Problems solved by technology

[0003] The invention provides a numerically controlled machine tool suitable for cutting super-long and super-heavy components such as magnetic levitation track beams. After the workpiece is in place, the machine tool itself can be adjusted so that the axis of the spindle is perpendicular to the surface of the workpiece to be processed, and straight workpieces can be processed. The technical problem of being able to process curved workpieces; and the technical problem of ensuring high positioning accuracy over the entire length of the workpiece

Embodiment Construction

[0017] See first figure 1 . As can be seen from the figure, the magnetic suspension track beam CNC machine tool of the present invention includes a bed 1, a column 8, a spindle box 5, a ram 4, a main shaft 11, a control system 9, and an operation station 16. It is characterized in that the bed 1 is 36 meters long, The upper full length of the bed 1 is provided with two linear rolling guide rails 17, and a row of precision racks 19 is fixed on the full length of the inner side of the bed 1. A column slide 2 is arranged on the linear rolling guide rail 17 of the bed 1, which can move along the entire length of the guide rail 17 through the transmission of the rack 19, forming the X-axis. The column slider 2 is equipped with an X-axis anti-backlash transmission mechanism and a B-axis rotary mechanism; a column swivel seat 3 is arranged on the column slider 2, and the B-axis rotary mechanism can rotate relative to the column slider 2 in a horizontal plane, forming a B shaft; Col...

Abstract

A numerally controlled machine-tool for machining the magnetically levitating rail is composed of main body with 36 m in length, vertical column, mainshaft box, control system and manipulating station. It features its other units including three drive mechanisms for X, A and B axises, a slide seat of vertical column, a rotary seat of vertical volumn and a slide saddle moving along vertical column. The said mainshaft box is arranged to slide saddle. The said control system and manipulating station are connected to slide seat. Its advantage is high precision in whole length range of workpiece.

Description

Technical field: [0001] The invention belongs to metal cutting machine tools, in particular to a metal cutting numerical control machine tool suitable for super-long and super-heavy components such as magnetic levitation track beams. Background technique: [0002] The prior art closest to the present invention is a floor-type CNC milling and boring machine. The layout and movement mode of the existing floor-type CNC milling and boring machine are that the column moves laterally on the bed to form the X-axis; the ram headstock moves up and down on the column to form Z axis; the longitudinal movement of the ram and the main shaft constitutes the Y axis. This layout and movement mode only has a linear axis, no rotary axis, and the moving range of the X axis is within 15 meters. This kind of floor CNC milling and boring machine generally adjusts the workpiece or uses a rotary table to adjust the machined surface of the workpiece to be perpendicular to the axis of rotation of the...
