Elastic material repeated impact tester

Abstract

The invention relates to the field of test machines, and in particular relates to an elastic material repeated impact tester which is accurate in testing, saves cost and can accurately monitor and control an impact load in real time. The elastic material repeated impact tester comprises a machine body, a driving device, a transmission device, an eccentric device, a test device and a load adjusting device, wherein the machine body comprises a top plate arranged at the top of the machine body, a middle plate arranged at the middle part of the machine body and a bottom plate arranged at the bottom of the machine body, a test area is arranged between the middle plate and the bottom plate, the driving device is arranged on the middle plate and is in transmission connection with the transmission device arranged on the top plate, the transmission device is in transmission connection with the eccentric device which penetrates through the top plate and can extend to the test area, the eccentric device is connected with a test device arranged in the test area, the driving device drives the transmission device, the transmission device drives the eccentric device, so as to drive the test device to do vertical movement, and the test device is electrically connected with the load adjusting device arranged at the side edge of the machine body.

Description

technical field [0001] The invention relates to the field of elastic material testing machinery, in particular to an elastic material repeated impact tester. Background technique [0002] When the high polymer porous elastic material is repeatedly impacted under constant load, the hardness of the test object will change when the test object is repeatedly impacted for a long time, which will cause the impact load to attenuate. The existing domestic instruments usually use manual observation of the change of the impact load to test the equipment. Manually adjust the compression impact distance to meet the standard requirements of the impact load. The test results of this method are greatly affected by man-made, and the test has to be interrupted during manual adjustment. It is difficult to adjust successfully at one time. The test data is often due to the adjustment of the tester to manually adjust the size of the impact load. , the number of times deviates from the original d...
