Detailed Description
Embodiments of the present invention are further described with reference to fig. 1 to 5.
A sphere center measuring device comprises a base 1, wherein the center of the base 1 is arranged on a sleeve column 2, a circular groove 20 is arranged in the sleeve column 2, an extension rod 21 in threaded fit is inserted in the circular groove 20, an installation circular groove 2010, a first circular groove 11 and a second circular groove 12 are sequentially sleeved along the circumference of the sleeve column 2, five strip-shaped grooves 13 distributed at intervals are arranged between the installation circular groove 2010 and the second circular groove 12, the strip-shaped grooves 13 are communicated with the installation circular groove 2010, the first circular groove 11 and the second circular groove 12, a sliding block 3 is arranged at the joint of the strip-shaped grooves 13 and the installation circular groove 2010, sleeve pieces 4 are arranged on the sliding block 3, adjacent sleeve pieces 4 are abutted to form a circular sleeve 5, a space between the circular sleeve 5 and the sleeve column 2 is a storage cavity 6, the sliding block 3 is arranged in the strip-shaped grooves 13 in sliding fit, inner grooves 30 are arranged at two ends of the sliding block 3, and a retainer 31 is inserted in the inner groove 30, a spring 32 is arranged between the stop piece 31 and the bottom wall of the inner groove 30, the spring 32 drives a part of the stop piece 31 to slide out of the inner groove 30, and the longitudinal section of the sliding block 3 is larger than that of the installation circular groove 2010, the first circular groove 11 and the second circular groove 12.
