Problems solved by technology
[0002] In the field of mechanical processing technology, screw sleeves are common mechanical structural parts, and threads are common connection structures on mechanical parts. In order to ensure the manufacturing accuracy and quality of mechanical parts, after the mechanical structural parts are manufactured and formed, corresponding In the prior art, due to the helical arrangement of the external thread of the screw sleeve, it is very difficult to measure the radial runout of the external thread, and the measurement accuracy is not high. Therefore, it is urgent to develop and design A measuring device specially used for measuring the radial runout of the pitch diameter of the external thread of the screw sleeve

The invention provides a thread sleeve external thread pitch diameter radial run-out measuring device. The device comprises a bottom plate, a vertical supporting plate, a core rod and a U-shaped supporting plate, the lower end of the vertical supporting plate is fixedly connected with the bottom plate; the upper end of the vertical supporting plate is fixedly connected with the supporting plate; the supporting plate is provided with a first supporting arm and a second supporting arm; a dial indicator is fixedly connected to the first supporting arm; the dial indicator comprises a measuring rod, a needle rod is fixedly connected to the second supporting arm, a testing needle capable of sliding up and down in the vertical direction is sleeved with the needle rod, one end of the core rod is fixedly connected with the vertical supporting plate, the other end of the core rod extends outwards in the horizontal direction, and when a threaded sleeve is arranged on the core rod in a sleeving mode, the testing needle is clamped between the external thread of the threaded sleeve and the measuring rod. By adopting the technical scheme of the invention, a corresponding measurement value can beread from the dial indicator by rotating the threaded sleeve around the central axis of the core rod, and various disturbances in an external environment can be avoided by stably supporting the dial indicator, so that the measurement precision is improved.
