Problems solved by technology

Since there is a certain gap between the fixture and the fixture base, when the base gauge and the taper gauge are installed separately, since the calibration and measurement are two different installations, the applied pressing force may be inconsistent, resulting in the base gauge calibrated by the base gauge. The end faces of the surface and taper gauges are not at the same position, that is, the calibration process of the base surface gauge introduces a certain error, which has a more serious impact on the measurement results of the larger taper gauge

Abstract

The present invention discloses a long-pipe taper thread measurement device, a taper plug gauge clamp and a taper ring gauge clamp. The measurement device of the long-pipe tape thread comprises a support platform and a measurement mechanism, and also comprises a first support clamp, a second support clamp, a first taper sleeve clamp and a second taper sleeve clamp. A standard is installed on the first taper sleeve clamp and the second tape sleeve clamp, the first taper sleeve clamp is installed on an outer taper thread, and the second taper sleeve clamp is installed on an inner taper thread to allow the standard to fix with the outer taper sleeve thread and the inner taper sleeve thread; and the first support clamp and the second support clamp are installed on the support platform for measurement, and the location of the outer taper thread and the inner taper thread are completed at one time to avoid the installation location error caused by installing the standard at first and then installing the long taper tube. The long-pipe taper thread measurement device can realize measurement through one-time installation, so that the measurement precision of the measurement device is high and the measurement is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of thread measurement, in particular to a measuring device for taper threads of long pipes, a taper plug gauge fixture and a taper ring gauge fixture. Background technique [0002] In petroleum, coal and other industries, there are long drill pipes and oil rods of several meters or even tens of meters. The two ends of the long drill pipes and oil rods have taper threads for connection and sealing. Through thread connection, they can be connected into Hundreds of meters, or even thousands of meters of long pipe, the long pipe has to withstand high temperature and high pressure for a long time when working, that is, the requirements for the taper thread at both ends of the long drill pipe and oil rod are very high, and the taper thread needs to be detected during manufacture and use Comprehensive parameters, such as base diameter, base diameter, base diameter, pitch, pitch cumulative error, tooth angle, tooth ...
