[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model.

[0019] Such as Figures 1-5As shown in the figure, the present utility model provides the following technical solutions to improve the machining quality of the holes on the upper and lower sides of the transmission housing of a wind power gearbox: A fixture for the transmission housing of a wind power gearbox, including a workbench 1, on the upper surface of the workbench 1, a plurality of strip-shaped mounting grooves 11 pointing to the center of the circle are provided along the circumferential direction. The cross-section of the mounting groove 11 is T-shaped, and a T-shaped block 8 is arranged in the mounting groove 11; a bottom plate 2, which is arranged on the upper side of the workbench 1. An adjustment groove 21 corresponding to the mounting groove 11 is provided on the bottom plate 2. A limiting column 3 is selectively installed in the adjustment groove 21. The space between the plurality of limiting columns 3 is used to place the transmission housing 4 of the wind power gearbox; a fixed seat 5, which is arranged in multiple numbers on the upper side of the bottom plate 2 and can slide and adjust along the adjustment groove 21. A pressing rod 7 is arranged at the upper end of the fixed seat 5. A pressing plate 6 is arranged between adjacent fixed seats 5. The pressing plate 6 can slide along the adjustment groove 21, which can quickly fix the transmission housing, thereby ensuring high positional accuracy of the machined holes.

[0020] In this embodiment, as Figure 5 shown, a strip-shaped slot 61 is provided on the pressing plate 6. A screw rod 9 is inserted into the slot 61. The screw rod 9 passes through the adjustment groove 21 and is connected to the corresponding T-shaped block 8, which is convenient for adjustment and easy to install.

[0021] In this embodiment, as Figure 4 shown, two mounting holes 51 are symmetrically arranged at the lower end of the fixed seat 5. The fixed seat 5 is connected to the corresponding T-shaped block 8 through fasteners passing through the mounting holes 51, with a simple structure and easy installation.

[0022] In this embodiment, as Figure 1 shown, an external thread is provided at the lower end of the limiting column 3. The limiting column 3 is connected to the corresponding T-shaped block 8 through the external thread, with a simple structure and easy installation.
