Abstract

The invention relates to a thread ring gauge. The thread ring gauge comprises a main body, at least one adjusting element, at least one locating slot and a block gauge, wherein the main body is provided with an inner ring surface and an outer ring surface; the inner ring surface is provided with a screw thread used for the contact inspection of an object under test; a gap is arranged between the inner ring surface and the outer ring surface to ensure the main body to form a first block and a second block, the end surfaces of the two blocks are used to form the gap; the first block is provided with at least one first hole, the second block is provided with at least one second hole, the first and second holes are positioned on the same axis and penetrate through the end surfaces of the two blocks, at least one hole penetrates through the outer ring surface; the adjusting element penetrates through the first and second holes and is used to draw or undrawn the two ends of the gap main body and also used for fixing; the locating slot is arranged on at least one end of the two ends of the main body and extends to the outer ring surface to form an opening; and the block gauge is holden in the locating slot.

Description

technical field [0001] The present invention relates to a threaded ring gauge, and more particularly to a threaded ring gauge which can be used to reduce the inner diameter of the inner measuring surface. Background technique [0002] Existing thread ring gauges use the measuring threads on the inner measuring surface of the ring gauge body to detect whether the thread of the screw or screw meets the specifications. Therefore, the precision of the thread ring gauge is extremely high, while the inner measuring surface of the existing thread ring gauge The inner diameter is divided into a fixed size method and a method that can reduce the inner diameter of the inner measurement surface. [0003] Among them, the threaded ring gauge of the fixed size method taps an internal measuring thread of a predetermined size from a body, because the internal measuring thread of the threaded ring gauge of the fixed size method cannot be changed, therefore, the thread of the internal measuri...
