The automatic measuring device for the tight distance of the oil casing coupling includes an automatic loading and unloading mechanism and an automatic measuring mechanism. The automatic feeding mechanism and the automatic measuring structure are connected through a connecting platform; the automatic measuring mechanism includes a base, and a coupling fixing device and The support frame, the detection frame is installed on the support frame, the plug gauge is installed on the detection frame through the connecting shaft, the plug gauge is located above the coupling fixing device, the upper end of the connecting shaft is provided with a pulley, the pulley is connected to the motor through the transmission belt, and the detection machine An execution device is also arranged on the frame, and a displacement sensor is arranged on the execution device. The invention has a high degree of automation, reduces the labor intensity of workers, does not need to perform calculations, is convenient and quick, and can directly measure the close distance between the plug gauge and the coupling after matching, improves the efficiency of detection of the close distance of the coupling, and avoids human factors and environmental factors.

Description

technical field [0001] The invention relates to a tool for measuring the coupling of oil and casing, in particular to an automatic measuring tool for the tight distance of the coupling of oil and casing. Background technique [0002] The tight distance of the oil casing collar reflects the comprehensive influence of the taper, pitch, tooth height, tooth profile angle, pitch diameter and other deviations of the oil casing collar thread, and is a comprehensive parameter of the machining accuracy of the oil casing collar thread Indicators. At present, the detection of the tightness of the oil casing coupling is to manually put the plug gauge into the coupling and then screw it in. When the hand is so tight that the plug gauge can no longer move forward, stop and use the depth gauge to measure the end face of the coupling to the plug gauge. For the axial distance of the end face, after reading the depth gauge data correctly, gently unscrew the plug gauge from the coupling. The w...

[0002] The tight distance of the oil casing collar reflects the comprehensive influence of the taper, pitch, tooth height, tooth profile angle, pitch diameter and other deviations of the oil casing collar thread, and is a comprehensive parameter of the machining accuracy of the oil casing collar thread Indicators. At present, the detection of the tightness of the oil casing coupling is to manually put the plug gauge into the coupling and then screw it in. When the hand is so tight that the plug gauge can no longer move forward, stop and use the depth gauge to measure the end face of the coupling to the plug gauge. For the axial distance of the end face, after reading the data of the depth gauge correctly, gently unscrew the plug gauge from the coupling, the work is labor intensive, the detection efficiency is low, and the tightening force is prone to inconsistency each time, which affects the detection effect
