[0016] This utility model includes a drum surge cleaning telescopic drum rotation positioning detection device, such as... Figure 1 As shown, a linear guide rail 8 is longitudinally mounted on the bracket 9. A fixing plate 7 is slidably mounted on the linear guide rail 8 via a slider 17. The outer side of the fixing plate 7 is connected to the connecting seat 6. The connecting seat 6 is connected to the fixing frame 5. One end of the fixing pin 2 is fixedly mounted on the fixing frame 5. A fixing block 3 is rotatably mounted on the fixing pin 2. The probe rod 1 is longitudinally mounted on the fixing block 3. The sensing arm 13 is transversely mounted on the fixing block 3. The probe rod 1 and the sensing arm 13 are in a vertical structure. Tension spring fixing rods 4 are respectively mounted on the fixing frame 5 and the sensing arm 13. Both ends of the tension spring 12 are respectively fixed on the tension spring fixing rods 4. A connecting block 10 is mounted on one side of the fixing plate 7. The cylinder 11 is connected to the connecting block 10. A switch frame 14 is provided to match the position of the sensing arm 13. A proximity switch 15 is provided on the switch frame 14.

[0017] like Figure 2 and Figure 3 As shown, the bracket 9 and cylinder 11 of the telescopic rotation positioning detection device I are fixed to the housing of the surge cleaning device. The probe 1 rotates under the drive of the drum lever 20, causing the sensing arm 13 to rotate until the proximity switch 15 issues a command. The probe device returns to its original position via the tension spring 12, and the cylinder 11 drives the probe device to reciprocate up and down. A rotation positioning pin 17 corresponding to the engine cylinder bore is installed on the housing of the cleaning device for positioning.

[0018] The engine block enters horizontally into the rotary drum of the surge cleaning station, and the cleaning process requirements are as follows:

[0019] Rotate the cylinder block 90 degrees counterclockwise (turn to the position of pin 17) → clean the main oil passage with high-pressure insertion pipe → clean the continuous rotary surge.

[0020] The work process is as follows:

[0021] like Figure 4-6 As shown, the original position of the telescopic rotation detection device is: the cylinder drives the probe rod to insert downwards, waiting.

[0022] Action loop:

[0023] →The workpiece is in place at the surge cleaning station and the door is closed. The rotary drum 8 drives the workpiece (cylinder 19) to rotate counterclockwise.→

[0024] →The lever 20 on the drum wheel contacts the probe 1, driving the probe 1 to rotate, which in turn drives the sensing arm 13 to rotate.→

[0025] →The sensing arm 13 rotates to the proximity switch 15, sending a return-to-position signal→

[0026] →Drum 18 drives the reducer to stop and brake, then rotates to position pin 17 for positioning→

[0027] → Cylinder 11 actuates, causing probe 1 to retract →

[0028] →The sensing arm 13 rotates back to its original position under the action of the tension spring 12 →The probe is fully retracted, achieving rotational avoidance →

[0029] →The cylinder block oil passage cleaning device is activated; oil passage cleaning complete.→

[0030] →Remove the pin from the drum wheel latching device→

[0031] → Drum 8 continues to rotate, driving the workpiece to perform continuous rotating surge cleaning. After cleaning, the door is opened and the workpiece is sent out. → Cylinder 11 is activated, driving probe 1 to descend, waiting for the next work cycle.
