Embodiment Construction
[0018] 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.
[0019] An automatic return three-degree-of-freedom combined floating support mechanism of the present invention includes a plurality of floating support mechanism units 7 and a combined floating platform 8, and the structure of each floating support mechanism unit 7 is as follows 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. The combined floating platform 8 is installed on the floating platforms 2 of the plurality of floating support mechanism units 7 .
[0020] 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 ball...

The invention relates to a self-return planar three-degree-of-freedom combination floating supporting mechanism and relates to the technical field of equipment loading and unloading auxiliary platformdevices. 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 and restrained 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 centerposition. 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 an automatic return plane three-degree-of-freedom combined floating support mechanism. 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 combined floating support mechanism, so as to realize the manual fine-tuning of the position of the assembly parts in the direction of three degrees of freedom in the plane to achieve precise docking, and can automatically return without e...
