Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and more specifically, particularly relates to an electric welding equipment for building metal parts in construction engineering. Background Art

[0002] In the field of welding building metal parts, there are multiple technical bottlenecks in traditional electric welding equipment that urgently need to be broken through. First of all, metal oxides (such as Fe 2 O 3 , MnO) and volatile organic compounds (such as NOx, CO) in the welding fumes generated by traditional flat workbenches are prone to diffuse in the working environment, which not only endangers the respiratory health of workers but may also cause occupational diseases such as metal fume fever. Secondly, metal spatter accumulates on the workbench surface under the action of gravity, which not only increases the fire risk but also leads to waste of resources, and the manual cleaning process is cumbersome and inefficient. Moreover, the positioning layout of the robotic arm of traditional equipment is fixed and cannot adapt to the complex shapes of welded parts and dynamic welding requirements, often resulting in problems such as disordered airflow fields and occlusion of the welding area, affecting welding quality and construction efficiency.

[0003] In response to the above pain points, the present invention realizes efficient collection of welding fumes, resource utilization of waste chips, high adaptability of the equipment, and convenient maintenance through the collaborative design of a diamond grid plate and a filtration system, combined with dynamic positioning and a modular structure, providing an innovative solution for the green and intelligent development in the field of building welding.

[0020] Preferably, a rubber anti-slip pad is fixedly connected to the bottom of the end of the sliding plate. A strip-shaped groove is formed on the upper surface of the sliding plate. Both ends of the strip-shaped groove are circular ends. Guide grooves are formed on both sides of the strip-shaped groove. A connecting groove is formed directly below the adjusting screw. The strip-shaped groove and the two guide grooves are connected to an annular groove on the side close to the splicing plate. A sheath is also fixedly connected to the second cross bar.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, during the welding process, metal spatters such as welding chips generated fall downward through the pores on the diamond grid plate to the arc surface of the bottom of the collecting trough. Under the action of gravity and the scraper, they fall into the annular plate through the gap between the circular groove and the conveying pipe and accumulate on the baffle plate, thereby collecting the metal spatters and facilitating recycling.

[0023] In the present invention, during the welding process, when the metal parts are different and the cutting positions are different, in order to maintain the best smoke removal effect, the operator can push the push piece with the toes. At this time, the guide rod slides along the fixed piece to compress the spring. When the limit seat is disengaged from the circular slot, the bottom mounting shell loses the limit. At this time, the bottom mounting shell can be rotated, and the bottom mounting shell drives the conveying pipeline to rotate, thereby driving the collecting funnel to move to a position close to the welding point, and release the push piece. Under the elastic force of the spring, the push piece is reset, and the limit seat is clamped with the circular slot at the corresponding position again, so as to achieve the effect of fixing the position of the bottom mounting shell again.

[0024] In the present invention, after the position of the collecting funnel is determined, when welding begins, the fan is started to exhaust air, and a negative pressure is formed at the collecting funnel through the conveying pipe. The smoke generated by welding is sucked into the conveying pipe through the collecting funnel, and is conveyed through the gradient pore metal wire mesh and the nanofiber membrane composite layer for filtration and purification. Finally, the purified gas is discharged through the air outlet at the lower end of the fan and discharged through the mesh structure at the lower end of the splicing plate. The discharge direction is opposite to that of the collecting funnel, thereby minimizing the impact on the welding area.

[0025] In the present invention, metal spatters falling on the screen during welding roll down along the slope of the screen into the collecting trough to prevent the spatters from entering the collecting funnel. The baffle closes the guide cylinder to prevent the collecting funnel from extracting gas passing through the guide cylinder, blowing up the smiling spatters and dust scattered in the collecting trough to cause dust. When a lot of spatters are accumulated on the baffle, the baffle can be loosened by turning the fixing screw, and the baffle can be pulled by pulling the pull ring to make the accumulated spatters fall into the collecting box. By toggling the baffle rod, the baffle rod can no longer restrict the collecting box, and the connecting strip slides along the connecting piece, which is convenient for disassembly and assembly of the collecting box and collection and cleaning of the spatters.

[0026] In the present invention, when it is necessary to clean or replace the composite layer of the gradient pore metal wire mesh and the nanofiber membrane, the adjusting screw is rotated to disengage it from the threaded groove and the connecting groove. At this time, the splicing plate can be pulled by holding the rod. During this process, the cylinder slides along the strip-shaped groove, and the two sliders slide along the two guiding grooves respectively until the cylinder slides to the other end of the strip-shaped groove. At this time, the sliders can slide along the annular groove to cooperate with the rotation of the splicing plate. The operator can rotate the splicing plate to make the composite layer of the gradient pore metal wire mesh and the nanofiber membrane rotate to the outward state without the operator climbing under the welding workbench surface, which is convenient for the operator to replace and clean the composite layer of the gradient pore metal wire mesh and the nanofiber membrane. The rubber anti-slip pad rubs against the first cross bar, making the reversed splicing plate not easy to shake and deflect, improving the stability.

