Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figure 1-3 This embodiment relates to a structure of an anti-spatter welding gun head 101 for an electric welding machine, including a protective component 1 installed on the gun head 101 located on the welding gun body 100. The protective component 1 includes a base 11 provided on the gun head 101, a transparent plate 12 installed on the base 11, and a protective cover 13 installed on the transparent plate 12 around the gun head 101.

[0021] Specifically in this embodiment, such as Figure 1 The welding gun body 100 and its protective components 1 and 2 are shown in the overall structural configuration. Figure 1 Taking a welding gun body 100, which adopts one of the common welding gun structures in existing technology, as an example, the base 11 is designed to be connected and fixed to the gun head 101. The transparent plate 12 can be fitted and fixed to the base 11 through a through groove 121 in its middle. The size of the transparent plate 12 can be set according to the length of the gun head 101, without affecting normal welding operations and facilitating the determination of the welding position of the gun head 101. At the same time, the transparent plate 12 can be made of a fully transparent (for easy observation) or semi-transparent (which can be set in conjunction with the observation window structure on the welding protective mask, facilitating observation while providing a certain degree of anti-flash and eye protection) material with certain fireproof and high-temperature resistance properties, and can be composed of a single layer or multiple layers, depending on the characteristics of the welding operation and usage requirements. Figure 2 or Figure 3As shown, the protective cover 13, which is installed on the transparent plate 12 around the gun head 101, is shaped like a pot lid or a horn with an opening in the middle, as shown in the figure. The protective cover 13 can be made of the same material as the transparent plate 12 and can form an integral structure with the transparent plate 12, or it can be made of a composite material with fireproof and high temperature resistance with the base 11 to ensure the structural stability of the protective component 1 during the welding process. At the same time, the height of the protective cover 13 is set so that its bottom edge does not exceed the flame nozzle at the bottom of the gun head 101, so that it does not affect the operator's adjustment of the corresponding welding angle. This structure adds a protective component 1 to the gun head 101 of the welding gun body 100. The transparent plate 12 allows the operator to easily observe the welding position and adjust the welding angle of the gun head 101 while operating the welding gun body 100. Combined with the structure of the protective cover 13, the spatter of welding slag and other welding materials is effectively reduced during welding, thus reducing the area and probability of damage to the surface of the welded product. The spatter can also accumulate at the welding position, facilitating subsequent cleaning and minimizing unnecessary harm to the operator's eyes and skin. This improves the operator's ease of operation and safety during welding, reducing operational risks and safety hazards. In addition, the overall structure of the protective component 1 is simple and can be flexibly adjusted according to the characteristics of the welding operation and usage requirements, ensuring structural stability, flexibility, and applicability during the welding process.

[0022] The transparent plate 12 is detachably connected to the base 11 via a locking member 111 rotatably mounted on the base 11, and the protective cover 13 is detachably connected to the transparent plate 12 via a ring plate 14 surrounding the transparent plate 12. Figure 2 As can be seen, the locking member 111 is detachably connected to the base 11 via a threaded structure, thereby realizing the detachable connection between the transparent plate 12 and its protective cover 13 on the base 11. Simultaneously, combined with... Figure 3 As shown, the two sides of the ring plate 14 are respectively provided with ring grooves 141 for connecting the transparent plate 12 and the protective cover 13. The size of the ring grooves 141 is adapted to the thickness of the transparent plate 12. The protective cover 13 is fixed on the ring plate 14 by having an inner edge 130 with a size adapted to the ring grooves 141 at the top. This realizes the detachable connection process of the protective cover 13 to the transparent plate 12 through the ring plate 14, further improving the detachability and disassembly flexibility of the protective component 1, facilitating daily inspection and cleaning as well as subsequent replacement operations, and improving the speed and flexibility of operation during use.

[0023] The transparent plate 12 and the base 11 are connected by a spline structure, and the ring plate 14 and the protective cover 13 are rotatably mounted around the transparent plate 12 via a rotating handle 142 installed on the ring plate 14. The ring plate 14, corresponding to the mounting position of the rotating handle 142, is provided with scrapers that rotate and adhere to the upper and lower side walls of the transparent plate 12. Figure 1-3 As can be seen, the diameter of the corresponding annular groove 141 connecting the annular plate 14 and the transparent plate 12 can be slightly larger than the diameter of the transparent plate 12 to allow for clearance fit. The corresponding annular groove 141 connecting to the protective cover 13 can be interference-fitted with the inner edge 130 of the top of the protective cover 13 to improve the rotational stability and ease of operation of the annular plate 14 and the protective cover 13 on the transparent plate 12. Simultaneously, the spline structure includes multiple sets of spaced pin plates 112 arranged around the side wall of the base 11 and multiple sets of spaced pin grooves arranged around the inner wall of the through groove 121 of the transparent plate 12 for sliding engagement of the pin plates 112. 122, to achieve a stable connection and position limitation of the transparent plate 12 on the base 11, so that the rotating handle 142 installed on the ring plate 14 can realize the cyclic rotation of the ring plate 14 and the protective cover 13 on the transparent plate 12. At the same time, during the rotation of the ring plate 14, the scraper that is in contact with the upper and lower side walls of the transparent plate 12 can scrape off the welding slag and other spatters attached to the transparent plate 12 in a timely manner, thereby reducing the unnecessary impact on the observation field caused by the welding slag and other spatters attached to the transparent plate 12 during the welding process, and further improving the functional diversity and operational stability of the protective component 1.

