The adjustable blade top centre device comprises a centre seat and a centre, and is characterized by further comprising a base, a transition plate and a centre moving block, wherein the transition plate is installed on the base in a manner of transversally moving; the centre seat is installed on the transition plate in a manner of longitudinally moving; the centre is installed in the centre moving block through a centre bolt; a vertical slide groove is formed in the centre seat; and the centre moving block is installed in the vertical slide groove and capable of driving the centre to move up and down along the vertical direction of the slide groove.
Description
Technical field
The present invention relates to the processing tool field of turbine blade, be specially the adjustable leaf top Finial device of Turbine with Long Blades.
Background technology
Turbine with Long Blades to typically refer in turbomachinery length more than the blade of 900mm, the middle part of blade, often with damping boss, is characterized in that boss is with fine down to blade root position rigidity, generally can not produce distortion, and more than boss very poor to leaf top bit rigidity, be out of shape often very large.
The process of Turbine with Long Blades is, makes a call to two centre bores at the blade root position of blade forging blank, and leaf top bit makes a call to a centre bore, by three centre bore location of blade blank, machining blade profile, then square chest pre-determined bit is carried out to blade profile, by square chest location processing blade root.Due to boss above position poor rigidity, thus the distortion of this partial blade profile is very large, after causing blade profile to machine, original blade center line position has been departed from the position of leaf top centre bore, and because distortion is uncontrollable, the deviation value of every sheet blade and blade top centre bore is different, if re-use original forging blank Shang Yeding center, just be equivalent to blade slant setting in the axial direction, this is unallowed in turbine blade processing.Existing Ye Ding center holding device as shown in Figure 1, its position of top 10 is except producing axial displacement to hold out against the adjustment that leaf top centre bore cannot carry out other directions again, therefore in order to ensure the clamping position of blade, leaf top centre bore can only be beaten again, this just need first by beat straight pin and weld by vexed for original centre bore fall, then go up drill jig and beat again centre bore, the position in inspection center hole again, if do not met the demands, also need again to beat again centre bore, waste time and energy very much.
Summary of the invention
For the problems referred to above, the adjustable leaf top Finial device of Turbine with Long Blades of the present invention, it can solve the problem that directly cannot hold out against leaf top centre bore existing leaf top Finial device causes the central hole location skew of leaf top because of Turbine with Long Blades machining deformation after.
Its technical scheme is such, it comprises dead head and top, it is characterized in that: it also comprises base, rebound and centre work motion block, described rebound can be installed on described base transverse shifting, described dead head is installed on described rebound with longitudinal movement, describedly toply be installed in described centre work motion block by top bolt, described dead head offers vertical chute, and described centre work motion block to be installed in described vertical chute and can to drive described toply vertically to move up and down along described chute together.
Further, the open top of the vertical chute on described dead head, described dead head is provided with cover plate, the open top of vertical chute described in described cover closure, described centre work motion block has top T shape groove, on described cover plate, screw thread is provided with vertical adjustment bolt and described vertical adjustment bolt vertically runs through described cover plate, and the bottom of described vertical adjustment bolt is flush-mounted in described top T shape groove.
Further, the both sides cell wall of described vertical chute has the keyway vertically extended, the both sides of described centre work motion block are provided with convex key, and described convex key cooperation is installed in described keyway.
Further, on a laterally sidewall of described dead head, screw thread is provided with holding screw, and described holding screw holds out against described centre work motion block after running through described sidewall.
Further, described rebound end face has longitudinally T-slot and longitudinal keyway, the bottom surface of described dead head is provided with dead head positioning key, described dead head positioning key coordinates and to be installed in described longitudinal keyway and bottom described dead head, longitudinal both sides are connected and installed on described rebound respectively by the first T-slot bolt, the first band shoulder hex nut, and the bottom of described first T-slot bolt is flush-mounted in described longitudinal T-slot.
Further, described base top surface has horizontal T-slot and top cross keyway, described rebound bottom surface is provided with rebound positioning key, described rebound positioning key coordinates and to be installed in described horizontal keyway and described rebound both lateral sides is connected and installed on described base respectively by the second T-slot bolt, the second band shoulder nut, and the bottom of described second T-slot bolt is flush-mounted in described horizontal T-slot.
Further, the longitudinal evagination of described base has horizontal zero line on the end face of described rebound, in horizontal center position mark, and longitudinal side of described rebound is marked with the horizontal graduation mark corresponding with described horizontal zero line.
Further, the outer surface that described dead head is positioned at described vertical chute is marked with vertical zero line and the vertical graduation mark corresponding with described vertical zero line.
The beneficial effect of the present invention's adjustable leaf top Finial device is: it is by can the vertically centre work motion block that slides up and down of chute by top being installed on, dead head is installed on rebound with longitudinal movement, it is top vertically to realize that rebound can be installed on base transverse shifting, laterally, position adjustments in longitudinal direction, thus reach top can produce because of the distortion of blade with the leaf top centre bore of Turbine with Long Blades central hole location skew and carry out adaptability adjustment, therefore it does not need picture to be held out against by top because deformable blade occurs again to drill through centre bore after position offsets at leaf top centre bore again in the past, thus it is simple to operate, blade Set and Positioning is reliable, greatly can improve blade clamping efficiency.
