Hourglass worm turning and grinding complex machine tool based on turning center

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...

Problems solved by technology

In the patent of the People's Republic of China with the application number 201010609380.0 "a four-link toroidal worm CNC turning and grinding compound machine tool and its processing method", it is described that turning and grinding the torus worm helical surface on a CNC lathe with a C axis method, but in this method, the two processes are carried out on the same lathe. After the turning process is completed, the CNC tool holder and the bottom plate need to be removed, and the grinding head can be installed to carry out the grinding process. The efficiency is low.
