Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a protective shell of an electric welding machine. Background Art

[0002] The core working principle of an electric welding machine is based on the high-temperature arc phenomenon that is excited when the positive and negative poles of the current are instantly short-circuited. This arc has extremely high thermal energy, which is enough to melt the solder on the welding rod and the base material to be welded, causing the two to achieve atomic-level bonding at the contact interface, thereby achieving a strong weld. From a structural point of view, an electric welding machine is essentially a highly specialized transformer that is designed to output high-power electrical energy sufficient to drive the welding process. The protective casing of the electric welding machine plays a vital role in the use of the electric welding machine. It not only protects the internal components from the influence of the external environment, but also ensures the safety of the operator during use.

[0003] When using common electric welding machines on the market, the welding wire is usually manually stretched to the position where welding is required. If the stretched welding wire is not properly fixed, the welding wire will hang on the ground. During the welding process, it may be accidentally pulled or tripped, resulting in line breakage or short circuit, causing a safety accident. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] See Figure 1 and Figure 2 As shown, a protective housing for an electric welding machine includes a housing 1, wherein the housing 1 includes a welding machine body 15, a top cover 5 is provided on the top of the housing 1, a connector 1 7 and a connector 2 16 are provided on the side of the welding machine body 15, a welding wire 9 is provided on the ends of the connector 1 7 and the connector 2 16 away from the welding machine body 15, a rotating shaft 11 is rotatably connected to the side of the housing 1 near the connector 2 16, a winder 10 is installed on the end of the rotating shaft 11 near the welding machine body 15, and the welding wire 9 is wound on the winder 10;

[0025] The rotating shaft 11 is connected to a pulley 17, and a pulley 2 19 is provided below the pulley 17. The pulley 17 and the pulley 2 19 are sleeved with the same belt 18. The pulley 2 19 is connected to a double-headed reciprocating screw 20 on the side away from the housing 1. A limit block is provided in the middle of the double-headed reciprocating screw 20. Two sliders 1 22 are threadedly connected on both sides of the limit block. A connecting rod 23, a slider 24, a positioning rod 21 and a connecting strip 25 are provided above the slider 1 22. The positioning rod 21 is located above the double-headed reciprocating screw 20, and the slider 24 is slidably connected to the positioning rod 21. The slider 24 is connected to the slider 1 22 through the connecting rod 23, and the slider 24 is connected to the collar 26 through the connecting strip 25 located above it.

[0026] In the specific implementation process, the shell 1 is made of strong and durable ABS material, which can effectively prevent the sparks generated during the welding process from damaging the internal components of the welding machine.

[0027] The winder 10 is provided with a guide groove of a size corresponding to the welding wire 9 for guiding the path of the welding wire 9 during the winding process, ensuring that the welding wire 9 can be neatly wound on the winder 10 to avoid crossing or knotting.

[0028] It should be noted that pulley 17 and pulley 2 19 are connected by belt 18 to form a transmission system. When the rotating shaft 11 rotates, pulley 17 rotates accordingly, and pulley 2 19 is driven to rotate by belt 18. The double-headed reciprocating screw 20 is connected to pulley 2 19. Its design makes the thread directions at both ends of the double-headed reciprocating screw 20 opposite. When the double-headed reciprocating screw 20 rotates, the two sliders 1 22 will move in opposite directions.

[0029] It should be noted that slider 1 22 is connected to slider 2 24 through connecting rod 23 to form a connecting rod mechanism. When slider 1 22 moves on the screw rod, slider 2 24 is driven to slide on the positioning rod 21 through connecting rod 23. As slider 2 24 moves, the ring 26 will also move accordingly. The ring 26 is mounted on the welding line 9 to realize automatic wire winding or adjust the position of the welding line.

[0030] See Figure 2 As shown, a protective shell of an electric welding machine, the two welding wires 9 connected to the connector 1 7 and the connector 2 16 are respectively located at the two ends of the winder 10 and connected to the rings 26 above the two sliders 1 22, and the positioning rod 21 is installed on the housing 1 at one end close to the pulley 2 19, and the other end is installed with a limit member 27.

[0031] It should be noted that the two welding wires 9 connected to connector 1 7 and connector 2 16 are located at both ends of the winder 10, so that the welding wires 9 can maintain balance during winding and releasing, avoiding uneven winding or entanglement problems caused by biasing to one side.

[0032] It should be noted that the main function of the limiter 27 is to limit the range of movement of the slider 24 on the positioning rod 21 to prevent it from excessive movement and damaging the mechanism or causing other adverse consequences. At the same time, the limiter 27 also plays a role in positioning and fixing, ensuring that the slider 24 can maintain a stable trajectory during movement.

[0033] See Figure 2 and Figure 4 As shown, a protective shell of an electric welding machine is provided. Anti-collision covers 6 are installed on three sides of the side of the electric welding machine body 15 away from the winder 10. The anti-collision covers 6 are installed inside the shell 1 by bolts and are made of polyurethane foam material.

