Description

Technical Field

[0001] This invention relates to the field of motor processing technology, and in particular to an automatic processing device for pressing bearings into the end caps of automotive motors. Background Technology

[0002] An electric motor, also known as a motor, is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. During the manufacturing process of an electric motor, bearings are pressed into the motor end cover for installation. For example, an automatic processing device for pressing bearings into the motor end cover is proposed in Chinese Patent No. CN116488417A, which has the characteristics of strong practicality and smooth pressing of bearings.

[0003] However, the aforementioned device faces several challenges in practical applications. First, it is difficult to achieve uniform distribution of the oil when applied to the bearing surface, which may cause unnecessary resistance or friction when the bearing is pressed into the motor end cover, thus affecting the pressing effect and the smooth operation of the bearing. Second, if the bearing is not adequately vacuumed before applying the oil, dust and impurities may remain on the bearing surface, which will reduce the coating effect of the oil. Therefore, we propose an automated processing device for pressing bearings into automotive motor end covers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an automated processing device for pressing bearings into the end caps of automotive motors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, the fixing assembly includes a base block fixedly installed below the pressure plate, a slot is provided on the cross plate, the base block passes through the slot, a fixing block is fixedly installed on the top of the base, two telescopic rods are fixedly installed on the side wall of the fixing block near the electromagnet, the telescopic ends of the two telescopic rods are fixedly connected to the same clamping block, two first tension springs are fixedly connected between the clamping block and the fixing block, an auxiliary block is fixedly installed on the side wall of the clamping block away from the electromagnet, and an auxiliary slot is provided on the top of the base directly below the base block.

[0009] Preferably, the dust collection assembly includes a first cylinder fixedly mounted on the bottom of the mounting plate, a circular hole at the bottom of the first cylinder, a first piston slidably connected to its inner wall inside the first cylinder, a second tension spring fixedly connected between the first piston and the inner bottom of the first cylinder, a first connecting pipe and a second connecting pipe communicating with the inside of the first cylinder, the ends of the first connecting pipe and the second connecting pipe communicating with the first cylinder being located above the first piston, a first circular rod fixedly mounted on the top of the pressure plate, the first circular rod being adapted to the circular hole, the end of the first connecting pipe away from the first cylinder communicating with the dust collection box, and the end of the second connecting pipe away from the first cylinder facing downwards towards the electromagnet.

[0010] Preferably, the fuel injection assembly includes a second cylinder fixedly mounted on the top of the cross plate. A second cylindrical rod is slidably connected to the top of the second cylinder. A second piston is fixedly mounted on the end of the second cylindrical rod inside the second cylinder and slidably connected to the inner wall of the second cylinder. A limit block is fixedly mounted on the end of the second cylindrical rod outside the second cylinder. A second spring is fixedly connected between the limit block and the top of the second cylinder. A third connecting pipe and a fourth connecting pipe are provided on the second cylinder and communicate with its interior. The ends of the third connecting pipe and the fourth connecting pipe that communicate with the second cylinder are both located below the second piston. The end of the third connecting pipe away from the second cylinder is connected to the fuel tank, and the end of the fourth connecting pipe away from the second cylinder faces downward towards the electromagnet.

[0014] The beneficial effects of this invention are:

[0015] By setting up a rotating component, the electromagnet and the bearing that is attracted and fixed by the electromagnet can rotate several times as the pressure plate approaches the cross plate, which facilitates subsequent dust collection and oil spraying.

[0016] By setting up a dust collection component, the bearing that is attracted and fixed by the electromagnet can be automatically dusted as the pressure plate approaches the cross plate. At the same time, the rotating component makes the bearing rotate, which can improve the dust collection effect.

[0017] By setting up an oil spraying component, the bearing surface after dust collection can be automatically sprayed with oil as the pressure plate approaches the cross plate. This provides lubrication during the subsequent pressing of the bearing, allowing it to be pressed more smoothly into the motor end cover. In conjunction with the rotating component, the lubrication can be made more uniform.

