Description

Technical Field

[0001] This invention belongs to the field of anti-loosening technology for aircraft actuator bolts, specifically relating to an automatic rotary cutting and grinding device for anti-loosening of stainless steel wires. Background Technology

[0002] Aircraft actuators are among the core systems affecting aircraft safety, function, and performance. Actuator assembly, as a crucial link in the entire actuator manufacturing process, directly impacts the actuator's operational stability, safety, and related performance parameters. Fastener anti-loosening is a core assembly process for aircraft actuators. The auxiliary material for fastener anti-loosening typically uses stainless steel wire of varying diameters to prevent loosening of bolts, pipe fittings, electrical boxes, and other fasteners. The general fastener anti-loosening process mainly involves threading, braiding, and finishing. Before use, the stainless steel wire often needs to be cut to a certain length using needle-nose pliers. The cut stainless steel wire has sharp edges of approximately 20-50° at both ends, and these edges contain burrs. When anti-loosening the actuator's fasteners, the stainless steel wire can easily scratch the valve body as it passes through the fuse hole, causing product appearance quality problems. This leads to significant customer complaints, repeated requests for resolution, and returns after delivery due to appearance issues, severely impacting normal production and field quality. Meanwhile, stainless steel wire cutting is currently done manually using needle-nose pliers and shearing pliers, which is a non-value-adding process, affecting normal production rhythm and easily generating excess material. To solve the problems of sharp edges, burrs, and non-value-adding processes caused by manual cutting of stainless steel wire, an automatic rotary cutting and grinding device and method for preventing loosening of fasteners in aerospace actuators was designed.

[0084] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0085] The following difficulties exist in manually cutting stainless steel wire:

[0086] 1) Stainless steel wire used for fastening aircraft actuators is traditionally cut to the required length using tools such as pliers or needle-nose pliers. After cutting, the stainless steel wire forms sharp edges of approximately 20-50° at both ends, and these edges contain burrs. When fastening actuators, the stainless steel wire can easily scratch the valve body as it passes through the fuse hole, causing product appearance defects. Furthermore, the sharp edges of the stainless steel wire can unintentionally injure the operator.

[0087] 2) Hydraulic products have a large delivery volume, with each product requiring 20-100 stainless steel wires. Manual cutting is inefficient and is a non-value-adding process, resulting in a discontinuous production process.

[0088] 3) Excess material is easily generated during the cutting of stainless steel wire, which can easily contaminate high-precision aerospace actuator hydraulic products. Therefore, the equipment needs to cut the wire in batches before production preparation and then deliver it on site.

[0089] 4) Hydraulic products have different structures and different anti-loosening parts for bolts. The stainless steel wire used is of different specifications and lengths. The lengths are inconsistent due to manual cutting, and the stainless steel wire is repeatedly replaced during use, resulting in low production efficiency.

[0090] 5) During the stainless steel wire processing, automatic feeding is required, and the material tray mechanism needs to be designed to adapt to different stainless steel wire cores.

[0091] 6) The stainless steel wire used for fastening aircraft actuators is relatively soft. The finished stainless steel wire is delivered in a spool, and the stainless steel wire is deformed. Therefore, it is necessary to consider straightening the stainless steel wire before cutting it.

[0092] 7) Stainless steel wire used for fastening aircraft actuators is generally available in sizes such as φ0.3, φ0.5, and φ0.8. Since the diameter of the stainless steel wire is relatively small, it is necessary to solve the problem of how to make the sharp edge after being cut by pliers smooth and burr-free through equipment.

[0093] Based on the above difficulties and problems, the present invention provides an automatic stainless steel wire rotary cutting and grinding device and method for preventing loosening of fasteners in aircraft actuators, comprising: a stainless steel wire tray mechanism, a fuse rotary cutting and grinding box, a first stainless steel wire straightener 13, a second stainless steel wire straightener 14, a first traction device 15, a second traction device 16, a first traction tube 17, a stainless steel wire rotary cutting mechanism 18, a grinding mechanism 19, a second traction device 20, a second traction tube 21, a horizontal fixing plate 22, and a stainless steel wire 23.

[0094] A horizontal fixing plate 22 is used to fix and install the first stainless steel wire straightener 13, the second stainless steel wire straightener 14, the first traction device 15, the second traction device 16, the first traction tube 17, the stainless steel wire rotary cutting mechanism 18, the grinding mechanism 19, the second traction tube 21, and the second traction device 20.

