In the process of machine tooling workpiece, the plane and two pits location is the most frequently used a kind of locate mode of workpiece.Six point location principles should be followed in the workpiece location in the anchor clamps; In order to prevent that crossing of workpiece from locating and the convenience of workpiece when loading and unloading, a sleeve clamp generally adopts a cylinder alignment pin and the location that the rhombus alignment pin is realized workpiece, is depicted as like Fig. 1 and 2 and uses the cylinder alignment pin to locate simultaneously; Workpiece 1 is fixed on the location-plate 6 through cylinder location key seat 2; Be inserted with cylinder alignment pin 3 in the cylinder location key seat 2, the below of cylinder alignment pin 3 is provided with locking nut 4, and 4 below of locking nut is provided with adjustment screw 5; Be depicted as use rhombus alignment pin location like Fig. 3 and 4; Workpiece 1 is fixed on the location-plate 6 through prismatic location key seat 8, is inserted with prismatic alignment pin 10 and holding screw 11 in the prismatic location key seat 8, and holding screw 11 compresses prismatic alignment pin 10 from the side; The below of prismatic alignment pin 10 is provided with locking nut 12, and 12 below of locking nut is provided with adjustment screw 13.When the lathe clamping workpiece, the location can occur because of considering workpiece, so the placement of cylinder alignment pin and prismatic alignment pin must placement as shown in Figure 5 on the anchor clamps: the formed corner angle 14 of the center of cylinder alignment pin and prismatic alignment pin chamfered edge are linked to be a line.Alignment pin is regulated the position length of alignment pin and workpiece through adjustment adjustment screw when mounted, when length adjustment to appropriate length, lock with locking nut then, avoid locating effective length and change, realize the location of workpiece.The chamfered edge corner angle direction of prismatic alignment pin is as shown in Figure 5, in order to control the chamfered edge corner angle direction of prismatic pin, on the prismatic location key seat, adds the rotation that a holding screw 11 prevents the prismatic alignment pin.In above-mentioned alignment pin application process, owing to assemble the lateral forces that the back alignment pin receives holding screw on the positioning seat, on microcosmic certain inclination can take place, can produce thus: 1, workpiece is not easy loading and unloading very much; 2, the product that comes out of machine tooling is defective, and positional precision has deviation.
The utility model content
The above-mentioned deficiency that the utility model uses the anchor clamps of alignment pin to exist to prior art provides a kind of anchor clamps that use alignment pin.
The technical scheme that the utility model solves the problems of the technologies described above is following: a kind of anchor clamps of alignment pin that use comprise cylinder alignment pin and prismatic alignment pin; Workpiece is fixed on the location-plate through cylinder alignment pin and prismatic alignment pin; It is characterized in that said cylinder alignment pin comprises the cylinder location key seat, have dowel hole and at least one screw hole on the said cylinder location key seat; Be inserted with the cylinder alignment pin in the said dowel hole; The bottom of said cylinder alignment pin is connected with the dish spring, is inserted with screw in the said screw hole, and said cylinder alignment pin closely contacts with the cylinder location key seat under the effect of screw; Said prismatic alignment pin comprises the prismatic location key seat; Have dowel hole and at least one screw hole on the said prismatic location key seat; Be inserted with the prismatic alignment pin in the said dowel hole; The bottom of said prismatic alignment pin is connected with the dish spring, is inserted with screw in the said screw hole, and said prismatic alignment pin closely contacts with the prismatic location key seat under the effect of screw.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, have dowel hole and three screw holes on the said cylinder location key seat, said three screw holes are arranged in triangle on the cylinder location key seat, and said dowel hole is positioned at leg-of-mutton center.
Further, have dowel hole and three screw holes on the said prismatic location key seat, said three screw holes are arranged in triangle on the prismatic location key seat, and said dowel hole is positioned at leg-of-mutton center.
The beneficial effect of the utility model is: the utility model uses the anchor clamps of alignment pin to eliminate the effect of holding screw to the alignment pin side force, and a series of influences to machine finish of avoiding thus being produced can also reduce the difficulty of workpiece loading and unloading on the lathe.
