In the figure: 1. a threaded ring; 2. an adjusting block; 3. a thread detection block; 4. a support mechanism; 41. connecting columns; 42. a telescopic rod; 43. a spring; 5. a dovetail groove; 6. a dovetail block; 7. and (6) positioning the bolt.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a screw adjustment type thread ring gauge comprises a thread ring 1, wherein a plurality of adjusting blocks 2 are arranged on the inner side of the thread ring 1, thread detecting blocks 3 are arranged on the inner sides of the adjusting blocks 2, and supporting mechanisms 4 are arranged on the inner sides of the adjusting blocks 2;

the inboard of regulating block 2 is provided with dovetail 5, the inboard of dovetail 5 is provided with dovetail 6, dovetail 6 detects 3 fixed connection of piece with the screw thread, the through-hole has been seted up on regulating block 2, be provided with positioning bolt 7 in the through-hole, set up on dovetail 6 with positioning bolt 7 assorted screw, the screw thread has been seted up to the inboard that the screw thread detected piece 3, set up on regulating block 2 with 1 assorted external screw thread of screw thread ring, regulating block 2 is the wedge, supporting mechanism 4 includes spliced pole 41, a plurality of telescopic links 42, spring 43, a plurality of telescopic link 42 fixed mounting is on spliced pole 41, the outside at telescopic link 42 is established to spring 43 cover, telescopic link 42 and the 2 fixed connection of regulating block that correspond.

The working principle is as follows: when the adjustable screw thread detection block is used, when the inner diameter of the screw thread ring 1 gauge needs to be adjusted to be large, the screw thread ring 1 is rotated reversely, the screw thread ring 1 moves downwards along the adjusting block 2, the adjusting block 2 is pushed to move outwards through the elastic force of the spring 43, the screw thread detection block 3 is driven to move outwards, the inner diameter of the screw thread ring 1 gauge is increased, when the inner diameter of the screw thread ring 1 gauge needs to be adjusted to be small, the screw thread ring 1 is rotated forwardly, the screw thread ring 1 moves upwards along the adjustment, the adjusting block 2 is extruded, the spring 43 is compressed, the screw thread detection block 3 is pushed to move inwards, the inner diameter of the screw thread ring 1 gauge is reduced, the problem that the detection accuracy is affected due to the fact that the sizes of the dovetail block 6 and the dovetail groove 5 are not accurate enough is avoided through the positioning bolt 7, when the inner side screw threads of the screw thread detection block 3 are seriously worn and need to be replaced, the corresponding positioning bolt 7 of the screw thread detection block 3 is taken down, and the screw thread detection block 3 and the dovetail block 6 can be taken down, the adjustable inner diameter, Convenient maintenance and replacement.