[0027] In the present invention, in order to further improve the applicability, the operator can rotate the positioning screw to disengage it from the positioning hole. At this time, the moving seat can be slid along the guide rail, and then the moving seat can be repositioned by using the positioning hole and the positioning screw. The position switching of the moving seat can avoid the moving seat affecting the welding at a specific position and avoid affecting the positioning of the bottom mounting shell.

The gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59 are both circular structures and are hermetically fitted to the inner wall of the bottom mounting housing 4. When the bottom mounting housing 4 and the splicing plate 5 are spliced together, they form a complete circular cylinder.

[0055] During welding, metal spatters falling on the screen 73 roll down along the slope of the screen 73 into the collection tank 6 to prevent the spatters from entering the collection funnel 72. The baffle 24 closes the guide cylinder 32 to prevent the collection funnel 72 from extracting the gas passing through the guide cylinder 32 and blowing up the spatters and dust scattered in the collection tank 6 to cause dust. When there are a lot of spatters accumulated on the baffle 24, the baffle 24 can be loosened by rotating the fixing screw 27, and the pull ring 26 can be pulled to pull the baffle 24, so that the accumulated spatters fall into the collection box 20. By toggling the baffle rod 28, the baffle rod 28 can no longer limit The collecting box 20 is made, and the connecting strip 21 slides along the connecting piece 29, which is convenient for disassembly and assembly of the collecting box 20 and collection and cleaning of splashes. The bottom of the end of the slide plate 45 is fixedly connected with a rubber anti-skid pad 52. The upper surface of the slide plate 45 is provided with a strip groove 53.

The strip groove 53 and the two guide grooves 54 are connected with an annular groove 57 on one side close to the splicing plate 5. A sheath 69 is also fixedly connected to the second crossbar 67. During the welding process, when the metal parts are different and When the cutting position is different, in order to maintain the best smoke removal effect, the operator can push the push piece 62 with the toe, at this time the guide rod 65 slides along the fixing piece 66, compressing the spring, and when the limit seat 63 is out of the circular slot 18, the bottom mounting shell 4 loses the limit, and the bottom mounting shell 4 can be rotated at this time, and the bottom mounting shell 4 drives the conveying pipe 70 to rotate, thereby driving the collecting funnel 72 to move to a position close to the welding position, and release the push piece 62, and the push piece 62 is reset under the elastic force of the spring, and the limit seat 63 is engaged with the circular slot 18 at the corresponding position again, so as to fix the bottom mounting shell again. The effect of the position of the shell 4 is that after the position of the collecting funnel 72 is determined, when welding starts, the fan 39 is started, and the fan 39 is exhausted to form a negative pressure at the collecting funnel 72 through the conveying pipe 70. The smoke generated by welding is sucked into the conveying pipe 70 through the collecting funnel 72, and is conveyed through the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59 for filtration and purification. Finally, the purified gas is discharged through the air outlet at the lower end of the fan 39 and discharged through the mesh structure at the lower end of the splicing plate 5. The discharge direction is opposite to the direction of the collecting funnel 72, so as to avoid the influence on the welding area to the greatest extent.

[0056] When it is necessary to clean or replace the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59, rotate the adjusting screw 46 to disengage it from the threaded groove 41 and the connecting groove 56. At this time, the splicing plate 5 can be pulled by the handle 47. During this process, the cylinder 44 slides along the strip-shaped groove 53, and the two sliders 43 slide along the two guiding grooves 54 respectively until the cylinder 44 slides to the other end of the strip-shaped groove 53. At this time, the slider 43 can slide along the annular groove 57 to cooperate with the rotation of the splicing plate 5. The operator can rotate the splicing plate 5 to turn the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59 to the outward state without the operator climbing under the electric welding workbench surface 1, which is convenient for the operator to replace and clean the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59. The rubber anti-slip pad 52 frictions the cross bar 38 so that the reversed splicing plate 5 is not easy to shake and deflect, improving the stability; To further improve the applicability, the operator can rotate the positioning screw 15 to disengage it from the positioning hole 11. At this time, the moving seat 2 can slide along the guide rail 10, and then the moving seat 2 can be repositioned by using the positioning hole 11 and the positioning screw 15. The position switching of the moving seat 2 can avoid the moving seat 2 affecting the welding at a specific position and avoid affecting the positioning of the bottom mounting shell 4.

