Description

Technical Field

[0001] This utility model relates to the field of chemical reagent detection technology, and in particular to a detection device for chemical reagents used in metal detection. Background Technology

[0002] Metal chemicals are chemicals used to treat metal surfaces. Metal degreasers are a type of chemical agent, referring to chemical agents used on metal surfaces to remove oil, grease, and stains.

[0003] To prevent chemical reagents from evaporating into the laboratory air and damaging the laboratory environment, and to prevent chemical reagents from splashing and potentially harming the human body, the prior art (Chinese utility model patent with announcement number CN117405661B) discloses a detection device for chemical reagents used in metals. This device can prevent toxic substances produced by chemical reagents during the detection process from spreading to the outside world, and can also achieve automated cleaning of the equipment, avoiding human contact with chemical reagents.

[0004] While it can achieve cleaning and anti-diffusion functions, it cannot test the performance of chemical agents, especially their cleaning power. This is because the cleaning power of chemical agents can vary depending on factors such as formulation, concentration, and usage conditions. If the cleaning power of chemical agents is not tested in advance during the production process and they are used directly, the cleaning power of the chemical agents may be insufficient, and contaminants may remain on the metal surface, leading to defects in subsequent processing and ultimately affecting the appearance and performance of the product. Therefore, it is necessary to conduct targeted testing of the cleaning power of chemical agents based on actual usage conditions before putting them into use.

[0005] Patent CN202311702773.X discloses a detection device and process for chemical reagents used in metals, relating to the technical field of chemical reagent detection. It includes a detection platform with a sealed detection chamber mounted on top for testing the chemical reagents. The chamber contains a detection mechanism for testing various chemical reagents used in metals, and also includes a cleaning mechanism for cleaning the instruments used after testing. However, this equipment is cumbersome to operate, has limited detection efficiency, and its application scenarios are relatively limited. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology by providing a testing device for chemical agents used on metals. This device simulates the dynamic conditions of workpieces in actual use and can simulate different working conditions, making it versatile. The reciprocating oscillating assembly controls the workpiece to oscillate within the chemical agent in the cleaning test unit, ensuring uniform contact between all parts of the workpiece and the chemical agent. This avoids cleaning dead zones caused by static or unidirectional movement, simulating the dynamic conditions of workpieces in actual use, making the test results more practically valuable, and allowing for more accurate verification and optimization of cleaning process parameters.

[0007] This utility model provides a testing device for metal chemical reagents, including a base, with a three-axis moving platform connected to the upper end of the base. A drying chamber, a weighing unit, an oiling unit, and a cleaning and testing assembly for storing metal reagents are fixedly connected inside the base. The drying chamber dries the workpiece using hot air drying, a common existing technology. The weighing unit, consisting of a weighing sensor and a container, is used to weigh the workpiece. The workpiece is weighed by zeroing the container's mass and then placing it inside. Weighing the product is also a mature existing technology. The oiling unit applies oil to one side of the workpiece's outer surface. The application method can be either spraying or brushing, both common existing technologies.

[0008] A swing test assembly is fixedly connected to one side of the Z-axis moving end of the three-axis moving platform. The swing test assembly includes a reciprocating swing unit.

[0009] The reciprocating swing unit includes: a motor, a turntable, a rod rotatably connected to one side of the turntable, a swing arm, a movable groove 3 opened inside the swing arm to accommodate the rod, and an electric gripper fixed to the lower end of the swing arm. The output shaft of the motor is fixedly connected to one side of the turntable, and the gripping end of the electric gripper is used to grip the workpiece.

[0010] The cleaning test assembly includes: a second housing fixed to the inner wall of the first base, a cavity opened inside the second housing, a cover connected to the upper end of the second housing, an opening opened inside the cover to facilitate the workpiece passing through, and an eddy current auxiliary testing unit connected inside the second housing; the cover is connected to the upper end of the second housing by bolts.

