[0022] As Figure 1 - Figure 2 shown, an internal diagonal beam tooling for a wind turbine nacelle includes a first cross bar 1 and a second cross bar 2 arranged crosswise. A number of machining groove blocks 3 are arranged on the first cross bar 1 and the second cross bar 2; a support cross bar 4 is lapped at the intersection between the first cross bar 1 and the second cross bar 2; concave reference grooves located on the same horizontal plane are respectively arranged on the support cross bar 4 and the machining groove blocks 3; a round pin 5 and a threaded pin 6 that can cooperate with the machining holes on the diagonal beam are arranged on the machining groove blocks 3. The round pin 5 is in plug-in fit with the machining groove block 3, the end of the threaded pin 6 is in threaded connection with the machining groove block 3, and the top of the threaded pin 6 can press down on the diagonal beam.

[0023] Specifically, the internal diagonal beam tooling for a wind turbine nacelle consists of three parts, namely: an "X"-shaped machining base composed of the first cross bar 1 and the second cross bar 2, the threaded pin 6, and the round pin 5. The machining groove blocks 3 and the support cross bar 4 on the first cross bar 1 and the second cross bar 2 unify the assembly reference surface of the diagonal beam through the concave reference grooves and prevent the diagonal beam from falling; the round pin 5 and the threaded pin 6 position and fix each part on the diagonal beam through the pre-machined machining holes on the diagonal beam to the "X"-shaped machining base, so that when welding and machining the diagonal beam, each part of the diagonal beam can be accurately positioned and it is ensured that the diagonal beam will not shift when assembled and locked.

[0024] Furthermore, for the convenience of operation by operators, as Figure 1 shown, heightening legs 7 are arranged on the bottom sides of the first cross bar 1 and the second cross bar 2, and the height of the heightening legs 7 is 60 cm to 150 cm, which is suitable for operators to stand and work. At the same time, to increase the stability of the connection between the heightening legs 7 and the first cross bar 1 and the second cross bar 2, reinforcing rib plates 8 are arranged between the heightening legs 7 and the first cross bar 1 and the second cross bar 2.

[0025] Furthermore, to enhance the stability between the first crossbar 1 and the second crossbar 2, a reinforcing crossbar 9 is provided between the first crossbar 1 and the second crossbar 2.

[0026] In this technical solution, to increase the service life and structural strength of the diagonal beam tooling inside the wind turbine nacelle, the cross-sections of the first crossbar 1, the second crossbar 2, the heightening support leg 7, and the reinforcing crossbar 9 are square, and between the first crossbar 1 and the second crossbar 2, between the first crossbar 1 and the heightening support leg 7, between the second crossbar 2 and the heightening support leg 7, between the reinforcing crossbar 9 and the first crossbar 1, and between the reinforcing crossbar 9 and the second crossbar 2 are fixed by welding. Embodiment 2

[0027] Based on Embodiment 1, the machining groove block 3 can be slidably connected to the first crossbar 1 and the second crossbar 2 through linear guides. The linear guides are composed of rails and sliders, and the sliders can be fixed at any position on the rails through fasteners such as bolts; preferably, rails are provided on both the first crossbar 1 and the second crossbar 2, and the machining groove block 3 is installed on the sliders. Furthermore, by adjusting the position of the machining groove block 3 on the first crossbar 1 and the second crossbar 2, the diagonal beam tooling inside the wind turbine nacelle in this technical solution can be applicable to diagonal beams of different lengths.

[0028] Furthermore, to facilitate the diagonal beam tooling inside the wind turbine nacelle to be applicable to diagonal beams of different angles, on the premise of removing the reinforcing crossbar 9, the first crossbar 1 and the second crossbar 2 can be hinged.

[0029] Working principle: The diagonal beam tooling inside the wind turbine nacelle consists of three parts, namely: an "X"-shaped machining base composed of the first crossbar 1 and the second crossbar 2, a threaded pin 6, and a round pin 5. The machining groove blocks 3 and the support crossbars 4 on the first crossbar 1 and the second crossbar 2 unify the assembly reference surface of the diagonal beam through the concave reference grooves, and at the same time can also prevent the diagonal beam from falling, and can initially position the position of the diagonal beam; subsequently, the round pin 5 and the threaded pin 6 can position and fix each part on the diagonal beam to the "X"-shaped machining base through the pre-machined machining holes on the diagonal beam. The positioning is accurate and can ensure that the diagonal beam will not shift when assembled and locked. The entire diagonal beam tooling inside the wind turbine nacelle has a simple structure and convenient operation, and can quickly and accurately position the position of the diagonal beam.

[0030] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
