Two-sided lathe bed miller

Abstract

The invention relates to a double-sided bed-type milling machine. Two sides of a machine bed are symmetrically provided with a set of milling units; each milling unit consists of an upright post, a slide carriage, a slide ram and a horizontal type mainshaft; the upright post is vertically close to the machine bed; a worktable which moves along an X direction is arranged on the machine bed; the slide carriage is arranged on the upright post and moves along a Y direction; the slide ram is arranged on the top of the slide carriage and moves along a Z direction; the horizontal type mainshaft is arranged inside the slide ram along the Z direction; a cross beam is connected between the tops of two side upright posts; the two side upright posts and the cross beam form a high-rigidity gantry frame; the movement and rotation of the worktable, the slide carriage, the slide ram and the horizontal type mainshaft are driven by a servo motor controlled by a numerical control system; two sets of the milling units are respectively provided with a tool magazine; an automatic reblading system of the tool magazine is controlled by the numerical control system; in order to fit the use of a full automatic hydraulic clamp in the double-sided bed milling machine, an X-direction rectangular guide rail and an X-direction hill-type guide rail are also arranged on the worktable. The double-sided bed-type milling machine has good rigidity and large three-way stroke and can once carry out the machining processes of milling, boring and drilling to a horizontal type workpiece.

Description

(1) Technical field: [0001] The invention relates to a machine tool, in particular to a double-sided bed milling machine. (two) background technology: [0002] In order to adapt to different processing ranges and processing conditions, there are a variety of milling machines with the same layout and structure, such as gantry milling machines, single-arm milling machines, horizontal single-sided bed milling machines, etc. limitation. [0003] Such as single-arm milling machines, horizontal single-sided bed milling machines can only process on one side, the process range is narrow, and the efficiency is low; such as gantry-type milling machines, most of the milling heads are vertical structures, even if a right-angle milling head is used, the vertical When the structure is transformed into a horizontal type, the transmission rigidity is reduced, which greatly reduces the cutting rigidity and strength, and affects the processing efficiency. [0004] For processing with strong...
