Description
The present invention relates to a tool magazine of a machine tool, and more particularly, to a tool transport apparatus of a machine tool tool magazine for moving a tool to a tool changer in a tool magazine for storing a plurality of tools in a matrix form.
In general, a machine tool such as a machining center performs a variety of machining in one process by using a plurality of tools alternately, and has a tool magazine for storing a plurality of tools to shorten a tool change time.
The tool housed in the tool magazine is transferred to the tool changer by the tool transfer device, and the tool changer exchanges the tool mounted on the main shaft with the tool supplied from the tool magazine.
However, when the tool is mounted on the tool storage unit of the tool magazine, the axial direction of the tool to be mounted is different from the axial direction of the tool mounted on the main shaft, that is, the phase of the tool mounted on the tool storage unit of the tool is mounted on the main shaft. It may be different from the phase. For example, a large diameter tool having an asymmetrical shape or a large rotation radius of the tool may not be easily accommodated in the tool magazine or may interfere with other mechanical structures, so that the tool may be rotated at a right angle and accommodated.
Accordingly, the tool housing and the main shaft of the tool magazine are provided with a key block for inducing the tool to be seated in a predetermined phase, and a key groove is formed in the tool to accommodate the key block.
An example of a tool carrier, which is one of the devices for rotating a phase by rotating a conventional tool, is disclosed in Patent Application No. 10-2010-0101179 (name: Tool Carrier of Automatic Tool Changer, Prior Document 1) filed by the applicant of the present invention. It is.
However, as disclosed in the prior art, the tool carrier uses a cam to change the phase of the tool, and the cam blocks 200 and 300 corresponding to the cam track and the pins corresponding to the cam follow to implement the cam structure. In addition to having a 54), a pocket unit 50 for rotating the tool has to be provided, such that the structure is complicated and the design of the cam track has to be designed to match the phase.
On the other hand, the tool magazine is a matrix-type tool magazine (Matrix-type tool magazine) for receiving a plurality of tools in the form of a matrix, as an example of such a matrix tool magazine (Patent Document 2) (Patent Document 2). In the following, a plurality of tool holders having a plurality of tool accommodation portions are disclosed. The conventional tool holder is formed in a plate shape has a problem that is easily deformed by the load and external force of the tool.
The present invention was created to improve the problems of the tool transfer device of the conventional machine tool tool magazine as described above, the tool for transferring the tool from the standby port to the tool change unit by rotating the tool in advance in accordance with the insertion direction of the main shaft It is an object of the present invention to provide a tool conveying device of a machine tool tool magazine which can remove a component that rotates a tool from a carrier device, thereby simplifying the structure of the device.
In addition, another object of the present invention is to provide a tool transport apparatus of a machine tool tool magazine capable of firmly supporting a tool holder for accommodating a tool and preventing the tool holder from being deformed by a load or an external force of the tool.
In order to achieve the above object, the tool transport apparatus of a machine tool tool magazine according to the present invention includes a tool storage unit for storing a tool supplied to a main shaft of a machine tool, and a tool housed in the tool storage unit. A gripper for rotating the gripper, a rotating unit for axially rotating the gripper, a tool changing unit for exchanging a tool of the main shaft, a standby port for accommodating a tool supplied from the main shaft while receiving a tool supplied to the main shaft by the tool changing unit, A tool carrier for moving the standby port toward the tool change unit, a sub transport unit for taking a tool from the gripper, transferring the tool to the standby port, separating the tool from the standby port, and returning the tool; When moving toward the sub feed unit along (X axis direction) It is characterized in that it comprises a Y-axis transfer unit that moves the X axis feed unit, and the gripper towards the sub-transfer unit along the X-axis direction normal to the Y-axis direction of the tool receiving unit.
Preferably, the rotation unit includes a rotation support member for axially supporting the gripper, and a rotation actuator for forward and reverse rotation of the gripper in a predetermined angle range.
The sub conveying unit includes a sub changer that takes over and grips a tool from the gripper, an elevating unit for elevating the sub changer to a height of a standby port along a Y axis direction, and the sub changer with an X axis direction and a Y axis direction. And a Z-axis transfer unit that moves toward the standby port along the vertical Z-axis direction.
More preferably, the tool carrier includes a pivoting arm pivoting integrally with the standby port about a hinge axis parallel to the Y axis, and a pivoting unit for pivoting the pivoting arm.
As described above, according to the tool transport apparatus of the machine tool tool magazine according to the present invention, the tool is rotated in the tool carrier device which transfers the tool from the standby port to the tool change unit by rotating the tool in advance in accordance with the insertion direction of the main shaft. The component can be removed and thereby the structure of the device can be simply configured, and the tool holder can be firmly supported to prevent the tool holder from being deformed by the load of the tool.
