Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing clearance sorting measurement, in particular to a comprehensive bearing clearance sorting measurement method. BACKGROUND

[0002] The first generation of automobile hub ball bearing has the advantages of low production cost, simple structure, and bearing combined load of radial and axial load.

[0003] The assembly process of the first generation of hub bearing is: inner and outer ring cleaning → axial clearance selection and sleeve assembly → grease injection → sealing ring assembly → torque detection. The axial clearance selection is mainly selected by X195A shaft instrument by manual selection. In the selection process, the operation skill of the staff is required to be high, the selection efficiency is low, and the repeatability of X195A measurement is poor. The measurement gestures and actions of each person are different, and the detected axial clearance value has certain difference.

[0004] Therefore, it is very necessary to study a comprehensive bearing measurement and sorting method to solve the instability of manual measurement and the low selection efficiency.

[0005] The manual selection of axial clearance is to randomly select the inner and outer ring sleeve by the fixed steel ball gauge value, measure the axial clearance value of the bearing by X195A, calculate and test, and then select different steel ball gauge values to meet the axial clearance requirement.

[0006] The conventional axial clearance detection method is to detect by X195A. The principle of X195A shaft instrument is to fix the bearing outer ring 7, and the upper end of the bearing inner ring 2 is provided with an upper load 2Q and the lower end is provided with a lower load Q. First, the upper load switch 10 is loosened, the upper load 2Q is applied to the upper end of the bearing inner ring 2, and the value in the indicating table 8 is read as C1. Then, the upper load switch 10 is loosened, the lower load Q is applied to the lower end of the bearing inner ring 2, and the value in the indicating table 8 is read as C2. The maximum axial clearance C1-C2 of the inner ring inside the bearing under the load Q is called the axial clearance. (as shown in the attached Figure 8 )

[0007] 1. The X195A shaft instrument is used to detect the axial clearance. Since the upper load switch 10 is loosened, the staff's gestures, weight and speed have a certain impact on the loading of the upper end of the inner ring, so that the manual detection of the axial clearance has instability;

[0008] 2. When reading the axial clearance value, the staff needs to calculate C1-C2 by mental arithmetic. When selecting the clearance in batches, the staff is easy to make data reading or calculation errors due to fatigue;

[0009] 3. Many factors affect bearing clearance. The groove diameter, groove position, curvature, and groove parallelism difference of the inner and outer rings of the bearing directly affect the bearing clearance. In particular, the groove parallelism difference is a problem. Because the inner ring is stationary during the clearance test by X195A, only the axial clearance at a certain point of the inner ring is measured, and the influence of groove parallelism difference on axial clearance is not taken into account. Summary of the Invention

Step six: after the record is completed, the maximum and minimum values are automatically removed by the computing device, then the average value is calculated, and then the corresponding material channel is entered according to the average interval value according to the system setting; The inner ring comprehensive measurement sorting method comprises: Step one: before starting the device, the surface of the device, the manipulator, the sorting module (9) and the inner ring (11) spare parts are inspected to check whether there is damage, after the inspection is completed, the device table and the place where work is needed are cleaned to prevent the device parts from being damaged during work, and after the completion, the next step operation is performed; Step two: start the device, and move the inner ring (11) to the lower side of the sorting module (9) by the manipulator; Step three: then, the inner ring (11) is pushed upward by the device driving ejector rod (22) with a force of 100N, so that the inner ring (11) channel is in contact with the steel ball (1202) and closely fitted during the upward movement of the inner ring (11), thereby facilitating the next step operation; Step four: then, the device driving ejector rod (22) is rotated to drive the inner ring (11) and the retainer assembly (12) to rotate together; Step five: finally, when the inner ring (11) and the retainer assembly (12) rotate together, the second position sensor (14) is arranged to randomly collect the interval value D02 of the inner ring (11) channel, the curvature and the steel ball contact point and the use surface, and record; Step six: after the record is completed, the maximum and minimum values are automatically removed by the computing device, then the average value is calculated, and then the corresponding material channel is entered according to the average interval value according to the system setting.
