Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of double-sealed welding machines, and in particular, to a double-sealed welding machine and a welding method for clamp processing. Background Art

[0002] A clamp is a commonly used mechanical component or fastener. Its core function is to fix or connect objects through the clamping force of the ring structure. It is widely used in fields such as construction, machinery, and pipelines. When the clamp needs to be rigidly connected to other components, a welding machine is required to directly weld the workpiece.

[0003] The most widely used welding machine is the two-shielded welding machine. The full name of the two-shielded welding machine is carbon dioxide gas shielded arc welding machine. It is a kind of metal-shielded gas welding machine equipment that uses carbon dioxide as a shielding gas. During the welding process, carbon dioxide gas is sprayed to the workpiece through the nozzle to form a gas hood to isolate the gas and prevent the high-temperature molten pool from being contaminated by oxygen and nitrogen, thereby ensuring the quality of the weld.

[0004] The two-protection welding machine is divided into automatic and semi-automatic. The semi-automatic welding machine places the main unit and carbon dioxide gas tank on a movable plate. When welding, the device is manually pushed to the welding area by the staff, and then the staff holds the welding gun to weld. It has high flexibility. However, since the main unit and gas tank are exposed to the outside world, objects may hit the main unit or gas tank during movement, causing damage, and it may also be kicked by passing staff when placed, causing it to fall over. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of the present disclosure provide a two-protection welding machine and a welding method for clamp processing, which are used to solve the technical problem in the prior art that the main body and gas storage tank of the welding machine are exposed to the outside and are easily damaged.

A stabilizing component is provided on the inner side wall of the protective cover 4 for clamping and fixing the main unit 17 and the gas tank 18 of the welding machine body 1. The moving component is provided on the moving plate 2, for driving the two protective covers 4 to move on the moving plate 2 and the sliding plate 3.

[0025] like Figure 5 and Figure 6 As shown, it should be added that the welding machine body 1 includes a main unit 17, a gas tank 18 and a welding gun 19. The welding gun 19 is connected to the main unit 17 through a cable, and the main unit 17 is connected to the gas tank 18 through a pipe. The gas tank 18 and the main unit 17 are both installed on the movable plate 2, and a universal wheel is installed at the bottom end of the movable plate 2, and a through hole for passing the cable is opened on the side of the protective cover 4.

[0026] like Figure 3 、 Figure 4 and Figure 7As shown, when the mobile device is not in use or is placed, because a placement plate 16 is fixedly installed on the inner wall of one of the protective covers 4, the welding gun 19 and the cable are first placed on the placement plate 16, and then the two protective covers 4 are driven by the moving assembly to move relative to each other to protect the main unit 17 and the gas tank 18 of the welding machine body 1. The moving assembly includes a moving frame 8, a rack 9, a connecting frame 10 and a driving assembly. There are two mobile frames 8, and the two mobile frames 8 are slidably installed in the slide groove of the moving plate 2. There are two racks 9, and the two racks 9 are respectively fixedly installed on the sides of the two mobile frames 8. There are two connecting frames 10, and one end of the two connecting frames 10 is respectively fixedly installed on the sides of the two mobile frames 8, and the other ends of the two connecting frames 10 are respectively They are fixedly installed on the sides of the two protective covers 4, and the driving assembly is arranged at the top of the movable plate 2. The driving assembly includes a driving motor 11, a driving shaft 12, a driving gear 13 and a protective assembly.

The movable plate 2 moves relatively to place the welding machine body 1 into the protective cover 4 for protection. After the two protective covers 4 are attached, the inner wall of the clamping ring 6 is attached to the outer wall of the gas tank 18, and the clamping plate 7 is attached to the side of the main machine 17. After the two protective covers 4 are attached, the two clamping rings 6 clamp and fix the outer wall of the gas tank 18, and the clamping plate 7 is attached to the side of the main machine 17, so as to ensure that the main machine 17 and the gas tank 18 will not easily fall over or tilt during movement.

[0030] Then push the device to the welding area, place the clamp and connector on the workbench, then start the drive motor 11, open the protective cover 4, take out the welding gun 19, and weld by holding the welding gun 19 and the welding rod by the staff. The two-shield welding machine adopts a DC power supply, and the host 17 provides a stable welding current to the welding gun 19 through the cable to make the arc burn stably, and the carbon dioxide released from the gas tank 18 can melt the gas shielded arc welding. The carbon dioxide gas serves as a protective medium to isolate the air from the pollution of the molten pool, and finally form a weld.

[0031] Example 2: Example 2 of the present application is supplemented on the basis of Example 1 and is a welding method for processing a clamp, comprising the following steps: Step 1: Push the welding machine body 1 to the welding area for subsequent welding by pushing the movable frame 8; Step 2: Place the welding gun 19 on the mounting rack inside the protective cover 4. Step 3: Protect the welding body. Before moving, start the drive motor 11. The output end of the drive motor 11 drives the drive shaft 12 to rotate. The drive shaft 12 drives the drive gear 13 to rotate. The drive gear 13 drives the two racks 9 to move in opposite directions. The drive rack 9 drives the moving frame 8 to move on the moving plate 2. Then, driven by the connecting frame 10, the protective cover 4 moves relatively on the sliding plate 3 and the moving plate 2, thereby placing the welding machine body 1 into the protective cover 4 for protection. Step 4: Fix the welding machine body 1. When the two protective covers 4 are fitted together, the two clamping rings 6 can clamp and fix the gas tank 18, and the clamping plate 7 can fit and clamp the side of the main unit 17 of the welding machine body 1, thereby protecting the main unit 17 and the gas tank 18 of the welding machine body 1 from excessive shaking during movement; Step 5: Welding. When the clamp and the connector are pushed to the welding area, the clamp and the connector are placed on the workbench, the protective cover 4 is opened, the welding gun 19 is taken out, and the staff performs welding on the clamp and the connector.
