Description

Technical Field

[0001] This invention relates to the field of high-speed oil seal assembly technology, and more specifically to a high-speed oil seal assembly device for new energy vehicles. Background Technology

[0002] High-speed oil seals in new energy vehicles are core sealing components of electric drive systems (such as motors and reducers). Their installation positions are focused on high-speed rotating shaft components in the electric drive system. They are designed to prevent lubricating oil leakage, isolate external impurities from intrusion, and ensure the stable operation of the electric drive system under harsh conditions such as high speed, high temperature, and frequent start-stop.

[0003] Currently, the assembly of high-speed oil seals and motor reducer boxes (hereinafter collectively referred to as boxes) on the assembly line is mostly done by workers directly assembling them on the conveyor belt (using a soft rubber conveyor belt to avoid damage to the connecting surface caused by rigid contact during transportation). Due to the lack of positioning fixtures to accurately fix the boxes, the boxes are prone to shifting on the conveyor belt during the assembly process. This leads to inconsistent oil seal compression when pressing the high-speed oil seal and the box, affecting the sealing performance of the oil seal. In severe cases, it can also cause lip damage and may require rework due to improper assembly, resulting in low assembly efficiency of oil seals and boxes. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-speed oil seal assembly equipment for new energy vehicles, so as to solve the problem that the oil seal compression is inconsistent when the high-speed oil seal is pressed into the housing due to the housing easily shifting on the flexible conveyor belt.

[0005] The present invention provides the following technical solution: a high-speed oil seal assembly equipment for new energy vehicles, comprising a frame, a conveyor belt between the two sides of the frame, a box being placed on the conveyor belt, a box support module on the frame for rigidly supporting the box on both sides of the conveyor belt, the box support module also for driving the box to move, a box lifting module on the frame for lifting the box above the box support module, a combined packaging module on the frame for assembling the box and oil seal, feeding the oil seal, and applying oil to the box pressing holes below the combined packaging module, an oil storage module and an oil seal placement module respectively on both sides of the conveyor belt and on the frame.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-10 This invention provides a high-speed oil seal assembly equipment for new energy vehicles, including a frame 1, a conveyor belt 2 between the two sides of the frame 1, the conveyor belt 2 being a production line type conveying structure, which can realize the continuous conveying of oil seals and workpieces to be assembled, a box being placed on the conveyor belt 2, and box support modules 3 being set on the frame 1 on both sides of the conveyor belt 2 for rigid support of the box, the box support modules 3 also being used to drive the box to move, a box lifting module 4 being set on the frame 1 above the box support modules 3 for lifting the box, and a combined packaging module 5 being set on the frame 1 behind the box lifting module 4 for assembling the box and oil seal, feeding the oil seal, and applying oil to the box pressing holes, and an oil storage module 6 and an oil seal placement module 7 being set on both sides of the conveyor belt 2 and set on the frame 1 respectively; Based on the above, the simplified steps for assembling high-speed oil seals are as follows: First, place the oil seal on the oil seal placement module 7 and fill the oil storage module 6 with lubricating oil. The box is conveyed by the conveyor belt 2 to the box support module 3. The box is lifted upward by the box lifting module 4. Then the box support module 3 operates so that the box can fall onto the box support module 3. The linear motor drives the housing support module 3 to move to the next station (the combined packaging module 5). The combined packaging module 5 applies lubricating oil to the housing press-fit hole. Then, the combined packaging module 5 moves the oil seal from the housing support module 3 to the housing press-fit hole. Finally, the combined packaging module 5 assembles the oil seal with the housing, completing the assembly of the oil seal and the housing. By using multiple modules in combination, stable support and precise positioning of the box are achieved during the conveying process, effectively avoiding the deviation problem that is prone to occur when traditional flexible conveyor belts are assembled, ensuring the positional accuracy of the box at the pressing station, and thus ensuring the consistency of the oil seal compression amount during the pressing of the high-speed oil seal and the box.

