Servo pressurizing based depth measuring mechanism capable of variable pitch adjustment

Abstract

The invention relates to a device for measuring the depth between a differential bearing in an automobile gearbox and the contact surface of a gearbox housing and a dust-proof cover, and specifically relates to a servo pressurizing based depth measuring mechanism capable of variable pitch adjustment. The mechanism comprises a servo pressure measurement portion and a variable pitch adjustment portion. The variable pitch adjustment portion comprises a displacement cylinder, a linear guide rail and a displacement connection board. The servo pressure measurement portion is installed on the displacement connection board and is driven to perform reciprocating motion on the linear guide rail through the displacement cylinder. The servo pressure measurement portion comprises a servo motor, a decelerator, a ball screw, a connection frame, a floating adjustment portion, a pressure sensor, a connection shaft, a displacement sensor, a pressure head and a measurement pressure head. The servo motor is connected with the ball screw through the decelerator. One end of the connection frame is in threaded connection with the ball screw. The other end of the connection frame is successively connected with the floating adjustment portion, the pressure sensor, the connection shaft, the pressure head and the measurement pressure head. The mechanism provided by the invention has the advantages of adjustable measuring pressure, diversified suitable models, reliable work and the like.

Description

technical field [0001] The invention relates to a depth measuring device between a differential gear bearing in an automobile gearbox, a gearbox casing and a dust cover contact surface, in particular to a depth measuring mechanism based on servo pressurization and variable pitch adjustment. Background technique [0002] As the core component that transmits power to the half shafts on both sides and ensures that the half shafts on both sides can rotate at different speeds, the differential widely exists in various types of gearboxes; due to the special functions of the differential, its assembly There are strict requirements. Due to the limitations of the processing technology, it is impossible to ensure that the dust cover above the differential bearing is just against the differential bearing in actual assembly, and corresponding gaskets need to be placed for adjustment, and the thickness of the gasket directly affects the correct operation of the differential. Therefore, ...

Problems solved by technology

These traditional methods are inaccurate and uncontrollable for pressure application, and the traditional method determines the position relative to the transmission input shaft distance of the input torque during measurement. This limits the measurement mechanism to only be applicable to the differential in one type of automobile gearbox. Depth measurement of contact surfaces between bearings and gearbox housings and shields
