Description

Technical Field

[0001] This invention belongs to the technical field of diesel engine cylinder head cleaning, specifically relating to a cleaning device for diesel engine cylinder head processing. Background Technology

[0002] During the machining of diesel engine cylinder heads, impurities or oil stains may adhere to the surface, leading to reduced sealing performance after assembly. Therefore, cleaning is performed before assembly, with ultrasonic cleaning being a common method. However, current cleaning methods require wiping or roughly cleaning the surface first for areas with significant oil or impurities before ultrasonic cleaning, increasing the number of steps. Directly immersing the cylinder head in ultrasonic cleaning increases cleaning time and reduces efficiency, and may also result in incomplete removal of impurities and oil stains. This issue has become a problem that urgently needs to be solved by those in the field. Summary of the Invention

[0003] The purpose of this invention is to provide a cleaning device for machining diesel engine cylinder heads, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cleaning device for diesel engine cylinder head processing, comprising a base, an ultrasonic generator fixed on the upper left side of the base, a cleaning chamber fixed on the right side of the ultrasonic generator, and converters fixed on both the front and rear sides of the inner wall of the cleaning chamber, the ultrasonic generator being electrically connected to the converters; a through hole is provided at the bottom of the cleaning chamber, and a lifting chamber is fixed within the through hole, a hydraulic plate is slidably connected to the inner wall of the lifting chamber, a hydraulic rod is fixed above the hydraulic plate, a mounting plate is fixedly connected to the upper end of the hydraulic rod, the mounting plate is located inside the cleaning chamber, and the cleaning chamber is filled with cleaning agent; the bottom of the lifting chamber is connected to an external hydraulic pump pipeline.

[0005] The present invention further illustrates that an insertion hole is provided between the hydraulic plate and the hydraulic rod, and a slot is provided inside the insertion hole, and an insertion rod is provided inside the slot. A protrusion is provided on the outer side of the insertion rod, and the protrusion is slidably connected to the slot of the insertion hole; a rocker wheel is fixed at the bottom of the insertion rod.

[0006] The present invention further describes that the bottom of the mounting plate is provided with a threaded groove, and a threaded sleeve is threadedly connected in the threaded groove. The threaded sleeve is provided with an annular groove inside. One end of the annular groove is connected to a spiral groove, and the other end of the spiral groove is connected to the annular groove with a drop groove. A sleeve is fixed on one side of the upper end of the lifting cavity, and a push rod is slidably connected inside the sleeve. A spring is provided between the inner end of the push rod and the inner wall of the sleeve. The outer end of the push rod is spherical and is initially embedded in the connection between the annular groove and the spiral groove.

[0007] The present invention further illustrates that a second spring is provided between the bottom of the mounting plate and the top of the lifting cavity, and the second spring is sleeved on the outside of the hydraulic rod.

[0008] The present invention further illustrates that the annular groove is semi-enclosed, and when the push rod moves to the other end of the annular groove and continues to move, the push rod displaces inward.

[0009] The present invention further illustrates that the bottom of the cleaning chamber is provided with a hole, and a limiting rod is slidably connected in the hole, and a limiting groove is provided on one side of the threaded sleeve; the limiting rod is inserted into the limiting groove after moving upward.

[0010] The present invention further explains that after the limiting rod is inserted into the limiting groove, the rocker wheel is rotated counterclockwise.

[0011] The present invention further illustrates that a limiting block is fixed at the bottom of the inner wall of the cleaning chamber, and the limiting block is located below the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention generates high-frequency electrical signals through an ultrasonic generator and transmits them to a converter. The converter converts the signals into mechanical vibrations and transmits them to the cleaning agent. Under the alternating action of the sound waves, the liquid forms microbubbles. When the sound pressure reaches the threshold, the bubbles rapidly expand and suddenly close, generating instantaneous high-pressure shock waves, thereby impacting and cleaning the diesel engine cylinder head. The invention is automated, simple to operate, and improves cleaning efficiency. Furthermore, during the cleaning process, the diesel engine cylinder head vibrates rapidly in the cleaning agent, shaking off internal impurities and thus further improving the cleaning quality and efficiency. When there is a lot of oil and impurities on the surface of the diesel engine cylinder head, the cylinder head can rotate continuously to shake off the surface impurities, further accelerating the cleaning speed. The vibration generated by the continuous rotation of the diesel engine cylinder head enhances the cleaning effect. Attached Figure Description

