Abstract
The utility model discloses a piston rod special use is top, including the cylindric base, cylindric base one end is equipped with the roof pressure face, is fixed with conical thimble on the roof pressure face, and the both sides that lie in the thimble on the roof pressure face are fixed with left and right limiting plate respectively, be equipped with the wearing layer on the medial surface of limiting plate respectively. Use the utility model discloses afterwards, it is tight not need boring machine drilling and four -jaw chuck to press from both sides, and the process is few, and the work efficiency is high. Use three -jaw chuck can press from both sides tight realization finish turning. The work efficiency improves 13.
Description
technical field:
The utility model relates generally to a kind of piston rod center special.
background technology:
In prior art, the processing of piston rod is taked first to use boring machine drill centers, is installed with chuck and parallels, and the top mode that holds out against of afterbody is processed.So, there is the time that is installed long, the shortcoming that work efficiency is slow.
utility model content:
The utility model object is exactly the defect in order to make up prior art, provides a kind of piston rod center special, uses its assembling piston rod convenient and swift.
The utility model is achieved through the following technical solutions:
A kind of piston rod center special, it is characterized in that: include cylindrical base, cylindrical base one end is provided with top pressure surface, and top pressure surface is fixed with conical thimble, and both sides top pressure surface being positioned at thimble are fixed with left and right limiting plate respectively; The medial surface of described limiting plate is respectively equipped with wearing layer.
A kind of piston rod center special, is characterized in that: described wearing layer is polycyanate ester coating.
During operation, piston rod one end scroll chuck clamps, and other end the utility model pushes against, and scroll chuck rotating piston bar rotates, thus reaches turning object.
The utility model has the advantages that:
After using the utility model, do not need boring machine to hole and chuck clamping, operation is few, and work efficiency is high.Use scroll chuck to clamp and realize finish turning.Work efficiency improves 1/3.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
See accompanying drawing.
A kind of piston rod center special, include cylindrical base 1, cylindrical base 1 one end is provided with top pressure surface, and top pressure surface is fixed with conical thimble 2, and both sides top pressure surface being positioned at thimble 2 are fixed with left and right limiting plate 3,4 respectively; The medial surface of described limiting plate 3,4 is respectively equipped with wearing layer 5.
Wearing layer 5 is polycyanate ester coating.
