Embodiment Construction

[0013] refer to figure 1 , a measuring tool for spherical hole radius of the present invention, including measuring anvil 1, dial indicator 2, measuring head 3 and measuring rod 4. The anvil 1 is provided with a through hole, and the through hole is arranged along the axial direction of the anvil 1 . One end of the measuring anvil 1 is connected with the dial gauge 2, and the other end of the measuring anvil 1 has a flange 1a, and the flange 1a extends radially of the measuring anvil. The probe 3 of the dial indicator 2 extends into the through hole on the anvil 1 . One end of the measuring rod 4 extends into the through hole of the measuring anvil 1 and is connected with the measuring head 3. A sleeve 5 is arranged in the through hole of the measuring anvil 1, and the measuring rod 4 is slidably fitted with the sleeve 5. A sleeve increases the precision of the rod movement. The circumferential surface of the measuring anvil 1 is provided with a threaded hole, and one end o...

Abstract

The invention relates to a measuring tool for spherical hole radius. The tool comprises a measuring anvil, a dial indicator, a measuring head, and a measuring rod. The measuring anvil is provided with a hole. The hole is arranged along the axial direction of the measuring anvil. One end of the measuring anvil is connected with the dial indicator, and the other end of the measuring anvil is a flange. The flange extends to the radial direction of the measuring anvil. The measuring head of the dial indicator extends into the hole on the measuring anvil. One end of the measuring rod extends into the hole of the measuring anvil and is connected with the measuring head. The other end of the measuring rod out of the hole is provided with a radial bulge. The radius of the radial flange is smaller than the radius of the flange on the measuring anvil. The tool can rapidly measure the radius and the deviation of a sphere after a workpiece is processed, so as to determine whether the workpiece is qualified.

Description

technical field [0001] The invention relates to a measuring tool for spherical hole radius. Background technique [0002] At present, the measurement of the radius of the inner and outer circular arcs and spherical surfaces of damaged and incomplete parts is usually obtained by calculating the chord length and chord height of the measured arc. Due to the limitation of measuring tools and means, the measured chord length, chord height data and actual size often deviate, which affects the accuracy of the final radius calculation results and affects the part mapping. Contents of the invention [0003] The main purpose of the present invention is to provide a measuring tool for the radius of a spherical hole, which can quickly measure the radius and deviation of the spherical surface after the workpiece is processed, so as to determine whether the workpiece is qualified. [0004] A measuring tool for the radius of a spherical hole, including an anvil, a dial indicator, a meas...
