Description

Technical Field

[0001] This utility model belongs to the field of hardware processing technology, specifically relating to a surface treatment device for hardware parts. Background Technology

[0002] In the field of surface treatment of hardware parts, chemical immersion is widely used in pretreatment or functional treatment stages such as rust removal, degreasing, and the formation of a protective film due to its simple operation and suitability for batch processing. It involves immersing the workpiece in a specific chemical solution, using chemical reactions or physical dissolution to change the surface state of the hardware parts, laying the foundation for subsequent coating, rust prevention, and finishing processes.

[0003] However, existing chemical immersion processes for small metal parts typically involve placing multiple parts together in a container and then immersing the entire container in a chemical solution bath, relying on the agitation of the solution to achieve immersion. This method has significant drawbacks: due to the large number of small metal parts and their concentrated placement, some parts may come into contact with each other, while others may come into close contact with the container wall, forming a tight seal. This directly prevents these contact areas from fully contacting the chemical solution, hindering effective chemical reactions or physical dissolution in these areas. Consequently, the overall immersion effect is affected, leading to incomplete treatment of some parts, inconsistent surface finishes, and reduced product quality and production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a surface treatment device for hardware parts to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A surface treatment device for hardware parts, comprising:

[0007] Circular bearing;

[0008] The annular support body is a hollow cylinder. One end of the annular support body is open and has a cover. The end of the annular support body away from the cover is fixed with a base plate. Multiple through slots are opened on the circumferential side wall of the annular support body. A handle is rotatably mounted on the base plate.

[0009] A drive component, mounted on the base plate, is used to drive the annular support body to rotate;

[0010] The driving component includes:

[0011] A toothed ring is disposed on the side of the base plate away from the annular bearing.

[0012] The motor is fixedly connected to the handle;

[0013] The gear is connected to the output end of the motor and meshes with the gear ring.

[0014] Optionally, the end of the handle connected to the base plate is perpendicular to the base plate, and the handle is bent, with the end of the handle away from the base plate being parallel to the end of the handle connected to the base plate.

[0015] Optionally, the motor has a sealing shell on its outer side, and a support rod is fixed between the sealing shell and the handle.

[0016] Optionally, the sealed housing includes a first chamber and a second chamber, and the first chamber and the second chamber are separated from each other by a partition and are independent of each other, with the motor located inside the first chamber;

[0017] An electromagnetic coupler is provided on the output end of the motor, and the active end of the electromagnetic coupler is located inside the first chamber, while the driven end of the electromagnetic coupler is rotatably assembled inside the second chamber. The driven end of the electromagnetic coupler is connected to the gear.

[0018] Optionally, the handle is fitted with an isolation plate that matches the gear ring, and the edge of the isolation plate is rotatably and sealingly connected to the gear ring.

[0019] Optionally, the base plate is provided with a plurality of arc-shaped buffer plates on the side near the annular support, and the surface of the buffer plates is made of an elastic material.

[0020] Optionally, the lid has multiple through holes.

[0021] The beneficial effects of this utility model are:

At the same time, through the structural design of sealing and buffering, the equipment is guaranteed to operate stably in corrosive environments, reducing the risk of hardware damage and adapting to batch processing needs.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] like Figure 1-5 As shown, a surface treatment device for hardware parts includes:

[0033] Circular bearing 1;

[0034] The annular support body 1 is a hollow cylindrical shape. One end of the annular support body 1 is open and has a cover 11. The end of the annular support body 1 away from the cover 11 is fixed with a base plate 12. Multiple through slots are opened on the circumferential side wall of the annular support body 1. A handle 13 is rotatably mounted on the base plate 12.

[0035] Drive component 2, mounted on base plate 12, is used to drive the annular support body 1 to rotate;

[0036] Driver component 2 includes:

[0037] The gear ring 21 is located on the side of the base plate 12 away from the annular bearing 1;

[0038] Motor 22 is fixedly connected to handle 13;

[0039] Gear 23 is connected to the output end of motor 22 and meshes with gear ring 21.

[0040] The annular support body 1 is a hollow cylindrical structure and is the core supporting component of this equipment used to hold the hardware parts to be processed. Its cylindrical design provides uniform internal space, avoiding localized accumulation of hardware parts due to the irregular shape of the container. The multiple through-slots on the circumferential sidewalls are key channels for the entry and exit of chemical solutions. When the equipment is immersed in the chemical solution pool, the solution can quickly flow into the annular support body 1 through the through-slots, making full contact with the hardware parts, while ensuring the fluidity of the solution during immersion and avoiding localized imbalances in solution concentration that could affect the treatment effect.

