Description

Technical Field

[0001] This invention relates to the field of impeller welding equipment technology, specifically to an impeller welding device for water pump processing and its usage method. Background Technology

[0002] The impeller welding device for water pump processing is a specialized piece of equipment used to weld the various components of an impeller (such as blades and hubs) together. It mainly consists of a base and a welding worktable as its basic structure. The base ensures the stability of the device, while the worktable is used to place the impeller components and carry out welding operations. The device is equipped with a clamping and positioning system, which precisely fixes the impeller through a radial clamping mechanism and an axial positioning component, ensuring that the impeller will not shift during the welding process.

[0003] During the clamping and positioning of the impeller, most clamping devices use relatively hard metal for clamping and fixing. If the clamping force is too large, it will affect the torsion of the impeller, causing it to deform and affecting the normal use of the impeller. If the clamping force is too small, it cannot be effectively positioned, causing the impeller to shift during the welding process and affecting the accuracy of the welding. Summary of the Invention

[0004] The purpose of this invention is to provide a pump impeller welding device and its usage method, in order to solve the problem that most clamping devices use hard metal for clamping and fixing during the clamping and positioning process of the impeller. If the clamping force is too large, it will affect the torsion of the impeller, causing it to deform and affecting the normal use of the impeller. If the clamping force is too small, it cannot be effectively positioned, resulting in the impeller shifting during the welding process and affecting the welding accuracy.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] This invention relates to a welding device for impellers used in water pump processing, comprising an annular plate, on which a plurality of T-shaped rods are slidably mounted, each T-shaped rod penetrating the annular plate.

A U-shaped hollow block is fixedly mounted on the ends of the T-shaped rods closest to each other. The device also includes:

[0007] Several clamping mechanisms are provided, each including two sliding plates slidably installed inside a hollow C-shaped block.

The bottom of each L-shaped arc plate extends into the annular hollow block and blocks the opening between the water outlet pipe and the annular hollow block. Closing springs are fixedly installed on the top inner walls of each L-shaped arc plate. The bottom ends of each closing spring are fixedly connected to the annular hollow block. Connecting plates are fixedly installed between each L-shaped arc plate. An mounting plate is fixedly installed on the outer wall of the annular plate. An electric telescopic rod is fixedly installed at the bottom of the mounting plate. The output shaft of the electric telescopic rod is fixedly connected to the connecting plate.

[0010] Furthermore, a mounting bracket is fixedly installed at the bottom of the water storage tank, and a hydraulic cylinder is fixedly installed on the top inner wall of the mounting bracket. The output shaft of the hydraulic cylinder extends into the water storage tank and is slidably connected to the water storage tank. A grooved push plate is fixedly installed on the output shaft of the hydraulic cylinder, and the grooved push plate is slidably connected to the water storage tank.

[0011] Furthermore, a plurality of water passage holes are provided on the bottom inner wall of the grooved push plate, a rectangular plate is slidably installed on the grooved push plate, and two L-shaped movable plates are fixedly installed on the bottom of the rectangular plate. Both L-shaped movable plates pass through the grooved push plate and are slidably connected to the grooved push plate. Movable springs are fixedly installed on the bottom inner walls of the two L-shaped movable plates, and the top ends of the two movable springs are fixedly connected to the grooved push plate.

[0012] Furthermore, the water storage tank is provided with an adaptation mechanism, which includes a strip groove formed on the water storage tank. Adaptation springs are fixedly installed on the left and right inner walls of the strip groove, and adaptation trapezoidal plates are fixedly installed on the ends of the two adaptation springs that are close to each other. The two adaptation trapezoidal plates are in contact on the sides that are close to each other.

[0013] Furthermore, the top of the water storage tank is provided with a circular groove, which passes through the strip groove. A circular box is fixedly installed on the top of the water storage tank, and a circular rod is fixedly installed on the top of the circular box. The circular box is connected to several water inlet pipes. Several push rods are fixedly installed on the top of the grooved push plate. The top ends of the push rods extend to the outside of the water storage tank and are slidably connected to the water storage tank. An annular movable plate is provided above the annular plate. Several connecting circular rods are hinged to the outer wall of the annular movable plate. The ends of the connecting circular rods are respectively hinged to several T-shaped rods.

