[0002] As a core component of the vehicle's power system, the sealing performance of the rear bearing cover of the transmission directly affects the circulation efficiency of the lubricating oil and the service life of the drive shaft. As a key sealing element of the rear bearing cover, the oil seal needs to be pre-lubricated with grease before pressing to reduce friction and wear.

[0003] Patent publication number CN114392867B relates to a grease-applying equipment and method for pressing and applying oil seals on the rear bearing cover of a gearbox. The equipment includes a frame, guardrail, workbench, positioning device, electric servo cylinder, pressing head, servo grease application slide, electric rotary nozzle, grease metering valve, control system, workpiece identification device, pressing head monitoring device, nozzle monitoring device, pressure monitoring device, laser sensor, and grease pump station. It can automatically and precisely meter the lubrication and pressing of the oil seal stop on the rear bearing cover according to different products. It is compatible with multiple products and effectively controls the amount of grease applied, the spraying position, the pressing position, and the pressing force. It completely eliminates problems such as uneven manual grease application and oil seal pressing defects caused by contaminants from manual grease application, improving product quality and reducing the cost of lubricating grease consumables.

[0004] The shortcomings of the prior art, including the aforementioned patents, are that when the positioning block clamps workpieces of different sizes, the center of the workpiece may shift from the center of the pressing head due to operational errors and changes in friction, which may cause the pressing head to crush the workpiece when it presses it. Summary of the Invention

In slot one, a limiting slot is provided inside the worktable, and a second sliding groove is provided at the bottom of the moving end of the electric servo cylinder. The first push rod is slidably connected in the second sliding groove. The fixed frame is fixedly connected to the front and rear sides of the worktable, and the fixed end of the elastic telescopic plate is fixedly connected to the top of the fixed frame. A slot is provided on the circumferential surface of the support frame, and the moving end of the elastic telescopic plate is slidably connected in the slot. The workpiece is slidably connected to the side of the positioning blocks that are close to each other. When the center of the workpiece is consistent with the center of the pressing head, when the moving end of the electric servo cylinder moves downward, the bottom of the moving end of the electric servo cylinder will contact the sliding rod, pushing the sliding rod downward so that the sliding rod is inserted into the limiting slot, ensuring that the positioning block will not move during pressing, thus fixing and limiting the workpiece.

[0009] According to the above technical solution, a first spring is provided between the slide rod and the positioning block. The slide rod is reset by the elastic force of the first spring. The end of the push rod near the pressing head is provided with an inclined surface. The inclined surface is in contact with the slide rod, which facilitates its movement.

When the moving end of the electric lifting rod moves upward, it drives the first motor to move upward, which in turn drives the rotating rod to move upward, which in turn drives the grease spray nozzle to move upward, and the upward movement of the rotating rod also drives the flexible telescopic cleaning brush to move upward.

[0011] According to the above technical solution, the grease application mechanism also includes a grease reservoir, a pin rod, and a second triangular block. A storage groove is provided on the top of the worktable, and the grease reservoir is placed inside the storage groove. The pin rod is slidably connected in the limiting groove, and the second triangular block is fixedly connected to the top of the slide plate. When the slide plate resets, it will block the through hole inside the worktable, preventing excess grease on the inner wall of the workpiece from dripping into the bottom of the worktable from the through hole during sealing. After the slide plate blocks the through hole inside the worktable, excess grease will slide into the grease reservoir through the second triangular block on the top of the slide plate.

[0012] According to the above technical solution, a No. 3 spring is provided between the slide plate and the worktable, and the slide plate is reset by the elastic force of the No. 3 spring. A torsion spring is provided between the rotating shaft and the rotating rod, and the rotating shaft is reset by the torsion spring. A No. 4 spring is provided between the pin rod and the worktable, and the pin rod is reset by the elastic force of the No. 4 spring. A pin groove is provided at the bottom of the slide plate, and the pin rod is inserted into the pin groove to limit the slide plate. The top of the moving end of the elastic telescopic cleaning brush is provided with a slope, and the slope contacts the bottom of the worktable to push the moving end of the elastic telescopic cleaning brush into the fixed end. The front end of the moving end of the elastic telescopic cleaning brush is an arc surface, which can better contact the inner wall of the workpiece. The top of the rotating rod is provided with an arc surface, which can better push the slide plate to move. A through hole is provided in the center of the worktable, and the diameter of the through hole is larger than the diameter of the grease spray nozzle, so that the grease spray nozzle can pass through the through hole.

