A device for detecting the strength of a limit block with a super shock-absorbing function

Abstract

The invention discloses a device for detecting the strength of a limit block with a super shock-absorbing function, which comprises a workbench and supporting legs. The bottom of the workbench is equidistantly fixed with a plurality of support legs, and one side of the workbench is provided with a fixing mechanism. , and there is a fatigue test mechanism on the top of the workbench. This super shock-absorbing function limit block strength detection device is different from the existing technology. Before each use, the performance of the S-type tension pressure sensor is first tested, and the standard value Comparison, to ensure the mastery of the performance of the S-type tension pressure sensor. On the other hand, when the tensile performance of the rope deviates, the tension generated by the rope will be deviated within the same displacement of the limit block to be detected. Before each use, the tensile performance of the rope is detected by the tension detection mechanism. By comparing the standard value, and at the same time, the compensator is set at the terminal to compensate the performance of the S-type tension pressure sensor and the tension of the rope to ensure the accuracy and accuracy of the detection data. Intuitive.

Description

technical field [0001] The invention relates to the technical field of limit block detection, in particular to a limit block strength detection device with super shock absorption function. Background technique [0002] When testing the strength of the automobile shock absorbing limit block, a fatigue testing machine is often used to detect the performance of its anti-extrusion strength. In the prior art, when the limit block is tested for fatigue strength, its The force sensor is also doing fatigue tests following the limit block at the same time, which greatly affects the life of the force sensor and is easily damaged. There is a patent document with patent number CN201210011484.0, which uses a tension sensor instead of an ordinary force sensor. The tension sensor passes Detect the tension of the rope, so as to know the pulling force acting on the tested piece, so as to control the fatigue of the sensor.

[0002] When testing the strength of the automobile shock absorbing limit block, a fatigue testing machine is often used to detect the performance of its anti-extrusion strength. In the prior art, when the limit block is tested for fatigue strength, its The force sensor is also doing fatigue tests following the limit block at the same time, which greatly affects the life of the force sensor and is easily damaged. There is a patent document with patent number CN201210011484.0, which uses a tension sensor instead of an ordinary force sensor. The tension sensor passes Detect the tension of the rope, so as to know the pulling force acting on the tested part, so as to control the fatigue of the sensor

[0003] However, after long-term use, the continuous reciprocating motion of the test piece causes the rope to be pulled repeatedly, which easily leads to an increase in the fatigue of the rope, resulting in different tensions generated by the rope at the same displacement, and its existing device cannot guarantee Effectively and intuitively understand the impact of different rope tensions. At the same time, the way of using the rope to cooperate with the tension sensor only reduces the fatigue of the sensor. Long-term use will still have a certain impact on its performance. If the staff does not understand the tension deviation of the rope and cannot guarantee the detection accuracy of the tension sensor before use, it will easily affect the accuracy of the normal strength detection of the limit block, and cannot guarantee the accuracy of the strength detection of the limit block. To this end, we propose a device for detecting the strength of the limit block with super shock absorption function
