Intermediate grinding wheel double-rod inner thread grinder structure

Abstract

The application discloses a kind of inner thread grinding machine structures of intermediate grinding wheel double outlet rod, belong to precision grinding tooling technical field, including bed, support component, sliding component, front and rear sliding mechanism, grinding rod and the workpiece clamping assembly independently arranged in the most front end of bed, grinding rod middle section is fixed with grinding wheel, right end is fixedly connected with sliding component.Support component and sliding component are all assembled on front and rear sliding mechanism, can be synchronous front and rear sliding, in grinding state, the left and right ends of grinding rod are respectively constrained by support component and sliding component, form double-end closed loop rigid support, grinding wheel keeps stationary locking in axial direction;The front and rear sliding of workpiece clamping assembly's front and rear sliding table drives workpiece spindle and workpiece along left and right direction follow-up sliding, workpiece spindle drives workpiece rotation, with the axial feeding linkage interpolation of front and rear sliding table, form relative to fixed grinding wheel Compound spiral grinding trajectory, eliminate grinding rod cantilever flutter, improve precision and processing efficiency.
