In the dial test indicator on holder.
Three groups of support positioning components are uniformly distributed along the circumference.
It is formed with slot hole and threaded hole on the connecting plate.
The beneficial effects of the invention are as follows：
The present invention utilizes compact adjustable mechanical device, is suitable for the line thickness of pipe wall of two kinds of ripple structions of evagination and indent not
The dedicated test of the uniformity can quickly obtain wall unevenness formation value, improve detection efficiency, also be suitable for batch to develop
The automatic special detection device of metaplasia production has established mechanical structure basis.

Specific implementation mode
With reference to the accompanying drawings of the specification and embodiment carries out in detail corrugated pipe wall thickness ununiformity evenness detection device of the present invention
Explanation：
As shown in Figure 1 and 2, a kind of corrugated pipe wall thickness ununiformity evenness detection device, including supporting and positioning mechanism 1 and measuring machine
Structure 2；The supporting and positioning mechanism 1 includes bottom plate 3 and three groups of support positioning components 4 being set on bottom plate 3；The support positioning
Component 4 includes the connecting plate 5 being fixedly connected with bottom plate 3 and the support shaft 6 being installed on connecting plate 5, and 6 top of support shaft is equipped with
Rectangular positioning plate 7, supporting rod 8 is equipped in 7 one side wall of rectangular positioning plate, and 7 top of rectangular positioning plate is equipped with round positioning plate
9；The measuring mechanism 2 includes holder 11 and the dial test indicator 10 being installed on holder 11.
Three groups of support positioning components 4 are uniformly distributed along the circumference.
Slot hole 12 and threaded hole 13 are formed on the connecting plate 5.
Slot hole 12 is that adjustment for convenience supports position of the positioning component 4 on bottom plate 3, waits for supporting positioning components by three
4 adjustment positions touch the wave bottom of bellows 14 to be measured to its circle positioning plate 9, and on 14 concentric circles of bellows
When uniformly distributed in hexagonal angle, three support positioning components 4 are fixed with bottom plate 3 with screw.The 13 place end of threaded hole of connecting plate 5 is equal
It can be positioned when staggered relatively and place the measurement of inner concave shape bellows, the 13 place end of threaded hole of connecting plate 5 can determine when placing opposite to each other
It places male type bellows and measures in position.The threaded hole 13 of connecting plate 5 and one section of screw thread axis connection of 6 bottom of support shaft, support shaft 6
The rectangular positioning plate 7 of optical axis section housing on top is locked after adjusting good position with jackscrew, and 7 side of rectangular positioning plate is threaded hole
To install supporting rod 8, for round positioning plate 9 above rectangular positioning plate 7, there is threaded hole at center, is mounted on the top spiral shell of support shaft 6
Line section.
The support shaft 6 is commercially available part, can adjust height so that is on the downside of the ripple of bellows 14 to be measured same
On one horizontal plane.
The present invention the course of work be：
Measured workpiece bellows 14 is placed, adjusts the height of support shaft 6 so as to be measured wave of the frame at 8 bulb of supporting rod
It is in same level on the downside of the ripple of line pipe 14.
As shown in figure 3, wave bottom is tightly attached to the side wall of round positioning plate 9, the probe location of dial test indicator 10 is adjusted,
Its is set to contact symmetrical one side on the downside of ripple, manual rotation bellows 14 to be measured, the greatest measurement of dial test indicator 10 and most
The difference of small measured value is the wall unevenness evenness of 14 corrugated sidewalls of bellows.As shown in figure 4, adjusting dial test indicator 10 again
Probe location, make its contact the symmetrical one side of wave bottom, manual rotation bellows 12 to be measured, the maximum of dial test indicator 10
The difference of measured value and minimum measured value is the wall unevenness evenness of 14 wave bottom of bellows.
