Description

Technical Field

[0001] This invention relates to the field of track roller technology, and in particular to a track roller assembly system. Background Technology

[0002] Track rollers are a key component of the "four wheels and one track" system in the chassis of tracked construction machinery (such as excavators, bulldozers, and tracked drilling rigs). Their main function is to support the weight of the entire machine, transfer the load to the track pads, and guide the track to wind correctly, preventing lateral slippage. The main body of the track roller is usually cylindrical, and to effectively grip the track and prevent derailment, the track roller body typically has flanges on both sides.

[0003] Currently, the industry mostly uses manual or semi-automatic processes to assemble track rollers. The assembly process can be divided into the following steps: cleaning the wheel body, axle, and bearing → manually or semi-automatically pressing the bushing → manually pressing the floating oil seal → manually assembling the axle → semi-automatic break-in → manual air tightness test → manual oiling → semi-automatic running-in. Among these steps, cleaning the wheel body, axle, and bearing is a relatively important step in the assembly system.

[0004] Existing track rollers are typically mounted on fixed workstations and cleaned using cleaning machines. For example, patent document CN116175156A discloses a track roller assembly system that integrates a cleaning agent into the front end of the assembly system. While this improves the overall assembly efficiency, it has limitations in cleaning. Furthermore, during the pressing of bushings and floating oil seals, oil and dust on the track rollers can affect the bushings and subsequent lubrication. Therefore, when cleaning at a fixed workstation, the track rollers need to be soaked or sprayed, and the cleaning time needs to be extended. While this method removes impurities, it is time-consuming, and in some hard-to-reach areas (e.g., the cavities inside the track rollers), the vertically fixed position of the product makes it difficult for water to quickly carry away impurities. Summary of the Invention

[0005] The present invention provides a track roller assembly system to solve the above problems.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a support roller assembly system, including a transport module, a pre-treatment module, and a fixing module for fixing the support roller, wherein the transport module includes a horizontal conveying structure for driving a movable part to move linearly, characterized in that: the movable part is disposed on the top of the fixing module; the pre-treatment module is fixedly disposed on the transport module, and the pre-treatment module includes cleaning structures horizontally alternately disposed on both sides of the movable part, forming a cleaning space between the two cleaning structures for the fixing module to pass through, and each cleaning structure has a cleaning part facing the cleaning space on its inner side; The fixed module includes a fixing mechanism and an end lifting structure disposed on the movable part; the fixing mechanism includes multiple radially movable fixed wheels, which are evenly distributed circumferentially on the same vertical plane; the outer wall of the fixed wheel is arc-shaped and can abut against the outer wall of the support wheel, and the end of the support wheel faces the cleaning part; the end lifting structure includes multiple liftable pressing heads, which can abut against the outer walls of both ends of the support wheel coaxially and drive the support wheel to deflect relative to its own axis.

[0007] In a further technical solution, the fixing mechanism also includes a fixing seat disposed on the movable part, and a horizontal clamp and a vertical clamp are mounted on the fixing seat; The horizontal clamp includes a horizontal drive rod that passes through a fixed base. Both ends of the horizontal drive rod are provided with first sliding frames. The two first sliding frames can be driven by the horizontal drive rod and move closer or further apart from each other in the horizontal direction. The fixed wheel is provided on the opposite side of the two first sliding frames. The vertical clamp includes a vertical drive rod that passes through a fixed base. Both ends of the vertical drive rod are provided with second sliding frames. The two second sliding frames can be driven by the vertical drive rod and move closer or further apart from each other in the vertical direction. The fixed wheel is provided on the opposite side of the two second sliding frames. The horizontal drive rod and the vertical drive rod are combined to form a cross shape.

[0008] In a further technical solution, a clamping column is provided on the second sliding frame, and a mounting base is provided at the end of the clamping column away from the second sliding frame. Two pressing heads are provided on the side surface of the mounting base away from the clamping column, and a corresponding fixed wheel rotatably connected to the mounting base is provided between the two pressing heads.

[0009] A further technical solution involves two piston cylinders mounted on the mounting base above the support roller. A piston rod is movably connected inside each piston cylinder. A corresponding pressing head is slidably fitted onto the bottom outer wall of each piston cylinder. The bottom end of the piston rod slides through the bottom of the piston cylinder and is fixedly connected to the corresponding pressing head. An air injection pipe is provided at the top of each piston cylinder. An elastic element is fitted onto the piston rod, located inside the piston cylinder and between the bottom of the piston cylinder and the piston rod. The two piston rods can drive the corresponding pressing head to act on the support roller, causing the support roller to deflect relative to its own axis.

