Embodiment Construction

[0018] Embodiments of the present invention will be described below according to the accompanying drawings.

[0019] Taking the modified toroidal worm pair as an example, the relevant parameters are: number of right-handed toroidal worm heads z 1 =1, the number of worm gear teeth z 2 =40, meshing center distance a=250mm, transmission ratio i=40, worm gear end face modulus m t =10.45mm, main base circle diameter d b =158mm, worm working length L w =130mm, turntable angle φ d The value range of 0~0.8rad.

[0020] image 3 It is the structural diagram of the toroidal worm turning and grinding compound machine tool based on the turning center. The toroidal worm turning and grinding compound machine tool based on the turning center includes: the bed (1), the turning longitudinal slide plate (2) and the turning transverse slide of the turning center Plate (3), tool holder (4), turning tool (5), chuck (6), torus worm (7), worm axis (8), grinding longitudinal slide (9) and grind...

Abstract

The invention relates to the field of hourglass worm machining and discloses a hourglass worm turning and grinding complex machine tool based on a turning center. A C axis is established on the center line of a chuck, an X1 axis is established on a transverse turning slide carriage, a Z1 axis is established on a longitudinal turning slide carriage, the X1 axis, the Z1 axis and the C axis are in linkage, and a spiral groove of a hourglass worm is turned. An X2 axis is established on a transverse grinding slide carriage, a Z2 axis is established on a longitudinal grinding slide carriage, a B axis is established on a rotary table, the B axis and the C axis are in linkage, and a toothed face of the hourglass worm is ground. By the adoption of the hourglass worm turning and grinding complex machine tool, the two processes of turning and grinding of the hourglass worm are finished through one-time clamping, repeated localization is avoided, and the machining accuracy is improved.

Description

technical field [0001] The invention relates to a toroidal worm turning and grinding compound machine tool based on a turning center, belonging to the technical field of toroidal worm machining. Background technique [0002] Compared with the cylindrical worm drive, the toroidal worm drive has strong bearing capacity, small size, high transmission efficiency and long service life. The double-enveloping toroidal worm drive with plane and double-cone surfaces has better performance than the straight-profile toroidal worm drive. Therefore, it is of great significance to study the machining of the helical surface of the toroidal worm. At present, the processing method of the enveloping torus worm helicoid is usually divided into two steps: the first step is to turn the torus worm helical groove according to the turning method of the straight profile torus worm helicoid on the CNC lathe with C axis, the second The first step is to grind various toroidal worm helical surfaces wit...
