Description

Technical Field

[0001] This application relates to the technical field of welding machines, and in particular to a welding machine material shortage induction device. Background Technique

[0002] A welding machine is an electrical device that uses the high-temperature electric arc generated by the momentary short circuit between the positive and negative electrodes to melt the solder on the welding electrode and the material to be welded, thereby achieving the purpose of welding. Its main structure includes an input power supply, a transformer, and a rectifier. The transformer is used to adjust the input voltage to a voltage suitable for welding, and the rectifier is responsible for converting alternating current into direct current and supplying it to the welding circuit.

[0003] Compared with the existing welding machines in the actual use process, one of them uses a reel of welding wire during use, and the welding wire on the reel is continuously extracted by manual feeding. However, since the welding wire reel is inside the device and cannot be viewed at any time, it makes the operator unable to know in time after the welding wire on the reel is used up, which will affect the continuity of welding.

[0004] Therefore, to solve the above problems, this application provides a welding machine material shortage induction device.

[0005] The above information disclosed in this background technique is only used to increase the understanding of the background technique of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Utility Model Content

[0006] In order to solve the problem of not being able to know that the welding wire is about to run out, this application provides a welding machine material shortage induction device.

[0007] A welding machine material shortage induction device provided by this application includes a welding box. One end inside the welding box is welded with a sleeve rod, a wire reel is sleeved outside the sleeve rod, a limit bolt is rotatably connected to the outside of one end of the sleeve rod, isolation springs are installed on both sides of the wire reel by the limit bolt and one end of the sleeve rod, and a welding wire is wound outside the wire reel;

[0008] Two fitting cylinders are welded to the bottom end inside the welding box. Guide rods are slidably inserted into both of the fitting cylinders. A welding wire limiting rod is welded to the tops of the two guide rods. A connecting rod is welded to the bottom end of the welding wire limiting rod between the two guide rods. A reset spring is installed in the middle of the bottom end of the connecting rod. A warning lamp is installed outside one end of the welding box.

[0009] Preferably, the bottom ends inside the two fitting cylinders are respectively connected to the positive and negative poles of the warning lamp through wires, and one end of the welding wire limiting rod is connected to the external power output end.

[0010] Preferably, the bottom end of the reset spring is connected to the bottom end inside the welding box.

[0011] Preferably, two rotating shafts are rotatably connected to one end inside the electric welding box, wire feeding discs are welded to the outer sides of the two rotating shafts, driving gears are welded to the outer sides of the two rotating shafts on one side of the wire feeding discs, and the two driving gears are meshed with each other.

[0012] Preferably, a guiding pipe is welded to the outer side of one end of the electric welding box, a baffle is fixed to one side of the electric welding box by bolts, a rotating disc is rotatably connected to the surface of the baffle, and one end of the rotating disc penetrates through the baffle and is connected to one end of a rotating shaft.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. Due to the characteristic that the height of the welding wire passing through the two wire feeding discs on the outer side of the wire reel is higher than that of the welding wire limiting rod, the welding wire is passed through the bottom of the welding wire limiting rod, thereby lifting the welding wire limiting rod, so that the two guide rods welded to the bottom end of the welding wire limiting rod are disconnected from the two fitting cylinders. After the welding wire is used up, the welding wire limiting rod without support will make the guide rod and the fitting cylinder connected again to light up the warning light to achieve the warning effect. Compared with the prior art, it has the effect of prompting and can enable the operator to timely know that the welding wire has been used up. Description of the Drawings

Specific Embodiments

[0020] The following will further describe the present application in detail Figures 1 - 4 with reference to the attached

