor belt 8 for transport to the next production process.

[0040] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
