Description
Technical field
This utility model belongs to hole machined technical field, and in particular to a kind of fixed dress for boring threeway flange screw hole
Put.
Background technology
Threeway flange, its equally distributed screw hole have clear and definite positional precision to want with the middle blank hole with skewed slot
Ask.In process of production, generally all it is the fixed positioning piece loaded onto of recruitment to shape in part（Blank hole with skewed slot）Carry out
Positioning, however but because of following three aspect the reason for, often there is workpiece and install not enter frock or the excessive problem of post gap is installed in Jing：
（1）The interior shape surface of part is black skin, does not require machining, and cast blank face overall accuracy is relatively low；（2）Different batches zero
Between part, deviation is larger；（3）Requirement of the different clients to shape size in the part is otherwise varied.
The content of the invention
For the drawbacks described above for overcoming prior art to exist, the purpose of this utility model is, there is provided one kind is used for
The fixing device in threeway flange screw hole is bored, prior art Jing when threeway flange screw hole is processed is solved and workpiece installation is often occurred
Do not enter frock or the excessive problem of post gap is installed.
The fixing device for boring threeway flange screw hole that this utility model is provided, it is by upper and lower two parts by circle
Pin is constituted together with mode connects for screw, and the top point includes bushing plate, renewable bushing, hand cradle, and the bottom point is including fixed
Position body, locating piece, the locating piece include radial positioning block and circumferentially positioned piece.The renewable bushing has several, leads to respectively
Cross screw to be fixed on bushing plate, the hand cradle is provided with two, be separately fixed at bushing plate both sides；The positioning body is provided with radially
Locating slot and circumferentially positioned groove, the radial positioning block are provided with four, are separately fixed in the radial detents of positioning body, described
Circumferentially positioned piece is fixed in the circumferentially positioned groove of positioning body.
The fixing device for boring threeway flange screw hole that this utility model is provided, its advantage is, by can
Adjust locating piece that radial positioning and circumferentially positioned is carried out to threeway flange, it is ensured that the requirement of precision, while it is big to position adjusting range,
Highly versatile, hand cradle also increase practicality.

Specific embodiment
With reference to the accompanying drawings, with reference to one embodiment, this utility model is provided for boring threeway flange screw hole
Fixing device is described in detail.
Embodiment
Referring to the drawings, the fixing device for boring threeway flange screw hole of the present embodiment, it is passed through by upper and lower two parts
Straight pin 4 is constituted together with mode connects for screw, and the top point includes bushing plate 1, renewable bushing 2, hand cradle 3, the lower part
Including positioning body 6, locating piece, the locating piece includes radial positioning block 5 and circumferentially positioned piece 9.The bushing plate 1 and positioning body
6 are connected with screw, straight pin 4, it is ensured that position relationship between the two；The renewable bushing 2 has eight, uniform by screw respectively
It is fixed on bushing plate 1, the hand cradle 3 is provided with two, is separately fixed at 1 both sides of bushing plate；The positioning body 6 is provided with radially fixed
Position groove 10 and circumferentially positioned groove 11, the radial positioning block 5 are provided with four, are separately fixed at the radial detents 10 of positioning body 6
Interior, described circumferentially positioned piece 9 is fixed in the circumferentially positioned groove of positioning body 11.
The fixing device for boring threeway flange screw hole of the present embodiment, its method for using：First take a sample test out with a collection of
In secondary threeway flange, its interstitial hole is smallest size of.Four pieces of radial positioning blocks 5 of frock are adjusted again, are allowed to lean out outside positioning body 6
The distance of disc is identical, and ensures the cylindrical centre with minimum in threeway flange of positioning that four pieces of radial positioning blocks 5 are collectively forming
Hole coordinates into the gap of 0.15mm, afterwards by threeway flange buckle in frock.Circumferentially positioned groove 11 along positioning body 6 adjusts week again
To the position of locating piece 9, make circumferentially positioned piece 9 and the skewed slot of threeway flange mesopore also coordinates into the gap of 0.15mm.In turn,
Under, frock is first tightened to screw rod 7 on T-shaped piece be mounted in Drilling machines bench T-slot, refills upper gasket 8 upper workpiece,
All-metal hexagonal flange locking nut is tightened, frock and threeway flange are fixed on Drilling machines bench.Finally, in interchangeable brill
Under the guiding of set 2, the drilling processing of 8 × Φ of threeway flange, 18 screw holes is completed.
