Abstract
A kind of processing unit (plant) of tilting pad eccentric inner hole includes positioning arc surface M, datum hole H, centering datum level P and two location hole W for fixation clip on pedestal；The circle center distance that the pitch-row between arc surface M and datum hole H is the inside and outside circle of tilting pad is wherein positioned, the centre bore of arc surface M is vertical with positive datum level P with the line of datum hole H；Fixation clip is fastened on pedestal, forms combined integrated structure, and movable pressing board is connected to force on pedestal and is locked；By positioning datum of the positioning arc surface M as tile fragment outer circle on its pedestal, and limiting locking is carried out with fixation clip and movable pressing board；After processing unit (plant) centering is fixed, it is no longer necessary to carry out secondary centering to tilting pad, just be effective to ensure that the clamping position and eccentricity of tile fragment, clamping is simple, convenient for directly measuring, effectively improves the quality and efficiency of tilting pad.
Description
Technical field
The utility model relates to technical field of bearing processing, in particular to the processing of a kind of tilting pad eccentric inner hole fills
It sets.
Background technique
Tilting-pad bearing is mainly used in the high speed light loadings equipment such as turbine and compressor.Generally by 3~5 or more
Arc tile fragment composition, tile fragment can freely swing with the direction of rotation of axis and the difference of bearing load, be formed around axle journal
Multiple oil film wedges.Each oil film pressure always points to center, stability with higher.When work, by the fluid of lubricating oil film
The effect of dynamic pressure forms bearing oil film wedge between tile fragment bore area and journal surface, keeps surface both completely isolated, to subtract
The friction, capability of small bearing.Tilting pad is structurally characterized in that inner hole and outer ring at diplocardia, can make tile fragment suitable around axial fulcrum
Journal motion direction is swung, to meet the movement load requirement of axis.
It is all the arc section with certain angle, and design accuracy compares due to the outer circle and inner hole decentraction of tilting pad
Height, therefore, the structure of one side tilting pad creates its outer circle and inner hole is unable to clamped one time completion and is on the other hand adding
It also will appear in work and measurement and be difficult to the problem of controlling.Usual situation is considering the influence of the factors such as clamping, processing and materials variances
In the case where, the principle of first processing excircles reprocessing inner hole should be followed.After the completion of Excircle machining, next how with outer circle to be
Benchmark how to control inner hole processing and measurement be the process key technology, in this way, design specialized tooling complete inner hole plus
Work and measurement just become inevitable.
Summary of the invention
In order to overcome the defects of the prior art described above, the purpose of this utility model is to provide in a kind of tilting pad bias
The processing unit (plant) in hole has the spy that clamping is quick, measures conveniently and tilting pad inner eccentric holes position and distance can be effectively ensured
Point solves the problems, such as the processing of hardly possible present in existing production technology and difficult measurement.
In order to achieve the above object, technical solution used by the utility model is：
A kind of processing unit (plant) of tilting pad eccentric inner hole, including pedestal 1 include positioning arc surface M, datum hole on pedestal
H, centering datum level P and two location hole W for fixation clip 2；Wherein position the hole between arc surface M and datum hole H
Circle center distance away from the as inside and outside circle of tilting pad 4, the centre bore of arc surface M and the line of datum hole H hang down with positive datum level P
Directly；Fixation clip 2 is fastened on pedestal 1 by location hole W, positioning pin 5 and A hexagon socket cap head screw 6, is formed combined integrated
Structure, movable pressing board 3 are connected on pedestal 1 by B hexagon socket cap head screw 7, and force is locked.
The utility model has the beneficial effects that：Pass through positioning base of the positioning arc surface M as tile fragment outer circle on its pedestal
Standard, and limiting locking is carried out with fixation clip 2 and movable pressing board 3.After processing unit (plant) centering is fixed, it is no longer necessary to tilting bush
Block carries out secondary centering, is just effective to ensure that the clamping position and eccentricity of tile fragment, and clamping is simple, convenient for directly measuring, has
Improve to effect the quality and efficiency of tilting pad.
Detailed description of the invention
Fig. 1 is general assembly drawing of the utility model under machining state.
Fig. 2 is 2 part drawing of fixation clip of the utility model.
Fig. 3 is 3 part drawing of movable pressing board provided by the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
It as shown in Figure 1 and Figure 2, is a kind of in the tilting pad bias under vertical boring-milling center equipment machining state
The processing unit (plant) in hole, base body 1, a kind of processing unit (plant) of tilting pad eccentric inner hole, including pedestal 1 include fixed on pedestal
Circle of position cambered surface M, datum hole H, centering datum level P and two location hole W for fixation clip 2；Wherein positioning arc surface M and
Pitch-row between datum hole H is the circle center distance of the inside and outside circle of tilting pad 4, the centre bore of arc surface M and the company of datum hole H
Line is vertical with positive datum level P；The relationship and its work between arc surface and fixation clip positioning side are positioned in view of base body 1
With, if the two is designed to overall structure, great difficulty will be caused to processing, also not can guarantee precision, therefore,
After respectively processing, referring to Fig. 2, then fixation clip 2 is fastened on pedestal sheet with positioning pin 5 and hexagon socket cap head screw 6
On body 1, that is, form fabricated structure.Referring to Fig. 3, movable pressing board 3 is connected on pedestal 1 by B hexagon socket cap head screw 7,
Force is locked.
The working principle of the utility model is：
Referring to Fig.1, the processing unit (plant) of the tilting pad eccentric inner hole of the utility model is with one section on base body 1
Excircle orientation benchmark of the arc surface M as tilting pad 4, the side N using fixation clip 2 are circumferential as the side of tilting pad 4
Limit benchmark, using pedestal datum hole H as the machining benchmark in the tilting pad inner hole center of circle, and using M and two circle center distance of H as can
Incline the eccentricity of tile fragment.The step of processing tilting pad：The first step, centering pedestal P is fastened behind face, then centering datum hole H, setting
Hole heart coordinate is (0,0), i.e., the bore hole center of circle of every piece tile fragment；Tilting pad to be processed is fitted into pedestal, the bottom of with by second step
Seat arc surface M and fixation clip side N is positioned, referring to Fig. 3, then with movable pressing board 3 pass through hexagon socket cap head screw 7 into
Row force locking, in this way, hole machined in tile fragment can be carried out after the completion of clamping.
The processing unit (plant) of processing tilting pad eccentric inner hole by a kind of clamping of utility model quickly and without centering, solution
Every piece of tilting pad all existing clamping used time is longer in production process of having determined, repeats the problem of centering, and accurately ensure that can incline
The eccentric position of tile fragment, improves production efficiency.
