Embodiment Construction

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic way, so they only show the structures related to the present invention, and the directions and references (eg, up, down, left, right, etc.) may only be Used to aid in the description of features in the drawings. Therefore, the following detailed description is not to be taken in a limiting sense, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0022] like Figure 1 to Figure 4 The illustrated universal lever system with adjustable center of gravity, the preferred embodiment of the present invention, includes a lever. The center of the lever along its axial length direction has a resultant force loading area, and the lever is respectively provided with a component force l...

Abstract

The general lever system with the adjustable gravity center comprises a lever, the center of the lever in the axial length direction is provided with a resultant force loading area, and the lever is sequentially provided with a component force loading area and a gravity center adjusting area from the center to the two sides in the axial length direction; the resultant force loading area comprises a plurality of resultant force bolt groups which are distributed at intervals along the axial length direction of the lever; the component force loading area comprises a component force bolt group which is adjustably arranged along the axial length of the lever; the gravity center adjusting area comprises at least two gravity center adjusting assemblies which are arranged along the axial length of the lever in an adjustable mode. The lever ratio can be adjusted, and when the resultant force acting point of the lever is located in the middle bolt hole, balance weight and gravity center adjustment do not need to be considered; when the resultant force acting point of the lever is not in the center, the gravity center can be adjusted to the force center through the counterweight system; the gravity center adjusting device can be matched with different balancing weights according to different positions, and meanwhile the gravity center can be adjusted more accurately by adjusting the positions of the balancing weights.

Description

technical field [0001] The invention relates to levers, in particular to the technical field of lever center of gravity adjustment, and in particular to a universal lever system with adjustable center of gravity. Background technique [0002] In structural-level static and fatigue tests, a large number of lever systems are used to load the test pieces. The levers used in the lever system are generally divided into general-purpose levers and special-purpose levers. Regardless of the type of lever, the point of action of the force and the center of gravity of the lever system are not on the same line of action. Due to the self-weight of the lever loading system, additional force will inevitably be generated on the test piece during the test loading process. In the static / fatigue test, the influence of the additional force of the lever system needs to be minimized. The traditional method is to calculate the gravity center and weight of the lever system after the assembly is co...
