Description

Technical Field

[0001] This utility model relates to the field of track roller technology, and in particular to an automatic assembly machine for track roller rims. Background Technology

[0002] Track rollers are key load-bearing components of the walking system in tracked construction machinery. Internally, they use snap rings to axially position bearings, seals, and other components to prevent movement under complex operating conditions. Traditional track roller snap rings mostly use an open-type elastic retaining ring structure, which presents significant difficulties during installation. First, because the snap ring groove is usually located in a narrow space within the inner wall of the track roller body or bushing, the operating space is extremely limited, making it difficult for standard snap ring pliers to effectively reach in and open the snap ring. The existing method of installing track roller snap rings has become a technical bottleneck restricting the convenience of maintenance and the improvement of work efficiency. Therefore, there is a lack of a device that can automatically install the snap ring. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model discloses an automatic assembly machine for support roller retaining rings, comprising a mounting platform, on which a support frame is fixedly mounted. The support frame is V-shaped, and a lower clamping plate is slidably mounted in the middle of the support frame. The lower clamping plate is driven by a short electric cylinder. A lifting plate is slidably mounted on the support frame, and an upper clamping plate is fixedly mounted below the lifting plate. The lower end of the upper clamping plate and the upper end of the lower clamping plate are both V-shaped, and the upper and lower clamping plates together clamp the support roller. A vertical plate is fixedly mounted at one end of the mounting platform, and a retaining ring box is fixedly mounted at the upper end of the vertical plate. A central shaft is fixedly mounted inside the retaining ring box, and multiple retaining rings are sleeved on the central shaft. An installation assembly is mounted on the mounting platform to install the retaining rings into the support roller. Through the above technical solution, the support roller is already stable when placed on the support frame, and the V-shaped clamping of the upper and lower clamping plates provides even greater stability. Furthermore, both the upper and lower clamping plates are movable to facilitate height adjustment, allowing for accurate alignment of the support roller's axis.

[0004] Furthermore, a connecting horizontal plate is fixedly mounted on the lower end of the lower clamping plate, and a short electric cylinder is fixedly mounted on the lower side of the mounting platform, with the telescopic arm of the short electric cylinder fixedly connected to the connecting horizontal plate.

[0005] Furthermore, a horizontal moving plate is slidably mounted on the retaining ring box, and an arc-shaped plate is fixedly mounted at the end of the horizontal moving plate. A retaining groove is fixedly mounted on the inner side of the horizontal moving plate, and the retaining groove engages the retaining ring to move. With the above technical solution, the arc-shaped plate presses against the end retaining ring, and the retaining groove can just engage the retaining ring from both sides, causing the retaining ring to slide on the central axis, but the two retaining grooves will not clamp tightly from both sides.

[0006] Furthermore, a long horizontal electric cylinder is fixedly mounted on the side of the snap ring box, and a connecting block is fixedly mounted on the moving shaft of the long horizontal electric cylinder, and the connecting block is fixedly connected to the snap ring box.

[0007] Furthermore, a sliding groove is fixedly installed at the lower end of the retaining ring box, and a through hole is provided at the lower end of the sliding groove. The retaining ring slides down from the retaining ring box to the bottom of the sliding groove, concentric with the through hole. With the above technical solution, after the retaining ring leaves the central axis, it falls into the rubber pad and slides down along the rubber pad.

[0008] Furthermore, an electric cylinder is fixedly mounted on the upright plate, a bushing is fixedly mounted on the moving shaft of the electric cylinder, and a short shaft is slidably mounted inside the bushing. The short shaft and the bushing push the retaining ring to a designated position.

[0009] Furthermore, a spring is fixedly installed inside the bushing, and the spring is fixedly connected to the short shaft.

[0010] Furthermore, a spring is fixedly mounted at the end of the short shaft, and the short shaft passes through the through hole to hold the snap ring between the spring and the bushing. The inner diameter of the bushing is larger than the diameter of the shaft on the support roller used to install the snap ring, the diameter of the end of the short shaft is smaller than the inner diameter of the bushing, and the outer diameter of the short shaft is smaller than the inner diameter of the bushing.

[0011] Furthermore, a rubber pad is fixedly installed inside the through hole, and the inner diameter of the rubber pad is smaller than that of the retaining circumferential. Through the above technical solution, the bushing can deliver the retaining circumferential to the retaining circumferential groove and lock it in place. When the bushing pushes the retaining circumferential out, it pushes down the spring, opens the retaining circumferential, and the retaining circumferential gradually fits onto the support roller and finally enters the retaining circumferential groove.

