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, for a kind of positioning of blank flange rapid processing, clamping structure, bag Bolt 1 and clamp body 6 are included, is the fast positioning of blank flange 4, locking and the grip device of processing.To meet blank flange 4 Higher quality requirement, and the processing efficiency that machine adds is improved, carry out locking fixture structure from easy to operate, registration etc. Design.As shown in Fig. 2 because the back side of blank flange 4 is into the circular arc of pan bottom shape, to be added moreover, outer surface includes side Work, therefore, it positions, clamps more difficulty.The problem of meeting quality and main efficiency be:The side and bottom of blank flange 4 How face processes;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 rapid processing positioning of the present invention, clamping structure, described locking fixture are additionally provided with Locking sliding block 2 and lock sleeve 3, described bolt 1 is coordinated by screw thread to be connected with lock sleeve 3;2 sets of described locking sliding block On bolt 1;The end of described locking sliding block 2 and lock sleeve 3 uses taper fit;The end of described lock sleeve 3 Bus of the portion along its taper, provided with four flutings 7, the groove width of each fluting 7 is 4mm~5mm.
The specification of described bolt 1 is M20.
Four described flutings 7 are uniform 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 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.
Four flutings 7 cause the end of lock sleeve 3 to form four and be not attached to and size identical limb, spreading and can rise Tightly on the inwall of the flange hole of blank flange 4, make its expanding force uniform.
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 flange hole of described blank flange 4 and matches somebody with somebody Close.
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 5, a diameter of 59mm of described flange hole, the locking end external diameter of described 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 described flange hole when footpath D2 sizes are more than 59mm, so as to realize the positioning of described blank flange 4, folder Tightly.
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.
