Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, with help those skilled in the art to the inventive concept of the utility model, technical solution have it is more complete, accurate and
Deep understanding.
The structure of the utility model as expressed by Fig. 1 to Fig. 5 for a kind of positioning of blank flange rapid processing, clamps knot
Structure, including positioning bolt 1 and clamp body 6 are blank flange 4 quickly positioning, locking and the grip devices processed.To meet flange
The requirement of 4 higher quality of blind plate, and the processing efficiency that machine adds is improved, carry out locking folder from easy to operate, registration etc.
Lamps structure designs.As shown in Fig. 2, since 4 back side of blank flange is at the arc-shaped of pan bottom shape, wanted moreover, outer surface includes side
It is processed, therefore, positioning clamps more difficulty.Meet quality and the main problem of efficiency is：The side of blank flange 4
How face and bottom surface process；How precision in process ensures；Can the processing efficiency of workpiece further increase.
In order to overcome the deficiencies of existing technologies, realize that the goal of the invention of machining accuracy and production efficiency, the utility model are adopted
The technical solution taken is：
As shown in figure 3, the blank flange rapid processing positioning of the utility model, clamping structure, the locking fixture is also
Equipped with locking sliding block 2 and lock sleeve 3, the positioning bolt 1 is connect by screw-thread fit with lock sleeve 3；The locking is slided
Block 2 is sleeved on positioning bolt 1；The end of the locking sliding block 2 and lock sleeve 3 uses taper fit；The lock sleeve
3 end is along the busbar of its taper, if there are four fluting 7, the groove width of each fluting 7 is 4mm~5mm.
The specification of the positioning bolt 1 is M20.
Four flutings 7 are uniformly distributed on the circumference using the axis of lock sleeve 3 as the center of circle.
Locking device injects row positioning by DN1600 blank flanges 4 and disk and fixes, and ensure that the back side and side of blind plate
Face can process.The above-mentioned locking fixture device of the utility model, can quick locking positioning, it is easy to operate, and ensure
The dimensional accuracy of blank flange 4 in process.
As shown in figure 4, locking device is mainly made of positioning bolt 1, locking sliding block 2,3 three parts of lock sleeve.Its work
Mode is：By positioning bolt 1, the displacement of locking sliding block 2 is adjusted, so that locking sliding block 2 is moved down, fixture locking end size
Become larger, as shown in figure 5, its diameter is by D1 spreadings to D2.During locking, fixture locking end outer diameter forms interference with flange hole
Coordinate, after fixture locking, can ensure that the positioning, locking and processing of tool.
Four flutings 7 spreading and can rise so that the end of lock sleeve 3 forms four and is not attached to and the identical limb of size
Tightly on the inner wall of the flange hole of blank flange 4, keep its expanding force uniform.
Operating personnel lock 4 positioning bolts 1 by interior hex tool, and blank flange 4 is fixed on the positioning.
The outer surface at end 7 positions of fluting of the lock sleeve 3, the flange hole formation with the blank flange 4 are matched
It closes.
Once lock sleeve 3 is formed matching for fastening by the power of outside spreading, lock sleeve 3 and the hole of the blank flange 4
It closes, plays the role of clamping and positioning.
As shown in figure 5, a diameter of 59mm of the flange hole, the locking end outer diameter of the lock sleeve 3 is D1 sizes, is led to
D2 sizes can be reached by crossing the effect of locking sliding block 2, and D2 size ranges are 58mm~61.4mm；When outside the locking end of lock sleeve 3
It is interference fit with the flange hole when diameter D2 sizes are more than 59mm, to realize positioning, the folder of the blank flange 4
Tightly.
As shown in figure 3, being equipped with annular groove 5 in the outer circle positioned at the root of the fluting 7, the lock sleeve 3.Annular
The effect of slot 5 is：Enable the more enough more easily spreadings in the end of lock sleeve 3；
The hole of the outer circle of the lock sleeve 3 and the clamp body 6, which is formed, to be coordinated；As shown in figure 4, the lock sleeve
3 one end leads to the flange in its outer circle, is stuck on the end face of flange of the clamp body 6.The flange limits the axis of lock sleeve 3
To movement so that when screwing, lock sleeve 3 will not be moved inwardly positioning bolt 1, and it is not tight to lead to the problem of rotation.
Above-mentioned fixture has the following advantages：
1, operation is convenient, safe, it will be apparent that improves processing efficiency；
2, the processing quality that ensure that the blank flange that high quality requires, has reached the quality requirement of exported product；
3, clamp structure is simple, easily manufactured, saves the cost of casting lifting lug early period；
4, the blank flange all surfaces processing disadvantage that time-consuming, precision is not high is overcome.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using the methodology of the utility model and various unsubstantialities that technical solution carries out change
Into, or it is not improved the design of the utility model and technical solution are directly applied into other occasions, in the utility model
Protection domain within.
