It has the advantages of high detection efficiency, high precision, light weight, simple and convenient operation, automatic data conversion, safety and environmental protection, etc.

Description

technical field [0001] The invention relates to a magnetic semicircle circumference measuring instrument for a bearing bush. Background technique [0002] Bearing semi-circle circumference detection is the key precision measurement of the bearing, which directly affects the accuracy level, price and technical performance requirements of the product. At present, the testing instruments for the semi-circle circumference of the bearing bush mainly include: torque wrench, dial gauge plus semi-circle tire tool, cylinder hydraulic semi-circle circumference tester. Torque wrench and dial indicator plus half-circle mold have very low detection efficiency and large measurement error due to different torque accuracy and individual measurement problems; the cylinder hydraulic semi-circle circumference detector is large in size and unstable in hydraulic pressure , but also to check the different pressure values ​​frequently, the measurement accuracy error is large, cumbersome, the meas...

Problems solved by technology

Torque wrench and dial indicator plus half-circle mold have very low detection efficiency and large measurement error due to different torque accuracy and individual measurement problems; the cylinder hydraulic semi-circle circumference detector is large in size and unstable in hydraulic pressure , but also to check the different pressure values ​​frequently, the measurement accuracy error is large, cumbersome, the measurement data must read the dial gauge, must be used by professionals, the utilization efficiency is low, and the data measured by the weather environment and temperature changes change Larger, this size is related to the interference fit between the bearing bush and the seat hole, the compression deformation and the assembly accuracy of the clearance fit of the journal, which directly affects the service life