[0013] According to the above technical solution, the bottom of the workbench is equipped with a processing mechanism, which includes a centrifuge device, a second motor, a grease infusion tube, a funnel, a filter plate, and a scraper. The centrifuge device is located on the left side of the base. The second motor is fixedly connected to the top of the centrifuge device. The bottom end of the grease infusion tube is fixedly inserted through the top of the centrifuge device. The funnel is fixedly connected to the inner wall of the centrifuge device. The filter plate is fixedly connected inside the funnel. The scraper is fixedly connected to the output end of the second motor. The output end of the second motor rotates through the top of the centrifuge device. After the grease enters the centrifuge device, it first goes into the funnel and then passes through the filter plate to filter impurities in the grease. The filtered grease then enters the centrifuge tank inside the centrifuge device through the inclined surface at the bottom of the funnel. At the same time, the second motor is started. The rotation of the output end of the second motor drives the scraper to rotate. The rotation of the scraper scrapes the impurities on the surface of the filter plate, preventing impurities from accumulating and clogging the grease outlet at the bottom of the grease infusion tube for a long time.

The second rack slides through the bottom of the workbench. The second rack meshes with the gear. When the telescopic rod moves downward, it will drive the first rack to move downward. The downward movement of the first rack will drive the gear to rotate. The rotation of the gear will drive the second rack to move upward. The upward movement of the second rack will touch the switch of the heating plate, causing the heating plate to start heating the grease in the grease storage cylinder.

[0015] According to the above technical solution, the top of the second rack is an arc surface. By contacting the start switch of the heating plate through the arc surface, the start switch of the heating plate can be pressed more effectively. A fifth spring is provided between the first rack and the fixed block. The first rack is reset by the fifth spring.

[0016] (III) Beneficial Effects

[0017] This invention provides a press-fit grease-applying device for the oil seal of the rear bearing cover of a gearbox. It has the following beneficial effects:

[0018] (1) The invention adapts to five standard workpieces of different sizes by sliding the positioning block on the worktable surface. When the center of the workpiece is aligned with the center of the pressing head, the slide rod will be directly in front of the limiting groove on the worktable surface. When the moving end of the electric servo pressing cylinder moves downward, it will push the slide rod into the limiting groove, so that the positioning block can limit and clamp the workpiece, ensuring that the workpiece can be successfully pressed.

[0019] (2) In this invention, when the center of the workpiece is offset from the center of the pressing head, the slide rod is no longer aligned with the limiting groove. The moving end of the electric servo pressing cylinder cannot push the slide rod into the limiting groove when it moves downward. The slide rod will be inserted into the second slide groove, pushing the push rod one to move towards the elastic telescopic plate. The push rod one pushes the moving end of the elastic telescopic plate, releasing the elastic telescopic plate from the limiting position of the worktable. When the moving end of the electric servo pressing cylinder moves downward, it will push the worktable downward, thus preventing the pressing head from crushing the workpiece when it presses it.

[0020] (3) In this invention, the moving end of the electric lifting rod rises, which in turn drives the rotating rod to rise. The rising of the rotating rod will drive the elastic telescopic cleaning brush to rise. After the elastic telescopic cleaning brush passes through the through hole in the center of the worktable, it enters the interior of the workpiece. The moving end of the elastic telescopic cleaning brush will pop out the fixed end, so that the front arc surface of the moving end contacts the inner wall of the workpiece. Then, the No. 1 motor is started to drive the rotating rod to rotate. The rotation of the rotating rod drives the elastic telescopic cleaning brush to rotate, so that the elastic telescopic cleaning brush cleans the impurities on the inner wall of the workpiece, avoiding the impurities from affecting the grease coating effect of the grease spray nozzle on the inner wall of the workpiece and affecting the subsequent oil seal pressing effect.

[0021] (4) In this invention, the sliding rod moves downward, pushing the pin rod downward to release the limit on the sliding plate, so that the sliding plate blocks the through hole in the center of the worktable, preventing excess grease on the inner wall of the workpiece from dripping into the bottom of the worktable from the through hole during the oil seal pressing. At the same time, the excess grease dripping onto the top of the second triangular block after the workpiece is pressed by the oil seal is slid into the grease storage tank through the inclined surface, ensuring that the surface of the worktable is clean and preventing grease with impurities from affecting the grease coating effect of subsequent workpieces, and preventing the situation of waste grease and new grease mixing on the workpiece.

