Abstract
The utility model discloses a crank assembling structure, which comprises a crank and a main shaft, wherein a main shaft mounting hole is formed in the crank; the main shaft is arranged in the main shaft mounting hole; a crank connecting hole is formed in the bottom of the crank; the crank connecting hole is a screwed hole; and a connecting gap is arranged between the crank connecting hole and the main shaft mounting hole. According to the crank assembling structure disclosed by the utility model, the crank assembling technology and tools are simpler, more reliable and efficient, and the cost is low.
Description
Technical field
The utility model relates to a kind of crank assembly structure.
Background technique
In stone cutting equipment, marble gang saw and granite sand saw is widely used at stone material circle because of having advantages such as high efficiency to processing stone material sheet material, low cost.The working principle of marble gang saw and granite sand saw can simply be described below: big flywheel drives the crank rotation, the crank drive link, and connecting rod drive saw frame is reciprocating, and saw blade is contained on the saw frame, and saw blade cuts stone material with saw frame is reciprocating.Crank is as key component in marble gang saw and granite sand saw equipment; Its assembly technology is particularly important; Those of skill in the art constantly explore for the assembly technology of crank, and are a kind of with low cost for seeking, assembly technique simple and reliable for structure and effort.
In the prior art, the mode of the mounting process of crank employing has:
Hot charge practice----the tolerance that the crank heating makes its mounting hole change reach configuration requirement is greatly just installed with main shaft; But the frock of the heating that this technology is required is bigger; It is longer to heat the required time, in assembly process, wants seeking time shorter, in case the crank temperature descends; The crank installation process can not be adjusted, and at this moment deal with cumbersome.
Cold charge---the method is with the main shaft cooling, makes main shaft reach the required requirement of process Installation, just crank is installed on the main shaft, and the method is the same with hot charge practice, can the nonadjustable phenomenon of crank possibly occur.
Wedge shape spreading method---the method is in the fluting with chock wedging crank, makes crank mounting hole spreading, reaches the tolerance of assembly technology, can adjust during this method mounting crank, but after being in place, chock takes out difficult.
The model utility content
The utility model technical issues that need to address just are to overcome the defective of existing technology, and a kind of crank assembly structure is provided, and it makes crank assembly technology and frock simpler, reliable, efficient, with low cost.
For addressing the above problem, the utility model adopts following technological scheme:
The utility model provides a kind of crank assembly structure; Comprise crank and main shaft; Said crank is provided with spindle mounting hole, and said main shaft is installed in the spindle mounting hole, and said crank bottom is provided with the crank attachment hole; Said crank attachment hole is a tapped hole, is provided with one between said crank attachment hole and the said spindle mounting hole and connects the space.
Said crank attachment hole is the Full Thread FT through hole.
Perhaps, said crank attachment hole is the partial thread through hole.
The utility model makes crank assembly technology and frock simpler, reliable, efficient, with low cost.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the side view of Fig. 1.
Embodiment
Like Fig. 1, shown in Figure 2; The utility model provides a kind of crank assembly structure, comprises crank 1 and main shaft 2, and said crank is provided with spindle mounting hole; Said main shaft is installed in the spindle mounting hole; Said crank bottom is provided with crank attachment hole 3, and said crank attachment hole is a tapped hole, can be Full Thread FT through hole or partial thread through hole; Be provided with one between said crank attachment hole and the said spindle mounting hole and connect space 4.
The assembly process of the utility model is: the crank attachment hole is a screw thread, and this hole can be the Full Thread FT through hole, also partial thread through hole.Screw in the crank attachment hole with two bolts 5, a steel ball 6 is arranged between two relative bolts.When bolt inwardly screws in attachment hole; Two bolts all withstand steel ball 6; When inwardly screwing in, the reaction force of the screw thread in bolt and the crank attachment hole rises by the space that is connected between crank attachment hole and the spindle mounting hole greatly, thereby the crank mounting hole is risen greatly again; Make the crank mounting hole reach the assembly technology requirement, at this moment can easily crank be installed to main shaft and get on.When crank install adjust to the right place after, bolt outwards screws out, at this moment the crank mounting hole shrinks under the resiliently deformable of self main shaft is held tightly, removal bolt and steel ball are fastened to crank on the main shaft with regard to the connecting bolt of available crank.
The utility model technology is simple, reliable, efficient, with low cost.
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (3)
1. crank assembly structure; It is characterized in that: comprise crank and main shaft; Said crank is provided with spindle mounting hole, and said main shaft is installed in the spindle mounting hole, and said crank bottom is provided with the crank attachment hole; Said crank attachment hole is a tapped hole, is provided with one between said crank attachment hole and the said spindle mounting hole and connects the space.
2. crank assembly structure as claimed in claim 1 is characterized in that: said crank attachment hole is the Full Thread FT through hole.
3. crank assembly structure as claimed in claim 1 is characterized in that: said crank attachment hole is the partial thread through hole.
