Description

Technical Field

[0001] The present invention relates to the technical field of impeller welding equipment, and particularly to an impeller welding device for water pump processing and its usage method. Background Art

[0002] An impeller welding device for water pump processing is a professional equipment used to weld various components of an impeller (such as blades, hubs, etc.) together. It mainly consists of a base and a welding workbench as the basic framework. The base ensures the stability of the device, and the workbench is used to place the impeller components and carry out welding operations. The device is equipped with a clamping and positioning system. Through a radial clamping mechanism and an axial positioning component, the impeller is accurately fixed to ensure that the impeller does not displace during the welding process.

[0016] S2: Position the impeller;

[0017] S3: Filter impurities in water;

[0018] S4: Water is refluxed and reused.

[0019] The present invention has the following beneficial effects:

[0020] (1) The impeller welding device for water pump processing of the present invention first sleevs the hollow roller to be welded on the circular rod, places the impeller to be welded and spliced into the U-shaped hollow block, and starts the hydraulic cylinder. The hydraulic cylinder pushes the grooved push plate to rise. The grooved push plate pushes the water in the water storage tank upward. Under the action of its pressure, the water makes the two adaptive trapezoidal plates move away from each other. The water will enter the U-shaped hollow block through the circular box, the water inlet pipe, the annular hollow block, and the water delivery pipe. When the water pressure passes through the through hole, it will also push several sliding plates and the hollow block close to each other. The water pressure will also cause the rubber sleeve to expand, so that the corresponding two rubber sleeves clamp the impeller. Under the characteristics of the water flow and the easy deformation of the rubber sleeve, the water pressure will make the rubber sleeves evenly distribute on the impeller according to the shape of the impeller, ensuring that the impeller will not be deformed under the clamping force of the strong water pressure, ensuring the accuracy of the welding and splicing, and improving the quality of the welding and splicing;

[0021] (2) In the impeller welding device for water pump processing of the present invention, when the grooved push plate rises, it will drive several push rods to rise. When the push rods rise, they will contact the annular movable plate and drive the annular movable plate to rise. The annular movable plate will drive several connecting round rods to move simultaneously. The connecting round rods will drive several T-shaped rods to approach each other. At this time, the telescopic spring undergoes compressive deformation. When the rubber sleeve completes the clamping and fixing of the impeller, several T-shaped rods will drive several U-shaped hollow blocks to approach each other. Several U-shaped hollow blocks will also drive several impellers to abut against the hollow roller sleeved on the circular rod. The impeller abutting against the hollow roller will automatically adjust its position, enabling the impeller to be accurately positioned at the welding and splicing position on the hollow roller, ensuring the quality of the welding and splicing;

[0022] (3) In the impeller welding device for water pump processing of the present invention, after the impeller is positioned, the hydraulic cylinder is closed. At this time, since the water no longer moves, the adaptive trapezoidal plates will approach and contact each other under the elastic force of the adaptive spring. When the impeller welding and splicing is completed, the electric telescopic rod is started. The electric telescopic rod drives the connecting plate to rise. The connecting plate drives the L-shaped arc plate to rise. After the L-shaped arc plate leaves the annular hollow block and the water outlet pipe opening, the water will flow from the U-shaped hollow block, the water delivery pipe, the annular hollow block, and the water outlet pipe into the rectangular box. At this time, the filter drawer in the rectangular box will filter the water, filtering the impurities in the water into the filter drawer, avoiding the impurities in the water from wearing the rubber sleeve and affecting the service life of the rubber sleeve;

[0023] (4) In the impeller welding device for water pump processing of the present invention, the filtered water will flow back to the water storage tank through the return pipe. Then the hydraulic cylinder is started. The hydraulic cylinder drives the grooved push plate to descend. At this time, when the grooved push plate contacts the water below the grooved push plate, the water will pass through the water through hole. Under the action of the water pressure, the rectangular plate will rise. The rectangular plate drives the L-shaped movable plate to rise. At this time, the movable spring undergoes tensile deformation. The water passing through the water through hole will flow from the gap between the rectangular plate and the grooved push plate to the upper part of the grooved push plate, preparing for the next clamping and positioning.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] like Figure 6 As shown, an adaption mechanism 7 is provided on the water tank 510, and the adaption mechanism 7 includes a strip groove 701 opened on the water tank 510, and adaption springs 702 are fixedly installed on the left inner wall and the right inner wall of the strip groove 701, respectively, and adaption trapezoidal plates 703 are fixedly installed on the ends of the two adaption springs 702 close to each other, and the two sides of the two adaption trapezoidal plates 703 close to each other are in contact.

