Description

Technical Field

[0001] This utility model relates to the field of cleaning technology, and in particular to an adjustable honing cleaning rod for deep hole cleaning. Background Technology

[0002] The cylinder body of the compression cylinder has deep plunger holes machined for mounting the cylinder. The machining process of the plunger holes includes rough machining, heat treatment, finish machining, and honing. After honing, the plunger holes will have residual metal sludge from the honing process; some products, after heat treatment such as nitriding, also have a lot of impurities on the surface, and after honing, a white, shiny layer will adhere to the hole wall. Therefore, in order to improve assembly accuracy, deep holes like plunger holes need to be cleaned after machining.

[0003] Currently, manual scrubbing with cleaning fluid is the primary method, but this relies on manual operation of the cleaning brush. For deep-hole structures like plunger orifices, the cleaning brush struggles to reach the bottom. Furthermore, it cannot effectively remove debris adhering to the hole walls, resulting in extremely low cleaning efficiency and inconsistent quality. Additionally, the cleaning fluid exhibits an inverted conical decay as it flows through deep holes, causing particulate impurities to easily deposit at the bottom or on the walls. Even high-pressure flushing cannot completely cover the inner walls of the deep holes. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the purpose of this utility model is to provide an adjustable honing cleaning rod for deep hole cleaning.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An adjustable honing cleaning rod for deep hole cleaning includes a push rod connected to a honing machine. A honing cylinder is movably sleeved on the outer periphery of the push rod, and a cleaning head is sleeved on the end of the honing cylinder. A slider is axially movably embedded in the end of the push rod located inside the honing cylinder. The slider passes through the honing cylinder and contacts the cleaning head. The push rod moves telescopically inside the honing cylinder, causing the slider to move in the opposite direction to increase or decrease the diameter of the cleaning head, thereby matching the diameter of the cleaning head with the inner diameter of the deep hole to be cleaned.

[0006] In a further embodiment, the push rod includes a rod body, one end of which is provided with an external thread for connection with a honing machine; the outer wall of the other end of the rod body is provided with a groove along its axial direction that is adapted to the slider, so that the slider moves along the groove.

[0007] In a further embodiment, the slide groove is provided in three parts, evenly distributed on the outer periphery of the rod; the slider is a trapezoidal structure with one end face being a plane and the other end face being an inclined plane.

[0008] In a further embodiment, the push rod is connected between the honing cylinders by a limiting device to limit the extension and retraction movement of the push rod inside the honing cylinder.

[0009] In a further embodiment, the limiting device includes a limiting bolt and a limiting block, and a limiting groove is formed on the outer surface of the push rod along its axial direction; the limiting bolt passes through the honing cylinder and the limiting groove in sequence and is then threadedly connected to the limiting block, which is movably located within the limiting groove, so that the push rod carries the limiting device and moves axially within the limiting groove. When tightened, the push rod is fixed to the honing cylinder.

[0010] In a further embodiment, the honing cylinder includes a cylinder body, one end of which is fixedly provided with a connector, and a limiting groove for the slider to pass through is provided on the side wall of the connector.

[0011] In a further embodiment, a limiting ring is fixed on the cylinder, and the limiting ring has a connecting hole.

[0012] In a further embodiment, the outer diameter of the cylinder is larger than the outer diameter of the connector, forming a step at the connection point; the cleaning head is fitted over the connector and fixedly connected to the connector by fixing bolts; the connector has a second mounting hole.

[0013] In a further embodiment, the cleaning head includes a cylindrical cleaning head body, with convex ridges fixedly provided at equal intervals on its outer wall, and a mounting hole is provided on the cleaning head body located between two adjacent convex ridges.

[0014] The adjustable honing cleaning rod of this application has a long structure, suitable for cleaning deep holes. The push rod and the honing cylinder are connected by a limiting device. Loosening the limiting bolt allows the push rod to extend and retract within the honing cylinder, thus adjusting the positions of the push rod and the honing cylinder. When the limiting bolt is at one end of the limiting groove and the push rod is at its longest, the diameter of the cleaning head is at its smallest; when the limiting bolt is at the other end of the limiting groove and the push rod is at its shortest, the diameter of the cleaning head is at its largest. Tightening the limiting bolt then fixes the push rod and the honing cylinder in place.

