Description

Technical Field

[0001] This utility model relates to the technical field of anode racks for electroplating, and in particular to an anode rack for zinc-nickel electroplating. Background Technology

[0002] In modern manufacturing processes, especially in the electronics manufacturing industry, anodizing is one of the most commonly used metal surface treatment methods. It uses chemical or electrochemical treatment to cause the metal material, which serves as the anode, to form a film layer containing the metal components on its surface by applying an external current in a specific electrolyte. Through anodizing, the surface of the metal material can be endowed with a beautiful appearance, good corrosion resistance, wear resistance, insulation and other functions, thereby meeting different design requirements.

[0003] When performing anodizing of workpieces, the workpiece to be treated must first be fixed on a hanger. After fixing, the hanger is suspended from the conductive rod of the anodizing tank for subsequent processing. Chinese utility model patent CN205329195U discloses a cylindrical anodizing hanger, including a support column, an upper bracket, a lower bracket, and a fixing mechanism. The support column is a metal support column; the upper bracket is circular in the center and extends radially outwards along the center to form a metal support; the lower bracket is an insulating support with the same shape as the upper bracket; the support column passes through the upper bracket and is connected to the lower bracket at one end; the upper and lower brackets are also equipped with a fixing mechanism located at the radial ends of the upper and lower brackets. The hanger described in this utility model is a special hanger for cylindrical anodizing. It has a reasonable structure, a large circular hanger area, high space utilization, and a large load capacity, allowing for the anodizing of multiple products at once.

[0004] However, the above-mentioned fixture is fixedly connected to the support column by a single tightening nut. This connection is a point contact. When there are many heavy workpieces, the bolts may loosen, causing the metal support to shake, resulting in uneven electroplating. In severe cases, it may even cause the metal support to detach from the support column, resulting in low electroplating efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an anode fixture for zinc-nickel electroplating, which solves the above-mentioned technical problems, provides a stable and secure connection between the support column and the upper disc, ensures the safety of the electroplating process, improves electroplating efficiency, and facilitates the installation of the workpiece to be electroplated.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anode hanger for zinc-nickel electroplating, including a fixing mechanism and a support column. The support column is provided with an upper disk and a lower disk. The outer circumference of the upper disk and the lower disk are respectively provided with a metal bracket and an insulating bracket that extend radially outward. An adjusting component is provided in the middle of the upper disk. The adjusting component includes a sliding block. The sliding block is welded above the center of the upper disk. The support column slides through the sliding block. A moving rod is slidably provided and a fixed rod is fixedly provided inside the sliding block. The moving rod and the fixed rod are provided with an arc-shaped groove on the side wall near the support column. When the moving rod and the fixed rod abut against each other, the arc-shaped groove is tightly attached to the outer wall of the support column to clamp the support column. A stud is fixedly connected to the moving rod. The end of the stud that passes through the fixed column and passes through the sliding block is threadedly connected to an operating wheel. The operating wheel rotates and connects to the sliding block.

[0007] By adopting the above technical solution, the upper disc is slidably connected to the support column via a sliding block. When the operating wheel is rotated, the moving rod is slidably connected within the sliding block, so the moving rod and stud only rise and fall under the drive of the operating wheel, without rotating. When the operating wheel is rotated clockwise, the stud moves away from the fixed rod, thereby moving the moving rod away from the fixed rod, causing the arc-shaped groove on the fixed rod to disengage from the support column, releasing the restriction on the support column. At this time, the distance between the upper and lower discs can be adjusted according to the size of the workpiece to be electroplated to adapt to different workpiece requirements, with wide adaptability. After adjustment, the operating wheel is rotated counterclockwise, causing the stud and moving rod to move closer to the fixed rod until the fixed rod and moving rod just abut against each other. At this time, the two arc-shaped grooves form a semi-circular groove that is tightly attached to the outer wall of the support column, and the support column is confined within the arc-shaped groove, ensuring a stable connection between the upper disc and the support column, effectively preventing shaking and detachment, and improving the safety and efficiency of subsequent electroplating.

[0008] A further feature of this invention is that the bottom of the support column is detachably connected to a base, the base comprising two vertically welded base plates, the two base plates being arranged in a cross shape and having a fixing pipe at their overlapping point, and the support column being threadedly connected to the fixing pipe.

[0009] By adopting the above technical solution, when a support column is needed to support the workpiece on the workbench for easy installation, the support column only needs to be threaded into the fixed tube, so that the support column is stably supported on the cross-shaped connection base plate, thus achieving the support of the support column and facilitating the loading of the workpiece.

[0010] A further feature of this invention is that a crossbar is welded to the top of the support column, and a hook is welded to the crossbar.

[0011] By adopting the above technical solution and setting up hooks, it is convenient to suspend the fixture on the conductive rod of the anodizing tank for subsequent processing, thereby improving electroplating efficiency.

[0012] A further feature of this invention is that the sliding block has a groove, and the moving rod is slidably connected in the groove.

[0013] By adopting the above technical solution, a sliding connection between the moving rod and the sliding block is achieved, so that the moving rod can only move up and down within the sliding block without rotating.

[0014] A further feature of this invention is that the outer circumference of the operating wheel is provided with anti-slip texture.

[0015] By adopting the above technical solution and setting anti-slip texture, it is ensured that the hand will not slip when the operating wheel is rotating, thus improving the safety of operation.

[0016] A further feature of this invention is that a limiting block is fixed at one end of the stud near the operating wheel, the limiting block being used to prevent the stud from detaching from the operating wheel.

