Abstract

A four-degree-of-freedom serial-parallel hybrid posture alignment vibration-isolation platform provided with triangular branches mainly comprises a base, a movable platform, three linear drive units, the three triangular branches, a rotary plate bearing and a rotary plate. Each linear drive unit is composed of an installing block, a linear module and an assistance part, wherein the installing block is fixedly connected to the base, the linear module is installed on the installing block, one end of the assistance part is connected with a baffle at the end of the linear module, and the other end of the assistance part is connected with a slider of the linear module. Each triangular branch comprises a first ball joint base, a first ball joint, a vibration isolator, a two-ball-joint triangular frame and two second ball joint bases, wherein the first ball joint base is installed on the slider of the corresponding linear module, one end of the vibration isolator is connected to the first ball joint, the other end of the vibration isolator is connected with the two-ball-joint triangular frame, and the two ball joint bases are connected to the movable platform. An outer ring of the rotary plate bearing is installed on the movable platform, and the rotary plate is installed on an inner ring of the rotary plate bearing. The four-degree-of-freedom serial-parallel hybrid posture alignment vibration-isolation platform is large in stiffness and good in vibration isolation effect and dynamic performance.

Description

technical field [0001] The invention relates to a series-parallel hybrid mechanism, in particular to an attitude-adjusting vibration-isolating device. Background technique [0002] With the improvement of people's living standards, human beings are increasingly dependent on vehicles. Affected by the unevenness of the road surface during driving, the vehicle will produce multi-dimensional compound bumps such as vertical, roll and pitch of the vehicle body. If the on-board items are directly rigidly connected to the car body, the multi-dimensional vibration generated by the vehicle under poor road conditions will have a serious impact on the transportation of fragile and delicate items and on-board equipment that require attitude adjustment. The attitude-adjusting vibration isolation platform can separate the on-board items from the car body, which can not only reduce the vibration transmitted from the car body to the on-board items, but also precisely adjust the attitude of ...
