Problems solved by technology

When the lever-type mechanical standard machine verifies the device to be verified, the resistance torque between the blade and the blade bearing will affect the verification accuracy. Therefore, in the traditional sense, the resistance torque at this place must be minimized to ensure the verification accuracy. Therefore, in the traditional After the blade and bearing support of the technology, advanced bearings such as air bearings, oil bearings, and magnetic bearings have appeared one after another to reduce the resistance moment, and more air bearings are used, but the price of such bearings is often more expensive. Leads to higher cost of leveraged mechanical standard machines

Embodiment Construction

[0016] Embodiment 1 of a kind of mechanical standard machine is as Figure 1~4 As shown: it includes a base and a lever supported on the base. The lever includes a lever body 3 and a lever shaft 4 that is arranged on the left end of the lever body and extends along the front and rear directions. The lever shaft and the lever body together form a T font structure. Two rotating bearings 10 are arranged at intervals along the front and rear directions on each lever shaft, and each lever shaft corresponds to a pair of blocks, one of which blocks 8 on the left side of the corresponding rotating bearing, and the other block 8 blocks on the left side of the corresponding rotating bearing. On the right side of the other rotating bearing, 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. One of the lever shafts is provided with a torque output shaft 13 for torque output. ...

Abstract

The invention relates to a mechanical standard machine. The mechanical standard machine comprises a base and a lever supported on the base and provided with a force output structure, the base comprises a support rod with a rotation support structure at the lower end, the upper end of the support rod is provided with a support rod arc support surface, the lever comprises a lever body extending along the left-right direction, the lever body is provided with a lever arc support surface in rolling contact fit with the support rod arc support surface, the axis of the lever arc support surface, theaxis of the support rod arc support surface and the axis of the rotation support structure are in the same vertical plane, the radius of the support rod arc support surface is greater than the radiusof the lever arc support surface, the lever body is also provided with a lever shaft coaxial to the lever arc support surface, and the mechanical standard machine also comprises a stop structure usedfor being in stop fit with the lever shaft to limit the left-right movement of the lever. According to the mechanical standard machine, the resisting moment at a support position can be reduced, and the cost can be reduced.

Description

technical field [0001] The invention relates to a mechanical standard machine in the field of metrology. Background technique [0002] At present, the lever plays an important role in the whole force value verification system, and the mechanical 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 lever-type mechanical standard machine uses the force generated by the weight as the standard load, and the force value or torque...
