Description
Technical field
The utility model relates to valve body field, particularly relates to a kind of high accuracy valve body self-positioning locking frock.
Background technology
The method of existing processing valve body lumen mainly contains two kinds: one adopts vertical machining centre processing, and another kind adopts horizontal Machining centers processing.
Use vertical machining centre is processed, and due to the unreasonable structure of positioning and locking device, is difficult to ensure, has a strong impact on valve body precision to its valve body two axis precision.
And use horizontal Machining centers to process, although can reach axis precision, its manufacturing cost is far longer than vertical machining centre.
Utility model content
The technical problem that the utility model mainly solves is: for the deficiencies in the prior art, provides a kind of high accuracy valve body self-positioning locking frock, can improve machining accuracy, reduce costs simultaneously.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of high accuracy valve body self-positioning locking frock, valve body is clamped for vertical machining centre, comprise: base plate, detent mechanism, supporting mechanism and fixed mechanism, described detent mechanism and supporting mechanism are fixed on described base plate, described valve body is fixed by described fixed mechanism and described detent mechanism, and is supported by described supporting mechanism.
In the utility model preferred embodiment, described detent mechanism comprises L-type location-plate and some triangular reinforcing plate, and described L-type location-plate is fixed on described base plate, and described triangular reinforcing plate has 2, is parallelly fixed on described L-type location-plate.
In the utility model preferred embodiment, described triangular reinforcing plate is fixed on described L-type location-plate by bolt and packing ring.
In the utility model preferred embodiment, described supporting mechanism is be fixed on the back-up block on described base plate, and described back-up block is V-shaped.
In the utility model preferred embodiment, described fixed mechanism comprises locating ring, screw rod and pressing plate, described valve body is arranged on described L-type location-plate by described screw rod, and stiff end is located by described locating ring, described pressing plate is fixed on the outer surface of described valve body, and by a nut check, and the below of described valve body is supported by described supporting mechanism.
In the utility model preferred embodiment, the fit clearance of described valve body and described L-type location-plate is less than or equal to 0.03mm.
In the utility model preferred embodiment, described base plate offers 4 locking holes fixed with vertical machining centre, lay respectively on four angles of described base plate.
The beneficial effects of the utility model are: be applied in vertical machining centre, the method of vertical machining centre processing valve body lumen is adopted to replace horizontal Machining centers processing method, by fixed mechanism, valve body is fixed on detent mechanism, and supported by supporting mechanism, can machining accuracy be improved, reduce costs simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high accuracy valve body of the utility model self-positioning locking frock;
In accompanying drawing, the mark of each parts is as follows: 1, base plate, and 11, locking hole, 21, L-type location-plate, 22, triangular reinforcing plate, 23, packing ring, 24, bolt, 31 back-up blocks, 41, locating ring, 42, screw rod, 43, pressing plate, 44, nut, 5, valve body.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1, the present embodiment comprises:
A kind of high accuracy valve body self-positioning locking frock, clamps valve body 5 for vertical machining centre, comprising: base plate 1, detent mechanism, supporting mechanism and fixed mechanism.
Described base plate 1 offers 4 locking holes 11 fixed with vertical machining centre, laying respectively on four angles of described base plate 1, by adopting the hexagon socket head cap screw of 4 M16 long 60, described high accuracy valve body self-positioning locking frock being locked on vertical machining centre table top.
Described detent mechanism comprises L-type location-plate 21 and some triangular reinforcing plate 22, described L-type location-plate 21 is fixed on described base plate 1, described triangular reinforcing plate 22 has 2, be fixed on described L-type location-plate 21 by bolt 24 is parallel with packing ring 23, for ensureing that L-type location-plate 21 can bear certain pressure and shock and indeformable.
Described supporting mechanism is be fixed on the back-up block 31 on described base plate 1, and described back-up block 31 is V-shaped
Described fixed mechanism comprises locating ring 41, screw rod 42 and pressing plate 43, described valve body 5 is arranged on described L-type location-plate 21 by described screw rod 42, and stiff end is located by described locating ring 41, described pressing plate 43 is fixed on the outer surface of described valve body 5, and locked by a nut 44, described nut 44 is hex nut, and the below of described valve body 5 is supported by described back-up block 31.
Described valve body 5 is less than or equal to 0.03mm with the fit clearance of described L-type location-plate 21.
Vertical machining centre adopts high accuracy valve body self-positioning locking frock fixed valve body of the present utility model, process, machine the size of rear inspection valve body working position, namely at the upper test valve body axis degree of three-dimensional (CMM), then antirust, packaging, warehouse-in are carried out to the valve body be up to the standards.
The method being installed additional high accuracy valve body self-positioning locking frock processing valve body lumen by vertical machining centre instead of horizontal Machining centers processing method, both machining accuracies are identical, processing cost at least reduces 1 times and (comprises equipment investment, the cost of charp tool), be mainly reflected in (the every platform of vertical machining centre equipment general 450,000-80 ten thousand, the every platform of horizontal Machining centers 1,200,000-280 ten thousand) in equipment cost.
