The hemispherical pneumatic grinding wheel electrostatic sand-planting system has the beneficial effects that the abrasive particles on the surface layer of the hemispherical grinding wheel are distributed uniformly, so that the defect that original electrostatic sand-planting equipment can only be used for realizing consolation of a planar substrate; a digital image processing method is adopted to perform real-time detection on the abrasive particles on the surface layer of the hemispherical grinding wheel.

Description

technical field [0001] The invention relates to a hemispherical pneumatic grinding wheel electrostatic sand planting system with abrasive detection. Background technique [0002] The soft consolidated abrasive grain pneumatic grinding wheel has a hemispherical structure and is divided into two layers. The inner layer is composed of elastic composite materials to form a rubber matrix layer, forming a hemispherical airtight space. By controlling the air pressure, the grinding wheel has flexible characteristics, which is convenient for the processing of free-form surfaces; the outer layer is composed of abrasive grains mixed with a binder. Under the action of the binder, macroscopically, the grinding wheel maintains a consistent motion state, and microscopically, there is also local fretting, which forms mutual extrusion between abrasive grains during processing, thereby increasing the processing stress. Pneumatic grinding wheels combined with robots can realize efficient auto...
