Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a cleaning equipment for mechanical design workpieces. Background Technology

[0002] Mechanical design is the process of conceiving, analyzing, and calculating the working principle, structure, motion mode, force and energy transmission mode, material and shape dimensions of each part, lubrication method, etc. of a machine according to the usage requirements, and then transforming it into a specific description as a basis for manufacturing. In the mechanical design process, the workpieces generated during the mechanical design process need to be cleaned, so cleaning equipment is usually required to clean the workpieces.

[0003] An existing mechanical workpiece cleaning device (Announcement No.: CN221017663U) has at least the following drawbacks:

[0004] In the aforementioned patent, the cleaning efficiency can be improved by combining an ultrasonic generator with the flow of cleaning fluid (through the first and second through holes), which is especially suitable for cleaning workpieces with complex shapes. Furthermore, the placement components are detachable, which facilitates the loading and unloading of workpieces. The baffle is locked by a fixing bolt, making the operation relatively simple. However, the workpieces need to be manually removed and dried after cleaning, which increases the number of steps. At the same time, the ultrasonic generator under the shelf may not be able to evenly cover multiple layers of workpieces, making it difficult to guarantee the cleaning effect, which has certain limitations.

[0026] Reference Figures 1-5A mechanical workpiece cleaning device includes a movable frame 1, with several supporting baskets 2 inside the movable frame 1. A PLC controller is fixedly installed on one side of the movable frame 1. A cleaning assembly is also included, used for cleaning the workpieces. The cleaning assembly includes a cleaning chamber 3 inside the movable frame 1. A first support frame 5 is located inside the movable frame 1. A support hole 22 is formed on the top surface of the first support frame 5. A rotating frame 7 is movably fitted onto the inner circular wall of the support hole 22. A second circular through hole is formed on the top surface of the rotating frame 7. A rotating placement frame is movably fitted onto the inner circular wall of the second circular through hole. 4. Several gear disks 6 are movably sleeved inside the rotating frame 7. The rotating placement frame 4 is fixedly sleeved with the gear disks 6. A gear ring 11 is fixedly installed on the bottom surface of the first support frame 5. The tooth groove of the gear ring 11 meshes with the gear disk 6. A drive motor 8 is fixedly installed on the top surface of the first support frame 5. The bottom surface of the drive shaft of the drive motor 8 is fixedly installed with the rotating frame 7. A crane 10 is fixedly installed on the top surface of the moving frame 1. The lifting cable of the crane 10 is fixedly installed with the support frame of the drive motor 8. The rotating placement frame 4 is movably sleeved with the support basket 2. The rinsing assembly is used to rinse the cleaning fluid on the outside of the workpiece.

[0027] In use, when ultrasonic cleaning is required, the operator injects the cleaning solution into the cleaning chamber 3 through the liquid inlet pipe of the movable frame 1, takes out the support basket 2 on the rotating placement frame 4, loads the workpiece into it and reinstalls it in place, then starts the crane 10 to lower the cable, so that the first support frame 5 moves vertically downward under the guidance of the guide rail 9, completely immersing the workpiece in the cleaning solution. The drive motor 8 drives the rotating frame 7 to rotate, and the gear disk 6 meshes with the gear ring 11 to achieve the combined revolution and rotation of the support basket 2. At the same time, the ultrasonic generator is started to drive the vibrating plate 12 to work. The rotational motion makes the ultrasonic waves fully cover the surface of the workpiece, avoiding the omissions and crevices of the workpiece from being cleaned, thus ensuring the cleaning effect of the workpiece. After cleaning, the crane 10 lifts the support basket 2 to remove the workpiece.

[0028] In this embodiment, the rinsing assembly includes: a track frame 23, which is fixedly installed on the bottom surface of the cleaning chamber 3; the pulley of the movable frame 1 is movably connected to the track groove of the track frame 23; a second support frame 13 is fixedly installed on one side of the track frame 23; a spray pipe 14 is detachably sleeved inside the second support frame 13; a water collection chamber 15 is fixedly sleeved inside the track frame 23; a drain pipe 16 is connected through one side of the water collection chamber 15; a fan 17 is fixedly installed on one side of the second support frame 13; and the crane 10, the drive motor 8, and the fan 17 are electrically connected to the PLC controller.

[0029] In use, connect the spray pipe 14 to the water supply line, start the drive motor 8 to keep the support basket 2 rotating, and the operator holds the spray pipe 14 to spray the workpiece from all directions. The rinsing wastewater is collected in the water collection tank 15 and discharged through the drain pipe 16. Turn on the fan 17 to air dry. After drying, the workpiece can be taken out.

