Description

Technical Field

[0001] The present invention relates to the technical field of motor processing, and in particular to an automatic processing device for pressing a bearing into an end cover of a motor for a vehicle. Background Art

[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 motor processing process, the bearing is pressed into the motor end cover for installation. For example, Chinese patent No. CN116488417A proposes an automatic processing device for pressing bearings into motor end covers, which is highly practical and can smoothly press the bearings.

[0003] However, in practical application, this device faces several challenges. First, it's difficult to evenly distribute the oil on the bearing surface. This can cause unnecessary resistance or friction when the bearing is pressed into the motor end cap, compromising the fit and smooth operation of the bearing. Second, if the device fails to adequately vacuum the bearing before applying the oil, dust and impurities may remain on the bearing surface. These contaminants can reduce the effectiveness of the oil application. Therefore, we propose an automated processing device for pressing bearings into automotive motor end caps.

The second cylinder 17 is provided with a third connecting pipe 22 and a fourth connecting pipe 23 connected to the interior thereof, and the ends of the third connecting pipe 22 and the fourth connecting pipe 23 connected to the second cylinder 17 are both located below the second piston 35, and the end of the third connecting pipe 22 away from the second cylinder 17 is connected to the oil storage tank 13, and the end of the fourth connecting pipe 23 away from the second cylinder 17 is directed toward the bottom of the electromagnet 24.

[0022] When the present invention is used, in the initial state, 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 is located between the two clamping blocks 18, the electromagnet 24 is energized to make it magnetic, so that the bearing to be pressed in is adsorbed and fixed, and then the cylinder 9 is started 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 spring 4 , its cross plate 5 does not move downward in the initial stage, that is, the pressing plate 7 gradually approaches the cross plate 5, and the downward movement of the pressing plate 7 causes the pressing rod 15, the first round rod 14 and the bottom block 6 to move downward accordingly. During the downward movement of the pressing rod 15, since the rotating block 31 is located in the rotating groove 25, the rotating block 31 slides in the rotating groove 25, and then the rotating tube 16, the electromagnet 24 and the bearing fixed by the electromagnet 24 rotate accordingly. When the pressing plate 7 moves to abut against the top of the rotating tube 16, the rotating tube 16 rotates several circles; When the pressure plate 7 moves to the top of the rotating tube 16 and contacts it, the first round rod 14 will move downward first. The tension generated by the second tension spring 33 being pulled out can make the first piston 32 move downward gradually. The downward moving first piston 32 will produce 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 to improve the subsequent oiling effect. Since the bearing is rotating during the process of suctioning 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 retractable to cooperate with the subsequent downward movement of the pressure plate 7 and the cross plate 5. When the pressure plate 7 moves to the top of the rotating tube 16 and abuts against it, 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 and the first piston 32 are no longer in contact, and the pressure plate 7 will contact each other with the limit block 36 and cause the limit block 36 to move downward a distance. During the downward movement of the limit block 36, the second spring 30 will be compressed, and the limit 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 to the outer surface of the bearing through the fourth connecting pipe 23, so that when the subsequent bearing is pressed together, 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 on the bearing surface, the bearing rotates, so that the lubricating oil can be sprayed evenly, thereby improving the use effect. 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 are close to each other. The clamping blocks 18 close to each other can clamp and fix the motor end cover of a certain size, and then when the bearing is pressed in, the motor end cover can remain stable to ensure the pressing effect. After the pressure plate 7 is butted against the top of the rotating tube 16, the cylinder 9 is used to make 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 adsorbed by the electromagnet 24 can move downward synchronously as a whole, and 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 adsorbed bearing will not rotate, and finally the bearing is pressed into the fixed motor end cover; After the bearing is pressed into the motor end cover, the electromagnet 24 is powered off so that it no longer attracts the bearing, and the pressure plate 7 is moved upward by the cylinder 9. In the first stage, the elastic force generated by the compression of the first spring 4 can make the pressure plate 7, the first round rod 14, the cross plate 5, the rotating tube 16, the electromagnet 24 and the second cylinder 17 move upward as a whole. After the first spring 4 returns to its original length, the pressure plate 7 continues to move upward until it returns to the initial position. During this process, the pressure plate 7 gradually moves away from the cross plate 5. The elastic force generated by the compression of the second spring 30 can make the second piston 35 move upward, so that the lubricating oil in the oil storage tank 13 is sucked into the second cylinder 17 through the third connecting pipe 22, so that When lubricating the next bearing, during the upward movement of the first round rod 14, the first round rod 14 will contact the first piston 32 again and make the first piston 32 move upward. The second tension spring 33 is stretched, and the upward moving first piston 32 will squeeze the dust and impurities in the first cylinder 10 into the dust storage box 12 through the first connecting pipe 11, and the upward moving bottom block 6 will no longer contact the auxiliary block 27. The inclined surface on the bottom block 6 and the inclined surface on the auxiliary block 27 no longer cooperate with each other. The tension generated by the stretching of the first tension spring 20 can make the two clamping blocks 18 move away from each other, and then the motor end cover can be no longer fixed. At this time, the motor end cover can be removed after processing.
