[0008] To further optimize the technical solution, the base is circular and a boss is provided on the edge of the upper end surface of the base.

[0009] To further optimize the technical solution, two bosses are provided, and the two bosses are stepped.

[0010] To further optimize the technical solution, the tightening mechanism includes a first tightening bolt and a second tightening bolt respectively arranged at both ends of the through hole groove, and the first tightening bolt and the second tightening bolt are arranged opposite to each other and are equipped with nuts.

[0011] To further optimize the technical solution, the first tightening bolt is located on the center line of the through hole groove, the second tightening bolt is located at the edge of the through hole groove, and the second tightening bolt is parallel to the first tightening bolt.

[0012] Due to the adoption of the above technical scheme, the technical progress achieved by the utility model is as follows.

[0013] The utility model provides a positioning device for machining a valve plate with a central axis passing through a column, which fixes the valve plate in the up and down direction by means of a clamping column, and prevents the valve plate from sliding left and right in the through-hole groove by means of a first clamping bolt and a second clamping bolt, thereby stably fixing the valve plate. The utility model has a simple structure and is easy to use, which is conducive to fixing the valve plate with a central axis passing through a column during machining, and can improve machining accuracy and machining efficiency.
