Description
Technical field
The present invention relates to technical field precise polished in field of machining, specifically a kind of irregular inner hole
Polishing method.
Background technique
With the continuous development of global industry, mechanical equipment industry also continuously improves optimization, various demands in development
Spare part in mechanical equipment use also more and more, screw or plug screw in machine driving, be mainly used as components it
Between be connected and fixed or seal, install and use for convenience of certain privileged sites, screw, the plug screw product of various special shapes are just answered
It transports and life.
It can be used directly after the interior hole machined of regular tenacity or surface state screw (or plug screw) of less demanding, for table
The more demanding or more smooth inner hole of surface state or shape, especially certain productions needed through hardened by heat treatment stiffened degree or intensity
Product, the inner hole or contoured surface oxide skin after removal heat treatment are with regard to fairly cumbersome.Traditional mechanical polishing can only polish profile
Or the inner hole of the rule such as circle, and inner hole irregular for quadrangle, hexagon etc. can not then carry out.Currently, carry out
When the processing of inner hole of workpiece, for bigger inner hole, the mode for generalling use wire pulling method is realized, after processing is completed inner hole table
Helix groove can be presented in face, hereafter also need to polish bore area, to reduce the roughness on surface, improve workpiece and use
When leakproofness.Inner hole irregular for quadrangle, hexagon etc., there are certain dead angles between adjacent side, in polishing,
It is extremely difficult to ideal polishing effect, can not achieve comprehensive polishing, the disadvantages of it is low that there are polishing efficiencies, and quality of finish is poor.
In actual application, the workpiece product of various internal diameters is often used, still, for being especially structure ruler
Very little lesser product has no idea to carry out at all using conventional polishing method, such as uses electrochemical polishing method, not only polishes
Higher cost, and environment easy to pollute, workpiece size is also not easily controlled after polishing, and dimension overproof is be easy to cause to lead to product report
Useless or product surface etch pit easy to form, influences product surface shape.Therefore, it is necessary to a kind of special methods, to go
Except the oxide skin either dirt of irregular bore area, realizes automatic polishing, meet the needs of batch production processing.
Summary of the invention
The problem of for background technique, the object of the present invention is to provide a kind of easy to operate, polishing effect is good, real
Existing automatic polishing, meets the polishing method of batch production process requirements, specifically a kind of polishing method of irregular inner hole.
In order to solve the above technical problems, the technical scheme adopted by the invention is as follows: a kind of polishing method of irregular inner hole,
Steps are as follows for the polishing method:
(1), part is precast in advance by design requirement in machine tool or numerical control machining center to the high-intensitive blank of selection,
And irregular inner hole is processed by size requirement at the center of part, obtain product；
(2), oil removal treatment is carried out to the product after processing, rinses after oil removal treatment using hot water, is dried again after rinsing
Dry-cure；
(3), irregular inner hole is processed by shot blasting；
(4), cleaning and drying and processing are carried out again to the product Jing Guo polishing treatment.
Further, polishing method of the present invention, wherein the irregular inner hole processed in the step (1) is four
Side shape or hexagon blind hole.
Further, polishing method of the present invention, wherein the oil removal treatment in the step (2) uses electrochemical deoiling
Method helps washing lotion to be handled using bases, is using temperature to rinse for 80~90 DEG C of hot water after oil removal treatment, is removing bases
Washing lotion is helped, temperature is used to dry up after rinsing for 40~45 DEG C of hot-air.
Further, polishing method of the present invention, wherein the specific method of the step (3) polishing treatment is, choosing
The abrasive material and polishing fluid for being used on polishing treatment are selected, first abrasive material is added in polishing bucket, is then equably laid in product
On abrasive material, adds one layer of abrasive material again later, be then again equably laid in product on abrasive material, i.e. one layer of abrasive material, one layer of product, most
Afterwards plus one layer of abrasive material, the abrasive material weight are 5~8 times of product weight, it is desirable that the total volume of abrasive material and product is no more than polishing
The 80% of bucket total volume, is added polishing fluid later, and the additional amount of polishing fluid accounts for the 5~10% of polishing ladle capacity, adds later suitable
Calorimetric water, it is desirable that the hot water of addition flooded the abrasive material, then covered the lid of polishing bucket, was finally put into polishing bucket
It is in polishing machine and fixed, the revolving speed and polishing time of polishing machine are set, polishing machine is started, makes to polish abrasive material, polishing fluid in bucket
Lapping liquid is formed with water, is acted on the inner hole of product by lapping liquid, so that lapping liquid not only has in impact friction inner hole
Good mobility, and the grainding capacity of abrasive material is improved, so that the bore area of friction is smooth, it is highly polished, pass through polishing
Abrasive material in bucket is realized to product automatic polishing.
Further, polishing method of the present invention, wherein the abrasive material is alumina porcelain rotten-stone, the polishing fluid two
Silica polishing fluid either chromium trioxide polishing fluid.
Further, polishing method of the present invention, wherein the specific method of the step (4) cleaning and drying and processing
For first the product polished in bucket and abrasive material are poured out, is first rushed and is cleaned with cold water, product is picked out, then to the product picked out
It is rinsed 2 to 3 times using hot water, is dried again after rinsed clean.
Further, polishing method of the present invention rinses the hot water temperature that uses wherein described as 70~75 DEG C, institute
Stating drying and processing uses temperature to dry up for 40~45 DEG C of hot-air.
Using a kind of polishing method of irregular inner hole of the present invention, compared with prior art, effective effect exists
In: lapping liquid is formed using abrasive material, polishing fluid and the water in polishing bucket, is acted on the inner hole of product by lapping liquid, so that
Lapping liquid not only has extraordinary mobility, but also also improves the grainding capacity of abrasive material in impact friction inner hole, can be with
Quickly polished bore area, be effectively reduced the roughness of bore area, by friction so that bore area it is smooth,
Finish is good；Meanwhile by lapping liquid as fluid, do not influenced by the shape of product inner hole, it is applied widely, it is especially suitable
It is real using the abrasive material in polishing bucket by controlling the revolving speed and polishing time of polishing machine for the polishing treatment of small-bore inner hole
Now to the processing of product automatic polishing.In conclusion finish is good using polishing method of the present invention, polishing efficiency is high, at
This low, high reliablity operates and easy to use, easy to implement, is suitble to promote and apply, can be popularized and applied to various sizes shape
It needs to remove on the product that inner hole or irregular contour surface needs polish.
