Abstract
The invention provides a paper element chuck. The paper element chuck comprises a baffle I, a baffle II and a baffle III which are connected in sequence through connecting pieces. The baffle I, the baffle II and the baffle III are parallel to one another. A center shaft in threaded connection with the baffle I, the baffle II and the baffle III penetrates through the center of the baffle I, the center of the baffle II and the center of the baffle III. An inner wedge-shaped driving head is fixedly connected to the section, located between the baffle I and the baffle II, of the center shaft. The axial length of the inner wedge-shaped driving head is smaller than the distance between the opposite side faces of the baffle I and the baffle II. The periphery of the inner wedge-shaped driving head is provided with an outer wedge-shaped block which is driven by the inner wedge-shaped driving head and is capable of moving in the radial direction. The section, located between the baffle II and the baffle III, of the center shaft is a threaded rod section. The threaded rod section is provided with a driving rotary wheel matched with the threaded rod section. According to the paper element chuck, abrasion to a paper element by the paper element chuck can be reduced, so the service life of the paper element is prolonged, and the production cost is lowered.

Detailed description of the invention
For the technical characterstic of this programme can be clearly demonstrated, below by detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of refill chuck, as shown in the figure, it comprises the baffle plate I 3 connected in turn by connector, baffle plate II 7 and baffle plate III 10, preferred baffle plate I 3, baffle plate II 7 and baffle plate III 10 are circular slab, specifically, baffle plate I 3 and baffle plate II 7 are connected and fixed by multiple connecting rod (stud 16 as M20), baffle plate II 7 and baffle plate III 10 are connected and fixed by multiple connecting rod (stud 16 as M20), make baffle plate I 3, spacing between baffle plate II 7 and baffle plate III 10 immobilizes, by connecting rod by baffle plate I 3, baffle plate II 7 is firmly connected as a whole with baffle plate III 10.Described baffle plate I 3, baffle plate II 7 and baffle plate III 10 are parallel to each other, and the center of described baffle plate I 3, baffle plate II 7 and baffle plate III 10, through there being the central shaft 11 be threaded with three, makes central shaft 11 can move horizontally along baffle plate I 3, baffle plate II 7 and baffle plate III 10.
One section on described central shaft 11 between baffle plate I 3 and baffle plate II 7 is fixedly connected with interior wedge shape driving head 1, this interior wedge shape driving head 1 is truncated cone-shaped revolving body or centrally multiple wedges of being evenly arranged of axle 11 circumference, the two ends of interior wedge shape driving head 1 are respectively arranged with guide post 13, described baffle plate I 3 and baffle plate II 7 are respectively arranged with the pilot hole coordinated with guide post 13, guide post 13 and pilot hole are matched in clearance, coordinated with pilot hole by guide post 13, the stability of wedge shape driving head 1 movement in ensureing.The axial length of described interior wedge shape driving head 1 is less than the spacing between the opposite flank of baffle plate I 3 and baffle plate II 7, and interior wedge shape driving head 1 level of synchronization can be driven during to ensure that central shaft 11 moves to move.
The periphery of described interior wedge shape driving head 1 is provided with and is driven and the outer wedge 2 that can move radially by it.Described outer wedge 2 is along the circumferential direction evenly arranged, the outside of described outer wedge 2 is fixed with the block 4 that rises, the two ends of described interior wedge shape driving head 1 are fixedly connected with the guiding support bar 6 coordinated with baffle plate I 3 and baffle plate II 7 respectively, baffle plate I 3 and baffle plate II 7 are respectively arranged with the radial bar hole 8 coordinated with guiding support bar 6, the radial direction of guiding support bar 6 and radial bar hole 8(centrally axle 11) be matched in clearance, above-mentioned outer wedge 2 is along the circumferential direction evenly arranged, the outside of described outer wedge 2 is fixed with arc and rises block 4, this block 4 that rises can increase the contact area of itself and refill chuck, when interior wedge shape driving head 1 moves, gradually outer wedge 2 and the block 4 that rises are strutted, make the block 4 stretching refill that rises.
One section in described central shaft 11 between baffle plate II 7 and baffle plate III 10 is spiro rod section, described spiro rod section is provided with the driving runner be mated, this driving runner is threaded opening handwheel 12, and handwheel 12 can be moved back and forth by screw thread smoothly between baffle plate II 7 and baffle plate III 10.
Come off to prevent central shaft 11 baffle plate I 3 in moving process, the nut 5(that coordinates with baffle plate I 3 is provided with as the nut of M30) in one end of central shaft 11, when interior wedge shape driving head 1 return (moving right), nut 5 coordinates with baffle plate I 3, carry out spacing to central shaft 11, thus prevent central shaft 11 and baffle plate I 3 from departing from; The opposite end of baffle plate II 7 and baffle plate III 10 is respectively arranged with the guide cylinder 9 coordinated with central shaft 11, and guide cylinder 9 one aspect can lead to central shaft 11, can also coordinate with handwheel 12, as the spacing benchmark that handwheel 12 moves left and right.
When handwheel 12 by threading action to baffle plate II 7 time, baffle plate II 7 limits handwheel 12 and continues motion, specifically, that guide cylinder 9 on baffle plate II 7 limits handwheel 12 and continues motion, occur between handwheel 12 and baffle plate II 7 interacting, this effect makes central shaft 11 start to move forward, central shaft 11 motion has forward driven interior wedge shape driving head 1 to travel forward, due to the restriction of the external wedge 2 of baffle plate I 3, outer wedge 2 can be made to move along the direction that the inclined-plane contacted with interior wedge shape driving head 1 is contrary relative to interior wedge shape driving head 1, due to the effect on this inclined-plane, make outer wedge 2 at radial direction constantly outside spreading.When the outside rising of outer wedge 2, the guiding support bar 6 of its both sides can move along the radial bar hole 8 on baffle plate II 7 and baffle plate III 10.On central shaft 11, be preferably provided with four to wedge inside and outside cooperatively interacting, so when central shaft 11 runs forward, the radial direction spreading outward that four pieces of outer wedges 2 can be synchronous, reaches the effect of tensioner refill.
When refill is backed off by needs, handwheel 12 can be made to move backward, when arriving baffle plate III 10, in like manner, due to the restriction that the baffle plate III 10 pairs of handwheels 12 run, make central shaft 11 and on interior wedge shape driving head 1 backward (right side) move, so just make outer wedge 2 fall after rise in radial direction, unclamp refill, facilitate refill to take off from refill chuck.
This refill chuck is fully mechanical structure, and structure is simple, failure rate is low, has good interchangeability and versatility, can as the template of different size refill chuck of the same type.Can equipment operation condition be improved, reduce energy consumption, reduce the abrasion condition of key components and parts, and then extend the service life of related components.
Can pass through without the technical characteristic described in the present invention or adopt existing techniques in realizing; do not repeat them here; certainly; above-mentioned explanation is not limitation of the present invention; the present invention is also not limited in above-mentioned embodiment; the change that those of ordinary skill in the art makes in essential scope of the present invention, remodeling, interpolation or replacement, also should belong to protection scope of the present invention.
