Detailed ways

1 to 3, the present utility model discloses a clamping structure of a multi-angle rotating vise. The vise has a vise base 1, the vise body 2 is mounted on the vise base 1 and can be rotated 360 degrees to adjust the processing angle, The clamp body 2 is a square block. The upper end surface of the clamp body 2 is provided with a clamp block 1 3 and a clamp block 2 4 for clamping the workpiece. The clamp block 1 3 is fixed on the left end of the clamp body 2. Of course, clamp block 1 3 can also be made movable, but the cost is high and it is unnecessary. The clamping block 2 4 can slide along the clamping body 2 through the guiding sliding mechanism arranged between the clamping block 2 4 and the clamping body 2. Block one 3 and clamp block two 4 are provided with a pair up and down opposite to each other, so that multi-clamping workpiece processing can improve efficiency. 6. The clamp body 2 is located in the clamping block groove 5. The inner wall of the clamping block groove 5 is provided with a dovetail groove 7 that cooperates with the dovetail block 6. Of course, the above is only a design. We can also use V-shaped grooves and V-shaped grooves. A dovetail block 6 is provided on the inner wall of the clamping block groove 5 and a dovetail groove 7 is provided on the side of the clamp body 2 .

The clamp body 2 is provided with a main groove 8, the main groove 8 penetrates the upper and lower end surfaces of the clamp body 2, the inner wall of the main groove 8 is provided with an adjustment chute 9, and the upper groove wall of the adjustment chute 9 is provided with several positioning Slot 10, the clamping block two 4 is provided with an oblique rod hole 11 passing through the clamping block two 4 and a locking screw 12 located in the oblique rod hole 11. Generally, the preferred angle of the oblique rod hole 11 is 45 degrees with the horizontal plane, and The oblique rod hole 11 is not a standard round hole, because the locking screw 12 needs a rotation space, so the oblique rod hole 11 is a trumpet-shaped flat hole with a narrow top and a wide bottom. The end of the locking screw 12 is provided with a locking block 13. And the locking block 13 is provided with a locking screw hole 14 that cooperates with the locking screw 12, the locking block 13 is oppositely provided with an adjusting sliding rod 15, and the adjusting sliding rod 15 is located in the adjusting chute 9 and can be adjusted. The locking screw 12 is pulled into the corresponding positioning groove 10, the clamping block 24 is provided with a universal groove, the inclined rod hole 11 is located on the groove bottom of the universal groove, and the locking The screw 12 is provided with a universal head 16 that cooperates with the universal groove, so when the locking screw 12 is locked with the locking block 13, the locking screw 12 squeezes the clamping block 24 through the universal head 16, thus The clamping block 2 4 will move and drive the locking screw 12 to move, but the locking screw 12 is stuck in the positioning slot 10 by adjusting the sliding rod 15, so in order to ensure that the locking screw 12 is not stuck in the oblique rod hole 11, The locking screw 12 will rotate with the movement of the clamping block 2 4 , thereby driving the locking block 13 and the adjusting sliding rod 15 to rotate around the positioning groove 10 , and the locking screw 12 will keep pressing with the clamping block 2 4 during the rotation process. The contact is achieved through the universal groove and the universal head 16 . In the present application, the universal groove is a semicircular groove, the universal head 16 is a hemisphere, the universal head 16 is provided with a hemispherical surface matching with the semicircular groove, and the locking screw 12 passes through the hemispherical surface.

As shown in the figure, in order to facilitate the processing of the positioning groove 10, the positioning groove 10 is a semi-circular groove, and we need to drill holes from the outside of the clamp body 2, so the clamp body 2 is provided with a through hole 17 passing through the main groove 8, And the end part of the through hole 17 communicates with the adjusting chute 9 , and another part of the end of the through hole 17 forms a semicircular groove on the groove wall of the adjusting chute 9 .

Brief description of the working principle of this clamping structure: first loosen the locking screw 12, then pull the clamping block 2 4 to slide along the clamp body 2 to a predetermined position, then put the workpiece in, start to lock the locking screw 12, lock the The tightening screw 12 moves along the inclined rod hole 11, and at the same time, the adjusting sliding rod 15 is clamped into the positioning groove 10, and then the locking screw 12 is moved by the universal head 16 to squeeze the second clamping block 4 to clamp the workpiece.
