Description
Technical field
This utility model is excavated in belonging to engineering machinery and mining machinery, the parts technology neck of loading operation machinery
A kind of domain, and in particular to excavator bucket teeth coupling assembly.
Background technology
Excavator is a kind of conventional engineering machinery, and it is higher or lower than the thing for holding machine side that excavator main will be excavated using bucket
Material.The Main Function of the bucket tooth on bucket is to break material, therefore when excacation is carried out, the impulsive force that bucket tooth is subject to is very
Greatly.When the material encountered is more hard, or during misoperation, bucket tooth is very easy to damaged and fractures.In the market more
Common bucket tooth component all includes bucket tooth, toothholder and pin, and toothholder is welded on bucket, and bucket tooth is fixedly connected on tooth by pin
On seat.
201210108708.X discloses a kind of excavator bucket teeth, including the toothholder with installation portion and with connecting portion
Bucket tooth, offers the pin-and-hole on same axial line, described toothholder on two connecting portion of described toothholder installation portion and bucket tooth
Installation portion be inserted between two connecting portions of bucket tooth and be connected by pin and jump ring, offer annular on described pin recessed
Groove and described jump ring is stuck in annular groove, offers counterbore, described counterbore on the pin-and-hole inner face on described bucket tooth
It is on same vertical plane with the annular groove on described pin and described jump ring is located in counterbore.The case is by bucket
The side of tooth and toothholder connecting portion opens up the pin-and-hole of an insertion, toward in pin-and-hole squeezes into pin, so that bucket tooth and toothholder are solid
It is fixed to connect.Such connected mode has two：First, be welded with bucket the distance between multiple toothholders, toothholder compared with
Little, pin is parallel with the weld part of toothholder and bucket.Therefore, when needing to change bucket tooth, need with hammer and one compared with
Long screw taps pin in the side of bucket toward horizontal direction, and it is very inconvenient to operate.The bucket tooth of centre is particularly at, is needed
First the bucket tooth of periphery is dismantled one by one, is so wasted time and energy very much, has been slowed down the work efficiency of excavator.Second, pin is not
Only it is the connection member of bucket tooth and toothholder, and is that powerful active force passes to maincenter between bucket tooth and toothholder.When bucket tooth component moment
During effect, pin is the main supporting body of stress, and this is very easy to cause pin to rupture.
201310183035.9 disclose a kind of excavator bucket teeth, including the toothholder with installation portion and with connecting portion
Bucket tooth, installation portion are inserted in connecting portion, have the installing hole one that insertion is arranged, arrange with insertion on connecting portion on installation portion
Installing hole two and installing hole three, installing hole two is coaxially disposed with installing hole three, installing hole two, three structure of installing hole one and installing hole
Into the pin-and-hole of an insertion, in pin-and-hole, be equipped with pin, the lateral wall of pin has a location division of radially protruding, installing hole two it is interior
With the gathering sill being engaged with the location division on the wall of side, the inner and positioning between installation portion and connecting portion of gathering sill
Groove UNICOM, the axial length of locating slot are slightly larger than the axial length of location division.Pin in the case is still strong between bucket tooth and toothholder
Noticeable effort passes to maincenter, pin still easy forced breakage, substantially reduces the working time of bucket tooth component, and increased makes
Use cost.
