Description

Technical Field

[0001] This invention relates to a method for manufacturing aircraft stop washers and a special tool for automated manufacturing, belonging to the field of aircraft assembly technology. Background Technology

[0002] Bolt anti-loosening is an indispensable and crucial part of aircraft assembly. Effective anti-loosening measures enhance the stability and reliability of aircraft assembly. Especially during high-speed flight, aerodynamic forces, elastic forces, and inertial forces generate self-excited vibrations. Under these conditions, all threaded connections are susceptible to loosening, necessitating the selection of appropriate anti-loosening measures. In the assembly and manufacturing of aerospace products, a large number of individual bolt connections with specific functions are unavoidable. Suitable anti-loosening methods must be selected for these connections. Typically, to prevent the failure of individual bolt connections, in addition to tightening to the specified torque, aerospace-grade locking washers are used to achieve an anti-loosening effect, thereby enhancing the reliability of aircraft connections and extending the aircraft's service life.

[0003] Aviation-grade locking washers are primarily used to prevent loosening of single bolt connections with specific functions. They are mainly used in products such as tie rods, conduit clamps, and grounding wire installations. Since bolts have specific functions, good anti-loosening performance can prevent accidents caused by connection failure. Locking washers are one of the most effective methods for preventing bolt loosening. Quality requirements include: the locating claw should fit tightly against the part, protruding ≥2mm from the part; the fixing claw should protrude >2mm from the nut; and the installation of the washer on the flange and the bending of the locating claw, or their limiting movement at the convex end, should prevent the washer from rotating towards the loosened side. Uneven force applied by the operator often leads to a lack of tight fit between the locating claw and the part, causing rotation and connection failure. Currently, locking washers are mainly made manually, using pliers to tap the locating claw downwards for positioning, and then simultaneously clamping the fixing claw and nut for fixation. This method is simple to operate and easy to learn. However, it is not allowed to repeat the operation after the first unsatisfactory process. Adjustment is prone to quality problems such as shearing or material movement, cracks and breakage in the bending parts. Therefore, manual casting is inefficient and has poor quality control. In addition, manual casting can easily damage the stop washer and nut. Improper operation during casting can also injure the operator and cause serious safety accidents. Summary of the Invention

[0004] The present invention provides on-site operators with a method for manufacturing aircraft locking washers to prevent loosening and a special tool for automated manufacturing, in order to solve the problems mentioned in the above-mentioned technical background.

[0005] The beneficial effects of this invention are:

[0006] An automated tool for manufacturing aircraft stop washers includes a data acquisition section, a mechanical structure section, and a digital control section. The data acquisition section mainly collects the rotation speed of the servo motor and feeds the data back to the digital control section to complete the control function. The mechanical structure section is the structural part of the invention, which supports the entire special device and completes the manufacturing of the stop washers. The digital control section is mainly used to realize the automatic manufacturing function of the stop washers.

[0007] like Figure 1 As shown, the mechanical structure consists of a main support body, bearings, a lead screw, a connecting block, a lead screw sleeve, a support shaft, symmetrical working blocks, a secondary support body, a telescopic motor, a rotary servo motor, a double-ended stud, and a lower working block. The main support body, bearings, lead screw, connecting block, lead screw sleeve, support shaft, and symmetrical working blocks complete the fabrication of the retaining washer fixing claw. The main support body is the primary support structure of this invention; the data acquisition section, mechanical structure section, and digital control section are all attached to the main support body. The outer ring of the bearing is interference-fitted with the main support body, and the inner ring of the bearing is interference-fitted with the lead screw, mainly ensuring smooth rotation of the lead screw within the hole on the main support body. The lead screw is the primary transmission structure of this invention; it is helically connected to the lead screw sleeve, which can drive the rotary servo motor... The rotation is transmitted to the lead screw sleeve: the rotation servo motor is the power part for the fixing claw of the stop washer in this invention. The screw output is transmitted through the lead screw, which is equipped with a rotation sensor to collect the output rotation of the rotation servo motor and feed it back to the microcontroller for processing; the lead screw sleeve is the receiving component of the screw drive in this invention. It is interference-fitted with the connecting block and can convert the rotation of the lead screw into the forward and backward movement of the connecting block, realizing the transmission from rotation to movement; the connecting block is the connecting component of this invention. It is interference-fitted with the support shaft and can convert the helical motion into linear motion; the support shaft connects the connecting block and the symmetrical working block to ensure that the symmetrical working block and the connecting block move synchronously; the symmetrical working block is the execution component of this invention, which is used to complete the fixing claw of the stop washer. The auxiliary support body, telescopic motor, double-ended stud, and lower working block complete the fabrication of the stop washer positioning claw. The auxiliary support body is the main support component for fabricating the stop washer positioning claw of this invention, used to support the mechanical structure and digital control parts. It is bolted to the main support body, fixing the auxiliary support body to the main support body. The telescopic motor is the power component for fabricating the stop washer positioning claw of this invention, using its telescopic movement to transmit linear output power. It has a threaded hole at its bottom for connection. The double-ended stud is the connecting component for fabricating the stop washer positioning claw, connecting the telescopic motor and the lower working block, and transmitting the linear power of the telescopic motor to the lower working block. The working block is the actuating component for fabricating the stop washer positioning claw of this invention, used to complete the fabrication of the stop washer positioning claw.

