Description

Technical Field

[0001] The utility model belongs to the field of welding processing devices, in particular to a multi-dimensional working platform for welding a titanium alloy heat exchanger shell. Background Art

[0002] Titanium alloy materials are widely used in aerospace, weapons and equipment, medical equipment and other fields due to their ultra-high specific strength, excellent heat resistance and good corrosion resistance. Among the many workpieces made of titanium alloy materials, titanium alloy heat exchangers are the core components of the power and environmental control systems of high-end marine and aerospace equipment. Their design and manufacturing level restricts the improvement of the power system of major national equipment.

[0003] The plate-fin radiator is basically composed of fins, partitions, seals, guide vanes and other parts. The fins are placed between the partitions, and the guide vanes and seals are added to form a sandwich. Many sandwiches are brazed together according to different ways of fluid circulation to form a plate bundle, and finally assembled inside the shell. Since the plate-fin radiator has a complex internal structure, the flow and heat transfer analysis of the internal fluid is relatively complex, which makes the design and welding of its shell difficult. In particular, some heat exchanger shells with special structures and complex shapes cannot be fully automated if they are only welded by multi-axis robots. Some areas with poor accessibility of welding robots can only be welded manually, resulting in poor weld formation, low welding efficiency, and the inability to effectively guarantee the uniformity of the microstructure and performance of the welded joint, which threatens the safety of the heat exchanger in service. Utility Model Content

[0004] In view of this, the utility model aims to propose a multi-dimensional working platform for welding titanium alloy heat exchanger shells, so as to solve the problem that the existing titanium alloy heat exchanger shell welding method cannot meet the automation requirements.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-dimensional working platform for welding titanium alloy heat exchanger shell, which includes a three-dimensional platform, a platform clamp, a universal joint and an adjustment column foot, the bottom of the three-dimensional platform is connected to the platform clamp, the bottom of the platform clamp is connected to one end of the universal joint, and the other end of the universal joint is connected to the adjustment column foot.

[0006] Furthermore, there are multiple three-dimensional platforms, and the multiple three-dimensional platforms are used in combination through adjustment of platform fixtures, universal joints and adjustable column feet.

[0007] Furthermore, the three-dimensional platform is composed of four pieces, the sides of the four three-dimensional platforms are connected to each other, and the top surface of the three-dimensional platform is arranged horizontally.

[0008] Furthermore, the three-dimensional platform is composed of four pieces, the sides of the four three-dimensional platforms are connected to each other, and there is an angle between the top surface of the three-dimensional platform and the horizontal plane.

[0009] Furthermore, the three-dimensional platforms are four pieces, and the four three-dimensional platforms are connected in pairs, and there is an angle between two groups of three-dimensional platforms.

[0010] Furthermore, the adjusting column foot is a hydraulic adjustment structure.

[0011] Furthermore, the platform fixture is connected to the bottom center of the three-dimensional platform.

[0012] Furthermore, the platform fixture is connected to a non-center portion of the bottom of the three-dimensional platform.

[0013] Furthermore, a plurality of mounting holes are provided on the surface of the three-dimensional platform.

[0014] Furthermore, the movable angle of the universal joint is 270°.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model designs a multi-dimensional working platform for welding titanium alloy heat exchanger shells for heat exchanger shells with complex shapes, and cooperates with the multi-axis movement of the welding robot to finally realize the fully automated welding of the titanium alloy heat exchanger shells, effectively ensuring the safety performance of the heat exchanger in service and improving the welding production efficiency.

[0016] The support and height can be adjusted by adjusting the column feet. The angle can be adjusted through the linkage of the universal joint with the platform fixture and the three-dimensional platform with a hemispherical movable range of 270°. The workpiece on the three-dimensional platform can be movably installed, so that the workpiece, the welding wire in the welding gun and the laser gun head can be adjusted at will to have a fixed angle, height and position; achieving a practical effect of multi-modularization, multi-angle and multi-position. Such a spatial position setting can not only avoid physical interference with each other, but also effectively ensure weld identification, molten pool tracking feedback effect, laser and arc eutectic pool, and easier liquid bridge transition mode between molten pool and welding wire during the welding process, so as to cope with various complex welding situations in a simple adjustment method, thereby ensuring welding efficiency and quality.

The bottom of the three-dimensional platform 1 is connected to the platform fixture 2, the bottom of the platform fixture 2 is connected to one end of the universal joint 3, and the other end of the universal joint 3 is connected to the adjusting column foot 4.

[0027] like Figure 1As shown, the workpiece is mounted on the surface of the three-dimensional platform 1, and the column foot 4 is adjusted to provide support and can adjust the height. The angle is adjusted by the universal joint 3 with a hemispherical range of 270° in conjunction with the platform fixture 2 and the three-dimensional platform 1. The angle of the three-dimensional platform 1 is adjusted by the universal joint 3, the height of the three-dimensional platform 1 is adjusted by adjusting the column foot 4, and the position of the three-dimensional platform 1 is adjusted by the platform fixture 2, so that the workpiece and the welding wire and laser gun head in the welding gun can be adjusted to a fixed angle, height, and position at will. A practical effect of multi-modularization, multi-angle, and multi-position is achieved. Such a spatial position setting can not only avoid physical interference with each other, but also effectively ensure weld identification during welding, molten pool tracking feedback effect, laser and arc eutectic pool, and easier liquid bridge transition mode between molten pool and welding wire, etc., so as to cope with various complex welding situations in a simple adjustment manner, thereby ensuring welding efficiency and quality. As Figure 4 As shown, the angle and installation position of each module can be adjusted arbitrarily during use.

[0028] like Figure 2 and 3 As shown, the number of the three-dimensional platforms 1 is multiple, and the multiple three-dimensional platforms 1 are used in combination through the platform fixture 2, the universal joint 3 and the adjustment column foot 4. Specifically, the three-dimensional platform 1 is four pieces, the sides of the four three-dimensional platforms 1 are connected to each other, and the top surface of the three-dimensional platform 1 is set horizontally.

[0029] like Figure 5 As shown, the three-dimensional platform 1 is composed of four pieces, the sides of the four three-dimensional platforms 1 are connected to each other, and there is an angle between the top surface of the three-dimensional platform 1 and the horizontal plane. The three-dimensional platform 1 can hover at multiple angles, and multiple three-dimensional platforms 1 cooperate with each other to meet the automated welding requirements of different workpieces, with a wider range of uses and more flexible adjustment methods.

[0030] like Figure 6 As shown, the three-dimensional platform 1 is composed of four pieces, and the four three-dimensional platforms 1 are connected in pairs, and there is an angle between two groups of three-dimensional platforms 1. This method can be applied to workpieces with special shapes and can also be used in working environments with uneven ground.

[0031] Preferably, in the above-mentioned embodiment, the adjusting column foot 4 is a hydraulic adjustment structure, which is conducive to the rapid and accurate adjustment of the adjusting column foot 4 by hydraulic adjustment, and has better support.
