[0001] The invention belongs to the technical field of detection equipment, and in particular relates to a defect detection method for a bearing ring of a motor. Background Art

[0002] Bearings are core parts in industrial automation equipment. If the outer ring surface is defective or worn, it will cause instability in the equipment operation process. Accumulated errors are more likely to cause equipment vibration, which will reduce the work quality. Therefore, the detection of bearings has become a very important task in the industry and is of great significance. This requires the use of bearing surface defect detection devices.

[0003] In the prior art, manual inspection methods are generally used to detect defects such as bumps, fractures, and black skin on the surface of bearing rings. This inspection method has poor accuracy, low efficiency, and is prone to missed detections. In addition, the inspection accuracy is easily affected by the level of proficiency, making it difficult to ensure the reliability and stability of the inspection quality. Summary of the invention

When the fixed seat at the top is lifted to the top of the temporary storage rack, the push cylinder operates to push the top fixed seat onto the second conveyor rack, and the second conveyor rack conveys the fixed seat to the limit position for detection, and the temporary storage rack The setting slows down the conveying time of the fixed seat, thereby reserving sufficient time for the inspection of the bearing rings, thereby ensuring the orderly and batch inspection of the bearing rings, and then the bearing rings at the top are pushed out to the second conveyor rack by the push cylinder, and then transported to the inspection point for inspection by the second conveyor rack, realizing the full automation of the bearing ring inspection, thereby greatly improving the efficiency of the bearing ring inspection; after the fixed seat is transported to the inspection point, the swing component controls the cleaning nozzle to rotate, so that the cleaning nozzle turns to the bearing ring, and at the same time the fixed seat controls the bearing ring to rotate, thereby realizing the cleaning of the outer surface of the bearing ring by the cleaning nozzle. After the cleaning is completed The swing assembly controls the detection part to rotate toward one side of the bearing ring, and the cleaning nozzle is reset at the same time. The fixed seat controls the bearing ring to rotate again, and the detection part detects the outer surface of the bearing ring. First, the outer surface of the bearing ring is cleaned by the cleaning nozzle to remove impurities and oil on the outer surface of the bearing ring. At the same time, the rotation of the bearing ring ensures that the outer surface of the bearing ring is cleaned, and the cleaning liquid on the outer surface of the bearing ring is dried, thereby improving the detection accuracy of the bearing ring; the bearing ring is flipped and clamped and then tested again to ensure that the outer surface of the bearing ring is tested.

DETAILED DESCRIPTION

[0051] like Figures 1 to 12 As shown, a defect detection method for a bearing ring of a motor according to the present invention comprises the following steps:

[0052] a. Preparation before testing

[0053] First, the test bench 1 is preliminarily cleaned and each component is reset, and the test bench 1 is tested to check whether the test bench 1 operates normally. Then, according to the size of the bearing ring 2 to be tested, a corresponding fixing seat 3 is prepared.

[0054] b. Fixing of bearing ring 2

[0055] 1) Conveying of fixed seat 3

[0056] First, the fixing seat 3 is placed on the first conveying frame 4 . When the first conveying frame 4 conveys the fixing seat 3 to the bottom of the blanking assembly 5 , the limiting assembly 6 extends out and abuts against the front side of the fixing seat 3 .

[0057] 2) Assembly of bearing ring 2

[0058] The bearing ring 2 automatically falls from the top of the blanking assembly 5 onto the fixing seat 3, so that the fixing seat 3 is automatically clamped on the bottom of the bearing ring 2, thereby completing the assembly of the bearing ring 2.

[0059] c. Conveying of bearing ring 2

[0060] 1) Temporary storage of fixed seat 3

[0061] After the bearing ring 2 is assembled, the first conveyor frame 4 conveys the fixed seat 3 assembled with the bearing ring 2 to the temporary storage component 7. The fixed seat 3 is located on the lifting member 8 at the bottom of the temporary storage component 7. The lifting member 8 lifts the fixed seat 3 upward so that the fixed seat 3 is mounted on the temporary storage frame 9. After repeating step b, the next fixed seat 3 assembled with the bearing ring 2 is lifted upward again, so that the next fixed seat 3 is against the previous fixed seat 3 and then continues to be lifted upward, thereby controlling the previous fixed seat 3 to rise. At the same time, the next fixed seat 3 is mounted on the position of the previous fixed seat 3, so that the fixed seats 3 are stacked one by one from bottom to top in the temporary storage frame 9.

[0062] 2) Removal of the fixing seat 3

[0063] After the uppermost fixed seat 3 is lifted to the top of the temporary storage rack 9 , the push cylinder 10 operates to push the upper fixed seat 3 to the second conveying rack 11 , and the second conveying rack 11 controls the fixed seat 3 to move to the limit block 12 .

[0064] d. Defect detection

[0065] 1) Cleaning

[0066] After the front side of the fixed seat 3 abuts against the limit block 12, the swing assembly 13 controls the cleaning nozzle 14 to turn to the side of the fixed seat 3, so that the cleaning nozzle 14 is aimed at the bearing ring 2 located on the fixed seat 3, and the fixed seat 3 controls the bearing ring 2 to rotate, and the cleaning nozzle 14 flushes the outside of the bearing ring.

[0067] 2) Detection

[0068] After the bearing ring 2 is cleaned, the swing assembly 13 rotates again, thereby controlling the detection member 15 to rotate toward one side of the bearing ring 2, and at the same time the cleaning nozzle 14 is reset, and then the fixed seat 3 drives the bearing ring 2 to rotate again, thereby completing the detection of the outer wall of the bearing ring 2.

The setting of the torsion spring makes a certain angle between the rotating seat 19 and the turntable 17. When the fixed seat 3 is not in use, the torsion spring controls the clamping seat 18 to rotate upward by a certain angle. When the blanking assembly 5 controls the bearing ring 2 to be lowered onto the fixed seat 3, the bottom of the bearing ring 2 abuts on the clamping seat 18. Under the influence of gravity, the clamping seat 18 rotates downward, so that the bottom of the clamping seat 18 abuts on the turntable 17. At the same time, the clamping sleeve 20 is clamped on the outer surface of the bearing ring 2, so that the bearing ring 2 is assembled to the fixed seat 3. When the bearing ring 2 needs to be removed, it only needs to be taken out axially, thereby realizing convenient disassembly and assembly between the bearing ring 2 and the fixed seat 3. The setting of the turntable 17 realizes that the fixed seat 3 can control the bearing ring 2 to rotate.

When the lifting member 8 lifts the fixed seat 3 upward, the two sides of the fixed seat 3 abut against the bottom of the bracket 31, and the fixed seat 3 continues to rise, so that the bracket 31 rotates upward, and then the fixed seat 3 rises to the top of the bracket 31, and then the lifting member 8 descends and resets, so that the two sides of the fixed seat 3 are mounted on the front side of the top surface of the bracket 31, and the setting of the limiting shaft 34 plays a limiting role on the rear side of the top surface of the bracket 31, so that the bracket 31 is supported on the bottom of the fixed seat 3, and when the next fixed seat 3 is lifted by the lifting member 8, the next fixed seat 3 abuts against the bottom of the previous fixed seat 3, and the two fixed seats 3 rise synchronously, so that the previous fixed seat 3 is mounted on the upper bracket 31, and the next fixed seat 3 is mounted on the lower bracket 31, thereby realizing the stacking of the fixed seat 3 and slowing down the conveying speed of the fixed seat 3, reserving enough time for the detection of the bearing ring 2, thereby realizing orderly and batch detection of the bearing ring 2.
