Technical Field

[0001] The present invention relates to the technical field of environmental protection cleaning, and particularly to a hydraulic component cleaning device. Background Art

[0002] Sound wave cleaning machines are widely used in the cleaning of hydraulic components. However, due to the presence of a large number of micro-holes and blind holes in hydraulic components, it is difficult for the cleaning liquid to completely enter them under normal pressure. It is necessary to generate negative pressure by means of vacuum pumping to discharge the residual gas in the above holes.

[0003] For example, patent application number: CN202510159777.0, discloses an ultrasonic cleaning machine, which further includes: a flushing mechanism for flushing parts. The flushing mechanism is arranged inside the cleaning machine. The flushing mechanism includes a steady flow plate and a connecting plate. A fixed pipe is fixedly connected to the top of the connecting plate. A rotating pipe is arranged outside the fixed pipe. A flared pipe is fixedly connected to the bottom of the rotating pipe. The connecting plate is fixedly connected inside the cleaning machine; by placing the parts in a hemispherical frame and controlling the position of the hemispherical frame to control the cleaning of the parts and the situation of entering and leaving the cleaning machine, the purpose of improving the use efficiency of the equipment is achieved;

[0004] Currently, the method of vacuum pumping generally uses a vacuum pump to pump out the air in the sealed cleaning tank, which has problems such as slow pumping speed, high noise, and high energy consumption; the existing technology can no longer meet the needs of people at the present stage. Based on the current situation, it is urgent to improve the existing technology. Summary of the Invention

When the cover plate is closed, the bolt assembly is internally connected to the locking pressing plate, and the tightness of the bolt assembly and the locking pressing plate is adjusted to make the seal between the cover plate and the water tank stronger.

[0010] The bolt assembly can rotate. By rotating the bolt assembly clockwise, the pressure between the cover plate and the water tank can be increased, so that the seal between the cover plate and the water tank is stronger.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art within the scope of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Refer to Figure 1 , the present invention provides the following technical solution: a hydraulic component cleaning device, including: a cleaning machine main body 100, a bolt assembly 101, a sealing rubber strip 102, a water tank 103, a diversion groove 104, a locking seat 105, a liquid discharge port 106, a U-shaped fixing buckle 107, a cover plate 200, a one-way valve 201, a pressure sensor 202, a locking pressing plate 203, a cover plate support 204, a cylinder barrel 300, a piston chamber 301, a piston 302, a first sealing ring 303, a second sealing ring 304, a first fixing component 305, a third sealing ring 306, a cylinder 400, a second fixing component 401;

[0023] Refer to Figure 4 , a water tank 103 is provided at the upper end of the cleaning machine main body 100, and a sealing rubber strip 102 is provided at the opening of the upper end of the water tank 103. A diversion groove 104 is provided outside the water tank 103, and a liquid discharge port 106 is provided outward at the included angle of the diversion groove 104, and the liquid discharge port 106 is externally connected to a liquid storage tank; at the middle position of the upper ends of three sides of the outside of the cleaning machine main body 100, locking seats 105 are provided, and the locking seats 105 are fixedly connected to the bolt assembly 101 upward; at the upper end of the remaining side of the outside of the cleaning machine main body 100, a U-shaped fixing buckle 107 is provided, and the U-shaped fixing buckle 107 is externally connected to the cover plate support 204 in a transmission manner, and the cover plate support 204 is fixedly connected to one end of the cover plate 200; at the middle position of the other three ends of the cover plate 200, locking pressing plates 203 are provided.

[0024] Refer to Figure 1 and Figure 2, in this embodiment, the cover plate 200 is drivingly connected to the cover plate bracket 204. The cover plate 200 opens and closes as the cover plate bracket 204 rotates. When the cover plate 200 is closed, the bolt assembly 101 is embeddedly connected to the locking pressure plate 203, and the tightness between the bolt assembly 101 and the locking pressure plate 203 is adjusted to make the seal between the cover plate 200 and the water tank 103 stronger. In this embodiment, the bolt assembly 101 can rotate. By rotating the bolt assembly 101 clockwise, the pressure between the cover plate 200 and the water tank 103 can be increased, thereby making the seal between the cover plate 200 and the water tank 103 stronger;

[0025] One side of the upper plate surface of the cover plate 200 is provided with a one-way valve 201, and the other side of the upper plate surface of the cover plate 200 is provided with a pressure sensor 202, and the pressure sensor 202 is externally connected to a PLC (programmable logic controller);

[0026] Reference Figure 3 , a cylinder 300 is provided upward at the center of the upper side of the cover plate 200, and a second sealing ring 304 is provided between the cover plate 200 and the cylinder 300. The cover plate 200 and the cylinder 300 are fixedly connected by a first fixing assembly 305. A piston chamber 301 is provided inside the cylinder 300, and a piston 302 is provided in the piston chamber 301. A first sealing ring 303 is provided between the piston chamber 301 and the piston 302. The upper end of the cylinder 300 is fixedly connected upward to a cylinder 400. The cylinder 300 and the cylinder 400 are fixedly connected by a second fixing assembly 401, and a third sealing ring 306 is provided between the cylinder 300 and the cylinder 400. The bottom of the cylinder 400 is embedded into the piston chamber 301 and is drivingly connected to the piston 302.

[0027] Reference Figure 1, in this embodiment, during operation, the workpiece to be cleaned is placed in the water tank 103, and the cleaning liquid is injected into the water tank 103 until it overflows. The overflowing cleaning liquid flows back to the outer liquid storage tank through the diversion groove 104 and the drain port 106 in sequence. The air cylinder 400 pushes the piston 302 out of the piston chamber 301. After the end face of the piston 302 is 5 mm higher than the cover plate 200, the cover plate 200 is closed, and the bolt assembly 101 is manually and internally connected to the locking pressure plate 203 and then locked. As the air cylinder 400 pushes the piston 302, the pressure in the sealed cavity formed by the water tank 103 and the cover plate 200 increases. At this time, the one-way valve 201 opens, and the residual air and a small amount of cleaning liquid are discharged through the one-way valve 201. Then, the air cylinder 400 retracts the piston 302, and the one-way valve 201 closes. The pressure in the sealed cavity formed by the water tank 103 and the cover plate 200 decreases to form a negative pressure, and the residual air in the micro holes and blind holes of the workpiece to be cleaned is discharged. Thus, the cleaning liquid enters all the micro holes and blind holes. The air cylinder 400 repeats the above actions 2-3 times to ensure that the residual air in the micro holes and blind holes of the workpiece is completely discharged. The air cylinder 400 continues to retract the piston 302 to further reduce the pressure in the sealed cavity formed by the water tank 103 and the cover plate 200. The measurement signal is transmitted into the PLC through the pressure sensor 202 and compared with the preset value. When the preset value in the PLC is reached, the air cylinder 400 stops operating and locks.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
