Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device that facilitates the fixing of workpieces. Background Technology

[0002] Welding, also known as fusion welding or melting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. During welding, to ensure weld quality, improve welding efficiency, ensure operator safety, and achieve welding automation, various techniques are employed. ， The workpiece needs to be fixed.

[0003] However, when using a fixing mechanism to fix a workpiece, most of these mechanisms can only fix the workpiece when the side of the workpiece is flat. When the side of the workpiece is inclined, different fixing mechanisms need to be used to clamp and fix different workpieces. This process is tedious, complicated, time-consuming and labor-intensive. Therefore, we need to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a welding device that facilitates workpiece fixation. The device includes a clamping plate, a second threaded rod, and a hinged rod. The clamping plate, in conjunction with the hinged rod, can rotate flexibly according to the inclined surface of the workpiece, thereby fitting the side of the workpiece at different inclination angles to achieve stable clamping and improve the stability during welding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-8 A welding device for easy workpiece fixation includes a base plate 1, with an L-shaped mounting plate 2 fixedly connected to the outer wall of the base plate 1. A welding mechanism 3 is mounted on the lower end of the mounting plate 2. The welding mechanism 3 is prior art and will not be described in detail here. This welding device for easy workpiece fixation is suitable for welding most workpieces with inclined or flat sides, and can effectively improve the stability and quality of welding. A groove 4 is provided at the upper end of the base plate 1, and a first threaded rod 5 is rotatably connected between the inner walls of the two sides of the groove 4. The first threaded rod 5 is a bidirectional threaded rod. A first motor 6 is mounted on the outer wall of the base plate 1. The first motor 6 is a servo motor. The output shaft of the first motor 6 extends into the interior of the slide groove 4 and is fixedly connected to one end of the first threaded rod 5. A sliding rod 7 is fixedly connected between the inner walls of both sides of the slide groove 4. Multiple sliders 8 are slidably connected to the inner wall of the slide groove 4. Two sliders 8 are threadedly connected to the two threaded ends of the first threaded rod 5, and the other two sliders 8 are slidably connected to the sliding rod 7. A sliding plate 9 is fixedly connected to the upper end of each pair of cooperating sliders 8. By driving the first threaded rod 5 to rotate through the first motor 6, the two sliding plates 9 can move towards or away from each other, which is convenient for adjusting the distance between them according to the workpieces of different sizes.

[0026] Each of the two sliding plates 9 has two rotating grooves 10. A movable frame 11 is slidably connected to the inner wall of each rotating groove 10. A clamping plate 12 is hinged to the outer wall of each movable frame 11. The clamping plate 12 can fix workpieces with inclined sides, and its inclination angle can be adjusted according to the inclination angle of the workpiece's inclined surface. When the clamping plate 12 is not needed, it can be retracted into the rotating groove 10. A second threaded rod 13 is rotatably connected between the inner walls of both sides of each movable frame 11. Each second threaded rod 13... Each end extends to the outside and is fixedly connected to a knob 14. The knob 14 can be rotated directly to drive the second threaded rod 13. Each second threaded rod 13 is threadedly connected to a moving plate 15. Each moving frame 11 is fixedly connected to the inner walls on both sides of its inner walls. The other side of each moving plate 15 is slidably connected to the corresponding guide rod 16. Each clamping plate 12 is fixedly connected to a connecting block 17 on its side wall. Each moving plate 15 is hinged to two hinge rods 18. The other end of each hinge rod 18 is hinged to the corresponding connecting block 17.

