Description

Technical Field

[0001] The utility model relates to the field of mechanical processing tools, in particular to a composite tool for machine tools. Background Art

[0002] At present, for CNC machine tools, it generally takes several seconds to change the tool, and the tool also needs time to move during processing. Milling cutters or reaming cutters are needed to process steps and countersunk heads, and if chamfering is required, a chamfering cutter is also needed to remove the flash of the hole.

[0003] In normal CNC machining operations, we often need two or three tools to complete the machining of a countersunk cone surface. The operation is cumbersome, time-consuming, labor-intensive, and the machining efficiency is low. Utility Model Content

[0004] The purpose of the utility model is to provide a composite tool for machine tools to solve the above problems.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model discloses a composite tool for a machine tool, comprising a tool rod and a connecting rod connected to each other, wherein the tool rod is designed in a stepped shape from left to right, and four slots of different lengths are provided on the outer surface of the tool rod, and mounting pieces with lengths matching the lengths of the respective slots are slidably connected in the slots, and the mounting pieces are fixed in the slots, and each of the mounting pieces is provided with a tooth groove, and different tool teeth matching the stepped layers of the tool rod are installed in different tooth grooves.

[0007] Furthermore, a slide rail is provided at the bottom of the slot, a slide hole is provided at the bottom of the mounting piece, and the mounting piece is slidably connected to the slide rail through the slide hole.

[0008] Furthermore, the mounting piece is fixed to the knife rod by screws.

[0009] Furthermore, the blade teeth are fixed to the mounting member by screws.

[0010] Furthermore, cooling holes are provided on the tool rod and the connecting rod, and the cooling holes correspond to the mounting parts.

[0011] Compared with the prior art, the beneficial technical effects of the utility model are:

[0012] The utility model is simple and practical, can be applied to various occasions where countersinking and chamfering are required after drilling, integrates processes such as hole reaming, taper, and countersinking, and combines multiple tool functions into one tool, saving the time for tool changing and machine tool movement, saving processing time of about 10 minutes per piece, greatly improving production efficiency, and can improve the position accuracy of the hole.
