DETAILED DESCRIPTION

[0032] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] See also Figure 1 - Figure 6 , the present application provides a magnesium alloy micro-arc oxidation production line, comprising:

[0035] A primary electrolyte tank 100, a horizontal rail 300 is arranged on the top of the primary electrolyte tank 100, and a secondary electrolyte tank 600, a tertiary electrolyte tank 700 and a quaternary electrolyte tank 800 are arranged in sequence on the right side of the primary electrolyte tank 100;

[0036] A stand 500 is slidably mounted on the horizontal rail 300, and an electric slide 502 is slidably mounted on the horizontal rail 300 at the lower end of the stand 500. The electric slide 502 is a prior art in which a motor, a guide wheel, and a transmission belt cooperate. The stand 500 includes an internally slidably mounted lifting frame 503, and a guide wheel 504 is disposed at the end of the lifting frame 503 to slide with the inner side of the stand 500. At the same time, a lifting motor 501 is disposed on the upper end surface of the U-shaped stand 500, and a cable for lifting the lifting frame 503 can be disposed on the winding wheel disposed at the end of the lifting motor 501.

[0037] A magnesium alloy clamping mechanism 400 is installed on a lifting horizontal frame 503 to clamp and oxidize magnesium alloy products. The magnesium alloy clamping mechanism 400 can be used to clamp and fix multiple porous magnesium alloy products at the same time, so that the porous magnesium alloy products can be inserted into the electrolyte box for micro-arc oxidation processing at the same time. During the oxidation, the magnesium alloy products are alternately clamped, so that the surface of the magnesium alloy product will not be blocked all the time and can be fully oxidized, thereby improving the surface oxidation processing quality of the magnesium alloy product. The magnesium alloy clamping mechanism 400 includes a clamping member 401 installed on the lifting horizontal frame 503, a mounting plate 402 installed on the lower surface of the clamping member 401, a plurality of product clamping members 404 installed on the side of the mounting plate 402 to clamp the magnesium alloy product, and a plurality of product clamping members 404 are driven to clamp the magnesium alloy product at the same time. The lifting drive component 403 for working clamping and the transfer clamping component 405 for transferring and clamping the magnesium alloy product, the structure of the transfer clamping component 405 is the same as the lifting drive component 403 and the product clamping component 404, the difference is that a moving cylinder 406 is arranged on the upper surface of the lifting cross frame 503, and the piston rod inside the moving cylinder 406 can drive the transfer clamping component 405 to move, so as to facilitate the transfer clamping component 405 to approach the product clamping component 404, and another difference is that the support rod 4046 in the transfer clamping component 405 does not overlap with the support rod 4046 on the product clamping component 404, so as to facilitate extending into other holes of the porous magnesium alloy product, and the support rod 4046 can be set to be detachable, which is convenient for replacement and adapting to the holes on the magnesium alloy product.

[0038] In this embodiment, preferably, the product clamping member 404 includes a fixed column 4041 fixed on the inner side of the mounting plate 402. The product clamping member 404 can be used to clamp two porous magnesium alloy products at the same time, and multiple product clamping members 404 can increase the number of magnesium alloy products clamped and improve the oxidation processing efficiency of magnesium alloy products. Two sleeves 4042 are sleeved on the fixed column 4041, and the sleeves 4042 are rotatably sleeved on the fixed column 4041. A gear 4043 is sleeved on the sleeve 4042. An inner rotating plate 4045 and an outer rotating plate 4044 are respectively sleeved on the two sleeves 4042. The two rotating plates rotate at the same time, and the distance between the ends of the two rotating plates can be expanded or reduced at the same time. The inner rotating plate 4045 and the outer rotating plate 4044 are staggered inside and outside, and the inner sides of the upper ends of the two are provided with support rods 4046 for supporting the porous magnesium alloy products, and the magnesium alloy products can be sleeved on the support rods 4046.

[0039] In this embodiment, preferably, a clamping plate 4047 for clamping the magnesium alloy product mounted on the support rod 4046 is provided on the inner side of the lower end of the outer rotating plate 4044 and the inner rotating plate 4045, and since the outer rotating plate 4044 and the inner rotating plate 4045 are staggered, the shapes of the support rods 4046 supporting the magnesium alloy product on the two rotating plates are slightly different, which facilitates the alignment of the two magnesium alloy products. Similarly, the clamping plate 4047 provided at the lower ends of the two rotating plates is located below the magnesium alloy product, and an extension plate is provided on the surface of one of the rotating plates, on which the clamping plate 4047 is provided, so as to reduce the restriction on the staggered distance between the two rotating plates and facilitate the clamping and fixing of the magnesium alloy product. The clamping plate 4047 is L-shaped, and the clamping plate 4047 can approach the surface of the magnesium alloy product as the rotating plate rotates, and cooperate with the support rod 4046 to clamp and fix the magnesium alloy product.

