Electromagnetic limiting device for robot mechanism

Abstract

The invention discloses an electromagnetic limiting device for a robot mechanism. The electromagnetic limiting device comprises a spot galvanized solenoid, a guide pin, a magnet, an arc limiting slider and a rubber ring, wherein the spot galvanized solenoid is fixed at one end of the guide pin; the magnet is fastened to the bottom end of the arc limiting slider; the arc limiting slider is provided with the rubber ring at the top inner ring; the arc limiting slider is connected with the guide pin through a flat key. The electromagnetic limiting device does not influence the relative movement of components of the robot mechanism, can automatically generate limitation at a kinematic pair position of the robot mechanism when the limitation is required, is simple in structure, and can be programmatically controlled conveniently.

Description

technical field [0001] The invention relates to the field of robot mechanism limiting devices, in particular to an electromagnetic robot mechanism limiting device. Background technique [0002] In the relative movement between robot mechanisms, it is often necessary to use a limit device to realize the overlapping of components, the change of the motion trajectory of components, and the transformation of the degree of freedom of the mechanism itself. However, the existence of the limit device of the general robot mechanism often hinders the movement of some rods of the robot mechanism, thus greatly reducing the flexibility of the whole mechanism. This problem restricts the academic research of the robot mechanism to some extent. progress, but also restricts the widespread application of many designed robotic mechanisms in engineering. In addition, when the general robot mechanism limit device collides with the limit device, it will inevitably produce a rigid impact on the c...

However, the existence of the limit device of the general robot mechanism often hinders the movement of some rods of the robot mechanism, thus greatly reducing the flexibility of the whole mechanism. This problem restricts the academic research of the robot mechanism to some extent. progress, but also restricts the wide application of many designed robot mechanisms in engineering

In addition, the general robot mechanism limit device often inevitably produces rigid impact on the component when the robot component collides with the limit device, which affects the stability of the component's movement and even causes damage to the component.

[0003] At present, there is a lack of an innovative invention device that has a simple structure and is easy to control, which does not affect the relative movement between the robot mechanism components, and can automatically generate a limit at the kinematic pair position of the robot mechanism when the limit is required.
