[0039] Example

[0040] During the processing of metal castings, some stains are often attached to their outer walls. In order to improve the quality of the products, metal castings are often cleaned. Among them, ultrasonic cleaning is one of the commonly used cleaning methods. It uses the cavitation effect, acceleration effect and straight flow effect of ultrasonic waves in liquids to directly and indirectly affect liquids and dirt to achieve the purpose of cleaning. When ultrasonic cleaning is used, the position of the metal casting is generally fixed, which causes part of the casting to be in contact with the inner wall of the ultrasonic cleaning device. For this part, there is often a cleaning dead angle, which affects the subsequent cleaning quality and the product quality. In order to solve the above technical problems, this embodiment provides the following technical solutions:

[0041] For details, see Figure 1-4 , this embodiment provides a metal casting cleaning device, including a workbench 60, on which a liquid storage tank 10, an ultrasonic cleaning box 20 and a drying box 30 are sequentially arranged along a first direction;

[0042] Furthermore, a material moving mechanism is also provided on the workbench 60, and the material moving mechanism includes a gantry 41, a sliding block 42, a linear driving member, a lifting driving member 44, a fixed block 45, a mounting frame 46, a loading tray 47 and a rotating driving member; the gantry 41 is provided on the workbench 60, the sliding block 42 is slidably provided on the gantry 41 along a first direction, the linear driving member is provided on the gantry 41 and is suitable for driving the sliding block 42 to move along the first direction, the lifting driving member 44 is fixedly connected to the sliding block 42, the fixed block 45 is provided at the driving end of the lifting driving member 44, the mounting frame 46 is fixedly connected to the fixed block 45, the loading tray 47 is rotatably provided at one end of the mounting frame 46 away from the fixed block 45, the rotating driving member is provided on the fixed block 45 and is suitable for driving the loading tray 47 to rotate, and the loading tray 47 is used for loading workpieces;

[0043] Furthermore, a plurality of through holes 476 are formed on the outer wall of the loading tray 47;

[0044] In the above scheme, the loading tray 47 is used to load the workpiece. After the workpiece is loaded, the lifting drive 44 drives the fixed block 45 to rise and fall, the mounting frame 46 is connected to the fixed block 45, and the loading tray 47 is rotatably connected to the mounting frame 46, so it can follow the decline, and the loading tray 47 enters the ultrasonic cleaning box 20. Since a plurality of through holes 476 are provided on the loading tray 47, the liquid medium in the ultrasonic cleaning box 20 can enter the loading tray 47, and the workpiece is cleaned by the action of ultrasonic waves; after cleaning for a period of time, the rotating drive can drive the loading tray 47 to rotate. At this time, the workpiece in the loading tray 47 will produce a certain position change, so that different positions are exposed to the liquid medium, so that this part of the cleaning dead corner can be cleaned; after cleaning, the lifting drive 44 drives the loading tray 47 to rise again The linear drive member drives the sliding block 42 to move along the first direction to drive the loading tray 47 to approach the drying box 30 along the first direction. After reaching the specified position, the lifting drive member 44 drives the loading tray 47 to move down again to dry the workpiece in the drying box 30. During the drying process, the rotary drive member can also drive the loading tray 47 to rotate, so that different positions of the workpiece can be exposed to hot air, thereby improving the drying efficiency; this solution can adjust the position of the workpiece through the rotary drive member in conjunction with the loading tray 47, thereby effectively reducing the generation of cleaning dead corners during ultrasonic cleaning, improving the cleaning quality, and thereby improving the product quality; in addition, this solution further dries the cleaned workpiece quickly, and the drying efficiency can be further improved by cooperating with the rotary drive member to drive the loading tray 47 to rotate.

[0045] In some of the embodiments, the lifting drive member 44 may be a driving mechanism such as a driving cylinder that can achieve linear drive.

[0046] For details, see Figure 4 The loading tray 47 includes a tray body 471, on which a plurality of loading spaces are separated, and a cover plate 474 is hingedly connected to the tray body 471 at a position corresponding to each loading space, and one end of the cover plate 474 away from the hinge is suitable for being locked to the tray body 471 by a locking screw 475;

[0047] In the above scheme, the staff removes the locking screw 475, and the covering plate 474 can be rotated around the disk body 471 to open. The staff puts the workpiece into the corresponding re-material space and then flips the covering plate 474 to fit the disk body 471, and then installs the locking screw 475 to fix the covering plate 474 on the disk body 471 to close it.

[0048] It is understandable that a plurality of locking screws 475 may be provided; it is further understandable that corresponding threaded holes are provided on the cover plate 474 and the disk body 471 .

[0049] Specifically, a rotating shaft 472 is provided at the axis of the disk body 471 , and the rotating shaft 472 passes through the mounting frame 46 and is rotatably connected to the mounting frame 46 .

