Problems solved by technology

Germany has introduced a three-axis parallel vertical CNC lathe. The turning spindle head is installed on the moving platform of the parallel mechanism. The workpiece is installed on the three-jaw chuck at the front end of the spindle. The moving platform moves along the three coordinate axes. move, so it can only be used for processing small disk parts

Embodiment 1

[0020] The motor of the turning spindle head 1 is an AC servo main motor with C-axis function, the spindle head (7) adopts a frequency conversion electric spindle, the tool holder 4 is a turret-type turning tool holder, and the parallel mechanism of the milling tool holder 8 is a 3-PRS mechanism , Each feed motor is a servo motor. The machine tool can realize up to six-axis linkage. The large gantry 12 is installed on the bed 2, and the small gantry 10 is installed on the bed saddle 3, moves longitudinally together with the bed saddle 3, and is connected with the large gantry 12 with guide rails, so that the whole machine tool forms a closed loop circuit structure, rigid high. A standard floor tool magazine is installed on the side of the machine tool.

Embodiment 2

[0022] The difference from Embodiment 1 is that the milling spindle head 7 adopts a servo electric spindle, which adds special slot processing functions, such as inclined slots in different orientations.

Abstract

A dual-gantry combined horizontal numerally controlled machine-tool able to perform turning, milling, drilling, reaming, boring, etc is composed of two mainshafts for turning and milling, two tool carriages for turning and milling, small and big gantries, main body, saddle, two longitudinal slide plates and tailstock. Its advantages are high machining precision, and high rigidity.

Description

technical field [0001] The invention relates to a numerical control cutting machine tool, in particular to a double-gantry horizontal mixed-connection principle turning-milling compound numerical control machine tool which uses both serial and parallel connections. Background technique [0002] The traditional machine tool is based on the principle of complete serial connection, which has the advantages of large working space and simple motion algorithm of the machine tool; the disadvantage is that the motion errors of each axis accumulate, the cantilever structure has weak rigidity, the motion mass is large, and the speed cannot be too high. In recent years, the United States has first introduced a six-axis fully parallel machine tool, also known as a virtual axis machine tool or a hexapod parallel machine tool. The space is small and the motion algorithm is complex. At present, in addition to realizing the advantage of fast speed, the fully parallel machine tools develope...
