Embodiment
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 inventive concept of the those skilled in the art to 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, is a kind of blank flange positioning and locking fixture, including fixed
Position bolt 1 and clamp body 6, are 4 fast positioning of blank flange, locking and the grip device of processing.To meet 4 higher of blank flange
Quality requirement, and the processing efficiency that machine adds is improved, carrying out locking fixture structure from easy to operate, registration etc. sets
Meter.As shown in Fig. 2, since 4 back side of blank flange is into the arc-shaped of pan bottom shape, moreover, outer surface will be processed including side,
Therefore, its positioning, clamping are more difficult.The problem of meeting quality and main efficiency be：The side and bottom surface of blank flange 4 are such as
What is processed；How precision in process ensures；Can the processing efficiency of workpiece further improve.
The defects of in order to overcome the prior art, realize the goal of the invention of machining accuracy and production efficiency, the utility model is adopted
The technical solution taken is：
As shown in figure 3, the blank flange positioning and locking fixture of the utility model, the locking fixture is additionally provided with locking and slides
Block 2 and lock sleeve 3, the positioning bolt 1 are connected by thread fitting with lock sleeve 3；The locking sliding block 2 is sleeved on fixed
On the bolt 1 of position；The end of the locking sliding block 2 and lock sleeve 3 uses taper fit；The end of the lock sleeve 3 along its
The busbar of taper, equipped with several flutings 7.
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, moves down locking sliding block 2, fixture locking end size
Become larger, as shown in figure 5, its diameter is by D1 spreadings to D2.During locking, fixture locking end outside diameter forms interference with flange hole
Coordinate, after fixture locking, can ensure that the positioning, locking and processing of instrument.
Multiple flutings 7 so that the end of lock sleeve 3 forms several disjunct limbs, can spreading and tensioner in method tritonope
On the inner wall in the hole of plate 4.
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, forms with the hole of the blank flange 4 and coordinates.
Once lock sleeve 3 is subject to the power of outside spreading, lock sleeve 3 and the hole of the blank flange 4 form matching somebody with somebody for fastening
Close, play the role of clamping and positioning.
As shown in figure 3, it is being equipped with annular groove 5 positioned at the root of the fluting 7, the cylindrical of the lock sleeve 3.Annular
The effect of groove 5 is：Enable the more enough more easily spreadings in end of lock sleeve 3,
Cylindrical formed with the hole of the clamp body 6 of the lock sleeve 3 coordinates；As shown in figure 4, the lock sleeve
3 one end lead to its it is cylindrical on flange, be stuck on the end face of flange of the clamp body 6.The flange limits the axial direction of lock sleeve 3
It is mobile so that when screwing, lock sleeve 3 will not be moved inwardly positioning bolt 1, and produce the problem of rotation is not tight.
Above-mentioned fixture has the following advantages：
1st, operation is convenient, safe, it will be apparent that improves processing efficiency；
2nd, it ensure that the processing quality of the blank flange of high quality requirement, reached the quality requirement of exported product；
3rd, clamp structure is simple, easily manufactured, saves the cost of casting lifting lug early period；
4th, blank flange all surfaces are overcome and process the shortcomings that time-consuming, precision is not high.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implement and from
The limitation of aforesaid way, as long as employing changing for the various unsubstantialities that the methodology of the utility model and technical solution carry out
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.
