V-shaped sliding rail device based on ultrasonic friction reduction

Abstract

The invention relates to the technical field of guide mechanisms, and particularly relates to a V-shaped sliding rail device based on ultrasonic friction reduction. The V-shaped sliding rail device comprises an upper guide rail, a lower guide rail and two ultrasonic vibrators symmetrically connected to the upper guide rail, wherein a V-shaped sliding groove is arranged in the bottom of the upper guide rail, the upper guide rail is clamped on the lower guide rail through the V-shaped sliding groove, and the upper guide rail can slide on the lower guide rail; the two ultrasonic vibrators are symmetrically connected to the two sides of the upper guide rail, and the two ultrasonic vibrators are electrically connected with an ultrasonic driving power supply through wires. According to the V-shaped sliding rail device based on the ultrasonic friction reduction, the ultrasonic vibrators are symmetrically connected to the two sides of the upper guide rail, the ultrasonic driving power supply drives the ultrasonic vibrators to work, the ultrasonic vibrators are symmetrical and simultaneously applies ultrasonic vibration to two sides of the upper guide rail, so that the upper guide rail is vibrated evenly and synchronously on the lower guide rail, the friction coefficient between the upper guide rail and the lower guide rail is effectively reduced, the motion resistance is reduced, so that the movement of the V-shaped sliding rail device is smoother, and the occurrence of cold welding, locking and the like is avoided.

Description

technical field [0001] The invention relates to the technical field of guide mechanisms, in particular to a V-shaped slide rail device based on ultrasonic friction reduction. Background technique [0002] The guide rail is one of the important components of the machine tool. It mainly plays the role of supporting and guiding the moving components to move along a certain track; there are many types of guide rails. Among the various types of guide rails, the sliding guide rail has simple structure, The advantages of good rigidity and high vibration resistance have been widely used in various machine tools. [0003] V-shaped guide rails are the most widely used among many sliding guide rails. The common lathe tailstock is guided by V-shaped guide rails; although the V-shaped sliding guide rail pair has good guiding accuracy, it also has a large friction coefficient and is prone to cold.

[0003] V-shaped guide rails are the most widely used among many sliding guide rails. The common lathe tailstock is guided by V-shaped guide rails; although the V-shaped sliding guide rail pair has good guiding accuracy, it also has a large friction coefficient and is prone to cold. For a series of problems such as welding and locking, people have come up with several methods to solve these problems:
