[0017] The present utility model will be further described below in combination with the drawings.

[0018] As shown in Figure 1 and Figure 2 A blade casting positioning point position flatness detection tool, comprising a connecting plate 1 and a large support 9;

[0019] The connecting plate 1 is vertically fixedly installed on the right end of the large support 9, the left and right ends of the large support 9 are respectively fixedly installed with a first tenon support block 10 and a second tenon support block 14, a first blade support block 5 and a second blade support block 18, the connecting plate 1 is fixedly installed with a supporting block 4, and the supporting block 4 is fixedly installed with a blade crown supporting block 3.

[0020] A tenon pressing block 16 is hingedly mounted on the first tenon support block 10, and a first pressing screw 15 is screwed onto the tenon pressing block 16 for locking it on the second tenon support block 14. A tenon pressing block 13 is fixedly mounted on the bottom surface of the tenon pressing block 16, and the tenon side positioning block 11 and the tenon back positioning block 12 are both fixedly mounted on the left end of the large support 9, and the tenon side positioning block 11 and the tenon back positioning block 12 are located directly below the tenon pressing block 16, and a stopper 17 is fixedly mounted on the right end surface of the tenon pressing block 16;

[0021] A blade body clamping block 2 is hingedly installed on the first blade body support block 5, and a second clamping screw for locking it on the second blade body support block 18 is threadedly installed on the blade body clamping block 2. The blade crown side positioning block 6 and the blade body back positioning block 8 are both fixedly installed on the right end of the large support 9, and the blade crown positioning ball 7 is fixedly installed on the blade body back positioning block 8, and the blade crown side positioning block 6, the blade crown positioning ball 7, and the blade body back positioning block 8 are located directly below the blade body clamping block 2.
