Description
Technical field
The utility model relates to a kind of self-locking nut machinery closing device.
Background technology
Since mechanical industry was come out, nut became one of securing member of extensive use in the industrial chain, as in industries such as building, bridge, traffic, industry, electronics, being widely used invariably; But common nut in use, and particularly the fastening effect at the vibrations lower nut can weaken, and has an accident thereby get loose voluntarily; Therefore the design that prevents that nut from getting loose has been arranged; On the plain nut that processes,, make internal thread and external screw thread play interference engagement, produce certain moment of torsion when tightening through the internal thread distortion of external force with nut; Thereby reach locking effect, this type nut is referred to as self-locking nut; In order to make self-locking nut in batch process, reach consistent locking property; The distortion size that must be internal thread is consistent; At present, generally all be to adopt scroll chuck to tighten up to self-locking nut crimping, but the amount of movement of scroll chuck double thread is uncertain; Make the closing in of self-locking nut unstable, can not reach unified locking property.
Summary of the invention
The utility model technical problem to be solved provides a kind of self-locking nut machinery closing device that guarantees product quality, makes self-locking nut crimping distortion unanimity.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of self-locking nut machinery closing device; Main body is a base and is connected the skewback on the slider of punch; Left end connects a positioning table through securing member on base top; The base upper right end is fixed with locating piece, and said positioning table left end is fixedly connected a quiet die holder, is fixed with a quiet mould on the quiet die holder; Said locating piece inside is provided with slide block, and the locating piece upper end is fixed with rocker arm bracket; Said slide block flexibly connects through base inner spring and dynamic model seat, is fixed with a dynamic model on the said dynamic model seat, and the right-hand member of dynamic model seat connects a dynamic model seat set screw; Said skewback flexibly connects through roller and rocking lever one end, and the other end of rocking lever is movably connected in the slide block groove, and said rocking lever is movably connected in the rocker arm bracket through bearing pin two.
In order to improve the service life of this mechanical closing device, the front end of said quiet mould and dynamic model welds a quiet moving die insert respectively, and said roller and rocking lever flexibly connect through bearing pin one.
After adopting said structure; Be characterized in: whole device is fixed on the punch press, and skewback is fixed on the slider of punch, through moving up and down of punch press; Skewback drives roller and rocking lever is the axle center side-to-side movement with bearing pin two, thereby drives the side-to-side movement of slide block, dynamic model seat and dynamic model; The quiet moving die insert of welding carbide alloy has increased service life on quiet mould and dynamic model, is the size of scalable closing in size through the closed height and the dynamic model seat set screw of regulating slider of punch simultaneously, guarantees its product quality and closing in size stability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the vertical view of the utility model;
Fig. 3 is the local enlarged diagram in A district among Fig. 1.
Among the figure: 1, quiet die holder 2, quiet mould 3, dynamic model 4, positioning table 5, self-locking nut 6, roller 7, rocking lever 8, bearing pin 1, bearing pin 2 10, rocker arm bracket 11, locating piece 12, slide block 13, dynamic model seat 14, spring 15, base 16, dynamic model seat set screw 17, quiet moving die insert 18, skewback.
The specific embodiment
Fig. 1, a kind of self-locking nut machinery closing device shown in Figure 2; Main body is a base 15 and is connected the skewback 18 on the slider of punch; Connect a positioning table 4 at base 15 top left ends through securing member; Base 15 upper right end are fixed with locating piece 11, and said positioning table 4 left ends are fixedly connected a quiet die holder 1, are fixed with a quiet mould 2 on the quiet die holder 1; Said locating piece 11 inside are provided with slide block 12, and locating piece 11 upper ends are fixed with rocker arm bracket 10; Said slide block 12 flexibly connects with dynamic model seat 13 through base 15 inner springs 14, is fixed with a dynamic model 3 on the said dynamic model seat 13, and the right-hand member of dynamic model seat 3 connects a dynamic model seat set screw 16; Said skewback 18 flexibly connects through roller 6 and rocking lever 7 one ends, and the other end of rocking lever 7 is movably connected in slide block 12 grooves, and said rocking lever 7 is movably connected in the rocker arm bracket 10 through bearing pin 29; Said roller 6 flexibly connects through bearing pin 1 with rocking lever 7.
The front end of quiet mould 2 shown in Figure 3 and dynamic model 3 welds a quiet moving die insert 17 respectively, under the effect of extruding external force, makes the internal thread distortion of self-locking nut 5, and the quiet moving die insert 17 that is added has prolonged the service life of the utility model.
Whole device is fixed on the punch press, and skewback 18 is fixed on the slider of punch, through moving up and down of punch press; It is the axle center side-to-side movement with rocking lever 7 with bearing pin 29 that skewback 18 drives roller 6; Thereby drive the side-to-side movement of slide block 12, slide block 12 drives the side-to-side movement of dynamic model seat 13 and dynamic model 3 simultaneously, and dynamic model 3 cooperates with quiet mould 2; Effect extruding through external force is fixed on the self-locking nut 5 on the positioning table 4; Make internal thread and external screw thread play interference engagement, produce certain moment of torsion when tightening, thereby reach locking effect; The quiet moving die insert 17 of welding carbide alloy on quiet mould 2 and dynamic model 3; Increased service life; Be the size of scalable closing in size through the closed height of adjusting slider of punch and the precession of dynamic model seat set screw 16 with screwing out simultaneously, guarantee its product quality and closing in size stability.
