Technical Field

The invention relates to a device for detecting the axial height of types of plunger pumps after cylinder bodies and valve plates are ground, belonging to the technical field of plunger pump detection tools.

Background

is applied to the hydraulic field of the axial plunger pump, the plunger reciprocates under the rotation of the cylinder body to realize the change of the volume and complete the actions of sucking, discharging oil and the like, wherein the axial height of the cylinder body after the cylinder body and the port plate are ground is related to the pre-compression force of the spherical hinge spring, and the pre-compression force can influence the normal operation of the plunger pump, so the problems of jamming, large internal leakage and the like occur, therefore, the measurement of the axial height of the cylinder body and the port plate of the axial plunger pump after being ground is very important and necessary.

Disclosure of Invention

The invention aims to solve the technical problem that the axial height cannot be accurately and quickly measured by the conventional tool for measuring the axial height of a cylinder body and a valve plate of an axial plunger pump after being lapped, and provides an -type detection device for the axial height of the cylinder body and the valve plate of the plunger pump after being lapped.

In order to solve the technical problems, the invention adopts the technical scheme that:

A device for detecting the axial height of a cylinder body and a valve plate of a plunger pump after lapping comprises a detection workbench, a measuring rod, a connecting sleeve, a detection rod, a copper gasket, an installation support, a circumferential positioning sleeve, an adjusting screw, an installation screw, a positioning screw and a positioning pin, wherein the measuring rod is vertically fixed at the angle of the detection workbench through the installation screw, the installation support is fixedly arranged on the table top of the detection workbench through the positioning pin, the lower part of the circumferential positioning sleeve is arranged in a round hole arranged at the center of the installation support, the copper gasket is arranged on the inner side of the connecting sleeve, the connecting sleeve is arranged on the measuring rod through the positioning screw, the end of the detection rod is sleeved on the outer side of the connecting sleeve and is fixed on the connecting sleeve through the adjusting screw, the other end of the detection rod is provided with a mandrel, and the mandrel is matched with the round hole arranged at the center of the circumferential positioning sleeve.

The invention has the beneficial effects that:

1. the mounting bracket and the circumferential positioning sleeve arranged on the detection workbench can quickly position the matched position of the cylinder body and the valve plate, so that the detection speed is improved;

2. the spindle is designed at the end of the detection rod and is matched with the circumferential positioning sleeve, so that the detection precision can be improved.

3. The axial height of the cylinder body and the valve plate after being lapped can be directly read by sliding the detection rod up and down and matching with the measuring rod with scales, so that the pre-pressing force of the spherical hinge spring can be quickly determined.
