Numerical control gear hobbing control method for gear repairing

Abstract

The invention provides a numerical control gear hobbing control method for gear repairing. The gear hobbing manner is used for repairing a gear with non-ideal surface roughness and precision, and therefore the gear reaches the machining requirement. Repeated tool setting is used for obtaining a reference point position, the ideal zero positions of all shafts are determined, and then a synchronous compensation algorithm is adopted to carry out hobbing on the gear to be repaired again; and the follow-up property of the shafts is improved, the machining process is more stable, the machining precision and the surface roughness are effectively improved, and the gear repairing aim is achieved. The problem that in the gear hobbing process, after a workpiece is disassembled, positioning cannot be carried out again is solved, the synchronous compensation algorithm is adopted to carry out hobbing on the gear to be repaired again, and as for the occasion with the non-specially-severe gear precision requirement, compared with traditional gear repairing methods of gear shaving, gear grinding and the like, the numerical control gear hobbing control method has the beneficial effects that the machining precision is met, meanwhile, the machining efficiency is greatly improved, and the repairing cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of numerical control hobbing control, in particular to a numerical control hobbing processing control method for gear repair. Precise zero point positioning of the gear to be repaired, and then the synchronous compensation algorithm is used to continuously correct the command position of each linkage axis, and the workpiece is hobbed again to achieve the purpose of gear repair. Background technique [0002] With the continuous improvement of industrial production level, higher requirements have been put forward for the precision of standard parts such as gears, and the importance of gear repair has become increasingly prominent. At present, the main methods used in gear repair are shaving and grinding, but hobbing, which plays an important role in gear processing, has not been applied to this field, mainly because it is difficult to reposition the removed gear after reinstallation. For secondary hobbing, even if the ...
