DETAILED DESCRIPTION

[0024] Please refer to Figures 1-4A jig for machining a wind turbine generator support casting includes a support block 1. Stabilizing columns 2 are fixedly connected to the four corners of the top of the support block 1. A support plate 3 is fixedly connected between the tops of the four stabilizing columns 2. Two sliding grooves are formed at the top of the support plate 3. Sliding blocks 4 are slidably connected inside each of the two sliding grooves. Clamping plates 5 are fixedly connected to the tops of each of the two sliding blocks 4. Transmission blocks 20 are fixedly connected to the bottoms of each of the two sliding blocks 4. Transmission racks 6 are fixedly connected to the ends of the two transmission blocks 20 that are close to each other. A rotating rod 7 is rotatably connected to the bottom of the support plate 3. A rotating gear 8 is fixedly connected to the outer wall of the rotating rod 7. The two ends of the rotating gear 8 mesh with the two transmission racks 6 respectively. An adjustment groove is formed at the top of the support block 1. A motor groove is formed at one end of the adjustment groove. A first motor 9 is fixedly connected to one end of the motor groove. A rotating screw 10 is fixedly connected to the output end of the first motor 9. A rotating sleeve 11 is screwed onto the outer wall of the rotating screw 10. The top of the rotating sleeve 11 is fixedly connected to the bottom end of one of the transmission blocks 20.

[0025] By placing the casting on the top of the support plate 3, and energizing the first motor 9, the output of the first motor 9 will drive the rotating screw 10 to rotate. The rotating screw 10 will drive the rotating sleeve 11 to move through the threaded engagement, and drive one of the transmission blocks 20 to move. The transmission block 20 will drive the rotating gear 8 to rotate through the transmission rack 6, and drive the other transmission rack 6 to move under the tooth meshing. This will drive the two transmission blocks 20 to move in opposite directions, and drive the two clamping plates 5 to move closer to each other through the sliding block 4, thereby completing the positioning and clamping of the casting. This avoids the need to adjust the position when processing the generator support casting later, and improves the efficiency of processing the generator support casting.

[0026] It should also be noted that limit grooves are provided at both ends of the two sliding grooves, and limit sliders 12 are slidably connected inside the two limit grooves. One end of each limit slider 12 is fixedly connected to both ends of the sliding block 4. During the movement of the sliding block 4, it will move inside the limit groove through the limit sliders 12, thereby further improving the stability of the movement of the sliding block 4.

[0027] Two limiting plates 13 are fixedly connected to the top of the support plate 3. Two limiting through holes are opened at one end of each of the two limiting through holes. Limiting rods 14 are slidably connected inside the two limiting through holes. The inner ends of the two limiting rods 14 are fixedly connected to the outer end face of the clamping plate 5. Limiting blocks 15 are fixedly connected to the outer ends of the multiple limiting rods 14.

[0028] When the clamping plate 5 moves, it will drive the limiting rod 14 to move inside the limiting through hole, thereby improving the synchronicity of the movement of the two clamping plates 5 and further improving the stability of the movement of the clamping plate 5.

[0029] In addition, support feet 16 are fixedly connected to the four corners of the bottom of the support block 1, providing support for the entire device and increasing its height. Mounting members 17 are fixedly connected to both ends of the support block 1. Each mounting member 17 has a mounting through hole at its top, and multiple mounting through holes are fitted with fixing rivets 18, facilitating easier fixing of the entire device. Anti-slip plates 19 are fixedly connected to the inner end faces of the two clamping plates 5, providing anti-slip properties when the clamping plates 5 contact the generator support casting, thus improving clamping efficiency.

[0030] In summary, when using this jig for machining wind turbine generator support castings, the casting is first placed on the top of the support plate 3. With the first motor 9 energized, its output drives the rotating screw 10 to rotate. The rotating screw 10, through its threaded engagement, drives the rotating sleeve 11 to move, which in turn moves one of the transmission blocks 20. The transmission block 20, through the transmission rack 6, drives the rotating gear 8 to rotate, and through the meshing of the rack, drives another transmission rack 6 to move. This causes the two transmission blocks 20 to move in opposite directions, and the sliding block 4 moves the two clamping plates 5 closer together, thus completing the positioning and clamping of the casting. During the movement of the sliding block 4, the limiting slider 12 moves within the limiting groove, further improving the stability of the sliding block 4's movement. When the clamping plates 5 move, the limiting rod 14 moves within the limiting through hole, further improving the synchronicity of the movement of the two clamping plates 5 and enhancing their stability.
