Abstract

The invention discloses a high-precision shaft diameter measuring device and a measuring method. The device comprises a supporting plate, a servo motor, a double-telecentric lens, a CCD camera and a telecentric parallel light source. A mounting plate is arranged on the upper left portion of the supporting plate. The top end of a threaded rod is connected with an adjusting block. A threaded sleeveis mounted on the outer side of the threaded rod. A connecting block is mounted in the connecting rod. A clamping block is arranged on the right side of the connecting block. An upper pressing block is fixed with the tail end of a fixed rod. A mounting block is connected with the outer side of a lower pressing block. A movable block is arranged at the tail end of a connecting belt. A protective block is mounted on the outer side of the movable block. A connecting plate is fixed with the rear portion of an accommodating plate. A lead screw is connected with the output end of the servo motor. The double-telecentric lens is mounted on the right side of the front portion of a fixed plate. According to the high-precision shaft diameter measuring device, shafts of different sizes can be conveniently fixed; the shafts can be conveniently prevented from falling off; and the measuring precision can be conveniently improved.

Description

technical field [0001] The invention relates to the technical field of shaft diameter measurement, in particular to a high-precision shaft diameter measurement device and a measurement method. Background technique [0002] Shaft parts are one of the accessories often encountered in hardware accessories. They are mainly used to support transmission parts such as gears and pulleys. When using shaft parts, the shaft diameter accuracy of shaft parts directly affects installation and use, so it is necessary to The high-precision shaft diameter measuring device can accurately measure the shaft diameter of shaft parts; [0003] However, the shaft diameter measuring device on the market is inconvenient to fix shafts of different sizes, prevent the shaft from falling, and improve the measurement accuracy. Therefore, we propose a high-precision shaft diameter measuring device to solve the above problems. questions raised in . Contents of the invention [0004] The purpose of the p...
