Device and method for measuring assembly height of flanged tapered roller bearing

The invention discloses an assembly height measuring device and method for a flanged tapered roller bearing, and aims to solve the problems of large measurement error and low measurement efficiency caused by a large amount of measurement data in an existing measurement mode. The measuring device comprises a measuring table, guide rails, a first dial gauge stand, a second dial gauge stand, a first dial gauge and a second dial gauge, the first dial gauge stand and the second dial gauge stand are located on the top of the measuring table and arranged left and right, the first dial gauge is arranged on the first dial gauge stand, the second dial gauge is arranged on the second dial gauge stand, and the guide rails are fixed to the top of the measuring table and arranged left and right. The two guide rails are located between the first gauge stand and the second gauge stand. When in use, a bearing to be measured is placed between the two guide rails, and the lengthened probes of the first dial indicator and the se