[0015] In this application, a slider is provided between the push rod and the cleaning head. The slider passes through the honing cylinder and contacts the cleaning head, pushing the push rod. The slider is limited by the honing cylinder and moves in the opposite direction relative to the push rod, thereby increasing or decreasing the diameter of the cleaning head so that the diameter of the cleaning head matches the inner diameter of the deep hole to be cleaned.

[0016] The cleaning head of this application is made of rubber, which has high elasticity, is not easy to damage the surface of the workpiece, has high tolerance to honing oil, reduces replacement costs, is resistant to high temperature, and is not easy to stick to the surface of the workpiece. The cleaning head of this application is provided with axially protruding ridges to reduce the contact area between the cleaning head and the inner wall of the deep hole; the protruding ridges can also scrape off the impurities adhering to the inner wall of the deep hole by rotation, and the grooves formed between adjacent protruding ridges can better allow dirt to fall out of the grooves, avoiding scratches on the inner wall surface of the deep hole caused by the friction between the impurities embedded on the surface of the cleaning head and the inner wall of the deep hole.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] See Figure 1-7This embodiment provides an adjustable honing cleaning rod for deep hole cleaning, including a push rod 1 connected to a honing machine. A honing cylinder 2 is movably fitted around the outer periphery of the push rod 1, meaning the push rod 1 can extend and retract inside the honing cylinder 2. A cleaning head 3 is fitted at the end of the honing cylinder 2 for cleaning the inner wall of the deep hole. A slider 4 is axially fitted at the end of the push rod 1 located inside the honing cylinder 2, meaning the slider 4 can move axially along the push rod 1. The slider 4 contacts the cleaning head 3 after passing through the honing cylinder 2. The extension and retraction of the push rod 1 inside the honing cylinder 2 drives the slider 4 to move in the opposite direction, increasing or decreasing the diameter of the cleaning head 3, thereby matching the diameter of the cleaning head 3 with the inner diameter of the deep hole to be cleaned.

[0021] In this embodiment, the honing machine is an existing product, and this application does not involve its specific structure, so it will not be described in detail. In use, the adjustable honing cleaning rod of this application is simply installed on the honing machine. Specifically, after connecting one end of the push rod 1 to the honing machine, the end with the cleaning head 3 is inserted into the deep hole to be cleaned, reaching the area that needs cleaning. The length of the adjustable honing cleaning rod should be greater than the depth of the deep hole, and its outer diameter should be slightly smaller than the inner diameter of the deep hole to facilitate entry, exit, and rotation. Pushing the push rod 1 causes the slider 4, which passes through the honing cylinder 2, to move in the opposite direction relative to the push rod 1, thereby increasing the circumferential outer diameter of the slider 4 on the push rod 1. This increases the diameter of the cleaning head 3, causing the cleaning head 3 to expand radially, thus pressing its outer wall tightly against the inner wall of the deep hole with a certain positive pressure. The honing machine rotates the adjustable honing and cleaning rod, and the whole machine can also reciprocate axially, thereby scraping off the debris adhering to the inner wall of the deep hole and achieving the purpose of cleaning.

[0022] like Figure 3 As shown, the push rod 1 includes a rod body 11. One end of the rod body 11 is provided with an external thread 14 for connection with a honing machine. The outer wall of the other end of the rod body 11 is provided with a groove 12 that matches the slider 4 along its axial direction, so that the slider 4 can move along the groove 12.

[0023] In a specific embodiment, three grooves 12 are provided, evenly distributed around the outer periphery of the rod 11, thereby uniformly expanding the diameter of the cleaning head; the slider 4 is a trapezoidal structure with one end face being flat and the other end face being inclined. The bottom surface of the groove 12 is also an inclined structure, extending from the end of the rod 11 towards the end of the external thread 14, and the depth gradually decreases (e.g., ...). Figure 3 As shown, when slider 4 moves toward the end of external thread 14, the outer radius formed by the three sliders 4 increases. When slider 4 moves toward the end of groove 12, the outer radius formed by the three sliders 4 decreases until it matches the radius of rod 11.

[0024] In order to limit the extension and retraction of push rod 1, push rod 1 is connected between honing cylinders 2 by a limiting device to limit the extension and retraction of push rod 1 inside honing cylinder 2.