[0041] The lid 11 is located at the open end of the annular support 1, serving as a sealing component to limit the movement of the internal hardware. When placing hardware, opening the lid 11 allows direct feeding into the annular support 1, making operation convenient. During soaking, the lid 11 closes to prevent the hardware from falling off the open end when the equipment rotates, while not obstructing the flow of solution (forming a solution circulation path with the through groove of the annular support 1), ensuring a balance between sealing and flow.

[0042] The base plate 12 is fixed to the end of the annular support 1 away from the cover 11, and plays a supporting and connecting role: on the one hand, it together with the annular support 1 and the cover 11 forms a closed receiving space, providing a stable bearing environment for the hardware; on the other hand, the base plate 12 is the mounting base of the drive assembly 2, used to fix the gear ring 21 and support the rotation assembly of the handle 13, so that the power of the drive assembly 2 can be stably transmitted to the annular support 1.

[0043] The handle 13 is rotatably mounted on the base plate 12 and is the operating and moving component of the equipment. Its rotational characteristics ensure that when the annular support 1 rotates under the action of the drive assembly 2, the handle 13 can remain relatively stationary, making it easy for operators to hold or connect to external robotic arms (such as multi-directional robotic arms) to realize the overall movement, transfer, or immersion / removal of the chemical solution pool of the equipment, thereby improving the flexibility and adaptability of the equipment.

[0044] Drive component 2 is the power system that enables the rotation of the ring-shaped support 1. Its core principle is gear transmission, and its specific functions are as follows:

[0045] Gear ring 21: Fixed on the side of the base plate 12 away from the annular support body 1, meshing with gear 23 to form a transmission pair, acting as a driven wheel to transmit the rotational power of gear 23 to the base plate 12, thereby driving the annular support body 1 to rotate synchronously.

[0046] Motor 22: As the main power source, it is fixedly connected to handle 13 (ensuring that motor 22 is stationary relative to handle 13). Its output end outputs torque to drive gear 23 to rotate. By controlling the output speed of motor 22, the rotation speed of the ring bearing 1 can be adjusted (usually low speed rotation) to avoid excessive speed causing hardware collision damage or solution splashing.

[0047] Gear 23: Connected to the output end of motor 22, meshing with gear ring 21, transmitting the power of motor 22 to gear ring 21. Through the reduction characteristics of gear transmission (based on the gear-to-gear ratio), the ring-shaped carrier 1 is rotated smoothly at low speed, causing the internal hardware to rotate relative to the container in the chemical solution. This breaks the contact state during traditional static soaking, reduces dead angles in solution contact, ensures that all parts can fully react with the chemical solution, and improves soaking uniformity and treatment effect.

[0048] Furthermore, the end of the handle 13 connected to the base plate 12 is perpendicular to the base plate 12, and the handle 13 is bent, with the end of the handle 13 away from the base plate 12 being parallel to the end of the handle 13 connected to the base plate 12.

[0049] The handle 13 is vertically connected to the base plate 12, which ensures the connection strength between the two and prevents deformation or loosening of the connection between the handle 13 and the base plate 12 due to the deviation of the force direction when the equipment moves as a whole (such as by transfer via a robotic arm) or the ring-shaped carrier 1 rotates, thus providing a stable support point for the equipment.

[0050] The curved handle 13 keeps the end furthest from the base plate 12 parallel to the connecting end, forming a grip / connection portion that meets ergonomic or robotic arm clamping requirements. When operated manually, the hand grip portion parallel to the connecting end of the base plate 12 reduces the angle of force on the hand and improves grip comfort. When used with an external multi-directional robotic arm, the parallel structure facilitates stable clamping or fixation by the robotic arm, ensuring stable posture of the equipment during movement, immersion in a solution tank, or removal, and avoiding operational deviations caused by irregular handle angles.

[0051] Furthermore, the motor 22 has a sealing shell 24 on its outer side, and a support rod 17 is fixed between the sealing shell 24 and the handle 13.

[0052] The sealing shell 24 is located on the outside of the motor 22, and its core function is to provide physical protection and a seal for the motor 22. Since this equipment needs to be completely immersed in a chemical solution bath for soaking treatment, and the chemical solution is mostly acidic, alkaline, or contains corrosive components, the sealing shell 24 can effectively prevent the solution from seeping into the motor 22, avoiding short circuits, corrosion, or performance failure caused by liquid intrusion. This ensures the stable operation of the motor 22 in humid and corrosive environments and extends its service life. At the same time, the sealing shell 24 can also isolate external dust and impurities from contaminating the motor 22, maintaining the cleanliness and working accuracy of the motor 22.

