Abstract

The invention discloses a detection device for measuring the axial micro clearance of a spherical coupling, which includes a base, a support, a gland, a slider, a mandrel rod, a pressure ring, a pressure spring and a stop screw; the spherical coupling The plunger rod of the component is fixed in the support and the gland hole. By pushing the slider to move to the right, the slider, the plunger seat of the spherical coupling, and the mandrel rod are moved to the right as a whole. The dial indicator installed on the base The axial clearance between the plunger on the spherical coupling and the ball socket in the plunger seat can be read. The invention can accurately judge the axial clearance between the plunger body of the oil pump product and the ball socket in the plunger seat, has a compact structure, low manufacturing cost, high detection efficiency, and meets the technical requirements for digital rapid measurement of the product.

Description

technical field [0001] The invention belongs to the technical field of precision parts measurement, and in particular relates to a detection device for measuring the axial micro clearance of a spherical coupling. Background technique [0002] The plunger pump is widely used in various aerospace products and engineering machinery due to its compact structure, high working pressure, high efficiency and convenient adjustment. The precision spherical coupling is formed by connecting the plunger seat and the plunger body through spherical fit. The performance such as the axial clearance after the connection has a significant impact on the working efficiency and service life of the oil pump. The connection between the plunger seat and the plunger body usually adopts mechanical closing. This technology uses external force to make the metal cold extrusion of the plunger seat mouth to cause it to undergo plastic deformation, so that it covers the spherical surface of the plunger body...
