Abstract
The utility model discloses an internal diameter dial indicator. The internal diameter dial indicator is characterized in that an indicator body is provided with a press sleeve, the press sleeve comprises a first external diameter, a second external diameter and a halfpace, the halfpace and the first external diameter are connected with two ends of the second external diameter, the first external diameter is identical to an internal diameter of a product to be detected in a design dimension, an external diameter dimension of the halfpace is greater than that of the second external diameter, the second external diameter is greater than the first external diameter in dimension, a calibrating device is set to be a standard sleeve, and an internal diameter dimension of the standard sleeve is identical to the design dimension of the second external diameter. Compared with the prior art, the internal diameter dial indicator is convenient for a worker to detect a groove external diameter of an internal hole of a deep hole on a workpiece and guarantees precision on workpiece measuring.
Description
Technical field
The utility model relates to pick-up unit, particularly a kind of dial bore gage.
Background technology
The dial bore gage table is the combination of interior amount lever measurement bay and dial gauge, is that measurement instrument that straight-line displacement with gauge head becomes the angular displacement of pointer is measured with comparative measurement method or endoporus, deep hole diameter and the form accuracy thereof of check part.Existing internal diameter measuring instrument mostly can only be simple the measuring workpieces internal diameter size, have than deep trouth and need to measure if run into internal diameter, very inconvenient measurement causes measuring out of true easily.
The utility model content
The utility model technical issues that need to address are the deficiencies at above-mentioned technology, and provide a kind of structuring concept clear, and are easy to operate, satisfy the dial bore gage of measuring hole slot external diameter in most of deep hole.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of dial bore gage is characterized in that at table gland being set on one's body, and described gland comprises first external diameter, second external diameter and halfpace; Halfpace and first external diameter are connected the second external diameter two ends; First outside dimension is identical with the design size of survey product internal diameter size; Described halfpace outside dimension is greater than second outside dimension, and second outside dimension is greater than first outside dimension; It is the standard cover that a calibrating installation is set, and standard cover internal diameter size is identical with the design size of second outside dimension.
Compared with prior art, dial bore gage of the present utility model provides a kind of novel metering system and surveying instrument, and structuring concept is clear, calculates simply, and it is convenient to measure, and more accurate.
Description of drawings
Fig. 1 is the dial bore gage synoptic diagram;
Fig. 2 is standard cover synoptic diagram;
Fig. 3 is this product structure synoptic diagram;
Among the figure, product that 1-surveys, the 2-gauge head, the 3-bar, the 4-gland, the 5-dial gauge, 6-standard cover, 7-shows body, 8-first external diameter, 9-second external diameter, 10-halfpace.
Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
As Fig. 1, shown in 2 and 3, a kind of dial bore gage is characterized in that at table body 7 gland 4 being set, and described gland 4 comprises first external diameter, 8, the second external diameters 9 and halfpace 10; Halfpace 10 and first external diameter 8 are connected second external diameter, 9 two ends; First external diameter, 8 sizes are identical with the design size of survey product 1 internal diameter size; Described halfpace 10 outside dimensions are greater than second external diameter, 9 sizes, and second external diameter, 9 sizes are greater than first external diameter, 8 sizes; It is standard cover 6 that a calibrating installation is set, and it is identical with the design size of second external diameter, 9 sizes that standard is overlapped 6 internal diameter sizes.
Select length and the product of surveying 1 the internal diameter gauge head 2 and the bar 3 that adapt, both gauge head 2 was identical with the length of bar 3 selections, gauge head 2 is connected the length of showing body 7 with bar 3 identical with survey product 1 internal diameter size, dial bore gage is put into the standard cover, behind the correction card, remove bar 3, gauge head 2 is put into the hole slot of the product of surveying 1, the data that stem is measured are the hole slot outside dimension; The product of measuring other sizes if desired need be changed gland the 1st external diameter 8 sizes and get final product.
Claims (2)