[0053] The support rod 17 is fixedly connected between the sealing shell 24 and the handle 13. Its main function is to rigidly fix the sealing shell 24 (and the internal motor 22) to the handle 13. Through the connection of the support rod 17, the position of the motor 22 relative to the handle 13 remains stable. When the handle 13 is stationary (or fixed by the robotic arm), the motor 22 will not shift with the rotation of the annular support body 1, ensuring that the gear 23 at the output end of the motor 22 can always maintain stable meshing with the gear ring 21 on the base plate 12, ensuring the continuity and reliability of power transmission. In addition, the length and structural design of the support rod 17 can reasonably distribute the force between the sealing shell 24 and the handle 13, preventing the connection from loosening due to vibration of the motor 22 during operation or external forces when the equipment moves as a whole, thus enhancing the overall stability of the equipment structure.

[0054] Furthermore, the sealed housing 24 includes a first chamber 241 and a second chamber 242, and the first chamber 241 and the second chamber 242 are separated from each other by a partition and are independent of each other. The motor 22 is located inside the first chamber 241.

[0055] An electromagnetic coupler 25 is provided on the output end of the motor 22. The active end of the electromagnetic coupler 25 is located inside the first chamber 241, and the driven end of the electromagnetic coupler 25 is rotatably assembled inside the second chamber 242. The driven end of the electromagnetic coupler 25 is connected to the gear 23.

[0056] The first chamber 241 serves as the housing space for the motor 22, providing it with an independent and enclosed environment. Since the motor 22 is an electrically driven component, it has extremely high requirements for sealing. The first chamber 241 can minimize the impact of the external environment (such as trace amounts of chemical solution penetration and moisture) on the motor 22, ensuring its stable electrical performance.

[0057] The second chamber 242 is used to house the driven end of the electromagnetic coupler 25 and the connecting part of the gear 23. Because this area needs to mesh with the external gear 23 (and gear ring 21), it inevitably comes into indirect contact with the external environment (such as solution vapor or small liquid splashes). The partition prevents moisture or liquid in the second chamber 242 from seeping back into the first chamber 241, further ensuring the safe operation of the motor 22. At the same time, the independent chambers also facilitate differentiated sealing designs for different areas (such as using a higher level of sealing technology for the first chamber 241).

[0058] The electromagnetic coupler 25 transmits power through electromagnetic induction: when the motor 22 drives the active end to rotate, the active end generates an alternating magnetic field, which drives the driven end in the second chamber 242 to rotate synchronously, thereby driving the gear 23 to rotate. This non-contact power transmission method, combined with the physical isolation of the chamber partition, can transmit the output torque of the motor while avoiding weak sealing points between the first chamber 241 and the second chamber 242 caused by mechanical connections (such as the transmission shaft passing through the partition), significantly improving the overall sealing performance of the sealing shell 24 and adapting to the working environment where the equipment is immersed in chemical solutions.

[0059] When the hardware components within the annular bearing 1 experience excessive load due to accumulation or jamming, a relative slippage can occur between the driving and driven ends of the electromagnetic coupler 25. This prevents the motor 22 from burning out due to overload, thus protecting the motor. Simultaneously, the characteristics of electromagnetic coupling can buffer the impact torque during startup, resulting in smoother meshing between the gear 23 and the gear ring 21, reducing wear on transmission components and extending the equipment's service life.

[0060] Furthermore, a partition plate 14 matching the gear ring 21 is fitted on the handle 13, and the edge of the partition plate 14 is rotatably connected to the gear ring 21 in a sealed manner.

[0061] Since the equipment needs to be vertically immersed in the chemical solution pool, the side of the base plate 12 furthest from the annular support 1 (i.e., the installation area of ​​the drive components 2 such as the gear ring 21 and gear 23) is easily exposed to the chemical solution. The isolation plate 14, through a sealed rotatable connection with the edge of the gear ring 21, forms a physical barrier between the handle 13 and the gear ring 21, effectively preventing the chemical solution from directly soaking or splashing onto the meshing parts of the gear ring 21 and gear 23. This avoids these metal transmission components from rusting, jamming, or experiencing a decrease in transmission efficiency due to contact with corrosive solutions, ensuring the long-term stable operation of the drive components 2.

