[0058] How it works

[0059] Workpiece delivery: Place the workpiece 47 to be inspected on the outer diameter support block 7 and the outer diameter support block 13, press the start switch 46, the HLS6*40 SB double-rod platform cylinder 3 pushes out the TN10*40S double-rod cylinder 5 to push the workpiece 47 forward to make it enter the 10mm position (approximately) of the inclined block reference 19, the TN10*5S double-rod cylinder 12 pushes out and retracts, driving the axial displacement of the workpiece 47, so that the end face of the workpiece 47 fits 19 - the outer reference surface of the inclined block reference 19, the TN10*40S double-rod cylinder 5 pushes out, pushing the outer diameter & outer diameter radial of the workpiece 47 to fit against the vertical block reference 20 and keep it motionless.

[0060] Workpiece rotation: When the outer diameter is radially against the block reference 20, the MAL75 single-tube cylinder 31 is instructed to push out, so that the 580*3*1 rubber flat belt 42 is pressed against the workpiece 47, triggering the TN10*40S double-rod cylinder 5 to retreat, and at the same time the low-speed motor 25 is started and drives the workpiece 47 to rotate radially clockwise at a uniform speed of 10 rpm.

[0061] Data collection: When the outer diameter & outer diameter of the workpiece 47 are radially against the block reference 20, the two sets of 12MM micrometers 23 have touched the outer diameter & outer diameter of the workpiece 47 respectively. When the workpiece 47 rotates radially clockwise, the data collection box 44 completes the outer diameter runout data collection through the 12MM micrometer 23, and retains it for later data extraction and analysis. During the collection period, if the detection value exceeds the preset value, the product status alarm light 45 flashes red. When the workpiece 47 is returned, the operator marks, isolates, and scraps the corresponding workpiece 47. The synchronous data collection box 44 completes the outer diameter runout data collection through the 12MM micrometer 23, and retains it for later data extraction and analysis. During the collection period, if the detection value exceeds the preset value, the product status alarm light 45 flashes red. When the workpiece 47 is returned, the operator marks, isolates, and scraps the corresponding workpiece 47.

[0062] Workpiece retraction: When the low-speed motor 25 rotates 3 circles, it stops rotating, the TN10*40S double-rod cylinder 5 is pushed out, and the MAL75 single-tube cylinder 31 drives the 580*3*1 rubber flat belt 42 to retract, so that the workpiece 47 is freed from the rubber flat belt 42, and falls onto the outer diameter support block 7 and the outer diameter support block 13 by its own gravity with the help of the angle of the 19-bevel block reference 19, and triggers the TN10*40S double-rod cylinder 5 to retract, and the HLS 6*40 SB double-rod platform cylinder 3 to retract. The operator takes the workpiece 47 to complete the inspection.

[0063] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also includes other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