[0033] In order to provide rigid support for the enclosure; The box support module 3 includes two movable frames 301 respectively set on both sides of the conveyor belt 2. The movable frames 301 are slidably connected to the frame 1 and are driven to move by a linear motor. The top of one movable frame 301 is fixed with two slide rails 302 by bolts. The top of the two slide rails 302 is slidably connected to a support platform 303. The top of the support platform 303 is fixed with multiple positioning pins 305 by bolts. The layout of the positioning pins 305 on the support platform 303 matches the fixing holes of the box. The top of the movable frame 301 is fixed with a first hydraulic cylinder 304 by bolts, and the movable end of the first hydraulic cylinder 304 is fixed to the support platform 303. The top of the other movable frame 301 is fixed with a support frame 306 by bolts. The two movable frames 301 are fixed together by a connecting rod 307. After the box is lifted by the box lifting module 4, the first hydraulic cylinder 304 is activated. Its movable end pushes the support platform 303 to slide along the slide rail 302 towards the box, so that one end of the support platform 303 moves to the support frame 306 above the other moving frame 301. The box is slowly lowered by the box lifting module 4. At this time, the positioning pin 305 can be accurately aligned with the preset fixing hole at the bottom of the box. As the box lifting module 4 slowly lowers, the fixing hole at the bottom of the box fits into the positioning pin 305, realizing the precise positioning and stable placement of the box on the support platform 303 and the support frame 306, ensuring that the box will not shake or shift during subsequent movement. After the box is placed on the support platform 303, the linear motor drives the moving frame 301 to move along the direction of the conveyor belt 2, thereby moving the box to the bottom of the combined packaging module 5, providing a stable operating platform for subsequent oiling of the box pressing holes and oil seal assembly. The housing support module 3 achieves overall displacement through the sliding of the movable frame 301, while the setting of the connecting rod 307 ensures the synchronicity of the movement of the movable frames 301 on both sides, further ensuring the straightness and positional accuracy of the housing on the conveying path, laying a solid foundation for the precise oiling and pressing operation of the combined packaging module 5, and fundamentally solving the core problem of inconsistent oil seal compression caused by inaccurate housing positioning. It not only provides rigid support for the box, replacing the traditional flexible conveyor belt support method, effectively avoiding the box's deviation caused by the deformation or uneven friction of the conveyor belt 2, but also, by using the precise cooperation between the positioning pin 305 and the box fixing hole, it can firmly restrict the box to the support platform 303, ensuring the stability of the box's posture during movement and subsequent assembly.

