Description

Technical Field

[0001] This utility model relates to the field of cylinder chromium plating, specifically to a high-efficiency auxiliary anode device for rapid, precise, and effective cylinder bore chromium plating. Background Technology

[0002] Electroplating of the inner bore of mining hydraulic cylinders commonly employs a copper-tin alloy plating process. This is because copper-tin alloy plating solutions offer strong coverage and depth, resulting in low porosity and high corrosion resistance. However, copper-tin alloy plating suffers from low hardness and poor wear resistance, making the inner bore plating of the cylinder easily scratched. While chromium plating can effectively improve these issues, its poor depth and uniformity require high conductivity of the mounting hardware, a large auxiliary anode area, and precise alignment. Therefore, chromium plating of the inner bore of cylinders is less commonly used in mining hydraulic cylinders.

[0003] Currently, in chrome plating equipment for the inner bore of mining hydraulic cylinders, the anode rods are typically made of lead-tin alloy. Lead-tin alloy has poor conductivity and a high density, significantly increasing the overall weight of the anode rod, often approaching or exceeding 100 kilograms. Given this, the anode rod needs to be moved, which places higher demands on its conductivity and connection method. Existing technologies often use a hanging method to install the anode rod, with a hook at the top connecting it to an anode flybar for movement and positioning. However, due to the lack of overall fixation between the anode rod and the flybar, the connection structure lacks stability, causing the anode rod to wobble during movement or electroplating. This problem affects the accuracy and stability of the alignment between the anode rod and the cylinder bore, reducing the efficiency of accurate alignment and the chrome plating effect. Furthermore, it can lead to poor conductive contact, causing localized overheating of the hook, and in severe cases, even hook breakage.

[0004] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a fast, accurate, and efficient auxiliary anode device for chrome plating of cylinder bores. The copper clamp plate serves as an intermediate connector between the copper core and the anode copper busbar, resulting in a stable connection structure that enables the anode rod to be quickly and accurately aligned and to conduct electricity efficiently and stably.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes an anode rod, which includes an outer cylindrical rod body, a copper core, and copper clamping plates. A portion of the copper core is wrapped inside the outer cylindrical rod body, and the exposed portion of the copper core is clamped between two copper clamping plates. An anode copper busbar for driving the movement of the anode rod is also clamped between the two copper clamping plates.

[0007] In this application, a copper clamp is used as an intermediate connector between the copper core and the anode copper busbar. This ensures a stable connection between the copper core and the anode copper busbar while maintaining high conductivity. This allows the anode copper busbar to drive the anode rod to move quickly and accurately, enabling the anode rod to be accurately and quickly inserted into the cylinder bore. The stable connection structure also prevents the anode rod from wobbling during the chrome plating process, ensuring the alignment stability between the anode rod and the cylinder bore and guaranteeing the chrome plating effect. Furthermore, the copper busbar, copper clamp, and copper core have efficient and stable conductivity, effectively reducing voltage drop and energy loss and preventing poor contact problems.

[0008] Based on the above, the exposed portion of the copper core is designed in the shape of a strip to enhance conductivity and connection strength by increasing the contact area.

[0009] The exposed copper core in the slatted section helps to enhance the guidance and structural strength of the anode rod.

[0010] Based on the above, the anode rod also includes a copper pad, which is disposed between the copper core and the copper clamp, and is used to increase the distance between the two copper clamps.

[0011] The spacing between the two copper plates is adapted to the thickness of the anode copper busbar by using a copper pad, ensuring that the copper plate surface and the anode copper busbar can be in close contact and connected, thus ensuring the conductivity and connection strength of the anode rod.

[0012] Based on the above, the anode rod also includes a reinforcing plate, and a reinforcing plate is provided on the outer side of each of the two copper clamps. The reinforcing plate is used to enhance the connection strength when the copper clamps are connected to the copper core and the copper clamps are connected to the anode copper busbar.

[0013] By using a reinforcing plate, the thickness of the copper clamp can be reduced to a certain extent while ensuring conductivity. This compensates for the lack of structural strength caused by the reduced thickness of the copper clamp, enhances the overall structural strength of the anode rod and the connection strength with the anode copper busbar, and helps to increase the overall structural strength of the anode rod and reduce the overall manufacturing cost of the anode rod.

[0014] Based on the above, the copper core, the copper pad, the copper clamp, and the reinforcing plate are connected by bolts to form a multi-layer plate structure, and the anode copper busbar, the copper clamp, and the reinforcing plate are connected by bolts to form a multi-layer plate structure.

