Method and tool for installing and disassembling roller

Abstract

The invention relates to the field of technological equipment, and discloses a method and a tool for installing and disassembling a roller. The tool for installing and disassembling the roller comprises an opening dual ring pillow, wherein the opening dual ring pillow comprises a first ring body and a second ring body which are connected axially, notches are formed in the first ring body and the second ring body, and the inner diameter of the first ring body is greater than that of the second ring body. The method for installing and disassembling the roller comprises the following steps that opening dual ring pillow is axially attached to the roller or an inner expanding sleeve which is arranged on a shaft body in a sleeving mode, the one end, away from the roller, of the opening dual ringpillow is knocked axially, in this way, when installing is carried out, the second ring body can be used for abutting against the inner expanding sleeve, and the first ring body is knocked; and whendisassembling is carried out, the first ring body can be used for abutting against the roller, and the second ring body is knocked. The whole process of installing and disassembling is more convenientand concise, because of the indirect transmission force of the opening dual ring pillow, the knocking force can be uniformly transmitted to the roller or the inner expanding sleeve, so that the innerexpanding sleeve is not prone to being damaged in the process of installing and disassembling.

Description

technical field [0001] The invention relates to the field of process equipment, in particular to a roller loading and unloading method and tool. Background technique [0002] In the field of glass plate production, during the maintenance process of the grinder equipment, it is necessary to replace the rollers that transfer the glass plate in the input section. The method of replacing the roller is usually to remove the shaft first, remove the entire shaft and then remove the roller on the shaft. When removing the roller, first identify the direction of the expansion sleeve, and then tap the roller with a rubber head to make the roller move in the axial direction with a certain direction. The inner sleeve and the shaft are disengaged during the axial movement of the roller, which is actually the male of the inner expansion sleeve. The sleeve is disengaged from the female sleeve. Because the matching precision of the male sleeve and the female sleeve is very high, and the ma...

AI Technical Summary

Problems solved by technology

Because the matching precision of the male sleeve and the female sleeve is very high, and the material is relatively hard plastic, it will be damaged due to uneven force.

In the existing technology and process, in the process of installing or disassembling the roller, each person has different methods, different force levels, and occasional mistakes in the direction of knocking, resulting in a very high damage rate of the expansion sleeve inside the roller, with a damage rate of up to 30%. And the inner expansion sleeve cannot be repaired after damage