[0018] By setting up a fixing component, the motor end cover placed on the base can be automatically clamped and fixed before the bearing is pressed into the motor end cover. No manual operation of other equipment is required for fixing, making the operation simple and convenient and improving work efficiency.

[0019] This invention can automatically clamp and fix the motor end cover before the bearing is pressed into the motor end cover. This not only improves work efficiency, but also ensures the stability and accuracy of the pressing process. In addition, it integrates the dual pre-treatment functions of dust collection and oil spraying, which not only improves the efficiency and accuracy of bearing pressing operations, but also significantly improves the overall quality and reliability of the product by improving the pressing environment and lubrication conditions, thus optimizing the processing process.

[0030] Two dust collection components are provided below the mounting plate 8. The dust collection components include a first cylinder 10 fixedly installed on the bottom of the mounting plate 8.

A second tension spring 33 is fixedly connected between the first piston 32 and the inner bottom of the first cylinder 10. A first connecting pipe 11 and a second connecting pipe 21 are provided on the first cylinder 10 and communicate with its interior. The ends of the first connecting pipe 11 and the second connecting pipe 21 that communicate with the first cylinder 10 are both located above the first piston 32. A first round rod 14 is fixedly installed on the top of the pressure plate 7. The first round rod 14 is adapted to the circular hole 34. The end of the first connecting pipe 11 away from the first cylinder 10 is connected to the dust collection box 12. The end of the second connecting pipe 21 away from the first cylinder 10 faces downwards towards the electromagnet 24. One-way valves are provided on the first connecting pipe 11, the second connecting pipe 21, the third connecting pipe 22 and the fourth connecting pipe 23.

[0031] Two oil spraying assemblies are provided above the base 1. The oil spraying assembly includes a second cylinder 17 fixedly installed on the top of the cross plate 5. A second round rod 29 is slidably connected to the top of the second cylinder 17. A second piston 35 is fixedly installed at one end of the second round rod 29 inside the second cylinder 17 and slidably connected to the inner wall of the second cylinder 17. A limit block 36 is fixedly installed at the other end of the second round rod 29 outside the second cylinder 17. A second spring 30 is fixedly connected between the limit block 36 and the top of the second cylinder 17. A third connecting pipe 22 and a fourth connecting pipe 23 are provided on the second cylinder 17 and communicate with its interior. The ends of the third connecting pipe 22 and the fourth connecting pipe 23 that communicate with the second cylinder 17 are both located below the second piston 35. The end of the third connecting pipe 22 away from the second cylinder 17 is connected to the oil reservoir 13. The end of the fourth connecting pipe 23 away from the second cylinder 17 faces downwards towards the electromagnet 24.

[0032] In the initial state of use, the first round rod 14 passes through the round hole 34 and abuts against the first piston 32. The second tension spring 33 is in a stretched state. The motor end cover is placed on the base 1 and positioned between the two clamping blocks 18. The electromagnet 24 is energized to make it magnetic, thereby attracting and fixing the bearing to be pressed in. Then, the cylinder 9 is activated to move the pressure plate 7 downward. During the downward movement of the pressure plate 7, since there are two first springs 4 fixedly connected between the cross plate 5 and the base 1, the elastic force of the first springs 4... In the initial stage, the cross plate 5 will not move downward. That is, the pressure plate 7 gradually approaches the cross plate 5. The downward movement of the pressure plate 7 causes the pressure rod 15, the first round rod 14 and the bottom block 6 to move downward as well. During the downward movement of the pressure rod 15, since the rotating block 31 is located in the rotating groove 25, the rotating block 31 slides in the rotating groove 25, which in turn causes the rotating tube 16, the electromagnet 24 and the bearing attracted and fixed by the electromagnet 24 to rotate. When the pressure plate 7 moves to abut against the top of the rotating tube 16, the rotating tube 16 has rotated several times.

