The device is simple in structure, novel and reasonable in design idea, simple in operation, high in artificial intelligence, small in weight shaking and working noise and stable in motion, so that the service life of thrust rods can be greatly prolonged; and the sleeve type guide rods are convenient and fast, sothat calibration efficiency can be enhanced.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a double support type net weight force calibration device. Background technique [0002] The force calibration device is a tool for force value measurement, and is often used in measurement occasions. [0003] At present, our net-weight force calibration machine adopts the weight stacking type, and the calibration must be stacked layer by layer sequentially and the falling off efficiency is low; the rise and fall of the weights is caused by the noise of the turbine drive; the adjustment of the distance during calibration is manual. It takes a lot of effort to manually rotate the screw to adjust the height of the wheel. When calibrating the sensor, it is all calculated manually. The guide rod is directly connected and fixed.

[0003] At present, our net-weight force calibration machine adopts the weight stacking type, and the calibration must be stacked layer by layer sequentially and the falling off efficiency is low; the rise and fall of the weights is caused by the noise of the turbine drive; the adjustment of the distance during calibration is manual. It takes a lot of effort to manually rotate the screw to adjust the height of the wheel. When calibrating the sensor, it is all calculated manually. The guide rod is directly connected and fixed. During the calibration process, the center of gravity will be high, and the lifting of the weight rod will cause shaking. etc., which is not conducive to the calibration of the sensor

Since the weight rod and the weight are in a free state at this time, there will be swings. When the swing is severe, the number during calibration will change with the swing of the weight rod, which greatly increases the calibration time and reduces the calibration efficiency. The thrust rod drives the weight up and down, and its righting mechanism can guarantee the left and right swing, but there will still be a slight shaking in the front and rear. When the thrust rod goes up and down when the weight is pushed, the verticality changes, resulting in a large Friction, which seriously affects the service life of the thrust rod
