Description

Technical Field

[0001] The invention relates to the technical field of anodizing, in particular to an anodizing process for a piston. Background Art

[0002] With the development of engine technology, the requirements for pistons are getting higher and higher, especially the top of the piston. As part of the combustion chamber, the top of the piston must withstand high temperature and high pressure. The working conditions are the worst in the engine. From the faulty parts of diesel engine pistons, many piston tops are cracked, which seriously affects the engine performance. For this reason, modern engines must enhance the strength of the top of the piston, otherwise the life of the piston will be very short. At present, the most effective way to strengthen the top of the piston in the field of pistons is to anodic oxidation of the top of the piston.

[0003] Publication No. CN107313095A discloses an anodizing device and an anodizing process for a piston. However, in the existing anodizing process for a piston, before anodizing, the piston needs to be fixed on a hanger and cleaned using a cleaning device. After cleaning, the hanger is directly hung on the anode rod, and the piston is immersed in an oxidation tank for anodizing. This method easily causes a large amount of water stains remaining after cleaning to enter the electrolyte in the oxidation tank. At the same time, the piston is in a stationary state in the oxidation tank, and impurities are easily present between the hook of the hanger and the anode rod, resulting in loose contact, which affects the efficiency and effect of oxidation. After oxidation, when the piston is taken out of the oxidation tank, electrolyte is easily left on the piston and the hanger, resulting in waste of electrolyte. Summary of the invention

[0004] The present invention aims at the technical problems existing in the prior art and provides a piston anodizing process to solve the problems of the prior art piston anodizing process. When the piston is in use, it is necessary to fix it on a hanger before anodizing and use a cleaning device to clean it. After cleaning, the hanger is directly hung on the anode rod and the piston is immersed in an oxidation tank for anodizing. This method easily causes a large amount of water stains remaining after cleaning to enter the electrolyte in the oxidation tank. At the same time, the piston is in a stationary state in the oxidation tank, and impurities are easily present between the hook of the hanger and the anode rod, resulting in loose contact, which affects the efficiency and effect of oxidation. After oxidation, when the piston is taken out of the oxidation tank, electrolyte is easily left on the piston and the hanger, resulting in a waste of electrolyte.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A piston anodizing process comprises the following steps:

[0006] S1: Cleaning the piston using a cleaning device;

[0007] S2: performing an anodizing operation on the cleaned piston using an anodizing device;

[0008] The anodizing device comprises an oxidation tank, an anode rod and a hanger, and a cathode plate is arranged in the oxidation tank, the hanger comprises a connecting rod and a hook, and the hook is hung on the anode rod, the top of the oxidation tank is fixedly sleeved with an annular plate, and the top of the annular plate is connected to a first movable plate through a lifting mechanism, the bottom of the first movable plate is fixedly connected to two symmetrically arranged mounting blocks, and the anode rod is inserted into the side wall of the mounting block, a moving mechanism is arranged between the anode rod and the mounting block, a first pushing mechanism for pushing the hanger to swing is arranged below the mounting block, and the top of the annular plate is connected to two symmetrically arranged collecting tanks through a reset mechanism, the side wall of the oxidation tank is provided with a collecting mechanism for collecting water stains shaken off the piston surface after cleaning, and the movement of the collecting tank is driven by a second pushing mechanism.

[0009] The beneficial effects of the present invention are:

[0010] 1) By setting a first pushing mechanism, the piston is first fixed on the hanger, then the piston is placed in the cleaning device for cleaning, after the cleaning is completed, the hook of the hanger is hung on the anode rod, and the connecting rod is inserted into the L-shaped plate, then the motor is started, the rotation of the motor drives the rotation of the threaded rod, thereby driving the first movable plate to move downward along the guide rod, and driving the anode rod, the hanger and the piston to move downward through the mounting block, at the same time, the second movable plate and the pushing rod can be driven downward by the first reset assembly, when the pushing rod abuts against the side wall of the triangular block, the second movable plate can be pushed to move in the direction close to the first L-shaped block, at the same time, the reset spring is compressed, when the pushing rod passes over the triangular block, the second movable plate can be moved and reset under the action of the reset spring, so that the second movable plate can be reciprocated, and the hanger is driven to swing back and forth through the L-shaped plate, at the same time, the hook rotates on the side wall of the anode rod, so as to shake off the water stains remaining on its surface, and fall into the collection tank for cleaning. After the water stains are cleaned, when the second inclined surface of the second push plate is against the first push plate, the first push plate can slide along the second inclined surface to the side wall of the second push plate, thereby pushing the two collecting tanks to move away from each other. At the same time, the second spring is compressed. At this time, the top of the oxidation tank is opened. At this time, the hanger and the piston can enter the oxidation tank for anodizing, and at this time, the hanger can also be swung, thereby improving the efficiency and effect of oxidation. After the oxidation is completed, the hanger and the piston are lifted from the oxidation tank by the lifting mechanism. At this time, the hanger and the piston can also be swung, so that the electrolyte on its surface can be thrown into the oxidation tank to avoid waste of electrolyte. After the first push plate is separated from the second push plate, the two collecting tanks can move closer to each other and fit together under the action of the second spring, thereby sealing the top of the oxidation tank to prevent impurities from falling into the interior.

[0011] 2) By setting a moving mechanism, when the second moving plate moves back and forth, the pushing block can be driven to move back and forth through the connecting frame. When the pushing block moves in the direction close to the first L-shaped block, the first inclined surface abuts against the side wall of the second fixed ring, thereby pushing the second fixed ring to move in the direction close to the second L-shaped block. At the same time, the first spring is compressed and drives the anode rod to move synchronously. When the pushing block moves and resets in the direction away from the first L-shaped block, the second fixed ring can move and reset under the action of the first spring, and drive the anode rod to move and reset. In this way, the anode rod can reciprocate, and when the anode rod moves, the connecting rod is blocked by the L-shaped plate, and the hanger cannot move, so that the anode rod and the hook can rub back and forth to form a grinding effect, which is convenient for cleaning impurities and makes the contact effect between the hook and the anode rod better, thereby ensuring the efficiency and effect of oxidation.

DETAILED DESCRIPTION

[0041] With the development of engine technology, the requirements for pistons are getting higher and higher, especially the top of the piston. As a part of the combustion chamber, the top of the piston must withstand high temperature and high pressure. The working conditions are the worst in the engine. From the faulty parts of diesel engine pistons, many piston tops are cracked, which seriously affects the engine performance. For this reason, modern engines must enhance the strength of the top of the piston, otherwise the life of the piston will be very short. At present, the most effective way to strengthen the top of the piston in the field of pistons is to anodic oxidation of the top of the piston. Publication No. CN107313095A discloses an anodic oxidation device and a piston anodic oxidation process.

[0042] After in-depth investigation and research on the piston anodizing process, the inventor found that: when using the existing piston anodizing processing technology, the piston needs to be fixed on a hanger and cleaned using a cleaning device before anodizing. After cleaning, the hanger is directly hung on the anode rod, and the piston is immersed in an oxidation tank for anodizing. This method easily causes a large amount of water stains remaining after cleaning to enter the electrolyte in the oxidation tank. At the same time, the piston is in a stationary state in the oxidation tank, and impurities are easily present between the hook of the hanger and the anode rod, resulting in loose contact, affecting the efficiency and effect of oxidation. After oxidation, when the piston is taken out of the oxidation tank, electrolyte is easily left on the piston and the hanger, resulting in waste of electrolyte.

[0056] In this embodiment, Figure 1 As shown, the collecting mechanism includes a water collecting box 702 fixedly connected to the side wall of the oxidation tank 1, and the side wall of each collecting tank 16 is fixedly connected with a hose 701, and the lower end of the hose 701 is inserted into the water collecting box 702. The water stains thrown off the hanger 13 and the piston fall into the collecting tank 16 for collection, and the collected water stains can enter the water collecting box 702 through the hose 701.