[0010] A further technical solution is that the two pressing heads located below the support roller are fixed on the mounting base and each end is provided with a thickened block with an arc-shaped surface, and the thickened block can abut against the outer wall of the support roller.

[0011] In a further technical solution, the two gas injection pipes operate alternately, with one gas injection pipe injecting gas into the corresponding piston cylinder while the other gas injection pipe draws gas from the corresponding piston cylinder.

[0012] In a further technical solution, the horizontal conveying structure includes a frame, on which a sliding guide rail is provided, and a vertical positioning frame located in the cleaning space is connected to the sliding guide rail, the vertical positioning frame being fixed on the movable part; The fixed base is fixedly connected to the vertical positioning frame, and a screw is rotatably connected to the vertical positioning frame. A gear is fixedly connected to the bottom end of the screw. The frame is provided with a toothed rod located at the bottom of the cleaning space. Multiple toothed blocks that mesh with the gear are spaced apart on the toothed rod. The vertical positioning frame is also provided with a blade fan that can be driven to rotate by the screw. When the support roller is fixed, the blade fan faces the support roller.

[0013] In a further technical solution, the diameter of the blade fan is less than or equal to the diameter of the support roller.

[0014] A further technical solution is that a positioning area is provided at the center of the outer periphery of the support roller. The positioning area is annular. When the support roller is fixed, the wheel surfaces of the plurality of fixed wheels abut against the positioning area, and the line connecting the centers of the plurality of fixed wheels forms a circle, and the center point of the circle coincides with the central axis of the support roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The moving part is driven linearly by the horizontal conveying structure of the transport module, causing the fixed module to move synchronously with the moving part. The fixed module carries the support rollers linearly into the cleaning space. Multiple cleaning structures of the pretreatment module clean the support rollers from all angles, and the end lifting structure can adjust the angle of the support rollers to ensure that all surfaces of the support rollers are effectively cleaned, improving cleaning efficiency and avoiding cleaning dead zones. At the same time, adjusting the angle of the support rollers by the end lifting structure also allows impurities to be discharged quickly.

[0016] By fixing multiple fixed wheels simultaneously to the outer peripheral wall of the support roller, the support roller can be fixed. Then, the fixed module is driven to move along the cleaning space through the horizontal conveying structure. The cleaning unit performs the cleaning operation. Then, the piston rod in the pressing head is guided to abut against the outer peripheral wall of the end of the support roller and drive the support roller to deflect around the center of the circle where the centers of the multiple fixed wheels are located, so that all positions of the support roller can be cleaned.

[0020] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Example like Figures 1 to 15 As shown, the present invention provides a support roller assembly system, including a transport module 1, a pretreatment module 2, and a fixing module 3 for fixing the support roller. The transport module 1 includes a horizontal conveying structure 4 that drives a movable part 9 to move linearly. The movable part 9 is disposed on the top of the fixing module 3. The pretreatment module 2 is fixedly disposed on the transport module 1 and includes cleaning structures 5 horizontally alternately arranged on both sides of the movable part 9. A cleaning space is formed between the two cleaning structures 5 for the fixing module 3 to pass through. The inner side of each cleaning structure 5 is provided with a cleaning space facing the cleaning space. The cleaning section 6 is located between the movable section 9 and the fixed module 3 includes a fixing mechanism 7 and an end lifting structure 8. The fixing mechanism 7 includes multiple radially movable fixed wheels 10, which are evenly distributed circumferentially on the same vertical plane. The outer wall of the fixed wheel 10 is arc-shaped and can abut against the outer wall of the support wheel, so that the end of the support wheel faces the cleaning section 6. The end lifting structure 8 includes multiple liftable pressing heads 11, which can abut against the outer walls of both ends of the support wheel coaxially and drive the support wheel to deflect relative to its own axis.

