Abstract
The utility model relates to an assembled flexible coupling. The assembled flexible coupling comprises a chuck, a flexible sleeve and a spindle with a tip, wherein a slot is cut on the chuck; matched connection holes are respectively arranged at two sides of the slot; the flexible sleeve forms an H shape; a through hole is arranged in the middle of the flexible sleeve; a plurality of locating holes are arranged at one end of the flexible sleeve along the peripheral direction; one end of the flexible sleeve provided with the locating holes is connected with a spindle by virtue of a fastener, and the other end of the flexible sleeve is connected with the chuck by virtue of the fastener. The assembled flexible coupling has the advantages of small size, simple structure, and large transmit torque without a torsional return difference, can adapt to various specifications of core shafts, and can adapt to the usable ranges of a work-piece with large-diameter change and the core shafts.
Description
Technical field
The utility model relates to field of machining and machinebuilding technology, in particular for the made up flexible coupling that is connected between axle and the axle.
Background technique
Coupling is widely used in the transmission fields such as machinery, hydraulic pressure, be mainly used in being connected between axle and the axle, generally speaking, owing to reasons such as working machine tool and manufacture costs, usually transmit between the diaxon with coupling and rotatablely move, thereby realize connecting two axles in the different institutions, make it jointly to rotate with transmitting torque, and in the power transmission of high-speed overload, playing buffering, damping and raising axle is the effect of dynamic performance.
In the prior art, when using mandrel clamping gear grinding, traditional structure adopts workpiece head, tailstock center to head on respectively the center hole at mandrel two ends, carries out centralized positioning, adopts simultaneously driving lever, shifting fork structure to carry out transmission of torque.The shortcoming of conventional construction is: 1, can only bear unidirectional torque when driving lever, shift fork do not connect firmly; 2, the malalignment because of work spindle axis and the top on line of head, tail frame can produce the moment of flexure interference when driving lever, shift fork connect firmly, thus the indexing accuracy when affecting gear grinding; 3, driving lever, the phase place of gear is accurately located.
The model utility content
The applicant provides made up flexible coupling a kind of rational in infrastructure, easy for installation, thereby can connect the diaxon transmitting torque for these shortcomings in the above-mentioned existing production, can play certralizing ability again, and is flexible and convenient to use.
The technological scheme that the utility model adopts is as follows:
A kind of made up flexible coupling comprises chuck, flexible boot and with top main shaft, and described chuck has been cut the line of rabbet joint, is positioned at line of rabbet joint both sides and has the attachment hole that matches; Described flexible boot becomes I-shaped, has through hole in the middle of the described flexible boot, and an end of described flexible boot has a plurality of positioning holes along circumferencial direction; Described flexible boot has positioning hole one end and is connected by fastening piece with main shaft, the other end be connected with chuck by fastening piece.Its further technological scheme is:
Outer peripheral surface is along axially being evenly distributed with the interlaced 90 ° line of rabbet joint of many groups in the middle of the described flexible boot, and described line of rabbet joint axial displacement span cuts to diameter from cylindrical.
The beneficial effects of the utility model are as follows:
The utlity model has that size is little, simple in structure, transmitting torque is large, without reversing return difference, can adapting to the advantage such as plurality of specifications mandrel, can adapt to than the workpiece of larger diameter variation and the using scope of mandrel.
The made up flexible coupling is mainly assembled by flexible boot and link chuck, one end of flexible boot is connected with the work spindle end face, the other end is connected with chuck, because many lines of rabbet joint being set in the middle of the flexible boot, increase its flex capability, compare with traditional shaft coupling mode, clamping workpiece efficient improves more than 3 times; Transmission stiffness improves more than 2 times; The mandrel Location accuracy is brought up to more than the 0.005mm from 0.01mm, changes the chuck of different-diameter, can adapt to the mandrel of respective diameters.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As depicted in figs. 1 and 2, made up flexible coupling described in the utility model, comprise chuck 2, flexible boot 3 and with top main shaft 5, the line of rabbet joint has been cut in chuck 2 bottoms, the left and right sides that is positioned at the line of rabbet joint is respectively arranged with bolt hole 8 in mating connection, and chuck 2 one ends have bolt hole 9 along circumferencial direction; 3 one-tenth of flexible boot are I-shaped, have through hole in the middle of the flexible boot 3, see Fig. 3 and Fig. 4, outer peripheral surface is along axially being evenly distributed with one group of interlaced line of rabbet joint of 90 ° 9 in the middle of the flexible boot 3, every the suitable distance of line of rabbet joint axial displacement is cut to diameter from cylindrical, the line of rabbet joint that can not count on the same group according to required flexible setting; See Fig. 1, one end of flexible boot 3 has six positioning holes 7 along circumferencial direction, the end that flexible boot 3 has a positioning hole 7 is connected by the tapped hole 6 of opening on bolt 4 and the main shaft 5, and flexible boot 3 the other ends are connected with chuck 2, and is bolted to connection (among the figure for drawing).
In the actual using process, because flexible boot 3 is provided with slot, make coupling have preferably flex capability, in rotary course, then produced flexible effect, can compensate radially, angle, axial deviation; When the mandrel 1 of required processing is installed, behind the center and top contraposition with mandrel 1, again chuck 2 is placed on the mandrel, be bolted on flexible boot 3, and construction bolt locking in chuck 2 bolts hole that open the bottom 8, flexible boot 3 is connected with mandrel 1, makes flexible boot 3 can be with moving mandrel's 1 rotation; Along with the different chuck of the vary in diameter replaceable of mandrel, flexible and convenient to use.The utility model assembling is simple, and can not only make again can be fast without the transmission of carrying out torque of moment of flexure when workpiece is top feels relieved contraposition with the mandrel center hole, and cost is low.
Above description is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
