Description

  The present invention relates to, for example, a lathe, a milling machine, or a combined 5-axis machine having a turning function and a milling function (a turning center capable of simultaneous 5-axis control).

  Conventionally, lathes, milling machines, and even complex curved surfaces can be processed with high efficiency, and multiple processes such as vertical, horizontal, and slanted holes, threading, and milling can be performed with one chucking and with standard tools. Vertical compound 5-axis machines with turning and milling functions are used. Generally, in lathes and milling machines, horizontal cross rails are installed as horizontal guides on the column that stands up against the turning table. A tool mounting portion is provided on a tool post that is provided so as to be movable and is movable in the X-axis direction (left-right direction) along the cross rail, or is provided so as to be movable in the left-right direction and the up-down direction as described above. Alternatively, a ram having a spindle can be moved up and down with a tool post provided on a horizontal cross rail so as to be movable in the left-right direction, and a tool can be attached to the lower end of this ram. A is provided.

  Further, in a complex 5-axis machining apparatus, a column is generally provided so as to be movable in the Y-axis direction (front-rear direction) with respect to a column bed, and a horizontal cross rail as a lateral guide portion is provided on the column as a vertical guide portion. A vertical cross rail is provided as a guide so as to be movable in the Z-axis direction (vertical direction), and a tool post is provided to be movable in the X-axis direction (left-right direction) along the horizontal cross rail, or the horizontal cross rail is provided with an X-axis. A vertical cross rail is movably provided in the direction, and a tool post is provided on the vertical cross rail to be movable up or down, or a turret is simply provided on the horizontal cross rail so as to be movable in the X-axis direction. The provided ram is provided so as to be movable up and down, and a tool mounting portion is provided at the lower end of the ram. For example, when a tool is provided on the tool mounting portion so as to be tiltable in the left-right direction (B-axis indexing is possible). In addition, a turning table for setting a workpiece positioned below the tool is provided so that the C-axis can be freely indexed in the rotation direction. It is configured to allow multi-step processing.

  However, there is a tool that can be attached to and detached from the tool mounting part so that it can be tilted in the front-rear direction in the Y-axis direction (A-axis indexable) or tilted in the left-right direction in the X-axis direction (B-axis indexable). In addition, for example, there are some universal attachments that can be attached to and detached from the tool mounting part in the same way as other tools (other tool attachments), but in this way the universal attachment can be indexed. The swivel range is not large, and it cannot be rotated 360 degrees.

  In other words, the universal attachment with the indexable tool has a ram center (main shaft) and the transmission rotation shaft center (attachment main shaft) connected to the ram center. It is impossible to rotate 360 degrees to suspend the tool so that the shaft or B-axis can be indexed, and since it cannot be reduced in size, it can be automatically exchanged in the exchange tool magazine and exchanged automatically by an exchange device. It wasn't possible to make it fully automated.

The machining direction can be changed over a wide range, and of course, the milling function is maintained, and the rotary tool 7 is transmitted and rotated to perform milling in any direction of 360 degrees. Therefore, this is a universal attachment that can perform 5-axis combined machining, can perform small-diameter inner diameter machining, can be automatically changed by a structure that can be downsized, and can easily design movement control and tool change control. It will be an extremely innovative machine tool that can perform indexing over a wide range of 360 degrees.