[0095] The stainless steel wire feeder mechanism is located on the left side of the fuse rotary cutting and grinding box and is used for automatic feeding of stainless steel wire.

[0096] This invention relates to an automatic rotary cutting and polishing device for stainless steel wire used to prevent loosening of fasteners in aircraft actuators. It can realize the functions of automatic feeding of stainless steel wire from the material tray mechanism, fixed length cutting, batch processing, rotary cutting, flexible polishing, and automatic storage.

[0097] The stainless steel wire rotary cutting mechanism of this invention is one of the core components of the automatic rotary cutting and grinding device for preventing loosening of fasteners in aerospace actuators. The stainless steel wire rotary cutting mechanism is equipped with a motor that can achieve constant speed 360° rotation. The stainless steel wire rotary cutting mechanism can achieve forward and reverse rotation, and the forward and reverse rotation times can be flexibly adjusted according to the specifications of the stainless steel wire.

[0098] Based on the selected stainless steel wire diameter, this invention allows for the setting of both forward and reverse rotation times of the stainless steel wire slicing mechanism to 0 for stainless steel wires with smaller diameters, thus enabling the slicing of stainless steel wires.

[0099] The stainless steel wire rotary cutting mechanism of this invention uses a custom-made special steel double blade to cut the stainless steel wire. The blade tip is V-shaped to ensure a uniform cut after cutting.

[0100] The stainless steel wire rotary cutting mechanism of this invention uses a shaping cutter. Through high-speed rotation, the two V-shaped cutter heads gradually close together, eventually squeezing out the fuse, and the fracture surface presents a hemispherical shape.

[0101] To prevent fine burrs on the shaped surface and at the final central fracture, this invention optionally includes a polishing mechanism. A flexible polishing belt is used to polish the ends; custom-made ring-shaped flexible sandpaper is used for flexible polishing of the stainless steel wire. The polishing mechanism of the automatic rotary cutting and polishing device for preventing loosening of stainless steel wire fasteners in aerospace actuators can perform forward and reverse polishing of the stainless steel wire, with adjustable polishing time. It can simultaneously polish both ends of the stainless steel wire, resulting in high efficiency and excellent polishing effect.

[0102] The automatic rotary cutting and grinding device for preventing loosening of stainless steel wire fasteners in this invention uses a compressed air pneumatic device for the cutting mechanism, while the grinding mechanism and guiding mechanism are electrically driven. It has a simple structure, is lightweight, easy to install and maintain, safe to use, low cost, fast action, quick response, low delay, high reliability, long service life, and can be standardized, serialized and universalized.

[0103] The automatic rotary cutting and grinding device for anti-loosening stainless steel wire fasteners of the present invention has parameter design for each mechanism, and each mechanism can be controlled individually. The device also has functions such as automatic return to mechanical zero position and automatic traction. All parameters can be customized for users to use in secondary development.

[0104] The present invention relates to a rotary cutting mechanism in an automatic rotary cutting and grinding device for preventing loosening of stainless steel wire fasteners in aircraft actuators. After rotary cutting and grinding, the stainless steel wire has no sharp edges at both ends, and the surface is smooth and burr-free. During the fastening and loosening of the actuator, the scratches on the stainless steel wire as it passes through the fuse hole are reduced by 100%.

[0105] The present invention provides an automatic rotary cutting and grinding device for anti-loosening of stainless steel wire fasteners for aircraft actuators. It can achieve automatic feeding, and the stainless steel wire tray mechanism can be adaptively designed according to different stainless steel wire tray cores, and can adapt to different specifications of tray cores on the market.

It can perform rotary cutting and grinding on stainless steel wire, metal materials, steel wire rope and other materials of different specifications on the market. It has a wide range of applications and strong adaptability.

[0107] The present invention relates to an automatic rotary cutting and grinding device for preventing loosening of stainless steel wire fasteners in aircraft actuators. It is designed with horizontal and vertical stainless steel wire straighteners to straighten the finished product feeding fuses that are coiled or bent. The horizontal and vertical straighteners are both double-sided.

[0108] The present invention provides a stainless steel wire straightener for both horizontal and vertical directions, which can adjust the tension of stainless steel wires of different diameters.

