Problems solved by technology

At this time, the distance between the rotary center and the tool is relatively close. If the program is wrong or human operation is wrong, it is very easy to cause a direct collision between the tool and the steel rotary center.
The sparks generated by the collision between the tool and the rotating center can cause the solid propellant powder to burn and cause serious fire accidents
At the same time, the vertebral body of the rotary top head is in a state of high-speed rotation, and the propellant powder produced during the turning process is easy to enter the rotation gap of the rotary top, which becomes a risk of combustion or explosion.

Embodiment Construction

[0015] The present invention will be further explained below through specific embodiments and accompanying drawings.

[0016] Such as figure 1 , in the rotary top safety isolation device for solid propellant charge turning, the guide cone 1 is made of beryllium bronze with high strength and good wear resistance, and the tolerance zone of the cylindrical hole on the inner surface is designed to be H7, which ensures that The rotating head is closely matched, and has the functions of installation, fixing and guiding. The tapered hole on the inner surface is designed to have a busbar angle of 60°. The inner surface of the guide cone 1 is polished to a roughness of 1.6-3.2 to ensure close connection with the conical rotary head of the rotary top and to realize the positioning of the tapered hole. A small hole Φ5.0mm is processed at the right end of the tapered hole to avoid interference between the rotary head and the tapered hole. The left end of the outer surface of the guide ...

Abstract

The invention discloses a live center safety isolation device for turning machining of solid propellant loading. The live center safety isolation device for turning machining of solid propellant loading comprises a guiding cone, an isolating body and a protective coating, wherein the guiding cone is made of beryllium bronze and is bonded with the isolating body through epoxy resin; the isolating body is made of a high-silica laminated cloth rod, the protective coating is made of epoxy resin and the outer surface of the isolating body is coated with the protective coating in a spraying mode. The live center safety isolation device solves the safety problems that during turning machining of solid propellant loading, a steel turning tool and a steel live center mistakenly collide and fires are caused, and is suitable for turning machining of solid propellant loading.

Description

technical field [0001] The invention relates to a turning processing device for solid propellant charge, which is mainly suitable for solid propellant charge processing. [0002] technical background [0003] Solid propellant charge is the core of rocket motor and the key technology for the development of solid propulsion technology. After more than 50 years of development, my country's solid propellants have developed various types and uses of propellants such as double-base, modified double-base, composite, and NEPE. According to the filling method, propellant charges are generally divided into shell-bonded type and free-loading type. The free-filling solid propellant charge is currently the engine charging method with the largest number of equipment in China. Depending on the mission of the engine, solid propellant charges need to be prepared in different structural shapes. Among the many processing methods, the turning of rotary bodies using machine tools is the most co...
