Technical field
The present invention relates to the processing of frame made of aluminum profiles, more particularly to ensure the clamping and processing of frame made of aluminum profiles machining accuracy
Method.
Background technology
Aluminium section bar the advantages of light weight intensity is high due to being increasingly widely applied, and aluminium section bar is made various frames and applied
In production and living, especially with television frame industry development more very, present majority DTVs, the television display screen of Web TV
Housing use frame made of aluminum profiles, dia-cutting is needed after the roughing of rectangle frame made of aluminum profiles is good, but due to the good square of roughing
Shape frame made of aluminum profiles has tolerance such as through the frame made of aluminum profiles of casting between the size between a batch of different frames, and
Existing clamping processing mode is after whole rectangle frame made of aluminum profiles is clamped and then machining, but due to different frames
Size has tolerance certainly, not of uniform size, can not so accomplish each frame can clamp completely, completely fit benchmark situation, give up
Product rate is also just of a relatively high.
The content of the invention
Present invention mainly solves technical problem be there is provided it is a kind of can not only ensure aluminium section bar television frame plus
Work precision, the clamping processing method for also ensuring that other types frame made of aluminum profiles machining accuracy.
For convenience of describing, the length of rectangle frame made of aluminum profiles is defined as Y-direction to being defined as X to, its short, and by rectangular aluminum

Point, the withdrawing of corner point, which can be careless about, to be nor affected on or is also not in connect tool marks, because follow-up machining is from angle point
Another side start feed processing）.3rd Y-direction clamping device and the first Y-direction clamping device can also merge into a Y-direction clamping
Device, but so set when its position as the second Y-direction clamping device, in midpoint from X to aluminium section bar moulding.Foregoing step
Rapid two can realize that this is conventional meanses on CNC, is not repeated to the Overall Steps of step 9 by automatically controlled mode.In step
IV C, VI the C action for being eventually adding a 4th Z-direction clamping device, ensure the clamping of Z-direction with a more step.In step V A
The Y-direction aluminium section bar moulding of second right angle is conllinear with the Y-direction aluminium section bar moulding of the first right angle in step III B, is all in fact
One Y-direction moulding of rectangle frame made of aluminum profiles, simply the mode described in different steps is different, and similar situation also has step
The X of second right angles of the X of the 3rd right angle into aluminium section bar moulding and step V B is to aluminium section bar moulding and step in VII A
The Y-direction aluminium section bar moulding of the 4th right angle in Ⅸ A and the Y-direction aluminium section bar moulding and step of the 3rd right angle in step VII B
The X of the right angle of the 4th right angle the 4th in rapid Ⅸ B is to the X of the first right angle in aluminium section bar moulding and step III A to aluminium section bar
Moulding.X in step VIII B, VI B, IV B and II B is acted when also can be different to clamping device and Y-direction clamping device, one in front and one in back
Clamping also may be used.Setting of the height of positioning datum plate less than the height of aluminium section bar moulding is to not influence the stage property of machining
Machining.
As present invention ensure that the clamping and the further improvement of processing method of frame made of aluminum profiles machining accuracy, the first X to
Length from the X of clamping device to positioning datum plate be Y-direction aluminium section bar moulding length 1/2nd；X from 2nd X to clamping device
It is 1/2nd of Y-direction aluminium section bar moulding length to the length of positioning datum plate；The Y-direction positioning datum of second Y-direction clamping device
The length of plate is X to 1/2nd of aluminium section bar moulding length.Such setting further ensure that complete patch during clamping
Benchmark is closed without clamping inaccurate situation.
The clamping force of angle clamping device is less than or equal to the critical force of rectangle frame made of aluminum profiles angular deformation；The X is filled to clamping
The clamping force put with Y-direction clamping device is less than or equal to the critical force that aluminium section bar moulding is deformed.Preferably clamping force is equal to aluminium section bar
The critical force of moulding deformation, the deformation of frame made of aluminum profiles when being so both not in clamping, while rectangle can also have been clamped closely
Frame made of aluminum profiles.
The thinking of the present invention is adapted to a variety of machining modes, for there is the different machinings of the frame of tolerance equal
Such a clamping processing mode can be used.It can slowly accumulate many in view of scrap after processing a period of time, so clamp processing follow-up
When the situation of influence benchmark occurs, typically now using seeing by the way of such as air blowing or also and be arranged to work top to possess
Groove, lower logical negative inspiratory pressure equipment by scrap suck or the groove that is blown into below work top level height in mode etc.
Deng being prior art, do not repeat.
The present invention copes with the rectangle frame made of aluminum profiles of different tolerances, and complete and benchmark of fitting completely can be clamped every time,
And be not in the defect for connecing tool marks；Setting against block coordinates the clamping mode at gradually four right angles of clamping, it is ensured that every time
Benchmark before when clamping a right angle does not influence to clamp benchmark below；What positioning datum plate length was set, which considers, also more ensures folder
Tight is accurate；Clamping force suitably chooses the deformation that ensure that frame made of aluminum profiles when being both not in clamping, while can also be close
Rectangle frame made of aluminum profiles is clamped；And the thinking of the present invention can be applicable a variety of different machining modes, popularization and application
Easily.
