Description
Technical field
The invention belongs to aviation part field of machining, and in particular to a kind of annular flame tube floating wall tile stud adds
Work fraise jig and localization method, being also applied for other industries has the processing of similar structures part.
Background technology
Floating wall tile is the interior heat shield on the annular flame tube of new aeroengine combustor buring room, is made on a burner inner liner
With more than 100 a floating wall tiles, floating wall tile is sticked on burner inner liner inner flow passage wall surface, passes through the stud on tile and fire
Flame cylinder inside and outside wall is connected.Stud, stud to be cast as in the normal direction of curved surface each point with tile there are five bands on one tile
Integrally, the screw thread on stud is formed using machining.Process stud screw thread, it is necessary to by the center line and machine of each stud
Bed major axes orientation is consistent, and it needs to be determined that goes out the center of each stud.
Since tile is curved surface sheet body, stud is distributed in the normal direction of curved surface each point, and one-time positioning clamping can not possibly be same
When ensure five studs direction it is consistent with machine tool chief axis direction.On the other hand, since molten error influences, several spiral shells on tile
Mutual alignment between stake is there are error, and the error of stud to tile peripheral distance is also larger, it is impossible to by theoretical size and angle
It adjusts to process all studs.It can only determine that the direction of each stud and position are processed respectively, such as Fig. 1, shown in 2.
Tradition determines that the direction of each stud and position and speed are too slow by the method for centering, it is impossible to adapt to the need of production
It will.And the direction and position of each stud are determined by fixture positioning, because stud is short and small, and one end is connected with curved surface, located space
It is too small.Stud should be processed, is positioned again using stud, how to avoid the interference of locating piece and cutter is that design fixture faces
Matter of utmost importance.
Since there are many tile quantity of separate unit burner inner liner, and there are multiple studs again on each tile, using positioning one
The processing method of one, production efficiency are influenced very big by positioning and clamping speed, and fixture design will solve reliable location
Problem, it is often more important that also to solve the speed issue of positioning and clamping.
The content of the invention
It is an object of the invention to it is middle for the above-mentioned prior art the problem of, a kind of annular flame tube floating wall tile is provided
Stud processing milling machine fixture and localization method, to multiple and different direction in space studs on tile can be accurately positioned and quickly
Positioning, so as to fulfill the digital control processing of tile stud, to improve production efficiency.
To achieve these goals, the present invention is used for the fraise jig of annular flame tube floating wall tile stud digital control processing
The technical solution used for:Including the linear slide plate being mounted on by slideway in clamp base, rotation is provided on linear slide plate
Pedestal, the rotating base has the surface of revolution concentric with annular flame tube center line, on the surface of revolution of rotating base
Equipped with the rotary slider that can be bonded surface of revolution and be slided, orthogonal X is equipped with above rotary slider to V-block and Y
To V-block, two V-blocks are connected respectively by hinged pair with V-block pillar, and hinge hole is bar hole, and V-block pillar is fixed
In clamp base;Tile with stud is mounted on rotary slider, X is carried out to positioning to stud by Y-direction V-block,
Y-direction positioning is carried out to stud to V-block by X.
The rotating base is equipped with rotary slider side shield in surface of revolution both sides, is equipped on rotary slider side shield
The star handle for rotary slider positioning is connected with rotary slider.
The L-shaped handle for being capable of the positioning of compressing fixture pedestal is installed on the linear slide plate.
The rotary slider is equipped with multiple and can be unloaded together with tile from rotating base.
The regulation handle that V-block is driven to be moved back and forth along hinge hole is mounted on two V-blocks.
The present invention is used for positioning of the fraise jig of annular flame tube floating wall tile stud digital control processing to tile stud
Method comprises the following steps:Tile with stud is mounted on rotary slider, passes through rotary slider returning in rotating base
Turn curved surface to rotate in a circumferential direction movement, stud is made to be adjusted to the peak of surface of revolution;X is carried out to stud by Y-direction V-block to calmly
Behind position, the position of rotary slider is locked;By X after V-block carries out Y-direction positioning to stud, the position of linear slide plate is locked.
Compared with prior art, the present invention has following advantageous effect:Due to fixture first have to realize function be by
The center line of stud to be processed navigates to the direction parallel with machine tool chief axis, and three-axis machining center machine tool main shaft hangs down with workbench
Directly, so stud center line is navigated to and table vertical.And stud is adjusted to table vertical there are two ring
Section:First, stud is adjusted to the peak of surface of revolution;Second is that tile is rotated into an angle in the vertical section of peak.
Since tile curved surface is a curved surface concentric with annular flame tube center line, so in circumferencial direction, by around annular flame
The rotation of cylinder center line just can will be adjusted to curved surface peak for processing stud.The present invention devises a rotation bottom on fixture
Seat, devises a surface of revolution concentric with annular flame tube center line on the base, in addition devises a rotation and slides
Block, the lower surface camber of sliding block is one section of cylindrical surface, is engaged with the surface of revolution of rotating base, and can against returning for rotating base
Turn curved surface circumferentially to slide.The top-surface camber of rotary slider is consistent with tile medial type face, for supporting tile.So slided by rotating
Stud can be just adjusted to the peak of rotating base surface of revolution by the movement that rotates in a circumferential direction of block.The center line and tile of stud
There are an intersection point, studs in inner mold face to be located at the normal direction of the point, the tangent line of busbar and annular flame tube center line at the point
There are an angle β, stud is adjusted to and table vertical, seeks to the tangent line being adjusted to parallel with workbench.
On fixture, by the way that in a longitudinally adjusted angle beta, the center line of rotating base surface of revolution is achieved that stud in vertical section
With table vertical.In addition, second function being realized of fixture is exactly to position the central point of stud, pass through two vertical direction
V-block stud is navigated into fixed point o.Since stud is short and small, in order to avoid interference, the V-block of both direction positions respectively;
It is positioned respectively to realize, two V-blocks are all connected by hinged pair with V-block pillar, and when positioning is transferred to be contacted with stud, calmly
It is produced behind position and gets out of the way stud, so as to Tool in Cutting.In order to eliminate the interference of V-type face and stud when V-block is transferred to and produces, therefore
V-block hinge hole is designed to bar hole, V-block is made to have certain back-and-forth motion amount.The present invention can on tile it is multiple not
Isospace direction stud be accurately positioned and quickly positioned, and so as to fulfill the digital control processing of tile stud, and then improves production
Efficiency.
Further, rotary slider of the present invention is equipped with multiple and can be unloaded together with tile from rotating base, in lathe
During work, next tile is mounted on next rotary slider in advance outside machine, after processing a tile, by tile
It is integrally unloaded together with rotary slider, changes another rotary slider that tile is housed, shorten positioning, the shutdown of clamping parts consumption
Time.
