Description
Technical Field
The invention relates to an adjustable honing rod for blind holes.
Background
In the mechanical processing, the precision processing of the inner hole of the workpiece generally adopts honing processing, and a special honing tool and a clamp are required to be adopted on a special honing machine for processing. In the honing process, the honing tool (generally called a honing rod or a honing head) adopted at present is a rigid structure, and in order to make the grinding tool well attached to the hole wall, the honing tool needs to float or the workpiece floats or both the honing tool and the workpiece float simultaneously for honing, so that the precise processing of the hole becomes an independent difficult work with high cost, time consumption and labor consumption. Modern cutting machine tools, especially precision numerical control machine tools, mostly have the movement function of honing machines, the working precision can meet the requirements of honing process, if after the cutting process such as drilling, boring, reaming and the like is carried out on the cutting machine tools, the honing tool can be installed for honing processing, and the problem of hole precision processing is solved. According to the floating working principle of the honing process, under the working conditions that the honing tool is in standard rigid connection with a machine tool and a workpiece is rigidly mounted, the honing strip has a certain compensation function, so that the problem of the fitting property of the honing tool and the wall of the hole of the workpiece is solved.
