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.
