Description

Technical Field

[0001] This utility model relates to the field of welding protection technology, specifically a side protection mechanism for metal welding. Background Technology

[0002] During metal welding, high-temperature molten slag sputtering occurs in the weld seam. Unlike open spaces, when welding cylindrical workpieces in confined areas or areas with potential safety hazards, the sputtering of high-temperature molten slag needs to be controlled within a manageable range to avoid affecting surrounding or other components. Side protection mechanisms can effectively reduce the range of high-temperature molten slag sputtering and improve the safety of welding operations.

[0003] Currently, when performing repair welding operations on cylindrical workpieces in narrow areas, the welding torch oscillates significantly as it sprays towards the workpiece surface and assists in welding the cracked area. Furthermore, the limited space makes it difficult for existing side protection mechanisms to keep up with the moving welding torch nozzle in real time. As a result, welding is significantly limited, and the narrow space also affects the welding accuracy of the workers.

[0004] In view of this, a side protection mechanism for metal welding was designed to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A side protection mechanism for metal welding includes a welding torch, a welding distance adjustment mechanism mounted on the welding torch, and two sets of slag blocking mechanisms mounted on the welding distance adjustment mechanism. The welding distance adjustment mechanism includes two outer shells mounted on a section of the welding torch tube. Each outer shell has a load-bearing pad, and the load-bearing pad has a groove. A cantilever is movably mounted within the groove, and a clamp is mounted on the cantilever. A bidirectional lead screw is movably mounted at the middle of two adjacent load-bearing pads. A sliding sleeve is threaded onto the bidirectional lead screw, and two traction frames are movably connected to the sliding sleeve. The other end of each traction frame is movably mounted on the clamp. The slag blocking mechanism includes a stud mounted at the bottom end of the cantilever. A stabilizing plate is mounted on the outside of the stud, and a heat insulation plate is disposed inside the stabilizing plate.

[0008] In a preferred embodiment, the present invention can be further configured such that: an inner pad is fixedly installed on the inner wall of the outer shell, and the number of inner pads is two, and four symmetrically distributed combination bolts are installed in the two outer shells.

[0009] In a preferred embodiment, the present invention can be further configured such that: a semi-cylindrical groove is provided on the inner side of the bottom end of the load-bearing pad, the top section of the bidirectional lead screw is movably installed in two semi-cylindrical grooves, and a rotating wheel is fixedly installed at the bottom end of the bidirectional lead screw.

[0010] In a preferred embodiment, the present invention can be further configured such that: a nut is installed on the threaded section of the stud, and washers are inserted into the outside of the two studs, and the washers are adapted to fit against the outer surface of the cantilever.

[0011] In a preferred embodiment, the present invention can be further configured such that: both ends of the stabilizing plate are provided with through holes, and bolts are inserted into the through holes, the bolts being threaded into threaded holes at the bottom of the heat insulation plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: the heat insulation plate is in the form of a fan shape, the two heat insulation plates are located on both sides of the welding torch nozzle, and are pressed against the outer surface of the cylindrical workpiece.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. This utility model involves installing a welding control mechanism on the pipe section of an existing welding torch. The welding torch control mechanism then assembles a slag blocking mechanism directly below the welding torch nozzle. It utilizes a bidirectional screw adjusting sleeve and two traction frames for relative extension until two cantilever arms control two heat insulation plates to adjust the gap between the cylindrical workpiece cracks. As the cylindrical workpiece cracks are welded, the sputtered high-temperature slag is confined within a controllable gap, preventing safety hazards to the environment or equipment outside the cylindrical workpiece.

[0015] 2. This utility model provides effective stabilization support for the welding torch by opening arc-shaped slots at the bottom of the two heat insulation plates. After the gap between the two heat insulation plates is adjusted, the heat insulation plates acting on the outer surface of the cylindrical workpiece will ensure that the nozzle of the welding torch and the crack of the cylindrical workpiece always maintain a constant distance, thus ensuring the effectiveness of workpiece welding and improving welding accuracy.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a side protection mechanism for metal welding.

[0028] Example 1:

[0029] Combination Figures 1 to 5 As shown, the present invention provides a side protection mechanism for metal welding, including a welding torch 100, a welding distance adjustment mechanism 200 mounted on the welding torch 100, and two sets of slag blocking mechanisms 300 mounted on the welding distance adjustment mechanism 200. The welding distance adjustment mechanism 200 provides an effective support platform for the two sets of slag blocking mechanisms 300 and a stable bearing platform for the welding torch 100. After the gap between the two sets of slag blocking mechanisms 300 is adjusted, it is convenient to provide protection against large-scale sputtering of high-temperature slag.

