AI Technical Summary
In the existing technology, during the bonding process of aircraft windshields, the lack of limiting of the bonding pressure plate causes the clamping to move easily, making it difficult to guarantee the bonding quality. This is especially true for large curved glass parts, where the bonding stability and bonding strength are insufficient.
An aircraft windshield bonding device was designed, including an arc-shaped clamp, a bracket, a frame, and wheels. The bonding area is limited and fixed by multiple components of the arc-shaped clamp, the bracket which simulates the shape of the windshield to ensure the stability of the glass placement, and the bonding area is limited in multiple directions by a force bar and a top block. The device is combined with a V-shaped clamp for pressure curing.
It achieves all-round positioning and fixation of aircraft windshields, improves bonding quality, prevents delamination caused by clamp displacement, and ensures the stability and strength of the bond.

Abstract
Description
Technical Field
[0001] This application relates to an aircraft windshield bonding device, which is used to limit the bonding area and ensure bonding quality when bonding polyester tape around the windshield of a certain type of fighter jet. Background Technology
[0002] The aircraft windshield is a critical component of the life-saving system and serves as the pilot's window to the outside world. During flight, it bears not only aerodynamic loads but also the pressurized loads within the cockpit. For a certain type of aircraft, the windshield glass uses J-189 polyurethane adhesive to bond polyester ribbon, which is then connected and fixed to the windshield frame. Therefore, the bonding strength is crucial, and the process is controlled as a key characteristic during repair. Besides ensuring the bonding position and dimensions, a certain amount of pressure must be applied to the bonding area. See the diagram for a schematic of the windshield bonding process. Figure 1 .like Figure 1 This model's windshield features a notched design, requiring polyester tape to be bonded along both the horizontal and vertical edges of the notch. The windshield bonding process uses a bonding plate and V-clamps to directly apply pressure to the bonding area. However, this method has two drawbacks: first, the bonding plate lacks a limiting position, making it prone to shifting during clamping and causing delamination; second, because the windshield is a large curved glass component, placing it open during bonding makes it difficult to ensure stability, affecting the bonding quality. Summary of the Invention
[0003] According to one aspect of this application, an aircraft windshield bonding device is provided, comprising an arc-shaped clamp 1, a bracket 2, a frame 3, and wheels 4;
[0004] The bow-shaped clamp 1 is a clamping fixture of the device, which is bow-shaped, with three on the rear arc, four on the left side, three on the right side, one on the front arc, one on the horizontal side of the notch, and one on the vertical side of the notch, for a total of 13.
[0005] The bracket 2 is a combination of horizontal and vertical plates, which are screwed together by corner pieces. It supports the windshield and the internal groove arc shape is consistent with the outer surface of the windshield.
[0006] The frame 3 is the rigid structure of the device, mainly connected and fixed to the bracket 2 by the crossbeam, and connected and fixed to the wheel 4 at the bottom.
[0007] The four wheels 4 are installed at the bottom of the bracket and are used for transporting the device. The wheels are equipped with positioning devices. When the device is transported to the designated position, the positioning devices are stepped on to fix the device in place.
[0008] The bow-shaped clamp 1 consists of a force-applying rod a, a lead screw b, a large top block c, a support arm d, a small top block e, an indexing pin f, a screw g, a baffle h, and a screw sleeve i.
[0009] The force-adding rod a is installed in the screw hole at the top of the lead screw b with clearance fit, and can slide in the screw hole. The two ends of the force-adding rod a are made of abutment to prevent it from falling off.
[0010] The lead screw b has a thread in the middle and is screwed to the support arm d. The movement of the lead screw b within the support arm d is achieved by rotating the force rod a, ensuring that the size of the lead screw b is adjustable. The lead screw b is screwed to and fixed to the large top block c and the small top block e.
[0011] The large top block c is screwed to the lead screw b and is cylindrical. It moves with the lead screw b during use and serves as the upper and lower limit of the pressure plate.
[0012] The support arm d is screwed to the lead screw b. The bottom of the support arm d has two mounting holes, one large and one small. The large hole is fitted with the baffle h through the screw g and the screw sleeve i. The support arm d can rotate around the screw g and the screw sleeve i. The small hole is connected and fixed with the indexing pin f, which is convenient for disassembly.
[0013] The small top block e is screwed to the lead screw b and is cylindrical. It moves with the lead screw b during use and serves to limit the left and right positions of the pressure plate.
[0014] The indexing pin f connects the support arm d and the baffle h together, and directly transitions with the support arm d and the baffle h, serving as a positioning pin.
[0015] The screw g is screwed into the screw sleeve i, connecting the support arm d and the baffle h together for easy disassembly. There is a smooth rod on the screw g, which is clearance-fitted with both the support arm d and the baffle h, ensuring that the support arm d can rotate around the smooth rod part of the screw g.
[0016] The baffle h is L-shaped, with its bottom screwed to the bracket 2, and its vertical part connected to the baffle h via an indexing pin f, a screw g, and a threaded sleeve i.
[0017] Instructions for use (in) Figure 1 (as shown in the state)
[0018] 1. Remove the indexing pins f from all the devices, and rotate the bow-shaped clamp 1 around the screw g to open it.
[0019] 2. Place the windshield to be glued on bracket 2.
[0020] 3. Use the inner and outer adhesive plates to close the adhesive joint, rotate the bow-shaped clamp 1 around the screw g to close it, and insert the indexing pin f to fix the bow-shaped clamp 1.
[0021] 4. Rotate the top force bar a to make the large top block c stick to the inner and outer adhesive pressure plates, thereby limiting the upper position of the adhesive pressure plates.
[0022] 5. Rotate the two force-applying rods a on both sides so that the two small top blocks e press against the two sides of the adhesive plate to achieve lateral positioning.
[0023] 6. After the limiting work is completed, V-clamps are used to load the inner and outer adhesive plates to achieve the pressure curing function.
[0024] 7. After the adhesive has cured, disassemble the device in the reverse order described above to complete the work.
[0025] The advantages of this application are:
[0026] This application provides an aircraft windshield bonding device that can fix and limit all bonding areas to ensure bonding quality. This device uses a specially designed bracket that mimics the shape of the windshield to ensure the stability of the glass placement. Specialized bow-shaped clamps are used around the device to limit the shape and size of the upper and sides of the bonding area, preventing delamination caused by clamp displacement.
