Description

Technical Field

[0001] This invention relates to the technical field of welding aircraft flap rail structural components, and in particular to a welding device for aircraft flap rail structural components. Background Technology

[0002] The flap rail structure is the core load-bearing rail component of the trailing edge Fuller flap sliding lift enhancement mechanism. It is fixed to the lower surface of the wing and provides an arc-shaped motion trajectory for flap retraction and extension. At the same time, it bears all the aerodynamic loads and inertial loads of the flap. It is a first-level key load-bearing structural component of the aircraft. Welding equipment is used when welding the rail structure.

[0003] The prior art patent number CN104999208A discloses a welding fixture for vacuum electron beam welding of aircraft flap slide rail structural components. Before welding, the slide rail body is fixed to one side surface of the fixture body with fasteners and clamping parts through positioning holes and positioning blocks, so that the cavity of the slide rail body corresponds to the window hole of the fixture body; the corresponding web plates are welded to one side surface of the slide rail body cavity by vacuum electron beam welding in the order of adjacent intervals.

[0004] However, before actual welding, multiple sets of fasteners and clamping parts need to be fixed to the slide rail body on the fixture body, which makes the operation more laborious. After welding, the welded structural parts need to be removed before the remaining structural parts can be fixed and the welding work can continue.

[0049] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0050] This invention discloses a welding device for aircraft flap rail structural components. (Refer to...) Figures 1-7 A welding device for aircraft flap slide rail structural components includes: a welding device body 1, with feed grooves 22 provided at the middle of both the left and right sides of the welding device body 1; a fixed frame 2 connected to the feed grooves 22 on both sides of the welding device body 1; two clamp bodies 3 respectively disposed in the two fixed frames 2; a moving switching structure disposed on the fixed frames 2, which alternately moves and switches the two clamp bodies 3 into the welding device body 1 to perform welding work on the slide rail structural components; a clamping structure disposed on the clamp bodies 3 to clamp the slide rail structural components; a driving structure disposed on the fixed frames 2, which drives the clamping structure to automatically clamp the slide rail structural components while the clamp bodies 3 are moving and switching; a cleaning structure disposed inside the welding device body 1 to clean the inner surface of the welding device body 1; a collecting structure disposed inside the welding device body 1 to collect impurities generated during welding and cleaning; and a heat dissipation structure disposed in the collecting structure to dissipate heat and collect impurities.

[0051] See Figures 1-7 The clamping structure includes: a clamping plate 5 on one side of the clamp body 3, and a clamping plate 6 on the other side of the clamp body 3. The clamping plates 5 and 6 are arranged close to each other to adapt to the shape of the slide rail structure. Multiple windows 4 are opened in the middle of the clamp body 3 for inserting the cavity of the slide rail body. Several protrusions 8 are provided on the close sides of the clamping plates 5 and 6. The moving switching structure includes: guide grooves 11 on the inner walls of the front and rear sides of the fixed frame 2. A moving plate 9 is slidably arranged in each group of two guide grooves 11. A U-shaped frame 10 is connected to each moving plate 9. The clamp body 3 is fixedly installed on the U-shaped frame 10. The two U-shaped frames 10 are fixedly connected by a connecting frame 21. The right side of the fixed frame 2. A motor 12 is installed on the right side. One end of the output shaft of the motor 12 is connected to a screw 13, and the other end of the screw 13 is rotatably connected to the main body 1 of the welding device. A moving block 14 is connected in the middle below the moving plate 9 on the right side. The moving block 14 has a threaded groove for the screw 13 to pass through. The driving structure includes: two sliding grooves 15 opened below the fixture body 3. A sliding plate 17 is slidably arranged in each sliding groove 15. A connecting rod 16 is connected to the sliding plate 17. One end of the two connecting rods 16 is connected to clamping plate 5 and clamping plate 6 respectively. Two fixing plates 18 are connected between the two fixing frames 2. Each fixing plate 18 has a driving groove 19. A driving rod 20 is connected below each sliding plate 17. The driving rod 20 moves through the driving groove 19.

