Buffering and energy-absorbing type counter-force device for testing tension sensor

The utility model provides a buffer energy absorption type counter-force device for testing a tension sensor. The buffer energy absorption type counter-force device comprises an upper counter-force frame, a lower counter-force frame, an upper buffer device and a lower buffer device, the lower counter-force frame and the upper counter-force frame are arranged in a staggered mode, pressing force is converted into pulling force, namely, the tension test of the sensor can be achieved, the upper end of the lower counter-force frame and the lower end of the upper counter-force frame are each provided with a ball cup, and through the automatic centering effect of the ball cups and balls, it is guaranteed that the direction and size of tension transmitted to all positions of the sensor are consistent; the precision of force value transmission is greatly improved, and the structure is simple. Meanwhile, through the upper buffer device and the lower buffer device, the situation that in the calibration process of the te
