Precise numerical control internal grinder and processing control method thereof

Abstract

The invention discloses a precise numerical control internal grinder and processing control method thereof. The grinder comprises a grinder body, a grinder head, a grinding module and an electric control gear. The grinder also comprises a transverse slide mechanism and a longitudinal slide mechanism, wherein, each set of slide mechanism is driven by a servo motor and adopts a ball screw for transmission. The grinder head is arranged on a sliding plate of the transverse slide mechanism. The grinding module also comprises an inner hole grinding module and a conical surface grinding module, wherein, each set of grinding module is respectively arranged on the sliding plate of the longitudinal slide mechanism by a set of independent grinding sliding plate mechanism, and each set of grinding module all comprises a set of independent reciprocating driving mechanism, a grinding tool and a grinding tool rotation drive mechanism. The method refines the processing process and sets proper processing parameter according to best grinding technical curve. A programmable controller finishes accurate grinding processing according to reliable parameter. The invention can improves the processing efficiency and precision of an internal grinder and is particularly fit for parts with inner holes and the conical surfaces which are required to be ground accurately.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a machining control method for a numerically controlled precision internal grinder. Background technique [0002] Many mechanical parts have high processing precision requirements, which cannot be met by ordinary grinding machines. For example, the fuel injector parts on diesel engines are characterized by high requirements on the shape accuracy of the inner hole and the inner cone surface, the concentricity of the hole and the cone surface, and the surface roughness. In the prior art, for the finishing of the inner hole and the conical surface of the fuel injection nozzle parts similar to diesel engines, there are boring + grinding processes, and there are also hydraulic mechanical double-station grinding machines; + The disadvantage of the grinding process is low efficiency and difficult cleaning. The disadvantages of the hydraulic-mechanical double-station grinding machine...
