Tool for machining circular hole in oblique plane and machining method of tool

Abstract

The invention discloses a tool for machining a circular hole in an oblique plane. The tool comprises a cushion block, a holding mechanism, a first drill bit and a second drill bit, wherein the cushion block is fixed on a machining oblique plane; the holding mechanism is used for fixing the cushion block with the machining oblique plane together; the first drill bit and the second drill bit are used for machining the circular hole. The invention further provides a machining method of the tool for machining the circular hole in the oblique plane. According to the machining method, the circular hole is machined twice by virtue of the two drill bits, respectively. According to the tool and the method, deficiencies in the prior art can be overcome, and the machining quality of the circular hole in the oblique plane can be improved.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a tool for machining round holes on an inclined surface and a machining method thereof. Background technique [0002] During the processing of various parts, it is often necessary to process round holes on inclined surfaces. Since the round hole is processed on the inclined surface, the contact angle between the drill bit and the processing surface is not a right angle, which affects the normal feed of the drill bit. In the prior art, various processing fixtures are usually used to support and protect the processing parts, thereby improving the stability of the drill bit during rotary drilling. However, due to the non-perpendicular contact between the drill bit and the machining slope, the drill bit will produce uneven extrusion and damage to the edge of the round hole, which will affect the processing quality of the round hole. Chinese invention patent CN 101745662B disclose...

However, due to the non-vertical contact between the drill bit and the processing inclined surface, the drill bit will produce uneven extrusion and damage to the edge of the round hole, which will affect the processing quality of the round hole

Chinese invention patent CN 101745662B discloses a processing method for inclined holes. An end face perpendicular to the feed direction is processed on the processing surface, thereby improving the processing accuracy. However, this processing method requires separate end processing of the workpiece. , needs to be processed by a separate milling machine. In order to ensure the processing quality of the end face, the processing time is long, resulting in a long time for processing the round hole on the inclined surface, and the processing efficiency cannot be further improved.
