Fig. 2 illustrates the tool fixing device 10 with the machining tool 18 in insertion tool fixture 10.This tool fixing device 10 comprises an operation housing 56.Operator can operate this operation housing 56 with the machining tool 18 in clamping and/or back off tool fixture 10.In addition, tool fixing device 10 comprises a clamping unit 12, and this clamping unit has one first clamping element 14 and one second clamping element 16 (Fig. 3), and these clamping elements 14,16 are arranged for and clamp machining tool 18 in a clamped position.
Fig. 3 illustrates the clamping unit 12 in clamped position.This machining tool 18 is coupled with reciprocating lever 52 in this mating reaction by the clamping area 22 of clamping element 14,16 and reciprocating lever 52.Clamping element 14,16 loads machining tool 18 with chucking power (Fig. 4) on the direction of clamping area 22.Machining tool 18 is sandwiched between clamping element 14,16 and clamping area 22 thus.In addition, in clamped position, the holding element 96,98 of machining tool 18 is supported on clamping element 14,16.Observe along instrument direction of insertion 60, the holding element 96,98 of machining tool 18 is arranged on after clamping element 14,16 in clamped position.The direction that machining tool 18 extends on the contrary along one with instrument direction of insertion 60 thus in clamped position is fixed by clamping unit 12.
In addition, clamping unit 12 has a swing unit 20, and this swing unit is arranged for and clamping element 14,16 is swung relative to the clamping area 22 of clamping unit 12.Swing unit 20 has a chute guide frame 24, and this chute guide frame is arranged for and along the translational motion of instrument direction of insertion 60, clamping element 14,16 is swung relative to clamping area 22 according to swing unit 20.Clamping element 14,16 is constructed to rolling element 26,28.At this, clamping element 14,16 is constructed to needle roller 30,32.Therefore, clamping element 14,16 respectively has a rotation 92,94.The rotation 92,94 being configured to the clamping element 14,16 of needle roller 30,32 swings relative to clamping area 22 in the plane extended perpendicular to clamping area 22 by chute guide frame 24.At this, rotation 92,94 swings opposite each other.
Chute guide frame 24 is arranged in the director element 78 of swing unit 20.The operation housing 56 that director element 78 is arranged on tool fixing device 10 is inner.The outer wall of this outer guide member 78 rests on the inwall of operation housing 56.Therefore the motion operating housing 56 can be delivered on director element 78.Chute guide frame 24 also comprises the chute track 66,68 that two are configured to groove 62,64.Groove 62,64 has the trend tilted relative to instrument direction of insertion, and this trend departs from 90 ° of angles and extends.That this trend can be configured to arc and/or be made up of the trend of a straight line tilted relative to instrument direction of insertion 60.
Clamping element 14,16 is respectively directed in groove 62,64 by an end 70,72.In addition, clamping element 14,16, the end 74,76 that deviates from the end 70,72 be directed in groove 62,64 is arranged in the dead slot 80,82 of clamping unit 12 respectively movingly.When swing unit 20 from clamped position against 60 translational motion of instrument direction of insertion time, clamping element 14,16 is moved away from clamping area 22 by the guiding in groove 62,64.Clamping element 14,16 can roll along the fringe region to groove 62,64 gauge of swing unit 20 when swing unit 20 moves.
Clamping unit 12 has a spring element 34 in addition, and this spring element is arranged for pre-tensioner swing unit 20.In clamped position, swing unit 20 is loaded the spring force of spring element 34 along instrument direction of insertion 60 by spring element 34.Thus, clamping element 14,16 is loaded confining force by the mating reaction of the groove 62,64 of spring element 34 and chute guide frame 24 on the direction of clamping area 22.This spring element 34 is constructed to compression spring 84.Spring element 34 conforms with at this and is arranged on functionally between the stopping element 36 of clamping unit 12 and the director element 78 of swing unit 20.An end 86 of spring element 34 is supported on director element 78.Another end 88 of spring element 34 is supported on (Fig. 4) on stopping element 36.Stopping element 36 is arranged for and clamping element 14,16 is remained on (Fig. 7) in instrument insertion position in a running status.
