Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, in particular to a multi-station drilling equipment for flange processing. Background Art

[0002] Flanges are parts that connect pipes to each other, used to connect pipe ends or two devices. Flanges have multiple bolt holes, so during flange manufacturing, bolt holes need to be drilled around their periphery. However, current flange drilling devices have the following main problems:

[0003] (1) Traditional flange drilling equipment is mostly single-station design, which requires frequent fixture replacement and parameter adjustment during processing. It requires a lot of manual intervention and cannot achieve simultaneous processing of multiple flanges, resulting in low efficiency. (2) Each time a hole is drilled, either only one flange can be drilled, but the drilling efficiency is low; or multiple flanges can be drilled at the same time, but the multiple flanges are overlapped, which will increase the overall thickness of the flange, increase the drilling pressure, and shorten the life of the drill rod. (3) Each time a hole is drilled, only holes can be drilled on the flange one by one, and it is impossible to drill multiple holes on the flange at the same time, resulting in low drilling efficiency. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

The multi-hole drilling mechanism is located on one side above the turntable, and the movement of the positioning mechanism is controlled by a linear displacement mechanism, so that the positioning mechanism can be aligned with the multi-hole drilling mechanism.

[0007] Preferably, the multi-hole drilling mechanism includes a lifting plate, which is connected to the lifting mechanism, and the center of the bottom surface of the lifting plate is fixedly connected to a polygonal block, and the periphery of the lifting plate is fixed with multiple connecting plates corresponding to the edges of the polygonal blocks, and the connecting plates and the corresponding edges are connected to a first guide rod, and the first guide rod is slidably connected to a first slide, and a drilling rig is installed on the bottom surface of the first slide, and a first cylinder is installed on the outer side of each connecting plate, and the telescopic end of the first cylinder passes through the connecting plate and is connected to the first slide.

[0008] In this technical solution, the lifting mechanism operates to lower the lifting plate, allowing the drill rod to contact the flange, thereby completing the drilling operation. The first cylinder, in turn, drives the first slide on the first guide rod to adjust the position of the drill rod, thereby adjusting the position of the drill rod according to the flange radius. During operation, the position of each drill rod is adjusted individually. After each adjustment, the distance between the drill rod and the center of the polygonal block is measured using a ruler until all drill rods are at equal distances from the center of the polygonal block, allowing for subsequent batch drilling.

[0009] Preferably, the first rotating mechanism includes a first motor installed in the base, a first transmission shaft connected to the first motor through a coupling, a first gear fixedly connected to the first transmission shaft, and a second gear fixedly connected to the rotating column, and the first gear is meshed with the second gear.

[0010] The above technical solution starts the first motor to drive the first transmission shaft to rotate, and through the cooperation of the first gear and the second gear, drives the rotating column to rotate, thereby driving the turntable to rotate, so that the positioning mechanism reaches the bottom of the multi-hole drilling mechanism one by one to achieve continuous drilling operations.

[0011] Preferably, the linear displacement mechanism includes two bearing seats fixed on the turntable and arranged along its radial direction, a screw rod is rotatably connected to the two bearing seats, guide rails are provided on both sides of the screw rod on the turntable, a second motor is installed on the outer end of the turntable, the second motor is transmission-connected to one end of the screw rod, a second slide is threadedly connected to the screw rod, the second slide is slidably connected to the guide rail, and the base is fixedly connected to the second slide.

[0012] The above technical solution starts the second motor, drives the screw to rotate, and thereby drives the second slide to move linearly along the guide rail, so that the positioning mechanism moves along the radial direction of the turntable to adjust the position of the positioning mechanism so that after the turntable rotates a certain number of times each time, the positioning mechanism can reach the bottom of the multi-hole drilling mechanism.

[0013] Preferably, the lifting mechanism includes a second cylinder installed on the extension platform and a second guide rod slidably connected to the extension platform, and the telescopic end of the second cylinder and the lower end of the second guide rod are both connected to the lifting plate.

