Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and more specifically to a carbon dioxide shielded welding machine that is easy to assemble and disassemble. Background Technology

[0002] A carbon dioxide gas shielded welding machine is a type of consumable electrode arc welding equipment that uses carbon dioxide as a shielding gas.

[0003] Chinese utility model patent CN214769579U discloses a wire feeding structure for an automatic wire feeding welding machine, including a winding reel, a wire inlet guide, a fixing frame, a wire outlet guide, and a drive device. The winding reel is rotatably mounted in a receiving cavity, the fixing frame is fixed to the inner wall of the receiving cavity, and the drive device includes an output wheel and a driven wheel. However, in actual use, it has been found that after the welding wire on the reel is used up, the reel needs to be disassembled for replacement. The amount of welding wire remaining mostly depends on the operator opening the welding machine and observing the amount of welding wire remaining, which is a complicated and inconvenient process.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem in existing technologies where observing the remaining amount of welding wire requires opening the welding machine, which is inconvenient, this utility model provides a CO2 shielded welding machine that is easy to assemble and disassemble. The CO2 shielded welding machine includes: a housing with a middle plate and an observation window; a winding reel mounted on the middle plate, with a wire spool detachably mounted on the reel; and a pressure detection structure including a mounting plate mounted on the middle plate, a roller abutting against the welding wire in the wire spool, a test post fixedly connected to the roller and slidably connected to the mounting plate, and a spring sleeved on the test post and abutting against the mounting plate, the spring being configured to push the roller against the wire spool.

[0006] This utility model discloses an easily detachable CO2 shielded welding machine, comprising a housing, a wire reel, and a pressure detection structure. A middle plate is installed inside the housing for mounting the wire feeding structure of the welding machine. An observation window is provided on the housing, allowing observation of the pressure detection structure from the outside. The pressure detection structure includes a mounting plate, a roller, a test post, and a spring. The mounting plate mounts the pressure detection structure onto the middle plate. One end of the test post is connected to the roller. The spring is sleeved on the test post and abuts against the mounting plate, pushing the roller towards the wire reel. As the amount of welding wire in the reel decreases, the roller and test post move towards the wire reel, reducing the length of the test post extending beyond the mounting plate. This allows for convenient measurement of the length of the test post extending beyond the mounting plate, thus determining the amount of welding wire on the reel. Through this design, this easily detachable CO2 shielded welding machine allows for observation of the length of the test post extending beyond the mounting plate inside the housing via the observation window, thereby determining the amount of welding wire on the reel in a simple and convenient manner.

[0007] Furthermore, a limiting cylinder is provided on the mounting plate, and an abutment piece matching the limiting cylinder is provided on the test column; the spring is arranged inside the limiting cylinder and its two ends abut against the limiting cylinder and the abutment piece respectively.

[0008] Furthermore, multiple abutment pieces are arranged at intervals along the circumference of the test column; through holes matching the limiting cylinder are provided on the mounting plate, and limiting pieces are arranged at the through holes; the limiting pieces are configured to allow the spring to pass through the through holes, and openings matching the abutment pieces are formed between the limiting pieces.

[0009] Furthermore, a red marker is provided at the end of the test column furthest from the roller.

[0010] Furthermore, a roller frame is provided between the test column and the roller, the roller frame including a rotating shaft that matches the roller, a mounting column that is connected to the test column, and a connecting column that connects the rotating shaft and the mounting column.

[0011] Furthermore, a connecting plate is provided on the side of the mounting plate near the middle plate, and the connecting plate is fixedly connected to the middle plate by bolts.

[0012] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0013] The pressure testing structure includes a mounting plate, rollers, a test post, and a spring. The mounting plate allows the pressure testing structure to be installed on the middle plate. One end of the test post is connected to the rollers. The spring is sleeved on the test post and abuts against the mounting plate, which pushes the rollers toward the wire reel. As the amount of welding wire in the wire reel decreases, the rollers and test post move toward the winding wheel, reducing the length of the test post extending beyond the mounting plate. This makes it easier to determine the amount of welding wire on the wire reel by observing the length of the test post extending beyond the mounting plate. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of an embodiment of a CO2 shielded welding machine that is easy to assemble and disassemble according to this utility model. Figure 1 As shown, in one or more embodiments, the present invention provides a carbon dioxide shielded welding machine that is easy to assemble and disassemble, comprising a housing 1, a winding reel 2, and a pressure detection structure 3.

