[0002] Coupling refers to the coupling of two shafts or shafts and rotary parts, which rotates together during the transmission of motion and power, and does not separate under normal circumstances. Sometimes it is used as a safety device to prevent the connected parts from bearing excessive load, and plays the role of overload protection. The design of the coupling fork head allows two shafts to be connected through a fork-shaped connecting part. This design allows a certain angular deviation and offset between the shafts. Traditionally, welding fixtures are required during the welding process of the universal coupling fork head and the spline sleeve or the connecting pipe.
[0003] The fixture used in the fork head welding process in the prior art needs to be manually aligned and welded after fixing the fork head and the spline sleeve. Manual calibration still causes deviation in the welding position of the fork head, which affects the use effect of the coupling. Moreover, the fork head welding fixture used in the prior art cannot be moved after fixing the fork head. The welder needs to constantly deflect the welding gun to complete the full-range welding of the fork head, and the weld of the fork head is prone to skew.
