Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a semi-automatic argon arc welding machine. Background Technology

[0002] Argon arc welding, also known as argon gas shielded welding, is a welding technique that uses argon gas as a shielding gas. Based on the principle of ordinary electric arc welding, it utilizes the protective effect of argon gas on the metal welding material. A high current melts the welding material into a liquid state on the substrate, forming a molten pool, ultimately achieving a metallurgical bond between the weld metal and the welding material. Its core principle lies in the use of argon gas to create a protective gas layer around the arc welding area, completely isolating the weld zone from air and effectively preventing oxidation of the weld metal due to contact with oxygen.

[0003] However, in practice, argon arc welding mostly relies on operators holding the welding torch, and the welding effect is significantly affected by the operator's working condition, resulting in considerable instability in welding quality. For example, operators are prone to hand fatigue and trembling after prolonged operation, which can cause deviations in the relative position of the welding torch and the workpiece, resulting in uneven molten pool formation. If the grip strength is unstable during welding, the arc length may fluctuate, affecting the consistency of the penetration depth. In addition, deviations in the operator's control of the welding angle, fluctuations in the speed of movement, or inconsistent arc dwell time due to lack of concentration can all directly cause defects such as irregular weld formation, undercut, and incomplete penetration. In severe cases, it can even affect the mechanical properties of the welded joint, making it impossible to meet the expected welding quality requirements. Utility Model Content

[0015] 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.

[0016] Please see Figures 1 to 3 This utility model provides a technical solution: a semi-automatic argon arc welding machine, including a processing table 1. The upper surface of the processing table 1 is provided with a first mounting plate 4 that can move back and forth. A first fixing rod 5 is fixedly connected to the center of the right side of the first mounting plate 4. Therefore, when the first mounting plate 4 moves back and forth, it will drive the first fixing rod 5 to move synchronously. A second fixing rod 9 that can move up and down is provided at the end of the first fixing rod 5 away from the first mounting plate 4. A third fixing rod 11 that can rotate is provided at the bottom end of the second fixing rod 9. A welding gun clamping component is provided at the end of the third fixing rod 11 away from the second fixing rod 9. A pressure plate 8 that can move up and down is provided directly above the processing table 1. A support frame 2 is fixedly connected to the upper surface of the processing table 1, and a lead screw slide 3 is fixedly connected to the upper surface of the support frame 2. The bottom end of the first mounting plate 4 is fixedly connected to the slide of the lead screw slide 3 perpendicular to the ground. The lead screw slide 3 is existing technology, and its working principle will not be described in detail. At the same time, when the lead screw slide 3 is working, it can drive the first mounting plate 4 to move back and forth.

[0017] Please see Figures 1 to 2A second clamp 16 is fitted onto the end of the first fixing rod 5 away from the first mounting plate 4, and a second bolt 17 is threaded onto the end of the second clamp 16 away from the first mounting plate 4. The second clamp 16 is a single-ear clamp as used in the prior art. When the operator rotates the second bolt 17, one end of the second clamp 16 will tighten or loosen accordingly. When tightened, the second clamp 16 can be firmly fixed on the first fixing rod 5. When loosened, it can slide and rotate easily on the first fixing rod 5. The outer circumferential surface of the second clamp 16 is fixedly connected to the second mounting plate 20, and the second fixing rod 9 is slidably connected to the second mounting plate 20. Therefore, when the second clamp 16 moves or rotates on the first fixing rod 5, it will cause the second mounting plate 20 to undergo corresponding displacement changes, and the second fixing rod 9 will move synchronously with the second mounting plate 20.

[0018] Please see Figures 1 to 3 A limiting rack 14 is fixedly connected to the outer circumferential surface of the second fixing rod 9 along the axial direction of the second fixing rod 9. A first bolt 15, with one end inserted into the second mounting plate 20, is threaded onto one side of the second mounting plate 20. A limiting block 19 is rotatably connected to the end of the first bolt 15 near the limiting rack 14. The limiting block 19 is slidably connected within the second mounting plate 20, and the side of the limiting block 19 near the limiting rack 14 has teeth that can engage with the limiting rack 14. Therefore, when a person rotates the first bolt 14... At 5 o'clock, the limiting block 19 can move left and right within the second mounting plate 20: when the limiting block 19 moves to the right to the designated position, the teeth on it disengage from the limiting rack 14, and the second fixing rod 9 can slide on the second mounting plate 20. At the same time, the setting of the limiting rack 14 can restrict the second fixing rod 9 from rotating on the second mounting plate 20. When the limiting block 19 moves to the left to the designated position, the teeth on it will engage with the limiting rack 14, thereby restricting the second fixing rod 9 from sliding on the second mounting plate 20.

