Summary of the invention

The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, propose lower riveter in a kind of self-binder Swing lifting mechanism, the technical problem to be solved is that how riveter normally swings and goes up and down under guarantee while simplify knot The failure rate of structure, reducing mechanism.

Object of the invention can be realized by the following technical scheme:

The swing lifting mechanism of lower riveter in a kind of self-binder including gyration block, guide post and can rotate Rotating shaft, the gyration block are connected on rotating shaft, and the guide post is set on the swinging track of gyration block, and feature exists In the gyration block is threadedly coupled with rotating shaft, and gyration block lower end is fixed with rotating prevention sleeve, and the lower end of rotating shaft passes through rotating prevention sleeve And expansion controlling ring-shaped insert is fixed on the lower end of rotating shaft, being equipped between the expansion controlling ring-shaped insert and rotating prevention sleeve prevents the two relative rotation Anti-rotation structure, and when gyration block is rocked to and leans with guide post rotating prevention sleeve can overcome anti-rotation structure effect and relative to Expansion controlling ring-shaped insert skids.

When in use, lower riveter is fixed on gyration block, edge bearing group guide post being positioned close on self-binder At below part, since gyration block is threaded on rotating shaft, while under the connected rotating prevention sleeve in the lower end of gyration block, rotating shaft The expansion controlling ring-shaped insert that is connected is held, is equipped with the anti-rotation structure for both preventing relatively rotating between rotating prevention sleeve and expansion controlling ring-shaped insert, therefore rotating shaft can be with Gyration block is driven to swing the swing to realize lower riveter to guide post, and gyration block and rotating shaft can be in the effects of anti-rotation structure Under remain stationary.When gyration block, which is rocked to, to lean with guide post, the swing of gyration block is prevented to be oriented to simultaneously by guide post Column apply reaction force on gyration block, enable under the reaction force of guide post rotating prevention sleeve overcome anti-rotation structure effect and It skids relative to expansion controlling ring-shaped insert, while gyration block can be moved up along the screw thread on rotating shaft, to realize the rising of upper riveter.

It needs to be respectively set for swing mechanism and elevating mechanism in compared with the prior art, lower riveting in this self-binder The swing lifting mechanism of head only by the way that gyration block is set as being threadedly coupled with rotating shaft, then match close expansion controlling ring-shaped insert and rotating prevention sleeve with And the setting of anti-rotation structure, it can realize that the swing of gyration block enables gyration block along rotating shaft in the case where there is external force simultaneously Screw thread move up, and driving source driving rotating shaft rotation need to be only set can realize the operating of entire mechanism, thus It realizes the structure and action process for significantly simplifying entire mechanism while lower riveter works normally, thus reduces swing and rise The failure rate of descending mechanism.In addition, in conventional technical means, be threadedly coupled otherwise be make two parts be fixed together or Be a wherein part by it is circumferentially fixed when so that this is realized axis by circumferentially fixed part by the rotation of another part It to movement, and is that cannot achieve the function of both rotating synchronously and can move to axial, therefore this descends riveting merely with being threadedly coupled The technical solution that the swing lifting mechanism of head uses is not conventional technical means.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, the anti-rotation structure includes several along week To the protrusion and several circumferentially arranged recesses on the inside of rotating prevention sleeve being set on the outside of expansion controlling ring-shaped insert, protrusion has elasticity And in protrusion insertion recess.

In the circumferentially arranged several flexible protrusions in the outside of expansion controlling ring-shaped insert, the circumferentially arranged number in the inside of rotating prevention sleeve Amount be than or equal to protrusion recess, by protrusion be embedded in recess in come prevent gyration block during the swing relative to return Shaft rotation, and when gyration block is rocked to and leans with guide post, and expansion controlling ring-shaped insert can be enable to pass through each protrusion The deformation of itself is successively to squeeze through recess to guarantee that gyration block can be moved up along the screw thread on rotating shaft, to make under this The swing lifting mechanism of riveter is able to simplifying structure, the failure rate of reducing mechanism.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, the recess is in continuously distributed and recessed The quantity of mouth is more than the quantity of protrusion.

It sets recess to be in continuously distributed, and the quantity of recess is more than the quantity of protrusion, can reduce revolution in this way Block is relative to the resistance being subject in rotating shaft rotation process, to guarantee that moving up for upper riveter is more stable, smooth.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, the lateral surface of the protrusion is circular arc Face is in arc transition between the shape of recess and identical and adjacent two recesses of the shape of protrusion.