[0027] Rotating the knob 14 drives the second threaded rod 13 to rotate, causing the moving plate 15 to slide along the guide rod 16 within the moving frame 11. This, in turn, drives the clamping plate 12 to rotate via the hinge rod 18, thus clamping the workpiece. This ensures that the workpiece will not shift during welding, guaranteeing welding quality. Each rotating groove 10 has a moving groove 19 at its inner top, and each moving groove 19 has a limit block 20 slidably connected to its inner wall. Each moving frame 11 has multiple limit blocks at its upper end that cooperate with the corresponding limit blocks 20. The upper end of each limiting block 20 is fixedly connected to the groove 21, and the upper end of each limiting block 20 extends to the outside and is fixedly connected to the pull plate. The outer wall of each limiting block 22 is fitted with a spring 23. The two ends of each spring 23 are elastically connected to the inner wall of the corresponding moving groove 19 and the upper end of the limiting block 20, respectively. The moving frame 11 slides in the rotating groove 10, and through the cooperation of the limiting block 20 and the limiting groove 21, the moving frame 11 is fixed in different positions to adapt to the inclined surface of workpieces of different specifications.

[0028] Each of the two sliding plates 9 has a fixed plate 24 fixedly connected to its upper end. A second motor 25, a servo motor, is mounted on the opposite sides of each fixed plate 24. The output shafts of both second motors 25 pass through their respective fixed plates 24 and are fixedly connected to gears 26. Two connecting plates 27 are fixedly connected to the opposite sides of each fixed plate 24. A fixed rod 28 is fixedly connected between each pair of mating connecting plates 27. A rack 29 is slidably connected to each of the two fixed rods 28. Both racks 29 mesh with their corresponding gears 26. Two connecting rods 30 are fixedly connected to opposite sides of strip 29. Both connecting rods 30 are L-shaped, and pressure plates 31 are fixedly connected to the lower ends of both connecting rods 30. The lower ends of both pressure plates 31 are provided with rubber layers. The second motor 25 drives the gear 26 to rotate, causing the rack 29 meshing with the gear 26 to slide on the fixed rod 28, thereby causing the pressure plates 31 to move downward and press the workpiece vertically. The rubber layer increases the friction between the pressure plates 31 and the workpiece, preventing the workpiece from sliding in the vertical direction, and also avoiding damage to the surface of the workpiece caused by the pressure plates 31.

[0029] In this utility model, when it is necessary to adjust the distance between the two sliding plates 9 according to the size of the workpiece, the first motor 6 is started to drive the first threaded rod 5 to rotate, thereby causing the two sliders 8 to move towards or away from each other in the slide groove 4. The other two sliders 8, which are slidably connected to the sliding rod 7, play an auxiliary support and guiding role, thereby causing the two sliding plates 9 to move towards or away from each other to adapt to workpieces of different sizes.

[0030] When the side of the workpiece is inclined, turn the knob 14. The knob 14 drives the second threaded rod 13 to rotate, so that the moving plate 15 slides along the guide rod 16 in the moving frame 11. When the moving plate 15 moves, it drives the clamping plate 12 to rotate through the hinge rod 18 until the clamping plate 12 is in contact with the inclined surface of the workpiece. Then continue to turn the knob 14 so that the clamping plate 12 further clamps the workpiece, ensuring that the workpiece will not be displaced in the horizontal direction during the welding process.

[0031] When it is necessary to fix the movable frame 11 in different positions in the rotating groove 10 to adapt to the inclined surface of workpieces of different specifications, pull the pull plate to drive the pull rod 22 to move upward, the pull rod 22 drives the limit block 20 to move upward, and compresses the spring 23. After the movable frame 11 slides in the rotating groove 10 to the appropriate position, release the pull plate, the spring 23 restores its elastic deformation, pushes the limit block 20 to move downward, so that it is locked into the corresponding limit groove 21, thereby fixing the movable frame 11 in the corresponding position in the rotating groove 10.

[0032] When it is necessary to press the workpiece in the vertical direction, the second motor 25 is started, which drives the gear 26 to rotate, so that the rack 29 meshing with the gear 26 slides on the fixed rod 28, thereby causing the connecting rod 30 to move downward. The connecting rod 30 will drive the pressure plate 31 to move downward, thereby causing the pressure plate 31 to press on the workpiece.

[0033] After the workpiece is firmly fixed between the two sliding plates 9 through the above-mentioned horizontal and vertical fixing operations, the welding mechanism 3 can be activated to perform welding operations on the workpiece. In this way, the workpiece is firmly fixed, ensuring the welding quality.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
