Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with technical solutions and accompanying drawings.

[0026] The imitation mandible movement robot includes a static platform, a driving device, a kinematic branch chain and a mandibular platform, and adopts servo drive to realize the movement of mandible opening, closing and occlusal.

[0027] Concrete action process of the present invention

[0028] According to the jaw movement to be realized, the motor 5 transmits the rotation to the lead screw 7 through the coupling 6, and the lead screw 7 drives the lead screw nut 8 to move, which is converted into a linear motion of the lead screw nut 8. The workbench 10 is fixed on the lead screw nut 8, realized that the workbench 10 moves linearly on the guide rail 13. The two ends of the motion branch chain III are respectively threaded with the joint connection block 9 fixed on the workbench 10 and the mandibular joint connection b...

Abstract

The invention discloses a mandibular movement imitating robot, which belongs to the technical field of bionic robots and can provide a scientific means for the research of the dentistry, the food science and the biomechanics. The mandibular movement imitating robot comprises a static platform, six driving devices, six movable branched chains and a mandibular platform, wherein the driving devices consist of motors and ball screw pair transmission systems and are used for driving the six movable branched chains to realize movement of the mandibular platform in a three-dimensional space. The mandibular movement imitating robot has the advantages that the dimension diameters of a human body mandibular system and the biomechanical characteristics of a mandibular muscle driving system are synthetically considered, the movement function and a chewing environment of a human mandible can be truly reproduced, and the requirements of realness in movement locus and rationality in occlusion strength are satisfied.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, and relates to a mandible-simulating robot. Background technique [0002] The research on mandible-imitating robot began in the early 1990s. It is a kind of robot that can simulate human jaw movement behavior and reproduce human jaw movement and force. It is an engineering science that integrates many technologies such as mechanism, kinematics, dynamics, perception system, motion control, biomechanics, and mechatronics, and can be directly applied to the research fields of dentistry, food science, biomechanics, etc. . [0003] Domestically, there are few researches in the field of imitating jaw movement robots. The applicant of this patent once proposed an anthropomorphic flexible cable-driven redundant parallel masticating robot. The mechanism is driven by flexible cables and has good flexibility. Foreign research was carried out earlier, and some research results have been obtained in t...
