Problems solved by technology

The same is true for the matching position of the lever and the base. After the emergence of the blade and blade bearing connection in the traditional technology, advanced bearings such as air bearings, oil bearings, and magnetic bearings have appeared one after another to reduce the resistance moment. It is an air bearing, but the price of this type of bearing is often more expensive, resulting in a higher cost of the mechanical standard machine

Embodiment Construction

[0016] An embodiment of a lever-type mechanical standard machine is Figure 1~4 Shown: includes a base and a lever supported on the base, the lever includes a lever body 3 and an accessory connection structure for connecting with the weight 1 arranged at the right end of the lever body. The right end of the lever body is provided with a lever shaft 28 whose axis extends along the front-to-back direction. Two rotating bearings 25 are arranged at intervals, and each lever shaft corresponds to a pair of stoppers, one of which is to stop the left stopper 27 on the left side of the corresponding rotating bearing, and the other stopper is to stop on the other rotating bearing. The right block 22 on the right side, the rotating bearing and the block constitute a stop structure for blocking and cooperating with the lever shaft to limit the left and right movement of the lever. A support cam is arranged between the two lever shafts, and the top of the support cam is an upwardly convex...

Abstract

The invention relates to a lever type mechanical standard machine. The lever type mechanical standard machine comprises a lever, the lever is provided with a fitting connection structure connected with a corresponding lever connecting piece, the fitting connection structure comprises a supporting rod with a rotation supporting structure arranged at the upper end, the lower end of the supporting rod is provided with a supporting rod arc support surface, the lever is provided with a lever arc support surface in rolling contact fit with the supporting rod arc support surface, the axis of the lever arc support surface, the axis of the supporting rod ac support surface and the axis of the rotation supporting structure are located in the same vertical plane, and the radius of the supporting rodarc support surface is greater than the radius of the lever arc support surface. According to the lever type mechanical standard machine, the resisting moment between the level connecting piece and the lever can be reduced, and the cost can be reduced.

Description

technical field [0001] The invention relates to a lever type mechanical standard machine in the field of measurement. Background technique [0002] At present, the lever plays an important role in the entire force value verification system, and the force standard machine can be divided into two categories: the first type is the fixed standard machine that generates the force value. According to the structure, this type of standard can be divided into net weight type, lever type, hydraulic type and superimposed type; the second type is various portable standards for transmitting force values, which can be divided into dial indicator type according to its measurement principle , Mercury box type, optical type, laser type, strain type, piezomagnetic type, inductive type, capacitive type, vibrating wire type and other force measuring instruments. [0003] The mechanical standard machine uses the force generated by the weight as the standard load, and the force value or torque v...