[0016] In the above technical solution, after the flange is placed in the positioning groove, the third cylinder is controlled to extend, pushing the push-pull rod to rotate the pressure rod toward the flange until the pressure block presses the flange tightly in the positioning groove. Through the multiple sets of clamping mechanisms on the positioning cylinder, the flange can be stably fixed in the positioning groove.

[0017] Preferably, the second rotating mechanism includes a mounting base connected to one of the side panels, a third motor is mounted on the mounting base, the third motor is connected to a second transmission shaft via a coupling, a third gear is fixedly connected to the second transmission shaft, a fourth gear is fixedly connected to one of the rotating shafts, and the third gear is meshed with the fourth gear.

[0018] In the above technical solution, when the flange drilling on one side is completed, the third motor is started to drive the second transmission shaft to rotate, and the third gear and the fourth gear cooperate to drive the rotating shaft to rotate, thereby flipping the positioning cylinder to turn the other flange upward.

[0019] Preferably, a mounting groove is provided at the center of the top surface of the base, a fourth cylinder is installed in the mounting groove, a support plate is installed at the telescopic end of the fourth cylinder, and the support plate is located below the positioning cylinder.

[0020] In this technical solution, during drilling, the support plate contacts the bottom flange, thereby supporting the entire positioning cylinder and further improving drilling stability. Once the upper flange is drilled, the fourth cylinder retracts, moving the support plate away from the positioning cylinder and into the desired position, ensuring sufficient space for the positioning cylinder and flange to flip. Once the positioning cylinder flips, the fourth cylinder is controlled to extend, restoring the support plate to contact the bottom flange.

[0021] Preferably, a power button, a control button and a display are installed on the control cabinet, and a PLC programmable controller is provided in the control cabinet.

The PLC programmable controller is used to control the orderly operation of each module.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) Multiple positioning mechanisms are set on the turntable. By driving the turntable, the positioning mechanisms are moved one by one to the bottom of the multi-hole drilling mechanism, and the multi-hole drilling mechanism drills holes on the flange on the turntable one by one. Before each drilling, only one parameter adjustment is required to achieve batch drilling, with less manual intervention and high drilling efficiency.

[0025] (2) Two flanges can be fixed on the positioning tube. The two flanges are far away from each other and in a suspended state. The two flanges do not overlap, which will not increase the thickness of the drill hole and indirectly extend the working life of the drill rod. In addition, two flanges can be fixed on one positioning mechanism at the same time. When the drilling of one flange is completed, the positioning tube can be turned over to drill the other flange. In addition, the multi-hole drilling mechanism can drill multiple holes on a flange at the same time, further improving the drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1-6 A multi-station drilling device for flange processing includes a base 1, to which a rotating column 2 is rotatably connected via a rotating bearing. A first rotating mechanism 3 for controlling the rotation of the rotating column 2 is provided within the base 1, and a turntable 4 is fixedly connected to the upper end of the rotating column 2. Specifically, the first rotating mechanism 3 includes a first motor 301 installed within the base, a first transmission shaft connected to the first motor via a coupling, a first gear 302 fixedly connected to the first transmission shaft, and a second gear 303 fixedly connected to the rotating column, wherein the first gear 302 meshes with the second gear 303. When the first motor 301 is in operation, it drives the first transmission shaft to rotate, and through the cooperation of the first gear 302 and the second gear 303, it drives the rotating column 2 to rotate, thereby driving the turntable 4 to rotate.

