Problems solved by technology

[0004] At present, in the domestic wind tunnel, container, water tunnel and environmental test, mechanical processing or installation, construction machinery and fire protection, the space attitude angle test and ventilation mainly realize the space angle test through the combination of relatively independent planar motion mechanism and facade motion mechanism , the ventilation function is carried out through other pipelines, which causes the space attitude angle to be realized only by changing the pitch angle in the surrounding plane, there are discontinuous areas in the space angle, and the corresponding redundant pipelines increase the airflow / liquid flow blockage ratio and space arrangement; while the space multi-degree-of-freedom walking balloon hinge support overcomes and solves this problem well

Embodiment Construction

[0027] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0028] Specifically, a space multi-degree-of-freedom ball joint is provided, including a front ball joint seat, a rear ball joint seat and a front ball joint seat cover;

[0029] The front spherical hinge seat and the rear spherical hinge seat are both hollow structures with openings at both ends. One end of the front spherical hinge seat forms an inner spherical opening, and the opening of the inner spherical surface is a hemisphere, and the inner diameter of the opening end is the diameter of the inner spherical surface. The front spherical hinge The other end of the seat forms a vent pipe interface;

[0030] One end of the rear ball hinge seat forms an outer spherical opening, and the inner diameter of the end of the outer spherical opening is smaller than the diameter of the outer spherical surface, and the other end of the rear ball hinge seat forms a...

Abstract

The invention provides a space multi-degree-of-freedom spherical hinge joint and a supporting device thereof. A front spherical hinge base (2) is connected with a tested model or a machining cutter oran installing piece through a flange or other structures, and the front spherical hinge base (2) is connected to a back spherical hinge base (3) through a front spherical hinge base cover (4) in a matched manner; and in order to achieve spherical hinge supporting space multi-degree-of-freedom changes, space any-angle changes of the front spherical hinge base (2) and the back spherical hinge base(3) is driven by a pitching driving mechanism (5), a yaw driving mechanism (6) and an anti-vibrating anti-rolling mechanism (7). As the limitation of the spherical hinge angel changes, when space anylarge-angle changes happen, multiple spherical hinge supporting devices (1) can be connected in series to achieve the changes.

Description

technical field [0001] The invention relates to the technical field of fluid conveying ball joint support devices, in particular to a space multi-degree-of-freedom ball joint and a support device thereof. Background technique [0002] In wind tunnels, containers, water tunnels and environmental tests, it is a closed-loop or open-loop passage for aircraft, automobiles, engines, sensors, submarines, and ships. Oval or polygonal, the section to be tested is placed inside the test section, and the test section is mostly a polygonal structure, with a rectangular door on the side to facilitate the replacement of the test piece. When performing the space attitude test, remove the test section or open the door of the test section, place the space multi-degree-of-freedom walking ball hinge support on the fixed support wall or bracket of the test section, and place the test piece and the supporting ventilation pipeline with the support device Connected to realize performance testing ...
