Technical Field
The invention relates to the technical field of detection tools, in particular to a bulge go-no-go gauge.
Background
At present, domestic products for detecting bulges are simple in structure and extremely high in requirements on processing technology and measurement, measurement deviation exists in the problem of a measuring point when three-coordinate measurement is used, the problem that important dimensions are not accurate easily results, and in addition, the problem of stroke limitation exists when a contourgraph is used for measurement.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: in order to solve the problems existing in the background technology, an improved bulge go-no-go gauge is provided, and the problems that the bulge go-no-go gauge on the market at present is simple in structure, extremely high in processing technology and measurement requirements, and meanwhile, measurement is not accurate enough and the stroke is limited are solved.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a swell and lead to no-go gage, includes hollow structure main barrel, the nearly left side opening position of main barrel inside wall seted up built-in annular assembly groove, the horizontal length of built-in annular assembly groove is 5mm, the horizontal length of main barrel is 50mm, main barrel hole diameter size be 39.46mm, the interior aperture size of built-in annular assembly groove is 40.7 mm.
Further, the main barrel body lateral wall be located right side open position and seted up external annular adjustment tank, external annular adjustment tank left side wall and main barrel contact surface on seted up annular flexible groove, the inside cover of external annular adjustment tank have annular flexible cover, annular flexible cover and external annular adjustment tank contact surface on begin to seted up the notch cuttype spacing groove, annular flexible cover in the inboard side have with the inside flexible cover of annular flexible groove matched with annular, the inboard arcwall face of annular flexible inslot have the internal thread connection face that is used for connecting and adjusts the flexible cover of annular, annular flexible cover through the inside internal thread connection face threaded connection of the flexible inslot portion of the flexible inslot of annular flexible cover screw in annular with the flexible inslot portion of annular.
Furthermore, a plurality of strip-shaped openings communicated with the inside of the annular telescopic groove are formed in the outer side wall of the main cylinder body.
Furthermore, no gap exists between the inner side surface of the annular telescopic sleeve and the outer side surface of the external annular adjusting groove.
The bulge go-no-go gauge has the advantages that the design that the inner wall of the left side is provided with the built-in annular assembling groove and the outer wall of the right side is provided with the external annular adjusting groove is adopted, the main cylinder body is inserted into the steel pipe and is matched with the height gauge for direct measurement, so that the measurement requirement is met, the measurement consistency is ensured, the rapid measurement is completed, the detection can be realized, meanwhile, the measurement error caused by artificial point taking factors is avoided, the reliability and the repeatability are strong, the measurement requirement is met, and the measurement stroke is greatly improved through the annular telescopic sleeve with the length capable of being adjusted in a rotating mode.
Drawings
The invention is further illustrated with reference to the following figures and examples.
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic view of the internal structure of the annular expansion groove in the present invention.
In the figure, the device comprises a main cylinder body 1, an annular assembly groove 2, an external annular adjusting groove 3, an annular telescopic groove 4, an annular telescopic sleeve 5, a stepped limiting groove 6, an annular telescopic sleeve 7 and a strip-shaped opening 8.
Detailed Description
