Abstract
The utility model discloses a cyclone mill for processing a fan-shaped guide vane shaft head and a shaft hole. The cyclone mill comprises a boring mill, wherein one end of the body of the boring mill is provided with a main spindle box and a facing head, and the other end of the body of the boring mill is provided with a cyclone head; a rotary work table is arranged between the cyclone head and the main spindle box, and the rotary work table can move back and forth on the body; and a guide vane positioning device is arranged on the rotary work table. The cyclone mill disclosed by the utility model has the advantages of simple structure, low processing cost, stable processing quality and high accuracy.
Description
Technical field
The utility model relates to a kind of processing lathe, more particularly, relates in particular to a kind of whirling mill be used to processing fan-shaped entrance bucket shaft head and axis hole.
Background technology
In the kind of water conservancy equipment, fan-shaped stator is a strength member in the turbine gate mechanism, and this product is a kind of special-shaped workpiece, weight is large, the processing request of product is high, and axle position and the axis hole at two had higher tolerance, and processing technology is comparatively complicated.
The common practice that most processing enterprise takes is to select boring machine and lathe to cooperate processing, at first with the spindle nose of lathe processing stator, uses the axis hole of Boring machine processing stator other end again.With lathe processing entrance bucket shaft head the time, stator is in rotation status, even counterweight is arranged, certain centrifugal force is arranged also, and the spindle nose cylindricity of stator is not easy control, causes follow-uply when boring machine processing axis hole, and than timing difficulty relatively, machining accuracy is not easy control.
For above-mentioned situation, also have spindle nose and the axis hole of stator are all finished processing at boring machine, concrete operations are that the spindle nose of stator is finished fine finishining at boring machine, then with rotary table Rotate 180 degree, the axis hole of reprocessing stator.Adopt the stator of this method processing, the cylindricity of spindle nose is good, and the spindle nose at two and the axiality of axis hole be by the accuracy guarantee of lathe, when the trueness error of lathe during greater than the tolerance of stator, can cause the machining accuracy of stator unstable.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of whirling mill be used to processing fan-shaped entrance bucket shaft head and axis hole is provided, and this device structure is simple, convenient mounting and clamping, and the machining accuracy of stator is guaranteed.
For achieving the above object, whirling mill be used to processing fan-shaped entrance bucket shaft head and axis hole provided by the utility model, comprise boring machine, one of described boring machine lathe bed is equipped with main spindle box and facing head, cyclone head is equipped with in the other end, between cyclone head and main spindle box rotary table is installed, this rotary table can move around at lathe bed, at rotary table the stator positioner is installed.
Compare with existing fan-shaped stator finish machining equipment, the utlity model has following advantage:
1, high, the steady quality of machining accuracy: stator is fixed on the stator positioner, the processing of spindle nose and axis hole is that processing realizes by boring head, the cylindricity of machining position can guarantee, stator is to finish processing under a kind of static state, the centrifugal force that does not produce because of rotation, therefore machining accuracy is high, and crudy is stable;
2, simple in structure, processing cost is low: the utility model is simple in structure, is to have set up a cyclone head at common boring machine, stator only need to pass through simple clamping, proofread and correct after, can carry out fine finishining, clamping, adjust quick and conveniently, cost is low, efficient is high.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: the 1-boring machine; The 2-cyclone head; 3-stator positioner; The 4-rotary table; The 5-main spindle box; The 6-facing head.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not consist of any restriction of the present utility model.
Consult shown in Figure 1, the utility model is used for processing the whirling mill of fan-shaped entrance bucket shaft head and axis hole, comprise boring machine 1, one of described boring machine 1 lathe bed is equipped with main spindle box 5 and facing head 6, cyclone head 2 is equipped with in the other end, between cyclone head 2 and main spindle box 5 rotary table 4 is installed, and this rotary table 4 can move around at lathe bed, at rotary table 4 stator positioner 3 is installed, is used for fixing stator to be processed.
Before using the utility model processing stator, proofread and correct cyclone head 2 and the rotating accuracy of main spindle box 5 and facing head 6 and the linearity that rotary table 4 moves around with the standard school rod that processes first, until reach requirement.Then stator to be processed clamping on stator positioner 3 is good, check the correction stator with cyclone head 2 and main spindle box 5, after meeting processing conditions stator is tightened at stator positioner 3, spindle nose with facing head 6 processing stators, after spindle nose machines, with rotary table 4 Rotate 180 degree, still check with cyclone head 2 and main spindle box 5 and proofread and correct stator, then process the axis hole of stator, machine rear lower lathe.
The utility model is simple in structure, and machining accuracy is high, and the spindle nose of stator and axis hole axiality can be controlled in the 0.1mm, and cylindricity can be controlled in the 0.02mm.
