Description

Technical Field

[0001] The utility model relates to the technical field of aviation equipment maintenance, in particular to a screw-in type elbow nozzle angle measuring tool. Background Art

[0002] Various types of actuators on aircraft are equipped with screw-in elbow pipe nozzles, which are connected to the conduits on the aircraft. Since there are a large number of conduits on the aircraft and their directions are complex, the angles of the screw-in elbow pipe nozzles installed on the actuators on the aircraft are different. The angles of the screw-in elbow pipe nozzles need to be fixed and measured according to the drawings. The angles of the screw-in elbow pipe nozzles are spatial dimensions. Existing angle gauges are only suitable for plane angle measurement and cannot complete the spatial angle measurement of the screw-in elbow pipe nozzles on the actuators. Therefore, in order to ensure the reliability of the connection between the elbow pipe nozzle of the actuator and the conduit on the aircraft, and to ensure the stress-free state of the connecting conduit, it is necessary to design a tooling that can meet the angle measurement needs of the screw-in elbow pipe nozzles on the aircraft actuators, and at the same time meet the requirements of simple structure, convenient maintenance and high measurement efficiency.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0024] like Figures 1 to 10 As shown, a screw-in bent pipe nozzle angle measuring tool includes a horizontal mounting seat 3 fixed on the lower support plate of the vise for mounting an actuator 9, and also includes two guide rods 2 respectively tightened on the screw-in bent pipe nozzle 10, a measuring plate of a multifunctional angle ruler 1 aligned with the guide rods 2, and a rotating clamping rod 7 horizontally fixed to another measuring plate of the multifunctional angle ruler 1.

[0025] The horizontal mounting seat 3 is provided with a through hole of Φ6.5 mm. The measuring tool is a small rectangular, three-dimensional tool with a moderate size, a small footprint, convenient maintenance and high filling efficiency.

[0026] The actuator 9 is passed through the through hole by a hexagonal bolt 5 and tightened with a hexagonal nut 6. During measurement, the lower support plate of the horizontal mounting seat 3 is fixed on the vise, and the actuator 9 is fixed on the horizontal mounting seat 3. The two guide rods 2 are respectively tightened on the screw-in bent pipe nozzle, and one of the measuring plates of the multifunctional angle ruler 1 is fixed horizontally with a rotating clamping rod. The other measuring plate of the multifunctional angle ruler 1 is aligned with the guide rod 2. At this time, the angle displayed by the multifunctional angle ruler 1 is the angle of the screw-in bent pipe nozzle, and the entire measurement process does not require a motor power source.

[0027] The utility model effectively solves the problems of difficult spatial angle measurement, low measurement accuracy and low measurement efficiency of the screw-in bent pipe nozzle of the actuator on the aircraft; through long-term practical use, the screw-in bent pipe nozzle angle measurement tool is very suitable for the problems of many types of screw-in bent pipe nozzles, small batches and different angles during aircraft repair, and plays an obvious role in improving the repair and maintenance efficiency of the actuator on the aircraft.

[0028] The angle displayed by the multifunctional angle ruler 1 is the angle of the screw-in elbow nozzle 10 .

[0029] The multifunctional angle ruler 1 is clamped in the middle of the rotating clamping rod 7, and the guide rod 2 is cleverly used to extend and mark the axis of the nozzle. At the same time, the clamping rod 7 is rotated to fix one of the measuring plates of the multifunctional angle ruler horizontally, and the other measuring plate is aligned with the guide rod. At this time, the value displayed on the angle ruler is the measured value, that is, the angle measurement is realized.

[0030] The horizontal mounting seat 3 is fixed with a small bracket 4 by a hexagonal bolt 8. Four groups of small brackets 4 are provided. The small bracket 4 is fixed by a hexagonal bolt 8. A rotating clamping rod 7 is installed on the small bracket 4. The multifunctional angle ruler 1 can be fixed by rotating the rotating clamping rod 7. Four Φ6.5mm through holes are provided on the horizontal mounting seat 3. The actuator 9 is fixed by a hexagonal bolt 5 and a hexagonal nut 6. The guide rod 2 is tightened on the screw-in elbow nozzle 10.

[0031] Fix the lower support plate of the horizontal mounting seat 3 on the vise, fix the actuator 9 on the horizontal mounting seat 3, tighten it with the hexagonal head bolt 5 and the hexagonal nut 6, tighten the two guide rods 2 on the screw-in bent pipe nozzle 10 respectively, fix one of the measuring plates of the multifunctional angle ruler 1 horizontally with the rotating clamping rod 7, align the other measuring plate of the multifunctional angle ruler 1 with the guide rod 2, and the angle displayed by the multifunctional angle ruler 1 is the angle of the screw-in bent pipe nozzle 10. When measuring the angle of another screw-in bent pipe nozzle 10, it is only necessary to rotate the multifunctional angle ruler 1 180 degrees and fix it horizontally with the rotating clamping rod 7. The whole measuring process is simple to operate and efficient.
