Abstract
The invention discloses a kind of distortion-free processing method of thin-walled disk-like accessory, fixture is arranged on floral disc, centering fixture, fixture is provided with through hole；By clamping workpiece to be added on fixture, centering workpiece to be added；Low-melting-point metal is poured into from Folder through-holes at the inner chamber between fixture and part, it is ensured that the full inner chamber of low-melting-point metal filling；After low-melting-point metal is cooled to normal temperature, workpiece to be added is conventionally processed, workpiece is removed after machining.By the application and the design of metal fixture of low melting point technology, finally solve thin-walled parts and deform in process greatly, easily produce the knife that shakes, size is difficult to ensure the problem of card.
Description
Technical field
The present invention relates to thin-walled disk-like accessory processing technique field, it particularly relates to a kind of thin-walled disk-like accessory is preapred for an unfavorable turn of events
The processing method of shape.
Background technology
The need for social development, in aeronautical product manufacturing process, to the quality requirement more and more higher of aeronautical product,
Therefore designed capacity and manufacturing capacity is needed to be lifted, the integration degree of aerial motor spare part also more and more higher, part sets
Meter tends to entirety, light weight, accurate development, and moulding surface structure also becomes increasingly complex, traditional to Product processing requirement more and more higher
Processing method is difficult to meet new machine manufacture claim.Disk-like accessory is gradually meeting strength conditions lower wall thickness more and more thinner, and morpheme is public
Easily there is deformation and causes unqualified in process in difference more and more higher, disk-like accessory, therefore to improve thin-walled parts and adds
The qualification rate of work, it is necessary to solve the technical problem of thin-walled disk-like accessory machining deformation.For example, when aviation disc is processed, by
Part wall thickness is too thin at disc, itself poor rigidity, and part easily changing with cutting temperature and being deformed during processing.Make workpiece one
Cut while starting deformation, also easily knife is shaken in generation, prevents Part Surface Roughness, size, form and position tolerance from meeting reality on side
It is required that.
The content of the invention
In view of this, it is thin to solve it is an object of the invention to provide a kind of distortion-free processing method of thin-walled disk-like accessory
The technical problem of wall disk-like accessory machining deformation.
The present invention solves above-mentioned technical problem by the following technical programs：
A kind of distortion-free processing method of thin-walled disk-like accessory, comprises the following steps：
(1) fixture is arranged on floral disc, centering fixture, the fixture is provided with through hole；
(2) by clamping workpiece to be added on fixture, centering workpiece to be added；
(3) poured into from Folder through-holes after low-melting-point metal is melted at the inner chamber between fixture and part, it is ensured that eutectic
The metal filled full inner chamber of point；
(4) after low-melting-point metal is cooled to normal temperature, workpiece to be added is conventionally processed, work is removed after machining
Part.
The upper surface of the fixture is provided with spigot edge, and through hole is provided with fixture side, and the other end of through hole is opened in folder
On the upper surface of tool.
The through hole is " L " shape.
Aperture of the fixture on side is entrance, and aperture on an upper is outlet.
The fixture is made of refractory metal.
The refractory metal is iron, steel, copper or aluminium.
The LMP metal is lead or tin.
The beneficial effects of the present invention are：By the application and the design of metal fixture of low melting point technology, finally solve
Thin-walled parts deform greatly in process, easily produce the knife that shakes, and size is difficult to ensure the problem of card, improves converted products quality,
Improve the dimensional accuracy of manufacture product, it is ensured that part processing once submits to qualification rate, qualification rate to reach 100%, and time saving province
Power, improves operating efficiency.

Specific embodiment
For convenience it will be understood by those skilled in the art that, the present invention is done further below in conjunction with embodiment and accompanying drawing
Description.Embodiment is only for example, be not limitation of the invention, not make what is illustrated in embodiment to the invention
Step is prior art, is not described in detail herein.
Embodiment
A kind of distortion-free processing method of thin-walled disk-like accessory, (1) design fixture：As shown in figure 1, fixture is flat part,
There is a spigot edge 201 on the upper surface of fixture, parts to be processed stabilization can be conducive to being smoothed out for processing, in folder
1 through hole 202 of " L " shape is opened in tool side, and the other end of through hole is opened on the upper surface of fixture, and the aperture on side is entrance
204, aperture on an upper is outlet 203, it is ensured that after part loads fixture, outlet 203 is located at the inside cavity of part,
And near chamber central；(2) installs fixture：Then the fixture being related to is arranged on the floral disc of Digit Control Machine Tool, centering fixture；
(3) workpiece to be added is installed：By clamping workpiece to be added on fixture, centering workpiece to be added；(4) low-melting-point metal is poured into：Rotating clamp
Tool, by fixture entrance 204 upward, by the low-melting-point metal of molten state from the inner chamber that entrance 204 pours between fixture and part,
When thering is low-melting-point metal to overfill at entrance 204, it was demonstrated that low-melting-point metal is poured into and completed, treat that low-melting-point metal is sufficiently cool
To the low-melting-point metal that normal temperature, cleaning overfill；(5) workpiece is processed：It is completely processed and removes workpiece, without dismantles low-melting-point metal
The model of formation, loads onto second workpiece and continues to process, alternatively, it is also possible to heat after low-melting-point metal melts it, repeat with
Upper step carries out second work pieces process.
The fixture is made of refractory metal.
The refractory metal is iron, steel, copper or aluminium.
