Description

Technical Field

[0001] This utility model relates to the field of galvanizing equipment technology, and in particular to a galvanizing device for the surface of metal parts. Background Technology

[0002] As is well known, metal parts are prone to surface damage and performance degradation due to environmental corrosion during production and application. Therefore, galvanizing of metal surfaces has become a key process to improve the corrosion resistance of parts and extend their service life.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN210085606U discloses a zinc plating device for metal parts. Its core structure includes a tank containing zinc plating liquid, an electric telescopic rod connected to two side support plates, an upper plate that cooperates with the electric telescopic rod, and an anode rod powered by a storage battery. At the same time, an anode mud collection mechanism is set below the anode rod, and the surface treatment of metal parts is completed through the principle of electroplating zinc.

[0004] Regarding the aforementioned technologies, the inventors of this utility model have discovered that, after being put into use, when processing complex structural parts with deep holes, grooves, or irregular curved surfaces, the existing technologies cannot ensure that the current evenly covers all areas of the part surface. "Zinc plating blind spots" are easily formed in places such as the inner wall of deep holes and the bottom of grooves, resulting in unqualified galvanizing operations on the parts, causing rework and waste, and thus having certain limitations in use.

[0005] Therefore, it is necessary to propose a zinc plating device for metal parts. Utility Model Content

[0006] The purpose of this invention is to provide a zinc plating device for metal parts to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A zinc plating apparatus for metal parts, comprising:

[0009] Base;

[0010] A galvanizing liquid tank, wherein the galvanizing liquid tank is fixedly installed on a base and a lid is detachably connected to the galvanizing liquid tank;

[0011] Anode rod and cathode rod, both of which are mounted inside the galvanizing tank body via mounting bases;

[0012] The control panel is located on the outer wall of the zinc plating tank and is used to adjust the anode rod and cathode rod accordingly.

[0013] A drive motor is fixedly mounted on the cover, and a gear is fixedly connected to the output shaft of the drive motor.

[0014] Two connecting shafts are rotatably mounted inside the box cover, and each connecting shaft is equipped with a second gear, which meshes with a first gear.

[0015] Two connecting caps are symmetrically arranged at the bottom of the two connecting shafts, and the bottom of the connecting caps is threadedly connected to a placement cylinder, which has multiple through holes.

[0016] A support assembly disposed within a base for supporting the base in its place of use.

[0017] As a further embodiment of this utility model: the support assembly includes four support columns, all of which are disposed in the base through connecting grooves, and the other end of each support column is fixedly connected to a support seat.

[0018] As a further improvement of this utility model, the bottom of each of the multiple support seats is fixedly connected with an anti-slip rubber pad.

[0019] As a further embodiment of this utility model: a protective cover is fixedly connected to the box cover, the protective cover is fixedly installed outside the drive motor and gear one, and the ends of the two gears one that are far apart from each other are rotatably connected to the protective cover through a rotating shaft.

[0020] As a further improvement of this utility model, the connecting shaft is rotatably mounted inside the box cover via a constraint ring.

[0021] As a further improvement of this utility model: a strip handle is fixedly connected to the box cover, and an anti-slip rubber sleeve is provided on the outer fixed sleeve of the strip handle.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By setting up a support assembly, the base is supported and placed in the usage position through the cooperation of multiple support columns and support seats. The drive motor drives gear one to rotate through the output shaft. Gear one meshes with gear two on the connecting shaft, which can synchronously drive the connecting shaft to rotate, thereby driving the placement cylinder connected to the bottom connecting cover to rotate. Multiple through holes on the placement cylinder allow the zinc plating solution to fully penetrate into the cylinder. With the rotation of the placement cylinder, the current evenly covers the surface of the parts, the inner wall of deep holes, the bottom of the grooves, and other areas, ensuring the uniformity and pass rate of zinc plating. The placement cylinder and the connecting cover are threaded together, which facilitates the quick loading and unloading of metal parts of different specifications. The control panel can precisely control the working parameters of the anode and cathode rods, which can be flexibly adjusted according to the material of the parts and the zinc plating requirements. The protective cover of the box cover can protect the drive motor and gear structure from external impurities. Its overall structure is relatively simple. Compared with existing technologies, it has the advantages of high adaptability to complex parts, better zinc plating effect, and convenient operation, thus meeting the diverse zinc plating requirements of metal parts and significantly improving its production efficiency. It has good overall practicality and is conducive to widespread use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Please see Figures 1-4 In this embodiment of the present invention, a zinc plating device for metal parts includes:

[0032] Base 1;

[0033] The galvanizing liquid tank 2 is fixedly installed on the base 1, and the galvanizing liquid tank 2 is detachably connected to the tank cover 3;

[0034] Anode rod 4 and cathode rod 5 are both mounted inside the main body of zinc plating tank 2 via mounting base 6;

[0035] Control panel 7 is located on the outer wall of zinc plating tank 2 and is used to control the anode rod 4 and cathode rod 5 accordingly.

[0036] The drive motor 8 is fixedly mounted on the cover 3, and the output shaft of the drive motor 8 is fixedly connected to a gear 9;

[0037] Two connecting shafts 10 are rotatably mounted inside the cover 3, and each of the two connecting shafts 10 is equipped with a second gear 11, which meshes with a first gear 9.

[0038] Two connecting covers 12 are symmetrically arranged at the bottom of the two connecting shafts 10, and the bottom of the connecting cover 12 is threadedly connected to a placement cylinder 13, and the placement cylinder 13 is provided with multiple through holes 14.

[0039] A support assembly is disposed within the base 1 and is used to support the base 1 in the position of use.

[0040] This metal parts galvanizing device, during use, uses a support assembly to support the base 1 in the operating position, providing a stable foundation for subsequent galvanizing operations. Then, the cover 3 is opened, and the metal parts to be galvanized are placed into the placement cylinder 13, which is threadedly connected to the connecting cover 12. The placement cylinder 13 can be quickly disassembled and fitted according to the part specifications. The cover 3 is then closed, and sufficient galvanizing liquid is poured into the galvanizing tank 2, ensuring the placement cylinder 13 is completely submerged. The galvanizing operation is then started, and preset parameters are input via the control panel 7. Start the anode rod 4 and cathode rod 5, and simultaneously start the drive motor 8. Its output shaft drives the gear 9 to rotate. The gear 9 meshes with the gear 11 on the two connecting shafts 10, synchronously driving the connecting shafts 10 to rotate. This, in turn, drives the placement cylinder 13 to rotate together with the connecting shafts 10. The multiple through holes 14 on the placement cylinder 13 allow the zinc plating solution to fully penetrate into the cylinder. With the rotation of the parts, the current evenly covers the surface of the parts, the inner wall of the deep holes, and the bottom of the grooves, ensuring the uniformity of zinc plating. After zinc plating is completed, turn off the drive motor 8 and the electrodes, open the box cover 3, take out the placement cylinder 13, and pour out the finished parts.

[0041] exist Figures 1-3 The support assembly includes four support columns 15, all of which are set in the base 1 through connecting grooves, and the other end of each support column 15 is fixedly connected to a support seat 16. The bottom of each support seat 16 is fixedly connected to an anti-slip pad 17.

[0042] The galvanizing device for metal parts has a structure in which the support columns 15 are rigidly connected to the base 1 via the connecting groove. The four support columns 15 are evenly distributed to distribute the overall weight of the device to the support base 16, preventing the base 1 from tilting due to uneven force. This ensures that the galvanizing liquid level in the galvanizing tank 2 remains horizontal and does not affect the immersion effect of the parts. The support base 16 increases the contact area with the workstation floor, preventing the device from sinking in some areas and further improving the overall support stability. The anti-slip rubber pad 17 at the bottom can effectively resist the vibration generated by the operation of the drive motor 8 and the rotation of the parts, preventing the base 1 from shifting as a whole.

[0043] exist Figures 1-4 In the middle: A protective cover 18 is fixedly connected to the box cover 3. The protective cover 18 is fixedly installed outside the drive motor 8 and gear 9. The ends of the two gears 9 that are far apart from each other are rotatably connected to the protective cover 18 through the rotating shaft 19. The connecting shaft 10 is rotatably installed inside the box cover 3 through the constraint ring 20.

[0044] The galvanizing device for metal parts has a structure in which the protective cover 18 isolates the drive motor 8 and gear 9 from the outside world, effectively preventing liquid splashes and dust impurities that may be generated during the galvanizing operation from entering the transmission components, avoiding corrosion or jamming of the components, and extending the service life of the drive and transmission structure. Gear 9 is rotatably connected to the protective cover 18 through the rotating shaft 19, which can enhance the stability of the gear transmission process and prevent the gear from shifting due to the force of the cantilever. The constraint ring 20 on the outside of the connecting shaft 10 can form a radial limit on the connecting shaft 10, ensuring that the connecting shaft 10 always maintains coaxiality when rotating, preventing the placement cylinder 13 from rotating and shifting due to the shaking of the connecting shaft 10, thereby ensuring that the parts are subjected to uniform force in the galvanizing liquid.

[0045] exist Figures 1-4 In the middle: A strip handle 21 is fixedly connected to the lid of the box. The outer fixed sleeve of the strip handle 21 is equipped with an anti-slip rubber sleeve 22. The strip handle 21 provides a convenient force point for the operator to open and close the lid of the box 3, and can be easily operated without the aid of additional tools.

[0046] In this embodiment, the drive motor 8 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The drive motor 8 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0047] The implementation principle of the galvanizing device for metal parts according to this utility model embodiment is as follows: First, four support columns 15 are rigidly connected to the base 1 via connecting grooves, evenly transferring the overall weight of the device to the support seat 16. The support seat 16 prevents local sinking of the base 1 by increasing the contact area, while the bottom anti-slip rubber pad 17 resists the vibration generated by the operation of the drive motor 8 and the rotation of the parts by increasing the coefficient of friction, preventing the overall displacement of the device and ensuring that the liquid level in the galvanizing tank 2 is horizontal and the positions of the anode rod 4 and cathode rod 5 are stable, providing a precise and stable structural reference for the subsequent galvanizing process. Then, the metal parts to be galvanized are placed into the placement cylinder 13, and then the placement cylinder 13 and the base 16 are connected to the base 16. The connecting cover 12 is threaded on. After starting the drive motor 8, its output shaft drives the gear 9 to rotate. The gear 9 meshes with the gear 11 on the two connecting shafts 10, synchronously driving the connecting shafts 10 to rotate. This, in turn, drives the placement cylinder 13 to rotate smoothly with the connecting shafts 10. The multiple through holes 14 on the placement cylinder 13 allow the zinc plating solution to fully penetrate into the cylinder. Combined with the rotation of the parts, the current is evenly covered on the surface of the parts and the inner walls of deep holes, the bottom of the grooves, and other areas that are prone to forming "blind spots". At the same time, the current, voltage and other parameters of the anode rod 4 and the cathode rod 5 are precisely adjusted through the control panel 7. The electrolysis environment is optimized according to the material of the parts and the zinc plating requirements to ensure that the zinc layer is evenly adhered.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
