Detailed description of the invention
Please join shown in Fig. 1, be the automatic tool changer 100 of the toolroom machine of a preferred embodiment of the present invention,
It includes a column the 10th a, mandrel the 20th a, cutterhead the 30th, multiple cutter holder groups 40 and a re-setting device
50.Wherein, each cutter holder group 40 is for clamping one knife bar S.
This column 10 is internal is provided with the main shaft 12 that can axially move back and forth, as in figure 2 it is shown,
This knife bar S can be captured to carry out as attacked spiral shell in this cutter holder group 40 when this main shaft 12 moves down
Operation is processed in line or boring etc..This mandrel 20 is non-rotatably arranged on this column 10 side.
This cutterhead 30 is pivotally socketed in this mandrel 20, in the present embodiment, and this cutterhead 30
It is to be rotated by a barrel cam 32.
Described cutter holder group 40 is to arrange along the periphery of this cutterhead 30 in equidistant mode, please coordinate
Shown in Fig. 3 to Fig. 6, each cutter holder group 40 includes a cutter holder base the 41st a, guide plate the 42nd a, jig arm
43rd, an elastic component the 44th a, movable part the 45th, a self-lubricating bearing 46 and a top retainer component 47.Wherein, should
Cutter holder base 41 is fixed on this cutterhead 30, and has two pivot ear 41a；This guide plate 42 passes through two bolts
48 and be incorporated into this cutter holder base 41 in a detachable fashion, this guide plate 42 side is formed with an arc
Guiding face 42a, and the pod 42b of a recessed dome shape on this guiding face 42a.Another is mentioned that,
This cutter holder base 41 can also be integrally formed with this guide plate 42.
The jig arm 43 of this cutter holder group 40 is passed through by a pivot pin 49 and is articulated in being somebody's turn to do of this cutter holder base 41
Between two pivot ear 41a, and can be in primary importance P1 shown in Fig. 1 and one second shown in Fig. 2
Pivot pendulum between the P2 of position.The two ends of this jig arm 43 are respectively a jaw 431 and a central siphon 432, its
In this jaw 431 be used for clamping this knife bar S, and make this knife bar S get loose when this main shaft 12 moves down,
Otherwise, when moving on this main shaft 12, this jaw 431 clamps this knife bar S again automatically；This jig arm
This central siphon 432 of 43 is then directed towards this cutter holder base 41.This jig arm 43 separately has a guide pillar 433 and connects
In body portion, this guide pillar 433 one end is provided with a rolling member 434, this rolling member 434 can be bearing but not
As limit.
This elastic component the 44th, movable part the 45th, self-lubricating bearing 46 of this cutter holder group 40 with top retainer component 47 is
It is together positioned in this central siphon 432 of this jig arm 43.Wherein, this elastic component 44 is a spring, its
One end is butted on the inwall of this central siphon 432；As it is shown in figure 5, this movable part 45 cylindrical and in two
End is respectively provided with an a depression 45a and recess 45b, and the other end of this elastic component 44 is i.e. that to be butted on this recessed
In the 45a of cave；This self-lubricating bearing 46 is sheathed between this central siphon 432 and this movable part 45；This contact
Part 47 is that a steel ball is positioned in this recess 45b of this movable part 45, and this recess 45b has surely
The effect of this steel ball position fixed, the part beyond this steel ball exposes to this central siphon 432 constitutes a sphere head
Portion 47a, receives the effect of this provided jacking force of elastic component 44 between this steel ball, and with mobilizable
Mode maintains and moves toward this guide plate 42 direction.
This re-setting device 50 is installed in this column 10 side, and it includes a pull bar being reciprocally moveable
52, in the present embodiment, this re-setting device 50 is the cylinder pressure (such as pneumatic cylinder or oil hydraulic cylinder) that stretches.
One end that this pull bar 52 exposes is provided with an overhead kick 54, and this pull bar 52 moves back controllably inside cylinder pressure
Move, contact so that this overhead kick 54 inner face maintains with this rolling member 434.Should be noted that, in order to
Drive the mechanism that this pull bar 52 is retired in addition to aforesaid flexible cylinder pressure, also obtain returning by spring
Multiple power is reached.
Please coordinate shown in Fig. 1 and Fig. 6, be to represent the state that the main shaft 12 of this column 10 not yet moves down,
The jig arm 43 of now all of cutter holder group 40 is all positioned at this primary importance P1, the ball of each top retainer component 47
Face head 47a is then to be butted in the pod 42b of this guide plate 42, and by the top of respectively this elastic component 44
Push away effect, it can be ensured that jig arm 43, when this cutterhead 30 rotates, will not cutter holder base 41 occur not relatively
When rock.
Please coordinate again shown in Fig. 2, moved down and captured by control at position this cutterhead 30 at this main shaft 12
During the knife bar S clamped by cutter holder group 40 of low level, the jig arm of the crawled cutter holder group 40 of this knife bar S
43 are elapsed by this main shaft 12, cause its top retainer component 47 and leave pod 42b and along with this guide plate 42
Guiding face 42a and pivot are put to this second place P2.Now this jig arm 43 is by its guide pillar 433
Rolling member 434 and the pull bar 52 of this re-setting device 50 is down pulled out.But at this main shaft 12 again
Secondary moved so that during tool changing by control is upper, this pull bar 52 by its re-setting device 50 control and towards in cylinder pressure
When portion retires, catch on the rolling member 434 on this guide pillar 433 by this overhead kick 54, with by this jig arm
43 pull toward this primary importance P1 from this second place P2, until the sphere head 47a of top retainer component 47
Till being again butted on the pod 42b of this guide plate 42.
In above-mentioned, each cutter holder group 40 is a modular construction, is not only adapted to a large amount of and quickly produces,
Also easy access is changed.Secondly, the jig arm 43 of each cutter holder group 40 pivot pendulum when tool changing operation
Action, is brought the probability of friction indirectly for this cutter holder base 41, with other cutter holder groups 40 quite,
So the service life of each cutter holder group 40 can be promoted.
Another is mentioned that, in each component of above-mentioned cutter holder group 40, and wherein this guide plate 42 and this contact
The hardness of part 47 is all more than the hardness of this cutter holder base 41 and this jig arm 43.More specifically, volume
Bigger cutter holder base 41 and jig arm 43 are that the material with light weight is made, such as aluminium, whole to reduce
The weight of cutter holder group 40, and the burden ordering about the drive mechanism that cutterhead 30 rotates can be mitigated.And this is led
Because contact condition must be kept between plate 42 and this top retainer component 47, therefore the material is selected with firm wear-resisting to be
Main, such as iron material, thus to reduce because of brought problem of wearing and tearing.
The foregoing is only the preferable possible embodiments of the present invention, every application description of the invention and
The equivalence change that claim is done, ought to be included in scope of the presently claimed invention.
