Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, and in particular to a piston pin hole reamer. Background Technology

[0002] The piston is a key component in an engine, and the precision of the piston pin bore directly affects the fit between the piston and the piston pin, thus significantly impacting engine performance. The piston pin bore requires high-precision dimensional tolerances, geometric tolerances (such as cylindricity and roundness), and surface roughness to ensure smooth piston operation within the engine, reduce vibration and wear, and improve engine power output and service life.

[0003] When using existing technology, files that cannot be adjusted in size may not be well-suited for machining objects of different sizes. For example, in machining, when processing inner circular surfaces with different hole diameters or outer contours of different dimensions, a fixed file size cannot effectively perform the filing operation. This necessitates workers to change to different sizes of files to complete the work, increasing the complexity of the operation and reducing work efficiency.

[0004] Therefore, this application provides a piston pin hole reamer to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a piston pin hole reamer.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a piston pin hole reamer, comprising:

[0007] Tool body;

[0008] An adjustment assembly is housed within the tool body. The adjustment assembly includes a sliding chamber slidably connected within the tool body, a first transmission plate slidably connected to the sliding chamber, a sliding shaft slidably connected to the first transmission plate, a second transmission plate rotatably connected to the sliding shaft, a transmission shaft rotatably connected to the second transmission plate, the transmission shaft being fixedly connected to the tool body, the sliding chamber being rotatably connected to the second transmission plate, a transmission frame being fixedly connected to the transmission shaft, a sliding plate being fixedly connected to the transmission frame, an arc-shaped plate being fixedly connected to the first transmission plate, and a cutting blade being fixedly connected to the arc-shaped plate.

[0009] In a preferred embodiment, the sliding plate is provided with a threaded groove, and the tool body is threadedly connected with a bolt, which is slidably connected to the sliding plate.

[0010] The beneficial effects of adopting the above-mentioned further solution are: by opening a threaded groove on the sliding plate, it is convenient to fix the sliding plate during use. When the sliding plate is fully retracted, it is far away from the bolt. After the bolt is tightened on the tool body to clamp the sliding plate, the sliding plate can also be fixed.

[0011] In a preferred embodiment, a fastening shaft is fixedly connected to the cutter, and the fastening shaft is slidably connected to the cutter body.

[0012] The beneficial effects of adopting the above-mentioned further solution are: by fixing a fastening shaft to the cutter, the fastening shaft can squeeze the cutter body when the cutter slides to the surface of the cutter body, thus blocking the cutter body and preventing the debris cut by the cutter from entering the cutter body. Moreover, the cutter can be squeezed during cutting so that it will not be displaced during cutting.

[0013] In a preferred embodiment, a sliding hole is provided on the side of the tool body near the sliding chamber, and the transmission frame is slidably connected to the sliding hole on the tool body.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by opening a sliding hole on the tool body, the sliding of the transmission frame is facilitated.

[0015] In a preferred embodiment, the second transmission plate is rotatably connected to the transmission shaft via a rotating shaft, and the end of the second transmission plate away from the transmission shaft is rotatably connected to the sliding chamber via a rotating shaft.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting the second transmission plate to be rotatably connected to the transmission shaft through the rotating shaft, when the sliding chamber slides, it will drive the second transmission plate to rotate, thereby driving the sliding shaft to slide, so that the first transmission plate slides on the sliding chamber.

[0017] In a preferred embodiment, a slot is provided in the tool body, and the sliding chamber and the arc-shaped plate are slidably connected in the slot in the tool body.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting up an arc-shaped plate, it is convenient for the first transmission plate to drive the arc-shaped plate to slide.

[0019] In a preferred embodiment, the first transmission plate has an arc-shaped slot, and the sliding shaft is slidably connected within the arc-shaped slot on the first transmission plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by opening an arc-shaped slot on the first transmission plate, it is convenient for the sliding shaft to slide during use. When the sliding shaft slides down on the first transmission plate, it can drive the arc-shaped slot to slide in the sliding chamber.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, when the size of the cutter needs to be adjusted, the sliding plate is moved, causing it to move the second transmission plate via the sliding chamber. One end of the second transmission plate presses down on the transmission shaft, causing the sliding shaft to slide on the first transmission plate, which in turn drives the first transmission plate to slide down in the sliding chamber. Finally, the arc-shaped plate drives the cutter to slide outward, thus adjusting the cutter length. Unlike traditional files, there is no need to frequently change different sizes of tools. This invention can flexibly adapt to different sized processing objects, improving processing efficiency. At the same time, the cutter length can be adjusted as needed, which helps to accurately control the filing amount and ensure processing accuracy. The fastening shaft on the cutter can both compress and seal the cutter body to prevent debris from entering and stabilize the cutter to prevent cutting displacement. Furthermore, the sliding holes on the cutter body, the reasonable rotating shaft connection between various components, and the slotted design ensure smooth coordination of various components during adjustment, optimize the user experience, and solve the problem of frequent tool replacement required in the prior art.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1-5 As shown, this utility model provides a technical solution: a piston pin hole reamer, comprising:

[0033] Tool body 1;

[0034] Adjustment component 2 is placed inside the tool body 1. Adjustment component 2 includes a sliding chamber 21 slidably connected inside the tool body 1. A first transmission plate 22 is slidably connected to the sliding chamber 21. A sliding shaft 24 is slidably connected to the first transmission plate 22. A second transmission plate 23 is rotatably connected to the sliding shaft 24. A transmission shaft 26 is rotatably connected to the second transmission plate 23. The transmission shaft 26 is fixedly connected to the tool body 1. The sliding chamber 21 is rotatably connected to the second transmission plate 23. A transmission frame 25 is fixedly connected to the transmission shaft 26. A sliding plate 27 is fixedly connected to the transmission frame 25. An arc-shaped plate 28 is fixedly connected to the first transmission plate 22. A cutting blade 29 is fixedly connected to the arc-shaped plate 28.

