Detailed description of the invention
By reference to the accompanying drawings, the present invention is described in further detail.
A kind of cutting tool assembly, is characterized in that: cutting tool assembly 10 comprises body part 12 and a cutting part 14; Cutting part 14 is the front part of this cutting tool assembly 10, comprises clamping part 16, one inserts retaining member 18, cutting insert 20 and a fixed component 22; Fixed component 22 is for being anchored to inserts retaining member 18 via a countersink head screw 24; The base pawl 26 that clamping part 16 comprises the top side 28 with composition first clamping surface, and the gripper jaw 30 of bottom side 32 with composition second clamping surface; There is a gap 34 between base pawl 26 and gripper jaw 30 and accept inserts retaining member 18.Be extended with slotted eye 36 from the rear section in gap 34, slotted eye 36 ends at an aperture 38, has towards rear and isolated two abutment surfaces, the abutment surface 42 bottom a top abutment surface 40 and being adjacent to slotted eye 36; Top abutment surface 40 and bottom abutment surface 42 are placed along a common imaginary line, and imaginary line is substantially perpendicular to the longitudinal axis of cutting part 14.There is the first locating surface 44 at the section place, rear being placed in adjacent gap 34, and it is vertically in the longitudinal axis of cutting part.Base pawl 26 is provided with pass through aperture mouth 46 and removes the inserts kept by inserts retaining member 18, inserts retaining member 18 comprises base pawl 2 48 and a gripper jaw 2 50, and between two pawls, define one in order to accept the inserts cover 52 of cutting insert 20, inserts bearing sleeve 52 is provided with the aperture 2 53 for undertaking one inserts apparatus for removing, aperture 2 53 can extend from the rear section of inserts bearing sleeve with direction backward haply with the use of, aperture 2 53 with through-pore 46.Base pawl 48 has the bottom side 2 54 that composition first clamps abutment surface, and clamping 2 50 has the top side 2 56 that composition second clamps abutment surface.Inserts retaining member 18 has haply with the elongation part 58 that backward directions extend, and extends part composition one fixed component.Inserts retaining member 18 is provided with the second right rearwards locating surface 60 at the rear being positioned base pawl 48, and inserts retaining member is provided with an inserts locating surface 62.Fixed component 22 is roughly trapezoidal shape, there is front aspect 64 and a rear aspect 66, and be undertaken in the recessed area 68 in the elongation part 58 of inserts retaining member 18, recessed area 68 has front aspect 2 70 and a rear aspect 2 72, and there is the shape being similar to fixed component 22 haply, rear aspect 2 72 forms the abutment surface of face forward.Fixed component 22 be provided with there is the first longitudinal axis 76 immerse oneself in through hole 74, and recessed area 68 is provided with the screwed hole 78 with one second longitudinal axis 80.
When retaining member is fully held in gap 34, and fixed component 22 is when being placed in recessed area 68, the displacement relatively mutually of first and second longitudinal axis linear system, according to this, when countersink head screw 24 be placed in immerse oneself in through hole 74 and be threaded into screwed hole 78 time, the front aspect 64 of fixed component 22 is against two abutment surfaces 40 and 42 spaced apart towards rear, and the rear aspect 66 of fixed component 22 is resisted against the rear aspect 2 72 of the recessed area 68 in inserts retaining member.So, at fixed component 22, between inserts retaining member 18 and body part 12, create three point contact configuration.When countersink head screw 24 is screwed tight, its conical nose 82 immerses oneself in the top portion of bellmouth against the cooperation of this screwed hole 78, and when the first longitudinal axis 76 moves towards the second longitudinal axis 80, is forced by fixed component mobile in direction upwards.Due to three point contact configuration and the trapezoidal shape of this fixed component, countersink head screw 24 is locked tighter, being applied to bed knife on inserts retaining member by fixed component can be larger, and this power applies against during the rear aspect 72 of recessed area 68 via the rear aspect 66 of fixed component.As Fig. 4, the thickness of fixed component 22 makes it towards the surface of outside, and the side edge surface of the substantial part 12 with body flushes.
