Detailed ways

The present invention will be further elaborated and illustrated below in conjunction with specific embodiments and description drawings:

Example 1

Please refer to Figures 1 and 2. A multifunctional CNC machine tool tool includes a tool head 10 and a tool handle 20. One end of the tool handle 20 is provided with a number of slots 21 along the axis of the tool handle 20. The tool head 10 corresponds to the slots 21. A protrusion 11 is provided, and the protrusion 11 snaps into the slot 21, and the center of the cutter head 10 and the center of the tool handle 20 are fixedly connected through a fastener 30. The cutter head 10 is provided with a cutting edge 12 along the radial direction of the tool handle 20.

When in use, one end of the tool handle 20 is fixedly connected to the spindle of the CNC machine tool, and the tool head 10 is contacted with the workpiece for processing, and the tool head 10 and the tool handle 20 are fixedly connected through the fastener 30, so that the tool head 10 and the tool handle 20 are fixedly connected. The tool handle 20 can be disassembled to facilitate people to replace the tool head 10. At the same time, the tool head 10 and the tool handle 20 can be made of different materials. For example, the tool head 10 can be made of a higher strength material, and the tool handle 20 can be used. It is made of lower-cost materials to reduce costs. The cutter head 10 is engaged with the slot 21 structure of the tool handle 20 through the protrusion 11, and the cutter head 10 is limited by the protrusion 11 and the slot 21. , to prevent the cutter head 10 from rotating and slipping during use.

Example 2

Please refer to FIG. 3 . There are several cutting edges 12 , and the cutting edges 12 are arranged around the axis of the tool handle 20 . The intervals between the cutting edges 12 are the same. The number of cutting edges 12 can be increased according to different types of tools, and when the cutting edges 12 are arranged around the axis of the tool handle 20, the force on each cutting edge 12 can be balanced when the cutting edges 12 come into contact with the workpiece.

The interior of the tool handle 20 is a hollow structure, and the end of the tool handle 20 away from the tool head 10 is provided with an opening. The tool handle 20 is provided with a liquid outlet hole 22 on the side close to the tool head 10. The liquid outlet hole 22 is provided corresponding to the cutting edge 12. Since the tool handle 20 is When the head 10 is in contact with the workpiece for processing, heat will be generated due to friction, which requires the processing part to be cooled during the processing. Therefore, it can be fixedly installed with the CNC machine tool through the hollow structure inside the tool holder 20 Afterwards, the coolant can be introduced into the tool holder 20 and ejected from the outlet hole 22 during subsequent machining, and corresponding cooling is carried out corresponding to the contact area between the cutting edge 12 and the workpiece, thereby improving the cooling effect.

The cross section of the card slot 21 is an inverted ladder shape. The structure facilitates the alignment between the tool head 10 and the tool handle 20.

Grooves 23 are provided on both sides of the tool handle 20. The grooves 23 extend along the axial direction of the tool handle 20. Therefore, when the tool handle 20 is inserted into the device of the CNC machine tool, it can be limited by the grooves 23 to prevent the tool handle 20 from being in the field of view. Rotation occurs during the process, and the tool handle 20 is stepped as a whole, and the diameter of the end of the tool handle 20 close to the cutter head 10 is smaller than the diameter of the other end, and the inner wall of the end of the tool handle 20 away from the cutter head 10 is provided with threads, which pass through the inner wall. The thread can be threadedly connected with the spindle, and the diameter of the part of the tool holder 20 close to the tool head 10 is reduced, thereby ensuring the firmness of fixation and reducing the processing interference of the tool holder 20 on the workpiece.

The invention provides a multifunctional CNC machine tool tool. When used, one end of the tool handle is fixedly connected to the spindle of the CNC machine tool, the tool head part is contacted with the workpiece for processing, and the tool head and the tool handle are fixedly connected through fasteners. , so that the cutter head and the handle can be disassembled to facilitate people to replace the cutter head. At the same time, the cutter head and the handle can be made of different materials. For example, the cutter head can be made of higher strength materials, and the handle can be made of cost-effective materials. It is made of lower materials to reduce costs. The cutter head is engaged with the slot structure of the tool handle through the protrusion. The cutter head is limited by the protrusion and the slot to avoid the cutter head from appearing during use. The situation of rotational slippage.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art will understand that , the technical solution of the present invention may be modified or equivalently substituted without departing from the essence and scope of the technical solution of the present invention.
