Embodiment Construction

[0021] The present invention will be further described in conjunction with accompanying drawing:

[0022] Such as figure 1 As shown, the active compliance polishing device for viscoelastic materials of the present invention is composed of marble slab 7, support beam 3, ultrasonic vibration system 4, laser displacement sensor, pneumatic guide rail in XYZ direction, workbench 12 and other parts.

[0023] The workpiece is stuck in the center of the table 12, and the requirements for processing complex curved surfaces are met by adjusting the poses of the oscillating table 10 and the rotating table 11 below the table 12. The motors 5 on both sides of the base 6 of the oscillating table 10 and the rotating table 11 are driven .

[0024] The X-direction air bearing guide rail 8 realizes the X-direction stroke feed of the workpiece, and the Y-direction stroke feed of the workpiece is precisely controlled by the double parallel axis Y-direction air bearing guide rail 9, and the air b...

Abstract

The invention discloses an initiative mild grinding and polishing device and a method based on a viscous-elastic material, and mainly solves such problems as nonuniform removing quantity, imprecious positioning of a polishing head, mismatching between the shape of a polishing tool and the surface of a workpiece and generation of errors by vibration of the workpiece in the polishing process. The device consists of such several parts as an ultrasonic generation part, a laser displacement sensor detecting part, a viscous-elastic material polishing part and a worktable. The device machines an optical free curved surface, needs no frequent adjustment of the cutter position for the surface of a part with a more complex curved surface, adjusts the force application frequency to change the shape of the viscous-elastic polishing head so as to always keep a gapless bonding state between the viscous-elastic grinding and polishing head and the surface of the workpiece in the machining process, and realizes initiative mild grinding and polishing of the workpiece.

Description

technical field [0001] The invention belongs to the technical field of workpiece surface finishing polishing and processing, in particular to an active and smooth polishing method and device based on viscoelastic materials, which are suitable for ultra-precision processing of optical free-form surfaces. Background technique [0002] With the continuous development of technology, optical free-form surface parts are widely used in all walks of life. Traditional polishing technology and various computer technologies developed can no longer meet the processing requirements of high-precision and complex optical surfaces. Surface quality and surface shape Accuracy and other issues need to be solved urgently; in the traditional grinding and polishing process, the polishing tool head cannot achieve a seamless fit with the surface of the workpiece, and the workpiece will produce errors due to machining vibration during ultrasonic vibration grinding and polishing, and the machining acc...
