Embodiment
The embodiment of the utility model is described with detailed reference to attached drawing now.Now with detailed reference to the excellent of the utility model
Embodiment is selected, its example is shown in the drawings.In the case of any possible, will be come in all of the figs using identical mark
Represent the same or similar part.In addition, although the term used in the utility model is selected from public term
Select, but some terms mentioned in the utility model specification are probably applicant to be selected by his or her judgement
, its detailed meanings illustrates in the relevant portion of description herein.In addition, it is desirable to not only by used actual art
Language, and the meaning that is also to be contained by each term understands the utility model.
Refer to the attached drawing discusses the basic principle of the utility model and preferred embodiment in more detail.Fig. 3 and Fig. 4 are shown
One example of ultrasonic flowmeter 1.The ultrasonic flowmeter 1 mainly includes two pairs of window parts 2, which, which has, is used for
Accommodate the chamber of ultrasonic signal transmission element (for example, ultrasonic wave radiated element and/or ultrasonic wave receiving element).Wherein, often
Obliquely it is arranged at the opposite both sides of the pipeline section of ultrasonic flowmeter 1, and the axis of each pair window part 2 respectively to window part 2
Need to be formed on the same line.In addition, to also need to packaging material parallel for the two neighboring window part 2 at the same side, and there is size
It is required that.Therefore, when window part 2 is soldered on the pipeline section of ultrasonic flowmeter 1, to each window in two pairs of window parts 2
The relative position relation of mouth part has higher required precision.
Fig. 1 and Fig. 2 are gone to, they show one embodiment of fixture 10 according to the present utility model.The fixture 10 has
Help that the two neighboring window part 2 positioned at pipeline section the same side is accurately positioned, to ensure that its relative position relation meets required precision.
The fixture 10 mainly includes the first positioning column 11, the second positioning column 12 and latch components 13.First positioning column, 11 He
Second positioning column 12 has first end and the second end opposite with first end being adapted for insertion into the chamber of window part 2.According to
One embodiment, can cause the interior of the outside diameter of the above-mentioned first end of the first positioning column 11 and the second positioning column 11 and window part 2
Footpath is identical, to obtain preferable locating effect.
In addition, latch components 13 further comprise matching each other and 14 and second fastener 15 of the first fastener independent of each other.
Recess is respectively arranged with the side relative to each other of first fastener 14 and the second fastener 15.In this way, by 14 He of the first fastener
When second fastener 15 is combined to form latch components 13, formed with two through holes, (through hole is by latch components 13
The corresponding recess of one fastener 14 and the second fastener 15 is formed).It is fixed that the two through holes latch the first positioning column 11 and second
Above-mentioned second end on the column 12 of position, so that the relative position relation of the first positioning column 11 and the second positioning column 12 keeps solid each other
It is fixed.
For example, annular groove can be formed at the above-mentioned second end of the first positioning column 11 and the second positioning column 12, wherein
The internal diameter of through hole is identical with the outside diameter of annular groove.
Alternatively, in order to avoid filling by mistake, first annular groove can also be formed at the second end of the first positioning column 11 respectively
And second annular groove is formed at the second end of the second positioning column 12.Wherein, the outside diameter of first annular groove and the second annular
The outside diameter of groove is different from each other, identical with the outside diameter of first annular groove with the internal diameter of the corresponding through hole of first annular groove,
It is and identical with the outside diameter of second annular groove with the internal diameter of the corresponding through hole of second annular groove.
In this way, it can be covered respectively on the first positioning column 11 and the first end of the second positioning column 12 positioned by fixture 10
The two window parts 2 that fixture 10 positions are inserted into the corresponding position on the pipeline section of ultrasonic flowmeter and implement weldering by window part 2
Connect, and remove fixture 10 from window part 2 after welding has been completed.Therefore, the fixture 10 of the utility model can ensure two windows
Relative position relation of the mouth part 2 in welding process keeps stablizing, and improves the accuracy of manufacture of product.
Above-mentioned through hole is opened in the upper and lower surface of the first fastener 14 and the second fastener 15.In addition, according to one
A embodiment, can each offer on the side wall of the first fastener 14 and the second fastener 15 through the first fastener 14 and the second button
The connecting hole 16 of part 15.First fastener 14 and the second fastener 15 are combined with each other by the connector 17 through connecting hole 16.As
One example, is threaded structure on the inner wall of connecting hole, and above-mentioned connector is screw.Sometimes, metal caused by welding
Thermal deformation can lead to not take out a whole set of fixture 10 from window part 2.At this point it is possible to the first button is disassembled by above-mentioned connector
14 and second fastener 15 of part, and then the first positioning column 11 and the second positioning column 12 are removed respectively.
To sum up, the fixture of the utility model can help to stablize two window parts of ultrasonic flowmeter in welding process
