AI Technical Summary

Technical Problem

In the double spindle CNC lathe on the inclined bed, linear guide rails are prone to wear, while the hard rails move too slowly, resulting in machine tool accuracy and low production efficiency.

Method used

Combined guide rails are adopted, including integrated hard rails and half-wire rail sleeves. The hard rail friction part is at a high position. The ball moves along the half-wire rail sleeve to change the spacing and oil is discharged to the hard rail friction part, increasing the lubrication effect, reducing wear, and returning oil Components and protective components enable continuous lubrication and protection.

Benefits of technology

It delays the wear of linear guide rails, improves the movement speed of hard rails, and enhances the accuracy and production efficiency of the machine tool.

Abstract

The present invention discloses a slant bed double-spindle CNC lathe, comprising a slant bed frame, and also comprising a combined guide rail arranged on the slant bed frame, the combined guide rail comprising: an integrated hard rail, on which a half-line rail sleeve and a hard rail friction part are symmetrically arranged, and the hard rail friction part is located at a high position; a combined guide sleeve, which is movably arranged on the integrated hard rail; a lubricating moving block, in which a plurality of balls are movably arranged in a linear array, and the plurality of balls change the spacing along the half-line rail sleeve as the combined guide sleeve moves along the half-line rail sleeve. The slant bed double-spindle CNC lathe provided by the present invention arranges the half-line rail sleeve on the integrated hard rail, and the hard rail friction part is used as the pressure-bearing part with the greatest pressure to withstand the inclined pressure. Compared with the linear guide rail under pressure, the wear speed of the plane is slower, and the half-line rail sleeve is arranged at a low position with less pressure, which can avoid wear while reducing the friction surface with the integrated hard rail, so as to increase the moving speed of the combined guide sleeve.