[0034] In order to lift the box; The box lifting module 4 includes a second hydraulic cylinder 401 fixed to the top of the frame 1. The movable end of the second hydraulic cylinder 401 passes through the frame 1 and is fixed to a first slide 402 by bolts. The bottom of the first slide 402 is fixed with two fixing seats 403 by bolts. The bottom of the fixing seat 403 is provided with a clamping assembly for fixing the box. The clamping assembly includes a round rod 404 fixed to the bottom of the fixing seat 403. The bottom of the round rod 404 is provided with a sliding hole, and a sliding mechanism is slidably connected in the sliding hole. The top of the rod 405 is welded with a top rod 409. The outer circumference of the round rod 404 has at least one limiting groove 406, and the top rod 409 is located in the limiting groove 406. The inner walls on both sides of the limiting groove 406 are rotatably connected with a support rod 407. The bottom end of the support rod 407 has an inclined surface 408. The top of the round rod 404 has an installation groove 410. An electromagnet 411 is fixed in the installation groove 410 by bolts. The top of the slide rod 405 is an iron block. When the housing needs to be lifted, the second hydraulic cylinder 401 is activated, and its movable end extends to drive the first slide 402 to move downward. During the descent of the slide rod 405, the arc-shaped cylinder at the bottom of the slide rod 405 will press the press hole (the slide rod 405 will first move into the slide hole to the top, and then press the press hole of the housing, and then reset after pressing), making a slight adjustment to the housing to ensure that the housing can accurately match the positioning pin 305; As the first carriage 402 continues to move downward, the bottom of the slide rod 405 first contacts the conveyor belt 2. At this time, the support rod 407 is completely below the pressing hole. At this time, the electromagnet 411 is energized, and the electromagnet 411 generates magnetic force to attract the iron block at the top of the slide rod 405, thereby causing the slide rod 405 to move upward and ensuring that the slide rod 405 will not fall down, so that the top rod 409 at the top of the slide rod 405 moves upward in the limiting groove 406. During the upward movement, the top rod 409 will come into contact with the inclined surface 408 at the bottom of the support rod 407 and apply an upward thrust to the inclined surface 408, forcing the support rod 407 to rotate outward around its rotational connection point with the inner wall of the limiting groove 406. The bottom end of the strut 407 then swings outward until its inner side comes into close contact with the side wall of the box, thereby providing support for the bottom of the box. After the support rod 407 supports the box, the movable end of the second hydraulic cylinder 401 is controlled to retract, which drives the first slide 402 and the box to move upward, completing the lifting action of the box and making it detach from the surface of the conveyor belt 2, so as to prepare for the subsequent support module 3 of the box. When the box needs to be lowered, the box contacts the support platform 303. Then the electromagnet 411 is de-energized, the slide rod 405 loses its attraction, thereby resetting the slide rod 405 and the support rod 407. With this design, the box lifting module 4 can quickly and stably clamp and lift the box without the need for complex mechanical grippers, by using the initial guidance of the slide bar 405 and the pressing hole, combined with the automatic opening of the support rod 407 and the locking function of the electromagnet 411. Compared to the traditional multi-claw clamping method, it simplifies the mechanical design, reduces the requirements for the flatness of the box surface, and can also make fine adjustments to the box posture during the lifting process. This further ensures the precise docking with the box support module 3 positioning pin 305, effectively avoiding the risk of box shaking or falling off due to unstable clamping, and providing a reliable guarantee for the smooth progress of the entire assembly process.

[0035] In addition, rubber pads are provided on the contact surface between the support rod 407 and the housing to reduce friction between the support rod 407 and the housing.

[0036] The modular packaging module 5 includes a slide block 501 that slides on the top of the frame 1 and is driven by a linear motor to move on the frame 1. The bottom of the slide block 501 is sequentially provided with a feeding component, a packaging component and an oiling component. The feeding component is used for feeding the oil seal, the packaging component is used for assembling the oil seal and the housing, and the oiling component is used for applying lubricating oil to the mounting holes on the housing. When it is necessary to feed the oil seal, the linear motor drives the slide 501 to move on the frame 1, so that the feeding component is located above the oil seal placement module 7. The feeding component grabs the oil seal placed on the oil seal placement module 7. After the grab is completed, the linear motor drives the slide 501 to move, and transfers the oil seal carried by the feeding component to the box support module 3 above the box pressing hole that has been positioned, in preparation for subsequent pressing. When it is necessary to apply lubricating oil to the press-fit hole of the box, the linear motor drives the slide 501 to move on the frame 1, so that the oiling component is positioned above the oil storage module 6, and the oiling component draws the lubricating oil in the oil storage module 6. Then the linear motor drives the slide 501 to move to the box support module 3 and move it directly above the box press-fit hole that has been positioned. The oiling component then evenly applies the drawn lubricating oil to the inner wall of the box press-fit hole. After the oiling operation is completed, the linear motor drives the slide 501 to move again, so that the encapsulation component is directly above the housing press-fit hole. At this time, the encapsulation component is started to press the oil seal precisely into the housing press-fit hole, completing the final assembly of the oil seal and the housing. Through the integrated design and collaborative operation of the three functional components of material feeding, oiling, and packaging, the modular packaging module 5 enables the completion of oil seal gripping and transfer, lubrication of the box pressing holes, and final pressing assembly at the same workstation, which greatly shortens the conversion time between processes and improves the overall assembly efficiency and automation level.

[0037] In order to feed the oil seal; The feeding assembly includes a third hydraulic cylinder 502 fixed on a slide block 501. The movable end of the third hydraulic cylinder 502 passes through the slide block 501 and is fixed to a fourth slide block 513 by bolts. Two mounting brackets 519 of different heights are welded to the bottom of the fourth slide block 513. Two first clamping blocks 517 are fixed to the bottom of the mounting brackets 519 by bolts. A guide groove 520 is opened through the bottom of the mounting brackets 519. A second clamping block 518 is slidably connected in the guide groove 520. A double-acting screw 515 is rotatably connected between the inner walls of the two sides of the mounting bracket 519. The double-acting screw 515 cooperates with the second clamping block 518. A connecting shaft 514 is welded between the two double-acting screws 515. A second reduction motor 516 is fixed to one side of one of the mounting brackets 519 by bolts. The output shaft of the second reduction motor 516 is fixed to one end of the double-acting screw 515. When it is necessary to grip the oil seal, the third hydraulic cylinder 502 is activated first. The extension of the third hydraulic cylinder 502 will drive the fourth slide 513 to move downward, so that the oil seal is located between the first clamping block 517 and the second clamping block 518. Then the second reduction motor 516 is started, and its output shaft drives the bidirectional lead screw 515 to rotate. Due to the presence of the connecting shaft 514, the two bidirectional lead screws 515 rotate synchronously. When the bidirectional lead screw 515 rotates, the second clamping block 518 that cooperates with it slides horizontally towards the first clamping block 517 in the guide groove 520, so that the distance between the first clamping block 517 and the second clamping block 518 is reduced until the two clamp the two sides of the oil seal placed on the oil seal placement module 7. After clamping is completed, the movable end of the third hydraulic cylinder 502 retracts, driving the fourth slide 513 and the clamped oil seal to rise, so that it is separated from the support surface of the oil seal placement module 7. Then, the linear motor drives the slide 501 to move on the frame 1, accurately transferring the loading component carrying the oil seal to the box support module 3 above the pre-positioned box pressing hole. At this time, the movable end of the third hydraulic cylinder 502 extends again, driving the oil seal downward to a position close to the press-fit hole of the housing, preparing for the subsequent press-fit operation of the encapsulation components; When the oil seal is released, the second reduction motor 516 rotates in the reverse direction, driving the bidirectional lead screw 515 to reverse, causing the second clamping block 518 to slide away from the first clamping block 517, releasing the clamping of the oil seal so that the encapsulation assembly can be pressed into place. The clamping block opening and closing structure driven by the bidirectional lead screw 515, combined with multiple height clamping points, achieves stable gripping and precise transfer of oil seals. Its compact structure and rapid action response can effectively adapt to the gripping needs of oil seals of different specifications, providing strong support for the efficient operation of the modular packaging module 5.

[0038] To facilitate the assembly of the oil seal and the housing; The encapsulation assembly includes a fourth hydraulic cylinder 503 fixed to the top of the slide 501. The movable end of the fourth hydraulic cylinder 503 passes through the slide 501 and is fixed to a third slide 510 by bolts. The bottom of the third slide 510 is fixed with two lower pressure rods 511 of different lengths by bolts. The bottom of the lower pressure rods 511 is welded with a lower pressure cover 512. When it is necessary to press the oil seal and the housing, the fourth hydraulic cylinder 503 is activated, and its movable end extends to drive the third slide 510 to move downward, thereby causing the lower pressure cover 512 at the bottom of the lower pressure rod 511 to move downward simultaneously. As the movable end of the fourth hydraulic cylinder 503 continues to extend, the lower pressure cover 512 applies a uniform and vertically downward pressure to the oil seal, pressing the oil seal smoothly into the press-fit hole of the housing. After the pressing is completed, the movable end of the fourth hydraulic cylinder 503 retracts, driving the third slide 510, the lower pressing rod 511, and the lower pressing cover 512 to return to their original positions, waiting for the next pressing command. This simple, press-fit design, through the stable driving force provided by the fourth hydraulic cylinder 503, enables efficient and reliable assembly of the oil seal and the housing, ensuring the uniformity of force and the accuracy of stroke during the press-fitting process, and further improving the overall assembly quality and consistency.

