Abstract
Description
Technical Field
[0001] This utility model relates to the field of electroplated parts cleaning device, specifically, to an electroplated parts cleaning device. Background Technology
[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance, and enhancing aesthetics. In the steel structure connections of buildings, electroplated parts such as bolts are used. During the production and processing of electroplated parts, cleaning equipment is used to remove processing residues.
[0003] There are many existing technologies for electroplating cleaning equipment, such as:
[0004] Chinese patent application CN202222282019.2 discloses a cleaning device for electroplated parts, specifically a cleaning mechanism for electroplating processes. The device includes a protective housing, a cleaning mechanism housed within the protective housing, a drying mechanism housed within the protective housing, and a fixing mechanism housed within the protective housing. The fixing mechanism includes a lifting component, a driving component, multiple U-shaped frames, multiple connecting rods, and multiple movable plates. The lifting component is housed within the protective housing, the driving component is housed within the lifting component, each U-shaped frame is mounted on the lifting component, each connecting rod slides through one side of the outer wall of the U-shaped frame, and each movable plate is fixedly mounted on one side of the outer wall of the connecting rod. The fixing mechanism can fix multiple electroplated workpieces, preventing collisions between workpieces during cleaning that could scratch the surface of the electroplated workpieces and affect their appearance. It also prevents workpieces from piling up, which could lead to incomplete cleaning.
[0005] However, existing cleaning devices typically employ a single fixed clamping method, which has certain drawbacks. The clamping area of the electroplated part is covered, preventing it from being thoroughly cleaned and creating cleaning blind spots that affect the subsequent use and quality of the electroplated part. Therefore, we propose a cleaning device for electroplated parts. Utility Model Content
[0006] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cleaning device for electroplated parts;
[0007] To achieve the above objectives, this utility model provides an electroplated parts cleaning device, including a housing. A lifting cylinder is fixedly connected to the top of the inner cavity of the housing. A lifting plate is fixedly connected to the piston rod end of the lifting cylinder. A horizontal drive component and a vertical drive component are provided at the bottom of the lifting plate. The horizontal drive component and the vertical drive component are stacked and staggered. Each end of the horizontal drive component and the vertical drive component is provided with a clamping block. The four clamping blocks are arranged in a circular array, and a clamping groove adapted to the size of the electroplated parts is formed between the four clamping blocks. The horizontal drive component and the vertical drive component are controlled by a PLC controller to alternately operate, realizing dynamic switching between the horizontal and vertical clamping positions. The horizontal drive component is used to drive the clamping blocks at both ends to move laterally closer and farther away, and the vertical drive component drives the clamping blocks at both ends to move longitudinally closer and farther away.
[0008] The beneficial effects of this utility model are:
[0009] By controlling the alternating movement of the first and second bidirectional hydraulic rods, the clamping position of the electroplated parts is dynamically switched. When one set of clamping blocks is clamped, the other set is released, exposing the area that was originally clamped and covered to the spray range of the cleaning nozzle, eliminating cleaning dead angles and improving the cleaning effect.
[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] As a further improvement to this technical solution, the inner wall of the clamping groove is movably connected to an anti-slip block. The anti-slip block slides radially or axially along the clamping groove, and its side and the inner wall of the clamping groove have linearly arranged adjustment holes. The position of the anti-slip block is locked by a fixing bolt passing through adjacent adjustment holes. A shock-absorbing rubber ring is sleeved on the outside of the fixing bolt, and the surface of the anti-slip block has anti-slip texture.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the anti-slip block can move in the clamping groove. By rotating the fixing bolt into the adjustment hole, the size of the clamping groove can be changed. The cooperation between the anti-slip block and the clamping groove forms an upper and lower limit structure, which effectively prevents the workpiece from shaking or shifting during the cleaning process. This ensures clamping stability while improving the versatility of the equipment and reducing the time and cost waste caused by changing the fixture.
[0013] As a further improvement to this technical solution, the lateral drive component includes a first mounting shell and a first bidirectional hydraulic rod, the first bidirectional hydraulic rod being disposed on the inner wall of the first mounting shell. The longitudinal drive component includes a second mounting shell and a second bidirectional hydraulic rod, the upper surface of the second mounting shell being fixedly connected to the bottom surface of the first mounting shell, and the second bidirectional hydraulic rod being disposed on the inner wall of the second mounting shell.
[0014] The beneficial effect of adopting the above-described further solution is that, by using the first mounting shell and the first bidirectional hydraulic rod together, the clamping blocks at both ends are driven to move horizontally closer or further away, achieving lateral clamping. By using the second mounting shell and the second bidirectional hydraulic rod together, the clamping blocks at both ends are driven to move vertically closer or further away, achieving longitudinal clamping. The bidirectional hydraulic rod provides stable power and uniform clamping force.