[0022] (5) In this invention, the lubricating grease collected in the grease storage tank is transported to the centrifuge device through the grease delivery pipe. After the impurities in the waste grease are filtered through the filter plate, the waste grease is reused after secondary processing in the centrifuge device. After each batch of workpieces is sealed, the moving end of the telescopic rod is pulled to make the moving end of the telescopic rod reach the bottom of the limit groove. When the pin moves downward, it will push the telescopic rod downward. The downward movement of the telescopic rod will drive the first rack to move. The movement of the first rack will drive the gear to rotate. The rotation of the gear will drive the second rack to move. The movement of the second rack will open the heating plate, so that the heating plate heats the waste lubricating grease collected in the grease storage tank, so as to prevent the lubricating grease from becoming viscous at low temperature and being unable to come to the centrifuge device normally from the grease delivery pipe. At the same time, the rotation of the gear will open the valve so that the waste lubricating grease collected in the grease storage tank can enter the grease delivery pipe. In this way, by delivering waste grease to the centrifuge device batch by batch, the amount of lubricating grease sprayed in this batch can be judged by observing the amount of waste grease in the grease storage tank, which is convenient for controlling and adjusting the grease coating of the next batch.

[0046] The top of the second rack 613 is curved, and the curved surface contacts the start switch of the heating plate 608, which can better press the start switch of the heating plate 608. A fifth spring is provided between the first rack 612 and the fixed block 611, and the first rack 612 is reset by the fifth spring.

[0047] During operation, after workpiece 7 is placed on worktable 3, the moving positioning block 403 clamps and limits workpiece 7. Once workpiece 7 is clamped, the electric servo cylinder 401 is activated, causing its moving end to move downwards. This downward movement of the electric servo cylinder 401 drives the pressing head 402 downwards, which then presses the workpiece 7 into the oil seal groove. When the center of workpiece 7 aligns with the center of the pressing head 402, the bottom of the moving end of the electric servo cylinder 401 contacts the sliding rod 404, pushing it downwards and inserting it into the limiting groove. This ensures that the positioning block 403 does not move during pressing, thus fixing and limiting workpiece 7. If the center of workpiece 7 does not align with the center of the pressing head 402, the sliding rod 404 will not move downwards. When the position of the slot is offset, the sliding rod 404 cannot be pushed downward when the moving end of the electric servo cylinder 401 moves downward. The sliding rod 404 cannot move downward, so the top of the sliding rod 404 will insert into the second sliding groove, and the arc surface of the top of the sliding rod 404 will contact the inclined surface of the push rod 405. This will push the push rod 405 towards the elastic telescopic plate 407, causing the moving end of the elastic telescopic plate 407 to move towards the fixed end. This will cause the moving end of the elastic telescopic plate 407 to leave the slot on the circumferential surface of the support frame 2, releasing the restriction on the worktable 3. The downward movement of the moving end of the electric servo cylinder 401 will push the worktable 3 downward, preventing the pressing head 402 from crushing the workpiece 7. At the same time, the force required to push the push rod 405 is greater than the force required to push the sliding rod 404 downward. When the sliding rod 404 can be pushed downward, the push rod 405 will not be pushed.

