Technical Field
[0001] This utility model relates to the field of cleaning technology for die-cast aluminum alloy parts, and in particular to a cleaning device for die-cast aluminum alloy parts. Background Technology
[0002] Die-cast aluminum alloy cleaning equipment is mainly used to clean oil, impurities, residues, and various chemical substances generated during the production process from the surface of die-cast aluminum alloy parts. In aluminum alloy die-casting production, after casting and cooling, many impurities often adhere to the surface of the parts. These impurities can affect subsequent processing, coating, and quality control. Therefore, cleaning is one of the key steps to ensure that aluminum alloy die-cast parts meet standard quality requirements.
[0003] Existing technologies, such as the utility model patent with publication number CN222447385U, disclose a continuous cleaning device for die-cast aluminum alloy parts. This patent includes a main board and a support. A brushing assembly is mounted on the outer wall of the main board, and a water tank and a rinsing head are mounted on the outer wall of the support. The brushing assembly includes a positioning plate mounted on the outer wall of the main board, a hydraulic rod mounted on the outer wall of the positioning plate, a movable plate fixedly connected to one end of the hydraulic rod, and several electric motors mounted on the outer wall of the movable plate. The output shafts of the electric motors are fixedly connected to cleaning brushes via couplings. This continuous cleaning device for die-cast aluminum alloy parts, through the brushing assembly, allows the cleaning brushes to be rotated by starting and controlling the electric motors during use, performing an initial cleaning of the outer wall of the die-cast aluminum alloy parts. Then, in conjunction with the rinsing head and water tank, the rinsing head further rinses the outer wall of the die-cast aluminum alloy parts, improving the cleaning effect and enhancing the device's usability, thus providing convenience for the user.
[0004] During the operation of cleaning equipment for die-cast aluminum alloy parts, problems may arise due to the complex structure of the workpiece and the presence of blind holes and deep cavities on the surface. Traditional fixed spraying methods cannot effectively cover all surfaces with cleaning fluid, and static or unidirectional cleaning methods are difficult to remove firmly adhered dirt. This results in uneven cleaning effects, dead corners, and low cleaning efficiency. For mass production, this leads to poor product quality consistency and requires a large amount of manual rework. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the existing technology where, due to the complex structure of the workpiece and the presence of blind holes and deep cavities on the surface, the traditional fixed spraying method cannot effectively cover all surfaces with cleaning fluid, and the static or unidirectional cleaning method is difficult to remove firmly adhered dirt. This leads to uneven cleaning effect, dead corners, and low cleaning efficiency. For mass production, this results in poor product quality consistency and requires a lot of manual rework.
[0006] To solve the above technical problems, this utility model provides a cleaning device for die-cast aluminum alloy parts, including: a cleaning frame and a water tank. An electrical control cabinet is installed on one side of the cleaning frame, and a water pump is installed on one side of the cleaning frame. The input end of the water pump is fixedly connected to one side of the bottom of the water tank, and the output end of the water pump is fixedly connected to a spray pipe. The spray pipe is installed on the inner wall surface of the cleaning frame. A support frame is provided inside the cleaning frame, and the position of the support frame corresponds to the position of the spray pipe. Several processed parts are arranged inside the support frame. Adjustment devices are provided on the surfaces of the cleaning frame and the support frame. The adjustment device includes four adjusting rods, one end of each of the four adjusting rods being fixedly connected to the side wall surface of the support frame. The four adjusting rods are arranged in pairs, and each pair... The arc surface of the adjusting rod slides through the side wall surface of the cleaning frame. A spring is fitted onto the arc surface of the adjusting rod, and the two ends of the spring are fixedly connected to the support frame and the cleaning frame, respectively. A connecting plate is fixedly connected to the surface of one set of the adjusting rods, and a top ball is fixedly connected to the surface of the connecting plate. A servo motor is fixedly connected to the side wall surface of the cleaning frame, and an eccentric block is fixedly connected to the output end of the servo motor. One end of the eccentric block abuts against the arc surface of the top ball. When the axis of the top ball coincides with the axis of the eccentric block, the top ball is always on the side of the eccentric block closer to the cleaning frame. An adjusting hole is opened on the bottom surface of the inner wall of the support frame. The cross-section of the adjusting hole is vertical. A rotating disk is slidably connected to the inner wall of the adjusting hole, and the workpiece is located at the upper end of the rotating disk.
