Description
Technical field
The utility model is related to examine detection technique field, especially a kind of round tube inner wall apparatus for detecting diameter.
Background technology
Currently, circle pipe part is after processing is completed, need to be detected its inner wall, whether consistent, be if detecting its internal diameter
No the case where there are reducings.Since there are currently no dedicated detection instrument, testing staff can only be with tools such as vernier calipers to circle
Inside pipe wall edge is detected, especially when the length of pipe is longer, in the middle part of internal diameter situation cannot measure, therefore meeting
Cause test result inaccurate, is susceptible to erroneous judgement, substandard product is caused to come into the market.
Utility model content
The purpose of this utility model is that in place of making up the deficiencies in the prior art, provide a kind of reasonable design, it is simple in structure,
It is easy to use, the round tube inner wall apparatus for detecting diameter of accuracy in detection can be improved.
The purpose of this utility model is realized by following technological means：
A kind of round tube inner wall apparatus for detecting diameter, it is characterised in that：Including bottom plate, fixed seat, side shield, spring pocket, arc
A fixed seat is installed in the upper surface of shape scale plate and pull rod, bottom plate, and a mounting groove is made in the fixed seat, on a fixed seat left side
One vertical side shield is installed, the upper surface of the side shield is higher than the bottom surface of mounting groove, on the fixed seat right side on the bottom plate of side
The upper surface of side is installed by one pressing plate；Spring pocket includes two symmetrically arranged supporting blocks, and the inside of two supporting blocks is by bullet
Spring connects, which connects sensor, and cambered surface is made in the outer surface of two supporting blocks, and the rear right of each supporting block is equal
A graduated arc is connected, scale is formed on the graduated arc, the left side of upper support block connects a pull rod.
Moreover, the mounting groove is V-shaped groove, arc is made in the lower surface of pressing plate, and the both ends of the pressing plate pass through jackscrew
In fixed seat.
Moreover, being co-axially mounted a handle on the pull rod.
Moreover, the sensor is pressure sensor, a display instrument is connected.
The advantages of the utility model and good effect are：
1, pipe can be fixed on the positioning in the fixed seat of the present apparatus, side shield and pressing plate, and spring pocket can be to circle
Inside pipe wall measures, and the measurement method is simple and convenient, and measurement result is accurate.In addition, display instrument can directly display numerical value, lead to
Cross whether observation numerical value changes, you can judge whether round tube inside diameter changes, which is simple and clear clear, it is not necessary to use slide calliper rule
It measures, calculate, compare.
2, graduated arc is arranged at spring pocket rear in the present apparatus, and testing staff can sentence according to the scale on graduated arc
Break and the position that internal diameter changes.
3, the spring pocket of the present apparatus includes two symmetrically arranged supporting blocks, and the inside of two supporting blocks is connected by spring
It connects, cambered surface is made in the outer surface of two supporting blocks, therefore this spring pocket is suitble in the pipe progress to different-diameter (specification)
Diameter measures, applied widely.
4, the utility model is a kind of reasonable design, the circle that simple in structure, easy to use, specificity is strong, manufacturing cost is low
Inside pipe wall apparatus for detecting diameter can reduce detection difficulty using the present apparatus, quickening detection speed, improve the accurate of measurement result
Property.In addition, the present apparatus is applied widely, it is suitble to carry out internal diameter measurement to the pipe of different-diameter (specification).

Specific implementation mode
Embodiment of the utility model will be described in detail below with reference to the attached drawings；It should be noted that the present embodiment is narrative
, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of round tube inner wall apparatus for detecting diameter, including bottom plate 1, fixed seat 3, side shield 2, spring pocket, graduated arc
11 and pull rod 7, a fixed seat is installed in the upper surface of bottom plate, a mounting groove is made in the fixed seat, on the right side of fixed seat
Upper surface is installed by one pressing plate 4.Mounting groove is V-shaped groove 13, and arc is made in the lower surface of pressing plate, and the both ends of the pressing plate pass through top
Silk 5 is mounted in fixed seat.
One vertical side shield is installed on the bottom plate on the left of fixed seat, the upper surface of the side shield is higher than mounting groove
Bottom surface is usually located at the height of mounting groove half.Spring pocket includes two symmetrically arranged supporting blocks 8, two supporting blocks
Inside connected by spring 10, the spring connect sensor 9, the sensor be pressure sensor, be connected to the end of spring,
And the pressure sensor connects display instrument.Cambered surface is made in the outer surface of two supporting blocks, and the right side of each supporting block is equal
A graduated arc is connected, scale 12 is formed on the graduated arc, the left side of upper support block connects a pull rod, the drawing
A handle 6 is co-axially mounted on bar.
The application method of the utility model is：
First, spring is set on the inside of the end of pipe to be detected, then pipe is placed on to the V-shaped groove of fixed seat
Interior, the side shield on the left of use positions the end face of pipe, and the pressing plate on the right side of use fastens pipe.Pull rod is finally pulled, spring is made
Set passes through inside pipe, and when round tube inside diameter is inconsistent, display instrument numerical value can change.At this point, testing staff can root
The position that internal diameter changes is marked out according to the scale on graduated arc.
