Abstract: A machining and positioning system for aerospace irregular parts and a discrete intelligent production line therefor are provided, which relates to the field of aerospace irregular part machining. In view of the problem that complex repeated positioning and poor positioning stability is required during the transportation and processing of aerospace irregular parts, a self-positioning device, a clamping device, and a support device are used to form a follow-up clamping and positioning system for the irregular part casing, reducing complex repeated positioning. The support block of the support device can fit to the inner wall of the casing, collect the support force using piezoelectric plates, and feedback and adjust the thrust of the support block based on the magnitude of the cutting radial force, maintaining stable support of the support block for the casing and meeting production needs.

Abstract: Provided in the present invention are a dynamic collection device for an oil film and temperature distribution in a grinding zone and an operating method thereof. A spectroscope and a 45-degree flat mirror are utilized to carry out optical imaging of the permeation and infiltration of the grinding fluid in a grinding zone during a grinding process, and a video signal imported into a high-speed camera is converted into a digital signal processed by a CCD photosensitive element, and a dynamic image is imported for dynamic collection. Infrared radiation emitted from the grinding zone is reflected through the 45-degree flat mirror, and transmitted to the thermal imaging camera, and the signal is transmitted to an internal infrared detector. The infrared detector adjusts and amplifies the received signal and outputs it to an infrared thermal imaging chip. After image processing, the temperature distribution image is imported for dynamic collection.
