Description

Technical Field

[0001] This invention relates to the field of pump casing welding technology, specifically to a welding device for the production and processing of water pump casings. Background Technology

[0002] As a core piece of equipment in the field of fluid transportation, water pumps are widely used in many industries such as industrial production, municipal water supply, agricultural irrigation, and water conservancy projects. In the actual production and processing of water pump casings, welded pump casings are widely used. At the same time, the water pump casing plays an important role in protecting the internal impeller, sealing the fluid, and guiding the flow of the medium. Therefore, it has extremely high requirements for welding quality. When welding water pump casings, the main structure of the casing is usually made by welding a metal outer ring and an end plate. It is necessary to weld the inner and outer welds of the metal outer ring separately. Current welding equipment used in the production and processing of water pump casings typically requires a clamping structure to hold the pump casing parts to be welded before welding. However, pump casing welding usually involves welding both sides of the weld seam. Traditional clamping structures are not convenient for quick side-to-side welding and can also obstruct the weld seam, requiring tedious manual adjustments to ensure unobstructed weld lines, thus affecting welding efficiency. In addition, traditional flip-up clamping structures usually require controlling the laser welding head to move and avoid collisions during flipping to prevent damage. However, workers may flip the clamp before the laser welding head has fully moved and avoided collisions due to factors such as flipping too quickly, causing damage and making collision protection difficult to implement.

An obstacle avoidance switch located behind the flip-up component restricts the laser welding head's position until it is behind the flip-up component, preventing damage to the laser welding head and thus avoiding economic losses during rotation.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: such as Figures 1 to 10The welding device shown includes a welding mounting component 1, a flipping component 2 mounted on the welding mounting component 1 for switching welding surfaces; a positioning component 3 mounted on the welding mounting component 1 for positioning the flipping component 2; a clamping device 4 mounted on the flipping component 2 for clamping the water pump casing; a clamping control component 5 mounted on the flipping component 2; and a combined clamping component 6 mounted on the flipping component 2 for indicating the assembly accuracy of the water pump casing parts. The welding mounting component 1 includes a support plate 101, a switch plate 102, and an avoidance switch 103. A rubber pad is provided on the support plate 101; the switch plate 102 is fixedly mounted on the support plate 101 by bolts; the avoidance switch 103 is fixedly mounted on the switch plate 102; and the avoidance switch 103 is located behind the flipping component 2.

[0020] The welding mounting component 1 further includes: a positioning electromagnet 104; through holes for bolts are provided on both sides of the support plate 101; the positioning electromagnet 104 is fixedly mounted on the support plate 101; and an avoidance switch 103 is electrically connected to the positioning electromagnet 104. The flipping component 2 includes: a flipping plate 201, a pump housing slot 2011, positioning holes 2012, a displacement electromagnet 202, and an electromagnet core 203; the flipping plate 201 is rotatably mounted on the support plate 101; a pump housing slot 2011 is provided on the flipping plate 201; the pump housing slot 2011 is used to insert the pump housing to be welded; two positioning holes 2012 are provided on each side of the flipping plate 201, and all four positioning holes 2012 are... A chamfer is provided; a displacement electromagnet 202 is fixedly installed on the support plate 101; an electromagnet core 203 is inserted into the middle of the displacement electromagnet 202; a flip plate 201 is used to switch the welding surface; the positioning component 3 includes: a connecting plate 301, a positioning shaft 3011, and a positioning spring 302. Two positioning shafts 3011 are fixedly installed on the connecting plate 301, and the two positioning shafts 3011 are slidably inserted into the support plate 101 respectively; the two positioning shafts 3011 are respectively inserted into two positioning holes 2012 on the same side; positioning springs 302 are respectively sleeved on the two positioning shafts 3011, and the ends of the two positioning springs 302 are respectively connected to the connecting plate 301; the two positioning springs 302... The other end is connected to the support plate 101; the positioning electromagnet 104 is used to magnetically attach the connecting plate 301; when the two positioning shafts 3011 are inserted into the two positioning holes 2012 on the same side, the flip plate 201 is in a horizontal state; the flipping part 2 can easily flip and switch the welding surface of the pump shell, without the need for tedious disassembly of the pump shell assembly for face changing. With the positioning part 3, the flipping part 2 can be quickly positioned to ensure the stability of the flipping part 2 after face changing and to ensure the welding processing accuracy. At the same time, the avoidance switch 103 is located behind the flipping part 2 to limit the position of the laser welding head to be behind the flipping part 2, so that when the flip plate 201 needs to be rotated, the positioning electromagnet 104 can be positioned. 04. Power off and normal removal of the positioning shaft 3011 can prevent damage to the laser welding head caused by forgetting to control the laser welding head displacement or rotating the flip plate 201 before the laser welding head has fully moved to the avoidance switch 103 when rotating the flip plate 201, resulting in economic loss. When it is necessary to rotate the flip plate 201 to change the face, it is also necessary to control the laser cutting head to move backward and press the avoidance switch 103. At this time, the avoidance switch 103 can control the positioning electromagnet 104 to be de-energized. At this time, the positioning electromagnet 104 no longer magnetically attracts the connecting plate 301, and can normally pull the connecting plate 301, driving the positioning shaft 3011 to be pulled out from the positioning socket 2012, thus releasing the positioning.

