Utility model content
The purpose of this utility model is to solve the problem, and provides a kind of novel belt stepless speed changing adjustment device.
Belt stepless speed changing adjustment device described in the utility model comprises: connecting axle, first pulley, second pulley, fixed axis, torsion spring and torsion spring collar, the first described pulley is fixedly installed on one end of this connecting axle by screw, the second described pulley is arranged on the other end of this connecting axle, and the first pulley and the second pulley are positioned at the same side of this connecting axle; Described fixed axis is perpendicular to this connecting axle, and the axle center of this fixed axis is through the center of the second pulley; This fixed axis is arranged with torsion spring, and described torsion spring collar is set on this fixed axis, for limiting moving axially of torsion spring; This torsion spring is provided with the first cantilever, this first cantilever is connected with the second cantilever, and this second cantilever is stuck on described connecting axle.
The first described cantilever and the second cantilever vertical.
Described fixed axis and the second pulley lay respectively at the not homonymy of this connecting axle.
Described torsion spring drives connecting axle to twist back and forth, carrys out check strap with this.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
Because the elastic force of PU round belt is limited during the distance of double-headed riveting nailing machine in the past between adjustment two rivet, adjustable range scope is larger.Often occur that PU round belt joint disconnects, machine just cannot normally work.Because this PU round belt cannot be bought in general shop, making applying unit cause cannot the unnecessary loss of shipment.Belt stepless speed changing adjustment apparatus structure described in the utility model is reasonable, original basis adds the region of a buffering, belt is after this buffer area, connecting axle is driven to twist back and forth by torsion spring, check strap is carried out with this, make it that fracture be less likely to occur, so the effect of buffering can extend the life-span of belt, in general can use and can not rupture for more than 5 years.
Accompanying drawing explanation
Fig. 1 is the assembly drawing of belt stepless speed changing adjustment device described in the utility model.
Fig. 2 is the structural principle schematic diagram of belt stepless speed changing adjustment device described in the utility model.
Wherein, 1-connecting axle, 2-first pulley, 3-second pulley, 4-screw, 5-fixed axis, the collar of 6-torsion spring, 7-torsion spring, 8-first cantilever, 9-second cantilever, 21-main pulley, 22-loading hopper assembly.
Detailed description of the invention
Be clearly and completely described the technical scheme in the utility model below in conjunction with accompanying drawing, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
Because the elastic force of PU round belt is limited during the distance of double-headed riveting nailing machine in the past between adjustment two rivet, adjustable range scope is larger.Often occur that PU round belt joint disconnects, machine just cannot normally work.Because this PU round belt cannot be bought in general shop, making applying unit cause cannot the unnecessary loss of shipment.
As shown in Figure 1-2, belt stepless speed changing adjustment device described in the utility model comprises: connecting axle 1, first pulley 2, second pulley 3, fixed axis 5, torsion spring 7 and torsion spring collar 6, the first described pulley 2 is fixedly installed on one end of this connecting axle 1 by screw 4, the second described pulley 3 is arranged on the other end of this connecting axle 1, and the first pulley 2 and the second pulley 3 are positioned at the same side of this connecting axle 1; Described fixed axis 5 is perpendicular to this connecting axle 1, and the axle center of this fixed axis 5 is through the center of the second pulley 3; This fixed axis 5 is arranged with torsion spring 7, and described torsion spring collar 6 is set on this fixed axis 5, for limiting moving axially of torsion spring 7; This torsion spring 7 is provided with the first cantilever 8, this first cantilever 8 is connected with the second cantilever 9, and this second cantilever 9 is stuck on described connecting axle 1.
The first described cantilever 8 is vertical with the second cantilever 9.
Described fixed axis 5 and the second pulley 3 lay respectively at the not homonymy of this connecting axle 1.
As shown in Figure 2, loading hopper assembly 22 has and respectively has a small belt pulley, the main pulley in main machine body realizes the small belt pulley of transmission two loading hoppers by PU round belt, thus makes loading hopper blanking.In production process, a work period can play two rivets simultaneously.
Due to the needs of different product, also different to centre distance dimensional requirement between two rivets, therefore by fuselage roll adjustment.Regulate the distance of slave body and main machine body.In the process because the amplitude of accommodation is comparatively large, and PU round belt finite elastic.Frequent generation PU round belt joint disconnects.Or due to belt too pine cannot drive belt pulley.Can realize stepless adjustable after installing this device additional, PU round belt is within the scope of the suitable elastic force of degree of tightness all the time.Not easily broken, durable in use.
When main pulley 21 drives loading hopper assembly 22 to rotate time, described torsion spring drives connecting axle to twist back and forth, carrys out check strap with this, makes it that fracture be less likely to occur.This is just equivalent to the region adding a buffering on original basis, belt is after this buffer area, connecting axle is driven to twist back and forth by torsion spring, check strap is carried out with this, make it that fracture be less likely to occur, and belt is being not easy to buy on the market, does not also have the belt of other materials can replace present belt, so the effect of buffering can extend the life-span of belt, 2-3 in general can be used to rupture.
In sum, be the utility model embodiment content, and obvious embodiment of the present utility model is not limited in this, it according to different application environment, can utilize functional realiey corresponding demand of the present utility model.
