Description

Technical Field

[0001] The utility model relates to the technical field of bearing detection equipment, in particular to an auxiliary tool for roundness detection of bearing parts. Background Art

[0002] A roundness tester is a precision instrument for measuring the out-of-roundness of rotating surfaces of parts. It is often used to detect the roundness of bearing parts and then select qualified bearing rings. The roundness of bearing parts is one of the important structural parameters of bearings. If the roundness of bearing parts does not meet the standards, it will directly affect the rotation accuracy, vibration and noise of the bearings. It will also affect the clearance, stiffness, friction torque of the bearings, and even the fatigue life and working reliability of the bearings. Therefore, the measurement and control of bearing parts are very important links, especially for high-tech bearings such as military, railway, precision, and automotive bearings. The measurement of roundness indicators is even more important.

[0003] At present, the roundness measurement of bearing parts is often carried out manually with the help of a roundness measuring instrument. The measuring instrument probe does not move the rotating workpiece for measurement. During measurement, the workpiece is placed manually and the concentricity of the workpiece and the instrument platform is adjusted manually. The "one piece, one adjustment" method is adopted, which has low measurement efficiency and long adjustment time. Utility Model Content

During actual testing, the standard part is first placed on the limit step set on the three-jaw clamp for limit fixation, and then the roundness tester probe is moved to contact the standard part, and the four adjustment rods of the roundness tester detection platform are adjusted to ensure that the detection auxiliary tool is concentric with the detection platform, and the roundness value of the instrument is calibrated, and then the locking disk is released, and the position of the three-jaw clamp is adjusted by the locking disk, and finally the workpiece to be measured is placed on the limit step of the three-jaw clamp and fixed, and the roundness tester probe is moved so that the probe contacts the workpiece to be measured for measurement, which can greatly reduce the adjustment time when measuring the workpiece and improve work efficiency.

[0007] Preferably, the surface of the three-jaw clamp chuck is provided with three limiting grooves distributed in a circular array with the center of the three-jaw clamp chuck as the center of the circle, and the bottom of the three-jaw clamp is correspondingly embedded and installed in the three limiting grooves to facilitate rapid and stable installation and docking between the three-jaw clamp chuck and the three-jaw clamp.