[0011] The eddy current-assisted measurement unit includes: a motor II fixed inside the housing II, a turntable II rotatably connected to the inner wall of the cavity, a turntable I rotatably connected to the lower end of the cover, and a column connecting the turntable I and the turntable II.

[0012] While the workpiece is being oscillated and cleaned, the second motor also drives the second turntable, the column, and the first turntable to rotate, thereby causing the cleaning agent inside the cavity to rotate and form a vortex. This simulates the dynamic cleaning conditions of oscillation and agitation of the workpiece in actual production. Under these dynamic conditions, the cleaning power of the cleaning agent is tested. The formation of the vortex increases the flow speed and impact force of the cleaning agent on the workpiece surface, thus more effectively peeling off and removing stubborn dirt. It also helps to evenly distribute the cleaning agent in the liquid, avoiding the problem of insufficient local agent concentration, and ensuring that the cleaning reaction is carried out evenly on the entire workpiece surface. This can better simulate the mechanical agitation conditions during metal cleaning in the actual production environment, making the test results closer to actual use conditions. Moreover, vortex cleaning is suitable for workpieces of different shapes and sizes, improving the versatility of the testing device.

[0013] Furthermore, the swing test assembly includes a housing 1 fixed to the outer surface of one side of the Z-axis moving end, a seat 2 connected inside the housing 1, a movable groove 2 opened inside the seat 2, and a reciprocating swing unit connected inside the seat 2.

[0014] Furthermore, the motor is fixedly connected inside the base, the turntable is rotatably connected to the inner wall of the movable groove, and the swing arm is rotatably connected to the inner wall of the movable groove.

[0015] Furthermore, two connecting columns are symmetrically fixed to both sides of the swing arm, and the other end of the two connecting columns is rotatably connected to the inner wall of the movable groove.

[0016] By adopting the above technical solution, the electric gripper is controlled to clamp the workpiece to be tested. Then, the three-axis moving platform is controlled to move the workpiece and send it into the drying oven for drying. After drying, the workpiece is sent to the weighing unit to weigh its initial mass (it should be noted that the electric gripper releases its grip after the workpiece enters the weighing unit, and then re-grips the workpiece after the weighing is completed). After weighing, the workpiece is sent to the oiling unit and oil is applied to one side of the outer surface of the workpiece. After oiling, the oil-coated workpiece is sent back to the weighing unit for mass measurement. After measurement, the workpiece is sent to the cleaning test assembly, which contains metal cleaning agent, and then... The motor drives the turntable to rotate, which in turn drives the rod to rotate. The rod is movably mounted in the movable slot. Therefore, when the rod rotates, it drives one end of the swing arm to swing left and right, causing the other end of the swing arm, which is fixed to the electric gripper, to swing as well. This causes the workpiece to swing in the metal cleaning agent, simulating the cleaning action conditions of the workpiece in actual production. This tests the cleaning power of the metal cleaning agent, making the test results more practically valuable and allowing for more accurate verification and optimization of cleaning process parameters. After swinging for a certain period of time, the motor resets, and the workpiece is then removed from the cleaning test assembly and placed back into the drying oven for drying. After drying, the cleaned workpiece is placed in the weighing unit for weighing.

[0017] Furthermore, the second seat is movably connected inside the first housing. The first housing has two symmetrically arranged movable slots. Two extension seats are slidably connected in the two movable slots. One end of each extension seat is connected to both sides of the second seat. A guide rod is fixed to the inner wall of the movable slot. The extension seat has a guide groove to accommodate the guide rod. A spring is sleeved on the outside of the guide rod. The two ends of the spring are connected to the extension seat and the inner wall of the movable slot.

[0018] Furthermore, two guide posts are symmetrically fixed to the inner wall of the cover, and a disc body is movably sleeved on the outside of the two guide posts. A second inclined flange is integrally formed at the lower end of the disc body, and a first inclined flange matching the second inclined flange is integrally formed at the upper end of the disc body. Two top posts are symmetrically connected to the upper end of the disc body. The upper ends of both top posts penetrate the cover body and extend outwards to push the extension seat to move.

