Description

CNC shank structure

The present invention relates to a tool bar structure applied to a CNC machine tool, in particular to a tool bar structure that can be simultaneously applied to side machining and end face machining.

1 is a cross-sectional view of a conventional shank structure mounted on a spindle structure. The conventional shank structure 14 is a single use when combined with a tool, and can only be used in combination with a side machining tool or a face machining tool. When processing, it is necessary to frequently change the tool, which reduces the processing speed and makes the productivity not greatly improved. It is based on how to design a arbor structure that can simultaneously install side machining and end machining tools.

The purpose of the new CNC cutter bar design is to improve the structure of the traditional cutter bar so that it can be firmly combined with the side cutter or the end cutter at the same time, so that it is not necessary to replace the cutter when performing side machining or end face machining, so as to effectively Improve the efficiency of processing.

The CNC cutter bar of the present invention extends downward from the shank, and the bottom end of the structure comprises a locking external tooth with different inner and outer diameters, a lower locking external tooth, a cone inside the collet and a corresponding upper and lower teeth. Nuts. The side milling locking portion is used for clamping and pressing the side machining tool by the combination of the upper screw and the upper locking outer tooth.

The inner end of the collet clamps the end face and the side machining tool, and the lower nut is pressed tightly. Various collets secure the tool.

The technical feature of the new CNC cutter bar is that the upper and lower outer teeth and the nut are tightened by the cutter bar, and the side machining tool and the end face machining tool can be used at the same time, and the operation of the tool change can be omitted during the machining operation. And improve the efficiency of processing.

Figure 4 is a schematic perspective view of the arbor structure of the present case

Referring to Fig. 2 is an exploded plan view of the new arbor structure of the present invention. The shank 1 can be clamped with various types of main shafts, and the mounting method is the same as that of the conventional structure. Referring to Fig. 1, no further details are provided herein. The following part of vv is a new innovation, which is characterized in that the bottom edge of the side milling lock 2 is provided with a locking outer tooth 3, and after clamping the side machining tool, the tool can be tightened by the upper locking nut 6 . The lower edge of the upper locking outer tooth 3 is internally provided with a lower locking outer tooth 4, and the side milling locking portion 2 is at the center of the bottom surface and is provided with a cone inner portion 5 of the collet. The inner cone portion 5 of the collet is used for clamping the end surface and the side machining tool, and the lower locking nut 7 is pressed by the lower locking nut 7 to fix the cutter. FIG. 2 is a schematic view of the creation combination, FIG. 3 Then it is a combined perspective view.

In summary, with the improvement of the creation, the CNC tool holder can combine the machining tools of the side surface and the end surface at the same time, and the machining work of the side surface and the end surface does not need to change the tool, but Improve the efficiency of processing.

The above is only the preferred embodiment of the present invention, and it is not possible to limit the scope of the implementation of this case. The simple equivalent changes or modifications made in the scope of patent application and the contents of the patent specification in this case are still patents in this case. Coverage.
