Description

Vibrotumbling machine

Technical field

The present invention relates to a kind of Vibrotumbling machine, particularly relate to a kind of Vibrotumbling machine of handling goods that is applicable to at least one cavity or inner surface.

Background technology

Under the situation about particularly obtaining by the galvanic corrosion technology at least one surface, Vibrotumbling technology has been represented a kind of solution that is used to remove the economy of superficial layer.

Superficial layer is actually by galvanic corrosion and obtains, and wherein said superficial layer is hard and crisp substantially, perhaps under any circumstance for example have the microstructure and the morphological feature of not allowing for the application of particular type.

An example of such goods particularly comprises the object with at least one cavity such as rotor.

It is simple and economical by Vibrotumbling outer surface being handled, and this is because the goods that will handle are immersed in the abrasive mixture.

Goods are maintained in the container, described container and then be subjected to the effect of vibrating device and produce vibration.

It is not hard especially material composition, abrasive grain, water and additive for the common of " medium " that abrasive mixture generally comprises multiple known english term.

Various material compositions, i.e. medium, function be to transmit kinetic energy to abrasive grain so that these material compositions bump against on the goods that will handle.

The abrasive grain that each medium composition is present in the abrasive mixture surrounds, and by the vibration of described container reception from vibrating device.

In this manner, the various compositions in the abrasive mixture bump against on the outer surface of the goods that will handle, cause the abrasive grain described same surface that rubs.

By the described surface that rubs, described particle causes the removal of material on the outer surface of goods, thereby produces the wearing and tearing of superficial layer and material from wherein removal.

Therefore, oscillating movement is endowed and is used for Vibrotumbling in the market or vibrates accurately machined abrasive mixture machine, and this oscillating movement is delivered to the goods that will handle or the surface of equating thereafter.

In other words, vibration is delivered to the goods that will handle by abrasive mixture, and wherein said goods are immersed in the abrasive mixture fully; Described abrasive mixture is maintained in the container that is vibrated.

Described vibration and then be delivered to abrasive mixture, and therefore be delivered to described goods.

The vibration that causes abrasive mixture by vibrating device produces the relative motion of abrasive mixture with respect to the product surface that will handle exclusively.

Therefore a shortcoming of current machine is: because described abrasive mixture does not flow in described internal cavities, therefore cause producing so-called " embolism " effect, make this relative motion minimizing or complete obiteration in groove, opening, cavity and narrower fin.

Because use existing machine can not realize abrasive mixture and the effective relative motion between the unapproachable pending product inner surface usually, it is impossible therefore described inner surface effectively being handled.

Can cause like this: because by the abrasive action of abrasive mixture described inner surface to be handled is impossible, therefore be necessary usually to obtain product by different technology, common like this have a higher operating cost, also can cause quality to reduce simultaneously.

Even, can not effectively handle inner surface when using vibration during abrader, the inner surface of groove and particularly for example in some rotors, have the inner surface in the thin chamber of narrower section for example.

In this case, friction energy when lapping device arrives described inner surface, perhaps worse situation is to be maintained at described groove or cavity inside.

In both of these case, can not obtain abrasive mixture in the useful effect of passing through on the quite thin and narrow accessible described inner surface of section, wherein the scope of section minimum of a value is the 5-10 millimeter.

Another shortcoming is: under any circumstance, for wideer section, mainly at the place, outside near the product that will handle, described surface is subjected to uneven grinding.

This is because the change of direction and speed causes frequency and the impact strength of higher abrasive mixture composition on object.

Summary of the invention

Even if the object of the present invention is to provide a kind of when for example groove, cavity, case and hole etc. are thin and narrow, the also Vibrotumbling machine that can handle its inner surface.

Another object of the present invention is to produce a kind of Vibrotumbling machine that can remove material from least one inner surface of the goods that will handle equably with at least one cavity or indenture.

Another purpose of the present invention is to provide a kind of Vibrotumbling machine of can be effectively and equably inner surface and outer surface being handled.

Another purpose of the present invention is to provide a kind of simple and economic Vibrotumbling machine.

These targets according to the present invention realize as technical scheme 1 described Vibrotumbling machine by producing.

Other technical characterictic of the present invention has been shown in other technical scheme subsequently.

Described pressure apparatus preferably includes the abrasive mixture cylinder that is positioned at described goods 18 tops, and is mobile relatively thereby pressurization produces with respect to the same part near the abrasive mixture of goods 18, so that remove material from it equably.

Simultaneously, supply with commercial abrasive mixtures (preparation, abrasive product, water, additive) by rubber gatherer 62 to described rotor 18 as shown in Figure 3, described rubber gatherer receive from conveyance conduit 61 that the storage tank 60 that is suspended on about 1000 millimeters tops links to each other in mixture.

According to a preferred embodiment, described machine 10 preferably includes framework 12, and described bar 20 is by elastic device 40, and for example particularly a succession of spring is constrained on the described framework 12.

Described bar 20 preferably is constrained on 21 places, first upper end of described framework 12 by a succession of vertical guide member 45 and is suspended on the described framework by described elastic device 40, and described elastic device allows described bar 20 to carry out relative motion with respect to described framework 12 in the vertical directions.

Described vertical bar 20 also has a bottom 22, and on described bottom 22, described rotor 18 is tightened, and described upper end 21 for example particularly is connected to its non-equilibrium motor 30 that transmits vibration with vibrating device.

Described motor 30 is preferably placed at described framework 12 tops and described motor 30 preferably is constrained on the described upper end 21 of described bar 20 by the disk 24 with described bar 20 one.

This vibrating device directly is associated with the system 18 that will handle thus, and therefore can not have the attenuation of any kind to its transmission vibration.

Described machine 10 preferably includes in order in described at least one cavity that described mixture is imported described goods 18 or be sent to rubber gatherer 62 above it.

Described pressure apparatus preferably includes storage tank 60 and conveyance conduit 61, described conveyance conduit 61 comprises first end and the second end, described first end is positioned at the downstream of described storage tank 60, and described the second end is positioned at the upstream of described goods 18, thereby allows abrasive mixture to flow with respect to described goods 18.
