[0044] The PLC controller is electrically connected to the first motor 22 .

[0045] The clamping portion includes a fixed block 3, and two first placement grooves 31 are symmetrically opened on one side of the fixed block 3. A clamping plate 32 is arranged in each first placement groove 31. The clamping plate 32 is partially located on the outer side of the corresponding fixed block 3, and the clamping plate 32 is slidably connected to the corresponding first placement groove 31.

[0046] A moving assembly 4 is disposed on each fixed block 3 , and the moving assembly 4 changes the distance between the corresponding two clamping plates 32 .

[0050] The bottom plate 11 is provided with a lifting assembly 5. The lifting assembly 5 includes two telescopes 51, both of which are fixed on the top of the bottom plate 11, and a bearing plate 52 is fixed to the telescopic ends of the two telescopes 51, and the bearing plate 52 is located between the two clamping parts. The PLC controller is electrically connected to the two telescopes 51.

[0051] The implementation principle of the above embodiment is:

[0052] The operator first adjusts the distance between the two clamping plates 32 on each fixing block 3 according to the size of the cylinder head.

[0053] Before starting the machine, the carrying plate 52 is located between the two clamping plates 32 on the same fixed block 3, and the operator adjusts the height of the carrying plate 52 through the PLC controller.

[0054] When the cylinder head is placed on the carrying plate 52 , two ends of the cylinder head are respectively located between the corresponding two clamping plates 32 .

[0055] The operator connects the power supply. The PLC controller starts the two second motors 44, which drive the corresponding second screws 42 to rotate, and the second second motors 44 drive the corresponding second rotating rods 43 to rotate, and the second rotating rods 43 drive the corresponding first screws 41 to rotate. The first screws 41 and the second screws 42 have the same shape, but the thread directions are opposite.

[0056] As the first screw rod 41 and the second screw rod 42 rotate, the two clamping plates 32 start to move, and both clamping plates 32 contact the surface of the cylinder head and fix the position of the cylinder head. During the clamping process of the clamping plates 32, since the height of the bearing plate 52 is adjusted in advance, the cylinder head and the bearing plate 52 are not out of contact.

[0057] When the cylinder cover is fixed, the operator starts the third motor 72 through the PLC controller, and the third motor 72 drives the third screw rod 71 to rotate, and the rotation of the third screw rod 71 drives the sliding block 73 to move along the straight line direction of the guide rod 74 itself.

[0058] The movement of the sliding block 73 changes the position of the connecting portion 81 , and the connecting portion 81 drives the power cylinder 6 and the punch 61 to move.

[0059] After the position of the punch 61 is adjusted, the operator starts the power cylinder 6 and the punch 61 through the PLC controller, and the power cylinder 6 drives the punch 61 to move downward. After the punch 61 drills a hole on the cylinder cover, the power cylinder 6 drives the punch 61 back to the initial position.

[0060] When the operator needs to change the drilling position on the cylinder head, this position is not directly below the third screw rod 71 .

[0061] The operator starts the fourth motor 8 through the PLC controller according to the processing drawing. The fourth motor 8 drives the connecting part 81 to rotate, and the connecting part 81 drives the power cylinder 6 to move. After the power cylinder 6 moves to the appropriate position, the position of the sliding block 73 is adjusted by the third motor 72.

[0062] Finally, the punching machine 61 is driven by the power cylinder 6 to perform punching operation on the cylinder cover.

[0063] After drilling on one side of the cylinder head is completed, drilling operations need to be performed on the other sides of the cylinder head.

[0064] The operator first starts the two retractors 51 through the PLC controller, and the two retractors 51 drive the carrying plate 52 to move downward for a certain distance.

[0065] The operator then starts the first motor 22 through the PLC controller, and the first motor 22 slowly rotates to drive the first rotating rod 23 to rotate, the first rotating rod 23 drives the connected clamping part to rotate, the clamping part drives the cylinder cover to rotate, and the cylinder cover drives another clamping part to rotate.

[0066] When the surface of the cylinder head to be processed is located directly below the punching machine 61 , the first motor 22 stops rotating.

[0067] The operator then moves the carrying plate 52 to the initial position through the PLC controller.

[0068] The operator then performs the drilling operation in the above manner.

[0069] After the drilling operation is completed, the second motor 44 is started by the PLC controller, and the second motor 44 returns the two clamping plates 32 to the initial position, that is, the clamping plates 32 are out of contact with the cylinder head, and the operator takes out the cylinder head and places a new cylinder head of the same specification.

[0070] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
