Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 2, Fig. 2 is the overall structure schematic diagram of the first detailed description of the invention provided by the present invention.
In the first detailed description of the invention provided by the present invention, the disassembling tooling of Split connecting rod designs mainly for Split connecting rod, mainly comprise mount pad 1, major part mounting blocks 2 and plat shaft 3, wherein mount pad 1 is for installing all the other parts, and major part mounting blocks 2 and plat shaft 3 are just arranged on mount pad 1.
Major part mounting blocks 2 is one of core components of the present invention, as the term suggests major part mounting blocks 2 is mainly used in the stub end installing Split connecting rod, by being fixedly clamped by Split connecting rod with coordinating of major part mounting blocks 2 by the big end hole of Split connecting rod.Major part mounting blocks 2 entirety is in the form of a ring, but different from common annulus, and the outer ring of major part mounting blocks 2 is circular, but inner ring is oval.The outer ring of major part mounting blocks 2 is circle is to match with the big end hole of Split connecting rod, and in order to compactness, the diameter of circular outer ring of major part mounting blocks 2 and the equal diameters of the big end hole of Split connecting rod of shaft hole matching.In addition, the major part mounting blocks 2 in the present invention is split-type structurals, and not a domain structure, is distributed with the first slide block 201 and the second slide block 202 along its circumferential direction.And this first slide block 201 and the second slide block 202 are independent mutually, and can move horizontally, and its effect will be discussed in detail in subsequent content.
Herein preferably, the outer ring of the first slide block 201 and the second slide block 202 is semicircle, and symmetrical along the long axis direction of the inner ring of major part mounting blocks 2.In other words, major part mounting blocks 2 is divided equally by the first slide block 201 and the second slide block 202, and outer ring is semicircle naturally, and inner ring is half elliptic, and symmetry axis is then oval major axis.So, when installing Split connecting rod, connecting rod cap can be close to the outer ring of the first slide block 201 or the second slide block 202, outer due to connecting rod cap is semicircle, the outer ring of the first slide block 201 and the second slide block 202 is also the semicircle of equal diameters, so can ensure higher laminating degree and contact area, when stressed, the transmission efficiency of power also can be improved.
It is pointed out that the first slide block 201 and the second slide block 202 are not limited to divide equally and form symmetrical mutually, the outer ring central angle of all the other such as the first slide blocks 201 is 240 °, and the outer ring central angle of the second slide block 202 is the distribution form of 120 °; Or the form that the first slide block 201 and the second slide block 202 are divided equally along the short-axis direction of inner ring is feasible equally, only need manually to adjust the mode that on Split connecting rod, connecting rod cap and the first slide block 201 or the second slide block 202 are fitted.
Plat shaft 3 is another core components of the present invention, the similar typical axle class formation of its global shape, but is not cylinder, but flat cylinder.If observe its cross section can find that the cross section of plat shaft 3 is shapes of similar rectangle, the line segment length everywhere generally speaking on cross section is unequal.Plat shaft 3 is also arranged on mount pad 1, and is rotatably to be connected by horizontal rotary with mount pad 1.More particularly, plat shaft 3 is arranged in the inner ring of major part mounting blocks 2, and importantly, the maximum length on the cross section of plat shaft 3 is greater than the minor axis length (ellipse has major axis and minor axis length) of oval inner ring.Certainly, because plat shaft 3 need be arranged in inner ring, so the maximum length of its cross section is generally little than the long axis length of oval inner ring.
The disassembling tooling of Split connecting rod provided by the present invention, before work pieces process, need be installed to Split connecting rod in this frock.First, be placed into by Split connecting rod on mount pad 1, and the big end hole of Split connecting rod is coordinated with the major part mounting blocks 2 on mount pad 1, manual fine-tuning position makes big end hole coordinate with major part mounting blocks 2 closely, is so just fixed by Split connecting rod.Outer due to major part mounting blocks 2 is circular, and big end hole is also circular, and therefore big end hole and coordinating of major part mounting blocks 2 are arbitrary, and namely the length direction of Split connecting rod can be arbitrarily angled in the circumference of major part mounting blocks 2.But the splitting step of conveniently follow-up Split connecting rod herein, the installation site of adjustable Split connecting rod, makes the outer of the connecting rod cap of semicircular in shape and the first slide block 201 or the second slide block 202 fit tightly.
After installing, operator turns plat shaft 3, and plat shaft 3 is horizontally rotated.As previously mentioned, structure due to plat shaft 3 is flat, line segment length on its cross section is change, simultaneously because the inner ring of major part mounting blocks 2 is oval, and the cross section maximum length of plat shaft 3 is greater than the minor axis length of inner ring, therefore when plat shaft 3 rotates to certain angle, the edge of plat shaft 3 inherently with inner ring close contact.Then plat shaft 3 continues to rotate, and due to mutual extruding, plat shaft 3 starts to apply pressure to the first slide block 201 and the second slide block 202, and this pressure reaches maximum when plat shaft 3 rotates to the short-axis direction of inner ring.Now for major part mounting blocks 2, the power that plat shaft 3 applies is tension force.Because the first slide block 201 and the second slide block 202 can move horizontally, plat shaft 3 applied pressure is for being all thrust the two, therefore the first slide block 201 and the second slide block 202 extrude connecting rod cap and gonnecting rod body under movement tendency, when this thrust is increased to certain degree, connecting rod cap just can be forced to be separated with gonnecting rod body.Generally speaking, be the tension force applied by plat shaft 3 pairs of major part mounting blocks 2, the connecting rod cap of Split connecting rod is separated with gonnecting rod body.