[0024] The ring plate 14 includes two sets of arc-shaped plates 140 that are detachably mounted on the transparent plate 12 via a plug-in structure. The handle 142 and the scraper are mounted and set on one set of arc-shaped plates 140. Specifically, from Figure 2 As can be seen, the plug-in structure includes plug plates provided on both ends of a set of arc-shaped plates 140 and slots 144 provided on both ends of another set of arc-shaped plates 140 for plug-in insertion. This enables the detachable connection of the ring plate 14 formed by plugging in the two sets of arc-shaped plates 140, thereby further improving the structural detachability of the ring plate 14 and the ease of detachable connection to the transparent plate 12 and the protective cover 13, further improving the structural detachability and disassembly flexibility of the protective component 1, facilitating the disassembly, cleaning, and replacement of the corresponding structure, and meeting different usage requirements.

[0025] The protective cover 13 includes a first cover 131 detachably connected to the ring plate 14 and a second cover 132 formed by multiple sets of arc plates 1321 arranged at intervals around the first cover 131 and each set of brushes 1322. The second cover 132 is detachably mounted on the first cover 131 by means of an outer edge 1311 at the bottom of the first cover 131 for mounting the arc plates 1321, multiple sets of spaced grooves 1320 respectively opened on the arc plates 1321, and multiple sets of slots 1312 opened on the outer edge 1311 corresponding to the grooves 1320. The second cover 132 is detachably mounted on the first cover 131 by a serpentine guide wire 133 that is made of high temperature resistant material and whose two ends can be connected by wrapping or welding. Figure 2 or Figure 3 In the case of the exception, the baffle wire 133 on the outer edge 1311 is wound around the groove 1320 and the slot 1312 respectively, so that the second cover 132 formed by multiple sets of arc plates 1321 is stably connected to the outer edge 1311 of the first cover 131. The protective cover 13 with this structure can have a certain deformation effect through the several brushes 1322 set on the multiple sets of arc plates 1321 in the second cover 132. When the welding angle is adjusted during the welding process, it can contact the surface of the weldment and produce appropriate deformation, thereby The addition of the protective cover 13 further reduces the impact on the welding angle adjustment. The addition of the brush 1322 also facilitates the cleaning of welding slag and other spatter attached to the corresponding area on its surface. The second cover 132 can be selectively added according to the usage requirements. At the same time, in order to reduce the impact of welding temperature on the brush 1322, the brush 1322 can be set as a steel brush according to the material of the welding product, further improving the cleaning effect of welding slag and other residues on the welding position and meeting different usage requirements.

[0026] The length of the outer edge 1311 at the bottom of the first cover 131 is greater than the width of the arc plate 1321. This arrangement allows the connection point between the upper end of the brush 1322 and the arc plate 1321 to be located above the outer edge 1311 of the first cover 131, giving the brush 1322 a redundant length above the outer edge 1311. This provides a certain blocking effect for the brush 1322 on the arc plate 1321 at the outer edge 1311 of the first cover 131, reducing the deformation of the brush 1322 in the direction from the outer edge 1311 towards the inner edge 130 near the gun head 101. The probability and degree of bending are reduced, and the unnecessary impact of the addition of brush 1322 on the welding operation is reduced. In addition, after the brush 1322 on the multiple sets of arc plates 1321 is installed on the outer edge 1311 of the first cover body 131, the lower end of brush 1322 can be bent at a certain arc along the corresponding length extended below the outer edge 1311 in a direction away from the gun head 101. This does not affect the stability of the function of brush 1322, but can also effectively reduce the unnecessary wear or even damage to the surface of the welded part caused by the bottom tip of brush 1322, thereby improving the flexibility and applicability of use.

[0027] A second protective component 2 is also installed on the handle 102 of the welding gun body 100. The second protective component 2 includes a retaining plate 21 detachably mounted on the handle 102 and an arc-shaped baffle 22 rotatably disposed below the handle 102. The retaining plate 21 and the arc-shaped baffle 22 are detachably connected via a pin 23 passing through them and a locking piece 231 at one end of the pin 23. Specifically... Figure 1 and Figure 4 As can be seen, the structure of the clamping plate 21 allows for detachable connection to the handle 102 of the welding gun body 100 via the adapter ring 211 provided thereon. The arc-shaped baffle 22 connected to the clamping plate 21 can be positioned below the handle 102 and provides a certain degree of protection for the operator's hands, further reducing the probability of unnecessary injury to the operator's hands caused by welding slag and other spatter during the welding process. At the same time, the pin 23 can pass through the through holes 20 opened at corresponding positions on the clamping plate 21 and the arc-shaped baffle 22 respectively. Combined with the locking member 231 with a bolt connection or a snap spring structure, the position of the pin 23 is limited, which facilitates the disassembly and assembly of the clamping plate 21 and the arc-shaped baffle 22. At the same time, the arc-shaped baffle 22 located below the handle 102 can be rotated and adjusted at a certain angle on the clamping plate 21, further improving the structural detachability and usage flexibility of the second protective component 2. Combined with the protective component 1, it can further improve the safety of the operator operating the welding gun body 100 for welding operations and the protection effect on the operator.
