Abstract
The utility model relates to an ejection device for a large-capacity centrifuge rotor. Most of the driving shaft and the rotor body of the existing large-capacity centrifuge are matched with each other by adopting a small-taper conical surface; and due to the adoption of the small-taper conical surface for matching, the rotor is easy to assemble and difficult to disassemble. The utility model aims at providing the ejection device for the large-capacity centrifuge rotor, which is simple and convenient to disassemble and assemble and can save raw material, reduce manufacturing cost and save a large amount of manpower resource and material resource. The device comprises a fan hood cover, a locknut, a core sleeve bolt, a hexagonal sleeve, a rotor body, a flexible driving shaft and a fan hood; the rotor body is arranged on the flexible driving shaft; the hexagonal sleeve is arranged on the driving shaft; the hexagonal sleeve is connected with the rotor body by a screw; a hexagonal hole on the hexagonal sleeve corresponds to the hexagonal body on the driving shaft; the hexagonal sleeve is provided with the core sleeve bolt; and the fan hood is arranged on the upper surface of the rotor body, is connected with the rotor body by the screw and is fixedly locked by the locknut.
Description
Technical field:
The utility model belongs to the mechanical handling technical field, is specifically related to be used for more a kind of big capacity centrifuge rotor liftout attachment of exchanging rotor of big capacity centrifuge.
Background technology
As everyone knows, big capacity centrifuge rotor, institute's bringing onto load is many, requires transfer larger torque at driving shaft and rotor matching part, is cooperated by conelet degree taper seat, with transmitting moment of torsion and self-centering function.Big capacity centrifuge driving shaft adopts conelet degree taper seat to cooperate with the rotor block great majority, and adopt conelet degree taper seat to cooperate, cartridge rotor is easy, unloads the rotor difficulty, and existing big capacity centrifugal basket liftout attachment is by auxiliary friction top, be fixed on the rotor block with three M4 screws, unscrew locking nut then,, throw off from conelet degree taper seat rotor jack-up, back out three M4 screws again, take off friction top.Back out locking nut, take off again and turn, when dismantling three M4 screws, the length unanimity that keep three M4 screws to back-out, otherwise friction top tilts, and rotor block tilts, and twists the locking nut effort, the parts of cumbersome required instrument of operating process and dismounting are many, time-consuming, very not easy like this.
Summary of the invention
The purpose of this utility model is to provide the parts that remove and install easy, used instrument and dismounting few according to above-mentioned weak point, and the reduction manufacturing cost that can save material is saved a kind of big capacity centrifuge rotor liftout attachment of a large amount of manpower and materials.
The utility model is to realize like this, this device comprises the fan housing lid, locking nut, the core retainer plate bolt, six sides cover, rotor block, flexible drive shaft, fan housing, rotor is installed on the flexible drive shaft, flexible drive shaft above the rotor is provided with six sides cover, six sides apply mechanically screw and connect with rotor block, the hexagonal hole that its six side puts is corresponding with hexahedron on the driving shaft, put six sides and to be installed on the core retainer plate bolt, screw thread on six sides and core retainer plate bolt link, fan housing is installed in above the rotor block, link with screw with rotor block, rotate with rotor block, rotor block on flexible drive shaft, is installed on the fan housing lid at locking nut and fan housing upper end by the locking nut fixing and locking in addition.
Description of drawings
Accompanying drawing: be the utility model structural representation
Figure grade: 1 fan housing lid, 2 locking nuts, 3 core retainer plate bolts, 4 six sides cover, 5 rotor blocks, 6 flexible drive shafts, 7 fan housings.
The specific embodiment:
Big capacity centrifuge rotor liftout attachment of the present utility model, it includes fan housing lid (1), locking nut (2), core retainer plate bolt (3), six sides overlap (4), rotor block (5), flexible drive shaft (6), fan housing (7), rotor block (5) is installed on the flexible drive shaft (6), flexible drive shaft (6) top on rotor block (5) is provided with six sides covers (4), six sides apply mechanically screw and connect with rotor block (5), upward hexahedron is corresponding with driving shaft (6) for hexagonal hole on its six sides cover (4), on six sides covers (4), be installed on core retainer plate bolt (3), screw thread and core retainer plate bolt on the six sides covers (4) link, fan housing (7) is installed in above the rotor block (5), links with rotor block (5); With the rotor block rotation, by locking nut (2) fixing and locking rotor block (5), go up central authorities at locking nut (2) and fan housing (7) in addition and be installed on fan housing lid (1), fix by locking screw.
The big capacity centrifuge rotor of the utility model liftout attachment, it has used lever principle, the core retainer plate bolt is screwed into six sides cover, revolve the 2-3 circle with spanner or bar inverse clock rotational lock nut, rotor block jack-up, rotor block is thrown off from conelet degree taper seat, then locking nut dextrorotation 1.5-2.5 is enclosed, rotor is fallen naturally on the driving shaft and is backed out respectively with handgrip core retainer plate bolt and tight split nut, at this moment just can easily take off rotor block.
Claims (2)
1. one kind big capacity centrifuge rotor liftout attachment, it comprises fan housing lid (1), locking nut (2), core retainer plate bolt (3), six sides overlap (4), rotor block (5), flexible drive shaft (6), fan housing (7), it is characterized in that rotor block (5) is installed on the flexible drive shaft (6), flexible drive shaft (6) top on rotor block (5) is provided with six sides covers (4), it and rotor block are fixed with screw attachment, hexagonal hole on its six sides cover (4) is corresponding with the hexahedron on the driving shaft (6), on six sides covers (4), be installed on core retainer plate bolt (3), screw thread and core retainer plate bolt (3) on the six sides covers (4) link, fan housing (7) be installed in rotor block (5) above, with the locking nut location, link with rotor block.
2. big capacity centrifuge rotor liftout attachment according to claim 1 is characterized in that going up central authorities at locking nut (2) and fan housing (7) is installed on fan housing lid (1), by locking nut (2) fixed rotor body.
