Description

Technical Field

[0001] This utility model relates to the field of aluminum profile welding, and in particular to an auxiliary positioning device for aluminum profile welding. Background Technology

[0002] Aluminum is a common metal in daily life, and many types of aluminum alloys have been developed. Aluminum alloys have low density but high strength, approaching or exceeding that of high-quality steel. They also have good plasticity and can be processed into various aluminum profiles. Aluminum profiles have excellent electrical conductivity, thermal conductivity, and corrosion resistance. They are widely used in industry, second only to steel in terms of usage. They are one of the most widely used non-ferrous metal structural materials in industry, and are widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding, and chemical industries. The rapid development of the industrial economy has led to an increasing demand for welded aluminum profile structural components, which has also deepened the research on the weldability of aluminum profiles.

[0003] Existing aluminum profile welding auxiliary positioning devices use clamps or similar devices to hold and fix two aluminum profiles. However, these clamps are mostly fixed structures that cannot rotate. In some complex welding scenarios, such as multi-angle splicing and curved surface welding, the auxiliary device needs to be able to rotate flexibly to adapt to different welding requirements. Auxiliary devices that cannot rotate cannot provide effective support in these scenarios, increasing the difficulty and risk of welding.

[0004] Therefore, in view of the problem that existing auxiliary positioning devices cannot adjust the angle by rotation, there is a need for an auxiliary positioning device for welding aluminum profiles that can solve the above problem. Utility Model Content

[0005] In order to solve the problem that the clamps used to fix aluminum profiles cannot rotate in the existing technology, this application provides an auxiliary positioning device for welding aluminum profiles.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An auxiliary positioning device for welding aluminum profiles includes a support plate as a support component. Each support plate has a fixed column fixedly connected to its upper side. Each fixed column has a groove in its middle. Each fixed column has a movable ring movably connected to its outer wall. Each movable ring has a movable groove on its inner side. Each fixed column has a drive assembly inside for driving the movable ring to slide along its outer wall. Each fixed column has a rotating column rotatably connected to its opposite ends. Each rotating column has a toothed ring fixedly connected to its outer wall. Each rotating column has a rotating plate fixedly connected to its opposite ends. Clamping plates for holding aluminum profiles are rotatably connected to the front and rear sides of each rotating plate.

[0008] As a further improvement of this utility model, the driving assembly includes an electric push rod fixedly installed in the middle of the fixed column. Movable plates are movably connected inside the groove. The output end of the electric push rod is fixedly connected to the opposite end of the movable plate. The front and rear ends of the movable plate are movably connected to the inner wall of the movable groove. Fixed blocks are fixedly connected to the upper and lower ends of the movable plate. The outer walls of the fixed blocks are movably connected to the limiting grooves set at the upper and lower ends of the inner side of the groove.

[0009] As a further improvement of this utility model, anti-slip pads are provided on the inner sides of the opposite ends of the clamping plates, and connecting plates are rotatably connected to the outer sides of the opposite ends of the clamping plates. The other ends of the connecting plates are rotatably connected to the front and rear sides of the movable ring, respectively.

[0010] As a further improvement of this utility model, a reduction motor is fixedly connected to each other on the outer wall of the fixed column, and a gear is fixedly connected to the drive shaft of each reduction motor. The outer walls of the gears are respectively meshed with the outer walls of the gear ring.

[0011] As a further improvement of this utility model, a U-shaped plate is fixedly connected to the middle of the opposite ends of the rotating plate, and a bolt is threaded to the top of the U-shaped plate, and a pressure plate is fixedly connected to the bottom of the bolt.