[0012] The advantages of this utility model compared with the prior art are: (1) With the technical solution of this utility model, the support roller is already in a stable state when placed on the support frame. It can be more stable by the V-shaped clamping of the upper clamping plate and the lower clamping plate. At the same time, the upper clamping plate and the lower clamping plate can be moved to adjust the height so as to find the axis of the support roller.

[0013] (2) With the technical solution of this utility model, the arc plate presses against the end retaining spring, and the retaining groove can just hold the retaining spring from both sides, causing the retaining spring to slide on the central axis, but the two retaining grooves will not clamp from both sides.

[0014] (3) Through the technical solution of this utility model, after the snap ring leaves the central shaft, it falls into the rubber pad and slides down along the rubber pad.

[0015] (4) Through the technical solution of this utility model, the bushing can deliver the snap ring to the snap ring groove and lock it precisely. When the bushing pushes the snap ring out, it pushes down the spring to open the snap ring. The snap ring is gradually put on the support roller and finally enters the snap ring groove.

Detailed Implementation

[0026] To gain a better understanding of the technical solution and beneficial effects of this utility model, the technical solution and its beneficial effects will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1-9As shown, an automatic assembly machine for support roller clasps includes a mounting platform 1. Four support legs 2 are fixedly mounted on the lower part of the mounting platform 1, located at the four corners. A support frame 6 is fixedly mounted on the mounting platform 1. The support frame 6 is V-shaped, which allows support rollers 12 of different diameters to be stably placed on it. A lower clamping plate 11 is slidably mounted in the middle of the support frame 6. The lower clamping plate 11 is driven by a short electric cylinder 4. A lifting plate 9 is slidably mounted on the support frame 6. An upper clamping plate 10 is fixedly mounted below the lifting plate 9. The lower end of the upper clamping plate 10 is V-shaped, and the upper end of the lower clamping plate 11 is V-shaped. The upper clamping plate 10 and the lower clamping plate 11 together clamp the support roller 12. The upper clamping plate 10 and the lower clamping plate 11 can be moved up and down to adjust the axis. Through the above technical solution, the support roller 12 is already in a stable state when placed on the support frame 6. The V-shaped clamping of the upper clamping plate 10 and the lower clamping plate 11 can make it even more stable. At the same time, both the upper clamping plate 10 and the lower clamping plate 11 can be moved to adjust the height so as to accurately locate the axis of the support roller 12. The lower end of the lower clamping plate 11 is fixedly equipped with a connecting horizontal plate 3. The mounting platform 1 is fixedly equipped with a short electric cylinder 4. The telescopic arm of the short electric cylinder 4 is fixedly connected to the connecting horizontal plate 3. The mounting platform 1 is equipped with an installation assembly to install the retaining spring 27 into the retaining spring groove 29 of the support roller 12.

[0028] In this embodiment, a vertical plate 13 is fixedly mounted on one end of the mounting platform 1, a snap ring box 14 is fixedly mounted on the upper end of the vertical plate 13, a central shaft 20 is fixedly mounted inside the snap ring box 14, and multiple snap rings 27 are sleeved on the central shaft 20.

[0029] In this embodiment, the mounting assembly includes a horizontal moving plate 17, which is slidably mounted on a snap ring box 14. An arc-shaped plate 18 is fixedly mounted at the end of the horizontal moving plate 17. The upper half of the arc-shaped plate 18 is rounded. In other embodiments, it can be a complete arc. The diameter of the arc center is slightly larger than that of the central axis 20. A push spring cylinder 21 is fixedly mounted inside the snap spring box 14. A push spring plate 22 is fixedly mounted on the moving shaft of the push spring cylinder 21. The push spring plate 22 is slidably connected to the central axis 20. The push spring plate 22 always presses against the snap ring 27. The arc-shaped plate 18 presses against the other end of the snap ring 27. The inner diameter of the snap ring 27 is slightly larger than that of the central axis 20. A slot 19 is fixedly mounted on the inner side of the horizontal moving plate 17. The slot 19 locks the snap ring 27 to move. With the above technical solution, the arc plate 18 presses against the end retaining spring 27, and the retaining groove 19 can just hold the retaining spring 27 from both sides, causing the retaining spring 27 to slide on the central shaft 20, but the two retaining grooves 19 will not clamp from both sides.