[0033] During the process of the pressure plate 7 moving to the top of the rotating tube 16 and abutting, the first round rod 14 will move downward first. The pulling force generated by the second tension spring 33 being pulled out can make the first piston 32 gradually move downward. The downward movement of the first piston 32 will generate a suction effect, thereby sucking the dust and impurities adhering to the bearing surface into the first cylinder 10 through the second connecting tube 21 for suction treatment, so as to improve the subsequent oiling effect. Since the bearing rotates during the suction treatment of the dust and impurities adhering to the bearing surface, the treatment can be more comprehensive. The part of the second connecting tube 21 located between the mounting plate 8 and the cross plate 5 is telescopic to cooperate with the subsequent downward movement of the pressure plate 7 and the cross plate 5.

[0034] During the process of the pressure plate 7 moving to the top of the rotating tube 16 and abutting, the second tension spring 33 will return to its original length, that is, the first piston 32 will no longer move downward, and the bearing will complete the dust collection process. At this time, as the pressure plate 7 moves downward, the first round rod 14 will no longer contact the first piston 32, and the pressure plate 7 will contact the limiting block 36 and cause the limiting block 36 to move downward a certain distance. During the downward movement of the limiting block 36, the second spring 30 will be compressed, and the limiting block 36 will drive the second round rod 29 and the second piston 35 to move downward. During the downward movement of the second piston 35, the lubricating oil in the second cylinder 17 will be sprayed onto the outer surface of the bearing through the fourth connecting pipe 23, so that when the bearing is pressed in later, it can play a lubricating role, so that the bearing can be pressed into the motor end cover more smoothly. At the same time, during the process of spraying oil onto the bearing surface, the bearing is rotating, so that the lubricating oil can be sprayed evenly and the use effect can be improved.

[0035] During the downward movement of the bottom block 6, the inclined surface on the bottom block 6 will cooperate with the inclined surface on the auxiliary block 27, thereby extending the telescopic rod 19 and pulling out the first tension spring 20, so that the two clamping blocks 18 come closer to each other. The clamping blocks 18 that come closer to each other can clamp and fix the motor end cover of a certain size, so that the motor end cover can remain stable when the bearing is pressed in, ensuring the pressing effect. After the pressure plate 7 abuts against the top of the rotating tube 16, the cylinder 9 makes the pressure plate 7 continue to move downward, so that the pressure plate 7, the first round rod 14, the cross plate 5, the rotating tube 16, the electromagnet 24, the bottom block 6, the second cylinder 17 and the bearing attracted by the electromagnet 24 can move downward synchronously. The first spring 4 is compressed. Since the rotating block 31 can no longer slide in the rotating groove 25 on the pressure rod 15, the rotating tube 16, the electromagnet 24 and the attracted bearing will not rotate, and finally the bearing is pressed into the fixed motor end cover.

[0036] After the bearing is pressed into the motor end cover, the electromagnet 24 is de-energized, preventing it from attracting the bearing. The cylinder 9 then moves the pressure plate 7 upwards. In the first stage, the compression of the first spring 4 generates a spring force that causes the pressure plate 7, the first rod 14, the cross plate 5, the rotating tube 16, the electromagnet 24, and the second cylinder 17 to move upwards as a whole. After the first spring 4 returns to its original length, the pressure plate 7 continues to move upwards until it returns to its initial position. During this process, the pressure plate 7 gradually moves away from the cross plate 5. The compression of the second spring 30 generates a spring force that causes the second piston 35 to move upwards, thereby drawing the lubricating oil in the oil reservoir 13 into the second cylinder 17 through the third connecting pipe 22. During the lubrication of the next bearing, as the first round rod 14 moves upward, it will come into contact with the first piston 32 again, causing the first piston 32 to move upward. The second tension spring 33 will be stretched, and the upward-moving first piston 32 will squeeze the dust and impurities in the first cylinder 10 into the dust collection box 12 through the first connecting pipe 11. The upward-moving bottom block 6 will no longer come into contact with the auxiliary block 27, and the inclined surface on the bottom block 6 will no longer cooperate with the inclined surface on the auxiliary block 27. The tension generated by the stretching of the first tension spring 20 can make the two clamping blocks 18 move away from each other, thereby making the motor end cover no longer fixed. At this time, the motor end cover after processing can be removed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
