A hand-held fine boring device

Abstract

The invention discloses a hand-held fine boring device, which comprises a rotating rod, a boring tool assembly detachably mounted on the rotating rod, an adjusting assembly rotatably installed in the center of the rotating rod, and a rotating assembly mounted on the adjusting assembly A number of centering components on the circumferential side wall; a linkage plate is fixed at the end of the rotating rod, and the linkage plate is mechanically connected to the motor; the adjustment component can control several centering components to be deployed synchronously to the peripheral side and resist Hold to the wall of the hole. After fixing, the adjustment assembly remains coaxial with the hole, and the rotating rod also remains coaxial with the hole under the positioning of the adjustment assembly. The rotation rod rotates around the adjustment assembly under the drive of the motor. Rotate, and drive the boring tool assembly to rotate to repair holes. The invention not only facilitates repairing and processing of holes, improves efficiency and saves manpower, but also effectively prevents out-of-circle problems during manual repairing and ensures the circumference of the holes.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a hand-held fine boring device. Background technique [0002] In the process of production and processing, hole repair processing is an extremely important processing method. Generally, the parts are fixed by the fixture tooling, and the machine tool is used to perform milling or boring processing on the parts to correct the circumference of the hole, so that zero The holes in the part meet the required dimensional accuracy. [0003] The above-mentioned machine tool processing methods are generally only applicable to parts that are not installed and fixed. For parts that have been fixed, repairing and processing holes requires removing the parts from the mold and other devices, and reinstalling them after repairing. The original position, in this process, not only the disassembly process is too complicated, but also easily affects the assembly accuracy of the devic...
