Description

A kind of rotational positioning processing turntable
Technical field
The invention belongs to nonstandard special process equipment technology fields, relate generally to a kind of rotational positioning processing turntable, mainly For step plane in existing machining center angular milling head processing bay section.
Background technology
Company undertakes certain model bay section shell of production at present, and material is aluminium alloy casting and forming, internal soundness and shape Dimension precision requirement is higher, and bay section casting structure is more complicated, be distributed in length and breadth rib frame, multiple mounting holes, boss, mouth frame and Front and back end frame etc., window is more, wall is thin, required precision high (IT7-IT8 grades), machined surface are more, because company lacks Multi-axis Machining at present Lathe, generally requires that centering is processed repeatedly by multiple working procedures such as vehicle, milling, boring, pincers, and not only heavy workload, manufacturing procedure is more, production Product process time and turnaround time are long, but also to occupy the process equipments such as a large amount of lathe, milling machine, boring machine, it is often more important that After part, which is dispersed to, to be processed on each lathe, the accumulated error of Set and Positioning increases, and processing precision of products ensures that difficulty is big.
Especially when processing bay section inner window plane and each boss face, since bay section shell is mostly taper barrel structure (also having semi-enclosed columnar structured), and window inner plane, convex table top are in relative closure space, narrow space is general Logical cutter can not be processed in place, if being processed using T-type knife, the method ability of manual grinding will also be taken by processing place not in place It completes, processing quality is difficult to ensure that production efficiency is low, can only meet the production requirement of development stage.For conical structure The processing of bay section window inner plane can only be machined on type horizontal processing machine tool, output progress is limited by sleeping oil (gas) filling device. If selecting vertical machining centre processing bay section window inner plane and boss, need to be equipped with angle head and turntable, due to vertical plus main shaft End face is to the height limitation of workbench, and in addition to meet processing bay section inner plane and boss requirement, the angle head of apolegamy is longer, makes Bay section and the useful space of turntable become to be extremely limited, if selection standard when the bay section window inner plane and boss of conical structure Omnipotent revolving platform, whole height is higher, and the lowermost end of angle head will interfere with bay section upper surface, cannot be satisfied bay section vertical Processed on formula machining center, if select the manual turntable of common standard, due to the manual turntable table top size of common standard and height at Proportional relation, i.e. table top are bigger, and height is higher, select the table top that can meet bay section installation, height is higher, and turntable cannot Flip angle cannot equally meet bay section and be processed in vertical machining centre.Correspondingly, related field is more perfect there is an urgent need for finding Solution, to meet such bay section in the needs of being processed in vertical machining centre.
