Abstract

The invention provides an adjustable precise boring cutter, and belongs to the technical field of boring. The adjustable precise boring cutter is characterized by composing a cutter handle, a cutter rod and a blade; an eccentric hole is formed in the cutter handle, the eccentric distance exists between the axis of the eccentric hole and the axis of the cutter handle, the axis of the eccentric hole is parallel to the axis of the cutter handle, a fastening hole vertically communicated to the eccentric hole is formed in the cutter handle, and a locking bolt is installed in the fastening hole; the cutter rod is installed in the eccentric hole, the locking bolt abuts against the cutter rod, and an installing groove in formed in the end of the cutter rod; and the blade is installed in the installing groove, and a cutter tip of the blade protrudes out of the cutter rod. The adjustable precise boring cutter has the beneficial effects of being convenient to adjust and high in precision.

Description

technical field [0001] The invention belongs to the technical field of boring and relates to a boring cutter, in particular to an adjustable precision boring cutter. Background technique [0002] Chinese patent CN103028747A discloses a super-hard tungsten carbide deep hole shock-resistant internal cooling adjustable boring tool, including: a hard alloy cutter bar, connected with the scale end of the eccentric sleeve with scale through a screw, and the other end of the eccentric sleeve with scale One end is connected with a non-standard side fixed tool holder, and the diameter of the eccentric sleeve with scale can be adjusted. [0003] The above-mentioned adjustable boring tool is connected with an eccentric sleeve in the adjustment tool rod, and the eccentric sleeve is connected with the tool handle. The number of connecting parts in the middle is increased, which will easily increase the cumulative error, reduce the adjustment accuracy of the boring tool, and shorten the s...
