Counter-force device for testing tension sensor

Abstract

The invention provides a counter-force device for testing a tension sensor. The counter-force device comprises an upper bracket and a lower bracket which are arranged in a staggered manner, the upper support comprises an upper support top plate, an upper support bottom plate, an upper support stand column, a lower ball cup and a lower ball. The two ends of the upper support stand column are fixedly connected to the upper support top plate and the upper support bottom plate respectively, the lower ball cup is arranged on the upper surface of the upper support bottom plate, and the lower ball is arranged in the lower ball cup. The lower support comprises a lower support top plate, a lower support bottom plate, a lower support stand column, an upper ball cup and an upper ball. The two ends of the lower support stand column are fixedly connected to the lower support top plate and the lower support bottom plate respectively, the upper ball cup is arranged on the lower surface of the lower support top plate, and the upper ball is arranged in the upper ball cup. After the tension sensor is fixed through the upper ball head and the lower ball head, pressing force applied to the top plate of the upper support can be converted into pulling force at the two ends of the tension sensor, it is guaranteed that the directions and the sizes of the force are consistent, and therefore testing of the tension sensor is achieved.

Description

【Technical field】 [0001] The invention relates to the field of testing devices for force values, in particular to a counter force device for testing tension sensors. 【Background technique】 [0002] The force standard machine can be divided into four categories according to its force generation principle: static weight force standard machine, lever force standard machine, hydraulic force standard machine, superimposed force standard machine. The force standard machine can generate standard force values ​​for testing and calibrating instruments such as force gauges or sensors. At present, most of the force standard machines with a large value range are compression-oriented, and cannot directly detect the tension sensor with a large value. However, the tension sensor with a high value is usually large in size, heavy in weight, and difficult to carry, which brings great difficulties to the detection of the sensor. And when some tension sensors with small force values ​​are tes...

Problems solved by technology

At present, most of the force standard machines with a large value range are compression-oriented, and cannot directly detect the tension sensor with a large value.

However, the tension sensor with a high value is usually large in size, heavy in weight, and difficult to carry, which brings great difficulties to the detection of the sensor.