[0017] By adopting the above technical solution, a limiting block is welded to the end of the stud near the operating wheel to prevent the stud from detaching from the operating wheel.

[0018] A further feature of this invention is that the support column, the upper disc, and the metal bracket are made of titanium-aluminum alloy.

[0019] A further feature of this invention is that it includes a fixing mechanism located at the end of the metal bracket and insulating bracket away from the support column, which is used to fix the workpiece to be electroplated.

[0020] By adopting the above technical solution, a fixing mechanism is set up to fix the workpiece to be electroplated.

[0021] The beneficial effects of this utility model are as follows: In this application, the upper disc is slidably connected to the support column via a sliding block. When the operating wheel is rotated, the moving rod is slidably connected within the sliding block, so the moving rod and stud only rise and fall under the drive of the operating wheel, without rotating. When the operating wheel is rotated clockwise, the stud moves away from the fixed rod, thereby moving the moving rod away from the fixed rod, causing the arc-shaped groove on the fixed rod to disengage from the support column, releasing the restriction on the support column. At this time, the distance between the upper and lower discs can be adjusted according to the size of the workpiece to be electroplated to adapt to different workpiece requirements, thus having wide adaptability. After adjustment, the operating wheel is rotated counterclockwise, causing the stud and moving rod to move closer to the fixed rod until the fixed rod and moving rod only abut against each other. At this time, the two arc-shaped grooves form a semi-circular groove that is tightly attached to the outer wall of the support column, and the support column is confined within the arc-shaped groove, ensuring a stable connection between the upper disc and the support column, effectively preventing shaking and detachment, and improving the safety and efficiency of subsequent electroplating.

[0027] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example: An anode rack for zinc-nickel electroplating, such as... Figures 1-3As shown, the device includes a support column 1, with a crossbar 8 welded to the top of the support column 1. A hook 9 is welded to the crossbar 8. The support column 1 has an upper disc 2 and a lower disc 3. The outer circumference of the upper disc 2 has uniformly arranged metal supports 4 extending radially outward. The outer circumference of the lower disc 3 has uniformly arranged insulating supports 5 extending radially outward. An adjusting component 6 is provided in the middle of the upper disc 2. The adjusting component 6 includes a sliding block 61, which is welded above the center of the upper disc 2. The support column 1 slides through the sliding block 61. A moving rod 62 and a fixed rod 62 are slidably arranged inside the sliding block 61. The device includes a fixed rod 63 and a movable rod 62. The fixed rod 63 has an arc-shaped groove 64 on its side wall near the support column 1. When the movable rod 62 abuts against the fixed rod 63, the two arc-shaped grooves 64 form an arc-shaped concave surface that fits tightly against the outer wall of the support column 1 to clamp the support column 1. A stud 65 is fixedly connected to the movable rod 62. The stud 65 passes through the fixed column and is threaded to an operating wheel 66 at one end that passes through the sliding block 61. The operating wheel 66 is rotatably connected to the sliding block 61. The device also includes a fixing mechanism located at the end of the metal bracket 4 and the insulating bracket 5 away from the support column 1 for fixing the workpiece to be electroplated.

[0029] Its working principle is as follows: First, when the operating wheel 66 is rotated clockwise, the stud 65 is moved away from the fixed rod 63, thereby moving the moving rod 62 away from the fixed rod 63. This causes the arc-shaped groove 64 on the fixed rod 63 to disengage from the support column 1, releasing the restriction on the support column 1. At this time, the distance between the upper disc 2 and the lower disc 3 can be adjusted according to the size of the workpiece to be electroplated to adapt to different workpiece requirements. After adjustment, the operating wheel 66 is rotated counterclockwise, causing the stud 65 and the moving rod 62 to move closer to the fixed rod 63 until the fixed rod 63 and the moving rod 62 are tightly abutted. At this time, the two arc-shaped grooves 64 form a semi-circular groove that is tightly attached to the outer wall of the support column 1. The support column 1 is tightly restricted and fixed in the arc-shaped groove 64, ensuring that the upper disc 2 and the support column 1 are firmly connected, effectively preventing shaking and falling off, and improving the safety and efficiency of subsequent electroplating.

[0030] After installation, the support column 1 is securely suspended using hook 9 to ensure the stability of the workpiece during electroplating, avoid uneven electroplating caused by shaking, and improve electroplating quality.

[0031] Specifically, the bottom of the support column 1 is detachably connected to a base 7. The base 7 includes two vertically welded base plates 71. The two base plates 71 are arranged in a cross shape and a fixing tube 72 is provided at the overlapping part. The support column 1 is threadedly connected to the fixing tube 72, which facilitates the support column 1 to be supported and fixed on the workbench for the installation of the workpiece to be electroplated.

[0032] Specifically, the sliding block 61 is provided with a sliding groove, and the moving rod 62 is slidably connected in the sliding groove to realize the sliding connection between the moving rod 62 and the sliding block 61.

[0033] Specifically, the outer circumference of the operating wheel 66 is provided with anti-slip texture 661 to prevent slippage when rotating the operating wheel 66.

[0034] Specifically, a limiting block 10 is fixed at one end of the stud 65 near the operating wheel 66, and the limiting block 10 is used to prevent the stud 65 from disengaging from the operating wheel 66.

[0035] Specifically, the support column 1, the upper disc 2, and the metal bracket 4 are made of titanium-aluminum alloy.
