Description

Technical Field

[0001] The utility model relates to the technical field of engine parts processing, in particular to a guiding and positioning tool for engine parts processing. Background Art

[0002] There are three liquid rocket engines with liquid hydrogen and liquid oxygen as propellants at the tail of the space shuttle, which are called main engines. The structures of the three main engines are exactly the same. The engine has two pre-combustion chambers. Most of the fuel output by the turbopump and a small part of the oxidizer are burned in the pre-combustion chamber with rich fuel (oxygen: hydrogen is about 0.8). The gas temperature is about 600-700℃, which is used to drive the turbine, and then discharged into the main combustion chamber for supplementary combustion with the remaining oxidizer, forming high-temperature and high-pressure gas discharged from the combustion chamber nozzle. The three main engines together can provide more than 60 tons of thrust. When processing aerospace engine parts, they need to be positioned and clamped.

[0003] The Chinese authorized announcement number CN218488176U is a clamping tool for processing engine parts. By evenly arranging a number of positioning columns in a rectangular array on the bottom plate, the positions of two pairs of positioning sleeves can be appropriately adjusted according to the specifications of the parts. The positioning components set between the positioning sleeves and the positioning columns can facilitate the rapid disassembly and assembly of the two. The cooperation between the studs and the adjusting cylinders can adjust the heights of each clamping component separately, thereby adapting to the clamping of non-standard parts, improving the versatility of the device, and bringing convenience to people's use.

[0004] There are still certain shortcomings in use. When clamping parts, they are fixed by bolts. After long-term use, the bolts will slip, which will reduce the clamping quality of the parts. At the same time, only fixing with bolts will also reduce the fixing effect and quality of the parts, reduce the processing quality of the parts, and limit the practicality of the clamping tooling.
