Mechanical limiting structure

Abstract

The invention discloses a mechanical limiting structure. The mechanical limiting structure is applied to industrial robot equipment, photoelectric precision tracking equipment, radar equipment and other large or relatively large equipment with a rotating shaft, a precision device, and high safety requirements and the like. The problem to be solved is that the large or relatively large equipment with the rotating shaft series need to have the mechanical limiting structure with good buffering effect and the shaft with wide range of rotating angles, but the shaft bears larger curving force vertical to the rotating axis due to nonsymmetrical wear-stress during the limiting buffering process. By means of the isomerization design of two buffering module mechanisms and the isomerization design oftwo ends of a collision block, the effect that the rotating shaft only bears the torsion load during the limiting buffering process is realized, and the safety and reliability of the system are improved on the basis of ensuring wider range of rotating angle of the rotating shaft of the mechanical limiting mechanism.

Description

technical field [0001] The invention relates to the technical field of mechanical limit mechanisms, in particular to a mechanical limit mechanism. Background technique [0002] In order to ensure that industrial robots can work safely and reliably on automated or intelligent production lines, limit measures such as structural hard impact limit, force sensing self-locking limit, and soft limit are generally adopted in many cases. In order to improve the reliability of the limit, a common limit method combining mechanical limit and electric limit is often adopted. However, the mechanical limit methods often used in the current industrial robots are often accompanied by relatively large impacts. Although the safety of people or objects around is guaranteed, it has a relatively large safety hazard for the industrial robots themselves. With the improvement of the precision of industrial robots and the expansion of the functions that can be realized, the large impact of the mecha...

[0003] The technical problem to be solved by the present invention is: to overcome the requirements of mechanical limit mechanism with good buffering effect and large range of rotation angle of the shaft system in large or relatively large equipment with rotating shaft system, but due to asymmetrical force in the process of limit buffering This leads to the problem that the shafting bears a large bending force perpendicular to the axis of rotation
