To achieve connection and sealing, flanges must be drilled. Positioning the holes is a critical step, directly affecting the accuracy of the holes and the effectiveness of the flange connection.

[0003] Currently, accurate positioning of flange holes is achieved through the location and number of holes, as well as manual marking. For example, the flange diameter is manually divided into several equal sections; or tools (such as indexers and dividers) or calculations are used to mark each section to ensure the accuracy of each section for subsequent drilling. However, this manual positioning and drilling method is time-consuming and labor-intensive, and is prone to errors. Consequently, the accuracy and position of the holes cannot be guaranteed, resulting in excessive gaps after connection, affecting the stability of the connection.

[0004] Therefore, there is an urgent need in the art for a positioning device that saves time and effort and can ensure the positional precision and accuracy of flange drilling. Summary of the Invention

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] The utility model provides a positioning device for drilling a flange, such as Figure 1-Figure 3 As shown, the device comprises a support and a rotating body. The rotating body comprises a turntable 11 and a rotating seat 12 connected to each other. The support body comprises a base 7 and a support column 8 connected to each other. The base 7 is placed on the ground to support the entire positioning device. The top surface of the support column 8 is provided with a first groove 9. The rotating seat 12 matches the first groove 9, so that the rotating seat 12 is rotatably connected to the first groove 9, enabling the rotating seat 12 to rotate within the support column, thereby achieving a rotational connection between the rotating body and the support body. A workbench 1 is fixedly mounted on the top surface of the turntable 11 and is used to place the flange to be punched. A servo motor 2 is fixedly connected to the support column 8 via a first support member 10. The output shaft of the servo motor 2 is fixedly connected to a gear 4, which meshes with a rotating support 5. The rotating support 5 is fixedly mounted on the outside of the rotating body, so that rotation of the output shaft of the servo motor 2 drives the rotation of the gear 4, which in turn drives the rotation of the rotating support 5, which in turn drives the rotation of the rotating body, which in turn drives the rotation of the workbench 1. The rotation of the workbench 1 drives the rotation of the flange to be punched. The servo motor 2 is connected to the encoder 3, which records the angular displacement of the output shaft of the servo motor 2 in real time. The encoder 3 and the servo motor 2 are both connected to the control box 6, so that the encoder 3 feeds back the recorded angular displacement of the output shaft of the servo motor 2 to the control box 6, and the control box 6 then controls the start and stop of the servo motor 2.

[0028] The positioning device for drilling a flange provided by the present invention can, in a specific application process, operate the control box 6 after the flange is fixed on the workbench 1 . The control box 6 is provided with selection gears for the number of holes to be punched and the diameter of the holes to be punched. After selecting the corresponding preset value of the number of holes to be punched and the preset value of the hole diameter to be punched according to actual needs, the control box 6 will convert the preset value of the number of holes to be punched and the preset value of the hole diameter to be punched into a preset angular displacement between the two holes, and then feed back the signal of the preset angular displacement between the two holes to the encoder 3. At the same time, the control box 6 feeds back the driving signal to the servo motor 2. After receiving the driving signal, the servo motor 2 will drive the output shaft of the servo motor 2 to rotate, and through the gear 4, the slewing support 5, and the workbench 1, the flange will rotate accordingly. The encoder 3 will record the angular displacement of the output shaft of the servo motor 2 in real time. When the angular displacement of the output shaft of the servo motor 2 is equal to the preset angular displacement between the two holes, the encoder 3 will feed back the signal to the control box 6. The control box 6 will transmit a stop drive signal to the servo motor 2, thereby stopping the servo motor 2 from driving, and the output shaft will no longer rotate. The flange on the workbench 1 will also stop rotating, and then the punching device (not shown) above the flange is started to punch the flange.

