Description

Technical Field

[0001] This utility model relates to the field of wind power equipment manufacturing technology, specifically a drilling device for balsa wood core sleeves for wind turbine blades. Background Technology

[0002] In the wind turbine blade manufacturing process, balsa wood sandwich panels need to go through core processes such as cutting, drilling, bonding, and curing. Among them, the drilling process is a key step to ensure the effective connection between the panel and the blade shell and web. After drilling, the panel needs to be fixed to other structural components by bolts, rivets, or resin injection. The accuracy of the hole position and the integrity of the hole wall directly affect the connection strength. If the hole position is deviated or the hole wall is cracked or burr-like, it may cause stress concentration during blade operation and lead to structural failure risk. Therefore, the accuracy of the hole position of the balsa wood sandwich panel directly determines the aerodynamic performance and service life of the blade.

[0003] While existing technologies meet user needs to a certain extent, certain shortcomings still exist during use. Specific problems include: traditional balsa wood drilling often employs a general-purpose bench drill combined with manual adjustment or a simple CNC drilling machine. General-purpose bench drills rely on manual positioning, resulting in generally high hole position errors, failing to meet the stringent precision requirements of wind turbine blades. Simple CNC drilling machines, while possessing basic automation functions, often use belt drives and single-axis guidance in their transmission systems, lacking anti-deflection constraint structures. The balsa wood core material is brittle, and vibrations during transmission can easily cause hole wall cracking. Furthermore, the equipment only supports processing single-specification sleeves; changing blade models requires re-adjusting the fixture, leading to long adjustment times and low equipment compatibility. Therefore, this invention designs a drilling device for balsa wood core sleeves for wind turbine blades to solve the aforementioned problems. Utility Model Content

A movable seat limiting groove 32 that matches the movable seat limiting block 31 is opened on the surface of the transverse slide beam 21. A transverse transmission screw 33 is threadedly connected to the surface of the movable seat limiting block 31. The transverse transmission screw 33 is rotatably connected to the transverse slide beam 21 through the movable seat limiting groove 32. A transverse drive motor 34 is installed on the surface of the supporting columns 2, and the output shaft of the transverse drive motor 34 is fixedly connected to the transverse transmission screw 33.

[0021] In this implementation scheme: When the transverse drive motor 34 is powered on, the output shaft drives the transverse transmission screw 33 to rotate. The moving seat limit block 31 on the drilling moving seat 3 engages with the transverse transmission screw 33 by thread. At the same time, the moving seat limit block 31 is embedded in the moving seat limit groove 32 of the transverse slide beam 21, which converts the rotational motion of the screw into the linear sliding of the drilling moving seat 3 along the transverse slide beam 21. The drilling actuator 4 moves laterally synchronously with the drilling moving seat 3 to realize the lateral adjustment of the drilling position.

[0022] Furthermore:

[0023] In an optional embodiment, a motor mounting base 35 is fixedly connected to the surface of the support column 2, and the surface of the motor mounting base 35 is provided with a mounting groove that cooperates with the transverse drive motor 34.

[0024] In this embodiment, the mounting groove on the surface of the motor mounting base 35 is adapted to the shape of the transverse drive motor 34, providing a stable installation for the motor, preventing it from loosening due to vibration during operation, and ensuring the stable drive of the transverse transmission screw 33.

[0025] Furthermore:

[0026] In an optional embodiment, a longitudinal adjustment frame 5 is fixedly connected to the surface of the punching moving base 3. A longitudinal sliding block 51 is provided on the surface of the longitudinal adjustment frame 5. A longitudinal guide groove 52 that cooperates with the longitudinal sliding block 51 is opened on the surface of the longitudinal adjustment frame 5. A punching actuator 4 is installed at the bottom end of the longitudinal adjustment frame 5.

[0027] In this embodiment: the longitudinal adjustment frame 5 is fixed to the surface of the drilling moving seat 3, and the longitudinal guide groove 52 opened therein accommodates the longitudinal sliding block 51, which builds a bearing frame for the longitudinal displacement of the drilling actuator 4. The longitudinal adjustment frame 5 is arranged perpendicular to the drilling moving seat 3, so that the drilling actuator 4 has both lateral and longitudinal displacement degrees of freedom, covering a wider drilling area.

[0028] Furthermore:

[0029] In an optional embodiment, the surface of the longitudinal sliding block 51 is threadedly connected to a longitudinal transmission screw 6, the longitudinal transmission screw 6 is rotatably connected to the longitudinal adjusting frame 5 through a longitudinal guide groove 52, and a longitudinal drive motor 61 is installed inside the longitudinal adjusting frame 5, the output shaft of the longitudinal drive motor 61 is fixedly connected to the longitudinal transmission screw 6.

[0030] In this embodiment: the longitudinal drive motor 61 is powered on and operates, and the output shaft drives the longitudinal transmission screw 6 to rotate. The longitudinal sliding block 51 is threadedly engaged with the longitudinal transmission screw 6 and embedded in the longitudinal guide groove 52 of the longitudinal adjustment frame 5, which converts the rotational motion of the screw into the linear sliding of the longitudinal sliding block 51 along the longitudinal guide groove 52. The drilling actuator 4 moves longitudinally synchronously with the longitudinal sliding block 51 to realize the longitudinal adjustment of the drilling position.

[0031] Furthermore:

[0033] In this embodiment: the clamp drive motor 81 is powered on and operates, and the output shaft drives the clamp transmission screw 8 to rotate. The clamp sliding seat 71 at the bottom of the core sleeve clamping block 7 is threadedly engaged with the clamp transmission screw 8 and embedded in the clamp guide groove 72 of the equipment base 1. The rotational motion of the screw is converted into the linear sliding of the core sleeve clamping block 7 along the clamp guide groove 72. The symmetrically arranged core sleeve clamping blocks 7 move closer / away simultaneously to complete the clamping, loosening and position adjustment of the balsa core sleeve. With the self-locking characteristic of the screw, it is ensured that there is no slippage when drilling holes in the sleeve.
