Problems solved by technology

[0002] At present, the main shaft of the power head of the machine tool that adopts the wet processing method generally adopts two waterproof structures. One is to install a water-repelling device on the main shaft and the flange. This structure is not completely waterproof and causes the main shaft bearing to rust. The other is to install a waterproof seal This method can have a better waterproof effect, but when the power head has a high speed, it will cause the sealing ring to heat up and wear out. Both structures are unreliable, which can easily lead to damage to the main shaft and reduce the service life of the equipment.

Abstract

The invention relates to mechanical manufacturing industries, in particular to a spindle waterproof mechanism which particularly comprises a spindle, a flange cover, a flange disc, a joint, an air pipe, an outer spacing sleeve, an inner spacing sleeve, a sealing ring, an adjusting pad and a box. The adjusting pad presses a bearing outer ring, the inner spacing sleeve presses a bearing inner ring, the flange disc presses the outer spacing sleeve and is connected with the box, the air pipe is connected with the joint to be mounted on an air hole of the flange disc, the sealing ring is mounted in an annular groove of the flange disc, a shaft neck of the spindle presses the inner spacing sleeve, and the flange cover is connected with the flange disc. Compared with the prior art, the spindle waterproof mechanism has the advantages of reliable structure, low temperature increase and complete water proofing, water can be effectively prevented from entering the spindle, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the machinery manufacturing industry, in particular to a main shaft waterproof mechanism. Background technique [0002] At present, the main shaft of the power head of the machine tool that adopts the wet processing method generally adopts two waterproof structures, one is to install a water throwing device on the main shaft and the flange, this structure is not completely waterproof, which leads to the rust of the main shaft bearing, and the other is to install a waterproof seal This method can have a better waterproof effect, but when the power head has a high speed, it will cause the sealing ring to heat up and wear out. Both structures are unreliable, which can easily lead to damage to the main shaft and reduce the service life of the equipment. . Contents of the invention [0003] The purpose of the present invention is to provide a main shaft waterproof mechanism, which is completely waterproof, has low temperature ris...