[0035] The turntable 4 is provided with multiple sets of radial and concentric linear displacement mechanisms 5, each set of linear displacement mechanisms 5 being transmission-connected to a positioning mechanism 6 for positioning the flange. The flange is fixed by the positioning mechanism, and the turntable 4 is driven to rotate, which can drive the positioning mechanism 6 thereon to rotate together, thereby driving the flanges one by one to the drilling position. The linear displacement mechanism 5 can drive the positioning mechanism 6 thereon to perform linear motion along the radial direction of the turntable. Specifically, the linear displacement mechanism 5 includes two bearing seats 501 fixed to the turntable 4 and arranged along its radius. A screw rod 502 is rotationally connected to the two bearing seats 501. Guide rails 503 are provided on both sides of the screw rod on the turntable 4. A second motor 504 is mounted on the outer end of the turntable 4, which is transmission-connected to one end of the screw rod 502. A second slide 505 is threadedly connected to the screw rod 502, and the second slide 505 is slidably connected to the guide rail 503. A base 601 is fixedly connected to the second slide 505. The second motor 504 rotates the lead screw 502, thereby driving the second slide 505 to move linearly along the guide rail 503, thereby moving the positioning mechanism 6 in the radial direction of the turntable 4, thereby adjusting the position of the positioning mechanism. Specifically, matching position sensors can be installed at the center of the polygonal block and the support plate. Through the cooperation of these two position sensors, the positioning mechanism 6 is aligned with the multi-hole drilling mechanism 9. After the position of one set of positioning mechanisms 6 is adjusted, the turntable 4 is controlled to rotate so that another set of positioning mechanisms 6 is positioned below the multi-hole drilling mechanism 9. The position of the other set of positioning mechanisms 6 is then adjusted by the action of another linear displacement mechanism 5 until all positioning mechanisms 6 are aligned with the multi-hole drilling mechanism 9, completing the adjustment.

[0036] The positioning mechanism 6 includes a base 601, which is fixedly connected to the second slide 505. Side plates 602 are fixedly connected to both ends of the base 601. Rotating shafts 603 are rotatably connected to both side plates 602 through rotating bearings. A positioning cylinder 604 that passes through the two rotating shafts 603 is fixedly connected. Positioning grooves 605 are provided at the upper and lower ends of the positioning cylinder 604. Several clamping mechanisms are installed on the outer walls of both ends of the positioning cylinder 604, and the flanges are pressed tightly into the positioning grooves 605 through the clamping mechanisms. Specifically, the clamping mechanism includes a lifting ear 606 fixedly connected to the outer wall of the end of the positioning cylinder 604, and a third cylinder 607 is installed on the bottom surface of the lifting ear 606. The top of the lifting ear 606 is fixedly connected to a support rod 608 near the end of the positioning cylinder, and a connecting rod 609 is pivoted on the support rod 608. The telescopic end of the third cylinder 607 is connected to a push-pull rod 610, and a pressure rod 611 is pivoted on the push-pull rod 610. The end of the connecting rod 609 away from the support rod is pivoted to the pressure rod 611, and the bottom surface of the pressure rod 611 away from the push-pull rod is connected to a pressure block 612. Rotating the pressure rod 611 can cause the pressure block 612 to rotate toward the positioning groove 605. After the flange is placed in the positioning groove 605, the third cylinder 607 is controlled to extend, pushing the push-pull rod 610, so that the pressure rod 611 rotates toward the flange until the pressure block 612 presses the flange tightly in the positioning groove 605. Through the multiple sets of pressing mechanisms on the positioning cylinder 604, the flange can be stably fixed in the positioning groove 605.

[0037] A second rotating mechanism is mounted on one of the side panels 602 to drive the rotating shaft. This second rotating mechanism can drive the rotating shaft to rotate, thereby causing the positioning tube to flip. The second rotating mechanism includes a mounting base 613 connected to one of the side panels 602. A third motor 614 is mounted on the mounting base 613. The third motor 614 is connected to a second transmission shaft via a coupling. A third gear 615 is fixedly connected to the second transmission shaft. A fourth gear 616 is fixedly connected to one of the rotating shafts 603, and the third gear 615 meshes with the fourth gear 616. Activating the third motor 614 rotates the second transmission shaft. The third gear 615 and the fourth gear 616 engage with each other, thereby causing the positioning tube 604 to flip.