[0015] As a further improvement to this technical solution, a cleaning tank is provided on the bottom surface of the inner wall of the outer shell, and cleaning nozzles arranged at multiple angles are arranged around the inner wall of the cleaning tank. A water pump for providing cleaning fluid circulation is provided on the outside of the outer shell.
[0016] The advantages of adopting the above-mentioned further solutions are that the multi-angle nozzles ensure thorough cleaning without dead angles, remove stubborn stains, and the circulation system saves water resources and reduces operating costs.
[0017] As a further improvement to this technical solution, the inner wall of the outer shell is provided with a drying nozzle, and the side of the outer shell is provided with a transparent protective door with an airtight strip at its edge.
[0018] The beneficial effects of adopting the above-mentioned further solutions are that the drying nozzle quickly dries the workpiece after cleaning, preventing water stains from remaining, and the transparent protective door is equipped with an airtight strip, allowing observation of the operation while isolating liquid splashes.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In this adjustable precision machining fixture, the clamping position of the electroplated part is dynamically switched by controlling the alternating action of the first bidirectional hydraulic rod and the second bidirectional hydraulic rod. When one set of clamping blocks is clamped, the other set is released, exposing the area originally covered by the clamping to the spray range of the cleaning nozzle, eliminating cleaning dead angles and improving the cleaning effect.
[0021] On the other hand, by setting up clamping blocks and anti-slip blocks in the clamping grooves to cooperate with each other and using fixing bolts to fix them, the position can be adjusted to adapt to electroplated parts of different sizes. The cooperation between the anti-slip blocks and the clamping grooves forms an upper and lower limit structure, which effectively prevents the workpiece from shaking or shifting during the cleaning process, ensuring clamping stability while improving the equipment's versatility and reducing the time and cost waste caused by changing clamps.

[0028] 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.
[0029] Please see Figure 1-4 As shown, this embodiment provides an electroplated parts cleaning device, including a housing 1. A lifting cylinder 11 is fixedly connected to the top of the inner cavity of the housing 1. The lifting cylinder 11 uses compressed air as a power source to drive the electroplated parts to move up and down for immersion. The piston rod end of the lifting cylinder 11 is fixedly connected to a lifting plate 12. The bottom of the lifting plate 12 is provided with a horizontal drive 2 and a vertical drive 3. The horizontal drive 2 and the vertical drive 3 are stacked and staggered. Both ends of the horizontal drive 2 and the vertical drive 3 are provided with clamping blocks 4. The four clamping blocks 4 are arranged in a circular array, and the four clamping blocks 4 form a clamping groove 41 adapted to the size of the electroplated parts. The horizontal drive 2 and the vertical drive 3 are controlled by a PLC controller to alternately move, realizing dynamic switching between the horizontal and vertical clamping positions. The horizontal drive 2 is used to drive the clamping blocks 4 at both ends to move laterally closer and farther away, and the vertical drive 3 is used to drive the clamping blocks 4 at both ends to move longitudinally closer and farther away.
[0030] The improvement of this utility model is as follows:
[0031] like Figure 1-4As shown, in the prior art, after the electroplated part is clamped by a conventional clamping mechanism, the conventional clamping mechanism is moved downward by the lifting cylinder 11 for immersion cleaning. However, during cleaning, the clamping structure maintains the coverage of the outer wall of the electroplated part, which prevents the cleaning fluid from contacting the covered surface. Therefore, this utility model uses a transverse drive 2 to drive two clamping blocks 4 to move laterally to clamp the electroplated part, and a longitudinal drive 3 to drive two clamping blocks 4 to move longitudinally to clamp the electroplated part, forming a ring array of clamping squares around the electroplated part. When cleaning the covered area, the transverse drive 2 drives the two clamping blocks 4 to move laterally to spread. At this time, the longitudinal drive 3 still maintains the state of clamping the electroplated part. Then, the clamping blocks 4 at both ends of the transverse drive 2 disengage from the surface of the electroplated part, allowing the cleaning fluid to contact the covered area for cleaning without affecting stability.
[0032] Similarly, the longitudinal drive 3 drives the two clamping blocks 4 to spread longitudinally. At this time, the transverse drive 2 still maintains the state of gathering and clamping the electroplated part. Then, the clamping blocks 4 at both ends of the longitudinal drive 3 disengage from the surface covering position of the electroplated part, so that the cleaning liquid can contact the covering position for cleaning.
