[0020] Such as Figure 1 And Figure 3As shown in the figure, a boring fixture for machining a spindle box includes a base plate 1 installed on a machine tool workbench, a clamping mechanism provided on the base plate 1 for fixing the spindle box, and positioning blocks 2 corresponding to the adjacent two side faces of the spindle box. In the present utility model, there are two positioning blocks 2, corresponding to the right side face and the rear side face of the spindle box respectively. A cushion plate 3 for supporting the bottom of the spindle box is provided on the base plate 1. When installing the spindle box, the bottom of the spindle box is supported by the cushion plate 3, and the position of the spindle box is positioned by the positioning blocks 2 on the right side face and the rear side face, ensuring the flatness of the bottom plane of the spindle box and the positions in the X and Y directions of the spindle box. The positioning is accurate, meeting the machining requirements of the spindle box in a horizontal machining center and ensuring the boring accuracy.
