The specific embodiment
The vacuum fixture that is used for multihole lamina processing usefulness shown in Fig. 1～5, relate to part to be processed, comprise substrate 1, positioner, gas operated device, vacuum generating device and sealing device, its special feature is: be distributed with the shallow chamber 2 that adapts with the part to be processed profile on the described substrate 1, be distributed with gas port 10 in this shallow chamber 2.Thus, shallow chamber 2 can form vacuum chamber with the part to be processed bottom surface in process, and part to be processed is adsorbed on the substrate 1.Meanwhile, positioner restriction part to be processed moving on substrate 1 makes part to be processed be in reliable clamping state to be used for machining.Gas operated device connects substrate 1 and vacuum generating device, and sealing device comprises sealing strip 9 and through hole potted component 3, and sealing strip 9 is distributed in edge, 2 surrounding, shallow chamber, and through hole potted component 3 is distributed in the shallow chamber.In other words, through hole potted component 3 is used for the sealing of the through hole on the thin plate, and both guarantee reliable absorption.
Further, be distributed with on the substrate 1 as the alignment pin 4 of mounting and positioning device promptly shown in Figure 4.One side of substrate 1 is provided with hydraulic quick coupler 8, and hydraulic quick coupler 8 connects with gas port 10, is used for connecting gas operated device.Simultaneously, the position of alignment pin 4 and size match with locating hole on the part to be processed.
Simultaneously, for the fixing better absorption of the 2 pairs of parts to be processed in shallow chamber, be distributed with the muscle and the boss 5 that adapt with the part to be processed profile in the shallow chamber 2.When part to be processed was positioned at the shallow chamber 2 of substrate 1, through hole potted component 3 was distributed in the set pilot hole of part to be processed 11 belows just.
Further combined with Fig. 3, described through hole potted component 3 comprises little axle 6 and O type circle 7 again, and the end face of little axle 6 is provided with sulculus, and O type circle 7 embeds in the sulculus, and O type circle 7 sizes and through hole size adapt.With regard to preferred implementation of the present invention, shallow chamber 2 is distributed with corresponding through hole potted component 3 at each pilot hole 11 lower position of part to be processed, guarantees that the through hole on thin plate gas leakage can not occur adding man-hour.
Specifically in conjunction with Fig. 1, this part to be processed is a multihole lamina class part, and there is shallow chamber in the front, and pilot hole 11 is arranged on it, and requirement on machining accuracy is higher.The front is a plane, and it is provided with the surface of exposing, and appearance requirement is higher.
In conjunction with Fig. 2, the positioner on the fixture substrate 1 is two alignment pins 4, is used with locating hole on the part.Shallow chamber 2 on the substrate 1 is the positive outer shape processing of mating parts, and the boss 5 that the centre is provided with is to cause distortion in order to limit part to be processed to be subjected to absorption affinity, and the vibration that produces in avoiding simultaneously cutting causes the deterioration of surperficial part to be processed quality.
Fig. 5 is the cooperating state sketch of part to be processed and vacuum fixture.The use of vacuum fixture roughly may further comprise the steps: at first, install and the cleaning anchor clamps.Subsequently, the alignment pin 4 on the locating hole line-up jig substrate 1 on the part to be processed is carefully put down.Then, make the part bottom surface touch sealing ring and impose suitable pressure.Open the vacuum generating device switch at last, make the vacuum chamber on the anchor clamps enter duty, the part bottom surface reliably contacts 1 of fixture substrate simultaneously, and part is reliably inhaled on anchor clamps dignity, finishes the clamping to part to be processed.
By above-mentioned character express also in conjunction with the accompanying drawings as can be seen, behind employing the present invention, adopt locate mode comparatively reliably, therefore can reach higher processing precision.The shape of vacuum chamber matches with part and can utilize adsorbable area to greatest extent, promptly reaches maximum adsorption power.And the vacuum fixture among the present invention belongs to special fixture, and its cutting force is little, can adopt aluminium alloy to do matrix material, and can repeatedly use after simply processing, so cost is lower.This shows, be convenient to promoting in the art.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
