Description

Technical Field

[0001] This utility model belongs to the field of flange processing, specifically a high-efficiency processing device for wind power flanges. Background Technology

[0002] As a key connecting component of wind turbine generators, wind turbine flanges typically require multiple high-precision bolt holes to be machined in the circumferential direction to meet assembly requirements. Currently, traditional wind turbine flange drilling equipment mainly relies on mechanical clamps to hold the flange rings, and drives the clamps and flange rings to rotate via drive equipment (such as servo motors or hydraulic rotary tables), while a single drilling machine completes the drilling process one by one.

[0003] However, in actual processing, traditional mechanical clamps (such as multiple hydraulic clamping mechanisms clamping simultaneously) struggle to apply uniform force when clamping large flange rings. This results in slight displacement of the flange during rotation due to the combined effects of centrifugal force and vibration, making it difficult to guarantee the accuracy of subsequent drilling. Furthermore, traditional equipment is equipped with only a single drilling machine, requiring the bolt holes on the flange to be processed one by one, significantly extending the processing cycle and causing low equipment utilization. Utility Model Content

[0005] A high-efficiency processing device for wind turbine flanges includes a base with a worktable. The worktable includes a placement plate for placing flanges. A positioning component is located at the center of the placement plate. The positioning component includes several positioning blocks that can move radially along the placement plate. The positioning blocks are connected by the same synchronization mechanism for driving the flange ring to move and complete automatic positioning and clamping. A rotating component is located on the outer side of the placement plate on the base. The rotating component includes an annular guide rail that can rotate circumferentially along the placement plate. Several drilling components are located on the annular guide rail.

[0008] Preferably, a stepper motor is driven to the rotating disk.

[0009] Preferably, a plurality of guide blocks are slidably sleeved on the annular guide rail, and the guide blocks are fixedly connected to the base. An internal gear ring is provided on the inner side of the annular guide rail, and a drive gear that cooperates with the internal gear ring is rotatably provided on the inner side of the guide block on the base.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] As attached Figure 1 To be continued Figure 3 As shown:

[0023] This utility model provides a high-efficiency processing device for wind turbine flanges, including a base 1, a worktable 4, a positioning component 5, a rotating component 2, and a drilling component 3. The base 1 is made of high-strength steel and formed by welding or casting processes, with pre-drilled mounting holes and slots for each component to ensure installation accuracy and stability.

[0024] As attached Figure 1 To be continued Figure 2 As shown: The workbench 4 is mounted on the base 1 and consists of a placement plate 401, a guide sleeve 402, and ball bearings 8. The placement plate 401 has grooves and sliding grooves machined on its surface. Ball bearings 8 are rolled within the grooves. When the wind turbine flange is placed on the placement plate 401, the ball bearings 8 provide support and assist in movement, greatly reducing friction during flange placement and movement, and facilitating adjustment of the flange's initial position. A guide sleeve 402 is circumferentially mounted on the bottom surface of the placement plate 401. The guide sleeve 402 is fixed to the bottom surface of the placement plate 401 by welding or bolts, providing guidance for the connecting rod 503 and ensuring its stability during movement. Simultaneously, the sliding groove on the placement plate 401 slides in conjunction with the positioning block 504, ensuring the positioning block 504's accurate orientation during movement and guaranteeing precise positioning of the wind turbine flange.

[0025] As attached Figure 1 To be continued Figure 2As shown: The positioning assembly 5 is located at the center of the placement plate 401 and consists of a rotating disk 501, a slider 502, a connecting rod 503, a positioning block 504, and a stepper motor 6. The rotating disk 501 is rotatably positioned in the middle of the placement plate 401 and is rotatably connected to the placement plate 401 through bearings, ensuring that the rotating disk 501 can rotate smoothly. Several arc-shaped guide grooves are machined on the rotating disk 501, and the slider 502 slides in the arc-shaped guide grooves. This connection method allows the rotation of the rotating disk 501 to be converted into the radial movement of the slider 502. One end of the connecting rod 503 is fixedly connected to the slider 502, and the other end passes through the guide sleeve 402 and is fixedly connected to the positioning block 504, thereby transmitting the movement of the slider 502 to the positioning block 504. The stepper motor 6 is connected to the rotating disk 501 through a coupling, providing power for the rotation of the rotating disk 501. When the stepper motor 6 starts, it drives the rotating disk 501 to rotate. The arc-shaped guide groove on the rotating disk 501 drives the slider 502 to slide within the arc-shaped guide groove. The slider 502 drives the positioning block 504 to move radially within the groove of the placement plate 401 through the connecting rod 503. Since multiple positioning blocks 504 are connected by a synchronization mechanism, they move towards the flange ring simultaneously, automatically positioning and clamping the flange ring at the center of the placement plate 401, realizing rapid automatic positioning and clamping of the wind turbine flange, improving positioning accuracy and efficiency.

