Invention content
The technical problem to be solved by the present invention is in current material tensile testing device, with the mill of jaw clamping device
The reliability of damage and clamping failure, clamping will reduce, and time-consuming and laborious in clamping process, reduce the efficiency of detection, wait for simultaneously
Test specimens are easy splashing clast after tension failure, there are security risk, and it is an object of the present invention to provide the drawing that material splashes can be avoided
Testing machine is stretched, the clamping of material can not only be fast implemented, avoids the abrasion between sample and clamps, improves and is stretching
Clamping reliability and tightness in detection experiment, improve the clamping efficiency in detection, while sample to be tested can be avoided to stretch
Clast splashes after fracture improve the safety used.
The present invention is achieved through the following technical solutions：
The cupping machine that material can be avoided to splash, including two structures are identical and the clamping piece of setting symmetrical above and below,
The clamping piece includes fixed block, and shielding cylinder is equipped between upper and lower two fixed blocks, and shielding cylinder is formed by two and half, and two and half
One end is hinged other end clamping between cylinder, is connected by more elastic strings between the upper and lower ends and fixed block of shielding cylinder, fixed
The putting groove of isosceles trapezoid is offered on the front of block, the long side of isosceles trapezoid putting groove is located at the top of short side, putting groove
Short side side fixed block front offers the sample break being vertically arranged, the bottom surface of the sample break perforation fixed block and with
Putting groove communicates, and the long side side fixed block front of putting groove, which offers, is vertically arranged hanging rod notch, and the perforation of hanging rod notch is fixed
The top surface of block is simultaneously communicated with putting groove, further includes the isosceles trapezoid rubber fixed frame for being fastened in putting groove, and rubber is fixed
The geomery of frame and the geomery of putting groove match, the bottom opening of rubber fixed frame, on the top plate of rubber fixed frame
It vertically is connected with hanging rod, hanging rod and rubber fixed frame can be caught in putting groove and hanging rod notch, and the top side wall of hanging rod is equipped with