[0023] See also Figure 1 The casing 1 is roughly rectangular in shape. Based on Figure 1 In the aforementioned orientation, the housing 1 has opposing front and rear sidewalls. An observation window is provided on the front sidewall, located at its lower right. Furthermore, a middle plate 11 is provided inside the housing 1, dividing the interior of the housing 1 into two parts. The side of the middle plate 11 near the rear sidewall is used to install circuit boards, frequency converters, and other structures; the side of the middle plate 11 near the front sidewall is used to install drive structures, wire feeding devices such as the winding reel 2, and other wire feeding devices. Furthermore, the winding reel 2 is mounted on the middle plate 11, positioned vertically in the middle of the middle plate 11 and horizontally near the right side of the middle plate 11. A wire spool is mounted on the winding reel 2, and the wire spool and the winding reel 2 are fixedly connected by a snap-fit ​​structure.

[0024] Figure 2 This is a schematic diagram of the pressure detection structure in a carbon dioxide shielded welding machine that is easy to assemble and disassemble, according to this utility model. Figure 1 and Figure 2As shown, the pressure detection structure 3 is mounted on the middle plate 11 and arranged on the outer side of the wire reel. In one or more embodiments, the pressure detection structure 3 includes a mounting plate 31 mounted on the middle plate 11, a test column 32 that slides with the mounting plate 31, a roller 33 mounted on the test column 32, and a spring 34 sleeved on the test column 32. Specifically, the mounting plate 31 is generally arc-shaped and arranged on the circumferential outer side of the wire reel. Further, a connecting plate 311 is provided on the side of the mounting plate 31 near the middle plate 11. The connecting plate 311 is attached to the middle plate 11 and is mounted on the middle plate 11 by bolts. Specifically, a through hole is provided on the mounting plate 31 to allow the test column 32 to slide. Further, a limiting piece 312 is provided at the through hole. The limiting piece 312 is generally fan-shaped. Multiple limiting pieces 312 are provided along the circumference of the through hole. For example, two limiting plates 312 are provided circumferentially along the through hole, and the two limiting plates 312 are arranged opposite to each other. The inner diameter of the limiting plate 312 matches the outer diameter of the spring 34, allowing the spring 34 to pass between the two limiting plates 312. An opening is formed between the two limiting plates 312. Further, a limiting cylinder 35 is provided on the mounting plate 31, and the limiting cylinder 35 is arranged on the side of the mounting plate 31 opposite to the winding reel 2. A through hole matching the test post 32 is opened at the end of the limiting cylinder 35 opposite to the mounting plate 31. Specifically, the end of the limiting cylinder 35 opposite to the mounting plate 31 is approximately frustoconical in shape to prevent the test post 32 from deflecting inside the limiting cylinder 35.

[0025] See also Figure 1 and Figure 2 See also Figure 1 and Figure 2The test post 32 is approximately cylindrical, and an abutment piece 321 is provided on the test post 32, extending radially along the test post 32. Further, a red indicator is provided at the end of the test post 32 furthest from the roller 33. When the red indicator approaches the limiting cylinder 35, the welding wire in the coil is nearly exhausted, requiring coil replacement. Further, multiple abutment pieces 321 are provided circumferentially along the test post 32. For example, two abutment pieces 321 are provided, arranged opposite each other, and can disengage from the limiting cylinder 35 through the opening between the limiting pieces 312 during rotation. When coil replacement is required, the test post 32 is pulled downwards and to the right until the abutment piece 321 retracts into the limiting cylinder 35, and the test post 32 is rotated so that the abutment piece 321 abuts against the limiting piece 312, thus limiting the test post 32 to the limiting cylinder 35. A spring 34 is arranged inside the limiting cylinder 35, and its two ends abut against the limiting cylinder 35 and the abutment piece 321 respectively, pushing the abutment piece 321 away from the limiting cylinder 35. Furthermore, a roller frame 36 is provided between the test post 32 and the roller 33. The roller frame 36 includes a rotating shaft 361 that mates with the roller 33, a mounting post 362 connected to the test post 32, and a connecting post 363 connecting the mounting post 362 and the rotating shaft 361. The roller 33 is generally elongated cylindrical and is sleeved on the circumferential outer side of the rotating shaft 361. The length of the roller 33 is less than the thickness of the coil. Two connecting posts 363 are provided, each extending from the end of the rotating shaft 361 to the mounting post 362.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the protection scope of this utility model.
