Description
Technical field
The utility model belongs to frock clamp field, particularly relates to a kind of outer taper thread grinding centralizer.
Background technology
In the outer cone grinding of gear, need first to feel relieved to workpiece, the general polished rod that adopts is felt relieved to workpiece at present.Owing to being matched in clearance between polished rod and the centre bore of workpiece, so just can not effectively feel relieved to workpiece, centering precision is poor, thus causes the outer cone after processing eccentric, and then can not meet requirement on machining accuracy.
Utility model content
Technical problem to be solved in the utility model is the outer taper thread grinding centralizer providing a kind of centering precision high.
The technical solution of the utility model is as follows: a kind of outer taper thread grinding centralizer, it is characterized in that: comprise clamp body (1), plug (2) and oil return pipe (3), wherein the material of clamp body (1) is spring steel, the centre bore (1a) of this clamp body is two-part combination bore, and be formed by connecting by the screwed hole section on the left side and the oil filler point section on the right, and the diameter of oil filler point section is greater than the diameter of screwed hole section; Described plug (2) is contained in centre bore (1a) the screwed hole section place of clamp body (1), and the right part of this plug reaches in the oil filler point section of centre bore (1a); Described clamp body (1) is four-part form multidiameter structure, be followed successively by the first cylindrical section (1b), the second cylindrical section (1c), three cylindrical section (1d) and the 4th cylindrical section (1e) from left to right, wherein the diameter of first, second and third cylindrical section increases successively, and the diameter of described 4th cylindrical section (1e) is between second and third cylindrical section (1c, 1d); The length of described first cylindrical section (1b) is the 1/2-2/3 of clamp body (1) length, and the screwed hole section of the concrete centre bore of position corresponding clip (1a) of the first cylindrical section (1b) and oil filler point section left part;
The three cylindrical section (1d) of described clamp body (1) is circumferentially evenly equipped with at least 3 heavy stand holes (1f), this heavy stand hole is arranged along the axis of clamp body (1), and left large and right small; Described three cylindrical section (1c) also on have a radial hole (1g), the outer aperture place of this radial hole has been connected by screw a described oil return pipe (3), and the inner of radial hole (1g) is communicated with in the middle part of the oil filler point section of clamp body centre bore (1a).
In technique scheme, clamp body of the present utility model (1) is fixed by the main shaft being located in screw in heavy stand hole (1f) and lathe, and the 4th cylindrical section (1e) of clamp body (1) realizes sealing.During clamping, first workpiece is sleeved on first cylindrical section (1b) of clamp body (1), again by the oil filler point section injection pressure oil of hydraulic pump to the centre bore (1a) of clamp body (1), because the material of clamp body (1) is spring steel, so just can make the first cylindrical section (1b) distending of clamp body (1), thus the whole inwall of the centre bore of swelling workpiece, and then realize centering, and centering precision is high; After completing processing, open the valve be connected with oil return pipe (3), so just energy oil return, release, now first cylindrical section (1b) of clamp body (1) reduces, thus is convenient to unload workpiece.In addition, we can by adjustment plug (2) be screwed into the oil filler point section oil pressure that the degree of depth regulates centre bore (1a), thus adjustment tension force size.
Adopt above technical scheme, the utility model can be felt relieved to workpiece very effectively, and centering precision is high, and structure of the present utility model is simple, easy to implement, easy to use, has good practicality.
In order to consider sealing, the 4th cylindrical section (1e) periphery of described clamp body (1) is provided with a cannelure (1h), and is provided with an annular seal groove (1m) in the right side of the 4th cylindrical section.
Beneficial effect: the utility model can be felt relieved to workpiece very effectively, and centering precision is high, and structure of the present utility model is simple, easy to implement, easy to use, there is good practicality.
