[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figures 1 to 3 As shown, a sealing treatment device for alloy micro-arc oxidation film comprises: a bracket 1, an inner support hanger 2, a sealing pool 3, and an oven 4; the oven 4 is close to one side of the sealing pool 3, the bracket 1 is arranged across the sealing pool 3 and the oven 4, a lead screw 10 is passed through the bracket 1, a first motor 11 is fixedly installed on the outer side of the side plate of the bracket 1, one end of the lead screw 10 passes through the side plate of the bracket 1 and is fixedly connected to the output end of the first motor 11, a nut 12 is screwed on the lead screw 10, a telescopic cylinder 13 is fixedly installed at the lower end of the nut 12, and the inner support hanger 2 is fixedly installed at the telescopic end of the telescopic cylinder 13;

[0019] The oven 4 includes an outer box 40, an inner box 41, a heating wire 42, thermal insulation cotton 43, and a cover plate 44. The inner box 41 is placed inside the outer box 40, the heating wire 42 is arranged inside the inner box 41, and thermal insulation cotton 43 is arranged between the inner box 41 and the outer box 40. The cover plate 44 is erected above the inner box 41, and a push rod 46 is fixedly installed above the cover plate 44 on one side close to the sealing pool 3.

[0020] Specifically, the first motor 11 rotates, driving the lead screw 10 to rotate, causing the nut 12 on the lead screw 10 to perform translational motion, driving the inner support hanger 2 and the installed alloy cylinder to perform horizontal movement; the telescopic cylinder 13 drives the inner support hanger 2 and the installed alloy cylinder to perform vertical movement; the sealing pool 3 is filled with a sealant, and the alloy cylinder after micro-arc oxidation is immersed in the sealant for sealing; a cover plate 44 is provided on the inner box 40, and a thermal insulation cotton 43 is provided between the inner box 40 and the outer box 41 to prevent heat loss.

[0021] It also includes: a rebound box body 5, which is fixedly installed on the outer wall of the outer box 40, and the end of the cover plate 44 away from the sealing pool 3 passes through the side wall of the outer box 40 and is arranged in the rebound box body 5. A sliding groove 45 is opened on the cover plate 44, and a spring 50 and a limiting connecting rod 51 are arranged in the rebound box body 5. One end of the spring 50 is fixedly connected to the side of the cover plate 44, and the other end is fixedly connected to the inner wall of the rebound box body 5. One end of the limiting connecting rod 51 is hinged to the rebound box body 5, and the bottom of the other end is clamped in the sliding groove 45.

[0022] Specifically, when the internal support sling 2 translates towards the oven 4, it pushes the push rod 46 to open the cover plate 44. The cover plate 44 squeezes the spring 50, causing the limit link 51 to move along the sliding groove 45. When the internal support sling 2 moves away from the oven 4, the spring 50 releases its elastic potential energy and pushes the cover plate 44 back to its original position.

[0023] The internal support sling 2 includes: a mounting frame 20, a second motor 21, a screw rod 22, a nut 23, a central shaft rod 24, a bushing 25, and a support assembly. The second motor 21 is fixedly installed on the mounting frame 20. The top of the screw rod 22 passes through the bottom plate of the mounting frame 20 and is fixedly connected to the output end of the second motor 21. The screw rod 22 is rotationally connected to the central shaft rod 24. A nut 23 is screwed onto the screw rod 22. A bushing 25 is fixedly connected to the central shaft rod 24. Four groups of support assemblies are evenly arranged around the screw rod 22 and the central shaft rod 24.

The lower end of the second connecting rod 27 is hinged to the bushing 25, and the upper end is hinged to the top of the support block 28. The middle parts of the first connecting rod 26 and the second connecting rod 27 are hinged together in an X shape.

[0024] Specifically, place the alloy cylinder outside the internal support sling 2, turn on the second motor 21. The second motor 21 drives the screw rod 22 to rotate, and the nut 23 moves downward. The distance between the nut 23 and the bushing 25 decreases, and the first connecting rod 26 and the second connecting rod 27 push the support block 28 outwards to fix the alloy cylinder. After the sealing treatment is completed, reverse the second motor 21, the nut 23 moves upward, the distance between the nut 23 and the bushing 25 increases, and the first connecting rod 26 and the second connecting rod 27 pull the support block 28 inwards, and then the alloy cylinder can be removed.

[0025] A mounting plate 47 is fixed on the inner wall of the outer box 40. A strip-shaped groove is formed on the mounting plate 47. A limit block 48 is fixedly arranged at one end of the cover plate 44 close to the mounting plate 47. The limit block 48 is adapted to the shape of the strip-shaped groove.

[0026] A PH electrode probe 30 is provided in the sealing hole pool 3. Testing the PH of the sealing agent in the sealing hole pool facilitates the adjustment of the sealing agent.

The first motor 11 is turned on, and the alloy cylinder is moved above the sealing hole pool 3. The telescopic cylinder 13 extends to immerse the alloy cylinder into the sealing agent in the sealing hole pool. After soaking for 5 to 10 minutes, the telescopic cylinder 13 shortens to lift the alloy cylinder. The first motor 11 is turned on again, and the alloy cylinder is moved above the oven 4. The mounting frame 20 pushes the push rod 46 to open the cover plate 44. The telescopic cylinder 13 extends to place the alloy cylinder into the inner box 41 of the oven 4. The heating wire 42 is energized to heat to 120 to 150 °C, and after curing for 15 to 20 minutes, the sealing treatment of the micro-arc oxidation film is carried out. The telescopic cylinder 13 shortens to lift the alloy cylinder. The first motor 11 is reversed. After the internal support lifting tool 2 is moved away, the cover plate 44 is automatically closed by the driving of the elastic return component, and the heat inside the oven 4 is retained.

[0028] The present utility model has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner.