[0019] Furthermore, a second spring is sleeved on the outside of the guide post, and the two ends of the second spring are respectively connected to the inner wall of the cover and the upper end of the disc. Two screw grooves are symmetrically opened on the upper end of the disc, and the lower ends of the two top posts are respectively screwed into the two screw grooves.

[0020] When the turntable rotates, it drives the first inclined flange to rotate. When the inclined surface of the first inclined flange contacts the inclined surface of the second inclined flange, it pushes the second inclined flange and the first disc body upward, compressing the second spring. At the same time, the top post can also extend from the cover body. When the workpiece passes through the opening and is inserted into the cavity, the lower end of the housing is close to the upper end of the cover body. Therefore, when the top post extends upward from the cover body, it pushes the extension seat upward within the first movable slot, compressing the first spring. When the extension seat moves upward, it drives the second seat body, the electric gripper, and the workpiece upward. When the first inclined flange separates from the second inclined flange, the second spring pushes the first disc body and the top post downward. As the top post moves downward, the first spring pushes the extension seat downward, thereby driving the workpiece downward. Therefore, the rotation of the turntable will cause the workpiece to move up and down reciprocally. This is to simulate the vertical cleaning of the workpiece in actual production (the workpiece is vertically placed into the cleaning agent and then lifted up, and the action is repeated to clean the workpiece). This allows for testing the cleaning power of the cleaning agent under such working conditions, and can also more accurately verify and optimize the cleaning process parameters. This application can simulate the cleaning power of chemical agents under different working conditions to determine the difference in the cleaning power of chemical agents on the same workpiece under different working conditions (oscillation, oscillation + agitation, vertical cleaning). It can also determine which working condition (oscillation, oscillation + agitation, vertical cleaning) can maximize the cleaning power of the chemical agent for different workpieces using the same chemical agent.

[0021] Furthermore, the turntable 2 is also connected to a cleaning test unit, which includes: a disc body 2 sleeved on the outside of the column, a bearing connected inside the disc body 2, a sleeve sleeved on the outside of the column and fixed at its lower end to the inner ring of the bearing, and multiple brush bristles fixed to the outer surface of the sleeve, and the outer ring of the bearing is fixed to the inner wall of the disc body 2.

[0022] Furthermore, the inner wall of the cavity is provided with toothed grooves, and the lower end of the turntable is rotatably connected to a gear that meshes with the toothed grooves. The lower end of the column passes through a bearing and is fixedly connected to one side of the gear.

[0023] Furthermore, a screw is screwed into the inside of the second disc, and the lower end of the screw passes through the second disc and is rotatably connected to the upper end of the second turntable. Multiple high-pressure nozzles are also fixed to the inner wall of the cavity, and a nozzle input end connected to the high-pressure nozzle is provided on the outer surface of the second housing.

[0024] While the second turntable rotates, it also drives the gear to rotate. Since the gear meshes with the tooth groove, the gear can also rotate on its own at the lower end of the second turntable as it rotates. The rotation of the gear drives the inner ring of the column and bearing to rotate. The rotation of the column can drive the sleeve and brush to rotate. The height of the second turntable can be adjusted by rotating the screw. When the second turntable rises, it can drive the sleeve and brush to rise, so that the brush can contact the outer surface of the workpiece. This simulates the working condition of vertical cleaning of the workpiece in the cleaning agent + rotating brushing, which is convenient for testing the cleaning power of the cleaning agent under this working condition.