[0008] The digital control section consists of components such as a vertical cover plate, base, screws, extension button, retraction button, switch button, forward button, back button, reset button, microcontroller, power module, charging module, and controller. The vertical cover plate, base, and screws form the mechanical support structure for the digital control section, supporting the extension button, retraction button, switch button, forward button, back button, reset button, microcontroller, power module, charging module, and controller. Screws connect the vertical cover plate and base to prevent misalignment. The switch button and reset button enable and disable the stop washer setting device. The switch button controls the setting of the stop washer. The power supply is controlled to enable and disable the entire system. The reset button is used when the stop washer is completed or when a quality problem occurs during the process requiring temporary retraction. It can also be used for the initial power-on reset self-test of the stop washer making device. The extend and retract buttons are the control buttons for making the stop washer positioning claw. The extend button starts the making process, driving the telescopic motor to extend the operating rod, which in turn moves the double-ended stud and the lower working block to complete the making of the stop washer positioning claw. The retract button controls the retraction of the telescopic motor rod after the stop washer positioning claw making is completed, returning the telescopic motor rod to its original position. (The text also mentions forward and retract buttons, but these are not directly related to the main function.) The buttons are control buttons for the pressing of the stop washer fixing claw. The forward button controls the rotation servo motor to rotate clockwise, which drives the lead screw to rotate. The lead screw and lead screw sleeve generate relative motion, which in turn drives the support shaft and symmetrical working blocks to move forward, completing the pressing of the stop washer fixing claw. The retract button is used to control the rotation servo motor to rotate counterclockwise after the stop washer fixing claw is pressed, which in turn drives the symmetrical working blocks to move backward. The power module and charging module are the main electrical components of this invention. The power module is the power supply module of this device, which can store electrical energy and provide the required electrical energy for the entire system, supplying electrical energy to the telescopic motor, rotation servo motor, speed sensor, and single... The microcontroller and controller are the main control components of this invention. The charging module is used to complete the charging function of this invention and realize the charging of the power module. The microcontroller and controller are the main control components of this invention. They are used to realize the information processing and instruction transmission of this device. The microcontroller is the core processing component of this invention. It is used to receive and process the data collected by the rotation sensor, generate control instructions, and transmit the instructions to the controller. The controller is the control component of this invention. It is used to coordinate the release of signals from the microcontroller. When the rotation data of the rotation sensor reaches the maximum rotation number set by the microcontroller, the rotation servo motor stops rotating. At this time, the telescopic motor starts to operate and can automatically complete the molding of the stop washer positioning claw and the fixing claw.

[0009] The data acquisition section mainly collects the signals required for control. It consists of a rotation sensor and a microcontroller. The rotation sensor collects the rotation number of the servo motor and transmits the rotation number to the microcontroller via signal transmission. The microcontroller analyzes and processes the collected information and issues the required instructions.

[0010] A method for manufacturing aircraft locking washers, comprising the following steps:

[0011] Step 1: Take out the stop washer making device, check whether the device label is complete, whether the calibration date is within the validity period, and whether the appearance is intact;

[0012] Step 2: Press the switch button, and the power module will supply power to the entire stop washer making device to start the stop washer making device. Press the reset button to make the stop washer complete the self-test after the first power-on.

[0013] Step 3: Press the forward button. The microcontroller transmits the signal to the controller. The controller issues an instruction to drive the servo motor to rotate clockwise. This, in turn, drives the symmetrical working block to move forward through the lead screw, connecting block, lead screw sleeve, and support shaft. When the rotation sensor reaches the set number of rotations, it sends a signal back to the microcontroller. The microcontroller then transmits the signal to the controller. The controller issues an instruction to stop the servo motor, thus achieving the pressing of the retaining washer fixing claw.

[0014] Step 4: After completing Step 3, press the extend button. The microcontroller transmits a signal to the controller, which then sends an instruction to drive the telescopic motor to extend the working rod, causing the double-headed stud and the lower working block to move downwards, thereby striking the positioning claw of the stop washer.

[0015] Step 5: After completing Step 4, press the retraction button. The microcontroller will transmit a signal to the controller, which will then issue a command to drive the telescopic motor to retract the working rod, causing the double-headed stud and the lower working block to move upwards and return them to their original positions.

[0016] Step Six: After completing Step Five, press the rewind button. The microcontroller transmits a signal to the controller, which then sends a command to drive the servo motor to rotate counterclockwise. This, in turn, drives the symmetrical working block to rewind via the lead screw, connecting block, lead screw sleeve, and support shaft. When the rotation sensor reaches the set number of rotations, it sends a signal back to the microcontroller, which then transmits the signal to the controller. The controller then sends a command to stop the servo motor.

[0017] Step 7: After completing Step 6, press the reset button to ensure that the symmetrical working block and the lower working block are restored to their initial positions;

[0018] Step 8: After completing Step 7, return the stop washer making device to its original position for the next measurement.

[0019] The beneficial effects of this invention are:

[0020] Analysis of existing methods for manufacturing stop washers reveals that traditional manual manufacturing methods are prone to damaging the bolt surface, and manual operation is extremely prone to manufacturing deviations, causing the lugs of the stop washer to bend repeatedly. This results in stop washers that do not meet aviation standards, where the lugs can only be bent once. Furthermore, human factors have a significant impact on the manufacturing quality of stop washers. These problems seriously affect the manufacturing quality of stop washers and the work efficiency of operators.

[0021] To address and avoid the aforementioned problems, the present invention provides an automated manufacturing device for aircraft stop washers. This device automates the manufacturing of stop washers, reducing the impact of human intervention on the quality of the manufacturing process. Furthermore, the use of a rotation sensor and microcontroller control ensures that the manufacturing meets the requirements in a single pass, eliminating the need for repeated bending of the stop washer lugs and avoiding violations of process regulations.

[0022] This automated stop washer making device has a simple structure, small size, and is easy to carry. It can be operated by a single person. The making process is achieved by using a rotary servo motor and a telescopic motor, which can reduce the operator's labor intensity, enhance the reliability and safety of bolt connections, and improve customer satisfaction.
