Description
Technical field
This utility model relates to a kind of frock, particularly relates to a kind of turning attachment.
Background technology
Fixture is to be used for fixing processing object during machine-building, is allowed to occupy correct position, to accept construction or inspection
The device surveyed, also known as fixture.In a broad sense, any operation in technical process, it is used for rapid, convenient, safety
The device of workpiece is installed on ground, all can be described as fixture.The most common weld jig, inspection jig, assembling jig, lathe
Fixture etc..
Conventional fixture can only press from both sides diameter workpiece in the least scope, if fixture is less with absorption surface area, is only capable of folder
Hold small diameter workpiece, during clamping large-diameter workpiece otherwise clamping incessantly, or the excessive defective work piece of pressure；If fixture and work
Part contact area is relatively big is then only capable of clamping large-diameter workpiece, and during clamping small workpiece, top is mutually collided.Additionally, the folder of routine
Only clamp sidewall during tool clamping workpiece, cannot fix in other directions, cause the location of workpiece the most firm.
Summary of the invention
This utility model provides a kind of turning attachment for solving above-mentioned technical problem.
Technical solution adopted in the utility model is: a kind of turning attachment, is fixed on working base including working base, one end
On fixing sleeve, through the grip bolt for clamping workpiece of fixing sleeve lateral wall；Described fixing sleeve cross section is in just
Hexagon, is equipped with, in the middle of 6 sidewalls, the internal thread hole coordinated with described grip bolt；Axle is passed through at described grip bolt top
Hold and connect the pressing plate having cross section curved；Described grip bolt includes 3 stay bolts and 3 lag bolts；Described stay bolt
Spaced apart with lag bolt.When diameter of work is less, using 3 stay bolt clampings, now arc half installed by stay bolt
The pressing plate that footpath is less；When diameter of work is medium, using 3 lag bolt clampings, it is bigger that arc radius installed by lag bolt
Pressing plate, increases contact area；When diameter of work is bigger, 6 grip bolts are used together, and increase stress point, increase total
Body lifting surface area, it is to avoid the excessive defective work piece of pressure.This utility model turning attachment can be suitable for the folder of different-diameter workpiece
Hold, simple in construction, easy to use.
As further improving, the pressing plate on described stay bolt top is movable pressing board；Described movable pressing board includes with described
The pressing plate seat that stay bolt is connected by bearing and the movable pressing board block being detachably connected on described pressing plate seat.When workpiece is straight
During the less only use stay bolt clamping of footpath, pressing plate seat is installed the movable pressing board block that arc radius is less；Work as diameter of work
When big stay bolt lag bolt clamps jointly, pressing plate seat is installed the movable pressing board block that arc radius is bigger, increases stress surface
Long-pending, reduce pressure, it is to avoid defective work piece.
As further improving, described pressing plate seat both sides are provided with groove；Described movable pressing board block is provided with recessed with described
The card base of slot fit.The installing/dismounting of movable pressing board block is the most convenient and swift.
As further improving, in the middle part of described fixing sleeve, it is provided with thickening layer.
As further improving, described working base center is provided with sucker chamber, and described sucker intracavity is provided with vacuum cup,
Described vacuum cup is by being connected through the trachea of described working base and a vacuum generator.Vacuum cup sucks workpiece end face,
Grip bolt clamping side so that the location of workpiece is more firm.
This utility model has the advantage that with good effect: owing to this utility model uses as above technical scheme, work as workpiece
When diameter is less, using 3 stay bolt clampings, now the pressing plate that arc radius is less installed by stay bolt；Work as diameter of work
Time medium, using 3 lag bolt clampings, lag bolt is installed the pressing plate that arc radius is bigger, is increased contact area；Work as work
When part is relatively large in diameter, 6 grip bolts are used together, and increase stress point, increase overall lifting surface area, it is to avoid pressure is excessive
Defective work piece.This utility model turning attachment can be suitable for the clamping of different-diameter workpiece, and simple in construction is easy to use.
Except this utility model described above solves the technical problem that, constitutes the technical characteristic of technical scheme and by this
Outside the advantage that the technical characteristic of a little technical schemes is brought, other technologies problem that this utility model can solve, technology
The advantage that the other technologies feature comprised in scheme and these technical characteristics are brought, hereinafter in conjunction with accompanying drawing make into
One step detailed description.
Accompanying drawing explanation
Structural representation when Fig. 1 is this utility model turning attachment holding smaller diameter workpiece；
Structural representation when Fig. 2 is this utility model turning attachment clamping larger diameter workpiece.
In figure: 1, working base；2, fixing sleeve；3, thickening layer；4, pressing plate；5, stay bolt；6, lag bolt；7、
Pressing plate seat；8, movable pressing board block.
Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
As depicted in figs. 1 and 2, the present embodiment is a kind of turning attachment, is fixed on working base 1 including working base 1, one end
On fixing sleeve 2, through the grip bolt for clamping workpiece of fixing sleeve 2 sidewall；Described fixing sleeve 2 cross section
In regular hexagon, it is equipped with, in the middle of 6 sidewalls, the internal thread hole coordinated with described grip bolt；In the middle part of described fixing sleeve 2
It is provided with thickening layer 3；Described grip bolt top connects the pressing plate 4 having cross section curved by bearing；Described grip bolt bag
Include 3 stay bolts 5 and 3 lag bolts 6；Described stay bolt 5 and lag bolt 6 are spaced apart.
Described working base 1 center is provided with sucker chamber, and described sucker intracavity is provided with vacuum cup, and described vacuum cup is by wearing
