Description

Technical Field

[0001] This utility model belongs to the field of UAV control surface manufacturing, maintenance, storage and transportation, and specifically relates to a six-station control surface continuous patching storage and transportation integrated operation frame. Background Technology

[0002] In the field of composite material manufacturing for UAVs, reinforcing the control surface seams with fabric is a key process to ensure the structural strength of the aircraft. Currently, the industry commonly employs a two-person manual operation mode: one person holds the control surface (800-1500mm in length, ≤1000g) by hand or using a simple clamp, while the other person manually applies epoxy resin and applies fiberglass cloth. This mode is sustainable for small-batch production, but when faced with the demand for batches of over a thousand units per year, the following systemic defects are exposed:

[0003] 1. Prominent efficiency bottlenecks

[0004] Serialized single-piece operation: Only one control surface is processed at a time, clamping and disassembly account for more than 40% of the operation time, and the time for a single piece is ≥30 minutes;

[0005] Curing interruption on the production line: After the fabric is applied, it needs to be left to cure before it can be transferred, which causes the production line to be congested and the maximum output per person per day is only 7 pieces.

[0006] Redundancy in auxiliary time: Repeatedly changing gloves and preparing adhesive materials reduces the effective working time to less than 60%, with glove changing alone taking 5 minutes per glove.

[0007] 2. Loss of control over quality consistency

[0008]

[0009] 3. Secondary damage during storage and transportation

[0010] Pre-curing displacement: Manual handling and collision before the epoxy resin has cured resulted in 15% displacement of the adhesive layer;

[0011] Scratches after curing: The lack of dedicated storage racks and stacking resulted in an average of 1.5 scratches per item.

[0012] Annual scrap cost ≥ 200,000 yuan (calculated based on 1,600 pieces × 10% scrap rate × cost per piece of 1,200 yuan).

[0013] 4. Poor adaptability to mass production

[0014] Insufficient length compatibility: Handheld operation cannot stably support rudder surfaces in the 800-1500mm range, making mixed-line production difficult;

[0015] Ergonomics flaw: After 4 hours of continuous operation, operator arm fatigue caused a 20% decrease in the pass rate;

[0016] Excessive process fluctuations: relying entirely on worker experience, with a quality standard deviation >20% (requirement ≤5%).

[0017] In summary, existing technologies cannot simultaneously achieve efficient continuous operation, millimeter-level application accuracy, zero-damage storage and transportation, and adaptability to mixed-line production, severely hindering the mass production process of UAV control surfaces. Currently, there is an urgent need for a dedicated device that supports rapid clamping, continuous operation, and integrated storage and transportation to fundamentally solve the above problems. Therefore, this utility model proposes a six-station integrated operation frame for continuous application and storage of control surfaces. Summary of the Invention

[0026] A further technical solution of this utility model is: the end of the indexing drive shaft 10 is provided with an indexing plate, and the indexing plate is connected to the hexagonal rotating bracket 6 by the indexing quick-release positioning pin 11.

[0029] A further technical solution of this utility model is: the H-type pulley rail 4 is made of 40Cr steel quenched and hardened, and the double-layer guide rail is equipped with a nylon slider.

[0031] A further technical solution of this utility model is: the central disk of the hexagonal rotating bracket 6 has a threaded hole along the radial direction, which is connected to the central hole of the mounting indexing drive shaft. The rocker-type locking screw (2) is installed in the threaded hole, and the radial force is applied to the indexing drive shaft by screwing to realize the positioning of the hexagonal rotating bracket 6.

[0053] Existing technologies cannot simultaneously achieve efficient continuous operation, millimeter-level application accuracy, zero-damage storage and transportation, and adaptability to mixed-line production, severely hindering the mass production process of UAV control surfaces. This utility model proposes a six-station integrated operation frame for continuous application and storage of control surfaces, comprising:

[0054] The hexagonal rotating bracket 6 and two sets of hexagonal rotating brackets are coaxially connected through the centrally located indexing drive shaft 10 to form a hexagonal prism frame structure with adjustable wheelbase.

[0055] H-type pulley rail 4, two sets of H-type pulley rail 4 are symmetrically installed below two hexagonal rotating brackets 6 through triangular vertical brackets 5, as wheelbase adjustment components, and anti-collision blocks are provided at the ends;

[0057] The six clamping points of the hexagonal rotating bracket 6 are all equipped with rudder surface quick-release positioning pins 8, and continuous operation is achieved through a 60° indexing and indexing mechanism.

[0058] Specifically, the 60° indexing mechanism includes a hexagonal indexing rocker wheel 1 and an indexing drive shaft 10 connected coaxially. The indexing drive shaft is connected to a hexagonal rotating bracket 6, and the hexagonal indexing rocker wheel 1 serves as the driving component of the hexagonal rotating bracket 6.

[0059] Specifically, the indexing drive shaft 10 is provided with an indexing plate at its end, and the indexing plate is connected to the hexagonal rotating bracket 6 by the indexing quick-release positioning pin 11.

[0065] Specifically, the top vertex of the triangular vertical bracket 5 is fixed to the hexagonal rotating bracket 6, and a pair of H-shaped pulleys are installed on the bottom two vertices respectively, forming a set of H-shaped pulley rails.

