Description
Technical field
The present invention relates to a kind of positioning fixture of valve flanges.
Background technology
, it is necessary to be fixed by fixture when to hole machined in valve progress or assembling, the clamping of valve generally needs
Valve body and the flange section of end are fixed by fixture, and existing flange clamping structure only has the effect of fixed clamping
Fruit, it is impossible to be neatly adjusted, the clamping angle of flange also needs to be adjusted by auxiliary tool, and the installation of fixture
It is more troublesome with dismounting, it is time-consuming and laborious.
The content of the invention
For above-mentioned technical problem, the purpose of the present invention is：Propose a kind of positioning fixture of valve flanges.
What the technical solution of the present invention was realized in：A kind of positioning fixture of valve flanges, comprising positioning plate, on
Holder and lower holder；Positioning pin is provided with the positioning plate；Work pieces mate portion is both provided with the upper holder and lower holder,
Upper holder is coordinated with lower holder by two vertical screw rods；One end of the upper holder is coordinated by through hole and a screw rod,
The other end is coordinated by open slot and another screw rod；It is provided with the upper holder and lower holder at least one of which vertical
Locating slot, locating slot are located at the middle in work pieces mate portion, and positioning plate coordinates with locating slot.
Preferably, rack is additionally provided with the upper holder, rack is used for placement positioning plate.
Preferably, the work pieces mate portion is V-shaped groove.
Due to the utilization of above-mentioned technical proposal, the present invention has following advantages compared with prior art：
The positioning fixture of the valve flanges of the present invention, can be used for the clamping of valve end flange, can be used for single method
The clamping of blue workpiece；Workpiece can realize the fast positioning of special angle by positioning plate；Upper holder passes through open slot and one
Screw rod coordinates, and holder is rotated around another screw rod, rides on built, easy to operation, overall structure is simple, user
Just, improve work efficiency.
Brief description of the drawings
Technical solution of the present invention is described further below in conjunction with the accompanying drawings：
Attached drawing 1 is a kind of schematic diagram of the positioning fixture of valve flanges of the present invention；
Attached drawing 2 is the schematic diagram of the positioning plate of the present invention.
Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
As shown in attached drawing 1-2, a kind of positioning fixture of valve flanges of the present invention, positioning plate 21,11 and of upper holder
Lower holder 12, upper holder 11 are coordinated by two vertical screw rods 13 with lower holder 12, are all provided with upper holder 11 and lower holder 12
Work pieces mate portion 5 is equipped with, work pieces mate portion 5 is V-shaped groove, and the middle of V-shaped groove is provided with vertical locating slot 15；The upper folder
One end of seat 11 is coordinated by through hole and a screw rod 13, and the other end is coordinated by open slot 14 and another screw rod 13, upper folder
The top of seat 11 is additionally provided with rack 16；Two positioning pins 22, positioning plate 21 and locating slot are provided with the positioning plate 21
15 coordinate, and two positioning pins 22 bolt hole opposite with two of flange workpiece coordinates.
During work, by two positioning pins 22 of positioning plate 21, mode is inserted on the bolt hole of flange as shown, adjusts flange
Positioning plate 21 is in vertical direction roughly, and flange workpiece is placed on the V-shaped groove of lower holder 12, be inserted into positioning plate 21
Holder 11 and locked in locating slot 15, in pressure, be positioned such that plate 21 is just completely in vertical direction, realize flange specific
The fast positioning of angle, can remove positioning plate 21 afterwards, and be placed on rack 16, to treat next use；It is clamping it
After flange or valve can be processed or assembled, if workpiece is valve, it is also necessary to the other parts of valve into luggage
Folder；After machining, holder 11 in release, can turn to opposite side by the one end of upper holder 11 with open slot 14, you can
Remove workpiece, it is not necessary to upper holder 11 is unloaded completely, simplifies operation, improves efficiency.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, it is all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all cover within the scope of the present invention.