[0039] To apply lubricant to the mounting holes on the enclosure; The oiling assembly includes a fifth hydraulic cylinder 504 fixed to the top of the slide block 501. The movable end of the fifth hydraulic cylinder 504 passes through the slide block 501 and is fixed to a second slide block 505 by bolts. Two first reduction motors 506 are fixed to the bottom inner wall of the second slide block 505 by bolts. The output shaft of the first reduction motor 506 is fixed to a connecting plate 507 by bolts. Multiple inclined fixing posts 508 are fixed to the bottom of the connecting plate 507 by bolts. A sponge sleeve 509 is interference-fitted to the bottom end of the fixing post 508. When it is necessary to apply lubricating oil to the press-fit hole of the housing, the fifth hydraulic cylinder 504 is activated, and its movable end extends to drive the second slide 505 to move downward, so that the sponge sleeve 509 at the bottom of the connecting plate 507 is immersed in the lubricating oil in the oil storage module 6, thereby making the sponge sleeve 509 wet with lubricating oil. After adsorption is completed, the movable end of the fifth hydraulic cylinder 504 retracts, driving the second slide 505 and the sponge sleeve 509 with adsorbed lubricating oil to rise. Then, the linear motor drives the slide 501 to move directly above the box body press-fit hole that has been positioned on the box body support module 3. At this time, the movable end of the fifth hydraulic cylinder 504 extends again, driving the sponge sleeve 509 to move downward and insert into the pressing hole of the housing. At the same time, the first reduction motor 506 continues to drive the sponge sleeve 509 to rotate. The rotating sponge sleeve 509 evenly applies the lubricating oil it absorbs to the inner wall of the pressing hole. The inclined fixed column 508 allows the sponge sleeve 509 to fully contact the inner wall of the pressing hole at different heights and angles, ensuring that there are no dead corners in the oiling process. After the oiling is completed, the fifth hydraulic cylinder 504 retracts, causing the sponge sleeve 509 to exit the press-fit hole, thus completing the entire oiling operation. By employing a rotary immersion oiling design combined with a multi-directional contact sponge sleeve structure, uniform and efficient application of lubricating oil to the inner wall of the press-fit hole is achieved. This not only ensures the lubrication effect during oil seal press-fitting but also reduces frictional resistance and component damage during assembly, providing an effective guarantee for smooth subsequent oil seal press-fitting and improved sealing performance.

