Abstract

The invention provides a honing method and device based on visual positioning. The honing method based on visual positioning comprises the following steps of collecting an image of a to-be-honed holein a workpiece to be ground by using visual recognition equipment; processing the image, and obtaining position information of the center of the to-be-honed hole; based on the position information, adjusting the position of the workpiece to be ground to enable the hole position of the to-be-honed hole to be coaxial with a honing head of honing processing equipment; and inserting the honing head into the to-be-honed hole, and vertically moving the honing head to perform honing processing on the to-be-honed hole. The honing method and device based on visual positioning provided by the inventionhave the advantages that the center position of the to-be-honed hole can be accurately positioned; the honing precision and stability are improved; during image collection, the center position of to-be-honed hole can be positioned only by presetting the approximate position of the workpiece to be ground, then, the automatic positioning and processing are completed; great processing and clamping errors of the workpiece to be ground can be allowed; in addition, the coaxiality of the honing head and the to-be-honed hole can be ensured; and the honing precision during great-batch processing is greatly improved.

Description

technical field

[0001] The invention belongs to the technical field of honing processing, in particular to a honing method and device based on vision positioning. Background technique

[0002] Honing is the finishing process of the finished surface with the oil stone (also called honing bar) embedded in the honing head. It is mainly used for aperture grinding of honed workpieces in manufacturing industries such as automobiles, tractors, hydraulic parts, bearings, and aviation. , during honing, the workpiece is installed on the honing machine table or in the fixture, and the honing head with a number of honing stones is inserted into the processed hole, driven by the main shaft of the machine tool to rotate and reciprocate in the axial direction, and the honing stone is pressed against the hole wall with a certain pressure. Contact can cut off a very thin layer of metal.

[0003] Hole honing is an efficient processing method with high precision, high surface quality, and lar...
