Multi-axis spindle sleeve grinding process and special grinding machine thereof

Abstract

The invention provides a multi-axis spindle sleeve grinding process and a special grinding machine thereof. Before grinding of a spindle sleeve is started, a left inner circle grinder and a right inner circle grinder of which the axes are not located on the same axial line are amended through a diamond pen, so that machine assembling errors, mechanical accumulated error and grinding wheel size differences are effectively avoided. Due to the fact that grinding wheels are amended through the diamond pen, unification of the heights of grinding points of the grinding wheels can be guaranteed, andunder the condition that the spindle sleeve is clamped once, the coaxiality of inner holes in two ends and the perpendicularity of the inner end faces of the inner holes are ensured during grinding ofthe spindle sleeve.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a multi-axis spindle sleeve grinding process and a special grinding machine tool thereof. Background technique [0002] During the processing of the spindle sleeve, it is necessary to use a grinding machine to grind and correct the inner wall of the sleeve. For the grinding of the left inner hole and the right inner cylinder of the sleeve, they need to be clamped to the corresponding grinding machine respectively. on for processing. When the inner wall of the sleeve is as image 3 The inner hole on the left side and the inner hole on the right side shown are coaxial and have the same diameter. When the inner end surface of the inner hole is vertical, it is processed by ordinary grinding machine tools. Due to the need for multiple clamping, the clamping error will affect the The accuracy of the sleeve. When there is a difference between the assembly error of the ma...

Problems solved by technology

When the inner wall of the sleeve is as image 3 The inner hole on the left side and the inner hole on the right side shown are coaxial and have the same diameter. When the inner end surface of the inner hole is vertical, it is processed by ordinary grinding machine tools. Due to the need for multiple clamping, the clamping error will affect the The accuracy of the sleeve

When there is a difference between the assembly error of the machine tool and the cumulative mechanical error or the size of the grinding wheel, the accuracy of the sleeve cannot meet the processing requirements

It is necessary to use a grinding machine with higher precision and carry out precise calibration on the grinding machine to ensure that the grinding points of the grinding wheels of each spindle head are highly uniform after calibration, so as to ensure the machining accuracy of the sleeve, which is costly
