Description

Technical Field

[0001] The invention relates to a method for making a stop washer for an aircraft and a special tool for automatic making the same, belonging to the technical field of aircraft assembly. Background Art

[0002] Bolt connection anti-loosening is an important part of the aircraft assembly process. A good anti-loosening method is conducive to increasing the stability and reliability of aircraft assembly, especially when the aircraft is flying at high speed. Due to the effects of aerodynamic force, elastic force and inertial force, a self-excited vibration of the aircraft will be generated. When working under such vibration conditions, all threaded connections may loosen, so it is necessary to select good anti-loosening measures as needed. In the assembly and manufacturing process of aviation products, it is inevitable that there are a large number of single bolt connections with specific functions. It is necessary to select a suitable anti-loosening method for anti-loosening treatment. Usually, in order to prevent the failure of a single bolt connection, in addition to tightening the torque as required, it is also required to use aviation lock washers to achieve anti-loosening effect, so as to enhance the reliability of aircraft connections and extend the service life of aircraft.

[0003] The aviation stop washer is mainly used to prevent the loosening of a single bolt connection with a specific function. It is mainly used in products such as tie rods, conduit clamps, and ground wire installations. Bolts are used for specific functions. Good anti-loosening effects can avoid accidents caused by connection failure. Stop washers are a better anti-loosening method for bolts. The quality requirements are that the positioning claws should fit tightly with the parts, protruding from the parts ≥2mm, and the protrusion of the fixing claws on the nut >2mm. The installation of the washers on the flange and the bending of the washer positioning claws or their limiting at the ends of the convex edges should avoid the possibility of the washers rotating toward the loosening side. The operator often applies uneven force, resulting in the positioning claws not fitting tightly with the parts and causing the possibility of rotation, which may cause the connection to fail. At present, the production of stop washers is mainly pure manual production, that is, using a vise to knock the positioning claws down for positioning, and then clamping the fixing claws and nuts at the same time for fixing. This method is simple to operate and easy to use. However, repeated operation is not allowed if the hammering fails once. Adjustment is prone to quality problems such as shearing or material movement, cracks and breakage at the bending parts. Therefore, manual hammering is inefficient and has low quality control. In addition, manual hammering can easily damage the stop washers and nuts. Improper operation during the hammering process may also injure the operator and cause serious safety accidents. Summary of the invention

[0004] The present invention aims to provide a method for preventing aircraft stop washers from loosening and a special automatic manufacturing tool for on-site operators, so as to solve the problems in the above technical background.

The controller (24) is a control component of the present invention, and is used to coordinate and release signals from the single chip microcomputer (21). When the rotation data of the rotation sensor (17) reaches the maximum number of rotations set by the single chip microcomputer (21), the rotation servo motor (16) stops rotating, and the telescopic motor (15) starts to operate at this time, and the positioning claw and the fixing claw of the stop washer can be automatically completed.

9. A method for making a special tool for automatic making of aircraft lock washers according to any one of claims 1 to 8, characterized in that: Here are the steps: Step 1: Take out the stop washer making device and check whether the device labels are complete, whether the verification date is within the validity period, and whether the appearance is intact; Step 2: Press the switch button (13), the power module (22) will supply power to the entire stop washer making device, start the stop washer making device, press the reset button (20), and make the stop washer complete the self-check after the first startup; Step 3: Press the forward button (18), the single chip microcomputer (21) transmits a signal to the controller (24), the controller (24) issues a command to drive the rotating servo motor (16) to rotate clockwise, and then drives the symmetrical working block (7) to move forward through the screw (3), the connecting block (4), the screw sleeve (5) and the support shaft (6). When the speed sensor (17) reaches the set speed, the signal is fed back to the single chip microcomputer (21), and then the single chip microcomputer (21) transmits a signal to the controller (24), and the controller (24) issues a command to stop the rotating servo motor (16), thereby realizing the forging of the stop washer fixing claw; Step 4: After step 3 is completed, the extension button (11) is pressed, and the single chip microcomputer (21) transmits a signal to the controller (24). The controller (24) issues a command to drive the telescopic motor (15) to extend the working rod, driving the stud (25) and the lower working block (26) to move downward, thereby achieving the forging of the stop washer positioning claw; Step 5: After step 4 is completed, the retraction button (12) is pressed, and the single chip microcomputer (21) transmits a signal to the controller (24). The controller (24) issues a command to drive the telescopic motor (15) to retract the working rod, drive the stud bolt (25) and the lower working block (26) to move upward, and restore the stud bolt (25) and the lower working block (26) to their original positions; Step 6: After step 5 is completed, the retract button (19) is pressed, and the single chip microcomputer (21) transmits a signal to the controller (24), and the controller (24) issues a command to drive the rotating servo motor (16) to rotate counterclockwise, and then drives the symmetrical working block (7) to retract through the screw (3), the connecting block (4), the screw sleeve (5) and the support shaft (6).
