[0002] When the laboratory conducts flat-plate butt welding process assessment, spatter is inevitable. It is often necessary to grind and clean the welding spatter after welding, which will undoubtedly increase the workload. Moreover, since the use of angle grinders for grinding will generate noise, dust and vibration, it will cause great harm to the health of the grinding operators. In addition, during the grinding process, workers are required to apply pressure to the angle grinder for grinding, which has high labor intensity and there is a safety hazard of grinding disc breakage and injury.

[0003] The anti-splash means in the prior art can usually use a baffle to shield the welding spatter to protect the welding test plate. However, when the baffle is connected to the welding gun, the technician cannot freely adjust the baffle spacing according to the gap between the welding plates. If the baffle spacing is larger than the welding plate spacing, it is easy to cause the baffle at the edge of the weld to still be affected by the welding spatter, thereby affecting the welding plate.

[0004] In view of this, it is necessary to propose a weld seam welding spatter prevention device to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0005] The main purpose of the utility model is to provide a weld seam anti-splash device to solve the problem that the welding means in the prior art cannot freely adjust the baffle spacing, so that the baffles at the weld edge are still susceptible to welding spatter.

[0009] The top of the connecting block is recessed inward to form a trapezoidal groove matched with the trapezoidal fixing block. The trapezoidal groove is set to penetrate in the transverse direction. The trapezoidal fixing block is set in the trapezoidal groove of the connecting block so that the baffle can be slidably adjusted in the transverse direction.

[0010] Preferably, a threaded hole extending in the vertical direction is formed on the trapezoidal fixing block, and the trapezoidal fixing block is supported on the connecting block by a fixing bolt passing through the threaded hole, so as to be fixedly connected with the connecting block.

[0011] Preferably, the baffle is L-shaped, and comprises a bottom baffle and a side baffle, the connecting block is fixed on the bottom baffle, and the side baffle is erected on a side of the bottom baffle away from the nozzle.

[0031] Please see attached Figure 1-2 In one embodiment of the utility model, a weld 410 welding anti-splash device is provided, comprising a welding gun 30, a fixing ring 20 and two shielding mechanisms 10 relatively arranged on both sides of the fixing ring 20. First of all, it should be noted that the longitudinal direction in the present application refers to the direction in which the welding gun 30 moves during welding, that is, the extension direction of the weld 410 between the two welding plates 40, and the transverse direction refers to the horizontal direction perpendicular to the longitudinal direction, that is, the direction in which the two welding plates 40 are relatively arranged; and different from the anti-splash means in the prior art, a baffle can usually be used to shield the welding spatter to protect the welding test plate, but when the baffle is connected to the welding gun, the technician cannot freely adjust the baffle spacing according to the gap between the welding plates. If the baffle spacing is greater than the welding plate spacing, it is easy to cause the baffle at the edge of the weld to still be affected by the welding spatter, thereby affecting the welding plate. The details are as follows:

[0032] The welding gun 30 includes a welding gun body 310 and a nozzle 320. The welding gun body 310 is arranged in the fixing ring 20. The nozzle 320 is sleeved on the welding gun body 310 and arranged between the two shielding mechanisms 10. The top of the nozzle 320 can be abutted against the fixing ring 20. Each of the shielding mechanisms 10 includes a connecting strip 110 and a baffle 120 extending in the longitudinal direction. The top of the connecting strip 110 is fixedly connected to the fixing ring 20. The connecting strip 110 is fixedly connected to the fixing ring 20. The bottom end of 110 is protruded outward to form a trapezoidal fixing block 111 extending in the transverse direction, and the baffle 120 is protruded upward to form a connecting block 121, wherein the top of the connecting block 121 is recessed inward to form a trapezoidal groove 122 matched with the trapezoidal fixing block 111, and the trapezoidal groove 122 is set to pass through in the transverse direction, and the trapezoidal fixing block 111 is set in the trapezoidal groove 122 of the connecting block 121, so that the baffle 120 can be slidably adjusted in the transverse direction.

