1 Scope

The order applies to basic dimensions of the hole and shaft to 500mm, tolerance grade IT6 level to level IT16 proofreading, workers As smooth limit gauge the initial verification, subsequent verification and the use of checks. 2. References This procedure references the following documents. GB/T 1800.1-2009 Geometrical product specifications (GPS) limits and fits - Part 1.

3 terminology and units of measurement

JJF1001-2011 "common measurement terms and definitions", GB/T 1957-2006 "smooth limit gauge technology Intraoperative conditions "and as defined in the following terms and definitions apply to this procedure. 3.1 smooth limit gauge plainlimitgauges With a maximum limit size of the hole or shaft or the minimum size limit for the nominal size of a standard measurement surface can reflect control Made the subject hole or shaft boundary conditions of no moment length measuring instruments.

4 Overview

Smooth limit gauge (hereinafter referred to as "gauge") is divided into plug, ring and caliper three categories. Smooth limit plug gauge is used to test the aperture, the measurement surface of the outer cylinder, sphere and the like. Wherein the plug Having a pore size subject to minimum limit size hole through regulation, having a hole with a maximum limit of detection aperture size Only the rules. Ring gauge smooth limit gauge for inspection shaft diameter, the measurement surface within a torus. Wherein the diameter of the ring Having a through-axis inspection regulations limit the size of the largest shaft diameter, shaft diameter has been the subject of an axis with a minimum size limit Only the rules. Caliper is smooth limit gauge for inspection shaft diameter, its surface is measured in two parallel surfaces. Among them, the two measuring surface Pitch having a through-shaft Shaft Inspection Regulations limit the maximum size of the subject having an axis shaft diameter with a minimum size limit Only the rules. Shafts smooth limit gauge the structure shown in Figure 1. Holes in Figure 2 with a smooth structure limit gauges FIG.