[0014] Furthermore, the method for welding the impeller for processing the water pump includes the following steps:

[0015] S1: Clamp and fix the impeller;

[0016] S2: Position the impeller;

[0017] S3: Filters impurities from water;

[0018] S4: Water is recycled 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 puts the hollow wheel roller to be welded on the circular rod, puts the impeller to be welded into the C-shaped hollow block, and starts the hydraulic cylinder. The hydraulic cylinder pushes the grooved push plate to rise, and the grooved push plate pushes the water in the water storage tank upward. Under its pressure, the water will move the two adaptive trapezoidal plates away from each other. The water will enter the C-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 hollow blocks to move closer 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 water flow and rubber sleeve easy deformation, the water pressure will make the rubber sleeve 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 strong water pressure, ensuring the accuracy of welding and improving the quality of welding.

[0021] (2) In the impeller welding device for water pump processing of the present invention, during the process of the grooved push plate rising, it will drive several push rods to rise. During the process of rising, the push rods 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 at the same time. The connecting round rods will drive several T-shaped rods to approach each other. At this time, the telescopic spring will be compressed and deformed. When the rubber sleeve clamps and fixes the impeller, the several T-shaped rods will drive several C-shaped hollow blocks to approach each other. The several C-shaped hollow blocks will also drive several impellers to hit the hollow wheel roller sleeved on the round rod. The impellers hitting the hollow wheel roller will automatically adjust their positions so that the impellers can be accurately positioned at the welding position on the hollow wheel roller, ensuring the quality of welding.

[0022] (3) 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 adapting trapezoidal plates will approach and contact each other under the elastic force of the adapting spring. After the impeller welding is completed, the electric telescopic rod is started. The electric telescopic rod drives the connecting plate to rise, and the connecting plate drives the L-shaped arc plate to rise. After the L-shaped arc plate leaves the annular hollow block and the outlet pipe, the water will flow from the C-shaped hollow block and the water supply pipe, as well as the annular hollow block and the outlet pipe, into the rectangular box. At this time, the filter tray in the rectangular box will filter the water and filter the impurities in the water into the filter tray to avoid the impurities in the water from causing wear on 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 into the water storage tank through the return pipe, and then the hydraulic cylinder will be started. The hydraulic cylinder will drive the grooved push plate to descend. At this time, when the grooved push plate comes into contact with the water below the grooved push plate, the water will pass through the water passage hole. Under the action of water pressure, the rectangular plate will rise. The rectangular plate will drive the L-shaped movable plate to rise. At this time, the movable spring will be stretched and deformed. The water passing through the water passage hole will go from the gap between the rectangular plate and the grooved push plate to the top of the grooved push plate, preparing for the next clamping and positioning.

[0024] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A U-shaped hollow block 4 is fixedly mounted on the ends of the T-shaped rods 2 that are close together. The device also includes:

[0038] Several clamping mechanisms 5 are provided. Each clamping mechanism 5 includes two sliding plates 501 slidably installed inside a hollow block 4. Clamping springs 502 are fixedly installed on the opposite sides of the two sliding plates 501. The opposite ends of the two clamping springs 502 are fixedly connected to the hollow block 4. Hollow blocks 503 are fixedly installed on the opposite sides of the two sliding plates 501. The opposite sides of the two hollow blocks 503 extend to the outside of the hollow block 4 and are slidably connected to the hollow block 4. Several through holes 504 are provided on the two sliding plates 501. The through holes 504 extend into the two hollow blocks 503. Rubber sleeves 505 are fixedly installed on the opposite sides of the two hollow blocks 503. A water pipe 506 is fixedly installed at the bottom of the hollow block 4.