[0025] The working principle of this utility model is as follows:

[0026] The electric gripper holds the workpiece to be tested, and then the three-axis moving platform moves the workpiece and sends it into a drying oven for drying. After drying, the workpiece is sent to the weighing unit to weigh its initial mass. After weighing, the workpiece is sent to the oiling unit, where oil is applied to one side of the workpiece's outer surface. After oiling, the oil-coated workpiece is sent back to the weighing unit for mass measurement. After measurement, the workpiece is sent to the cleaning test assembly, which contains metal cleaning agent. The oscillating test assembly causes the workpiece to oscillate in the cleaning agent, simulating the cleaning action conditions of the workpiece in actual production. The eddy current within the cleaning test assembly... The testing unit can drive the cleaning agent inside the cavity to rotate and form a vortex, simulating the dynamic cleaning conditions of workpiece swinging and agitation in actual production. At the same time, the top column inside the cover can move up and down, pushing the extension seat and workpiece to move up and down, simulating the dynamic cleaning conditions of vertical cleaning of workpieces in actual production. The brushing test section simulates the working conditions of vertical cleaning and rotating brushing of workpieces in cleaning agent. By simulating various working conditions, the cleaning power of the cleaning agent is tested. After cleaning, the workpiece is taken out from the cleaning test component and put back into the drying oven to dry. After drying, the cleaned workpiece is put into the weighing unit for weighing, thereby detecting the cleaning power of the cleaning agent.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] (1) This utility model is equipped with a reciprocating swing unit and a cleaning test component. By placing the workpiece into the cleaning test component and controlling the reciprocating swing unit to drive the workpiece to swing in the chemical agent in the cleaning test component, the workpiece is evenly contacted with the chemical agent, avoiding cleaning dead angles caused by static or unidirectional movement, simulating the dynamic conditions of the workpiece in actual use, making the test results more practically valuable, and more accurately verifying and optimizing the cleaning process parameters.

[0029] (2) This utility model is equipped with an eddy current auxiliary testing unit. The rotation of the motor drives the first turntable, the second turntable and the column to rotate, so that the chemical agent in the cavity forms an eddy current. The formation of the eddy current increases the flow speed and impact force of the cleaning agent on the surface of the workpiece, thereby more effectively peeling off and removing stubborn dirt. It also helps the cleaning agent to be evenly distributed in the liquid, avoiding the problem of insufficient local agent concentration, and ensuring that the cleaning reaction is carried out evenly on the entire surface of the workpiece. It can better simulate the mechanical stirring conditions during metal cleaning in the actual production environment, making the test results closer to the actual use conditions. Moreover, eddy current cleaning is suitable for workpieces of different shapes and sizes, improving the versatility of the testing device.

[0030] (3) By setting guide posts and extension seats, this utility model can push the disc body to move up and down inside the cover when the turntable rotates, thereby causing the guide posts to push the extension seats to move, so that the workpiece can move up and down in the chemical agent, increasing the friction between the liquid and the workpiece surface, which helps to peel off the dirt attached to the surface. The up and down movement can generate a vertical mechanical force, further destroying the combination of pollutants and the workpiece surface, improving the cleaning efficiency. On the one hand, it expands the detection diversity of the detection equipment, and can simulate the cleaning power of the chemical agent under different working conditions to detect the difference in the cleaning power of the chemical agent on the same workpiece under different working conditions. It can also determine which working conditions can maximize the cleaning power of the chemical agent when different workpieces are used with the same chemical agent. On the other hand, it can better simulate the up and down movement in actual production, and more accurately verify and optimize the cleaning process parameters. Attached Figure Description

[0043] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms, and other features not explicitly described in this technical solution are considered common technical features disclosed in the prior art.

[0044] Example 1

[0045] This embodiment provides a detection device for chemical reagents used in metal detection, such as... Figures 1-11 As shown, the system includes a base 1, with a three-axis moving platform 2 connected to the upper end of the base 1. Inside the base 1 are a drying chamber 4, a weighing unit 5, an oiling unit 6, and a cleaning and testing assembly 7 for storing metal reagents. The drying chamber 4 dries the workpiece 338 using hot air drying, a common existing technology. The weighing unit 5 is used to weigh the workpiece 338. It consists of a weighing sensor and a container. The container holds the workpiece 338; by zeroing the container's mass, the product is placed inside, thus achieving product weighing. Product weighing is also a mature existing technology. The oiling unit 6 applies oil to one side of the outer surface of the workpiece 338. The application method can be either spraying or brushing, both common existing technologies.

