Description

Technical Field

[0001] This utility model relates to the field of sheet metal welding equipment, and in particular to a sheet metal welding equipment for an air conditioner frame. Background Technology

[0002] The main structure of an air conditioner frame is usually made of metal, with sheet metal welding being the most common manufacturing method. This involves cutting materials such as cold-rolled steel sheets, galvanized steel sheets, or aluminum alloy sheets to the design dimensions, pre-treating them by bending and punching, and then welding them together to form the overall frame.

[0003] Sheet metal welding of air conditioner frames mainly relies on arc welding technology, with DC welding machines being one of the core pieces of equipment. DC welding machines convert alternating current (AC) to direct current (DC), providing a stable energy input for the welding arc. They feature stable arc combustion, controllable penetration depth, and minimal spatter, as illustrated by existing technology in Chinese patent publication number "CN218363079U". A welding device for sheet metal manufacturing is provided, including a welding machine body. The welding machine body is provided with a heat dissipation mesh, which is located at the center of the front surface of the welding machine body. The heat dissipation mesh is provided with a protective mechanism, which includes a sliding component and a locking component, and a cable. The cable is installed on the front surface of the welding machine body, and a welding head is provided at the end of the cable. By designing the protective mechanism, a hand-held sliding rod can be used to slide inside the first sliding groove, and the sliding rod will also drive the protective plate to slide. Simultaneously, a slider inside the second sliding groove controls the end of the protective plate, facilitating the closure of the two protective plates on the inner surface of the heat dissipation mesh. After the two protective plates are closed and installed, they are directly and elastically pressed into the inside of the locking groove by the deformation of an elastic locking body, facilitating the closure and fastening of the two protective plates, and making installation and use convenient.

[0004] Currently, the sheet metal welding of most air conditioner frames is often done manually using a handheld DC welding machine because some welding points cannot be processed in one go by large welding equipment. However, conventional welding machines are quite heavy, making them difficult to lift and carry when moving between work areas. Utility Model Content

[0019] 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.

[0020] Reference Figures 1-5A sheet metal welding device for an air conditioner frame includes a base 1. Universal wheels 11 are fixedly distributed at the four corners of the lower end of the base 1. A DC welding machine 12 is erected on top of the base 1. A control panel 13 is embedded in the center of the front of the DC welding machine 12. A positive terminal interface 14 and a negative terminal interface 15 are also fixedly distributed at the lower end of the front of the DC welding machine 12. The control panel 13 has a digital display area and a button area, facilitating the operation and adjustment of the DC welding machine 12. The positive terminal interface 14 and the negative terminal interface 15 are connected to the corresponding positive and negative welding heads for power supply. The DC welding machine 12 can be adjusted to any position via the universal wheels 11. A handle 16 is fixedly installed on the upper end of the DC welding machine 12, and a handle 27 is fixedly installed on the upper end of the base 1. The handle 16 can be used to lift the DC welding machine 12 for movement, and the handle 27 can be used to push the whole unit to move with the casters 11. The DC welding machine 12 has a power interface 18 on its back. The power interface 18 is connected via a power cord to power the DC welding machine 12.

[0021] Among them, a rod seat 2 is fixedly installed at the upper end of the base 1 away from the DC welding machine 12. A winding rod 21 is slidably inserted inside the rod seat 2. The winding rod 21 can wind and store long wires connected to the welding head. The rod seat 2 can ensure the insertion position of the winding rod 21.

[0022] Among them, a number of partition plates 22 are fixedly sleeved on the surface of the winding rod 21, and the partition plates 22 are evenly distributed along the vertical position of the winding rod 21. The partition plates 22 can separate and wind the positive and negative lines connected by the welding head.

[0023] The lower end of the outer wall of the winding rod 21 is fixedly installed with a positioning sleeve 3 by a bracket. The positioning sleeve 3 has a positioning pin 31 that is slidably connected inside. The positioning pin 31 can be slidably adjusted based on the positioning sleeve 3, and it is a manual pull structure.

[0024] The positioning pin 31 is wound with a spring 32. The two ends of the spring 32 are fixedly installed to the end face of the positioning sleeve 3 and the end position of the positioning pin 31, respectively. The spring 32 can ensure the stable extension and resetting of the positioning pin 31.

[0025] The winding rod 21 is fixedly mounted with a positioning seat 33. The end of the positioning pin 31 away from the spring 32 is slidably inserted into the interior of the positioning seat 33. When it is necessary to separate the winding rod 21, the positioning pin 31 is pulled. Through the stretching effect of the spring 32, the positioning pin 31 is separated from the positioning seat 33, which can realize the disassembly of the winding rod 21 and the rod seat 2.

