Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a gear precision real-time visualization device and method based on on-machine measurement of a gear grinding machine. Background technique [0002] Machining is the basic operation of advanced manufacturing technology and the most basic and active link in the advanced manufacturing system. It can guarantee the high quality of products under the condition of low cost and high productivity. One of the key technologies in the process of machining is the on-machine measurement technology of machining, which can directly measure the workpiece after processing the workpiece and give real-time feedback on the processing quality of the workpiece. The on-machine measurement technology can not only reduce the The clamping error caused by the secondary clamping can also save operating time, thereby improving the measurement efficiency. Especially under the conditions of ma...

Problems solved by technology

[0003] However, the existing on-machine measurement technology can only perform fitting calculations to obtain the final fitting image after completing all the data collection of the gear to be tested.

Therefore, the existing on-machine inspection technology has no sense of sight, cannot find the processing quality problems of the gears to be tested in time, and also wastes a lot of time on the measurement and inspection of the gears

In addition, the existing gear measurement equipment has large volume, limited measurement conditions, and high cost, so that most domestic machine tools cannot be equipped with on-machine measurement systems, so that the existing on-machine measurement technology cannot accurately fit the measurement The evaluation and optimization of software ultimately restricts the integrated process of processing and manufacturing, resulting in slow product manufacturing
