Double-spindle movable gantry ultra-long stroke machining center used for drilling and milling steel rail joint part

Abstract

The invention provides a double-spindle movable gantry ultra-long stroke machining center used for drilling and milling a steel rail joint part. A gantry frame is arranged on a machine body; a main machining side slide seat and a main machining side spindle box are placed above one side of the machine body; a sub machining side slide seat and a sub machining side spindle box are placed above the other side of the machine body; a fan-shaped servo tool magazine is arranged between the main machining side spindle box and the sub machining side spindle box; an operation platform is arranged on thetwo sides of the machine body; the length of the single machine body is 6m and adopts a structural form of a spliced machine body; the machine body length of a single machine is 30m and the machine body of the single machine can extends for a longest distance of 54m; a gantry is single side drive; and a main guide machining side adopts a linear guide rail with pre-tensioning. The double-spindle movable gantry ultra-long stroke machining center used for drilling and milling the steel rail joint part has the advantages that the blank of special steel rail machining equipment is filled, 27m longsteel rail can be machined at one time, the machine can extend for a longest distance of 54m, and the equipment operation difficulty is reduced. The problem that the repeated positioning accuracy islow due to large parallelism error between two linear guide rails of a traditional structure in a long stroke is solved; and the machining efficiency is enhanced.

Description

technical field [0001] The present invention relates to the layout structure field of double-side hanging box opposite dual-spindle dynamic gantry ultra-long stroke machining center used for drilling and milling of rail joints, and in particular relates to a double-spindle dynamic gantry super-long for drilling and milling of rail joints Stroke machining center. Background technique [0002] The rails used in high-speed railways and intercity rails are all segmented, and are reassembled at the construction site, so the rails need to be pre-drilled, milled, chamfered, etc. The current equipment used is non-professional processing equipment. The processing efficiency and degree of automation are low. Contents of the invention [0003] The object of the present invention is to solve the problems of low automation and low efficiency of processing rails by existing numerical control equipment, and it is impossible to complete the processing in one clamping, and specially provi...
