Description

Background
With the advancement of material science, the wall thickness of shaft parts, especially shaft parts with hollow through holes for aircraft engines, tends to be smaller and smaller, and the outer circular surface of the shaft parts is generally provided with multiple groups of profiles. FIG. 1 is a schematic diagram of a schematic cross-sectional structural diagram of a thin-walled through-hole part for an aircraft engine, and as shown in FIG. 1, the length L1 of the thin-walled through-hole part 100 is greater than 800mm, the diameter D1 of the outer circle of a shaft body is 26mm, the length-diameter ratio exceeds 30, the wall thickness of the shaft body is not greater than 1.5mm, and the requirement of the outer circle jumping is not greater than 0.05. For the thin-wall through-hole part 100 shown in fig. 1, in the existing production process, the outer circle of the shaft body is formed by turning, and part of the step-shaped profile is prepared by grinding, because the thin-wall through-hole part 100 has a thin wall and poor rigidity, and is very easy to bend and deform when stressed in the processing process, in order to guarantee the requirement of the outer circle jumping, in the existing production processing process, a supporting device is usually required to be arranged at the position of the shaft body, so that the rigidity is guaranteed, and the processing needs to be performed in a segmented manner, thereby affecting the production efficiency. In addition, the outer circular surface of the thin-walled through-hole part 100 may also be provided with at least one set of welded boss portion 101, and for the boss portion 101, grinding is required to meet the requirement of outer circular surface run-out, so that the processing difficulty is very high.

In addition, the use of 201910997021.8 provides a mandrel that is relatively labor intensive to insert and remove due to the interference fit.
In order to overcome the defects, the team of the inventor provides a method for effectively reducing deformation influence in the machining process by filling oil in the inner cavity of the thin-wall shaft part so as to support the part and provide a special structure capable of transmitting deformation of the oil in the assembly process through design in the application of 'a thin-wall shaft part machining deformation control method' filed on the same day as the application.

The extended shank portion 22 is preferably made of a light metal such as an aluminum alloy, which reduces the labor intensity of the operation.
The working principle and the using method of the device provided by the invention are as follows:
step A, providing an ejector rod plug 2 to plug one end of the through cavity of the thin-wall through hole part' 100,
when the ejector rod plug 2 is assembled, the thin-wall through-hole part 100 can be vertically placed, then an O-shaped sealing ring (not shown in the figure) is sleeved on the first conical surface body 211, the maximum diameter of the O-shaped sealing ring is larger than the diameter of the inner cavity of the thin-wall through-hole part 100, then the extending ejector rod part 22 is inserted into the inner cavity of the thin-wall through-hole part 100, after the O-shaped sealing ring on the first conical surface body 211 is contacted with the thin-wall through-hole part 100, force can be applied to press the O-shaped sealing ring until the ejector rod plug 2 completely enters the inner cavity of the thin-wall through-hole part 100, and the distance between the first columnar part 212 and the end face of the thin-wall through-hole part 100 can be controlled to be about 5 mm.
Referring to fig. 2 and 3, in order to avoid interference of the ejector rod plug 2 on the machine tool tip as much as possible during machining, an annular rubber pad 3 may be further disposed outside the first cylindrical portion 212, and an outer diameter of the rubber pad 3 is larger than a diameter of an inner cavity of the thin-walled through-hole part 100, so that on one hand, a sealing effect on the first cylindrical portion 212 can be further increased, and on the other hand, interference on the machine tool tip can be effectively avoided.
Step B, providing an oil groove (not shown in the figure), injecting oil into the oil groove, immersing the thin-wall through-hole part 100 into the oil in the oil groove, so that the inner cavity of the thin-wall through-hole part 100 is filled with the oil, then providing a sealing plug 4, inserting the sealing plug into the other end of the inner cavity of the thin-wall through-hole part 100, ensuring that the inner cavity of the thin-wall through-hole part 100 is filled with the oil through matching with the extension ejector rod part 22,
in the process of machining the thin-walled through-hole part 100 from a blank to a finished product, a plurality of processes are involved, in the transferring between the working procedures and the warehousing, particularly in the trans-factory transferring, the oil coating operation is usually carried out on the parts, the invention utilizes the existing oil groove to fill oil products (rust-proof oil or lubricating oil and the like) in the inner cavity of the thin-wall through hole part 100, then the sealing plug is utilized to seal the inner cavity of the thin-wall through hole part 100, so that the inner cavity of the thin-wall through hole part 100 is filled with oil, thus, when the outer circular surface is processed, on one hand, the weight of the thin-wall through-hole part 100 is increased, can effectively avoid the situation of vibration, on the other hand, the oil filled in the inner cavity can be transferred and dispersed in the processing process of the outer circular surface, the cutting/grinding force borne by the shaft body of the thin-wall through-hole part 100 improves the processing strength and rigidity of the thin-wall through-hole part 100.
In the process of immersing the thin-wall through-hole part 100 into an oil product, the thin-wall through-hole part 100 can be horizontally placed firstly, then the thin-wall through-hole part 100 is slowly rotated under the liquid level of the oil product, so that one end provided with the ejector rod plug 2 is arranged below, the other end is arranged above, after the inner cavity of the thin-wall through-hole part 100 is filled with the oil liquid, the thin-wall through-hole part 100 can be vertically fixed, and at the moment, one end of the thin-wall through-hole part 100 to be installed can be kept above the liquid level of the oil product.

