In raw material metal is reviewed, even the material that some hardness are lower, as little forging, especially little annular element, according to the requirement of technical conditions, take tangential sampling, due to the restriction of the tangential size of testpieces, simultaneously again for ensureing the dimensional requirement being processed into the middle working portion of standard sample, the retained part length at sample two can only at about 10mm, and in order to increase the surface area of sawtooth clamping sample, reduce the load that sawtooth unit area is born, reach the effect that clamping is stable, the length of V-type sawtooth fixture block to sample holder part is at least 40mm, for the sample being shorter in length than 40mm, then can not clamp with V-type sawtooth fixture block.
Therefore, be necessary to work out a kind of Rockwell's hardness can measuring various metal material, the puller system of the sample of different length can be clamped again.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of electric power puller system modifying device, to overcome the strength degree that existing electronic tensile machine can not test the higher metal material of Rockwell's hardness and the deficiency that can not clamp shorter sample and exist.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of electronic tensile machine modifying device, comprise lower handle, lower clamp, lower clamping device, body, crossbeam, upper handle, upper fixture, upper clamping device and sample, lower handle is arranged on lower clamp; Upper handle is arranged on fixture; Crossbeam is arranged in body; Upper fixture is arranged on crossbeam; Lower clamp is arranged on the base plate of body; Lower clamping device is arranged in lower clamp; Upper clamping device is arranged in fixture, and described upper clamping device and lower gripping apparatus grips are at the connecting portion place of sample.
The similar bowl-type of shape of described lower clamping device and upper clamping device, be all made up of left fixture block, right fixture block and straight pin, left fixture block is connected by straight pin with right fixture block.
Described left fixture block and right fixture block are all by trapezium structure and inverted L-shaped Structure composing.
Described trapezium structure is provided with pin-and-hole.
