Description

Technical Field

[0001] This utility model relates to the field of knurling tool technology, and in particular to a single-wheel knurling tool. Background Technology

[0002] Knurling is a machining process that involves rolling straight or knurled patterns onto the circumferential surface of shaft-like workpieces. After knurling, the surface acquires oblique grooves and a knurled structure, thereby increasing friction and improving aesthetics. Existing knurling tools typically consist of a tool holder and a knurling wheel for creating the knurling pattern. The knurling wheel is rotatably mounted on the tool holder via bearings, and the tool holder is then fixed to a machining lathe. The surface is knurled by rolling.

[0003] Existing knurling tools, once fixed, require adjustment when necessary. This is suitable for situations with large dimensional deviations requiring significant adjustments, but for minor dimensional calibrations, the knurling tool cannot be directly disassembled and adjusted. Instead, fine adjustments must be made using the clamping parts on the workpiece and the knurling tool, which is inconvenient and prevents quick adjustments. Utility Model Content

[0004] The purpose of this invention is to provide a single-wheel knurling tool that allows for fine adjustment of small dimensions by adjusting the height between the knurling wheel and the tool holder.

[0005] The technical solution adopted by the single-wheel knurling tool disclosed in this utility model is: A single-wheel knurling tool includes a tool holder, a tool head, and a knurling wheel. The tool head is fixedly connected to the tool holder by fasteners. The knurling wheel is rotatably disposed on one side of the tool head, with one side of the knurling wheel protruding from the tool head. A mounting groove is provided at one end of the tool holder. A retaining strip is provided near the tool holder on the tool head. The retaining strip is disposed in the mounting groove, and a gap is provided between the retaining strip and the inner wall of the mounting groove. Adjustment holes are provided on the upper and lower surfaces of the tool holder corresponding to the mounting groove. An adjustment screw is provided inside the adjustment hole, and one end of the adjustment screw extends into the mounting groove and abuts against the surface of the retaining strip.

[0006] As a preferred embodiment, one side of the cutter head has an inclined structure, and the inclined surface has a groove. A stepped shaft is provided in the groove, and one end of the stepped shaft protrudes from the groove. The knurling wheel is sleeved on one end of the stepped shaft, and the knurling wheel is rotatably connected to the stepped shaft. A cover plate is provided on the surface of the knurling wheel, and the cover plate, the stepped shaft, and the knurling wheel are fixed to one side of the cutter head by fixing screws.

[0007] As a preferred embodiment, the handle has an L-shaped structure, and the thickness of the short side of the handle is greater than that of the long side of the handle. The blade tip is fixedly connected to the short side of the handle by a fastening screw.

[0008] As a preferred embodiment, the fastening screw passes through the retaining strip, dividing the retaining strip into two sections, and one end of the fastening screw is threadedly connected to the tool holder.

[0009] As a preferred embodiment, there are four adjustment holes, which are located on the upper and lower surfaces of the two clips respectively. The number of adjustment screws corresponds to the number of adjustment holes, and the adjustment holes on the upper and lower surfaces of the tool holder are positioned opposite each other.

[0010] The beneficial effects of the single-wheel knurling tool disclosed in this utility model are as follows: During installation and use, the knurling wheel is first fixed to the tool head, then the tool head is fixed to the tool holder, and then the other end of the tool holder is fixedly connected to the spindle of the lathe. Finally, the knurling wheel and the workpiece are aligned and calibrated. When the tool head is fixed to the tool holder, the retaining strip is first inserted into the mounting groove of the tool holder, and then the length of one end extending into the mounting groove is adjusted by turning the adjusting screw inside the corresponding adjusting hole. This allows the retaining strip to be pushed downwards or upwards, thereby adjusting the vertical height of the retaining strip in the mounting groove, and simultaneously driving the height of the knurling wheel on the tool head. This achieves fine adjustment of small dimensions and avoids the need to disassemble the tool holder or adjust the spindle, thus avoiding inconvenience. Attached Figure Description

[0012] Figure 2 This is an exploded view of a single-wheel knurling tool according to this utility model. Detailed Implementation

[0013] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2 A single-wheel knurling tool includes a tool holder 10, a tool head 20, and a knurling wheel 30. The tool head 20 is fixedly connected to the tool holder 10 by fasteners. The knurling wheel 30 is rotatably disposed on one side of the tool head 20, with one side of the knurling wheel 30 protruding from the tool head 20. One end of the tool holder 10 has a mounting groove 11. The tool head 20 has a retaining strip 21 near the tool holder 10. The retaining strip 21 is disposed in the mounting groove 11, and there is a gap between the retaining strip 21 and the inner wall of the mounting groove 11. The tool holder 10 has adjustment holes 12 on both the upper and lower surfaces corresponding to the mounting groove 11. An adjustment screw 13 is disposed inside the adjustment hole 12. One end of the adjustment screw 13 extends into the mounting groove 11 and abuts against the surface of the retaining strip 21.

