Description

Large-scale seat ring special plane technological method for processing
Technical field:
The invention discloses the process of a kind of large-sized water turbine field ring special plane equipment processing.
Background technology:
Seat ring is the important flow passage components of the hydraulic turbine, is also the main stressed member imbedded in parts.Large-sized water turbine field ring many employings splitted structure, processes at large-scale vertical lathe be generally combined into full circle in factory after.
Large-scale seat ring, when capacity of equipment allows, adopts general vertical Vehicle Processing more.Seat ring vertical lathe workbench forms full circle, and turnery processing is carried out in the rotation with vertical lathe workbench.After vertical Vehicle Processing, split into distinguish, processing screw hole on boring machine.Therefore the processing of whole seat ring needs to complete with Li Che and boring machine two complete equipment.
When seat ring size, weight are larger, common vertical car method processing is adopted to need to be equipped with high-mechanic, vertical vehicle device that processing tactical diameter is large.Part manufactory is limited to the reason such as place, capacity of equipment, does not possess such processing conditions, cannot implement.
Summary of the invention:
The object of the invention is to disclose the movable special plane technological method for processing of a kind of large-sized water turbine field ring, the workpiece proposing a kind of uniqueness maintains static, the special plane equipment of detachable movement carries out disposable dress pressure to large-sized water turbine field ring, the process of comprehensive processing, reduce place demand, under the prerequisite of ensuring the quality of products, improve working (machining) efficiency.Technical scheme of the present invention is: a kind of large-scale seat ring special plane technological method for processing, this process comprises the steps: that (1) adopts movable numerical control seat ring special machine tool, and its equipment body part comprises workbench [3], column [1], crossbeam [2], knife rest [7];
(2) rotary table of equipment is installed on mounting plate, and workbench uses adjustable sizing block [4] leveling on mounting plate;
(3) hang distinguish seat ring to machine tooling stroke range height, distinguish seat ring [5] is formed full circle on supporting by frock on square chest [6];
(4) reconditioner bed apparatus, by the upper existing benchmark adjustment of seat ring [5], centering, ensures that equipment is concentric with seat ring;
(5) hanging device column [1] and crossbeam [2], knife rest [7] assembly, assemble with workbench [3], adjustment precision of equipment installation;
(6) equipment workbench [3] drives column [1] and crossbeam [2] to do rotary cutting motion, and seat ring [5] dress pressure maintains static;
(7) machine tool beam band movable knife rack [7] does revolution cutting, and processing seat ring [5] plane, inner circle, then pull down tool holder [7], milling head [8] is installed, thread mill drilling joint hole, by completing above-mentioned technique content, completes each position processing of large-scale seat ring.
The present invention adopts a set of multiple functional movable numerical control seat ring special machine tool equipment, is arranged on mounting plate and processes seat ring workpiece.In the fixed situation of processing component, drive column, crossbeam and knife rest to rotate by workbench and realize turnery processing, realize boring, the Milling Process of seat ring after changing milling head, ensure that crudy.
This process method equipment centering, easy to process, efficiency is high.Once mounting equipment, comprehensive car, Milling Machining seat ring, be specially adapted to large-sized water turbine field ring structure.
The present invention can fully ensure seat ring crudy, utilizes movable equipment replacement large-scale vertical lathe to process, and final guarantee machined surface surface roughness is not less than Ra3.2, and flatness is less than 0.15mm.
This process has been broken away from traditional handicraft and has been adopted large-scale general to found vehicle device processing mode, and require low to Equipment Foundations, place adjusts flexibly.
Compared with traditional handicraft, adopt the movable equipment of car, boring one, once mounting and all being machined by seat ring, working (machining) efficiency is high, quality good, without secondary centering dress pressure workpiece.Moved flexibly by equipment, manufacturing field is made full use of.
Compared with common process, this is processed as the fixed processing mode of workpiece, and equipment rotates, and such gross weight of equipment amount alleviates, and cost reduces.Because workpiece maintains static, make that crudy is reliable, safety.
This art inventions has been applied to the processing of plentiful reconstruction stay ring, and this seat ring maximum gauge Ф 16570mm, ensure that the required precision of machined surface surface roughness Ra 3.2, flatness 0.15mm; The application of this special plane equipment realizes the original seat ring process equipment upgrading of my company, meets the nervous demand of production site.