[0039] like Figure 2 As shown, an annular hollow block 507 is fixedly installed on the outer wall of the annular plate 1. The ends of several water supply pipes 506 are fixedly connected to the annular hollow block 507. Several water inlet pipes 508 are fixedly installed on the inner wall of the annular hollow block 507. Two water outlet pipes 509 are fixedly installed on the outer wall of the annular hollow block 507. A water storage tank 510 is fixedly installed at the bottom of the annular hollow block 507. Rectangular boxes 511 are fixedly installed on the left and right sides of the water storage tank 510, respectively. The bottom ends of the two water outlet pipes 509 are fixedly connected to the two rectangular boxes 511, respectively. Filter trays 512 are slidably installed inside the two rectangular boxes 511, respectively. Return pipes 513 are fixedly installed at the bottom of the two rectangular boxes 511, respectively. The bottom ends of the two return pipes 513 are connected to the water storage tank 510.

[0040] The filter tray 512 inside the rectangular box 511 filters the water, filtering out impurities in the water and preventing them from causing wear on the rubber sleeve 505 and affecting its service life.

[0041] like Figure 3 and Figure 5 As shown, a closing mechanism 6 is provided on the annular hollow block 507. The closing mechanism 6 includes several L-shaped arc plates 601 that are slidably installed on the annular hollow block 507. The bottom of each L-shaped arc plate 601 extends into the annular hollow block 507 and blocks the opening between the water outlet pipe 509 and the annular hollow block 507. A closing spring 602 is fixedly installed on the inner top wall of each L-shaped arc plate 601. The bottom end of each closing spring 602 is fixedly connected to the annular hollow block 507. A connecting plate 603 is fixedly installed between each L-shaped arc plate 601. An installation plate 604 is fixedly installed on the outer wall of the annular plate 1. An electric telescopic rod 605 is fixedly installed at the bottom of the installation plate 604. The output shaft of the electric telescopic rod 605 is fixedly connected to the connecting plate 603.

[0042] The connecting plate 603 drives the L-shaped arc plate 601 to rise. After the L-shaped arc plate 601 leaves the opening between the annular hollow block 507 and the water outlet pipe 509, water will flow from the U-shaped hollow block 4 and the water supply pipe 506, as well as the annular hollow block 507 and the water outlet pipe 509, into the rectangular box 511.

[0043] like Figure 7 As shown, a mounting bracket 606 is fixedly installed at the bottom of the water storage tank 510, and a hydraulic cylinder 607 is fixedly installed on the top inner wall of the mounting bracket 606. The output shaft of the hydraulic cylinder 607 extends into the water storage tank 510 and is slidably connected to the water storage tank 510. A grooved push plate 608 is fixedly installed on the output shaft of the hydraulic cylinder 607 and is slidably connected to the water storage tank 510.

[0044] Then, the hydraulic cylinder 607 is activated, which drives the grooved push plate 608 to descend. When the grooved push plate 608 comes into contact with the water below it, the water will pass through the water passage hole 609.

[0045] like Figure 7 As shown, a number of water passage holes 609 are provided on the bottom inner wall of the grooved push plate 608. A rectangular plate 610 is slidably installed on the grooved push plate 608. Two L-shaped movable plates 611 are fixedly installed on the bottom of the rectangular plate 610. Both L-shaped movable plates 611 pass through the grooved push plate 608 and are slidably connected to the grooved push plate 608. Movable springs 612 are fixedly installed on the bottom inner walls of the two L-shaped movable plates 611 respectively. The tops of the two movable springs 612 are fixedly connected to the grooved push plate 608.

[0046] Under the action of water pressure, the rectangular plate 610 will rise, 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 go 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.

[0047] like Figure 6 As shown, the water storage tank 510 is provided with an adaptation mechanism 7. The adaptation mechanism 7 includes a strip groove 701 opened on the water storage tank 510. Adaptation springs 702 are fixedly installed on the left inner wall and the right inner wall of the strip groove 701, respectively. Adaptation trapezoidal plates 703 are fixedly installed on the ends of the two adaptation springs 702 that are close to each other, and the sides of the two adaptation trapezoidal plates 703 that are 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 adapting trapezoidal plates 703 will approach and contact each other under the elastic force of the adapting spring 702.

