Problems solved by technology

[0006] Since lubricating fluid and cooling fluid are required in machining, and a large amount of chips will be generated during cutting, the gap between the driving gear and the meshing surface of the arc-shaped gear, as well as between the support of the rotary slider and the fixed base of the turntable Surfaces are polluted by a large amount of lubricating fluid, powder in cooling fluid, and chips, resulting in increased wear and a serious decrease in motion accuracy between relatively moving surfaces, thereby affecting the machining accuracy of the workpiece and the working life of the moving parts

Abstract

The invention discloses a machine tool rotary working table. A protecting hood is arranged among a rotary table facet (11), a surface and an upper surface of a fixed base (13) of the rotary table. On the section of the axis of the rotary table facet (11), the protecting hood opens downwards in the shape of inverted 'U' to form a concave-up cavity in which a driving gear (7), an arc gear (8) and a rotating sliding block (10) are all contained. By adopting the technical proposal, the precision moving elements of the rotary working table have better protecting effect, the processing precision of the machine is higher and the service life of the machine tool is longer, and the time and expenses spent in repairing or replacing precision elements are reduced.

Description

technical field [0001] The invention belongs to the technical field of machining machine tools, and relates to a feed mechanism of the machine tool. More specifically, the invention relates to a rotary table of the machine tool. Background technique [0002] In the current prior art, the rotary table of a machine tool with a larger diameter is provided with a coaxially connected rotary table fixed base and a rotary table. The axis of the rotary table coincides with the axis of the rotary table fixed base. Thrust bearing connection. The rotary table is supported on the fixed base of the rotary table by means of the rotating slider. [0003] The drive mode adopted by the rotary table is: [0004] A deceleration mechanism fastened to it is provided under the revolving table. The deceleration mechanism is driven by a motor, and a drive gear is provided on the output shaft of the deceleration mechanism; an arc-shaped gear is provided on the fixed base of the revolving table, wh...