[0040] In order to store the oil and remove excess oil from the sponge sleeve 509; The oil storage module 6 includes a first mounting plate 601 fixed on the frame 1. The top of the first mounting plate 601 has two oil draining grooves 602. The top of the first mounting plate 601 is slidably connected to a movable frame 603. A strainer frame 604 is fixed to one side of the movable frame 603 by bolts. A squeezing column 605 is welded to the middle part of the strainer frame 604. An electric push rod 606 is fixed to one side of the first mounting plate 601 by bolts, and the movable end of the electric push rod 606 is fixed to the movable frame 603. When the fifth hydraulic cylinder 504 extends, the sponge sleeve 509 will enter the oil drain 602 containing lubricating oil, at which time the sponge sleeve 509 fully absorbs the lubricating oil; when the sponge sleeve 509 has finished absorbing the lubricating oil, the fifth hydraulic cylinder 504 retracts and drives the sponge sleeve 509 away from the oil drain 602. Then the electric push rod 606 is activated, and its movable end extends to push the movable frame 603 to slide on the first mounting plate 601, so that the mesh frame 604 moves to directly below the sponge sleeve 509; Next, the fifth hydraulic cylinder 504 extends again, driving the sponge sleeve 509 to move downward and be squeezed by the mesh frame 604, so that the oil on the contact surface between the sponge sleeve 509 and the mesh frame 604 is squeezed out. At the same time, the extrusion column 605 will be inserted into the central hole of the cavity formed by multiple sponge sleeves 509, and the sponge sleeves 509 will be squeezed from the inside. This can effectively squeeze out the excess lubricating oil adsorbed on the sponge sleeves 509, and avoid the oil dripping onto the box or other parts of the equipment during the oiling process, causing pollution and waste. The excess lubricating oil squeezed out will drip back into the oil drain 602 below through the mesh of the strainer frame 604, thus realizing the recycling and reuse of the lubricating oil. After excess oil is removed, the electric push rod 606 retracts, causing the movable frame 603 and the strainer frame 604 to reset, so that the sponge sleeve 509 can perform subsequent oiling operations. This design not only realizes the function of storing lubricating oil, but also controls the amount of oil carried by the sponge sleeve 509 through the synergistic effect of the movable strainer frame 604 and the extrusion column 605, ensuring the cleanliness and efficiency of the oiling process, while also improving the utilization rate of lubricating oil and reducing production costs.

[0041] In order to position the oil seal; The oil seal placement module 7 includes a second mounting plate 701 fixed on the frame 1. The top of the second mounting plate 701 has two placement slots 702 with different heights. During placement, the oil seal is manually placed into the two placement slots 702. At this time, the oil seal will extend beyond the placement slots 702. At the same time, the placement slots 702 provide circumferential positioning for the oil seal, preventing the oil seal from rotating or shifting within the placement slots 702. This achieves stable placement and precise positioning of the oil seal, providing a reliable foundation for the efficient gripping of the feeding components. It effectively avoids gripping failure or gripping position deviation caused by improper placement of the oil seal, further ensuring the continuous and stable operation of the modular packaging module 5.

[0042] It should be noted that: the linear motor is used in conjunction with the slotted photoelectric switch to achieve precise distance control; the electric push rod 606 is used in conjunction with a magnetic switch or proximity switch to achieve precise control of the push rod's extension and retraction displacement; the first hydraulic cylinder 304, the second hydraulic cylinder 401, the third hydraulic cylinder 502, the fourth hydraulic cylinder 503, and the fifth hydraulic cylinder 504 are all actuators in the hydraulic system, achieving extension and retraction functions in conjunction with the hydraulic system, and achieving precise control of the hydraulic cylinder piston rod's extension and retraction displacement in conjunction with magnetic switches, proximity switches, or photoelectric switches; the first geared motor 506 and the second geared motor 516 are both drive elements with reducers, which, in conjunction with the controller and encoder... The device works in conjunction with the output shaft to achieve precise adjustment of the speed and angle of rotation, ensuring precise control of action parameters such as the opening and closing range of the clamping block and the rotation speed of the sponge sleeve 509. The electromagnet 411, through linkage with the relay and limit switch, achieves precise matching of the magnetic force on and off and the clamping timing. The two ends of the bidirectional lead screw 515 are respectively provided with threaded sections with opposite directions of rotation, and the two threaded sections are respectively connected to the second clamping block 518 on the corresponding side through ball sleeves, so that when the bidirectional lead screw 515 rotates, the two second clamping blocks 518 can move inward or outward at the same time, thereby achieving synchronous clamping or release of the oil seal. Those skilled in the art can set it according to actual needs, which will not be elaborated in detail here.

