Abstract
The utility model relates to a measuring device for special thread torque step depth. The measuring device comprises a positioning rod and a graduated scaleplate, wherein the positioning rod and the graduated scaleplate are connected and vertical to each other; and the measuring device is characterized in that the end part of the graduated scaleplate is provided with a measuring head, and the shape and size of the measuring head are matched with the shape of a special thread torque step. The measuring device has the advantages of simple structure and convenient usage, can measure the depth of the special thread torque step directly by additionally arranging the measuring head matched with the special thread torque step in shape, reduces measuring errors and increases measuring accuracy; and the tip part on the measuring head is designed into an arc shape, the measuring device eliminates the interference point at which the measuring device is in contact with a component during measurement, and is more convenient for the smooth conduct of the measuring operation.
Description
Technical field
The utility model relates to a kind of measurement mechanism, specifically a kind of measurement mechanism of the special thread moment of torsion step degree of depth.
Background technology
Tubing and casing is widely used in the Development and Production of Oil/gas Well, tubing and casing is in processing and manufacturing process, for improving the sealing effectiveness after connecting, need measure the special thread moment of torsion step degree of depth in inner sleeve, be mainly to adopt common pit gauge to the measurement of the special thread moment of torsion step degree of depth at present.As shown in Figure 1 and Figure 2, when measurement, because special thread moment of torsion stepped portions exists a ramp down angle, cannot measure the end position of moment of torsion step with common pit gauge, finally cause the degree of depth of measurement accurate not, thereby have influence on the crudy of product.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of measurement mechanism of the special thread moment of torsion step degree of depth is provided, and it is simple in structure, easy to use, can measure the end position of moment of torsion step, guarantee that measurement result is accurate, improve the crudy of product.
The technical scheme providing according to the utility model: the measurement mechanism of the special thread moment of torsion step degree of depth, comprise backstay and graduated scale, backstay is connected with graduated scale and is mutually vertical, it is characterized in that: described graduated scale end is provided with measuring head, the shape of the geomery of described measuring head and special thread moment of torsion step is suitable.
As further improvement of the utility model, the most advanced and sophisticated position for stretching into special thread moment of torsion stepped ends on described measuring head is made as arc.
As further improvement of the utility model, described backstay is connected by clamping screw with graduated scale.
compared with prior art, advantage is the utility model:the utility model is simple in structure, easy to use, by with the suitable measuring head of the shape that increases special thread moment of torsion step, can directly measure the degree of depth of special thread moment of torsion step, reduce measuring error, raising measuring accuracy.By the most advanced and sophisticated position on measuring head is made as to arc, eliminate the interference point contacting with part while measurement, be more convenient for measuring operation and carry out smoothly.
Accompanying drawing explanation
Fig. 1 is structure and the application schematic diagram of the measurement mechanism of the existing special thread moment of torsion step degree of depth.
Fig. 2 is the A portion enlarged diagram in Fig. 1.
Fig. 3 is structure of the present utility model and application schematic diagram.
Embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in the figure: the measurement mechanism of the special thread moment of torsion step degree of depth in embodiment is mainly made up of backstay 1, graduated scale 2 measuring heads 3 and clamping screw 4.
As shown in Figure 3, described backstay 1 and graduated scale 2 are connected by clamping screw 4 and are mutually vertical, and described graduated scale 2 ends install and measure 3 with screw, and the shape of the geomery of described measuring head 3 and special thread moment of torsion step 5 is suitable.
As shown in Figure 3, in the utility model, the most advanced and sophisticated position for stretching into special thread moment of torsion step 5 ends on described measuring head 3 is made as arc.Can eliminate like this interference point that the utility model contacts with part in the time measuring, be more convenient for measuring operation and carry out smoothly.
When concrete application, graduated scale 2 stretches in tubing and casing 6, the tubing and casing 6 ends backstay 1 that reclines, measuring head 3 snaps in the ramp down angle at special thread moment of torsion step 5 positions, now can directly read depth value from the left side of graduated scale 2, without the computation and measurement error of drawing again, intuitive and convenient.
