Description

Car drill dual purpose tool

This creation is an innovative improvement of a tool, especially a tool that can perform drilling and can perform turning operations. It has the function of both drilling and turning.

Generally used drills and turning tools are one of the most commonly used tools, especially on CNC lathe machine tools. It is the most common machining tool. It is necessary to machine an inner hole (or a class-shaped inner hole) for the workpiece. For face turning and outer diameter turning, an inner hole must be drilled first by means of a drill bit, and the inner hole is further finely machined by an inner hole turning tool. Finally, the outer end surface and the outer diameter of the workpiece are processed by means of the outer diameter turning tool. Turning and completing the preliminary processing of the workpiece.

However, this traditional processing method has been carried out for many years, and the processing procedure that is taken for granted has been adopted by the processing industry. Therefore, a conventional machining program must use at least three cutting tools, and the cost of the tool cannot be reduced. In addition to the tool change, the tool cost and processing time that can be reduced are limited.

Conventional lathe machining, drilling of workpieces, machining of inner and outer diameters and machining of end faces must be done with at least three tools. The cost of the tool is relatively increased, plus the time taken for the tool change, no matter how advanced technology. With the machine tool, the tool change time that can be reduced is still limited. There is still room for improvement in this traditional machining program and machining tool.

The utility model relates to a dual-purpose cutter, wherein the end of the cutter bar is provided with a cutter seat, and the cutter seat is locked with a discarding blade. The discarding blade comprises a first cutting edge and is located at a corner of the blade seat. And a second cutting edge is located adjacent to the central axis of the tool, and the first cutting edge is parallel to the central axis of the tool as a first cutting edge, between the first cutting edge and the second cutting edge a second trimming edge, wherein the first cutting edge and the second cutting edge form a turning tool cutter having a turning and drilling function, and the second cutting edge is formed into a cutting edge of the end face cutting, such as the same end face turning tool.

The car-drilling dual-purpose tool of this creation can be drilled and turned once, and the combination of the first cutting edge and the second cutting edge can be used to drill the workpiece through the first hole and the second. The combination of trimmings forms an inner hole turning tool, and the inner hole of the workpiece is gradually drilled and formed, and at the same time, the inner hole is turned to guide the corner to complete the processing of the inner hole of the first class; finally, the turning of the end face and the outer diameter of the workpiece is performed. While the tool moves out of the inner hole of the workpiece, the lathe is reversed, and the second cutting edge performs turning processing on the end surface. At the first cutting edge, the tool changes to the axial movement as it is displaced to the outer diameter position of the workpiece. The outer diameter of the workpiece is turned by the first cutting edge until the appropriate depth is stopped, and the inner and outer diameters and the end surface are cut, and the drilling and turning operations are completed simultaneously without changing the tool.

The car-drilling dual-purpose tool 10 of the present invention comprises a tool holder 11 which is sleeved in a tool magazine of a working machine, such as a lathe, and a knife bar 12 is extended at the front end of the tool holder 11, The body of the shank 12 is provided with a chip-removing groove 121. The shank of the shank 12 is provided with a seat 13 for locking the discarding blade 20.

The disposable blade 20 includes a first cutting edge 21 located at a corner of the blade holder 13 and a second cutting edge 22 adjacent to the central axis of the tool. The first cutting edge 21 The first cutting edge 23 is disposed in parallel with the central axis of the tool, and a second cutting edge 24 is disposed between the first cutting edge 21 and the second cutting edge 22, wherein the first cutting edge 21 and the second cutting edge 24 are obtained. The utility model comprises a turning tool for turning and drilling synchronous cutting, which can be used for drilling and turning of the inner hole, the outer diameter or the end surface, the first cutting edge 21, the second cutting edge 22 and the second cutting edge 24 The drill cutting edge forming a drilling function can be applied as a drilling function, and the second cutting edge 22 can form a cutting edge of a face cutting, such as the same end turning tool.

Referring to Figures 3, 4 and 5, which are schematic views of the workpiece and the present drilling, the first cutting edge 21 is set to an arc angle having a radius of between about 0.2 mm and 0.6 mm. a slight difference t between the arc angle and the first trimming edge 23, the drop difference t being approximately Between 0.02 and 0.1, depending on the cutting conditions, the four corners of the discarding blade 20 are provided with a drop value t of the small gap value, so that the first cutting edge 21 and the second cutting edge 22 are cutting. The disposable blade 20 does not fully contact the workpiece 30, creating excessive resistance.

Referring to FIG. 1 , a distribution of the reverse L shape is formed between the second cutting edge 22 of the artificial discarding blade 20 and the first cutting edge 23, and the discarding blade 20 can be turned and used again, and each discarding type is used.
