The invention discloses a cross beam high-load unloading device, and relates to the technical field of mechanical devices. The cross beam high-load unloading device comprises a cross sliding plate, wherein a rotating block support is arranged in an inclined hole in the cross sliding plate and is in clearance fit with the inclined hole of the cross sliding plate; a guide shaft is arranged at the upper end of the rotating block support, one end of the guide shaft is inserted into the rotating block support and is fixedly connected with a rotating block at the end part of the bottom end of the rotating block support, the rotating block is connected with a cross beam guide rail steel belt on a rail of a cross beam, the other end of the guide shaft is sleeved with a disc spring through a regulating nut, and the regulating nut is in threaded connection with an outer T-shaped supporting sleeve. An included angle between the axial line of the inclined hole of the cross sliding plate and the horizontal line is 75 degrees; and the guide shaft is fixed on the rotating block support through a pin shaft. The invention can solve the problem that the guide rail is easy to deform when the dead weights of the cross siding plate and a ram milling head are completely loaded on a reference guide rail of the cross beam.
Description
technical field [0001] The invention relates to the technical field of mechanical equipment manufacturing, in particular to an unloading device for a beam of a large gantry machine tool. Background technique [0002] At present, large-scale gantry machine tools with movable beams are used in many cases for the processing of large workpieces. In order to meet the processing requirements of high power and high torque, the beam guide rails are mostly designed as stepped rectangular guide rails. In order to ensure the machining accuracy, the frame rigidity of the machine tool is greatly enhanced, and the dead weight of the horizontal slide plate and the ram milling head is significantly increased, resulting in a series of problems: [0003] 1. The self-weight of the transverse slide plate and the milling head of the ram are all loaded on the beam reference guide rail, which greatly increases the load on the support surface of the beam reference guide rail and easily causes defo...
