Abstract

The invention discloses a servo valve pneumatic match grinding table. The servo valve pneumatic match grinding table comprises an air source, wherein the air source is connected in series with an air filter, a three unit used for reducing pressure and a main switch in sequence; the main switch is connected in series with a first air inflow switch and a second air inflow switch which are connected in parallel with each other; the first air inflow switch and the second air inflow switch are respectively connected with a first air inlet and a second air inlet which are formed in a tool body outside a valve core and a valve sleeve; a first air outlet, a second air outlet and an air outlet on the tool body are respectively connected with a first air outflow switch, a second air outflow switch and a switch which are connected in parallel with one another; a small flow meter, a medium flow meter and a large flow meter are respectively connected in series with switches and connected in parallel with one another; one end of a parallel-connection network is connected in series with the first air outlet switch, the second air outlet switch and the switch which are connected in parallel with one another. The invention provides a measuring tool capable of meeting the requirement on axial match grinding precision. The servo valve pneumatic match grinding table is simple, easy and clean and has high precision, and the small-amount production of servo valves can be realized.

Description

technical field [0001] The invention relates to a servo valve pneumatic grinding table. Background technique [0002] The spool and valve sleeve coverage matching grinding of the electro-hydraulic servo valve, that is, the axial matching grinding, is an important process in the manufacture of the servo valve. Axial matching grinding is the manufacturing process with the highest precision requirements except radial matching grinding, and its coverage requirement is generally only 1-3 μm, and it is difficult to meet the above precision requirements with general mechanical measurement. Contents of the invention [0003] The purpose of the present invention is to provide a measuring tool capable of meeting the requirement of axial grinding precision. [0004] In order to achieve the above object, the technical solution of the present invention is to provide a servo valve pneumatic grinding table, including an air source, which is connected in series with an air filter, a trip...
