The beneficial effect who so sets up is: the bearing inner ring is fixedly connected with the air spindle through the first tool, a proper mass block is selected to provide rated load, and axial load is applied to the bearing outer ring through the force guide rod and the second tool, so that the bearing parts are ensured to be in ideal contact positions. And starting the driving motor and adjusting the rotating speed to the target rotating speed, so that the outer ring of the bearing is in a stable rotating state, and the inner ring does not rotate. When the bearing is installed in a thousandth mode, the bearing can be in contact with the inner diameter surface and the end face of the inner ring of the bearing to be tested, the dial indicator value is recorded, the recorded indicator value changes to be the radial and axial runout indicator value of the inner ring of the bearing, and the outer ring runout value of the bearing can be detected in the same way. The structure is simple, the test is convenient and fast, the detection efficiency is effectively improved, and the detection accuracy is better.
According to the further arrangement of the invention, a positioning through groove for installing the dial indicator is arranged on the first tool and/or the second tool.
The beneficial effect who so sets up is: the dial indicator is convenient to install, the dial indicator is installed in place, the using effect of the overall structure is improved, and meanwhile, the dial indicator is simple in structure and beneficial to implementation.
According to the further arrangement of the invention, a first mounting hole is formed in the air main shaft, a second mounting hole is formed in the force guide rod, a first connecting column is arranged on the first tool, a second connecting column is arranged on the second tool, the first connecting column, the first mounting hole and the second mounting hole can be clamped, and the second connecting column, the first mounting hole and the second mounting hole can be clamped.
The beneficial effect who so sets up is: set up like this for first frock and second frock can exchange the position, satisfy the detection to bearing inner race or outer lane are beated, this kind of simple structure simultaneously, and the production and processing of being convenient for has good result of use.
As a further arrangement of the invention, a shaft sleeve is arranged between the force guide rod and the support frame.
The beneficial effect who so sets up is: set up like this for the use of guide force pole is more smooth and easy, and difficult card pause that appears improves overall structure's result of use.
