Archimedes spiral based dynamic loading device

Abstract

The invention discloses an Archimedes spiral based dynamic loading method, which comprises a left coupling portion, and is characterized in that the right side of the left coupling portion is directlyconnected with a left Archimedes spiral torsion spring, the left Archimedes spiral torsion spring is connected with a right Archimedes spiral torsion spring through connection extension, a through slot is opened in the radial direction between the left torsion spring and the right torsion spring, and the right side of the right Archimedes spiral torsion spring is directly connected with a right coupling portion. The loading device is manufactured by sequentially processing the same blank, and the processing process comprises the steps of performing rough turning after raw material forging, then carrying out quenching and subsequent tempering, performing fine turning, carrying out quenching treatment after fine turning, then cutting Archimedes spirals of the left Archimedes spiral torsionspring and the right Archimedes spiral torsion spring through linear cutting and milling two threaded holes of the left coupling portion and the right coupling portion, then grinding inner holes and respective end faces of the left coupling portion and the right coupling portion, and finally cutting keyways of the left coupling portion and the right coupling portion through linear cutting and radial through slots of the left Archimedes spiral torsion spring and the right Archimedes spiral torsion spring. The loading device can have the advantages of large torque loading range, good linearity,high loading accuracy and compact structure.

Description

technical field [0001] The invention belongs to the technical field of core components of industrial robots, and in particular relates to the design and realization of a dynamic loading device based on an Archimedes spiral. Background technique [0002] Harmonic reducer is the core component of industrial robots, which plays an important role in promoting the development of industrial robots. The performance of the harmonic reducer directly affects the quality of the industrial robot. Effective and high-precision testing of the performance indicators of the harmonic reducer is an important basis and effective way to improve the performance of the harmonic reducer and trace the source of the fault. In the test of the performance of the harmonic reducer, the hardware-in-the-loop simulation technology provides an effective guarantee for the test of the dynamic characteristics of the harmonic reducer. As an important part of the hardware-in-the-loop simulation, the loading devi...
