Description

Technical Field

[0001] This utility model relates to the field of welding machine technology, and in particular to a welding machine that facilitates the disassembly and replacement of the welding head. Background Technology

[0002] In modern industrial production, welding is a key processing technology widely used in many fields such as machinery manufacturing, automotive industry, and electronics. With the continuous improvement of production efficiency and welding quality requirements, the flexibility, convenience and stability of welding equipment are becoming increasingly important.

[0003] Regarding the installation of welding heads, some existing welding machines use bolts to fix the welding head to the welding torch. This method requires multiple tightening operations using tools such as wrenches, making the installation process cumbersome and time-consuming. In scenarios where frequent welding head replacement is required, such as batch welding on a production line, auxiliary tools like wrenches also need to be searched for, affecting the efficiency of welding head replacement. Other welding machines use an integrated structure where the welding head and welding torch are not detachable. When the welding head is worn or damaged, the entire welding torch must be replaced, increasing maintenance costs and equipment downtime. Therefore, we have introduced a new welding machine that allows for easy disassembly and replacement of the welding head. Utility Model Content

[0004] The main objective of this invention is to provide a welding machine that facilitates the disassembly and replacement of welding heads, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A welding machine with an easy-to-disassemble and replace welding head includes a machine body. A connecting line is connected to the lower right end of the machine body. A handheld welding gun is fixedly connected to the end of the connecting line away from the machine body. An installation block is fixedly connected to the middle of the front end of the handheld welding gun. A connecting groove is opened at the front end of the installation block. An installation component is engaged inside the connecting groove. An embedding groove is opened at the front upper end and the front lower end of the installation block. An ejection groove is opened at the left end and the right end of the installation block. A moving mechanism is fixedly installed at each of the four corners of the lower end of the machine body. A control panel and operation buttons are provided at the front of the machine body.

[0006] Preferably, the mounting assembly includes a connecting block, a welding head body is fixedly mounted on the front end of the connecting block, an embedding block is fixedly connected to the front upper part and the front lower part of the connecting block, a compression groove is formed inside the connecting block and on the right inner part, a compression spring is fixedly connected to the inner wall of two adjacent compression grooves, a connecting piece is fixedly connected to the end of each of the two compression springs away from the inner wall of the compression groove, and a pop-out block is fixedly connected to the end of each of the two connecting pieces away from the compression spring.

[0007] Preferably, the connecting block engages with the connecting slot, and the two embedded blocks engage with the two embedded slots respectively.

[0008] By adopting the above technical solution—the snap-fit ​​between the connecting block and the connecting groove, and the synchronous embedding of the two embedded blocks and the embedded groove—dual positioning is achieved, which restricts the displacement of the welding head body from multiple dimensions.

[0009] Preferably, the two connecting pieces are located inside the two compression grooves, and the two connecting pieces are movably connected to the inner walls of the two compression grooves.

[0010] By adopting the above technical solution, the connecting piece can connect the pop-out block and the compression spring together. Preferably, the two pop-out blocks are slidably connected to the two compression slots respectively, and the two pop-out blocks are engaged with the two pop-out slots respectively.

[0011] By adopting the above technical solution, the pop-out block automatically pops out from the pop-out slot under the elastic force of the compression spring, forming a mechanical locking structure.

[0012] Preferably, the moving mechanism includes a mounting plate, a moving wheel is fixedly mounted on the lower end of the mounting plate, a fixed plate is fixedly connected to the right end of the mounting plate, a connecting plate is fixedly connected to the right end of the fixed plate, a cylinder is fixedly mounted on the upper end of the connecting plate, and a friction pad is fixedly mounted on the output end of the cylinder.

[0013] Preferably, the upper end of the mounting plate is fixedly connected to the bottom of the machine body, and the friction pad is located below the connecting plate.

[0014] By adopting the above technical solution, the friction pad can increase the friction between the friction pad and the ground, thereby enabling the machine body to be fixed in place at the place of use.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Insert the connecting block into the connecting groove, and simultaneously insert the two embedded blocks into the two embedded grooves. During this process, press the two pop-out blocks to move them into the two compression grooves and compress the compression springs. When the connecting block is fully engaged in the connecting groove, the pop-out blocks automatically pop out from their corresponding pop-out grooves under the spring force. The engagement of the connecting block with the connecting groove and the synchronous insertion of the two embedded blocks with the embedded grooves achieve dual positioning, limiting the displacement of the welding head body from multiple dimensions. At the same time, the pop-out blocks automatically pop out from their pop-out grooves under the spring force, forming a mechanical locking structure. This makes it easy and quick to install the welding head body on the handheld welding gun and also easy to quickly disassemble and replace it. The whole process is simple to operate and shortens the replacement time of the welding head body. It is especially suitable for welding operation scenarios with high work efficiency requirements, such as batch welding on a production line. 2. By setting a moving mechanism at the bottom of the machine body, when the machine body needs to be moved and adjusted, it can be adjusted by means of the moving wheels, without the need for additional handling tools, which improves the space adaptability and usage flexibility of the equipment. After adjusting to the working position, the cylinder is activated, and the cylinder pushes the friction pad to be pressed tightly against the working ground. The friction pad can increase the friction between the friction pad and the ground, thereby limiting and fixing the machine body in the use location, avoiding the equipment from being moved due to external interference, and ensuring the smooth progress of precision work such as welding.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please refer to Figures 1-4. This utility model provides a technical solution: A welding machine with an easy-to-disassemble and replace welding head includes a body 1. A connecting line 2 is connected to the lower right end of the body 1. A handheld welding gun 3 is fixedly connected to the end of the connecting line 2 away from the body 1. A mounting block 4 is fixedly connected to the middle of the front end of the handheld welding gun 3. A connecting groove 5 is opened at the front end of the mounting block 4. A mounting component 6 is engaged inside the connecting groove 5. An embedding groove 7 is opened at the front of the upper end and the front of the lower end of the mounting block 4. An ejection groove 8 is opened at the left end and the right end of the mounting block 4. A moving mechanism 9 is fixedly installed at the four corners of the lower end of the body 1. A control screen 10 and operation buttons 11 are provided at the front of the body 1.

