Description

Adjustable marking device and marking method for catheter part

Technical Field

The application relates to the technical field of metal conduit part manufacturing, in particular to an adjustable marking device and a marking method for a metal conduit part.

Background

At present, metal conduit is manufactured in a large number of applications in the field of aviation. The hydraulic, fuel, environmental control and oxygen systems in the aircraft are distributed with a large number of metal conduits and conduit combined parts with different shapes. The conduit combined part is formed by welding or assembling conduits with different lengths and other combined parts.

When parts are manufactured, the guide pipe is required to be blanked firstly, the blanking of the long guide pipe always leaves a margin firstly, and the margin is removed after the size of the parts is determined. The processing of the guide pipe part is divided into three steps: and (4) flattening the end face, completing equal-size scribing around the guide pipe for one circle, and removing allowance. The first step and the third step are relatively easy, the second step is difficult to realize, and no practical procedure can solve the problem of circumferential marking of the guide pipe so far, so that the difficulty is brought to the machining of guide pipe parts.

Disclosure of Invention

In order to solve the above problems, the present application provides a method of scribing a catheter part with a scribing apparatus.

An adjustable marking device for a conduit part comprises a marking ruler and a clamping seat, wherein the marking ruler comprises a fixed frame, two layers of clamping plates, a marking plate, an end face connecting plate and a clamping device; the middle of the clamping plate is provided with a sliding groove, one corner of the scribing plate is a scribing cutter head and is arranged between the two layers of clamping plates, the fixing frame is of a stool-shaped structure, two support feet of the fixing frame penetrate through the sliding grooves of the two layers of clamping plates to clamp the scribing plate in the middle of the fixing frame, end face connecting plates are respectively fixed on the left outer side surface and the right outer side surface of the two layers of clamping plates, and the clamping device fastens the two layers of clamping plates and the scribing plate into an integral structure; the clamping seat comprises two supports, a pull rod and a conduit weighing ring, a pair of conduit weighing rings is arranged at corresponding positions of the clamping seat, the outer diameter of each conduit weighing ring is consistent with the inner diameter of a conduit to be scribed, the conduit weighing rings are sleeved at two ends of the pull rod, and the conduit to be scribed is sleeved on the pull rod and covers the whole pull rod and the conduit weighing rings.

The scribing method using the scribing device comprises the following steps:

1, firstly sleeving a conduit balance ring on a pull rod, sleeving a conduit to be scribed on the pull rod, and then installing the whole conduit between two brackets.

2, adjusting the size of the connecting plate of the left end face of the marking ruler and the marking tool bit to the distance from the guide pipe to be marked.

And 3, tightly attaching the end surface of the left side of the scribing ruler to the binding surface of the bracket and the guide pipe, rotating the guide pipe, and finishing scribing by the scribing cutter head on the guide pipe.

The invention has the beneficial effects that:

1) the device is flexible to use, can accurately measure and rapidly demarcate the size of the allowance of the conduit to be removed, and can be adjusted in real time according to the specific condition of the part;

2) the device can perform scribing and allowance removing processing on most of guide pipe parts in a mode of replacing a weighing ring;

3) the device has expansibility, can be transformed aiming at guide pipe parts with different sizes and types, and realizes accurate marking;

4) the device is convenient to maintain, the processing of the marking plate which is frequently worn is simple, the device can be continuously used after being replaced, and all components of the whole device can be quickly replaced.
