Problems solved by technology

Since there are many kinds of one-way meters, it is necessary to produce a variety of devices for calibrating the one-way meters at the same time, which leads to the necessity of having a variety of one-way meters and corresponding calibration devices when measuring pipes, which is even more inconvenient. The proofreading devices of the same kind of one-way meters produced by different companies cannot be used universally, which not only causes inconvenience in work, reduces efficiency, but also causes great waste and increases the cost of various enterprises. How to solve the above-mentioned defects is a problem. Urgent problems

Abstract

The invention discloses an apparatus suitable for accuracy calibration of multiple-pipe material measuring one-way instrument. A high precision workbench 2 is provided on a base plate, one end of the workbench is provided with a universal fixture 3, an adjusting rack 5 arranging a standard displacement apparatus is provided on an appropriate position of a bar-shaped slot 4 of the workbench 2, a conical gauge chucking tool 6 is provided on the base plate at one side of the workbench 2. The invention can calibrate one-way instrument of each country, be used for the steel tube producing enterprise, the oil field mechanical manufacturing enterprise, the pipe material quality detection department and the pipe material using unit, also can be used as standard transferring means of country and locality metering departments.

Description

Technical field: [0001] The invention relates to a calibration device, in particular to a device for precision calibration of various individual instruments involved in the petroleum industry. Background technique: [0002] Petroleum drilling is a high-cost industry. The drill pipe, casing and oil pipe widely used in its equipment are all made of a special threaded pipe about 10 meters long, and they are basically connected by threads. The thread pitch diameter, taper, pitch, tooth profile angle, tooth height and other parameters of the above-mentioned threads must meet the specified processing accuracy, otherwise the connection quality and service life will be affected in a complex use environment, and production accidents will occur in severe cases. In order to accurately measure various parameters of the pipe thread, a variety of one-way meters are designed to measure a single parameter. At present, there are many manufacturers of one-way meters, such as Hanzhong Wanmu In...
