Centerless grinding machine for tungsten-steel rod diameter processing

Abstract

The invention relates to the technical field of machining, and discloses a centerless grinding machine for tungsten-steel rod diameter processing. The centerless grinding machine comprises a grindingwheel and a guide wheel which are mounted on a grinding machine base, wherein the grinding wheel and the guide wheel rotate through transmission of a transmission shaft; a splicing grinding wheel stone bar is arranged on an anti-jumping plate for grinding and limiting above a tungsten-steel rod, so that on one hand, single-point grinding of the tungsten-steel rod is changed into dual-point grinding, the tungsten-steel rod is supported in multiple directions in a grinding process, the tungsten-steel rod is more stable during grinding, jumping, in the perpendicular direction, of the tungsten-steel rod is reduced, and grinding amount at the two ends of the tungsten-steel rod is guaranteed to be consistent; secondly, the splicing grinding wheel stone bar can share one part of grinding effect,so that one part of grinding amount of the grinding wheel is shared, and therefore, the tungsten-steel rod is grinded in multiple directions simultaneously, and grinding effect is more uniform and ismore stable; and meanwhile, abrasion loss on front and rear ends of the grinding wheel is relatively uniform, and effective grinding time, on the tungsten-steel rod, of the grinding wheel can be keptall the time, so that grinding effect is improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a centerless grinder for machining tungsten steel rod diameters. Background technique [0002] Centerless grinding machine is a type of grinding machine that does not need to use the axis positioning of the workpiece for grinding. It is used for grinding slender cylindrical workpieces, including tungsten steel rods. The centerless grinding machine is mainly composed of grinding wheels and guide wheels. It is composed of three mechanisms with the workpiece support, in which the grinding wheel is actually responsible for the grinding work, the guide wheel controls the rotation of the workpiece, and controls the feed speed of the workpiece (the axial feed is realized by adjusting the small inclination angle of the axis of the guide wheel) , the workpiece support supports the workpiece during grinding, and the specific structure is attached Figure 5 As shown, when the tungsten ste...

AI Technical Summary

Problems solved by technology

[0003] In view of the deficiencies of the above-mentioned background technology, the present invention provides a centerless grinding machine for machining tungsten steel rods, which is more stable when grinding tungsten steel rods, the grinding quality is better, and the single-point grinding amount of the grinding wheel is small. The degree of wear of the grinding wheel is uniform, and the temperature of the tungsten steel rod is relatively uniform during grinding, which solves the problems raised by the background technology