[0007] The aforementioned components achieve the following effects: The adjustment device induces high-frequency vibration in the carrier frame during the cleaning process. When the servo motor drives the eccentric block to rotate, the eccentric block periodically pushes the top ball. Due to the spring's reset action, the carrier frame vibrates up and down or left and right, thereby causing the workpiece to vibrate. This vibration mode effectively avoids cleaning dead zones, allowing the cleaning fluid to more thoroughly impact the workpiece surface and remove oil, debris, and other impurities from the die-cast aluminum alloy parts. Simultaneously, the rotating disk, located within the carrier frame, can slide within the adjustment hole, allowing the workpiece to rotate during vibration, further promoting cleaning uniformity. The overall structure improves cleaning efficiency and quality, reduces manual intervention, and is suitable for mass production.
[0008] Preferably, a toothed ring is fixedly connected to the arc surface of the rotating disk, and a toothed rack is fixedly connected to one side of the cleaning frame. The surface of the toothed rack slides through the surface of one side of the support frame, and the toothed surface of the rack meshes with the toothed surface of the toothed ring.
[0009] The aforementioned components achieve the following effect: through the meshing transmission of the gear ring and rack, when the support frame moves up and down during vibration, the rack fixed to the cleaning frame drives the gear ring to rotate, thereby causing the rotating disk and the workpiece on it to rotate automatically. This allows the workpiece to be exposed to the spray water flow from multiple directions during cleaning, enhancing the coverage and uniformity of the cleaning process. It is particularly suitable for die-cast aluminum alloy parts with complex shapes, ensuring that all surfaces are thoroughly cleaned.
[0010] Preferably, the surface of the support frame is provided with a plurality of seepage holes, and the plurality of seepage holes are evenly distributed on the surface of the support frame.
[0011] The aforementioned components achieve the following effects: the drainage holes on the surface of the support frame allow the cleaning fluid to drain quickly, preventing water accumulation that could lead to secondary contamination or cleaning fluid residue. The evenly distributed drainage holes also promote the circulation and filtration of the cleaning fluid, improving fluid utilization while reducing the weight and resistance of the support frame. This helps the vibration device operate more efficiently, maintaining the stability and economy of the cleaning process.
[0012] Preferably, the top bead is a cemented carbide bead, and the cross-sectional dimensions of the top bead are adapted to the cross-sectional dimensions of the eccentric block.
[0013] The aforementioned components achieve the following effects: the top ball is made of hard alloy, possessing high hardness and wear resistance, capable of withstanding frequent impacts from the eccentric block, thus extending the service life of the adjustment device. The top ball's cross-sectional dimensions are matched with the eccentric block, ensuring the accuracy and stability of power transmission and reducing energy loss and noise.
[0014] Preferably, an auxiliary device is provided on the upper surface of the rotating disk corresponding to the position of the workpiece. The auxiliary device includes four support rods, the bottom ends of which are fixedly connected to the surface of the rotating disk. Several moving rings slide through the arc surface of the support rods, and a pressing rod is threaded through the arc surface of each moving ring. One end of the pressing rod abuts against the arc surface of the support rod. A fixing block is fixedly connected to one side surface of the moving ring. The cross-section of the fixing block is "L"-shaped, and the bottom surface of the inner wall of the fixing frame abuts against the surface of the workpiece.
[0015] The aforementioned components achieve the following effects: the auxiliary device, through its support rod, moving ring, pressing rod, and fixing block, provides an adjustable workpiece fixing method. The moving ring can slide along the support rod and is locked by the pressing rod, thus accommodating workpieces of different sizes. The "L"-shaped design of the fixing block reliably supports the bottom of the workpiece, preventing it from shifting or falling during vibration and rotation, ensuring the stability and safety of the cleaning process, while also facilitating quick loading and unloading of workpieces and improving production efficiency.
