Description

Technical Field

[0001] The utility model relates to the technical field of motor production, and more specifically, to a device for installing and pressing a motor sealing ring. Background Technique

[0002] In the field of motor manufacturing and application, ensuring the sealing performance of the motor is one of the key factors for ensuring the stable operation of the motor and extending its service life. For the output end of the motor, especially the seal between the rotating shaft and the housing, it is often faced with the erosion of impurities such as liquids, gases or dust in the working environment. If the seal is not tight, it will directly cause damage to the internal components of the motor and affect the overall performance of the motor. The traditional installation method of motor sealing rings mostly relies on manual operation, which is not only inefficient, but also the installation quality is greatly affected by human factors. At the same time, during the installation process of the sealing ring, due to the elasticity and hardness of the sealing ring material itself, it is often difficult to directly fit the sealing ring onto the output end of the motor, and additional tools or methods are required to achieve the widening and deformation of the sealing ring for smooth installation. However, if the operation is improper during this process, it is easy to cause damage to the sealing ring and affect the sealing effect. Therefore, we propose a device for installing and pressing a motor sealing ring to solve the above problems. Content of the Utility Model

[0025] As Figures 4 to 8As shown in the figure, in another embodiment of the present utility model, a support disk 516 is installed at the lower end of the push rod 510. An auxiliary hole 515 is provided in the middle of the lower surface of the support disk 516. A number of first movable slots 517 are provided on the outside of the support disk 516.

[0026] The feeding device transports the sealing ring to the transport rack 6, and then the user positions and installs the raw material 3 through the clamp 2. After the installation of the clamp 2 is completed, the electric slide rail 507 cooperates with the second slider 508 to move the expansion claw 519 to the upper end of the sealing ring. After the expansion claw 519 moves to the specified position, the second cylinder 509 pushes the push rod 510 and the expansion claw 519 to move downward, so that the lower end of the expansion claw 519 is stuck in the inside of the sealing ring, and then the second electric push rod 512 pulls up the pull rope 523 through the connecting plate 513 and the annular support block 514, so that the pull rope 523 is connected to the second electric push rod 512 through the movable block 522. The No. 1 fixed rod 521 pulls the expansion claw 519 to expand outward with the No. 1 fixed rod 518 as the axis, so that as the expansion claw 519 expands, the sealing ring is set on the outside of the expansion claw 519 and deforms with the expansion claw 519. Then, after the sealing ring and the expansion claw 519 are temporarily integrated, the No. 2 cylinder 509 pulls the push rod 510 and the expansion claw 519 to move upward. At the same time, the No. 2 slider 508 drives the expansion claw 519 and the sealing ring to move to the upper end of the raw material 3. Then, after moving to the specified position, the No. 2 cylinder 509 pushes the push rod 510 and the expansion claw 519 to move downward, so that the expansion claw 51 9 drives the sealing ring to be sleeved on the outer side of the rotating shaft on the raw material 3, and then after the sealing ring moves to the specified position, the No. 1 cylinder 504 controls the No. 1 electric push rod 505 and the adjusting rod 506 to be located at the upper end of the sealing ring, and then the No. 1 electric push rod 505 controls the adjusting rod 506 to move to the upper side of the sealing ring, and then after the adjusting rod 506 moves to the specified position, the No. 1 cylinder 504 can pull the adjusting rod 506 to move downward, so that the adjusting rod 506 pulls the sealing ring to move, so that the sealing ring is separated from the surface of the expansion claw 519, and restores the deformation to be stuck on the outer side of the rotating shaft, and then the No. 2 cylinder 509 pulls the expansion claw 519 to Reset, after the expansion claw 519 is reset, the sealing ring can be pulled down slowly by the No. 1 cylinder 504 and the adjustment rod 506 to gradually adjust the position of the sealing ring. At the same time, the annular electric slide rail 502 and the No. 1 slider 503 can evenly control the movement of various parts of the sealing ring. Then, after the sealing ring moves to the specified position, the No. 1 electric push rod 505 can continuously squeeze the sealing ring through the adjustment rod 506. At the same time, the annular electric slide rail 502 and the No. 1 slider 503 can also control them to move, so that they can evenly press the sealing ring to further improve the sealing performance of the sealing ring;

[0027] The support plate 524 is used to assist the pull rope 523 in moving, so as to avoid the situation where the extension claw 519 cannot be controlled to perform the extension work due to the pull rope 523 moving straight up or down;

[0028] The torsion spring is used to assist the expansion claw 519 in resetting, so that the expansion claw 519 can continuously control the sealing ring to expand and move.

[0029] The working principle of the motor sealing ring installation and clamping device:

[0030] When in use, first the loading device transports the sealing ring to the transport rack 6, and then the user positions and installs the raw material 3 through the clamp 2. After the clamp 2 is installed, the electric slide rail 507 cooperates with the second slider 508 to move the expansion claw 519 to the upper end of the sealing ring. After the expansion claw 519 moves to the specified position, the second cylinder 509 pushes the push rod 510 and the expansion claw 519 to move downward, so that the lower end of the expansion claw 519 is stuck in the inside of the sealing ring, and then the second electric push rod 512 pulls the pull rope 523 upward through the connecting plate 513 and the annular support block 514, so that the pull rope 523 passes through the movable block 522 and the second fixed rod 521 pull the expansion claw 519 to expand outward with the first fixed rod 518 as the axis, so that as the expansion claw 519 expands, the sealing ring is set on the outside of the expansion claw 519 and deforms with the expansion claw 519. Then, after the sealing ring and the expansion claw 519 are temporarily integrated, the second cylinder 509 pulls the push rod 510 and the expansion claw 519 to move upward. At the same time, the second slider 508 will drive the expansion claw 519 and the sealing ring to move to the upper end of the raw material 3. Then, after moving to the specified position, the second cylinder 509 pushes the push rod 510 and the expansion claw 519 to move downward, so that the expansion claw 519 The claw 519 drives the sealing ring to be sleeved on the outer side of the rotating shaft on the raw material 3. Then, after the sealing ring moves to the specified position, the No. 1 cylinder 504 controls the No. 1 electric push rod 505 and the adjusting rod 506 to be located at the upper end of the sealing ring. Then, the No. 1 electric push rod 505 controls the adjusting rod 506 to move to the upper side of the sealing ring. Then, after the adjusting rod 506 moves to the specified position, the No. 1 cylinder 504 can pull the adjusting rod 506 downward, so that the adjusting rod 506 pulls the sealing ring to move, so that the sealing ring is separated from the surface of the expansion claw 519 and recovers its deformation to be stuck on the outer side of the rotating shaft. Then, the No. 2 cylinder 509 pulls the expansion claw 519. After the expansion claw 519 is reset, the sealing ring can be continuously pulled downward slowly by the No. 1 cylinder 504 and the adjusting rod 506 to gradually adjust the position of the sealing ring. At the same time, the annular electric slide rail 502 and the No. 1 slider 503 can evenly control the movement of various parts of the sealing ring. After the sealing ring moves to the specified position, the sealing ring can be continuously squeezed by the No. 1 electric push rod 505 through the adjusting rod 506. At the same time, the annular electric slide rail 502 and the No. 1 slider 503 can also control them to move, so that they can evenly press the sealing ring to further improve the sealing performance of the sealing ring.

For those of ordinary skill in the art, based on the above description, other different forms of changes or alterations can be made. It is impossible to list all the implementation manners here. Any obvious changes or alterations derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
