Automatic and precise measuring machine for tapered bearing shims

Abstract

The invention relates to an automatic accurate measuring machine for a cone bearing gasket. The automatic accurate measuring machine comprises a lifting machine head, an off-shell measuring mechanism,a changing-shell measuring mechanism and a rotary simulation mechanism, wherein the off-shell measuring mechanism comprises a loading cylinder, an off-shell measuring plate and a cone bearing outer ring measuring head, the off-shell measuring plate is mounted on the lifting machine head in a floating mode, the cone bearing outer ring measuring head is driven to realize lifting through the loadingcylinder and presses against a cone bearing outer ring on an off shell during measurement, the changing-shell measuring mechanism comprises a measuring cylinder, a guide shaft, a changing-shell measuring plate and a deep hole measuring head, the changing-shell measuring plate is mounted on the lifting machine head in a floating mode, a lower end of the guide shaft penetrates through the changing-shell measuring plate, is then connected with the deep hole measuring head and is lifted through the measuring cylinder, the deep hole measuring head stretches into a to-be-measured hole during measurement when a measuring pressure plate on the guide shaft presses a displacement sensor, and the rotary simulation mechanism used for driving a differential mechanism to rotate is arranged below the lifting machine head. The automatic accurate measuring machine is advantaged in that parameters of the cone bearing gasket can be accurately measured, and actual conditions can be simulated during measurement.

Description

technical field [0001] The invention relates to a measuring device for vehicle transmission accessories, in particular to an automatic and precise measuring machine for tapered bearing pads. Background technique [0002] As an important part of the vehicle transmission, the cone bearing plays an important role in the speed change rotation of the shaft teeth in the operation of the transmission. In the process of assembling the vehicle transmission, the measurement of the thickness of the tapered bearing gasket is very important, and there are strict requirements on the measurement accuracy of the thickness of the tapered bearing gasket in the assembly tooling of the transmission assembly. In the measurement process, it is necessary to ensure the position accuracy of the tapered bearing and the end face of the housing, and at the same time to ensure that the measurement is consistent with the actual transmission working conditions. Due to strict measurement conditions, error...

Problems solved by technology

This traditional method is not only difficult to ensure the position accuracy of the end face of the tapered bearing and the end face of the housing, but also does not simulate the actual working conditions of the transmission, which will cause the measurement conditions to be inconsistent with the actual situation, and at the same time, it is very easy to produce human errors, resulting in measurement accuracy. Low, labor cost waste, low work efficiency
