DETAILED DESCRIPTION

[0018] Reference Figures 1 to 6 The present invention provides a technical solution: a welding anti-spatter device, comprising: A welding frame 1, on which a control box 2 and an emergency stop button 7 are fixedly arranged, and the emergency stop button 7 is electrically connected to the control box 2; A transverse regulator 3 is installed on the welding frame 1 and is used to drive the welding machine power supply box 4 transversely; the welding machine power supply box 4 is arranged on the transverse regulator 3 and is used to ensure normal power supply of the welding mechanism 5. The welding mechanism 5 is arranged on the welding machine power supply box 4 through bolt adjustment and is electrically connected to the welding machine power supply box 4; The fixing platform 6 is slidably arranged at the bottom of the welding frame 1 corresponding to the welding mechanism 5 .

[0019] The required welding workpiece is fixed by the fixing table 6, and the welding parameters of the welding machine power supply box 4 and the welding mechanism 5 are adjusted by the control box 2, as well as the moving speed of the lateral regulator 3. After completing the above operations, the welding machine power supply box 4, the welding mechanism 5 and the lateral regulator 3 are started by the control box 2 to perform welding operations on the workpiece.

[0020] During the welding operation on the workpiece, the welding mechanism 5 can detect the welding surface status of the workpiece in real time, so as to adjust the welding posture to prevent the sparks and impurities generated during welding from splashing around, and to prevent the impurities from adhering to the workpiece and welding equipment after cooling, causing inconvenience in subsequent cleaning.

[0021] As a preferred embodiment, the welding mechanism 5 includes: an electric telescopic rod 51, a welding gun 52, a mounting plate 54, a protective cover 55, and two adjustment components 8; One end of the electric telescopic rod 51 is set on the welding machine power supply box 4 by bolt adjustment, and the other end is fixedly provided with the mounting plate 54, and the welding gun 52 is fixedly provided on the mounting plate 54, and the power supply input end of the welding gun 52 is electrically connected to the welding machine power supply box 4; The protective cover 55 is coaxially sleeved on the welding gun 52; The two adjustment components 8 are symmetrically arranged on the mounting plate 54 with the welding gun 52 as a symmetry axis, and are movably connected to the protective cover 55 .

[0022] As a preferred embodiment, an elastic rubber ring is provided at the contact portion between the protective cover 55 and the welding gun 52 . During the process of adjusting the protective cover 55 by the adjusting assembly 8 , the elastic rubber ring can provide a certain amount of movement margin to avoid interference between the protective cover 55 and the welding gun 52 .

[0023] It should be noted that the relative angle between the electric telescopic rod 51 and the welding machine power supply box 4 can be adjusted by bolts according to the welding angle of the welding workpiece, that is, the relative angle between the welding gun 52 and the welding workpiece can be adjusted, so as to make it easier to weld special workpieces and improve the welding quality.

[0024] During the welding process, the electric telescopic rod 51 can sense the contact pressure between the welding gun 52 and the welding workpiece, thereby maintaining the stability of the welding pressure between the welding gun and the welding workpiece and improving the overall quality of welding. At the same time, during the welding process, the adjustment component 8 always keeps in contact with the surface of the welding workpiece, so that the adjustment component 8 can sense the surface state of the welding workpiece, so that the protective cover 55, under the action of the adjustment component 8, always maintains a relatively parallel state with the current welding point of the welding workpiece, that is, the welding point can always be wrapped to the maximum extent, preventing welding sparks from flying around, that is, while ensuring the welding quality, avoid impurities splashing and polluting the environment and air.

[0025] As a preferred embodiment, the adjustment assembly 8 includes: a support arm 81, one end of the support arm 81 is rotatably disposed on the mounting plate 54, and the other end is rotatably connected to a linkage slide rod 82, a slide cylinder 86 is slidably disposed on the linkage slide rod 82, and an adjustment guide wheel 85 is rotatably disposed on the slide cylinder 86; The limiting slide post 83 is fixedly arranged on the mounting plate 54, and a slide rod is slidably arranged on the axis of the limiting slide post 83, and the slide rod is connected to the slide cylinder 86; The linkage assembly 9 is disposed on the mounting plate 54 and is connected to the slide bar and the protective cover 55 at the same time.

