Piston rod in use related to process analysis
Dec 26, 2017

Piston rod in the use of time, will bear the effect of alternating load, so that will not only make the piston rod has a certain toughness, then say it, to a large extent, it should be noted that it should be To have better wear resistance.

 

Then, in fact, we should pay attention to the structure of the piston rod itself is relatively simple, but its relatively large aspect ratio, belonging to the slender shaft parts, the rigidity is also very poor, in order to ensure its machining accuracy, in the Turn the time to pay attention to the rough car, fine car separately, and its rough, fine car is to pay attention to the use of the knife holder, in terms of this point, that is, to reduce the deformation of the workpiece when processing, at When processing both ends of the thread to pay attention to the use of the center frame.

 

Furthermore, the piston rod in the choice of positioning time, in order to ensure that parts of the coaxial tolerance and the mutual accuracy of the various parts, for all the processing procedures in terms of words, it should be noted that it is necessary to use two center hole positioning , To that extent, to a large extent it will be more in line with the principle of unity of the benchmarks themselves.

 

Finally, when grinding the outer surface, in the case of workpieces, it is easier to produce a knife or elastic deformation, which is to a very large extent Affected the accuracy of the piston rod. In view of this, in the processing of piston rod, it should be to study the center hole, this time, that is, to ensure that the center hole cleaning, and should pay attention to ensure good lubrication.http://www.xhychromerod.com/
