Problems solved by technology
[0003] Now with the continuous progress of the industrial society, the processing technology is also constantly improving, and the processing accuracy is getting higher and higher. The ordinary rotary table cannot meet the increasing processing accuracy due to its large indexing error and inaccurate zero return position. Nowadays, all kinds of machine tools and various processing equipment are more and more emphasizing the collaborative work between the processing end and the workbench

The invention discloses a high-precision rotary working table with two-stage regulation and control. The high-precision rotary working table comprises a working table, a rotary shaft, a rotary pedestal, a working table pedestal, a base and a bottom frame, wherein the rotary shaft is arranged below the working table; a control motor on the base is controlled to regulate an inclination angle of the working table; a claw-shaped pushing rod for fixing a hydraulic cylinder clamps and fixes a housing, working height of the working table is regulated by controlling a lifting hydraulic cylinder; a servo motor is controlled to rotate to drive a rotary shaft gearbox to work, to drive the wheel shaft and a drive wheel to rotate, to drive a driven wheel to rotate, to drive the rotary shaft to rotate, and to drive the working table to rotate, so that rotation of a rotary worm and gear, and a hypoid gear is controlled through fine tuning, two-stage regulation and control is realized, and indexing accuracy is improved; a connecting device is arranged between the base and the working table pedestal, and the base and the bottom frame can move up and down, so that the high-precision rotary working table can complete actions of inclining and lifting, and can be matched with processing work of the machine tool better.
Description
technical field [0001] The invention relates to a machine tool accessory, in particular to a two-stage control high-precision rotary worktable. Background technique [0002] As the name suggests, the turntable is a rotatable work platform, which is used in various fields. In machining, the turntable is indispensable. The turntable is a rotatable table for clamping workpieces and A machine tool accessory that realizes rotary and indexing positioning, especially suitable for turning and milling compound processing machine tools that can rotate tools and workpieces. The rotary table usually includes two parts: the table and the rotary body installed under the table. The clamping device is used as a rotary machine tool. An important part of the workbench, it is used to keep the workbench in a locked state after the rotary workbench is precisely positioned or indexed, thereby ensuring the machining accuracy of the workpiece. [0003] Now with the continuous progress of the indus...
