Fixing mechanism for hollow ball screw pair

Abstract

The invention discloses a fixing mechanism for a hollow ball screw pair. The fixing mechanism comprises a front supporting base, a rear supporting base, a front supporting unit sleeve, a rear supporting unit sleeve, triple bearings, a front sealing unit, a front anti-collision ring, a rear anti-collision ring and a cooling system. The tail end of the hollow ball screw pair penetrates through the rear anti-collision ring and then is fixedly connected to the rear supporting unit sleeve through the triple bearing at the rear. The front end of the hollow ball screw pair penetrates through the front anti-collision ring and the front sealing unit and then is fixedly connected to the front supporting unit sleeve through the triple bearing at the front. An oil inlet and an oil outlet in the two ends are connected with an oil inlet pipe and an oil outlet pipe respectively. The fixing mechanism is simple in structure, convenient to install and capable of providing a reliable and precise operation platform for operation of the hollow ball screw pair, reducing machining errors of a numerically-controlled machine tool and improving precision.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment and relates to a fixing mechanism for a hollow ball screw pair. Background technique [0002] The ball screw pair is one of the core components of the CNC machine tool. After the ball screw pair moves, it will heat up, the whole body will elongate, and the pitch error will become larger. With the development of machine tools towards high precision, the problem of heat elongation and deformation of lead screws has attracted more and more attention from machine tool designers. The hollow ball screw pair can reduce the moment of inertia and reduce the pitch error of the screw pair due to heating, so it is more and more used in the field of machine tools. However, the hollow ball screw pair needs to be fixed by a special fixing mechanism on the CNC machine tool to provide accurate parameters for the design of the machine tool. At present, the research on the fixing mechanism of the hollo...
