Description
Technical field
The present invention relates to the top dress in adjustable leaf top in the processing tool field of turbine blade, specially Turbine with Long Blades
Put.
Background technology
Turbine with Long Blades typically refers to the blade that length in turbomachinery exceedes 900mm, and the middle part of blade is often with resistance
Buddhist nun's boss, is characterized in below boss rigidly fine to blade root position, will not typically be deformed, and boss is with the top of up to leaf
Position rigidity is very poor, deforms often very big.
The process of Turbine with Long Blades is that two centre bores are made a call at the blade root position of blade forging blank, position at the top of leaf
A centre bore is made a call to, is positioned by three centre bores of blade blank, blade profile is processed, then blade profile progress square chest is made a reservation for
Position, passes through square chest positioning processing blade root.Because boss is with upper bit poor rigidity, thus the partial blade type facial disfigurement is very big, leads
After cause blade profile is machined, the position of leaf top centre bore has deviated from original blade center line position, and due to becoming
Shape is uncontrollable, and the deviation value of every blade and blade top centre bore is different, if reusing the leaf top on original forging blank
Center, is equivalent to blade slant setting in the axial direction, and this does not allow in turbine blade processing.Existing leaf top
Center holding device as shown in figure 1, its top 10 position leaf top centre bore is held out against except axial displacement can be produced can not be again
The regulation in other directions is carried out, therefore in order to ensure the clamping position of blade, leaf top centre bore can only be beaten again, this is accomplished by first leading to
Cross beat straight pin and welding by original centre bore it is vexed fall, then upper drill jig beats again centre bore, then inspection center hole position,
If being unsatisfactory for requiring, in addition it is also necessary to beat again centre bore again, waste time and energy very much.
The content of the invention
In view of the above-mentioned problems, the adjustable leaf top Finial device of Turbine with Long Blades of the present invention, it can solve existing leaf top top
Sharp device can not directly hold out against leaf top centre bore after causing the central hole location skew of leaf top because of Turbine with Long Blades machining deformation
Problem.
Its technical scheme is such, and it includes dead head and top, it is characterised in that：It also includes base, rebound
With top movable block, the rebound can be installed on the base transverse shifting, and the dead head is pacified with longitudinal movement
Loaded on the rebound, it is described it is top be installed on by top bolt in the top movable block, the dead head is offered
Vertical chute, the top movable block is installed in the vertical chute and can driven described top perpendicular along the chute together
To moving up and down.
Further, cover plate is installed on the open top of the vertical chute on the dead head, the dead head, it is described
The open top of vertical chute described in cover closure, the top movable block is provided with screw thread on top T-slot, the cover plate and installed
There is vertical adjustment bolt and the vertical adjustment bolt vertically runs through the cover plate, the bottom of the vertical adjustment bolt is embedded in
In in the top T-slot.
Further, vertically extending keyway, the top movable block are provided with the both sides cell wall of the vertical chute
Both sides be provided with convex key, the convex key, which coordinates, to be installed in the keyway.
Further, screw thread is provided with holding screw on the horizontal side wall of the dead head, and the holding screw runs through
The top movable block is held out against after the side wall.
Further, the transition plate top surface is provided with along longitudinal T-slot and longitudinal keyway, and the bottom surface of the dead head is set
There is dead head positioning key, the dead head positioning key, which coordinates, to be installed in longitudinal keyway and dead head bottom longitudinal direction
Both sides are connected and installed on the rebound by the first T-slot with bolt, first band shoulder hex nut respectively, the first T
Shape groove is flush-mounted in the longitudinal T-slot with the bottom of bolt.
Further, the base top surface is provided with the horizontal keyway of horizontal T-slot and top, and the rebound bottom surface is provided with
Rebound positioning key, the rebound positioning key, which coordinates, to be installed in the horizontal keyway and the rebound both lateral sides point
It is not connected and installed in by the second T-slot with bolt, the second band shoulder nut on the base, the second T-slot bolt
Bottom is flush-mounted in the horizontal T-slot.
Further, the base is longitudinally externally protruded out on the top surface of the rebound, in horizontal center position mark
There is mark in horizontal zero line, the longitudinal side of the rebound to have the corresponding horizontal graduation mark of the horizontal zero line.
Further, the dead head be located at the vertical chute an outer surface on mark have zero line and with
The corresponding vertical graduation mark of the vertical zero line.
The beneficial effect of the adjustable leaf top Finial device of the present invention is：It is by can vertically chute by top be installed on
Top movable block, the dead head slided up and down is installed on rebound, rebound and can be installed on transverse shifting with longitudinal movement
Base realizes the top position adjustments on vertical, transverse direction, longitudinal direction, thus reach it is top can with Turbine with Long Blades Ye Dingzhong
The central hole location that heart hole is produced by the deformation of blade offsets and carries out adaptability regulation, therefore it need not be as in the past in Ye Ding
Centre bore is held out against by top again because drilling through centre bore again after deformable blade generation position skew, thus its simple to operate, blade
Set and Positioning is reliable, can greatly improve blade clamping efficiency.
