Technical field
The utility model relates to machine tools, particularly a kind of gas flow meter end cap numerically controlled lathe frock.
Background technology
Gas flow meter is a kind of application gas measurement device very widely.Its structure is generally two bowl-type end caps and is loaded into a shell relatively, and devices such as gage probe are installed by portion within it.The end cap result is as shown in Fig. 1-3, and the edge of end cap main body 2 is shaped on edge fit 1, and end cap bottom surface 4 is shaped on into and out of pore 5, sensor installing hole 6 and eccentric navel 3.Because the measured fluid of gas flow meter is a kind of toxic gas, therefore need end cap in follow-up installation and use, to have high sealing, to guarantee coal gas transmission and the security of using.Thus, in the process of end cap, guarantee that machining accuracy then becomes to attach most importance to.Particularly end cap is to the inner face 8 of edge fit; 9 places, rim of the mouth of end cap; Eccentric navel of end cap bottom surface and bottom surface made ring platform shape.
Existing end cap processing mode normally adopts die casting mode molded blank spare, by numerically controlled lathe or engine lathe fine finishining is carried out on end cap butt joint limit and end cap bottom surface again.When adopting lathe that blank is carried out fine finishining, need to guarantee the concentric steadily rotation of blank and lathe spindle.At present, need to adopt slowly centering of chuck or floral disc, it too much depends on operating personnel's experience and qualification, can't well realize turning to eccentric navel in end cap bottom surface, not only time-consuming, efficient is low, and machining accuracy is poor, product percent of pass is low, is unsuitable for the production in enormous quantities of part.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, but provide a kind of quick-clamping workpiece easy and simple to handle, and can guarantee that to be processed pivot of workpiece is concentric with lathe spindle, thereby improve the gas flow meter end cap numerically controlled lathe frock of workpiece machining accuracy and working (machining) efficiency.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of gas flow meter end cap numerically controlled lathe frock, it is characterized in that: constitute by first frock and second frock, first frock comprises a disc-shaped body, upper surface in this disc-shaped body is shaped on eccentric annular groove, near the outer edge circle distribution three alignment pins are installed at the upper surface of disc-shaped body, one hold-down bolt are installed at the upper surface of disc-shaped body; Second frock comprises a disc-shaped body, upper surface in this disc-shaped body is shaped on concentric round platform, be fixed with two alignment pins in this round platform outside symmetry, 4-6 bolt be installed in that the round platform periphery is uniform, on this bolt, all be set with slidably pressing plate, be shaped on eccentric round platform at the lower surface of disc-shaped body.
And the alignment pin on described first frock rivets the upper surface in disc-shaped body.
Advantage of the present utility model and beneficial effect are:
This gas flow meter end cap numerically controlled lathe frock, scientific structure design is reasonable, easy and simple to handle, can realize fast and stable clamping to the gas flow meter end cap, solve the eccentricity issues in the end cap fine finishining process simultaneously, guaranteed the machining accuracy of finished product, had the working (machining) efficiency height, the qualification rate advantages of higher is suitable for processing in enormous quantities.

The specific embodiment
The utility model is described in further detail below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of gas flow meter end cap numerically controlled lathe frock, the clamping when being used for numerically controlled lathe or engine lathe gas flow meter end cap blank being carried out the fine finishining of car pin.The structure of gas flow meter end cap as Figure 1-3, end cap be the bowl type, the rim of a bowl place of end cap main body 2 is shaped on edge fit 1, end cap bottom surface 4 is shaped on into and out of pore 5, sensor installing hole 6 and eccentric navel 3, the end cap lower body part is shaped on the groove 7 of two symmetries.The structure of this end cap is a prior art, and each made parts are its existing self structure on it, repeat no more.
The innovation part of this gas flow meter end cap numerically controlled lathe frock is: this frock is made of first frock and second frock.First frock comprises a disc-shaped body 10, is shaped on eccentric annular groove 12 at the upper surface of this disc-shaped body, made navel position, the corresponding gas flow meter end cap bottom surface of this off-centre annular groove.Upper surface in disc-shaped body is equipped with three alignment pins 11 near the outer edge circle distribution, comprise two that one at top and bottom symmetry also is close in these three alignment pins, alignment pin all rivets the outer surface in disc-shaped body, top that can be positioned the end cap main body, the top of these three alignment pins, two of bottoms can be positioned the made groove of end cap lower body part.Upper surface in disc-shaped body is equipped with a hold-down bolt 13, is used to install be positioned the made sensor installing hole of end cap.
Second frock comprises a disc-shaped body 14, is shaped on concentric round platform 15 at the upper surface of this disc-shaped body, the rim of a bowl place of this concentric round platform positioning end lid main body.Be fixed with two alignment pins 18 in this round platform outside symmetry.4-6 bolt 16 be installed in that the round platform periphery is uniform, on this bolt, all be set with slidably pressing plate 17, slidably pressing plate be used to press-fit the location end cap made to edge fit.Lower surface in disc-shaped body is shaped on eccentric round platform 19, is used to be clamped in the chuck of lathe.
The occupation mode of this frock is:
First frock is used to process the inner face 8 and 9 places, rim of the mouth to edge fit of end cap, as shown in Figure 3.Concrete occupation mode is: eccentric navel of end cap blank is positioned on the eccentric annular groove of frock upper surface, and the end cap main body is installed in three alignment pin inside, and hold-down bolt is threaded onto in the made sensor installing hole in end cap bottom surface, and compresses the location.Realize the concentric reliable location of end cap and frock thus.The disc-shaped body of first frock is installed in the scroll chuck that spindle of numerical control lathe drives, can carries out turning processing.
Second frock is used to process made eccentric navel on end cap bottom surface and the bottom surface.Concrete occupation mode is: to the disc-shaped body upper surface of edge fit spiral-lock in second frock, adopt four pressing plates with end cap edge fit is compressed the end cap blank, adopt two alignment pins location.Fix by the made eccentric round platform of disc-shaped body lower surface and the scroll chuck of numerically controlled lathe.Thus, realization end cap bottom surface and last made eccentric navel thereof are concentric with car dress main shaft, can carry out turning processing.
Can realize the turning processing on the two sides of gas flow meter end cap by above-mentioned two steps, this cover frock is based on the peculiar profile of gas flow meter end cap and is custom-designed, it is fast and reliable to have clamping, advantage of high production efficiency is used for the production efficiency that numerically controlled lathe and engine lathe can improve 50 times and 30 times respectively; And, the machining accuracy height, the product percent of pass height is suitable for the production in enormous quantities of part.
