Abstract
The utility model announces a kind of cylinder bottom part engraved structure, belongs to hydraulic cylinder technical field.A kind of cylinder bottom part engraved structure, including cylinder bottom ontology, multiple arcs slot is offered on the cylinder bottom ontology inner face, and multiple arc grooves are uniformly distributed around cylinder bottom body central.The cylinder bottom ontology inner face center is provided with circular trough, and the center of circle of the arc groove is overlapped with the center of circle of circular trough.The utility model is to cylinder bottom end part hollow out, while meeting intensity, preferably meets mechanical lightweight requirements, component itself loss of weight about 10% ~ 15% is opposite using for higher intensity alloy material, greatly reduces cost.
Description
Technical field
The utility model relates to hydraulic cylinder technical field, specifically a kind of cylinder bottom part engraved structure.
Background technique
Part engineering machinery hydraulic cylinder is quite stringent to lightweight requirements, especially the arm support similar to concrete mixer class
Hydraulic cylinder product, lightweight requirements are very harsh.It is matched in high-strength material, high-strength aluminum alloy application and safety coefficient
In the case where weight can not being further decreased, it is imperative to find other effective methods.Distribution of weight is more concentrated
Cylinder bottom, earrings type component, since its stress is frequent, the light-weight design that enterprise inside the circle did not did at this position.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of cylinder bottom part engraved structure.
The utility model is achieved through the following technical solutions: a kind of cylinder bottom part engraved structure, including cylinder bottom ontology, described
Multiple arcs slot is offered on cylinder bottom ontology inner face, multiple arc grooves are uniformly distributed around cylinder bottom body central.
It is further: the cylinder bottom ontology inner face center is provided with circular trough, the center of circle of the arc groove and circular trough
The center of circle be overlapped.
The circular trough is a stepped groove.
There are four the arc groove is total, it is provided with opposite threaded hole in cylinder bottom ontology two sides, threaded hole is opposite with inside
Arc groove connection.
Cylinder bottom ontology outer end is provided with hinge hole.
Compared with prior art, the utility model has the beneficial effects that meeting the same of intensity to cylinder bottom end part hollow out
When, preferably meet mechanical lightweight requirements, component itself loss of weight about 10% ~ 15%, it is opposite using higher intensity alloy material come
It says, greatly reduces cost.
Detailed description of the invention
Fig. 1 is the utility model assembling schematic diagram；
Fig. 2 is the utility model main view；
Fig. 3 is the utility model right view；
In figure: 1, cylinder bottom ontology；2, arc groove；3, circular trough；4, threaded hole；5, hinge hole.
Specific embodiment
It is a specific embodiment of the utility model below, the utility model is described further now in conjunction with attached drawing.
As shown in Figure 1 to Figure 3, a kind of cylinder bottom part engraved structure opens up multiple arcs slot 2 on 1 inner face of cylinder bottom ontology,
A circular trough 3 is also opened up at 1 inner face center of cylinder bottom ontology, multiple arcs slot 2 is uniformly distributed around circular trough 3, the center of circle of arc groove 2
It is overlapped with the center of circle of circular trough 3.
Circular trough 3 is a second order stepped groove, a minor diameter deep gouge of major diameter deep gouge and center including portion.
2 numbers of arc groove are preferably even number, are preferably four in the present embodiment.It is provided in 1 two sides of cylinder bottom ontology opposite
Threaded hole 4, the arc groove 2 opposite with inside of threaded hole 4 are connected to.
1 outer end of cylinder bottom ontology is provided with hinge hole 5.
This is mainly used in hydraulic cylinder, including cylinder bottom, earrings etc. using confidence.As shown in Figure 1, in hydraulic cylinder left part
Cylinder bottom part inwards, be hydraulic cylinder hinge force part, and be also weight centrostigma, the present embodiment passes through in cylinder bottom
It, can be on the basis of meeting matrix strength and rigidity, to greatest extent towards one end inside cylinder barrel using local engraved structure
Mitigate weight.Product exemplar patterning process after actual condition verification experimental verification in the present embodiment, before meeting reliability requirement
It puts, realizes lightweight, components itself loss of weight about 10% ~ 15%.
