Problems solved by technology

The existing technology is not very reasonable in terms of structural rigidity, layout form, adjustment method, and manufacturability. During the drilling process, drilling vibration and noise will inevitably occur, and the shape and shape of the drilling surface cannot be guaranteed when the workpiece is drilled. Dimensional accuracy directly affects the performance and life of the machine tool

Abstract

The invention relates to a three-dimensional drill drilling head cross-shaped travelling mechanism. The travelling mechanism is characterized in that: the slide block and the guide rail of a longitudinal rolling linear guide rail assembly are respectively arranged on a spindle base mounting plate and a cross-shaped dragging plate, the lower end face of the spindle base mounting plate is provided with a nut base, the nut base is connected with one end of a longitudinal ball screw assembly, the other end of the longitudinal ball screw assembly is provided with a bearing, the bearing is arranged on a support unit base, the shaft end of the longitudinal ball screw assembly is in tight fit with a coupler by virtue of a square nut and a bush; the slide block and the guide rail of a transverse rolling linear guide rail assembly are respectively arranged on the cross-shaped dragging plate and a lathe bed, the lower end face of the cross-shaped dragging plate is provided with a transverse nut base, the transverse nut base is connected with a transverse ball screw assembly, one end of the transverse ball screw is arranged on a screw rear support base, and the shaft end of the transverse ball screw assembly is in tight fit with the screw rear support base. The invention has the advantages of more reasonable structure rigidity, arrangement, adjustment and manufacturability, good operation stability and high reliability.

Description

technical field [0001] The invention relates to a power traveling mechanism device of a three-dimensional drilling head, in particular to a cross traveling mechanism of a three-dimensional drilling head, belonging to the technical field of mechanical equipment. Background technique [0002] The transmission and guidance of the drilling head on the three-dimensional drill are key functional components, which directly reflect the accuracy and performance of the equipment. The existing technology is not very reasonable in terms of structural rigidity, layout form, adjustment method, and manufacturability. During the drilling process, drilling vibration and noise will inevitably occur, and the shape and shape of the drilling surface cannot be guaranteed when the workpiece is drilled. Dimensional accuracy directly affects the performance and life of the machine tool. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the ...