[0022] The aforementioned horizontal conveying structure 4 is an existing linear motion module, mainly including a frame, on which a sliding guide rail 22 is provided. The movable part 9 is slidably sleeved on the sliding guide rail 22. The sliding guide rail 22 is also provided with a motor-driven lead screw or synchronous belt mechanism. The synchronous belt mechanism is a synchronous belt driven by two synchronous pulleys. The synchronous belt is provided with a synchronous belt clamp. The movable part 9 is matched and connected to the lead screw or fixed on the synchronous belt clamp, so that the movable part 9 moves linearly on the sliding guide rail 22. The specific details will not be elaborated further.

[0023] With the above design, the moving part 9 can be driven by the horizontal conveying structure 4 of the transport module 1, and the fixed module 3 can move synchronously with the moving part 9 and carry the support rollers into the cleaning space in a straight line. The multiple cleaning structures 5 of the pretreatment module 2 can clean the support rollers in all directions, and the end lifting structure 8 can adjust the angle of the support rollers to ensure that all surfaces of the support rollers can be effectively cleaned, thereby improving cleaning efficiency and cleaning effect, thus solving the problem of cleaning dead corners in the prior art.

[0024] Meanwhile, by adjusting the angle of the support roller through the end lifting structure 8, impurities can be discharged quickly, preventing impurities from accumulating due to the fixed state of the support roller.

[0025] Specifically, multiple fixed wheels 10 are simultaneously fixed to the outer peripheral wall of the support wheel to fix the support wheel, and then the fixed module 3 is driven to move along the cleaning space by the horizontal conveying structure 4, and then the cleaning unit 6 performs a cleaning operation on the support wheel.

[0026] In the above scheme, the cleaning structure 5 can be a long strip plate structure with spraying function, such as a long strip plate structure composed of multiple spray pipes, and the cleaning part 6 can be a spray head.

[0027] In a further technical solution, the fixing mechanism 7 also includes a fixing seat 12 disposed on the movable part 9. A horizontal clamp and a vertical clamp are mounted on the fixing seat 12. The horizontal clamp includes a horizontal drive rod 13 passing through the fixing seat 12. Both ends of the horizontal drive rod 13 are provided with a first sliding frame 14. The two first sliding frames 14 can be driven by the horizontal drive rod 13 and move closer or further away from each other in the horizontal direction. Each of the two first sliding frames 14 is provided with a corresponding fixed wheel 10 on its opposite side. The vertical clamp includes a vertical drive rod 28 passing through the fixing seat 12. Both ends of the vertical drive rod 28 are provided with a second sliding frame 15. The two second sliding frames 15 can be driven by the vertical drive rod 28 and move closer or further away from each other in the vertical direction. Each of the two second sliding frames 15 is also provided with a corresponding fixed wheel 10 on its opposite side. The horizontal drive rod 13 and the vertical drive rod 28 are combined to form a cross shape.

[0028] like Figure 11 Both the horizontal drive rod 13 and the vertical drive rod 28 are driven to rotate by their respective drive motors. With the above design, the four fixed wheels 10 can be synchronously controlled to move towards or away from the center of the support wheel from both the horizontal and vertical directions through the cross-shaped drive structure formed by the horizontal drive rod 13 and the vertical drive rod 28. This enables the support wheel to be quickly and accurately centered and stably clamped in the horizontal and vertical planes, ensuring that the support wheel will not deviate during the conveying and cleaning process.

[0029] A further technical solution is provided with a clamping column 16 on the second sliding frame 15. A mounting base 17 is provided at the end of the clamping column 16 away from the second sliding frame 15. Two pressing heads 11 are fixed on the side surface of the mounting base 17 away from the clamping column 16, and a fixed wheel 10 rotatably connected to the mounting base 17 is provided between the two pressing heads 11.

[0030] With the above design, the end lifting structure 8 can be directly set on the mounting base 17, so that the pressing head 11 is very close to both ends of the fixed wheel 10. Without changing the clamping state, the pressing head 11 can directly apply force to the outer wall of the end of the support wheel, so as to achieve precise deflection of the support wheel with the fixed wheel 10 as the rotation center, and make angle adjustment for subsequent cleaning so that impurities can be discharged more quickly.

[0031] by Figure 8 For example, the pressing head 11 located above the support roller achieves offset by applying pressure to both ends of the support roller.

