Description
Technical field
The present invention relates to of the connection of a mechanical part to another.In a preferred embodiment, the present invention relates to a part for example connection of excavator bucket of chafing strip to excavating gear.
Background technology
Known mechanical is excavated and excavating gear stands noticeable wear in mining and digging are operated, and weares and teares mainly by to excavator bucket, and the high friction and the abrasion of soil biting instrument and similar component cause.Correspondingly, the part of this member can be only changed in general expectation, and whole device of nonessential replacing or whole parts.
In order to overcome the wearing and tearing of these members, be known that partly to be attached to replaceable abrasionproof at the edge or the edge of the parts of high wear is stood in other surface.
The usual method that links the abrasionproof part is simply abrasionproof partly to be welded on the surface of parts.This has following shortcoming, promptly removes the operation more complicated of abrasionproof part of wearing and tearing and consuming time subsequently.Because the time span of parts shut-down operation when changing its abrasionproof part, this causes efficient and productivity ratio to reduce inevitably.
Also proposed abrasionproof partly is attached to the mechanical device of device, usually comprised and use pin or bolt.It is invalid that this in practice method often also is proved to be, because pin or bolt are easy to owing to the active force that applies on abrasionproof part and device that they were attached to is out of shape.The distortion of pin or bolt makes abrasionproof partly be difficult to from the device device isolation usually, thereby causes production time loss and overall efficiency lower once more.
Thereby expectation can partly be attached to the excavating gear parts with abrasionproof with rigid manner and not fluff during operation such as excavator bucket abrasionproof part.Also during operation after it stands stress, it has the ability that can easily remove the abrasionproof part especially in expectation.
The present invention attempts to provide a kind of effective coupling assembling that satisfies these expectations at least in part.
Summary of the invention
According to one aspect of the present invention, a kind of coupling assembling that is used for first member is connected to second member is provided, this second member has the recess that outstanding protuberance and first member have complementary shape, wherein this first member has first area supported of association and second area supported that second member has association, this first and second area supported in use by tapered gap relatively with separate, this coupling assembling also comprises the locking member of wedge shape, the size of this wedge lock member is suitable for being positioned in this tapered gap, and drive unit, this device is arranged in tapered gap fastening or loosen locking member.
In a preferred embodiment, first member is that abrasionproof part or chafing strip and second member are the part that the chafing strip of mechanical device part is linked to this, for example excavator bucket.
Further preferably, provide a pair of coupling assembling to be used for that this first member or each first member are attached to second member.
Advantageously, even the present invention allows also easily to remove and change the abrasionproof part after abrasionproof partly stands remarkable stress.

The specific embodiment
With reference to each figure, be used for shown in it first member is connected to for example coupling assembling 10 of excavator bucket 14 of second member such as chafing strip 12.In the drawings, two this coupling assembling 10a and 10b are shown at the opposed end place of chafing strip 12.
Each coupling assembling 10 includes outstanding protuberance 16 that is positioned on the excavator bucket 14 and the complementary recess 18 that is positioned at chafing strip 12.Each outstanding protuberance 16 is substantially rectangle, and is formed by vertical wall 20.Wall 20 almost surrounds interior zone 22.In case wall 20 has a part that chafing strip 12 is connected to excavator bucket 14 just in use towards the gap 24 of the end of chafing strip 12 orientation.Along the rectangle that forms protuberance 16 each is long-armed, wall 20 has the outside and inboard.First outside 17 is positioned on the wall part that extends away from gap 24.Second outside 19 is positioned on the relative wall part.The first inboard 21a is positioned on the wall part identical with first outside 17, only towards interior zone 22 orientations.The second inboard 21b is relative with the first inboard 21a, and is positioned on the wall part identical with second outside 19.
The size and dimension of each recess 18 is suitable on the wall 20 of the outstanding protuberance 16 that is associated and surrounding wall 20 location.Recess 18 comprises the outer gap 28 on the external margin that is positioned at chafing strip 12.Outer gap 28 has the gap 24 similar sizes with wall 20, and is positioned to alignment gap 24 in use.Recess 18 also comprises supporting member 30.Supporting member 30 is substantially rectangle, and its length is similar to the only about half of of the length of interior zone 22 and width that width is interior zone 22.In use, the supporting member 30 contiguous second inboard 21b are arranged in interior zone 22, and are positioned at the outside in the zone of aiming at gap 24 of interior zone 22.Supporting member 30 comprises in use first area supported 32 towards flange 26 orientations.Supporting member 30 has the sidewall of the shape and the second inboard 21b complementation.Supporting member 30 stretches out from the base portion of recess 18.
Coupling assembling 10 also comprises wedge lock member 48.Locking member 48 can be found out in 7 (c) best at Fig. 7 (a).
Thereby the size of locking member 48 makes lock portion 50 long enoughs extend in tapered gap 44.The angle of the wedge of lock portion 50 is similar to the angle of tapered gap 44, thereby when lock portion 50 is inserted into tapered gap 44, lock portion 50 will engage first and second area supporteds 32,42 simultaneously.
Locking member 48 and form are that the drive unit of cap screw 60 is associated.Cap screw 60 has the axle that is arranged through central hole 58.This has the enlarged 64 of contiguous termination, and away from narrow, the male thread portion 66 of termination.This enlarged 64 is arranged to be received in the retaining ring 68, and retaining ring 68 in use is arranged in depression 54.Male thread portion 66 is arranged to be bonded on screw and receives in the hole 46.Retaining ring 38 also can be alternatively have screw thread so that engage enlarged 64 on the surface within it, is used to realize any suitable mode that engages yet can utilize.
In use, engagement member 34 is arranged in interior zone 22, and wherein keyhole 40 is around protuberance 26.This is shown in the Figure 4 and 5.Chafing strip 12 reduces towards excavator bucket 14 then makes outstanding protuberance 16 be arranged in recess 18.Be appreciated that chafing strip should be sent on the protuberance 16 at a certain angle, and is rotated to the position then in order to make the complementary shaped sides of shoulder 23 coupling recess 18.This wherein sees the joint of shoulder 23 best shown in Fig. 6 (a) and 6 (b) in Figure 10.Reversing of chafing strip 12 forms tapered gap 44.Link the locking member 48 of cap screw 60, be introduced into then in outer gap 28 and the gap 24, be arranged in screw reception hole 46 thereby lock portion 50 is arranged in the male thread portion 66 of tapered gap 44 and cap screw 60.Therefore fastening cap screw 60 drives lock portion 50 and further enters in the tapered gap 44, and guarantees that chafing strip 12 is firmly connected to excavator bucket 14.Above process has realized removing of chafing strip by reversing.Think that significantly remodeling and modification fall within the scope of the present invention for those skilled in the art.
