Numerical control five-axle linkage planar double enveloping worm cyclone cutting machine tool

Abstract

The invention discloses a digital control five-axis three-linkage enveloping worm whirlwind stock-removing machine which mainly consists of a lathe bed, a cross slide, a tailstock, a spindle, and a vertical planker; a turning mechanism is arranged on the cross slide; a whirlwind tool rest is installed on the turning mechanism; a cutter head is installed on the whirlwind tool rest; a plurality of cutting knifes are symmetrically installed on the cutter head; the central rotation axis of the spindle is an X axis; the central rotation axis of the turning mechanism is a Y axis; a horizontal kinematic axis of the cross slide is a Z axis; the central rotation axis of the cutter head is an A axis; the rotating shafts of a cutter head mounting bracket and a motor mounting bracket on the whirlwind tool rest are a B axis; the machine tool has the movement along the five axis-A, B, X, Y, Z; and linkage function can be realized along the directions of the three axis-X, Y, and Z; by controlling of the movement of the cutting edge of the cutting knife, a planar enveloping hourglass worm gear surface can be processed out. The digital control five-axis three-linkage enveloping worm whirlwind stock-removing machine has the advantages of processing the enveloping worm rapidly with high precision under high speed cutting state; and the production efficiency can be greatly improved.

Description

technical field [0001] The invention relates to a mechanical processing machine tool, in particular to a numerically controlled five-axis three-linkage plane enveloping torus worm cyclone cutting machine tool. Background technique [0002] Among the existing planar enveloping toroidal worm processing equipment, it is mainly formed by grinding. Its advantage is that the helical surface of the planar enveloping toroidal worm can be precisely formed at one time, and the precision of the processed workpiece is high, but its disadvantage is the production efficiency. Low cost, it takes 2 to 3 hours to process a toroidal worm, which is expensive, resulting in high cost of the workpiece to be processed, and the processing machine is huge, it is impossible to process small toroidal worms with a center distance less than 125mm, which limits the toroidal worm production applications. [0003] The Chinese invention patent application with the publication number CN1493427 discloses a p...
