Detailed Description
The clamp of the present invention will be briefly described with reference to the accompanying drawings.
Embodiment the utility model discloses the equipment and the use of anchor clamps
As shown in fig. 1 and 2, the vertical machining center milling fixture for machining a special-shaped piece comprises a fixture body 1, a positioning plate 3, a positioning mandrel 6 and a pressing plate 7; the fixture body 1 is of a U-shaped groove structure, and a positioning plate 3 is arranged on the bottom surface of the groove structure; the positioning mandrel 6 horizontally penetrates through the positioning plate 3 to be matched with a positioning hole at a positioning end 9-1 of the special-shaped piece, and the tail end of the positioning mandrel 6 is fastened by a nut 8, so that the special-shaped piece 9 is positioned; the pressing plate 7 is located in the groove-shaped structure and corresponds to the movable end 9-2 of the special-shaped piece, screw holes are correspondingly formed in the groove bottom of the clamp body 1 and the pressing plate 7 and are connected through bolts 2, and the movable end 9-2 of the special-shaped piece is pressed between the pressing plate 7 and the groove bottom face of the clamp body 1.
Specifically, the positioning mandrel 6 is fixed on the positioning plate 3 through a screw and is in clearance fit with the positioning plate 3. A slotted flat set screw 5 is preferably used to secure the positioning spindle 6 to the positioning plate 3.
