Abstract

The utility model relates to the measuring tool field, and discloses an external diameter continuous measuring instrument which is composed of a movable support, a movable measuring unit, and a connecting rack which connects the movable rack with the movable measuring unit. The movable support is sleeved on a fixing measuring head. The fixing measuring head is fixed on the connecting rack. The movable rack includes an upper centering member and a lower centering member. A connecting line of an outer end of the upper centering member and an outer end of the lower centering member evenly and vertically divides the fixing measuring head. The beneficial effects are that through continuously measuring the external diameter of a pipeline, the precision of the pipeline external diameter measurement is greatly improved and the working efficiency is increased.

Description

The external diameter continuous meter
Technical field
The utility model relates to the survey instrument field, particularly a kind of external diameter continuous meter.
Background technology
In the present on-the-spot actual production, in the pipeline acceptance test, need measure outer diameter tube usually, most employing mode is that multimetering judges with the mode of obtaining mean value whether pipeline is qualified, and can not realize the continuous coverage to external diameter.
Summary of the invention
In order to overcome above-mentioned weak point of the prior art, the utility model proposes a kind of external diameter continuous meter, solves the problem that can't carry out continuous coverage to outer diameter tube in the pipeline inspection in the prior art.
The utility model is realized through following technical scheme: design, make a kind of external diameter continuous meter, by traversing carriage, traverse measurement unit and the link that is used to be connected said traversing carriage and said traverse measurement unit form; Said traversing carriage is enclosed within on the said fixedly gauge head, and said fixedly gauge head is fixed on the said link; Said traversing carriage comprises upper and lower centering part, and the outer end line of said upper and lower centering part is vertically divided said fixedly gauge head equally.
As the further improvement of the utility model, said upper and lower centering part is last centering guide wheel and following centering guide wheel.
As the further improvement of the utility model, said traverse measurement unit comprises mobile gauge head, reading unit, elastic component and screw mandrel; Said reading unit is positioned on the said mobile gauge head, said being enclosed within on the said screw mandrel, and said elastic component and screw mandrel are positioned at a side of said mobile gauge head and replace said mobile gauge head.
As the further improvement of the utility model, said mobile gauge head and said fixedly gauge head are positioned on the same diameter of a circle line.
Further improvement as the utility model has the hole on the said link.
As the further improvement of the utility model, said reading unit comprises scale mark, electronical reading table and digital display meter.
The beneficial effect of the utility model is: through the external diameter of continuous coverage pipeline, improved the measuring accuracy of outer diameter tube greatly and improved work efficiency.
Description of drawings
Fig. 1 is the instrumentation plan of the utility model external diameter continuous meter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done further to describe.
A kind of external diameter continuous meter, by traversing carriage, traverse measurement unit and the link that is used to be connected said traversing carriage and said traverse measurement unit form; Said traversing carriage is enclosed within on the said fixedly gauge head, and said fixedly gauge head is fixed on the said link; Said traversing carriage comprises upper and lower centering part, and the outer end line of said upper and lower centering part is vertically divided said fixedly gauge head equally.
Said upper and lower centering part is last centering guide wheel and following centering guide wheel.
Said traverse measurement unit comprises mobile gauge head, reading unit, elastic component and screw mandrel; Said reading unit is positioned on the said mobile gauge head, said being enclosed within on the said screw mandrel, and said elastic component and screw mandrel are positioned at a side of said mobile gauge head and replace said mobile gauge head.
Said mobile gauge head and said fixedly gauge head are positioned on the same diameter of a circle line.
Have the hole on the said link.
Said reading unit comprises scale mark, electronical reading table and digital display meter.
In one embodiment, as shown in Figure 1, a kind of external diameter continuous meter, by traversing carriage 2, traverse measurement unit and the link 4 that is used to be connected said traversing carriage 2 and said traverse measurement unit form; Said traversing carriage 2 is enclosed within on the said fixedly gauge head 22, and said fixedly gauge head 22 is fixed on the said link 4; Said traversing carriage 2 comprises upper and lower centering part, and the outer end line of said upper and lower centering part is vertically divided said fixedly gauge head 22 equally, and in one embodiment, this upper and lower centering part is last centering guide wheel 21 and following centering guide wheel 23.
During measurement; Measured piece 1 is put well; Measuring instrument is placed on the measured piece 1, regulates traversing carriage 2 and mobile gauge head 3 then, on the traversing carriage 2 go up centering guide wheel 21 and following centering guide wheel 23 and fixedly gauge head 22 be attached to respectively on the measured piece 1; At this moment, feel relieved on guide wheel 21 and following centering guide wheel 23 and fixing gauge head 22 is respectively three points on the circle and fixedly gauge head 22 and mobile gauge head 3 are diameter of a circles.Regulate the compression spring nut 33 on the traverse measurement unit and the screw mandrel locknut 34 of screwing, owing to compression spring nut 33 slides, in measuring process on screw mandrel 35; If the value of measuring changes, then can show, in the present embodiment through the reading unit; The reading unit is rule 31 and digital display meter 32, wherein is a millimeter reading on the rule, is the decimillimeter reading on the digital display meter 32; Can the different reading unit of conversion according to actual conditions, like rule, digital display meter and electronics indicator gauge etc.
In measuring process, only need the traverse measurement appearance just can accomplish continuous coverage, and can show measurement result continuously, not only convenient directly perceived, and can reduce Measuring Time, practice thrift cost of labor.Not only can be used in above the duct survey, in the measurement of circular device, all can adopt above-mentioned measuring instrument to test.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
