Problems solved by technology

If manual intervention takes time and effort, for general applications, most of the existing multi-DOF docking platforms are more complicated and costly. Therefore, a simple five-DOF mechanical adaptive auxiliary docking platform is proposed. After the workpiece has been accurately aligned, it is in the rising stroke. Due to various working conditions, such as machining errors, deformation, vibration, force, etc., or human factors act on the workpiece, a small amount of movement occurs on the workpiece during the rising stroke. Offset, the geometric center of the slide rail and the chute does 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

Abstract

The invention discloses a mechanical self-adaptive auxiliary docking platform which comprises a translational mechanism and a rotary mechanism, wherein the translational mechanism can realize two moving freedom degrees and one rotational freedom degree in a plane, the rotary mechanism can realize two quadrature rotational freedom degrees in a space and is arranged above the translational mechanism and used for controlling the on-off of an electromagnetic brake as well as separation and reunion of a wedged block to realize the functions of deadlocking and unlocking. The invention has the functions of sensitive self-adaptation and self-regulation and can prevent a workpiece from overlarge torsion generated during trace deviation in a coordination process, thereby enabling assembly to be successful and enhancing the assembly efficiency.

Description

technical field [0001] The invention belongs to the technical field of flexible assembly, and in particular relates to a five-degree-of-freedom mechanical self-adaptive auxiliary docking platform suitable for assembly. Background technique [0002] When the workpiece is assembled, the posture position of the workpiece is often not in the ideal state, but there is a certain inclination or twist between the ideal state. When the matching area is relatively large, this inclination or twist will seriously affect the transfer. Therefore, it is necessary to make timely fine adjustments to the workpiece to realize the assembly process. If manual intervention takes time and effort, for general applications, most of the existing multi-DOF docking platforms are more complicated and costly. Therefore, a simple five-DOF mechanical adaptive auxiliary docking platform is proposed. After the workpiece has been accurately aligned, it is in the rising stroke. Due to various working conditio...
