[0020] A method for using the inner barrel lifting rib screw driving machine comprises the following steps:

[0021] Step 1: manually put the pre-assembled cylinder on the belt of the feeding conveyor, and the cylinder is transported to the top of the pre-positioning mechanism with the belt, and the blocking cylinder pushes the push plate to adjust the cylinder and continue to move forward, and the second sensor senses the existence of the cylinder;

[0022] Step 2: The lifting cylinder works to push the support plate upward, and the supporting plate moves upward with the support plate. At the same time, the fastening cylinder retracts, and the upper wedge moves outward under the thrust of the spring, and pushes the lower wedge downward. The two fastening blocks open as their respective upper wedges move outward, so that the supporting plate lifts the cylinder from the belt, and the fastening blocks fasten the cylinder from the bottom;

[0023] Step 3: The pre-rotation motor starts to work, driving the support plate and the cylinder to rotate until the sensor 3 detects the positioning hole on the side wall of the cylinder, and then stops rotating;

[0024] Step 4: Driven by the external manipulator, the transfer and reinforcement fixture moves to the top of the cylinder and moves downward. The embracing cylinders on the edge of the middle plate work at the same time. The embracing cylinders pull the embracing blocks to contract through the connecting blocks, so that the embracing blocks hold the cylinder from the outside. Driven by the external manipulator, the transfer and reinforcement fixture directly lifts the cylinder from the support plate, and transfers the cylinder to the outer arc block of the lifting plate.

[0025] Step 5: The rotating cylinder works, driving the small turntable to rotate. The small turntable pushes the inner arc block through the pull rod, so that the inner arc block moves outward along the clamping cylinder guide rail and opens, so that the inner arc block contacts and applies force outward to the bottom side of the cylinder, and the inner arc block and the outer arc block clamp the cylinder together;

[0026] Step 6: The rib-fixing motor works to drive the rotating block to rotate, and the rotating block pushes the rib-fixing block through the pull rod, so that the rib-fixing block and the slider move outward along the rib-fixing guide rail and open, so that the pressure block on the outer side of the rib-fixing block contacts and presses the lifting rib from the inside;

[0027] Step 7: At this time, a screw hole on the outer wall of the cylinder is facing the screwdriver bit, and the radial cylinder works to push the moving seat to move along the radial guide rail to approach the outer wall of the cylinder; the feed motor works to push the screwdriver bit through the support block to pass a screw in the joint forward; the feed motor and the small motor work at the same time to provide the screwdriver bit with feed force and rotation when locking the screw, thereby completing the locking of a screw;

[0028] Step 8: The feed motor works in the reverse direction, driving the screwdriver bit to retract through the support block; the tangential cylinder works, driving the slide plate to move along the tangential guide rail, and the moving seat and the screw locking assembly move accordingly; the lifting motor works, driving the screw rod to rotate through the belt transmission mechanism, so that the lifting plate matched with the screw rod spiral pair moves up, and the lifting plate moves up with the lifting plate; at the same time, the external manipulator works synchronously, driving the transfer and reinforcement fixture to move up, so that the cylinder moves up with the lifting plate and the transfer and reinforcement fixture, and the other screw hole on the outer wall of the cylinder faces the screwdriver bit;

[0029] Step 9: Repeat the screw tightening action in step 7 to complete the tightening of the second screw.

[0030] The beneficial effects of the present invention are as follows:

[0031] The invention has a compact and reasonable structure and is easy to operate. The pre-assembled cylinder is circumferentially positioned and aligned through a pre-positioning mechanism. An external manipulator drives a transfer and rib-fixing tooling to transfer the aligned cylinder from the pre-positioning mechanism to the lifting plate. The lifting upper piece clamping mechanism works to clamp the cylinder wall. The rib-fixing mechanism on the transfer and rib-fixing tooling applies a thrust to the lifting rib from the inside. The screw locking mechanism works to lock the screws from the outside of the cylinder to the inside, so that the lifting rib is fastened to the inner wall of the cylinder, thereby realizing automatic locking of the lifting rib in the inner cylinder, replacing manual work, greatly improving work efficiency, and ensuring the stability and reliability of screw locking, reducing or even avoiding the problem of missed locking.

