Abstract

PURPOSE:To provide possibility of increasing the number of tools accommodated even with a small-sized magazine, by arranging magazines to accommodate tools divided in small units outside the machine tool and by installing a relay pot to receive and hand over tools which travel between the units. CONSTITUTION:Magazines 1, 2 storing tools, which can be driven individually, are arranged outsie the machine tool divided in small units. A relay pot 5 to receive and hand over tools between the units is moved by a transport device 4 to stop at a position for receiving or handing over tools. This pot 5 turns 90 deg. at positions of small units and the position of replacement arm, A, to facilitate reception and handover of tools. Reception and handover of tools between the magazines 1, 2 for small units and the relay pot 5 is performed by a tool replacement device 12 while that between the relay pot 5 and spindle 11, by the replacement arm 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a machine tool including an automatic tool changer, such as a machining machine: J Kuseshita.

A machine tool with an automatic tool changer is equipped with a magazine that stores multiple tools. There is a limit to the number of tools.Furthermore, it is impossible for safety reasons to change the setup by replacing the tool stored in the magazine with another tool while the machine tool is operating. It's better to replace the unit itself: There is a y sector.

The device for replacing the pins becomes complicated and large-scale, which increases the manufacturing cost or the area occupied by the machine tool.

In view of the above-mentioned conventional problems, the present invention has a simple structure and facilitates increasing the number of tools stored.

In addition, the purpose is to provide a machine tool that allows the setup of tools in the magazine to be changed while the machine tool is in operation, allowing the tool mounted on the spindle to be replaced with the tool stored in the magazine. In a machine tool equipped with a means for A relay pot that can be positioned and stopped at a position where the tool holder is transferred between the magas and the cylindrical gears; be a sign. That is, the magazine 5 for storing tools is divided into small units and arranged outside the machine tool.
Each magazine allows one of the machine tools to be switched to manual operation even when the machine tool is in automatic operation, allowing safe tool setup changes without affecting automatic operation in any way. .

Embodiments according to the present invention will be described below based on the drawings.

FIG. 1 shows a plan view of the embodiment, and FIG. 2 shows a front view. In the figure, 1 is a /161 magazine: J, 2 is a /I62 magazine, and if necessary, a large number of magazines for storing tools such as 43 magazines or less are provided. Reference numeral 3 denotes a tool stored in each magazine and mounted on the main shaft 11 of the machine body 9. Reference numeral 4 denotes a conveyance device disposed on the side of each magazine, and a relay pot 5 to which a tool B can be attached is movably placed on the conveyance device. The relay pot 5 is positioned and stopped at each magnification position and the front end position (indicated by A in FIG. 1). In addition, this relay pot 5 has a front end value #A of 9.
Turn 0°.

The control panel for Magajishi is shown. Reference numeral 10 denotes an exchange arm that receives and transfers a new tool and an old tool to the main spindle 11. The exchange arm moves back and forth between the main @ position and the front end position A of the relay pot 5, and the tool receiver also transfers tools at the front end position A of the relay pot 5. 12 indicates that when the relay point 5 stops at each magazine position, the tools in the magazine and the relay pot 5
This is a tool exchange device that exchanges tools attached to the machine. 7

8, manual operation can be performed independently.

□ In a machine tool having the structure described above, when automatic operation under numerical control is performed, processing is performed using a tool attached to the main spindle 11. At that time, the tool change is 4
1 magazine: Select a predetermined tool 3 from Jl or scrap 2 magazine 2, and transfer it to relay point 5 by tool changer 12.
, and relay point 5 with the new tool has a front end value of 1 [A
Move to. At the front end position A, the exchange arm 10 receives and transfers new tools and old tools to and from the relay pot 5. The new tool is attached to the spindle 11 by the exchange arm 10.

Here, when changing the setup of the tools in /%2 magazine 2, switch only the 42 magazine J2 to manual operation and perform the tool change, that is, setup change, while rotating the magazine 2 manually. can be done. In addition, automatic operation by machine tools is performed using Fu1 Maga and ;Si1.

Tool setup changes can be performed without affecting the automatic operation of the machine.

As explained above, according to the present invention, a plurality of tool magazines are installed in parallel, and each can be manually operated independently, without interrupting the automatic operation of the machine tool. It is possible to change the setup of tools within the cage, and it is also possible to significantly increase the number of tools that can be stored.

In addition, you can set the number of tool magazines as you like,
The machine tool system can be expanded or contracted freely.
