A kind of heat-resisting alloy honeycomb part Milling Machining clamp methodTechnical field
The invention belongs to aero-engine manufacturing technology field, particularly relate to a kind of heat-resisting alloy honeycomb part Milling Machining clamp method.
Background technology
At present, existing heat-resisting alloy honeycomb part Milling Machining clamp method is: stick with glue or fix heat-resisting alloy honeycomb part by the method for vacuum suction.Gluing method operation and removal complexity, clamping poor reliability; The method cost of investment of vacuum suction is relatively large, and the part of clamping has certain limitation.
Summary of the invention
For prior art Problems existing, the invention provides a kind of operation and remove simple, that cost is low, clamping reliability is strong heat-resisting alloy honeycomb part Milling Machining clamp method.
To achieve these goals, the present invention adopts following technical scheme, and a kind of heat-resisting alloy honeycomb part Milling Machining clamp method, comprises the steps:
Step one: industrial paraffin and shot or cast iron pellets are mixed and heated to molten condition;
Step 2: be filled in the space of heat-resisting alloy honeycomb part to be processed by the mixture of the industrial paraffin and shot or cast iron pellets that are heated to molten condition, two sides equating after cooling obtains heat-resisting alloy honeycomb part blank;
Step 3: by the magnetic force platform absorption of heat-resisting alloy honeycomb part blank, Milling Machining can be carried out to it.
Being mixed with shot or cast iron pellets by industrial paraffin described in step one is with percentage by weight 1: the ratio of (0.3 ~ 1) mixes.
Beneficial effect of the present invention:
The invention solves heat-resisting alloy honeycomb part because the problem of nonmagnetic NC Milling clamping difficulty, make heat-resisting alloy honeycomb part by numerical control Milling Machining become very simple, effective; Its operation and removal are simply, cost is low, clamping reliability is strong.
Be applied in by clamp method of the present invention in the development process of aircraft of new generation or engine, the Huge value created, annual material of saving at least is worth millions of.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
A kind of heat-resisting alloy honeycomb part Milling Machining clamp method, comprises the steps:
Step one: by the shot of industrial paraffin and shot-peening or cast iron pellets with percentage by weight 1: the ratio of (0.3 ~ 1) is mixed and heated to molten condition;
Step 2: the mixture of the industrial paraffin and shot or cast iron pellets that are heated to molten condition is filled in the space 2 of heat-resisting alloy honeycomb part to be processed, two sides equating after cooling obtains heat-resisting alloy honeycomb part blank, the structure of heat-resisting alloy honeycomb part blank, as shown in Figure 3; The structure of heat-resisting alloy honeycomb part to be processed, as shown in Figure 1 and Figure 2;
Step 3: by the magnetic force platform absorption of heat-resisting alloy honeycomb part blank, namely by digital control processing, its Milling Machining is become the shape of needs.
After machining, by adding the mixture (i.e. filler) 3 of heat abstraction industrial paraffin and shot or cast iron pellets; Then clean, the heat-resisting alloy honeycomb part needed can be obtained.
