Description
Technical Field
[0001] This utility model relates to the field of bearing assembly technology, and in particular to a bearing assembly device for DC motor production. Background Technology
[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy through the principle of electromagnetic induction. In the production process, each component is often manufactured and processed separately, and then assembled. Since motors usually drive output components to rotate, bearings need to be installed inside the motor during the processing.
[0003] Currently, most motor bearing assembly processes use hydraulic rods to move sleeves. However, due to the variety of motor models and sizes, motor bearings also vary in size. Therefore, appropriate sleeves are often required during bearing assembly to prevent damage to the bearings when they are installed on the motor. However, existing bearing assembly devices often have sleeves that are firmly fixed and difficult to disassemble, limiting their ability to assemble bearings of a single size and thus making the devices highly restrictive.
[0004] Therefore, it is necessary to provide a bearing assembly device for DC motor production to solve the above-mentioned technical problems. Utility Model Content

At the same time, the bearing assembly position can be conveniently adjusted according to the size of the DC motor, so that it can assemble motor bearings of different sizes, which improves the practicality of the device.
[0032] The drive assembly includes an electro-hydraulic rod 15 fixedly installed on one side of the mounting plate 2. The telescopic end of the electro-hydraulic rod 15 is fixedly connected to one side of the extrusion frame 3. Through the setting of the drive assembly, the extrusion frame 3, the fixed block and the extrusion ring 16 and other structures can be moved synchronously to extrude the bearing and make it assemble with the DC motor.

The extrusion ring 16 is fixedly connected to the annular cylinder 8, and one end of the guide sleeve 17 is movably connected to the inside of the annular cylinder 8. A second spring 18 is fixedly connected to one side of the inner wall of the annular cylinder 8, and the other side of the second spring 18 is fixedly connected to the guide sleeve 17. Through the coordinated use of the extrusion frame 3, the clearance groove 5, the annular cylinder 8, the guide sleeve 17, and the second spring 18, the bearing to be assembled can be sleeved on the outer surface of the guide sleeve 17. In the subsequent assembly process, under the action of the electro-hydraulic rod 15, when the extrusion ring 16 pushes the bearing to move synchronously, the bearing is guided and limited, so that its smooth horizontal movement corresponds to the output end of the DC motor, thereby improving the quality of the motor bearing assembly.
[0034] A slot 19 is provided through the top of the processing table 1. A support frame 20 is fixedly connected inside the slot 19. A placement plate 27 is provided inside the slot 19. A sliding groove 21 is provided on the top of the placement plate 27. A guide groove 26 is provided on the front of the support frame 20. The placement plate 27 is slidably connected to the support frame 20 through the guide groove 26. With the setting of the sliding groove 21 and the guide groove 26, the sliding groove 21 can limit the two clamping plates 25, so that they can move horizontally relative to each other or apart. The setting of the guide groove 26 can guide and limit the placement plate 27, improving its stability of vertical movement.
[0035] The adjustable clamping assembly includes an electric push rod 22, a bidirectional screw 23, and a drive motor 24. The electric push rod 22 is fixedly installed on the top of the support frame 20, and its telescopic end is fixedly connected to the bottom of the placement plate 27. The bidirectional screw 23 is rotatably connected inside the slide groove 21, and two clamping plates 25 are threadedly connected to the outer surface of the bidirectional screw 23. Both clamping plates 25 are slidably connected to the slide groove 21. The drive motor 24 is fixedly installed on the front of the placement plate 27, and its output end is fixedly connected to one end of the bidirectional screw 23. By adjusting the settings of the clamping assembly, it is possible to clamp and fix DC motors of different sizes to be assembled. After clamping and fixing them, the position of their output ends can be adjusted to be positioned in the corresponding position of the placed bearing, which facilitates subsequent assembly work.
[0036] Working principle: When in use, according to the size of the bearing to be assembled, when replacing the corresponding guide sleeve 17 and extrusion ring 16, manually pull the fixing rod 13 to move it towards the front of the processing table 1 and separate it from the moving block 10 and the mounting block 4, releasing the extrusion on the moving block 10. Under the elastic force of the spring-14, the moving block 10 drives the rubber block 12 to move upward, thereby releasing the extrusion and fixing of the connecting block 7. The connecting block 7, annular cylinder 8, guide sleeve 17 and extrusion ring 16 can be disassembled simultaneously and removed through the clearance groove 5. At the same time, after replacing the guide sleeve 17 and extrusion ring 16 of the corresponding size, insert the connecting block 7 on the guide sleeve 17 and extrusion ring 16 into the connecting groove 6, and insert the fixing rod 13 into the mounting block 4. Under the action of the inclined groove 11, it extrudes the moving block 10, and the spring-14 is stretched, causing the rubber block 12 to move downward and abut against the top of the newly inserted connecting block 7, thus extruding and fixing it.
[0037] After changing the size of the guide sleeve 17 and the extrusion ring 16, the inner ring of the bearing to be assembled is placed on the outer surface of the corresponding guide sleeve 17. The guide sleeve 17 can limit its position and make it vertical. Then, the DC motor of the bearing to be assembled is placed on the placement plate 27. The drive motor 24 is started, which drives the bidirectional screw 23 to rotate. With the cooperation of the slide groove 21, the two clamping plates 25 move relative to each other, which can clamp and fix the placed DC motor. Then, according to the position of the bearing to be assembled at the output end of the DC motor, it can be adjusted up and down. That is, the electric push rod 22 is started, which extends or retracts its telescopic end. With the cooperation of the support frame 20 and the guide groove 26, the placement plate 27, the drive motor 24, the bidirectional screw 23 and the clamped DC motor can be moved up and down, which can adjust the position of the bearing to be assembled to match the placed bearing.
[0038] After adjusting the assembly height of the DC motor, start the electric hydraulic rod 15, which extends its telescopic end to drive the extrusion frame 3, mounting block 4, connecting block 7, annular cylinder 8, guide sleeve 17, extrusion ring 16, and the placed bearing to move synchronously. During the movement, the guide sleeve 17 first abuts against the output end of the DC motor and is squeezed into the annular cylinder 8, causing the spring 18 to be squeezed. The extrusion frame 3, mounting block 4, and extrusion ring 16 continue to move, and the moving extrusion ring 16 pushes the bearing sleeved on the outer surface of the guide sleeve 17 to move, so that the bearing abuts against the output end of the DC motor. Then, the continuing to move extrusion ring 16 squeezes it to assemble it with the DC motor.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