[0033] Specifically, the welding anti-splash device of the weld 410 in the present application includes a welding gun 30, a fixing ring 20 and two shielding mechanisms 10. The welding gun 30 is a welding tool, and the fixing ring 20 is used for installing the welding gun 30. The welding gun 30 is connected to the fixing ring 20 by being sleeved on the welding gun 30, and the shielding mechanism 10 is used to prevent the spatter generated during welding from affecting the welding plates 40 on both sides. Therefore, the two shielding mechanisms 10 are arranged on both sides of the fixing ring 20 in a horizontal direction, so that the welding gun 30 and the shielding mechanism 10 arranged in the fixing ring 20 are integrated into one. When welding, the shielding mechanism 10 can move with the welding gun 30.

[0034] Among them, the welding gun 30 includes a welding gun body 310 and a nozzle 320. The welding gun body 310 is the rod part of the welding gun 30 body, and the nozzle 320 serves as the nozzle of the welding gun 30. In the embodiment of the present application, it is arranged on the welding gun body 310 in the form of a sleeve. It is worth noting that since the fixing ring 20 is usually matched with the size of the welding gun body 310, the size of the nozzle 320 sleeved on the welding gun body 310 will be larger than the size of the welding gun body 310. At this time, after the welding gun body 310 passes through the fixing ring 20, the nozzle 320 is sleeved under the fixing ring 20 (that is, between the two shielding mechanisms 10), the top of the nozzle 320 can be against the fixing ring 20, so that the welding gun 30 and the fixing ring 20 are firmly connected.

[0035] Furthermore, each of the shielding mechanisms 10 includes a connecting strip 110 and a baffle 120 extending in the longitudinal direction, wherein the connecting strip 110 is used to connect the baffle 120 to the fixing ring 20, and to extend the baffle 120 to the bottom so as to be laid on the welding plate 40, and the baffle 120 is arranged in the longitudinal direction so as to be consistent with the extension direction of the weld 410 between the welding plates 40, thereby ensuring that the protective effect can be maintained in real time during the welding movement; the bottom end of the connecting strip 110 is convexly formed with a trapezoidal fixing block 111 extending in the transverse direction toward the outside, where the outside refers to the transverse direction outward, and the trapezoidal fixing block 111 is used to connect with the baffle 120, so a connecting block 121 is convexly formed upward on the baffle 120, and the connecting block 121 is used to connect with the trapezoidal fixing block 111, wherein a trapezoidal groove 1 is formed inwardly at the top of the connecting block 121. 22. The trapezoidal groove 122 is matched with the trapezoidal fixing block 111. The matched setting here means that the cross-sectional shape and the longitudinal length of the trapezoidal groove 122 are consistent, and the trapezoidal groove 122 is set to penetrate in the transverse direction, so that the trapezoidal fixing block 111 can be freely slid and adjusted in the transverse direction when it is clamped in the trapezoidal groove 122. The technician can adjust the gap between the two baffles 120 by adjusting the baffle 120 in the transverse direction, so that the gap is consistent with the spacing between the two welding plates 40, thereby ensuring the protection effect. Since the trapezoidal groove 122 is closed in the longitudinal direction, when the welding movement is performed in the longitudinal direction, the trapezoidal fixing block 111 drives the baffle 120 to move together in the longitudinal direction under the mutual limit stop with the trapezoidal groove 122 in the longitudinal direction, thereby achieving the purpose of real-time following changes in the anti-splash range and ensuring the anti-splash effect.

[0036] As a preferred embodiment of the present invention, a threaded hole extending vertically is provided on the trapezoidal fixing block 111 , and the trapezoidal fixing block 111 is supported on the connecting block 121 by a fixing bolt 112 passing through the threaded hole to be fixedly connected with the connecting block.