[0038] A control cabinet 7 is provided on one side of the base 1, and an extension platform extending toward the base is fixedly connected to the upper part of the control cabinet 7, and a lifting mechanism 8 is installed on the extension platform, and a multi-hole drilling mechanism 9 is installed on the lifting mechanism 8. The lifting mechanism 8 includes a second cylinder 801 installed on the extension platform and a second guide rod 802 slidably connected to the extension platform. The telescopic end of the second cylinder 801 and the lower end of the second guide rod 802 are both connected to the lifting plate 901. The multi-hole drilling mechanism 9 includes a lifting plate 901, which is connected to the lifting mechanism 8. A polygonal block 902 is fixedly connected to the center of the bottom surface of the lifting plate 901. A plurality of connecting plates 903 corresponding to the edges of the polygonal block 902 are fixed to the periphery of the lifting plate 901. First guide rods 904 are connected to the connecting plates 903 and the corresponding edges. A first slide 905 is slidably connected to the first guide rods 904. A drilling rig 906 is mounted on the bottom surface of the first slide 905. A first cylinder 907 is mounted on the outer side of each connecting plate 903. The telescopic end of the first cylinder 907 passes through the connecting plate and is connected to the first slide 905. The lifting mechanism 8 operates to lower the lifting plate 901, allowing the drill rod to contact the flange, thereby completing the drilling operation. The operation of the first cylinder 907 drives the first slide 905 on the first guide rod 904, thereby adjusting the position of the drilling rig to adjust the position according to the radius of the flange. During the specific operation, the position of each drill rig can be adjusted one by one. After each adjustment of the position of a drill rig, the distance between the drill rig and the center of the polygonal block is measured with a ruler until the distance between all drill rigs and the center of the polygonal block is equal, so as to facilitate subsequent batch drilling.

[0039] A mounting slot 617 is provided in the center of the top surface of the base 601. A fourth cylinder 618 is mounted within the mounting slot 617. A support plate 619 is connected to the telescopic end of the fourth cylinder 618. The support plate 619 is positioned below the positioning cylinder 604. During drilling, the support plate 619 contacts the bottom flange, thereby supporting the entire positioning cylinder 604 and further improving stability during drilling.

[0040] The control cabinet 7 is equipped with a power button, control buttons, and a display 10. A programmable logic controller (PLC) is housed within the control cabinet. The first motor 301, the second motor 504, the third motor 614, the first cylinder 907, the second cylinder 801, the third cylinder 607, the fourth cylinder 616, the drilling rig 906, the power button, the control buttons, and the display 10 are all electrically connected to the PLC. The power button is used to start the entire equipment, the control buttons are used to control the operation of the corresponding components, and the touch-sensitive display can be used to input various parameters and view the operating status and parameters of each component. The PLC is used to control the orderly operation of each module.

[0041] The working principle of the present invention is:

[0042] After the equipment is debugged and all parameters are entered, the flanges 11 are installed one by one in the positioning grooves 605 at both ends of the positioning cylinder 604, and then the flanges are pressed tightly in the positioning grooves 605 through the clamping mechanism. Then the fourth cylinder 617 extends, driving the support plate 618 to extend to support the positioning cylinder 604. Then the multi-hole drilling mechanism 9 is controlled to descend through the lifting mechanism 8, and all drilling rigs 906 are started to drill holes in the flanges on the positioning cylinder. When the drilling of the upper flange is completed, the fourth cylinder 617 contracts to move the support plate away from the positioning cylinder and reach the required position so that the positioning cylinder and the flange have enough space to flip over. Then the positioning cylinder 604 is controlled to flip so that the undrilled flange faces, and then the fourth cylinder is controlled to extend so that the support plate contacts the bottom flange again, and the new flange is drilled through the multi-hole drilling mechanism. When the drilling of the two flanges on the positioning mechanism is completed, the turntable 4 is driven to rotate so that the positioning mechanisms 6 on the turntable 4 reach the bottom of the multi-hole drilling mechanism one by one, and the flanges on the positioning mechanism are drilled one by one by the multi-hole drilling mechanism. While drilling, workers can install new flanges on other positioning mechanisms to achieve drilling while loading, thereby improving drilling efficiency.
