Description

Technical Field

[0001] The present application relates to the technical field of argon arc welders, and in particular to an argon arc welder that is convenient to carry. Background Technique

[0002] Argon arc welding technology is based on the principle of ordinary arc welding. By using argon to protect the metal welding material, a high current is used to melt the welding material into a liquid state on the base material to be welded to form a molten pool, enabling metallurgical bonding between the base metal and the welding material. Since argon is continuously supplied during high-temperature melting welding, the welding material cannot come into contact with oxygen in the air, thus preventing oxidation of the welding material. Therefore, stainless steel, iron and other metal hardware can be welded.

[0003] Regarding the above related technologies, the inventor believes that the existing argon arc welder is provided with a handle on the top. The argon arc welder is manually lifted by the handle for carrying. Due to the relatively large weight of the argon arc welder, manual handling is not easy and it is easy to cause bumps to the argon arc welder when manually placing it, which is likely to damage the argon arc welder. Therefore, an argon arc welder that is convenient to carry is proposed to solve the above problems.

[0004] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the present application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0005] In order to solve the above problems, the present application provides an argon arc welder that is convenient to carry.

[0006] The argon arc welder provided by the present application adopts the following technical solutions:

An argon arc welder body is placed on the outer wall of the installation groove. Inner grooves are provided on the outer walls of both sides of the mounting seat. A bidirectional lead screw is rotatably connected to the outer wall of the inner groove. Two first connection seats are symmetrically thread sleeved on the outer wall of the bidirectional lead screw. A chassis is provided below the bidirectional lead screw. A groove is provided on the outer wall of the chassis. A sliding rod is fixedly connected to the outer wall of the groove. Two second connection seats are symmetrically slidably connected to the outer wall of the sliding rod. An articulated frame is provided between the two second connection seats and the two first connection seats, and the articulated frame is hingedly connected to the two first connection seats and the two second connection seats. Two moving wheels are fixedly connected to the bottom outer wall of the chassis.

[0008] Preferably, a drive box is fixedly connected to the side outer wall of the mounting seat. The two bidirectional lead screws rotate through to the inside of the drive box and are fixedly connected to two worm wheels. A worm is rotatably connected to the outer wall of the drive box on one side of the two worm wheels, and the worm meshes with the two worm wheels.

[0009] Preferably, a push rod is fixedly connected to the outer wall of the mounting base facing away from the drive box.

[0010] Preferably, a plurality of support legs are fixedly connected to the bottom outer wall of the mounting base.

[0011] Preferably, a servo motor is fixedly connected to the side outer wall of the drive box, and the output shaft of the servo motor is fixedly connected to the worm.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] By providing the bidirectional lead screw, driving the bidirectional lead screw to rotate, so that the bidirectional lead screw drives the first connecting seats on both sides to move towards each other or in opposite directions, so that the two first connecting seats drive the two second connecting seats to move synchronously through the hinge frame. At the same time, the hinge frame and the second connecting seat drive the chassis to contract or descend. When carrying, the chassis is lowered so that the moving wheels on the chassis contact the ground, thereby facilitating the handling of the argon arc welder. Compared with the prior art, it can facilitate the handling of the argon arc welder more easily, saving time and effort and reducing the labor intensity of workers. At the same time, when the argon arc welder is working, the moving wheels can also contract, so that the support legs can better support the device, thereby improving the working stability of the device.

An articulated frame 17 is arranged between the two first connecting seats 4 and the two second connecting seats 8 in an articulated connection. Through the movement of the two first connecting seats 4, the first connecting seat 4 drives the two second connecting seats 8 below to slide along the trajectory of the slide bar 7 through the articulated frame 17. Through the characteristics of the articulated frame 17, the articulated frame 17 and the second connecting seat 8 drive the base frame 5 to rise or fall. Two moving wheels 9 are fixedly connected to the bottom outer wall of the base frame 5. When the argon arc welding machine needs to be transported, the base frame 5 is lowered so that the two moving wheels 9 on the base frame 5 contact the ground, thereby facilitating the transportation of the argon arc welding machine.
