Description
Technical field
The utility model is related to jig Design field, more particularly to a kind of fixture for being used to clamp aluminium bar.
Background technology
In turning aluminium bar outer peripheral face, generally one end of aluminium bar is clamped using three-jaw chuck, the other end of aluminium bar is leaned on
Top support, but aluminium bar can not be carried out turning at the outer peripheral face of three-jaw chuck retaining part, being at this time accomplished by shutdown will
Aluminium bar removes again again reverse clamp and carries out turning, more bothers, wastes time and energy, production efficiency is relatively low, while top to aluminium bar
End face can be produced compared with deep taper hole, influence product quality.In addition, the applicability of three-jaw chuck is poor, when aluminium bar diameter is very big, lead to
It can not be clamped with scroll chuck.
Utility model content
The purpose of this utility model is that the defect for overcoming prior art to exist is used to clamp the fixture of aluminium bar there is provided a kind of,
Strong applicability and production efficiency can be greatly improved.
The utility model solves the technical scheme that its technical problem used：A kind of fixture for being used to clamp aluminium bar, bag
Include body, cylindricality clamping jaw, clamping jaw is slidably fixed in the through hole of body, and clamping jaw one end extend to body outside,
The other end is resisted against on the end face of adjustment plate, and one end of the adjustment plate opposite with clamping jaw and globe thrust bearing are engaged, clamping jaw
For two or more, the slip of clamping jaw drives the swing of adjustment plate, and globe thrust bearing is arranged in the neck of adpting flange, is connected
In flange is connected with body and adjustment plate, globe thrust bearing be wrapped in by the two.
Beneficial effect：Fixture of the present utility model is in use, two fixtures are one group, and the clamping jaw of two fixtures is born against
Clamping is realized on the two ends end face of aluminium bar, so turnery processing, process easily can be carried out to the outer peripheral face of aluminium bar
In without shut down adjustment aluminium bar, greatly improve production efficiency.In addition, the use of fixture is the folder to aluminium bar end face by clamping jaw
Hold, regardless of aluminium bar diameter, do not affect clamping of the clamping jaw to aluminium bar end face, clamping jaw simultaneously can be by adjustment plate certainly
Adapt to non-perpendicular end face so that fixture it is with strong applicability.

Embodiment
With reference to Fig. 1-Fig. 3, the utility model will be further described.
A kind of fixture for being used to clamp aluminium bar, including body 10, cylindricality clamping jaw 20, clamping jaw 20 are slidably fixed on body
In 10 through hole, and one end of clamping jaw 20 extends to the outside of body 10, the other end and is resisted against on the end face of adjustment plate 30, with folder
One end of the opposite adjustment plate 30 of pawl 20 and globe thrust bearing 40 are engaged, and clamping jaw 20 is two or more, the slip of clamping jaw 20
The swing of adjustment plate 30 is driven, globe thrust bearing 40 is arranged in the neck of adpting flange 50, adpting flange 50 and body 10
It is connected and in adjustment plate 30, globe thrust bearing 40 be wrapped in by the two.
Fixture of the present utility model is in use, two fixtures are one group, and fixture is fixed on lathe by adpting flange 50,
The clamping jaw 20 of two fixtures is born against realizes clamping, periphery that so can easily to aluminium bar on the two ends end face of aluminium bar
Face is carried out in turnery processing, process without shutting down adjustment aluminium bar, greatly improves production efficiency.In addition, the use of fixture is
Clamping by clamping jaw 20 to aluminium bar end face, regardless of aluminium bar diameter, does not affect folder of the clamping jaw 20 to aluminium bar end face
Hold so that fixture it is with strong applicability.In addition, because clamping jaw 20 is slidably fixed in body 10, one end of clamping jaw 20 against
On the end face of adjustment plate 30, and adjustment plate 30 and globe thrust bearing 40 are engaged, accordingly even when the end face of aluminium bar has necessarily
Gradient, itself extension elongation of clamping jaw 20 also can be adjusted freely, when one of clamping jaw 20 is retracted back, and this clamping jaw 20 gives adjustment plate 30
One power, adjustment plate 30 is rocked, and is driven another clamping jaw 20 to stretch out, is realized the adjustment of the extension elongation of clamping jaw 20, to adapt to aluminium bar
End face, it is ensured that the clamping to aluminium bar end face.
It is used as further preferred scheme：Spring 60, spring 60 are arranged between the end face and body 10 of the adjustment plate 30
Two ends be separately fixed in the groove of the groove of the end face of adjustment plate 30 and body 10, spring 60 be two or more.Spring 60
Stablizing relatively for body 10 and the position of adjustment plate 30 is realized, and does not influence rocking for adjustment plate 30.
Further, the adjustment plate 30 includes enlarged diameter section 31 and reduced diameter section 32, and one end of spring 60 is fixed on greatly
In the groove of the end face of diameter segment 31, reduced diameter section 32 and globe thrust bearing 40 are engaged.
It is preferred that, the side of the clamping jaw 20 opens up setting counterbore 11, the He of counterbore 11 on chute 21, the outer face of body 10
The through hole of the body 10 is connected, and is connected by screw on the bottom surface of counterbore 11 and is fixed with slide plate 70, and slide plate 70 is hung to this
In the through hole of body 10, and slide plate 70 and chute 21 coordinate and realize being slidably matched for clamping jaw 20 and body 10.
In order to ensure the firm of fixture clamping, the clamping jaw 20 is 6 and arranged along the end face circumferentially-spaced of body 10.
Further, the outer face of the body 10 middle part set dismounting screwed hole 12, facilitate fixture dismounting and
Carry.
It should be appreciated that specific embodiment described above is only used for explaining the utility model, it is not used to limit this reality
With new.The obvious changes or variations extended out by spirit of the present utility model is still in protection of the present utility model
Among scope.
