Abstract
The utility model discloses a novel diameter-variable screwing mechanism, which is simple and practical, can realize the size adjusting in the circumferential diameter direction, and solves the problem of universality of screwing tools for screwing work of circumferentially uniformly distributed bolts in the industries such as automobile. The mechanism has a plurality of triangular compound connection rod structures and a plurality of rhomboid compound connection rod structures; one end of the oblige edge in each group of triangular connection rod structure is connected with a pneumatic nut screwing machine while the other end is fixed onto a middle sleeve; a hinge connected with the pneumatic screwing machine is enabled to move along the horizontal direction by screwing nuts; and the rhomboid structures enable the screwing machine to be kept vertical in the moving process. The loosening effect is achieved by the match between a spring and the nuts, the work efficiency is improved due to the simple structure of the mechanism, the universality of the screwing tools is improved, the cost of a company is reduced, and the economic benefits are improved.
Description
Technical field
The utility model relates to a kind of novel changable diameter tightening mechanism, especially can realize the adjusting of pneumatic tightening machine on diametric(al) of circumference layout.
Background technology
In automobile and other industries, for the picture automobile axle housing, in this industry that need to tighten the uniform bolt of circumferencial direction of automobile tire, often adopt a cover product to cooperate a cover fastener for bolt, this device because it lacks versatility, can not be used in the operation of other similar products after fulfiling assignment with batch products again, and be in long-term idle state, this has not only reduced the value of machine, and has reduced the economic benefit of company, so that the wasting of resources.
Therefore, prior art awaits further improving and development.
Summary of the invention
The utility model for solve existing for tightening tool versatility in the work of circumference uniform distribution bolt tightening poor problem.For it provides a kind of easy to use, the novel changable diameter tightening mechanism that can realize regulating circumferential orient diameter size.
The utility model for achieving the above object, the technical solution of employing is:
Be comprised of some groups of triangles and parallelogram composite rod structure, triangular form linkage hypotenuse one end in every group of composite rod mechanism connects the pneumatic nut tightening machine, and the other end is fixed on the intermediate sleeve.By rotating nut up and down so that sleeve can move up and down along central screw, feature according to triangular structure, be with an end along continuous straight runs move left and right of the pneumatic tightening machine that is dynamically connected, parallelogram sturcutre can make pneumatic tightening machine remain vertical in moving process.Intermediate sleeve lower end spring increases structural flexibility in adjustment process, and can play the effect of loosening after adjusting is finished.
A triangular structure is arranged by the length of conversion sleeve 3 place right-angle sides, change another right-angle side length, namely tightening machine is to the distance in the center of circle.
A parallelogram sturcutre is arranged, by keeping sleeve 3 place rectilinear directions constant, only change it and two face edge direction, edge direction is still remained unchanged, make tightening machine 6 directions all the time perpendicular to support 8 thereby allow.
Mechanism structure is simple, has improved the versatility of tightening tool, and can be for company's Cost reduction, increase economic efficiency.
Invention book accompanying drawing
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Sequence number among the figure: screw rod 1, nut 2, sleeve 3, connecting rod 4, spring 5, pneumatic tightening machine 6, guide rail 7, support 8, lever 9.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment the present invention is done to describe further.
Referring to Fig. 1, in use, rotating nut 2, so that sleeve 3 can move up and down along screw rod 1 at vertical direction, thereby the length that makes triangular structure middle sleeve 3 place right-angle sides produces relatively and changes, tightening machine 6 downside hinges move along horizontal guide rail 7 in the horizontal direction, thereby tightening machine 6 auto levelizer centers are played adjusting apart from size, two parallel connecting rods and sleeve 3 and pneumatic tightening machine 6 form parallel-crank mechanisms in every group of composite structure, can guarantee in adjustment process, pneumatic tightening machine 6 is parallel with sleeve place rectilinear direction all the time, namely with perpendicular to support 8, when pneumatic tightening machine 6 present positions stop adjusting to nut 2 when diametric(al) reaches the precalculated position, this moment, the spring 5 of sleeve 3 lower ends cooperated the locking effect of playing with nut 2, in addition, spring 5 can also increase the flexibility of system.
