Description

Technical Field

[0001] The utility model belongs to the field of tooling fixtures for electroplating surface treatment, and specifically relates to a tooling fixture for batch local electroplating of round-head plugged parts. Background Art

[0002] There are many types of plugs and different shapes. Among them, round head plugs have dual characteristics of function and appearance and are widely used in the aerospace field. The round head plug part structure is semi-circular and shaped like a decorative cap. One end has a semi-circular smooth surface and the other end has an external thread. It can be directly used for thread assembly and has a high surface finish. Figure 1 In order to obtain high-quality surface performance (wear resistance, corrosion resistance, decorative properties, etc.), it is difficult to perform local electroplating operations on the round head surface in batches.

[0003] Electroplating production using a simple wrapping method for production auxiliary materials cannot achieve clear plating boundaries, and loose wrapping can lead to over-plating, resulting in rework and reduced production efficiency. Therefore, it is necessary to design a fixture for batch electroplating of round head plugs. The designed fixture can eliminate short circuits in parts and, when applied in actual batch production, achieve a uniform and aesthetically pleasing coating in a single pass. This reduces individual differences in part plating and reduces the consumption of production auxiliary materials, improving part electroplating efficiency. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a tooling fixture for batch local electroplating of round-headed plugging parts, including: a hook body, a main rod, a support rod and a shielding protective shell, one end of the hook body is suspended on the conductive copper rod in the slot, and the other end is connected to the upper end of the main rod. There are multiple support rods, and the multiple support rods are distributed up and down and are arranged in parallel on the lower end of the main rod. The front and rear end surfaces of the multiple support rods are respectively provided with multiple conductive blocks, and the conductive blocks on the front and rear end surfaces of the multiple support rods are cross-distributed front and back, and the ends of the conductive blocks are in contact with the parts. One end of the shielding protective shell is sleeved on the conductive block, and the other end is sleeved on the part.

[0006] Furthermore, the other end of the hook body is welded to the upper end of the main rod, and the middle parts of the rear end surfaces of the plurality of support rods are welded to the lower end of the main rod at equal intervals.

[0007] Furthermore, the spacing between the multiple support rods is 15 cm to 20 cm.

[0009] Furthermore, the hook body is a copper plate hook, and its shape is a hook structure.

[0010] Furthermore, the conductive block is a cylinder with external threads. One end of the conductive block is welded to the front and rear end faces of the support rod respectively, and the other end face is close to the part, ensuring that the conductive block has good contact with the part and has sufficient conductive cross-sectional area to provide the part with effective plating current and voltage.

[0011] Furthermore, the shielding protective shell is a cylinder with a through hole in the middle, and an internal thread is provided at one end of the through hole for assembly with the external thread of the conductive block. Tightening the shielding protective shell can position the part in the center. The shape of the through hole of the shielding protective shell is determined by the morphology and size of the part and the conductive block. One end of the shielding protective shell is connected to the external thread of the conductive block through the internal thread, and the other end is put on the part through the through hole, and the round head area of ​​the part is exposed.

[0012] Furthermore, the total length of the shielding protection shell is greater than the total length of the conductive block.

[0013] In the utility model, the copper plate hook is processed into the style of a hook, which can be directly hung on the conductive copper rod in the tank. The parts are placed on the tooling fixture of the utility model. The entire tooling fixture and the anode are parallel in the tank. During the plating process, the utility model working fixture is parallel to the anode, so that the clamped parts will face the round head surface area to be electroplated towards the anode plate.

[0014] In the present invention, the part is a round-head plugging part.

[0015] The beneficial effects of this utility model are as follows: it can be applied to batch production of local electroplating with rounded head plugging, avoiding surface defects in the coating caused by traditional mounting methods, directly eliminating short circuits in parts, and achieving a uniform coating with a qualified appearance through a single coating. After use, it reduces individual differences in part plating, reduces the consumption of production auxiliary materials, improves part electroplating production efficiency, ensures that parts are delivered on time, and significantly saves production costs.

