Problems solved by technology
[0007] The purpose of the present invention is to solve the problem that the original trimming method is time-consuming, labor-intensive, and has no reliable guarantee for machining accuracy, and the problem that the radius of the trimming oilstone is not close to the radius of the channel or the length of grinding and combining time is unclear. The number of waste products and the difficult problem of reducing production efficiency, the present invention proposes an oil stone dressing device and a dressing method for fine grinding grooves of ball bearings

The invention belongs to the field of ball bearing lapping channel trimming, particularly relates to an oilstone trimming device and method for a ball bearing lapping channel, and aims to solve the problems that an original trimming way is time-consuming and labor-consuming, does not reliably guarantee machining precision, a certain number of waste products are generated, and production efficiencyis reduced as the radius of a trimming oilstone is not close to that of the channel, or the lapping-in time is not clear; a circular disc base of a tool is clamped through a three-jaw indexing plateof a horizontal rectangular table surface grinding machine, the oilstone is placed above the circular disc base, and the circular disc surface is marked with size scales; according to the size of theradius of a workpiece channel, extending length of the oilstone is adjusted according to scales, a needed oilstone shape is trimmed by rotating the indexing plate and feeding a machine tool, so that machining time of the trimming way is remarkably shortened, time for manually trimming the oilstone and time for lapping the oilstone are saved, machining precision meets the technological requirements, and meanwhile for the improved trimming mode, stability is good, machining precision is high, and machining efficiency is greatly improved.
Description
technical field [0001] The invention belongs to the field of ball bearing finishing groove repairing, and in particular relates to an oilstone finishing device and a finishing method for ball bearing finishing grooves. Background technique [0002] Deep groove ball bearings consist of an outer ring, an inner ring, a set of steel balls and a cage. When working, it mainly bears radial loads, and can also bear axial and radial loads at the same time. It is widely used in machinery and electrical industries. Its structure is shown in figure 1 . [0003] Double-half inner ring ball bearings are used to bear radial load and axial load at the same time, and can work at higher speeds. This kind of bearings are selected and combined by the manufacturer according to certain preload requirements. After the bearing is installed and fixed, the clearance in the bearing is completely eliminated, the ring and the steel ball are in a pre-tightened state, and the rigidity of the combined be...
