[0019] Example 3, as Figure 1-5As shown in the figure, the present invention provides a technical solution: a device for cleaning the flash on the inner cavity of an automotive aluminum alloy engine cylinder block, including a cylinder block 21 disposed at the top of a stamping press 1, and a positioning hole 23 is opened at the bottom end of the cylinder block 21. A plurality of stamping holes 22 are opened on the inner wall of the cylinder block 21. A T-shaped positioning block 13 is disposed inside the support frame 5 through a through hole at a position inserted into the stamping hole 22, and a roller 14 is installed at the bottom end of the T-shaped positioning block 13. A spring 15 that contacts the top end of the inner wall of the support frame 5 is sleeved on the outer wall of the T-shaped positioning block 13. A pushing connection mechanism is disposed inside the support frame 5. The pushing connection mechanism includes a fixed frame 8 and a second cylinder 9. A fixed frame 8 is installed on one side of the stamping press 1, and a second cylinder 9 is disposed inside the fixed frame 8. A pushing frame 10 for pushing the cylinder block 21 to unload is installed at the output end of the second cylinder 9. A chute 11 is opened at the middle position of the bottom end inside the support frame 5, and an inclined slider 12 is disposed inside the chute 11. The outer wall of the inclined slider 12 contacts the bottom end of the roller 14. An L-shaped frame 16 that penetrates the stamping press 1 and is connected to the pushing frame 10 is installed on one side of the inclined slider 12. By starting the second cylinder 9 to push the pushing frame 10 to move towards the cylinder block 21, and at the same time the pushing frame 10 is connected to the L-shaped frame 16, the L-shaped frame 16 is used to push the inclined slider 12 to move to the left inside the chute 11. At this time, the inclined slider 12 is at the contact surface position of the roller 14 to the lowest point inside the inclined slider 12. Under the action of the self-elastic force of the spring 15, the T-shaped positioning block 13 is driven to move downward until it does not contact the cylinder block 21. At this time, the pushing frame 10 pushes the cylinder block 21 to move to the contact position above the driving roller 3. At this time, start the first motor 4 to drive the sprocket and chain structure to drive a plurality of driving rollers 3 to rotate synchronously, and then drive the cylinder block 21 to fall to the position above the driving roller 3, and the automatic unloading can be completed. The automatic unloading can be completed, saving labor and improving the efficiency of cleaning the flash.

[0020] Working principle: First, connect the external power supply. The operator can place the cylinder block 21 above the driving roller 3. At this time, start the first motor 4 to drive the transmission shaft 2 to rotate. Thus, the transmission shaft 2 drives the driving roller 3 to convey the cylinder block 21 for loading and unloading up and down to the position below the stamping frame 7. Start the second cylinder 9 to push the pushing frame 10 to move towards the cylinder block 21. At the same time, the pushing frame 10 is connected to the L-shaped frame 16. Through the L-shaped frame 16, the inclined slider 12 is pushed to move to the right in the chute 11. At this time, the contact surface of the inclined slider 12 at the position of the roller 14 reaches the highest point inside the inclined slider 12, and the spring 15 is tightened. And the T-shaped positioning block 13 is inserted above the positioning hole 23. At this time, start the first cylinder 6 to push the stamping frame 7 into the cylinder block 21 to facilitate stamping the dead corners inside the cylinder block 21. The debris can fall through the falling groove above the stamping bed 1 into the inside of the support frame 5. The operator can start the second motor 20 to drive the forward and reverse screw rod 18 to rotate. Thus, the forward and reverse screw rod 18 drives the moving block 19 to move back and forth in the slide rail 17. Furthermore, the moving block 19 clears the debris falling from the stamping until it penetrates the support frame 5 and is discharged outside the stamping bed 1. When the cleaning is completed, start the second cylinder 9 to push the pushing frame 10 to move towards the cylinder block 21. At the same time, the pushing frame 10 is connected to the L-shaped frame 16. Through the L-shaped frame 16, the inclined slider 12 is pushed to move to the left in the chute 11. At this time, the contact surface of the inclined slider 12 at the position of the roller 14 reaches the lowest point inside the inclined slider 12. Under the action of the self-elastic force of the spring 15, the T-shaped positioning block 13 is driven to move downward until it does not contact the cylinder block 21. At this time, the pushing frame 10 pushes the cylinder block 21 to move to the contact position above the driving roller 3. At this time, start the first motor 4 to drive the sprocket and chain structure to drive multiple groups of driving rollers 3 to rotate synchronously, and then drive the cylinder block 21 to fall to the position above the driving roller 3, and the automatic unloading can be completed. The automatic unloading can be completed, saving labor and improving the efficiency of cleaning burrs.
