Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings, but not as any limitation to the present invention.

[0032] A measuring tool for measuring the diameter of the circumscribed circle of the eye reamer roller, such as figure 1 and figure 2 shown. It includes the lower V-shaped iron 2 and the upper V-shaped iron 3 connected by the bolt 1; in order to facilitate the quick loading and unloading of measuring tools, a gap can be processed on the upper V-shaped iron 3, and the swing bolt can be used to quickly enter the gap, and the lower end of the swing bolt is connected with the The lower V-shaped iron 2 is hinged, and the work of loading and unloading the measuring tool can be completed without completely withdrawing the nut. The center of the top surface of the upper V-shaped iron 3 is provided with a support rod 4. In order to reduce measurement errors, the support rod 4 and the upper V-shaped iron 3 adopt a...

Abstract

The invention discloses a measuring tool and a measuring method for measuring the diameter of the circumscribed circle of the revolving wheel of an eye marker. The measuring tool includes a lower V-shaped iron (2) and an upper V-shaped iron (3) connected by bolts (1); a support rod (4) is provided in the center of the top surface of the upper V-shaped iron, and the support rod is provided with a A measuring seat (5) for axial movement on the rod, at least two positioning nuts (8) are arranged on the supporting rod; a measuring rod (6) is arranged on the measuring seat, and a measuring instrument (7) is arranged on the measuring rod. The invention uses a set of measuring tools to realize the measurement of multiple specifications of series products, replacing hundreds of existing ring gauges. The measurement benchmark coincides with the design benchmark to ensure the coaxiality between the circumcircle of the roller's revolution and the main body, and the measurement accuracy can reach 0.05 mm, which improves the reliability of product quality. The measurement process of the three-roller eye marker in the present invention is simple, accurate, labor-saving and time-saving, and is also applicable to the measurement of the larger diameter of the circumscribed circle of revolution of other planetary rollers.

Description

technical field [0001] The invention relates to a measuring tool and a measuring method for measuring the diameter of the circumscribed circle of an eye reamer roller, belonging to the technical field of product measurement and measuring tools. Background technique [0002] In the process of oil drilling, when encountering hard formations or abrasive rock formations, the wear of the drill bit increases and the diameter becomes smaller, resulting in the drilled wellbore not reaching the standard size, which affects subsequent downhole operations. Usually, the reamer is used to expand the wellbore to meet the standard Well diameter. The three-roller eye marker is a kind of eye reaming tool that is widely used at present. [0003] The main components of the three-roller eye marker are a cylindrical body with a larger diameter in the middle and smaller diameters at both ends and three rollers. There are three grooves evenly distributed along the circumference on the large-diam...
