Method for machining stirrer shaft end part sealing ring B

Abstract

The invention discloses a method for machining a stirrer shaft end part sealing ring B, and belongs to the field of shaft end part machining. The method comprises the following steps of 1 first installing hole machining and 2 second installing hole machining. The first installing hole machining step comprises the substeps that 1 assembling is conducted, wherein the position of the to-be-machined first installing hole is perpendicular to a horizontal plane, and a third guide hole is formed to be located over the machining position of the to-be-machined first installing hole; 2 hole machining isconducted; and 3 the to-be-machined shaft end part sealing ring B is rotated by 180 degrees around the center and then reassembled to a machining tool provided with the third guide hole for hole machining. The second installing hole machining step comprises the substeps of 1 assembling, wherein the position of each to-be-machined second installing hole is perpendicular to the horizontal plane, and a first guide hole and a second guide hole are formed to be respectively located over the machining positions of the two to-be-machined second installing holes; and 2 hole machining. According to the method for machining the stirrer shaft end part sealing ring B, the to-be-machined installing holes of the shaft end part sealing ring B can be made to be located perpendicular to the positions of the horizontal plane through assembling, the guide holes are arranged so that a drill bit can rapidly and accurately position the positions of the to-be-machined installing holes, lining marking is notneeded, the machining efficiency is improved, and the machining precision is high.

Description

technical field [0001] The invention belongs to the field of shaft end piece processing, and more specifically relates to a method for processing a seal B ring of a shaft end piece of an agitator. Background technique [0002] Twin-shaft mixer is a commonly used equipment in the field of construction. It is used for mixing various powdery materials. During the use of the mixer, the drive shaft is installed inside and outside the equipment, and there is an assembly gap between it and the fixing parts. The material in the mixer Materials such as slurry will leak out through this gap, which will affect the normal use of the mixing equipment. Therefore, shaft end seals are usually required to seal the shaft end assembly gap to prevent leakage. [0003] The shaft end seal B ring is a component of the shaft end seal kit used in twin-shaft mixers. It is an industry standard part, and its shape and structure are as follows: figure 1 , figure 2 , image 3 and Figure 4 As shown,...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem of low processing efficiency and poor accuracy of the installation hole of the shaft end seal B ring in the prior art, the present invention provides a processing method for the shaft end seal B ring of the mixer. Through assembly, the shaft end seal B ring is processed and installed The hole is located perpendicular to the horizontal plane. By setting the guide hole, the drill bit can quickly and accurately locate the position of the installation hole to be processed, without marking, improving the processing efficiency and high processing accuracy.