[0015] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0016] 1. In this utility model, the gear is driven by a speed reduction motor to rotate the gear, and the gear, together with the gear ring, drives the clamping plate to rotate slowly. This allows the aluminum profile to be welded from different angles, ensuring the integrity and uniformity of the weld. Whether it is a complex-shaped aluminum profile or a multi-angle spliced ​​structure, the rotation auxiliary device can achieve all-round welding, improving the reliability of the welding.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] Example 1: An auxiliary positioning device for welding aluminum profiles includes a support plate 1 as a support component. A fixed column 2 is fixedly connected to the upper side of the support plate 1. A groove 3 is provided in the middle of each fixed column 2. A movable ring 6 is movably connected to the outer wall of each fixed column 2. A movable groove 7 is provided on the inner side of each movable ring 6. An electric push rod 25 is installed in the middle of the interior of each fixed column 2. A movable plate 4 is movably connected to the interior of each groove 3. The output end of the electric push rod 25 is fixedly connected to the opposite end of the movable plate 4. Both the front and rear ends of the movable plate 4 are movably connected to the inner wall of the movable groove 7. The upper and lower ends of the movable plate 4... Each fixed block 5 is fixedly connected to the inner side of the groove 3 and the upper and lower end of the fixed block 5 are movably connected to the limiting grooves provided at both ends. The opposite ends of the fixed column 2 are rotatably connected to the rotating column 8. The outer wall of the rotating column 8 is fixedly connected to the toothed ring 13. The opposite ends of the rotating column 8 are fixedly connected to the rotating plate 9. The front and rear sides of the rotating plate 9 are rotatably connected to the clamping plate 10 for clamping the aluminum profile. The inner side of the opposite end of the clamping plate 10 is provided with the anti-slip pad 11. The outer side of the opposite end of the anti-slip pad 11 is rotatably connected to the connecting plate 12. The other end of the connecting plate 12 is rotatably connected to the front and rear sides of the movable ring 6 respectively.

[0032] Specifically, the electric push rod 25 is activated to drive the movable plate 4 to slide inside the groove 3. The movable plate 4 drives the movable ring 6 to slide along the outer wall of the fixed column 2. At the same time, the front and rear ends of the movable plate 4 are movably connected to the movable groove 7 set inside the movable ring 6, so that the movable groove 7 can slide along the outer wall of the fixed column 2 or rotate around the fixed column 2. When the movable ring 6 slides along the outer wall of the fixed column 2, it cooperates with the connecting plate 12 to drive the clamping plate 10 to retract, clamping and fixing the aluminum profile, improving the stability of the aluminum profile, and facilitating precise welding by workers.

[0033] Example 2: A grooved plate 20 is fixedly connected to the top center of the support plate 19. A second motor 22 is fixedly connected to the right end of the grooved plate 20. A bidirectional screw 21 is rotatably connected inside the grooved plate 20. The right end of the bidirectional screw 21 is fixedly connected to the drive shaft of the second motor 22. Movable blocks 23 are threadedly connected to both the left and right sides of the outer wall of the bidirectional screw 21. The bottom end of the support plate 1 is fixedly connected to the top of the movable blocks 23.

[0034] Specifically, starting the second motor 22 drives the bidirectional screw 21 to rotate. The rotation of the bidirectional screw 21 drives the movable blocks 23 on both sides to move in opposite directions. The movable blocks 23 drive the support plate 1 and the components fixedly installed on the fixed column 2 to move in opposite directions as a whole, so as to adjust the distance between the two clamping plates 10 as needed, so that the aluminum profiles on both sides fit together. This is suitable for welding aluminum profiles of different sizes and improves the adaptability of the device.

[0035] As one of the optimized structural designs for Example 1, such as Figure 2 and Figure 5As shown, U-shaped plates 16 are fixedly connected to the middle of opposite ends of the rotating plate 9. Bolts 17 are threaded to the top of the U-shaped plates 16, and pressure plates 18 are fixedly connected to the bottom of the bolts 17. By tightening the bolts 17, the pressure plates 18 are driven to move downward, which strengthens the fixation of the aluminum profile and improves the stability of the aluminum profile during welding.

[0036] Working principle: When in use, place the two aluminum profiles to be welded on the inner side of the U-shaped plates 16 on both sides. Tighten the bolts 17 to move the pressure plate 18 downwards to initially fix the aluminum profiles. Start the electric push rod 25, which drives the movable plate 4 to move. The movable plate 4 drives the movable ring 6 to slide along the outer wall of the fixed column 2. The movable ring 6, in conjunction with the connecting plate 12, drives the clamping plate 10 to retract and clamp the aluminum profiles a second time. Start the second motor 22 to drive the bidirectional screw 21 to rotate. The bidirectional screw 21 drives the movable block 23 and all components, including the clamping plate 10, fixed on the upper end of the movable block 23, to move towards the middle, so that the aluminum profiles on both sides are close together. The worker uses a hand-held electric welder to weld the aluminum profiles. During welding, start the reduction motor 14, which drives the gear 15 to rotate. The gear 15, in conjunction with the gear ring 13, drives the rotating column 8, rotating plate 9, and clamping plate 10 to rotate slowly as a whole, which in turn drives the aluminum profiles to rotate slowly, so that the worker can perform 360-degree welding without dead angles.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
