Description

Sensing device for the broken tool of automatic tool changer

The present invention relates to a tool breakage detection device for an automatic tool changer. More specifically, the tool breakage detection device is installed around a twin arm instead of a separate table, thereby ensuring the maximum processing area. It relates to a tool breakage detection device for an automatic tool changer, which can reduce the manufacturing cost by operating a tool breakage detection device using.

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. The above-mentioned machine tool is called a cutting machine tool in which a chip is generated in a machining process, and a non-cut machine tool in which a chip is not generated in a machining process is called a metal forming 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 above-mentioned machining center is a kind of cutting machine tool that automatically processes workpieces that require various tasks in lathes, mills, drilling machines, boring machines, and automatic tool changers for automatically exchanging columns and tools. Tool Changer (ATC), spindle head for transmitting rotational motion to the workpiece or tool, table for placing the workpiece, coolant pump for pumping coolant, coolant tank for storing coolant, and providing support It includes a bed, a leveling bolt for adjusting the height of the bed, birds installed on the bed, a splash guard, a casting table for controlling the overall operation, an NC device for numerical control, and the like.

The automatic tool changer (ATC) moves the spindle to a tool breakage detection device installed in a separate table with the tool mounted on the spindle to check whether the tool to be used is damaged after replacing the tool. It is to detect whether or not. The reason for detecting the damage of the tool as described above is that if the workpiece is processed while the tool is broken, the workpiece is not processed properly or the workpiece is damaged.

However, the conventional tool breakage detection device for an automatic tool changer as described above has a problem in that the processing area is relatively narrowed because the tool breakage detection device is provided in a separate table.

In addition, in the conventional tool breakage detection device for an automatic tool changer, since a tool breakage detection device is installed in a separate table, there is a problem in that manufacturing cost is relatively high by requiring a dedicated motor.

An object of the present invention is to solve the conventional problems as described above, the tool breakage detection device is installed around the twin arm instead of a separate table, which can ensure the maximum processing area, tool breakage for automatic tool changer It is to provide a detection device.

Another object of the present invention is to provide a tool breakage detection device for an automatic tool changer, which can reduce manufacturing costs by operating a tool breakage detection device using a twin arm drive motor.

As a means for achieving the above object, the configuration of the present invention, the drive motor is provided on one side of the ATC body, the tool port for holding the tool is provided on one side of the ATC body, and driven by the drive motor described above And a twin arm for replacing the tool by rotating and transporting the tool mounted in the tool port, the pinion gear rotated by the drive motor, and the pinion gear, and the end portion extends to the front of the tool port. It is preferable to include a rack support and a sensor provided at the end of the rack support.

In the configuration of the present invention, it is preferable that the end of the rack support is bent in a L shape.

It is preferable that the sensor of the present invention detects whether or not the tool is broken by measuring the length of the tool attached to the tool port.

According to the present invention, since the tool breakage detection device is installed around the twin arm instead of a separate table, the processing area can be secured as much as possible, and the manufacturing cost can be reduced by operating the tool breakage detection device using the twin arm driving motor. Which has the effect.

1 is a cross-sectional view illustrating an installation of an exhaust device for a CNC lathe according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention. Other objects, features, and operational advantages, including the purpose, operation, and effect of the present invention will become more apparent from the description of the preferred embodiments.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory only and are not to be construed as limiting the scope of the invention as disclosed in the accompanying claims. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and similarities, many of which are within the scope of the present invention. In addition, the terms or words used in the specification and claims herein should not be construed as being limited to the ordinary or dictionary meanings, and the inventors should properly explain the concept of terms in order to best explain their invention in the best way. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

1 is a cross-sectional view showing the installation of a tool breakage detection apparatus for an automatic tool changer according to an embodiment of the present invention.

As shown in Figure 1, the configuration of the tool breakage detection device for an automatic tool changer according to an embodiment of the present invention, the drive motor 2 is provided on one side of the ATC body 1, and the ATC body ( Tool port 6 installed on one side of 1) to hold a tool (not shown), and driven by the drive motor 2 described above and mounted on the tool port 6 (not shown) The twin arm 7 which replaces a tool by rotating conveyance, the pinion gear 3 rotated by the said drive motor 2, and the pinion gear 3 mentioned above, and the tip are connected to a tool port ( It comprises a rack support (4) extending to the front of 6) and the sensor (5) provided at the end of the rack support (4).

The end of the rack support (4) is made of a structure that is bent in the form of a letter.

The sensor 5 is configured to detect whether the tool is broken by measuring the length of the tool mounted on the tool port 6.

By the above configuration, the action of the tool breakage detection device for an automatic tool changer according to an embodiment of the present invention is as follows.

After the tool is mounted in the tool port 6 to change the tool, before the tool port 6 is rotated so that the twin arm 7 can take the tool mounted in the tool port 6, The tool mounted on the tool port 6 is checked for damage.

In this case, the pinion gear 3 is rotated by the rotational power of the drive motor 2, and the rack support 4 changes the rotational movement of the pinion gear 3 to linear movement. As the rack support 4 is linearly moved, the sensor 5 installed at the end of the rack support 4 moves around the tool port 6, and the tool port 6 is moved to the tool port 6. By measuring the length of the mounted tool it is detected whether the tool is broken. In this way, the tool breakage detection device is installed around the twin arm 7 instead of a separate table, thereby ensuring the maximum processing area, and using the drive motor 2 for the operation of the twin arm 7, the sensor ( By moving 5), manufacturing costs can be reduced.
