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

This invention discloses a measuring tool and measuring method for measuring revolution excircle of a roller of a reaming device. The measuring tool comprises a lower V-shaped iron (2) and an upper V-shaped iron which are connected through a bolt; the center of the top surface of the upper V-shaped iron is provided with a supporting rod; a measurement seat (5) which can be moved axially on the supporting rod is positioned on the supporting rod; at least two nuts are arranged on the supporting rod; a measurement rod (6) is arranged on the measurement seat; a measurement meter is positioned on the measurement rod. The invention can perform measurement on a series of product with various specifications through one set of measurement tools and replaces existing hundreds of ring gauges. That the measurement standard is relatively matched with the design standard can guarantee the coaxiality between the roller revolution excircle and a main body, and the measurement accuracy can be 0.05 millimeter and the product quality reliability can be increased. The operation for measuring the three-roller reaming device is simple, accurate, labor-saving, and time-saving, and is applicable to measuring the relatively large diameter of the revolution excircle of other 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...
