Description

Technical Field

[0001] This utility model relates to the field of bearing disassembly technology, and in particular to a tooling for disassembling the bearings of yarn wheel reels. Background Technology

[0002] On a fiberglass production line, the yarn cart is the core carrier for yarn roll transfer. Its operational stability directly affects the continuity of the production process. Under long-term high-load operation, the bearing system in the yarn cart hub is prone to problems such as lubrication failure, ball wear, or cage breakage. When the bearing jams or has excessive clearance, the yarn cart will not only generate abnormal vibration and noise, but also cause deviation in its travel trajectory. This can cause yarn roll collision and deformation at best, and trigger a chain reaction of failures in the entire transportation system at worst.

[0003] The currently used yarn spinning machines have wheels with two bearings connected by a sleeve. When replacing the bearings, the wheel body is usually clamped in a bench vise, and the bearing is knocked out by directly striking it with a chisel or copper rod. Because the fitter's tools are of general specifications and do not perfectly match the size of the bearings, this leads to low maintenance efficiency or safety hazards. Especially with a large number of yarn spinning machines and a huge amount of maintenance work every day, maintenance personnel need to repeat the knocking operation hundreds of times, which greatly increases the labor intensity, reduces the accuracy of operation, and significantly increases the safety risks such as tool slippage and flying fragments. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tooling for disassembling yarn wheel bearings. It solves the problem that workers need to perform a large number of repetitive hammering operations when disassembling bearings, which is labor-intensive and can lead to decreased operational accuracy and safety accidents.

[0005] According to an embodiment of this utility model, a tooling for disassembling a yarn wheel bearing includes a base and a hydraulic cylinder. A collection groove is provided on one side of the base, a baffle is fixedly provided on the top of the base, and a partition is provided at the bottom of the baffle. The space enclosed by the partition and the baffle is for placing the wheel. A through hole is opened in the middle of the partition. Mounting plates are symmetrically provided on both sides of the base. A column is provided vertically upward at the end of each mounting plate away from the base. A top plate is provided between the two columns. The hydraulic cylinder is fixedly mounted on the top plate. A first push rod is fixedly provided vertically downward at the output end of the hydraulic cylinder. A second push rod is fixedly provided at the bottom of the first push rod.

[0006] Compared with the prior art, this utility model has the following advantages: By placing the wheel with the bearing to be removed flat on the partition, the hydraulic cylinder on the top plate extends downward to drive the second push rod to abut against the sleeve and knock the sleeve and the lower bearing out. After knocking out the sleeve and the lower bearing together, the hydraulic cylinder returns to the zero position, the wheel is flipped, and the hydraulic cylinder is restarted to drive the first push rod to move downward, so that the second push rod knocks out the bearing. In this process, the worker only needs to pick up the wheel and flip it. While saving labor intensity, the centering effect of the enclosure also ensures that the wheel will not deviate, and the bearing and sleeve are accurately knocked out.

[0007] Furthermore, corresponding openings are provided on the fences and partitions.

[0008] Furthermore, it also includes a thickened plate and a first bolt. The thickened plate is annular in shape with an opening on one side. Several first threaded holes are provided on the inner wall of the enclosure. A first countersunk hole corresponding to the first threaded hole is provided on the inner wall of the thickened plate. The first bolt is screwed into the first threaded hole after being inserted into the countersunk hole.

[0009] Furthermore, it also includes a first thickened ring, a second thickened ring, and a second bolt. The inner walls of the first thickened ring and the second thickened ring are provided with several second countersunk holes. The first push rod and the second push rod are provided with second threaded holes corresponding to the second countersunk holes. The second countersunk holes are for the second bolt to pass through and be screwed into the second threaded holes.

[0010] Furthermore, both the bottom of the first thickened ring and the second thickened ring are provided with rubber sleeves.

[0011] Furthermore, a collection frame is slidably provided inside the collection tank, and a handle is fixedly provided on the side of the collection frame away from the collection tank.

