[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0044] Embodiment one: please refer to Figures 1-4 The present application provides a technical solution: a wind power blade mold clamping mechanism with adjustable range, comprising: a blade mold body 1, which is fixedly installed on the top of a positioning clamping support 2 through bolts, and an outer positioning cavity 3 is further fixed on the bottom side wall of the blade mold body 1;

[0045] In the technical solution, the positioning and clamping support 2 and the bolt are used to realize the positioning of the blade mold body 1. Due to the size requirement of the production and manufacturing of the wind power blade, the overall large constant is constant, so the length, size and size of the blade mold body 1 are also constant. The positioning and clamping support 2 is provided to realize the positioning and assembly of the blade mold body 1, which is convenient for the butt joint assembly of the formed wind power blade in the later period.

[0046] Further comprising: the auxiliary positioning block 4 is embedded on the inner side wall of the blade mold body 1 at equal intervals, and the outer positioning cavity 3 below the auxiliary positioning block 4 is fixed with the mounting bracket 5 and the positioning bracket 7, the telescopic rod 6 is rotatably connected in the mounting bracket 5, the output shaft end of the telescopic rod 6 is fixed with the center of the back surface of the auxiliary positioning block 4, and the positioning bracket 7 is penetrated through the back surface of the auxiliary positioning block 4; the elastic element 8 is arranged in the telescopic rod 6, and the airflow vibrator 601 is arranged on the outer side wall of the telescopic rod 6; the outer positioning cavity 3 is also provided with an airflow conveying component, which drives the auxiliary positioning block 4 to shake and exhaust; the inner side of the auxiliary positioning block 4 and the inner side of the blade mold body 1 are both provided with curved surface structure, and the curved surface structures of the two are coplanar; the auxiliary positioning block 4 is coaxially fixed with the telescopic rod 6, and the telescopic rod 6 is connected with the mounting bracket 5 through the middle shaft and the bearing to form a relative rotation structure; the mounting bracket 5 is provided in the shape of "U", and the middle part of the "U" shape of the mounting bracket 5 is parallel to the bottom of the telescopic rod 6 with a certain distance, and the two are magnetically attracted and positioned.

[0047] In the above technical solution, the auxiliary positioning block 4 belongs to the demolding mechanism used in the mold, and the blade mold body 1 forms a complete wind power blade manufacturing mold. Since the auxiliary positioning block 4 needs to realize subsequent demolding, it needs to be clamped and positioned. The clamping and positioning mechanism is used to realize the installation and limiting of the auxiliary positioning block 4, which prevents the wind power blade from being prepared and formed due to loosening during use. The clamping mechanism includes the telescopic rod 6, the positioning bracket 7 and other auxiliary positioning components. The telescopic rod 6 and the elastic element 8 inside it are used to realize the reverse pushing and limiting of the auxiliary positioning block 4. Under the penetration of the positioning bracket 7 and the auxiliary positioning block 4, the auxiliary positioning block 4 is stably positioned and will not loosen. At the same time, the airflow conveying component can be used. Under the action of airflow, the telescopic rod 6 is stretched and shaken to release the limiting state of the auxiliary positioning block 4, so that it can be shaken in different amplitude ranges due to the change of wind power airflow. The telescopic rod 6 and the mounting bracket 5 are relatively turned over due to vibration, so that the auxiliary positioning block 4 is separated from the formed wind power blade, and the pressurized airflow is introduced at the position where the two are separated to realize the rapid separation of the wind power blade and the mold.

[0048] In the technical solution, the positioning support 7 and the auxiliary positioning block 4 are in a telescopic and movable mounting, and the end of the positioning support 7 on the curved side of the auxiliary positioning block 4 is in a rounded table structure, and the end of the positioning support 7 is connected with the curved side wall of the auxiliary positioning block 4. By using the technical solution, when the auxiliary positioning block 4 is clamped by the clamping mechanism, the auxiliary positioning block 4 is directly limited by the positioning support 7, and when the auxiliary positioning block 4 is moved downward due to the contraction of the telescopic rod 6, the auxiliary positioning block 4 is in a direct limiting state with the positioning support 7, and the shaking of the auxiliary positioning block 4 is not affected, and the shaking is caused by the expansion and contraction of the telescopic rod 6 and the relative turning action between the telescopic rod 6 and the mounting support 5.

