Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing 1-4.
By Fig. 1 to Fig. 4 it is found that a kind of thin-walled aluminum shape extrusion mandrel support device, including mandrel 1,1 screw thread of mandrel
It is connected on fixing piece 2, cavity 3 is equipped with inside mandrel 1, be equipped with a polygon prism 4 in cavity 3, along vertical axis direction on mandrel 1
Sliding is equipped with multiple fixed pins 5, and 5 inner end of fixed pin is contacted with polygon prism 4, and the rotation control fixed pin 5 of polygon prism 4 stretches, Gu
Determine to be equipped with the turntable 6 being fixedly connected with polygon prism 4 in part 2, offers handle hole 7 on fixing piece 2,2 inner wall of fixing piece is equipped with
With the lockable mechanism for turning connection.
The polygon prism 4 is triangular prism, the corner angle rounded corner of triangular prism.
The mandrel 1 is equipped with the limiting slot 8 positioned at 5 side of fixed pin, is extended on fixed pin 5 positioned at limiting slot 8
Interior baffle ring 9 is socketed with the first spring 10 in limiting slot 8 on fixed pin 5, and 10 both ends of the first spring are respectively held against baffle ring
9 and mandrel 1, the first spring 10 pushes fixed pin 5 to 1 internal direction of mandrel.
5 outer end of fixed pin is arc surface, and 5 inner end of fixed pin is equipped with chamfering.
The lockable mechanism includes the jam plate 11 being rotatably connected on 2 inner wall of fixing piece, 11 movable end of jam plate and turntable 6
The contact surface of contact, jam plate 11 and turntable 6 is frosting, and 11 movable end of jam plate connects through second spring 12 and 2 inner wall of fixing piece
It connects, jam plate 11 is pressed to turntable 6 by second spring 12.
The operating stick 13 being located in handle hole 7 is equipped with above the turntable 6.
When the utility model is used,
By 1 bottom of mandrel with being threadedly secured on fixing piece 2, the cavity 3 of mandrel 1 puts on polygon prism 4, initial position
When, the axis of fixed pin 5 is vertical with the seamed edge of polygon prism 4, at this point, the outer end of fixed pin 5 is located inside mandrel 1, does not stretch out core
1 outside of axis.
At this point, the thin-walled aluminium section processed will be needed to cover in 1 outside of mandrel, stayed between mandrel 1 and thin-walled aluminium section
There is gap, operating stick 13 is controlled by handle hole 7 at this time, turntable 6 is rotated, the rotation of polygon prism 4 pushes the cunning of fixed pin 5
Dynamic, fixed pin 5 is protruding to withstand the inner wall for needing fixed thin-walled aluminium section, in order to avoid damaging thin-walled aluminium section,
One layer of rubber pad can be added in the outer end of fixed pin 5, buffer the interaction force between fixed pin 5 and thin-walled aluminium section.
When using the present apparatus, the selection of 1 outer diameter of mandrel is slightly less than thin-walled aluminium section internal diameter so that it is convenient to thin-walled aluminium section
Placement, then fixed using fixed pin 5, so compared with the existing technology in interference fit want enhanced convenience to install,
And thin-walled aluminium section will not be destroyed.
In fixed thin-walled aluminium section, the rotation of polygon prism 4 pushes the sliding of fixed pin 5, so that fixed pin 5 is to mandrel
1 outside is mobile, and thin-walled aluminium section is fixed, and after completion of processing, and polygon prism 4 playbacks, and the first spring 10 is by fixed pin 5
It pushes inside to mandrel 1, so that fixed pin 5 is detached from thin-walled aluminium section, thin-walled aluminium section is smoothly removed.
Fixed pin 5 is movable in the limits of limiting slot 8, and the first spring 10 controls the reset of fixed pin 5 and guarantees solid
The position of rationed marketing 5.
The lockable mechanism of control turntable 6 is equipped in fixing piece 2, lockable mechanism includes jam plate 11 and second spring 12, jam plate
11 movable ends are contacted with turntable 6, at this point, jam plate 11 and 6 shape of turntable are at a certain angle, and are mill between jam plate 11 and turntable 6
Jam plate 11 is pressed on turntable 6 by sand face, second spring 12, so that turntable 6 contacts always with jam plate 11, when turntable 6 turns clockwise
When dynamic, frictional force pushes jam plate 11 to rotate, compressed spring, comes so that being separated between jam plate 11 and turntable 6, and turntable 6 smoothly turns
Dynamic, when turntable 6 rotates counterclockwise, jam plate 11 is tightly pressed against on turntable 6 by second spring 12, between turntable 6 and jam plate 11
Frictional force rotate turntable 6 can not, to play the role of locking, i.e., turntable 6 can not be made to reverse by polygon prism 4.
When processing, jam plate 11 is stirred out of handle hole 7, so that jam plate 11 and turntable 6 are detached from, rotates turntable 6 at this time,
So that fixed pin 5 recycles, thin-walled aluminium section can be smoothly removed.
The utility model compared with prior art, has the advantages that
1) interference fit is not used, and thin-walled aluminium section can quickly be inserted in mandrel 1, and avoid damage thin-walled aluminum type
Material；
2) fixed thin-walled aluminium section is convenient, and rotation turntable 6, can be by fixed pin 5 and thin-walled to the position not being able to rotate
Aluminium section locking, unclamping hand will not unclamp, and the presence of lockable mechanism can prevent in process, and external force is to fixed pin
The phenomenon that 5 effect makes it push polygon prism 4 and then reverses turntable 6, guarantee the stability of 5 position of fixed pin；
3) when removing, the jam plate 11 of lockable mechanism is stirred, the first spring 10 inwardly pushes fixed pin 5, so that turntable 6
It reverses, since jam plate 11 has been not present, so the first spring 10 can play the role of reset.
The utility model structure novel, it is easy to use, the fixation of thin-walled aluminium section can be quickly finished, and processing
The retraction of fixed pin 5 can be prevented in the process, guarantees the stabilization of thin-walled aluminium section in process, promote processing quality.