[0012] Furthermore, the support column is an electrically operated telescopic pole. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-5As shown in the figure, this utility model embodiment proposes a tooling for disassembling the bearing of a yarn wheel, including a base 1 and a hydraulic cylinder 7. A collection groove is provided on one side of the base 1, a baffle 2 is fixedly provided on the top of the base 1, and a partition 3 is provided at the bottom of the baffle 2. The space enclosed by the partition 3 and the baffle 2 is for placing the wheel 21. A through hole is opened in the middle of the partition 3. Mounting plates 4 are symmetrically provided on both sides of the base 1. A column 5 is provided vertically upward at the end of each mounting plate 4 away from the base 1. A top plate 6 is provided between the two columns 5. The hydraulic cylinder 7 is fixedly installed on the top plate 6. A first push rod 8 is fixedly provided vertically downward at the output end of the hydraulic cylinder 7. A second push rod 9 is fixedly provided at the bottom of the first push rod 8. The first push rod 8 and the second push rod 9 are coaxially arranged. It should be noted that the diameter of the second push rod 9 is smaller than the diameter of the first push rod 8. In this embodiment, the diameter of the first push rod 8 is the same as the installation diameter of the bearing 22 (φ20), and the diameter of the second push rod 9 is the same as the inner diameter of the bearing 22 (φ15). When removing the bearing 22 from the wheel 21, the wheel 21 is placed flat on the partition 3. The enclosure 2 is annular, and the inner diameter of the enclosure 2 is the same as the outer diameter of the wheel 21, so that the wheel 21 will not move much in the horizontal direction after being placed on the partition 3. The enclosure 2 is used to position the wheel 21. Then, the hydraulic cylinder 7 is activated. The output end of the hydraulic cylinder 7 pushes the first push rod 8 and the second push rod 9 downward. The second push rod 9 will first push the sleeve 23 and the bearing 22 below to fall down, and fall into the collection groove through the through hole on the partition 3. (It should be noted that the sleeve 23 is thicker in the middle and thinner at both ends.) The structure consists of a step at both ends of the sleeve 23, with two bearings 22 fitted onto the steps. When the sleeve 23 moves downward, the steps push the lower bearing 22 downward. Then, the hydraulic cylinder 7 drives the first push rod 8 and the second push rod 9 back to the zero position. The worker flips the wheel 21 180 degrees, so that the bearing 22, which was originally on top, is on the bottom. The hydraulic cylinder 7 is then activated again, so that the bottom of the first push rod 8 at the output end of the hydraulic cylinder 7 abuts against the bearing 22, knocking the bearing 22 off the wheel 21. (The wheel 21 usually has a limit structure that restricts the bearings 22 from moving closer to each other, so the wheel 21 needs to be flipped 180 degrees. If the wheel 21 does not have a limit structure, it can be knocked off by repeatedly striking the first push rod 8 without flipping the wheel 21.) Preferably, the stroke of the hydraulic cylinder 7's output end can be set by a PLC programmable logic controller. With this device, workers only need to place the wheel 21 flat on the partition 3 and start the hydraulic cylinder 7 to quickly and effortlessly remove the bearing 22 from the wheel 21, significantly reducing labor intensity. The positioning of the wheel 21 by the enclosure 2 ensures that the bearing 22 is accurately knocked out, avoiding safety accidents.

[0021] like Figure 1 and Figure 3As shown, both the enclosure 2 and the partition 3 are provided with corresponding notches. In this embodiment, the notches of the enclosure 2 and the partition 3 face the direction of the collection groove on the base 1. The notches are designed so that when the wheel 21 needs to be flipped, one side of the wheel 21 will be exposed, which is convenient for workers to perform the flipping operation.

