Grinding tool and grinding method for guide pipe orifice angle

Abstract

Provided are a grinding tool and a grinding method for a guide pipe orifice angle. The grinding tool comprises a grinding head, a guide rod, a compaction spring and a thread guide sleeve. The grindinghead is located at the front end of the guide rod, the grinding head is of a rigid structure with a tapered grinding surface, the angle of the tapered grinding surface is matched with the angle surface of an orifice of a guide pipe, the thread guide sleeve is a revolution body, a guide hole is formed in the center of the thread guide sleeve, a bearing is inlaid in the center of the thread guide sleeve, external threads are arranged on the outer side of the thread guide sleeve, the guide rod is inserted into the guide hole, and the compaction spring is located among the grinding head, the guide rod and the bearing. The thread guide sleeve of the grinding tool is connected with a cap nut of the orifice of a guide pipe part, the grinding head is pressed in the orifice of the guide pipe underthe action of the compaction spring, the grinding head is rotated through a handle at the tail of the guide rod to realize the purpose of rough grinding of the angle of the orifice of the grinded guide pipe.

Description

Technical field: [0001] The invention relates to the production and manufacturing technology of aircraft conduits, in particular to the processing and manufacturing of the nozzle angle of the conduit, especially the grinding of the nozzle angle which requires airtightness and high surface roughness when the nozzle is installed. Background technique [0002] There are thousands of conduits in aircraft parts, such as air pipes, oil pipes, etc., all over the aircraft. At present, angles are commonly used in the assembly of aircraft pipelines at home and abroad, such as 74°, 45°, etc. The advantages of this process are that the process of processing and installation is simple, and the cost is relatively low. The disadvantage is that the installation stress of the conduit Larger, prone to leakage. When assembling on the aircraft, the angle open end of the pipe is matched with the standard part joint, and the two ends of the standard part joint are opposite angles with the same a...
