[0009] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0010] A tool for detecting thread coaxiality, such as Figure 1 As shown: it includes a stud screw 1, a conical nut 2, a base 3, a bushing 4, a spring 5, a gasket 6, and a wrench bolt 7; the base 3 is installed with a conical nut 2, the left side of the conical nut 2 is connected to the right side of the bushing 4, the left side of the bushing 4 is connected to the right end of the spring 5, the left end of the spring 5 passes through the gasket 6 and is connected to the left end of the wrench bolt 7, the right end of the wrench bolt 7 passes through the spring 5 and the bushing 4 and is connected to the internal thread on the left side of the conical nut 2, and the internal thread on the right side of the conical nut 2 is connected to the stud screw 1.
[0011] The present invention has two methods of use: The first method: Install the self-locking nut with a closed outer circle on the stud screw 1, manually rotate and tighten the bolt 7, and use a dial indicator to detect the coaxiality of the closed outer circle and the internal thread. At the same time, detect the pressure and consistency of the closing after closing.
[0012] The second method: Replace the stud screw 1 with a threaded sleeve, screw the bolt to be tested into the threaded sleeve, and detect the coaxiality of the polished rod and other parts with the thread.
