Abstract

The invention provides a high lock nut discontinuity inspection sample preparation device, including a cutting device, a base, a servo motor fixed on the base, a positioning plate coaxially fixed with the main shaft of the servo motor, Four zeroing electrodes on the two corners, a plurality of through holes evenly opened along the length direction of the positioning plate, and positioning nails and controllers threaded through the through holes and high lock nuts. The high-lock nut discontinuity inspection sample preparation device of the present invention improves the positioning accuracy of the closing point, increases the amount of clamping at one time, reduces the rework rate of sample preparation, and avoids the impact of external forces on sensitive positions of nuts such as twisting grooves. influences.

Description

technical field [0001] The invention belongs to the field of detection tooling, in particular to a high lock nut discontinuity inspection sample preparation device. Background technique [0002] High-lock nuts are widely used as aircraft body fasteners because of their excellent pre-tightening force control and anti-loosening functions, as well as their light weight and quick installation on one side. The consumption of a single aircraft can reach more than 10,000 pieces, and its product performance directly affects the operation status of the aircraft and the personal safety of the passengers. [0003] like figure 1 and figure 2 As shown, the high lock nut consists of three parts: [0004] 1) The wrench structure is in the shape of a hexagon. Use a ratchet wrench or a special wind trigger to wrench it to apply the installation torque; [0005] 2) The broken neck groove structure is mainly used to control the installation torque, and the twisting torque directly affects...
