Welding workbench for aerospace empennage sheet machining

Abstract

The utility model relates to the technical field of aerospace empennage piece machining, in particular to a welding workbench for aerospace empennage piece machining, which comprises a workbench body, a movable table is arranged at the top of the workbench body, and a hydraulic oil cylinder is fixedly connected to the inner surface of the movable table; the welding workbench has the beneficial effects that according to the welding workbench for processing the spaceflight empennage sheets, when the spaceflight empennage sheets with different sizes need to be welded and assembled on the top surface of the workbench body, the clamping area of the surfaces of the spaceflight empennage sheets can be changed by replacing the clamping plates arranged on the surfaces of the mounting plates; when the surface of the clamping plate clamps the spaceflight empennage piece, the output pressure of the hydraulic oil cylinder is too large, the moving plate and the clamping plate are moved to directly clamp the spaceflight empennage piece, and therefore the buffering force generated when the clamping plate clamps the surface of the spaceflight empennage piece can be achieved through the elastic force of the reset spring; therefore, extrusion deformation of the surface of the spaceflight empennage caused by overlarge output pressure of the hydraulic oil cylinder is avoided.

Technical Field

[0001] The utility model relates to the technical field of aerospace tail fin processing, in particular to a welding workbench for aerospace tail fin processing. Background Art

[0002] Folding wings will appear in aerospace tail panels. The folding wing design technology has the technical advantage of solving geometric space contradictions in aircraft weapons and equipment, and has been increasingly used.

[0003] However, in the prior art, the aerospace tail fin pieces are welded squarely on the surface of the workbench during welding and assembly, and the workers need help from other personnel when they set up the aerospace tail fin pieces and weld them. In addition, the aerospace tail fin piece structure is more difficult to butt-weld, so it is necessary to clamp it firmly on the top surface of the workbench to facilitate welding by the workers, and when clamping the surface of the aerospace tail fin piece, it is necessary to avoid the clamping force causing its surface to be squeezed and deformed by the clamping plate.

[0004] Therefore, we need a welding workbench for processing aerospace tail fins, which can solve the problem of the clamping plate of the existing aerospace tail fins squeezing and deforming its surface when the aerospace tail fins are firmly welded on the workbench, and can also achieve firm clamping of aerospace tail fins of different sizes when they are welded on the top surface of the workbench. Utility Model Content

[0005] The purpose of the utility model is to provide a welding workbench for processing aerospace tail fins, so as to solve the problem of the existing aerospace tail fins being squeezed and deformed by the clamping plates on their surfaces when they are firmly welded on the workbench, as proposed in the above-mentioned background technology, and to achieve firm clamping of aerospace tail fins of different sizes when they are welded on the top surface of the workbench.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding workbench for processing aerospace tail wing pieces, comprising a workbench body, a movable platform is arranged on the top of the workbench body, a hydraulic cylinder is fixedly connected to the inner surface of the movable platform, a movable plate is fixedly connected to the end of the power output shaft of the hydraulic cylinder, a mounting plate is arranged on the top of the movable plate, and a clamping plate is arranged on the surface of the mounting plate.

[0007] Preferably, a side surface of the movable platform is fixedly connected to a supporting guide rod, and a surface of the supporting guide rod is movably connected to an inner through hole surface of the movable plate.

[0008] Preferably, a card slot is provided on the top surface of the movable plate, the surface of the card slot is engaged with the surface of the card block, the top surface of the card block is fixedly connected with a mounting plate, a rectangular card slot is provided on the side surface of the movable plate, a limiting plug plate is inserted on the surface of the rectangular card slot, and the card slot and the rectangular card slot are connected.

[0009] Preferably, the inner through hole surface of the mounting plate is movably connected to the surface of the moving rod, the end of the moving rod is fixedly connected to the surface of the clamping plate, and the surface of the moving rod is sleeved with a return spring.

[0010] Preferably, a limiting slot is provided on the top surface of the clamping plate, a limiting strip is inserted into the surface of the limiting slot, the surface of the limiting strip is fixedly connected to the inner surface of the rubber pad, and the limiting slot does not completely penetrate the top surface of the clamping plate.

[0011] Preferably, the movable platform is arranged in an "L" shape, two movable platforms are arranged, and the two movable platforms are symmetrically arranged along the center point of the workbench body.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: by starting the hydraulic cylinder, the clamping plate is moved to clamp the aerospace tail wing piece, so that the aerospace tail wing piece is firmly fixed on the top of the workbench body, which is convenient for the workers to weld and assemble it. When aerospace tail wing pieces of different sizes need to be welded and assembled on the top surface of the workbench body, the clamping area on the surface of the aerospace tail wing piece can be changed by replacing the clamping plate arranged on the surface of the mounting plate. When the surface of the clamping plate clamps the aerospace tail wing piece, it will cause the output pressure of the hydraulic cylinder to be too large, and the moving plate and the clamping plate will be directly clamped to the aerospace tail wing piece, so that the buffering force of the clamping plate clamping to the surface of the aerospace tail wing piece can be achieved through the elastic force of the reset spring, thereby avoiding the surface of the aerospace tail wing piece being squeezed and deformed by the excessive output pressure of the hydraulic cylinder; it further solves the problem of the clamping plate squeezing and deforming the surface of the existing aerospace tail wing piece when the aerospace tail wing piece is firmly welded on the workbench, and can also achieve the stable clamping of aerospace tail wing pieces of different sizes when they are welded on the top surface of the workbench.
