Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an axis positioning and rotating device for visual detection of multi-link type helical gears. Background Art

[0002] A field survey of gear production and processing factories found that common surface defects of gears before leaving the factory include bumps and grinding burns. Bumps are usually caused by collisions between gears and surrounding objects or between gears during transportation.

[0003] Therefore, when inspecting the helical gears, due to the cylindrical characteristics of the gears themselves, the human eye needs to walk around the gears and observe them while walking to achieve all-round observation of the gears, which wastes manpower.

[0004] Therefore, it is necessary to design a helical gear fixture based on visual inspection, which can adapt to different gear diameters to complete centering. When the visual inspection component takes a surround shot of the helical tooth surface of the helical gear, the axis of the helical gear remains stationary, thereby meeting the inspection requirements.
