Embodiment Construction

[0026] Such as figure 1 with figure 2 As shown, the plunger pump cylinder cup assembly device includes a fixed base plate 1, a mounting mandrel 2 vertically installed on the fixed base plate 1, and a limit bracket 3 overlaid on the bottom of the mounting mandrel. Wherein, the fixed bottom plate 1 is provided with a limit bracket cushion block 11 to support the limit bracket 3, and an installation mandrel support block 12 is provided to support the bottom of the support installation mandrel. The top of the installation mandrel 2 is provided with a cup installation groove for folding the cup into a U shape, and the radially outer side of the installation mandrel is nested with a protective sleeve 4 that can move up and down. At this time, the protective sleeve 4 is first moved up and penetrated into the inner hole of the plunger pump cylinder. At this time, the protective sleeve 4 completely wraps the cup in the cup installation groove, so as to avoid the Deformed or damaged ...

Abstract

The invention discloses a plunger pump cylinder leather cup assembly device and method. The plunger pump cylinder leather cup assembly device comprises a fixed bottom plate, an installation core rod perpendicularly installed on the fixed bottom plate, and a limiting support arranged outside the bottom of the installation core rod in a sleeving mode. A leather cup installation groove is formed in the top of the installation core rod, and a leather cup is folded into a U shape to be placed into the leather cup installation groove. The radial outer side of the installation core rod is provided with a protective sleeve capable of moving up and down in a nesting mode. The top of the limiting support is provided with a through hole, the limiting sleeve penetrates out of the through hole, and the open end of a plunger pump cylinder penetrates into the through hole. The top face of the limiting support limits steps of the open end of the plunger pump cylinder during downward pressing of the plunger pump cylinder. A movable lever pushing the leather cup into a leather cup groove of an inner hole of the plunger pump cylinder under the downward-pressing driving of the protective sleeve is arranged in the protective sleeve. Through the plunger pump cylinder leather cup assembly device and assembly method, one-time assembly in place rate of the leather cup is very high, and the edge warping and edge turning phenomena after in-place assembly of the leather cup can be avoided effectively.

Description

technical field [0001] The invention relates to auto parts technology, in particular to a piston pump cylinder body leather cup assembly device. Background technique [0002] In the prior art, the plug-type plunger pump cylinder cup assembly device has solved how to pack the cup into the plunger pump cylinder cup groove. For example, the Chinese invention patent with the publication number CN105500270A disclosed on April 20, 2016 a kind of assembly tooling and method for a plunger pump cylinder cup assembly device cup, which includes, including a guide rod, and the guide rod can Stretch into the cylinder hole of the plunger pump cylinder and can pass through the center hole of the cup; can extend into the guide sleeve in the cylinder bore of the plunger pump cylinder, the inner diameter of the guide sleeve is larger than The outer diameter of the guide rod, after the guide sleeve is sleeved on the outside of the guide rod, the gap between the guide sleeve and the guide rod ...