[0062] The isolation plate 14 and the gear ring 21 are connected by a sealed rotational connection (such as through a sealing ring and a rotating shaft structure). This satisfies the requirement that the gear ring 21 rotates synchronously with the base plate 12 and the annular support 1, while maintaining good sealing during relative movement to prevent solution seepage due to gaps caused by rotation. At the same time, the isolation plate 14 is fitted onto the handle 13 and can remain relatively stationary with the handle 13 (or move synchronously with the external robotic arm), without interfering with the rotational movement of the annular support 1, ensuring that the power transmission of the drive assembly 2 is unimpeded.

[0063] Combined with the protection of the motor 22 by the sealing shell 24, the isolation plate 14 further improves the sealing system of the equipment, so that the core transmission part of the drive component 2 (the meshing part of the gear ring 21 and the gear 23) is in a relatively closed environment, reducing the risk of chemical solution corrosion to the transmission components. It forms a synergistic protection effect with the chamber isolation design of the sealing shell 24, and improves the reliability of the equipment under corrosive conditions.

[0064] Furthermore, the base plate 12 is provided with a plurality of arc-shaped buffer plates 15 on the side near the annular support body 1, and the surface of the buffer plates 15 is made of elastic material.

[0065] When the annular support 1 rotates under the drive assembly 2, the small hardware parts inside may shift in position due to centrifugal force or gravity, potentially colliding with the base plate 12 or the inner wall of the annular support 1. The arc-shaped buffer plate 15, through the deformation characteristics of elastic materials (such as rubber, silicone, etc.), can absorb the impact force generated by the collision, transforming rigid contact into flexible contact, effectively reducing scratches, deformation, or wear on the surface of the hardware parts. It is especially suitable for hardware parts with high precision requirements or easily damaged surfaces (such as small gears, precision connectors, etc.).

[0066] The arc-shaped design of the buffer plate 15 is adapted to the cylindrical inner wall of the annular support 1, which can guide the hardware to slide along the arc-shaped surface during rotation, reducing local accumulation caused by obstruction of sharp corners. The distribution of multiple buffer plates 15 can further disrupt the movement trajectory of the hardware, making the relative position between the hardware easier to change, avoiding long-term contact, thereby allowing for more complete contact with the chemical solution and improving the uniformity of immersion.

[0067] Furthermore, the lid 11 has multiple through holes 16.

[0068] When the entire device is vertically immersed in the chemical solution tank, the through-hole 16 and the through-groove on the circumferential side wall of the annular support 1 form a continuous solution flow path. The chemical solution can enter the interior of the annular support 1 from the cover 11 end through the through-hole 16, and at the same time, the through-groove on the side wall enables the exchange of solution between the inside and outside, ensuring that fresh chemical solution is in continuous contact with the internal hardware components, avoiding local concentration reduction caused by solution stagnation, and ensuring the sufficiency of the chemical reaction. Especially during the rotation of the annular support 1, the through-hole 16 can accelerate the disturbance and renewal of the solution inside, further improving the contact efficiency between the solution and the surface of the hardware components.

[0069] Overall, when using:

[0070] Place the hardware: With the device lid 11 facing upwards, open the lid 11 and place the small hardware to be processed into the annular support 1. After placement, close the lid 11 to ensure that the hardware is enclosed in the space composed of the annular support 1, the base plate 12 and the lid 11.

[0071] Equipment movement and immersion: By holding the equipment with handle 13 or connecting handle 13 to an external multi-directional robotic arm, the entire equipment can be moved and vertically immersed in the chemical solution pool until the annular support 1 and internal hardware are completely submerged in the solution.

[0072] Immersion is initiated by activating the drive assembly 2: The motor 22 of the drive assembly 2 is activated, and the output torque of the motor 22 is transmitted through the meshing of the gear 23 and the gear ring 21, driving the base plate 12 and the annular support body 1 to rotate at a low speed. During the rotation of the annular support body 1, the internal hardware moves with the solution, reducing the possibility of mutual contact or contact with the inner wall; at the same time, the chemical solution flows freely through the through grooves on the side wall of the annular support body 1 and the through holes 16 of the cover 11, ensuring that the solution is in full contact with the hardware and achieving uniform immersion.

[0073] Protection and stability during immersion: During immersion, the sealing shell 24 and electromagnetic coupler 25 ensure the sealing protection of the motor 22, the isolation plate 14 prevents the solution from corroding the meshing parts of the gear ring 21 and gear 23; the elastic buffer plate 15 reduces the impact damage to the hardware, and the handle 13 remains relatively still to ensure the stability of the equipment posture.

[0074] Removal and subsequent operations: After soaking, remove the device from the solution pool using handle 13 or a robotic arm, open the box cover 11 to remove the treated hardware, and complete one surface treatment process.
