Description
Technical field
The present invention relates to technical field of mechanical processing, and in particular to a kind of air water for being machined clamping vacuum cup point
From structure.
Background technology
It is a kind of common installation way using vacuum cup absorption clamping workpiece in field of machining, vacuum cup
Structure design and use are generally concerned with three points：Effective vacuum chamber projected area, sucker and clamping workpiece adsorb location type face
Face type fit precision, vacuum sealing performance, its core paid close attention to are the workpiece deformation of vacuum suction, vacuum leakproofness (vacuum
Degree), but be machined and use under fluid conditions, the sealing between sucker and workpiece can not possibly reach 100%, and no system is examined
Consider micro or a small amount of coolant into after sealing surface, when dismantling workpiece, sucker clamping workpiece is positioned appearance quality and
The influence fast dismantled：
1st, usually require to use coolant in machine cut process, coolant is in process because pull of vacuum is made
With sealing surface (sucker and workpiece positioning surface) is entered, forming local or liquid film in flakes, each liquid film part unicom can form small
Vacuum chamber, when dismantling workpiece, small vacuum chamber residual suction is common between liquid film surface tension (Molecular Adsorption power), liquid film
Under effect, workpiece is relatively difficult to remove perpendicular to suction cup sealed face direction.At this moment, if can be when being removed using lateral movement workpiece
Workpiece surface causes cut or scuffing；If workpiece method is gone out, it is necessary in vacuum using compressed air by vacuum line
Increase compressed air line in gas circuit design, need the careful pressure and speed for adjusting compressed air, and this kind of method is in work piece vertically
During formula machining state, can cause under workpiece gravity large-scale workpiece compressed air effect under, occur it is unstable rush with
Fall, cause workpiece local and sucker collides with phenomenon, seriously affect surface quality.
2nd, in continuous vacuum suction clamping process for a long time (more than 0.5h), coolant, powdered chip (especially work
When part is nonmetallic materials) penetrate into minor gap between suction cup sealed face and workpiece positioning surface, some components of coolant, fine cut
Bits can be enriched with vacuum cup sealing surface especially vacuum chamber outer ledge, form the extremely strong deposit of certain degree of hardness, adhesive force,
The focal adhesion of sucker and workpiece is caused, when dismantling travelling workpiece, causes workpiece surface damage, and deposit is more difficult clear
Reason is, it is necessary to use specific purpose tool or solvent.
The content of the invention
The present invention overcomes the deficiencies in the prior art, during to solve traditional vacuum sucker suction clamping workpiece, because of coolant
The problem of workpiece surface quality and quick dismounting are influenced when mixing liquid causes workpiece to dismantle into vacuum chamber, the present invention provides
A kind of gas-water separation structure design for being machined clamping vacuum cup, by the design by sucker vacuum pneumatic passage and cold
But liquid channel separation, has prevented the mixing liquids such as coolant and has entered vacuum chamber.
To solve above-mentioned technical problem, the present invention uses following technical scheme：
It is a kind of be machined clamping vacuum cup gas-water separation structure, the gas-water separation structure mainly by venthole,
Water proof chamber and cutoff collar composition；The venthole is arranged on the water proof intracavitary, and the venthole is formed with the water proof chamber
Gas circuit, and it is combined into vacuum air-channel with sucker vacuum chamber and suction cup sealed face；The cutoff collar is located at sucker suction end, with suction
Disk vacuum chamber has interval, forms water proof face.
Further technical solution is to further include splash-guard ring, and the splash-guard ring is the protrusion positioned at sucker outer mold surface lower part
Structure.
Further technical solution is that the gas-water separation structure is located at sucker vacuum chamber and contacts side with coolant.
Further technical solution is that the gas-water separation structure is arranged in suction when the sucker vacuum chamber is pass
On the outside of disk vacuum chamber；When the sucker vacuum chamber is annular, the gas-water separation structure is arranged in the sucker vacuum chamber two
Side.
Further technical solution is that the venthole is to be distributed on the water proof intracavitary.
Further technical solution is that the ventilation bore dia is not less than 2 millimeters, and quantity is no less than 6.
Further technical solution is that the water proof chamber is located at sucker both ends, width of the water proof chamber positioned at absorption end
It is not less than 2 millimeters with depth；The depth that the water proof chamber is located at sucker rear portion is not less than 4 millimeters.
Further technical solution is the cutoff collar end face and suction cup sealed face is same continuous type face.
Further technical solution is that cutoff collar end face width is 2 to 3 millimeters；The machined surface profile of the cutoff collar
Degree is less than 0.01mm.
Further technical solution be when for horizontal machining state when, the overhang of the splash-guard ring is not less than 5 millimeters.
Compared with prior art, one of beneficial effect of the embodiment of the present invention is：The vacuum cup of the present invention passes through by leading to
The ingenious and simple design of stomata, water proof chamber, cutoff collar, splash-guard ring, constitutes gas-water separation structure, has thoroughly prevented processing
During the mixing liquid such as coolant the problem of penetrating into sealing surface and vacuum chamber, can be directly quick leggiero with perpendicular to sucker
The direction dismounting workpiece of sealing surface, solves liquid film remnants adsorption capacities caused by coolant is penetrated into, evaporate relict sediment
The influence dismantled during dismounting to workpiece surface quality and fast.The gas-water separation structure is suitable for the machinery such as plane, shaped face and adds
Frock presss from both sides absorption vacuum cup.
