Abstract
The invention discloses a cylindrical test sample crushing tool. The cylindrical test sample crushing tool comprises an upper supporting plate, a lower supporting plate, tightening nuts, fixing pins, a rubber band and a test sample, wherein the test sample is clamped between the upper supporting plate and the lower supporting plate; after the rubber band penetrates through a central hole of the test sample, two ends of the rubber band are tied on the fixing pin; and end faces of the upper supporting plate and the lower supporting plate are relatively upward and are located on the same central line. Bearing shafts are mounted at the centers of the back surfaces of the upper supporting plate and the lower supporting plate; the tightening nuts are arranged on the bearing shafts; and the upper supporting plate and the lower supporting plate are fixed on a testing machine through the tightening nuts. The fixing pins are mounted on the outer diameters of the two sides of the lower supporting plate. The cylindrical test sample crushing tool has the advantages that the cylindrical test sample crushing tool can accurately guarantee that a test force rightly passes through a curve of the test sample and the accuracy of a test result is guaranteed. The cylindrical test sample crushing tool has low cost and is convenient to use.
Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of cylindrical shape sample conquassation frock.
Background technology
It is carry out between two flat boards of testing machine that the crushing strength of cylindrical shape sample detects, and does not have positioning function, can only with the naked eye locate between flat board.In order to ensure the accurate of assay, sample must in the middle of two clamping plate, the axis of sample and platen parallel, and the test force of testing machine is just by the axis of sample.Some powder metallurgy cylindrical shape samples are compressing by dusty material by pressing machine, and some press tonnage is little, and intensity may be not enough, needs the detection carrying out crushing strength.The crushing device of testing machine is upper and lower two fixation device, when carrying out crushing test to some cylindrical samples, if cylindrical sample is placed directly on lower supporting plate, at this moment because conquassation sample is cylindrical, be easy to roll on lower supporting plate, the test force being difficult to warranty test machine is just in time pressed on the axis of circular specimen, causes the inaccurate of test findings.
Summary of the invention
One is the object of the present invention is to provide to be placed between upper and lower two back up pads of testing machine crushing device by some cylindrical shape samples, load is detected when the axis of sample and the conquassation of back up pad parallel boot are broken, reach accurately, fast, simple operations, efficiency is high, the simple a kind of cylindrical shape sample conquassation frock of structure.
Technical solution of the present invention is sample, a kind of cylindrical shape sample conquassation frock, comprise upper backup pad, lower supporting plate, fastening nut, fixed pin, bungee, sample, it is characterized in that accompanying sample (6) between upper backup pad (1) and lower supporting plate (2), bungee (5) fastens tight in fixed pin (4) through bungee (5) two ends after sample (6) center pit, on upper backup pad (1) is relative with the end face of lower supporting plate (2), and on concentricity line.
The center, the back side of upper backup pad (1), lower supporting plate (2) is provided with bolster, bolster has fastening nut (3), by fastening nut (3), upper backup pad (1), lower supporting plate (2) is fixed on testing machine.
Sample (6) is hollow tubular.
Fixed pin (4) is arranged on the external diameter of lower supporting plate (2) both sides.
Compared with prior art, advantage of the present invention is:
1, accurately warranty test power just by the axis of sample, the correctness of test findings can be ensure that.
2, cost is low, easy to use.
accompanying drawing illustrates:
Fig. 1 is fagging assembling using state schematic diagram under upper fagging of the present invention.
Fig. 2 is that lower supporting plate of the present invention installs sample assembling schematic diagram.
Fig. 3 is upper backup pad structural representation of the present invention.
Fig. 4 is lower supporting plate structural representation of the present invention.
Reference numeral: upper backup pad (1), lower supporting plate (2), fastening nut (3), fixed pin (4), bungee (5), sample (6).
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
