Description

Technical Field

[0001] The invention relates to a coupling and processing equipment thereof, and in particular to a coupling processing positioning mechanism and a coupling with a multi-directional communication structure. Background Art

[0002] In the processing of a coupling, a positioning mechanism is required to clamp and position it, so as to facilitate various processing. Patent document CN211466109U discloses a positioning mechanism group, including a plurality of first positioning mechanisms, a plurality of second positioning mechanisms and a plurality of third positioning mechanisms, each positioning mechanism in the fixture group includes a main body with a clamping end, wherein at least two main bodies of the positioning mechanisms are on the same side of the clamping end and the clamping ends are arranged adjacently in the same direction or at least two main bodies of the positioning mechanisms are on the opposite sides of the clamping end and the clamping ends are arranged oppositely, the positioning mechanism is a first positioning mechanism or a second positioning mechanism or a third positioning mechanism, the clamping ends of the first positioning mechanism and the second positioning mechanism have lateral mobility for providing lateral clamping force, the clamping end of the third positioning mechanism has vertical mobility for providing vertical clamping force, which provides clamping capabilities at multiple angles and directions, so that the workpiece has good stability during machining. However, when this positioning mechanism group adopts a hydraulic drive structure, the multiple positioning mechanisms set therein need to use an external pipeline structure to supply hydraulic oil to them, making the pipeline structure of the positioning mechanism group extremely complex and exposed to the outside of the equipment. The exposed pipeline is more likely to interfere with other equipment or pipelines, bringing additional external forces to the pipeline, which can easily cause pipeline instability, leakage, vibration and other problems. When the hydraulic oil flows through the pipeline, it will cause pressure loss along the way and local pressure loss. At the same time, the vibration of the equipment will cause pipeline vibration, and the exposed pipeline lacks sufficient support and protection, which will aggravate this problem.
