Thermal deformation suppression middle type high-speed crown block gantry five-axis machining center

Abstract

The invention discloses a thermal deformation suppression middle type high-speed crown block gantry five-axis machining center. A workbench is directly cast on a base; a left bridge and a right bridge are installed on the two sides of the base; linear guide rails are installed on the left bridge and the right bridge correspondingly; a cross beam is installed on the left bridge and the right bridge through X-axis sliding blocks on the two sides; the middle of the cross beam is hollowed-out; four guide rails are arranged on the upper side and the lower side of the cross beam; and a left sliding base and a right sliding base are installed in the middle of the cross beam through the sliding blocks. A left ram and a right ram are connected into a whole through a Y-axis sliding block and a connection board, four linear guide rails are arranged on the rams, and the rams are installed in the middle of the left sliding base and the right sliding base through Z-axis sliding blocks. The middle type design of the movement components in the thermal deformation suppression middle type high-speed crown block gantry five-axis machining center effectively conduct temperature rise generated by movement, so that structural deformation is uniform and influence of thermal deformation on the precision machining of products is reduced. The thermal deformation suppression middle type high-speed crown block gantry five-axis machining center is stable in operation and performance and suitable for precision machining in the automotive die field.

Description

technical field [0001] The invention belongs to the field of high-speed crane gantry five-axis machining center machine tools, in particular to a mid-mounted high-speed crane gantry five-axis machining center for suppressing thermal deformation, which is specially used for processing precision molds in the automobile industry. Background technique [0002] In recent years, the continuous development of the manufacturing industry has put forward higher requirements for the processing range and machining accuracy of the five-axis machining center machine tool. In the traditional high-speed gantry five-axis machining center, the X-axis generally adopts rack drive, which has poor transmission accuracy and unstable operation. Stablize. The workpiece moves on the table, and high-speed processing cannot be achieved for large and heavy parts. Moreover, due to the large amount of heat generated during the machining process, the machine tool is thermally deformed, which cannot provid...