[0035] In this invention, when the size of the cutter 29 needs to be adjusted, the sliding plate 27 is moved, causing it to move the second transmission plate 23 via the sliding chamber 21. One end of the second transmission plate 23 presses down on the transmission shaft 26, causing the sliding shaft 24 to slide on the first transmission plate 22, which in turn causes the first transmission plate 22 to slide down in the sliding chamber 21. Finally, the arc plate 28 causes the cutter 29 to slide outward, thus achieving the length adjustment of the cutter 29. Unlike traditional files, there is no need to frequently change different specifications of tools. It can flexibly adapt to different sized processing objects, improving processing efficiency. At the same time, the length of the cutter 29 can be adjusted as needed to accurately control the filing amount and ensure processing accuracy. The fastening shaft 210 on the cutter 29 can both squeeze and seal the cutter body 1 to prevent debris from entering and stabilize the cutter to avoid cutting displacement. Furthermore, the sliding hole on the cutter body 1, the reasonable rotating shaft connection between various components, and the slot design ensure smooth coordination of various components during the adjustment process and optimize the user experience.

[0036] Further as Figures 1 to 5 As shown, the sliding plate 27 has a threaded groove, and the tool body 1 is threaded with a bolt. The bolt on the tool body 1 is slidably connected to the sliding plate 27. By having a threaded groove on the sliding plate 27, it is convenient to fix the sliding plate 27 during use. When the sliding plate 27 is fully retracted, it is far away from the bolt. After the bolt is tightened on the tool body 1 to clamp the sliding plate 27, the sliding plate 27 can also be fixed.

[0037] A fastening shaft 210 is fixedly connected to the cutter 29. The fastening shaft 210 is slidably connected to the cutter body 1. By fixing the fastening shaft 210 to the cutter 29, the fastening shaft 210 can squeeze the cutter body 1 when the cutter 29 slides to the surface of the cutter body 1, thus sealing the cutter body 1 and preventing the debris cut by the cutter 29 from entering the cutter body 1. Furthermore, the cutter can be squeezed during cutting to prevent it from shifting.

[0038] A sliding hole is provided on the side of the tool body 1 near the sliding chamber 21. The transmission frame 25 is slidably connected in the sliding hole on the tool body 1. The sliding hole on the tool body 1 facilitates the sliding of the transmission frame 25.

[0039] The second transmission plate 23 is rotatably connected to the transmission shaft 26 via a rotating shaft. One end of the second transmission plate 23 away from the transmission shaft 26 is rotatably connected to the sliding chamber 21 via a rotating shaft. By setting the second transmission plate 23 to be rotatably connected to the transmission shaft 26 via a rotating shaft, when the sliding chamber 21 slides, it will drive the second transmission plate 23 to rotate, thereby driving the sliding shaft 24 to slide, so that the first transmission plate 22 slides on the sliding chamber 21.

[0040] The tool body 1 has a slot, and the sliding chamber 21 and the arc plate 28 are slidably connected in the slot of the tool body 1. The arc plate 28 facilitates the sliding of the arc plate 28 by the first transmission plate 22.

[0041] The above scheme also has the problem of not clearly defining the specific sliding method between the sliding shaft 24 and the first transmission plate 22, such as... Figures 2 to 5 As shown, an arc-shaped slot is provided on the first transmission plate 22, and the sliding shaft 24 is slidably connected in the arc-shaped slot on the first transmission plate 22. The arc-shaped slot on the first transmission plate 22 facilitates the sliding of the sliding shaft 24 during use. When the sliding shaft 24 slides downward on the first transmission plate 22, it can drive the arc-shaped slot to slide in the sliding chamber 21.

[0042] Working principle: such as Figure 1-4 As shown,

[0043] In use, when it is necessary to adjust the size of the cutter 29, the sliding plate 27 is moved by moving the sliding plate 27, which drives the second transmission plate 23 to move through the sliding chamber 21. The end of the second transmission plate 23 away from the sliding chamber 21 then presses up and down on the transmission shaft 26, causing the sliding shaft 24 to slide on the first transmission plate 22, which drives the first transmission plate 22 to slide up and down in the sliding chamber 21, causing the arc plate 28 to slide outward, so that the cutter 29 is driven to slide out, thereby realizing the adjustment of the length of the cutter 29 on the tool body 1;

[0044] Then, a bolt is screwed into the sliding plate 27 to fix the sliding plate 27.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