[0040] In this embodiment, preferably, the lifting drive component 403 includes a lifting cylinder 4031 vertically installed on the inner side of the clamping component 401. The lifting drive component 403 can be used to allow the rotating plates in multiple product clamping components 404 to rotate relative to each other at the same time, and can clamp and fix multiple magnesium alloy products at the same time, reducing the trouble of manual clamping and saving the clamping time of magnesium alloy products. A fixed plate 4032 is provided at the lower end of the piston rod inside the lifting cylinder 4031, and two vertical plates 4033 respectively located on the outside of two gears 4043 are provided on the lower surface of the fixed plate 4032. The vertical plates 4033 and the rack 4034 do not affect the rotation of the rotating plate. A rack 4034 is provided on the surface of the vertical plate 4033 at a position corresponding to the gear 4043, and the length of the rack 4034 can be set as needed.

[0041] In summary, the lifting cross frame 503 is located at a higher position, the cable is in a storage state, the entire magnesium alloy clamping mechanism 400 is installed on the lifting cross frame 503 by using the clamping member 401, and a sufficient distance is left between the transfer clamping member 405 and the product clamping member 404, so that multiple magnesium alloy products can be sleeved on the support rod 4046, and the lifting cylinder 4031 works, and the piston rod inside the lifting cylinder 4031 extends, driving the fixed plate 4032 and the two vertical plates 4033 to move downward, and the two racks 4034 move downward to mesh with the two gears 4043 respectively, and the two gears 4043 rotate back and forth, driving the sleeve 4042 to rotate back and forth, and the two sleeves The inner rotating plate 4045 and the outer rotating plate 4044 on 4042 rotate relative to each other, and the distance between the ends of the two rotating plates gradually decreases. The pressing plate 4047 approaches the magnesium alloy product until it contacts the magnesium alloy product, and the magnesium alloy product is pressed and fixed. After the magnesium alloy product is fixed, the pulling motor 501 works to drive the winding wheel to rotate to gradually unfold the cable. When the cable is unfolded, the lifting cross frame 503 moves under the action of gravity, driving the entire magnesium alloy clamping mechanism 400 to move downward until all the clamped magnesium alloy products are immersed in the electrolyte in the primary electrolyte tank 100 for oxidation processing. During the oxidation processing of the magnesium alloy product, the moving cylinder 406 will work. The piston rod inside the transfer clamping member 405 is retracted, and the transfer clamping member 405 is moved to the left and close to the product clamping member 404, until the support rod 4046 in the transfer clamping member 405 extends into the other holes of the magnesium alloy product. At the same time, the two rotating plates in the transfer clamping member 405 rotate relative to each other to clamp and fix the other surfaces of the magnesium alloy product, and the two rotating plates on the product clamping member 404 rotate back and forth to separate the magnesium alloy product. The moving cylinder 406 works and the piston rod inside it extends, driving the transfer clamping member 405 and the magnesium alloy product to move to the right, and the magnesium alloy product is separated from the product clamping member 404, and the part of the magnesium alloy that was previously blocked by the clamping is exposed. , and oxidize in the electrolyte. By alternately clamping the magnesium alloy product in this way, the magnesium alloy product will not always have obstructed parts, and the surface of the magnesium alloy product can be fully oxidized, thereby improving the surface oxidation quality and oxidation efficiency of the magnesium alloy product. After the magnesium alloy product is primarily oxidized in the primary electrolyte tank 100, the stand 500 can be driven by the electric slide 502 to move backward along the horizontal rail 300 to be oxidized in the secondary electrolyte tank 600, the tertiary electrolyte tank 700 and the quaternary electrolyte tank 800 in turn. The magnesium alloy product that has been oxidized is then guided for unloading by the unloading component 900, and the unloaded magnesium alloy product enters the next process for drying.

[0045] In summary, the horizontal base plate 40471 is fixed to the surface of the rotating plate by the countersunk bolts 40473. According to the shape of the clamped magnesium alloy product, the vertical clamping plate 40472 can be rotated around the rotating shaft 40474 to change the angle between the vertical clamping plate 40472 and the horizontal base plate 40471. When the angle is appropriate, the screw ring 40475 is tightened to make it contact with the vertical clamping plate 40472, and the friction resistance is used to fix the position of the vertical clamping plate 40472, so that the vertical clamping plate 40472 and the horizontal base plate 40471 are at a suitable angle for pressing and fixing the magnesium alloy product, thereby increasing the convenience of pressing and clamping the magnesium alloy product.

The feeding member 900 includes a first-level guide filter plate 902 inclined below the cross rail 300, and a plurality of filter holes are evenly opened on the surface of the first-level guide filter plate 902, so that when the magnesium alloy product is fed along the first-level guide filter plate 902, the electrolyte on the surface The liquid drips downward into the collection box 901 through the filter holes, and a secondary adsorption plate 903 is arranged below the right end of the first-level guide filter plate 902. The secondary adsorption plate 903 is provided with a hollow rectangular adsorption structure with openings on both sides to increase the adsorption area of ​​the electrolyte on the surface of the magnesium alloy product. A collection box 901 is arranged below the first-level guide filter plate 902, and an adsorption layer 904 is arranged on the inner wall of the secondary adsorption plate 903.

At this time, the piston rod inside the push cylinder 905 retracts, driving the connecting plate 906 to move to the right, driving the push plate 907 and the push rod 908 to move to the right, and the end of the push rod 908 abuts against the magnesium alloy product, and as it moves, the magnesium alloy product is separated from the support rod 4046 and separated from the support.
