Description

Technical Field

[0002] As a core component of modern mechanical equipment, bearings directly affect the operational accuracy and service life of such equipment.1 In the field of industrial robots, the precision requirements for robotic arm bearings are particularly stringent; deviations in outer diameter dimensions can lead to problems such as inaccurate positioning and increased vibration of the robotic arm.6 Currently, bearing outer diameter inspection mainly faces the following technical challenges: Traditional inspection methods often involve manual measurement using vernier calipers or micrometers. Operators must measure the outer diameter of each bearing at different locations and manually record the data. This method is not only time-consuming and labor-intensive, but also prone to measurement errors due to visual fatigue. Especially for bearings produced in batches, manual inspection has become a bottleneck to production efficiency. Furthermore, most inspection devices are designed only for bearings of specific specifications. When the product model changes, the fixtures need to be replaced or the mechanism adjusted, affecting production efficiency. Summary of the Invention

The bearing 11 is placed on the placement rods 5. A rotating motor 12 is mounted on the bottom of the device body 1 via a motor bracket. The output shaft of the rotating motor 12 passes through the device body 1 and is mounted on the rotating disk 3. A device housing 7 is mounted on the top of the device body 1. A fixed top block 9 is mounted on the device housing 7. A transmission cavity 13 is opened on the device housing 7. A screw 15 is rotatably mounted in the transmission cavity 13.

[0021] Specifically, in this embodiment, each of the multiple placement rods 5 is equipped with an upwardly extending stop 6 at its end, which can prevent the bearing 11 from slipping off the placement rod 5 during the testing process.

[0022] Specifically, in this embodiment, the stop block 6 is made of rubber and is detachably connected to the placement rod 5 by bolts, allowing for quick disassembly and replacement of the stop block 6, which facilitates subsequent maintenance.

[0023] Specifically, in this embodiment, the fixing top block 9 is fixed to the device housing 7 by bolts, which enables the quick replacement of the fixing top block 9 and ensures the service life of the device.
