[0002] At present, most of the internal roller burnishing tools on the market are designed with a single specification (such as the attached Figure 1 ), that is, each diameter corresponds to a specific tool. This design not only requires a large number of tools of different sizes to meet production needs, but also makes the manufacturing cost of large-sized tools very high. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An adjustable inner hole roller polishing knife is provided with a main shaft, an inner hole roller polishing knife adjustment mechanism is fixedly connected to the main shaft, two groups of cutting tools are arranged on the inner hole roller polishing knife adjustment mechanism, the inner hole roller polishing knife adjustment mechanism can adjust the telescopic position of the cutting tool, and an outer diameter roller polishing knife is fixedly arranged on the cutting tool.

[0006] Furthermore, two slide grooves are provided in the middle of the inner hole roller polishing knife adjustment mechanism, and the knife can be embedded in the slide grooves and can slide in the slide grooves.

[0007] Furthermore, a plurality of threaded holes are opened outward on the inner wall of the chute, and bolts are threadedly connected to the threaded holes. The tool can be fixed in the chute by tightening the bolts inward.

[0008] Furthermore, the inner hole roller polishing knife adjustment mechanism is provided with circumferential size scales on both sides, and an adjustment threaded hole is opened in the middle of the circumferential size scale. The adjustment threaded hole passes through the slide groove, and the adjustment threaded hole is threadedly connected with an adjustment bolt.

[0009] Furthermore, the tool is provided with a plurality of embedding grooves, the size and position of the embedding grooves are adapted to the threaded holes, and the bolts can be inserted into the embedding grooves through the threaded holes; a linear size scale is provided on the front of the inner hole roller polishing knife adjustment mechanism.

Four groups of positioning threaded holes are opened on the main shaft, and a main shaft embedding groove is opened on the back of the inner hole roller polishing knife adjustment mechanism. The shape of the main shaft embedding groove and the end of the main shaft is set to be a truncated cone, and the positioning bolts are threadedly connected to the positioning threaded holes.

[0011] Beneficial effects:

[0012] The design proposed in this utility model significantly reduces the need for tools of varying sizes, avoiding the high costs associated with traditional single-size tools.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 2-5 As shown, an adjustable inner hole roller polishing knife is provided with a main shaft 1, an inner hole roller polishing knife adjustment mechanism 2 is fixedly connected to the main shaft 1, two groups of cutting tools 3 are provided on the inner hole roller polishing knife adjustment mechanism 2, the inner hole roller polishing knife adjustment mechanism 2 can adjust the telescopic position of the cutting tool 3, and an outer diameter roller polishing knife 31 is fixedly provided on the cutting tool 3.

[0022] In this embodiment, two slide grooves 21 are provided in the middle of the inner hole roller polishing knife adjustment mechanism 2 . When in use, the knife 3 can be embedded in the slide groove 21 and can slide in the slide groove 21 .

[0023] In this embodiment, six threaded holes 22 are opened outward on the inner wall of the slide groove 21, and bolts 23 are threadedly connected to the threaded holes 22. When in use, the bolts 23 are tightened inward to fix the tool 3 in the slide groove 21. When loosened, the tool 3 can continue to slide in the slide groove 21.

[0024] In this embodiment, circumferential size scales 25 are provided on both sides of the inner hole roller polishing knife adjustment mechanism 2, and an adjustment threaded hole 24 is opened in the middle of the circumferential size scale 25. The adjustment threaded hole 24 passes through the slide groove 21, and the adjustment threaded hole 24 is threadedly connected with an adjustment bolt 241. When in use, the distance between the tool 3 and the inner wall of the side of the slide groove 21 is adjusted by rotating the adjustment bolt 241.

[0025] Two groups of through holes 26 are set through the inner wall of the slide groove 21 to the rear, and positioning bolts 261 are provided on the through holes 26. Four groups of positioning threaded holes 11 are opened on the main shaft 1, and a main shaft embedding groove 27 is opened on the back of the inner hole roller polishing knife adjustment mechanism 2. The shape of the main shaft embedding groove 27 and the end of the main shaft 1 is set to be a truncated cone, and the positioning bolts 261 are threadedly connected to the positioning threaded holes 11.

[0026] Working Principle: By default, the cutter 3 is in its initial position within the chute 21. To adjust the cutter's extension to accommodate a hole of varying diameter, the user can rotate the adjustment bolt 241 to adjust the distance between the cutter 3 and the inner wall of the chute 21, thereby moving the cutter 3 along the chute 21 to the appropriate position. Once the desired position is reached, the cutter 3 is secured in the chute 21 by tightening the bolt 23. This completes the adjustment of the cutter's position. The distance between the cutter 3 and the inner wall of the chute 21 effectively adjusts the inner diameter of the two outer diameter roller burnishers 31.

[0027] When the tool needs to be replaced or the fixed position of the tool needs to be adjusted, it is only necessary to loosen the bolt 23 to allow the tool 3 to slide along the slide 21. In this way, the position of the tool can be adjusted quickly and accurately to meet the needs of internal hole processing of different sizes.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in this invention is defined by the appended claims and their equivalents.

[0029] Example 2

[0030] like Figure 6 As shown, this embodiment is basically the same as embodiment 1, with the difference being that: the circumferential size scale 25, the adjusting threaded hole 24, and the adjusting bolt 241 are cancelled, and four embedding grooves 32 are directly provided on the tool 3. The size and position of the embedding grooves 32 are adapted to the threaded hole 22, and the bolts 23 can pass through the threaded hole 22 and be embedded in the embedding grooves 32; a linear size scale 20 is provided on the front of the inner hole roller polishing knife adjustment mechanism 2.

[0031] Specifically, when adjusting the tool's position, first loosen the bolt to allow the tool to slide freely within the chute. Once the tool has reached the desired position, tighten the bolt again. The bolt will then pass through the positioning threaded hole on the inner wall of the chute and engage the retaining groove on the tool, securing the tool. This design also allows the user to adjust the tool's position as needed to accommodate machining of internal holes of varying diameters. Furthermore, the linear scale allows for intuitive reading of the tool's current position, ensuring machining accuracy.

[0032] In general, this embodiment simplifies the adjustment mechanism, removes the adjustment bolts and circumferential size scales, making the structure simpler, while also maintaining the adjustment function, making it convenient for users to adjust the tool position according to actual conditions. Compared with the stepless adjustment in Example 1, this embodiment uses step-by-step size adjustment, which is suitable for use on products with fixed size designs.
