Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 6314-2004 "Three-claw inner diameter micrometer". This standard is compared with GB/T 6314-2004, except for editorial repair
In addition, the main technical changes are as follows.
--- Revised the scope of application of the standard (see Chapter 1, Chapter 1 of the.2004 edition);
--- Redefining related terms (see Chapter 3, Chapter 3 of the.2004 edition);
--- Re-specified the measurement range of the three-claw inner micrometer and its corresponding relationship with the range (see 4.3,.2004 edition 4.2);
--- Increased the requirement for measuring paw interaction (see 5.2);
--- Increased the requirements for the interchangeability of the three-claw inner micrometer probe (see 5.2.3);
--- Revised the requirements for materials required for measuring jaws and measuring heads (see 5.3, 5.2 of.2004 edition);
--- Increased the requirement for scale marking and its coincidence (see 5.4);
--- Added requirements for zero adjustment device, screw pair wear adjustment device and extension rod (see 5.5);
--- Revised the requirements for the force measuring device and its force measurement value (see 5.6, 5.3 of the.2004 edition);
--- Revised the requirements for the shape of the measuring surface and the hardness and surface roughness of the measuring surface (see 5.7.1, 5.7.4, 5.4.1 of the.2004 edition);
--- Increased the requirements for the shape of the special-purpose measuring surface and the requirements of the two-point measuring surface (see 5.7.2, 5.7.3);
--- Re-principle the principle of maximum allowable error and error determination of the indication (see 5.8, 5.7 of.2004 edition);
--- Redefined the technical requirements for the proofreading ring gauge (see 5.9, 5.7 of the.2004 edition);
--- Increased the requirements for inspection conditions (see Chapter 6);
--- Added the content of the inspection method, supplemented the appearance, interaction, scale marking and its coincidence, inspection and measurement of various devices
Inspection methods for items such as face (see Chapter 7);
--- Revised the test method for proofreading ring gauges, and unified with relevant standards (see 7.8,.2004 edition 6.2).
This standard was proposed by the China Machinery Industry Federation.