[0032] The present invention also includes the following advantages:

[0033] The existence of the rib fixing mechanism enables the lifting rib to stably bear the force received when the screw is tightened, ensuring the smooth tightening of the screw;

[0034] The lifting mechanism and the external manipulator lift the cylinder synchronously. At the same time, the locking screw assembly moves along the tangential guide rail under the drive of the tangential cylinder, thereby adjusting the position of the locking screw on the cylinder, realizing the locking of screws at different heights and angles on the cylinder, which is highly practical.

[0069] like Fig.11 As shown, the structure of the pre-positioning mechanism 2 is as follows: it includes lifting cylinders 21 arranged relatively and fixedly mounted on a machine base 61, the output ends of the two lifting cylinders 21 are both upwardly facing and the ends are commonly mounted with a support plate 25, an inverted U-shaped motor base 23 is mounted on the support plate 25, a pre-rotation motor 22 is mounted at the bottom of the motor base 23, the output end of the pre-rotation motor 22 passes through the motor base 23 upward, a material tray 27 is mounted on the output end of the pre-rotation motor 22, and a fastening mechanism 26 is symmetrically mounted on the material tray 27;

[0077] Step 3: The pre-rotation motor 22 starts to work, driving the support plate 27 and the cylinder 20 to rotate until the sensor 14 detects the positioning hole 40 on the side wall of the cylinder 20, and then stops rotating;

[0078] Step 4: The transfer and reinforcement fixing tool 7 is driven by the external manipulator to move to the top of the cylinder 20 and move downward, and the embracing cylinder 74 on the edge of the middle plate 73 works at the same time, and the embracing cylinder 74 pulls the embracing block 76 to contract through the connecting block 75, so that the embracing block 76 holds the cylinder 20 from the outside; the transfer and reinforcement fixing tool 7 is driven by the external manipulator to directly lift the cylinder 20 from the supporting plate 27, and the transfer and reinforcement fixing tool 7 is driven by the external manipulator to transfer the cylinder 20 to the outer arc block 92 of the lifting plate 4;

[0079] Step 5: The rotating cylinder 91 works to drive the small turntable 93 to rotate. The small turntable 93 pushes the inner arc block 95 through the pull rod 94, so that the inner arc block 95 moves outward along the clamping cylinder guide rail 96 and opens, so that the inner arc block 95 contacts and applies force outward to the side of the bottom of the cylinder, and the inner arc block 95 and the outer arc block 92 clamp the cylinder 20 together;

[0080] Step 6: The rib fixing motor 773 works to drive the rotating block 774 to rotate, and the rotating block 774 pushes the rib fixing block 778 through the pull rod 776, so that the rib fixing block 778 and the slider 777 move outward along the rib fixing guide rail 775 and open, so that the pressure block on the outer side of the rib fixing block 778 contacts and presses the lifting rib 30 from the inside;

[0081] Step 7: At this time, a screw hole on the outer wall of the cylinder 20 is facing the screwdriver bit 584, and the radial cylinder 56 works to push the moving seat 57 to move along the radial guide rail 55 to approach the outer wall of the cylinder 20; the feed motor 581 works to push the screwdriver bit 584 through the support block 582 to pass a screw in the joint 586 forward; the feed motor 581 and the small motor 583 work at the same time to provide the screwdriver bit 584 with feed force and rotation when locking the screw, thereby completing the locking of a screw;

[0082] Step 8: The feed motor 581 works in the reverse direction, driving the screwdriver bit 584 to retract through the support block 582; the tangential cylinder 53 works, driving the slide plate 54 to move along the tangential guide rail 52, and the moving seat 57 and the locking screw assembly 58 move accordingly; the lifting motor 106 works, driving the screw rod 105 to rotate through the belt transmission mechanism 107, so that the lifting plate 104 matched with the screw pair of the screw rod 105 moves up, so that the lifting plate 4 moves up with the lifting plate 104; at the same time, the external manipulator works synchronously, driving the transfer and reinforcement fixture 7 to move up, so that the cylinder 20 moves up with the lifting plate 4 and the transfer and reinforcement fixture 7, and the other screw hole on the outer wall of the cylinder 20 faces the screwdriver bit 584;

[0083] Step 9: Repeat the screw tightening action in step 7 to complete the tightening of the second screw.

[0084] The invention is simple and convenient to operate, realizes the automatic locking of the screws of the lifting machine, replaces manual labor, greatly improves the production efficiency, ensures the reliability of the screw locking, and has strong practicality.
