Internal and external thread grinding machine capable of realizing in-situ modification of grinding wheel

Abstract

The invention provides an internal and external thread grinding machine capable of realizing in-situ modification of a grinding wheel. An A-shaft rotary table (10) is arranged on a rotary table base (11); the A-shaft rotary table (10) can rotate on the rotary table base (11); a rotating shaft is defined as a shaft A and rotates in the X-axis direction; a large-diameter grinding wheel can be installed on a grinding wheel headstock (6); angle adjustment of the large-diameter grinding wheel or a small-diameter grinding wheel is achieved through the rotating shaft A; a shakable angle dresser (8) is fixed to the side surface of a workpiece headstock (4) and is used for generating a certain oscillation angle; the shakable angle dresser (8) consists of a rolling wheel rotating mechanism (81), anoscillation angle guide mechanism (82) and an angle driving mechanism (83); the oscillation angle guide mechanism (82) and the angle driving mechanism (83) are both installed at the side surface of the workpiece headstock (4); the rolling wheel rotating mechanism (81) is installed on the oscillation angle guide mechanism (82); the angle driving mechanism (83) can be used for driving the oscillation angle guide mechanism (82) to rotate; and the rolling wheel rotating mechanism (81) can be used for trimming a large-diameter grinding wheel installed on the grinding wheel headstock (6) or a small-diameter grinding wheel installed on an inner grinding head component (12) to realize in-situ modification of the grinding wheel.

Description

technical field [0001] The invention relates to an internal and external thread grinding machine capable of in-situ modification of a grinding wheel, and belongs to the technical field of internal and external thread grinding machines capable of in-situ modification of a grinding wheel. Background technique [0002] Thread grinding equipment is the key equipment for precision thread processing. It is mainly used for precision machining of important thread measuring tools and parts such as thread measuring tools, thread tools and lead screws. Thread grinding machines are special-purpose machine tools with fixed functions and structures, and are mainly used for dressing single-profile grinding wheels. Therefore, for grinding machines used for internal or external thread grinding, the layout and structure of the dressing mechanism are very different. The dressing mechanism of the traditional external thread grinder is arranged on the upper part of the grinding wheel head frame,...

AI Technical Summary

Problems solved by technology

The repeated swing angle grinding wheel dressing method adopted in the existing technology will introduce repeated positioning errors, and will reduce the rigidity of the grinding wheel headstock, which will affect the final thread grinding accuracy
