Description

Technical Field

[0001] This application relates to the field of laser welding equipment technology, and in particular to a laser welding device for gaps in pipe metal parts. Background Technology

[0002] During the splicing and processing of pipe-type metal parts, when two pipes are joined together, an annular gap or an axial straight gap will be formed. Laser welding is required to seal the gap and connect the structure.

[0003] Existing laser welding equipment for pipe metal fittings mostly adopts a fixed welding torch structure during use. The welding torch position adjustment range is small and the adjustment accuracy is low, making it difficult to flexibly adapt to the welding points of different pipe specifications. At the same time, the laser welding equipment can only achieve fixed-point welding, and the pipe cannot rotate smoothly. It is difficult to complete 360-degree continuous welding for annular gaps in pipes, resulting in dead corners, poor weld integrity and welding quality. Summary of the Invention

[0020] Please see Figure 1-4 The present invention provides a technical solution: a laser welding device for gaps in pipe metal parts, comprising a bearing mechanism 1, a clamping mechanism 2 and a welding mechanism 3; The supporting mechanism 1 includes a welding table 101, a dust collection box 109 is installed inside the welding table 101, a dust collection fan 110 is installed on the top of the dust collection box 109, and an air outlet 102 is installed at the output end of the dust collection fan 110. The clamping mechanism 2 includes a clamping seat 201 installed on the top of the welding table 101. A support bracket 202 is integrally formed on the inner side of the clamping seat 201. A support roller 203 is rotatably connected to the inner side of the support bracket 202. An electric telescopic rod 204 is installed on the top of the clamping seat 201. The welding mechanism 3 includes a movable frame 301 bolted to the back of the welding table 101. The top of the movable frame 301 has a movable groove 305. The top of the movable frame 301 is slidably connected to a lifting pole 306 through the movable groove 305. The top of the lifting pole 306 is bolted to an adjusting frame 307. The bottom of the adjusting frame 307 has an adjusting groove 313. The bottom of the adjusting frame 307 is slidably connected to an adjusting plate 308 through the adjusting groove 313. A laser welding gun 309 is mounted on the top of the adjusting plate 308.

[0021] Furthermore, support legs 106 are bolted to the four corners of the bottom of the welding table 101, and control panel 103 is bolted to the front of the welding table 101. Display screen 104 and control buttons 105 are respectively installed on the front of the control panel 103. The support legs 106 provide support and stability for the overall equipment. Operators can issue various operating commands through control buttons 105, and display screen 104 displays the equipment operating parameters in real time.

[0022] Furthermore, a dust collection pipe 107 runs through one side of the welding station 101. One end of the dust collection pipe 107 is threadedly connected to a dust collection hood 108. The dust collection pipe 107 is fixedly connected to the adjustment plate 308. The dust collection hood 108 moves synchronously with the laser welding gun 309, which can collect the welding fumes at close range. The fumes are transported through the dust collection pipe 107 to the inside of the dust collection structure for purification.

[0023] Furthermore, the bottom end of the electric telescopic rod 204 is bolted to a fixed bracket 205, and a fixed cylinder 206 is rotatably connected to the inner side of the fixed bracket 205. A rotary motor 207 is installed on one side of the fixed bracket 205, and the rotary motor 207 is keyed to the fixed cylinder 206. The electric telescopic rod 204 drives the fixed cylinder 206 to press down and clamp the pipe. The rotary motor 207 can drive the fixed cylinder 206 to rotate, thereby driving the pipe to rotate synchronously, realizing all-round welding of the annular gap.

[0024] Furthermore, a mobile motor 302 is installed on one side of the mobile frame 301. The drive end of the mobile motor 302 is fixed with a mobile screw 303 via a coupling. A mobile nut seat 304 is threadedly connected to the outer side of the mobile screw 303. The mobile nut seat 304 is bolted to the lifting pole 306. Starting the mobile motor 302 can drive the mobile screw 303 to rotate, and through the mobile nut seat 304, drive the lifting pole 306 and the laser welding gun 309 to move left and right, thus completing the lateral position adjustment.

[0025] Furthermore, an adjustment motor 310 is installed inside the adjustment frame 307. The drive end of the adjustment motor 310 is fixed with an adjustment screw 311 via a coupling. An adjustment nut seat 312 is threadedly connected to the outer side of the adjustment screw 311. The adjustment nut seat 312 is bolted to the adjustment plate 308. By starting the adjustment motor 310, the adjustment motor 310 drives the adjustment screw 311 to rotate. Through the adjustment nut seat 312, the adjustment plate 308 slides back and forth along the adjustment groove 313 of the adjustment frame 307, thereby making fine adjustments to the horizontal position of the laser welding gun 309.

[0026] Working principle: When using the laser welding device for gaps in pipe metal parts, the operator first places the metal pipe to be welded on the support roller 203 of the clamping mechanism 2; then, the electric telescopic rod 204 is started through the control panel 103. The electric telescopic rod 204 drives the bottom fixed bracket 205 to move down, so that the fixed cylinder 206 presses the pipe, completing the positioning and clamping of the pipe.

[0027] After the pipe is fixed, the moving motor 302 is started, driving the moving screw 303 to rotate. This, in conjunction with the moving nut seat 304, causes the lifting rod 306 to move left and right along the moving groove 305 on the moving frame 301. Simultaneously, the adjusting motor 310 is started, driving the adjusting screw 311 to rotate. This, via the adjusting nut seat 312, causes the adjusting plate 308 to slide back and forth along the adjusting groove 313 of the adjusting frame 307, thereby fine-tuning the horizontal position of the laser welding gun 309. Combined with the lifting motion of the lifting rod 306, the vertical height adjustment of the laser welding gun 309 is completed, ultimately ensuring that the laser welding gun 309 is precisely aligned with the welding seam of the pipe.

[0028] During the formal welding operation, the rotary motor 207 is started, which drives the fixed cylinder 206 to rotate. Due to friction, the clamped pipe rotates synchronously, realizing the circumferential rotation of the pipe. The equipment can perform 360-degree continuous welding on the pipe gap, ensuring the integrity of the annular gap welding.

[0029] Throughout the welding process, the dust collection fan 110 inside the bearing mechanism 1 works continuously, creating a negative pressure at the dust collection hood 108. The welding fumes are collected by the dust collection hood 108 and then transported through the dust collection pipe 107 to the dust collection box 109 for filtration and purification. The purified air is finally discharged from the air outlet 102, effectively improving the working environment.

[0030] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
