Description
The present invention relates to a kind of numerical control part milling method is planted, it is related specifically to a kind of numerical control part Milling Process folder
Clamping method.
Part need to clamp on the table in part by numerical control Milling Process, and part clamped condition is unbalanced will directly to cause zero
Cutting stress is unevenly distributed in part process, causes part deformation serious；And clamped condition is unstable, will lead to part vibration
Greatly, cutter and equipment will be also damaged, and be easy to cause part to be processed quality problems in this way, and the basic size that not can guarantee part is wanted
It asks.Currently, one is use multiple general pressing plates directly to compress zero in numerical control processing there are three types of the common clamping modes of part
Part, since platen clamp structure movement is big when which Clamp blocks, human factor is larger, and pressing plate is theoretically face with part
Contact, but be often only capable of reaching line contact when practical operation, or even be many times only capable of point contact, pressing force and compaction direction are not
It can be completely secured, thus compress reliability and not can guarantee；Position when which Clamp blocks between pressing plate is not exclusively true
Fixed, the interaction force relationship between pressing plate changes with the variation operated every time, and structural impaction state is caused to lose
Weighing apparatus, the size of pressing force influence to generate uneven also with the unbalanced of pressing plate different location and compression force direction；In addition should
The pressing plate of mode needs muti-piece to combine, and adjustment is complicated, and when part outline face is irregular, the clamping point of pressing plate must be as far as possible
Close to part, lead to that special pressing plate must be used in different location.It is for second the clamping side of bolt presses false boss strong ties
Formula, i.e., setting false boss in position appropriate, false boss bolt presses, although base when which Clamp blocks on part
Originally solve the problems, such as that reliability is not high, but its false boss is mutually indepedent, interaction force relationship between false boss
It can change with the variation operated every time, cause impaction state unbalance；The size of pressing force exists also with false boss
The unbalanced and compression force direction of different location influences to generate imbalance, thus not can guarantee the equilibrium of clamped condition；In addition
The bench work amount that part removes the connecting portion of false boss after processing is completed is very big；It must be provided with specially additionally, due to which
False boss inevitably increases blank dimension, while the blank around false boss is all destroyed, and can not carry out
It recycles, blank utilization rate is lower.The third is part integrated artistic boss featheredge bridge joint clamping means, and such clamping means are wanted
Ask the first face by External Shape in the height direction not only milling in place, but also than part height depth 2mm to 5mm, part
Another side top surface and part clout be connected, finally by part connecting portion milling open.In order to control cost, the blank of part
Thickness 10mm generally thicker than part or so, one-sided thickness only has 5mm to 8mm, so in this top bridging method, part and hair
Base clout connects thinner thickness, and connection rigidity is bad, and for only having sash on one side, and another side is for the part of plane,
It is relatively good using this processing method, because another side is entirely directly contacted with tool positioning surface when processing sash, branch
Support it is more stable, so processing performance is fine, and for the two-sided part that there is sash on two sides, because part and tooling are fixed
Plane contact only has the part of surrounding rib top surface, part positioning support face very little, if rib height is different, that is for positioning
Contact surface it is just smaller, support highly unstable, it is insufficient connect rigidity when process the second face for part in this way, processes
State will be highly unstable, is easy to produce the phenomenon that playing knife broaching tool, influences the processing quality of part, and in order to guarantee that connection is rigid
Property, this scheme is in blank using above would generally be thicker, and service efficiency is not high in a thickness direction for blank, economy also not counting
It is very high.
Obviously, prior art numerical control part milling processing clamping method there is impaction states unbalance, blank utilization rate compared with
The problems such as low and machining state is unstable.
