Description
Technical field
The invention belongs to the technical field of cast tube product manufacture equipment.A kind of more particularly it relates to flange
Blind plate positioning and locking fixture.
Background technology
1st, the blank flange back side is into the circular arc of pan bottom shape, particularly DN1600 blank flanges external diameter 1930mm, specification compared with
Greatly, fast positioning is difficult on lathe, is clamped, Set and Positioning is more difficult, therefore, outward appearance and dimensional accuracy in process
More difficult control；
2nd, the processing method of the conventional blind plate of prior art is：Cast out hanger in blind plate both sides, pass through hanger and workbench
It is fixed, inserted using DN1600 disks as frock support, carries out reverse side processing,；The processing of such a method is very time-consuming；Processing
Finishing rear lifting lug also needs to remove；And hanger can influence the presentation quality of casting after removing, the waste of manpower, raw material is caused.
3rd, present user is to proposing higher requirement to product quality：It is required that blank flange mounting surface is carried out entirely to add
Work, it is desirable to which outward appearance precision is higher, and the surface roughness requirements after processing reach Ra3.2~Ra1.6um；Therefore, above-mentioned processing side
Method is difficult to the requirement for meeting its quality requirement and production efficiency.
The content of the invention
The present invention provides a kind of blank flange positioning and locking fixture, and the purpose is to improve machining accuracy and the life of blank flange
Produce efficiency.
To achieve these goals, the technical scheme taken of the present invention is：
The blank flange positioning and locking fixture of the present invention, including bolt and clamp body；Described locking fixture is also set
There are locking sliding block and lock sleeve, described bolt is coordinated by screw thread to be connected with lock sleeve；Described locking sliding block suit
On bolt；Described locking sliding block and the end of lock sleeve use taper fit；The end of described lock sleeve along its
The bus of taper, provided with several flutings.
The outer surface at the end fluting position of described lock sleeve, forms with the hole of described blank flange and coordinates.
Annular groove is being provided with positioned at the root of described fluting, the cylindrical of described lock sleeve.
Cylindrical formed with the hole of described clamp body of described lock sleeve coordinates；One end of described lock sleeve leads to outside it
Flange on circle, it is stuck on the end face of flange of described clamp body.
The present invention uses above-mentioned technical proposal so that operation is convenient, safety, it will be apparent that improves processing efficiency；Protect
The crudy of blank flange has been demonstrate,proved, has reached the quality requirement of exported product；Fixture makes simply, saves casting early stage and hangs
The cost of ear；Overcome blank flange and process the shortcomings that time-consuming, precision is not high entirely.

Embodiment
Below against accompanying drawing, by the description to embodiment, embodiment of the invention is made further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical scheme
Solution.
Structure of the invention as expressed by Fig. 1 to Fig. 5, it is a kind of blank flange positioning and locking fixture, including positioning spiral shell
Bolt 1 and clamp body 6, it is the fast positioning of blank flange 4, locking and the grip device of processing.To meet the higher quality of blank flange 4
It is required that and improve the processing efficiency that machine adds, carry out locking fixture structure design from easy to operate, registration etc..Such as
Shown in Fig. 2, because the back side of blank flange 4 is into the circular arc of pan bottom shape, moreover, outer surface will be processed including side, therefore,
It positions, clamps more difficulty.The problem of meeting quality and main efficiency be：How the side and bottom surface of blank flange 4 add
Work；How precision in process ensures；Can the processing efficiency of workpiece further improve.
The defects of in order to overcome prior art, the goal of the invention of machining accuracy and production efficiency is realized, what the present invention took
Technical scheme is：
As shown in figure 3, the blank flange positioning and locking fixture of the present invention, described locking fixture are additionally provided with locking sliding block 2
With lock sleeve 3, described bolt 1 is coordinated by screw thread to be connected with lock sleeve 3；Described locking sliding block 2 is sleeved on positioning
On bolt 1；The end of described locking sliding block 2 and lock sleeve 3 uses taper fit；Bored along it the end of described lock sleeve 3
The bus of degree, provided with several flutings 7.
Locking device injects row positioning by DN1600 blank flanges 4 and disk and fixed, and ensure that the back side and side of blind plate
Face can process.The above-mentioned locking fixture device of the present invention, can quick locking positioning, it is easy to operate, and ensure flange
The dimensional accuracy of blind plate 4 in process.
As shown in figure 4, locking device is mainly made up of bolt 1, locking sliding block 2, the three parts of lock sleeve 3.Its work
Mode is：By bolt 1, the displacement of locking sliding block 2 is adjusted, moves down locking sliding block 2, fixture locking end size
Become big, as shown in figure 5, its diameter is by D1 spreadings to D2.During locking, fixture locking end external diameter forms interference with flange hole
Coordinate, after fixture locking, the positioning, locking and processing of instrument can be ensure that.
Multiple flutings 7 cause the end of lock sleeve 3 to form several disjunct limbs, can spreading and tensioner in method tritonope
On the inwall in the hole of plate 4.
Operating personnel lock 4 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 described lock sleeve 3, forms with the hole of described blank flange 4 and coordinates.
Once lock sleeve 3 is formed matching somebody with somebody for fastening by the power of outside spreading, the hole of lock sleeve 3 and described blank flange 4
Close, play a part of clamping and position.
As shown in figure 3, it is being provided with annular groove 5 positioned at the root of described fluting 7, the cylindrical of described 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 described clamp body 6 of described lock sleeve 3 coordinates；As shown in figure 4, described lock sleeve
3 one end lead to its it is cylindrical on flange, be stuck on the end face of flange of described 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 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, the crudy of the blank flange of high quality requirement is ensure that, has reached the quality requirement of exported product；
3rd, clamp structure is simple, easily manufactured, saves the cost of casting hanger early stage；
4th, blank flange all surfaces are overcome and process the shortcomings that time-consuming, precision is not high.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that present invention specific implementation is not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
