Combinded processing lathe and its tool post

Abstract

The invention relates to a compound working lathe and turrets thereof. Turrets (11, 12), which can rotate about a common axis (y-y) and on the outer peripheral surfaces of which a plurality of tools (15) are radially installed, are disposed along the axis (y-y) in a turret housing (100). Respective turrets (11, 12) can be dividedly rotated by separate turret driving motors (13, 14).

Description

technical field [0001] The present invention relates to a compound machining lathe for performing multiple different machinings on workpieces, and a tool holder installed on the lathe and capable of selecting and holding various tools used for machining. Background technique [0002] Generally, a lathe performs machining by bringing a tool such as a turning tool into contact with a workpiece that is rotationally driven by a spindle, that is, a workpiece. [0003] Furthermore, lathes that perform multiple different processes on workpieces, that is, composite processes, are often used. For example, various lathes and machine tools disclosed in Patent Documents 1 to 5 are well known.

AI Technical Summary

Problems solved by technology

[0025] However, with this turret, since each turret cannot be indexed independently, it is also not possible to index the other turret while machining with a tool in one turret. Rotate, no pre-selection of the tool to be used for subsequent machining

[0026] Therefore, none of the above devices can sufficiently shorten the non-machining time, that is, the time required for tool selection, and cannot sufficiently shorten the time required for machining each workpiece.

In addition, from the perspective of processing freedom, there are many restrictions

[0027] As mentioned above, none of the conventional compound machining lathes can shorten the time required to select a tool through its tool holder, or the degree of freedom in machining is insufficient, and there is a limit to shortening the time required for machining each workpiece.
