Problems solved by technology

If the "horseshoe" of the rocket guide is not precisely processed, there will be installation stress on the rocket guide when it is installed on the rocket, and the stress will easily aggravate and cause the rocket guide to break, bringing a potential fatal risk to the rocket (see "Missile and Space Launch Technology / Missiles and Space Vehicles, "Stress Corrosion of Rocket Piping and Its Preventive Measures" in Issue 01, 2005)
[0006] With the development of my country's aerospace industry, in recent years, some end-cutting and flat-mouth processing equipment have been adopted successively. These equipment will reliably clamp the conduit during processing, and then use cutting saw blades to cut the conduit, which can neatly cut off the redundant parts at both ends of the conduit. , after cutting, the end face of the tube is processed by a flat end tool, but the whole process is still mainly controlled manually, mainly relying on human experience. There is a phenomenon of repairing due to the deviation of the installation end face, which affects the rocket manufacturing progress and product quality
Moreover, in the prior art, the device for clamping the conduit is usually fixed by screws, and it takes a lot of time to replace the clamping device each time, which directly affects the mass production of the rocket.

Abstract

The invention discloses a pipe fitting cutting device and a horseshoe cutting method thereof. The pipe fitting cutting device includes a fuselage on which a cutting device and a conduit clamping device are installed, and the conduit clamping device includes a first clamping seat , the second clamping seat and the clamping device base, the first clamping seat and the second clamping seat are arranged on the clamping device base opposite to each other front and back, and the two cooperate with the clamping conduit front and back, and the first clamping seat is fixed on On the base of the clamping device, the second clamping seat is driven by the clamping motor or the third clamping cylinder to slide back and forth on the base of the clamping device. The base of the clamping device is installed on the body through a rotating shaft and can be driven by rotation The device is driven to rotate, and the cutting device feeds forward and backward. The axis of the rotating shaft is located on the cutting surface of the cutting device. The axes of the shafts intersect. This scheme can quickly and accurately cut and form the horseshoe mouth.

Description

technical field [0001] The invention relates to the technical field of aerospace and pipe fittings processing, in particular to a pipe fitting cutting device and a horseshoe cutting method thereof. Background technique [0002] There are tens of thousands of accessories on aerospace vehicles such as airplanes and rockets, and many accessories are connected by metal conduits. For example, there are many metal conduits on the rocket body and engine, which are used to transmit various fluids and support the rocket. It is an extremely important part of the rocket for various tasks of flight. "Rocket Propulsion / Journal of Rocket Propulsion" 2018 Issue 03 "Liquid Rocket Engine Piping Fracture Failure Analysis and Power Optimization" explains that: the safety and reliability of the liquid rocket engine piping system has become the key to whether the engine can work safely key. [0003] Due to the complex shape of the aerospace catheter, it is necessary to use CNC pipe bending equ...
