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...

Embodiment Construction

[0018] The double-sided bed milling machine of the present invention includes a bed 2, a workbench 1 that moves left and right along the guide rail along the guide rail on the bed 2, and two sets of milling units arranged on both sides of the bed 2, such as figure 1 , figure 2 shown.

[0019] exist figure 1 Among them, each milling unit includes column, slider, ram and horizontal spindle. According to the orientation, the left milling unit includes left column 4, left slider 6, left ram 8 and left horizontal spindle 10, and the right milling unit The unit includes a right column 5, a right sliding seat 7, a right ram 9 and a right horizontal main shaft 11. The left column 4 and the right column 5 are vertically fixed, and the tops of the two are connected with a beam 3 to form a high-rigidity gantry frame, and a guardrail 14 is arranged on the beam 3 . exist figure 2 Among them, the right sides of the left column 4 and the right column 5 are provided with parallel vertic...