[0026] The DC welding machine 12 has extension plates 4 fixedly installed on both sides. A collar 41 is fixedly installed through the surface of the extension plate 4. A threaded post 42 corresponding to the position of the collar 41 is fixedly installed on the upper end of the base 1. The surface of the threaded post 42 is slidably sleeved with the inside of the collar 41. By connecting the threaded post 42 with the collar 41, the DC welding machine 12 and the base 1 can be quickly positioned and connected.

[0027] The threaded post 42 is threaded with a threaded cap 43 at its end. One side of the threaded cap 43 is tightly fitted against the end face of the collar 41. The threaded cap 43 and the threaded post 42 are threaded together to lock and fix the position of the DC welding machine 12 and the base 1.

[0028] Among them, a connecting seat 5 is slidably inserted into one side of the base 1. Two storage tubes 51 of the same size for placing welding heads are fixedly installed on the surface of the connecting seat 5 by a bracket. The storage tubes 51 can be used to insert and store the welding heads.

[0029] Among them, the upper end of the connecting seat 5 is embedded and fixed with a threaded sleeve 52, and the internal thread of the threaded sleeve 52 is fitted with a threaded knob 53. One end of the threaded knob 53 is tightly attached to the surface of the base 1. The copper drum threaded knob 53 expands and contracts based on the threaded sleeve 52 and is tightly attached to the base 1, so that the position of the connecting seat 5 relative to the base 1 can be fixed.

[0030] Working method: Four casters 11 are installed under the base 1 of this solution. These casters 11 allow the equipment to move flexibly in any direction, which is convenient for quick transfer between different workplaces. A handle 2 17 is fixed on the upper end of the base 1. Users can push the handle 2 17 in conjunction with the casters 11 to achieve smooth movement of the whole equipment. The handle 1 16 on the upper end of the DC welding machine 12 makes it easy to lift the equipment directly for short-distance adjustment or transportation, which enhances the portability and operational flexibility of the equipment. In addition, the DC welding machine 12 achieves initial positioning by sliding the collar 41 on the extension plate 4 with the threaded post 42 on the upper end of the base 1. Then, the end face of the collar 41 is tightly fixed by the threaded installation of the threaded cap 43 and the threaded post 42, thereby ensuring the stable locking of the DC welding machine 12 on the base 1 and preventing displacement or loosening during movement or use. A rod seat 2 is fixedly installed at the upper end of the base 1 away from the DC welding machine 12. The winding rod 21 is slidably inserted into the rod seat 2, allowing the user to adjust the position of the winding rod 21 or disassemble it as needed. Multiple partition plates 22 are fixedly sleeved on the surface of the winding rod 21. These partition plates 22 are distributed vertically at equal intervals, which can separate and wind the welding head lines connected to the positive terminal interface 14 and the negative terminal interface 15, avoiding mutual entanglement or short circuit of the positive and negative terminals, and ensuring the neatness and safety of the lines. A positioning sleeve 3 is installed at the lower end of the outer wall of the winding rod 21 through a bracket. A positioning pin 31 is slidably sleeved inside the positioning sleeve 3. A spring 32 is wound on the surface of the positioning pin 31. The two ends of the spring 32 are fixed to the end face of the positioning sleeve 3 and the end of the positioning pin 31, respectively, to provide telescopic and restoring force. When it is necessary to disassemble the winding rod 21, the user manually pulls the positioning pin 31, and the spring 32 stretches to separate the positioning pin 31 from the positioning seat 33 on the surface of the winding rod 21, thereby realizing the quick removal of the winding rod 21 from the rod seat 2, which is convenient for the maintenance or replacement of the lines. A connecting seat 5 is slidably inserted into one side of the base 1. Two storage tubes 51 are fixedly installed on the surface of the connecting seat 5 by a bracket. These storage tubes 51 are used to store welding heads, preventing them from being damaged or lost due to random placement, and keeping the work area orderly. A fixed threaded sleeve 52 is embedded in the upper end of the connecting seat 5. A threaded knob 53 is installed inside the threaded sleeve 52. By rotating the threaded knob 53, it can move back and forth based on the threaded sleeve 52. When one end of the threaded knob 53 is in close contact with the surface of the base 1, friction is generated to lock the position of the connecting seat 5, preventing it from sliding during equipment movement or use. This adjustable fixing mechanism allows users to adjust the position of the connecting seat 5 and the storage tubes 51 relative to the base 1 according to actual needs. For example, during welding operations, the storage tubes 51 can be placed in an easily accessible position to improve operational convenience.

[0031] 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.
