[0002] A hydraulic pump is a mechanical device that transports liquid or pressurizes liquid by utilizing changes in sealed volume. This pump is usually composed of one or more components such as pistons, plungers or blades that can perform reciprocating or rotary motion. These components form a sealed volume in the pump body and achieve liquid suction, discharge and pressurization by changing the size of the sealed volume. Hydraulic pumps play a vital role in various hydraulic systems. They are widely used in engineering machinery, metallurgical equipment, ships, aircraft and many other fields. The existence of hydraulic pumps is an indispensable and important part of hydraulic systems.

The outer tops of the left and right sets of L-shaped vertical guide rods 4210 are slidably connected to the four sides of the fishnet-shaped filter connection frame 417.

[0041] When the hydraulic pump body needs to be cleaned, first place the pump body on the top of the bottom support plate 421 and then start the dual-axis motor 36. The dual-axis motor 36 drives the conical teeth 37 on the left and right sides to rotate. The rotation of the conical teeth 37 drives the second conical teeth 38 engaged therewith to rotate. The rotation of the second conical teeth 38 drives the screw rod 310 to rotate. The rotation of the screw rod 310 drives the transmission rod 311 to rise and fall. The lifting of the transmission rod 311 drives the lifting rod 312 to rise and fall. The lifting of the lifting rod 312 drives the columnar lifting rod 313 to rise and fall. The lifting of the columnar lifting rod 313 drives the bottom frame connecting frame 41 to rise and fall. The lifting of the bottom frame connecting frame 41 drives the bottom bracket 42 to rise and fall. The lifting of the bottom bracket 42 drives the hydraulic pump body to rise and fall, thereby facilitating the lowering of the hydraulic pump body. When the pump body placement rack 4 is pressed by the columnar lifting rod 313 and continues to move toward the bottom of the inner wall of the ultrasonic cleaning tank 2, the four arc-shaped rotating rods 429 at the bottom of the bottom bracket 42 are resisted by the bottom of the inner wall of the ultrasonic cleaning tank 2. Under the action of the resistance force, the four arc-shaped rotating rods 429 are rotated by the resistance force. The four arc-shaped rotating rods 429 rotate with the connection of the four arc-shaped hinge blocks 427 as the axis. The rotation of the four arc-shaped rotating rods 429 causes the pulleys 428 at the bottom of the four columnar rods 422 to slide on the top of the arc-shaped rotating rods 429, thereby pushing the columnar rods 422 to move to the top. The four columnar rods 422 move to the top and drive the bottom support plate 421 and The hydraulic pump body placed on the top thereof moves toward the top and gradually approaches the fishnet filter 418 on the inner wall of the fishnet filter 418, and the hydraulic pump is stabilized in the placement area through the bottom support plate 421 and the fishnet filter 418, so that the cleaning fluid inside the ultrasonic cleaning tank 2 can fully and evenly clean all parts of the hydraulic pump body, and will not be affected by the ultrasonic wave and cause the hydraulic pump body to vibrate violently inside the ultrasonic cleaning tank 2, so that the hydraulic pump body remains stable during the cleaning process, avoiding the risk of damage to the hydraulic pump body caused by violent shaking. In addition, the oil or debris cleaned by the ultrasonically cleaned pump body gradually floats to the surface of the ultrasonic cleaning tank 2. When the ultrasonic cleaning tank 2 placed on the pump body placement rack 4 is cleaned, When the lifting is performed by the lifting mechanism 3, the oil or debris is filtered through the fishing mesh filter 418 connected to the inner wall of the outer frame 417 to prevent the oil or debris from rising with the lifting of the lifting mechanism 3, causing secondary pollution of the oil or debris. At the same time, the setting of the fishing mesh filter 418 also makes it convenient for the staff to collect and clean the oil or debris, thereby improving the practicality of the cleaning device. When the pump body placement rack 4 is gradually lifted, the bottom of the arc-shaped rotating rod 429 gradually separates from the bottom of the inner wall of the ultrasonic cleaning tank 2, and the arc-shaped rotating rod 429 gradually returns to its original position under the reset action of the spring 425, and the columnar upright 422 also rises and falls accordingly, and the bottom support plate 421 and the hydraulic pump body also descend steadily, releasing the positioning of the pump body.