[0019] Please see Figures 1 to 2 The bottom end of the second fixing rod 9 is fixedly installed with a first clamp 10. An auxiliary mounting plate is fixedly connected to the outer circumferential surface of the first clamp 10, and the bottom end of the second fixing rod 9 is fixedly connected to the auxiliary mounting plate. Therefore, when the second fixing rod 9 moves, the first clamp 10 can be moved synchronously through the auxiliary mounting plate. The third fixing rod 11 is inserted into the first clamp 10, and the end of the first clamp 10 away from the welding gun clamping component is threadedly connected with a third bolt 18. The first clamp 10 adopts a single-ear clamp in the prior art. When the third bolt 18 is rotated, one end of the first clamp 10 can be tightened or loosened. When one end of the first clamp 10 is loosened, the third fixing rod 11 can slide and rotate on the first clamp 10. When one end of the first clamp 10 is tightened, the third fixing rod 11 is fastened and limited on the first clamp 10.

[0020] Please see Figures 1 to 2The welding torch clamping component includes a main extrusion stabilizing plate 12 fixedly connected to a third fixing rod 11. A stabilizing screw 13 is fixedly connected to one end of the main extrusion stabilizing plate 12. A secondary extrusion stabilizing plate is slidably connected to the end of the stabilizing screw 13 away from the main extrusion stabilizing plate 12, and a clamping nut is threadedly connected to the end of the stabilizing screw 13 away from the main extrusion stabilizing plate 12. The opposing surfaces of the main extrusion stabilizing plate 12 and the secondary extrusion stabilizing plate are both provided with slots for fixing the welding torch. Rotating the clamping nut can both drive the secondary extrusion stabilizing plate closer to the main extrusion stabilizing plate 12 and allow space for it to move away—when the secondary extrusion stabilizing plate is close to the main extrusion stabilizing plate 12, it can clamp the welding torch; when the secondary extrusion stabilizing plate is away from the main extrusion stabilizing plate 12, it is easy to remove the welding torch. Furthermore, a limiting sliding rod is fixedly connected to the top of the secondary extrusion stabilizing plate near the main extrusion stabilizing plate 12. One end of the limiting sliding rod passes through the main extrusion stabilizing plate 12 and forms a sliding engagement with it. By setting the limiting sliding rod, the rotation of the secondary extrusion stabilizing plate on the stabilizing screw 13 can be effectively restricted, thereby ensuring its motion stability.

[0021] Two third mounting plates 6 are fixedly connected to the right side of the support frame 2. Cylinders 7 are fixedly connected to the lower surfaces of the two third mounting plates 6. The upper surface of the pressure plate 8 is fixedly connected to the drive rod of the cylinder 7. Therefore, when cylinder 7 is working, it will cause pressure plate 8 to abut against processing table 1, at which time the material to be welded can be clamped and fixed between pressure plate 8 and processing table 1. By adjusting the position of second clamp 16 on first fixed rod 5, the position of second fixed rod 9 on second mounting plate 20, and the position of third fixed rod 11 on first clamp 10, the three-dimensional angle of welding torch can be changed. At the same time, when lead screw slide 3 is working, it can drive welding torch to move back and forth to complete material welding.

[0022] In summary, when using this semi-automatic TIG welding machine, the material to be welded is first placed on the processing table 1. The cylinder 7 is activated to lower the pressure plate 8, which then clamps the material against the processing table 1. Subsequently, by adjusting the sliding and rotation of the second clamp 16 on the first fixed rod 5, the raising and lowering of the second fixed rod 9 on the second mounting plate 20, and the sliding and rotation of the third fixed rod 11 within the first clamp 10, the three-dimensional angle of the welding torch is precisely adjusted to align it with the welding position. Finally, rotating the compression nut securely clamps the welding torch, and activating the screw slide 3 moves the welding torch back and forth, completing the automated welding operation. The overall operation is convenient and flexible, adaptable to different welding needs through multi-dimensional adjustments, balancing clamping stability and welding accuracy, and effectively improving the efficiency of semi-automatic welding.

[0023] 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.
