Description

Technical Field

[0001] The utility model belongs to the field of disassembly and assembly tools, and in particular relates to a self-lubricating bearing sleeve disassembly and assembly device. Background Art

[0002] The door module is an important part of the gate machine in the AFC system. The normal operation of the door module is an important guarantee for passengers to pass through the gate quickly and safely. With the continuous increase in operating time and passenger flow, the use time and frequency of the equipment module are also increasing. Some parts of the door module are prone to mechanical wear. For example, the main swing arm, auxiliary swing arm, and connecting rod self-lubricating composite bearing sleeve of the module's movable connection will directly affect the operating status of the door module after the wear reaches a certain degree. For example, problems such as door opening and closing jitter and abnormal noise will occur, which will directly affect the normal operation of the equipment and the operation service of the station. At present, according to the application conditions, most of the designs of the movable shaft connection parts of the door module are designed with self-lubricating composite bearing sleeves; the self-lubricating composite bearing sleeve is based on a steel plate, with spherical bronze powder sintered in the middle and a mixture of polytetrafluoroethylene (PTFE) and fiber rolled on the surface. The self-lubricating composite bearing sleeve is a kind of lossy part. After reaching a certain degree of wear, the use gap increases, which will affect the normal use of the equipment and usually require regular replacement of parts. Since the mounting holes of the door module components and the self-lubricating composite bearing sleeves are interference fits, coupled with the rust and stains after long-term use, the difficulty of disassembly and assembly of parts is increased. In the past, when disassembling and assembling parts, for the over-tightened door module components, it was necessary to use a large hammer to knock them out. This disassembly and assembly method would cause deformation and damage to the components. Since there is no corresponding disassembly and assembly device at present, for the over-tightened components, two people are required to cooperate with a hammer to knock them out. This method has poor installation accuracy, is time-consuming and labor-intensive, and has low maintenance efficiency. At the same time, using a large hammer to knock vigorously also has certain operational risks.
