Abstract
The invention relates to a numerical control machining fixture device for an impulse water turbine runner. A base plate is a square steel plate and can directly fix a whole set of clamping fixture on a workbench through a pressure plate; supporting rib plates and beam-type rib plates are welded on the base plate in a staggered mode and form relations of triangular support; a center positioning disk is fixed on the supporting rib plates and connected with the supporting rib plates through lateral threads; the internal diameter of the runner forms the clearance fit with a center bushing; the runner is placed on the center positioning disk; positioning bolts pass through holes of the center positioning disk and the runner to fasten a workpiece; and positioning pins pass through positioning pin holes of the center positioning disk and the runner. The invention save the tooling cost, positions accurately and saves the installation time. The rib plates adopt the welding structure of triangular support with firmness and stability and prevent workpiece deflection caused by non-uniform stress in the process of machining.
Description
Technical field: the present invention relates to a kind of numerical control machining fixture device for impulse water turbine runner.
Technical background: both at home and abroad the structure of impulse turbine core component runner has three kinds, be respectively block cast polishing form, partly weld half machined form, forge the whole machined form in back.Casting polishing runner is more coarse, the water conservancy performance indications that are difficult to meet design requirement, cause the output of hydraulic turbine deficiency, cause unit vibration, relatively poor because of casting material mechanical performance simultaneously, there is the large tracts of land area of stress concentration at the runner root, cause stress release under the huge external force effect of high water head, cause runner root fracture (also being disconnected bucket phenomenon), disconnected bucket consequence is quite serious, the lighter causes runner to be scrapped, and weight person all damages whole unit because of the huge unbalanced moments that disconnected bucket produces.For the runner that forges the whole machined form in back, the form and position tolerance and the dimensional tolerance of the fine control unit of one side digital control processing energy, the water conservancy performance is very good, can improve workman's working condition greatly on the other hand, reduce labour intensity, of paramount importance is because load and stress that forged steel bears all are higher than cast steel far away, therefore forges the disconnected bucket phenomenon that the whole digital control processing runner in back can effectively prevent runner, prolongs the service life of unit.So the user directly requires the digital control processing of monobloc forging blank in bidding documents, the design feature of impact type waterturbine wheel be runner profile curvature change greatly, complex-shaped.Therefore the whole machining in back is made in the whole impact forging of digital control processing, needs through car, mills, the boring three process, and the complexity of processing mode has just determined the importance of runner clamp for machining design.
Goal of the invention: the objective of the invention is to disclose a kind of clamping stable, simplify mounting process, be convenient to process, be applicable to the special fixture device of multiple machine tooling runner.Technical scheme of the present invention is: a kind of numerical control machining fixture device for impulse water turbine runner, base plate is a square plate, base plate can directly be fixed on a whole set of anchor clamps on the workbench by pressing plate, bearing rib and the zigzag weld of cross beam type gusset are connected on the base plate, bearing rib becomes the gusseted relation with the cross beam type gusset, each eight, symmetrical configuration, angle at 45 between per two bearing ribs, the centralized positioning dish is fixed on the bearing rib, centralized positioning dish and bearing rib are linked together by the thread connection of side, the runner internal diameter cooperates with the centralized positioning shell clearance, and runner is placed on the centralized positioning dish, bolt is passed the hole of centralized positioning dish and runner, closing fastening workpiece, alignment pin passes the dowel hole of centralized positioning dish and runner.
The present invention has the following advantages:
1, same anchor clamps are used in multiple operation processing, save the frock cost;
2, multiple operation is installed conveniently, accurate positioning, and the position error of avoiding distinct device to adopt different localization methods to produce is saved the set-up time simultaneously;
3, gusset adopts the gusseted Welding Structure, and more stable and stronger prevents discontinuity generation workpiece deflection in the process.

5 centralized positioning dishes, 6 centralized positioning sleeve pipes
7 bolts, 8 alignment pins
9 runners
The specific embodiment:
As shown in Figure 1, base plate 2 is a square plate, can directly by pressing plate a whole set of anchor clamps be fixed on the workbench 1, and is easy for installation stable.Bearing rib 3 and 4 zigzag welds of cross beam type gusset are connected on the base plate 2.4 one-tenth gusseted relations of bearing rib 3 and cross beam type gusset, each eight, symmetrical configuration, angle at 45 between per two bearing ribs 3, this kind is firm in structure, can prevent that workpiece from deflecting because of discontinuity in process.
As shown in Figure 2, centralized positioning dish 5 is fixed on the bearing rib 3, and the thread connection by the side links together both.16 screws, dowel hole and centralized positioning sleeve pipe 6 are arranged on the centralized positioning dish 5.As shown in Figure 4,16 holes, a dowel hole are arranged also on the runner 9, runner 9 internal diameters and centralized positioning sleeve pipe 6 matched in clearance.Runner 9 is placed on the centralized positioning dish 5, and bolt 7 is passed the hole of centralized positioning dish 5 and runner 9, closing fastening workpiece, equally alignment pin 8 is passed the dowel hole of centralized positioning dish 5 and runner 9, accurate location, i.e. and installation, as shown in Figure 3.
