Large-span integrated beam structure of gantry machine tool and manufacturing method

Abstract

The invention discloses a large-span integrated beam structure of a gantry machine tool and a manufacturing method. The large-span integrated beam structure is characterized in that a whole back panelis welded with one side of the spaced support end of a beam rib plate, and a frame panel and a core panel of a front panel are welded with the end face of the other side of the beam rib plate and then are welded with two end plates, a column mounting panel and a connection plate. The front panel comprises the frame panel and the core panel, and a square window is reserved in the center of the frame panel. The size of the core panel is same as the size of the square window in the frame panel, and a slotted hole is formed in the width direction of the core panel. The back panel is formed by oppositely bending a whole steel plate four times continuously according to the section edge shape of a beam, wherein two short edges sharing a vertical edge are opposite, the steel plate is bent and extends to the length of the whole beam, and the inner surfaces of the two short edges are welded on a guide rail mounting surface of a beam frame. The shape of the end plates is consistent with the shape of the whole surface formed by combining the front panel, the back panel, the beam frame and the beam rib plate and then combining the whole with the edge of a column combination surface protrudingplate, and the end plates are welded with the two ends of the beam combined with a column combination surface protruding part, the front panel and the back panel.

Description

technical field [0001] The invention relates to the manufacture of mechanical equipment in the processing field, and relates to a large-span integrated beam structure and a manufacturing method of a gantry machine tool. Background technique [0002] At present, the long-span beam structure supported by the gantry machine tool with a length of more than 4 meters is divided into two types according to the different molding methods. One is the casting molding structure. The large beam is cast by resin sand wood molding process or lost foam process. Good performance, but the weight of the beam is not easy to control. Taking the 6.2-meter-long beam as an example, the weight exceeds 15 tons, which is not conducive to lightweight design, affects the dynamic characteristics and speed of the whole machine, and is prone to many casting defects, and the production cycle is long; another The first is a welded forming structure. The beam is integrally welded with high-strength steel. It ...
