[0031] like Figure 4As shown, the vertical end of the feeding block 25 extends into the adjusting block 20 to form an inner retraction cavity 28, and a stabilizing spring 29 is arranged in the inner retraction cavity 28, one end of the stabilizing spring 29 is fixedly connected with the feeding block 25, and the other end of the stabilizing spring 29 is fixedly connected with the inner wall of the inner retraction cavity 28, and the stabilizing spring 29 provides the feeding block 25 with elastic force along the sliding direction of the feeding block 25.

Figure 5

[0033] The finished crankcase is placed into the mounting cavity 11 and clamped and fixed by using the clamping assembly, and then the driving assembly drives the adjusting block 20 to adjust the position of the adjusting block 20 and abuts against the end of the outer side of the crankcase away from the opening of the mounting cavity 11 by using the adjusting assembly, at this time, the flexible sealing strip 37 can be adjusted to the shape conforming to the outer contour of the end of the crankcase away from the opening of the mounting cavity 11 by the adjusting assembly, at this time, the jacking cylinder 17 drives the pressing plate 16 to move towards the crankcase and abut against the feeding block 25, at this time, the pressing plate 16 drives the feeding block 25 to move towards the crankcase and makes the flexible sealing strip 37 on the feeding block 25 abut against and bond with the side end face of the crankcase away from the opening of the mounting cavity 11, and then the pressing plate 16 reversely moves under the driving of the jacking cylinder 17 and is disconnected with the feeding block 25, at this time, the feeding block 25 is disconnected with the flexible sealing strip 37 under the action of gravity, the driving assembly drives the adjusting block 20 and the feeding block 25 to move away from the crankcase, and then the jacking cylinder 17 is started again to make the pressing plate 16 press and combine with the flexible sealing strip 37, at this time, the flexible sealing strip 37 can fill the abutment gap between the end face of the crankcase and the pressing plate 16, at this time, the cleaning liquid is poured into the inside of the crankcase by using the external water supply device and the liquid inside the crankcase is disturbed by using the artificial stirring device, so that the cleaning liquid can fully clean the inside of the crankcase, because there is a gap between the adjusting blocks 20 located at the four sides of the crankcase, therefore, there is still a part of space on the abutment face of the pressing plate 16 and the crankcase without the filling of the flexible sealing strip 37, therefore, the liquid in the crankcase will be discharged through this part of the gap, so as to achieve the purpose of discharging the debris in the crankcase along with the liquid, but the cleaning liquid can still remain in the crankcase for a long time, so as to avoid the waste of the cleaning liquid, and the purpose of cleaning the crankcase is achieved while the waste of the cleaning liquid is reduced, and the contour of the flexible sealing strip 37 can be adjusted to conform to the crankcases with different outer contours by the adjusting of the adjusting assembly, so as to greatly improve the adaptable range of the device.

[0034] ​When the driving motor 14 is started, the driving motor 14 drives the driving screw rod 24 to rotate, and the connecting plate 22 can slide along the driving cavity 23 towards or away from the crankcase due to the threaded connection relationship between the driving screw rod 24 and the connecting plate 22, so as to adjust the position of the adjusting block 20, and the clamping cylinder 42 is started to drive the clamping block 43 to move towards the crankcase to make the clamping block 43 abut against the crankcase to form a holding, so as to maintain the stability of the crankcase during cleaning, and will not affect the internal structure of the crankcase, so that the internal cleaning of the crankcase can be smoothly carried out.