[0015] The anode rod is bolted together to form a multi-layer plate structure and connected to the anode copper busbar. This makes it easy to disassemble and reassemble the anode rod itself, facilitates the connection between the anode rod and the anode copper busbar, and ensures high structural strength.

[0016] Based on the above, the end of the reinforcing plate away from the outer cylindrical rod is cantilevered outward relative to the copper clamp plate to form a cantilever section, and the cantilever section is provided with a hanging hole.

[0017] The cantilever section and hanging holes facilitate the installation and fixation of the anode rods onto the anode copper busbars via hoisting assistance, which is beneficial for the loading and unloading of the anode copper busbars.

[0018] Based on the above, the strip-shaped exposed portion of the copper core is centered and aligned with the axis of the outer cylindrical rod. A copper pad is provided on each side of the exposed portion of the copper core, and the two copper pads have the same thickness.

[0019] By using two copper pads of the same thickness, the anode rod is centered relative to the anode copper busbar, which ensures the accuracy of parameters such as the load weight, precision, and stroke of the anode copper busbar on the anode rod, guarantees the stability of the anode rod when the anode copper busbar moves it, and ensures that the anode rod is quickly and accurately positioned.

[0020] Based on the above, the top end of the outer cylindrical rod is provided with an insulating strip that wraps around the surface of the outer cylindrical rod.

[0021] By placing the insulating tape at the liquid level during the chrome plating process, the anode rod can be effectively protected from liquid line corrosion.

[0022] Based on the above, the portion of the copper core located within the outer cylindrical rod body has several through holes.

[0023] Through holes can enhance the connection strength between the outer cylindrical rod and the copper core, preventing the copper core from accidentally coming out of the outer cylindrical rod.

[0024] Based on the above, the anode copper busbar is a component of the anode flybar.

[0025] The anode rod is moved by the anode copper busbar of the anode flybar, which facilitates the loading and unloading of the anode rod and ensures that the anode rod is quickly and accurately positioned.

[0026] This utility model has substantial features and progress compared to the prior art. Specifically, in this application, a copper clamp is used as an intermediate connecting member between the copper core and the anode copper busbar. The connection structure is stable, enabling the anode rod to be quickly and accurately aligned and conduct electricity efficiently and stably. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the overall structure and exploded structure of this utility model; Figure 2 This is an exploded structural diagram of the present invention from another perspective; In the figure, the attached labels are: outer cylindrical rod 1, copper core 2, copper clamping plate 3, copper pad 4, reinforcing plate 5, hanging hole 6, insulating tape 7, fixing pin 8, anode copper busbar 9. Detailed Implementation

[0028] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0029] Example 1 like Figure 1 , Figure 2 As shown, the high-efficiency auxiliary anode device for rapid and precise cylinder bore chromium plating in this embodiment includes an anode rod, which comprises an outer cylindrical rod body 1, a copper core 2, and copper clamping plates 3. A portion of the copper core 2 is enclosed within the outer cylindrical rod body 1, and the exposed portion of the copper core 2 is clamped between two copper clamping plates 3. An anode copper busbar 9 for moving the anode rod is also clamped between the two copper clamping plates 3. The copper core 2 can be arranged in a manner where it is set along the axial direction of the outer cylindrical rod body 1, so that the exposed portion of the copper core 2 extends outward from one end of the outer cylindrical rod body 1.

[0030] The scheme of wrapping a copper core 2 with an outer cylindrical rod 1 has two advantages. First, the copper core 2 can improve the conductivity of the outer cylindrical rod 1, reduce voltage drop and energy loss, and make the anode rod have high conductivity. Second, the copper core 2 can improve the overall structural strength of the outer cylindrical rod 1 and enhance its durability.

[0031] The outer cylindrical rod 1 is made of lead-based alloy material, such as lead-tin alloy, to ensure the smooth progress of the chrome plating operation.

[0032] The cylindrical structure of the outer cylindrical rod 1 ensures the uniformity of chromium plating when performing chromium plating on the inner bore of the cylinder.

[0033] Two copper clamps 3 are used to clamp the copper core 2 and the anode copper busbar 9. On the one hand, clamping the anode copper busbar 9 and the copper core 2 together between the two copper clamps 3 provides a higher connection strength compared to hook connection, avoiding connection failures such as shaking during the movement of the anode rod by the anode copper busbar 9. No manual intervention or calibration is required, thus enabling the anode rod to be quickly and accurately positioned. On the other hand, based on the stable connection, the two copper clamps 3 act as intermediate conductors, providing a stable electrical connection between the anode copper busbar 9 and the copper core 2. This ensures efficient and stable conductivity between the anode rod and the anode copper busbar 9, preventing situations where insufficient conductivity affects the chromium plating efficiency.

