Description

Technical Field

[0001] This utility model relates to the field of flange technology, and in particular, to a drilling device for flanges. Background Technology

[0002] A flange, also called a flange plate or flange, is a component used to connect pipes to each other, attached to the pipe ends. Flanges have holes, and bolts are used to secure two flanges together. A gasket is used for sealing between flanges. A flange is a disc-shaped component, most commonly found in piping engineering, and flanges are always used in pairs. In piping engineering, flanges are mainly used for connecting pipes. At the ends where two pipes need to be connected, a flange plate is installed on each. Low-pressure pipes can use threaded flanges, while welded flanges are used for pressures above four kilograms. A gasket is placed between the two flange plates, and then they are tightened with bolts. Poor positioning accuracy during flange hole machining results in unevenly distributed holes, compromising quality. Furthermore, fixing the flanges during machining is cumbersome, affecting processing efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a drilling device for flanges with high drilling positioning accuracy and high processing efficiency.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a drilling device for flanges, used for drilling flanges. The drilling device for flanges includes a base, a mounting plate rotatably mounted on the base, a mounting frame, a fixing component mounted on the mounting plate, and a drilling component mounted on the mounting frame. The fixing component includes a pusher, a conical block connected to the pusher, a moving rod cooperating with the conical block, and a holding block connected to the conical block. The holding block abuts against the flange. The drilling component includes a cylinder mounted on the mounting frame, a drive motor connected to the extended end of the cylinder, a circular plate connected to the output shaft of the drive motor, and two electric drill bits movably mounted on the circular plate, with the two electric drill bits being close to or far from each other on the circular plate.

[0005] Furthermore, the drilling assembly also includes a rotating component, a guide bar, a bidirectional threaded rod, and a sliding block. The guide bar is fixedly mounted on the circular plate, and the output shaft of the drive motor passes through the circular plate. The bidirectional threaded rod is rotatably mounted on the output shaft of the drive motor. There are two sliding blocks, both of which are slidably engaged with the guide bar and threadedly connected to the bidirectional threaded rod. The rotating component is fixedly connected to one end of the bidirectional threaded rod, and the electric drill bit is located at the bottom of the sliding block.

[0006] Furthermore, the center of the circular plate and the center of the conical block are on the same longitudinal line.

[0007] Furthermore, there are multiple moving rods and multiple supporting blocks. Each of the multiple moving rods cooperates with the conical block. The end of the moving rod near the conical block is provided with a supporting surface, which abuts against the inclined surface of the conical block.

[0008] Furthermore, the actuating component is a cylinder.

[0009] Furthermore, the guide strip is provided with scale lines.

[0010] Furthermore, the rotating component is a rocker arm.

[0011] Furthermore, a rotating motor is provided on the base, and the output shaft of the rotating motor is fixedly connected to the mounting plate.

[0012] The beneficial effects of this utility model are as follows: The flange drilling device provided by this utility model uses two electric drill bits that move closer or further apart until they reach a suitable position. Then, the cylinder is activated, causing the electric drill bits to descend to two of the flange's hole positions. The electric drill bits then drill holes in the flange. Finally, the cylinder rises, activating the drive motor. The drive motor rotates the circular plate by a certain angle, which in turn rotates the electric drill bits by a certain angle. The cylinder then descends again to the other two hole positions on the flange, and the electric drill bits drill holes in the flange. This cycle continues until all the hole positions on the flange have been drilled, resulting in high drilling position accuracy. Simultaneously, the pushing component causes the conical block to slide upwards, allowing the moving rod to slide away from the conical block. This allows the holding block to abut against the inner ring of the flange, thus fixing the flange. Therefore, the flange fixing operation is simple and the processing efficiency is high.

[0017] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0018] Please see Figure 1 and Figure 2 This utility model provides a flange drilling device for drilling flanges. The flange drilling device includes a base 1, a mounting plate 2, a mounting bracket 3, a fixing component 4, and a drilling component 5. The mounting plate 2 is rotatably mounted on the base 1, the fixing component 4 is mounted on the mounting plate 2, and the drilling component 5 is mounted on the mounting bracket 3. In use, the mounting plate 2 is first rotated so that the flange to be drilled is directly below the drilling component 5. Then, the fixing component 4 fixes the flange, and finally, the drilling component 5 descends to drill holes in the flange.

[0019] A rotating motor 11 is mounted on the base 1, and the output shaft of the rotating motor 11 is fixedly connected to the mounting plate 2. In use, the rotating motor 11 is started, and the rotating motor 11 drives the mounting plate 2 to rotate.

[0020] The fixing assembly 4 includes a pushing member 41, a conical block 42, a moving rod 43, and a supporting block 44. The pushing member 41 is fixedly mounted on the mounting plate 2. The conical block 42 is fixedly connected to the extended end of the pushing member 41. The moving rod 43 is slidably mounted on the mounting plate 2, and the conical block 42 and the moving rod 43 cooperate with each other. The supporting block 44 has an arc-shaped plate structure and is fixedly connected to the moving rod 43, abutting against the flange. Furthermore, there are multiple moving rods 43 and multiple supporting blocks 44. Each moving rod 43 cooperates with the conical block 42. The end of the moving rod 43 near the conical block 42 is provided with a supporting surface 431, which abuts against the inclined surface of the conical block 42. This allows the moving rod 43 to slide away from the conical block 42 when the conical block 42 slides upward.

