The bull eyeball is additionally arranged, the bull eyeball is used as an acting point, the front end of the cutter row is supported in the boring process, and the rigidity of the cutter row is improved; in addition, in the boring process, the eyeball rolls on the inner wall of the hole bored by the part, and the required roughness is rolled.
Description
Technical Field
The utility model relates to a machining, concretely relates to bore hole frock is assisted to overlength bucket spare part.
Background
For machining holes on ultra-long barrel parts, the length of the hole which is formed by extending the cutter row to the effective length according to the requirement is determined, and the length of the hole can reach one meter, eight meters and two meters, so that the rigidity of the cutter row is insufficient, and the phenomenon of cutter stuffiness is easy to occur in the boring process, thus leading to cutter explosion and waste production.
Disclosure of Invention
In order to solve the problem, the utility model provides an auxiliary boring tool for an overlong barrel part, which aims to improve the rigidity of a cutter row.
The technical scheme of the utility model:
an auxiliary boring tool for a part of an overlong barrel part is characterized in that a boring cutter is arranged at the front end of a cutter row of a boring machine tool, a part is arranged on the boring machine tool, the boring cutter moves back and forth along with the cutter row of the boring machine tool and moves relative to the part, the part rotates, and the boring cutter are matched for boring; the auxiliary boring tool is a bull eye, the bull eye is installed at the front end of a tool block of the boring machine tool and is positioned behind the boring tool;
in the boring process, the eyeball abuts against the inner wall of the hole in the part to serve as an acting point, the front end of the cutter bar of the boring machine tool is supported right below the front end of the cutter bar of the boring machine tool, the cutter bar of the boring machine tool moves back and forth and the part rotates at any time, and the eyeball rolls on the inner wall of the hole in the part.
The bull eyeball is connected with the front end of the cutter row of the boring machine tool through the screw rod, the screw rod is in threaded connection with the front end of the cutter row of the boring machine tool, the screw rod is screwed, and the height of the bull eyeball is adjusted.
The eyeball and the boring cutter are staggered by a distance of one cutter width along the cutter row direction of the boring machine tool. By the design, the cutting force of the boring cutter can not be influenced in the boring process, and the cutter can not drop down suddenly at the edge of the workpiece after the cutter leaves the workpiece, so that the edge of a hole is prevented from being damaged.
The utility model has the advantages that the design is reasonable, the structure is simple, the bull eyeball is added, the bull eyeball is used as an acting point, the front end of the cutter row is supported in the boring process, and the rigidity of the cutter row is improved; in addition, in the boring process, the eyeball rolls on the inner wall of a hole bored by the part, and the required roughness is rolled (of course, the requirement on the eyeball is higher, and for the reason, according to the cutting force formula of a machine tool:
