Immersed car hub steel ball cleaning system

Abstract

The invention relates to an immersed car hub steel ball cleaning system which mainly comprises an automatic cleaning device and a ball feeding mechanism arranged at the front end of the automatic cleaning device. The automatic cleaning device comprises a cleaning box used for storing a cleaning liquid; a nylon roller is arranged in the cleaning box; the front end of the roller tilts downwards; a spiral groove is arranged on the inner wall of the roller; through holes are distributed on the roller surface; the ball feeding mechanism comprises a ball storage box; a ball feeding channel is mounted at a ball outlet of the ball storage box; and a ball feeding brush is mounted on the ball feeding channel. When the roller rotates, the steel ball moves forwards along the spiral groove and sufficiently contacts with kerosene for cleaning in the forward-moving process. In the cleaning process, as the steel ball is immersed in the kerosene, an oil film protection layer is formed by the kerosene on the surface of the steel ball, and a good anti-impact effect is realized on the surface of the steel ball. The steel balls enter the roller through the ball feeding brush in turn and are not accumulated at the front section of the roller for sure, thereby improving the cleaning effect; and meanwhile, the friction frequency among the steel balls is lowered, and surface scratch is reduced.

Description

technical field [0001] The invention relates to a high-precision steel ball cleaning system, in particular to a steel ball cleaning system which is easy to use on the production site and has high cleaning effect. Background technique [0002] In the manufacturing process of steel balls, it needs to go through several major processes such as cold heading, light balls, heat treatment, hard grinding, preliminary grinding, strengthening, fine grinding and cleaning. After the primary grinding process, it is necessary to clean the surface of the steel ball to remove particles such as grinding slag and grinding liquid that adhere to the surface and affect the quality. At the same time, the appearance defects of the steel ball can be checked in time to prevent the grinding slag and grinding liquid from entering the downstream process. The traditional method is to send it to the cleaning workshop to use a sponge for manual cleaning or flushing in the cleaning oil tank. The labor i...

Problems solved by technology

But there are also disadvantages: when the steel ball moves in the horizontally placed drum, there are many frictions and impacts between the steel ball and the steel ball and between the steel ball and the inner wall of the drum, which can easily cause damage to the surface of the steel ball. It can be applied to the steel ball detection and cleaning after the light ball and between heat treatments, but it cannot be used in the steel ball cleaning after the preliminary research process

In addition, when feeding, a large number of steel balls enter from the feed inlet intermittently, which will easily cause congestion in the first half of the drum, which will have a certain impact on the cleaning quality, and the frequency of mutual friction between steel balls will also increase.
