[0058] Working principle

[0059] Workpiece feeding: put the workpiece 47 to be detected on the first outer diameter supporting block 7 and the second outer diameter supporting block 13, press the start switch 46, the HLS 6*40 S B double-rod platform cylinder 3 pushes out to push the TN10*40 S first double-rod cylinder 5 forward, so that the workpiece 47 enters the 10mm position (about) of the inclined block reference 19, the TN10*5 S second double-rod cylinder 12 pushes out and retreats, driving the workpiece 47 to axially displace, so that the end face of the workpiece 47 abuts against the outer reference surface of the inclined block reference 19, the TN10*40 S first double-rod cylinder 5 pushes out to push the workpiece 47 to radially abut against the vertical block reference 20 and keep still.

[0060] Workpiece rotation: when the workpiece 47 radially abuts against the vertical block reference 20, the MAL75 single cylinder cylinder 31 is pushed out to make the 580*3*1 rubber flat belt 42 press against the workpiece 47, triggering the TN10*40 S first double-rod cylinder 5 to retreat, while the low-speed motor 25 starts and drives the workpiece 47 to rotate at a speed of 10 revolutions per minute in a clockwise direction,

[0061] Data collection: when the outer diameter of the workpiece 47 is in contact with the reference 20, the two sets of 12mm micrometer 23 have respectively touched the outer diameter of the workpiece 47. When the workpiece 47 rotates clockwise, the data collection box 44 completes the outer diameter runout data collection through the 12mm micrometer 23, and stores it for later data analysis. If the detected value exceeds the preset value during the collection, the product status alarm light 45 flashes red. After the workpiece 47 is returned, the operator will identify, isolate and scrap the corresponding workpiece 47. The synchronous data collection box 44 completes the outer diameter runout data collection through the 12mm micrometer 23, and stores it for later data analysis. Similarly, if the detected value exceeds the preset value during the collection, the product status alarm light 45 flashes red. After the workpiece 47 is returned, the operator will identify, isolate and scrap the corresponding workpiece 47.

[0062] Workpiece return: when the low-speed motor 25 rotates 3 turns, it stops rotating, the TN10*40S first double-rod cylinder 5 pushes out, the MAL75 single-cylinder 31 drives the 580*3*1 rubber flat belt 42 to return, so that the workpiece 47 is separated from the rubber flat belt 42, and falls onto the first outer diameter block 7 and the second outer diameter block 13 by its own gravity and the angle of the 19-inclined block reference 19, and triggers the TN10*40S first double-rod cylinder 5 to return, and the HLS 6*40 S B double-rod platform cylinder 3 to return. The operator takes the workpiece 47 to complete the detection operation.

[0063] The above description is only the preferred embodiment of the present application and the explanation of the technical principle and scheme used. Meanwhile, the scope of the invention involved in the present application is not limited to the technical solution formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
