The specific embodiment
See also Fig. 1 to Fig. 3, the adsorbent equipment 10 that the utility model one preferred embodiment is provided is to include ring 30, one plug parts 40, one outer shrouds 50 in the board 20,, and an aeroscopic plate 60.
This board 20 has the end face 201 and bottom surface 202 that most through holes 22 are communicated with this board 20, this through hole 22 has a minor diameter part 23, one large-diameter portion 24, and one shoulder 25 between this minor diameter part 23 and large-diameter portion 24, this board 20 is also can not be subjected to the material (as aluminium) of magnetic attraction made by not having magnetic force.
Should interior ring 30 be to be located in these through hole 20 large-diameter portions 24 and to paste to be butted on this shoulder 25, this interior ring 30 has an axis hole 32 and is communicated with the minor diameter part 23 of this through hole 20, the outer rim of ring 30 is then closely pasted the inner edge that is butted on this large-diameter portion 24 in being somebody's turn to do, in addition, should be provided with the bottom that a conical surface 34 is positioned at this axis hole 32 by interior ring 30, ring 30 is to be made by the material with magnetic (as magnet) in being somebody's turn to do in present embodiment.
This plug spare 40 is to be spheroidal and to be located in these through hole 22 large-diameter portions 24, this plug spare 40 is made by the material that can be subjected to magnetic attraction (as iron), make this plug spare 40 and should in ring have magnetic force between 30 and can attract each other and link together so that should in the axis hole 32 of ring 30 fill in part 40 for this and sealed.
This outer shroud 50 is bottoms of being located at these through hole 20 large-diameter portions 24, this outer shroud 20 also has an axis hole 52, be communicated with this through hole 22 with extraneous, the outer rim of this outer shroud 50 is then closely pasted the inner edge that is butted on this large-diameter portion 24, these axis hole 52 tops also are provided with a conical surface 54, and this outer shroud 50 also is also can not be subjected to the material (as aluminium) of magnetic attraction made not have magnetic force.
This aeroscopic plate 60 is the bottom surfaces 202 that fit in this board 20, extremely shown in Figure 4 as Fig. 2, these aeroscopic plate 60 surfaces are provided with most grooves of arranging in length and breadth 62 and are communicated with the axis hole 52 of this outer shroud 50, then be provided with an air flue 64 in this aeroscopic plate 30 and be communicated with this groove 62 with extraneous, the outlet of this air flue 64 then is provided with a joint 66, can connect for exhaust pipe to establish.
By this, when workpiece to be processed 70 is placed on this board 20, the through hole 22 that is capped as shown in Figure 3, because the magneticaction that this plug spare 40 and this interior ring are 30 was attached together the two, air will be via the slit of this workpiece 70 with this board 20, this minor diameter part 23, should interiorly encircle 30 axis hole 32, should fill in the slit of part 40 with this by interior ring 30, the axis hole 52 of this outer shroud 50, this groove 62 and this air flue 64 are detached (as shown by arrows), make the air pressure (atmospheric pressure) of the air pressure of these workpiece 70 bottom surfaces 71, utilize this draught head workpiece firmly can be positioned on this board 20 much smaller than end face 72; Need to prove that though this is attractive between filling in part 40 and should interiorly encircling 30, the pressure differentials inside and outside right this plug spare 40 are enough to the two separation is produced the slit.
Review the through hole 22 that other are not covered by workpiece 70, then as shown in Figure 5, because these through hole 22 not cresteds of minor diameter part 23, so a large amount of air pour into the axis hole 32 that directly encircles 30 by this minor diameter part 23 and in being somebody's turn to do in this through hole 22, the kinetic energy of flow at high speed gas will overcome this plug spare 40 and should interiorly encircle 30 attraction, this plug spare 40 is separated with ring 30 in this, the impact power of gas will force this plug spare 40 to paste the conical surface 54 that is butted on this outer shroud 50 simultaneously, utilize this plug spare 40 inside and outside pressure differentials can make this plug spare 40 tightly paste the conical surface 54 that is butted on this outer shroud 50, can reach seal degree with existing process technology, so can eliminate gas leak phenomenon herein.
In other words, the through hole 22 that is covered by workpiece 70 can provide the strength of absorption via bleeding, not the through hole 22 that is covered by workpiece 70 (the perhaps through hole 22 of workpiece 70 and board 20 gap larger parts) though moment have a large amount of gas leakage, so in the utmost point in the short time high velocity air can make this plug spare 40 be resisted against the conical surface 54 of this outer shroud 50, gas leak phenomenon is almost disappeared, so, this adsorbent equipment 10 can be according to the size or the shape difference of workpiece, automatically adjust the position of plug part 40 in each through hole 22, avoid gas leak phenomenon, improve the vacuum of board 20 belows simultaneously, can effectively promote the operating efficiency of adsorbent equipment, really can improve the disappearance of prior art structure, thereby reach the purpose of this utility model.
What deserves to be mentioned is, according to spirit of the present utility model, as long as between ring 30 and this plug spare 40 the pre-power that abuts against is mutually arranged in being somebody's turn to do, this pre-power can utilize this interior ring 30 to reach with the material of this plug spare 40, also can utilize structural design to form, for example: can select the two to be and have the magnetic material and make, perhaps only wherein one make for magnetic material, and another person is in the utility model and please contains by claim for made by the material of magnetic attraction.
By ring in forming by structural design and the pre-power between part of filling in then as Fig. 6, shown in Figure 7, it is the utility model adsorbent equipment 80 that preferred embodiment provided in addition, also include a board 82, one interior ring 84, one plug part 86, an outer shroud 88 and an aeroscopic plate 90, different being in this outer shroud 88 be provided with the top that a holding part 89 is positioned at its axis hole 881, use for an elastic component 92 bottoms ccontaining and this elastic component 88 of confession and replace, the top of this elastic component 92 then is resisted against this plug spare 86, this plug spare 86 is provided and should interiorly encircles the pre-power that abuts against mutually between 84.
By this, when the through hole 83 of this board 82 is covered by workpiece 94, as shown in Figure 6, air is drawn out of direction as shown by arrows, the situation that is not capped through hole 83 then as shown in Figure 7, swiftly flowing gas will overcome the elastic force of this elastic component 92, force this plug spare 86 to paste the conical surface 882 that is butted on this outer shroud 88, to eliminate gas leak phenomenon.
