Description

Technical Field

[0001] This utility model relates to the technical field of wind power equipment processing, and in particular to a laser scribing device for positioning the reinforcing ribs of a wind turbine nacelle. Background Technology

[0002] To ensure the strength and rigidity of the cabin canopy, a series of crisscrossing reinforcing ribs are usually installed on the inner wall of the canopy. Currently, the installation and positioning of the reinforcing ribs are achieved by manually marking lines beforehand. That is, the specific position of the reinforcing ribs is obtained by measurement, and then the lines are marked with a fine line dipped in ink.

[0003] The existing Chinese utility model patent with application number CN202020085131.5 relates to a laser scribing device for positioning the reinforcing ribs of a wind turbine nacelle, including a hanger, a rod, a mounting plate, a frame, a base, a side plate, a laser emitter, and a flip motor. It can switch the position of the laser lines on the nacelle nacelle by means of the flip motor to achieve the positioning of multiple reinforcing ribs, thereby improving the overall processing efficiency of the nacelle nacelle and achieving high stability of positioning accuracy.

[0004] However, in actual use, the above-mentioned device requires the motor cover to be moved, placed, and its position adjusted. Welding of reinforcing ribs is generally suitable for larger motor covers, and the moving and adjustment process requires a lot of time, equipment, and manpower. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a laser scribing device for positioning the reinforcing ribs of a wind turbine nacelle. The device can be fixed to the main body of the equipment on the motor cover by a fixing device, the working direction of the equipment can be adjusted by an adjusting device, and the working distance of the equipment can be adjusted by a telescopic device. This allows the equipment to be directly fixed on the inner surface of the workpiece, reducing the time consumed by handling and adjusting the position of the workpiece and improving the practicality of the device.

[0006] This utility model discloses a laser marking device for positioning the reinforcing ribs of a wind turbine nacelle; it includes a fixing device, an adjusting device, and a telescopic device. The adjusting device is installed on the fixing device, and the telescopic device is installed on the adjusting device. The fixing device fixes the main body of the device to the motor cover, the adjusting device adjusts the working direction of the device, and the telescopic device adjusts the working distance of the device, so that the device can be directly fixed on the inner surface of the workpiece, reducing the time consumed by handling and adjusting the position of the workpiece and improving the practicality of the device.

[0007] Preferably, the fixing device includes a frame, a suction cup, a quick connector, and supports. The suction cup is provided on the rear end face of the frame, the quick connector is installed on the side of the suction cup, and a set of supports is provided on the left and right sides of the inner front face of the suction cup. The air inside the suction cup is extracted by an external vacuum pump connected to the quick connector, so that the suction cup is adsorbed on the inner surface of the workpiece. The supports provide stable support by contacting the inner surface of the workpiece, reducing the vibration of the main body of the equipment caused by the air pressure fluctuation inside the suction cup during operation, and improving the practicality of the device.

[0008] Preferably, the adjusting device includes a bearing, a rotating seat, a nut, a bolt, a gripping rod, and anti-slip texture. A bearing is mounted on the front face of the frame, and the rotating seat is inserted into the inner ring of the bearing. A bracket is mounted on the side of the frame, and a bolt is connected to the bracket via a nut. A gripping rod is connected to the outer surface of the bolt, and anti-slip texture is provided on the outer surface of the rotating seat. Due to limitations in the equipment's installation location, rotating the rotating seat adjusts the main working angle of the equipment. Rotating the bolt causes it to press against the side of the rotating seat, thus fixing the working angle. The anti-slip texture on the side of the rotating seat increases the coefficient of friction between the bolt and the side of the rotating seat. The gripping rod facilitates manual rotation of the bolt by the operator, improving the device's practicality.

[0009] Preferably, the telescopic device includes a damping pivot seat, a rotating arm, a telescopic arm, and fastening bolts. The front end of the rotating seat is connected to one end of the rotating arm via the damping pivot seat. The rear of the telescopic arm is inserted into the rotating arm, and fastening bolts are installed on the front side of the rotating arm. The angle of the rotating arm is adjusted according to the marking angle requirements, and the length of the telescopic arm in the rotating arm is adjusted according to the position of the working area. Then, the position of the telescopic arm is fixed by rotating the fastening bolts. This allows the equipment to adjust its effective working distance according to the working environment, improving the practicality of the device.

[0010] Preferably, the device also includes a U-shaped frame, a damping bearing, a scribing turntable, and a laser scribing head. The front end of the telescopic arm is connected to the U-shaped frame via the damping bearing. The scribing turntable is mounted on the U-shaped frame, and the laser scribing head is mounted on the side of the scribing turntable. The damping bearing facilitates the smooth rotation and adjustment of the U-shaped frame, while the scribing turntable facilitates the linear adjustment of the scribing area of ​​the laser scribing head. This reduces the impact of the laser scribing head's own vibration on accuracy during the adjustment of the scribing head's working area, thus improving the practicality of the device.

[0011] Preferably, the grip rod itself has a certain bending angle; by having a certain bending angle, the grip rod is easier for the operator to hold, improving the comfort and practicality of the device.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the main body of the equipment is fixed on the motor cover by the fixing device, the working direction of the equipment is adjusted by the adjusting device, and the working distance of the equipment is adjusted by the telescopic device, so that the equipment can be directly fixed on the inner surface of the workpiece, reducing the time consumed by the handling and position adjustment of the workpiece and improving the practicality of the device.
