[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A drilling machine for stator flange processing includes a base frame 1, a support frame 2 fixedly connected to the upper right side of the base frame 1, a drill 3 provided at the left end of the support frame 2, a support shaft 4 installed inside the base frame 1 via bearings, a support plate 5 fixedly connected to the upper end of the support shaft 4, the support plate 5 being rotatably connected to the base frame 1, the upper end of the support plate 5 contacting the flange body 6, and a positioning block 7 fixedly connected to the upper end of the support plate 5, the positioning block 7 contacting the flange body 6;

[0023] A fixing plate 8 is fixedly connected to the upper end of the support plate 5. A screw cylinder 9 is installed inside the fixing plate 8 through a bearing. A screw rod 10 is connected to the inner wall of the screw cylinder 9 through a thread. A clamping plate 11 is fixedly connected to the end face of the screw rod 10 near the flange body 6. The clamping plate 11 is in contact with the flange body 6 and the support plate 5.

[0024] Please see Figure 1 , Figure 2 , Figure 3 There are four positioning blocks 7, which are arranged in a ring array on the support plate 5. The flange body 6 can be positioned by the positioning blocks 7. The upper end of the clamping plate 11 is fixedly connected to the guide plate 12, which is slidably connected to the fixing plate 8. The clamping plate 11 can be guided by the guide plate 12.

[0025] Please see Figure 1 , Figure 2 , Figure 4A positioning mechanism 13 is provided on both the support shaft 4 and the base frame 1. The positioning mechanism 13 includes a locking hole 131. The lower end of the base frame 1 has a locking hole 131. The end plate of the support shaft 4 is slidably connected to a locking rod 132. The locking rod 132 is slidably connected to the locking hole 131. The lower end of the locking rod 132 is fixedly connected to an end ring 133, which is made of rubber. A spring 134 is provided on the outside of the locking rod 132. Through the setting of the locking hole 131, locking rod 132 and other structures, the support shaft 4 can be inserted, thereby limiting the support plate 5, so that the flange body 6 is stable after the position is adjusted.

[0026] Please see Figure 1 , Figure 2 , Figure 4 Multiple locking holes 131 are provided, and the multiple locking holes 131 are arranged in a circular array on the base frame 1. The locking holes 131 are provided to facilitate the insertion and use of locking rod 132. One end of spring 134 is welded to the end plate of support shaft 4, and the other end of spring 134 is welded to the connecting plate of locking rod 132. The locking rod 132 can be connected and used through the setting of spring 134.

[0027] The specific implementation process of this utility model is as follows: In use, by placing the flange body 6 on the upper end of the support plate 5, the positioning block 7 is embedded in the inner wall of the flange body 6 to pre-position the flange body 6. Then, the screw cylinder 9 is pushed to rotate. Under the threaded connection, the screw 10 can be driven to move, thereby driving the clamping plate 11 to move. The clamping plate 11 drives the guide plate 12 to slide along the inner wall of the fixing plate 8 to ensure the stability of the movement of the clamping plate 11. Finally, the clamping plate 11 contacts the flange body 6 to clamp and fix the flange body 6.

[0028] By pulling the end ring 133 downward, the locking rod 132 is moved, allowing it to slide stably along the inner wall of the end plate of the support shaft 4. The spring 134 deforms, eventually causing the locking rod 132 to disengage from the locking hole 131. This allows the support plate 5 to rotate, which in turn rotates the support shaft 4 and the flange body 6, adjusting its position for subsequent drilling. As the support shaft 4 rotates, the locking rod 132 moves along the surface of the base frame 1. When the locking rod 132 slides into the next locking hole 131, the spring 134 returns to its original shape, pulling the locking rod 132 into the locking hole 131 to limit the support shaft 4, thereby positioning the flange body 6 after adjustment.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
