Center complete machine for internal thread grinding

Abstract

The invention relates to a central complete machine for internal thread grinding. The central complete machine for internal thread grinding is characterized by comprising a bed, a linear roller guide is arranged above the left side of the bed, a cross table is mounted on a slider of the linear guide rail, a headstock is fixed on the cross table, a workpice clamping device is fixed on a spindle end face of the headstock, an internal thread grinding wheel dressing mechanism is fixed right ahead a shell of the headstock, an external-grinding grinding wheel dressing mechanism is fixed right astern the shell of the headstock, a grinding carriage mounting body is fixed on the right surface of the bed, a grinding carriage for internal thread grinding is fixed right ahead the grinding carriage mounting body, a grinding wheel spindle for internal thread grinding is fixed in a shell of the grinding carriage for internal thread grinding, a grinding carriage for external grinding and face grinding of nuts is clamped right astern a fixed mounting body of the grinding carriage for internal thread grinding through T-slot nuts and bolts, a grinding wheel spindle for external grinding and face grinding of the nuts is fixed in a shell of the grinding carriage for external grinding and face grinding of the nuts, and a measuring device is fixed on the top. The central complete machine for internal thread grinding is high in production efficiency and machining precision.

Description

technical field [0001] The invention relates to the field of metal cutting machine tools, in particular to an internal thread grinding center complete machine for grinding the outer circle, end face and internal thread of nuts. Background technique [0002] The nut is an important component of the screw drive, and the outer circle, end face and inner thread of the nut need to be precision ground. The dimensional accuracy, position accuracy, shape accuracy and surface quality of nuts determine the success or failure of nut processing, and also determine the quality and cost of nut processing. [0003] The existing traditional nut processing technology adopts multiple clamping and multiple grinding processes. The outer circle, end surface and internal thread of the nut are processed multiple times on different machine tools. The production efficiency is low and the processing accuracy is not high, especially in When grinding the ball nut thread raceway of the ball screw pair,...

Problems solved by technology

[0003] The existing traditional nut processing technology adopts multiple clamping and multiple grinding processes. The outer circle, end surface and internal thread of the nut are processed multiple times on different machine tools. The production efficiency is low and the processing accuracy is not high, especially in When grinding the ball nut thread raceway of the ball screw pair, it is impossible to ensure that the hole of the return guide device is in the center of the thread raceway, the dimensional consistency is poor, the position accuracy and shape accuracy are unstable, and the scrap rate is high