The end of the extension ejector rod part 22 is sleeved with a sealing sleeve head 23 with a U-shaped cross section, the sealing sleeve head 23 can be made of rubber or silica gel, the wall thickness can be 2-5mm, with the insertion of the sealing plug 4, when the end of the extension ejector rod part 22 is further tightly contacted with the installation guide cavity 413, the end of the extension ejector rod part 22 can be guided to be coaxial with the installation guide cavity 413, and the sealing sleeve head 23 can be deformed by the extrusion between the extension ejector rod part 22 and the inner wall of the installation guide cavity 413, so that the sealing effect is achieved, and oil in the inner cavity of the thin-wall through hole part 100 is prevented from being discharged through the guide hole 415.
Compared with the technical scheme of the application named as 'a thin-wall shaft part machining deformation control method' filed by the team of the inventor on the same day as the application, the sealing sleeve head 23 for sealing has the advantages of simple structure, low manufacturing cost and quick replacement when loss occurs.
Similar to the ejector plug 2, the diameter of the second cylindrical portion 412 may be 0.5-0.8mm smaller than the diameter of the inner cavity of the thin-walled through-hole component 100, and during assembly, the second conical body 411 may also be sleeved with an O-ring (not shown), and the maximum diameter of the O-ring is larger than the diameter of the inner cavity of the thin-walled through-hole component 100.
In order to further ensure the sealing performance during the manufacturing process, a sealing gasket with a thickness of about 2mm may be placed in the exhaust cavity 414, and then an internal nut (not shown) with an external thread is screwed into the exhaust cavity 414 to clamp the sealing gasket, so as to further ensure the sealing performance of the diversion hole 415.
The closing plug 4 may be made of metal or PET resin material.
After the sealing plug 4 is assembled in place, the inner cavity of the thin-wall through-hole part 100 can be ensured to be filled with oil after being sealed.

referring to fig. 2-5, the center positions of the ejector rod plug 2 and the sealing plug 4 are both provided with a concave portion, and when the ejector rod plug and the sealing plug are assembled, the center positions of the ejector rod plug and the sealing plug can be controlled to keep a certain distance (for example, 3-5mm) from the end surface of the thin-wall through-hole part 100, so that on a lathe such as a lathe or a grinding machine, a flat-head tip is used to avoid interference on clamping.
And D, after the outer circular surface of the step C is processed, placing the thin-wall through-hole part 100 above an oil groove, taking down the sealing plug 4 and the ejector rod plug 2, and enabling the oil product in the inner cavity of the thin-wall through-hole part 100 to flow out to the oil groove.
After the outer circular surface is machined, the closed plug 4 and the ejector rod plug 2 can be taken out through the handle rod in threaded connection, and the extension ejector rod part 22 is of a rod-shaped structure with a large length-diameter ratio, so that the ejector rod plug 2 can be taken out more conveniently after the closed plug 4 is taken down.
Thus, the machining of the outer circular surface of the thin-wall through-hole part 100 can be completed.
