The specific embodiment
An injection (mo(u)lding) machine 4 shown in Figure 1 in this injection (mo(u)lding) machine, is equipped with fixing mould binding 14 on a support 16.In addition, be provided with a guide rail 17 on support 16, at this guide rail, tighten intrinsic end plate 15 and movable binding 13 can be along this guide rail movement.Movable mould binding 13 is by elbow shaped rod mechanism 20 rectilinear motions, thereby the die cavity be formed between each mold halves 18 of mould is closed.Elbow shaped rod mechanism 20 is driven by a drive unit 3, wherein, the first member 1(screw mandrel) by preferred motor, drive, can move and drive point-blank second component (crosshead) along machine axis point-blank with the transmission device 12 of a feed screw nut's form be not shown in further detail.By this linear drives, the bar of elbow shaped rod mechanism 20 is correspondingly moved and pivotable, thereby movable mould binding 13 move along beam 19.Overload particularly when drive unit 3, during in terminal location or during the handling error at other, occurs, in the various parts of the whole power train that this overload may be between transmission device 12 and mold halves 18, cause damage.Because damage mostly because little straight line force is more not serious, so recognize in the present invention, particularly prevents the high revolving force occurred when overload in rectilinear motion.These high revolving forces particularly occur in the zone of the first member 1, because this first member no longer can continue rectilinear motion when the generating function fault and the friction by transmission device 12 causes thus revolving force may particularly exert an influence to the connection between the first member 1 and second component 2 devastatingly.
In order to address this problem, a kind of first flexible program of a clutch 5 shown in Figure 2.At this, the first member 1(screw mandrel) there are a plurality of parts on the end at it away from transmission device, wherein, by a tightening member 24(soket head cap screw) receiving element 22 is clamped between fastening means 24 and the first member 1.Fastening means 24 is connected with the first member 1 by screw thread 25.Be fastened with retaining ring 21 by tightening member 23 again on receiving element 22.These parts 1,24,22,21 and 23 are when normal load N and in overload
Always along with motion each other.
In second component 2(crosshead) on flange 29 additionally is installed, clamping element 30 can be screwed on this flange and can be fixed by fastening means 39.Preferably the friction element 27 of annular is fastened on clamping element 30 by tightening member 28.And the friction element 26 of same annular directly is fastened in the first member 1 by tightening member 40.In order to guarantee the power transmission of straight line between the first member 1 and second component 2, clamping element 30 is screwed into, until receiving element 22 and retaining ring 21 clamp between described two friction elements 26 and 27, thereby the rubbing surface 6 of parts 21 and 22 abuts on the rubbing surface 6 of friction element 26 and 27.
When normal load N, the first member 1 rectilinear motion and can---according to transmission device 12, which direction to apply straight line force L along---and correspondingly make second component 2 rectilinear motions.Once but overload occur
This is crossed to be loaded in the first member 1 and can aware as undesirable high revolving force R, and in whole power train, the sealed Joint failure of the most weak connecting portion, i.e. friction between rubbing surface 6 and the parts that are fixedly connected with the first member 1 may rotate around axis A with respect to the parts that are fixedly connected with second component 2.Once due to overload
The high revolving force R occurred again weakens and is reduced to the frictional force produced lower than between each rubbing surface 6, again can proper motion.Therefore by not occurring breaking-up in the join domain of sealed clutch 5 between the first member 1 and second component 2 that rub, this clutch forms by friction element 26 and each rubbing surface 6 27 and retaining ring 21 and receiving element 22.
Fig. 3 to 8 illustrates a kind of embodiment of the present invention, replaces in this embodiment a sealed clutch 5 of friction to use a clutch 5 that shape is sealed.
This is drawn in Fig. 3 to the first member 1 and second component 2 when normal load N.On the first member 1, straight line force L also is applied to the first member 1 from a unshowned transmission device 12.Receiving element 31 is fixedly connected with the first member 1, and this receiving element is by tightening member 24(soket head cap screw) clamp regularly.Be fastened with clutching member 7 by tightening member 32 on receiving element 31, this clutching member is configured to the ring of gear shape, and wherein, the tooth 33 of this ring is engaged in the tooth 33 of clutching member 8, and this clutching member is configured to annular gear equally.This clutching member 8 is loaded power by a 11a of the energy storage device with the disk spring form again, and wherein, this energy storage device 11a is supported on the spring pedestal 38 be connected with receiving element 31 regularly.
In second component 2(crosshead) above by tightening member 37, be fastened with equally a clutching member 9, this clutching member is configured to annular gear.This clutching member 9 also is bonded on the tooth 33 of clutching member 8 by the tooth 33 of this gear.Also be connected with the spring pedestal 34 for energy storage device 11b by Connection Element 35 and tightening member 36 on second component 2.This energy storage device 11b with the disk spring form acts between spring pedestal 34 and clutching member 8.Clutching member 7,8 and the 9 common sealed clutches 5 of shape that form.
Being matched with this place in Fig. 6 can find out, how clutching member 7 or 9 tooth 33 are engaged in the tooth 33 of clutching member 8, and wherein, tooth 33 has respectively the flank of tooth 10 of inclination in side direction.
If occur as shown in FIG. 7 the overload of the revolving force R form to be caused by the first member 1 now
Clutching member 7 or 9 moves and also moves away from clutching member 8 along rectilinear direction L at this along direction of rotation.This reaches by the flank of tooth 10 tilted.
In Fig. 8, high revolving force R causes that clutching member 7 or 9 separates fully with clutching member 8 and therefore throws off.In this implements flexible program, thus not only occur clutch 5 rotation disengagement and also the disengagement of part straight line appears.At this, revolving force R not only must overcome the frictional force between each flank of tooth 10, and must, to energy storage device 11a or 11b acting, by Figure 4 and 5, can be found out.
Shown in Figure 4 a kind of when the first member 1 no longer can continue to move right situation.The revolving force transmission improved from transmission device 12 to first members 1 and the parts that are fastened thereon thereof thus.By the disengagement as shown in Fig. 7 and 8, clutching member 8 overcomes the frictional force and the power that overcomes energy storage device 11a (or according to rotation direction difference left) motion to the right between the flank of tooth 10, until clutch 5 is thrown off fully, and the parts that revolving force R can make the first member 1 be fastened thereon together with it idle running, and do not cause damage.At this, in the situation that extruding energy storage device 11a second component 2 moves right with respect to the first member 1.
Shown in Figure 5 in contrast to this, straight line force L is applied to the first member 1 together with on its parts by the left side.In contrary mode, power also can be applied on second component 2 by the right.Once situation is like this, clutching member 8 is in the situation that extruding energy storage device 11b moves, so clutching member 8 unclamps with clutching member 9.Thus second component 2 with respect to the first member 1 to left movement.For the overload of pure straight line, energy storage device 11a and 11b are enough.But, when the overload of main rotation occurring, only energy storage device 11a and 11b can not stop breaking-up.But the overload power by the rotation that occurs in the zone at the flank of tooth 10 can by or clutching member 7 or clutching member 9 with clutching member 8(also in the situation that overcome the power of energy storage device 11a or 11b) get loose, thereby in the situation that according to Fig. 4, clutching member 8 is not along with the revolving force associated movement of the first member 1, and in the situation that, according to Fig. 5, clutching member 8 is along with the revolving force associated movement of the first member 1.Therefore, second implements flexible program has following advantage, that is, not only in the overload of rotation, can realize according to disengagement of the present invention, and the overload that is additional to rotation is also considered the overload of the pure straight line occurred in the join domain between the first member 1 and second component 2.
