Description

A kind of reel processing tail frame device

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 There is locking nut 8, the end face of locking nut 8 and the second end block of 4 inner ring of first bearing cooperate.By above structure by Mohs Taper shank axial direction Anti-moving is circumferentially rotatably mounted on chuck 1 and bearing block 2.

First bearing 4 is mounted in the first counterbore 11 with being completely embedded into, and it is heavy that second bearing 5 is mounted on second with being completely embedded into Structure design in hole 21 is completely isolated by first bearing 4 and second bearing 5, the assembly and disassembly of first bearing 4 and chuck 1, the The assembly and disassembly of two bearings 5 and bearing block 2 are independent of each other.

In the present embodiment, the diameter of the first counterbore 11 is identical as the diameter of the second counterbore 21, centerline collineation.In other realities It applies in example, the diameter of the first counterbore 11 and the second counterbore 21 can also be different, as long as guaranteeing that the two center line is identical.

In the present embodiment, the depth of the first counterbore 11 is greater than the height of first bearing 4, covers on the outer peripheral surface of Morse taper shank 3 Equipped with spacer 6, spacer 6 is arranged between the inner ring of first bearing 4 and the inner ring of second bearing 5 to fill first bearing 4 and Axial gap between two bearings 5.This structure design is ensured in the case where guaranteeing that chuck 1 and bearing block 2 are completely embedded The isolation of first bearing 4 and second bearing 5.

For the bearing block 2 through 7 releasable connection of hexagon socket head cap screw on chuck, the hexagon socket head cap screw 7 sinks to card completely In disk 1 and bearing block 2.In other embodiments, hexagon socket head cap screw can also be by manifold bolt or the bolt generation of other forms It replaces, as long as it can sink to chuck and bearing block completely；Locking nut 8 can also being capable of axial block first axle by others The stop part for holding 11 inner rings replaces, as long as making stop part releasable connection in the second end of Morse taper shank 3.