[0016] Preferably, a limiting rod is threaded through one side surface of the fixing frame, and the limiting rod is a stainless steel rod.
[0017] The aforementioned components achieve the following effects: the limiting rod, made of stainless steel, passes through the fixing frame via threads and can be manually adjusted to press against the side wall of the workpiece. Stainless steel is corrosion-resistant, suitable for humid cleaning environments, and extends the component's lifespan. The limiting rod further enhances the workpiece's fixation, preventing it from shaking during vibration, ensuring uniform cleaning, and avoiding collision damage.
[0018] Preferably, a protective pad is fixedly connected to one end of the limiting rod near the workpiece, the surface of the protective pad abutting against the side wall surface of the workpiece, and the protective pad is a rubber pad.
[0019] The aforementioned components achieve the following effects: the protective pad, a rubber pad, is attached to the end of the limiting rod and makes direct contact with the side wall of the workpiece. The softness of the rubber avoids hard metal-to-metal contact, effectively preventing scratches or indentations on the surface of the die-cast aluminum alloy parts and maintaining the surface quality of the workpiece. Simultaneously, the protective pad increases friction, making the fixation more secure and improving the reliability of the cleaning process and the protection of the workpiece.
[0020] Compared with related technologies, the cleaning equipment for die-cast aluminum alloy parts provided by this utility model has the following beneficial effects: This invention provides a cleaning device for die-cast aluminum alloy parts. Through the operation of the adjustment device, it achieves efficient and automated vibration cleaning of the support frame and workpiece. A servo motor drives the eccentric block to rotate, and through the cooperation of the top ball and spring, the rotational motion is converted into continuous and stable high-frequency micro-amplitude vibration of the support frame. This vibration not only effectively shakes off strongly adhered oil and debris from the workpiece surface, but more importantly, combined with spray rinsing, it causes a violent relative motion between the workpiece and the cleaning fluid, greatly enhancing the rinsing and peeling effect of the cleaning fluid. Simultaneously, the vibration of the support frame is automatically converted into the periodic rotation of the rotating disk through the meshing of the toothed ring and the fixed rack, thus realizing a composite motion of "vibration" and "rotation".
[0021] By operating the auxiliary device, the goal of quickly, flexibly, and reliably fixing workpieces of different sizes and shapes is achieved. The design of the support rod and moving ring allows for flexible adjustment of the height and position of the fixing block, which is then locked in place by the clamping rod, enabling the device to adapt to workpieces of various specifications. The "L"-shaped structure of the fixing block provides stable bottom support for the workpiece, while the limiting rod with rubber protective pads provides flexible clamping to the workpiece from the side. This fixing method ensures that the workpiece will not shift, jump, or collide with each other during severe vibration and rotation, guaranteeing the stability and safety of the cleaning process.

[0027] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The adjusting device 4 includes four adjusting rods 403. One end of each adjusting rod 403 is fixedly connected to the side wall surface of the support frame 8. The four adjusting rods 403 are arranged in pairs.

