Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, specifically to an ultrasonic cleaning device for cleaning deep-hole and blind-hole parts. Background Technology

[0002] Deep-hole and blind-hole parts, such as valve bodies, cylinders, slender pipes, and fuel injectors, commonly have complex internal cavity structures including deep holes, blind holes, and intersecting holes. During machining, these parts easily accumulate impurities such as chips, oil, and polishing paste within the holes. Furthermore, due to the small diameter and large depth of the holes, cleaning fluid has difficulty fully penetrating and flowing, making cleaning challenging. Ultrasonic cleaning utilizes the cavitation effect generated by ultrasound in the cleaning fluid, allowing the fluid to penetrate deep into the internal holes of the parts. It is currently a commonly used and effective cleaning method for deep-hole and blind-hole parts. To improve cleaning efficiency, existing ultrasonic cleaning equipment typically includes multiple cleaning tanks, each containing a different cleaning agent, allowing the parts to pass through each tank sequentially for multi-stage cleaning. Simultaneously, to enhance the flushing and renewal effect of the cleaning fluid on the interior of deep holes and blind holes, the parts or cleaning cage also need to undergo reciprocating lifting and lowering motion within the cleaning tank during the cleaning process.

[0003] However, in existing ultrasonic cleaning equipment, the lifting and lowering movement of the cleaning cage or parts within each cleaning tank is generally driven by cylinders. Each cleaning tank typically requires a separate cylinder, along with a corresponding air source, control valve, and air circuit. For multi-stage cleaning equipment, this results in a large number of cylinders, complex air circuit layout, and significant manufacturing costs and space requirements. Furthermore, the synchronous control of multiple sets of cylinders is challenging, and the cylinders, constantly exposed to the humid and corrosive environment of the cleaning fluid, are prone to aging and leakage of seals, leading to a high failure rate and impacting production efficiency and equipment operational stability. These problems become even more pronounced when lifting mechanisms are installed in multiple cleaning tanks to enhance the cleaning effect on deep-hole and blind-hole parts. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic cleaning device for cleaning deep-hole and blind-hole parts, so as to solve the problems mentioned in the background art.

The motor has its output shaft fixedly connected to one end of the worm gear. The motor drives the worm gear to rotate, the worm gear drives the three worm wheels to rotate, the three worm wheels drive the three sets of eccentric wheels to rotate through the three transmission shafts, and the three sets of eccentric wheels drive the three sets of lifting frames to synchronously reciprocate in the primary cleaning tank, the secondary cleaning tank and the tertiary cleaning tank through the three sets of lifting plates and the three sets of lifting rods.

[0006] Preferably, the worm gear is movably installed on the front side wall inside the cleaning equipment housing and is located below the three worm wheels, and is meshed with the three worm wheels; the three worm wheels are respectively fixedly sleeved on one end of the three drive shafts near the front side wall inside the cleaning equipment housing.

[0007] Preferably, it also includes an ultrasonic cleaning mechanism, which includes a pre-cleaning tank, a primary cleaning tank, a secondary cleaning tank, an intermediate tank, and a tertiary cleaning tank. There are two pre-washing tanks, located at the left end of the cleaning equipment housing; four primary cleaning tanks are located at the right end of the pre-washing tanks; two secondary cleaning tanks are located at the right end of the primary cleaning tanks; two intermediate tanks are located at the right end of the secondary cleaning tanks; and three tertiary cleaning tanks are located at the right end of the intermediate tanks. Each of the primary, secondary, and tertiary cleaning tanks is equipped with an ultrasonic generator.

[0008] Preferably, the pre-washing tank is used to pre-clean deep hole and blind hole parts; different cleaning agents are provided in the primary cleaning tank, the secondary cleaning tank and the tertiary cleaning tank, and the concentration of the cleaning agents increases in an ascending order; the intermediate tank is used to further remove the attached stains on the parts after cleaning in the primary cleaning tank and the secondary cleaning tank.

