Abstract

The utility model discloses a durable anodizing fixture. The durable anodizing fixture comprises a metal fixture main body, wherein a sunk groove is formed at a hanging part used for hanging a workpiece on the metal fixture main body, a conductive metal block is contained in the sunk groove, an insulation antioxidation film is coated on each of the surface of the fixture main body and the outer surface of the sunk groove, a sunk hole is also formed below the sunk groove, a conductive metal cylinder extends out from the lower end of the conductive metal block and is inserted into the sunk hole, and an acid solution isolation gasket is sheathed on the conductive metal cylinder. The durable anodizing fixture disclosed by the utility model has the advantages that the effect of preventing oxidization of electrolyte is achieved by coating the antioxidation film on the surface of the fixture; and electric conduction is realized by inserting the conductive metal cylinder of the conductive metal block into the sunk hole which is not coated with the antioxidation film; the acid solution isolation gasket can prevent the electrolyte from permeating into the sunk hole, so that the electric conduction effect can not be influenced; and the conductive metal block is small in size, pollution to the electrolyte can be ignored, and the conductive metal block can be polished in a centralized manner after being oxidized; and the conductive metal block is small in size and easy to polish, so that replacement cost is low, and service life of the whole fixture is prolonged.

Description

A kind of durable type anodic oxidation fixture

Technical field

The utility model relates to a kind of frock clamp, a kind of especially fixture for aluminium alloy anode oxide.

Background technology

The purpose of aluminium alloy anode oxide is to strengthen surface hardness, wear resistance and the erosion resistance of Al alloy parts.In anodised process, workpiece is hung up on fixture, be immersed in electrolytic solution, utilize electrolytic action, form aluminum oxide film at workpiece surface.The anodic oxidation of using is at present adopted the hard aluminium alloy materials with the fixture majority, when being immersed in together in acid solution with workpiece, in the oxidized process of workpiece, fixture itself also can be progressively oxidized, and the oxidation of fixture, can pollute electrolytic solution on the one hand, on the other hand, need the zone of oxidation on frequent grinding clamp surface in order to realize good conductivity, will make like this fixture more and more thinner, reduction of service life, and the batch replacement fixture need to consume a large amount of costs.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of durable type anodic oxidation fixture.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of durable type anodic oxidation fixture, comprise the metal fixture main body, the place, extension position that is used for the suspension workpiece on described main body has lower deep gouge, described lower deep gouge content is equipped with the conducting metal piece, the top layer of described jig main body and the outside surface of described lower deep gouge are coated with the anti-oxidant rete of insulation, described lower deep gouge below also has counterbore, and described conducting metal piece lower end is extended conducting metal cylinder plug-in mounting and entered in described counterbore, and described conducting metal cylinder is set with the acid solution cage ring outward.

Described acid solution spacer ring is between described conducting metal piece and described lower deep gouge end face, and described acid solution spacer ring is silicon rubber loop.

The beneficial effects of the utility model are: the utility model reaches by the anti-oxidant rete of fixture top layer coating insulation the effect that stops electrolyte oxidation, simultaneously, for realizing the conduction of workpiece, at the embedded dress conducting metal of the lower deep gouge piece of hanging the place, position, the cylinder of conducting metal piece extend in the counterbore of uncoated oxidation-resistant film; The acid solution spacer ring can stop electrolytic solution to penetrate in counterbore, affects conductive effect.Because the conducting metal block is long-pending little, pollution to electrolytic solution can be ignored, can concentrate polishing after the conducting metal piece is oxidized, and oxide side is regular, volume is little, polishing is easy, even need to change after long-time the use, its cost all reduces for changing whole fixture greatly, and simultaneously, can greatly extend the work-ing life of integral clamp.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of a kind of embodiment of the utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 splits schematic diagram in Fig. 2.

Embodiment

With reference to Fig. 1, a kind of durable type anodic oxidation fixture, comprise metal fixture main body 1,2 places, extension position that are used for the suspension workpiece on described main body 1 have lower deep gouge 3, be equipped with conducting metal piece 5 in described lower deep gouge 3, the outside surface of the top layer of described jig main body 1 and described lower deep gouge 3 is coated with the anti-oxidant rete 7 of insulation, described lower deep gouge 3 belows also have counterbore 4, described conducting metal piece 5 lower ends are extended conducting metal cylinder 51 plug-in mountings and are entered in described counterbore 4, the outer acid solution cage ring 6 that is set with of described conducting metal cylinder 51.

Conducting metal piece 5 can adopt the titanium alloy piece, and intensity is high and be difficult for oxidation; The anti-oxidant rete that insulate can adopt the insulation oxidation resistant coating such as poly tetrafluoroethylene.

The utility model reaches by the anti-oxidant rete 7 of fixture top layer coating the effect that stops electrolyte oxidation, simultaneously, for realizing the conduction of workpiece, at the interior setting-in conducting metal of lower deep gouge 3 piece 5 of hanging 2 places, position, the cylinder 51 of conducting metal piece extend in the counterbore 4 of uncoated oxidation-resistant film; Acid solution spacer ring 6 can stop electrolytic solution to penetrate in counterbore 4, affects conductive effect.Because conducting metal piece 5 volumes are little, pollution to electrolytic solution can be ignored, can concentrate polishing after conducting metal piece 5 is oxidized, and oxide side is regular, volume is little, polishing is easy, even need to change after long-time the use, its cost all reduces for changing whole fixture greatly, and simultaneously, can greatly extend the work-ing life of integral clamp.

As preferred implementation of the present utility model, described acid solution spacer ring 6 adopts silicon rubber loop, has elasticity, and between described conducting metal piece 5 and described lower deep gouge 3 end faces, long seal isolation length can be arranged, and guarantees the seal isolation effect.

The utility model is simple in structure, and result of use is good, can be widely used in various anodic oxidation fixtures.
