A tilting platform with large inclination angle based on six-bar mechanism

Abstract

The invention discloses a large-inclination-angle tilting platform based on a six-bar mechanism, which belongs to the field of mechanical testing and testing devices. The invention realizes the rotation of the platform from a horizontal state to a large inclination angle state based on a connecting rod configuration of a Stevenson structure chain of a planar six-bar mechanism. In the present invention, the lead screw is driven by the motor and the reducer, so that the propulsion table with the nut moves back and forth on the guide rail, and the propulsion table is used as a slider in the plane six-bar mechanism to drive the six-bar mechanism to move, so that it is fixed on the six-bar mechanism. The workbench is tilted and rotated at a large inclination angle. The present invention overcomes the disadvantages of low precision of the traditional hydraulic tilting platform, small range of inclination angle or complex rotation mechanism, and also overcomes the disadvantages of the traditional crank slider mechanism that the required thrust of the tilting platform slider changes drastically with the platform inclination angle, and the thrust is large when the inclination angle is small. The invention has the advantages of large load-carrying capacity of the workbench, gentle change of the required thrust of the slider with the inclination angle of the platform, high inclination angle positioning accuracy, etc., and is convenient for application in related fields.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing equipment and testing devices, and particularly relates to a large-inclination tilting platform based on a six-bar mechanism, which realizes the platform from the Rotation from a horizontal state to a tilted state with a large inclination angle. Background technique [0002] In the development of mechanical testing equipment, a working platform that can be changed from a horizontal state to an inclined state is often required. For example, when testing the height of the center of mass of a car, a force measuring platform is required to be fixed on the working platform to carry the car, and the working platform is tilted at a given angle. , collect force measurement data to calculate the height of the center of mass; in the static calibration of seismometers in the field of geosciences, a working platform that can accurately change from horizontal to a specific inclination angle is requi...

Problems solved by technology

Such a situation causes two problems: 1. Since the initial driving force is very large, the maximum load of the power equipment needs to be selected very large

2. In the process of increasing the inclination angle, the required driving force decreases rapidly from a large one, and the huge fluctuation of the driving force is not conducive to the precise control of the angle of the working platform