[0034] The copper core 2 and copper clamp 3 can be made of copper to further enhance conductivity.

[0035] One or more anode rods can be optionally installed on the anode copper busbar 9.

[0036] The scheme of using the anode copper busbar 9 to drive the anode rod to move as a whole has the advantages of high overall structural strength. Therefore, the anode copper busbar 9 can be driven to move quickly and accurately, thereby driving the anode rod to move quickly and accurately through the copper clamp 3. This is conducive to realizing the automated movement control of the anode rod. Furthermore, due to the high conductivity of the anode copper busbar 9, after it moves into place, it can conduct electricity efficiently through the anode copper busbar 9, copper clamp 3, and copper core 2, which can improve the overall chromium plating efficiency.

[0037] In this embodiment, the copper clamp 3 serves as an intermediate connector between the copper core 2 and the anode copper busbar 9. This ensures a stable connection between the copper core 2 and the anode copper busbar 9 while maintaining high conductivity. This allows the anode copper busbar 9 to drive the anode rod to move quickly and accurately, enabling the anode rod to be accurately and quickly inserted into the cylinder bore. The stable connection structure also prevents the anode rod from wobbling during the chrome plating process, ensuring the alignment stability between the anode rod and the cylinder bore and guaranteeing the chrome plating effect. Furthermore, the copper busbar 9, copper clamp 3, and copper core 2 have efficient and stable conductivity, effectively reducing voltage drop and energy loss and preventing poor contact problems.

[0038] Example 2 Based on Example 1, the exposed portion of the copper core 2 is in the shape of a strip, so that the surface of the copper core 2 contacts the surface of the copper clamp 3 (or the copper pad 4 in Example 3). This can enhance conductivity and connection strength by increasing the contact area, which is beneficial to enhancing the guidance and structural strength of the anode rod.

[0039] The copper core 2 can be made entirely of strips, which gives the anode rod the advantages of simple structure and low manufacturing cost.

[0040] The portion of the copper core 2 inside the outer cylindrical rod 1 can also adopt a cylindrical structure, which can improve the uniformity of chromium plating to a certain extent.

[0041] Example 3 Based on Embodiment 1 or Embodiment 2, the anode rod also includes a copper pad 4, which is disposed between the copper core 2 and the copper clamp 3. The copper pad 4 is used to increase the distance between the two copper clamps 3 so that the distance between the two copper clamps 3 is adapted to the thickness of the anode copper busbar 9, ensuring that the surface of the copper clamp 3 and the anode copper busbar 9 can be tightly connected and in contact, thus ensuring the conductivity and connection strength of the anode rod.

[0042] In this embodiment, the number of copper pads 4 can be one, two, or more.

[0043] Example 4 Based on Embodiment 1, Embodiment 2 or Embodiment 3, the anode rod also includes a reinforcing plate 5. Each of the two copper clamps 3 is provided with a reinforcing plate 5 on its outer side. The reinforcing plate 5 is used to enhance the connection strength when the copper clamps 3 are connected to the copper core 2 and the copper clamps 3 are connected to the anode copper busbar 9.

[0044] Reinforcing plate 5 can be made of steel plate.

[0045] The difference between this embodiment and Embodiments 1, 2, or 3 is that in Embodiments 1, 2, or 3, a copper clamp plate 3 can be used as the main force-bearing component connecting the copper core 2 and the anode copper busbar 9, and the copper clamp plate 3 is used as the main load-bearing component to ensure the connection strength. This requires a copper clamp plate 3 of sufficient thickness to meet the structural strength requirements. In this embodiment, a reinforcing plate 5 is used as the main force-bearing component connecting the copper core 2 and the anode copper busbar 9, which can compensate for the structural deficiencies of the copper clamp plate 3 itself while reducing the thickness of the copper clamp plate 3.

[0046] By using the reinforcing plate 5, the thickness of the copper clamp plate 3 can be reduced to a certain extent while ensuring conductivity, and the structural strength of the anode rod can be compensated for by the reduction in the thickness of the copper clamp plate 3. This enhances the overall structural strength of the anode rod and the connection strength with the anode copper busbar 9, which is beneficial to increasing the overall structural strength of the anode rod and reducing the overall manufacturing cost of the anode rod.

