Problems solved by technology

In the process of aircraft production, it is necessary to make round holes larger than φ40mm on thin-walled parts such as aircraft siding, skin, and flat glass. Based on the large area of ​​the round hole, the general method is to clamp the front end of the air drill or electric drill. Holding a cylindrical thin-walled hole saw, the end face of the cylindrical thin-walled hole saw is toothed or inlaid with emery, and further, the operator holds an air drill or an electric drill to open the part. This operation has the following defects: using the air drill Or the electric drill cooperates with the hole saw to open the hole. When the cutting operation is performed, the cutting part of the end face of the hole saw cuts into the part as a whole. The cutting force is large and it is easy to move in the radial direction. The device is easy to slide, causing damage to the surface of the parts, and there are certain safety hazards

Abstract

The invention relates to the technical field of aircraft component assembly and hole making, in particular to an anti-vibration stabilizer for a cylindrical thin-wall hole opener, which includes a ring body base and a pressure bearing assembly; the ring body base is provided with more than three The linear guide groove of the pressure-applying bearing assembly, and the pressure-applying adjustment plate used to control the pressure-applying bearing assembly to move back and forth radially along the ring body base; multiple pressure-applying bearing assemblies cooperate with each other to limit the opening at the center of the ring body base Hole moves. This technical scheme adopts the ring body base as support, and multiple pressure bearing components cooperate to support and position the hole saw. It can effectively protect the surface of parts, improve the quality of opening holes, and provide safety guarantee for operators.

Description

technical field [0001] The invention relates to the technical field of aircraft component assembly and hole making, in particular to an anti-vibration stabilizer for a cylindrical thin-wall hole saw. Background technique [0002] With the continuous development of aerospace technology, the production and assembly technology of various parts more and more meet the high-performance requirements of the aircraft, but the performance of the aircraft has not yet reached the best expectations of human beings, and the aircraft manufacturing technology needs to be continuously improved. In the process of aircraft production, it is necessary to make round holes larger than φ40mm on thin-walled parts such as aircraft siding, skin, and flat glass. Based on the large area of ​​the round hole, the general method is to clamp the front end of the air drill or electric drill. Holding a cylindrical thin-walled hole saw, the end face of the cylindrical thin-walled hole saw is toothed or inlaid...
