Description

Machining method of high-precision and difficult-to-position three-way pipe
Technical Field
The invention relates to a method for processing a three-way pipe part with high precision and difficult positioning.
Background
For an enterprise without a three-axis lathe, it is not economical to add new equipment if it is temporarily subjected to the task of machining a high-precision, difficult-to-position tee fitting as shown in fig. 1. The surface precision requirement of the three-way pipe part is high, if a three-axis milling machine is adopted for processing, because the feeding direction of the milling cutter is parallel to the direction of the conical wall of the part during processing, scales are formed on the surface of the part and the requirement is not met; and if a two-axis lathe is adopted for processing, the requirement of the two-axis lathe cannot be met due to high requirements on symmetry and coaxiality.
The three-axis milling machine has excellent functions of positioning and reference finding, has a reasonable processing capacity when processing a cylindrical surface, but cannot ensure higher roughness precision when processing a conical surface; the two-axis lathe exhibits excellent machining ability in machining a conical surface, but exhibits weak ability in positioning and referencing. The part of the invention not only has the conical surface, but also needs to be accurately positioned and found to be a reference to finish the processing, so that the production task can not be finished by singly using a two-axis lathe or a three-axis milling machine.
Disclosure of Invention
The invention aims to solve the problems and the technical problems of the prior art that a three-way pipe with high precision and difficult positioning is processed by adopting a two-axis lathe or a three-axis milling machine.
A processing method of a three-way pipe with high precision and difficult positioning comprises the following steps:
(1) material picking: receiving the blank;
(2) first milling: positioning and finding a reference according to the central line, and milling a cylindrical surface-shaped processing reference, namely a left symmetrical lug and a right symmetrical lug by using a three-axis milling machine;
(3) a first vehicle: according to the reference milled in the step (2), turning the conical surfaces of the two symmetrical lugs by using a two-axis lathe;
(4) and (5) second milling: positioning and finding a reference according to the central line, and milling a cylindrical surface-shaped processing reference, namely a middle lug, by using a three-axis milling machine;
(5) the second vehicle: according to the reference milled in the step (4), turning a conical surface of the middle lug by using a biaxial lathe;
(6) and (3) milling: and milling an inner hole and a chamfer angle by using a three-axis milling machine to finish machining.
Adopt above-mentioned technical scheme's beneficial effect:
the invention completes the processing by matching the two-axis lathe and the three-axis milling machine, firstly completes the positioning, the reference finding and the cylindrical surface shape processing reference by the three-axis milling machine so as to provide the reference for the subsequent processing of the two-axis lathe, and then completes the processing of the conical surface by the two-axis lathe, thereby solving the problem of equipment limitation; practice proves that the technological process of the invention is reasonable and feasible, and the product produced by the technological process can meet the requirements.
