Moving post double-side ram lathe body milling machine

Abstract

The invention discloses a moving post double-side ram lathe body milling machine, which comprises a work bench base mounted to a ground foundation, left and right upright posts arranged at the left and right sides of the work bench base, left and right lifting slide seats arranged on the left and right upright posts, left and right rams arranged on the left and right lifting slide seats, left and right main shafts mounted to front ends of the left and right rams, and left and right mill heads mounted to the left and right main shafts, wherein the left and right upright posts are respectively mounted in position through left and right longitudinal orientation guide rails and left and right longitudinal auxiliary guide rails; the left and right longitudinal orientation guide rails are arranged on two steps inwardly formed on the left and right side faces of the work bench base in a manner of being higher in the front position and lower in the back position; and the left and right longitudinal auxiliary guide rails are mounted on the ground foundation and do not need limiting in the horizontal direction. By adopting the moving post double-side ram lathe body milling machine provided by the invention, the support span of the double upright posts can be increased to obtain higher support stability and effectively prevent disturbing moment produced by forward tilting of the gravity center of the upright posts due to forward movement of the rams.

Description

(1) Technical field: [0001] The invention relates to a metal processing machine tool, in particular to a double-sided ram bed milling machine with a moving column. (2) Background technology: [0002] In order to meet the needs of large longitudinal processing range and small installation space processing conditions, some types of milling machines with layout structures include moving column type gantry milling machines, moving column type bed milling machines, etc. The structure in which the vertical column and the workbench are independently installed on the foundation has the disadvantages of large footprint of the machine tool, great influence of the installation foundation, difficulty in installation and debugging, and large changes in accuracy maintenance due to various factors, requiring regular adjustments, etc. factor. (3) Contents of the invention: [0003] The present invention proposes a moving column double-sided ram bed milling machine, the purpose of which i...