[0046] The swing test assembly 3 is fixedly connected to one side of the Z-axis moving end of the three-axis moving platform 2. The swing test assembly 3 includes a reciprocating swing unit 33.

[0047] The reciprocating swing unit 33 includes: a motor 334, a turntable 335, a rod 336 rotatably connected to one side of the turntable 335, a swing arm 331, a movable groove 332 opened inside the swing arm 331 to accommodate the rod 336, and an electric gripper 337 fixed to the lower end of the swing arm 331. The output shaft of the motor 334 is fixed to one side of the turntable 335, and the clamping end of the electric gripper 337 is used to clamp the workpiece 338.

[0048] like Figure 4 and Figure 6 As shown, the cleaning test assembly 7 includes: a second housing 71 fixed to the inner wall of the base 1, a cavity 711 opened inside the second housing 71, a cover 73 connected to the upper end of the second housing 71, an opening 731 opened inside the cover 73 to facilitate the passage of the workpiece 338, and an eddy current auxiliary testing unit 72 connected inside the second housing 71; the cover 73 is bolted to the upper end of the second housing 71.

[0049] The eddy current-assisted measurement unit 72 includes: a motor 722 fixed inside the housing 71, a turntable 723 rotatably connected to the inner wall of the cavity 711, a turntable 721 rotatably connected to the lower end of the cover 73, and a column 724 connected between the turntable 721 and the turntable 723.

[0050] While the workpiece 338 is being oscillated and cleaned, the operation of motor 722 also drives turntable 723, column 724, and turntable 721 to rotate, thereby causing the cleaning agent inside cavity 711 to rotate and form a vortex. This simulates the dynamic cleaning conditions of oscillation and agitation of the workpiece in actual production. Under these dynamic conditions, the cleaning power of the cleaning agent is tested. The formation of the vortex increases the flow speed and impact force of the cleaning agent on the workpiece surface, thus more effectively peeling off and removing stubborn dirt. It also helps to evenly distribute the cleaning agent in the liquid, avoiding the problem of insufficient local agent concentration, and ensuring that the cleaning reaction is carried out evenly on the entire workpiece surface. This can better simulate the mechanical agitation conditions during metal cleaning in the actual production environment, making the test results closer to the actual use conditions. Moreover, vortex cleaning is suitable for workpieces of different shapes and sizes, improving the versatility of the testing device.

[0051] In a specific embodiment, the swing test assembly 3 includes a housing 31 fixed to the outer surface of one side of the Z-axis moving end, a seat 32 connected inside the housing 31, a movable groove 321 opened inside the seat 32, and a reciprocating swing unit 33 connected inside the seat 32.

[0052] In a specific embodiment, the motor 334 is fixedly connected inside the base 32, the turntable 335 is rotatably connected to the inner wall of the movable groove 321, and the swing rod 331 is rotatably connected to the inner wall of the movable groove 321.

[0053] In a specific embodiment, two connecting posts 333 are symmetrically fixed to both sides of the swing rod 331, and the other ends of the two connecting posts 333 are rotatably connected to the inner wall of the movable groove 332.

