Abstract

The invention provides a two-shaft two-frame mechanism with a ball head connecting rod transmission mechanism. An azimuth shafting and a pitching shafting are staggered, the azimuth shafting is moveddownwards, and the traditional azimuth shafting position is simplified into an azimuth bearing component; due to the simplified azimuth bearing component, a motor is not included, and the size is reduced, so that the large-angle rotation of a platform can be realized. The azimuth shafting which moves downwards is connected with the azimuth bearing component through ball head connecting rods. According to the two-shaft two-frame mechanism with the ball head connecting rod transmission mechanism, according to the provided ball head connecting rod transmission, the characteristic that a parallelogram is easy to deform is utilized, the structure is simple, and the weight is light; in the transmission process, one connecting rod provides thrust, and the other connecting rod provides pulling force, so that the stable rotation can be ensured; and in order to ensure the transmission precision of the ball head connecting rods, ball heads are ground in ball head pressing covers and ball head supports, so that the ball heads are guaranteed to rotate smoothly without the stuck phenomenon, and the ball heads are mounted on the two-shaft two-frame structure after the ball heads are free of a dead point.

Description

technical field [0001] The invention relates to a ball joint transmission mechanism, which is suitable for the rotation transmission between parts and belongs to the technical field of photoelectric equipment mechanical design. Background technique [0002] The transmission between parts is one of the most common designs in two-axis and two-frame products. Traditional two-axis and two-frame products distribute the azimuth and pitch axis systems on one plane. When the size of the platform is determined, the distribution of the azimuth and pitch axis systems on one plane will limit the rotation range of the frame angle, thus objectively affecting the performance indicators of the optoelectronic equipment. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes a two-axis two-frame mechanism with a ball-joint link transmission mechanism, which staggers the azimuth and pitch axis systems and moves the azimuth ...
