Abstract
The utility model relates to a machine tool fixture, in particular to a flat-pressing type cutting knife fixture. The flat-pressing type cutting knife fixture is characterized by comprising a knife back body, a hook-shaped pressing plate, a positioning support pin and a compression screw, wherein one side of the knife back body is provided with a cutting knife groove for installing a cutting knife, and the upper end of the knife back body is provided with the positioning support pin and a fastening screw hole; the hook-shaped pressing plate is positioned through the positioning support pin and is connected with the knife back body through the compression screw and the fastening screw hole; and the cutting knife is fastened into the cutting knife groove through the hook-shaped pressing plate. When the flat-pressing type cutting knife fixture is used, various specifications of cutting knifes can be installed on a knife back as required to cut off workpieces on a lathe. The flat-pressing type cutting knife fixture is used for the low-speed cutting of various shapes of outer grooves and section grooves and can also be used for low-speed turning of smaller-diameter excircles and external threads with a smaller screw pitch. The flat-pressing type cutting knife fixture has the advantages of compact structure, convenience in manufacture, large clamping force, firmness, durability and the like. According to the flat-pressing type cutting knife fixture, rectangular blades with thickness of more than 3mm can be firmly pressed at the bottom of the knife back, and various specifications of rectangular blades can be respectively installed.
Description
Technical field
The utility model relates to jig, particularly a kind of easy for installation, good positioning effect, the flat-crushing type rectangle high-speed steel cutting knife anchor clamps that are specially adapted to lathe that result of use is good.
Background technology
As everyone knows, anchor clamps are extremely important in machining, and anchor clamps not only are related to operating efficiency, labour intensity; Also connect the quality that influences processing work at least, the cutting knife anchor clamps are directly to be fixed on the lathe swivelling tool-holder through screw now, and cutting knife is installed in the cutoff knife rack groove; Rely on the upper surface of the coupling mechanism force extruding cutoff knife rack of screw to come solid cutting knife, this cutting knife anchor clamps often occur shaking cutter, collapse the cutter phenomenon, Chinese patent CN201586766U discloses a kind of cutting knife anchor clamps; It is characterized in that comprising top board, jig main body, lower platen; Soket head cap screw, the auxiliary locking of centering type handwheel; Wherein, the top that top board is placed on jig main body tightens up, and the below that lower platen is placed on jig main body tightens up; Two the auxiliary locking of centering type handwheels are placed in two counterbores of top board, and two soket head cap screws are cascaded top board, jig main body, lower platen and two the auxiliary locking of off-centre handwheels.The deficiency of this cutting knife anchor clamps is complex structure, inconvenient operation.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes above-mentioned prior art, and a kind of simple in structure, easy to operate, good stability, the fixing and good flat-crushing type tool of processing effect are provided.
The utility model can reach through following measure:
