Abstract

The invention discloses a crankshaft flange coupling device. The device comprises a rotating arm frame assembly and a rotary power set, wherein the rotating arm frame assembly comprises a rotating armand connecting bolts, symmetrical cross grooves are formed in the upper portion and the lower portion of the rotating arm correspondingly, a bolt head is arranged on the left side of the center position of the rotating arm, a detachable circular positioning head is arranged on the right side of the center position of the rotating arm, hand wheels are arranged in the middle of the connecting bolts, connecting threads are arranged on the right portion of the connecting bolts, the connecting bolts are matched with the cross grooves correspondingly, and the rotary power set is matched with the bolt head. According to the crankshaft flange coupling device, the difficult problems of large manpower and low efficiency caused by the fact that when the engine is assembled, the crankshaft is rotatedto cause damage to screw holes of the crankshaft flange and one person cannot rotate the crankshaft to assemble the engine are solved.

Description

technical field [0001] The invention relates to the field of assembly technology, in particular to a crankshaft large end coupling device. Background technique [0002] During the engine assembly process, the engine crankshaft is continuously rotated for assembly and inspection of the internal parts of the engine, so a transitional device is needed to connect with the screw hole of the crankshaft flange (crankshaft big end). At present, when rotating the engine crankshaft, all The two bolts are directly inserted into the screw holes of the crankshaft flange to achieve rotation while applying torque, which will cause damage to the screw holes of the crankshaft flange and affect the quality of the engine. Rotating the crankshaft to assemble the engine causes the problems of large manpower and low efficiency. [0003] The disclosure of the above background technical content is only used to assist in understanding the inventive concepts and technical solutions of the present in...