[0021] In this embodiment, the pusher 41 is a cylinder. In other embodiments not shown, the pusher 41 may also be an electric push rod. In use, the pusher 41 is activated, causing the conical block 42 to slide upward, thereby allowing the moving rod 43 to slide away from the pusher 41, which in turn allows the abutment block 44 to abut against the inner ring of the flange, thus fixing the flange.

[0022] To allow the abutment block 44 to slide back and forth on the mounting plate 2, a fixing rod (not shown) is provided on the mounting plate 2, and the fixing rod is located on one side of the moving rod 43. A spring (not shown) is provided between the fixing rod and the abutment block 44. In use, the pusher 41 drives the conical block 42 to slide downward, thereby allowing the moving rod 43 to slide closer to the pusher 41, which in turn allows the flange to disengage from the abutment block 44.

[0023] The drilling assembly 5 includes a cylinder 51, a drive motor 52, a circular plate 53, a rotating component 54, a guide bar 55, a bidirectional threaded rod 56, a sliding block 57, and an electric drill bit 58. The cylinder 51 is fixedly mounted on the mounting bracket 3. The drive motor 52 is fixedly connected to the extended end of the cylinder 51. The circular plate 53 is fixedly connected to the output shaft of the drive motor 52. The center of the circular plate 53 and the center of the conical block 42 are on the same longitudinal line, and the output shaft of the drive motor 52 passes through the circular plate 53. The guide bar 55 is fixedly mounted on the circular plate 53. The bidirectional threaded rod 56 is rotatably mounted on the output shaft of the drive motor 52. There are two sliding blocks 57 and two electric drill bits 58. The two sliding blocks 57 are slidably engaged with the guide bar 55, and the sliding blocks 57 are threadedly connected to the bidirectional threaded rod 56. The rotating component 54 is fixedly connected to one end of the bidirectional threaded rod 56. The electric drill bit 58 is located at the bottom of the sliding block 57. In use, first rotate the rotating component 54, causing the sliding block 57 to slide on the bidirectional threaded rod 56, thereby causing the two electric drill bits 58 to move closer or further apart until the electric drill bits 58 move to a suitable position. Then, start the cylinder 51, causing the electric drill bits 58 to descend to two of the positions to be drilled on the flange. Then, start the electric drill bits 58 to drill holes in the flange. Finally, the cylinder 51 rises, starting the drive motor 52. The drive motor 52 drives the circular plate 53 and the bidirectional threaded rod 56 to rotate at a certain angle, which in turn drives the electric drill bits 58 to rotate at a certain angle. The cylinder 51 descends again to the other two positions to be drilled on the flange, and the electric drill bits 58 are started to drill holes in the flange. This cycle is repeated until all the positions to be drilled on the flange have been drilled.

[0024] In this embodiment, the rotating element 54 is a rocker arm. In other embodiments not shown, the rotating element 54 may also be a motor or a rotating wheel.

[0025] Furthermore, the guide bar 55 is provided with scale lines (not shown in the figure), which can help the staff to quickly determine the position of the flange to be drilled.

[0026] In use, first place the flange to be drilled on the mounting plate 2, then activate the pusher 41. The pusher 41 drives the conical block 42 to slide upward, thereby allowing the moving rod 43 to slide away from the conical block 42. This allows the holding block 44 to abut against the inner ring of the flange, thus fixing the flange. Then, activate the rotary motor 11, which drives the mounting plate 2 to rotate. Next, rotate the rotating component 54, causing the sliding block 57 to slide on the bidirectional threaded rod 56, moving the two electric drill bits 58 to the appropriate position. Finally, activate the cylinder 51, causing the electric drill bits 58 to move to the appropriate position. The cylinder 51 descends to two of the positions to be drilled on the flange, and then the electric drill bit 58 is started. The electric drill bit 58 drills holes in the flange. Finally, the cylinder 51 rises and the drive motor 52 is started. The drive motor 52 drives the circular plate 53 and the bidirectional threaded rod 56 to rotate a certain angle, which in turn drives the electric drill bit 58 to rotate a certain angle. The cylinder 51 descends again to the other two positions to be drilled on the flange, and the electric drill bit 58 is started. The electric drill bit 58 drills holes in the flange. This cycle is repeated until all the positions to be drilled on the flange have been drilled.

[0027] The flange drilling device provided by this utility model involves two electric drill bits 58 moving closer or further apart until they reach a suitable position. Then, a cylinder 51 is activated, causing the electric drill bits 58 to descend to two of the desired drilling positions on the flange. The electric drill bits 58 then drill holes in the flange. Finally, the cylinder 51 rises, activating a drive motor 52. The drive motor 52 rotates a circular plate 53 by a certain angle, which in turn rotates the electric drill bits 58 by a certain angle. The cylinder 51 then descends again to the flange. At the other two drilling positions, the electric drill bit 58 is started to drill holes in the flange. This process is repeated until all drilling positions on the flange are drilled, resulting in high drilling positioning accuracy. At the same time, the pusher 41 drives the tapered block 42 to slide upward, which allows the moving rod 43 to slide away from the tapered block 42. This allows the holding block 44 to abut against the inner ring of the flange, thus fixing the flange. Therefore, the flange fixing operation is simple and the processing efficiency is high.
