According to the technical scheme of the utility model, the measuring instrument for the external thread sealing surface of the oil casing comprises a measuring stand and a dial indicator and is characterized in that the measuring stand comprises a stand body; a first support seat vertical to the stand body is arranged at one end of the stand body; a second detachable support seat vertical to the stand body is arranged at the other end of the stand body; a first measuring contact is fixedly arranged on the first support seat; the second support seat is provided with a radial hole; a bracket passing through the radial hole is fixedly arranged in the radial hole; the dial indicator is fixedly arranged at the outer end of the bracket; a second measuring contact is fixedly arranged at the inner end of the bracket; the distance between the first measuring contact and the upper end face of the stand body is 3-5mm; and the center line of the first measuring contact is in parallel with the stand body. The utility model has the advantages of favorable stability and high precision, is simple for operation and convenient for use and effectively solves the measurement for the distance between the non-planes on the external diameters.

Description

A kind of tubing and casing external thread sealing surface measuring instrument
Technical field
The utility model relates to a kind of simple measurer of tubing and casing, and especially a kind of tubing and casing external thread sealing surface measuring instrument belongs to petroleum industry tubing and casing external thread sealing surface and detects use.
Background technology
Along with economic development, people's living standard quality is in continuous improve, demand to the energy is increasing, the quality requirements of production and processing product is more and more higher, external thread sealing surface measuring instrument is the measurement of better way solution oil pipe thread sealing surface diameter effectively, double thread processing detects and has improved efficient, can effectively solve the difficulty that the measurement of sealing surface non-parallel planes brings.It is to be reference plane with the pipe thread end, and support is installed dial gauge, the dial gauge maximum turning point of searching that slides on sealing surface then, reading numerical values.
Summary of the invention
The purpose of this utility model provides a kind of survey instrument of simple and easy reliable measurements sealing surface diameter, and is simple in structure, uses easy to operately, can effectively improve checkability, guarantees the daily control of product quality, precision height, working stability.
According to the technical solution of the utility model, a kind of tubing and casing external thread sealing surface measuring instrument, comprise measurement bay and dial gauge, it is characterized in that: described measurement bay comprises support body, at an end setting of support body first bearing, at the other end setting of support body dismountable second bearing perpendicular to support body perpendicular to support body; Fixedly install first measuring contacts on described first bearing; On described second bearing radial hole is set; The support of radial hole is passed in the setting of described radial hole internal fixation; The outer end of described support fixedly installs dial gauge, and the inner of support fixedly installs second measuring contacts; Described first measuring contacts is apart from the upper surface 3mm-5mm of support body, and the center line of first measuring contacts is parallel with support body.
Described second measuring contacts is positioned at the inboard of second bearing; Described dial gauge is positioned at the outside of second bearing; The center line of the center line of described first measuring contacts and second measuring contacts is located along the same line.
Between described first measuring contacts and second measuring contacts, the datum length calibrating block is set.
This utility model has the following advantages:
1, adopts fixed support to carry out a contact and can effectively solve the measurement of distance between the non-parallel face on the external diameter according to fixed contact;
2, efficiently solve the high-precision requirement of product;
3, this measuring instrument is to compare and measure, and calibrates then with standard size and measures good stability;
4, this measuring instrument is simple and reliable for structure, and is easy to maintenance, easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As shown in Figure 1, a kind of tubing and casing external thread sealing surface measuring instrument, a kind of tubing and casing external thread sealing surface measuring instrument, comprise measurement bay and dial gauge 4, it is characterized in that: described measurement bay comprises support body 1, at an end setting of support body 1 first bearing 2, at the other end setting of support body 1 dismountable second bearing 3 perpendicular to support body 1 perpendicular to support body 1; Fixedly install first measuring contacts 6 on described first bearing 2; On described second bearing 3 radial hole is set; The support 5 of radial hole is passed in the setting of described radial hole internal fixation; The outer end of described support 5 fixedly installs dial gauge 4, and the inner of support 5 fixedly installs second measuring contacts 8; Described first measuring contacts 6 is apart from the upper surface 3mm-5mm of support body 1, and the center line of first measuring contacts 6 is parallel with support body 1.
Described second measuring contacts 8 is positioned at the inboard of second bearing 3; Described dial gauge 4 is positioned at the outside of second bearing 3; The center line of the center line of described first measuring contacts 6 and second measuring contacts 8 is located along the same line; Between described first measuring contacts 6 and second measuring contacts 8, datum length calibrating block 7 is set.
During measurement, calibrate with datum length calibrating block 7 earlier, with dial gauge zeroing back locking dial gauge panel lock screw.Then first measuring contacts 6 is contacted petroleum thread end sealing face with second measuring contacts 8, rotate support body 1 gently, the reading when reading the maximum turning point of dial gauge 4, the standard size that adds datum length calibrating block 7 is exactly the diameter of sealing surface.
The utility model is simple to operate, and is easy to use, good stability, and the precision height efficiently solves the measurement of distance between the on-plane surface on the external diameter.