[0033] Based on the above, a more detailed technical solution is provided:
[0034] First, to achieve precise clamping and multi-directional adjustment of the electroplated parts, ensuring thorough cleaning and reducing blind spots, the transverse drive component 2 includes a first mounting shell 21 and a first bidirectional hydraulic rod 22, with the first bidirectional hydraulic rod 22 disposed on the inner wall of the first mounting shell 21. The longitudinal drive component 3 includes a second mounting shell 31 and a second bidirectional hydraulic rod 32. The upper surface of the second mounting shell 31 is fixedly connected to the bottom surface of the first mounting shell 21, and the second bidirectional hydraulic rod 32 is disposed on the inner wall of the second mounting shell 31. When clamping the electroplated parts, the transverse drive component 2 is activated, causing the first bidirectional hydraulic rod 22 to extend and push the clamping blocks 4 at both ends towards the center until the electroplated parts are clamped. When releasing the electroplated parts, the first bidirectional hydraulic rod 22 retracts, causing the clamping blocks 4 to move away from each other. When clamping the electroplated parts, the longitudinal drive component 3 is activated as needed, causing the second bidirectional hydraulic rod 32 to extend or retract, thereby controlling the longitudinal movement of the clamping blocks 4 and achieving longitudinal clamping or releasing of the electroplated parts. Under the action of the transverse drive 2 and the longitudinal drive 3, the clamping blocks 4 move closer or further apart to clamp electroplated parts of different sizes. After the electroplated part is placed into the clamping groove 41, the action of the transverse drive 2 and the longitudinal drive 3 is adjusted to make the clamping blocks 4 conform to the shape of the electroplated part and firmly clamp it, ensuring that the electroplated part will not shift or shake during the cleaning process.
[0035] Secondly, to perform the cleaning operation on the electroplated parts, a cleaning tank 5 is provided on the bottom inner wall of the outer casing 1. Cleaning nozzles 6 arranged at multiple angles are arranged around the inner wall of the cleaning tank 5. A water pump for circulating the cleaning solution is provided on the outside of the outer casing 1. An appropriate amount of cleaning solution is added to the cleaning tank 5, and then the clamped electroplated parts are sent into the cleaning tank 5 via a lifting cylinder 11, ensuring the electroplated parts are completely immersed in the cleaning solution. The cleaning nozzles 6 then perform a comprehensive cleaning of the electroplated parts. During the cleaning process, the water pump connects the cleaning tank 5 and the cleaning nozzles 6, providing the power for the circulation of the cleaning solution. A motor drives an impeller to rotate, drawing and pressurizing the cleaning solution from the cleaning tank 5, and then delivering it to the cleaning nozzles 6, forming a circulating cleaning solution system. The cleaning solution is sprayed from the cleaning nozzles 6. The angle and spray pressure of the cleaning nozzles 6 are adjusted according to the shape and position of the electroplated parts to ensure that the cleaning solution evenly covers the surface of the electroplated parts, achieving a good cleaning effect.
[0036] Furthermore, considering that the electroplated parts may slip due to water flow impact or equipment vibration during the cleaning process, an anti-slip block 42 is movably connected to the inner wall of the clamping groove 41. The anti-slip block 42 slides radially or axially along the clamping groove 41, and its side has linearly arranged adjustment holes 43 on the inner wall of the clamping groove 41. The position of the anti-slip block 42 is locked by a fixing bolt 44 passing through adjacent adjustment holes 43. A shock-absorbing rubber ring is sleeved on the outside of the fixing bolt 44, and the surface of the anti-slip block 42 has anti-slip texture. According to the actual size and shape of the electroplated parts, the anti-slip block 42 slides radially or axially along the clamping groove 41, selects a suitable position for the adjustment hole 43, and then locks the position of the anti-slip block 42 by the fixing bolt 44 passing through adjacent adjustment holes 43 to fix the anti-slip block 42. The shock-absorbing rubber ring is installed on the fixing bolt 44 and is in close contact with the anti-slip block 42 and the inner wall of the clamping groove 41, playing a shock-absorbing role during equipment operation. When clamping the electroplated parts, the anti-slip block 42 contacts the surface of the electroplated parts, and the anti-slip texture on its surface prevents the electroplated parts from sliding.
