Description

Technical Field

[0001] The utility model belongs to the technical field of steel ball flaw detection equipment, and in particular relates to an automatic steel ball flaw detection line device. Background Art

[0002] Bearings are widely used shaft parts supporting transmission parts. They are key basic parts of mechanical products and play a vital role in the normal operation of mechanical equipment. With the continuous improvement of the precision requirements of mechanical products, the precision requirements of bearings are also increasing. Bearings are required to maintain rotation accuracy, stable dynamic performance and extend their service life for a long time under the specified angular velocity and load. This places strict requirements on the surface and internal defect standards of bearing internal parts. Steel balls are key parts of rolling elements in bearings. They can withstand loads and are directly related to the dynamic performance of bearings. Their surface and internal quality directly affect the performance and service life of bearings. If the quality of steel balls is unqualified, it may cause bearing failure and even cause serious consequences.

[0003] The indicators for evaluating the quality of steel balls mainly include dimensional accuracy, geometric accuracy, appearance quality, internal quality, etc., among which the appearance quality also includes the roughness of the steel ball surface, the degree of defects and the uniformity of hardness, etc. In the batch manufacturing process, steel balls will inevitably have common surface or internal defects such as spots, pitting, scratches, scratches, pits, cracks, etc. No matter what form of defects, they will easily grow and extend, affecting the service life and operating characteristics of the bearing, and even damaging the bearing and causing a major accident. Therefore, it is a very critical step and technology to perform non-destructive testing on the steel balls inside the bearing before using it.

[0004] At present, there are two main non-destructive flaw detection methods for steel balls: ultrasonic flaw detection and eddy current flaw detection. The flaw detection in the industry is mostly carried out by single machine operation, and the steel balls are transported to different workstations for ultrasonic flaw detection and eddy current flaw detection operations. The number of loading and unloading times is large, and the intermediate process requires manual transportation. The steel balls that have passed the two non-destructive flaw detection tests need to be manually re-rust-proofed and packed. The existing process flow of non-destructive flaw detection of steel balls is:

[0005] Steel ball cleaning → manual wiping → loading → ultrasonic flaw detection → unloading → transfer → manual wiping → loading → eddy current flaw detection → unloading → transfer → manual rust prevention → packaging.

[0006] The existing non-destructive testing process is long, inefficient, and labor-intensive. Repeated loading, unloading, and transportation can easily cause surface damage to the steel balls, affecting the quality of the steel balls. In order to achieve the "zero defect" goal of steel ball production and use, an efficient steel ball non-destructive testing automated line detection device is urgently needed. Summary of the invention

[0024] The automatic anti-rust device 9 comprises a storage box, the inner wall of which is provided with a flexible buffer pad, and the storage box is provided with an oil spraying pipeline and an atomizing nozzle to spray oil on the steel balls.

[0025] The truss grabbing device 10 includes a truss and a grabbing mechanism. The truss includes two symmetrically spaced cross rails 101. A plurality of columns 107 are fixedly arranged at the bottom of the cross rails 101. The columns 107 are fixedly installed on the ground. A longitudinal rail 102 is slidably installed between the two cross rails 101. The grabbing mechanism includes an electro-hydraulic push rod 103 slidably installed on the longitudinal rail 102. A pneumatic suction cup 106 is fixedly connected to the end of the piston rod of the electro-hydraulic push rod 103.

[0028] Cleaning → Manual wiping → Loading → Ultrasonic flaw detection → Eddy current flaw detection → Anti-rust packaging

[0029] The working process of the automatic steel ball flaw detection line device is as follows: the cleaning oil attached to the surface of the cleaned steel ball is manually wiped off, and the steel ball is placed in the automatic loading position 2 of the ultrasonic flaw detector 1.
