Abstract

The invention discloses a loading mechanism for a dead weight type low force standard device. The loading mechanism comprises the components of a base which is arranged in a vertical direction; a linear motion module which is arranged at one side of the base; a lifting worktable which is connected with the linear motion module, wherein the linear motion module can drive the lifting worktable to perform vertical motion; and a loading frame which is suspended at one end of the dead weight type low force standard device in use, wherein the linear motion module can drive the lifting worktable to perform vertical motion in the loading frame. The loading mechanism for the dead weight type low force standard device has a simple structure and is furthermore suitable for performing high-precision measurement on a low force.

Description

technical field [0001] The invention relates to the field of force value measurement, in particular to a loading mechanism for a static weight type micro force value standard device. Background technique [0002] The loading mechanism is an important component of the deadweight force standard machine. The loading mechanism of the traditional force standard machine is generally composed of a moving beam, a lifting device, a guiding mechanism, etc., and the structure is relatively complicated and takes up a lot of space. In order to expand the lower limit of the force value measurement range, some new deadweight force standard machines use a balance mechanism to balance the weight of the loading mechanism and the weight suspension system, and its primary load is the force value reproduced by the first-level weight . However, the existing loading mechanism has a complex structure, which is not conducive to the balance of its weight and the improvement of the sensitivity of th...