[0034] During the specific implementation process, the polyurethane foam used in the anti-collision cover 6 is a lightweight, high-strength material with good shock absorption, cushioning and sound insulation properties. In the application of the electric welding machine, the anti-collision cover 6 made of polyurethane foam material can effectively resist external impacts while maintaining a lighter weight and will not have a negative impact on the overall performance of the electric welding machine. The anti-collision cover 6 is installed inside the shell 1 by bolts. This installation method is simple and reliable, and can ensure that the anti-collision cover 6 is firmly fixed on the electric welding machine body 15 to prevent it from loosening or falling off during operation. At the same time, the bolt connection also facilitates user maintenance and replacement.

[0035] See Figure 3 As shown, a protective shell of an electric welding machine is provided, wherein a hinge 8 is installed between a top cover 5 and a shell 1, a protrusion is installed on one side of the top cover 5 close to the winder 10, the top end of the protrusion is away from the shell 1, and the hinge 8 is installed on the opposite side of the protrusion.

[0036] During the specific implementation process, the protrusion serves as an auxiliary handle for opening the top cover 5. The user can easily open the top cover 5 by grabbing the protrusion, and the hinge 8 enables the top cover 5 to be opened and closed relative to the shell 1, making it convenient for the user to open the top cover 5 for internal maintenance or inspection.

[0037] See Figure 1 As shown, a protective shell of an electric welding machine is provided with support legs 2 at the four corners of the bottom of the shell 1, and a storage bin 3 is installed below the support legs 2. The storage bin 3 is made of stainless steel, and a self-locking universal wheel 4 is connected to the bottom of the storage bin 3.

[0038] During the specific implementation process, the self-locking universal wheel 4 is installed at the bottom of the storage bin 3, which provides convenient mobility for the welding machine. The user can easily move the welding machine at the work site by pushing it, which greatly improves work efficiency. At the same time, the self-locking function ensures that the welding machine can be firmly fixed in one position when needed, avoiding movement or sliding during work.

[0039] It should be noted that the design of the storage compartment 3 can provide an additional storage space for the welding machine, which is used to store accessories, tools or other related items of the welding machine.

[0040] See Figure 1 As shown, a protective shell of an electric welding machine is provided, wherein a connecting block 12 is provided on one end of a rotating shaft 11 away from the shell 1 , and a hand crank 13 is fixedly connected to the connecting block 12 .

[0041] During the specific implementation process, the connecting block 12 serves as a bridge between the rotating shaft 11 and the hand crank 13, and plays the role of transmitting rotational motion and torque. It allows the user to indirectly control the rotation of the rotating shaft 11 by operating the hand crank 13, thereby driving the winder 10 to wind the welding wire 9.

[0042] See Figure 1 As shown, a protective shell of an electric welding machine is provided. Dust-proof nets 14 are installed on three surfaces of the shell 1 where the anti-collision cover 6 is installed. The mesh surface of the dust-proof net 14 is made of galvanized wire material.

[0043] During the specific implementation process, the main function of the dustproof net 14 is to prevent dust and debris from entering the interior of the welding machine, protecting the electrical components and mechanical parts inside the machine from pollution and damage. At the same time, it can also improve the heat dissipation performance of the welding machine to a certain extent, reduce the operating temperature of the machine by allowing air circulation, and improve work efficiency and stability.

[0044] Working principle:

[0045] Step 1: The shell 1 is made of sturdy and durable ABS material. As the main protective barrier of the welding machine body 15, it can effectively prevent the sparks, high temperature and external impact generated during the welding process from damaging the internal components of the welding machine. The welding wire 9 is connected to the welding machine body 15 through the connector 1 7 and the connector 2 16, and is wound on the winder 10. The winder 10 is provided with a guide groove to ensure that the welding wire can be neatly wound. The winder 10 is installed on the rotating shaft 11. The winder 10 can be driven to reel and release the welding wire 9 by rotating the rotating shaft 11. The pulley 17 is connected to the pulley 2 19 by the belt 18 to form a transmission system. When the rotating shaft 11 rotates, the pulley 2 19 is driven to rotate by the pulley 17 and the belt 18. The double-headed reciprocating screw 20 is connected to the pulley 2 19, and the thread directions at both ends are opposite, so that the two sliders 1 22 can move in opposite directions.

[0046] Step 2: Slider 1 22 is connected to the double-headed reciprocating screw 20 through a thread, and moves with the rotation of the double-headed reciprocating screw 20. The connecting rod 23 connects slider 1 22 and slider 2 24 to form a connecting rod mechanism, so that slider 2 24 can slide on the positioning rod 21. The ring 26 is connected to slider 2 24 through the connecting strip 25, and is sleeved on the welding line 9. It moves with the movement of slider 2 24 to realize automatic winding or position adjustment of the welding line 9.

[0047] Step 3: The support legs 2 firmly support the welding machine to ensure its stability during use. The storage compartment 3 is installed under the support legs 2, providing additional storage space for the welding machine for storing accessories, tools and other items. The self-locking universal wheels 4 are installed at the bottom of the storage compartment 3, so that the welding machine can be easily moved at the work site. At the same time, the self-locking function ensures that the welding machine can be firmly fixed in one position when needed to avoid movement or sliding during work.
