Description

Technical Field

[0001] The utility model relates to the technical field of argon arc welding machines, in particular to an argon arc welding machine with a workpiece positioning and clamping function. Background Technique

[0002] An argon arc welding machine is a machine that uses argon arc welding and adopts a starting arc method of high-voltage breakdown. Argon arc welding is tungsten inert gas shielded arc welding, which refers to a welding method using industrial tungsten or active tungsten as a non-consumable electrode and an inert gas (argon) as a shield.

[0003] For example, an argon arc welding machine with a workpiece positioning and clamping function with the publication number of "CN220805818U". When welding, the weldment to be welded is placed butt-jointed on the roller at the end of the screw rod. Then, rotating the screw rod can drive the pressing plate to extrude the weldment, and the four pressing plates can move independently, so as to realize the fixation of different clamping positions and the centering fixation of asymmetric weldments. After clamping, the screw rod and the sliding rod can ensure the stable position of the weldment, ensuring fast welding and stable clamping. However, when the two workpieces to be welded are tightened, the operator needs to place the workpiece between the two jaws, and then rotate the screw rod to make the pressing plates approach each other to fix the workpiece to be welded. It is very difficult for one operator to complete this work, and the operation is relatively complex. At the same time, after one side of the workpiece is welded, if the other side of the workpiece needs to be welded, the operator needs to remove the workpiece welded on one side and then turn the workpiece over and fix it again, resulting in low working efficiency of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that it is very difficult for one operator to complete the fixation of the workpiece, the operation is relatively complex, the operator needs to remove the workpiece welded on one side and then turn the workpiece over and fix it again to weld the other side of the workpiece, and the working efficiency of the device is low. An argon arc welding machine with a workpiece positioning and clamping function is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an argon arc welding machine with a workpiece positioning and clamping function, including a bottom plate and a vertical plate. The upper end of the bottom plate is fixedly connected to the vertical plate. A rotating structure is arranged above the bottom plate. A fixing structure is arranged inside the two cross plates in the rotating structure. The upper end of the bottom plate is fixedly connected to a first linear slide, and the end of the first linear slide is fixedly connected to a second linear slide. An argon arc welding machine is installed at the lower end of the second linear slide.

[0007] Preferably, the rotating structure includes a double-headed motor. The lower end of the double-headed motor is fixedly connected to the bottom plate. Both ends of the output shaft of the double-headed motor are fixedly connected with first toothed pulleys. The rotating shafts at both ends of the first toothed pulleys are respectively rotationally connected to the vertical plate and the second straight plate through bearings. The first toothed pulley is meshed and connected with a toothed belt. The toothed belt is meshed and connected with a second toothed pulley. The inner wall of the second toothed pulley is fixedly connected to a cylindrical barrel. The cylindrical barrel is rotationally connected to the vertical plate. The ends of the cylindrical barrel are fixedly connected to two cross plates.

[0008] Preferably, a motor is fixedly connected to the inner wall of the cylindrical barrel. First straight plates are fixedly connected to both the inner wall of the cylindrical barrel and the surface of the cross plate.

[0009] Preferably, the output end of the motor is fixedly connected to a threaded rod. Both ends of the threaded rod are rotationally connected to the first straight plate through bearings.

[0010] Preferably, the fixing structure includes a hydraulic cylinder. The hydraulic cylinder is fixedly connected to the box body. The output end of the hydraulic cylinder is fixedly connected to a straight rod. Both ends of the straight rod are slidably connected to the inside of the box body. The straight rod is slidably connected to two first sliders. The first sliders are movably connected to a first connecting rod through pins. The other end of the first connecting rod is movably connected to the inner wall of the box body through a pin. The middle of the first connecting rod is movably connected to a second connecting rod through a pin. The second connecting rod is movably connected to a clamping block through a pin. The clamping block is slidably connected to the box body. Second sliders are fixed to both ends of the box body.

[0011] Preferably, the second sliders are slidably connected to the cross plates. The second slider on one side is threadedly connected to the threaded rod.

[0012] For the argon arc welder with a workpiece positioning and clamping function proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the fixing structure and the staff, when the staff places the workpiece in a suitable position, start the hydraulic cylinder in the corresponding fixing structure. The telescopic end of the hydraulic cylinder extends and drives the straight rod to move leftward. The straight rod moving leftward drives the two first sliders to approach each other. The movement of the first sliders drives the first connecting rod to rotate around the end connected to the box body. The rotation of the first connecting rod drives the second connecting rod to move. The movement of the second connecting rod drives the two clamping plates to approach each other and abut against the workpiece to be welded, fixing the workpiece to be welded. The staff can complete the fixing work alone, and the operation is relatively simple.

[0013] Through the cooperation of the rotating structure and the fixed structure, when one side of the workpiece is welded and it is necessary to weld the other side of the workpiece, start the double-headed motor to drive the first toothed pulleys on both sides to rotate simultaneously. The rotation of the first toothed pulley drives the second toothed pulley to rotate through the toothed belt. The rotation of the second toothed pulley drives the barrel to rotate, the rotation of the barrel drives the cross plate to rotate, and the rotation of the cross plate drives the fixed structure to rotate, turning over the workpiece with one side welded, and then welding the other side of the workpiece. When turning over the workpiece, it is not necessary to remove the workpiece and fix it again, improving the working efficiency of the device. Brief Description of the Drawings

[0030] Working principle:

[0031] The staff first place the two workpieces to be welded between the clamping plates 306 in the fixed structures 3 on both sides to prepare for the welding work.

[0032] Fixing work:

[0033] When the staff place the workpiece in the appropriate position, start the hydraulic cylinder 301 in the corresponding fixed structure 3. The telescopic end of the hydraulic cylinder 301 extends to drive the straight rod 302 to move leftward (as shown in Figure 5 ), the leftward movement of the straight rod 302 drives the two first sliders 303 to approach each other. The movement of the first slider 303 drives the first connecting rod 304 to rotate with the end movably connected to the box body 307 as the center. The rotation of the first connecting rod 304 drives the second connecting rod 305 to move. The movement of the second connecting rod 305 drives the two clamping plates 306 to approach each other and press against the workpiece to be welded, fixing the workpiece to be welded.

[0034] After the workpieces on both sides are fixed, connect the external power supplies of the two motors 5, start the two motors 5 to drive the threaded rods 6 to rotate. The rotation of the threaded rods 6 drives the two second sliders 8 to approach each other. The mutual approach of the second sliders 8 drives the fixing structures 3 to approach each other, thereby driving the two workpieces to be welded to approach each other, causing the two workpieces to be welded to be pressed tightly. Then, through the cooperation of the first linear slide 9 and the second linear slide 10, the position of the argon arc welding machine 10 is adjusted, and the argon arc welding machine 10 is started to weld the workpieces to be welded.

[0035] Turning work:

[0036] When one side of the workpiece is welded and the other side needs to be welded, connect the external power supply of the double-headed motor 201, start the double-headed motor 201 to drive the first toothed belt wheels 202 on both sides to rotate simultaneously. The rotation of the first toothed belt wheels 202 drives the second toothed belt wheels 205 to rotate through the toothed belt 204. The rotation of the second toothed belt wheels 205 drives the cylinder 206 to rotate. The rotation of the cylinder 206 drives the cross plate 207 to rotate. The rotation of the cross plate 207 drives the fixing structure 3 to rotate, turning over the workpiece with one side welded, and then welding the other side of the workpiece.
