Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal welding technology, specifically to a welding fixture for assembling metal components. Background Technology
[0002] Metal welding is a manufacturing or sculpting process that joins metals together. During welding, the workpiece and the solder may or may not melt, forming a weld seam that directly connects the materials.
[0003] Currently, in the assembly process of security windows for doors and windows, square outer frame crossbars are welded to round metal rods. During welding, some square crossbars have holes for inserting the round metal rods, while others do not. During welding, the assembly personnel need to align the round metal rod with the square metal rod and hold it while using a welding torch. If there are holes, the operation is easier; otherwise, displacement between the two components is more likely during operation, and tilting may occur after welding. While the holes limit the position, tilting can still occur during welding. In conclusion, we believe that the main reason for the low processing efficiency is the excessive instability caused by manual support during welding, which easily affects welding quality.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Please see Figures 1 to 6 This utility model provides a technical solution: a metal component assembly and welding fixture, including a workbench 1, a fixing block 9 fixedly installed on the top of the workbench 1, a sliding groove 10 opened on one side of the fixing block 9, a screw 24 rotatably connected inside the sliding groove 10, the screw 24 and the fixing block 9 connected by a bearing, a motor 6 fixedly installed on one side of the fixing block 9, a controller provided on the motor 6, the output end of the motor 6 connected to one end of the screw 24 through a coupling, a moving block 23 threadedly connected to the outside of the screw 24, the moving block 23 slidably connected to the sliding groove 10, a device box 7 fixedly installed on one side of the moving block 23, a rotating shaft 15 rotatably connected inside the device box 7 through a bearing, a gear 11 fixedly installed on the outside of the rotating shaft 15, a rack 12 slidably connected to the top of the inner cavity of the device box 7, the rack 12 meshing with the gear 11, one side of the rack 12 extending to the outside of the device box 7 and fixedly connected to a mounting block 5.
[0022] A U-shaped frame plate 4 is fixedly installed on the top of the workbench 1. An electric telescopic rod 3 is fixedly installed on one side of the inner cavity of the U-shaped frame plate 4. A stop plate 2 is fixedly installed at the output end of the electric telescopic rod 3. A sliding groove 25 is opened on one side of the inner cavity of the U-shaped frame plate 4. A slider 26 is fixedly installed on one side of the stop plate 2. The slider 26 is slidably connected to the sliding groove 25. A placement hole 21 is opened on one side of the mounting block 5. The stop plate 2 is moved by the electric telescopic rod 3. Through the cooperation of the stop plate 2 and the U-shaped frame plate 4, the device can fix the metal components.
[0023] A scale plate 8 is fixedly installed on the top of the fixed block 9, and a scale pointer 22 is fixedly installed on one side of the device box 7. The scale pointer 22 cooperates with the scale plate 8. Through the cooperation of the scale plate 8 and the scale pointer 22, the accuracy of the worker's position when welding metal components is improved.
[0024] A mounting box 28 is fixedly installed on one side of the device box 7. One end of the rotating shaft 15 passes through the mounting box 28 and a knob 16 is fixedly installed thereon. The rotating shaft 15 is rotatably connected to the mounting box 28. A ratchet 27 is fixedly installed on the outside of the rotating shaft 15. The ratchet 27 is located inside the mounting box 28. A shaft is fixedly connected inside the mounting box 28, and a pawl 31 is rotatably installed on the surface of the shaft. The pawl 31 cooperates with the ratchet 27, and a torsion spring is provided between the pawl 31 and the shaft. The torsion spring causes the pawl 31 to tilt to the right and engage with the ratchet 27, so that the gear is fixed after rotation. This also makes the connection between the metal components stable and does not wobble, reducing the impact on the welding effect.
[0025] A lead screw protective sleeve is provided on the outside of the screw 24 to prevent dust from getting on the surface of the screw 24 and thus affecting its use.
[0026] A pull rope 30 is fixedly installed on one side of the pawl 31. One end of the pull rope 30 extends to the outside of the mounting box 28 and is fixedly installed with a pull ring 29. The pull ring 29 on the pull rope 30 makes it convenient for workers to control the pawl 31.
[0027] In summary, this metal component assembly and welding fixture is used by workers who connect the power supply to the electric telescopic rod 3 and the motor 6. The square metal component block is placed between the support plate 2 and the U-shaped frame plate 4. The electric telescopic rod 3 has a remote control component installed inside and is controlled by an external controller. Activating the electric telescopic rod 3 pushes the support plate 2, causing it to contact one side of the square metal component block. Then, the worker inserts the circular metal component tube into the placement hole 21 on the mounting block 5. Based on the distance between the connection point of the circular metal component tube and the square metal component block and the bottom of the square metal component, the device box 7 is moved. The motor 6 is activated, causing the screw 24 to rotate. The screw 24 is threadedly connected to the moving block 23. Finally, the worker follows the markings on the device box 7. The needle 22, in conjunction with the scale plate 8, adjusts the circular metal component tube to the appropriate position. Then, the worker turns the knob 16, causing the gear 11 to rotate. The meshing of the gear 11 with the rack 12 causes the rack 12 to move, thereby moving the mounting block 5. When the circular metal component tube contacts the square component block, and with the cooperation of the ratchet 27 and the pawl 31, the circular metal component tube stops wobbling after contact with the square component block. Next, the worker uses welding tools to connect the metal component joints for welding. When welding multiple circular metal component tubes, the worker uses the pull ring 29 on the pull rope 30 to prevent the pawl 31 from contacting the ratchet 27, and rotates the rotating shaft 15 in the opposite direction, causing the rack 12 to return to its initial position. Then, the above operation is repeated.
[0028] 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.
