Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with specific implementation
Example and attached drawing are described in detail.
The crank assembly method of existing flying crank shears mainly includes two kinds, is groove method and key positioning mode respectively.Crank
Assembly groove method: by manually on crank parts and cutting on axis part groove respectively and setting benchmark, after will in assembling process
The alignment of two grooves, realizes the assembly of crank.Crank fitted key positioning mode: by crank and the side for cutting processing positioning spline on axis
Method sets keyway benchmark in the fabrication process, then positions the assembly for realizing crank according to keyway in assembling process.
There are the following problems for the crank assembly groove method of existing flying crank shears: first, components need after manufacture
To carry out groove in designated position, either artificial groove or unartificial groove, scribe line position with the assembly of part itself
There are large errors for base position；Second, crank must be assembled strictly according to its benchmark with the assembly for cutting axis, in big magnitude of interference
Under the premise of, also to guarantee that groove is aligned, which adds assembly difficulty.Therefore, crank with cut in axis assembling process, substantially
(the upper small axis center of lower crank is on shear centre line) in place can not be once assembled, also needs to adjust later (by two grooves pair
Together), this had both increased assembly difficulty and has also increased assembly risk.
There are the following problems for the crank fitted key positioning mode of existing flying crank shears: first, components are in the fabrication process
Need to process positioning spline, the processing needs of positioning spline are very accurate, and this adds increased the processing costs of components；Second, every
The keyway precision of a part processing is different, this just makes interchangeability of parts poor.
In conclusion the crank assembly groove method and crank fitted key positioning mode using flying crank shears are not easy to guarantee
Assembly precision.
Based on the above issues, the embodiment of the invention provides a kind of crank positioning devices, solve existing flying crank shears machine
The problem that middle crank and the assembly difficulty of flying shear are big and assembly precision is low.
