Description

Technical Field

[0001] This utility model relates to the field of fixing fixture technology, specifically a fixing fixture for irregularly shaped materials of wind turbine blades. Background Technology

[0002] To address the issue of large, irregularly shaped materials shifting from their standard positions during the placement of materials within the wind turbine blade structure, clamping fixtures are currently used to secure the skin, vacuum membrane, and mold.

[0003] Existing wind turbine blade fixing fixtures are generally connected to the mold frame, which is inconvenient to use. Secondly, the screws used for clamping are directly welded to the pressure head or fastened with bolts. When pressing the skin and vacuum membrane, a protective layer is also placed on the outside of the vacuum membrane to prevent friction between the vacuum membrane and the pressure plate, which would cause wear to the vacuum membrane. This method is not convenient and increases costs. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture for fixing irregularly shaped materials for wind turbine blades. It is easy to move and not limited to clamping in a fixed position. It is highly flexible. The vacuum membrane and skin can be quickly pressed into the corresponding position of the mold by means of a screw and a pressure plate. The smooth surface of the end of the screw is interlocked with the connecting sleeve of the pressure plate. At the same time, the pin bolt with a smooth end is limited by the annular groove at the end of the screw. When the pressure plate is pressed on the surface of the vacuum membrane, the pressure plate will not rotate. There is no need to put a protective layer at the fixing point. The convenience is greatly improved and the cost is reduced, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing fixture for irregularly shaped wind turbine blade materials, comprising a frame body and a locking assembly;

[0006] The main frame includes a main beam, uprights and crossbars. The two ends of the main beam are connected to the upper part of the uprights respectively. The lower part of the uprights and the side close to the main beam are connected to the crossbars. The lower surface of the crossbars and the end away from the corresponding upright is provided with an upright plate. The two sides of the lower surface of the crossbars are respectively provided with first reinforcing plates. The two first reinforcing plates on the lower surface of the same crossbar are respectively connected to the two sides of the corresponding upright plate. The upright plate has a through hole and a first internal threaded sleeve is provided at the through hole.

[0007] The locking assembly includes a screw and a pressure plate. The screw passes through a first internally threaded sleeve and is threadedly engaged with the first internally threaded sleeve. One end of the screw has a smooth surface and an annular groove. A connecting sleeve is provided at the outer end of the pressure plate. A plurality of second internally threaded sleeves are evenly arranged radially on the outer side of the connecting sleeve. The second internally threaded sleeves are engaged with a pin bolt. A limit rod is provided at the end of the pin bolt, and the limit rod is inserted into the annular groove of the screw.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a fixing fixture for irregularly shaped wind turbine blade materials, including a frame body and a locking component;

[0021] The main frame includes a main beam 1, uprights 2 and crossbars 3. The two ends of the main beam 1 are connected to the upper part of the uprights 2 respectively. The lower part of the uprights 2 and the side close to the main beam 1 are connected to the crossbars 3. The connection between the uprights 2 and the main beam 1 and the crossbars 3 are provided with second reinforcing plates 14 to ensure the strength and stability of the overall structure of the main frame. The lower surface of the crossbars 3 and the end away from the corresponding upright is provided with a vertical plate 4. The two sides of the lower surface of the crossbars 3 are provided with first reinforcing plates 5 respectively. The two first reinforcing plates 5 on the lower surface of the same crossbars 3 are connected to the two sides of the corresponding vertical plate 4 respectively. The vertical plate 4 has a through hole and a first internal threaded sleeve 6 is provided at the through hole. The top of the main beam 1 is provided with a lifting handle 13 to facilitate lifting of the whole and to facilitate fine adjustment of the tooling position during fixing.

[0022] The locking assembly includes a screw 7 and a pressure plate 8. The screw 7 passes through a first internal threaded sleeve 6 and is threadedly engaged with the first internal threaded sleeve 6. One end of the screw 7 has a smooth surface and an annular groove 9. A connecting sleeve 10 is provided at the outer end of the pressure plate 8. Several second internal threaded sleeves 11 are evenly arranged radially on the outer side of the connecting sleeve 10. The second internal threaded sleeves 11 are engaged with a pin bolt 12. A limiting rod 1201 is provided at the end of the pin bolt 12. The limiting rod 1201 is inserted into the annular groove 9 of the screw 7. A rotating handle 15 is provided at the end of the screw 7 away from the annular groove 9 to facilitate the rotation of the screw 7.

[0023] Assembly method and operating principle: Uprights 2 are welded to both ends of the main beam 1 with the lifting handle 13. A crossbar 3 is welded to the inner side of the bottom of the uprights 2. An upright plate 4 is welded to the inner side of the lower surface of the crossbar 3. The two sides of the upright plate 4 and the two sides of the crossbar 3 are welded to the first reinforcing plate 5. Then, the first internally threaded sleeve 6 is installed on the inner surface of the upright plate 4 using bolts. Next, the screw 7 is passed through the corresponding first internally threaded sleeve 6. Then, the connecting sleeve 10 of the pressure plate 8 is inserted into the end of the screw 7 away from the rotating handle 15. Simultaneously, the pin bolt 12 is engaged with the second internally threaded sleeve 11, and the smooth part at the end of the pin bolt 12 is inserted into the annular groove 9 at the end of the screw 7, thereby achieving a rotatable connection between the screw 7 and the pressure plate 8. In use, the irregularly shaped material skin is placed on the surface of the semi-shell wind turbine blade mold. Then, a vacuum membrane is laid on the outside of the skin. Next, the frame body is placed on the side protrusion of the mold shell. Then, the screw 7 is rotated to press the pressure plate 8 against the outer surface of the vacuum membrane, thus pressing the vacuum membrane against the skin and the side protrusion of the mold. Figure 4 As shown, this design prevents slippage and ensures a tight connection between the vacuum membrane and the skin and the mold. This invention features a simple and reasonable structure, is easy to move, and is not limited to fixed clamping positions, offering high flexibility. The screw 7 and pressure plate 8 quickly press the vacuum membrane and skin onto the corresponding positions on the mold. The smooth surface of the screw 7's end interlocks with the connecting sleeve 10 of the pressure plate 8. Simultaneously, the pin bolt 12 with a smooth end engages with the annular groove 9 at the end of the screw 7 for limiting the movement. When the pressure plate 8 presses against the surface of the vacuum membrane, it will not rotate, eliminating the need for a protective layer at the fixing point. This significantly improves convenience and reduces cost. Furthermore, the first reinforcing plate 5 greatly enhances the connection strength and stability between the upright plate 4 and the crossbar 3, ensuring no deformation during clamping and preventing displacement of the skin during fixing.
