Abstract

The invention relates to a device and method for depositing a modified coating on the surface of a ball, in particular to a device and method for depositing a modified coating on the surface of a precision ball. In the preparation technology of depositing the modified coating on the surface of the ball, a method of controlling a ball body to do intermittent random rotation is a main method for achieving the integrity of the coating deposited on the surface of the ball, the evenness of the coating deposited on the surface of the ball doing intermittent random rotation has certain deviation, and consequently the requirement for the precision of ultra-precision ball elements cannot be met. At least one set of three-phase channel is machined on the surface of a bottom disc in sequence from inside to outside in the radial direction of the bottom disc. The disc face of a middle-layer holder is sequentially provided with at least one limiting ring. Each limiting ring comprises a plurality of locating holes. Each locating hole is formed by three equal-size round holes in the manner that every two round holes are tangent. A drive ball is arranged in each round hole. Each through hole combination comprises a plurality of precision ball penetrating holes, and the precision ball penetrating holes in the through hole combinations and the locating holes are formed in a vertical one-to-one correspondence manner. The device and method are used for the process of depositing the modified coating on the surface of a precision ball element.

Description

technical field [0001] The invention relates to a device and method for depositing a modified coating on the surface of a precision ball, belonging to the field of surface engineering. Background technique [0002] Precision balls are important components in bearings, roundness meters, gyroscopes and precision measuring instruments. In order to improve their corrosion resistance and anti-friction and anti-wear properties, modified coatings are usually prepared on the surface of precision balls. At present, the preparation technologies of precision ball surface modification coatings mainly include physical bonding methods, physical transfer film formation methods, ion implantation and deposition methods, and so on. [0003] The physical transfer film forming technology is to make the coating material into powder or mass block, which will be mechanically squeezed and rubbed with the precision ball, so that the coating material will be transferred to the surface of the precisio...
