Abstract

The invention provides an inner diameter measurement auxiliary sleeve for a vernier caliper. The inner diameter measurement auxiliary sleeve for the vernier caliper can conveniently measure the aperture sizes of the same hole with different inner diameters and is characterized by comprising a measurement foot fixed end of the vernier caliper and a measurement end, wherein the measurement foot fixed end of the vernier caliper is provided with a datum plane; and the measurement end is provided with a bump and is matched with the inner diameters of the measured hole.

Description

A kind of vernier caliper inner diameter measurement auxiliary sleeve
Technical field
The present invention relates to the technical field of survey instrument, be specially a kind of vernier caliper inner diameter measurement auxiliary sleeve.
Background technology
When using the aperture in the vernier caliper measurement degree of depth same hole darker, that internal diameter does not wait, because the limitation of the measurement pin of vernier caliper, hole internal diameter dark and that do not wait with inner end diameter can't fathom.
Summary of the invention
At the problems referred to above, the invention provides a kind of vernier caliper inner diameter measurement auxiliary sleeve, can measure the aperture size that internal diameter does not wait in the same hole easily.
Its technical scheme is such: a kind of vernier caliper inner diameter measurement auxiliary sleeve, it is characterized in that: the measurement pin stiff end and the measuring junction that comprise vernier caliper, the measurement pin stiff end of described vernier caliper has a reference field, described measuring junction has a projection, and described measuring junction and measured hole internal diameter adapt.
It is further characterized in that: the measurement pin stiff end of described vernier caliper comprises bolt and vernier caliper measurement pin patchhole.
In the said structure of the present invention, owing to adopted the measurement pin stiff end of vernier caliper and the measuring junction that adapts with the measured hole internal diameter, hole internal diameter dark and that do not wait with inner end diameter easily can fathom.
Description of drawings
Fig. 1 is a vernier caliper inner diameter measurement auxiliary sleeve master sectional structure synoptic diagram of the present invention;
Fig. 2 is a vernier caliper inner diameter measurement auxiliary sleeve plan structure synoptic diagram of the present invention.
Embodiment
See Fig. 1, Fig. 2, a kind of vernier caliper inner diameter measurement of the present invention auxiliary sleeve, the measurement pin stiff end 3 and the measuring junction 5 that comprise vernier caliper, the vernier caliper measurement pin is fixing by vernier caliper measurement pin patchhole 4 and bolt 2, the measurement pin stiff end 3 of vernier caliper has a reference field 1, measuring junction 5 has a projection 6, the projection 6 and the measured hole internal diameter of measuring junction 5 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 processing vernier caliper inner diameter measurement auxiliary sleeve, when the hole depth measured, can the extend entire length of vernier caliper inner diameter measurement auxiliary sleeve is when the internal diameter of measuring is a narrow groove, as long as process the projection on the measuring junction 56 narrower, as long as hole that measuring junction can be put into required measurement and the adaptation of the internal diameter in hole, two vernier caliper inner diameter measurement auxiliary sleeves are separately fixed at just can measure internal diameter does not wait in the same hole aperture size easily on two measurement pin of vernier caliper.
Certainly the fixing means of vernier caliper measurement pin 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 vernier caliper measurement pin.

Claims (2)

1. vernier caliper inner diameter measurement auxiliary sleeve, it is characterized in that: the measurement pin stiff end and the measuring junction that comprise vernier caliper, the measurement pin stiff end of described vernier caliper has a reference field, and described measuring junction has a projection, and described measuring junction and measured hole internal diameter adapt.
2. a kind of vernier caliper inner diameter measurement auxiliary sleeve according to claim 1 is characterized in that: the measurement pin stiff end of described vernier caliper comprises bolt and vernier caliper measurement pin patchhole.