[0021] The clamping device 4 includes: a clamping plate 401, a clamping guide groove 4011, and a clamping pressure port 4012. Two clamping plates 401 are provided, and the two clamping plates 401 are slidably mounted on the flip plate 201. The clamping ends of the two clamping plates 401 are respectively adapted to the shapes of the two sides of the pump casing to be welded. The two clamping plates 401 are each provided with a clamping guide groove 4011, and the two clamping guide grooves 4011 are respectively obliquely positioned. A clamping pressure port 4012 is fixedly installed on each of the two clamping plates 401, and the bottom edge of the clamping pressure port 4012 is chamfered. The clamping pressure port 4012 is used for limiting... The edge of the pump casing to be welded is located; the clamping device 4 also includes: control rods 402 and clamping drive columns 403. Two control rods 402 are slidably mounted on the flip plate 201, and clamping drive columns 403 are fixedly mounted on the two control rods 402 respectively, and the two clamping drive columns 403 are respectively located in two clamping guide grooves 4011; the bottoms of the two control rods 402 are respectively attached to the two clamping plates 401; the clamping device 4 also includes: clamping connecting rod 404 and clamping tension spring 405. The clamping connecting rod 404 is slidably mounted on the flip plate 201; the ends of the two control rods 402 are respectively fixedly mounted on the clamping connecting rod. On 404; a clamping spring 405 is fixedly installed on the clamping link 404, and the end of the clamping spring 405 is fixedly installed inside the flip plate 201; the clamping spring 405 is used to pull the clamping link 404 to slide on the flip plate 201; the end of the electromagnet core 203 is fixedly installed on the clamping link 404; the clamping control component 5 includes: a pressing protrusion 501 and a power-off switch 502, the pressing protrusion 501 is fixedly installed on the flip plate 201; the power-off switch 502 is fixedly installed on the support plate 101; the end of the pressing protrusion 501 has an arc-shaped structure; the pressing protrusion 501 is used to press the power-off switch 502; The power-off switch 502 is electrically connected to the displacement electromagnet 202. The clamping control component 5 can automatically control the clamping device 4 to position and clamp the outer ring and end plate of the pump casing to be welded. It can adapt to the shape of the pump casing and ensure welding accuracy. At the same time, this structure adopts an automatically controlled clamping device 4. When performing double-sided welding of the pump casing, the clamping device 4 will not block the weld path. At the same time, the operator does not need to manually change the clamping method, which can be more efficient. After the inner weld of the pump casing is completed, the welding of the outer ring can be carried out more quickly. The structure is more reasonable, the pump casing is stable throughout the process, and the welding accuracy is high.When the rotating flip plate 201 is rotated, the extrusion protrusion 501 stops pressing the power-off switch 502. The power-off switch 502 then controls the displacement electromagnet 202 to de-energize, and it stops magnetically attracting the electromagnet core 203. Under the pull of the clamping tension spring 405, the clamping connecting rod 404 drives the clamping drive columns 403 on the two control rods 402 to move together. Utilizing the inclined opening of the clamping guide groove 4011, the two clamping plates 401 are then moved inward by the clamping drive columns 403. This, in conjunction with the clamping pressure port 4012, limits and clamps the outer ring of the pump casing and the pump casing end plate to be welded. After the inner weld is completed, the rotating flip plate 201 is rotated again to change the face. At this time, the extrusion protrusion 501 presses the power-off switch 502 again, and the corresponding two clamping plates 401 expand, no longer adhering to the pump casing. Welding work on the outer weld line of the pump casing can then be performed directly through the laser welding head.

[0022] The combined clamping component 6 includes: a clamping lower pressure plate 601, a lower pressure shaft 6011, and a lower pressure spring 602. The lower pressure shaft 6011 is fixedly installed at the bottom of the clamping lower pressure plate 601, and the lower pressure shaft 6011 is a hexagonal prism. The lower pressure shaft 6011 is slidably inserted into the flip plate 201. The bottom of the clamping lower pressure plate 601 is pressed against the upper surface of the pump housing to be welded. A handle is provided on the clamping lower pressure plate 601. The lower pressure spring 602 is sleeved on the lower pressure shaft 6011. One end of the lower pressure spring 602 is connected to the lower pressure shaft 6011, and the other end of the lower pressure spring 602 is connected to the bottom of the flip plate 201. The combined clamping component 6 also includes: a lower pressure switch 603. The pressure switch 603 is fixedly installed at the bottom of the clamping pressure plate 601; the end of the pressure switch 603 is pressed against the flip plate 201; the pressure switch 603 is electrically connected to the positioning electromagnet 104; the combined clamping component 6 can easily press the outer ring of the pump casing to be welded and the pump casing end plate, improving the stability when rotating the flip plate 201 to change the face. At the same time, in conjunction with the pressure switch 603, it can facilitate the detection of the clamping accuracy of the pump casing to be welded, avoiding direct welding if the outer ring of the pump casing is not installed in place; it can ensure that the laser focus of the laser welding head is focused on the weld when welding the weld seam in the future. The structure and operation are simple, improving the welding quality of the pump casing and reducing the welding defect rate.

