Description
Technical field
The present invention relates to a kind of ring gauges, especially suitable for using when the detection of small size tube outer diameter.
Background technique
Ring gauge is also correction ring gauge, is insufficient a kind of annulus with specific dimensions and attribute for correcting measurer.
Ring gauge according to can be divided into appearance: smooth surface ring gauge (ring of light is also made to advise), ring screw gauge, parallel thread ring gauge etc.；According to purposes with
And the difference of manufacturer's standard can be divided into: ring standard gauge, SK ring standard gauge, German Standard ring gauge, effective ring gauge etc.；According to manufacture
Material obtains the different differences that can also have ceramic ring gauge and metal ring gauge.
Pipe-type article used in the cool-heat-exchanger of white domestic appliances is more, to the pipe of different tubing, different size
Outer diameter requires also more.Ring gauge on the market is all the effective ring gauge of made of metal of smooth surface at present, wherein can be divided into " single layer single hole
Shown in ring gauge " and my company " single layer diplopore ring gauge " (such as Fig. 1 and Fig. 2) currently in use.
Usually there is an only hole 1 in my company single layer diplopore ring gauge structure currently in use, another is through-hole 2, detection
When, tested tubing is inserted into respectively in through-hole 2 and only hole 1, pipe end can smoothly be inserted into through-hole 2, and can not be inserted into only hole 1
Side is qualification, and the diameter of the through-hole is greater than detected tubing, and 4.76+0.05/-0 of Φ, the aperture in the only hole is small
In detected tubing, 4.76+0/-0.05 of Φ, the design of the diameter in the diameter of through-hole and only hole is just to be detected tubing
Within the scope of the qualification of permission.Through-hole 2 on prior art ring gauge is opened in the center of ring gauge, and only hole is opened in the edge of ring gauge
Place, this design part extra in addition to working portion is relatively more, wastes material, and ring gauge overall weight weight, is unfavorable for existing
Field detecting.Tubing only can be passed through through-hole with feeling to save the time by some skilled staffs, and only stop hole, to increase
Product disqualification rate, induces the generation of security risk.
Summary of the invention

For the ring gauge 5 as shown in Fig. 5, Fig. 6, Fig. 7, Fig. 8, ring gauge is two, and the ring gauge of ring gauge through-hole is placed on only hole
Above and consistency from top to bottom is filled in the U-shaped mouth of U-shaped card, and for the ease of user's differentiation, and the outer shape of two ring gauges is different
Sample, an end face be machined with ring gauge stop hole this ring gauge shape be in unfilled corner positive eight prismatic 5-2, in order to guarantee processing stop
The center in hole is machined with an only hole cutting seam 5-3, only in the centre of ring gauge on a rib prismatic in unfilled corner positive eight
The determination at hole center is to be subject to the only hole cutting seam processed on ring gauge, and the outer shape of another ring gauge is prismatic in eight, eight
A through-hole cutting seam 5-1 is machined on a prismatic rib, the determination of through hole center is to process on another ring gauge
Subject to through-hole cutting seam.
The U-shaped card is as shown in Figure 9, Figure 10, and U-shaped card includes that tooth 4-3, card are fixed outside for outer tooth 4-1, interior tooth 4-2, card
Hole 4-4, card 4-5, U-shaped mouth 4-6, edge 4-7, card interior tooth 4-8, U-shaped card are that two ring gauges are placed to U-shaped mouth in order to prevent
In up and down loosen and design, the side of the card 4-5 hollow out constitute one storing two ring gauges U-shaped mouth, in U-shaped mouth edge
Top be provided with outer tooth 4-1, interior tooth 4-2, neighbouring U-shaped mouth card 4-5 on be machined with card fixation hole 4-4, and edge
Top is provided with card interior tooth 4-8 and the outer tooth 4-3 of card, and the U-shaped card plug enters in housing, and outer tooth 1 and interior tooth 2 can fall into housing
In the age of a draught animal of processing, prevent from filling in excessive, card fixation hole and the fixation hole for putting on processing outside are concentric to be passed through with screw by housing
It is fixed with U-shaped card.
As is illustrated by figs. 11 and 12, housing is to play the role of fixed and protect ring gauge and U-shaped card, housing to the housing 3
Including fixation hole 3-1, housing cutting seam 3-2, step 3-3, age of a draught animal 3-4, strip openings 3-5, access mouth 3-6 and housing
Inner cavity one end is strip openings, and the housing inner cavity other end is the access mouth for clamping ring gauge, the strip openings
The housing lengthwise position of one end is machined with housing cutting seam, it is therefore an objective to prevent anti-set from opening deformation because long-time uses, and long
The other end of bar shaped openings is communicated with the access mouth of the housing inner cavity other end, age of a draught animal 3-4 process access mouth one end and with
The other end of long strip type openings is corresponding.The outside of housing 3 is provided with step 3-3, it is therefore an objective to prevent nut autobiography, and strip
The housing external process of this one end of shape openings has housing fixation hole 3-1, and housing fixation hole and card fixation hole Working position
It should correspond to, housing fixation hole and card fixation hole are concentric after each module assembled.
The assembling of combined type single hole bilayer ring gauge stops on the upper surface of hole 1 as shown in figure 4, ring gauge through-hole 2 is placed on ring gauge
