Lotus ability.Because the resistance to shock loads ability in the prior art not dedicated for detection worm and gear and rack-and-pinion is set
It is standby, the ability of its resistance to shock loads is typically judged using the material property of worm and gear and rack-and-pinion in the prior art, though
Use requirement so can be reached to a certain extent, but still suffers from the problem of decision errors are big.
The content of the invention
In view of this, the purpose of this utility model is to provide a kind of Charpy platform, can effective detection workpiece it is anti-
Shock loading ability.
To reach above-mentioned purpose, the utility model provides following technical scheme：
A kind of Charpy platform, including bottom plate, the bottom plate are provided with two root posts, and the top of two columns is right
It should be provided between bearing block, the bearing block and be provided with rotating shaft, set, which is equiped with to install in swing arm, the swing arm, in the rotating shaft is provided with
Jump bit.
Further, the center of the jump bit is raised provided with impact.
Further, wherein a column is provided with fan dial, the fan dial and the rotating shaft are coaxial,
And the fan dial is provided with the indicating graduation for being used for showing impulse force magnitude of load.
Further, the swing arm is provided with the reading mark being correspondingly arranged with the indicating graduation.
Further, web beam is provided between two columns.
Further, the jump bit is removably mounted in the swing arm.
Further, the swing arm and the rotating shaft synchronous axial system.
Further, in addition to quantitative testing fatigue mechanism, the quantitative testing fatigue mechanism includes active driving lever and suit
It is arranged on annular on the driven sheave in the rotating shaft, the driven sheave and is laid with radial slot, the active driving lever and sets
There is the shifting block coordinated with the radial slot, and the column is provided with the motor for being used for driving the active driving lever uniform rotation.
The beneficial effects of the utility model are：
Charpy platform of the present utility model, using swing arm and the movement of falling object of jump bit, is acted on workpiece
Resistance to shock loads experiment directly can be carried out to workpiece, by adjusting the height of jump bit, the size of conveniently adjusted shock loading,
In this way, the resistance to shock loads ability of workpiece can be detected easily, Detection results are more accurate.
By setting quantitative testing fatigue mechanism, do interval using the driving lever fluctuation driven sheave of uniform rotation and quantitatively turn
It is dynamic, it can effectively drive swing arm to be rotated according to fixed angle, realize the technique effect to the fatigue impact of workpiece, you can realize
The technical purpose of the quantitative tired resistance to shock loads experiment of workpiece.
