Abstract

The invention provides a numerical control double-rotation working table driven by double-globoidal cams. A first tank is fixedly arranged on the top part of a bottom plate; a rotation shaft is arranged in the center of the first tank; a first driven plate is arranged on the rotation shaft and is connected with a double-stage driving mechanism for driving the first driven plate to rotate; the double-stage driving mechanism is arranged in the tank and is connected with a first servo motor for providing power; a rotation table is arranged on the top part of the rotation shaft; a top clamping table is adjustably arranged on the top part of the rotation table through a screw rod adjusting mechanism; a workpiece rotation mechanism for driving a workpiece to rotatably index is arranged on one side of the top part of the top clamping table; and a workpiece clamping mechanism is arranged at the power output end of the workpiece rotation mechanism. The rotation working table is provided with double rotation shafts, so that double-rotation-shaft linked space surface milling processing can be realized; and by applying a double-globoidal-cam retarding mechanism, the friction loss during the use of worm-gear mesh transmission is reduced.

Description

technical field [0001] The invention relates to a numerically controlled double-rotary workbench driven by double-arc cams, which belongs to the field of machinery manufacturing equipment. Background technique [0002] The machinery and equipment manufacturing industry is the cornerstone of a country's industry. It provides important means for the development of new technologies and new products, and is an indispensable strategic industry. With the continuous and rapid development of my country's economy and the urgent need for economic transformation, the machinery manufacturing industry is inevitably moving towards high, refined and cutting-edge levels. Among them, the development of CNC machine tools is very important. The accuracy of CNC rotary table will directly affect the machining accuracy of CNC machine tools. The curved surface cam mechanism is a space cam transmission mechanism suitable for medium and high-speed mechanical equipment. The transmission mechanism ...