In sum, the disassembling tooling of Split connecting rod provided by the present invention, by the fastening Split connecting rod of major part mounting blocks 2, then by the rotation of plat shaft 3, produce tension force when the inner ring with major part mounting blocks 2 extrudes, thus force the connecting rod cap of Split connecting rod to be separated with gonnecting rod body.Compared in prior art by the mode that artificial use instrument beats, the present invention more easily, quickly can split connecting rod, improves production efficiency.In addition; because the contact surface of connecting rod cap and the first slide block 201 or the second slide block 202 is arc surfaces; the stress surface of meaning and tension force is also arc surface; therefore compared to single-point of the prior art or small size stressed; the pressure that connecting rod cap in the present invention is subject to is less; stress is disperseed by arc surface, and available protecting workpiece is not scratched or damages.
Can also do to optimize to the structure of plat shaft 3.For this reason, the edge of plat shaft 3 is set to level and smooth curve shape by the present embodiment, so, when plat shaft 3 to contact with the inner ring of major part mounting blocks 2 and extrudes mutually, alleviates the phenomenon that stress is concentrated, avoids scratching major part mounting blocks 2.
Please refer to Fig. 3, Fig. 3 is the overall structure side view of the first detailed description of the invention provided by the present invention.
Further, coordinate compactness in order to what improve Split connecting rod and major part mounting blocks 2, the present embodiment is also provided with microcephaly's mounting blocks 4 on mount pad 1.As its name suggests, microcephaly's mounting blocks 4 is mainly used in coordinating with the little head bore of Split connecting rod, improves disassembling tooling to the tightness of Split connecting rod.In addition, because Split connecting rod lies on mount pad 1, therefore, microcephaly's mounting blocks 4 need be neat high with major part mounting blocks 2, so can ensure the horizontality of Split connecting rod, be convenient to subsequent operation.
Further, can also do to optimize to the structure of major part mounting blocks 2.For this reason, the present embodiment is provided with annular groove along its circumference on the sidewall of major part mounting blocks 2, is then wrapped in this annular groove by elastic component 5.Herein preferably, elastic component 5 is rubber band.Certainly, the form of conventional elastic component 5 is a lot, and all the other such as belt or ropes etc. also can adopt, and do not enumerate herein.So, under the elastic force effect of elastic component 5, just the first slide block 201 and the second slide block 202 are tightened up.In Split connecting rod split process, elastic component 5 is also subject to the tension force of plat shaft 3 and expands outwardly; And after Split connecting rod split process terminates, plat shaft 3 no longer applies tension force, elastic component 5 just inwardly bounces back under the effect of elastic potential energy, thus drives the first slide block 201 and the second slide block 202 to be returned to original state gradually.So by the effect of elastic component 5, make the first slide block 201 and the second slide block 202 realize the function of self-return, eliminate the process that operator manually adjusts, improve production efficiency.
Please refer to Fig. 4, Fig. 4 is the overall structure schematic diagram of the second detailed description of the invention provided by the present invention.
The second detailed description of the invention provided by the present invention, the basis of the first detailed description of the invention is improved, is specially: set up guide rail 6, joint pin 7 and rotating handles 8.The remainder of the disassembling tooling of the Split connecting rod that the present embodiment provides is identical with foregoing teachings, repeats no more herein.
In the second detailed description of the invention provided by the present invention, in order to realize the effect of the first slide block 201 and the second slide block 202 better, the present embodiment is provided with guide rail 6 on mount pad 1.First slide block 201 and the second slide block 202 are all arranged in guide rail 6, coordinate slide with guide rail 6.So, due to the existence of guide rail 6, the annexation of the first slide block 201 and the second slide block 202 and mount pad 1 by former direct Innovation of Connection for be indirectly connected.Herein preferably, guide rail 6 is line slideway, and the oval inner ring short-axis direction conllinear of the length direction of line slideway and major part mounting blocks 2.Because plat shaft 3 is when rotating to inner ring short-axis direction, its tension force applied is maximum, it is the highest that connecting rod cap and gonnecting rod body split successful probability, therefore the possibility of the first slide block 201 or the movement on this direction (short-axis direction) of the second slide block 202 is maximum, so the inner ring short-axis direction conllinear of the length direction of guide rail 6 and major part mounting blocks 2 can adapt to the actual motion situation of the first slide block 202 or the second slide block 202.
In addition, the present embodiment is provided with joint pin 7 in the bottom of plat shaft 3, and is provided with counterbore in the bottom of guide rail 6, and this counterbore can closely cooperate with joint pin 7.So, by closely cooperating of joint pin 7 and counterbore, just plat shaft 3 can be arranged on guide rail 6, and the smooth surface of guide rail 6 be conducive to raising plat shaft 3 rotate freely smoothness.
Further, consider the operation inconvenience of operator when turning plat shaft 3, the present embodiment is provided with rotating handles 8 at the top of plat shaft 3, and the length direction of this rotating handles 8 is vertical with the axial direction of plat shaft 3.Setting like this, operator just can turn plat shaft 3 by the mode of hand rotating handle 8, and due to the effect of lever principle, longer rotating handles 8 can make operator save most of strength, and is conducive to enhancing productivity.