[0029] This positioning device is provided with a control box 6 of a solidified program or PLC type. When the operator determines the number and diameter of the holes to be punched and other parameters, the operator can select the corresponding gear by controlling the position on the control box 6. When the output shaft of the servo motor 2 rotates, it will drive the synchronous rotation of the flange on the workbench 1. Therefore, the precise positioning of the angular displacement of the flange only requires the precise positioning of the angular displacement of the output shaft of the servo motor 2. When the angular displacement of the output shaft of the servo motor 2 matches the preset angular displacement, the encoder 3 will feed back the signal to the control box 6. The control box 6 sends a stop drive signal to stop the servo motor 2, so that the flange rotates to the preset position, thereby achieving precise positioning of the flange rotation, saving time and strength, and convenient operation, thereby improving the efficiency of punching holes in the flange.

[0030] In this embodiment, two second grooves 13 are provided on the sidewall of the support column 8, and the diameter of the workbench 1 where the two second grooves 13 are located is approximately perpendicular to the diameter of the workbench 1 where the servo motor 2 is located. The second grooves 13 are connected to the first groove 9, and the horizontal height of the lower end of the second groove 13 is greater than the horizontal height of the lower end of the first groove 9, so that the horizontal height of the servo motor 2 is greater than the horizontal height of the support column 8. The opening of the second groove 13 is covered with a cylinder housing 14, and a first cylinder 15 is connected to the cylinder housing 14. The first cylinder 15 is connected to the control box 6. The fixed end of the first cylinder 15 is connected to the sidewall of the cylinder housing 14, and the movable end of the first cylinder 15 is connected to a locking member 16. The locking member 16 is used to hold the support column 8 so that the support column 8 can stop rotating more accurately at a preset position. One end of the locking member 16 is hinged to the movable end of the first cylinder 15, and the other end of the locking member 16 is hinged to the support column 8. The locking member 16 includes a shoe portion 17 and a connecting rod portion 18 that are hinged to each other. The shoe portion 17 is arc-shaped and matches the side wall of the rotating seat 12. The end of the connecting rod portion 18 is hinged to the support column 8.

[0031] Specifically, by operating the control box 6, when the flange is rotated to a preset displacement, the encoder 3 is fed back to the control box 6, and the control box 6 sends a stop drive signal to stop the servo motor 2 from driving. At the same time, the control box 6 also sends a start signal to the first cylinder 15, thereby driving the first cylinder 15 to move. The movable ends of the two first cylinders 15 move toward each other, and the movable ends will push the shoe 17 to abut against and hold the support column 8, further stopping the support column 8 from rotating, thereby further ensuring the precise positioning of the flange.

[0032] In this embodiment, a second support member 19 is fixedly connected to the side wall of the support column 8. The second support member 19 is connected to a second cylinder 20. The second cylinder 20 is used to apply upward pressure to the flange on the workbench 1 to prevent the flange from deviating. The second cylinder 20 is connected to the control box 6. The fixed end of the second cylinder 20 is connected to the support arm, and the movable end of the second cylinder 20 is connected to the turntable 11. The control box 6 is arranged on the side wall of the support column 8. Specifically, the punching device above the flange is located opposite the second cylinder 20. When the punching device punches holes in the flange, it will exert downward pressure on the flange, which may cause the flange to deviate. In this device, by arranging the second cylinder 20 in a direction opposite to the punching device, the control box 6 sends a signal to stop the drive servo motor 2 and start the first cylinder 15. At the same time, the second cylinder 20 is started, exerting upward pressure on the flange to ensure balanced force on the upper and lower parts of the flange, prevent the flange from deviating, and improve the positioning accuracy and punching accuracy of the flange.

[0033] In this embodiment, a plurality of support pads 21 are provided on the top surface of the workbench 1. The support pads 21 can support the flange on the workbench 1, so that a certain gap is formed between the flange and the workbench 1. This prevents the drilling device from causing damage to the workbench 1 when drilling, thereby protecting the workbench 1.

[0034] This utility model uses specific examples to illustrate the principles and implementation methods of this utility model. The above examples are only used to help understand the method and core concept of this utility model. At the same time, for those skilled in the art, according to the concept of this utility model, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