[0052] Before welding, the cavity of the slide rail body is aligned with the window hole 4 on one of the clamp bodies 3. The motor 12 is started to drive the screw 13 to rotate. One of the moving plates 9 drives the clamp body 3 and the slide rail body on the corresponding U-shaped frame 10 to move into the welding device body 1. During the movement, the moving plate 9 drives one end of the driving rod 20 to slide in the driving groove 19 of the fixed plate 18. Under the guidance of the driving groove 19, the driving rod 20 drives the slide plate 17 to slide in the sliding groove 15, thereby driving the clamping plate 5 and clamping plate 6 to move on the clamp body 3. Since the clamping plate 5 and clamping plate 6 are close to each other and their sides are adapted to the shape of the slide rail body, and the clamping plates are used to move the slide rail body, the slide rail body is moved into the welding device body 1. The protruding strips 8 on clamping plates 5 and 6 allow them to move towards each other, directly clamping and fixing the slide rail bodies inside each window hole 4 on the clamping body 3. This makes the operation more labor-saving and convenient. After clamping, the moving plate 9 moves the clamped slide rail bodies into the welding device body 1 for welding. At the same time, another clamping body 3 moves out of the welding device body 1. Thus, while disassembling the welded slide rail bodies on the other clamping body 3 and replacing the slide rail bodies to be welded, welding continues inside the welding device body 1, making full use of the working time and improving welding efficiency.

[0053] See Figures 5-7 The collection structure includes: a slot 23 located in the middle of the main body 1 of the welding device, into which a collection frame 24 is movably inserted, and a handle 26 is installed on the front of the collection frame 24; a material discharge groove 25 is provided on the upper wall of the slot 23, and the material discharge groove 25 is connected to the welding space inside the main body 1 of the welding device; the cleaning structure includes: electric push rods 29 installed on the left and right sides of the main body 1 of the welding device; a lifting block 31 is provided at the bottom of the output shaft of the electric push rod 29, a lifting frame 30 is installed on the lifting block 31, and bristles 32 that are close to the inner wall of the main body 1 of the welding device are provided on the side of the lifting frame 30; the heat dissipation structure includes: a filter plate 27 installed in the collection frame 24; multiple heat dissipation grooves 28 are provided on the front of the collection frame 24, and an exhaust fan is installed at the bottom inside the collection frame 24;

[0054] During welding, the exhaust fan inside the collection frame 24 is activated to dissipate the heat generated during welding in the main body 1 of the welding device through the heat dissipation tank 28. At the same time, when the electric push rod 29 is activated to move the lifting frame 30 up and down, the brush 32 on the lifting frame 30 is used to clean the impurities and dust adhering to the inner side wall of the main body 1 of the welding device. Simultaneously, the airflow generated by the exhaust fan is used to absorb the dust generated during the cleaning process into the collection frame 24 for collection, which facilitates centralized treatment and avoids the problem of dust generated during the cleaning process being directly discharged from the main body 1 of the welding device, thus reducing the quality of the working environment.

[0055] The implementation principle of the welding device for aircraft flap rail structure components according to an embodiment of the present invention is as follows: First, before welding, the cavity of the rail body is aligned with the window hole 4 on one of the clamp bodies 3. The motor 12 is started to drive the screw 13 to rotate. A moving plate 9 drives the clamp body 3 and the rail body on the corresponding U-shaped frame 10 to move as a whole into the welding device body 1. During the movement, the moving plate 9 drives one end of the driving rod 20 to slide in the driving groove 19 of the fixed plate 18. Under the action of the lever 20, the slide plate 17 slides in the slide groove 15, thereby causing the clamping plates 5 and 6 to move as a whole on the clamping body 3. Since the clamping plates 5 and 6 are close to each other and their sides are adapted to the shape of the slide rail body, and with the use of the protrusions 8 on the clamping plates 5 and 6, when the clamping plates 5 and 6 move towards each other, the protrusions 8 directly clamp and fix the slide rail body in each window hole 4 on the clamping body 3. The operation is more labor-saving and convenient. Afterwards, the moving plate 9 moves the clamped slide rail body into the welding device body 1 for welding. At the same time, another clamp body 3 moves out of the welding device body 1. Thus, while the welded slide rail body is being disassembled on the other clamp body 3 and the slide rail body to be welded is being replaced, welding continues inside the welding device body 1, making full use of the working time and improving welding efficiency. During welding, the exhaust fan in the collection frame 24 is activated to exhaust the heat generated during welding inside the welding device body 1 from the heat dissipation tank 28 for heat dissipation. At the same time, when the electric push rod 29 is activated to move the lifting frame 30 up and down, the brush 32 on the lifting frame 30 is used to clean the impurities and dust adhering to the inner wall of the welding device body 1. Simultaneously, the airflow generated by the exhaust fan absorbs the dust generated during the cleaning process into the collection frame 24 for collection, which is convenient for centralized treatment and avoids the problem of dust generated during the cleaning process being directly discharged from the welding device body 1, thus reducing the quality of the working environment.

[0056] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
