Description
Technical field
The invention belongs to frock clamp field, particularly relate to a kind of centralizer.
Background technology
In the outer cone or tooth Profile Machining of gear, need first workpiece to be felt relieved, the most typically use polished rod
Workpiece is felt relieved.Owing to being matched in clearance between polished rod and the centre bore of workpiece, thus can not have
Workpiece is felt relieved by effect ground, and centering precision is poor, thus causes the outer cone after processing eccentric, and then can not expire
Foot requirement on machining accuracy.
Summary of the invention
The technical problem to be solved is the centralizer providing a kind of centering precision high.
Technical scheme is as follows: a kind of centralizer, it is characterised in that: include clamp body (1) and
Relief tube (2), wherein the material of clamp body (1) is spring steel, and the centre bore (1a) of this clamp body is two
Segmentation 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 oil filler point section
Diameter is more than the diameter of screwed hole section；The oil inlet end of described relief tube (2) is connected on the center of clamp body (1)
In hole (1a) screwed hole section, this relief tube is provided with a relief valve (3)；
Described clamp body (1) is four-part form multidiameter structure, be followed successively by from left to right the first cylindrical section (1b),
Second cylindrical section (1c), the 3rd cylindrical section (1d) and the 4th cylindrical section (1e), wherein first, second and third
The diameter of cylindrical section increases successively, the diameter of described 4th cylindrical section (1e) between second and third cylindrical section (1c,
Between 1d)；The 1/2-2/3 of a length of clamp body (1) length of described first cylindrical section (1b), and the
The screwed hole section of position correspondence clamp body centre bore (1a) of one cylindrical section (1b) and oil filler point section left part；
It has been evenly distributed at least 3 heavy stand holes (1f) on 3rd cylindrical section (1d) of described clamp body (1),
This heavy stand hole is axially arranged and left large and right small along clamp body (1).
In technique scheme, the clamp body (1) of the present invention is by being located in the spiral shell in heavy stand hole (1f)
Follow closely the main shaft with lathe to fix, 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), then by hydraulic pump to clamp body (1)
Centre bore (1a) oil filler point section injection pressure oil, owing to the material of clamp body (1) is spring steel, this
Sample just can make the first cylindrical section (1b) distending of clamp body (1), thus in the centre bore of swelling workpiece is whole
Wall, and then realize centering, and centering precision is high；After completing processing, open relief valve (3), thus can
By relief tube (2) release, now first cylindrical section (1b) of clamp body (1) reduces, consequently facilitating
Unload workpiece.It addition, we can regulate centre bore (1a) by the open degree controlling relief valve (3)
Oil filler point section oil pressure, thus adjust the size of tension force.
Using above technical scheme, workpiece can very effectively be felt relieved by the present invention, and centering precision is high, adjusts
Press convenient and swift, and the simple in construction of the present invention, it is easy to implement, easy to use, there is good practicality.
In order to improve sealing, the 4th cylindrical section (1e) periphery of described clamp body (1) is provided with one
Cannelure (1g), and an annular seal groove (1h) it is provided with in the right side of the 4th cylindrical section.
Beneficial effect: workpiece can very effectively be felt relieved by the present invention, centering precision is high, and pressure regulation is convenient fast
Victory, and the simple in construction of the present invention, it is easy to implement, easy to use, there is good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of centralizer, mainly it is made up of clamp body 1, relief tube 2 and relief valve 3.
Wherein, the material of clamp body 1 is spring steel, and the centre bore 1a of this clamp body 1 is two-part combination bore, and
It is 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 more than screwed hole
The diameter of section.The oil inlet end of described relief tube 2 is connected in the centre bore 1a screwed hole section of clamp body 1, and this unloads
One relief valve 3 is installed in pressure pipe, and the oil outlet end of relief tube 2 can have hydraulic pump to be connected.
Described clamp body 1 is four-part form multidiameter structure, be followed successively by from left to right the first cylindrical section 1b, second