[0037] Furthermore, considering that water stains will adhere to the surface of the electroplated parts after cleaning, a drying nozzle 7 is installed on the inner wall of the outer casing 1 to improve the drying speed of the electroplated parts after cleaning. A hot air blower is installed on the outside of the outer casing 1. The air outlet of the hot air blower is connected to the drying nozzle 7 through a hot air duct. The hot air duct extends from the air outlet of the hot air blower, passes through the wall of the outer casing 1, and connects to the drying nozzle 7 inside. A transparent protective door is installed on the side of the outer casing 1, and its edge is equipped with an airtight strip. When the electroplated parts are lifted from the cleaning tank 5 and leave the cleaning solution, the hot air blower is started to draw in outside air through the air inlet. The air is heated when it passes through the heating element (such as an electric heating wire, gas burner, or heat pump) to form high-temperature hot air. The built-in fan forces the heated hot air out through the air outlet and guides it to the drying nozzle 7 through the hot air duct, ensuring that the hot air can be efficiently and accurately delivered to the position that needs to be dried and evenly sprayed onto the surface of the electroplated parts, so that the electroplated parts can be dried quickly. The transparent protective door is typically connected to the side of the outer casing 1 via hinges, enabling its opening and closing. During operation, operators can observe the clamping, cleaning, and drying of the electroplated parts through the transparent protective door. When it is necessary to insert or remove the electroplated parts, the transparent protective door is opened; after the operation is completed, the protective door is closed, at which point the airtight strip automatically adheres, ensuring the device's airtightness.
[0038] Based on the above, the specific structure will be disclosed in detail:
[0039] In practical use, the electroplated parts cleaning device of this utility model involves opening the transparent protective door and placing the electroplated parts to be cleaned into the clamping groove 41 formed by four clamping blocks 4, ensuring that the electroplated parts are initially placed in a suitable position. Based on the actual size and shape of the electroplated parts, the anti-sliding blocks 42 are slid radially or axially along the clamping groove 41. After adjusting to a suitable position, the anti-sliding blocks 42 are locked in place by fixing bolts 44 passing through adjacent adjustment holes 43, further enhancing the clamping stability of the electroplated parts. The transparent protective door is then closed, ensuring a good seal with the airtight strip. The PLC controller is activated, and the horizontal drive component 2 and the vertical drive component 3 operate alternately under the controller's control. The first bidirectional hydraulic rod 22 of the horizontal drive component 2 extends, causing the clamping blocks 4 at both ends to move laterally closer. Simultaneously, the second bidirectional hydraulic rod 32 of the vertical drive component 3 also extends or retracts as needed, causing the clamping blocks 4 at both ends to move longitudinally closer. This causes the four clamping blocks 4 to gradually conform to the shape of the electroplated parts, firmly clamping the electroplated parts within the clamping groove 41, forming a stable clamping state. The piston rod of the lifting cylinder 11 extends, pushing the lifting plate 12 downward, thereby causing the clamping mechanism holding the electroplated part to move downward as well, slowly sending the electroplated part into the cleaning tank 5 until the electroplated part is completely immersed in the cleaning solution. The water pump starts, drawing and pressurizing the cleaning solution from the cleaning tank 5, and delivering it to the multi-angle cleaning nozzles 6 surrounding the inner wall of the cleaning tank 5. The cleaning nozzles 6 spray the cleaning solution onto the electroplated part at a set angle and pressure, rinsing the surface of the electroplated part from all directions and multiple angles, removing stains and impurities from the surface. During the spraying process, the cleaning solution continuously impacts the surface of the electroplated part, and due to the action of the water pump, the cleaning solution forms a circulating flow within the cleaning tank 5, ensuring the continuity and uniformity of the cleaning effect. When the cleaning is completed, the piston rod of the lifting cylinder 11 retracts, pulling the lifting plate 12 upward, raising the clamping mechanism holding the electroplated part from the cleaning tank 5, so that the electroplated part is removed from the surface of the cleaning solution. During or after the electroplated part is raised, a hot air blower is activated to draw in outside air through the air inlet. The air is heated as it passes through the heating element, forming high-temperature hot air. The built-in fan forces the heated air out through the air outlet and guides it through the hot air duct to the drying nozzle 7, ensuring that the hot air is efficiently and accurately delivered to the drying location and evenly sprayed onto the surface of the electroplated part. After cleaning and drying, the PLC controller is activated again. Under the control of the controller, the horizontal drive component 2 and the vertical drive component 3 alternately move, causing the clamping block 4 to loosen its grip on the electroplated part. The first bidirectional hydraulic rod 22 of the horizontal drive component 2 retracts, moving the clamping block 4 laterally away. The second bidirectional hydraulic rod 32 of the vertical drive component 3 also moves accordingly, moving the clamping block 4 longitudinally away. The transparent protective door is opened, and the operator removes the dried electroplated part from the clamping groove 41, completing the entire cleaning process.
