Abstract

The invention relates to a device for detecting axial height of types of plunger pumps after cylinder bodies and valve plates of the plunger pumps are ground, which belongs to the technical field of plunger pump detection tools and aims to solve the technical problem that the axial height cannot be accurately and quickly measured by the existing measurement tools.

Description

Axial height detection device for kinds of plunger pump after cylinder and valve plate are ground
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.

FIG. 2 is an isometric view of the present invention;
FIG. 3 is a schematic view of the measurement operation of the present invention;
in the figure: 1-detection workbench, 2-measuring rod, 3-connecting sleeve, 4-detection rod, 5-copper gasket, 6-mounting bracket, 7-circumferential positioning sleeve, 8-adjusting screw, 9-mounting screw, 10-positioning screw, 11-positioning pin, 12-valve plate and 13-cylinder body.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1 and 2, the device for detecting the axial height of types of plunger pumps after lapping a cylinder body and a port plate in the embodiment comprises a detection workbench 1, a measurement rod 2, a connecting sleeve 3, a detection rod 4, a copper gasket 5, a mounting bracket 6, a circumferential positioning sleeve 7, an adjusting screw 8, a mounting screw 9, a positioning screw 10 and a positioning pin 11, wherein the measurement rod 2 is vertically fixed at an angle of the detection workbench 1 through the mounting screw 9, the mounting bracket 6 is fixedly arranged on a table top of the detection workbench 1 through the positioning pin 11, the lower part of the circumferential positioning sleeve 7 is arranged in a circular hole arranged at the center of the mounting bracket 6, the copper gasket 5 is arranged at the inner side of the connecting sleeve 3, the connecting sleeve 3 is arranged on the measurement rod 2 through the positioning screw 10 and can slide up and down, the end of the detection rod 4 is sleeved at the outer side of the connecting sleeve 3 and is fixed on the connecting sleeve 3 through the adjusting screw 8, and the other end of the detection rod 4 is provided with a mandrel matched with the circular hole arranged at the center of the circumferential positioning sleeve 7.
The working process of the invention is as follows:
as shown in figure 3, when the plunger pump is used, the cylinder body 13 is installed on the installation support 6, the valve plate 12 is matched with the cylinder body, the adjusting screw 8 is screwed after the spindle of the detection rod 4 is positioned on the valve plate 12, so that the axial height of the cylinder body after the valve plate and the valve plate are matched can be accurately read on the measurement rod 2, and the pre-pressing force of the ball hinge spring is rapidly calculated through calculation, so that the plunger pump is ensured to run more stably and have longer service life.
