Planetary wheel numerical control polishing removal function generator

Abstract

The invention discloses a planetary wheel numerical control polishing removal function generator, which comprises a revolution shaft system, a rotation shaft system, a polishing disk, an eccentric adjusting mechanism and a slewing mechanism. The revolution shaft system is connected above the eccentric adjusting mechanism; the slewing mechanism is connected to the bottom end of the eccentric adjusting mechanism; the rotation shaft system is connected below the slewing mechanism; the polishing disk is arranged at the lower end of the rotation shaft system; the rotation shaft system comprises a rotation shaft, a rotation motor, a rotation transmission mechanism and a rotation shaft base; the rotation shaft base is connected to the slewing mechanism; the rotation shaft is arranged in the rotation shaft base; the rotation motor is fixed to the rotation shaft base; and the output end of the rotation motor is connected with the rotation shaft through the rotation transmission mechanism. The planetary wheel numerical control polishing removal function generator has the advantages of high rigidity for the transmission of the rotation shaft system, balanced rotation and capability of acquiring stable removal functions.

Description

technical field [0001] The invention relates to the technical field of optical precision machinery, in particular to a planetary wheel type numerically controlled lapping and removing function generating device. Background technique [0002] Since the 1970s, with the rapid development of computer technology and the surge in demand for medium and large-caliber, high-precision aspheric optical components worldwide, a group of domestic and foreign research institutes led by Itek Corporation of the United States have computer-controlled optical surface forming. Technology (CCOS) is introduced into the ultra-precision machining of medium and large-diameter aspheric optical parts to improve the processing efficiency and precision of aspheric optical components. CCOS technology refers to the use of a polishing disc much smaller than the workpiece, under the control of the computer, to move on the surface of the optical part at a specific path and speed, by controlling the residence...

Problems solved by technology

However, the transmission of the flexible shaft is not stable and the transmission rigidity is poor, which limits the improvement of machining accuracy.

[0007] Judging from the above-mentioned publicly reported literature, the current grinding and polishing removal function generator has the defects of low processing efficiency or insufficient smooth transmission, which limits the efficiency and stability of the removal function.
