Abstract
The invention provides a dual-lead and dual-index worm hobbing machine workbench. A front worm bracket and a rear worm bracket are installed on the front portion and the rear portion of a base correspondingly. A front double-pitch index worm and a rear double-pitch index worm parallel to the front double-pitch index worm are installed on the front worm bracket and the rear worm bracket correspondingly. The input end of the front double-pitch index worm and the input end of the rear double-pitch index worm are connected with an output shaft of a reduction box through three pairs of spiral bevel gears. An input shaft of the reduction box is connected to a servo motor or an output shaft of an index change gear box. According to the dual-lead and dual-index worm hobbing machine workbench, the backlash of a worm gear pair can be adjusted through axial adjustment of the dual-pitch index worms, in this way, the defect that after an original worm gear pair is abraded due to working, the theoretical center distance of the worm gear pair is decreased can be effectively overcome, and thus the indexing precision of the workbench is improved. The structure is simple, and implementation is easy. By the adoption of a double-worm structure, the torque of the workbench is uniform, transmission is stable, and the workbench is prevented from shaking when a large-modulus workpiece is machined.