[0030] In this embodiment, a long horizontal electric cylinder 15 is fixedly mounted on the side of the snap ring box 14. A connecting block 23 is fixedly mounted on the moving shaft of the long horizontal electric cylinder 15, and the connecting block 23 is fixedly connected to the snap ring box 14. A sliding groove 31 is fixedly mounted at the lower end of the snap ring box 14, and a through hole 32 is provided at the lower end of the sliding groove 31. The snap ring 27 slides from the snap ring box 14 to the bottom of the sliding groove 31, concentric with the through hole 32. Through the above technical solution, after the snap ring 27 leaves the central shaft 20, it falls into the rubber pad 30 and slides down along the rubber pad 30. An installation electric cylinder 16 is fixedly mounted on the upright plate 13. A bushing 24 is fixedly mounted on the moving shaft of the installation electric cylinder 16. A short shaft 26 is slidably mounted inside the bushing 24. The short shaft 26 and the bushing 24 push the snap ring 27 to the designated position. A spring 25 is fixedly mounted inside the bushing 24, and the spring 25 is fixedly connected to the short shaft 26. A spring piece 28 is fixedly mounted at the end of the short shaft 26. There are multiple spring pieces 28, which are evenly distributed on the circumference of the short shaft 26. The short shaft 26 passes through the through hole 32 and holds the retaining ring 27 between the spring piece 28 and the bushing 24. A rubber pad 30 is fixedly mounted inside the through hole 32. The inner diameter of the rubber pad 30 is smaller than that of the retaining ring 27. Through the above technical solution, the bushing 24 can deliver the snap ring 27 to the snap ring groove 29 and lock it in place. When the bushing 24 pushes the snap ring 27 out, it pushes down the spring 28 and opens the snap ring 27. The inner diameter of the bushing 24 is slightly larger than the diameter of the shaft on the support roller 12 used to install the snap ring 27. The inner diameter of the bushing 24 is larger than the end diameter of the short shaft 26. The end diameter of the short shaft 26 is smaller than the part of the short shaft 26 inside the bushing 24. The snap ring shaft of the support roller 12 has a clearance fit (the shaft on the support roller 12 where the snap ring 27 is installed is the snap ring shaft, and the diameter of the snap ring shaft is slightly larger than the inner diameter of the snap ring 27, so the inner diameter of the bushing 24 is larger than the short shaft 26, and there is a gap between the two). Therefore, the short shaft 26 presses against one end of the support roller 12, and the bushing 24 can push the snap ring 27 into the snap ring groove 29. The snap ring 27 gradually fits onto the support roller 12 and finally enters the snap ring groove 29.

[0031] Working principle: First, all the retaining rings 27 are placed on the central shaft 20 and arranged neatly. At the same time, the push spring cylinder 21 drives the push spring plate 22 to retract to its limit, and the retaining rings 27 are neatly arranged near the end of the retaining ring box 14. The support roller 12 is placed on the support frame 6, with the middle part of the support roller 12 facing the upper clamping plate 10 and the lower clamping plate 11. Then, the long electric cylinder 7 and the short electric cylinder 4 are activated to clamp the support roller 12, so that both ends of the support roller 12 are in contact with the support frame 6. At the same time, the upper clamping plate 10 and the lower clamping plate 11 clamp the support roller 12. The long horizontal electric cylinder 15 is activated. The long horizontal electric cylinder 15 drives the horizontal moving plate 17 to move closer to the retaining rings 27 through the connecting block 23. Finally, the arc plate 18 is made to fit against the outermost retaining ring 27. At the same time, the retaining groove 19 locks the two sides of the retaining ring 27. The long horizontal electric cylinder 15 is activated in the opposite direction, which will drive the outermost retaining ring 27. Moving outwards, the retaining ring 27 eventually moves to the upper side of the slide groove 31. The retaining ring 27 falls between the two retaining slots 19 and lands at the bottom of the slide groove 31. The installation electric cylinder 16 is activated, which drives the bushing 24 to move outwards, and at the same time drives the short shaft 26 to move. The short shaft 26 passes through the rubber pad 30 and reaches the middle of the retaining ring 27. The diameter of the bushing 24 is larger than that of the retaining ring 27, so the short shaft 26 passes through the retaining ring 27. During the process, it passes through the spring piece 28 and is stuck between the end of the bushing 24 and the spring piece 28. At this time, the bushing 24 drives the retaining ring 27 to pass through the rubber pad 30. The function of the rubber pad 30 is to prevent the retaining ring 27 from tilting at the bottom of the slide groove 31. The rubber pad 30 is made of soft material. The short shaft 26 will press against the end of the support roller 12. At this time, the short shaft 26 stops moving. The bushing 24 continues to move, pushing the retaining ring 27 onto the support roller 12 and finally locking it in the retaining ring groove 29.