[0032] In a further technical solution, two piston cylinders 18 are mounted on the mounting base 17 above the support roller; a piston rod 19 is movably connected inside the piston cylinder 18, and a corresponding pressing head 11 is slidably fitted on the bottom outer wall of the piston cylinder 18. The bottom end of the piston rod 19 slides through the bottom of the piston cylinder 18 and is fixedly connected to the corresponding pressing head 11. An air injection pipe 21 is provided at the top of each of the two piston cylinders 18, and an elastic element 20 is fitted on the piston rod 19. The elastic element 20 is located inside the piston cylinder 18 and between the bottom of the piston cylinder 18 and the piston rod 19. The two piston rods 19 can drive the corresponding pressing head 11 to act on the support roller and cause the support roller to deflect relative to its own axis.

[0033] Two pressing heads 11 located below the support roller are fixed on the mounting base 17, and each end is provided with a thickened block 29 with an arc-shaped surface. The thickened block 29 can abut against the outer wall of the support roller. With the above design, the piston rod 19 can be synchronously driven by two symmetrically arranged piston cylinders 18, so as to achieve uniform and stable pressing on both ends of the support roller, avoid the tilting of the support roller or loosening of the clamp due to single-point force, and ensure the stability and reliability of the deflection action.

[0034] It should be noted that the pressing head 11 located above the support roller is not in contact with the side wall of the support roller, while the pressing head 11 below it is supported by the thickened block 29 (which can be made of rubber or sponge) to ensure stability. At the same time, the thickened block 29 can assist the deflection of the support roller through its own elastic deformation.

[0035] With the above design, the piston rod 19 can be provided with a continuous restoring force by the elastic element 20 (preferably a spring), so that the piston rod 19 can automatically retract when not in operation, avoiding interference with the support roller or other mechanisms. At the same time, it can also provide a buffer during the lifting process to protect the surface of the support roller from impact damage.

[0036] In a further technical solution, the two air injection pipes 21 operate alternately. When one air injection pipe 21 injects air into the corresponding piston cylinder 18, the other air injection pipe 21 draws air from the corresponding piston cylinder 18.

[0037] With the above design, the extension or retraction of the corresponding piston rod 19 can be driven by injecting air into one air injection pipe 21 (while simultaneously drawing air from another), thereby precisely controlling the lifting height and deflection angle of both ends of the support roller. This pneumatic method has a fast response speed, facilitates automated control, and makes the attitude adjustment of the support roller more flexible and precise.

[0038] A further technical solution includes a vertical positioning frame within the cleaning space, fixed to the movable part 9; a fixed base 12 is fixedly connected to the vertical positioning frame, and a screw 23 is rotatably connected to the vertical positioning frame. The bottom end of the screw 23 extends beyond the bottom surface of the vertical positioning frame and is fixedly connected to a gear 24; a toothed rod 25 located at the bottom of the cleaning space is provided on the frame, and multiple toothed blocks 27 that mesh with the gear 24 are spaced apart on the toothed rod 25; a blade fan 26 that can be driven to rotate by the screw 23 is also provided on the vertical positioning frame; when the support roller is fixed, the blade fan 26 faces the support roller.

[0039] With the above design, the linear motion of the vertical positioning frame can be converted into the rotational motion of the screw 23 by the meshing of the gear 24 with the toothed block 27 on the toothed rod 25, thereby driving the blade fan 26 to rotate. When the support roller moves with the movable part 9, the gear 24 rotates a certain angle for every toothed block 27 distance it moves, so that the blade fan 26 can blow away and clean the impurities and dust on the support roller, accelerating the discharge of impurities.

[0040] Specifically, a retaining ring 261 is coaxially rotatably connected to the outer wall of the blade fan 26, and the retaining ring 261 is fixedly connected to the movable part 9. The blade fan 26 and the screw 23 may each be provided with meshing bevel gears, or as... Figure 12 As shown, the blade fan 26 and the screw 23 can be a worm gear structure. A worm gear is coaxially fixed on the rotating shaft in the middle of the blade fan 26. The screw 23 is a worm and the worm gear is matched, so that the screw 23 drives the bevel gear or worm gear to rotate, thereby driving the blade fan 26 to rotate on the fixed ring 261.

[0041] A further technical solution is that the diameter of the blade fan 26 is less than or equal to the diameter of the support roller.

[0042] With the above design, by making the diameter of the blade fan 26 smaller than or equal to the diameter of the support roller, it can be ensured that the airflow or force generated by the blade fan 26 can be concentrated on the surface of the support roller, avoiding energy loss. At the same time, it can also prevent the blade fan 26 from interfering with other mechanisms in the cleaning space, ensuring operational safety.

