It measures the internal diameter of casting pipe different parts and reads and record data, eventually by the data and production standard that will be read and record
It compares to determine that casting pipe internal diameter has without acceptance of persons and its oval degree.In this way, just can be obtained in pipe fitting by one-shot measurement
Diameter improves detection efficiency whether in the margin of tolerance.Meanwhile this method can also intuitive judgment pipe fitting internal diameter lose circle where
Circumferential orientation, the mistake circle degree that real-time display respectively loses dot reduce error caused by calculating because of manual measurement without calculating.
In the present embodiment, in order to optimize the structure of cubing to facilitate testing staff's prompt operation, as shown in Fig. 2, excellent
Selection of land, cubing are made of adjustable seats 1, adjusting bolt 2, articulated arm 3 and scalable graduated scale 4；The both ends end face of adjustable seats 1
It is partially recessed inwardly and is formed with threaded hole, the screw rod for adjusting bolt 2 can close connection with corresponding threaded holes and adjust bolt 2
Head is provided with rubber bulb 5；One end of articulated arm 3 is movably riveted on the central point of adjustable seats 1 and makes the another of articulated arm 3
One end can be rotated by the center of circle of movable riveting point；Scalable graduated scale 4 is set in the outside of articulated arm 3 and can be along articulated arm
3 length direction reciprocatingly slides and is fixed by adjusting screw 6, and adjusting screw 6 can determine on scalable graduated scale 4
Position hole is simultaneously rotated to being resisted against on the outer wall of articulated arm 3.In this way, 1 both ends of cubing adjustable seats set the adjusting with rubber bulb 5
Bolt 2 is used to support the inner wall in pipe part, and adjustment activity riveting point is overlapped it with pipe fitting central axis, and will
Cubing ontology is fixed in pipe fitting.And spring is set in shrinkage-rule, for shrinkage-rule to be tensioned, ruler end is kept to connect with pipe fitting inner wall
Touching can show pipe fitting inside radius size by flexible graduated scale in this way when measuring.Then, shrinkage-rule is circumferentially rotated,
Measure the internal diameter of different parts.Meanwhile articulated arm 3 can be facilitated by adjusting 6 fixation of screw according to different cast tubes
The difference of inner diameter size adjusts and fixes position of the scalable graduated scale 4 on the outer wall of articulated arm 3, further expansion inspection
Has applicability.Eventually by the ovality for reading measurement needed for its size fluctuation amount is exactly.Therefore, which can be fast and effective
Intuitively detect that round tube inside diameter has without acceptance of persons and its oval degree.
For the ease of fixed cubing and further accurate detection measurement as a result, preferred steps b includes: by adjustable seats
1 protrudes into from the side opening of casting pipe, and the adjusting bolt 2 by rotating two sides squeezes rubber bulb 5 and stands tightly against
On the inner wall of casting pipe；Also, it should ensure that movable riveting point is overlapped with the central axis of casting pipe after rotation is adjusted.
Likewise, for the ease of adjusting and fixing scalable graduated scale 4 according to the difference of different cast tube inner diameter sizes
Position on the outer wall of articulated arm 3, further expansion cubing applicability, it is preferable that step c includes: to slide on articulated arm 3
Scalable graduated scale 4, adjusting screw 6 is screwed when the end of scalable graduated scale 4 is resisted against on the inner wall of casting pipe can
Flexible graduated scale 4 positions；Then, rotation articulated arm 3 makes scalable 4 circle rotation of graduated scale measure the interior of different parts
Diameter.
When adjustable seats 1 are erected inside casting pipe, further to increase rubber bulb and casting pipe inner wall
Between frictional force, improve cubing it is fixed after stability, it is preferable that the appearance contacted on rubber bulb with casting pipe inner wall
Multiple graininess protrusions are laid on face.
Further, since need to guarantee that adjustment activity riveting point is overlapped it with pipe fitting central axis in the detection process,
It is precisely directed to above-mentioned axial centerline in order to more convenient, is preferably in axial direction set on the screw rod outer wall of adjusting bolt 2
There is length scale.Since one end of articulated arm 3 is movably riveted on the central point of adjustable seats 1, only need adjusting both ends in this way
Notice that the scale for controlling two sides exposing unanimously just can accurately find center and measure when adjusting bolt 2.
In order to improve the mechanical strength of adjustable seats 1, its bending or torsion effect measurement result, preferably adjustable seats are prevented
1 is rectangle or round steel pipe.
In addition, due to cubing measurement when be placed in inside casting pipe, no matter manually go at this time rotation adjust bolt 2 or
It goes rotation all inconvenient using machine tool, positioning can not be quickly completed to go on smoothly monitoring, asked to solve the technology
Topic, the head of preferably adjusting bolt 2 have extended radially outward rotating bar, and one end of rotating bar, which is welded on, to be adjusted on bolt 2, separately
One end is connected with a rotational handle.
In the unarmed rotary motion handle of inspector, it is difficult to since the hot weather centre of the palm has sweat to will lead to hand skidding
It is rotated after holding with a firm grip, in order to avoid the generation of above situation, it is preferable that be equipped at intervals on the outer wall of rotational handle a plurality of anti-skidding convex
Item.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited to above-mentioned realities
The detail in mode is applied, within the scope of the technical concept of the present invention, a variety of letters can be carried out to technical solution of the present invention
Monotropic type, these simple variants all belong to the scope of protection of the present invention.
It is further to note that specific technical features described in the above specific embodiments, in not lance
In the case where shield, can be combined in any appropriate way, in order to avoid unnecessary repetition, the present invention to it is various can
No further explanation will be given for the combination of energy.
In addition, various embodiments of the present invention can be combined randomly, as long as it is without prejudice to originally
The thought of invention, it should also be regarded as the disclosure of the present invention.