[0022] In this embodiment, the installation component 6 includes a connecting block 61. A welding head body 62 is fixedly installed at the front end of the connecting block 61. An embedded block 63 is fixedly connected to both the upper front end and the lower front end of the connecting block 61. Compression grooves 64 are provided in the left and right inner parts of the connecting block 61. A compression spring 65 is fixedly connected to the inner wall of the two adjacent compression grooves 64. A connecting piece 66 is fixedly connected to the end of the two compression springs 65 away from the inner wall of the compression groove 64. A pop-out block 67 is fixedly connected to the end of the two connecting pieces 66 away from the compression spring 65. The connecting block 61 is engaged with the connecting groove 5. The two embedded blocks 63 are engaged with the two embedded grooves 7 respectively. The two connecting pieces 66 are located inside the two compression grooves 64 respectively, and the two connecting pieces 66 are movably connected to the inner wall of the two compression grooves 64 respectively. The two pop-out blocks 67 are slidably connected to the two compression grooves 64 respectively, and the two pop-out blocks 67 are engaged with the two pop-out grooves 8 respectively.

[0023] The above scheme involves inserting the connecting block 61 into the connecting groove 5, while simultaneously inserting the two embedding blocks 63 into the two embedding grooves 7. During this process, pressing the two pop-out blocks 67 causes them to move into the two compression grooves 64 and compress the compression spring 65. Once the connecting block 61 is fully engaged in the connecting groove 5, the pop-out blocks 67 automatically pop out from their corresponding pop-out grooves 8 under the spring force of the compression spring 65. The engagement of the connecting block 61 with the connecting groove 5 and the simultaneous embedding of the two embedding blocks 63 into the embedding grooves 7 achieve dual positioning, restricting the displacement of the welding head body 62 from multiple dimensions. At the same time, the pop-out blocks 67 automatically pop out from the pop-out grooves 8 under the spring force of the compression spring 65, forming a mechanical locking structure. This allows the welding head body 62 to be easily and quickly installed on the handheld welding gun 3, and also facilitates its rapid disassembly and replacement later.

[0024] In this embodiment, the moving mechanism 9 includes a mounting plate 91, a moving wheel 92 is fixedly mounted on the lower end of the mounting plate 91, a fixing plate 93 is fixedly connected to the right end of the mounting plate 91, a connecting plate 94 is fixedly connected to the right end of the fixing plate 93, a cylinder 95 is fixedly mounted on the upper end of the connecting plate 94, a friction pad 96 is fixedly mounted on the output end of the cylinder 95, the upper end of the mounting plate 91 is fixedly connected to the bottom of the body 1, and the friction pad 96 is located below the connecting plate 94.

[0025] With the above solution, when the machine body 1 needs to be moved and its position adjusted, it can be adjusted by means of the moving wheels 92 without the need for additional handling tools, which improves the spatial adaptability and usage flexibility of the equipment. After being adjusted to the working position, the cylinder 95 is activated, which pushes the friction pad 96 to be in close contact with the working ground. The friction pad 96 can increase the friction between the friction pad and the ground, thereby enabling the machine body 1 to be fixed in place at the usage location, avoiding the equipment from being moved due to external interference, and ensuring the smooth progress of precision work such as welding.

[0026] It should be noted that this utility model is a welding machine that facilitates the disassembly and replacement of welding heads. During use, the connecting block 61 is inserted into the connecting groove 5, and at the same time, the two inserting blocks 63 are also inserted into the two inserting grooves 7. During this engagement and insertion process, the two pop-out blocks 67 are pressed, causing them to move towards the corresponding compression grooves 64, and during this process, the compression spring 65 is compressed. When the connecting block 61 is fully engaged in the connecting groove 5, the pop-out blocks 67 will automatically reset under the elastic force of the compression spring 65 and pop out from the corresponding pop-out grooves 8. The engagement of the connecting block 61 with the connecting groove 5 and the two inserting blocks... The synchronous embedding of 63 and the embedding groove 7 achieves a dual positioning effect, restricting the displacement of the welding head body 62 from multiple dimensions. Moreover, the pop-out block 67 automatically pops out from the pop-out groove 8 under the elastic force of the compression spring 65, forming a mechanical locking structure. This allows the welding head body 62 to be easily and quickly installed on the handheld welding gun 3, and also facilitates its rapid disassembly and replacement. The entire installation and disassembly process is simple to operate, shortening the replacement time of the welding head body 62. It is especially suitable for welding operation scenarios with high work efficiency requirements, such as batch welding work on the production line. In addition, when it is necessary to move the machine body 1 to adjust its position, it can be done with the help of the moving wheels 92, without the need for additional handling tools, which improves the spatial adaptability and usage flexibility of the equipment. After the machine body 1 is adjusted to a suitable working position, the cylinder 95 is activated. The cylinder 95 pushes the friction pad 96 to fit tightly against the working ground. The friction pad 96 can increase the friction between the friction pad and the ground, thereby allowing the machine body 1 to be stably limited and fixed at the use location, preventing the equipment from shifting due to external interference, and ensuring that precision work such as welding can be carried out smoothly.
