To the customized cut-off of reinforcing bar in the engineerings such as road, power station, large-scale water conservancy.Bar cropper has weight compared with other cut-off equipments
Amount is light, energy consumption less, reliable operation, it is high-efficient the features such as, therefore be gradually machined in recent years with bar mill etc. extensively
Using played an important role in the every field of the development of the national economy.Existing cut-off equipment is related to again due to inside
Miscellaneous circuit devcie and control device leads to complicated integral structure inside equipment, expensive, and since cut-off equipment lacks
Suitable transmission mechanism, so that reinforcing steel bar cutting equipment is cumbersome, working efficiency is not high.
Summary of the invention
The purpose of the present invention is to provide a kind of structures simply, operation is convenient and what work efficiency is high is used for the convex of cutting machine
Take turns link mechanism.
To achieve the goals above, the invention provides the following technical scheme: being used for the cam link mechanism of cutting machine, including
Pedestal and the rack on pedestal, the rack are equipped with rocking bar and connect the cam of motor, and one end of the rocking bar is hinged
On the rack, the other end of rocking bar is equipped with idler wheel, and the outer surface of idler wheel and cam is affixed touching, and the idler wheel is hinged with by connecting rod
First lever, one end of the first lever are hinged with the second lever, and the other end of the first lever is hinged with third lever, the second lever
Hingedly on the rack, the second lever is equipped with arc convex, cross bar is hinged in rack, it is in hook-shaped clamping that cross bar, which is equipped with,
Portion, clamping portion are supported and are located on the arc convex of the second lever, and third lever is hinged with the shaft of fixed cutoff tool, and shaft is articulated with
In rack.
The principle of this programme is such that in use, the cam for connecting motor rotates under the drive of motor shaft, is hinged on
Rocking bar in rack is rotated around hinge, and rocking bar is equipped with idler wheel, and the outer surface of idler wheel and cam is affixed touching, so that cam is rotating
In the process, idler wheel can be driven to rotate, and then first lever hinged with idler wheel can be driven to deflect, due to the two of the first lever
End has been respectively articulated with the second lever and third lever, so that the second lever and third lever generate gearing, third lever is hinged with
The shaft of fixed cutoff tool, shaft rotation, and cutoff tool is driven to work, meanwhile, the second lever with arc convex connects
It is dynamic, it offsets in hook-shaped clamping portion with arc convex on hinged cross bar in rack, so that cross bar can be right when the second lever rotation
The deflection of second lever carries out stop, so that entire lever mechanism has corresponding supporting point, cam can just make shaft and cutoff tool
There is determining movement, when the hook portion of the cross bar is separated from the curved protrusion, cam dallies, and movement stops.
Preferably, the idler wheel uses the roller of ball shape, and idler wheel is preferably pasted with cam outer face and is touched, and is produced
Raw corresponding displacement.
Preferably, the connecting rod is articulated with the middle part of the first lever, so that when hinge rotation of the connecting rod on the first lever,
The deflection of the first lever can be made steady.
Preferably, the cutoff tool is disc, and the outside of cutoff tool is equipped with the shield being fixed on the rack, shield
Convenient for cutoff tool in cutting, it can prevent clast from disorderly flying, the effect played protection operator and keep working environment clean and tidy.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the present invention for the cam link mechanism embodiment of cutting machine.
