Abstract

The invention discloses a flexible fixture for coating a bearing roller. The flexible fixture for coating the bearing roller comprises an upper circular disc, a lower circular disc, and a plurality ofbearing roller support bars. The upper circular disc and the lower circular disc are connected through multiple double-end studs; a plurality of inserting holes are formed in outer side faces of theupper circular disc and the lower circular disc; the bearing roller support bars are sleeved in the inserting holes; a positioning sleeve is arranged on the lower part of the lower circular disc; anda connecting part matched with a furnace cavity is arranged on the positioning sleeve. According to the flexible fixture for coating the bearing roller provided by the invention, a distance between the upper circular disc and the lower circular disc is adjustable, and the lengths of the bearing roller support bars are adjustable, so that the requirements on coating and clamping the multiple typesof bearing roller support bars can be met, the coating quality is ensured, and meanwhile, the production efficiency is improved.

Description

technical field [0001] The invention relates to a disc-type clamp, in particular to a flexible clamp for coating a rolling body of a bearing. Background technique [0002] With the advancement of bearing manufacturing technology and the improvement of user demand, people have put forward higher requirements for the life and self-lubricating performance of bearings. Traditional bearings are lubricated with lubricating oil or grease, which not only wastes costs, but also causes certain pollution to the environment, which is not suitable for the current development direction of green manufacturing. The physical vapor deposition technology is a green and non-polluting surface modification technology, which has been greatly developed in recent years and has been widely used in aerospace, automobile manufacturing, molds, cutting tools, bearings and other fields. For bearings, the rolling elements are treated with low-temperature coating, which can not only reduce surface friction...
