Description

Technical Field

[0001] The present invention relates to the field of eddy current testing equipment, and more specifically, to a synchronous pulley eddy current testing machine. Background Art

[0002] Synchronous belt drive consists of a closed annular belt with equally spaced teeth on its inner peripheral surface and corresponding belt pulleys. During operation, the belt teeth mesh with the pulley grooves to transmit motion and power, which is a meshing drive. Therefore, it has the characteristics of gear drive, chain drive, and flat belt drive, and is widely used in fields such as automobiles, textiles, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial machinery, stage lighting, communication food machinery, medical machinery, steel machinery, petrochemical industry, instrumentation, and various precision machine tools. Before leaving the factory, synchronous pulleys usually need to be subjected to eddy current testing on their upper end faces, lower end faces, inner peripheral faces, and outer peripheral faces to determine whether there are crack defects. During the testing process, the entire outer peripheral face of the synchronous pulley is usually regarded as a circumferential face for testing. The existing testing methods usually use manual hand-held eddy current detectors for testing, and there are also some automated testing equipment. However, a manipulator is provided beside each station for this type of equipment. After the testing at the previous station is completed, it is picked up and placed at the next station by the manipulator before the testing at the next station can be carried out. This results in a downtime waiting time between stations, and this type of equipment cannot achieve rapid clamping and holding of synchronous pulleys, and the testing efficiency is not high.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Invention

The horizontal panel 7 is arranged between the feeding conveyor line 2 and the qualified product discharging conveyor line 3. On one side of the horizontal panel 7 on the frame 1, an outer peripheral surface eddy current detection component 9, an inner peripheral surface eddy current detection component 10, an upper end surface eddy current detection component 22, a flipping component 11 for flipping the lower end surface of the product upward, and a lower end surface eddy current detection component 12 are sequentially arranged in the direction from the feeding conveyor line 2 towards the qualified product discharging conveyor line 3. Below the middle of the outer peripheral surface eddy current detection component 9, the inner peripheral surface eddy current detection component 10, and the upper end surface eddy current detection component 22 on the frame 1 and below the lower end surface eddy current detection component 12, a rotating table 18 is respectively arranged. A three-jaw chuck 19 is arranged on the rotating table 18.
