Technical Field

[0001] The utility model belongs to the technical field of lathe tools, and relates to a turning and drilling dual-purpose machine-clamped turning tool and a lathe. Background Art

[0002] A lathe is a machine tool that primarily uses a turning tool to perform turning operations on rotating workpieces. Drills, reamers, reamers, taps, dies, and knurling tools can also be used on a lathe to perform corresponding workpiece processing. Currently, when using a lathe to process large quantities of a single workpiece, both cutting and center hole drilling are required. This requires frequent tool changes, tool table rotation, and tailstock adjustments, resulting in low processing efficiency. Alternatively, CNC machine tools can be used to improve processing efficiency through rapid and automatic tool changes. However, the cost of CNC machine tools is significantly higher than that of conventional lathes, requiring a high initial investment. Furthermore, using CNC machine tools to process large quantities of a single workpiece is not economical. Utility Model Content

[0031] Example:

[0032] like Figure 1 、 Figure 2 As shown, the turning and drilling dual-purpose machine-clamped turning tool of this embodiment includes a tool rod 1, a cutting bit (a support portion 21 and a carbide head 22), an adjusting sleeve 3, a drill body 4 and a fastening and adjusting member 5.

[0033] The tool rod 1 is a quasi-cuboid structure. The rear end of the tool rod 1 is used to be assembled on the tool clamping seat of the lathe, and the front end of the tool rod 1 is provided with a cutting head.

[0034] The cutting head includes a support portion 21 and a carbide head 22 . The support portion 21 is located at the front end of the shank 1 , and the carbide head 22 is assembled on the support portion 21 .

[0035] Specifically, the front end of the support portion 21 defines a retaining groove 211, and the carbide head 22 defines mounting holes along its upper and lower end surfaces. The mounting holes of the carbide head 22 are bolted to the support portion 21, positioning the carbide head 22 within the retaining groove 211. The retaining groove 211 and the bolts constrain the carbide head 22 in the X and Y axes. The support portion 21 is provided with a clip 212, which abuts the upper end surface of the carbide head 22 to constrain the carbide head 22 in the Z axis, thereby firmly clamping the carbide head 22. The rotating workpiece interacts with the carbide head 22 to perform a cutting operation on the workpiece.

[0036] An adjusting sleeve 3 is welded to one side of the shank 1, and four limiting holes 31 are provided on the side of the adjusting sleeve 3 along the axial direction; the drill body 4 passes through the adjusting sleeve 3, and the drill head of the drill body 4 can be exposed from the front end of the adjusting sleeve 3; the fastening adjusting piece 5 is connected to the limiting hole 31, and the fastening adjusting piece 5 can abut against the rod of the drill body 4, and the fastening adjusting piece 5 can also be separated from the rod of the drill body 4.

[0037] Specifically, the limiting hole 31 is configured as a threaded hole, and the lower end of the tightening and adjusting member 5 is provided with external threads, which are threadedly connected to the threaded hole. A tightening portion 51 is provided at the upper end of the tightening and adjusting member 5. External force acts on the tightening portion 51 to drive the tightening and adjusting member 5 to rotate in the forward or reverse direction. The tightening portion 51 is configured as a hexagonal socket. An operator rotates the tightening portion 51 via the hexagonal socket, driving the tightening and adjusting member 5 to rotate in the forward or reverse direction, thereby moving the tightening and adjusting member 5 relative to the limiting hole 31, causing the tightening and adjusting member 5 to abut or disengage from the rod portion of the drill bit body 4.

[0038] When drilling is required, the fastening adjustment part 5 is separated from the rod of the drill body 4, and the drill head of the drill body 4 is exposed longer from the front end of the adjusting sleeve 3 and located in front of the carbide head 22. The rotating workpiece interacts with the drill head of the drill body 4 to realize the drilling operation on the workpiece.

[0039] A lathe, which is preferably a common lathe, has a tool holder on which the turning and drilling dual-purpose machine-clamped turning tool of the embodiment is assembled.

[0040] So far, the present embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the turning and drilling dual-purpose machine clamp turning tool and lathe of the present invention. The turning and drilling dual-purpose machine clamp turning tool of the present invention is applied to a lathe, and the lathe can be an ordinary lathe. When using the lathe to process a large number of single-category workpieces, it is necessary to perform both cutting and center hole drilling on the workpiece. There is no need to frequently change the tool or rotate the tool table or adjust the tailstock operation, nor is there any need to use a CNC machine tool. After the cutting head completes the cutting operation on the workpiece, it is only necessary to expose the drill head of the drill body 4 from the front end of the adjusting sleeve 3 to a longer size and to be located in front of the cutting head, so that the drilling operation on the workpiece can be achieved.
