The specific embodiment is as follows:
The ring gauge 1 includes a first gauge body 11, a second gauge body 13, and a hinge member 12. The first gauge body 11 and the second gauge body 13 are both arc-shaped, and the first gauge body 11 and the second gauge body 13 are oppositely connected to form a complete standard circular ring. A first internal thread 111 is arranged in the first gauge body 11, and is a part of the complete internal thread after being longitudinally cut; a second internal thread 131 is arranged in the second gauge body, and the second internal thread 131 is also a part of the complete internal thread after longitudinal cutting; when the first gauge body 11 and the second gauge body 13 are combined into a standard circular ring, the first internal thread 111 and the second internal thread 131 form a complete internal thread, namely a ring gauge thread.
The ends of the first and second gauges 11 and 13 are connected by a hinge 12. In the present embodiment, the hinge member 12 includes a first bracket and a second bracket; the first bracket is connected with the end part of the first gauge body 11, and a first connecting ring is arranged at the end part of the first bracket close to the second gauge body 13; the second bracket is connected to the end of the second gauge body 13, and a second connecting ring is arranged at the end of the second bracket close to the first gauge body 11; the inner diameters of the first and second connection rings are identical, and the first and second connection rings are overlapped front and back when the first and second compasses 11, 13 are combined into a standard circular ring, and a connection column is penetrated and connected into the first and second connection rings, so that the hinge parts 12 are connected into a whole, and the connection of the first and second compasses 11, 12 is realized.
As an example of the present embodiment, the first blade 11 is of a semicircular ring structure, i.e., a portion of a complete circular ring cut longitudinally along its centerline; suitably, the second gauge 13 also adopts a semicircular ring structure, consistent with the structure of the first gauge 11. When the first gauge body 11 and the second gauge body 13 are opened, the openings of the first gauge body 11 and the second gauge body 13 can be guaranteed to be the largest, and the ring gauge 1 can be conveniently lapped on a product 5 to be measured.
The numerical value detection device 2 includes an anvil 23 and a dial indicator 21. The numerical value detection device 2 is used for detecting the difference value between the external thread 51 of the product 5 to be detected and the ring gauge 1. The anvil 23 is attached to the side of the end of the first gauge body 11 remote from the hinge member 12. The dial indicator 21 is connected to the side of the end of the second gauge body 13 remote from the hinge member 12, the dial indicator 21 and the anvil 23 are on the same side of the ring gauge 1, and the measuring rod of the dial indicator 21 is vertically opposite to the anvil 23.
