Abstract

The invention relates to a six-dimensional force measuring device and method based on viscous-elastic material polishing, and belongs to the technical field of ultraprecision machining and complex optical element machining and measurement and control. A polishing head with a viscous-elastic material layer is mounted in a clamp spring, the clamp spring is mounted in a groove in the front end of an elastic main body, the clamp spring makes attached contact with the inner wall of the groove in the front end of the elastic main body, and an internal thread fastening cap is connected to the front end of the elastic main body through a thread; force sensing devices in parallel connection are preloaded to the elastic main body and clamped into grooves distributed in the periphery of the elastic main body in a square shape; and an outer sleeve and the elastic main body are connected through sleeve preloaded screws, a lower cap and the elastic main body are connected through lower cap preloaded screws, and a transmission part is suspended in an expectant closed space formed by the lower cap, a contact ring and the outer sleeve. The six-dimensional force measuring device has the advantages that online precision measurement can be achieved, the coupling degree is small, the transverse force interference is small, six-dimensional force can be accurately and precisely measured in real time, and mounting and dismounting are convenient.

Description

technical field [0001] The invention belongs to the technical field of ultra-precision machining and processing measurement and control of complex optical parts, and in particular relates to a six-dimensional force measuring device and a measuring method based on viscoelastic polishing. Background technique [0002] With the advancement of modern science and technology, the machining industry has higher and higher requirements for the surface accuracy of the processed parts, and continuously improves the requirements for the measurement accuracy of the machining process. Due to the complex and changeable micro-geometric profile of the surface of the processed part and the interference of external factors during the polishing process, the polishing force will fluctuate during the processing and deviate from the theoretical calculation value. Therefore, more and more researchers and scholars are committed to It aims to improve the machining accuracy of the grinding and polishi...