[0049] Meanwhile, the clamping method of the wind power blade mold clamping mechanism is also disclosed in the embodiment, and the specific method is as follows:

[0050] S1: First, the blade mold body 1 is supported by the positioning and clamping support 2, the positioning and clamping support 2 is in a pipeline truss structure, and the blade mold body 1 is clamped and positioned by bolts;

[0051] S2: The auxiliary positioning block 4 is arranged on the blade mold body 1 in an equal-interval embedded manner, and the auxiliary positioning block 4 is positioned by the mounting support 5, the telescopic rod 6 and the positioning support 7, so that the auxiliary positioning block 4 is prevented from loosening during the molding and manufacturing of the wind power blade;

[0053] Embodiment two: based on the embodiment one, the application further discloses a method and a technical solution for how the clamping mechanism realizes the rapid separation of the mold and the wind power blade at the position of the auxiliary positioning block 4, and the specific content is as follows:

[0054] The telescopic rod 6 is hollow, the inside of the telescopic rod 6 and the inside of the outside positioning cavity 3 are communicated through the hollow hole, and there is a difference between the metal material and the thermal expansion coefficient of the inside and the outside of the elastic element 8 in the telescopic rod 6; in the technical scheme, the elastic element 8 with material difference is arranged first, because of the difference in the thermal expansion coefficient of the metal, when the airflow conveying component introduces the airflow with pressure and high heat into the inside of the outside positioning cavity 3, the airflow can directly cause the elastic element 8 to deform and shrink, so that the telescopic rod 6 shrinks to drive the auxiliary positioning block 4 to move and change position, and at the same time, in order to improve the heat shrinkage efficiency of the elastic element 8, a memory metal with high thermal sensitivity can be used; at the same time, the gas flow rate difference introduced by the airflow conveying component can achieve the shaking of the telescopic rod 6 under the impact of airflow with different speeds due to the elastic reaction force of the elastic element 8.

[0055] The airflow conveying component comprises a guide flow threaded pipe 12 which is movably installed through the outer wall of the positioning cavity 3; at the same time, the inside of the outside positioning cavity 3 is fixedly provided with a guide sliding rod 9 which is coaxial along the direction thereof, the outside of the guide sliding rod 9 is slidably provided with a cover bracket 10, the bottom of the cover bracket 10 is fixedly provided with a multi-way electromagnetic valve 11, the multi-way electromagnetic valve 11 is connected with the guide flow threaded pipe 12, the left and right sides of the multi-way electromagnetic valve 11 are provided with exhaust holes, the direction of the exhaust holes is the same as the direction of the guide sliding rod 9; the outside of the guide sliding rod 9 is provided in a rectangular shape, the rectangular outer wall of the guide sliding rod 9 is slidably connected with the cover bracket 10 in a radial clamping and axial fitting manner, and the two are weakly magnetically attracted and positioned; the cover bracket 10 is movably provided with an air bag ring 13, a film is arranged between the air bag ring 13 and the outside of the cover bracket 10, the connection between the air bag ring 13 and the cover bracket 10 is provided in an annular structure, the cover bracket 10 is provided with an elastic air bag 14, the air bag ring 13, the elastic air bag 14, the cover bracket 10, the multi-way electromagnetic valve 11 and the guide flow threaded pipe 12 are sequentially communicated; the elastic air bag 14 is provided in a strip shape, the two ends of the elastic air bag 14 are fixedly connected with the inside of the cover bracket 10 and the annular structure of the air bag ring 13 in a penetrating manner; the middle part of the cover bracket 10 and the middle part of the mounting bracket 5 are provided with photoelectric sensors 15, the two photoelectric sensors 15 are correspondingly arranged, and the middle part of the cover bracket 10 is further provided with an exhaust port;

[0056] In the above technical solution, in order to improve the stability and efficiency of the air flow introduced by the air flow conveying component, the auxiliary positioning block 4 to be precisely positioned by the air flow can be used according to the use requirement. By using the technical solution, first, the computer numerical control equipment outside is used to control the exhaust of the exhaust hole on the multi-way electromagnetic valve 11, and under the action of the exhaust force of the gas, the cover body support 10 moves axially along the guide sliding rod 9, changes the position of the cover body support 10, and at the same time, the signal transmission of the photoelectric sensor 15 is used. When the photoelectric sensor 15 in the middle of the cover body support 10 is coaxial with the photoelectric sensor 15 in the middle of the installation support 5 corresponding to the auxiliary positioning block 4, the photoelectric sensor 15 receives the photoelectric signal and transmits it to the computer numerical control equipment outside, which facilitates the manual control of the positioning state of the cover body support 10. Then, the multi-way electromagnetic valve 11 is used again to make the gas pass through the flow guide threaded pipe 12 and enter the cover body support 10 and the air bag ring 13, so that the air bag ring 13 moves and expands, and the corresponding auxiliary positioning block 4 and the clamping mechanism on the back of the auxiliary positioning block 4 are wrapped by the air bag ring 13 and the film connected thereto. The air flow discharged from the exhaust port in the middle of the cover body support 10 is directly introduced into the auxiliary positioning block 4, which reduces the air flow escape and makes the structure on the back of the auxiliary positioning block 4 receive the air flow impact more stably, realizes the contraction of the telescopic rod 6 and the positioning movement and shaking of the auxiliary positioning block 4, and at the same time, the air flow vibrator 601 arranged on the outside of the auxiliary positioning block 4 makes the shaking frequency and range of the auxiliary positioning block 4 directly controlled by the air flow, realizes the demolding of the wind power blade, and at the same time, most of the air flow is introduced into the contact surface between the mold and the wind power blade through the gap between the auxiliary positioning blocks 4, which improves the demolding efficiency of the wind power blade.
