Offer on the described mandrel sidewall and the cooresponding chute in radially-directed hole, the inclined-plane of mandrel sidewall is arranged on the chute bottom, and described slide block inner end surface is all the inclined-plane, and the angle of inclination on two inclined-planes is identical.
Described magnet is positioned at slide block and cooperates with mandrel on the slide block at place, inclined-plane, and described slide block is offered magnet opening on the inclined-plane, in establish magnet.
Described mandrel outer wall front end is provided with the annular table terrace of two different-diameters, and the orienting sleeve correspondence is provided with two annular table terraces with the mandrel bearing fit, is equipped with the slide block of same structure on each annular table terrace.
Be symmetrical arranged six radially-directed holes on the circumferencial direction of each annular table terrace of described orienting sleeve, corresponding radially-directed hole is provided with six chutes on the circumferencial direction of each annular table terrace of mandrel, is embedded slide block in described radially-directed hole and the chute movingly.
Spacing pin is set on the described mandrel, vertically offers limit sliding chutes on the orienting sleeve with spacing pin running-fit.
Described mandrel leading section is offered the spring pilot hole of indent, and described retracing spring is positioned at this pilot hole.
The utility model improves the structure of original expansion type body paper chuck, in slide block and mandrel, be provided with magnet opening on arbitrary parts, magnet is set in the magnet opening, because the adsorption of magnet, the state that slide block and mandrel are kept in touch always, when mandrel resets, drive slide block and reset together, finish the automatic contractive action of slide block.So just save artificial auxiliary action of shrinking, saved unnecessary working link, time saving and energy saving, increase work efficiency, save production cost.
Description of drawings
Fig. 1 is a mode of operation cutaway view of the present utility model;
Fig. 2 is an off working state cutaway view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises mandrel 1, be with orienting sleeve 4 on the mandrel 1 movingly, between orienting sleeve 4 inner chamber front end faces and the mandrel 1 axial retracing spring 9 is housed, orienting sleeve 4 is provided with the radially-directed hole 3 that is no less than three on the sidewall circumferencial direction, be embedded with slide block 2 in the radially-directed hole 3 movingly, slide block 2 inner end surfaces are vertically arranged with the inclined-plane 1a that turns forward facing on mandrel 1 sidewall, arbitrary parts are provided with magnet opening 6 in described slide block 2 and the mandrel 1, and magnet 5 is set in the magnet opening 6.
In the present embodiment, mandrel 1 outer wall front end is provided with the annular table terrace of two different-diameters, and orienting sleeve 4 correspondences are provided with two annular table terraces with mandrel 1 bearing fit.Be symmetrical arranged six radially-directed holes 3,31 on the circumferencial direction of two annular table terraces of orienting sleeve 4 respectively, corresponding radially-directed hole 3,31 is provided with six chutes 11 respectively on two annular table terrace circumferencial directions of mandrel 1, is embedded with slide block 2,21 in radially-directed hole 3,31 and the chute 11 movingly.The inclined-plane 1a of mandrel 1 sidewall is arranged on chute 11 bottoms, and inclined-plane 1a is identical with the angle of inclination of slide block 2,21 inner inclined-plane 2a.Offer magnet opening 6,61 on the inner inclined-plane 2a, in establish magnet 5,51, be in contact with one another with inclined-plane 1a then and cooperate.Spacing pin 7 is set on the mandrel 1, vertically offers limit sliding chutes 8 on the orienting sleeve 4 with spacing pin 7 running-fits.Mandrel 1 leading section is offered the spring pilot hole 10 of indent, and spring pilot hole 10 internal fixation connect spring 9.7 pairs of orienting sleeves 4 of pin play the longitudinal spacing effect.
During work, present embodiment is fixed on the support, if the body paper inside barrel diameter is less, move two end supports the front end annular table terrace of orienting sleeve 4 is put into the body paper reel, promote mandrel 1, its pressuring spring 9 is moved inwards, simultaneously under the inner inclined-plane 2a effect of inclined-plane 1a and slide block 21, slide block 21 is being driven along chute 11 and radially-directed hole 31 protruding by mandrel 1, the slide block 21 that stretches out props up the madial wall of body paper reel, and is until slide block 21 that the paper roll collet chuck is tight under external force.Slide block 21 is kept in touch with mandrel 1 under the adsorption of magnet 51 always in this process.
After wearing the paper success, support is laterally removed, under the effect of external force and spring restoring force, mandrel 1 will skid off orienting sleeve 4 gradually, because the absorption of magnet 51 is kept in touch slide block 21 and mandrel 1, when mandrel 1 slips away orienting sleeve 4, also drive slide block 21 simultaneously and inwardly shrink, thereby finish the automatic contraction of slide block 21.
When if the body paper inside barrel diameter is big, then move two end supports the rear end annular table terrace of orienting sleeve 4 is put into the body paper reel, finish clamping and contractive action with same operation.The parts that this time participate in action are: rear end annular table terrace, mandrel 1, inclined-plane 1a, slide block 2, inner inclined-plane 2a, radially-directed hole 3, orienting sleeve 4, magnet 5 and limit spring 9.
When slide block is finished one action and entered down task like this, just need not manually assist and shrink slide block, save unnecessary working link, time saving and energy saving, simple to operate.
The utility model is not limited to the foregoing description, and for example: what the number in radially-directed hole 3 can be for more than three is a plurality of arbitrarily; The shape of magnet 5 can be the flattened cylindrical body, also can be cuboid or square, and magnet opening 6 is done respective change according to magnet 5 shapes; The number of magnet 5 and magnet opening 6 can be for more than two.