[0035] When the driving assembly drives the adjusting block 20 to move towards the crankcase, the end of the jacking rod 21 will first abut against the outer side of the crankcase (i.e. the outer side of the flange 12 connecting the crankcase and the oil pan), and since the profile of the outer side of the crankcase is not a pure straight rectangular structure, at this time the ends of the jacking rods 21 abut against the outer side of the crankcase and the position changes along the outer profile of the crankcase, and the path of the line connecting the ends of the jacking rods 21 towards the crankcase is similar to the outer profile of the crankcase, and the jacking rods 21 are compressed in the changing process, and the jacking rods 21 are in a free state when the pressure springs 27 are not abutted against the crankcase, and the ends are flush with each other for next use. When the position of the jacking rod 21 changes, the jacking rod 21 drives the position of the connecting rod 30 to change, and the sliding block 33 is always abutted against the end of the connecting rod 30 away from the jacking rod 21 due to the elastic action of the return spring 32, at this time the position of the sliding block 33 changes along with the position change of the connecting rod 30 under the elastic action of the return spring 32, so that the position of the flexible sealing strip 37 connected with the sliding block 33 changes, and in the changing process of the extension path of the flexible sealing strip 37, the limiting block 35 limits the flexible sealing strip 37 in the horizontal direction to avoid the flexible sealing strip 37 from separating from the sliding block 33, so as to achieve the purpose that the extension path of the flexible sealing strip 37 matches the outer profile of the crankcase. When all the jacking rods 21 stop moving, the extension path of the flexible sealing strip 37 is similar to the outer profile of the flange 12 of the crankcase at this time, and after the above process makes the pressing plate 16 abut against the crankcase, the flexible sealing strip 37 follows the profile of the flange 12 of the crankcase to fill the gap between the crankcase and the pressing plate 16, so as to avoid the rapid leakage of the cleaning liquid in the crankcase.

[0036] When the outer contour of the crankcase flange 12 changes, the path of the flexible sealing strip 37 can also be changed through the above process, so that the device can adapt to different outer contour crankcases. Then the pressing plate 16 presses the material releasing block 25 towards the crankcase, and the flexible sealing strip 37 is bonded to the crankcase. In the process of bonding the flexible sealing strip 37 to the crankcase, the limiting block 35 is pressed into the limiting cavity 34 by the crankcase for storage, so as to avoid the length of the limiting block 35 extending to one end outside the limiting cavity 34 being too long to affect the bonding of the flexible sealing strip 37. In the process of moving the material releasing block 25 towards the crankcase, the connecting rod 30 is pushed to move away from the material releasing block 25, and at this time the connecting rod 30 and the top rod 21 slide relative to each other.

[0037] The material releasing block 25 can be kept stable in a free state under the elastic action of the stabilizing spring 29, and in the process of moving the material releasing block 25 by the pressing plate 16, the material releasing block 25 can move inwardly into the cavity 28 and compress the stabilizing spring 29, so that the flexible sealing strip 37 can be extruded with the end face of the crankcase and bonded to the end face of the crankcase. When the material releasing block 25 is disconnected from the pressing plate 16, the material releasing block 25 is reset under the elastic action of the stabilizing spring 29 to perform the next round of flexible sealing strip 37 fitting and installation, without the need for secondary adjustment of the position of the material releasing block 25, greatly reducing the manual operation steps and reducing the labor intensity of the user.

[0038] After the cleaning liquid is poured into the crankcase, the sealing cover plate 40 is used to close the opening of the mounting cavity 11, and at this time the stirring shaft 41 extends into the crankcase. Under the driving of the driving element, the stirring shaft 41 rotates to disturb the cleaning liquid and clean the inside of the crankcase, without the need for manual disturbance by the above-mentioned tool, and the closed mounting cavity 11 can avoid splashing of the cleaning liquid during disturbance and falling of external foreign matters into the cleaning range, which is beneficial to improve the cleaning quality of the crankcase. And when a small amount of cleaning liquid is used, the inside of the crankcase can also be fully cleaned. Compared with the traditional cleaning method of not plugging the opening of the crankcase and using a large amount of cleaning liquid for flushing, the use amount of cleaning liquid can be greatly reduced, which is beneficial to reduce the production cost of the crankcase.

[0039] The basic principles, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and various changes and improvements can be made without departing from the spirit and scope of the present application. These changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
