Embodiment Construction

[0014] Preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0015] figure 1 It is a structural schematic diagram of a six-degree-of-freedom passive follow-up test platform of the present invention, such as figure 1 As shown in the example, the platform includes:

[0016] Base 1, support cylinder 2, spring 3, spring guide rod 4, support sleeve 5, locking screw 6, floating bracket 7, transition flange 8, spherical plate 9, cover plate 10, bearing 11, etc.

[0017] When the platform is not in use, use the locking screw 6 to lock the test platform.

[0018] A cover plate 10 is installed on the floating support 7, and four threaded holes are evenly distributed in the circumferential direction on the floating support 7, and support sleeves 5 are all equipped with, and the spring guide rod 4 is threadedly connected in the support sleeve. Spring 3 is housed in between, also is spherical surface fit between floating ...

Abstract

The invention discloses a six-degree-of-freedom passive follow-up test platform, which comprises: a base (1), a support cylinder (2), a spring (3), a spring guide rod (4), a support sleeve (5), and a locking screw (6), floating support (7), transition flange (8), spherical plate (9), cover plate (10), bearing (11) etc., the present invention a kind of six degrees of freedom passive follow-up test platform, can To adapt and compensate for the positional deviation between the two test objects, the six degrees of freedom movement of the transition flange (8) and the floating support (7) is realized by using the spring and the spherical surface, and then the installation on the transition flange (8) is realized. ) on the follow-up function of the test object. The beneficial effects of simple structure, few parts, light weight and good economy are obtained.

Description

technical field [0001] The invention relates to a test device, in particular to a test device capable of realizing the six-degree-of-freedom adaptability required between two test objects. Background technique [0002] The six-degree-of-freedom passive follow-up test platform is mainly used in the field of engineering testing to realize the six-degree-of-freedom position deviation compensation function between two test objects. [0003] At present, similar devices at home and abroad are generally more complicated and costly. The present invention is a test platform with simple structure and capable of passive follow-up of six degrees of freedom. It has good economy, low cost, good versatility, and can be popularized and used. [0004] Do not find description or report similar to the present invention at present, also do not collect similar data both at home and abroad. Contents of the invention [0005] When two test objects are tested, especially the capture and locking ...