[0022] like Figure 3 and Figure 4 As shown, further, it also includes a thickened plate 10 and a first bolt. The thickened plate 10 is annular in shape with an opening on one side. The inner wall of the enclosure 2 has several first threaded holes, and the inner wall of the thickened plate 10 has first countersunk holes corresponding to the first threaded holes. The first bolt passes through the countersunk hole and is screwed into the first threaded hole. The opening on the thickened plate 10 is to correspond to the notches on the enclosure 2 and the partition 3. In this embodiment, three first countersunk holes are provided at equal intervals on the inner wall of the thickened plate 10. For wheels 21 of different diameters, the size of the accommodating space enclosed by the enclosure 2 and the partition 3 needs to be adjusted to facilitate the positioning of the wheel 21. The worker makes the corresponding thickened plate 10 according to the diameter of the wheel 21, and connects the thickened plate 10 to the enclosure 2 with the first bolt. The first countersunk hole can prevent the first bolt from interfering with the wheel 21. Preferably, the first bolt is an internal hex bolt.

[0023] like Figure 3-5 As shown, further, it also includes a first thickening ring 11, a second thickening ring 12, and a second bolt. The inner walls of both the first thickening ring 11 and the second thickening ring 12 are provided with several second countersunk holes. The first push rod 8 and the second push rod 9 are each provided with a second threaded hole corresponding to the second countersunk hole. The second countersunk hole allows the second bolt to pass through and be screwed into the second threaded hole. In this embodiment, the first thickening ring 11, the second thickening ring 12, and the thickening plate 10 serve the same function. Specifically, when striking bearings 22 and sleeves 23 of different diameters, the first thickening ring 11 is connected to the first push rod 8, and the second thickening ring 12 is connected to the second push rod 9, thereby adaptively increasing the thickness of the first push rod 8 and the second push rod 9 to accommodate bearings 22 and sleeves 23 of different diameters, improving applicability. Preferably, the second bolt is also an internal hex bolt.

[0024] like Figure 5 As shown, both the first thickened ring 11 and the second thickened ring 12 are further provided with rubber sleeves 13 at their bottoms. When the first push rod 8 and the second push rod 9 strike the bearing 22 and the sleeve 23, the rubber sleeves 13 protect the bearing 22 and the sleeve 23, preventing the removed bearing 22 and sleeve 23 from deforming, which would be detrimental to subsequent cost reduction and efficiency improvement.

[0025] like Figure 3 and Figure 4As shown, a collection frame 14 is slidably provided inside the collection tank, and a handle 15 is fixedly provided on the side of the collection frame 14 away from the collection tank. The collection frame 14 collects the fallen bearings 22 and sleeves 23, preventing them from rolling to the outside and being lost or stepped on by passing workers, thus causing a safety accident. Preferably, a limiting plate can also be provided on the base 1 to restrict the collection frame 14 from moving freely inside the collection tank.

[0026] Furthermore, the column 5 is an electric telescopic rod. In this embodiment, the column 5 is an electric telescopic rod, and the extension of the two columns 5 can push the top plate 6 to rise, providing a larger operating space for workers to retrieve the wheel 21. Through the PLC programmable controller, the electric telescopic rod and the hydraulic cylinder 7 work together to achieve the following: after the wheel 21 is placed on the partition 3, the electric telescopic rod and the hydraulic cylinder 7 are activated. The top plate 6 reaches the predetermined height as the electric telescopic rod shortens. At this time, the hydraulic cylinder 7 drives the second push rod 9 to extend and shorten back and forth to achieve a "knocking" effect. Then, the electric telescopic rod drives the top plate 6 to slowly descend, thereby allowing the second push rod 9 to knock the sleeve 23 back and forth, knocking the sleeve 23 and the lower bearing 22 off the wheel 21. After the electric push rod retracts to the predetermined position (at which point the sleeve 23 and the lower bearing 22 can be knocked out), the electric push rod extends to the zero position and pauses for a period of time to allow workers enough time to flip or replace the wheel 21. The subsequent process is to knock out the other bearing 22, which will not be described in detail here.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