[0047] Example 5 Based on Embodiment 2, Embodiment 3 or Embodiment 4, the copper core 2, copper pad 4, copper clamp 3 and reinforcing plate 5 are connected by bolts to form a multi-layer plate structure, and the anode copper busbar 9, copper clamp 3 and reinforcing plate 5 are connected by bolts to form a multi-layer plate structure.

[0048] The copper core 2, copper pad 4, copper clamp 3, and reinforcing plate 5 can be provided with two rows of four through holes, which are connected by bolts passing through the four through holes, so that the anode rod itself has high structural strength and electrical conductivity.

[0049] The anode copper busbar 9, copper clamp plate 3, and reinforcing plate 5 can be provided with two rows of four through holes. The connection is made by bolts passing through the four through holes, so that the anode rod and the anode copper busbar 9 have high connection strength and conductivity.

[0050] When the anode rod does not include the copper pad 4 in Example 3 and / or the reinforcing plate 5 in Example 4, a multi-layer plate structure can also be formed by bolting.

[0051] The anode rod is bolted together to form a multi-layer plate structure and connected to the anode copper busbar 9. This makes it easy to disassemble and reassemble the anode rod, facilitates its own assembly, ensures a strong connection with the anode copper busbar 9, and provides high structural strength.

[0052] Example 6 Based on embodiment 4, the end of the reinforcing plate 5 away from the outer cylindrical rod 1 is cantilevered outward relative to the copper clamp 3 to form a cantilever section, and the cantilever section is provided with a hanging hole 6.

[0053] Since the weight of the chrome-plated anode rods in the inner bore of mining hydraulic cylinders is often close to or exceeds 100 kilograms, it is difficult to load and unload the anode rods on the anode copper busbar 9 by relying solely on manual labor. Therefore, the cantilever section and the hanging hole 6 facilitate the installation and fixing of the anode rods on the anode copper busbar 9 by means of hoisting assistance, which is beneficial for the loading and unloading of the anode copper busbar 9.

[0054] Example 7 This embodiment is a further specific solution of embodiment 3. In this embodiment, two copper pads 4 are specifically provided to achieve the centered installation of the anode rod relative to the anode copper busbar 9.

[0055] Specifically, the strip-shaped exposed portion of the copper core 2 is centered and aligned with the axis of the outer cylindrical rod 1. A copper pad 4 is provided on each side of the exposed portion of the copper core 2. The two copper pads 4 have the same thickness, so that when the anode rod is installed on the anode copper busbar 9, its axis is located in the middle position between the two plates of the anode copper busbar 9, thus achieving the centered installation of the anode rod relative to the anode copper busbar 9.

[0056] By using two copper pads 4 of the same thickness, the anode rod is centered relative to the anode copper busbar 9, which ensures the accuracy of parameters such as the load weight, precision, and stroke of the anode copper busbar 9 on the anode rod, ensures the stability of the anode rod when it is moved by the anode copper busbar 9, and ensures that the anode rod is quickly and accurately positioned.

[0057] Example 8 Based on the above, the top of the outer cylindrical rod 1 is provided with an insulating strip 7 that wraps around part of the surface of the outer cylindrical rod 1. The insulating strip 7 can be made of materials such as PVC tape.

[0058] The insulating tape 7 can also wrap part of the exposed surface of the copper core 2.

[0059] The insulating tape 7 is positioned at the liquid level during the chrome plating operation, effectively protecting the anode rod and preventing corrosion of the liquid line.

[0060] Example 9 Based on the above, the portion of the copper core 2 located inside the outer cylindrical rod 1 is provided with several through holes 8. The outer cylindrical rod 1 can be integrally cast to enclose a portion of the copper core 2 inside, while the other portion of the copper core 2 extends outward. Therefore, the outer cylindrical rod 1 and the copper core 2 can enhance their connection strength through the through holes 8, preventing the copper core 2 from accidentally coming out of the outer cylindrical rod 1.

[0061] In other embodiments, a number of fixing pins 8 are provided through the portion of the copper core 2 located inside the outer cylindrical rod 1, with both ends of the fixing pins extending out of the surface of the copper core 2 and embedded in the outer cylindrical rod 1.

[0062] Example 10 Based on the above, the anode copper busbar 9 is a component of the anode flybar. The anode flybar drives the anode rod to move through the anode copper busbar 9, thereby providing the power for the movement of the anode rod.

[0063] The anode rod is moved by the anode copper busbar 9 of the anode flybar, which facilitates the loading and unloading of the anode rod and ensures that the anode rod is quickly and accurately positioned.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
