Abstract
The present invention relates to laminar mechanical parts Surface-micromachining process fields, the blade surface processing method of specifically a kind of propeller and the wall outer surface processing method of U-shaped part, it is intended to solve existing relatively thin propeller blade and U-shaped the feature side-wall technical problem that vibration is big when surface processes, precision is low.Concrete scheme is as follows: when processing the side wall of blade or U-shaped part, first beat table record base value, then filling flexible adhesive material in the space between adjacent two blade or side wall, until blade struts outward under the action of the power of flexible adhesive material, and table is played in the work surface dial gauge of blade or side wall and guarantees that the distracted amplitude of blade in the range of it can spring back, is then processed.In this way using the performance of flexible adhesive material, it can effectively reduce vibration and allow knife, improve machining accuracy.
Description
Technical field
The present invention relates to laminar mechanical parts Surface-micromachining process field, the blade surface of specifically a kind of propeller is processed
The wall outer surface processing method of method and U-shaped part.
Background technique
Propeller is to rotate in air or in water, converts engine rotation power in the device of propulsive force, such as Fig. 1 institute
Show, be generally made of wheel hub 1 and blade 2, is widely used in the propeller of aircraft, steamer.The efficiency of propeller is by diameter, blade
The influence of the geometric parameters such as number, solidity, blade angle.Propeller material mainly uses aluminium alloy.With the promotion of properties of product
With the raising of lightweight requirements, in order to further increase propeller efficiency, propeller is gradually to major diameter, slim vane, Gao Chonghe
The direction of degree is developed.Here it is overlapped and refers to that edge sees that two blades have the part mutually blocked perpendicular to the direction of blade, the portion blocked
Dividing is the part being overlapped.This blade is using traditional processing method since blade face allowance is few, and blade is thin, arm length, rigidity
Wretched insufficiency is vibrated and makes knife serious when processing, can not effectively be processed, precision is difficult to ensure.
U-shaped part, in machinery field also more typically, as shown in Fig. 2, generally by two opposite side walls 3 and connection two
The interconnecting piece 4 of side wall forms.The sidewall thickness of partial U-shape part is relatively thin, between 1-2mm, appearance when processing the outer surface of side wall
It is also easy to produce vibration, roughness is difficult to ensure that machining accuracy is lower, or even can not process.
Summary of the invention
Present invention seek to address that the vibration when surface processes of existing relatively thin propeller blade and U-shaped feature side-wall is big, essence
Spend low technical problem.For this purpose, the present invention proposes following two method:
A kind of blade surface processing method of propeller, the long 100-200mm of the blade, thickness 0.2-1mm, adjacent two blade are formed
There are the part of coincidence, including following procedure of processing:
S1, fixed propeller, play table in the work surface dial gauge of blade, and record reading；
Filling flexible adhesive material in S2, the space between adjacent two blade, until power of the blade in flexible adhesive material
It is strutted outward under effect, and plays table in the work surface dial gauge of blade and guarantee that the distracted amplitude of blade can be sprung back at it
In the range of (amount of flexible adhesive material guarantees that the deformation of its caused blade can restore, according to front and back two when specific detection
The rebound range of the difference of secondary dial gauge and the blade standard compares, and the rebound range of blade standard is by repeatedly trying
Test that you can get it)；
S3, successively the outer surface of this group of blade is carried out being machined to complete using sintered carbide ball knife；
S4, flexible adhesive material is dismantled, and chooses another group of blade, repeat S1-S3 step, until the surface of all blades all adds
Work is completed.
The sidewall thickness of a kind of wall outer surface processing method of U-shaped part, the U-shaped part is 1-2mm, including following
Procedure of processing:
S1, fixed U-shaped part, play table with dial gauge in the outer surface of its side wall, and record reading；
Filling flexible adhesive material in S2, the space between two sidewalls, until work of the two sidewalls in the power of flexible adhesive material
It is strutted outward with lower, and beats the range that the table guarantee distracted amplitude of side wall can be sprung back at it in the outer surface dial gauge of side wall
It is interior that (amount of flexible adhesive material guarantees that the deformation of its caused side wall can restore, according to front and back percentage twice when specific detection
The rebound range of the difference of table and the side wall standard compares, and the rebound range of side wall standard passes through test of many times
It obtains)；
S3, successively the outer surface of two sidewalls is carried out being machined to complete using sintered carbide ball knife.
The beneficial effects of the present invention are:
The present invention provides the method for surface finish of a kind of propeller blade and U-shaped feature side-wall, and blade or side wall are relatively thin, and surface adds
Working hour, the filling flexible adhesive material between blade or side wall, and due to the viscosity of flexible adhesive material, two blades can be made
As an entirety, blade construction rigidity can be effectively improved, reduction allows knife and vibration；Since the elasticity of flexible adhesive material is made
With can play the role of an elastic force to blade, blade can be sprung back in time after stress, and reduction allows knife, guarantee the size essence of processing
Degree has the function of absorbing vibration；In addition, the amount of flexible adhesive material guarantees that blade or side wall support simultaneously outside by a small margin in the present invention
And in the range of being maintained at and capable of springing back, can further decrease generated in processing allow knife phenomenon, improve machining accuracy；Due to
It reduces vibration and allows knife, cutting data can suitably increase, and effectively increase processing efficiency.
