Abstract

The invention relates to a gear internal diameter measurement mechanism based on self-centering and a measurement method thereof. The measurement mechanism comprises a centering driving portion, a passive rotation measuring portion and an equipment main body portion, wherein a body and a passive rotation sleeve are respectively mounted on a platen, the body is provided with a cylinder, a piston ofthe cylinder is connected with a lifting sliding table, a rotation fixing sleeve is mounted on the lifting sliding table, a power source is mounted on the rotation fixing sleeve through a fixing support, a rotation shaft is rotatably mounted on the rotation fixing sleeve, one end is connected with an output end of the power source, the other end is connected with a positioning top tip, a rotationdisc and a rotation seat are arranged below the positioning top tip, the rotation seat is rotatably mounted on the passive rotation sleeve, the rotation disc is mounted on the rotation seat and is used for carrying a to-be-measured gear, and a gauge block type displacement sensor is arranged in the rotation seat and is mounted on the passive rotation sleeve through a sensor support. The measurement mechanism is advantaged in that automatic centering, active pressure driving, passive rotation and dynamic measurement are realized, the measurement mechanism is suitable for measuring gears in multiple internal diameter dimensions, measurement precision is high, and work reliability is realized.

Description

technical field [0001] The invention relates to a measuring device for the inner diameter of each gear driven gear of an output shaft in a gearbox, in particular to a gear inner diameter measuring mechanism based on self-centering and a measuring method thereof. Background technique [0002] The key to normal and safe driving of a car lies in the normal operation of the gearbox, and the core of the gearbox lies in the correct meshing of the shafting. The output shaft of the gearbox is one of the core components of the automobile gearbox, and it is also one of the most important components in the composition of the automobile. Due to the special importance of the output to the transmission, there are strict requirements on the assembly of the upper driven gears and shaft sections. The precise assembly of each gear on the output shaft directly affects the overall quality of the gearbox, and the core of accurate assembly lies in the precise fit of the inner diameter of the gea...