[0028] like Figures 1 to 7 As shown, the utility model provides a fixture for batch local electroplating of round-head plugging parts, including a copper plate hook 1, a main rod 2, a support rod 3, a conductive block 3-1, a shielding protective shell 4 and a part 5;

[0029] The copper plate hook 1, main rod 2 and support rod 3 are welded together. The other end of the copper plate hook 1 is welded to the upper end of the main rod 2, and the middle of the rear end face of the support rod 3 is welded to the lower end of the main rod 2. The main rod 2 and the support rod 3 are made of brass with good conductivity and elasticity, which plays the role of conductive and supporting parts. According to the depth of the tank liquid level, two support rods 3 are welded to the lower end of the main rod 2. The spacing between the two support rods 3 is 15 cm to 20 cm, and the two support rods 3 are parallel to each other and welded to the bottom and lower end of the main rod 2 respectively.

[0030] A plurality of conductive blocks 3-1 are cross-welded on the front and rear end surfaces of the support rod 3. The conductive blocks 3-1 are made of brass. The plurality of conductive blocks 3-1 are cylindrical with external threads. Each conductive block 3-1 is connected to a shielding protective shell 4 through threads. The end surface of the other end of each conductive block 3-1 is closely attached to a part 5, ensuring that the conductive block 3-1 is in good contact with the part 5 and has sufficient conductive cross-sectional area to provide the part 5 with effective plating current and voltage.

[0031] The shielding protective shell 4 is made of insulating material polytetrafluoroethylene. The shielding protective shell 4 is a hollow cylindrical structure. One end of the hollow inner cavity is provided with an internal thread for assembly with the external thread on the conductive block 3-1. One end of the shielding protective shell 4 is connected to the external thread of the conductive block 3-1 through the internal thread, and the other end is directly sleeved on a part 5 through the inner cavity, with the round head area of ​​the part 5 exposed. Tightening the shielding protective shell 4 can position the part 5 in the center position. The shape and size of the inner cavity of the shielding protective shell 4 are determined by the shape and size of the part 5 and the conductive block 3-1.

[0032] The copper plate hook 1 is processed into a hook style, and one end of the copper plate hook 1 can be directly hung on the conductive copper rod in the tank through the hook structure. The part 5 is placed on the fixture of the utility model, and the entire fixture and the anode are parallel in the tank. During the plating process, the working fixture of the utility model is parallel to the anode, so that the clamped part 5 will face the round head surface area to be electroplated towards the anode plate.

[0033] Preferably, the length of the main rod 2 and the number of equally divided support rods 3 increase with the depth of the effective electroplating area of ​​the plating tank. Each support rod 3 is parallel to each other and welded to the lower end of the main rod 2 at equal intervals, and each support rod 3 is distributed vertically to the main rod 2.

[0034] Preferably, each conductive block 3 - 1 is vertically distributed to the front and rear end surfaces of the support rod 3 .

[0035] Preferably, the total length of the shielding protective shell 4 is greater than the total length of the conductive block 3 - 1 .

[0036] Preferably, the part 5 is a round-head plugging part.

[0037] The working principle of this utility model is as follows: Based on the external characteristics of part 5, a fixture for batch local electroplating of round-head plugged parts is designed. The designed fixture is mainly divided into a conductive hanging area and a shielding protection area. Part 5 is placed in a shielding protective shell 4, with the plating surface exposed. The bottom of part 5 is precisely attached to the conductive block 3-1. It is suspended and assembled by threads on the shielding protective shell 4 and the conductive block 3-1. It is easy to install and hang, and can be evenly arranged on both sides of the fixture. During the plating process, the designed copper plate hook 1 and the conductive copper rod have good electrical conductivity. The area of ​​contact between part 5 and the conductive block 3-1 is large, and the current is evenly dispersed, reducing energy loss and improving production efficiency.

[0038] This new fixture is used for batch electroplating of blocked parts, improving traditional electroplating methods and avoiding surface defects in the coating caused by traditional mounting methods. It directly prevents short circuits in parts and achieves uniform, aesthetically pleasing coatings in a single pass. This reduces individual variations in part plating quality while also reducing the consumption of auxiliary materials, improving part electroplating production efficiency, ensuring on-time delivery of parts, and significantly saving production costs.

[0039] The above description of the inventive design principles and performance advantages of this clamp is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of this utility model and present preferred embodiments. Modifications or equivalent substitutions of the new technical solution may be made without departing from the scope of the technical solution of this utility model and shall be covered by the scope of the claims of this utility model.
