Abstract
The invention provides a method for rapidly detecting a special-shaped complex round pipe fitting, and relates to the field of aluminum alloy die casting machining. Detecting whether the special-shaped complex circular tube piece can pass or not by using a circular steel ball with the diameter of the inner diameter of the circular tube piece plus the upper limit of the dimensional tolerance; then, a round steel ball with the diameter being the lower limit of the size tolerance of the inner diameter of the round pipe is adopted to plug in from one end of the special-shaped complex round pipe; and finally, observing whether the circular steel ball can come out from the other end and smoothly return, judging that the circular pipe piece with the complex shape is qualified in size, and judging that the circular pipe piece with the complex shape is unqualified in size if the circular steel ball cannot smoothly return. By using the method for rapidly detecting the special-shaped complex round pipe fitting, which is disclosed by the invention, the round steel ball matched with the basic size and the upper and lower tolerance of the round pipe fitting is adopted, so that whether the effective sectional area in the special-shaped complex round pipe fitting meets the requirement of the dimensional tolerance can be rapidly and accurately detected, and the detection efficiency and the detection accuracy are greatly improved.
Description
Technical Field
The invention relates to the field of aluminum alloy die casting machining, in particular to a method for quickly detecting a special-shaped complex round pipe fitting.
Background
The special-shaped complex circular pipe is usually formed by welding precise seamless steel pipes, and foreign matters such as welding slag and the like are frequently generated at the joint welding position to block the pipeline; as the pipe fitting is an insert in an aluminum alloy die casting of an engine reinforcing plate and is used for introducing 130 ℃ high-temperature engine oil, the inside and the outside of the pipe fitting need to be galvanized for corrosion prevention, foreign matters are accumulated in the middle of the pipe fitting in the galvanizing process, and particularly the pipe fitting with complicated special shape below phi 6 mm.
And meanwhile, the insert in the aluminum alloy die casting is made, the insert is fixed in a die before the die is closed, the insert is coated in the aluminum alloy liquid by rapid solidification under high pressure, the aluminum liquid occasionally splashes into a round pipe fitting of the insert in the high-pressure high-speed liquid filling process, and even the round pipe fitting is blocked to cause part failure in severe cases.
The method is used for detecting whether gas or water overflows from one end of the round pipe piece with complicated shape, and whether foreign matters are blocked in the pipe piece is judged by detecting whether gas or water overflows from the other end of the round pipe piece.
Disclosure of Invention
The invention provides a method for rapidly detecting a special-shaped complex round pipe fitting, which can rapidly and effectively detect whether the inside of the special-shaped complex round pipe fitting is blocked after the special-shaped complex round pipe fitting is used as an aluminum alloy die casting insert and simultaneously detect whether the whole section of the effective diameter of the inside of the original insert meets the dimensional tolerance.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a method for rapidly detecting a special-shaped complex round pipe fitting comprises the following steps:
1) firstly, detecting whether a special-shaped complex circular tube piece can pass by using a circular steel ball with the diameter of the inner diameter of the circular tube piece plus the upper limit of the dimensional tolerance;
2) then, a round steel ball with the diameter being the lower limit of the size tolerance of the inner diameter of the round pipe is adopted to plug in from one end of the special-shaped complex round pipe;
3) and finally, observing whether the circular steel ball can come out from the other end and smoothly return, judging that the circular pipe piece with the complex shape is qualified in size, and judging that the circular pipe piece with the complex shape is unqualified in size if the circular steel ball cannot smoothly return.
The invention has the beneficial effects that:
by using the method for rapidly detecting the special-shaped complex round pipe fitting, which is disclosed by the invention, the round steel ball matched with the basic size and the upper and lower tolerance of the round pipe fitting is adopted, so that whether the effective sectional area in the special-shaped complex round pipe fitting meets the requirement of the dimensional tolerance can be rapidly and accurately detected, and the detection efficiency and the detection accuracy are greatly improved.
