Abstract
The utility model overcomes the shortcomings of the prior art, provide a kind of structure that can solve RV reductor cast-internal shrinkage porosites, software is poured into a mould with reference to casting process simulation, with the flexible characteristic adjustable, flexible in size is variable in fin position, solve the problems, such as cast-internal shrinkage porosite, substantially increase casting yield；In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of structure that can solve RV reductor cast-internal shrinkage porosites, including casting body, rising head and fin, the casting body is in convex shape, and major part is upward, upper side of the rising head positioned at casting body, a fin is vertically arranged with the upper surface of the casting body, the fin is rectangular parallelepiped structure, and the fin is vertically arranged on casting body；The utility model can be widely applied to casting field.
Description
Technical field
A kind of structure that can solve RV reductor cast-internal shrinkage porosites of the utility model, belongs to casting technique field.
Background technology
RV decelerators are made up of cycloidal-pin wheel and planet stent, because its small volume, anti-impact force is strong, positioning precision is high,
Many advantages, such as speed reducing ratio is big, it is widely used in the fields such as industrial robot, medical treatment, satellite receiving system.Solve RV to slow down
Machine cast-internal shrinkage porosite is foundry enterprise one of existing problem always.
Utility model content
The utility model overcomes the shortcomings of the prior art, there is provided one kind can solve the contracting of RV reductors cast-internal
The structure of pine, software is poured into a mould with reference to casting process simulation, with the flexible characteristic adjustable, flexible in size is variable in fin position, solved
Cast-internal shrinkage porosite problem, substantially increases casting yield.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：One kind can solve the casting of RV reductors
The structure of part internal porosity, including casting body, rising head and fin, the casting body is in convex shape, and major part is upward,
The rising head is located at the upper side of casting body, and a fin, institute are vertically arranged with the upper surface of the casting body
It is rectangular parallelepiped structure to state fin, and the fin is vertically arranged on casting body.
It is described to cast body, rising head and fin point-blank, and fin pitch casting body central axis
Distance be no more than 5mm.
The height that the fin is is not less than 42mm.
The utility model has an advantageous effect in that compared with prior art：The cast of the utility model combination casting process simulation is soft
Part, with the flexible characteristic adjustable, flexible in size is variable in fin position, solve the problems, such as cast-internal shrinkage porosite, substantially increase
Casting yield.The utility model is applied on the multiple serial output planetary framves of RV reductors, input planet carrier, Nian Chuanxiao
More than 300,000 yuan of benefit.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure：1 it is casting body, 2 be rising head, 3 is fin.
Embodiment
As shown in figure 1, a kind of structure that can solve RV reductor cast-internal shrinkage porosites of the utility model, including casting body
1st, rising head 2 and fin 3, the casting body 1 is in convex shape, and major part is upward, and the rising head 2 is positioned at casting body 1
Upper side, it is described casting body 1 upper surface on be vertically arranged with a fin 3, the fin 3 is cuboid knot
Structure, and the fin 3 is vertically arranged on casting body 1.
It is described to cast body 1, rising head 2 and fin 3 point-blank, and the fin 3 is away from casting body 1 center
The distance of axis is no more than 5mm.
The height that the fin 3 is is not less than 42mm.
The utility model combination casting process simulation pour into a mould software, with fin position flexibly it is adjustable, flexible in size is variable
Characteristic, solve the problems, such as cast-internal shrinkage porosite, substantially increase casting yield.The utility model is applied multiple in RV reductors
The output planetary frame of series, input on planet carrier, more than 300,000 yuan of annual benefit.
The position of fin can flexibly be set in the utility model, and technique fin generally is moved into 5mm to cast gate direction,
And fin is increased into 42mm by original 35mm.It can reach last solution and cut open cast-internal zero defect.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in those of ordinary skill in the art's possessed knowledge, the utility model aims can also not departed from
On the premise of various changes can be made.
