Background technology
In the cylinder barrel manufacturing process of hydraulic cylinder, since the seamless steel pipe of outsourcing only has endoporus to finish, outer circle,
Both ends of the surface need to carry out secondary operation all without processing or finishing.In order to meet geometric tolerances requirement, first vehicle one is generally taken
The section outer circle concentric with endoporus（The surface processed is technological datum）, then this section of outer circle is supported using centre frame add again
Work.This section of outer circle belongs to technological requirement, and non-product design requirement, but if not processing, later each process can not just carry out.The section
Outer circle not only influences product appearance quality, and reduces cylinder barrel intensity；In addition, even if machined this section of outer circle, there is also dresses
The problem of folder, centering difficulty, if using the swollen one end endoporus of three-jaw self-centering chuck, centering other end endoporus, take a lot of work, is time-consuming,
Quality is unsecured；Using four-jaw chuck card outer circle, centering other end endoporus, also there is same problem, due to needing while protecting
Card both ends endoporus center is overlapped with lathe center, and centering is more difficult.Above two clamping, centering mode all must chuck jaw with
Workpiece be line contact, otherwise, the other end will be unable to centering, which can cause to damage to endoporus, and its cutting resistance and
Resist the ability of other external force also very low.In order to improve the ability of cutting resistance, other external force, end face is often first processed, is then used
Tailstock centre withstands this section of outer surface of reprocessing, but there are still drag low problems when processing end face.Process this section of outer surface most
Reliable method is processed using cylindrical mandrel, clamps mandrel processing method especially with centering, but still have in its practice as follows
Problem is difficult to solve：1）Although seamless steel pipe inner bore diameter is identical, length is different, must be equipped with different centering and clamp the heart
Axis；2）Because centering is clamped, mandrel is elongated to pass through seamless steel pipe inner bore, can not ensure not damage bore area；3）Because of it
The centering clamping mandrel of reasons in structure, major diameter is excessively heavy.Currently, there is a kind of simple centering to clamp mandrel, problem is
Nearly all there is damage to bore area after clamping, can not also be taken out after clamping sometimes, in addition, although diameter of bore is identical, length
Different seamless steel pipe is it is necessary that with the mandrel of different length, high processing costs.
