[0026] 2. When the oil casing is transported, one of the conveying rollers is driven by the stepper motor to rotate along the conveying frame, so that one of the conveying rollers drives the pulley to rotate, and the friction transmission of the belt makes multiple pulleys rotate synchronously, so that multiple conveying rollers rotate synchronously, and the rotating conveying roller transports the oil casing.

After the oil casing 22 is conveyed to the right place, the oil casing 22 is fixed by two fixing components 5, and the inner wall of the arc-shaped clamping block 504 abuts against the outer peripheral wall of the oil casing 22, so as to achieve stable fixation of the oil casing 22 and prevent shaking or displacement during the punching process. Then, the gantry 7 and the moving block 8 are moved to the appropriate punching position and the drilling operation is performed through the drilling component 9;

[0062] When drilling, the piston rod of the second cylinder 903 pushes the L-shaped block 904 to slide along the bracket 902, so that the L-shaped block 904 pushes the semicircular block 905 to move to a suitable height for use, and the output shaft of the forward and reverse motor 912 drives the central axis of the gear 911 to rotate, so that the gear 911 is meshed and connected with the gear ring 910 on the semicircular block 905, and the adjustment block 907 is pushed to slide along the inner wall of the limit groove 906, and the adjustment block 907 is slid to a suitable position along the semicircular block 905, and the drill bit 909 is driven to rotate by the output shaft of the drilling motor 908 to perform a drilling operation on the outer surface of the oil casing 22, and the feed amount of the drill bit 909 is controlled and adjusted by the corresponding gantry 7 and the use of the second cylinder 903 in cooperation with the moving block 8;

[0063] During the drilling process, the gantry 7 and the movement of the moving block 8 are used to cooperate with the use of the drilling assembly 9, which facilitates the drilling of different positions of the oil casing 22, and realizes the rapid adjustment of the height and position of the drilling assembly 9. The oil casing 22 does not need to be rotated, which reduces the complexity of the operation, improves the adjustment flexibility of the drilling, and improves the accuracy and efficiency of the drilling, and adapts to the drilling processing requirements of oil casing 22 of different sizes, shapes and materials;

[0064] When the oil casing 22 is transported, one of the transport rollers 2 is driven by the stepper motor 4 to rotate along the transport frame 1, so that one of the transport rollers 2 drives the pulley 3 to rotate, and the friction transmission of the belt 6 causes multiple pulleys 3 to rotate synchronously, so that multiple transport rollers 2 rotate synchronously, and the rotating transport rollers 2 transport the oil casing 22;

[0065] After being transported to a suitable processing position, the stepper motor 4 stops rotating, and the piston rod of the first cylinder 503 pushes the push rod 501 to drive the multiple positioning blocks 502 to move to one side of the oil casing 22, so that the positioning blocks 502 slide along the conveying frame 1, and the inner wall of the arc-shaped block 504 abuts against the outer wall of the oil casing 22 to fix the oil casing 22, providing favorable conditions for the drilling assembly 9, facilitating the positioning and use of the oil casing 22, avoiding displacement during the drilling process, ensuring the accuracy and consistency of subsequent processing such as drilling, and conveniently adapting to the positioning requirements of oil casing 22 of different specifications.

[0066] After the oil casing 22 is fixed, the first screw 11 is driven to rotate along the first support block 12 by the output shaft of the first servo motor 13, and the gantry 7 and one of the drilling components 9 are pushed to move to a suitable drilling processing position, so that the gantry 7 slides along the first guide rail 10 and the top surface of the conveyor frame 1, and the slide 20 is driven to slide by the slide 19 of the rodless cylinder 18 installed on the gantry 7, so that the adjustment block 907 drives the drill bit 909 to move synchronously, and the drill bit 909 is radially adjusted along the sliding direction of the slide 20, and the synchronous movement of the second cylinder 903 is coordinated to facilitate the feeding of the drill bit 909 in different directions when drilling, and one of the drilling components 9 is adjusted to a suitable use position, and then the upper end and the outer surfaces on both sides of the oil casing 22 are drilled through the drilling component 9;

[0067] At the same time, the second screw 14 is driven by the output shaft of the second servo motor 16 to rotate along the second support block 15, pushing the moving block 8 to slide along the inner wall of the conveying frame 1 and the second guide rail 17, and the slide 19 of the rodless cylinder 18 installed on the moving block 8 drives the slider 20 to slide, so that the other drilling component 9 is moved to a suitable use position, and the drill bit 909 is pushed to move to a suitable height by the piston rod of the corresponding second cylinder 903, and the slide 19 on the rodless cylinder 18 slides, so as to facilitate the driving of the drill bit 909 to move horizontally and vertically, and at the same time drive the drill bit 909 to slide to different positions along the semicircular block 905, and perform drilling operations on the lower end and the outer surfaces on both sides of the oil casing 22, thereby improving the adaptability and processing efficiency of the equipment, ensuring the accuracy of the drilling operation, improving the processing accuracy of the oil casing 22, reducing the processing errors caused by equipment shaking or offset, and improving the processing quality.

[0068] When drilling, the dust suction pipe 2102 is sucked through the air inlet end of the dust suction fan 2103. At this time, the dust suction pipe 2102 generates negative pressure to suck the air inside the dust suction cover 2101 and transport it to the inside of the dust suction fan 2103, and suck the smoke and debris inside the dust suction cover 2101 caused by the drill bit 909 drilling. The dust suction fan 2103 sucks the smoke and debris and transports them to the dust collecting bag for collection, thereby reducing the impact of the debris on the oil casing 22, improving the cleanliness of the drilling surface, reducing the impact of the smoke and debris generated during the drilling process on the working environment and operators, and timely removing the smoke and debris near the drilling area, thereby improving the processing accuracy and product quality.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
