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

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Such as figure 1 with figure 2 As shown, the present invention provides a large inclination platform based on a six-bar mechanism, which is mainly composed of a worktable 12, a plane six-bar mechanism, a linear drive device and a base 6;

[0026]The planar six-bar mechanism includes connecting rod A1, connecting rod B2, connecting rod C7, connecting rod D8, propulsion platform 3, linear guide rail 5 and support seat 9; except the propelling platform 3, the number of each part is 2, arranged symmetrically and parallelly on the base 6; the connecting rod A 1 forms a plane rotation pair with one end of the connecting rod B 2 and one end of the connecting rod D 8 respectively, and the middle part and the other end of the connecting rod D 8 respectively connect with the one end of the connecting rod C 7 and the support Seat 9 forms a plane revolving pair, the othe...

Abstract

The invention discloses a large-dip-angle inclined platform based on a six-bar mechanism, and belongs to the field of mechanical testing devices. Based on the connecting rod construction of a Stevenson structure chain of the planar six-bar mechanism, rotation of the platform from a horizontal state to a large-dip-angle inclined state is achieved. According to the large-dip-angle inclined platform,a motor and a speed reducer drive a lead screw, so that a propelling table provided with a nut moves on a guide rail front and back, the propelling table serves as a slider in the planar six-bar mechanism to drive the six-bar mechanism to move, and a workbench fixed to the six-bar mechanism obliquely rotates by a large dip angle. According to the large-dip-angle inclined platform, the defect thata traditional hydraulic inclined platform is low in precision or narrow in dip angle range or complex in rotating mechanism is overcome, and the defect that the thrust needed by a slider of a traditional crank slider-crank mechanism inclined platform rapidly changes along with the dip angle of the platform, and the thrust is large when the dip angle is small is overcome. The large-dip-angle inclined platform has the beneficial effects that the bearing capacity of the workbench is large, the thrust needed by the slider gently changes along with the dip angle of the platform, and the dip anglepositioning precision is high, and can be conveniently applied 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...
