Embodiment Construction

[0016] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] An automatic return three-degree-of-freedom floating support mechanism of the present invention is as attached Figure 1 to Figure 3 As shown, it includes a base 1, a floating platform 2, a sliding ball 3, a spring 4, a vertical fixed block 5 and a horizontal fixed block 6. There are multiple spherical grooves on the base 1 and six sliding balls 3 are installed. The floating platform 2 rides on the six sliding balls 3 to form a spherical pair, so the floating platform 2 can slide and rotate horizontally relative to the base 1 . Six springs 4 are used to connect the base 1 and the floating platform 2, two vertical fixed blocks 5 are fixed on the base 1, the base 1 is rectangular, and the two vertical fixed blocks...

Abstract

The invention relates to a self-return planar three-degree-of-freedom floating supporting mechanism and relates to the technical field of equipment loading and unloading auxiliary platform devices. Relative motion of an upper part floating platform and a supporting base in a supporting plane is achieved by utilizing a spherical pair, the floating platform and the supporting base are connected andrestrained through six springs, and manual fine adjustment on the floating platform in the three degree-of-freedom directions of the supporting plane requires overcoming horizontal force and torque. Under the condition of an initial state and without external force, spring force borne by the floating platform is balanced, so that the floating platform automatically returns to a center position. Therefore, the manual fine adjustment on a posture of an assembling unit in the planar three degree-of-freedom directions can be achieved and accurate butting is realized, and self-return can be realized without the external force.

Description

technical field [0001] The invention relates to the technical field of equipment loading and unloading auxiliary platform devices, in particular to a plane three-degree-of-freedom floating support mechanism with automatic return. Background technique [0002] At present, when assembling heavy parts at the bottom of vehicles and large equipment, mobile carrying platforms are usually used for handling and lifting. During this process, the translation control accuracy of the carrying platform does not meet the docking accuracy, and assembly is difficult and difficult to control. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to design a floating support mechanism, so as to realize manual fine-tuning of the assembly parts in the direction of three degrees of freedom in the plane to achieve precise docking, and can automatically return to position without external force .