[0048] After the impeller is positioned, the hydraulic cylinder 607 is closed. At this time, since the water no longer moves, the adaptive trapezoidal plates 703 will approach and contact each other under the elastic force of the adaptive spring 702.

[0049] like Figure 6As shown, a circular groove 704 is provided on the top of the water tank 510, and the circular groove 704 runs through the strip groove 701.

[0051] like Figure 1 - Figure 8 As shown, the method for welding the impeller for water pump processing, the method steps are as follows:

[0053] S2: Position the impeller;

[0054] S3: Filter impurities in water;

[0055] S4: Water is refluxed and reused.

[0056] First, slip the hollow wheel roller to be welded onto the circular rod 706. Place the impeller to be butt-welded into the U-shaped hollow block 4, and start the hydraulic cylinder 607. The hydraulic cylinder 607 pushes the grooved push plate 608 upward. The grooved push plate 608 pushes the water in the water storage tank 510 upward. Under the action of its pressure, the water causes the two adaptive trapezoidal plates 703 to move away from each other. The water will enter the U-shaped hollow block 4 through the circular tank 705, the water inlet pipe 508, the annular hollow block 507, and the water delivery pipe 506. When the water pressure passes through the through hole 504, it will also push several sliding plates 501 and the hollow block 503 closer to each other. The water pressure will also cause the rubber sleeve 505 to expand, so that the corresponding two rubber sleeves 505 clamp the impeller. Due to the characteristics of the water flow and the easy deformation of the rubber sleeve 505, the water pressure will cause the rubber sleeve 505 to be evenly distributed on the impeller according to the shape of the impeller, ensuring that the impeller will not be deformed under the clamping force of the strong water pressure, ensuring the accuracy of the butt welding and improving the quality of the butt welding; During the upward movement of the grooved push plate 608, it will drive several push rods 707 upward. During the upward movement of the push rods 707, they will contact the annular movable plate 708 and drive the annular movable plate 708 upward. The annular movable plate 708 will drive several connecting round rods 709 to move simultaneously. The connecting round rods 709 will drive several T-shaped rods 2 closer to each other. At this time, the telescopic spring 3 undergoes compressive deformation. When the rubber sleeve 505 completes the clamping and fixing of the impeller, several T-shaped rods 2 will drive several U-shaped hollow blocks 4 closer to each other. Several U-shaped hollow blocks 4 will also drive several impellers to abut against the hollow wheel roller sleeved on the circular rod 706. The impellers abutting against the hollow wheel roller will automatically adjust their positions, enabling the impellers to be accurately positioned at the butt-welding positions on the hollow wheel roller, ensuring the quality of the butt welding;

[0057] After the impeller is positioned, the hydraulic cylinder 607 is closed. At this time, since the water no longer moves, the adaptive trapezoidal plates 703 will approach and contact each other under the elastic force of the adaptive spring 702. When the impeller is welded, the electric telescopic rod 605 is started, and the electric telescopic rod 605 drives the connecting plate 603 to rise, and the connecting plate 603 drives the L-shaped arc plate 601 to rise. After the L-shaped arc plate 601 leaves the annular hollow block 507 and the outlet pipe 509, water will flow from the L-shaped hollow block 4 and the water pipe 506 as well as the annular hollow block 507 and the outlet pipe 509 into the rectangular box 511. At this time, the filter drawer 512 in the rectangular box 511 will filter the water and filter the impurities in the water into the filter drawer 512, avoiding Impurities in the water are prevented from causing wear to the rubber sleeve 505 and affecting the service life of the rubber sleeve 505; the filtered water will flow into the water storage tank 510 through the return pipe 513, and then the hydraulic cylinder 607 will be started, and the hydraulic cylinder 607 will drive the grooved push plate 608 to descend. At this time, when the grooved push plate 608 contacts the water below the grooved push plate 608, the water will pass through the water hole 609, and the rectangular plate 610 will rise under the action of water pressure, and the rectangular plate 610 will drive the L-shaped movable plate 611 to rise. At this time, the movable spring 612 will be stretched and deformed, and the water passing through the water hole 609 will flow from the gap between the rectangular plate 610 and the grooved push plate 608 to the top of the grooved push plate 608, preparing for the next clamping and positioning.
