Two-axis linkage numerical control grinding machine with double spindles

Abstract

The invention provides a two-axis linkage numerical control grinding machine with double spindles. The machine provided by the invention comprises a base, a workpiece spindle box and a grinding head spindle base arranged on the base, a workpiece and a work-piece spindle arranged on the workpiece spindle box, a longitudinal support plate arranged on the base through a longitudinal guide rail, and a transverse support plate arranged on the longitudinal support plate through a transverse guide rail, wherein the grinding head spindle base is arranged on the transverse support plate; and the grinding head spindle base is provided with a grinding head spindle. In the two-axis linkage numerical control grinding machine with double spindles provided in the invention, the prior numerical control art is effectively utilized, the machining operations is reduced, the grinding processes for grinding an inner hole and chamfering the mouth rounded corner of the inner hole for one time are realized, and the target that the outline and the size of the mouth rounded corner of the grinded inner hole are consistent is achieved. Furthermore, the rotation speed of the grinding head spindle is adjustable so as to be adaptable to the surface quality requirements of the inner holes the hole diameters of which are different from small to large, and the chamfered corner.

Description

technical field [0001] The invention relates to the technical field of numerical control inner hole and rounding grinding, in particular to a double-spindle and two-axis linkage numerical control grinding machine applied to the numerical control inner hole and rounding grinding technology. Background technique [0002] The existing inner hole and chamfering processing technology first uses a tool grinder to rotate the grinding head by 45° to perform 45° chamfering, and then rounds it with a file. In the prior art, chamfering is performed first and then rounding, which involves many procedures and low efficiency; moreover, rounding is carried out manually with a file, so the shape and size of the arc profile surface are irregular and poor in consistency. For example, the processing of the rounded corners of the orifice in the drawing die, the shape and size of the arc contour surface are irregular, and the consistency is poor, which will easily cause holes and cracks when the...