[0023] Working principle: By bolting through the through holes in the support plate 101, the support plate 101 is installed in the reserved mounting position on the laser welding machine. The clamping lower pressure plate 601 is pulled upward, and then the outer ring of the pump housing is inserted into the pump housing slot 2011. The end plate of the pump housing is placed against the outer ring of the pump housing. After releasing the clamping lower pressure plate 601, the lower pressure spring 602 can elastically squeeze the lower pressure shaft 6011, causing the clamping lower pressure plate 601 to press against the surface of the end plate of the pump housing. The clamping lower pressure plate 601 is in the outlet position of the pump housing, which does not interfere with the pump housing welding. At the same time, if the outer ring of the pump housing cannot be fully inserted into the pump housing slot 2011 due to factors such as the presence of iron filings in the pump housing slot 2011 or the tortuosity of the outer ring of the pump housing, the height of the clamping lower pressure plate 601 will increase accordingly. The end of the corresponding lower pressure switch 603 cannot be pressed against the flip plate 201. It is necessary to ensure that the outer ring of the pump housing is installed in place before the end of the lower pressure switch 603 can be pressed against the flip plate 201. Only when the flip plate 201 is rotated can the positioning electromagnet 104 be de-energized, releasing the magnetic attraction protection. This allows workers to easily monitor the clamping progress and ensures the quality of subsequent welding. When the flip plate 201 needs to be rotated to change sides, the laser cutting head needs to be controlled to move backward and press the avoidance switch 103. At this time, the avoidance switch 103 can control the positioning electromagnet 104 to be de-energized. The positioning electromagnet 104 will no longer magnetically attract the coupling plate 301 and can normally pull the coupling plate 301, causing the positioning shaft 3011 to be pulled out from the positioning insertion hole 2012, releasing the positioning. After the flip plate 201 is rotated, the coupling plate 301 is released. Under the pull of the positioning tension spring 302, the positioning shaft 3011 can be inserted into the positioning insertion hole 2012 on the other side for positioning. If the workers confirm that the laser welding head has pressed the avoidance switch 103, but the positioning electromagnet 104 is still magnetically attracting the coupling plate 301, it indicates that the pump casing to be welded has not been installed properly. After the outer ring and end plate of the pump casing are clamped and pressed stably by the pressure plate 601, the extrusion protrusion 501 is in the position of the extrusion power-off switch 502. At this time, the displacement electromagnet 202 is energized and attracts the electromagnet core 203. The electromagnet core 203 drives the clamping connecting rod 404 to move, stretching the clamping spring 405. The clamping drive column 403 on the control rod 402 is at the end of the clamping guide groove 4011. At this time, the two clamping plates 401 are in the open state. During welding, the inner weld of the pump casing is welded first. It is necessary to manually rotate the flip plate 201. Once the flip plate 201 rotates, it will cause the extrusion protrusion 501 to move and stop pressing the power-off switch 502. The power-off switch 502 can then control the displacement electromagnet 202 to de-energize and stop attracting the electromagnet core 203. Under the pull of the clamping spring 405, the clamping connecting rod 404 drives the two control rods 402 to move. The clamping drive column 403 moves together with the clamping guide groove 4011, which is opened at an angle. At this time, the two clamping plates 401 are pushed inward by the clamping drive column 403. With the help of the clamping pressure port 4012, the outer ring of the pump shell and the pump shell end plate to be welded are clamped and limited, ensuring the accuracy of the subsequent welding of the inner weld of the pump shell. Then, the inner weld of the pump shell can be welded by the laser welding head. After the inner weld is welded, the outer ring of the pump shell and the pump shell end plate have been welded and positioned. There is no need for external limiting and fixing. The flip plate 201 can be rotated and flipped again to change the face. At this time, the extrusion protrusion 501 extrudes the power-off switch 502 again. The corresponding two clamping plates 401 will expand and no longer fit to clamp the pump shell. The outer weld of the pump shell can be directly welded by the laser welding head, realizing the rapid welding of the inner and outer welds of the pump shell, which is efficient and convenient.
