Abstract
The utility model discloses an anti-dropping riveting fixture tool for a pulling rod. The anti-dropping riveting fixture tool is a tower-shaped cylindrical rivet joint. The bottom of the tower-shaped cylindrical rivet joint is provided with an inner concave circle. The diameter of the inner concave circle is less than the external diameter of the tower-shaped cylindrical rivet joint. An inner bevel is arranged on the periphery of the inner concave circle. The intersection position of the inner concave circle and the inner bevel is provided with an inner arc angle. The edges at two ends of the tower-shaped cylindrical rivet joint are provided with outer chamfering. By the above method, an original arc design is changed into a tower-shaped design and the inner concave circle is packaged and pressed inwards so that the rivet joint is prevented from being cracked during a riveting process.
Description
Technical field
The utility model relates to riveted joint field, particularly relates to a kind of slip-off preventing pull bar riveting tool instrument.
Background technology
Riveting machine (being also referred to as rivet driver, riveter, lock seaming machine, rolling riveter etc.) is a kind of novel riveting equipment developing according to cold rolling principle, just refers to and can article be riveted to mechanized equipment with rivet.This compact equipment, stable performance, easy and safe to operate.Riveting machine mainly completes assembling by rotation and pressure, is mainly used in the occasion that needs rivet (hollow rivet, tubular rivet, solid rivet etc.) riveted, common are pneumatic, oil pressure and electronic, single head and double end equal-specification model.
After the riveted joint of existing riveting tool riveted joint, size is little, easily causes cracking and comes off, and existing frock riveted joint riveted joint size is unstable, it is large to beat, riveted joint rear perimeter edge cracking, external diameter is little and easily come off.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of slip-off preventing pull bar riveting tool instrument, original circular arc design can be changed into turriform design, the inside bag pressure of indent circle, thus accomplish to avoid the generation at riveted joint process cracking.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of slip-off preventing pull bar riveting tool instrument is provided, described slip-off preventing pull bar riveting tool instrument is a turriform cylinder riveted joint, the bottom of described turriform cylinder riveted joint is provided with indent circle, described indent diameter of a circle is less than the external diameter of turriform cylinder riveted joint, the periphery of described indent circle is provided with inner bevel, described indent circle is provided with interior arc chord angle with the intersection of inner bevel, and described turriform cylinder riveted joint edges at two ends place is provided with outer chamfering.
Preferably, described turriform cylinder riveted joint is also provided with annular groove, and described annular groove, in order to collar to be installed, connects riveted joint tightr.
Preferably, the angle between described inner bevel and turriform cylinder riveted joint central axis is 48 °, and the performance in the time of 48 ° is the most stable, not easy to crack, has increased the stability of riveted joint.
The beneficial effects of the utility model are: the utility model adopts the design of turriform cylinder riveted joint, and the inside bag pressure of indent circle, avoids riveted joint to ftracture in riveted joint process, and manufacture, simple installation, reduced bad cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of slip-off preventing pull bar of the utility model riveting tool instrument one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, annular groove, 2, outer chamfering, 3, indent circle, 4, interior arc chord angle, 5, inner bevel.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of slip-off preventing pull bar riveting tool instrument, described slip-off preventing pull bar riveting tool instrument is a turriform cylinder riveted joint, the bottom of described turriform cylinder riveted joint is provided with indent circle 3, the diameter of described indent circle 3 is less than the external diameter of turriform cylinder riveted joint, the periphery of described indent circle 3 is provided with inner bevel 5, described indent circle 3 is provided with interior arc chord angle 4 with the intersection of inner bevel 5, described turriform cylinder riveted joint edges at two ends place is provided with outer chamfering 2, compare with existing circular arc riveted joint, bottom adopts turriform design, increased indent circle 3, indent circle 3 inside bag pressures, thereby avoid riveted joint in riveted joint process to ftracture.
Further, on described cylinder, be also provided with annular groove 1, the outer collar that arranges of annular groove 1, make between riveted joint and workpiece be connected tightr.
Further, the angle between described inner bevel 5 and turriform cylinder riveted joint central axis is 48 °, and angle tolerance is 1 °, and when the angle between inner bevel 5 and axis is 48 °, riveted joint performance is more stable, not easy to crack.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
