Problems solved by technology

Moreover, since the tolerance of the internal diameter of the inner measuring surface of the threaded ring gauge body is very small, usually about 8 μm, the adjustment has disadvantages such as difficulty and difficulty in adjustment.

Embodiment Construction

[0034] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:

[0035] Please refer to Figures 1 to 3 As shown, the threaded ring gauge of the first embodiment of the present invention includes a body 1 , an adjustment element 2 , at least one positioning groove 3 a and a gauge 4 a.

[0036] The main body 1 is provided with a slit 10 , a first block 11 , a second block 12 , an inner ring surface 13 , an outer ring face 14 , a first hole 15 and a second hole 16 . The body 1 is formed with the first block 11 and the second block 12 by the slit 10, and the slit 10 forms a gap P between the end faces of the first block 11 and the second block 12; The ring surface 13 forms an inner diameter of the inner measuring surface, and the inner ring surface 13 is provided with threads fo...

Abstract

A threaded ring gauge comprises a body, at least one adjusting element, at least one positioning groove and a gauge. The body is provided with an inner ring surface and an outer ring surface. The inner ring surface is provided with threads for contact detection of the object to be tested. There is a gap between the inner ring surface and the outer ring surface so that the body forms a first block and A second block, and the two blocks form the crack from the end face, the first block has at least one first hole, the second block has at least one second hole, the first and second holes Located on the same axis and running through the end faces of the two blocks, and at least one hole passing through the outer ring surface; the at least one adjusting element is passed through the first hole and the second hole, and is used to separate or draw The two ends of the crack body are fixed; at least one positioning groove is arranged at at least one of the two ends of the body, and extends toward the outer ring surface to form an opening; the block gauge is accommodated in the positioning groove Inside.

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...
