Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation blade processing, in particular to a wind power generation blade curved surface positioning tool. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has been used by people for a long time;

[0003] Existing wind turbines mainly generate electricity by driving the generator to rotate through the action of wind force on the surface of the blades. During the production and processing of wind turbine blades, positioning tools are needed to position them. However, most of the positioning tools actually used are simple clamps. When clamping the blades, the surface of the blades is curved, so the clamping fit is poor. As a result, the blades are prone to shaking or shifting during the processing, which affects the processing accuracy. Therefore, we propose a curved surface positioning tool for wind turbine blades.

[0006] By adopting the above technical solution, the blade is placed between the two frames, and then the upper frame is adjusted to descend and the lower frame is adjusted to close by the adjustment plate, so as to achieve preliminary positioning of the blade, and then the servo motor is started to drive the screw to rotate, thereby driving the lifting column to rise and fall, so that multiple clamping blocks can be clamped at different positions of the outer wall of the blade, so that the blade can be clamped and positioned by the upper and lower clamping blocks, and the fit during clamping and positioning ensures the stability of the positioning, thereby ensuring the accuracy of the blade processing.

[0007] As a preferred embodiment of the utility model, a groove is formed at the outer end of the lifting column, the insertion rod is inserted into the groove, a pressure switch is fixed to the end surface of the inner cavity of the groove, and the outer end of the pressure switch is fixedly connected to the inner end of the insertion rod.

[0008] By adopting the above technical solution, after the clamping block is pressed against the surface of the blade, the servo motor will be automatically turned off when the clamping pressure reaches a certain level, thereby ensuring that the clamping degree of each clamping block is the same, thereby further ensuring the clamping fit and further improving the clamping positioning stability.

[0009] As a preferred embodiment of the utility model, a slide groove is opened on the upper side of one side wall of the adjustment plate, a screw motor is fixed on the top of the inner cavity of the slide groove, a screw is fixedly connected to the outer end of the transmission shaft of the screw motor, the outer end of the screw is rotatably connected to the bottom of the inner cavity of the slide groove, the outer wall of the screw is covered with an adaptive screw slider, and the outer wall of the screw slider is fixedly connected to the side wall of the frame located on the upper side.

[0010] By adopting the above technical solution, the screw motor can drive the screw to rotate, thereby driving the screw slider to descend, thereby driving the upper frame to descend and the lower frame to close.

[0011] As a preferred embodiment of the present invention, plug boards are fixed on both sides of the top of the frame body at the lower side, and matching slots are provided on both sides of the rear end of the frame body at the upper side.

[0012] By adopting the above technical solution, the inserting plate can be inserted into the slot after the frame located on the upper side is lowered, thereby achieving high closing stability.

[0013] As a preferred embodiment of the present invention, the outer wall of the abutting block is sleeved with an adaptive rubber pad.

[0014] By adopting the above technical solution and providing the rubber pad, it is possible to avoid abrasion on the surface of the blade when the blade is clamped and positioned.

[0015] As a preferred embodiment of the present invention, mounting holes are provided at the four corners of the top of the base.

[0016] By adopting the above technical solution and setting the mounting holes, it is convenient to install and fix the entire device.
