Specific implementation mode
In order to which the technical solution of the utility model is explained further, come pair below by a kind of specific embodiment combination attached drawing
The utility model is described in detail.
A kind of sliding beam of elastic axle sleeve of tool disclosed by the utility model, as depicted in figs. 1 and 2, including main body of cross-beam 1
With elastic axle sleeve 2, the elastic axle sleeve 2 for release to be passed through and realized for slide bar 3 or clamps slide bar 3, i.e. both used by the elastic axle sleeve 2
It uses in sliding shaft sleeve, and is used for fastening shaft sleeve, the sliding beam of the structure is applied on engraving machine, the entirety of engraving machine
Surface structure can be simpler, succinctly.Elastic axle sleeve 2 is the main improvements of the utility model, and the connection of concrete structure position is closed
System is described in detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of elastic axle sleeve 2 includes outer sleeve body 21, adjusting sleeve 22 and split hub 23, the split
Set 23 is put together by 231 annular of polylith split block, i.e., two-by-two split block 231 be all separation be not fixed connection enclose split
Set 23, the split hub 23 is embedded in outer sleeve body 21, and the adjusting sleeve 23 is embedded in one end of outer sleeve body 21, the outer sleeve body
21 other end is equipped with disconnecting prevention structure 211, and for preventing split hub 23 from falling off from the end, the adjusting sleeve 22 can be with respect to housing
Body 21 is promoted or is exited, and the inner end inner surface of the adjusting sleeve 22 and the end outer surface of split block 221 are that corresponding tilt coordinates
Inclined surface structure 24, in conjunction with attached drawing, it can be seen that when promoting adjusting sleeve 22, spelling can be pushed under the action of structure 24 in inclined surface
231 radial action of block is closed, split hub 23 is whole to reduce diameter, is adjacent to slide bar 3, therefore more promote and can hold slide bar 3 tightly, real
The effect now fastened, if you do not need to fastening, but used as matched sliding shaft sleeve, then it is advanced into and is bonded i.e. with slide bar
Can, and when exiting, split hub 23 loses motive force, and adjusting sleeve 22 exits that also to have conceded split block 231 radially movable
Space, therefore can push split block 231 under the action of other active forces；Adjusting sleeve 22 described in the present embodiment and split block
It is equipped with Anti-releasing position limiting structure between 231 and is used to limit the voluntary activity of split block 231, and prevents the abjection of split block 231,
Structure can be that 22 inner end lateral surface of the adjusting sleeve is formed with step ring 221 or corresponds each split block 231 as shown in Figure 1
Step groove 221,231 lateral wall of split block are convexly equipped with the limited block 2311 being embedded in step ring/step groove 221, in this way
It can prevent split block 231 from deviating from, step ring/step groove 221 will have enough spaces radial for split block 231 here certainly
For Activity time limit position block 2311 in its corresponding activity, split block 231 can also be limited by being also set as one-to-one step groove 221
Around axial activity, preferably defines limited block 2311, i.e., preferably define the activity direction of split block 231；May be used also
For as shown in Fig. 2, being axially convexly equipped with positive stop strip 2312, the end of the positive stop strip 2312 on the lateral wall of the split block 231
22 inner end lateral surface of adjusting sleeve is extended to, the limit being embedded in for positive stop strip 2312 is axially offered on the madial wall of the outer sleeve body 21
Position slot 212, the structure are equally reached above-mentioned effect.
To make split block 231 when adjusting sleeve 22 exits, can automatic movable realize the effect that expands of split hub 23,
Further as shown in Fig. 2, corresponding to each split block 231 on the side wall of the outer sleeve body 21 offers embedded hole 213 in the present embodiment,
Tension spring 214 is embedded in the embedded hole 213, one end of the tension spring 214 is connected on split block 231, the drawing
The other end of power spring 214 is fixedly connected on by fixed connection structure on outer sleeve body 21, the split hub when adjusting sleeve 22 promotes
23, which reduce diameter, elongates tension spring 214, and tension spring 214 generates elastic-restoring force, therefore when adjusting sleeve 22 exits, the work
Firmly split block 231 can be pulled to realize effect that split hub 23 expands.
Above-mentioned disconnecting prevention structure 211, can be in the present embodiment outer sleeve body 21 madial wall on be formed with for block split block end
The step ring in portion, the structure can be molded when manufacturing outer sleeve body, as shown in Figure 1；Or can be, as shown in Figure 2, it is embedded outer
Interior set body in 21 end of body realizes the effect for blocking 231 end of split block by adding interior set body formation step structure,
It is connected by connection structure between the interior set body and outer sleeve body 21, the connection structure can be the interior set body and outer sleeve body 21
On be respectively equipped with the helicitic texture for matching and screwing togather, i.e. direct threads connection, alternatively, being interior set body outer end outer edge
With offer corresponding threaded hole respectively on outer sleeve body 21 and locked and connected by bolt, i.e., it is external to lock and connect, such as institute in figure
Show, the structure of interior set body is set, may further be provided, as shown in the figure, the inner end inner surface and split block of the interior set body
231 end outer surface is corresponding the second inclined surface structure 26 for tilting cooperation, has the function of such as above-mentioned inclined surface structure 24
Effect, above-mentioned step groove 221, limited block 2311, positive stop strip 2312 same use of structure setting at this, realize and similarly imitate
Fruit, while the activity of split block 231 and active force also may make more to balance, steadily.
Propulsion of the adjusting sleeve 22 with respect to outer sleeve body 21 how is realized in the present embodiment and is exited, as shown in fig. 1, the tune
It is respectively equipped with the helicitic texture for matching and screwing togather on the whole series 22 and outer sleeve body 21, to realize its propulsion by rotating adjusting sleeve 22
Or exit, it is simple in structure, by manually being operated using work when adjustment, for ease of operation, outside the outer end of the adjusting sleeve 22