[0030] In this embodiment, several vibrating plates 12 are fixedly installed on the bottom and outer sides of the cleaning chamber 3. An ultrasonic generator is fixedly installed on one side of the cleaning chamber 3. The ultrasonic generator is electrically connected to the vibrating plates 12. Specifically, the ultrasonic generator outputs a high-frequency electrical signal, which is transmitted to the vibrating plates 12 through a coaxial cable or shielded cable. The piezoelectric ceramic material of the vibrating plate 12 needs to match the output impedance of the generator to ensure efficient energy transfer. The vibrating plate 12 is designed with a specific resonant frequency (such as 28kHz or 40kHz). When the frequency matches the generator frequency, the mechanical vibration amplitude is the largest. Brief cleaning principle: The mechanical vibration of the vibrating plate 12 forms longitudinal waves (compression waves) in the liquid. Cavitation effect: The ultrasonic negative pressure phase makes the local pressure of the liquid lower than the vapor pressure, generating tiny vacuum bubbles (cavitation nuclei). In the positive pressure phase, the bubbles collapse instantly, releasing high temperature (about 5000K) and high pressure (about 1000atm) shock waves. The shock waves peel off the oil, particles or oxide layer on the surface of the workpiece, especially effective for micropores and gaps. Two guide rails 9 are fixedly installed on both sides of the inside of the moving frame 1. The slider of the guide rail 9 is fixedly installed on one side of the first support frame 5.

[0031] In use, by starting the crane 10 and lowering the cable, the first support frame 5 moves vertically downward under the guidance of the guide rail 9, so that the workpiece is completely immersed in the cleaning solution. The guide rail 9 ensures that the movement trajectory of the first support frame 5 is correct.

[0032] In this embodiment, two fixing plates 18 are fixedly installed on one side of the track frame 23, and a fixing plate 18 is fixedly installed on one side of the movable frame 1. A limiting hole 20 is opened on the top surface of the fixing plate 18, and a plug 19 is movably sleeved on the inner circular wall of the limiting hole 20. Two limiting plates 21 are fixedly installed on one side of the track frame 23, and handles 24 are fixedly installed on both sides of the movable frame 1.

[0033] In use, after cleaning, pull out the plug 19 from the right fixing plate 18, hold the handle 24 and push the moving frame 1 along the track frame 23 to the rinsing station. Insert the plug 19 into the limiting hole 20 on the top surface of the left fixing plate 18 to complete the positioning. The fixing plate 18 and the plug 19 are used to position and fix the moving frame 1, preventing it from moving on its own.

[0034] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0035] When ultrasonic cleaning is required, the operator injects cleaning fluid into the cleaning chamber 3 through the inlet pipe of the movable frame 1, removes the support basket 2 from the rotating placement frame 4, loads the workpiece into it, and reinstalls it in place. Then, the crane 10 is started to lower the cable, causing the first support frame 5 to move vertically downward under the guidance of the guide rail 9, completely immersing the workpiece in the cleaning fluid. It should be noted that in order to improve the cleaning effect, the aperture of the support basket 2 can be as large as possible to reduce the obstruction of ultrasonic waves. At the same time, the placement chamber of the rotating placement frame 4 can be equipped with a blocking device to prevent the support basket 2 from being blocked. When slippage occurs, the diameter of the supporting basket 2 is smaller than that of the rotating placement frame 4, allowing it to be removed. The drive motor 8 drives the rotating frame 7 to rotate, and the gear disk 6 meshes with the gear ring 11 to achieve a combined revolution and rotation motion of the supporting basket 2. Simultaneously, the ultrasonic generator is activated to drive the vibrating plate 12 to work. The side vibrating plate 12 cleans the top and sides of the workpiece (the vibrating plate 12 is located at the same level as the workpiece and slightly above it), while the bottom vibrating plate 12 cleans the bottom of the workpiece. Centrifugal force assists in removing stubborn stains and accelerates the penetration of the cleaning fluid. The dynamic water flow enhances the coverage of the ultrasonic cavitation effect, ensuring that the ultrasonic waves fully cover the surface. The workpiece surface is covered to prevent corners and hard-to-reach areas from being missed, ensuring effective cleaning. After cleaning, the crane 10 lifts the support basket 2 to remove the workpiece. Using the provided bolt 19, the bolt 19 on the right-side fixing plate 18 is pulled out after cleaning. The handle 24 is used to push the moving frame 1 along the track frame 23 to the rinsing station. The bolt 19 is then inserted into the limiting hole 20 on the top surface of the left-side fixing plate 18 for positioning. The spray pipe 14 is connected to the water supply line, and the drive motor 8 is started to keep the support basket 2 rotating. The operator uses the spray pipe 14 to spray the workpiece from all directions. The rinsing wastewater is collected in the collection tank 15 and discharged through the drain pipe 16. The fan 17 is turned on for air drying. After drying, the workpiece can be removed. This design realizes the integrated operation of cleaning, rinsing and drying, which significantly improves the processing efficiency and eliminates the need for manual removal for drying. At the same time, ultrasonic cleaning is performed on the sides and bottom of the workpiece. Combined with the workpiece's rotation and revolution, centrifugal force is used to help remove stubborn stains and accelerate the penetration of cleaning fluid. The dynamic water flow enhances the coverage of the ultrasonic cavitation effect, so that the ultrasonic waves fully cover the surface of the workpiece, avoiding dead corners and ensuring the cleaning effect of the workpiece. It is quite practical.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
