Description

[0001] The present invention relates to a rotary milling tool arrangement,

According to the present invention, a tool having various dimensions for cutting a workpiece in a milling machine is arranged and aligned so that an operator can select an appropriate tool as needed to prevent damage or breakage of the tool, And more particularly, to a rotary milling tool trimmer for improving working efficiency according to the present invention.

A milling machine is a machine tool that cuts a workpiece into a plane, a curved surface, a groove or the like using a tool such as a milling cutter or an end mill. The milling machine has a knee type and a bed type.

The above-mentioned milling machine has a tool such as a milling cutter for machining a workpiece, which is coupled to the spindle head assembly, and a workpiece to be machined is fixed on the upper surface of the transfer table of the milling machine.

The control unit of the milling machine inputs the set values and manipulates the various handles to place the workpiece in the machining position.

Then, when the operation switch of the milling machine is turned ON, the tool coupled to the spindle head assembly is rotated, and at the same time, the transfer table is moved in the front, back, The workpiece is cut and processed by the cutting edge portion of the rotating tool in contact with the workpiece.

In general, tools such as drills and end mills are manufactured in various sizes depending on the application, and an appropriate tool is selected and used at the time of operation. Therefore, a stand for a tool is placed on one side of a milling machine, a drilling machine, a lathe, etc., and tools of various sizes are arranged and aligned on the stand, and an operator selects and uses an appropriate tool as needed.

However, such a conventional stand for a tool is structured such that a plurality of insertion holes, which are formed in the same plane on the upper surface, are uniformly formed so that the user can insert and set a tool of various sizes into any insertion hole. Therefore, the positions where the tools are fixed are different from each other according to the habit of the operator. In addition, there is a problem in that the size of the insert hole is inconsistent with the size of the tool, so that the tool can not be stably set, and it is inconvenient to insert or fix the tool by inserting it into the insert hole.

Although these machine tools have achieved considerable commercial success, in all cases the unproductive time taken to exchange one tool for another becomes an important factor limiting production.

It is highly desirable that the automatic exchange of tools be carried out in as short a time as possible. In machining operations where several different machining operations have to be performed with several different cutting tools, adding up the time taken to exchange the cutting tool between individual machining operations can result in a significant amount of unproductive time.

Korean Utility Model Application Publication No. 1999-0035364 discloses a stand having a variety of insertion holes formed therein for pulling out a tool necessary for machining a workpiece by inserting various tools into the stand for the tool and rotating the stand on the bottom of the stand A stand for a tool mounted on a separate support is disclosed,