[0014] During installation and use, first fix the knurling wheel 30 onto the cutter head 20, then fix the cutter head 20 onto the tool holder 10, and then fix the other end of the tool holder 10 to the lathe spindle. Finally, calibrate and align the knurling wheel 30 with the workpiece. When fixing the cutter head 20 to the tool holder 10, first insert the retaining strip 21 into the mounting groove 11 of the tool holder 10, and then adjust the length of one end extending into the mounting groove 11 by turning the adjusting screw 13 inside the corresponding adjusting hole 12. This will push the retaining strip 21 downwards or upwards, thereby adjusting the vertical height of the retaining strip 21 in the mounting groove 11, and simultaneously driving the height of the knurling wheel 30 on the cutter head 20. This allows for fine adjustments of small dimensions and avoids the need to disassemble the tool holder 10 or adjust the spindle, thus avoiding inconvenience.

[0015] In the above scheme, one side of the cutter head 20 has a bevel structure, and a groove 22 is provided on the bevel. A stepped shaft 23 is provided in the groove 22. One end of the stepped shaft 23 protrudes from the groove 22. A knurling wheel 30 is sleeved on one end of the stepped shaft 23, and the knurling wheel 30 is rotatably connected to the stepped shaft 23. A cover plate 24 is provided on the surface of the knurling wheel 30. The cover plate 24, the stepped shaft 23 and the knurling wheel 30 are fixed to one side of the cutter head 20 by fixing screws 25.

[0016] The knurling wheel 30 is fixed in the stepped shaft 23 by the cooperation of the cover plate 24 and the fixing screw 25. At the same time, the knurling wheel 30 with different pattern structures can be adjusted according to different processing requirements. The stepped shaft 23 ensures that the knurling wheel 30 can rotate while being fixed in the cutter head 20. One side of the cutter head 20 has a beveled structure, and the corresponding knurling wheel 30 is set at an angle, so that the pattern it cuts also has an angled structure, which improves friction and other effects.

[0017] The handle 10 has an L-shaped structure, and the thickness of the short side of the handle 10 is greater than that of the long side, which increases the contact area between the handle 10 and the cutter head 20, improves the stability of the connection, and provides space for the installation design of the retaining strip 21 and the mounting groove 11. The cutter head 20 is fixedly connected to the short side of the handle 10 by fastening screws. When the cutter head 20 needs to be replaced, it can be directly removed and replaced, which is more convenient and quick.

[0018] The fastening screw passes through the retaining strip 21, dividing the retaining strip 21 into two sections. One end of the fastening screw is threadedly connected to the tool holder 10. There are four adjustment holes 12, which are located on the upper and lower surfaces of the two sections of the retaining strip 21 respectively. The number of adjustment screws 13 corresponds to the number of adjustment holes 12, and the positions of the adjustment holes 12 on the upper and lower surfaces of the tool holder 10 are set opposite to each other.

[0019] By dividing the clip 21 into two sections and providing corresponding adjustment holes 12 and adjustment screws 13, the two sections of the clip 21 can be adjusted accordingly. When the fastening screws at the bottom of both sections of the clip 21 extend out of the mounting groove 11, the cutter head 20 is raised. Conversely, when the fastening screws at the top of both sections of the clip 21 extend out of the mounting groove 11, the cutter head 20 is lowered, thus achieving a fine adjustment in height. Furthermore, when the two fastening screws at the top or bottom extend to different heights, a fine adjustment in angle can be made.

[0020] This utility model provides a single-wheel knurling tool. During installation and use, the knurling wheel 30 is first fixed to the tool head 20, then the tool head 20 is fixed to the tool holder 10. The other end of the tool holder 10 is then fixedly connected to the lathe spindle. Finally, the knurling wheel 30 is aligned with the workpiece. When the tool head 20 is fixed to the tool holder 10, the retaining strip 21 is first inserted into the mounting groove 11 of the tool holder 10. Then, by turning the adjusting screw 13 inside the corresponding adjusting hole 12, the length of one end extending into the mounting groove 11 is adjusted, thereby pushing the retaining strip 21 downwards or upwards, thus adjusting the vertical height of the retaining strip 21 within the mounting groove 11. This simultaneously drives the height of the knurling wheel 30 on the tool head 20, achieving fine adjustments in small dimensions. This also avoids the need to disassemble the tool holder 10 or adjust the spindle, preventing inconvenience.

[0021] 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 the scope of protection of this utility model. 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 essence and scope of the technical solutions of this utility model.
