Technical Field

[0001] This utility model relates to the field of lathe tool technology, and in particular to a lathe tool structure with adjustable center height. Background Technology

[0002] In the field of machining, the lathe tool is a key tool used for metal cutting on a lathe. Traditional lathe tools typically have a fixed center height, meaning that once fixed, the cutting position relative to the workpiece axis remains constant. However, in actual machining processes, different machining requirements and workpiece shapes often necessitate that the lathe tool adapt to different cutting angles.

[0003] For example, when machining parts with complex shapes, such as stepped shafts and tapered shafts, a cutting tool with a fixed center height often cannot meet the machining requirements. It is necessary to clamp the workpiece or adjust the spindle, especially when fine-tuning small dimensions, which brings inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a lathe tool structure with adjustable center height, which can increase the height of the tool head on the tool holder, thereby changing the machining center height of the lathe tool and achieving fine adjustment and alignment.

[0017] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figures 1 to 3 An adjustable center height turning tool structure includes a tool holder 10, a tool head 20, and a cutting blade 30. One end of the tool holder 10 is provided with a guide groove 11 in the radial direction. The tool head 20 is slidably disposed in the guide groove 11, and an adjusting member 40 is provided on one side of the guide groove 11. The upper end of the adjusting member 40 is rotatably connected to the tool holder 10, and the lower end of the adjusting member 40 is threadedly connected to the tool head 20. The adjusting member 40 drives the tool head 20 to slide along the guide groove 11, and the tool holder 10 and the tool head 20 are fixedly connected by bolts 12. The cutting blade 30 is disposed at the end of the tool head 20 away from the tool holder 10.

[0018] The cutting tool 30 is fixed to one end of the cutting head 20. The cutting head 20 is slidably inserted into one end of the tool holder 10 through the guide groove 11. The upper end of the adjusting member 40 is rotatably connected to the tool holder 10, and the lower end is threadedly connected to the cutting head 20. By rotating the adjusting member 40, the cutting head 20 is restricted by the guide groove 11 and can only slide up and down, thereby changing the machining center height of the cutting tool and achieving fine adjustment and alignment. The adjusted cutting head 20 is then fixed by the bolt 12, which facilitates subsequent machining. Different cutting heads 20 can also be replaced to adapt to different machining processes.

[0019] The tool holder 10 has a U-shaped opening 13 at one end, and a guide groove 11 is vertically set in the opening 13. The inner wall of the opening 13 is provided with a sliding groove 14 along the axial direction, and the upper end of the adjusting member 40 is slidably inserted into the sliding groove 14.

[0020] The adjusting component 40 includes a knob 41 and a screw 42. The knob 41 is rotatably disposed in the slide groove 14. The screw 42 is fixed to the lower end of the knob 41 and extends into the opening 13. The lower end of the cutter head 20 near the end of the cutter handle 10 is provided with a threaded hole 21, which is threadedly connected to the screw 42.

[0021] The slide groove 14 and the guide groove 11 are arranged perpendicularly to each other. Therefore, during assembly, the adjusting member 40 is first inserted into the tool holder 10 along the slide groove 14, and then the tool head 20 is inserted into the opening 13 from the lower end of the tool holder 10 along the guide groove 11. The threaded hole 21 is aligned with the screw 42. The tool holder 10 can be smoothly inserted by turning the knob 41, which achieves the purpose of mutual restriction. That is, the adjusting member 40 is restricted by the tool head 20 to prevent it from sliding out of the slide groove 14, and the tool head 20 is prevented from sliding out of the guide groove 11 by the threaded connection of the adjusting member 40, thus achieving the two effects of installation and adjustment.

[0022] Furthermore, the knob 41 has an I-shaped structure. The lower end of the knob 41 is locked in the slide groove 14, and the upper end of the knob 41 extends out of the surface of the handle 10. The upper end of the knob 41 is provided with a scale and an internal hexagonal hole. The angle of rotation of the knob 41 can be converted to correspond to the height of the knife head 20 rising or falling, so that people can more intuitively understand the height of adjustment. At the same time, the internal hexagonal hole also makes it convenient for people to use an internal hexagonal wrench to rotate it.

[0023] A spring 43 is provided between the lower end of the knob 41 and the threaded hole 21. The spring 43 is sleeved on the surface of the screw 42. The spring 43 can apply a downward force to the cutter head 20, thereby playing a role in processing vibration reduction. At the same time, there is a thread gap in the threaded connection between the screw 42 and the threaded hole 21. Therefore, the force of the spring 43 makes the screw 42 fit tightly against the threaded hole 21.

[0024] In the above scheme, the handle 10 has through holes 15 on both sides of the opening 13, and the cutter head 20 has a waist-shaped hole 22 corresponding to the through holes 15. The bolt 12 passes through the through holes 15 and the waist-shaped hole 22 to fix the cutter head 20. When the height of the cutter head 20 is adjusted, the waist-shaped hole 22 can prevent the bolt 12 from restricting the movement of the cutter head 20, ensuring smooth adjustment. After the adjustment is completed, the bolt 12 is tightened to clamp the cutter head 20 on both sides of the opening 13, thereby reducing the gap between the cutter head 20 and the inner wall of the opening 13 and improving the connection stability.

[0025] The guide groove 11 has a serrated structure, and the two sides of the cutter head 20 are provided with corresponding protrusions 23. The protrusions 23 improve the connection strength between the cutter head 20 and the handle 10, and also play a better sliding guiding role.

[0026] A mounting groove 24 is provided at the end of the cutter head 20 away from the tool holder 10. The blade 30 is detachably connected and installed in the mounting groove 24. People can remove the blade 30 and replace it with different types of blades 30 to meet different processing needs.

[0027] This utility model provides a lathe tool structure with adjustable center height. The cutting tool is fixed to one end of the tool head, which is slidably inserted into one end of the tool holder through a guide groove. The upper end of the tool head is rotatably connected to the tool holder, and the lower end is threadedly connected to the tool head. By rotating the adjustment component, the tool head is restricted by the guide groove and can only slide up and down, thereby changing the machining center height of the lathe tool to achieve fine adjustment and alignment. The adjusted tool head is then fixed with bolts, which facilitates subsequent machining. Furthermore, different tool heads can be replaced to adapt to different machining processes.

[0028] 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.
