Description
Technical field
The utility model relates to and demarcate internal diameter and outside gauge, the internal diameter of band tapering and the marking apparatus of outside gauge, particularly be the Variable Type Internal and External Foot-Paths Gage Calibrating Apparatus of petroleum casing pipe, oil pipe and the arbitrary cross section inner and outer diameter that has the tapering sealing surface.
Background technology
The external diameter of the external diameter of measurement pipe or internal diameter, tapering pipe or internal diameter are commonly used to compare and measure, promptly, make the higher calibrating block of precision in advance according to the size of drawing, be put on the special measuring tool of a band clock gauge gauge head as measuring basis with this calibrating block, the reading that clock gauge is recorded the result is adjusted to zero-bit, special measuring tool is put on the workpiece to compare and measure again, and the numerical value that reads the clock gauge gauge head is the physical size of workpiece, result and the calibration value that records compared, judge whether workpiece is qualified.
Fig. 1 is prior art is demarcated petroleum casing pipe, oil pipe seal outer diameter gauge with calibrating block a cross-sectional view.As shown in Figure 1, its structure comprises: calibrating block 51 and measurement seal outer diameter gauge 50.There is measurement face 57 at the two ends of calibrating block 51, and the face 58 vertical with measurement face 57 is axial reference fields of calibrating block 51.Measuring seal outer diameter gauge 50 comprises: support 60 and gauge head.There is the gauge head bracing or strutting arrangement at the two ends of support 60 1 sides, and the handle 54 of this gauge fixedly is convenient to operate in its another side.The gauge head bracing or strutting arrangement is support fixation gauge head 56 and the movable gauge head 52 that has clock gauge respectively.The axial reference field 53 of measuring sealing bore gauge 50 is positioned at gauge head one side and relative with calibrating block 51 axial reference fields 58 positions.
The step of demarcating the seal outer diameter gauge with calibrating block 51 by Fig. 1 structure is: at first make and the measure-alike calibrating block 51 of workpiece drawing, make the measurement seal outer diameter gauge 50 that is complementary with calibrating block 51 again.During operation, calibrating block 51 is inserted in measurement seal outer diameter gauge 50 grooves, make 53,58 contacts of above-mentioned two axial reference field, calibrating block 51 does not have in groove and rocks, accurate to guarantee calibrating block 51 measuring positions, rotate the clock gauge gauge head then and look for the flex point of calibrating block 51 measurement faces 57, the flex point reading that clock gauge is demonstrated is adjusted to zero-bit.Again the axial reference field 53 of this measurement seal outer diameter gauge 50 is clung on the location end face of tested petroleum casing pipe, oil pipe, rotating the clock gauge gauge head looks for the flex point of tested petroleum casing pipe, oil pipe external diameter to determine its reading value, two flex point numerical value of calibrating block 51 and petroleum casing pipe, oil pipe are compared, determine whether in the tolerance scope, judge whether petroleum casing pipe, oil pipe be qualified.
