Embodiment Construction
[0017] The present invention will be further described below in combination with specific embodiments.
[0018] Fig. 1(a) and Fig. 1(b) are the front view and front view of the traditional model drill bushing. In the figure 1 is the traditional model made on the curved surface, 2 is the part with one side of the curved surface, and 3 is the traditional no-angle Drill sleeve, 5 is the theoretical vector line of the part drilling, 6 is the vector line of the actual process hole.
[0019] A guide type embedded drill sleeve, the main body of the drill sleeve is cylindrical, with a sleeve cap 4-1 with a thickness of 2mm, and a groove on the cylindrical surface that is in contact with the traditional sample plate 1 made on the curved surface 4-2, the cross section of the groove 4-2 is triangular, the wedge angle formed by the outer surface of the groove 4-2 and the vertical surface is 75°, and the drill sleeve and the template 2 are interference fit.
