Abstract
The invention provides an auxiliary sleeve of a depth gauge for measuring a hole internal groove, which can conveniently measure the size of the hole internal groove or from the lower end face of a protrusion to the end of a hole and ensure the processing precision of parts. The auxiliary sleeve is characterized by comprising a gauge rod fixed end and a measurement end of the depth gauge, wherein the measurement end is provided with at least one protrusion, the upper and lower end faces of the protrusion of the measurement end are reference surfaces, and the protrusion of the measurement end is adapted with the measured hole internal groove.
Description
Technical field
The present invention relates to the technical field of survey instrument, be specially a kind of pit gauge measured hole inside groove auxiliary sleeve.
Background technology
When being provided with groove or when projection in the hole, just have no idea to measure with pit gauge and portal inside groove or protruding lower surface to the size of bore ends, influence the processing of part with holes.
Summary of the invention
At the problems referred to above, the invention provides a kind of pit gauge measured hole inside groove auxiliary sleeve, can measure portal inside groove or protruding lower surface easily to the size of bore ends, guaranteed the machining precision of part.
Its technical scheme is such: a kind of pit gauge measured hole inside groove auxiliary sleeve, it is characterized in that: the chi bar stiff end and the measuring junction that comprise pit gauge, described measuring junction has a projection at least, the upper and lower end face of projection is a reference field on the described measuring junction, and described measuring junction projection adapts with the measured hole inside groove.
It is further characterized in that: the chi bar stiff end of described pit gauge comprises the chi bar patchhole of bolt and pit gauge; Projection is two on the described measuring junction.
In the said structure of the present invention, owing to adopted the chi bar stiff end of pit gauge and the projection that adapts with measuring junction measured hole inside groove, can measure portal inside groove or protruding lower surface easily, guarantee the machining precision of part to the size of bore ends.
Description of drawings
Fig. 1 is a pit gauge measured hole inside groove auxiliary sleeve master sectional structure synoptic diagram of the present invention.
Embodiment
See Fig. 1, a kind of pit gauge measured hole inside groove auxiliary sleeve, the chi bar stiff end 1 and the measuring junction 4 that comprise pit gauge, the chi bar of pit gauge is fixing by the chi bar patchhole 3 and the bolt 2 of pit gauge, two protruding 7-1,7-2 are arranged on the measuring junction 4, upper surface 6-1, the 6-2 of two protruding 7-1,7-2 and lower surface 5 are reference field on the measuring junction 4, and measuring junction projection 7-1,7-2 and measured hole inside groove adapt.
When the aperture is big, size is amplified when processing vernier caliper inner diameter measurement auxiliary sleeve, aperture hour, size is put little during working depth chi measured hole inside groove auxiliary sleeve, when the hole depth measured, the entire length of the pit gauge measured hole inside groove auxiliary sleeve that can extend is when the internal diameter of measuring is a narrow groove, if narrower protruding 7-1 on the measuring junction 4 or 7-2 processing, as long as measuring junction can adapt with the hole inside groove of required measurement.
Certainly the fixing means of the chi bar of pit gauge also is not limited to the fixing means of embodiment, can adopt conventional fixing meanss such as welding, as long as can be fixing the chi bar of pit gauge.
Claims (3)
1. pit gauge measured hole inside groove auxiliary sleeve, it is characterized in that: the chi bar stiff end and the measuring junction that comprise pit gauge, described measuring junction has a projection at least, and the upper and lower end face of projection is a reference field on the described measuring junction, and described measuring junction projection adapts with the measured hole inside groove.
2. according to the described a kind of pit gauge measured hole inside groove auxiliary sleeve of claim 1, it is characterized in that: the chi bar stiff end of described pit gauge comprises the chi bar patchhole of bolt and pit gauge.
3. according to the described a kind of pit gauge measured hole inside groove auxiliary sleeve of claim 1, it is characterized in that: projection is two on the described measuring junction.
