Problems solved by technology

However, since the surface of the water hydraulic pump's sliding shoe is covered with a layer of wear-resistant engineering plastics, it cannot withstand too much compression force, so the sliding shoe in the water hydraulic plunger pump should not be closed in this way.

Abstract

The invention discloses an assembly tool and an assembly method for a piston shoe assembly for a water hydraulic piston pump, and belongs to the technical field of mechanical parts and processing. The assembly tool comprises a base (2), two semi-round rings (3) with different sizes, and a pressure cover (1), wherein the two semi-round rings (3) are positioned in a cylindrical groove in the base (2); the pressure cover (1) is against the semi-round rings (3); a round hole used for a piston (4) to pass through is formed in the pressure cover (1); and chamfers are arranged on the inner sides of the semi-round rings (3). The assembly method comprises the steps as follows: closing a piston shoe by the assembly tool until the required size is met, removing the allowance of a closed opening by lathing, wrapping the neck of the piston shoe (5) with a protection sleeve, clamping the piston shoe onto a lathe chuck, wrapping the middle of the piston (4) with another protection sleeve, sleeving the protection sleeve with a piston rocking tool (6), tightening and fixing screws (7) to a tool rest, and rotating a lathe for running-in. Therefore, the problem of excessively large clamping force is avoided and the tool is simple and easy to realize.

Description

technical field [0001] The invention relates to a plunger sliding shoe assembly for a hydraulic plunger pump and a processing method thereof, belonging to the technical field of mechanical parts and processing thereof. Background technique [0002] The water hydraulic pump is the core power component in the water hydraulic system. Now various countries are working hard to develop seawater and freshwater hydraulic components. The water hydraulic pumps that have been researched and developed mainly include gear type, vane type and plunger type. Due to the meshing of the line height pair of the gear pump, the contact specific power is very large, the vane pump is more sensitive to the pollution of the medium, the structure is also more complicated and the sealing effect is poor; the plunger pump has the characteristics of compact structure, light weight, high working pressure, etc., in the same Under certain working conditions, the specific work of key parts is much smaller th...