[0043] The present invention is used in the following steps: S1: The oil seal is manually placed in the two placement slots 702. The oil seal will extend beyond the placement slots 702. At the same time, the placement slots 702 play a circumferential positioning role for the oil seal, preventing the oil seal from rotating or shifting within the placement slots 702, and guiding the lubricating oil into the drain slot 602. S2: When the box conveyed by the conveyor belt 2 reaches below the second hydraulic cylinder 401, the conveyor belt 2 stops running and the second hydraulic cylinder 401 is started. Its movable end extends and drives the first slide 402 to move downward. During the falling process of the slide rod 405, the arc-shaped cylinder at the bottom of the slide rod 405 will squeeze the pressing hole (the slide rod 405 will first move into the sliding hole to the top, and then squeeze the pressing hole of the box, and then reset after squeezing), making a slight adjustment to the box; S3: As the first slide 402 continues to move downward, the bottom of the slide rod 405 first contacts the conveyor belt 2. Under the reaction force of the conveyor belt 2, the slide rod 405 slides upward relative to the round rod 404. The top rod 409 at the top of the slide rod 405 moves upward in the limiting groove 406 and contacts the inclined surface 408 at the bottom of the support rod 407, and applies an upward thrust to the inclined surface 408, forcing the support rod 407 to rotate outward around its rotational connection point with the inner wall of the limiting groove 406. S4: As the first slide 402 continues to move downward, the bottom of the slide rod 405 first contacts the conveyor belt 2. At this time, the support rod 407 is completely below the pressing hole. At this time, the electromagnet 411 is energized, and the electromagnet 411 generates magnetic force to attract the iron block at the top of the slide rod 405, thereby causing the slide rod 405 to move upward and ensuring that the slide rod 405 will not fall down, thereby causing the top rod 409 at the top of the slide rod 405 to move upward in the limiting groove 406. S5: During the upward movement, the top rod 409 will contact the inclined surface 408 at the bottom of the support rod 407 and apply an upward thrust to the inclined surface 408, forcing the support rod 407 to rotate outward around the rotation connection point with the inner wall of the limiting groove 406. The bottom end of the support rod 407 will swing outward until its inner side is in close contact with the side wall of the box, thereby achieving support for the bottom of the box. S6: After the support rod 407 supports the box body, control the movable end of the second hydraulic cylinder 401 to retract, drive the first slide 402 and the box body to move upward, and complete the lifting action of the box body; S7: Start the first hydraulic cylinder 304, and its movable end pushes the support platform 303 to slide along the slide rail 302 towards the box body, so that one end of the support platform 303 moves to the support frame 306 above the other movable frame 301. S8: Control the movable end of the second hydraulic cylinder 401 to slowly extend, so that the box body contacts the support platform 303. At this time, the fixing hole at the bottom of the box body fits into the positioning pin 305, so that the box body is accurately positioned and stably placed on the support platform 303 and the support frame 306. Then the electromagnet 411 is de-energized, the slide rod 405 loses its attraction, so that the slide rod 405 is reset, and the support rod 407 is reset, and the second hydraulic cylinder 401 is reset. S9: The linear motor drives the moving frame 301 to move along the direction of the conveyor belt 2, thereby moving the box to the underside of the slide block 501, providing a stable operating platform for subsequent oiling of the box pressing holes and oil seal assembly. S10: The linear motor drives the slide 501 to move on the frame 1, so that the feeding component is above the oil seal placement module 7. At this time, the oiling component is above the support platform 303 and matches the position of the pressing hole of the box. S11: Start the third hydraulic cylinder 502. The extension of the third hydraulic cylinder 502 will drive the fourth slide 513 to move downward, so that the oil seal is located between the first clamping block 517 and the second clamping block 518. S12: Start the second reduction motor 516. Its output shaft drives the bidirectional lead screw 515 to rotate. Due to the presence of the connecting shaft 514, the two bidirectional lead screws 515 rotate synchronously. When the bidirectional lead screw 515 rotates, the second clamping block 518 that cooperates with it slides horizontally towards the first