Description
Technical field
The utility model is related to a kind of feeding device, particularly a kind of jacking device for main shaft.
Background technology
At present, turbine-generator units the manufacturing during, to core part such as main shaft of every unit etc., be intended into
Row carries out the experiment such as related mechanical properties, analysis of chemical composition with materials on batch of material and itself parent.Existing materials hand
Section mainly uses drilling machine, and multiple aperture drilling materials, not only trivial operations, and multiple are carried out to the end face of the parts such as main shaft
Aperture must also carry out secondary operation after drilling through, and waste time and cost；Meanwhile, by boring aperture materials it also occur that materials
The problem of measuring inadequate.
Utility model content
The purpose of this utility model is just to provide a kind of jacking for main shaft that can be easily and fast drawn materials and filled
Put.
The purpose of this utility model realized by such technical scheme, a kind of jacking device for main shaft, institute
Stating jacking device has the knife bar of Morse taper including one end, hollow cutter head is provided with the other end of the knife bar, in institute
State and the blind hole that one end is communicated with cutter head is provided with knife bar, be arranged with overcoat successively at the middle part of the knife bar and for fixed outer
The round nut of set, vertical knife bar is provided with the joint for penetrating overcoat on the outer set, is provided with the joint and blind hole
The feed pathway of connection.
In order to prevent overcoat from moving, be provided with boss in one end of the knife bar, it is described it is outer be set on boss side and
It is spacing by boss, on the knife bar and positioned at being provided with packing ring between boss and overcoat.
In order to prevent coolant from overflowing, a pair of annular grooves are provided with the inwall of the overcoat, the annular groove is located at respectively
Joint both sides, sealing ring is provided with the annular groove.
In order that joint and overcoat are fixed, on the top of the joint and vertical joint is provided with guide block.
By adopting the above-described technical solution, the utility model have it is simple in construction, easy to operate, with low cost excellent
Point, quickly and easily can carry out feeding operation, it is ensured that one time feeding is enough, it is therefore prevented that secondary to add using it to parts such as main shafts
Work, meanwhile, also meet the uniformity of the properties of experiment material and parent itself, it is ensured that the accuracy of experimental configuration.
