Description

Technical Field

[0001] The utility model belongs to the technical field of steel ball detection, and more specifically, particularly relates to a bearing steel ball size detection device. Background Art

[0002] When assembling steel balls and bearings, in order to ensure the running stability of the bearings, it is often necessary to test the size of the steel balls. There will be a range of values ​​when testing the size of the steel balls. As long as the size of the steel balls is within the range, it can meet the use requirements of the bearings.

[0003] For example, the existing application number CN202223011914.7 relates to a bearing steel ball detection tooling, which avoids the steel balls from being blocked at the detection holes, and avoids the small-diameter detection holes from being blocked, causing subsequent small-diameter steel balls to leak through the larger-diameter detection ports, thereby ensuring the effectiveness of the device in detecting and screening bearing steel balls; it includes a base, two groups of connecting plates and a sieve plate, the two groups of connecting plates are located on the left and right sides above the base, the sieve plate is tilted and fixed between the two groups of connecting plates, and the sieve plate is provided with detection holes with gradually increasing apertures from left to right in sequence, characterized in that it also includes two groups of fixed plates, a power mechanism, two groups of first rotating shafts and a vibration mechanism, the two groups of fixed plates are symmetrically fixed on the left and right sides of the top of the base, the first rotating shaft is rotatably connected to the fixed plate through the power mechanism, and the first rotating shaft is connected to the connecting plate through the vibration mechanism, and the vibration mechanism can drive the connecting plate and the sieve plate to vibrate.

[0004] Based on the above, the existing steel ball size detection devices mostly realize the detection and collection process of steel balls of different sizes by vibrating the sieve plate. However, in the process of detecting the steel balls, if the steel ball size is smaller than the minimum tolerance range value, the steel ball can still fall through the sieve plate into the corresponding collection box, thus affecting the detection effect when detecting the steel ball size, and the detection accuracy of the detection device when detecting the steel ball, and also affecting the use effect and operation stability of the bearing after the steel ball and the bearing are assembled.