[0037] It should be noted that after adjusting the spacing between the baffles 120, since the baffles 120 will move with the entire structure during welding, if the movement is too fast, it will inevitably cause the baffles 120 to shift slightly in the horizontal direction again. Therefore, fasteners can be added to fix the baffles 120 and the connecting strips 110 to each other after determining the spacing between the baffles 120. Therefore, a threaded hole extending vertically can be opened on the trapezoidal fixing block 111. When the technician manipulates the baffle 120 to move horizontally and determines the position, the fixing bolt 112 can be screwed through the threaded hole and the bottom of the bolt can be pressed against the connecting block 121 to form a large downward fixing pressure, thereby achieving mutual fixation between the connecting strip 110 and the baffle 120; in this way, the baffle 120 will not shift again when the technician is welding. If readjustment is required, the fixing bolt 112 can be loosened.

[0038] As a preferred embodiment of the present invention, the baffle 120 is L-shaped, and the baffle 120 includes a bottom baffle 123 and a side baffle 124 . The connecting block 121 is fixed on the bottom baffle 123 , and the side baffle 124 is erected on a side of the bottom baffle 123 away from the nozzle 320 .

[0039] It should be noted that, considering that the spatter generated by welding is radioactive, in addition to protecting by directly covering the welding plate 40, it is also necessary to prevent the spatter from splashing from the side to the uncovered area. Therefore, the baffle 120 can be set in an L shape, that is, it includes a bottom baffle 123 and a side baffle 124. The bottom baffle 123 is used to directly cover the welding plate 40 around the weld 410, and the side baffle 124 is used to block the spatter splashing to both sides.

[0040] As a preferred embodiment of the present invention, the bottom end of the connecting strip 110 is gradually bent outward.

[0041] It is worth noting that this can prevent the bottom end of the connecting strip 110 from being too close to the nozzle 320, thereby affecting the welding process.

[0042] As a preferred embodiment of the present invention, it further comprises a plurality of fixing bolts 210. The fixing ring 20 is provided with a plurality of through holes along its circumference, and the fixing bolts 210 are adjustably penetrated through the through holes.

[0043] It is worth noting that, taking into account the different sizes of different welding guns 30, when the diameter of the welding gun body 310 is small and causes mismatch with the fixing ring 20, the welding gun 30 and the fixing ring 20 may be unstable. Therefore, additional fixing bolts 210 can be provided at this time. By adjusting multiple fixing bolts 210 to hold them against the side wall of the welding gun body 310, the welding gun body 310 can be limited and fixed along the circumference of the fixing ring 20 to increase the stability of the connection.

[0044] Furthermore, a flexible welding pad is included, and the flexible welding pad is connected to the bottom of the bottom baffle 123 .

[0045] It should be noted that the flexible welding pad (not shown) can improve the flexibility and adaptability between the bottom baffle 123 and the welding plate 40, avoiding minor damage to the welding plate 40 due to rigid collision caused by the overly rigid structure, and after the flexible welding pad is set, the friction between the bottom baffle 123 and the welding plate 40 during welding movement can be reduced, thereby improving welding efficiency.

[0046] Furthermore, the baffle 120 is made of aluminum alloy.

[0047] It should be understood that aluminum alloy material has the advantage of being light in weight, so that it can be easily moved during welding, and it also has the property of being resistant to high temperatures, so it can better accept the spatter generated by welding.

[0048] Furthermore, the width of the bottom baffle 123 and the thickness of the side baffle 124 are both 15 cm to 20 cm.

[0049] It should be noted that the thickness can be determined according to the size of spatter generated during welding. Preferably, it can be set to 15 cm to 20 cm, and those skilled in the art can set it according to actual conditions.

[0050] Furthermore, the top end of the connecting bar 110 is fixedly connected to the fixing ring 20 by welding.

[0051] It should be noted that the welding connection method is easy to process and the connection is relatively stable.

[0052] Furthermore, the number of the through holes is two, and the two through holes are arranged at intervals along the circumference of the fixing ring 20 .

[0053] It can be understood that, the more the through holes are, the better the fastening effect of the welding gun body 310 by the fixing bolts 210 is, so as to maintain the limited fastening from all sides. Considering that the connecting strips 110 are used for limiting on both sides in the present application, preferably, the number of the through holes is two, and can also be directly set to four, so as to directly achieve the fastening effect of the welding gun body 310 from all sides.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