clamping block 517 in the guide groove 520, so that the distance between the first clamping block 517 and the second clamping block 518 is reduced until the two clamp the two sides of the oil seal placed on the oil seal placement module 7. S13: After clamping is completed, the movable end of the third hydraulic cylinder 502 retracts, driving the fourth slide 513 and the clamped oil seal to rise upward, so that they are separated from the support surface of the oil seal placement module 7. S14: During this process, the fifth hydraulic cylinder 504 is activated, driving the sponge sleeve 509 to move downward and insert into the pressing hole of the housing. At the same time, the first reduction motor 506 continues to drive the sponge sleeve 509 to rotate. The rotating sponge sleeve 509 evenly spreads the lubricating oil it absorbs onto the inner wall of the pressing hole. The inclined fixed column 508 allows the sponge sleeve 509 to fully contact the inner wall of the pressing hole at different heights and angles. S15: After the oiling is completed, the fifth hydraulic cylinder 504 retracts, causing the sponge sleeve 509 to exit the press-fit hole, thus completing the entire oiling operation. S16: Drive the slide block 501 to move on the frame 1 by a linear motor, and accurately transfer the feeding component carrying the oil seal to the box support module 3 above the box pressing hole that has been positioned. S17: The movable end of the third hydraulic cylinder 502 extends again, causing the oil seal to move downward to a position close to the press-fit hole of the housing. The second reduction motor 516 rotates in the opposite direction, driving the bidirectional lead screw 515 to reverse, causing the second clamping block 518 to slide away from the first clamping block 517, releasing the clamping of the oil seal. After the clamping is released, the third hydraulic cylinder 502 resets. S18: During this process, the fifth hydraulic cylinder 504 is started, and its movable end extends to drive the second slide 505 to move downward, so that the sponge sleeve 509 at the bottom of the connecting plate 507 is immersed in the lubricating oil in the oil storage module 6, thereby making the sponge sleeve 509 wet with lubricating oil. After the adsorption is completed, the movable end of the fifth hydraulic cylinder 504 retracts. S19: Start the electric push rod 606, its movable end extends to push the movable frame 603 to slide on the first mounting plate 601, so that the mesh frame 604 moves to the underside of the sponge sleeve 509, the fifth hydraulic cylinder 504 extends again, drives the sponge sleeve 509 to move downward and be squeezed by the mesh frame 604, so that the oil on the contact surface between the sponge sleeve 509 and the mesh frame 604 is squeezed out. S20: At the same time, the extrusion column 605 will be inserted into the central hole of the cavity formed by multiple sponge sleeves 509, and the sponge sleeves 509 will be squeezed from the inside, which can effectively squeeze out the excess lubricating oil adsorbed on the sponge sleeves 509. Then the electric push rod 606 retracts and drives the movable frame 603 and the strainer frame 604 to reset, so that the sponge sleeves 509 can perform subsequent oiling operations. S21: The linear motor drives the slide 501 to move again, so that the lower cover 512 is located directly above the press hole of the housing. The fourth hydraulic cylinder 503 is activated, and its movable end extends to drive the third slide 510 to move downward, thereby causing the lower cover 512 at the bottom of the lower press rod 511 to move downward synchronously. S22: As the movable end of the fourth hydraulic cylinder 503 continues to extend, the lower pressure cover 512 applies a uniform and vertically downward pressure to the oil seal, pressing the oil seal smoothly into the pressing hole of the housing. After pressing is completed, the movable end of the fourth hydraulic cylinder 503 retracts, driving the third slide 510, the lower pressure rod 511, and the lower pressure cover 512 to return to their original positions, waiting for the next pressing command. S23: Through the coordinated use of multiple modules, stable support and precise positioning of the box are achieved during the conveying process, effectively avoiding the deviation problem that is prone to occur when traditional flexible conveyor belts are assembled, ensuring the positional accuracy of the box at the pressing station, thereby ensuring the consistency of the oil seal compression amount during the pressing of the high-speed oil seal and the box. It should be noted that if steps S18-S20 are not executed when assembling the oil seal and housing for the last time, and steps S18-S20 are executed first when assembling the oil seal and housing for the first time.