[0042] In addition, the present invention also relates to a cleaning device and method for producing a hydraulic pump body, comprising the following steps:

[0043] Step 1: Place the hydraulic pump body to be cleaned on the bottom support plate 421 to ensure that the pump body is stable and does not shake;

[0044] Step 2: Start the dual-axis motor 36 of the cleaning device. The dual-axis motor 36 drives the conical gear 37 and the subsequent transmission mechanism to realize the lifting and positioning of the pump body in the ultrasonic cleaning tank 2, preparing for the cleaning process;

[0045] Step 3: The ultrasonic cleaning tank 2 starts working, emitting ultrasonic waves to clean the hydraulic pump body comprehensively and evenly, ensuring that all parts of the pump body can be effectively cleaned;

[0046] Step 4: After cleaning is completed, the pump body placement rack 4 and the hydraulic pump body are steadily lifted to the outside of the ultrasonic cleaning tank 2 by the lifting mechanism 3. At this time, the fishnet filter 418 filters the oil or debris to avoid secondary contamination;

[0047] Step 5: The staff can collect and clean the oil or debris on the fishnet filter 418 to keep the cleaning device clean and efficient;

[0048] Step 6: Take out the cleaned hydraulic pump body and proceed to the next production or testing process.

[0049] Working principle of the present invention: When the hydraulic pump body needs to be cleaned, first place the pump body on the top of the bottom support plate 421 and then start the dual-axis motor 36. The dual-axis motor 36 drives the conical teeth 37 on the left and right sides to rotate. The rotation of the conical teeth 37 drives the second conical teeth 38 engaged therewith to rotate. The rotation of the second conical teeth 38 drives the screw rod 310 to rotate. The rotation of the screw rod 310 drives the transmission rod 311 to rise and fall. The lifting of the transmission rod 311 drives the lifting rod 312 to rise and fall. The lifting of the lifting rod 312 drives the columnar lifting rod 313 to rise and fall. The lifting of the columnar lifting rod 313 drives the bottom frame connecting frame 41 to rise and fall. The lifting of the bottom frame connecting frame 41 drives the bottom bracket 42 to rise and fall. The lifting of the frame 42 drives the hydraulic pump body to lift, thereby facilitating the lowering of the hydraulic pump body into the ultrasonic cleaning tank 2 for cleaning. When the pump body placement frame 4 is pressed by the columnar lifting rod 313 and continues to move toward the bottom of the inner wall of the ultrasonic cleaning tank 2, at this time, the four arc-shaped rotating rods 429 at the bottom of the bottom bracket 42 are resisted by the bottom of the inner wall of the ultrasonic cleaning tank 2. Under the action of the resistance force, the four arc-shaped rotating rods 429 are rotated by the resistance force. The four arc-shaped rotating rods 429 rotate with the connection of the four arc-shaped hinge blocks 427 as the axis. The rotation of the four arc-shaped rotating rods 429 causes the pulleys 428 at the bottom of the four columnar rods 422 to slide on the top of the arc-shaped rotating rods 429. Then the columnar upright pole 422 is pushed to move toward the top. The four columnar upright poles 422 move toward the top and drive the bottom support plate 421 and the hydraulic pump body placed on its top to move toward the top and gradually approach the fishnet filter 418 on the inner wall of the fishnet filter 418. The hydraulic pump is stabilized in the placement area through the bottom support plate 421 and the fishnet filter 418. The cleaning fluid inside the ultrasonic cleaning tank 2 cleans all parts of the hydraulic pump body comprehensively and evenly. The oil or debris cleaned by the ultrasonic cleaning of the pump body gradually floats to the surface of the ultrasonic cleaning tank 2. When the ultrasonic cleaning tank 2 placed on the pump body placement rack 4 is cleaned and is lifted by the lifting mechanism 3, the hydraulic pump is moved to the top through the fishnet filter 418. The fishnet-shaped filter 418 connected to the inner wall of the outer frame 417 filters the oil or debris to prevent the oil or debris from rising with the lifting of the lifting mechanism 3, causing secondary pollution of the oil or debris. At the same time, the setting of the fishnet-shaped filter 418 also makes it convenient for the staff to collect and clean the oil or debris, thereby improving the practicality of the cleaning device. When the pump body placement rack 4 is gradually lifted, the bottom of the arc-shaped rotating rod 429 gradually separates from the bottom of the inner wall of the ultrasonic cleaning tank 2, and the arc-shaped rotating rod 429 gradually returns to its original position under the reset action of the spring 425, and the columnar upright 422 also rises and falls accordingly, and the bottom support plate 421 and the hydraulic pump body also descend steadily, releasing the positioning of the pump body.
