An adaptive anti-resonance fixture along the inner side of the submersible pump shell

Abstract

The invention discloses an adaptive anti-resonance fixing fixture along the inner side of a submersible pump shell, which includes a dynamically adjustable rotating resistance increasing device, a connecting rod turning-type upper and lower limit device, an anti-resonance filling resistance increasing structure, a horizontal rotation device, a space Fold unit and place table. The invention belongs to the technical field of submersible pump processing equipment, and specifically refers to an adaptive anti-resonance fixing fixture along the inner side of the submersible pump casing; the invention creatively combines the dynamic characteristic principle with an adaptive adjustment device, so that the fixing fixture can be reduced The volume moves along the inlet and outlet ends of the submersible pump casing, and can be extended outward to achieve a large area of ​​contact with the casing, while avoiding the misunderstanding that the fixing fixture must be fixed from the outside, and does not affect the external processing of the casing; The combination of spring, porous sponge and metal foam realizes the basic functions of shock absorption, noise reduction and self-adaptive unstable shell edge, avoiding the harm caused by the resonance between the processing equipment and the fixed fixture during the processing.

Description

technical field [0001] The invention belongs to the technical field of submersible pump processing equipment, and specifically refers to an adaptive anti-resonance fixing fixture along the inner side of a submersible pump casing. Background technique [0002] Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water to extract groundwater to the surface, which can be used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, ship loading, and fountain landscape. [0003] During the production of the shell of the submersible pump, due to the problem of making molds, there will be metal protrusions or metal burrs on the surface of the shell. These burrs need to be polished to meet the assembly standards of the submersible pump. Both fix the casing on a platform, and fix the submersible pump casing by squeezing the outside of the submersible pump casing. However, when the ca...

Problems solved by technology

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an adaptive anti-resonance fixing fixture along the inner side of the submersible pump casing. In order to realize the reduction in volume and convenient movement, it can also extend outward to increase contact with the submersible pump casing. The large-area fixed fixture that moves along the inner wall combines the principle of dynamic characteristics with the self-adaptive adjustment device. The characteristics of the rotation angle of the folding plate can be adjusted by turning the folding structure and the horizontal rotation extension structure can adjust the characteristics of the extension diameter in the horizontal direction. The fixing fixture can automatically adapt to a variety of submersible pump shells with different diameters, overcome the cognitive misunderstanding that the fixing fixture must be fixed from the outside, and solve the problem that the traditional water pump fixing fixture will occupy part of the pump casing when it is fixed. The inner wall of the fixed shell is used to fix the submersible pump shell; in order to avoid resonance between the grinding processing equipment and the fixing fixture, and to effectively fix the defective and uneven submersible pump shell, the porous sponge plate is used to wrap the shock absorber At the bottom of the spring, the foam metal plate that is more difficult to be damaged by friction is used to replace the traditional sponge plate, and the foam metal is connected to the shock-absorbing spring, which can effectively squeeze and fix the shell while avoiding equipment resonance during the grinding process. It effectively solves the problems of low efficiency, complex structure and inconvenient maintenance of the existing submersible pump housing fixing fixtures on the market
