Abstract

The invention discloses a method for aligning, online detecting and correcting of a gearwheel. The method comprises the following steps that: A, alignment before processing is performed, wherein an air supporting turntable is placed on a workbench, and a bottom slipway is inflated to ensure that the air supporting turntable is suspended on the surface of the workbench, and proper alignment of theair supporting turntable and the work bench is adjusted; a workpiece is placed on an air supporting slide block, the air supporting slide block is simultaneously inflated to jack the workpiece, and afine regulating device regulates the workpiece to be coaxial with the workbench; an optical theodolite is regulated to be coaxial with the air supporting turntable to complete the alignment; B, online detection is performed, an accurate turn angle of workpiece is detected, and related gear precision and longitudinal form error are detected; and C, based on online measurement, the gear precision is improved through alignment. The method can make the gearwheel easily moved, aligned, online detected and corrected on the workbench of a machine tool through the air supporting slide block and the air supporting turntable, and obviously improve the processing precision of the gearwheel.

Description

technical field

[0001] The invention belongs to the technical field of mechanical processing equipment, and relates to a method for alignment, in-position detection and correction of large gears. Background technique

[0002] With the continuous improvement of the modern industrial level, the demand for large gears is increasing. High-precision large gear processing machine tools with automatic detection and gear grinding functions are expensive. Generally, large-scale gear processing enterprises are equipped with one or two sets at most, and more Most of them are large gear processing machine tools with ordinary machining accuracy and functions. Large gears are difficult to install and align due to their large geometric dimensions, heavy weight, large moving friction, and low adjustment resolution. This type of machine tool has the following problems in use:

[0003] It is difficult to align the workpiece. Because the diameter of the large gear is very large (generally mor...
