Abstract

The utility model provides a box-type workpiece overturning fixture. The box-type workpiece overturning fixture comprises a ring-shaped fixture, wherein the shape of an inner ring of the ring-shaped fixture is the same as that of the cross section of a to-be-overturned workpiece, the size of the inner ring of the ring-shaped fixture is more than that of the cross section of the to-be-overturned workpiece. The exterior of the ring-shaped fixture is in the shape of a polygon. A plurality of eccentric lifting holes are formed in the cross section of the ring-shaped fixture. The box-type workpiece overturning fixture has the beneficial effects of simple structure and convenience for operation; the quality of a product is guaranteed; due to the adoption of the fixture, not only can the box-type workpiece be overturned, but also different overturning fixtures can be selected according to different overturning angles needed in actual productions.

Description

A kind of box workpiece turning frock

Technical field

The utility model relates to field of machining, relates in particular to a kind of box workpiece turning frock.

Background technology

In field of machining, some box workpiece need to carry out often more than one, mach surface, equally also need to parts be installed on a plurality of surfaces of box workpiece, therefore when box workpiece is processed and assembled, need to overturn to it, conversion placement location.The methods that adopt are with driving, framework to be converted the operation of placement location more at present, and this method has increased the work capacity of driving driver handling, has reduced work efficiency, also has certain danger simultaneously.

Utility model content

For overcoming the deficiencies in the prior art, this use is novel provides a kind of box workpiece turning frock.

The technical scheme that the utility model solves the employing of prior art problem is: a kind of box workpiece turning frock, comprise an annular frock, in described annular frock, loop-shaped is identical with the shape of cross section of workpiece to be flipped, and annular frock inner ring size is greater than workpiece cross section size to be flipped.Described annular frock outer shape is polygon.On described annular frock cross-sectional plane, there are a plurality of eccentric lifting hole(eyelet)s.

The beneficial effect of this utility model is: simple in structure, easy to operate, guarantee product design, and not only can overturn to box workpiece, and can be according to the different upset frock of angle Selection of needs of production upset.

The specific embodiment

For clearer, understand the purpose of this utility model, feature and advantage, below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail, but protection domain of the present utility model is not limited to following embodiment.

Be the first embodiment of the present utility model as shown in Figure 1 and Figure 2, comprise an annular frock 1 of square, on described annular frock 1 cross-sectional plane, have a plurality of eccentric lifting hole(eyelet)s 2.

Be the second embodiment of the present utility model as shown in Figure 3, Figure 4, comprise a regular hexagon annular frock 11, on described annular frock 11 cross-sectional planes, have a plurality of eccentric lifting hole(eyelet)s 22.

When box workpiece is overturn, first select the annular upset frock (1 close with box workpiece oad, 11), selection needs the size of the angle of upset again, for the first embodiment, workpiece can turn over and turn 90 degrees at every turn, for the second embodiment, and workpiece 60 degree that can at every turn overturn.Annular is overturn to tooling sleeve at the two ends of box workpiece to be flipped, crown block hook is hung in the lifting hole(eyelet) (2,22) of arranged off-centre, upwards pull crown block hook can complete the upset to box workpiece.

Preferably, when selecting embodiment, should fully take into account the axial center of gravity of box workpiece and the angle that at every turn needs upset.

It should be noted that, embodiment of the present utility model is not limited to above two kinds, and its outer shape is also not limited to square and regular hexagon, can be equilateral triangle, pentagon or other polygons.

Claims

1. a box workpiece turning frock, comprises an annular frock, it is characterized in that: in described annular frock, loop-shaped is identical with the shape of cross section of workpiece to be flipped, and annular frock inner ring size is greater than workpiece cross section size to be flipped; Described annular frock outer shape is polygon; On described annular frock cross-sectional plane, there are a plurality of eccentric lifting hole(eyelet)s.
