Abstract

The invention discloses a chamfering knife for double faces of a through hole. The chamfering knife is composed of a knife handle (1), a knife bar body (2), two blades (3) and an elastic closing groove (4), wherein an in-hole guide body (5) is arranged at the front end of the knife bar body (2); the surface of the in-hole guide body (5) is set as an inclined surface; the outer diameter of the in-hole guide body (5) corresponds to the inner hole of a machined workpiece; the elastic closing groove (4) is formed in the center of the interior of the knife bar body (2); the two blades (3) symmetric to each other are arranged outside the knife bar body (2) in a sleeving manner; when the in-hole guide body (5) enters the inner hole of the machined workpiece, the blades (3) enter the inner hole of the machined workpiece and chamfer and de-bur the hole surface of the inner hole of the machined workpiece by virtue of the own elastic strength of the knife bar body (2).

Description

technical field [0001] The invention relates to a double-sided chamfering knife for a through hole. Background technique [0002] The double sides of the inner hole that cannot be completed in the tool in the traditional mechanical manufacturing, especially the chamfering and deburring of the small hole wall. , the scope of use is greatly reduced. Contents of the invention [0003] The invention provides a double-sided chamfering knife for a through hole, which is not only convenient for clamping, but also can complete the processing of both sides of the inner hole. [0004] The present invention adopts the following technical solutions: a through-hole double-sided chamfering knife, which is composed of a handle, a knife body, a blade and an elastic closed groove. The front end of the knife body is provided with a hole guide, and the hole guide The surface of the tool body is set as a bevel, and the outer diameter of the hole guide corresponds to the inner hole of the wo...
