Detailed description of the invention
Describe the present invention below in conjunction with drawings and Examples.
The present invention utilizes tenon tooth shape locating, with positioning tooth block 20 with compress tooth block 21 limit blade on fixture along the Y direction free degree (blade axial freedom), because positioning datum is consistent with processing dimension benchmark, substantially increases machining accuracy.
As shown in Fig. 1-Fig. 9, the present invention includes chassis 1, chassis 1 is arranged bearing 1, bearing 29, bearing 1 and bearing 29 are installed on the two ends up and down of chassis homonymy respectively; Bearing 1 is arranged pressing plate 1, pressing plate 1 is arranged on bearing 1 by pin 24, and pressing plate 1 tail end is connected with bolt by pin 35, and bolts and nuts 1 coordinate;
Bearing 29 is arranged location-plate 10, pressing plate 2 12 is arranged on bearing 29 and locating piece 10 by bolt and nut, and positioning tooth block 20 is arranged on locating piece 10-by pin 4 18 and bolt two 19-.Compress tooth block 21 to be arranged on positioning tooth block 20 by eyelet bolt 1 and pin 1, realize blade and locate in fixture.