[0109] Core Innovation Point 14: The automatic rotary cutting and grinding device for anti-loosening of stainless steel wire fasteners of aircraft actuators is designed with a traction device and a guide tube, which can realize the automatic guidance of stainless steel wire and pull the stainless steel wire to the stainless steel wire rotary cutting mechanism.

[0110] The automatic rotary cutting and grinding device for preventing loosening of stainless steel wire fasteners in aircraft actuators of the present invention is designed with a first traction device 15, a second traction device 16, and a first traction tube 17 after the straightener to realize the automatic traction of stainless steel wire from the material tray mechanism and the straightener to the inlet of the rotary cutting mechanism; after exiting the stainless steel wire rotary cutting mechanism 18 and the grinding mechanism 19, a second traction tube 21 and a second traction device 20 are designed to realize the traction of the rotary-cut and ground stainless steel wire to the storage bin.

[0113] The automatic rotary cutting and grinding device for preventing loosening of stainless steel wire fasteners in aircraft actuators has a wire breakage detector installed between the straightener and the traction device to detect the remaining amount of stainless steel wire. When the stainless steel wire in the wire spool is used up, the safety mechanism is finally triggered by the wire breakage detector, and the equipment stops operating.

[0114] For example, the wire breakage detector is located between the straightener 14 and the traction wheel 15. The wire breakage detector mainly consists of a thin aluminum sheet and an infrared detection device. The thin aluminum sheet is placed on the fuse. When the last fuse passes through the traction wheel and there are no more fuses, the thin aluminum sheet will automatically retract because there are no fuses. When the infrared device detects the aluminum sheet passing through, it automatically cuts off the equipment.

[0207] In other embodiments of this application, the automatic rotary cutting and grinding device for anti-loosening of stainless steel wire fasteners of aircraft actuators can perform rotary cutting and grinding on stainless steel wire, metal materials, steel wire rope and other materials of different specifications on the market. It has a wide range of applications and strong adaptability.

[0208] In other embodiments of this application, a method for automatically rotary cutting and grinding stainless steel wire to prevent loosening of specific aircraft actuator fasteners is disclosed:

[0209] Step 1: Open the roller locking device of the stainless steel wire tray mechanism, move the stainless steel wire tray mechanism and place it on the left side of the fuse rotary cutting and grinding box, close to the stainless steel wire straightening mechanism.

[0210] Step 2: Pass the stainless steel wire coil to be processed through the material tray rack and place it on the stainless steel wire tray mechanism. Install the limiter to fix the stainless steel wire coil and prevent the wire tray from moving horizontally during the feeding process.

[0211] Step 3: Pass the stainless steel wire end through the second, third, and first stainless steel wire traction wheels respectively. When the stainless steel wire passes through the second and third stainless steel wire traction wheels, the stainless steel wire forms a "figure-eight" shape. After exiting from the third stainless steel wire traction wheel, it passes through the first stainless steel wire traction wheel.

[0212] Step 4: After the stainless steel wire passes through the first stainless steel wire traction wheel, it enters the first stainless steel wire straightener through the small hole in front of the first stainless steel wire straightener. Open the horizontal locking wrench and the vertical locking wrench, and after passing the stainless steel wire through the vertical straightening wheel and the horizontal straightening wheel, close the horizontal locking wrench and the vertical locking wrench. At the same time, adjust the adjustment button installed on the straightening wheel to adjust the straightening force and ensure that the straightening force in the vertical and horizontal directions is uniform.

[0213] Step 5: Connect the stainless steel wire automatic rotary cutting and grinding device with compressed air to the aircraft actuator fastener anti-loosening device to provide pneumatic performance for the equipment;

[0214] Step 6: Use the dedicated software for the automatic rotary cutting and grinding device for anti-loosening of stainless steel wire fasteners of aircraft actuators. Enter the manual page, set the manual speed of traction T1 axis and traction T2 axis, place the stainless steel wire head between the first traction wheel and the fourth traction wheel, and click "pull forward" in the program. At this time, the stainless steel wire moves, passes through the first traction device and the second traction device, and then passes out from the second traction device.

[0215] Step 7: Continue to click "Forward Pull" in the program to pass the stainless steel wire end through the first pulling tube. The first pulling tube hole is designed with a 45° bevel to ensure that the stainless steel wire can be freely passed into the first pulling tube. The stainless steel wire passes through the first pulling tube, passes through the guide shaft of the stainless steel wire rotary cutting mechanism, and exits from the stainless steel wire rotary cutting mechanism. At this time, the pre-feeding step of the stainless steel wire is completed.

