Abstract
The invention relates to a clamping method and a clamping device for anodizing of a complex part. Supporting frames of the clamping device are metal frames taking the shape of an inverted triangle; metal hooks, which can be connected with electrodes, are arranged at the tops of the supporting frames; a rotating shaft, which can rotate, is horizontally connected with the lower end of the supporting frames; and one end of the rotating shaft is connected with a motor through a belt pulley. The clamping method comprises the following steps: a part to be anodized is fixed on a part locating pin, and is then immersed into an anodizing bath solution; and the motor is started to enable the part to rotate around the rotating shaft at the angular velocity of 12 to 15 degrees per second in the bath solution.
Description
Technical field
The application relates to aircraft manufacturing technical field, in the anodizing production process particularly for aircraft complex profile part, specifically a kind of to the anodized clamp method of complicated shape and clamping fixture.
Background technology
Metal anode metallization processes plays an important role in industry manufacture.Anodizing rete has feature that is corrosion-resistant, wear-resisting, surface aesthetic, and different anodizing retes all has specific function.Metal anodised mechanism is under the effect of electric current, makes metallic surface generate specific oxidation film layer.
In the process of oxidizing reaction, electric current flows between liquid and metal, makes solution and metal exchange ion, generates oxide film.This reaction generates hydrogen and other salt compounds, and hydrogen leaves conversion zone after rising to liquid level, and salt compounds is dissolved in solution.If metallic surface can contact fresh solution, anodizing just can continue to carry out, and anodizing rete continues to thicken.After anodizing rete reaches specific thicknesses, part departs from tank liquor, terminates anodizing operations.And to Complex Surface Part, due to the stacked covering of design of part, gas can not be discharged by parts locally surface smoothly, wrapping on part because forming hydrogen between solution and part, forming anodizing blocking layer.After part extracts from solution tank, show as blackout, striated impression.
Summary of the invention
The object of the present invention is to provide the anodized clamp method of a kind of complicated shape and clamping fixture.
The anodized clamp method of a kind of complicated shape, it is characterized in that: 1) have a clamping device, the bracing frame of this clamping device is the metal frame of a del, be provided with at the top of bracing frame can with the metal hanger of Electrode connection, a rotary rotation axis is had at the lower end level connection joint of bracing frame, a termination of rotation axis is connected with motor by belt pulley, and motor is fixed on the top of bracing frame, is provided with part steady brace on the rotating shaft; 2) will be fixed on above-mentioned part steady brace by anodized part, then immerse in anodizing tank liquor; 3) starter motor makes part rotate with the circular frequency of 12 degree to the 15 degree p.s. moving axis that rotates in tank liquor.
The invention has the beneficial effects as follows: drive part to rotate in tank liquor by belt pulley, make each surface of part in succession in solution inside upward.In this process, the bubble that anodizing produces just can emersion liquid level, and metal parts surface contact fresh solution, eliminates drawback part complex profile wrapping bubble, and anodic film layer thickness uniformity, meets Production requirement.
Below in conjunction with embodiment, the application is described in further detail.
Accompanying drawing explanation
Fig. 1 is the anodized aircraft end rib design of part signals of a kind of needs
Fig. 2 is the structural representation of a kind of anodizing clamping fixture
Fig. 3 is the signal of a kind of aircraft end rib part anode clamp method
Number description: 1 part, 2 motors, 3 hooks, 4 bracing frames, 5 belt pulleys, 6 rotation axiss, 7 steady braces
Embodiment
See accompanying drawing, embodiment provides carries out anodized clamping to end rib part typical on aircraft, and slot in this part 1 two sides, parallel to each other.In anodized process, owing to not accomplishing complete level, general status is that in a groove, air can be overflowed, and the bubble in an other groove is arranged not out.Result fails to get rid of the groove inner accumulated gas of bubble, produces the defect of blackout, impression.
Fig. 2 is the anodizing clamping device schematic diagram that the application proposes, the bracing frame 4 of this clamping device is the metal frame of a del, be provided with at the top of bracing frame 4 can with the metal hanger 3 of Electrode connection, in order to stable, this metal hanger has four, be located at the position at four angles of bracing frame respectively, in the lower end of bracing frame 4, level connection joint has a rotary rotation axis 6, a termination of rotation axis 6 is connected with motor 2 by belt pulley 5, motor 2 is fixed on the top of bracing frame 4, and rotation axis 6 is provided with part steady brace 7.
During anodizing, will be fixed on the steady brace 7 of clamping device rotation axis 6 by its pilot hole by anodized part 1, as shown in Figure 3, then four metal hanger 3 dresses are hung on electrode bar, again part and clamping device are immersed in anodizing tank liquor, note the part that liquid level answers submergence to rotate, keep the part moment to be under liquid level, liquid level can not contact motor installation panel simultaneously, avoids tank liquor to corrode panel and motor.Starter motor 2, drives rotation axis 6 and part 1 fixed thereon to rotate by belt pulley 5, and part 1 is rotated with the circular frequency of 12 degree to the 15 degree p.s. moving axis 6 that rotates in tank liquor.Rotation axis 6 drives part to rotate with CAV, and all surface gas of part can be discharged very soon, and part can continue anodizing, thus avoids blackout, the impression defect of metallic surface.