[0057] Working principle:

[0058] During use, place the building metal parts to be welded on the diamond grid plate 7, and control the electric welding robotic arm 13 for welding. The waste gas, smoke, and waste chips generated during the welding process are collected through the pores on the diamond grid plate 7 and in cooperation with the negative pressure field generated by the fan 39, improving the visibility of the welding area, significantly improving the welder's operation line of sight, reducing the weld defect rate, and making the waste chips collected together convenient for recycling and reuse. Specifically as follows:

[0059] During the welding process, the metal spatter such as welding chips falls downward through the pores on the diamond grid plate 7 to the bottom arc surface of the collection groove 6. Under the action of gravity and the scraper 71, it falls into the annular plate 33 through the gap between the circular groove 8 and the conveying pipe 70 and accumulates on the baffle 24 for collecting the metal spatter, which is convenient for recycling.

[0060] During the welding process, when the metal parts are different and the cutting positions are different, in order to keep the smoke removal effect optimal, the operator can push the push piece 62 with the toe. At this time, the guide rod 65 slides along the fixed piece 66, compressing the spring. When the limit seat 63 disengages from the circular card slot 18, the bottom mounting shell 4 loses its limit. At this time, the bottom mounting shell 4 can be rotated, and the bottom mounting shell 4 drives the conveying pipe 70 to rotate, thereby driving the collection funnel 72 to move to a position close to the welding area, and then release the push piece 62. Under the elastic force of the spring, the push piece 62 resets, and the limit seat 63 is again clamped with the circular card slot 18 at the corresponding position, achieving the effect of fixing the position of the bottom mounting shell 4 again.

[0061] After the position of the collecting funnel 72 is determined, when welding begins, the fan 39 is started, and the fan 39 is used for exhaust, and a negative pressure is formed at the collecting funnel 72 through the conveying pipe 70. The smoke generated by welding is sucked into the conveying pipe 70 through the collecting funnel 72, and is conveyed through the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59 for filtration and purification. Finally, the purified gas is discharged through the air outlet at the lower end of the fan 39, and is discharged through the mesh structure at the lower end of the splicing plate 5. The discharge direction is opposite to the direction of the collecting funnel 72, so as to avoid the influence on the welding area to the greatest extent.

[0062] During welding, metal spatters falling on the screen 73 roll down along the slope of the screen 73 into the collection tank 6 to prevent the spatters from entering the collection funnel 72. The baffle 24 closes the guide cylinder 32 to prevent the collection funnel 72 from extracting the gas passing through the guide cylinder 32 and blowing up the spatters and dust scattered in the collection tank 6 to cause dust. When there are a lot of spatters accumulated on the baffle 24, the baffle 24 can be loosened by rotating the fixing screw 27, and the pull ring 26 can be pulled to pull the baffle 24, so that the accumulated spatters fall into the collection box 20. By toggling the baffle rod 28, the baffle rod 28 can no longer restrict the collection box 20, and the connecting strip 21 slides along the connecting piece 29, which is convenient for disassembly and assembly of the collection box 20 and collection and cleaning of spatters.

[0063] When it is necessary to clean or replace the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59, the adjusting screw 46 is rotated to disengage the threaded groove 41 and the connecting groove 56. At this time, the splicing plate 5 can be pulled by the handle 47. During this process, the cylinder 44 slides along the strip groove 53, and the two sliders 43 slide along the two guide grooves 54 respectively until the cylinder 44 slides to the other end of the strip groove 53. At this time, the slider 43 can slide along the annular groove 57 to cooperate with the rotation of the splicing plate 5. The operator can rotate the splicing plate 5 to rotate the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59 to an outward state without the operator having to climb under the electric welding workbench 1, which is convenient for the operator to replace and clean the gradient pore metal wire mesh 58 and the nanofiber membrane composite layer 59. The rubber anti-slip pad 52 rubs against the cross bar 38, so that the reversed splicing plate 5 is not easy to shake or deflect, thereby improving stability.

[0064] In order to further improve the applicability, the operator can rotate the positioning screw 15 to disengage it from the positioning hole 11. At this time, the mobile seat 2 can be slid along the guide rail 10, and then the positioning hole 11 and the positioning screw 15 can be used to re-position the mobile seat 2. The position switching of the mobile seat 2 can prevent the mobile seat 2 from affecting the welding at a specific position and avoid affecting the positioning of the bottom mounting shell 4.