[0054] By adopting the above technical solution, the electric gripper 337 is controlled to clamp the workpiece 338 to be tested. Then, the three-axis moving platform 2 is controlled to move the workpiece 338 and send it into the drying oven 4 for drying. After drying, the workpiece 338 is sent into the weighing unit 5 to weigh its initial mass. It should be noted that after the workpiece 338 enters the weighing unit 5, the electric gripper 337 cancels the clamping. After the weighing is completed, the workpiece 338 is clamped again. After the weighing is completed, the workpiece 338 is sent into the oiling unit 6 and oil is applied to one side of the outer surface of the workpiece 338. After the oiling is completed, the oil-covered workpiece 338 is sent into the weighing unit 5 again and its mass is measured. After the measurement is completed, the workpiece 338 is sent into the cleaning test assembly 7, which contains metal cleaning agent. Then, the drive motor 334 drives the turntable 335 to rotate. The rotation of the turntable 335 drives the rod 336 to rotate. The rod 336 is movably set in the movable slot. Within the second 321, when the rod 336 rotates, it drives one end of the swing rod 331 to swing left and right, causing the other end of the swing rod 331, which is fixed to the electric gripper 337, to swing as well. This causes the workpiece 338 to swing in the metal cleaning agent, simulating the cleaning action conditions of the workpiece in actual production, and testing the cleaning power of the metal cleaning agent. This makes the test results more practically valuable and can more accurately verify and optimize the cleaning process parameters. After swinging for a certain period of time, the motor 334 resets, and then the workpiece 338 is taken out from the cleaning test component 7 and put back into the drying oven 4 for drying. After drying, the cleaned workpiece 338 is placed in the weighing unit 5 for weighing. The formula for calculating the cleaning power is W2 = ((m1-m2) / (m1-m0)) × 100%, where W2 is the cleaning power; m0 is the mass of the workpiece 338; m1 is the mass of the workpiece 338 before cleaning; and m2 is the mass of the workpiece 338 after cleaning. The unit of mass is g.

[0055] like Figure 2 , Figures 6-9 As shown, in a specific embodiment, the second seat 32 is movably connected inside the first housing 31. The first housing 31 has two symmetrically arranged movable slots 311. Two extension seats 314 are slidably connected in the two movable slots 311 respectively. One end of the two extension seats 314 is connected to both sides of the second seat 32 respectively. A guide rod 312 is fixedly connected to the inner wall of the movable slot 311. A guide groove for accommodating the guide rod 312 is opened inside the extension seat 314. A spring 313 is sleeved on the outside of the guide rod 312. The two ends of the spring 313 are connected to the extension seat 314 and the inner wall of the movable slot 311 respectively.

[0056] In a specific embodiment, two guide posts 735 are symmetrically fixed to the inner wall of the cover 73, and a disc 732 is movably sleeved on the outside of the two guide posts 735. A second inclined flange 734 is integrally formed at the lower end of the disc 732, and a first inclined flange 733 matching the second inclined flange 734 is integrally formed at the upper end of the turntable 721. Two top posts 737 are symmetrically connected to the upper end of the disc 732. The upper ends of both top posts 737 penetrate the cover 73 and extend outward to push the extension seat 314 to move.

[0057] In a specific embodiment, a second spring 736 is sleeved on the outside of the guide post 735, and the two ends of the second spring 736 are respectively connected to the inner wall of the cover 73 and the upper end of the first disc 732. Two threaded grooves 738 are symmetrically opened on the upper end of the first disc 732, and the lower ends of the two top posts 737 are respectively screwed into the two threaded grooves 738.

[0058] When turntable 721 rotates, it drives inclined flange 733 to rotate. When the inclined surface of inclined flange 733 contacts the inclined surface of inclined flange 734, it can push inclined flange 734 and disc 732 upward, compressing spring 736. At the same time, the top post 737 can also extend from the cover 73. When workpiece 338 passes through opening 731 and is inserted into cavity 711, the lower end of housing 31 and the upper end of cover 73 are at the same time. Because of the close proximity, when the top post 737 extends upward from the cover 73, it can push the extension seat 314 upward within the movable groove 311, compressing the spring 313. When the extension seat 314 moves upward, it can drive the seat 32, the electric gripper 337, and the workpiece 338 upward. When the inclined flange 733 separates from the inclined flange 734, the spring 736 pushes the disc 732 and the top post 737 downward. As 737 moves downward, spring 313 pushes extension seat 314 downward, thereby causing workpiece 338 to move downward. Therefore, the rotation of turntable 721 will cause workpiece 338 to move up and down reciprocally. This is to simulate the vertical cleaning of workpieces in actual production (the workpiece is vertically placed into the cleaning agent and then lifted up, and the action is repeated to clean the workpiece). This allows for testing the cleaning power of the cleaning agent under such working conditions, and can also more accurately verify and optimize the cleaning process parameters. This application can simulate the cleaning power of chemical agents under different working conditions to determine the difference in the cleaning power of chemical agents on the same workpiece under different working conditions (oscillation, oscillation + agitation, vertical cleaning). It can also determine which working condition (oscillation, oscillation + agitation, vertical cleaning) can maximize the cleaning power of the chemical agent when using the same chemical agent on different workpieces.

