Problems solved by technology

The UPS rope-driven branch chain adopts a linear motion unit, so that the power unit (motor, etc.) can be placed outside the branch chain, which reduces the weight of the traditional linear drive mechanism and makes the structure more compact, which solves the problem caused by the simulation of muscle expansion and contraction of the existing bionic mouth and jaw robot. swing problem

Abstract

The invention discloses a rope-driven parallel bionic stomatognathic robot with higher pair constraints. By researching the physiological structure and redundant drive characteristics of the human stomatognathic system, including mandibular muscles, bones, temporomandibular joints and the like, and comprehensively considering the characteristics of chewing muscles and the temporomandibular joints,a rope-driven spatial redundant drive parallel mechanism with higher pair constraints is designed. Six UPS rope-driven branched chains simulate six muscles, which play a main role, of the stomatognathic system, and the six muscles are left and right masseter muscles, temporal muscle and lateral pterygoid muscle respectively. Two point contact higher pairs represent the temporomandibular joints, the structure is in bilateral symmetry, and the bionic degree is high. The UPS rope-driven branched chains do not swing in a moving process, so that the problem that force action lines are inconsistenteasily when the muscles are simulated by other driving mechanisms is solved. Meanwhile, motors are placed outside the branched chains, so that the weight and size of a linear driving mechanism are reduced. The robot has a good application prospect in the disciplines of dental science, food science, biomechanics, prosthetic restoration and the like.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a high-pair constraint rope-driven parallel bionic mouth-jaw robot. Background technique [0002] The bionic mouth and jaw robot can not only simulate the movement of the mandible and temporomandibular joint, but also reproduce the occlusal force of the teeth and the force of the temporomandibular joint, and can quantitatively test the prosthesis material through in vitro simulation. Therefore, the bionic mouth and jaw robot is becoming more and more More and more are used in performance testing of new materials, newly designed dentures and temporomandibular joint prostheses. In the design and research of bionic oral and jaw robots, corresponding mechanisms are used to complete the required functions for their respective application fields. However, there are still certain bionic defects in the mechanism, as follows: [0003] Due to the fact that the driving and transmission system ...
