Embodiment Construction

[0031] Such as figure 1 and figure 2 As shown, the titanium alloy is countersinking with double-sided angle, the cutter body is fixed on the cutter body with pins, and the blade is installed on the cutter body. The specific processing method is as follows:

[0032] 1) Cutting material: select materials according to the size of the cutter body, each end of which is lengthened by 20-30mm, and the diameter of the front-end extension part is 1-2mm larger than the diameter of the inner hole of the double-sided angle countersink drill, and the diameter of the rear-end extension part The diameter of the inner hole is 1-2mm smaller than that of the double-sided angle countersink;

[0033] 2) Turning shape: fix the extended part and the cutter body on the lathe, leave 0.6-0.7mm for the outer circle according to the size requirements, and turn the angled surface;

[0034] 3) The cutting edge of the knife body reaches the size requirement, and the extended part of the knife body is ex...

Abstract

The invention provides a machining method of a two-sided angle counter bit for titanium alloy. According to the two-sided angle counter bit for the titanium alloy, a cutter body is arranged on a cutter bar and is fixed by a pin; and a cutter blade is arranged on the cutter body. The machining method comprises the following steps of: blanking; turning the appearance of the counter bit; grinding the edge part of the cutter body to a required size, and polishing the lengthened part of the cutter body; boring a pin hole on the cutter body to a required size; matching a milling cutter groove according to the grinded cutter blade; milling the cutter body to be tooth-shaped; turning off the lengthened part on the cutter body; turning an inner hole of the cutter body; blowing the cutter body and the cutter blade; welding the cutter blade on the cutter body; grinding a front angle of an angle surface; milling the inner hole to a required size; matching a tyre rod according to a map; grinding the outer circle of the cutter body to a required size; grinding a back angle of the angle surface; and assembling the cutter body and a cutter rod to finish the machining process. The machining method solves the problem that the clamping cannot be performed in turning and milling, improves the capability of the two-sided angle counter bit for the titanium alloy, enhances the production efficiency, and greatly reduces waste products.

Description

technical field [0001] The invention relates to a processing method for a countersink, in particular to a processing method for a double-sided angle countersink for a titanium alloy. Background technique [0002] In mechanical processing, for hole processing tools, there are mainly drills, countersinks, reamers, etc., but for the aviation field, it is often necessary to process parts made of titanium alloy materials. Due to the characteristics of the processed materials, the processing of the tools used is determined. It is different from the production of parts in other industries. Because the holes processed in the aviation field have high precision requirements, complex profiles, and large and small hole sizes, there are various types of tools used, and the processing is also difficult. Now Aiming at the processing method of double-sided angle countersinking for titanium alloy, the processing characteristics of this type of tool are briefly described. [0003] Difficulty...