[0014] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-10 The present invention provides a technical solution: a cleaning device for processing diesel engine cylinder head, including a base 1, an ultrasonic generator 2 fixed on the upper left side of the base 1, a cleaning chamber 3 fixed on the right side of the ultrasonic generator 2, and a converter 4 fixed on both the front and rear of the inner wall of the cleaning chamber 3, and the ultrasonic generator 2 and the converter 4 are electrically connected. The bottom of the cleaning chamber 3 is provided with a through hole, and a lifting chamber 31 is fixed inside the through hole. A hydraulic plate 311 is slidably connected to the inner wall of the lifting chamber 31. A hydraulic rod 312 is fixed above the hydraulic plate 311. A mounting plate 32 is fixedly connected to the upper end of the hydraulic rod 312. The mounting plate 32 is located inside the cleaning chamber 3, and the inside of the cleaning chamber 3 is filled with cleaning agent. The bottom of the lifting chamber 31 is connected to an external hydraulic pump pipeline; An external hydraulic pump fills the lifting chamber 31 with liquid, increasing the hydraulic pressure below the hydraulic plate 311. This pushes the hydraulic plate 311 upward along the inner wall of the lifting chamber 31, causing the mounting plate 32 to move upward via the hydraulic rod 312, extending it out of the cleaning chamber 3. The diesel engine cylinder head is then placed on the mounting plate 32, and the external hydraulic pump extracts the liquid from the lifting chamber 31, resetting the mounting plate 32 and immersing the diesel engine cylinder head in the cleaning agent. Then, the ultrasonic generator 2 operates, generating a high-frequency electrical signal that is transmitted to the converter 4. The converter 4 converts this signal into mechanical vibration, which is then transmitted to the cleaning agent. Under the alternating action of the sound waves, the liquid forms tiny bubbles. When the sound pressure reaches the threshold, the bubbles rapidly expand and suddenly collapse, generating a momentary high-pressure shock wave, thereby impacting and cleaning the diesel engine cylinder head. This automated operation is simple and improves cleaning efficiency.

[0016] A socket is provided between the hydraulic plate 311 and the hydraulic rod 312, and a slot is provided in the socket, and a rod 33 is provided inside. A protrusion is provided on the outside of the rod 33, and the protrusion is slidably connected to the slot of the socket. A rocker wheel 34 is fixed to the bottom of the insertion rod 33; Example 1: like Figure 9 As shown, during the cleaning process, the converter 4 performs ultrasonic vibration cleaning on the front and back of the diesel engine cylinder head. Afterwards, the operator can rotate the rocker wheel 34, which drives the hydraulic rod 312 and hydraulic plate 311 to rotate through the protrusion of the insert rod 33. The rotation of the hydraulic rod 312 drives the mounting plate 32 to rotate, making it rotate 90 degrees. At this time, the converter 4 cleans the left and right sides of the diesel engine cylinder head. The cleaning quality is improved, and the cylinder head can be cleaned evenly around all four sides, and the cleaning efficiency is also relatively improved.

[0017] The bottom of the mounting plate 32 is provided with a threaded groove, and a threaded sleeve 35 is threadedly connected in the threaded groove. An annular groove 351 is provided inside the threaded sleeve 35. One end of the annular groove 351 is connected to a spiral groove 352, and the other end of the spiral groove 352 is connected to the annular groove 351 with a drop groove 353. A sleeve 36 is fixed to one side of the upper end of the lifting cavity 31, and a push rod 361 is slidably connected inside the sleeve 36. A spring 362 is provided between the inner end of the push rod 361 and the inner wall of the sleeve 36. The outer end of the push rod 361 is spherical and is initially embedded in the connection between the annular groove 351 and the spiral groove 352.