[0049] like Figure 6As shown, a circular groove 704 is provided on the top of the water storage tank 510, and the circular groove 704 passes through the strip groove 701. A circular box 705 is fixedly installed on the top of the water storage tank 510, and a circular rod 706 is fixedly installed on the top of the circular box 705. The circular box 705 is connected to several water inlet pipes 508. Several push rods 707 are fixedly installed on the top of the grooved push plate 608. The top ends of the push rods 707 extend to the outside of the water storage tank 510 and are slidably connected to the water storage tank 510. An annular movable plate 708 is provided above the annular plate 1. Several connecting round rods 709 are hinged to the outer wall of the annular movable plate 708. The ends of the connecting round rods 709 are respectively hinged to several T-shaped rods 2.

[0050] During the upward movement of the grooved push plate 608, several push rods 707 will be driven to rise. During the upward movement, the push rods 707 will contact the annular movable plate 708 and drive the annular movable plate 708 to rise. 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 to move closer to each other.

[0051] like Figure 1 - Figure 8 As shown, the method for welding impellers for water pump processing includes the following steps:

[0052] S1: Clamp and fix the impeller;

[0053] S2: Position the impeller;

[0054] S3: Filters impurities from water;

[0055] S4: Water is recycled and reused.

[0056] First, the hollow roller to be welded is fitted onto the circular rod 706. Then, the impeller to be welded is placed inside the U-shaped hollow block 4, and the hydraulic cylinder 607 is activated. The hydraulic cylinder 607 pushes the grooved push plate 608 upward, which in turn pushes the water in the water tank 510 upward. Under its pressure, the water pushes the two adaptive trapezoidal plates 703 away from each other. The water then enters the U-shaped hollow block 4 through the circular box 705, the 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 also pushes several sliding plates 501 and hollow blocks 503 closer together. The water pressure also causes the rubber sleeves 505 to expand, clamping the impeller between the corresponding two rubber sleeves 505. Due to the water flow and the easily deformable nature of the rubber sleeves 505, the water pressure causes the rubber sleeves 505 to be evenly distributed on the impeller according to its shape, ensuring that the impeller is clamped by the strong water pressure. The force will not cause the impeller to deform, ensuring the accuracy of the welding and improving the quality of the welding. During the upward movement of the grooved push plate 608, it will drive several push rods 707 to rise. During the upward movement, the push rods 707 will contact the annular movable plate 708 and drive the annular movable plate 708 to rise. 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 to move closer to each other. At this time, the telescopic spring 3 will be compressed and deformed. When the rubber sleeve 505 clamps and fixes the impeller, the several T-shaped rods 2 will drive several C-shaped hollow blocks 4 to move closer to each other. The several C-shaped hollow blocks 4 will also drive several impellers to push against the hollow rollers sleeved on the round rods 706. The impellers that push against the hollow rollers will automatically adjust their positions so that the impellers can be accurately positioned at the welding position on the hollow rollers, ensuring the quality of the welding.

[0057] After the impeller is positioned, the hydraulic cylinder 607 is closed. Since the water no longer moves, the trapezoidal plates 703 will approach and contact each other under the elastic force of the adapting spring 702. After the impeller welding is completed, the electric telescopic rod 605 is activated. The electric telescopic rod 605 drives the connecting plate 603 to rise, which in turn drives the L-shaped arc plate 601 to rise. After the L-shaped arc plate 601 leaves the opening between the annular hollow block 507 and the water outlet pipe 509, water will flow from the U-shaped hollow block 4, the water supply pipe 506, the annular hollow block 507, and the water outlet pipe 509 into the rectangular box 511. At this time, the filter tray 512 inside the rectangular box 511 will filter the water, filtering impurities into the filter tray 512 to prevent... Impurities in the water prevent wear on the rubber sleeve 505, thus affecting its service life. The filtered water flows into the water storage tank 510 through the return pipe 513. Then, the hydraulic cylinder 607 is activated, which drives the grooved push plate 608 to descend. When the grooved push plate 608 comes into contact with the water below it, the water passes through the water passage hole 609. Under the action of water pressure, the rectangular plate 610 rises, which in turn drives the L-shaped movable plate 611 to rise. At this time, the movable spring 612 is stretched and deformed. The water passing through the water passage 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.
