Description
The present invention relates to machine-building, particularly relate to a kind of multifunction assembly locating fixture.
Disclosed anchor clamps are a kind of excellences, the instrument that can position and fix processing accessories.
(No.2,537,146 are openly applied in the Germany to known a kind of anchor clamps to two parts location; F 16 B 5/02) be on fitting surface, to process several accurate cone shape holes, wherein lay locating piece-centering ball.
This known clamps can guarantee that two parts location each other is reliably, and the connection between them is a rigidity, this be because, by means of fastening piece, make between described centering ball and the taper hole wall and formed stationary fit.
Yet the load that each locating piece bore of known clamps converges, or on line, its length equals the interface width between ball and the taper hole wall.The result is that the rigidity of connection part is very low.
Also have, the cone shape hole in the very hard parts of fitting surface only can be processed on jig grinding machine one by one, thereby can not carry out the processing of several procedures simultaneously to a part, thereby increase the amount of labour of part processing.
When making locating piece with ball, if there are not other instruments, then (horizontal by various angles) install obliquely, both just flatly dismantled, it must be difficult that ball is taken off from cone shape hole, because in the case, the position of the centre of sphere and the fitting surface of main component are very approaching.It is also very difficult to remove dust, smear metal and cooling liquid from cone shape hole.
Also known multi-functional clamp with various structures, their main component and locating piece also are variously (to see Soviet Union certificate of invention No.795,861; B23 Q3/00).Their distinguishing feature is, a hole of placing fastening piece is arranged in the main component, has two cross one another grooves on fitting surface at least, also has, and after fitting surface is combined, will put into the locating piece of prismatic key in the cavity that is made of groove.Groove is stage shape, and the spacing between the groove equals their width.Prismatic key also is a stage shape, and the bottom of one-level step and another grade step separates, and with screw key is anchored on the main component.
It is very time taking assembling known anchor clamps, because each key is all by a screw.Make known anchor clamps and also require great effort very much, because on main component, must attack this tapped hole, so that screw in screw and compress key.Unavoidably can be gapped between key and cell wall, so main component easily generation skew each other, thereby part can not be had good positioning securely.
The objective of the invention is to design a kind of multifunction assembly locating fixture, locating piece wherein have certain position to, fixed, so just part can be had good positioning securely, designed structure also is easy to quick assembling.
This multifunction assembly locating fixture is to realize above-mentioned purpose like this, the hole that can put into fastening piece is all arranged on each main component of anchor clamps, on fitting surface, have two cross one another grooves at least, after assembling, but load key shape locating piece in the cavity that constitutes by groove.According to the present invention, in the intersection area of groove one annular groove is arranged, a lining wherein is housed, be processed with radial hole above, wherein be fixed with cylindrical keys, it is fixing with the groove on end itself.Key is fixed in the corresponding cavity in the stationary fit mode.Section at this part groove that is fixed with key is trapezoidal, and its degree of depth is greater than the radius of key.
The groove of trapezoidal cross-section and the cylindrical keys that is fixed in the stationary fit mode in this groove make to form a kind of gapless being rigidly connected between the main component, thereby part can be had good positioning securely.
The key of some is fixed on structure in the lining, has improved the assembling speed of disclosed anchor clamps.
To be illustrated the present invention with an example and accompanying drawing below.
The axonometric projection that Figure 1 shows that the multifunction assembly locating fixture that proposes according to the present invention is always schemed, and wherein a part is cut;
Figure 2 shows that according to the present invention a lining in the anchor clamps that propose, on the axonometric projection graph of several cylindrical keys is housed.
As shown in Figure 1, multifunction assembly locating fixture is that two main components 1,2 are fitted together, and on the fitting surface of each main component, the groove 3 of 4 intersections is arranged all, wherein per two on the fitting surface after the assembling, constituted cavity 4.
Groove 3 is intersected with each other, and according to the function and the operational condition of main component 1,2, these grooves are on its symmetry plane or be acute angle, or at right angles.For the quick assembling fixture of energy, on the side of main component fitting surface, can draw coordinate line.
Per two grooves 3 constitute a cavity 4, in reliable stationary fit mode the locating piece of a cylindrical keys 5 are installed therein.Porose 6,7 in the main component 1,2, be used for by fastening piece 8.
In the intersection of groove 3 annular groove 9 is arranged, wherein place a lining 10, straight radial hole 11(Fig. 2 is arranged on the lining).The end of cylindrical keys 5 is fluted 12, and with this key is anchored in the hole 11.
On the lining 10 ring set 13 can be arranged, it can prevent that lining from getting loose from groove 9.If the processing dimension of groove 9 can firmly fix lining 10, also this ring set can be set.
Annular groove 9(Fig. 1) can be concentric with hole 6,7, also can depart from a distance, this depends primarily on design.
Each groove 3 is trapezoidal with the section configuration of cylindrical keys 5 contact position.Groove 3(determines the central axis position of key 5 by it) the degree of depth, greater than the radius of key 5.
The practical experience explanation, after using for many years, the hardness at fitting surface place is the principal element that keeps main component 1,2 dimensional accuracy.For satisfying this respect requirement, be preferably on the universal or special lathe, with these grooves of form grinding instrument retrofit.With the open application number No.2 in above-mentioned Germany, the method for 537, the 146 processing cone shape holes that propose relatively for quickening the grinding process of groove, can be carried out the processing of several operations simultaneously to each main component.It should be noted that each groove in disclosed anchor clamps, replace by many holes.To the every bit in these holes, must process separately, and reach the size that meets tolerance.
The assembly process of disclosed multifunction assembly locating fixture such as following.
Earlier cylindrical keys 5 is fixed on the lining 10, according to the direction of groove 3, this part assembly parts is put in the groove 9 of main component 1 then.When main component 2 is installed, must make the groove 3 above it aim at cylindrical keys 5, then the fastening piece in the hole 6,7 is screwed.This fastening force can make the wall of groove 3 produce juxtaposition metamorphose, makes key 5 distortion simultaneously.Like this, just, can make key 5 and cavity 4 constitute a reliable stationary fit.
At the disclosed anchor clamps that are used for locating element, the cutting force that acts on the main component 1,2 will reach on the key 5, and act on the very narrow contact-making surface that equals key 5 length, consequently make to form one between two main components and be rigidly connected. Being rigidly connected is conducive to fixedlying positioning of part, thereby is conducive to its accurate processing.
The groove of disclosed anchor clamps is easy to mould and arrives, thereby need not anyly utilize instrument can dispose at an easy rate dust, smear metal and cooling fluid. Because the main component that is in contact with one another on a plane can tilt arbitrarily (becoming various angles with horizontal plane), thereby installation or removal all are not difficult. For realizing this point, can adopt being fixed with on the lining structure of necessary number key.
In addition, the lining on the disclosed anchor clamps is fixed with the sort of of cylindrical keys above namely, can be applicable to machine components with various sclerosis and is installed to together frequent machine components of dismounting of occasion, particularly those very high positioning accuracies that need.
