Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is described in detail, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
Shown in attached Fig. 1 and 2, the absorption tool of internally provided with vacuum generator of the present utility model comprises working plate 1, vacuum generator 2, snap joint 3, shunt fast 4, the first tracheae 5, L-type joint 6, gold utensil 9, sucker 10, gulde edge 11 and locating dowel 12, each parts is installed in respectively on the inside and surface of working plate 1, wherein vacuum generator 2, snap joint 3, shunt fast 4, the first tracheae 5, L-type joint 6 is positioned at the inside of working plate 1, snap joint 3 ports are drawn from working plate 1 one sides, the compressed air gas source of convenient external steady pressure, gold utensil 9, sucker 10, gulde edge 11, locating dowel 12 is positioned on the surface of working plate 1.Vacuum generator 2 links to each other with the compressed air gas source of extraneous steady pressure by the snap joint 3 that is attached thereto, and be connected with branching block 4, be connected with 4 the first tracheaes 5 on the branching block 4, each the first tracheae 5 port is connected to L-type joint 6, working plate 1 is provided with 4 through holes, through hole one end dress L-type joint 6 is connected to branching block 4 by the first tracheae 5, the other end is equipped with gold utensil 9, assembling sucker 10 on the gold utensil, have 4 suckers 10, be provided with 1 gulde edge 11 and 2 locating dowels 12 at working plate 1 absorption locating surface.
The absorption tool of internally provided with vacuum generator of the present utility model is the absorbent-type tool, in the face of clamping yielding or during workpiece that can't clamping, can adsorb very easily fixing and can not cause that the workpiece damage is out of shape.
Take this absorption tool workpiece is fixed on the five axle polishing machines as example and is illustrated, the specification of vacuum generator 2 is: operating pressure 5kgf/cm
2Be fit to voltage AC125V, 5A or AC250V, 3A; Vacuum pressure-91.8kPa(-690mmHg); Air consumption 44Nl/min can select the AC power of different operating voltage, so that this absorption tool can be used widely, only take the vacuum generator of this specification as example, but is not limited to this.Surface of the work needs all processing, and the snap joint 3 that working plate 1 one side sides are drawn links to each other with the compressed air gas source of external stabilization pressure, opens source of the gas, continues to pass into pressure 5kgf/cm
2Compressed air, entrainment mobile in vacuum generator 2 interior generations, under the effect of entrainmenting, air in the chamber constantly is sucked away, Pressure Drop in the chamber is to atmospheric pressure, produce negative pressure, because branching block 4 is connected with vacuum generator 2, just produced negative pressure in the branching block 4, be transmitted on the sucker 10 of assembling on the gold utensil 9 by the first tracheae 5 of being connected and L-type joint 6 effect with negative pressure, sucker 10 acts on the bottom of workpiece, and absorption of workpieces on the tool surface, has so just been limited the free degree of workpiece above-below direction; Absorption tool surface is provided with 1 gulde edge 11 and 2 locating dowels 12, and two set locating holes are arranged on the processing work, workpiece is installed on the tool, its locating hole is alignd with the locating dowel 12 of absorption tool, workpiece can limit the rotary freedom of workpiece on the absorption tool on one side near gulde edge 11 by this cooperation, then by sucker the workpiece bottom is firmly adsorbed, so just can and be fixed on the absorption tool the workpiece location, can carry out polishing to the whole surface of workpiece.
Because negative pressure pressure is the assurance of adsorption effect, also being provided with respectively one detects plunger 7 and detects plunger baffle plate 8, detecting plunger 7 is connected with branching block 4 by the second tracheae 13, detecting plunger 7 when producing negative pressure can be inhaled into, if negative pressure is not enough or when not producing negative pressure, detecting plunger 7 will can not sucked fully or can not be inhaled into, this action that detects plunger 7 can conveniently judge whether to produce enough negative pressure and whether inside has fault by observing, can guarantee that workpiece is adsorbed on the frock clamp fully, detect plunger baffle plate 8 and play the effect that detects plunger 7 that stops, restriction detects the operating position of plunger 7.Perhaps be provided with a vacuum meter in working plate 1 side, be connected with branching block 4 by the second tracheae 13, directly judge whether to produce enough negative pressure by the in good time force value that reads vacuum meter and whether inside has fault.
For the workpiece of stock size, be connected with 2 the first tracheaes 5 on the branching block 4,2 suckers 10 are housed accordingly, just it can be absorbed and fixed at absorption tool surface by 1 gulde edge 11 and 2 locating dowels 12 of adsorbing the tool surface.And for larger-size workpiece, the quantity that then correspondingly needs to increase sucker 10 and locating dowel 12 could be fixed in good absorption, need to consider these factors and be adjusted in actual design.
Locating dowel 12 is the removable and replaceable type, the bottom cooperates the locating dowel 12 that guarantees replacing to have interchangeability with jig tool equipment plate 1 by degree of precision, after locating dowel 12 heavy wears, do not need to change a whole set of tool and only need change locating dowel 12 and get final product, fast and easy has also reduced cost.
Workpiece has cutting fluid man-hour and is sprayed on bistrique and the workpiece adding, lower the temperature, air inlet pipe hole position on working plate and detect position, hole, plunger place and be provided with rain visor or guiding gutter prevents that cutting fluid from entering tool inside, so that this absorption tool has fabulous water proofing property.
In sum, the employing internally provided with vacuum generator of the utility model embodiment substitutes the absorption tool of traditional external vavuum pump, it can be yielding to clamping, can't clamping or the surface need the workpiece of all processing adsorb the location, the absorption location that is particularly useful for weak workpiece, owing to substituted traditional vavuum pump with vacuum generator, small and exquisite vacuum generator can place in the working plate, so that whole absorption tool can integrated design, superior performance, attractive in appearance proper.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that does not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any Reference numeral in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme among each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
