The structures and principles thereof are known to those skilled in the art through technical manuals or conventional experimental methods. The problem solved by the present invention is that it is easy to cause the position of the casting to shake, thereby causing the position of the drilling hole of the casting to shift, thereby reducing the efficiency of the drilling of the casting and making it difficult to achieve accurate drilling processing. The present invention combines the above-mentioned parts with each other, and limits the sliding of the upper and lower limit rings 1. The dynamically connected rotating sliding mechanism 21 combined with the positioning and clamping mechanism 22 fixedly distributed on its inner wall can realize multi-angle positioning and clamping of precision castings through the driving structure 23, thereby improving the flexibility and stability of processing and ensuring the accuracy of the processing position. The precision casting support mechanism 3 arranged in the middle of the bottom of the fixed ring 1 is convenient for automatically adjusting the support according to the precision castings of different heights. The drilling mechanism 4 arranged above the fixed ring 1 adopts an independent motor and drill bit to realize precise control of drilling, and can also dynamically lift and adjust the depth of drilling at the same time, thereby further improving the processing accuracy.

[0028] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.

Any figure mark in the claims should not be regarded as limiting the claims involved.

[0029] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