[0066] The above technical solution will be further explained below with reference to the accompanying drawings and examples:

[0067] In one embodiment, refer to Figure 1 As shown, the materials and mechanical structure of each component of the integrated storage and transportation operation frame with continuous fabric application on the six-station control surface in this embodiment are broken down as follows:

[0068] Hexagonal rotating bracket 6: 6061-T6 aviation aluminum alloy, hexagonal frame, central indexing drive shaft φ50mm, anodized.

[0069] The quick-release positioning pin 8 for the rudder surface is made of TC4 titanium alloy with a stepped structure (φ8) and a telescopic spring. The pin is precision machined. After 10,000 insertion and removal tests, the wear of the pin body is less than 0.03, which still meets the tolerance requirements.

[0070] H-type pulley rail 4: 40Cr steel + nylon slider, double-layer guide rail, stepless adjustment of stroke from 800 to 1500 mm, hardened by quenching (HRC45).

[0071] Pressure roller: Silicone roller surface, 50mm wide, anti-static.

[0072] Anti-collision corner protectors: polyurethane rubber, corner protector thickness ≥15mm, Shore hardness 55A±5, L-shaped edging, corner radius R10mm.

[0073] The indexing drive shaft is made of 10:45# steel, heat-treated and sandblasted.

[0074] The key parameters of the components in this embodiment are shown in the table below:

[0075]

[0076] In one embodiment, refer to Figure 2 As shown, the mating relationship between the quick-release locating pin and the rudder mounting hole is as follows:

[0077] The cone of the quick-release locating pin on the rudder surface: φ8mm at the large end, cone angle 5.7°;

[0078] Control surface mounting hole: φ8H9 (+0.03 / 0mm)

[0079] Self-alignment principle: Tapered guidance + 0.05mm gap compensation for installation deviation.

[0080] In one embodiment, refer to Figure 5 As shown, the slide rail-bracket adjustment system consists of an H-type pulley slide rail 4 and a slide rail bracket 5. The H-type pulley slide rail 4 has a stepless adjustable stroke of 800-1500mm, which is compatible with the length of the control surface. By adjusting its position, it can be adapted to different models of control surfaces.

[0081] In one embodiment, refer to Figure 3 As shown, the coordination relationship of the 60° indexing mechanism is as follows: indexing wheel → indexing drive shaft (indexing plate divided into 60° equal parts) → hexagonal rotating bracket rotates 60° → quick-release positioning pin fixes. Operation flow: rocking the indexing wheel --> indexing drive shaft (indexing plate divided into 60° equal parts) → hexagonal rotating bracket rotates 60°, spring pin automatically locks → rudder surface indexing.

[0082] Operating procedures:

[0083] 1. Synchronous clamping:

[0084] Adjust the H-type pulley rail 4 to the position that matches the length of the rudder surface, and at the same time lock the indexing drive shaft 10 by the rocker-type locking screw (2);

[0085] Insert the 6 control surfaces into the locating pins in sequence (pressure value approximately <5N), taking ≤3 minutes.

[0086] 2. Dual-station operation:

[0087] Workstation A: Operator 1 applies epoxy resin (E-51 type) to the seam with a brush and applies 40mm wide glass cloth;

[0088] Station B: Operator 2 uses a pressure roller to assist in pressing (0-15N adjustable) to eliminate air bubbles, achieving a smooth, flat, and tight finish.

[0089] Shifting: After completing the current two control surfaces, rock the shifting wheel to switch to a new control surface and continue working (without interrupting the operation, waiting for materials, glue, or control surfaces, and without changing gloves).

[0090] 3. Solidification and storage:

[0091] The entire operating frame is pushed into an 80℃ heating chamber for curing for 2 hours;

[0092] Unlock the universal wheel brakes and transfer it to the warehouse (the bracket frame corner protectors prevent collisions).

[0093] Integrated protection against damage through fabric patching, storage, transportation, and maintenance.

[0094] In one embodiment, an example of the application effect of this control frame to a certain type of UAV rudder (with closed control surfaces, 1020mm in length, and 850g in weight) is shown below:

[0095] Application scenario: Reinforcing the seam of the rudder of a certain type of UAV with fabric (epoxy resin + fiberglass cloth) rudder surface:

[0096] Process requirements: The seam should be covered with 3 layers of glass cloth (40mm wide), free of bubbles, and smooth and flat.

[0097] Operator feedback:

[0098] Clamping process: It only takes 3 minutes to fix the 6 rudder surface pins;

[0099] Fabric application process: Fabric application at station A → Compacting and flattening at station B → Rotation, a smooth cycle with no waiting required;

[0100] Curing and transport: When pushed into the 80℃ heating chamber, the silicone tires did not soften, and the corner guards and anti-collision strips prevented accidental impact;

[0101] Efficiency Comparison Test

[0102]

[0103] Key efficiency gains:

[0104] The rotation time is ≤3 seconds (1.25 rotations of the crank wheel), allowing the operator to work continuously throughout the entire process;

[0105] It saves time from repeatedly preparing adhesive and cleaning the countertop.

[0106] Based on practical examples, this utility model has the following outstanding advantages:

[0107] 1. Synchronous clamping of six control surfaces + continuous operation in two stations → Eliminates the pain points of repeated clamping and adhesive contamination;

[0108] 2. Stepless adjustment of sliding rails + integrated storage and transportation → covering 800~1500mm rudder surfaces;

[0109] 3. Completes 6 control surfaces in a single operation, → efficiency increased by 200%;

[0110] 4. Zero bumps and knocks during transport (traditional manual handling has a 5% damage rate), → product quality improved by 75%.

[0111] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
