Description

A self-priming pump check valve filter assembly fixture Technical Field

[0001] This utility model relates to the field of check valve filter assembly technology, specifically a tooling for assembling a check valve filter for a self-priming pump. Background Technology

[0002] Before the introduction of the self-priming pump check valve filter assembly fixture, the assembly process of the pump check valve filter relied entirely on manual operation. During manual assembly, the operator had to wrap the rubber sleeve around the filter screen and filter element assembly to complete the sealing. Since the filter screen is made of metal, it is easy to cause skin damage to workers during the assembly process, posing a safety hazard. Moreover, there is no fixed connection between the filter element assembly and the filter screen, and the operator must continuously press with their hands to prevent misalignment. This not only increases the difficulty of operation but also makes the efficiency low. The average daily output of a single person operating this process is low. The low production efficiency leads to a significant increase in manufacturing costs, making it difficult to meet the needs of large-scale production and also hindering the company's competitiveness in the market. Therefore, we have proposed a self-priming pump check valve filter assembly fixture. Summary of the Invention

[0045] Spring 5: The two ends of spring 5 are welded to the top of pressure rod 6 and support rod 16 respectively. When pressure rod 6 is pressed down, it is stretched. After assembly, the spring force pushes pressure rod 6 and control rod 4 to reset, so as to realize continuous operation.

[0046] Pressure rod 6: Pressure rod 6 is inserted into the hollow column 14. The side wall is provided with toothed opening 18 to mesh with gear block 17. When pressed down, it is inserted into tooling sleeve 7 to push the filter screen and filter element assembly to complete the assembly of the rubber sleeve.

[0047] Tooling sleeve 7: Tooling sleeve 7 is bowl-shaped and is snapped into the mating hole 12 of the rotating carrier plate 2. The bottom is provided with a rubber cup 19 and a bent bottom ring 20, which are used to pre-fix the rubber sleeve and support the filter screen and filter element assembly.

[0048] Support rod 8: The support rod 8 is vertically connected to the base 1 and the tooling assembly. The bottom shaft end is connected to the rotating carrier plate 2 to provide rotational support, and the top shaft end is fixed to the pressing assembly mechanism. It is a key structure for force transmission.

[0049] Fixing hole 9: Fixing hole 9 is opened at the bottom of base 1 and is used to pass through bolts and other fasteners to securely install base 1 on the workbench and ensure the overall stability of the tooling during assembly.

[0050] Reinforcing rib 10: Reinforcing rib 10 is provided on the side wall of the rotating cylinder 11 to enhance the load-bearing strength of the rotating load plate 2 and prevent the plate from bending and deforming due to excessive bending moment caused by the weight of the load-bearing components.

[0051] Rotating cylinder 11: The rotating cylinder 11 is located on one side of the rotating platform 2, sleeved on the support rod 8, and cooperates with the reinforcing rib 10 to provide a structural basis for the rotating platform 2 to rotate radially around the support rod 8;

[0052] Mating hole 12: The mating hole 12 is provided on the side of the rotating carrier plate 2 away from the rotating cylinder 11, and is used to engage with the tooling sleeve 7 to accurately position the tooling sleeve 7 and ensure accurate placement of the assembled parts;

[0053] Groove fixing cylinder 13: Groove fixing cylinder 13 is located on the side of the fixing component 3 and is sleeved with the support rod 8. It is fixed by the matching bolts to securely install the pressing assembly mechanism on the top of the support rod 8.

[0054] Hollow column 14: Hollow column 14 is parallel to slotted fixing cylinder 13, allowing pressure rod 6 to pass through and be guided. A drive hollow block 15 is provided on the side wall to provide space for the transmission between gear block 17 and pressure rod 6.

[0058] Toothed opening 18: Toothed opening 18 is evenly distributed on the side wall of the pressure rod 6 and meshes with the outer side of the gear block 17. Driven by the gear block 17, the pressure rod 6 makes a precise vertical lifting and lowering motion along the mating hollow column 14.

[0059] Rubber cup 19: The rubber cup 19 is located at the bottom of the tooling sleeve 7. It has an open structure design. When the pressure rod 6 pushes the component, it squeezes the rubber sleeve together with the bending bottom ring 20 to deform it and complete the assembly.

[0060] Bending bottom ring 20: The bending bottom ring 20 is located outside the rubber cup 19 and provides initial fixation for the rubber sleeve fitted on the tooling sleeve 7, so that the rubber sleeve can accurately wrap the assembly parts when the pressure rod 6 is pressed down.

[0061] Working Principle: Install the self-priming pump check valve filter assembly fixture correctly according to the diagram. The self-priming pump check valve filter assembly fixture works collaboratively with components such as the base 1, rotating carrier plate 2, and pressing assembly mechanism to achieve efficient assembly of the filter screen and filter element assembly. The support rod 8 on the side of the base 1 serves as the core support structure. Its bottom shaft end is connected to the rotating carrier plate 2, and its top shaft end is fixed to the pressing assembly mechanism. The operator first rotates the rotating carrier plate 2 around the support rod 8 to one side, using its mating hole 12 to engage the bowl-shaped fixture sleeve 7. The rubber sleeve is then placed on the outside of the fixture sleeve 7 from the bottom, and the bottom ring 20 is bent to initially fix the rubber sleeve. The filter screen and filter element assembly are then inserted sequentially from the top of the fixture sleeve 7. The carrier plate 2 is rotated to directly below the pressing assembly mechanism. At this time, the control rod 4 on the fixing part 3 rotates. The gear block 17 rotates within the drive hollow block 15, and through the meshing of the toothed opening 18 with the side wall of the pressure rod 6, the pressure rod 6 moves vertically downward within the mating hollow column 14. The bottom of the pressure rod 6 inserts into the tooling sleeve 7, pushing the filter screen and filter element assembly downward. The rubber cup 19 and the outer rubber sleeve of the bent bottom ring 20 are deformed under pressure. When the filter screen and filter element assembly are pushed out of the tooling sleeve 7, the rubber sleeve rebounds and fits perfectly on the outside of both, completing the assembly. During the pressing process, the spring 5 is stretched. After releasing the control rod 4, the spring 5 rebounds and resets the pressure rod 6 and control rod 4, facilitating the next operation. The reinforcing ribs 10 on the side wall of the rotating cylinder 11 enhance the load-bearing capacity of the rotating carrier plate 2 and prevent it from bending. The entire process replaces manual pressing with a mechanical structure, achieving fast and precise one-time molding assembly.
