Abstract

The invention relates to the technical field of physical performance detection, and relates to a tension and compression force application device, which comprises a bidirectional telescopic cylinder, a connecting assembly, a tension and compression force sensor, a first positioning piece and a second positioning piece, and is characterized in that the bidirectional telescopic cylinder comprises a shell and a moving piece, and the moving piece is suitable for switching between a tension force application position and a pressure force application position; the moving part comprises a first telescopic rod and a second telescopic rod which are oppositely arranged; the connecting assembly is suitable for being connected with a force-applied piece. The tension-compression type force sensor is connected between the second telescopic rod and the connecting assembly; the first positioning piece is connected to the first telescopic rod, and is limited at the first end of the shell at the pulling force application position so as to limit the first telescopic rod to extend out of the shell by a first length; the second positioning piece is connected to the second telescopic rod, and the second positioning piece is limited at the second end of the shell at the pressure application position so as to limit the second telescopic rod to extend out of the shell by a second length. The pulling and pressing force application device is simple in structure, low in cost and suitable for multi-point pulling and pressing force application occasions.

Description

technical field [0001] The invention relates to the technical field of physical performance detection, in particular to a tension-compression force application device. Background technique [0002] In the field of physical performance testing technology, it is very common to apply tension and pressure to the sample in a linear direction. In the related technology, the servo electric cylinder is used as the force application device, and the force sensor, high-speed force value acquisition and feedback electronic controller are used to realize the tension and pressure force application function, but the system structure is complex, the failure rate is high, the cost is high, and maintenance and The maintenance burden is heavy. Contents of the invention [0003] The invention provides a tension and pressure applying device, which is used to solve the defects of complex structure, high failure rate and high cost in the prior art. [0004] The present invention provides a ten...
