Description
Technical field
This utility model relates to a kind of rare earth permanent-magnetic material processing equipment equipment field, is specifically related to a kind of vacuum cup fixture for permanent magnet material mill processing.
Background technology
Much more typically grinding machine is used during rare earth permanent-magnetic material machining, rare earth permanent-magnetic material particularly sintered NdFeB, a large amount of employing surface grinding machines processing.No matter it is square platform surface grinding machine or rotary grinder, is all to use magnechuck to fix product and fixture.It is fixing that product adds the absorption of many employings in man-hour magnetic suction disc on grinding machine.Magnechuck can make product be magnetized, and after processing, product is with the presence of residual magnetic field, then electromagnetism demagnetization or heat are demagnetized.Not exclusively, heat demagnetization product surface easily produces etch pit and oxidation in electromagnetism demagnetization.These all can affect electrodeposited coating quality.Also employing clamp for machining is had to fix product, it is simply that to add a magnetic field shielding plate between disk and product, weaken the magnetic field magnetization to product, but product to be processed chucking power can be made to reduce simultaneously, impact processing feed velocity, product form and position tolerance precision reduces, and working (machining) efficiency is slack-off.
Summary of the invention
For above-mentioned situation, this utility model provides a kind of negative-pressure vacuum fixture, makes product reach without magnetic processing and ensure machining accuracy, the device of efficiency.
The technical scheme that this utility model is used is as follows:
A kind of vacuum cup fixture for permanent magnet material mill processing, is made up of sucker body and sucker base, and this internal annular groove that is provided with of described sucker is evenly equipped with vacuum through holes in annular groove；Described sucker base is provided with air-breathing groove, and the bottom of described air-breathing groove connects aspirating hole, and aspirating hole is located at the side of sucker base, and described aspirating hole connects vacuum pump；Described sucker body is placed on described sucker base, and the vacuum through holes in annular groove is corresponding with the air-breathing groove of lower section.
Described sucker body can be positive limit shape or circle.
Described air-breathing groove is H type.
Described vacuum pump 7 uses water circulation vacuum pump.
The outer diameter D size of described annular groove is more than annular products outer diameter D ' size 0-0.1 millimeter, the internal diameter d of annular groove is smaller in size than product internal diameter d ' size 0-0.1 millimeter, and annular groove degree of depth A is more than product thickness 1/2nd and less than product thickness.
When described vacuum pump 7 is opened, form the depth H size of absorption annular recess of vacuum more than 1 millimeter, absorption annular recess external diameter C is smaller in size than annular groove outer diameter D size 5-10 millimeter, and absorption annular recess internal diameter F size is more than annular groove internal diameter d size 5-10 millimeter.
The quantity of described sucker body and described sucker base designs according to lathe table top size, it is achieved more than one piece product is processed simultaneously.
Beneficial effect: this utility model uses negative-pressure vacuum fixture to fix product, it is to avoid product is magnetized, beneficially during subsequent product plating, improve product surface cleannes, coating uniformity when improving plating, eliminates the residual magnetic field impact on coating, improves binding force of cladding material.

Detailed description of the invention
As shown in Figure 1, a kind of vacuum cup fixture for permanent magnet material mill processing, described sucker body 1 is placed on described sucker base 4, vacuum through holes 3 in annular groove 2 is corresponding with the air-breathing groove 5 of lower section, both are unimpeded, when opening vacuum pump 7, negative pressure can hold the product being placed on sucker body 1.Airflow direction is as shown by the arrow.Negative-pressure vacuum degree can be in 80kP ~ 5kP (absolute pressure).
As Figure 1-3, sucker body 1 can be positive limit shape or polygon, or circular, this internal annular groove that is provided with of described sucker, is evenly equipped with vacuum through holes in annular groove；
The outer diameter D size of annular groove is more than annular products outer diameter D ' size 0-0.1 millimeter, the internal diameter d of annular groove 2 is smaller in size than product internal diameter d ' size 0-0.1 millimeter, and annular groove 2 degree of depth A is more than product thickness 1/2nd and less than product thickness.
When opening vacuum pump 7, form the depth H size of absorption annular recess of vacuum more than 1 millimeter, absorption annular recess external diameter C is smaller in size than annular groove 2 outer diameter D size 5-10 millimeter, and absorption annular recess internal diameter F size is more than annular groove 2 internal diameter d size 5-10 millimeter；
As illustrated in figures 4-5, described sucker base 4 is provided with air-breathing groove 5, and described air-breathing groove 5 is H type, the bottom of described air-breathing groove 5 connects aspirating hole 6, aspirating hole 6 is located at the side of sucker base 4, and described aspirating hole 6 connects vacuum pump 7, and described vacuum pump 7 uses water circulation vacuum pump.
Above-mentioned vacuum pump 7 can replace with other equipment that can produce negative-pressure vacuum.
In order to adapt to Production requirement, sucker body 1 and sucker base 4 can design according to lathe table top size, it is achieved more than one piece product is processed simultaneously.
