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.

Abstract: A system for machining and positioning an automobile hub and a production line for intelligent cleaning and precision including upper and lower mounting plates connected vertically. At least three U-shaped blocks are fixed on a top surface of the upper plate. An L-shaped support is mounted between every two blocks including a screw-equipped ball head disposed thereon. The support is driven by a first driving apparatus to move along the upper mounting plate. A slidable chuck is disposed in each block, with a push rod assembly connected to the bottom. The assembly is driven by a second driving apparatus to move along the upper mounting plate with the chuck. Three wedges are circumferentially fixed on a top surface of the lower plate and are driven by a third driving apparatus to move along the lower plate. Inclined surfaces of the wedges are mated with bottoms of the push rod assemblies.

Abstract: An automobile hub fixture includes a fixture body and a positioning apparatus. The fixture body includes a fixed platform and a plurality of clamping claws arranged at intervals in a circumferential direction of the fixed platform. The clamping claws are configured to clamp an outer rim of a hub. The plurality of clamping claws are connected to a driving member by using a linkage, and the driving member drives the clamping claws to radially move along the fixed platform. The positioning apparatus includes a movable platform slidably connected to the clamping claws. A positioning module configured to position an inner rim or the outer rim of the hub is mounted to the movable platform. The machining device includes a fixture, a machine tool, and a minimal quantity lubrication apparatus. The production line includes a machining device, a loading system, a loading and unloading manipulator, and a catching table.
