However, it should not be construed as a limitation on the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a positioning tooling for the processing of a shearer planet carrier, including a processing platform 1, an adjusting turntable 12, and a positioning wheel 13. The bottom of the processing platform 1 is fixedly installed with installation support legs 2.

[0021] Further, the number of installation cross plates 3 is two groups. The adjacent side walls of the two groups of installation cross plates 3 are connected by a connecting cross plate 10. The bottom of the connecting cross plate 10 is fixed with a driving motor 11. The rotating shaft of the driving motor 11 extends to the top of the connecting cross plate 10 and is fixedly installed with an adjusting turntable 12.

[0022] Still further, the bottom of the processing platform 1 is fixedly installed with an installation vertical plate 5. One side of the installation vertical plate 5 is fixedly installed with a telescopic spring 6. One side of the telescopic spring 6 is fixedly installed with a movable block 7. One side of the movable block 7 is fixedly installed with a guide rod 8. One end of the guide rod 8 extends to one side of the installation vertical plate 5 and is fixedly installed with a limiting block. The guide rod 8 is slidably installed with the installation vertical plate 5. A rotating rod 9 is rotatably installed inside the movable block 7. The outer wall of the rotating rod 9 is fixedly installed with a positioning wheel 13. This setting can, during the process of positioning the shearer planet carrier body 4, position the shearer planet carrier body 4 through a three-point positioning method. This positioning method is not only convenient for workers to operate, but also more accurate than the traditional two-point positioning method, improving the positioning accuracy of the shearer planet carrier body 4, facilitating subsequent processing of the shearer planet carrier body 4. At the same time, such a positioning method can position shearer planet carrier bodies 4 of different sizes, increasing the applicable range of the device and improving the practicality of the device.