[0050] For details, see Figure 3 , the rotating driving member includes a rotating motor 48, a driving shaft 481, a first rotating wheel 482, a second rotating wheel 473 and a transmission belt (not shown in the figure);

[0051] Furthermore, the rotating motor 48 is arranged on the fixed block 45, the driving shaft 481 is arranged at the driving end of the rotating motor 48 and penetrates the mounting frame 46, the first rotating wheel 482 is coaxially arranged with the driving shaft 481, the second rotating wheel 473 is coaxially arranged with the rotating shaft 472, and the transmission belt is sleeved on the first rotating wheel 482 and the second rotating wheel;

[0052] The rotary motor 48 is adapted to drive the first rotating wheel to rotate so as to drive the second rotating wheel 473 to rotate through the transmission belt;

[0053] In the above scheme, the rotating motor 48 drives the driving shaft 481 to rotate and then drives the first rotating wheel 482 to rotate. The first rotating wheel 482 and the second rotating wheel 473 are driven by a transmission belt. Therefore, when the first rotating wheel 482 rotates, it can drive the second rotating wheel 473 to rotate. The rotation of the second rotating wheel 473 drives the rotating shaft 472 to rotate, and then drives the loading plate 47 to rotate.

[0054] In other embodiments, the first rotating wheel 482 and the second rotating wheel 473 may be sprocket wheels, and the transmission belt may be a chain belt meshed with the sprocket wheels.

[0055] Specifically, the ultrasonic cleaning box includes a first box body and an ultrasonic generator 21 disposed in the first box body;

[0056] In the above solution, the ultrasonic generator 21 can emit ultrasonic waves and act on the workpiece through the liquid medium to achieve cleaning of the workpiece.

[0057] Specifically, the liquid storage tank 10 includes a second box body and a plurality of filter screens 11 disposed in the second box body. The second box body is provided with a second liquid inlet 12 and a second liquid outlet 13. The second liquid inlet 12 is higher than the filter screen 11, and the second liquid outlet 13 is lower than the filter screen 11.

[0058] Furthermore, a first liquid inlet 24 and a first liquid outlet 23 are provided on the first box body, the first liquid outlet 23 is connected to a first delivery pipeline 51, and the first delivery pipeline 51 is connected to the second liquid inlet 12; the liquid in the first delivery pipeline 51 is driven by a first pump body 52;

[0059] Furthermore, a second delivery pipeline 53 is provided between the second liquid outlet 13 and the first liquid inlet 24, and the liquid in the second delivery pipeline 53 is driven by a second pump body 54;

[0060] In the above scheme, the liquid located in the first box can be introduced into the second box through the first delivery pipe 51, and the first pump body 52 provides driving force. The liquid located in the first box enters the second box from the second feed port and is filtered by the filter net 11. The filtered liquid enters the bottom of the filter net 11 and is then discharged through the second liquid outlet 13. Driven by the second pump body 54, the liquid enters the first box again through the second delivery pipe 53, thereby replenishing the liquid in the first box.

[0061] The first pump body 52 and the second pump body 54 may be water pumps.

[0062] It is understandable that during the continuous cleaning process, the liquid medium in the first box will gradually decrease. In order to replenish the liquid in the first box in time, this embodiment provides the following technical solutions:

[0063] For details, see Figure 2 , a liquid level sensor 22 is provided in the first box body;

[0064] In the above solution, the liquid level sensor 22 can timely sense the liquid level in the first tank, and when the liquid level drops to a certain height, the staff can be notified to make corresponding adjustments.

[0065] It is understandable that the inner shell of the second tank stores more liquid for supplementing the liquid in the first tank.

[0066] Specifically, the drying box 30 includes a third box body, and a plurality of hot air outlet mechanisms 31 are provided on the inner wall of the third box body;

[0067] In the above scheme, the hot air outlet mechanism 31 can blow out hot air, which can improve the air problem and flow rate on the workpiece, thereby accelerating the evaporation of moisture on the workpiece, improving the drying efficiency of the workpiece, and improving work efficiency.

[0068] It should be noted that the hot air outlet mechanism 31 is a relatively mature technology in the prior art, so this application will not further elaborate on its details and working principle.

[0069] For details, see Figure 1-2 The linear drive member includes a driving motor 433, a screw rod 432 and a rotating seat 431; the screw rod 432 is axially parallel to the first direction and one end of the screw rod 432 is connected to the driving end of the driving motor 433, and the other end is rotatably connected to the rotating seat 431;

[0070] Furthermore, the screw rod 432 is disposed through the sliding block 42 and is threadedly matched with the sliding block 42. The driving motor 433 is adapted to drive the sliding block 42 to move along the first direction by driving the screw rod 432 to rotate.

[0071] In the above solution, the driving motor 433 drives the screw rod 432 to rotate, and the screw rod 432 is threadedly matched with the sliding block 42. Therefore, when the screw rod 432 rotates, the sliding block 42 will move along the axial direction of the screw rod 432, thereby driving the loading tray 47 to move.

[0072] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
