Abstract

The invention discloses a deburring tool for square crossing hole intersecting contour lines, which includes a cylindric tool bit and a tool bar, wherein three blades are integrally arranged on the tool bit, and are equal-distantly arrayed around the rotating shaft of each tool bit in a fan-shaped manner; a cutting angle alpha and a notching angle beta are integrally formed in the corresponding adjacent two blades of each blade groove; the cutting angle alpha is vertical to the axial direction of the tool bit and inclines and extends outwards. According to the invention, the structure is simple and practical, the working efficiency is high, a rotary ball-shaped tool is additionally arranged for deburring in advance, so that the parts intersecting lines have burrs stable in size, position and shape, a good foundation is laid for follow-up ECM, and tests prove that the effect of deburring operation in advance is good.

Description

technical field [0001] The invention relates to a deburring tool for auto parts, in particular to a deburring tool vertically intersecting contour lines of intersecting holes. Background technique [0002] The shape of a mechanical part is often formed by combining two or more basic solids in different ways. The intersection of two solids when combined is called two solids intersecting, and the intersection line formed on their surfaces is called intersecting line; deburring is to remove The harmfulness of burrs is particularly obvious in the thorns or flashes formed at the intersection of parts and surfaces, and is gradually attracting people's attention. [0003] In the high-pressure fuel rail fittings of automobiles, there are usually two sets of intersecting contour lines formed by non-orthogonal holes with different diameters. After machining, burrs will remain. The burrs there are random, large and small, and the position Not fixed, causing difficulties for subsequent...