The lateral surface of protrusion is arc surface, between the shape of recess and identical and adjacent two recesses of the shape of protrusion In arc transition, protrusion can be enable more easily control to squeeze through each recess in this way, to make gyration block relative to rotating shaft Rotation is lighter, smooth, guarantees the normal operation of mechanism while simplifying the internal structure of an organization structure, is not susceptible to failure.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, if on the expansion controlling ring-shaped insert circumferentially arranged with The dry through-hole through expansion controlling ring-shaped insert upper and lower end face, through-hole is identical with protrusion quantity and corresponds, and through-hole is waist-shaped hole and each leads to Hole is set on expansion controlling ring-shaped insert at corresponding protrusion.

By the setting of each through-hole, so that each protrusion on expansion controlling ring-shaped insert can preferably deform under external force It squeezes through each recess on the inside of rotating prevention sleeve, further improves gyration block and rotated when leaning with guide post relative to rotating shaft Smoothness, mechanism can operate normally again while being simplified the structure of mechanism, be not susceptible to failure.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, the upper surface and outside of the expansion controlling ring-shaped insert It between wall and is in arc transition, the lower end surface of the rotating prevention sleeve between the upper surface of expansion controlling ring-shaped insert and the upper surface of protrusion It is in arc transition between the inner wall of each recess.

Rotating prevention sleeve is fixed on gyration block, and expansion controlling ring-shaped insert is connected on rotating shaft, when gyration block and rotating shaft relative rotation Gyration block is moved up along the screw thread of rotating shaft, and such rotating prevention sleeve gradually will be disengaged mutually with expansion controlling ring-shaped insert；When gyration block and return Gyration block is moved down along the screw thread of rotating shaft when shaft rotates backward relatively, and rotating prevention sleeve moves closer to expansion controlling ring-shaped insert and matches again It is combined.It will be set as between expansion controlling ring-shaped insert upper surface and lateral wall and between expansion controlling ring-shaped insert upper surface and the upper surface of protrusion It is in arc transition, while will be also configured as between the lower end surface of rotating prevention sleeve and the inner wall of each recess in arc transition, everywhere Arc transition can play guiding role, so that rotating prevention sleeve be enable successfully to be combined together again with expansion controlling ring-shaped insert.

In above-mentioned self-binder in the swing lifting mechanism of lower riveter, the rotating prevention sleeve adopt it is made of plastic simultaneously It is annular in shape, there is the mounting portion of cyclic annular protrusion, rotating prevention sleeve and gyration block are by passing through mounting portion simultaneously on the outside of the upper end of rotating prevention sleeve The fastener penetrated in gyration block lower end surface is mutually fixed, and several reinforcements are provided between mounting portion lower end surface and rotating prevention sleeve lateral surface Muscle piece.

Outside active force can be generated to the inner wall of rotating prevention sleeve when protrusion squeezes through each recess, although the spy of plastics itself Property can allow rotating prevention sleeve to reset, but may still occur the case where rotating prevention sleeve extends out deformation after long-time use, this meeting is so that convex The cooperation of portion and recess becomes not close out, to cause gyration block under no external force relative to the rotation of rotating shaft.Cause This, several reinforcing rib pieces are arranged between mounting portion lower end surface and rotating prevention sleeve lateral surface, increase anti-rotation using each reinforcing rib piece The structural strength of set further reduced the failure rate of mechanism to guarantee the fitment stability of rotating prevention sleeve and expansion controlling ring-shaped insert.

It is described as another technical solution in above-mentioned self-binder in the swing lifting mechanism of lower riveter The inner sidewall of rotating prevention sleeve is circumferentially arranged with several connecting holes, and the lateral wall of the expansion controlling ring-shaped insert is circumferentially arranged with several grooves, even Connect hole it is identical as number of recesses and correspond, the anti-rotation structure includes the spring and steel ball being all set in connecting hole, Steel ball is partially submerged into groove under the elastic force effect of spring, and the bottom wall of groove is cambered surface.

Spring and steel ball are equipped in connecting hole, steel ball is partially submerged into groove under the elastic force effect of spring, thus anti- Non-return switch block is rotated relative to rotating shaft during the swing, and when gyration block is rocked to and leans with guide post, and can To make rotating prevention sleeve to the direction extruding steel ball opposite with the elastic force of spring and relative to expansion controlling ring-shaped insert under the reaction force of guide post It skids, to guarantee that gyration block can be moved up along the screw thread on rotating shaft, to make the swing lifting mechanism of this lower riveter It is able to simplifying structure, the failure rate of reducing mechanism.In above-mentioned self-binder in the swing lifting mechanism of lower riveter, institute The rotating shaft stated is screw rod, and the gyration block includes the block of rectangular shape, and block has above and below block at inner end The location hole of side, positioning hole are fixed with swivel nut, and gyration block is threadedly coupled by swivel nut with rotating shaft.
