Stand column assembly for horizontal coarse framing machine

Abstract

The invention discloses a stand column assembly for a horizontal coarse framing machine. The stand column assembly includes a stand column and a spindle box arranged on one side of the stand column in a sliding manner, wherein a knife handle installing base is arranged on the spindle box; a spindle box guide groove is arranged on one side, close to the stand column, of the spindle box; two spindle box guide rails matched with the spindle box guide groove are arranged on the stand column along the length direction; the spindle box guide rails and the stand column are integrally molded by casting; the stand column includes two longitudinal beams which are parallel to each other and perpendicular to the ground, and two beams arranged at two ends of the longitudinal beams for connecting the two longitudinal beams; the longitudinal beams and the beams are all of hollow cylindrical structures, honeycombed reinforcing plate structures are arranged in the longitudinal beams and the beams, and a driving mechanism is arranged between the two longitudinal beams, and connected with the spindle box. According to the stand column assembly for the horizontal coarse framing machine, the stand column is of double-loop structure, the spindle box guide rail and the stand column are integrally molded by casting, the feeding travel of the blade is prolonged, and the machining of large workpieces is met, and meanwhile the spindle box guide rail of hard rail structure is high in accuracy and small in deformation.

Description

technical field [0001] The invention relates to the technical field of processing machine tools, in particular to a column assembly for a horizontal rough-frame machine. Background technique [0002] Milling machine is one of the commonly used equipment for rough frame processing in the machining industry. It mainly uses milling cutters to process various surfaces on workpieces. The main movement is the rotation of the milling cutter, and the movement of the workpiece or milling cutter is the feed movement. It can process Flat surfaces, grooves, and various curved surfaces can also be processed, and are widely used in machinery manufacturing and repair departments. [0003] Its general structure of the existing milling machine is a base, the base is provided with a fixed column, the fixed column has an extension arm, the main shaft and the vertical cutter are installed on the extension wall, and the cutter is fixed with the main shaft. Here, the tool works on the surface of...

Problems solved by technology

However, due to the heavy weight of the spindle box and the tool holder, most of the existing columns are formed by welding combined plates, and the guide rails are often linear guide rails. When this type of column supports the sliding spindle box, it is easy to produce a Stress concentration leads to deformation of the column, and the deformation of the column will cause deformation of the guide rail, which further affects the accuracy of the guide rail and the sliding of the headstock, and the linear guide rail is prone to transmission errors after a period of use, which affects the transmission accuracy of the headstock