A servo motor 401 is fixedly connected to the side wall surface of the cleaning frame 1. An eccentric block 402 is fixedly connected to the output end of the servo motor 401. One end of the eccentric block 402 abuts against the arc surface of the top bead 405. The axis of the top bead 405 coincides with the axis of the eccentric block 402. When the top bead 405 is in place, it is always positioned on the side of the eccentric block 402 closest to the cleaning frame 1. An adjustment hole 408 is provided on the bottom surface of the inner wall of the support frame. The cross-section of the adjustment hole 408 is vertical. A rotating disk 409 is slidably connected to the inner wall of the adjustment hole 408. The workpiece 6 is located at the upper end of the rotating disk 409. A toothed ring 410 is fixedly connected to the arc surface of the rotating disk 409. A rack 407 is fixedly connected to one side of the cleaning frame 1. The surface of the rack 407 slides through the surface of one side of the support frame 8. The tooth surface of the rack 407 meshes with the tooth surface of the toothed ring 410. Several seepage holes 411 are provided on the surface of the support frame 8. Several seepage holes 411 are evenly distributed on the surface of the support frame 8. The top bead 405 is a hard alloy bead. The cross-sectional dimensions of the top bead 405 are adapted to the cross-sectional dimensions of the eccentric block 402. In the embodiments of this utility model, please refer to Figure 4 The auxiliary device 5 includes four support rods 51. The bottom ends of the four support rods 51 are fixedly connected to the surface of the rotating disk 409. Several moving rings 52 slide through the arc surface of the support rods 51. A pressing rod 53 is threaded through the arc surface of the moving rings 52. One end of the pressing rod 53 abuts against the arc surface of the support rod 51. A fixing block 54 is fixedly connected to one side surface of the moving rings 52. The cross-section of the fixing block 54 is "L". The bottom surface of the inner wall of the fixing frame abuts against the surface of the workpiece 6. A limiting rod 55 is threaded through one side surface of the fixing frame. The limiting rod 55 is a stainless steel rod. A protective pad 56 is fixedly connected to one end of the limiting rod 55 near the workpiece 6. The surface of the protective pad 56 abuts against the side wall surface of the workpiece 6. The protective pad 56 is a rubber pad. The working principle of the die-cast aluminum alloy cleaning equipment provided by this utility model is as follows: The operator places the die-cast aluminum alloy workpiece 6 to be cleaned on the rotating disk 409 and uses the auxiliary device 5, namely the adjustable fixing block 54 and the limiting rod 55 with protective pad 56, to securely fix it to prevent displacement or collision during subsequent cleaning. The equipment is started through the electrical control cabinet 2. The servo motor 401 starts working, driving the eccentric block 402 on its output shaft to rotate. During the rotation of the eccentric block 402, its protruding part periodically abuts against and pushes the top ball 405 connected to the support frame 8, overcoming the elastic force of the spring 404, causing the entire support frame 8 to generate a displacement along the direction of the adjusting rod 403. When the protruding part of the eccentric block 402 rotates past the top ball 405, the support frame 8 quickly returns to its original position under the action of the restoring force of the spring 404. This cycle repeats, and the servo motor 401 continues to rotate, thereby causing the support frame 8 and the internal workpiece 6 to generate continuous, high-frequency micro-amplitude vibrations. This vibration effectively shakes off firmly adhering debris and dirt from the workpiece surface and causes the workpiece and cleaning fluid to move violently relative to each other. Simultaneously, the water pump 3 draws cleaning fluid from the water tank 7 and sprays it onto the vibrating workpiece 6 through the spray pipe 9 at a certain pressure. The water flow impact combined with vibration penetrates deep into the complex structure and crevices of the workpiece surface, achieving initial rinsing and fine cleaning. Meanwhile, driven by the adjusting device 4, the entire support frame 8 reciprocates vertically. The rack 407, fixedly mounted on the cleaning frame 1, remains stationary. When the support frame 8 moves up and down, the gear ring 410, which meshes with the rack 407, is driven, thereby causing the rotating disk 409 below and the workpiece 6 fixed on it to rotate around the axis. The combination of vibration, spraying, and rotation creates a three-dimensional, dynamic cleaning environment, ensuring that all surfaces and blind holes of the workpiece are fully covered and rinsed by the cleaning fluid, leaving no dead corners and greatly improving the uniformity and thoroughness of cleaning. The water used and the dirt that falls off during the cleaning process flow out into the cleaning frame 1 through the evenly distributed seepage holes 411 on the surface of the support frame 8. After the cleaning process is completed, the servo motor 401 and the water pump 3 stop working. Vibration and rotation stop, and spraying ends. The operator can open the equipment and take out the cleaned workpiece 6. The entire cleaning process is highly automated, efficient, and provides good protection for the surface of the workpiece.
