The utility model provides a
machining part for
honing an inner hole, which relates to the technical field of inner hole
machining, is used for being assembled on a cutter bar of a main shaft of a boring
machine, and comprises a seat body, one end of the elastic mechanism is connected with the seat body; the
honing oilstone is connected with the other end of the elastic mechanism; one end of the connecting rod is connected with the seat body, and the connecting rod intersects with the cutter bar and is in sliding connection with the cutter bar so as to be used for adjusting the distance between the
honing oilstone and the cutter bar; the
locking mechanism is arranged on the cutter bar, the
locking mechanism is used for locking the connecting rod on the cutter bar, and the honing oilstone can hone the hole wall of the inner hole to be machined when the main shaft rotates; the
machining part can guarantee that the hole wall roughness of the
tailstock mandrel hole meets the design requirement, meanwhile, the machining part can be suitable for machining
tailstock mandrel holes with different hole diameters, and universality is high.
