Three-axis cloud table with double-arm structure

Abstract

The invention provides a three-axis cloud table with a double-arm structure. The three-axis cloud table comprises a machine body and a cloud table support connected with the machine body, the cloud table support comprises a first connecting arm and a second connecting arm, and a pitch axis motor is fixedly connected to the first connecting arm. A lens assembly is mounted on a rotary shaft of the pitch axis motor, and a bearing connected with the rotary shaft is arranged on the second connecting arm. Under supporting of the double arms, the lens assembly can be stably mounted on the rotary shaft, and the flexural moment phenomenon occurring due to one-way stress of the pitch axis motor and the connecting arms is avoided.

Description

technical field [0001] The invention relates to a cloud platform, in particular to a three-axis platform with a double-arm structure. Background technique [0002] As a supporting device for installing and fixing electrical equipment such as cameras, the pan / tilt is installed on a carrier, and it is widely used in fields such as photography, photography, and monitoring. In the prior art, the pan / tilt is generally a single-arm structure. For example, the patent number is CN201780000670.5, which is a patent document titled a pan / tilt assembly and a handheld pan / tilt camera. The pitch axis assembly is only supported by a single arm, and its roll The weight of the axis assembly and the camera will easily cause the bending moment of the pitch axis assembly and the gimbal support, which will affect the stable torque output of the motor in the pitch axis assembly during normal operation, easily cause fatigue damage to the motor, and shorten the life of the motor. The service life,...

In the prior art, the pan / tilt is generally a single-arm structure. For example, the patent number is CN201780000670.5, which is a patent document titled a pan / tilt assembly and a handheld pan / tilt camera. The pitch axis assembly is only supported by a single arm, and its roll The weight of the axis assembly and the camera will easily cause the bending moment of the pitch axis assembly and the gimbal support, which will affect the stable torque output of the motor in the pitch axis assembly during normal operation, easily cause fatigue damage to the motor, and shorten the life of the motor. service life, and after a bending moment occurs, the lens will deviate from the axis of the yaw axis, so that the center of the hand-held direction, the center of the lens, and the subject are not in a straight line