[0021] Embodiment 1

[0022] Refer to Figures 1 - 4, A material shortage induction device for an electric welding machine, comprising an electric welding box 1. One end inside the electric welding box 1 is welded with a sleeve rod 2. A wire reel 3 is sleeved outside the sleeve rod 2. One end outside the sleeve rod 2 is rotatably connected with a limit bolt 4. Isolation springs 5 are installed on both sides of the wire reel 3 between the limit bolt 4 and one end of the sleeve rod 2. To prevent excessive clamping and make the wire reel 3 unable to rotate, a welding wire 6 is wound outside the wire reel 3. Two fitting cylinders 7 are welded to the bottom end inside the electric welding box 1. Guide rods 8 are slidably inserted into the two fitting cylinders 7. A welding wire limiting rod 9 is welded to the tops of the two guide rods 8. A connecting rod 10 is welded to the bottom end of the welding wire limiting rod 9 between the two guide rods 8. A reset spring 11 is installed in the middle of the bottom end of the connecting rod 10. To implement the reset function for the conductive mechanism, the bottom end of the reset spring 11 is connected to the bottom end inside the electric welding box 1. A warning light 16 is installed on the outside of one end of the electric welding box 1. To warn the operator that the welding wire 6 is used up, the bottom ends of the two fitting cylinders 7 are respectively connected to the positive and negative electrodes of the warning light 16 through wires. One end of the welding wire limiting rod 9 is connected to the external power output end. Two rotating shafts 12 are rotatably connected to one end inside the electric welding box 1. Feeding disks 13 are welded to the outside of the two rotating shafts 12. Transmission gears 14 are welded to the outside of the two rotating shafts 12 on one side of the feeding disks 13, and the two transmission gears 14 mesh with each other. To drive the welding wire 6, a guiding tube 15 is welded to the outside of one end of the electric welding box 1. A baffle 18 is fixed to one side of the electric welding box 1 by bolts. A turntable 17 is rotatably connected to the surface of the baffle 18. One end of the turntable 17 penetrates through the baffle 18 and is connected to one end of a rotating shaft 12.

[0023] Working principle: First, the operator opens the baffle 18 fixed to one side of the electric welding box 1 by bolts. Then, the limit bolt 4 rotatably connected to one end of the sleeve rod 2 welded to one end inside the electric welding box 1 is unscrewed. Then, the empty wire reel 3 sleeved outside the sleeve rod 2 is removed. Then, a new wire reel 3 is sleeved outside the sleeve rod 2. Then, the limit bolt 4 is tightened. During this period, ensure that the welding wire 6 wound outside the wire reel 3 comes out from the bottom of the wire reel 3. Then, pass the welding wire 6 through the bottom end of the welding wire limiting rod 9, and then through the clamping ends of the two feeding disks 13. Then, insert the welding wire 6 into the guiding tube 15 welded to the outside of one end of the electric welding box 1. Connect the guiding tube 15 to the inlet end of the welding torch;

[0024] Subsequently, the operator rotates the turntable 17. At this time, the turntable 17 will drive a rotating shaft 12 connected thereto to rotate, and the rotating shaft 12 will drive a transmission gear 14 welded to its outer side to rotate, and the transmission gear 14 will drive another transmission gear 14 meshed with it to rotate, and the transmission gear 14 will drive another wire feeding disc 13 welded to it to rotate. At this time, the two clamped wire feeding discs 13 will convey the welding wire 6 clamped between them outward. During this period, the welding wire 6 will be continuously pulled out from the outer side of the wire reel 3. At the same time, the welding wire 6 at the bottom end of the welding wire limiting rod 9 will lift the welding wire limiting rod 9, and the welding wire limiting rod 9 will drive the two guide rods 8 welded to its bottom end to lift together. At this time, the two guide rods 8 will slide from the inner bottom end of the two fitting cylinders 7 to the inner top of the fitting cylinder 7, and at the same time, the fitting cylinder 7 and the guide rod 8 will be disconnected from each other;

[0025] And as the welding wire 6 continues to go out, the welding wire 6 will enter the welding end of the welding torch through the incoming wire end of the welding torch. At this time, stop rotating the turntable 17. After the extended welding wire 6 is used up, rotate the turntable 17 again. As the welding wire 6 is continuously used, after the welding wire 6 on the outer side of the wire reel 3 is used up, the welding wire limiting rod 9 will fall due to the loss of the lifting of the welding wire 6. At the same time, the connecting rod 10 welded between the two guide rods 8 will also be pulled downward by the return spring 11, and at the same time, drive the two guide rods 8 to move downward together. At this time, the two guide rods 8 will be fitted again to the inner bottom end of the two fitting cylinders 7. Since the inner bottom ends of the two fitting cylinders 7 are respectively connected to the positive and negative electrodes of the warning lamp 16 through wires, and one end of the welding wire limiting rod 9 is connected to the external power output end, so after the two guide rods 8 are fitted again to the inner bottom end of the two fitting cylinders 7, the warning lamp 16 will light up, which will provide a warning to the user. Such a design can enable the operator to know in time after the welding wire 6 is used up, so as not to interrupt the continuity of welding.

[0026] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