[0043] A further technical solution involves providing a positioning area at the center of the outer periphery of the support roller. Figure 8 As shown at point Q, the positioning area is annular. When the support wheel is fixed, the wheel surfaces of multiple fixed wheels 10 abut against the positioning area, and the lines connecting the centers of the multiple fixed wheels 10 form a circle, with the center point of the circle coinciding with the central axis of the support wheel.

[0044] With the above design, the wheel surfaces of all fixed wheels 10 can be made to abut against the annular positioning area of ​​the support wheel, and the center of the circle formed by connecting the centers of the circles can be made to coincide with the center of the support wheel. This ensures that the support wheel is firmly clamped and subjected to uniform force, avoids excessive local stress that could cause deformation or surface damage to the support wheel, and at the same time ensures the center positioning accuracy of the support wheel, providing a reference for subsequent processing.

[0045] It is important to note that the cleaning section 6 is positioned directly opposite the end of the support roller. This ensures that the sprayed cleaning fluid not only sprays the outer surface of the support roller housing but also penetrates into the housing for rinsing. This is because the main body of the support roller is typically cylindrical, allowing the cleaning fluid to easily enter the housing. Simultaneously, the support roller deflects around the fixed rollers 10 evenly distributed on its outer side, changing the cleaning angle and enabling comprehensive cleaning or treatment of the support roller. Therefore, the sprayed liquid can fully penetrate the housing and accelerate the flushing and removal of impurities.

[0046] Meanwhile, the bottom and sides of the cleaning space can be set as a sealed structure, the movable part 9 can be set as a lifting mechanism, and the fixed mechanism 7 is positioned on the lifting head of the lifting mechanism so as to soak and clean the support roller.

[0047] Working principle: First, the support roller is placed between the four fixed rollers 10. Then, the horizontal drive rod 13 and the vertical drive rod 28 are driven by a motor to synchronously control the four fixed rollers 10 to move towards the center of the support roller from both horizontal and vertical directions, so that the support roller is clamped and fixed. Then, the sliding guide rail 22 is driven to pull the movable part 9 to move in the cleaning space. When the movable part 9 moves, the support roller will also move. At the same time, the linear motion of the vertical positioning frame is converted into the rotational motion of the screw 23 through the meshing of the gear 24 and the tooth block 27 on the tooth block rod 25, thereby driving the blade fan 26 to rotate and blow on the support roller to accelerate the discharge of impurities. However, in order to avoid cleaning dead corners, such as Figure 14 and Figure 15First, air needs to be injected into one of the air injection pipes 21, while air is simultaneously drawn in from the other air injection pipe 21. This drives the extension and retraction of the corresponding piston rod 19, and the corresponding pressing head 11 presses against the support roller. Then, the support roller deflects with the fixed roller 10 as the fulcrum and with the assistance of the thickened block 29 (the angle of the press is small to prevent the support roller from detaching). Then, one end of the support roller is raised, thereby changing the cleaning angle of the support roller so that the cleaning liquid can quickly remove impurities and achieve all-round cleaning or treatment of the support roller.

[0048] It should be noted that: Figure 15 Generally, the fixed wheel 10 and the support wheel are in point contact, which can reduce torsional resistance. Secondly, the positioning area Q is generally set at the center of the support wheel. When clamping at four points, balanced clamping can be quickly achieved. Without pressure, the support wheel is balanced by gravity at both ends with the fixed wheel 10 as the center. Sometimes, it is possible to make the right side of the support wheel have a larger weight, so that the left side of the support wheel tilts up and the right side drops. Injecting air into the air injection pipe 21 on the left side causes the piston rod 19 on the left side to extend and press down the left side of the support wheel. This makes it easier for the piston rod 19 on the right side to extend and drop down later.

[0049] By following the above steps, a seemingly large-torque "overall deflection" action can be broken down into two consecutive, effortless "press-lift" steps. This involves using a pre-set imbalance of the center of gravity to transform gravity from an obstacle to a facilitator, significantly reducing the driving force required. Simultaneously, point contact greatly reduces frictional resistance, making this minute, incremental adjustment possible. With surface contact, the static friction would be much greater, making this process difficult to achieve.

[0050] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
