Abstract
A kind of new aperture inside groove calipers, including base, the base upper end are fixed with support, support is provided with digital display height slide calliper rule, the digital display height slide calliper rule side is provided with dial test indicator, and dial test indicator side is provided with measuring staff, and described measuring staff one end is vertically and fixedly provided with test hook.The utility model solves the problem of can not being measured for the conventional utensil of middle trough is deep and narrow, two aperture is small and deep this type irregular part, easily aperture groove-bottom diameter can be measured, improve testing accuracy.
Description
Technical field
The utility model is related to a kind of new aperture inside groove calipers.
Background technology
At present, larger for aperture, the measuring method in more regular part hole inner side slot footpath is, it is necessary to measurement every time
When all on slide measure increase by two measurement claws and a dial gauge measure.
But, two aperture small irregular part deep and narrow for the trough in centre position on the inside of hole, there is band pawl
The slide measure of card, which enters, not to be gone, micrometer amount not, the problem of can not all being measured with universal tool-measuring microscope and universal comparator.
Utility model content
Its purpose of the utility model is that a kind of new aperture inside groove calipers of offer, solves for medial launder
The problem of conventional utensil of this small and deep type irregular part of sub deep and narrow, two aperture can not be measured.
The technical scheme realized above-mentioned purpose and taken, including base, the base upper end is fixed with support, support and set
There are digital display height slide calliper rule, the digital display height slide calliper rule side is provided with dial test indicator, and dial test indicator side is provided with measuring staff, described
Measuring staff one end is vertically and fixedly provided with test hook.
Beneficial effect
The utility model, which has, compared with prior art following has advantage.
1., can be according to measured hole with certain versatility, it is adaptable to the hole groove-bottom diameter measurement of various irregular parts
The actual conditions of footpath inside groove, change different test hooks, measure the groove footpath in various apertures；
2. measurement accuracy is high, ± 0.001mm can reach.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation in aperture measured by the utility model.
Embodiment
The present apparatus includes base 4, as shown in figure 1, the upper end of the base 4 is fixed with support 5, support 5 is high provided with digital display
Slide calliper rule 1 are spent, the side of digital display height slide calliper rule 1 is provided with dial test indicator 2, and the side of dial test indicator 2 is provided with measuring staff 3, described to survey
The one end of bar 3 is vertically and fixedly provided with test hook 6.
The test hook 6 can change various sizes of test hook according to the actual conditions of tested groove footpath size.
The specific implementation steps of the utility model are：
1st, tested part is set, makes tested part parallel with measuring staff 3；
2nd, test hook 6 is stretched into the trough in hole, finely tuned inward, test hook 6 is found minimum point in groove；
3rd, dial test indicator 2 is transferred to zero-bit, then digital display height slide calliper rule 1 is zeroed；
The 4th, test hook 6 is placed on to the minimum point in hole；
5th, measuring staff 3 is finely tuned outward, dial test indicator 2 is gone to zero-bit；
6th, reading, acquired results are a.
The utility model measuring principle, as shown in Fig. 2 a diameter of D in hole, groove depth is a, groove footpath d=D+2a.Wherein D survey
Amount, with conventional slide measure direct measurement.The utility model is mainly used in a measurement.
