Two-dimensional ultrasonic vibration polishing device for optical curved surface machining

Abstract

The invention discloses a two-dimensional ultrasonic vibration polishing device for optical curved surface machining. The two-dimensional ultrasonic vibration polishing device comprises a machining base; an upper connecting main frame which is vertically fixed on the upper end surface of the processing base; a deviation adjusting clamping assembly which is arranged in the middle of the upper end face of the machining base, wherein the deviation adjusting clamping assembly is used for positioning and clamping a machined workpiece and can adjust the track of the machined workpiece at the same time; fixed guide rails which are vertically and symmetrically erected on the two sides of the upper connecting main frame; a bearing seat which is arranged on the fixed guide rail in a relatively sliding and limiting manner, and is vertically driven to slide by a transmission chain plate arranged in the upper connecting main frame; a curved surface adjusting and polishing assembly which is arranged in the middle of the bearing base and located over the deviation adjusting and clamping assembly. and drainage wheel sets which are symmetrically erected on the two sides of the upper end face of the machining base in a relatively rotating mode; a dust collection cover is fixed to one end of each drainage wheel set, and the other end of each drainage wheel set communicates with an outer drainage pipe.
