Abstract
The invention relates to a PCD controlled rubber high temperature fatigue crack testing machine. The testing machine comprises a high temperature chamber and a main unit; a motor is arranged in the host; an eccentric disc is connected to a V belt of an output shaft of the motor; the eccentric disc and a bottom end rail are connected by a connecting rod; a top end rail is arranged above the bottom end rail; a crossbeam is arranged above the top end rail; the crossbeams is arranged on fixing columns of the main unit; the front and the back of the top and the bottom end rails are provided with a plurality of clamp holders; and the position adjustment of the top end rail is realized by a top end rail lifting device arranged on the top of the crossbeam. The testing machine can be used for high temperature fatigue crack testing of samples at a temperature range from normal temperature to 150 DEG C. Characteristics of rubber fatigue can also be observed conveniently under static state conditions.
Description
Technical field
The present invention relates to a kind of test instrument, relate in particular to and be applicable under the hot conditions, rubber is carried out the testing machine of fatigue cracking test.
Background technology
The rubbery sample clamping is on entablature and sill, and entablature is driven to do by eccentric disc and pumps, and eccentric disc is driven by motor (frequency control, PLC and touch-screen control).
Existing rubber fatigue cracking tester, comprise main frame, motor is set in the main frame, two root posts are set on the described main frame, three crossbeams are set on the column, wherein be respectively equipped with clamper before and after entablature and the sill, sill connects eccentric disc by connecting rod, and eccentric disc is with the motor output shaft that is in transmission connection by V.Existing rubber fatigue cracking tester can not be finished and do fatigue cracking test, the various features that can not observe rubber fatigue under static condition under the hot conditions of regulation.During the clamping rubbery sample, need the eccentric disc in the hand rotation main frame, extremely inconvenient.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, provide a kind of and can under hot conditions, do experiment, have the PCD control rubber fatigue at high temperature cracking tester that hand, automatic function are integrated.
The object of the present invention is achieved like this: PCD control rubber high temperature fatigue testing machine comprises high-temperature cabinet part and main frame.Motor is set in the main frame, the motor below arranges the large V-belt wheel with transmission with its V, large V shape belt wheel is arranged on an end of bearing seat, the other end arranges eccentric disc, the eccentric disc connecting rod is set on the eccentric disc, the eccentric disc connecting rod is fixedly connected with traversing guide rod, and the upper end of traversing guide rod is fixedly connected with sill, the sill two ends by sliding sleeve be connected to be arranged on the main frame about two root posts; The sill top arranges entablature, and the entablature jacking gear is set in the middle of the entablature; Entablature arranges crossbeam, and the crossbeam two ends are fixedly connected with two root posts by nut; A plurality of clampers all are set, for the clamping rubbery sample before and after the upper and lower crossbeam.
High-temperature cabinet partly comprises support and control box.Observation lamp, heating apparatus, temperature measuring equipment and air-blast device are set in the case, can realize the control in room temperature to the 150 ℃ scope, control accuracy is ± 0.1 ℃.Air-blast device is used for balance the temperature inside the box.Casing is double-layer stainless steel, and the centre is provided with heat-insulation layer, on the positive door double glazing observation panel is set.
During test, the high-temperature cabinet casing is shifted onto on the support of back, sample is installed on the upper and lower clamper, regulate the optoelectronic switch position and make its registration coupon center, after regulating the stroke that needs as requested, shift again the high-temperature cabinet casing onto the main frame top, start instrument, arrange again temperature requiredly, set required parameter by man-machine interface.During equipment work, hand gear remains static, and does not affect normal running.
In order under static condition, to observe every fatigue characteristic of rubbery sample and to regulate easily the position of clamper, be provided with hand gear, and with unilateral bearing.
According to the above description, the present invention can do the fatigue at high temperature cracking test of sample in normal temperature to 150 ℃ scope.And can easily observe the various features of rubber fatigue under static condition.
