Measuring Mechanism for Tile Expansion Applied in Assembly Line of Automobile Main Reducer

Abstract

The invention discloses a cover expansion quantity measuring mechanism applied to an automobile main reducing gear combined assembly line. The cover expansion quantity measuring mechanism is characterized in that a probe is fixedly connected to the front end of a linear axle, the linear axle is supported on a base in a clearance fit mode, a check block is fixed to the middle of the linear axle, a reset spring is arranged between the check block and a tail-board of the base, and the check block protrudes and extends upward in the radial direction of the linear axle; a displacement sensor is arranged on the tail-board of the base in the direction parallel to the axis of the linear axle, wherein a measuring head of the displacement sensor abuts against the check block so as to receive the displacement, transmitted by the check block, of the probe; the probe abuts against a cover and is used for detecting and sensing the expansion quantity of the cover in the assembly process of a main reducing gear. According to the cover expansion quantity measuring mechanism applied to the automobile main reducing gear combined assembly line, high-precision measurement of a small expansion quantity of the cover when adjustment knurled nuts at the two ends of the main reducing gear are screwed up can be realized.

Description

technical field [0001] The invention relates to the gear side clearance adjustment of the assembly line of the main reducer of an automobile and the tile cover expansion measurement mechanism of a measuring machine, more specifically a mechanism for measuring the counterpoint expansion displacement of the tile cover caused by tightening the flower nut. Background technique [0002] The main reduction assembly is an important part of the automobile transmission system. It converts the rotation of the output shaft of the automobile gearbox into the rotation of the half shaft and the wheel through a pair of bevel gears. The main reduction assembly has a pair of bevel gears, a differential And the corresponding supporting bearings can decelerate and increase the torque transmitted by the transmission shaft and play a differential role on the wheels on both sides. The differential is fixedly connected with the driven gear in a pair of bevel gears, and they are supported by two ta...

AI Technical Summary

Problems solved by technology

During the tightening process of the flower nut, there is a small displacement of the tile cover relative to the bearing seat, that is, the expansion. So far, there has been no public report on the relevant device for automatic measurement of the expansion.
