Description
Technical field
The utility model belongs to engineering machinery accessory field, is particularly useful for excavator, relates to a kind of novel fulcrum be applied in thrust wheel of digging machine.
Background technique
Engineering machinery needs to apply to the component such as a large amount of accessories, fastening piece, link in the process of assembling production, these component can provide safeguard for the usability of engineering machinery and Safety performance, therefore to these component, strict quality requirement will be proposed, especially engineering machinery accessory, they are not only wanted, and intensity is high, precision good, size is suitable, and also high request is had on material is selected, under safing prerequisite, suitably reduce own wt in addition also can reduce the power consumption that engineering machinery produces in operation.
At present, in the manufacturing of the component such as engineering machinery accessory, fastening piece, link, the many disunities of the material that a lot of producer adopts, so just cause its intensity and quality uneven; In addition, all relatively backward in the profile design of the component such as engineering machinery accessory, fastening piece, link, structure optimization combination and processing technology at present, can not meet the demand of the modernization in market, technicalization and hommization.
Summary of the invention
In order to solve, material disunity, intensity and quality existing for existing engineering machinery accessory is uneven, shape and the single problem of textural association, the utility model provides a kind of novel fulcrum be applied in thrust wheel of digging machine, and it has novel structure, profile is more regular, textural association is more scientific, technique is more advanced, material specification, intensity are high, quality is more stable, the feature of more durable, longer service life.
In order to achieve the above object, the utility model is achieved by following technical solution: a kind of novel fulcrum be applied in thrust wheel of digging machine, it is characterized in that, one side of fulcrum body outer side wall offers keyway, the middle part of fulcrum body outer side wall is provided with the positioning block of a circle protrusion, positioning block sidewall offers multiple pin-and-hole one, the inside of fulcrum body is provided with horizontal keyhole, the ingress of horizontal keyhole is fastened with bolt, the outer side wall of fulcrum body is also provided with multiple pin-and-hole two, pin-and-hole two is connected with horizontal keyhole, the left and right sides of fulcrum body outer side wall offers a circle sealed groove respectively.
This physical efficiency of fulcrum realizes being connected in series with a wheel body, and the left and right two ends of fulcrum is then in order to be connected in series side cover.
The beneficial effects of the utility model are, it has novel structure, profile is more regular, textural association is more scientific, technique is more advanced, material specification, intensity are high, quality is more stable, the feature of more durable, longer service life.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model Integral combined structure explosion views.
