Vertical internal and external grinding machine capable of simultaneously grinding internal and external circles

Abstract

The invention discloses a vertical internal and external grinding machine capable of simultaneously grinding internal and external circles. The vertical internal and external grinding machine comprises a machine body base, wherein a stand column is fixedly installed on one side of the machine body base, a rotary workbench is fixedly installed on the other side of the machine body base, a pluralityof horizontal linear guide rails are fixedly installed on the vertical side wall of the side, facing the rotary workbench, of the stand column at equal intervals, the vertical side wall of the standcolumn is further fixedly provided with horizontal ball screws on the upper side and the lower side of the horizontal linear guide rail located in the middle respectively, and two horizontal moving dragging plates are further arranged on the linear guide rails in a sliding mode. In order to overcome the defects in the prior art, the vertical internal and external grinding machine capable of simultaneously grinding the internal and external circles is designed, four pairs of feeding shafts in the vertical direction and the horizontal direction are designed, and an inner hole grinding head bodyand an external grinding head body can be driven to simultaneously machine the internal diameter and the external circle of a tubular workpiece; and meanwhile, the upper end face can be machined.

Description

technical field [0001] The invention relates to the field of numerical control grinding machines, in particular to a vertical inner and outer cylindrical grinding machine capable of simultaneously grinding inner and outer circles. Background technique [0002] Most of the existing grinding machines are single-sided grinding machines and need to be fixed by fixtures. Not only is the assembly troublesome when processing tubular workpieces, but also the workpiece must be removed after the inner diameter has been processed after assembly, and then assembled to another grinding machine for the precision of the outer wall and end surface of the workpiece. processing. [0003] As a result, the process flow is complicated and the processing efficiency is low. Contents of the invention [0004] The object of the present invention is to provide a vertical inner and outer cylindrical grinding machine capable of simultaneously grinding inner and outer circles, so as to solve the prob...
