Abstract
The utility model discloses a high-stability connecting rod. The high-stability connecting rod comprises a rod body, a locating shaft, a locating block and a piston. One end of the locating shaft is connected with the tail portion of the rod body. The other end of the locating shaft is connected with the locating block. The piston is located on the outer circumference of the locating shaft. The locating shaft and the locating block are fixedly connected through a nut and a flat gasket. A buffer spacer is arranged on the connection portion of the rod body and the locating shaft. Due to the fact that a stop block is arranged between the rod body and the locating shaft, the fixed connection between the rod body and the locating shaft can be guaranteed, and the purpose that the impact force of the rod body on the locating shaft is reduced is guaranteed. Therefore, the service life of the connecting rod is prolonged.
Description
Technical field
The utility model relates to a kind of connecting rod for association areas such as automobile, bicycles.
Background technique
Connecting rod, as in the machine activity, using the most general equipment, just directly affects the performance of apparatus in its working stability and working life.In common single-rod piston, piston is positioned at an end of connecting rod, piston is sleeved on the positioning shaft of connecting rod by the center hole with the connecting rod coupling, the diameter of positioning shaft is less than the bar footpath of connecting rod, with the afterbody at positioning shaft, form the carrying location shaft shoulder, then by the nut on positioning block, piston is locked on connecting rod.Tool withdrawal groove while leaving machining screw between positioning block and positioning shaft, when piston bore load shown in the diagram arrow, tool withdrawal groove was the stress concentration portion position, when load was excessive, connecting rod was at first by tool withdrawal groove 7 places fracture.After fracture, piston is trapped in cylinder body, and connecting rod skids off cylinder body along the tie rod holes on cylinder body, in cylinder body, a large amount of hydraulic oil leaks rapidly at short notice, not only interrupt the normal operation of oil hydraulic cylinder, go back therefore severe contamination operating environment, and brought heavy cleaning work amount to repairing.When this kind connecting rod is used for the locked hydraulic cylinder of metallurgical acid cleaning galvanizing equipment, due to work under bad environment, load impacting power is large, therefore connecting rod cracking, slippage accident occurrence frequency are very high, just there will be the disconnected bar of connecting rod to skid off accident in tens days, had a strong impact on the normal operation of pickling galvanizing equipment and caused very large economic loss., must improve the structure of connecting rod joint, to overcome the familiar lacunas such as its fracture in use existed, slippage for this reason.
The model utility content
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, the connecting rod of the high and long service life of a kind of stability provided.
Technological scheme: in order to realize above purpose, a kind of high stability connecting rod described in the utility model, comprise the body of rod, positioning shaft, positioning block, piston, protection cylinder body, described positioning shaft one end is connected with body of rod afterbody, the other end is connected with positioning block, described piston is located at the excircle of positioning shaft, and described positioning shaft is fixedly connected with by nut and plain cushion with positioning block; Described protection cylinder body is located at the outer rim of piston, and the outlet of described body of rod self-protection cylinder body is stretched out; The joint of the described body of rod and positioning shaft is provided with buffering spacer.
Positioning block and the positioning shaft of described connection piston are isometrical.
The diameter of described buffering spacer is greater than the diameter of protection cylinder body outlet.
Beneficial effect: compared with prior art, the utility model is by being fixedly connected with of cushion pad lamellar body and positioning shaft is set between the body of rod and positioning shaft, by guaranteeing to reduce the impact force of the body of rod to positioning shaft, thus the working life of improving connecting rod.
Described positioning block and positioning shaft are isometrical, can either guarantee that piston position is relatively stable, can simplify again the packaging technology of connecting rod, enhance productivity.
Described buffering spacer diameter is greater than the diameter of protection cylinder body outlet, when the body of rod moves up and down, can prevent that the body of rod from skidding off the protection cylinder body, affects machine work, effectively improves working stability and the working life of connecting rod.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
A kind of high stability connecting rod as shown in Fig. 1 figure, its concrete structure is: comprise the body of rod 8, positioning shaft 1, positioning block 2, piston 4, described positioning shaft 1 one ends are connected with the body of rod 8 afterbodys, the other end is connected with positioning block 2, described piston 4 is located at the excircle of positioning shaft 1, and described positioning shaft 1 is fixedly connected with by nut 5 and plain cushion 6 with positioning block 2; Described protection cylinder body 7 is located at the outer rim of piston 4, and the outlet of the described body of rod 8 self-protection cylinder bodies 7 is stretched out the described body of rod 8 and is provided with buffering spacer 3 with the joint of positioning shaft 1, and the described body of rod 8 is isometrical with positioning shaft 1; The diameter of described buffering spacer 3 is greater than the diameter of protection cylinder body 7 outlets.
By guaranteeing being fixedly connected with of the body of rod 8 and positioning shaft 1 buffering spacer 3 is set between the body of rod 8 and positioning shaft 1, by the impact force that can guarantee to reduce 8 pairs of positioning shafts 1 of the body of rod, thus the working life of improving connecting rod.
Described positioning shaft 1 and positioning block 2 are fixedly connected with and both can guarantee being fixedly connected with of positioning shaft 1 and positioning block 2 by nut 5 and plain cushion 6, again can be for convenience detach when breaking down, improved the applicability of connecting rod.
Because described positioning shaft 1 is isometrical with the body of rod 8, can effectively simplify structure of the present utility model.
When piston 4 upwards moves, buffering spacer 3 gear on the tie rod holes of cylinder body, in case stopping bar body 8 when skidding off cylinder body piston 4 stop up tie rod holes, to guarantee to improve working efficiency and the working life of connecting rod.
Above-described embodiment only is explanation technical conceive 1 of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model enforcement according to this, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence, within all should being encompassed in protection domain of the present utility model.
