Description

Technical Field

[0001] The utility model relates to the field of repair welding guns, in particular to an adaptive repair welding gun. Background Art

[0002] Traditional welding methods are often limited by factors such as the environment, materials, and operator skills. In order to solve these problems, adaptive repair welding guns came into being. They can improve welding efficiency and quality, reduce human errors in the welding process by automatically adjusting welding parameters, and improve welding accuracy and consistency. Whether in high or low temperature environments, adaptive repair welding guns can automatically adjust parameters to ensure welding quality and stability.

[0003] The adaptive welding gun mainly monitors the temperature, current, voltage and other parameters during the welding process through the inclination sensor and control system, and makes real-time adjustments based on these data. The inclination sensor monitors the inclination angle of the welding gun and automatically changes the wire feeding speed of the welding wire. However, when using the welding gun for welding, since the welding gun will be in different positions, it will pull the connected hose, and the hose will be in a straight or relaxed state. At this time, it may require greater force to pull the welding gun, or affect the movement of the welding gun, thereby indirectly affecting the quality of welding. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the adaptive repair welding gun includes a welding box 1 with a control system inside. The welding box 1 is provided with a temperature sensor, a voltage detector and a current detector, etc., for detecting the temperature, voltage and current of the surrounding environment. A connecting hose 2 is installed on the surface of the welding box 1. A welding gun 3 is installed at the end of the connecting hose 2. The welding wire enters the interior of the welding gun 3 through the connecting hose 2. A tilt sensor 15 is installed on the surface of the welding gun 3. The tilt sensor 15 can detect whether the welding gun 3 is performing vertical welding or horizontal welding. A tension sensor 4 is installed on the surface of the welding box 1. One end of the tension sensor 4 is fixed to the surface of the welding box 1, and the other end of the tension sensor 4 is fixed to the surface of the connecting hose 2. A displacement component is installed on the surface of the welding box 1 for changing the position of the welding box 1.

[0021] When the staff is using it, the tilt angle of the welding gun 3 will be changed. At this time, the surface of the connecting hose 2 will be twisted, and the tension sensor 4 will produce a change in tension. The tension sensor 4 is set with a minimum value and a maximum value. When the detection value is not between the set values, the displacement component changes the position of the welding box 1, thereby changing the value of the tension so that it is between the set values, which makes it more convenient for the staff to operate the welding gun 3.

[0022] The displacement assembly includes a base 5, which is located directly below the welding box 1. The length and width of the base 5 are the same as those of the welding box 1. A fixing seat 6 is installed on the lower surface of the welding box 1, and the fixing seat 6 is installed inside the base 5. A threaded groove 7 is opened on the surface of the fixing seat 6, and the threaded groove 7 is set to penetrate. A motor 8 is installed inside the base 5, and a threaded rod 9 is fixedly installed on the end of the output shaft of the motor 8. The surface of the threaded rod 9 is threadedly connected to the inside of the threaded groove 7. A limiting assembly is installed on the surface of the welding box 1.

[0023] When in use, the motor 8 is started, driving the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the fixing seat 6, the limiting assembly can prevent the fixing seat 6 from rotating with the threaded rod 9. At this time, the fixing seat 6 can move along the axial direction of the threaded rod 9, thereby changing the tension of the connecting hose 2.

[0024] The limiting assembly includes a long slot 10, and the threaded rod 9 is movably installed inside the long slot 10. The two sides of the fixing seat 6 are against the two sides of the inner wall of the long slot 10. The long slot 10 limits the fixing seat 6 to ensure that the fixing seat 6 can only move inside the long slot 10.

[0025] A fixing plate 11 is fixedly installed on the surface of the welding box 1, and the fixing plate 11 is sleeved on the surface of the connecting hose 2. A connecting plate 12 is fixedly sleeved on the surface of the connecting hose 2. One end of the tension sensor 4 is fixed on the surface of the fixing plate 11, and a pull rope 13 is installed on the other end of the tension sensor 4. One end of the pull rope 13 is fixed on the surface of the connecting plate 12. When the connecting hose 2 bends, the pull rope 13 will move, and the pull rope 13 will pull the tension sensor 4, so that the value of the tension sensor 4 will change.

[0026] The number of the pull rope 13 and thus the tension sensor 4 is set to be multiple. In the present embodiment, the number of the tension sensors 4 is set to be four. The circular array is on the surface of the fixed plate 11. When the welding gun 3 is directed in different directions, the pull rope 13 can be pulled to move. When the value of one of the tension sensors 4 is not within the set range, the displacement component can be used to move the welding box 1, thereby ensuring higher accuracy of use.

[0027] A limit ring 14 is installed on the surface of the connecting hose 2 , and the limit ring 14 limits the path of the pull rope 13 to ensure that the pull rope 13 moves along the surface of the connecting hose 2 and ensures that the detection of the tensile force is more accurate. The pull rope 13 passes through the inside of the limit ring 14 .

[0028] It should be noted that the utility model is an adaptive repair welding gun. When in use, when the staff is using it, the tilt angle of the welding gun 3 will be changed. At this time, the surface of the connecting hose 2 will be twisted, thereby driving the pull rope 13 to move along the connecting hose 2, and the tension sensor 4 will produce a change in tension. The tension sensor 4 is set with a minimum value and a maximum value. When the detection value is not between the set areas, the displacement component changes the position of the welding box 1, thereby changing the value of the tension so that it is between the set values, which makes it more convenient for the staff to operate the welding gun 3.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