[0025] In this embodiment, the limiting device includes a limiting bolt 5 and a limiting block (not shown in the figure). A limiting groove 13 is formed on the outer surface of the push rod 1 along its axial direction. The limiting bolt 5 passes through the honing cylinder 2 and the limiting groove 13 in sequence and is threadedly connected to the limiting block, which is movably located in the limiting groove 13. This allows the push rod 1 to move axially within the limiting groove 13 with the limiting device, and also allows the push rod 1 and the honing cylinder 2 to be fixed in the tightened state. That is, the length of the limiting groove 13 restricts the length of the movement path of the push rod 1, while the push rod 1 and the honing cylinder 2 do not move circumferentially. Therefore, when the honing machine is working, it will rotate the push rod 1 and the honing cylinder 2 together.

[0026] like Figure 4 As shown, the honing cylinder 2 includes a cylinder body 21, with a connector 22 fixedly attached to one end of the cylinder body 21. A limiting slot 23 for the slider 4 to pass through is provided on the side wall of the connector 22. The limiting slot 23 is adapted to the outer diameter of the slider 4 and is used to limit the slider 4.

[0027] Specifically, a limiting ring 25 is fixedly provided on the cylinder 21, and the limiting ring 25 has a connecting hole 26. The limiting ring 25 protrudes from the outer wall of the cylinder 21, that is, the wall thickness is increased at this point. The connecting hole 26 is opened here for installing the limiting bolt. That is, the limiting bolt 5 passes through the connecting hole 26 and the limiting groove 13 in sequence and is fixedly connected to the limiting block, thereby increasing the stress strength of the cylinder 21.

[0028] Specifically, the outer diameter of the cylinder 21 is larger than the outer diameter of the connector 22, forming a step at the connection point. The cleaning head 3 is fitted over the connector 22, and the step precisely limits the movement of the cleaning head 3 along the axial direction of the honing cylinder 2. The cleaning head 3 is fixedly connected to the connector 22 by fixing bolts 6. Specifically, the connector 22 has a second mounting hole 24, and the cleaning head 3 has a first mounting hole 33. The fixing bolts 6 pass through the first mounting hole 33 and the second mounting hole 24 in sequence to fix the cleaning head 3 to the connector 22.

[0029] like Figure 5 As shown, the cleaning head 3 includes a cylindrical cleaning head body 31, with protrusions 32 fixedly arranged at equal intervals on its outer wall, and a mounting hole 33 is provided on the cleaning head body 31 located between two adjacent protrusions 32.

[0030] In this embodiment, four protruding ridges 32 can be evenly arranged, protruding from the cleaning head body 31. The arrangement of the protruding ridges 32 can reduce the contact area between the cleaning head 3 and the inner wall of the deep hole. The protruding ridges 32 can also act as scrapers, scraping off the impurities adhering to the inner wall of the deep hole by rotation. Furthermore, the groove formed between adjacent protruding ridges 32 can better allow dirt to fall out of the groove, avoiding scratches on the inner wall surface of the deep hole caused by the friction between the dirt embedded on the surface of the cleaning head 3 and the inner wall of the deep hole.

[0031] In addition, the cleaning head 3 in this embodiment is made of rubber, which is not easy to scratch the hole wall of the deep hole and can be cleaned.

[0032] In use, after connecting one end of the push rod 1 to the honing machine, operate the limiting device on the limiting ring 25, that is, loosen the limiting bolt 5 to adjust the position of the push rod 1 and the honing cylinder 2, so that the diameter of the cleaning head 3 is smaller than the inner diameter of the deep hole to be cleaned (e.g., Figure 6 (as shown), and then tighten the limiting bolt 5 to fix the push rod 1 and the honing cylinder 2.

[0033] Insert the cleaning head 3 into the deep hole to be cleaned, reaching the area requiring cleaning. Then loosen the limiting bolt 5 and push the push rod 1. Since the honing cylinder 2 remains stationary, the slider 4, which passes through the honing cylinder 2, moves in the opposite direction relative to the push rod 1, increasing the circumferential outer diameter of the slider 4 on the push rod 1, thereby increasing the diameter of the cleaning head 3 (e.g., Figure 7 As shown), even if the cleaning head 3 expands radially, its outer wall will press tightly against the inner wall of the deep hole with a certain positive pressure. Then tighten the limiting bolt 5 to fix the push rod 1 and the honing cylinder 2.

[0034] The honing machine drives the adjustable honing cleaning rod to rotate, and at the same time, it can also make axial reciprocating motion, thereby scraping off the debris adhering to the inner wall of the deep hole and dropping it from the groove formed between the adjacent protrusions 32 on the cleaning head 3, achieving the purpose of cleaning and avoiding scratches on the surface of the inner wall of the deep hole.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
