    1476090 Parting-off tools W MIHIC 7 April 1975 [8 April 1974] 14088/75 Heading B3B A tool holding assembly for use in parting-off operations comprises a holder body 10 having a recessed seat portion 12 at one end for the reception of a cutting insert 15 and clamping means 18 the bottom surface 16 of the seat portion is of profiled cross section in the form of a 'V' the main portion of the surface being below and parallel to the top surface 14 of the holder body and the rear portion 13 of the surface being adapted to meet the top surface of the body, the V-shaped profile being constant throughout. The insert 15 and the clamping means 18 have complementary surfaces to the V-shaped profile which provided lateral support, the clamping means 18 having a nose portion 20 which engages in a recess 17 in the insert to rigidly secure the insert on the seating when the screw 22 secures the clamp 18. A pin 19 may be provided, which extends from the profiled surface, to guide the clamping means 18 during releasing and clamping of the means 18 by the screw 22. In the embodiment shown in Fig. 1 the front portion of the body 10 is formed as a blade projection 11 to point the cutting tool to be used as a parting-off tool. In the other embodiments the body 10 may be in the form of a blade member which is itself secured on a tool holder 31. The blade portion may also be located at right angles to the body portion as shown in Fig. 5. Reference has been directed by the Comptroller to Specification 1,392,026.

    (54) CUTTER
    one
    The invention relates to metal working.
    A known cutter containing a holder with a lowering relative to its upper surface is a horizontally disposed nest under the cutting edge and a clamping element with a fixing screw, the clamping element being in contact with the upper and rear edges of the insert ll.
    The disadvantage of this design is the unreliability of fastening the insert in the holder.
    The purpose of the invention is to increase the reliability of the fastening of the insert.
    In order to achieve this goal, the transitional part of the socket connecting its support surface with the upper surface of the holder is curved concave, and the clamping element is designed according to the shape of the socket and transitional part and fits tightly to them.
    In addition, the transition part is made V-shaped. In the lower part of the clamping element, on the side facing the cutting insert, a recess is made and a pin is placed therein, serving as an insertion stop and a centering element for the clamping element during its attachment.
    FIG. 1 shows a cutter, a longitudinal section; in fig. 2 - cutter, top view; in fig. 3 shows section A-A in FIG. one.
    The cutter consists of a holder 1 with an elongated part 2, on which there is a socket with a V-shaped groove 3
    0 across its supporting surface, with the socket on the back side made concave. This concave part 4 passes into the horizontal surface 5 of the holder 1. In the front part 5 of the slot, the cutting insert 6 is fitted with a profiled support surface 7 and a notch 8 in which the nose 9 of the clamping element 10 enters.
    The movement of the insert 6 in the opposite direction 0 is limited by a pin 11 mounted in the hole made in the holder 1. The bottom surface of the clamping element is also shaped, and its rear part is rounded according to the shape of the transition part 4. of the socket, in the clamping element 10 and the holder 1 threaded holes 12 and 13 for the fastening screw 14 with differently directed threads. Under the spout 9 in the clamping element 10 is made a groove 15 under the pin 11.
    The proposed design provides a reliable fastening of the cutting insert in the holder's socket.
    权利要求:
    Claims (3)
    [1]
    1. A cutter, preferably for cutting work, containing a holder with a lowering relative to its upper surface, a horizontally positioned nest under the cutting insert, and a clamping element with a fastening screw, the clamping element being in contact with the upper and rear edges of the insert, characterized in that in order to increase the reliability of the insertion hooking, the transitional part of the socket, with the “dyn kvda”, its bearing surface with
    the upper surface of the holder, is curved concave, and the fascia element is made in the shape of the socket and the transitional part.
    [2]
    2. Cutter according to claim 1, wherein: the transition part is V-shaped.
    [3]
