Alignment line, be additionally provided with Alignment window in amount of elasticity on piece, alignment line is distributed in the both sides of Alignment window.
In the present invention, survey tool is cut using steel disc, is reused laser processing scale and is obtained.Application method is to incite somebody to action
Amount of elasticity piece, which is rolled, to be inserted into locating slot, is blocked amount of elasticity piece by locating groove, is put into pipe, allows and measure piece nature bullet
It opens, is adjacent to wave crest in helix tube, whether the alignment line for observing Alignment window has been aligned, and is read by scale and obtains mean inside diameter
Dimension data.Using the elasticity of amount of elasticity piece, so that amount of elasticity piece is adjacent to the interior wave crest of more than two helical corrugations, pass through alignment
Line and locating slot guaranteed discharge piece do not tilt to obtain accurately mean inside diameter data, and the reading of amount piece scale can pass through circumference
Long formula scales obtain.
Further, the graduation mark and alignment line are arranged in parallel.
Preferably, the midpoint of the reading window and the connecting line at the midpoint of Alignment window are vertical with graduation mark.
When reading window is disposed adjacent with Alignment window, when amount of elasticity piece is rolled into circular configuration, reading window is located at Alignment window
Same direction, convenient for reading and observation.
Preferably, the width value of the locating groove is equal to the thickness value of amount of elasticity piece or the width of locating groove
Angle value is more than 0.2 ~ 2mm of the thickness value of amount of elasticity piece.
Preferably, the amount of elasticity piece is rectangle structure.
Preferably, the amount of elasticity piece is elastic steel sheet.Elastic steel sheet can realize curling, but in length direction
On will not deform upon, keep measurement more accurate.
Compared with prior art, advantageous effect is：It is provided by the invention a kind of average for measuring helical corrugation type tubing
The survey tool of internal diameter, survey tool is simple and reasonable, can accurately measure being averaged for helicon pipe material product and its mold
Internal diameter, processing cost is low, easy to use, adjusts size after measurement rapidly, improves mating qualification rate, greatly reduces the wave of material
Take, save cost, implementation is extremely strong.

Fig. 1 is overall structure of the present invention.
Fig. 2 is the enlarged diagram of part A in Fig. 1 of the present invention.
Fig. 3 is use state diagram of the present invention.
Specific implementation mode
The attached figures are only used for illustrative purposes and cannot be understood as limitating the patent；It is attached in order to more preferably illustrate the present embodiment
Scheme certain components to have omission, zoom in or out, does not represent the size of actual product；To those skilled in the art,
The omitting of some known structures and their instructions in the attached drawings are understandable.Being given for example only property of position relationship described in attached drawing
Illustrate, should not be understood as the limitation to this patent.
As shown in Figure 1 to Figure 3, a kind of survey tool for measuring helical corrugation type tubing mean inside diameter, including elasticity
Piece 1 is measured, locating groove 2, when amount of elasticity piece 1 is rolled into circular configuration, the side of amount of elasticity piece 1 are equipped at the both ends of amount of elasticity piece 1
Edge sticks into locating groove 2, and can be slided in locating groove 2；It is equipped with graduation mark 3 along 1 length direction of amount of elasticity piece,
One end of amount of elasticity piece 1 is equipped with reading window 4；It is equipped with a plurality of alignment line 5 being mutually parallel along 1 length direction of amount of elasticity piece,
Alignment window 6 is additionally provided on amount of elasticity piece 1, alignment line 5 is distributed in the both sides of Alignment window 6.
Specifically, the graduation mark 3 and alignment line 5 are arranged in parallel, read midpoint and the Alignment window 6 of window 4
Midpoint connecting line it is vertical with graduation mark 3.It is disposed adjacent with Alignment window 6 when reading window 4, when amount of elasticity piece 1 is rolled into circle
When shape structure, reading window 4 is located at same direction with Alignment window 6, convenient for reading and observation.
Wherein, the width value for the thickness value or locating groove 2 that the width value of locating groove 2 is equal to amount of elasticity piece 1 is more than bullet
0.2 ~ 2mm of the thickness value of property amount piece 1.
In addition, amount of elasticity piece 1 is rectangle structure, and it is elastic steel sheet, elastic steel sheet can realize curling, but in length
It will not be deformed upon on direction, keep measurement more accurate.
In the present invention, survey tool is cut using steel disc, is reused laser processing scale and is obtained.Application method is：Such as
Shown in Fig. 3, amount of elasticity piece 1 is rolled and is inserted into locating slot, amount of elasticity piece 1 is blocked by locating groove 2, puts into pipe, allows
It measures piece to flick naturally, is adjacent to wave crest in helix tube 7, whether the alignment line 5 of observation Alignment window 6 has been aligned, and passes through scale
It reads and obtains mean inside diameter dimension data.Using the elasticity of amount of elasticity piece 1, amount of elasticity piece 1 is made to be adjacent to more than two helicons
The interior wave crest of line does not tilt to obtain accurately mean inside diameter data, amount a moment by alignment line 5 and locating slot guaranteed discharge piece
The reading of degree can be obtained by circumference formula scales.
The present invention is used in helical bellows production and its manufacture of mold, is measured the mean inside diameter of interior wave crest, is convenient for
Product size is adjusted and checked when production.Due to the particularity of spiral corrugation, interior wave crest is not in same vertical direction, very
More survey tools all can not in helical bellows wave crest measure, obtain accurate wave crest average inner and outer diameter parameter,
