[0002] An electric welding machine is a device that uses the high-temperature electric arc generated by the instantaneous short circuit of the positive and negative electrodes to melt the solder on the welding electrode and the material to be welded. Its structure is very simple, just a high-power transformer.

[0003] However, during the use process, if the worker finishes welding and the wire of the welding torch is cumbersome to gather up, it is often placed on the ground casually. Because the wire is relatively long, it may span the worker's walking path, so it is easy for the worker to kick the wire. On the one hand, it causes wear of the wire, and on the other hand, the welding torch at the end of the wire will also be worn against the ground. Summary of the Utility Model

[0004] In order to solve at least one technical problem mentioned in the background art, the purpose of the utility model is to provide an auxiliary welding device, which is convenient for storing the wire of the electric welding machine and reduces the friction damage of the wire with the ground.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Electric welding machines are widely used because of their small size, simple operation, convenient use, fast speed, and strong weld seams after welding. However, during use, if the worker finishes welding and the wire 5 of the welding torch 7 is cumbersome to gather up, it is often placed on the ground casually. Since the wire is long, it may span the worker's walking path, so the wire 5 is likely to be kicked by the worker. On the one hand, this causes wear on the wire 5, and on the other hand, the welding torch 7 at the end of the wire 5 will also be worn against the ground.

[0021] To solve the above technical problems. Please refer to Figures 1-4 , this embodiment provides an auxiliary welding device, including a welding box 1. A power supply is installed inside the welding box 1. A tray 2 is arranged on the lower side of the welding box 1. Two turntables 3 are rotatably installed on the tray 2. A reset member 4 is installed on the tray 2. The wire 5 is wound around the circumferential side of the turntable 3. A conductive slip ring 6 is installed in the middle of the turntable 3. The power supply is connected to the wire 5 through the conductive slip ring 6. The end of the wire 5 far from the turntable 3 is located outside the tray 2. A welding torch 7 is installed at the end of the wire 5 far from the turntable 3.

[0022] In the initial state, the wire 5 is wound around the turntable 3, and the welding torch 7 is located outside the welding box 1. When it is necessary to move the welding torch 7 on the welding box 1, take out the welding torch 7, and then pull out the wire 5 from the turntable 3. As the wire 5 is pulled out, the turntable 3 rotates accordingly, releasing the wire 5, so that the welding torch 7 gradually moves away from the welding box 1, facilitating the welding operation of the welding torch 7 on workpieces at a relatively long distance. After the workpiece is welded, the reset member 4 drives the turntable 3 to reverse, thereby winding up the wire 5 until the welding torch 7 approaches the welding box 1, thus completing the storage of the wire 5 and reducing the excessive length of the welding torch 7 and the wire 5, preventing the welding torch 7 and the wire 5 from being kicked by workers and over-worn against the ground.

[0023] Please refer to Figure 4 , where the reset member 4 includes a rotating shaft 41 fixedly installed on the tray 2. A jack 42 adapted to the rotating shaft 41 is provided in the middle of the circumferential side of the turntable 3. A receiving cavity 43 is provided on the circumferential side of the turntable 3 and outside the jack 42. A volute spring 44 is fixedly installed between the inner wall of the receiving cavity 43 and the side wall of the rotating shaft 41.

[0024] When the wire 5 is pulled out and the turntable 3 rotates, the turntable 3 rotates around the rotating shaft 41. At the same time, the volute spring 44 in the middle of the turntable 3 contracts, and elastic potential energy accumulates inside the volute spring 44, preparing for the reset of the turntable 3. When it is necessary to wind up the wire 5, under the elastic action of the volute spring 44, the turntable 3 rotates self, winding up the wire 5.

[0025] When the turntable 3 rotates, elastic potential energy accumulates inside the volute spring 44, and there is a tendency to drive the turntable 3 to reset. Therefore, a continuous pulling force needs to be applied to the wire 5 to prevent the turntable 3 from rotating back, which makes the welding process inconvenient. To solve the above problems.

[0026] Please refer to Figure 4 and Figure 5 As shown in FIGS. Figure 4 and Figure 5 , a plurality of ratchets 8 are fixedly installed on the lower side of the turntable 3. A top block 9 adapted to the ratchet 8 is slidably disposed on the tray 2. An elastic member 10 for driving the top block 9 to contact the ratchet 8 is installed on the tray 2. When the wire 5 is subjected to a tensile force, the ratchet 8 continuously pushes the top block 9 away from the ratchet 8. When the motor is not subjected to a tensile force, the ratchet 8 is engaged with the top block 9 to restrict the rotation of the turntable 3.

[0027] When the wire 5 is subjected to a tensile force, it will gradually be pulled away from the turntable 3 and drive the turntable 3 to rotate. The turntable 3 drives the ratchet 8 to rotate together. At this time, when the ratchet 8 contacts the top block 9, it will push the top block 9 to move away from the ratchet 8, thus not hindering the rotation of the turntable 3. When the wire 5 is not subjected to an external force, under the action of the scroll spring 44, the turntable 3 will reverse. At this time, the top block 9 will abut against the ratchet 8 and restrict the rotation of the turntable 3, thereby jamming the turntable 3 and preventing the wire 5 from being easily retracted.

[0028] Please refer to Figure 4 and Figure 5 As shown in FIGS. Figure 4 and Figure 5 , the elastic member 10 includes a housing 11 fixedly installed at the bottom of the tray 2. A cover plate 12 is disposed under the housing 11. The top block 9 is fixedly installed on the cover plate 12. A first spring 13 is fixedly installed between the cover plate 12 and the housing 11. By the movement of the cover plate 12 relative to the housing 11, the top block 9 is intermittently moved away from the ratchet 8, and the top block 9 is reset by the first spring 13 to abut against the ratchet 8.

[0029] To improve the moving stability of the top block 9, a guide rod 14 is fixedly installed on the cover plate 12, and a guide hole 15 for the guide rod 14 to pass through is formed in the housing 11. Through the mutual cooperation of the guide rod 14 and the guide hole 15, the cover plate 12 and the top block 9 move stably, reducing the deviation.

[0030] Please refer to Figure 1 As shown in FIG. Figure 1 , a support frame 16 is fixedly installed at the bottom of the welding box 1, and the support frame 16 is located at the four corners of the welding box 1. The bottom of the welding box 1 is supported by the support frame 16, facilitating the placement of the welding box 1.

[0031] Please refer to Figure 2 As shown in FIG. Figure 2 , a connecting rod 17 is fixedly installed on the two cover plates 12 located under the tray 2. Thus, when driving the cover plate 12 away from the housing 11, only by pulling the connecting rod 17 can the separation of the two cover plates 12 be completed simultaneously.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