[0059] like Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, in a specific embodiment, the turntable 723 is further connected to a cleaning test unit 74. The cleaning test unit 74 includes: a disc 741 sleeved on the outside of the column 724, a bearing 745 connected inside the disc 741, a sleeve 742 sleeved on the outside of the column 724 and fixed at its lower end to the inner ring of the bearing 745, and a plurality of bristles 743 fixed to the outer surface of the sleeve 742. The outer ring of the bearing 745 is fixed to the inner wall of the disc 741.

[0060] In a specific embodiment, a toothed groove 712 is also provided on the inner wall of the cavity 711, and a gear 725 that meshes with the toothed groove 712 is rotatably connected to the lower end of the turntable 723, and the lower end of the column 724 passes through the bearing 745 and is fixedly connected to one side of the gear 725.

[0061] In a specific embodiment, a screw 744 is screwed into the inside of the second disc 741, and the lower end of the screw 744 passes through the second disc 741 and is rotatably connected to the upper end of the second turntable 723. A plurality of high-pressure nozzles 75 are also fixedly connected to the inner wall of the cavity 711, and a nozzle input end 76 connected to the high-pressure nozzles 75 is provided on the outer surface of the second housing 71.

[0062] While the turntable 723 rotates, it also drives the gear 725 to rotate. Since the gear 725 meshes with the tooth groove 712, the gear 725 can also rotate on its own at the lower end of the turntable 723 while it rotates. The rotation of the gear 725 drives the inner ring of the column 724 and the bearing 745 to rotate. The rotation of the column 724 can drive the sleeve 742 and the brush bristles 743 to rotate. By rotating the screw 744, the height of the disc 741 can be adjusted. When the disc 741 rises, it can drive the sleeve 742 and the brush bristles 743 to rise, so that the brush bristles 743 can contact the outer surface of the workpiece 338. This simulates the working condition of vertical cleaning and rotating brushing of the workpiece in the cleaning agent, which is convenient for testing the cleaning power of the cleaning agent under this condition.

[0063] The working principle of this utility model is as follows:

[0064] The electric gripper 337 clamps the workpiece 338 to be tested. Then, the three-axis moving platform 2 moves the workpiece 338 and sends it into the drying oven 4 for drying. After drying, the workpiece 338 is sent to the weighing unit 5 to measure its initial mass. After weighing, the workpiece 338 is sent to the oiling unit 6, where oil is applied to one side of its outer surface. After oiling, the oil-covered workpiece 338 is sent back to the weighing unit 5 for mass measurement. After measurement, the workpiece 338 is sent to the cleaning test assembly 7, which contains metal cleaning agent. The oscillating test assembly 3 moves the workpiece 338 in the cleaning agent, simulating the cleaning conditions in actual production. The eddy current auxiliary testing unit 72 inside component 7 can drive the cleaning agent inside cavity 711 to rotate and form an eddy current, simulating the dynamic cleaning conditions of workpiece swinging and agitation in actual production. At the same time, the top column 737 inside cover 73 can move up and down, pushing extension seat 314 and workpiece 338 to move up and down, simulating the dynamic cleaning conditions of vertical cleaning of workpiece in actual production. The brushing test unit 74 simulates the working conditions of vertical cleaning and rotating brushing of workpiece in cleaning agent. By simulating various working conditions, the cleaning power of the cleaning agent is tested. After cleaning, workpiece 338 is taken out from the cleaning test component 7 and put back into the drying oven 4 for drying. After drying, the cleaned workpiece 338 is put into the weighing unit 5 for weighing, thereby detecting the cleaning power of the cleaning agent.
