Abstract
The technical problem that processing efficiency is low, precision is not high when the utility model relates to a kind of reel processing tail frame devices to solve to process thin-walled long carriage using tail frame device in the prior art.Morse taper shank is mounted in chuck and bearing block by the common support rotating of first bearing and second bearing in the reel processing tail frame device of the utility model, the structure design of dual-gripper bearing increases the support stiffness to Morse taper shank, shakes knife phenomenon when advantageously reducing processing.Simultaneously, due to increasing the rigid bottom of support to Morse taper shank, the projecting end of Morse taper shank can be accomplished longer distance, when needing processing winding drum inner stopper in this case, after removing head end support, the tailstock installed on Morse taper shank projecting end be can extend into inside barrel diameter, expose the both ends of reel inner peripheral surface while roll support is risen, without adding centre frame, it is also not required to multiple clamping.It not only improves and improves processing efficiency, be conducive to improve machining accuracy again.
Description
Technical field
The utility model relates to a kind of reels to process tail frame device.
Background technique
At present when processing hub type reel, need to be supported reel from the axial ends of reel.The support knot of tail end
Structure is tail frame device, and tail frame device includes that the chuck being arranged on body, the Mohs being rotatably arranged on chuck by bearing are bored
Handle and the tailstock being sleeved on Morse taper shank, the tail end of reel are supported by the projecting end of tailstock.
But in the reel that processing wall is thin, length is long, it has been found that the prior art serious, noise in the presence of shake knife in processing
Greatly, the defect of processed surface smoothness difference.In the prior art there is also need multiple clamping be just able to achieve outer circle, rope groove and it is interior only
The technical issues of mouth processing.When processing inner stopper, since the support of head end needs to remove, need additionally to connect centre frame to volume
Cylinder is supported.So there are low efficiencys, inside and outside circle concentricity difference when the long reel of, length thin using prior art processing wall
Defect.
Utility model content
The purpose of this utility model is to provide a kind of reel processing tail frame devices to solve using tail in the prior art
The technical problem that processing efficiency is low, precision is not high when rack device processing thin-walled long carriage.
To achieve the above object, a kind of reel processing tail frame device of the utility model uses following technical scheme:
A kind of reel processes tail frame device, including chuck and Morse taper shank, and the chuck is towards Morse taper shank projecting end
First end is fixed with bearing block, and the first end of chuck is provided with the first counterbore for accommodating first bearing, and the second of bearing block
End is provided with the second counterbore for accommodating second bearing, and Morse taper shank is turned by the common support of first bearing and second bearing
Dynamic to be mounted in chuck and bearing block, the bottom hole of the first counterbore is formed keeps off for the chuck of block first bearing outer ring second end
Shoulder, the bottom hole of the second counterbore form the bearing block shoulder block for being used for block second bearing outer ring first end, are provided on Morse taper shank
Bearing shoulder block for block second bearing inner ring first end.
The diameter of first counterbore is identical as the diameter of the second counterbore, centerline collineation.
The depth of first counterbore is greater than the height of first bearing, is arranged with spacer on the outer peripheral surface of Morse taper shank, spacer is set
It sets between the inner ring of first bearing and the inner ring of second bearing to fill the axial gap between first bearing and second bearing.
Through bolt releasable connection on chuck, the bolt is sunk in chuck and bearing block the bearing block completely.
The second end of Morse taper shank is threaded section, is arranged with locking nut on thread segment, the end face of locking nut with
The second end block of first bearing inner ring cooperates.
The beneficial effects of the utility model are as follows: Morse taper shank passes through the in the reel of the utility model processing tail frame device
One bearing and the common support rotating of second bearing are mounted in chuck and bearing block, and the structure design of dual-gripper bearing increases
To the support stiffness of Morse taper shank, knife phenomenon is shaken when advantageously reducing processing.Simultaneously as increasing the support to Morse taper shank
The projecting end of Morse taper shank can be accomplished longer distance by rigid bottom, when needing processing winding drum inner stopper in this case, remove head end
After support, the tailstock installed on Morse taper shank projecting end be can extend into inside barrel diameter, by reel while roll support is risen
The both ends of inner peripheral surface are exposed, and without adding centre frame, are also not required to multiple clamping.It not only improves and improves processing efficiency, is conducive to again
Improve machining accuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of reel of the utility model processes one embodiment of tail frame device.
Specific embodiment
A kind of specific structure of reel processing tail frame device of the utility model is as shown in Figure 1, include chuck 1, bearing block
2, Morse taper shank 3, first bearing 4, second bearing 5, spacer 6, hexagon socket head cap screw 7 and locking nut 8.
In the application, each components are defined as first end close to one end of 3 projecting end of Morse taper shank, each components are remote
One end from Morse taper shank projecting end is defined as second end.
Bearing block 2 is fixed on first end of the chuck 1 towards 3 projecting end of Morse taper shank by hexagon socket head cap screw 7.Chuck 1
First end is provided with the first counterbore 11 for accommodating first bearing 4, and the second end of bearing block 2 is provided with for accommodating the second axis
5 the second counterbore 21 is held, first bearing 4 is mounted in the first counterbore 11 with being completely embedded into, and second bearing 5 is installed with being completely embedded into
In the second counterbore 21.Morse taper shank 3 is mounted on chuck 1 and axis by the common support rotating of first bearing 4 and second bearing 5
It holds in seat 2.The bottom hole of first counterbore 11 forms the chuck shoulder block 12 for being used for 4 outer ring second end of block first bearing, the second counterbore
21 bottom hole forms the bearing block shoulder block 22 for being used for 5 outer ring first end of block second bearing, is provided on Morse taper shank 3 for keeping off
The only bearing shoulder block 31 of 5 inner ring first end of second bearing.The second end of Morse taper shank 3 is threaded section, is arranged on thread segment