[0030] The welding distance adjustment mechanism 200 includes two outer shells 210 installed on the pipe section of the welding torch 100. A load-bearing pad 220 is installed on the outer shell 210, and a sliding groove 2201 is opened in the load-bearing pad 2201. A cantilever 230 is movably installed in the sliding groove 2201, and a clamp 2301 is installed on the cantilever 230. A double-acting screw 240 is movably installed in the middle of two adjacent load-bearing pads 220. A sliding sleeve 250 is threaded on the double-acting screw 240. Two traction frames 260 are movably connected to the sliding sleeve 250, and the other end of the traction frame 260 is movably installed on the clamp 2301.

[0031] An inner gasket 2101 is fixedly installed on the inner wall of the outer shell 210, and there are two inner gaskets 2101. Four symmetrically distributed combination bolts 2102 are installed inside the two outer shells 210.

[0032] The inner side of the bottom end of the load-bearing pad 220 is provided with a semi-cylindrical groove, the top section of the bidirectional screw 240 is movably installed in the two semi-cylindrical grooves, and a rotating wheel is fixedly installed at the bottom end of the bidirectional screw 240.

[0033] The slag blocking mechanism 300 includes a stud 320 installed at the bottom of the cantilever 230, a stabilizing plate 310 installed on the outside of the stud 320, and a heat insulation plate 340 installed inside the stabilizing plate 310.

[0034] Preferably, after the two outer shells 210 are locked and fixed by four combination bolts 2102, the two symmetrically distributed inner pads 2101 are squeezed to enhance the stability of the welding gun 100 pipe section, while the plate end of the top of the load-bearing pad 220 is fixed to the rod section outside the outer shell 210, and the top of the cantilever 230 is provided with a T-shaped slider, and the cantilever 230 is movably installed in the slide groove 2201 through its top T-shaped slider;

[0035] As the bottom wheel of the bidirectional lead screw 240 is rotated, the bidirectional lead screw 240, after rotating in the forward direction, will help the sliding sleeve 250 descend at a constant speed. Finally, the sliding sleeve 250 will pull the two traction frames 260 to retract, and the two stretched cantilevers 230 will drive the two sets of slag blocking mechanisms 300 to quickly retract around the nozzle of the welding torch 100. Finally, the two heat insulation plates 340 after retraction can provide high-temperature slag sputtering protection for the welding area of ​​the crack in the cylindrical workpiece, avoiding the safety hazards caused by high-temperature slag in the narrow area.

[0036] Example 2:

[0037] Combination Figure 5 As shown, in the above embodiment, a nut 3201 is installed on the threaded section of the stud 320, and a washer 3202 is inserted into the outside of the two studs 320, and the washer 3202 is adapted to fit against the outer surface of the cantilever 230.

[0038] Both ends of the stabilizing plate 310 are provided with through holes, and bolts 330 are inserted into the through holes. The bolts 330 are threaded and installed in the threaded holes at the bottom of the heat insulation plate 340. The heat insulation plate 340 is in the shape of a fan. The two heat insulation plates 340 are located on both sides of the nozzle of the welding gun 100 and are pressed against the outer surface of the cylindrical workpiece.

[0039] Preferably, the four corners of the heat insulation plate 340 are rounded to reduce scratches on the outer surface of the cylindrical workpiece and improve the sliding efficiency of the heat insulation plate 340 along the outer surface of the cylindrical workpiece.

[0040] When a worker holds the welding torch 100 handle and controls its outer nozzle to aim at the crack in the cylindrical workpiece, by controlling the rotation angle of the welding torch 100 handle, its outer nozzle will be supported by two heat insulation plates 340 to ensure the accuracy of welding the crack in the cylindrical workpiece, making it convenient for workers to perform efficient welding operations on cylindrical workpieces in a narrow area.

[0041] The working principle and usage process of this utility model are as follows: Before use, the two inner pads 2101 and the two outer shells 210 are clamped on the pipe section of the welding torch 100, and the two outer shells 210 are fixed and locked with multiple combination bolts 2102. Then, the wheel at the bottom of the bidirectional screw 240 is rotated until the bidirectional screw 240 rotates forward and pushes the sliding sleeve 250 to rise. The sliding sleeve 250 will push the two traction frames 260 to extend outward. Finally, the two symmetrically distributed clamps 2301 and the two cantilever arms 230 will expand outward synchronously with the nozzle of the welding torch 100 as the center.

[0042] When in use, when the worker holds the welding torch 100 handle and points its outer nozzle toward the crack of the cylindrical workpiece, the two heat insulation plates 340 located on both sides of the cylindrical workpiece provide protection against lateral spatter of the molten slag generated during welding. As the welding torch 100 slides or rotates along the outer surface of the cylindrical workpiece, the two heat insulation plates 340 symmetrically distributed along the outer nozzle of the welding torch 100, after adjusting the gap, will constrain the spattered molten slag within a controllable range, ensuring that the molten slag will not cause safety hazards to areas outside the crack of the cylindrical workpiece.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
