Embodiment 1

[0048] In practice, the masticating robot includes a static platform I, six driving devices II, a booster device IV, a mandibular motion platform III and a motion control system.

[0049] Such as figure 2 As shown, the static platform includes a lower support plate 1, a steering gear bracket 2, an upper and lower plate support 3, an upper support plate 4, and an afterburner support 5. Three upper and lower plank supports 3 are evenly distributed on the circumference between the lower support plate 1 and the upper support plate 4, and the two ends are fixedly connected with the lower support plate 1 and the upper support plate 4 by flat head bolts respectively. The six steering gear brackets 2 are in groups of two, and three groups are evenly distributed on the lower support plate in a circle. There are holes on the steering gear bracket 2, which are connected to the lower support plate 1 through flat head bolts and nuts. The three booster supports 5 are evenly distributed on...

Abstract

The invention discloses a six-freedom-degree chewing force control and monitoring system aiming at solving the problem that in the prior art, because the stress situation of all parts of teeth cannotbe monitored or controlled in the chewing process and accordingly the accuracy rate of chewing simulation is low, credibility of the chewing simulation result is low. According to the six-freedom-degree chewing force control and monitoring system, by achieving the six-freedom-degree movement of a mandibular movement platform and vertical movement of a maxillary installation platform, the chewing movement of human oral cavities is more accurately simulated, the stress situation of all the parts of the teeth is automatically monitored and controlled in the chewing process in real time, and therefore the accuracy rate of chewing simulation is increased, and the result credibility of chewing dental department detection can be high. The six-freedom-degree chewing force control and monitoring system is suitable for the technical field of parallel robots.

Description

technical field [0001] The invention relates to the technical field of parallel robots, in particular to a six-degree-of-freedom masticatory force control and monitoring system. Background technique [0002] The maxilla, muscles of mastication, mandible, and temporomandibular joint together constitute the human masticatory system. Mandibular mastication is driven by masticatory muscles, has 6 degrees of freedom in space, and can be simplified into a periodic motion process of multiple motion modes. The chewing machine is a device that assists stomatology or conducts food science testing based on human jaw movement. The development and design of the chewing machine involves many disciplines such as mechanism, control engineering, biomechanics, and mechatronics engineering. [0003] By reproducing the chewing movement of the human jaw, the chewing machine can complete various scientific experiments that are difficult to complete in the real human mouth. For example, in the ...
