A high-precision double-measuring-point device for online measuring large-scale dimensions of workpieces in a vertical grinder

Abstract

The application relates to a high-precision double-measuring-point device of a vertical grinder for measuring a large-range size of a workpiece online, which comprises a stand column, a height large-range adjusting mechanism arranged on the stand column, a height reciprocating moving mechanism and a height positioning assembly arranged on the moving end of the height large-range adjusting mechanism, a horizontal longitudinal moving mechanism arranged on the moving end of the height reciprocating moving mechanism, a horizontal transverse moving mechanism installed on the moving end of the horizontal longitudinal moving mechanism, and an inner-outer diameter measuring instrument installed on the moving end of the horizontal transverse moving mechanism; the height large-range adjusting mechanism comprises a large slide plate, an adjusting guide mechanism, an adjusting driving mechanism and an adjusting locking mechanism; adjusting trapezoidal grooves are vertically arranged on the stand column, and the trapezoidal grooves are divided into two layers, wherein the upper layer is an adjusting guide groove; and the adjusting guide mechanism comprises an adjusting guide pin. The application has high measuring precision, stable size control and small influence of external factors.
