Embodiment Construction

[0046] For the sake of reference and clarity, the technical terms involved in this patent are now explained as follows:

[0047] Lever gravity arm (gravity arm): On the lever, the part of the arm (long arm) that is used to carry the mass of the weight and is longer from the fulcrum of the lever.

[0048] Lever arm (moment arm): On the lever, the arm length part (short arm) that is short from the lever fulcrum is used to apply force to the force sensor to be calibrated through the force transmission member.

[0049] Lever fulcrum (fulcrum): On the lever, install a lever support structure (support) to support the mass of the lever and the weight and bear the force of the lever arm.

[0050] Lever force action point (force point): on the lever, the node where the force transmission structure (force transmission member) is installed to transmit the force of the lever arm.

[0051] Lever moment action point (moment point): on the lever, install the node that transmits the action m...

Abstract

The invention provides a force and moment lever and a force and torque standard device. The force and moment lever comprises a lever body, a force transfer part and a torque shaft, wherein the lever body is provided with a support part; the center line of the support part and the plumb line of the length center of the lever body are collinear; the force transfer part is connected with the lever body; the force transfer part is located between the end part of the lever body and the support part; the center line of the force transfer part is parallel with that of the support part; the torque shaft is connected with the lever body; the axis of the torque shaft and the horizontal center line of the lever body are collinear; the axis of the torque shaft is vertical to the center line of the support part. According to the force and moment lever provided by the invention, not only can an acting force be transferred but also applied moment can be transferred, and meanwhile, a tension force and a compression force can be applied to a calibrated force sensor without a force reverse rack, and forward torque and reverse torque can be applied to a calibrated torque sensor without arranging two sets of weights at both ends of the lever, and therefore, the calibration cost is reduced.

Description

technical field [0001] The invention relates to the technical field of a force standard device and a torque standard device, and more specifically, relates to a force and moment lever and a force and torque standard device. Background technique [0002] The force standard device is a standard device that generates standard force values ​​and is used to verify or calibrate force sensors and standard force gauges. According to its principle of force generation, it is divided into four categories: deadweight force standard device, lever force standard device, hydraulic force standard device and superimposed force standard device. Among them, the lever-type force standard device uses the principle of static balance of the lever, with the help of the weight and the corresponding loading mechanism, through the leverage amplification ratio formed by the lever gravity arm and the force arm to amplify the gravity of the weight, in the gravity field with air Force value. [0003] At...
