Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The utility model is a kind of main pump bolt elongate flowmeter auxiliary calibrating tooling, as shown in figs 1 to 6 comprising
Steel pipe 2, the upper and lower ends of steel pipe 2 are respectively welded the first irony square 1 and the second irony square 3, in the second irony square 3
Between be equipped with diameter be 30mm circular hole 4.The center line of first irony square 1, steel pipe 2 and the second irony square 3 is in same straight line
On.The contact surface of first irony square 1 and measuring instrument bar portion tip contact is polished surface；Second irony square 3 and measurement
The contact surface position of instrument is polished surface.
First irony square 1, steel pipe 2 and the second irony square 3 are all made of stainless steel material.Measuring instrument is before use, can
Measuring instrument is stored in tooling and is protected, instrument handle nature, can also with casual inspection measuring instrument whether
There are problems.
The different measurement elongation instrument that measuring instrument damage can occur in measurement process or more renew for main pump bolt
Thus device is once examined and determine the data validity of measurement and measuring tool situation of change.
In the assembling process of the utility model tooling, two pieces of irony squares (the first irony square 1 and the second irony are selected
Square 3) and one section of steel pipe 2；The both ends port of steel pipe 2 is smooth, and subject to length of the length according to measuring instrument bar portion, deviation exists
Within ± 2mm；The diameter that spuds in one piece of irony square (i.e. the second irony square 3) wherein is the circular hole 4 of 30mm.By two
Square is welded to connect with steel pipe both ends, guarantees the center of three components on same center line.It, will after being finally completed
It is finished in tooling with the contact surface of instrument contacts, the side of the irony square with circular hole 4 is connect with steel pipe 2, the irony
Polished surface (flatness≤0.02mm) is processed into the other side of square, and the contact surface that another irony square is contacted with steel pipe 2 exists
It is also processed into polished surface (flatness≤0.02mm) before welding, guarantees that polished surface is vertical with the center of three components.Two
Irony square before welding can also simultaneous processing at polished surface.
In prefabrication process, one of face of the first irony square 1 is finished, then by the polished surface with
The center of one end progress welding procedure of steel pipe 2, the first irony square 1 and steel pipe 2 is on the same line.Again by the second irony side
One of plane of block 3 and the other end of steel pipe 2 are welded, and guarantee three (i.e. the first irony square 1, steel pipe 2 and the
Two irony squares 3) center line on the same line, when welding, is controlled, and prevents welding from causing big deflection.Check the
The flatness at the back side of two irony squares, 3 weld side finishes the plane if it is greater than 0.02mm, guarantees finishing
Plane and the first irony square 1, steel pipe 2 and the second irony square 3 central axis.
After the completion of tooling is prefabricated, before carrying out bolt tension at the scene, tooling is vertically disposed in now together with measuring instrument
Tooling is simultaneously fixed in field.
The size of first irony square 1, steel pipe 2 and the second irony square 3 is according to the size of bolt elongate measurement instrument
Scene is made, and the length and wide size of the first irony square 1 and the length of the second irony square 3 and wide size are all larger than
Measuring instrument sucker size 20mm；The length dimension of steel pipe 2 and with 4 irony square of circular hole (i.e. the second irony square 3) thickness gauge
The sum of very little length than measuring instrument measurement bar part it is 5mm long or more than, but overall length dimension (the i.e. length dimension of steel pipe 2
With with the sum of 4 irony square thickness of circular hole) be less than measuring instrument measurement bar part length and its maximum measure size it
With.
Measuring instrument is before use, first measure the auxiliary mould of the utility model, and one group of data of record are as former
Beginning data；It is first measured before measurement every time later.
In the construction process, when measuring instrument measurement front and back data have dissatisfied deviation, the measuring instrument more renewed is carried out
Measurement compares, and examines and determine actual elongation data.
The utility model can examine and determine the validity of the data before and after the measurement of measuring instrument in use；It can also pass through
Data after heating several times are checked, and are provided comparison when the measuring instrument of replacement different model measures in the construction process and are changed
The foundation of calculation.