[0216] Step 8: If any abnormality occurs in the stainless steel wire during the manual traction process described above, click "Pull Backward" to retract the stainless steel wire.

[0217] Step 9: Open the dedicated software for the automatic rotary cutting and grinding device for stainless steel wire with anti-loosening fasteners of aircraft actuators, and enter the "Parameter Settings" page. Adjust the traction parameters and set the feeding length, feeding compensation, rapid advance length, and feed length of the stainless steel wire according to the specifications of the stainless steel wire used.

[0218] Step 10: Enter the "Parameter Settings" page, set the forward and reverse rotation time of the stainless steel wire veneer cutting mechanism, set the forward and reverse grinding time of the grinding mechanism, and set the grinding belt speed.

[0219] Step 11: After setting the above parameters, return to the main page of the dedicated software for the automatic rotary cutting and grinding device for stainless steel wire with anti-loosening of aircraft actuator fasteners. Reset the production count and belt wear to zero, and set the rotary cutting and grinding quantity. Click "Reset the whole machine" to restore all mechanisms of the device to the zero position; click "Reset" to clear all information on the software interface.

[0220] Step 12: After clicking "Start", the automatic rotary cutting and grinding device for anti-loosening stainless steel wires of aircraft actuator fasteners will start running. It will perform rotary cutting and grinding according to the set number of stainless steel wires until the production count is consistent with the number of rotary cutting and grinding, at which point the device will stop running.

[0221] Step 13: After clicking "Start", the stainless steel wire in the stainless steel wire tray passes through the second stainless steel wire traction wheel 88, the third stainless steel wire traction wheel 89 and the first stainless steel wire traction wheel 86 in sequence. Then the stainless steel wire passes through the first stainless steel wire straightener 13 for vertical straightening. After straightening is successful, it passes through the second stainless steel wire straightener 14 for horizontal straightening. During this process, the first traction device 15 and the second traction device 16 are also running.

[0222] Step 14: With the traction force set by the first traction wheel 34 and the fourth traction wheel 37, the second traction wheel 35 and the third traction wheel 36, the stainless steel wire passes through the first traction tube in sequence. According to the set forward and reverse rotary cutting time, the rotary cutting lower blade 52 and the rotary cutting upper blade 53 are driven by the motor to perform 360° rotary cutting on the stainless steel wire.

[0223] Step 15: The lower rotary cutting blade 52 and the upper rotary cutting blade 53 are connected by a certain elastic spring under pneumatic drive, and are used for the cutting motion of the lower rotary cutting blade 52 and the upper rotary cutting blade 53, at which time the stainless steel wire is cut.

[0224] Step 16: After the stainless steel wire is cut, under the control of the motor, the rotary cutting and grinding mechanism moves to both ends of the stainless steel wire, and the customized ring sandpaper on the rotary cutting and grinding mechanism performs soft grinding on both ends of the stainless steel wire.

[0225] Step 17: After the stainless steel wire is rotary cut and polished, the rotary cutting and polishing mechanism returns to the zero position under the control of the motor. At this time, the second traction tube 21 is started, guiding the stainless steel wire to the second traction device 20. The stainless steel wire is placed into the automatic receiving bin 5 through the second traction device 20.

[0226] Extensive experiments have demonstrated that this invention, through its designed stainless steel wire tray mechanism, stainless steel wire straightener, stainless steel wire guide and guide tube, stainless steel wire rotary cutting mechanism, grinding mechanism, and automatic storage bin, achieves the automatic feeding, guiding, rotary cutting, and grinding of stainless steel wire for preventing loosening of aircraft actuator fasteners. It solves the problems of sharp edges, burrs, and non-value-adding processes caused by manual cutting of stainless steel wire in existing systems. The invention features automatic batch processing of stainless steel wire to a fixed length, rotary cutting, flexible polishing, and automatic storage, with an efficiency of 120-180 pieces / hour. It also produces aesthetically pleasing, dustproof products, reducing scratches and dents during product assembly and adjustment, significantly mitigating the limitations of traditional manual cutting, avoiding non-value-adding processes, and effectively improving the appearance quality of aircraft actuator products.
