Description
Technical field
The present invention relates to a kind of mounting structure being easy to bucket tooth replacing and preparation method.
Background technology
The most common excavator bucket teeth mounting structure is: use the rise alligator of spring of band to run through bucket tooth with toothholder also
Affixed, it is interference fit owing to rising between spring and installing hole, needs special power-equipment auxiliary to carry out the peace installation and dismantling of bucket tooth
Unloading, this process is laborious, complicated.In addition being dismounted for multiple times is relatively big to the abrasion of alligator, and the alligator life-span greatly reduces.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of mounting structure being easy to bucket tooth replacing and preparation method, overcomes existing
There is the deficiency in technology.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of mounting structure being easy to bucket tooth replacing
And preparation method, including toothholder, bucket tooth and pin, described toothholder has toothholder head, described bucket tooth has bucket tooth chamber, described
Toothholder head can stretch into described bucket tooth intracavity, and described toothholder head has the pin-and-hole running through described toothholder head two sides, described bucket tooth
On have corresponding with described pin-and-hole, and the through hole in through described bucket tooth chamber；
It is positioned on the described through hole of described bucket tooth one side and there is sleeve pipe, described sleeve pipe and described through hole coaxial line, described
Sleeve pipe is through with described through hole, and the end of described sleeve pipe is blind end, has spring in described sleeve pipe, is positioned at described bucket tooth side
Mask has U-shaped clamp and plate, the inwall of described U-shaped clamp to have U-type groove, and described plate can insert in described U-type groove, described
Through hole is positioned at described U-shaped clamp；
Described pin can pass described pin-and-hole and described through hole, one end of the most described pin-and-hole stretch in described sleeve pipe with institute
Stating spring to conflict, the other end of described pin-and-hole is conflicted with described plate, is connected with described toothholder head by described bucket tooth with this.
Further, the side of described bucket tooth has fixing screwed hole, described plate has and described fixing screwed hole pair
The fixed block answered, by the fixing bolt through described fixing hole and described fixed bolt hole between described plate and described bucket tooth
Fixing.
The present invention has the advantage that with good effect: owing to using technique scheme, easy accessibility, when changing bucket tooth
Little to the degree of wear of alligator, substantially prolongs the service life of alligator.

Detailed description of the invention
As shown in Figure 1, 2, the present invention provide a kind of be easy to bucket tooth change mounting structure and preparation method, including toothholder 1,
Bucket tooth 4 and pin 8, toothholder 1 has toothholder head 2, and bucket tooth 4 has bucket tooth chamber 5, and toothholder head 2 can stretch in bucket tooth chamber 5, tooth
On seat 2, there is the pin-and-hole 3 running through toothholder head 2 two sides, bucket tooth 4 has corresponding with pin-and-hole 3, and the leading to of through bucket tooth chamber 5
Hole 6；
Being positioned on the through hole 6 of bucket tooth 4 one side and have sleeve pipe 7, sleeve pipe 7 and through hole 6 coaxial line, sleeve pipe 7 passes through with through hole 6
Logical, the end of sleeve pipe 7 is blind end, has spring (not shown) in sleeve pipe 7, is positioned at bucket tooth 4 one side and has U-shaped clamp 9
With plate 10, the inwall of U-shaped clamp 9 has U-type groove, and plate 10 can insert in U-type groove, and through hole 6 is positioned at U-shaped clamp 9；
Pin 8 can pass pin-and-hole 3 and through hole 6, conflicts with spring during now sleeve pipe 7 is stretched in one end of pin-and-hole 3, pin-and-hole 3
The other end is conflicted with plate 10, is connected with toothholder head 2 by bucket tooth 4 with this.
During use, toothholder head 2 is stretched in bucket tooth chamber 5, by incoming for pin 8 pin-and-hole 3 and through hole 6, now one end of pin 8
Conflicting with spring, the other end stretches out outside the through hole 6 being positioned in U-shaped clamp 9, the part that pin 8 stretches out is pushed away in people's through hole 6, will
Plate 10 inserts in U-type groove, makes the other end of pin 8 conflict with plate 10, with this, pin 8 is fixed on through hole 6 and pin-and-hole 3
In.The mounting structure of this bucket tooth need not to realize fast assembling-disassembling by special tool(s), makes bucket tooth change convenient, sells during dismounting
The abrasion of post 8 is little, adds the access times of pin 8.
The side of bucket tooth 4 has fixing screwed hole 12, and plate 10 has the fixed block corresponding with fixing screwed hole 12, inserts
By fixing through the fixing bolt of fixing hole 11 and fixed bolt hole between plate 10 and bucket tooth 4.
Above embodiments of the invention are described in detail, but described content have been only presently preferred embodiments of the present invention,
It is not to be regarded as the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement etc.,
Within all should still belonging to the patent covering scope of the present invention.
