Description

Technical Field

[0001] The utility model belongs to the field of joint disassembly and assembly, and in particular relates to a disassembly device for a quick joint. Background Art

[0002] Quick connector is a kind of connector that can connect or disconnect pipes without tools. It is mainly used in hydraulic system connections. It is more and more widely used in hydraulic systems because of its advantages such as easy installation, convenient maintenance, cost saving and environmental protection.

[0003] At present, the assembly of quick connectors is all automated / semi-automated production line assembly, and is fixed at the connection point by thread glue. After assembly, if market reasons / quality reasons arise and need to be disassembled for modification / quality analysis, one end of the quick connector is usually fixed by a fixing fixture, and the other end of the quick connector is clamped by an electric tightening device for rotational disassembly. During disassembly, the existing electric tightening device has insufficient torque, which affects the disassembly effect; and manual operation is required to fix and clamp the quick connector, which is cumbersome.

[0004] Therefore, it is necessary to provide a disassembly device for a quick connector. Utility Model Content

The clamping sleeve is driven to rotate by a hydraulic motor to achieve large torque output and improve the disassembly effect. BRIEF DESCRIPTION OF THE DRAWINGS
