[0016] Example

[0017] An aircraft seat parachute shooting mechanism locking machine assembly turning angle measuring tool, the measuring tool includes a handle 1, a worm 3, a worm gear 4, a pinion 6, a large gear 7, a pointer 9, a turntable 10, a positioning pin, and a dial 12 And working board 13; the peripheral device is the parachute locking machine;

[0018] The worm 3 is a single-head worm 3, the modulus of the worm 3 and the worm wheel 4 are both 0.5, the number of teeth of the worm wheel 4 is 120 teeth, the transmission ratio of the worm 3 to the worm wheel 4 is 120:1; the large gear 7 and the small gear 6 The modulus of is 1, the number of teeth of the large gear is 120 teeth, the number of teeth of the small gear is 40 teeth, and the transmission ratio of the large gear 7 and the small gear 6 is 3:1;

[0019] The inner diameter of the dial 12 is greater than the outer diameter of the large gear 7; the reading of the dial 12 is 0°-60°;

[0020] The overall connection relati...

Abstract

The invention discloses an aircraft seat parachute-shooting mechanism assembling rotation angle measuring tool for a bomb locking machine, which belongs to the technical field of aviation equipment. The measuring tool includes a handle, a worm, a worm wheel, a pinion, a large gear, a pointer, a turntable, a positioning pin, a dial and a working plate; one end of the worm is fixed on the worm supporting seat of the working plate, and the other end is fixedly connected with the handle; The pinion and the worm gear are installed coaxially on the transmission sleeve I on both sides of the working plate, wherein the worm gear meshes with the worm; the large gear is coaxially installed on the transmission sleeve II on the working plate, and the small gear and the large gear Mesh and be on the same plane; the pointer, positioning pin and turntable are all fixedly connected with the big gear; the dial is fixedly connected with the working plate, and the dial is coaxial with the big gear; the tested part is connected with the big gear through the turntable. When the handle shakes 1 circle, the rotation angle of the rocker arm is 1°; since there is a sound when the tested part is excited, it can be judged whether the tested part is qualified or not by reading the rotation angle of the large gear.

Description

technical field [0001] The invention relates to an aircraft seat parachute-shooting mechanism assembling rotation angle measuring tool for a bomb-locking machine, which belongs to the technical field of aviation equipment. Background technique [0002] The repair quality of the aircraft seat directly affects the quality of the aircraft. The aircraft seat parachute-shooting mechanism is equipped with a locking machine to check the angle of rotation of the rear rocker arm when it is activated. . If the swing angle of the rocker arm of the seat parachute mechanism is less than 22° when it is activated, it will be activated in advance, causing the seat headrest (survival parachute) to separate in advance. If the pilot is not ready, it is easy to cause personal injury to the pilot; When it exceeds 32°, it will not activate, causing the seat headrest (survival parachute) to not separate from the seat, and the parachute will not work, resulting in ejection failure and directly aff...