[0048] After workpiece 7 is clamped and limited by positioning block 403, electric lifting rod 501 is activated. Upon activation, the moving end of electric lifting rod 501 moves upward, which in turn drives motor 502 upward. Motor 502 then drives rotating rod 503 upward, which in turn drives grease spray nozzle 504 upward. The upward movement of rotating rod 503 also drives elastic telescopic cleaning brush 514 upward. When rotating rod 503 passes through the through hole in the center of worktable 3, the inclined surface at the top of the moving end of elastic telescopic cleaning brush 514 contacts worktable 3, pushing the moving end of elastic telescopic cleaning brush 514 into the fixed end, thus retracting the elastic telescopic cleaning brush 514 into the fixed end. 4. The rotating rod 503 can pass smoothly through the through hole. Moving the rotating rod 503 upward will cause the top arc surface to contact the first triangular block 516 at the bottom of the sliding plate 513. By contacting the inclined surface of the first triangular block 516, the sliding plate 513 is pushed away from the workpiece 7, so that the elastic telescopic cleaning brush 514 enters the workpiece 7. After the elastic telescopic cleaning brush 514 enters the workpiece 7, the moving end of the elastic telescopic cleaning brush 514 will pop out the fixed end, so that the arc surface of the front end of the moving end contacts the inner wall of the workpiece 7. At this time, the electric lifting rod 501 is turned off, and the first motor 502 is started, which drives the rotating rod 503 to rotate. The rotation of the rotating rod 503 will drive the elastic telescopic cleaning brush 514 to rotate. The rotation of the elastic telescopic cleaning brush 514 will cause the moving end to clean the impurities on the inner wall of the workpiece 7. After the cleaning is completed, turn off motor 502 and restart electric lifting rod 501. Electric lifting rod 501 continues to move upward, causing the grease spray nozzle 504 to contact the first triangular block 516 at the bottom of slide plate 513, pushing slide plate 513 to fully open. This moves the bottom pin slot of slide plate 513 to the top of pin rod 512, where pin rod 512 is pulled back by spring number four and inserted into the pin slot, limiting slide plate 513. When grease spray nozzle 504 enters the workpiece 7, turn off electric lifting rod 501 and start motor 502. Motor 502 drives rotating rod 503 to rotate, which in turn drives grease spray nozzle 504 to rotate, spraying grease. The application of grease is performed. Simultaneously, the upward movement of the electric lifting rod 501 causes the second piston 508 to move upward. This upward movement of the second piston 508 injects air into cylinder 506 through the one-way valve 520. As the slide plate 513 moves, it moves the L-shaped rod 510 to the right. The rightward movement of the L-shaped rod 510 then moves the first piston 505 to the right, blocking the vent at the bottom of cylinder 506. After the grease application is completed by the grease spray nozzle 504, the electric lifting rod 501 is restarted. The downward movement of the electric lifting rod 501 causes the first motor 502 to move downward, which in turn causes the rotating rod 503 to move downward.The downward movement of the rotating rod 503 causes the grease spray nozzle 504 and the elastic telescopic cleaning brush 514 to move downwards. Simultaneously, the downward movement of the moving end of the electric lifting rod 501 causes the second piston 508 to move downwards. The downward movement of the second piston 508 compresses the air in the cylinder 506, forcing the air into the rotating rod 503 through the air supply pipe 507. The increased air pressure inside the rotating rod 503 pushes the gasket 517 upwards. The upward movement will cause the push rod 518 to move upward, which in turn will push the elastic telescopic cleaning brush 514 to rotate upward, preventing the elastic telescopic cleaning brush 514 from touching the lubricant applied to the inner wall of the workpiece 7 when it moves downward. When the top of the moving end of the elastic telescopic cleaning brush 514 descends to the bottom of the worktable 3, the electric servo cylinder 401 is activated, causing the moving end of the electric servo cylinder 401 to move downward, pushing the slide rod 404 downward. The downward movement of the slide rod 404 will push the pin rod 512 to... Moving downwards, the pin 512 releases the limit on the slide plate 513, allowing it to reset via the force of the third spring. The movement of the slide plate 513 then moves the L-shaped rod 510 to the left, which in turn moves the first piston 505 to the left. This movement exposes the vent at the bottom of the cylinder 506, allowing air to escape from the cylinder and the rotating rod 503. The venting of air from the rotating rod 503 causes the shim 517 to descend, which in turn... The push rod 518 descends, causing the elastic telescopic cleaning brush 514 to lose its support. It is then reset by the torsion spring between the rotating shaft 515 and the rotating rod 503. When the slide plate 513 resets, it blocks the through-hole inside the worktable 3, preventing excess grease on the inner wall of the workpiece 7 from dripping into the bottom of the worktable 3 during sealing. After the slide plate 513 blocks the through-hole, excess grease slides into the grease reservoir 511 through the second triangular block 519 at the top of the slide plate 513.

[0049] After the oil seal of workpiece 7 in the same batch is completed, pull the moving end of the telescopic rod 609 so that the moving end of the telescopic rod 609 is at the bottom of the limit groove. When the pin rod 512 is pushed downward by the slide rod 404, it drives the telescopic rod 609 to move downward. The downward movement of the telescopic rod 609 will drive the first rack 612 to move downward. The downward movement of the first rack 612 will drive the gear 614 to rotate. The rotation of the gear 614 will drive the second rack 613 to move upward. The upward movement of the second rack 613 will touch the switch of the heating plate 608, causing the heating plate 608 to start heating the grease in the grease storage cylinder 511. At the same time, the gear 61... 4. Rotating the valve 607 will open the valve, allowing the grease to enter the centrifuge 601 through the grease delivery tube 603. After entering the centrifuge 601, the grease will first go to the funnel 604, and then pass through the filter plate 605 to filter impurities in the grease. The filtered grease will then enter the centrifuge tank inside the centrifuge 601 through the inclined surface at the bottom of the funnel 604. At the same time, the second motor 602 will be started. The rotation of the output end of the second motor 602 will drive the scraper 606 to rotate. The rotation of the scraper 606 will scrape the impurities on the surface of the filter plate 605, preventing impurities from accumulating and clogging the grease outlet at the bottom of the grease delivery tube 603 for a long time.
