A four-degree-of-freedom passive follow-up gravity balance device

Abstract

The invention discloses a passive following gravity balancing device with four degrees of freedom. The passive following gravity balancing device with four degrees of freedom mainly comprises a pedestal arranged on a base bracket, the front section of a tumbler pivoted to the pedestal, and the rear section of the tumbler pivoted to the front section of the tumbler, wherein a pulley block A and a pulley block B are respectively connected with two different positions of the rear section of the tumbler, a steel wire rope is arranged between the pulley block A and the pulley block B, one end of the steel wire rope is connected with a balance weight device capable of rotating around the shaft while the other end is connected with a transfer fixture capable of rotating around the shaft and used for transferring a test object, and moreover, the transfer fixture is located at the end of the steel wire rope far away from the front section of the tumbler. The passive following gravity balancing device with four degrees of freedom has beneficial effects of simple structure, fewer processing parts, light weight, low cost and good economical efficiency.

Description

technical field [0001] The invention relates to a test device, in particular to a test device which can realize the four-degree-of-freedom movement of the test object and can passively follow the gravity balance. Background technique [0002] The four-degree-of-freedom passive follow-up gravity balance device is mainly used in the field of engineering experiments to realize the gravity balance function of the test object. When the test object is tested, especially the test without the influence of gravity, it is required that the test equipment can provide the gravity balance function, and can dynamically balance its gravity following the movement of the test object. At present, similar devices at home and abroad generally have complex structures and high costs. Contents of the invention [0003] The invention provides a gravity balance device capable of four-degree-of-freedom passive follow-up with a simple structure, so as to solve the defect that the existing devices f...
