Embodiment Construction

[0010] Further illustrate the present invention below in conjunction with accompanying drawing.

[0011] Such as figure 1 and 2 As shown, the plane torsion spring 1 of the present invention is composed of a torsion spring outer ring 2, a torsion spring inner ring 3 and several elastic bodies. Each elastic body is composed of two symmetrical elastic body units, each elastic body unit includes an outer circular hole groove 6, an inner circular hole groove 7 and a connecting beam 8, between the torsion spring inner ring 3 and the inner circular hole groove 7, Both the inner circular hole groove 7 and the outer circular hole groove 6 and between the outer circular hole groove 6 and the torsion spring outer ring 2 are connected by connecting beams 8 . Several outer ring screw holes 5 are evenly distributed on the torsion spring outer ring 2 to realize the connection with the joint load. A number of light holes 4 are evenly distributed on the inner ring 3 of the torsion spring to...

Abstract

The present invention discloses a planar torsion spring for a robot joint, including a torsion spring outer ring, a torsion spring inner ring and a plurality of elastic bodies; the elastic bodies are uniformly distributed around the circumference and connected with the torsion spring outer ring and the torsion spring inner ring respectively at their two ends; each elastic body is composed of two symmetrical elastic body units, each elastic body unit includes an outer circular hole slot, an inner circular hole slot and a connecting beam; the connecting beam connects respectively between the torsion spring inner ring and the inner circular hole slot, the inner circular hole slot and the outer circular hole slot, the outer circular hole slot and the torsion spring outer ring; a wide-angle deformation of the torsion spring is achieved through a series of elastic deformation of the inner and outer circular hole slot.

Description

technical field [0001] The invention belongs to the technical field of robots and relates to a plane torsion spring suitable for robot joints. Background technique [0002] The robot joint is an important part of the robot system, which directly affects the overall performance of the robot system. In recent years, with the rapid development of service robots, the relationship between robots and humans has become closer and closer. Whether the robot system has good interaction with humans and the environment has become a hot spot that people pay attention to. [0003] In the traditional robot design, the joint design mainly adopts the rigid design method, and the motor, reducer, etc. are used as the driving unit of the robot joint. This joint design lacks flexible units, making the robot joints vulnerable to external impact damage, which directly affects the normal operation of the robot. In recent years, people have begun to pay attention to the design methods of flexible ...
