Grinding method for external diametral plane large circular arc

Abstract

The invention relates to a method for machining workpiece circular arc radian, in particular to a grinding method for machining a large circular arc by the adoption of a molding grinder. The external diametral plane large arc grinding method comprises the steps that 1, firstly, a curved face grinding wheel is made, and modification is performed on the grinding wheel by the use of a grinding wheel dressing pen; the grinding wheel dressing pen and a center line of the grinding wheel form a certain angle; the angle is adapted to the large circular arc radian of a workpiece external diametral plane; 2, the grinding wheel is rotated, the dressing pen is kept still, and the grinding wheel is dressed into an inward concave curved face grinding wheel; an outer ring of a bearing is horizontally placed, and the center of the bearing is in the same horizontal line with the center of the curved face grinding wheel; the curved face grinding wheel is rotated, the workpiece is pushed forward to a target position, and then the workpiece is rotated. The external diametral plane large arc grinding method aims at solving the technical problem of achieving one-time molding large circular arc of the outer ring of the bearing on the molding grinder by the adoption of the curved face grinding wheel.

Description

technical field [0001] The invention relates to a method for processing the arc of a workpiece, in particular to a grinding method for processing a large arc with a forming grinder. [0002] The invention also relates to a method for processing curved grinding wheels. [0003] The invention also relates to a curved grinding wheel. Background technique [0004] In the prior art, centerless grinding machines are used to process the large arc of the outer ring of the roller, that is, through grinding. This kind of grinding machine has a relatively high degree of automation, but the price of the whole equipment is relatively high, and it needs to be adjusted according to different outer ring wheel profiles.

[0004] In the prior art, centerless grinding machines are used to process the large arc of the outer ring of the roller, that is, through grinding. This kind of grinding machine has a relatively high degree of automation, but the price of the whole equipment is relatively high, and it needs to be adjusted according to different outer ring wheel profiles. set again

Form grinding is generally not used to process the large arc of the outer ring, but mainly used to process the steps of the bearing. However, as a kind of grinding machine, the form grinding has its own advantages in processing, that is, it is simple and clear. ; But in the prior art, because the surface of the grinding wheel is flat, it is generally believed that there is no way to process the large arc of the outer ring; here is an explanation of where the grinding is; for bearings, it is necessary to grind There are many places, there are inner roads, two ends, and of course the surface of the outer ring. The large arc mentioned in this patent refers to the surface radian of the outer ring.
