Adjustable floating supporting device and adjusting method

Abstract

The invention provides an adjustable floating supporting device and an adjusting method, and aims to solve the problem that in the prior art, the precision is not high because a fixture remains stationary during a bearing machining process. The adjustable floating supporting device comprises a workpiece and a grinding wheel, wherein a fixed support is arranged at the bottom of the outer side of the workpiece; a floating support is arranged at the right part of the outer side of the workpiece, and comprises an upper floating head, a lower floating head and a floating supporting seat; a mounting hole I is formed in the left side of the floating supporting seat; fixing holes are formed in the right side of the floating supporting seat; spring fixing holes I are formed in both the top surface and the bottom surface of the right side of the floating supporting seat; and a spring fixing hole II is formed in the top surface of the upper floating heat. The adjustable floating supporting device provided by the invention has the advantages that the floating supporting design is adopted; when being machined, the workpiece rotates along with the clockwise direction shown in figure 1; the workpiece is machined under the grinding action of the grinding wheel, thereby greatly improving the machining precision; and the circumstance that the machining precision is lowered and the normal use is influenced because the error of a bulge is reflected on an inner hole of the workpiece when the bulge is formed on the outer cylindrical surface of the machined workpiece is avoided.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to an adjustable floating support device and an adjustment method. Background technique [0002] Electromagnetic centerless fixture is a processing technology widely used in bearing grinding. Its working principle is to rely on electromagnetic force to absorb the end face of the workpiece to be processed to the end face of the fixture drive installed on the spindle of the machine tool. The eccentricity between the workpiece center and the rotation center of the fixture drive end face installed on the machine tool spindle, so that the outer circular surface of the workpiece to be processed is close to the upper and lower supports installed on the fixture, such as when grinding the inner circle of the bearing inner ring , is to close the end face of the workpiece and the driving end face of the fixture, and support the outer cylindrical surface of the inner ring to grind the inner...