[0026] As a preferred embodiment, a torsion spring is provided at the connection shaft between the slide cylinder 86 and the adjusting guide wheel 85. The torsion spring can maintain the stability of the movement of the adjusting guide wheel 85 and reduce the vibration generated during the rolling process.

[0027] As a preferred embodiment, a compression spring 84 is provided between the slide cylinder 86 and the mounting plate 54 via the limiting slide post 83 .

[0028] It should be explained that when the welding parameters are adjusted and welding begins, the electric telescopic rod 51 first drives the welding gun 52 to contact the surface of the welding workpiece. In the process of the electric telescopic rod 51 driving the welding gun 52 to contact the workpiece, the adjustment guide wheel 85 will first contact the surface of the workpiece. At this time, the adjustment guide wheel 85 causes the slide bar to slide through the slide cylinder 86 during the squeezing process with the workpiece, and at the same time squeezes the compression spring 84, and drives the linkage assembly 9 during the upward sliding process of the slide bar, so that the protective cover 55 slowly rises. When the welding gun 52 contacts the welding point of the workpiece and reaches the optimal welding pressure, the height of the protective cover 55 is just enough to expose the welding head of the welding gun 52, and the height of the protective cover 55 can just wrap the spark impurities generated by welding in the best way, preventing the spark impurities generated during the welding process from splashing around.

[0029] When an inclined welding state is encountered during the welding process, a relative height difference is generated between the adjusting guide wheels 85 on both sides, that is, the adjusting guide wheels 85 on both sides are inclined parallel to the inclined surface of the workpiece. At this time, the state of the adjusting guide wheel 85 is transmitted to the linkage component 9 through the slide rod, and the linkage component 9 synchronously adjusts the state of the protective cover 55, so that the inclination angle of the protective cover 55 is the same as the inclination angle of the workpiece welding, that is, the protective cover 55 is maintained in the welding state and can always remain parallel to the welding surface of the workpiece, avoiding the phenomenon of incomplete local shielding due to the inclination of the protective cover 55, resulting in the splashing of sparks and impurities.

[0030] The support arm 81 and the linkage slide rod 82 limit the movement of the adjusting guide wheel 85 during the welding process, thereby improving the stability of its movement.

[0031] It should be noted that when the welding gun 52 is in the retracted state, the protective cover 55 falls down to wrap around the welding head of the welding gun 52 to improve the protection of the welding gun 52.

[0032] As a preferred embodiment, the linkage assembly 9 includes: a first gear 92, which is rotatably disposed on the mounting plate 54 and meshes with a first rack 91, and the first rack 91 is connected to the slide rod; A second gear 93, coaxially fixed on the first gear 92; The second rack 94 is slidably disposed on the mounting plate 54 and meshes with the second gear 93 ; the second rack 94 is movably connected to the protective cover 55 via a connecting member 95 .

[0033] As a preferred embodiment, the connecting member 95 includes: a connecting seat 951, two adjusting springs 952; The connecting seat 951 is slidably disposed on the protective cover 55 ; the two adjusting springs 952 are symmetrically arranged with the connecting seat 951 , one end of which is fixed on the protective cover 55 , and the other end of which is abutted against the connecting seat 951 .

[0034] It should be noted that the sliding rod causes the first rack 91 to drive the first gear 92 to rotate, and the rotation of the first gear 92 causes the second gear 93 to rotate, thereby causing the second rack 94 to slide.

[0035] During the sliding process of the second rack 94, the connecting seat 951 is pulled to adjust the two sides of the protective cover 55 so that it always remains relatively parallel to the workpiece surface. The adjusting spring 952 can adjust the position of the connecting seat 951 when the pulling torque of the second rack 94 changes to cooperate with the movement of the second rack 94.

[0036] During specific implementation, the workpiece is fixed on the fixed table 6, and the welding parameters are adjusted using the control box. After the parameter adjustment is completed, the welding mechanism 5 is started. During the welding process, the welding mechanism 5 senses the surface state of the welding workpiece through the adjustment component 8, so that the protective cover 55 can be adjusted according to the inclination state of the workpiece surface, so that it always remains relatively parallel to the workpiece surface, reducing the pollution caused by the splashing of sparks and impurities generated by welding, and improving the cleanliness of the equipment.

[0037] What has been described above are only preferred specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, which should be covered by the protection scope of the present invention.
