Mechanical flexibility space buttjunction platform

Abstract

The present invention discloses one kind of mechanical flexible spatial butt-jointing platform, and features that the mechanical flexible spatial butt-jointing platform has one mechanical flexible assembling platform comprising one pedestal, one joint body and one floating body. The pedestal has one circular groove in the upper end and balls distributed homogeneously inside the groove; the joint body is one truncated sphere, whose bottom plane is located inside the circular groove and contacted with the balls in the groove and spherical crown possesses homogeneously distributed balls; and the floating body covering the joint body has arced groove in the bottom surface to contact with the balls in the joint body. The present invention has the obvious effect of self-adaptive regulating function to ensure successful spatial butt-jointing with high quality and small torsional force.

Description

technical field [0001] The invention belongs to the technical field of space docking, and in particular relates to a mechanically flexible space docking platform suitable for space docking. Background technique [0002] Existing industries have higher and higher requirements for space docking technology, such as workpiece alignment in high-precision industrial manufacturing, space station alignment, pipeline docking in medical and chemical engineering, and circuit connection in network electronic technology, etc., which affect the docking accuracy. An important factor is the relative parallelism between the approaching surfaces of the two objects. Assembly, machining, or wedging of the object itself can cause non-parallelism. The first thing to consider in the assembly process is the alignment between the two objects to be assembled. Such as figure 1 As shown, in engineering, it is often necessary to fix the workpiece on the docking platform, and then the docking platform...

Problems solved by technology

[0003] However, it is not comprehensive to consider the exact alignment between the workpiece and the chute. After the workpiece has been accurately aligned, it is in the rising stroke. Due to various working conditions, such as vibration, force, etc., or Human factors act on the workpiece, resulting in a slight deviation of the workpiece during the rising stroke, and the geometric centers of the slide rail and the chute do not coincide, which directly affects the assembly accuracy

At the same time, there will be a lateral force acting on the chute, which will increase the friction between the slide rail and the chute, and eventually cause damage to the workpiece and the docking body

[0004] Its disadvantages are: the docking platform is not flexible, and has no self-adaptive or self-adjusting function. When the workpiece is slightly shifted during the alignment stroke, the torque is too large, which will cause workpiece damage or alignment failure.
