Description

Technical Field

[0001] This utility model relates to the field of inverter-type DC manual arc welding machine technology, and in particular to an inverter-type DC manual arc welding machine structure. Background Technology

[0002] In existing technology, the inverter-type DC manual arc welding machine is a device that uses inverter technology to convert alternating current (AC) to direct current (DC) for welding. This machine uses inverter technology to convert the three-phase power frequency (50Hz) AC grid voltage into DC power through an input rectifier and filter. Then, through the alternating switching action of high-power switching electronic components (such as SCRs, GTRs, MOSFETs, or IGBTs), the DC power is inverted into medium-frequency AC power ranging from a few kHz to tens of kHz. This type of welding machine is suitable for various applications requiring DC welding, such as welding carbon steel, stainless steel, and cast iron. Due to its high efficiency and energy-saving characteristics, the inverter-type DC manual arc welding machine has been widely used in industrial production. However, existing inverter-type DC manual arc welding machines suffer from low stability during use, are inconvenient to install, and are difficult to adjust according to usage conditions.

[0003] Therefore, this application proposes an inverter-type DC manual arc welding machine structure to solve the above-mentioned problems. Utility Model Content

The L-shaped plates are symmetrically fixedly connected to the top of the contact plate, the two pull plates are rotatably connected to the top of the adjacent L-shaped plates, and the positioning plates are symmetrically slidably connected to the top of the movable seat. The tops of the two positioning plates are rotatably connected to the left side of the pull plates.

[0006] As a preferred embodiment of this utility model, an auxiliary plate is fixedly connected to the left side of the inverter-type DC manual arc welding machine, and the auxiliary plate is in movable contact with two positioning plates.

When the contact plate moves, it can synchronously drive the L-shaped plate to move to the right. 2. As the L-shaped plate moves, it can pull the pull plate to move as well. When the pull plate moves, it can pull the two positioning plates closer to each other. At this time, the positioning plates can contact the top of the auxiliary plate, restricting the movement of the inverter DC manual arc welding machine. At the same time, when the locking plate is matched with the locking hole, the second spring can push the locking plate down. At this time, the locking plate can connect with the locking hole, ensuring the stability of the inverter DC manual arc welding machine installation. 3. As the contact plate moves, it drives the rack and gear to mesh. At this time, the motor is controlled to work. The output shaft of the motor can control the gear to rotate, thereby controlling the rack to rise. The movement of the rack can synchronously drive the movable seat to rise, thereby controlling the adjustment of the inverter DC manual arc welding machine, which is convenient to use.

[0012] In this invention: by inserting the inverter-type DC manual arc welding machine into the connecting box, the contact plate can be moved. When the contact plate moves, it can assist the positioning plate in moving, thereby fixing the inverter-type DC manual arc welding machine. At the same time, it guides the rack and gear to mesh, and the motor is controlled to work. The motor can assist the rack in rising, and the movement of the rack can synchronously drive the movable seat to rise, thereby controlling the inverter-type DC manual arc welding machine for adjustment, making it convenient to use.

The positioning plates 10 are symmetrically slidably connected to the top of the movable seat 2, and the top of the two positioning plates 10 are rotatably connected to the left side of the pull plate 9.

[0017] With the above structure: by setting up the movable seat 2, the movable seat 2 serves to support the connecting box 5. When the movable seat 2 moves, the movable seat 2 can control the inverter DC manual arc welding machine 3 to move and adjust through the connecting box 5.

[0018] As a preferred embodiment of this utility model, an auxiliary plate 4 is fixedly connected to the left side of the inverter-type DC manual arc welding machine 3, and the auxiliary plate 4 is in contact with two positioning plates 10. When the positioning plate 10 contacts the top of the auxiliary plate 4, the positioning plate 10 fixes the auxiliary plate 4, thereby completing the installation of the inverter-type DC manual arc welding machine 3.

[0019] As a preferred embodiment of this utility model, a rack 13 is fixedly connected to the right side of the contact plate 6, and a first spring 7 is fixedly connected to the left side of the contact plate 6. One end of the first spring 7 is fixedly connected to the right side of the connecting box 5. By setting the first spring 7, the first spring 7 assists the contact plate 6 to return to its original position. At the same time, the movement of the contact plate 6 can control the movement of the rack 13.

[0020] As a preferred embodiment of this utility model, a locking plate 12 is slidably connected to the side of each of the two positioning plates 10 that are far apart from each other. Two locking holes are symmetrically provided on the top of the movable seat 2. The locking plate 12 is movably connected to the locking hole. A second spring 11 is fixedly connected to the top of each of the two locking plates 12. One end of each second spring 11 is fixedly connected to the bottom of the adjacent positioning plate 10. When the locking plate 12 is adapted to the locking hole, the second spring 11 can control the locking plate 12 to descend and connect with the locking hole.

[0021] As a preferred embodiment of this utility model, a motor 14 is fixedly connected to the top of the base 1, and a gear 15 is fixedly connected to the output shaft of the motor 14.

As the inverter-type DC manual arc welding machine 3 moves, it can contact the contact plate 6, simultaneously pushing the contact plate 6 to the right. When the contact plate 6 moves, it can synchronously drive the L-shaped plate 8 to move to the right. As the L-shaped plate 8 moves, it can pull the pull plate 9 to move. When the pull plate 9 moves, it can pull the two positioning plates 10 closer together. At this time, the positioning plates 10 can contact the top of the auxiliary plate 4, restricting the inverter-type DC manual arc welding machine. The movement of the DC manual arc welding machine 3, along with the movement of the locking plate 12 and the locking hole, allows the second spring 11 to push the locking plate 12 downwards. At this time, the locking plate 12 can connect with the locking hole, ensuring the stability of the inverter DC manual arc welding machine 3 during installation. Simultaneously, as the contact plate 6 moves, it can drive the rack 13 to mesh with the gear 15. At this time, the motor 14 is controlled to work, and the output shaft of the motor 14 can control the gear 15 to rotate, thereby controlling the rack 13 to rise. The movement of the rack 13 can synchronously drive the movable seat 2 to rise, thereby controlling the inverter DC manual arc welding machine 3 for adjustment, making it convenient to use.
