Background technology
One of critical pieces of gun such as optical sight is hunted as field, physical culture shooting, decide the accuracy of gun,
With very big market demand.Domestic optical sight manufacturing industry is developed so far, and its yield accounts for world optical gun sight product
The 70% of amount accounts for the half of the country of world's gun sight production.But China's optical sight product generally belongs to mid and low-end products, and
Versatility is relatively low.Known in the industry, domestic Ge Jia optical sights manufacturing enterprise is mainly former with " operation dispersion " when part is processed
Many universal machine tools, special purpose machine tool or Digit Control Machine Tools are then organized to automate or semi-automatic production line form is given birth to
Produce, it is necessary to larger initial investment and larger Operational preparation cycle, while needing more operating personnel, labour intensity
Greatly, it is impossible to which the polytropy of the order of enough appropriate products, production line can not carry out flexible adjustment, while also have impact on product quality
Further lifting, above-mentioned factor constrains the development of the industry.
Current optical sight shank processing, the fixture of use need to be operated manually, and not possess general applicability, therefore
It is badly in need of a kind of intelligent fixture that can be directed to the processing of complete series optical sight shank of research and development, comes improve production efficiency and matter
Amount, and reduces cost.This patent is a kind of optical sight shank Excircle machining special fixture, through retrieval, is not found and this hair
Bright same or analogous technical scheme.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of intelligent automation and efficient Unmanned operation environment, is capable of achieving
Automation positioning after optical sight shank body clamping clamps and releases clamping function, so that improve production efficiency, and drop
Low labour cost and intensity.
In order to solve the above technical problems, the technical scheme is that：A kind of optical sight shank Excircle machining is special
Fixture, including drag link mechanism, positioning tapered sleeve, auxiliary feel trim actuator, tensioner element, the first flexible member, support bar, the second elasticity
Element and top, drag link mechanism jockey and main shaft, tensioner element are arranged in positioning tapered sleeve, and the connection of tensioner element left end is auxiliary
Feel trim actuator is helped, tensioner element right-hand member connection support bar is provided with the first elastic component in positioning tapered sleeve outer right wall, support bar is right
The second elastic component is provided with the outer wall of end, support bar right end is connected with top.
Further, drawing mechanism is connected through a screw thread main shaft and support member, and is array of sizes, replaceable.
Further, auxiliary feel trim actuator is the one kind in Rectangular Spring, helical spring etc..
Further, support bar is array of sizes, and support bar possesses convertibility, is applicable to different series size work
Part.
Further, the first flexible member and the second flexible member are the one kind in the materials such as metal, rubber, resin.
Further, top is center special.
Beneficial effect：
A kind of above-mentioned optical sight shank Excircle machining special fixture, by drawing mechanism, realizes fixture and special purpose machine tool master
The connection of axle, and positioning is realized by positioning tapered sleeve, center special under external force, is moved axially, to workpiece and elasticity
Part produces axial thrust, while support bar produces axial thrust to elastic component, after workpiece is positioned, in A, the slope of B location
Under stressing conditions, flexible member produces sliding, dilatating and deformable, so as to clamp the two ends endoporus of gun sight in slope.Process
External force is removed after, is unloaded by aiding in feel trim actuator, the automatic reduction under elastic component elastic reaction releases Workpiece clamping
Effect.

Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages of the invention and effect easily.
As shown in figure 1, the invention discloses a kind of optical sight shank Excircle machining special fixture, including drag link mechanism
1st, positioning tapered sleeve 2, auxiliary feel trim actuator 3, tensioner element 4, the first flexible member 5, support bar 6, the second flexible member 8 and top
9, drag link mechanism jockey and main shaft；Tensioner element 4 is arranged in positioning tapered sleeve 2, the connection auxiliary unloading of the left end of tensioner element 4
Mechanism 3, the right-hand member connection support bar 6 of tensioner element 4；The first elastic component 5 is provided with the positioning outer right wall of tapered sleeve 2, support bar is right
End sets the second elastic component 8, and the right end of support bar 6 is connected with top 9.By drag link mechanism 1, fixture and special purpose machine tool are realized