[0018] A second spring 37 is provided between the bottom of the mounting plate 32 and the top of the lifting cavity 31, and the second spring 37 is sleeved on the outside of the hydraulic rod 312; Example 2: like Figure 7As shown, rotating the rocker wheel 34 clockwise causes the mounting plate 32 to rotate clockwise, which in turn drives the threaded sleeve 35 to rotate clockwise. The push rod 361 moves relative to the threaded sleeve 35. The clockwise rotation of the threaded sleeve 35 causes the push rod 361 to enter the spiral groove 352 from the annular groove 351 and move with the spiral. The threaded sleeve 35 is pressed down by the push rod 361, causing the mounting plate 32 to move downward. Previously, since the mounting plate 32 was in the initial reset state, when it moves downward, it presses the second spring 37 to deform. At the same time, the hydraulic rod 312 and the hydraulic plate 311 move downward. After the push rod 361 reaches the end of the spiral groove 352, it falls into the drop groove 353 and returns to the annular groove 351 through the drop groove 353. The second spring 37 generates a reaction force to push the mounting plate 32 to quickly reset upward, thereby causing the diesel engine cylinder head to vibrate rapidly in the cleaning agent, shaking off the impurities inside, thus further improving the cleaning quality and significantly increasing the cleaning efficiency.

[0019] The annular groove 351 is semi-closed, and when the push rod 361 moves to the other end of the annular groove 351 and continues to move, the push rod 361 is displaced inward. Example 3: like Figure 8 As shown, the surface of the diesel engine cylinder head is covered with a lot of oil and impurities. At this time, the operator can rotate the rocker wheel 34 counterclockwise, which will drive the mounting plate 32 to rotate counterclockwise. The push rod 361 slides in the annular groove 351. Continuing to rotate the rocker wheel 34 will make the diesel engine cylinder head rotate continuously, shaking off the impurities on its surface, further accelerating the cleaning speed. There is no limit to the number of rotations, allowing for thorough cleaning. When the push rod 361 slides to the end of the annular groove 351, it will disengage from the annular groove 351 if it continues to slide. The push rod 361 will then contact and adhere to the inner wall of the threaded sleeve 35, compressing the push rod 361 and deforming the spring 362 until the push rod 361 re-enters the annular groove 351. The spring 362 will generate a reaction force, causing the push rod 361 to re-enter the annular groove 351 with a certain impact force. This will cause the diesel engine cylinder head to vibrate while rotating continuously, enhancing the cleaning effect.

[0020] The bottom of the cleaning chamber 3 is provided with a hole, and a limit rod 38 is slidably connected inside the hole. A limit groove is provided on one side of the threaded sleeve 35. After the limit rod 38 moves upward, it is inserted into the limit groove.

[0021] After the limit rod 38 is inserted into the limit groove, the rocker wheel 34 is rotated counterclockwise; Example 4: like Figure 10As shown, after multiple cleaning operations, the fatigue of spring 37 increases. The operator pushes the limiting rod 38 upward, so that the limiting rod 38 is inserted into the limiting groove of the threaded sleeve 35 to limit and fix it. Then the operator rotates the rocker wheel 34, and the mounting plate 32 rotates. Through its threaded groove, it is threadedly connected to the threaded sleeve 35, so that the mounting plate 32 moves towards the threaded sleeve 35 through the threaded groove. After the mounting plate 32 moves downward, it presses down on spring 37. The initial deformation strength of spring 37 is guaranteed, and the strength of the diesel engine cylinder head's up-and-down movement in embodiment 2 is guaranteed, so as to continuously and effectively shake off the impurities on the diesel engine cylinder head, and make full use of spring 37, reducing its replacement frequency and reducing costs.

[0022] A limiting block is fixed at the bottom of the inner wall of the cleaning chamber 3, and the limiting block is located below the threaded sleeve 35; Example 5: like Figure 10 As shown, when spring 37 has just been replaced or when its elastic strength is sufficient, the operator can also press spring 37 by lifting the limit rod 38 in the manner described in Example 4, thereby increasing its deformation strength, increasing its strength when jumping up and down on the mounting plate 32, increasing the strength of shaking off impurities, and greatly improving the cleaning effect. The entire cleaning device has a simple structure, low manufacturing cost, and is suitable for diesel engine cylinder heads with various cleaning difficulties.
