Intelligent and rapid installation equipment for high-temperature bearing inner rings of roller cage shoe and normal-temperature middle shaft of roller cage shoe

Abstract

The invention belongs to the technical field of mining machinery equipment manufacturing, and relates to intelligent and rapid installation equipment for high-temperature bearing inner rings of a roller cage shoe and a normal-temperature middle shaft of the roller cage shoe. The bearing inner rings are put in from a feed inlet, the bearing inner rings slide down on lower supporting inclined surface of a bearing inner ring slide way, and the bearing inner ring at the lowermost slides to an opening of the lower end of the bearing inner ring slide way, is blocked by a stop block at the tail end of the bearing inner ring slide way, is positioned and is completely immersed in transformer oil to be heated to 80-100 DEG C. A six-axis robot drives a manipulator, and a first finger and a second finger are immersed under the liquid level of the transformer oil to hold the bearing inner rings tightly, The six-axis robot drives the manipulator, so that the bearing inner rings quickly sleeve mounting sections of the bearing inner rings. According to the intelligent and rapid installation equipment for the high-temperature bearing inner rings of the roller cage shoe and the normal-temperature middle shaft of the roller cage shoe, the intelligent and automatic machining level is improved, the working efficiency is improved, the labor intensity of workers is greatly reduced, the interference amount of assembling is increased, the mounting firmness is improved, the surface scratch of the middle shaft of a roller is avoided, the quality of the roller cage shoe is improved, and the safety ofthe roller cage shoe is improved.

Description

technical field [0001] The invention belongs to the technical field of mining machinery and equipment manufacturing, and relates to installation equipment for roller lugs used in mine hoisting equipment, in particular to intelligent rapid installation equipment for high-temperature bearing inner rings and normal-temperature central shafts for roller lugs. Background technique [0002] Roller lugs are used as guide wheels when cages, skips or counterweights are raised and lowered along the steel tank road. They are installed above and below the lifting container. The rubber wheels of multiple roller lugs hold the steel tank road tightly to guide and buffer The function is to lift a very important part on the container. The roller can ear includes the roller assembly, the roller assembly includes the roller center shaft, two tapered roller bearings, the bearing cover and the hub, the tapered roller bearing includes the separable bearing inner ring, the bearing outer ring and t...

AI Technical Summary

Problems solved by technology

[0003] Manually assembled bearing inner ring and roller center shaft, due to limited human strength, only a small amount of interference can be used between the bearing inner ring and the roller center shaft, problems often occur during use, the two become loose, or the installation The position is not correct, the tapered roller bearing is damaged in advance, and the anti-repair rate of the roller tank lug is high. If it is not rectified in time, the company will lose many customers, which will lead to huge losses for the company

[0004] In order to meet the needs of the market, the interference between the inner ring of the bearing and the middle shaft of the roller has to be increased, and the tolerance used is H7 / n7. If such a tolerance is completely assembled by manual force, the production efficiency will be greatly reduced, and the difference between the two Mutual friction will also scratch the surface of the roller shaft, which will bring unnecessary safety hazards. It is necessary to change the assembly process and configure new assembly equipment