Stopping element 36 has two motion arms 38,40, and these motion arms can operate to trigger the clamping process of clamping unit 12 by machining tool 18.The extension size that motion arm 38,40 is parallel to spring element 34 along instrument direction of insertion 60 extends.In addition, each side being arranged on spring element 34 in two motion arms 38,40.Therefore, along the direction observation that extends perpendicular to instrument direction of insertion 60, spring element 34 is arranged on (Fig. 5 and 7) between motion arm 38,40.Motion arm 38,40 respectively has the partial sector of an arc, and this partial sector is bent upwards in the side of clamping area 22.The operation section 90 that machining tool 18 extends with taper when inserting along instrument direction of insertion 60 operates stopping element 36 by motion arm 38,40.The operation section 90 that taper extends contacts with the partial sector of the arc of motion arm 38,40 when machining tool 18 is inserted into.
From the clamped position shown in figures 4 and 5 of clamping unit 12, clamping unit 12 can be transferred in instrument insertion position by the motion of the operation housing 56 of tool fixing device 10 by operator.At this, machining tool 18 is removed from tool fixing device 10 by clamped position.Operation housing 56 is here driven on the direction contrary with instrument direction of insertion 60 by operator.Director element 78 is same thus to move upward in the side contrary with instrument direction of insertion 60.Spring element 34 is compressed and loaded a power to stopping element 36 on the direction of clamping element 14,16.Due to the motion of director element 78, clamping element 14,16 moves away from clamping area 22 by the groove 62,64 of chute guide frame 24.Clamping element 14,16 swings relative to clamping area 22 due to the motion in groove 62,64, until the rotation 92,94 of clamping element 14,16 is substantially perpendicular to clamping area 22 orientation.
Stopping element 36 moves (Fig. 6 and 7) until a shoulder (not shown at this) of stopping element 36 rests on clamping element 14,16 due to the spring force of spring element 34 between clamping element 14,16.Due to the motion of stopping element 36, machining tool 18 is dished out from clamping unit 12 by the partial sector of the arc of motion arm 38,40 at least in part by the spring force of spring element 34.Director element 78 is loaded spring force by spring element 34 along instrument direction of insertion 60.Director element 78 to be prevented from along moving of instrument direction of insertion 60 by the stopping element 36 be arranged between clamping element 14,16.Stopping element 36 is gripped between clamping element 14,16.At this, stopping element 60 is loaded on the direction extended against instrument direction of insertion 60 by the spring force of spring element 34.Therefore, clamping element 14,16 is prevented from along the moving of groove 62,64 of chute guide frame 24.In addition, clamping element 14,16 is prevented from relative to the oscillating motion of clamping area 22.Clamping unit 12 is thus in instrument insertion position, and in this instrument insertion position, machining tool 18 can be inserted in clamping unit 12 by operator.
When along instrument direction of insertion 60 by machining tool 18 insertion tool fixture 10 and/or clamping unit 12 time, stopping element 36 shifts out along instrument direction of insertion 60 by machining tool 18 between clamping element 14,16.The conical region of machining tool 18 contacts with the partial sector of the arc of motion arm 38,40 when machining tool 18 is inserted into.Therefore, the motion of machining tool 18 is passed on stopping element 36.Spring element 34 is compressed along moving of instrument direction of insertion 60 due to stopping element 36.Therefore director element 78 is loaded the spring force of spring element 34 along instrument direction of insertion.Therefore, director element 78 moves along instrument direction of insertion 60 together with operation housing 56.Clamping element 14,16 by chute guide frame 24 groove 62,64 toward each other and swing relative to clamping area 22 ground.At this, the rotation 92,94 of clamping element 14,16 along one perpendicular to instrument direction of insertion 60 and the direction being parallel to clamping area 22 swing.Machining tool 18 is fixed clamping after the oscillating motion of clamping element 14,16.Machining tool 18 is gripped between clamping element 14,16 and clamping area 52.Machining tool 18 is coupled with reciprocating lever 52 thus.The holding element 96,98 of machining tool 18 is supported on clamping element 14,16.Clamping unit 12, therefore in clamped position, can carry out processing work by the machining tool 18 be clamped in this clamped position.
