Anti-leakage structure and method of shot blasting machine

Abstract

The invention discloses an anti-leakage structure and method of a shot blasting machine. The anti-leakage structure of the shot blasting machine is characterized by comprising a bearing end cover, a bearing and a bearing seat which are arranged along a shaft, wherein the bearing is arranged in the bearing end cover and the bearing seat; a wind inlet channel is formed in the upper end of the innerside of the bearing end cover; and a shot returning outlet is formed in the lower end of the inner side of the end cover. According to the anti-leakage structure of the shot blasting machine, high-pressure wind is blown from outside to inside and passes through a gap between the inner ring and the outer ring of the bearing, thus a high-pressure wind curtain is formed on the inner side of the bearing to prevent shot and dust from flying into the bearing, and even if a small amount of dust flies into the bearing, the small amount of dust can be blown out of the bearing by the high-pressure wind.The wind inlet channel is formed in the upper end of the inner side of the bearing end cover, and the shot returning outlet is formed in the lower end of the inner side of the end cover, so that theshot and the dust fall into a shot collecting channel in a chamber body.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an anti-leakage structure and method for a shot blasting machine. Background technique [0002] The working principle of the shot blasting machine is to use high-speed steel shots to hit the workpiece to achieve the purpose of cleaning the surface and strengthening the surface, but it is inevitable to hit the body and related transmission components while hitting the workpiece, and in addition to factors such as impact reflection with the workpiece, the steel The pellets are easy to flow out of the chamber through the shaft hole, and it is also easy to hit the bearing. The problems that are likely to occur in the prior art are: the bearing is easy to wear; the pellets and dust leak out; and the bearing is noisy due to foreign matter. Need to invent a kind of new structure for actively preventing steel shot from impacting bearing. Contents of the invention [0003] The pur...