[0026] As attached Figure 1 To be continued Figure 2 As shown: The rotating assembly 2 is mounted on the outer side of the placement plate 401 on the base 1, and consists of an annular guide rail 202, a guide block 201, an internal gear ring 203, a drive gear 204, and a stepper motor. The annular guide rail 202 is slidably fitted onto the guide block 201, and the guide block 201 is fixedly connected to the base 1 by bolts. This connection method ensures the stability of the annular guide rail 202 during rotation and prevents it from shaking or shifting. The internal gear ring 203 is fixed to the inner side of the annular guide rail 202 by welding or bolting. The drive gear 204 is rotatably mounted on the inner side of the guide block 201 on the base 1 and works in conjunction with the internal gear ring 203. The shaft of the drive gear 204 is connected to the output shaft of the stepper motor through a gearbox. When the stepper motor starts, the drive gear 204 rotates, driving the internal gear ring 203 and the annular guide rail 202 to rotate circumferentially along the placement plate 401. This design enables the annular guide rail 202 to rotate precisely along a predetermined trajectory, providing stable support and guidance for the circumferential movement of the drilling assembly 3.

[0027] As attached Figure 1 To be continued Figure 3As shown: The drilling assembly 3 is mounted on the annular guide rail 202 and consists of a bracket 301, a two-axis feed system 302, and a drilling machine 303. The bracket 301 is fixed to the annular guide rail 202 by welding or bolting and rotates synchronously with the rotation of the annular guide rail 202. The two-axis feed system 302 is located between the bracket 301 and the drilling machine 303 and includes a screw 3021, a mounting plate 3022, a telescopic cylinder 3023, and a guide rod 7.

[0028] The screw 3021 is mounted on the bracket 301 via a bearing drive, and its end is connected to the mounting plate 3022. When the screw 3021 rotates, it drives the mounting plate 3022 to move along the bracket 301, realizing the radial movement of the drilling machine 303. A telescopic cylinder 3023 is fixedly mounted on the mounting plate 3022. The movable end of the telescopic cylinder 3023 is fixedly connected to the mounting bracket of the drilling machine 303, and the extension and retraction of the telescopic cylinder 3023 drives the drilling machine 303 to move axially. A guide rod 7 is also fixedly mounted on the mounting plate 3022. The end of the guide rod 7 passes through the bracket 301 and is slidably connected to the bracket 301. The guide rod 7 guides the movement of the mounting plate 3022, ensuring the stability of the drilling machine 303 in axial and radial movement and further improving the processing quality.

[0029] Multiple drilling components 3 are equidistantly arranged on the annular guide rail 202, allowing simultaneous drilling of the flange ring. The rotation of the annular guide rail 202, the movement of the dual-axis feed system 302, and the automatic alignment and centering of the flange ring by the positioning component 5 work together to effectively ensure machining accuracy and greatly improve machining efficiency.

[0030] Working principle:

[0031] Workers use a crane to place the wind turbine flange onto the placement plate 401. The ball bearings 8 provide support and assist in movement, facilitating initial flange position adjustment. The stepper motor 6 is then started, driving the rotating disk 501 to rotate. The arc-shaped guide groove on the rotating disk 501 causes the slider 502 to slide within the groove. The slider 502, via the connecting rod 503, drives the positioning block 504 to move radially within the groove of the placement plate 401. Because multiple positioning blocks 504 are connected by a synchronization mechanism, they move simultaneously towards the flange ring, automatically positioning and clamping the flange ring at the center position of the placement plate 401 and the annular guide rail 202.

[0032] The stepper motor, connected to the drive gear 204, is started, causing the annular guide rail 202 to rotate circumferentially along the placement plate 401. Simultaneously, the dual-axis feed system 302 begins operation; the screw 3021 rotates, causing the mounting plate 3022 to move along the bracket 301, thus enabling the drilling machine 303 to move radially; the telescopic cylinder 3023 extends and retracts, causing the drilling machine 303 to move axially. Multiple drilling components 3 simultaneously drill holes in the flange ring, and the positioning component 5 automatically aligns and centers the flange ring, ensuring machining accuracy and improving machining efficiency.

Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
