Description

Machining center having automatic tool loader

The present invention relates to a line type machining center having an automatic tool mounting device. More specifically, the automatic mounting device can be used to mount a sharp and heavy tool in a magazine to increase work efficiency and to prevent operator injuries. A line type machining center having an automatic tool mounting apparatus that can be prevented.

A machine used for machining a metal or non-metal material to a shape and dimensions using appropriate tools, or for finer machining of a semi-finished material by various cutting or non-cutting methods is called a machine tool. Among the machine tools described above, a machine tool in which chips are generated in a machining process is called a cutting machine tool, and a non-cut machine tool in which chips are not generated in a machining process is called a metal machine. The above-mentioned cutting machine tools include a lathe, a milling machine, a machining center, a drilling machine, a boring machine, a grinding machine, a gear processing machine, and a special processing machine. The metal forming machine includes a mechanical press, Bending machines, stair machines, and drawing machines.

The automation and numerical control (NC) of the cutting machining field is also rapidly progressing owing to the tendency of the industry as a whole. In recent years, a multi-function machining center has emerged as a result of the combined numerical control (NC) of the machine tool which has been divided into a rotary type milling system and a rotary type machining system. It is rapidly expanding.

The above-mentioned machining center is an NC machine tool which automatically carries out several types of cutting machining in one machine, and usually has an automatic tool changing function and a function of automatically cutting and dividing more than two sides of the workpiece. The above-mentioned machining center can be divided into two types, one for machining the entire non-circulating part and the other for machining the rotating part, regardless of where the development of the machining center is located. The machining centers for non-rotating parts have various parts modified by machining NC milling machines or NC drilling machines. Automatic tool changer (ATC), bullet magazine, automatic A machining center was created by combining an automatic loader (AL). Machining centers for rotating parts are used for various machining operations such as angle division, grooving, hole machining, tapping, etc. after turning the rotating parts with the NC lathe as the power generation base. In addition to the automatic tool changer (ATC) (AL), and the workpiece is held by a separately prepared chuck during processing, and the processed workpiece is released from the chuck, thereby automating the detachment of the workpiece.

The automatic tool changer (ATC) has at least 60 tools required for each process in the tool magazine device, and is configured to automatically exchange and supply appropriate tools necessary for various operations by a program. Machining centers with an automatic tool changer (ATC) located on top of a machine tool are called line machining centers.

Then, this process is repeated to mount all the tools in the magazine.

However, in the conventional line type machining center as described above, in order to mount the tool in the magazine, the operator must manually mount a sharp and heavy tool on the spindle, which not only reduces work efficiency but also may injure the operator. there is a problem.

An object of the present invention is to solve the conventional problems as described above, by mounting a sharp and heavy tool in the magazine using the automatic mounting device can not only increase the work efficiency, but also prevent workers from being injured, To provide a line type machining center with an automatic tool mounting apparatus.

As a means for achieving the above object, the configuration of the present invention, the machine main body, a mounting apparatus for moving the tool to the main shaft moving area which is provided at one end of the machine body, the main shaft can hold the tool, and A magazine which is installed in the machine body and which rotates the tool and cuts the workpiece, a magazine which is installed in the upper part of the machine body and stores a tool for exchanging the tool of the spindle when necessary, and a lower part of the magazine. It is preferable to include an ATC twin arm installed in the main shaft to transfer the tool of the main shaft to the standby port of the magazine.

According to one aspect of the present invention, the mounting apparatus includes a hydraulic cylinder for generating a driving force, an arm connected to the hydraulic cylinder around a rotating shaft, a finger connected to the arm, and the arm; It is preferable to include a spring provided between the fingers and a tool ID sensor for reading the tool information from the identification chip embedded in the tool.

In the configuration of the present invention, it is preferable that the above-described finger is formed in a semicircular shape so that the tool can be mounted.

In the configuration of the present invention, it is preferable that the above-described finger is formed in a semicircular shape so that the tool can be mounted.

The configuration of the present invention is preferable if the arm is rotated about the rotation axis to move the tool to the main axis moving region where the main axis can hold the tool.

This invention has the effect of not only improving work efficiency but also preventing an operator from being injured by mounting a sharp and heavy tool in a magazine using an automatic mounting apparatus.
