Description

Technical Field

[0001] This invention relates to the field of electroplating technology, specifically to an electroplating protection fixture and method for an oil inlet pipe nozzle. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation (such as rust), improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. Many coins also have an electroplated outer layer.

[0003] Electroplating requires electroplating protection fixtures for oil inlet connectors. For example, Chinese Patent discloses an electroplating protection fixture for an oil inlet connector (Publication No.: CN214300403U), which includes a plug cap and a plug head. The end face of the plug head is provided with a central shaft for connecting the oil inlet connector along the horizontal axis direction. The other end of the central shaft is provided with an external thread. The end face of the plug cap opposite to the plug head is provided with a circular hole. The circular hole is provided with an internal thread that matches the external thread. After the plug head and plug cap are connected to the oil inlet connector, the end face of the oil inlet connector is located inside the end face of the plug head or plug cap. The tooling of this invention is convenient and flexible to adjust and easy to operate, improving the protection of workpieces and the efficiency of electroplating. The above-mentioned patent is convenient and flexible to adjust and easy to operate. However, it cannot completely seal the inside of the oil inlet connector during use, which makes the plug of the oil inlet connector easy to loosen during use. When electroplating the surface of the oil inlet connector, the inside is also easy to be electroplated. It cannot stably seal the inside of the oil inlet connector, thus affecting the normal use by the user. Summary of the Invention

[0048] refer to Figures 2 to 6 This includes the following steps:

[0049] S1: The user inserts the fixing rod 45 into the inside of the oil inlet connector 1 from the bottom through the connector 44, and then inserts the connecting sleeve 42 into the inside of the oil inlet connector 1 from the top through the hand dial 41. Then, the user rotates the hand dial 41 to drive the connecting sleeve 42 to rotate, so that the screw 46 is inserted into the inside of the connecting sleeve 42, so that the connecting sleeve 42 is connected to the fixing rod 45. The connecting sleeve 42 fixes the top sealing sleeve 43, and the top sealing sleeve 43 seals the inside of the oil inlet connector 1. Then, the user fixes the bottom sealing sleeve 47 through the fixing rod 45, and the bottom sealing sleeve 47 seals the inside of the oil inlet connector 1. Then, S2 is executed.

[0050] S2: The user inserts the connecting plate 31 into the limiting groove 7, then places the limiting plate 51 at the bottom of the connector 44, so that the limiting bolt 52 is inserted into the connecting plate 31 to fix the connecting plate 31. The connecting plate 31 fixes the connecting block 32. Then, the user pushes the positioning plate 33 to rotate upward so that the through hole 34 is fitted inside the connecting bolt 22. Then, the nut 23 is threaded onto the surface of the connecting bolt 22 to fix the positioning plate 33. The fixing plate 21 fixes the connector 44 a second time through the limiting mechanism 5 to prevent the connecting sleeve 42 and the connector 44 from shaking and creating gaps, allowing the electroplating solution to enter from the top and bottom of the oil inlet nozzle 1 into the interior of the oil inlet nozzle 1, thereby preventing the interior of the oil inlet nozzle 1 from being electroplated.

[0051] The working principle and usage process of this invention are as follows: In use, the user inserts the fixing rod 45 into the oil inlet connector 1 from the bottom using connector 44, then inserts the connecting sleeve 42 into the oil inlet connector 1 from the top using hand dial 41. Rotating hand dial 41 causes the connecting sleeve 42 to rotate, allowing the screw 46 to insert into the connecting sleeve 42, connecting the connecting sleeve 42 to the fixing rod 45. The connecting sleeve 42 fixes the top sealing sleeve 43, sealing the top of the inside of the oil inlet connector 1. The fixing rod 45 then fixes the bottom sealing sleeve 47, sealing the bottom of the inside of the oil inlet connector 1. Then... The user inserts the connecting plate 31 into the limiting groove 7, then places the limiting plate 51 at the bottom of the connector 44, so that the limiting bolt 52 is inserted into the connecting plate 31 to fix the connecting plate 31. The connecting plate 31 fixes the connecting block 32. Then, the user pushes the positioning plate 33 to rotate upward so that the through hole 34 fits inside the connecting bolt 22. Then, the nut 23 is threaded onto the surface of the connecting bolt 22 to fix the positioning plate 33.

[0052] In summary, this electroplating protection fixture and method for the oil inlet connector 1, by setting a fixing mechanism 4, can seal the top and bottom of the inside of the oil inlet connector 1. Then, by increasing the area of ​​the hand dial 41 through the top protection mechanism 2, the top of the oil inlet connector 1 is sealed. Then, the fixing plate 21 and connector 44 are fixed again to prevent the fixing plate 21 and connector 44 from shaking and creating gaps. When the user uses it, the plug of the oil inlet connector 1 will not loosen. When the surface of the oil inlet connector 1 is electroplated, the inside will not be electroplated. It can stably seal the inside of the oil inlet connector 1, thereby ensuring normal use by the user.
