Detailed Description

The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

The utility model provides an eccentric tool, including base 1, slip table 2, adjusting bolt 6, fastening bolt 8, fastening nut 9.

As shown in fig. 8, the left end face of the sliding table is provided with a sliding block 4, the sliding block is trapezoidal, the right end of the sliding table is provided with a connecting hole 10, the side face of the sliding table is also provided with a plurality of fixing holes 12 (used for installing and connecting bolts to fix a workpiece) for connecting the connecting holes, the inside of the sliding table is also provided with bolt insertion holes 11 which are axially arranged, and the bolt insertion holes penetrate through the left end face of the connecting hole and the left end face of the sliding block.

As shown in fig. 6, the right end face of the base is provided with a chute 3, the shape of the chute is suitable for the appearance of the sliding block (the cross section is trapezoidal), the bottom surface of the chute is provided with a strip-shaped hole 7, the left cavity 1.1 of the base is communicated with the chute through the strip-shaped hole, the side face of the base is provided with an adjusting screw hole 5, the adjusting screw hole is communicated with the chute, and an adjusting bolt 6 is installed in the adjusting screw hole. The axes of the sliding groove, the strip-shaped hole and the screw hole are parallel to each other and perpendicular to the central axis A of the base.

The sliding table is adjustably mounted at the right end of the base. As shown in fig. 3, the fastening bolt is inserted into the bolt insertion hole from right to left, then passes through the strip-shaped hole and is engaged with the fastening nut arranged in the cavity of the base, at the moment, the left end surface 2.1 of the sliding table is tightly attached to the right end surface of the base, and the two inclined surfaces 4.1 of the sliding block are tightly attached to the two side groove walls of the sliding groove, so that the stable connection of the base and the sliding table is realized through the positioning of the two surfaces.

The right-hand member face of base is equipped with the scale, and the slip table side is equipped with the indicating line.

The operation method of the utility model is as follows:

firstly, a workpiece 20 is installed on the sliding table, the workpiece is inserted into a connecting hole of the sliding table, and then the workpiece is fixed by using a connecting bolt; when the eccentric position is adjusted, the fastening nut is loosened, the adjusting bolt is rotated to push the sliding table to move transversely (the sliding table moves along the radial direction of the base) to adjust the eccentricity, the positions of the indicating lines and the scales are observed simultaneously, and the fastening nut is screwed down after the sliding table moves in place to start machining operation.
