Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment discloses a two-linkage lathe fixture, as shown in fig. 1 and 4, the two-linkage lathe fixture comprises a flange plate 1, a sliding groove 9 is formed in the middle of the front end face of the flange plate 1, a pressing claw 2 is arranged in the sliding groove 9, the sliding groove 9 is matched with the pressing claw 2 along the longitudinal width, the sliding groove 9 is larger than the length of the pressing claw 2 along the transverse length, the outer side of the pressing claw 2 is close to the outer edge of the flange plate 1, the inner side of the pressing claw 2 is connected with the outer side of a clamping block 11, the pressing claw 2 is connected with a power head of a machine tool spindle through a bolt, the pressing claw 2 slides along the transverse direction under the driving of a hydraulic system, then the clamping block 11 is driven to slide along the transverse direction, and the clamping force of.
The lower part of the pressing claw 2 extends to be provided with a side seat 7, the lower edge of the side seat 7 is gradually inclined downwards from the outer side to the inner side, the triangular structure of the side seat 7 saves materials, and the pressing claw 2 and the side seat 7 are high in strength when matched.
The inboard of side seat 7 is connected with one side of base 10, the opposite side of base 10 is connected with one side of elastically positioned piece 3, the preceding terminal surface of base 10 is sunken backward for elastically positioned piece 3 and side seat 7, the cross-section of elastically positioned piece 3 one side is open-ended cyclic annular, the opening of elastically positioned piece 3 sets up towards the back, and open-ended size is 0.6mm, the upper end of elastically positioned piece 3 one side is equipped with locating hole 12, as shown in fig. 2, the opening part of elastically positioned piece 3 is filled and is equipped with elastic rod 5, effectively protects the opening clearance in the elastically positioned piece 3, prevents iron fillings, filth packing, prevents that anchor clamps from becoming invalid.
