Problems solved by technology

However, the traditional auxiliary support structure generally requires manual adjustment, the adjustment process is time-consuming, and the posture of the support after adjustment is fixed, which is only suitable for rotating workpieces, not suitable for non-rotating parts such as blades

Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] see Figure 1 to Figure 7 .

[0059] The invention relates to a motion control method for a middle support device in the forming process of a large-scale wind power blade, and the control method adopts a control mode combining an upper computer and a lower computer. see figure 1 , 2 As shown, the middle support device includes a left support plate 1 , a right support plate 2 and a middle support plate 3 . The upper computer is an industrial computer, and its function is to obtain the motion track data of the support plate by running the support track calculation program, that is, the corresponding swing position of the support plate when the blade rotates to each moment. At the same time, the upper computer transmits the obtained data to the lower computer before the blade starts to rotate. The lower computer adopts Trio 209 multi-axis motion cont...

Abstract

The invention belongs to the technical field of machinery and in particular relates to a motion controlling method for a middle support device in a process of forming a large-scale wind turbine blade. Through the method, a left support plate, a right support plate and a middle support plate moves to corresponding positions along with a blade support section when the blade rotates at an angle of delta around a rotation center, so that the automatic control during forming of the blade is realized. The method comprises a method for controlling the left support plate and the right support plate and a method for controlling the middle support plate. The motion controlling method is a key technology for manufacturing large-scale wind turbine blade winding forming equipment and can be popularized in the process of forming non-rotational weak rigidity parts such as helicopter propeller blades and turn-milling machining centers to assist in motion control on support mechanisms.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a motion control method for a middle supporting device in the forming process of a large wind power blade. Background technique [0002] Composite materials can obtain superior comprehensive performance that cannot be compared with a single material through the synergistic effect of each component material in terms of performance. It is widely used in wind power blades because of its light weight, high strength, corrosion resistance, good fatigue resistance, and good shock resistance. At present, the composite molding process of fan blades is mainly divided into open mold molding and closed mold molding, but both molding processes have certain defects and cannot meet the needs of scientific research and modern rapid production, so a combination of laying and wrapping is proposed How the blade is formed. During blade laying and forming, the blade mandrel rotates ar...
