Description
Technical field
The utility model is related to a kind of circular shaft quick chuck.
Background technology
In circular shaft-type parts batch machining field, it is necessary to realize Quick-clamped and replacing to circular shaft, to ensure processing effect
Rate.Existing circular shaft fixed structure, is clamped to circular shaft and Renewal process is complicated, and operation inconvenience has had a strong impact on processing efficiency.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of circular shaft quick chuck, and circular shaft can be realized easily and fast
Clamping and replacing, to improve processing efficiency.
The utility model is solved the above problems by following technological means：A kind of circular shaft quick chuck, including sleeve, sleeve
Circumferentially it is evenly arranged with wall in three hole slots, the hole slot and is provided with round end roller, round end roller can not be from the bottom of hole slot
Drop out, in addition to the eccentric bushing that three round end rollers are entangled, the eccentric bushing inwall is circumferentially evenly arranged with three arc ditches,
Three arc ditches are respectively used to the corresponding round end roller of clamping, and eccentric bushing both sides are provided with end cap, and the end cap passes through locking
Screw is connected with eccentric bushing, and axially position is realized by back-up ring between end cap and sleeve.
Further, lubricating chamber is provided with the round end roller, the lubricating chamber passes through bellmouth and round end roller bottom
Plunger is provided with connection, the bellmouth, the plunger is connected by spring with lubrication chamber interior walls.
Further, the eccentric bushing outer wall section is regular hexagon.
The beneficial effects of the utility model：It is circumferential equal in circular shaft quick chuck of the present utility model, including sleeve, sleeve wall
Even be provided with three hole slots, the hole slot is provided with round end roller, and round end roller can not be dropped out from the bottom of hole slot, in addition to
The eccentric bushing that three round end rollers are entangled, the eccentric bushing inwall is circumferentially evenly arranged with three arc ditches, three arc ditches
The corresponding round end roller of clamping is respectively used to, eccentric bushing both sides are provided with end cap, and the end cap passes through lock-screw and bias
Set connection, axially position is realized between end cap and sleeve by back-up ring.The circular shaft quick chuck of the structure, can be real easily and fast
The clamping and replacing of existing circular shaft, so as to effectively increase processing efficiency.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A views；
Fig. 3 is the structural representation of round end roller.
Embodiment
The utility model is described in detail below with reference to accompanying drawing.As Figure 1-3, circular shaft of the present utility model is fast
Change circumferentially to be evenly arranged with chuck, including sleeve 1, sleeve wall in three hole slots 2, the hole slot and be provided with round end roller 3, circle
Head roller can not be dropped out from the bottom of hole slot, in addition to the eccentric bushing 4 that three round end rollers are entangled, and the eccentric bushing outer wall is cut
Face is regular hexagon, and eccentric bushing inwall is circumferentially evenly arranged with three arc ditches 5, and it is corresponding that three arc ditches are respectively used to clamping
Round end roller, eccentric bushing both sides are provided with end cap 6, and the end cap is connected by lock-screw 7 with eccentric bushing, end cap and sleeve
Between axially position is realized by back-up ring 8, back-up ring and sleeve clamping, end cap are fixedly connected with sleeve.During fixed circular shaft, by circular shaft
Insertion sleeve, by spanner drive eccentric bushing rotate, using round end roller compress circular shaft, finally by lock-screw by end cap with
Eccentric bushing is connected.When needing to change circular shaft, it is only necessary to unclamp lock-screw, rotate backward eccentric bushing, unclamp round end roller
Clamping to circular shaft.In summary, the circular shaft quick chuck of the structure, the clamping and more of circular shaft can be realized easily and fast
Change, so as to effectively increase processing efficiency.
As the further improvement to above-mentioned technical proposal, lubricating chamber 9, the lubricating chamber are provided with the round end roller
Connected by bellmouth 10 with round end roller bottom, be filled with lubricating chamber in lubricating oil, the bellmouth and be provided with plunger 11,
The plunger is connected by spring 12 with lubrication chamber interior walls.During circular shaft is clamped, circular shaft promotes plunger to lubricating chamber one
Side is moved, and makes outflow of lubrication oil, circular shaft surface is lubricated, be avoided that circular shaft surface is crushed by round end roller, when removing circle
After axle, spring promotes plunger return, continues to block bellmouth, it is to avoid outflow of lubrication oil.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
