Description
Technical field
The utility model belongs to frock clamp field, particularly relates to a kind of centralizer.
Background technology
In the outer cone or tooth Profile Machining 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 centralizer providing a kind of centering precision high.
The technical solution of the utility model is as follows: a kind of centralizer, it is characterized in that: comprise clamp body (1) and relief tube (2), 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; The oil inlet end of described relief tube (2) is connected in centre bore (1a) the screwed hole section of clamp body (1), this relief tube is provided with a relief valve (3);
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.
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 relief valve (3), so just by relief tube (2) release, now first cylindrical section (1b) of clamp body (1) reduces, thus is convenient to unload workpiece.In addition, we can regulate the oil filler point section oil pressure of centre bore (1a) by the open degree controlling relief valve (3), thus the size of adjustment tension force.
Adopt above technical scheme, the utility model can be felt relieved to workpiece very effectively, and centering precision is high, and pressure regulation is convenient and swift, and structure of the present utility model is simple, easy to implement, easy to use, has good practicality.
In order to improve sealing, the 4th cylindrical section (1e) periphery of described clamp body (1) is provided with a cannelure (1g), and is provided with an annular seal groove (1h) 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 pressure regulation is convenient and swift, and structure of the present utility model is simple, easy to implement, easy to use, there is good practicality.
