[0018] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0019] The following is combined with Figure 1-2 The utility model is described in further detail.

[0020] The utility model embodiment discloses a guide cover assembly inspection tooling platform.

[0021] Reference Figure 1 and Figure 2 A shroud assembly inspection tooling platform includes a base 1 and an upper frame 2. The upper frame 2 and the base 1 are fixedly connected by a connecting rod 3. A lower frame 4 is arranged on the outer side of the base 1. A lower positioning plate 5 is arranged on the lower frame 4. A mounting seat 6 is arranged on the upper frame 2. An upper positioning plate 7 is arranged on the mounting seat 6. The upper positioning plate 7 is used to align with the upper embedded iron plate on the top of the shroud, and the lower positioning plate 5 is used to align with the lower embedded iron plate on the bottom of the shroud. If the shroud can be installed and fixed with all the bolt holes smoothly, it can be determined that the embedded iron plate is positioned properly. After the shroud is installed, it is in the final assembly state, and the shroud shape, blade holes and other dimensions can be inspected, which greatly improves the efficiency of the installation and inspection operations and also provides a guarantee for the installation of the operator.

[0022] The fairing product used in the utility model is composed of three sub-assembly pieces, which are fixed and locked in sequence to form a fairing. The inspection tooling platform is located inside the fairing after the three sub-assembly pieces are installed. Three iron plates are embedded on the top of each sub-assembly piece, two are embedded on the rear end vertical surface, and one is embedded on the front end curved surface. Each embedded iron plate is preset with four M16 mounting holes. The process requires that the spacing tolerance between the nine iron plates is plus or minus 1mm.

[0023] The main frame of the utility model is welded with 80 square tubes, which effectively ensures the overall strength of the platform. The base 1 is a base 1 with a hexagonal cross section formed by welding multiple square tubes, and a support leg is arranged on the base 1 to support the platform on the ground.

[0024] The lower frame 4 is fixed to the outside of the base 1 through a plurality of square tubes. The cross section of the lower frame 4 is hexagonal and the lower frame 4 is also welded and formed by square tubes. A gap is formed between the lower frame 4 and the base 1 through the square tubes, so that the staff can enter the base 1 from the outside of the lower frame 4 and it is convenient to inspect the deflector on the lower frame 4 at a later stage.

[0025] The lower positioning plate 5 is fixed to the lower frame 4 by a fixing rod 10, and a T-shape is formed between the lower positioning plate 5 and the fixing rod 10. The fixing rod 10 is a short square tube. When installing the fixing rod 10, its position and the distance extended from the lower frame 4 should meet the internal size requirements of the air deflector, so that the bolt holes on the air deflector with the correct size can be aligned with the bolt holes on the lower positioning plate 5 after assembly, thereby ensuring the inspection results.

[0026] The connecting rod 3 is welded to the base 1 by a square tube, and the upper frame 2 is welded to the top of the connecting rod 3 by a square tube. The cross section of the upper frame 2 is a hexagon.

[0027] The mounting seat 6 is formed by welding a plurality of square tubes and fixedly arranged on the top of the upper frame 2. The mounting seat 6 is used to form a fixed platform for the upper positioning plate 7 so that the upper positioning plate 7 can contact the corresponding part of the air deflector. The position of the upper positioning plate 7 installed on the mounting seat 6 should meet the corresponding requirements so that it can be aligned with the upper embedded iron plate in the correct position.

[0028] Bolt holes are provided on the upper positioning plate 7 and the lower positioning plate 5. The bolt holes of the upper positioning plate 7 are aligned with the bolt holes of the upper embedded iron plate, and the bolt holes of the lower positioning plate 5 are aligned with the bolt holes of the lower embedded iron plate. The above embedded iron plates are all the correct size after correct installation, so that the upper positioning plate 7 and the lower positioning plate 5 can be aligned. If the installation position on the air deflector is wrong or the hole position is wrong, they will not be aligned. The upper positioning plate 7 and the lower positioning plate 5 are both processed by CNC. Due to the use of CNC processing, the accuracy of the holes of the upper positioning plate 7 and the lower positioning plate 5 can be effectively guaranteed, thereby ensuring the subsequent inspection results.

[0029] Wherein, each of the upper positioning plate 7 and the lower positioning plate 5 is provided with four bolt holes.

[0030] The upper frame 2 and the lower frame 4 are both hexagonal in design, so that the platform can inspect each packaged piece of the guide cover at the same time, thereby improving the inspection efficiency.

[0031] Among them, three mounting seats 6 are arranged at intervals along the circumference of the upper frame 2, and the upper positioning plates 7 on the three mounting seats 6 are respectively aligned with the positions of the upper embedded iron plates corresponding to the air deflector.

[0032] Three positioning assemblies are arranged at intervals along the circumference of the lower frame 4, and each positioning assembly is provided with two lower positioning plates 5. The lower positioning plates 5 of the same group of positioning assemblies are arranged at intervals between two adjacent lower positioning plates 5 of the same group of positioning assemblies to align with the lower embedded iron plate of the same air deflector. The position and number of the arrangement can correspond to the inspection position and number of the actual air deflector.

[0033] An operating platform 8 is provided between the lower frame 4 and the upper frame 2, a ladder 9 is provided between the operating platform 8 and the base 1, and the operating platform 8 is fixedly connected to the connecting rod 3. In order to facilitate the staff to inspect the upper positioning plate 7 on the upper frame 2, the operating platform 8 is built. The operating platform 8 is made of a steel plate, and the steel plate is grooved at the corresponding position of the connecting rod 3. The steel plate is fixed to the connecting rod 3 by welding. The operating platform 8 can take into account the positioning and fixing of the connecting rod 3, prevent the connecting rod 3 from tilting and bending, and ensure the inspection result. The cross section of the operating platform 8 is hexagonal, and a ladder 9 opening is provided on the operating platform 8. The top of the ladder 9 is set at the ladder 9 opening. The position of the ladder 9 opening is staggered with the position of the mounting seat 6, which is convenient for the staff to inspect the upper positioning plate 7.

[0034] If the three sub-assembly pieces of the air deflector can be installed smoothly and can be aligned with the bolt holes of the upper positioning plate 7 and the lower positioning plate 5 at the corresponding positions, it can be determined that the production size of the air deflector is correct and the embedded iron plate positioning is qualified. In addition, the air deflector can be installed through the platform of the utility model, and it is also the actual final assembly state. Therefore, the shape, blade holes and other dimensions can be inspected, which greatly improves the efficiency of the installation inspection operation and also provides protection for the installation of the operator.
