[0039] Furthermore, it also includes a grasping device (not shown) for realizing the position transfer of the piston cylinder between adjacent devices.

[0040] In this embodiment, the piston cylinders to be inspected are sent out one by one from the feeding device 100, and the piston cylinders are transferred to the inner diameter gauge inspection device 300 by the grasping device, and the inner hole is first cleaned by the cleaning mechanism 301 thereon, and then the inner hole is measured by the inner diameter measuring mechanism 302 thereon;

[0041] The inner hole cleaning operation is as follows: the piston cylinder is first pressed by the downward moving cleaning block 3014, and then the brush rod 3013 which rotates and moves upward at high speed at the same time extends into the cylinder to brush the inner hole wall to achieve the cleaning function.

[0042] The inner hole measurement operation is as follows: first, the piston cylinder body is pressed by the inner diameter measuring pressing block 3024 which moves downward, and then the inner diameter gauge 3023 which moves upward is extended into the cylinder body to compare and measure the inner hole of the cylinder body.

[0043] After completing the measurement of the inner diameter gauge detection device 300, the workpiece is transferred by the gripping device to the outer diameter and total height detection device 400, where the outer diameter is first measured by the outer diameter detection unit 403 and then the height is measured by the height detection unit 404.

[0044] Among them, the outer diameter measurement operation is as follows: by inserting the side of the workpiece into the outer diameter measurement positioning groove 4032, since the outer wall of the workpiece is close to the air outlet, the feedback air pressure of the detection air source is compared with the feedback air pressure of the standard part. When the error is within the set range, it is qualified; when the error is outside the set range, it is unqualified.

[0045] The height measurement operation is as follows: the height measuring rod 4043 is moved downward to touch the top of the inverted cylinder until the height measuring rod 4043 cannot move downward any more, and the position sensor 4044 detects the downward movement distance, thereby calculating the actual height of the cylinder.

[0046] After completing the measurement of the outer diameter and total height detection device 400, the workpiece is transferred by the gripping device to the depth detection device 500, where the laser rangefinder completes the hole depth measurement of the inverted cylinder body, and the first industrial camera is used to take a photo of the inner contour shape.

[0047] After completing the measurement of the depth detection device 500, the workpiece is transferred to the inner contour through gauge detection device 600 by the gripping device, and the inner contour through gauge 602 on the inner contour positioning seat 601 completes the detection of the inner contour processing accuracy, and the adaptability of the through gauge is used to determine whether the workpiece is processed properly.

[0048] After completing the measurement of the inner contour through gauge detection device 600, the workpiece is transferred by the gripping device to the inner hole ring groove detection device 700. The workpiece is placed horizontally on the first turning roller 702 and the second turning roller 703 and rotates with the rollers. The first detection arm 705 moves forward, carrying the second industrial camera 706 and the first electro-light source, and extends into the cylinder body. The second industrial camera 706 takes a photo of an annular groove inside the cylinder body and compares it with the standard photo to determine whether the annular groove is qualified.

[0049] After completing the measurement of the inner hole ring groove one detection device 700, the workpiece is transferred by the gripping device to the inner hole ring groove two detection device 800. The workpiece is placed horizontally on the third flip roller 802 and the fourth flip roller 803, and rotates with the rollers. The second detection arm 805 that moves forward carries the third industrial camera 806 and the second electric light source and extends into the cylinder body. The third industrial camera 806 takes a photo of another annular groove inside the cylinder body and compares it with the standard photo to determine whether the annular groove is qualified.

[0050] After completing the measurement of the inner hole ring groove second detection device 800, the workpiece is transferred to the appearance detection device 900 by the gripping device. The workpiece is placed horizontally on the fifth turning roller 902 and the sixth turning roller 903 and rotates with the rollers. The fourth industrial camera above takes a photo of the cylinder body surface and compares it with the standard photo to determine whether the cylinder body surface is qualified.

[0051] After the measurement of the appearance inspection device 900 is completed, the workpiece is transferred from the gripping device to the unloading device 200 , and unloading is performed by the unloading device 200 .

[0052] It should be emphasized that the workpieces transferred to the next measuring station by the gripping device are all good products, and defective products will be rejected after each measurement operation.

[0053] The first power assembly 704 , the second power assembly 804 , and the third power assembly 904 all include a gear pair and a motor.

[0054] The rotating mechanism may be a rotating cylinder or an existing mechanism that performs the same function.

[0055] The linear reciprocating motion mechanism may be a push rod cylinder, or an existing mechanism that performs the same function.
