Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 4 to Figure 7 As shown, the prosthetic centroid measuring device of the present invention includes a clamp (rotatable clamp and clamp seat) 1, a load-bearing disc 2, three load cells 3, a base 4, a data acquisition module 5 and computer processing systems 6,7.

[0018] The entire fixture seat together with the rotatable fixture 1 is placed on a load-bearing disc 2, and the disc 2 rests on three load cells 3, and the three load cells 3 are fixed on the base 4, and the three load cells 3 measure Support the reaction force, and transmit the measurement data to the data acquisition module 5 and the computer processing system 6, and the computer 6 processes the data to calculate the mass and center-of-mass coordinates of the prosthesis.

[0019] The invention is based on the static weighing technology, establishes the balance equation ca...

Abstract

The invention relates to a measuring device of mass center of prosthesis, comprising a rotatable fixture, a base of fixture, a load bearing disc, a base, three weighing sensors, a data acquisition module and a computer process system. The rotatable fixture and the base of fixture are arranged on the load bearing disc and the load bearing disc is arranged on the three weighing sensors. The three weighing sensors are fixed on the base and can send the measured data of reaction of supports to the data acquisition module and the computer process system. The computer processes the data and then works out the mass of the prosthesis and the coordinate of the mass center. The invention has the advantages of simple structure, convenient operation and rapid and exact measurement of the mass of the prosthesis and the coordinate of the mass center. The invention is a device with functions of measuring, researching and developing. The same measuring principle can be popularized in the mass center measurement of other complex objects.

Description

technical field [0001] The invention relates to a device for measuring the center of mass, in particular to a device for measuring the center of mass of a prosthesis. Background technique [0002] Among the existing national standards for prosthetic products, they mainly focus on the processing quality of prosthetics. In the domestic prosthesis industry, the device for measuring the center of mass of the prosthesis is still in a blank state. [0003] Modern prosthetic products have better bionic functions by adopting new materials, improving transmission methods, and improving the level of intelligence. In order to make the prosthesis closer to the healthy limb and further reduce the difference in the physiological and psychological feelings of the amputee between the prosthetic and the healthy limb, in addition to making it have the characteristics of light weight, high strength, and high performance, each part of the prosthesis should also be made The weight and center o...
