[0002] The water pump impeller is made of cast iron. The blades on the water pump impeller play a major role. The shape and size of the water pump impeller are closely related to the performance of the water pump. Water pump impellers can generally be divided into single-suction type and double-suction type. The single-suction impeller sucks water from one side, and most of the small-flow water pump impellers are of this type. The double-suction impeller sucks water from both sides, and all large-flow water pump impellers adopt double-suction impellers.

[0003] And when the pump impeller is currently being produced and processed, it is necessary to weld between the impeller and the pump body. Generally, when the general pump impeller welding device welds the pump impeller, it cannot clamp the outer wall of the pump impeller in real time according to the situation. When the size of the pump impeller changes, the clamping structure needs to be replaced or the welding device needs to be replaced, which is time-consuming and laborious and increases the economic cost of the pump impeller. This phenomenon has become a problem that needs to be solved urgently by the personnel in this field. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Please refer to Figure 1-6As shown in the figure, a welding device for machining a large-flow pump impeller includes a workbench 6. A bottom plate 5 is installed on the outer wall of the workbench 6. A connecting rod 4 is arranged on the top of the bottom plate 5. A support 1 is connected to the outer wall of the connecting rod 4. A hydraulic rod 7 is installed at the bottom of the support 1. One end of the hydraulic rod 7 is connected to a welding device main body 8;

[0027] A cavity 10 is formed on the top of the workbench 6. A protective cover 12 is installed on the outer wall of the workbench 6. A motor 11 is arranged inside the protective cover 12. The output shaft of the motor 11 is movably connected to a lead screw 20 through a coupling. One end of the lead screw 20 penetrates through the outer wall of the workbench 6 and extends into the cavity 10. The other end of the lead screw 20 is connected to the inner wall of the workbench 6. A sliding block 22 is installed on the outer wall of the lead screw 20. A sliding plate 13 is installed on the top of the sliding block 22. A connecting groove 14 is formed on the inner wall of the sliding plate 13. An anti-slip plate 16 is arranged inside the connecting groove 14.

[0028] During work, place the pump impeller to be welded on the welding table 23. According to the size of the pump impeller, start the motor 11. The motor 11 drives the lead screw 20 to drive the sliding block 22 to slide, so that the two sliding plates 13 on both sides can slide towards the middle. Fit the anti-slip plates 16 on both sides to the outer wall of the pump impeller, and move the moving plate 18 towards the middle through the moving groove 24 and the moving block 25, so that the anti-sliding blocks 19 on both sides are attached to both sides of the pump impeller to fix the position of the pump impeller. Then move the support 1 downward, and then drive the hydraulic rod 7 to adjust the welding device main body 8 downward, and use the welding device main body 8 to weld the surface of the pump impeller, thus completing the work.

[0029] In this embodiment, a fitting plate 17 is installed on the outer wall of the workbench 6. A moving block 25 is installed on the top of the fitting plate 17. The outer wall of the moving block 25 is connected to a moving plate 18. An anti-sliding block 19 is installed at one end of the moving plate 18. Anti-sliding blocks 19 are arranged on both sides of the workbench 6, and the anti-sliding blocks 19 can be attached to the outer wall of the pump impeller to stabilize the position of the pump impeller.

[0030] In this embodiment, a moving groove 24 that is identical in shape and size to the moving block 25 is formed at the bottom of the moving plate 18, and the moving plate 18 is slidably connected to the fitting plate 17 through the moving groove 24 and the moving block 25. The position of the anti-sliding block 19 can be moved through the provided moving groove 24 and moving block 25, and real-time adjustment can be made according to the size of the pump impeller.

[0031] In this embodiment, both the anti-slip plate 16 and the anti-slip block 19 are arc-shaped anti-slip plates and arc-shaped anti-slip blocks. There are two anti-slip plates 16 and two anti-slip blocks 19, and the two anti-slip plates 16 and the two anti-slip blocks 19 are respectively distributed around the workbench 6. By arranging the two anti-slip plates 16 and the two anti-slip blocks 19, the periphery of the pump impeller can be clamped, avoiding the phenomenon that the position of the pump impeller slides during the welding operation, which may lead to inaccurate welding of the pump impeller.

[0032] In this embodiment, the shape and size of the connecting groove 14 and the connecting plate 15 match each other. The anti-slip plate 16 is snap-connected to the sliding plate 13 through the connecting groove 14 and the connecting plate 15. Both the anti-slip plate 16 and the anti-slip block 19 are made of rubber. By arranging the connecting groove 14 and the connecting plate 15, the position of the anti-slip plate 16 can be disassembled. After the anti-slip plate 16 has been used for a long time, it can be disassembled and replaced, which is convenient for the staff to use.

[0033] In this embodiment, a groove is formed at the top of the workbench 6, and a welding table 23 is installed inside the groove. The welding table 23 is located at the center of the workbench 6. By arranging the groove, it is convenient to remove the welding table 23 from the top of the workbench 6 and clean the welding waste inside the welding table 23.

[0034] In this embodiment, a sliding groove 9 is formed at the top of the workbench 6, and a slider 21 is arranged inside the sliding groove 9. The top of the slider 21 is connected to the bottom of the sliding plate 13. By arranging the sliding plate 13, the slider 21 at the bottom can move inside the sliding groove 9, enabling the sliding plate 13 to move synchronously using the slider 21 while moving on both sides through the lead screw 20, which plays a role in stabilizing the movement of the sliding plate 13.

[0035] In this embodiment, a sliding rod 2 is installed at the top of the bottom plate 5. There are four sliding rods 2, and sliding frames 3 are installed on the outer walls of the four sliding rods 2. The inner wall of the sliding frame 3 is connected to the outer wall of the bracket 1. By arranging the four sliding rods 2 on the outer wall of the connecting rod 4 respectively, during the up and down movement of the bracket 1, the sliding frame 3 can move up and down on the outer walls of the four sliding rods 2, which plays a role in stabilizing the movement of the bracket 1.

[0036] In summary, for the welding device for machining the impeller of a large-flow pump, when the impeller of the pump needs to be machined, move the two anti-slip plates 16 and the two anti-slip blocks 19, and attach the two anti-slip plates 16 and the two anti-slip blocks 19 to the outer wall of the pump impeller. Moreover, the position of the surrounding clamping structure can be adjusted according to the diameter of the pump impeller. This solves the problem that when the welding device for the pump impeller welds the pump impeller, it cannot clamp the outer wall of the pump impeller in real time according to the situation. When the size of the pump impeller changes, the clamping structure needs to be replaced or the welding device needs to be replaced, which is time-consuming and laborious and increases the economic cost of the pump impeller, and improves the efficiency of the welding device for machining the impeller of the large-flow pump.
