Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, abrasive machine containment envelope, be enclosed within use on the emery wheel of abrasive machine, entangled by emery wheel, comprise enclosing cover 100, inner cap 200 and space collar 300, enclosing cover 100 and inner cap 200 are preferably disc-shaped, space collar 300 is between enclosing cover 100 and inner cap 200, the diameter of space collar 300 and the diameter of enclosing cover 100 adapt, and make can be fixed on around space collar 300 on the edge of enclosing cover 100, are buckled on space collar 300 afterwards by inner cap 200; Between inner cap 200 and space collar 300, arrange a hinge 400, hinged by hinge 400, what realize folding stirs action.
As shown in Figure 1, enclosing cover 100 and inner cap 200 and space collar 300 are provided with opening, quick-detachable for one abrasive disc machine shield is being sleeved on after on abrasive machine, the emery wheel of abrasive machine some exposed by the opening on a kind of quick-detachable abrasive disc machine shield, guarantee the high speed rotational operation of emery wheel.
Abrasive machine containment envelope is also provided with Quick-dismantle component 500, it comprises handle 501, to lock threaded rod 505 with to split nut 506, handle 501 end and to lock threaded rod 505 one end be fixed together, screw thread is provided with to locking threaded rod 505 one end away from handle 501, can be screwed in split nut 506, corresponding is, be fixed on inner cap 200 to split nut, its fixed position is guaranteed after inner cap 200 and enclosing cover 100 fasten, can be inserted in the screwed hole to split nut 506 to lock threaded rod 505, and, directly will be riveted in split nut 506 to the front end of lock threaded rod 505, as shown in fig. 1, split nut 506 is had to one end of screwed hole towards enclosing cover 100, the lock screwed end of threaded rod 505 is positioned to the circulus of space collar 300, namely towards inner cap 200, when inner cap 200 is fastened on after on space collar 300, screwed hole place to split nut 506 is aimed at just to lock threaded rod 505, after this, make lock threaded rod 505 synchronous rotary by turning handle 501, thus make the precession of lock threaded rod 505 in split nut 506, by inner cap 200 and enclosing cover 100, space collar 300 tightens together.Handle 501 is eccentric handle preferably.
In order to make inner cap 200 and space collar 300, can be buckled together fast and accurately when enclosing cover 100 fastens, inner cap 200 and space collar 300 arrange fastening object of reference, as shown in fig. 1, inner cap 200 arranges closed orientation salient point 600, what positioning convex point was corresponding therewith is, space collar 300 arranges the orientation triangle groove 301 of equal number, when inner cap 200 is fastened on space collar 300, can the engaging of closed orientation salient point 600 and orientation triangle groove 301 as benchmark, when the two is fastened togather, mean that inner cap 200 and space collar 300 are just in time in alignment, after this operating personnel's just rotatable handles 501, make to be screwed in split nut 506 to lock threaded rod 505, inner cap 200 is fixed on space collar 300, the emery wheel of abrasive machine just can fence up by a kind of quick-detachable abrasive disc machine shield.
The structure chart of Quick-dismantle component 500 as shown in Figure 2, in fig. 2, handle 501 is fixed together in vertical configuration substantially with to locking threaded rod 505, is convenient to rotary handle 501 in use, be screwed in split nut 506 by what be fixedly connected with it to lock threaded rod 505, implement locking.In order to improve the stability that Quick-dismantle component 500 is installed and used further, buffering spacer 502, spring shim 503 and locating shim 504 is also being arranged with successively on lock threaded rod 505, buffering spacer 502 is positioned at lock threaded rod 505 near the end of handle 501, coordinate spring shim 503 and buffering spacer 502, one can prevent from falling back from enclosing cover 100 come off to lock threaded rod 505, and two come also can to prevent to be screwed in split nut 506 lock threaded rod 505 to be too deeply difficult to back-out.
Fig. 3 is the structural representation to split nut 506 in Quick-dismantle component 500, as shown in the figure, its one end is nut, and the other end is provided with screwed hole, be screwed into for lock threaded rod 505 front end, the reach of the degree of depth of screwed hole and its inside with the externally threaded length of locking on threaded rod 505 is adapted.
Fig. 4 is the local structural graph of the inner cap 200 of a kind of quick-detachable abrasive disc machine shield of the present invention, watch with positive aspect, closed orientation salient point 600 is provided with in the edge of inner cap 200, closed orientation salient point 600 protrudes the surface of inner cap 200, polyhedral can be arranged to, closed orientation salient point 600 can arrange multiple, and its quantity is corresponding with the quantity of the orientation triangle groove 301 on space collar, is convenient to the two and agrees with.
Fig. 5 is the partial structurtes schematic diagram of the cross section on the space collar of a kind of quick-detachable abrasive disc machine shield of the present invention, as shown in the figure, in the edge of space collar 300, multiple orientation triangle groove 301 is set, orientation triangle groove 301 is the edge of space collar 300 is inwardly that triangular shape contraction forms, the distribution of orientation triangle groove 301 is corresponding with the position of the closed orientation salient point 600 on inner cap 200, and its cross-sectional area shrinking the space formed is larger than the cross-sectional area of closed orientation salient point 600, closed orientation salient point 600 can be injected in orientation triangle groove 301.As shown in the figure, an orientation triangle groove 301 can also be offered with the position corresponding to split nut 506 on space collar 300, a fixing hole 302 is offered in the orientation triangle groove 301 at this place, can directly punch process form when offering fixing hole 302, make to extend there through lock threaded rod 505, for fixing to lock threaded rod 505.The diameter of fixing hole 302, slightly larger than the diameter to lock threaded rod 505, when assembling, first will pass from fixing hole 302 lock threaded rod 505, overlap buffering spacer 502, spring shim 503 and locating shim 504 successively afterwards to locking on threaded rod 505.Certainly, in the present invention, the position of fixing hole 302 can convert, and it can be arranged on other position of space collar 300, as long as can make it and be combined split nut 506.
The assembling of quick detach group 500 is after fixing on inner cap 200 split nut 506, (be about to be screwed in split nut 506 locking threaded rod 505) to locking with to locking threaded rod 505, after this process of riveting limit will be carried out to split nut 506 front opening place, make lock threaded rod 505 and split nut 506 is no longer thrown off, and be do screw thread place external diameter serious offense without screw thread place to the dimensional requirement of lock threaded rod 505), when dismantling emery wheel, only quick detach group 500 need be unclamped and up carry, one enclosing cover can be opened automatically because of gravitation, can be for convenience detach and emery wheel is installed, when emery wheel installation, one of only need closing enclosing cover, and quick detach group 500 is depressed into correct position place and is undertaken locking by handle 501.
In the present invention, space collar 300 and enclosing cover 100 can be made monolithic.
By reference to the accompanying drawings the specific embodiment of the present invention is explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess, can also makes a variety of changes under the prerequisite not departing from present inventive concept.