[0057] The specific method of use of the present invention is as follows:

[0058] When in use, first, fix the piston on the hanger 13, then put the piston into the cleaning device for cleaning, after the cleaning is completed, hang the hook 1302 of the hanger 13 on the anode rod 12, and insert the connecting rod 1301 into the L-shaped plate 302, then start the motor 805, the rotation of the motor 805 drives the rotation of the threaded rod 804, thereby driving the first movable plate 14 to move downward along the guide rod 802, and driving the anode rod 12, the hanger 13 and the piston to move downward through the mounting block 15, and at the same time, the second movable plate 301 and the push rod 503 can be driven to move downward through the first reset assembly;

[0059] When the push rod 503 abuts against the side wall of the triangular block 502, the second movable plate 301 can be pushed to move in the direction close to the first L-shaped block 401. At the same time, the reset spring 403 is compressed. When the push rod 503 passes over the triangular block 502, the second movable plate 301 can be moved and reset under the action of the reset spring 403. This reciprocating motion can make the second movable plate 301 reciprocate and drive the hanger 13 to swing back and forth through the L-shaped plate 302. At the same time, the hook 1302 rotates on the side wall of the anode rod 12, so as to facilitate the removal of water stains remaining on its surface and fall into the collecting tank 16 for collection. The collected water stains can enter the water collecting box 702 through the hose 701, so as to prevent the water stains from entering the oxidation tank 1, thereby ensuring the efficiency and effect of oxidation.

[0060] After the water stains are cleaned, when the second inclined surface 1004 of the second push plate 1003 abuts against the first push plate 1002, the first push plate 1002 can slide along the second inclined surface 1004 to the side wall of the second push plate 1003, thereby pushing the two collecting tanks 16 to move away from each other. At the same time, the second spring 903 is compressed. At this time, the top of the oxidation tank 1 is opened. At this time, the hanger 13 and the piston can enter the oxidation tank 1 for anodizing. At this time, the hanger 13 can also swing, thereby improving the efficiency and effect of oxidation.

[0061] At the same time, when the second movable plate 301 reciprocates, the push block 602 can be driven to reciprocate through the connecting frame 601. When the push block 602 moves toward the direction close to the first L-shaped block 401, the first inclined surface 603 abuts against the side wall of the second fixing ring 203, thereby pushing the second fixing ring 203 to move toward the second L-shaped block 201. At the same time, the first spring 204 is compressed and drives the anode rod 12 to move synchronously. When the push block 602 moves toward the direction away from the first L-shaped block 401, the first inclined surface 603 abuts against the side wall of the second fixing ring 203. When the anode rod 12 is in the position, the second fixing ring 203 can be moved and reset under the action of the first spring 204, and drive the anode rod 12 to move and reset, and the anode rod 12 can be reciprocated in this way, and when the anode rod 12 moves, the connecting rod 1301 is blocked by the L-shaped plate 302, and the hanger 13 cannot move, so that the anode rod 12 and the hook 1302 can be reciprocated and rubbed to form a grinding effect, which is convenient for cleaning impurities, so that the contact effect between the hook 1302 and the anode rod 12 is better, thereby ensuring the efficiency and effect of oxidation;

[0062] After the oxidation is completed, the hanger 13 and the piston are lifted from the oxidation tank 1 by the lifting mechanism. At this time, the hanger 13 and the piston can also be swung so that the electrolyte on their surface can be thrown into the oxidation tank 1 to avoid waste of electrolyte. When the first push plate 1002 is separated from the second push plate 1003, the two collecting tanks 16 can move closer to each other and fit together under the action of the second spring 903, thereby sealing the top of the oxidation tank 1 to prevent impurities from falling into the inside.

[0063] In summary: the beneficial effect of the present invention is specifically reflected in that during oxidation, the hanger 13 and the piston can be swung, and the anode rod 12 and the hook 1302 can be rubbed back and forth to form a polishing effect, which is convenient for cleaning impurities and makes the contact effect between the hook 1302 and the anode rod 12 better, thereby improving the efficiency and effect of oxidation; after the oxidation is completed, the hanger 13 and the piston can also be swung, so that the electrolyte on their surface can be thrown into the oxidation tank 1 to avoid waste of electrolyte.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