[0009] Preferably, it also includes a feeding and discharging mechanism, which includes a feeding chute, a feeding chain, a discharging chute, and a discharging chain; The feeding trough is fixedly installed at the left end of the cleaning equipment box, and two feeding chains are arranged in parallel inside the feeding trough and rotate inside the feeding trough toward the inside of the cleaning equipment box. The discharge trough is fixedly installed at the right end of the cleaning equipment box, and two discharge chains are arranged in parallel inside the discharge trough and rotate outside the cleaning equipment box inside the discharge trough.

[0010] Preferably, the feeding and discharging mechanism further includes a guide rail, a translation column, a suspension frame, and a cage hook; The guide rail is fixedly installed inside the cleaning equipment housing and close to the rear side wall of the cleaning equipment housing; a translation drive assembly is provided inside the translation column and is movably mounted on the guide rail through the translation drive assembly; a lifting drive assembly is provided on the suspension frame and is movably mounted in the middle of the front side of the translation column through the lifting drive assembly; the cage hooks are fixedly installed at the bottom end of the suspension frame and are arranged in a rectangular structure.

[0011] Preferably, it also includes a control cabinet and a movable door; the control cabinet is provided at both the left and right ends of the cleaning equipment housing, and the movable door is provided on the upper front half of the cleaning equipment housing.

[0012] Preferably, the three sets of lifting rods are located on the front and rear sides of the primary cleaning tank, the secondary cleaning tank and the tertiary cleaning tank, respectively, and are all located inside the cleaning equipment housing; When the end of the eccentric wheel away from the drive shaft rotates upward, it lifts the lifting plate to the top and drives the entire lifting frame to rise through the lifting rod; when the eccentric wheel rotates downward, it drives the lifting frame to descend, so that the three sets of lifting frames continuously reciprocate in the primary cleaning pool, the secondary cleaning pool and the tertiary cleaning pool respectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a mechanical synchronous reciprocating lifting and cleaning mechanism composed of a motor, worm gear, worm wheel, transmission shaft, eccentric wheel, lifting plate, and lifting rod. A single motor can synchronously drive three sets of lifting frames to reciprocate within the primary, secondary, and tertiary cleaning tanks. This replaces the existing technology where each cleaning tank is equipped with a separate cylinder-driven lifting frame, significantly reducing the number of cylinders, simplifying the air circuit and control valve layout, and lowering equipment manufacturing costs and space requirements. Furthermore, due to the synchronous meshing transmission between the worm gear and three worm wheels, the lifting actions of the three sets of lifting frames are highly synchronized, avoiding the asynchronous operation problems caused by multiple cylinders due to air pressure fluctuations and seal leaks. The mechanical transmission mechanism is also more adaptable to humid and corrosive cleaning environments, resulting in more stable and reliable equipment operation, thereby effectively improving production efficiency and equipment lifespan. This invention features a pre-washing tank, a primary cleaning tank, a secondary cleaning tank, an intermediate tank, and a tertiary cleaning tank. Deep-hole and blind-hole parts are pre-cleaned in the pre-washing tank. Different cleaning agents are placed in the primary, secondary, and tertiary cleaning tanks, with the concentrations increasing progressively. The intermediate tank further removes stains adhering to the parts after cleaning in the primary and secondary tanks. A lifting cleaning mechanism drives the cleaning cage to reciprocate within each cleaning tank, ensuring the cleaning solution fully penetrates and continuously flushes and renews the parts. This significantly improves the comprehensiveness and efficiency of cleaning chips, oil, and other impurities in deep holes, blind holes, and intersecting holes, resulting in better cleaning effects and more stable cleaning quality.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] This embodiment provides an ultrasonic cleaning device for cleaning deep-hole and blind-hole parts, such as... Figures 1 to 5As shown, the equipment includes a cleaning equipment housing 1, with control cabinets 2 installed on both the left and right ends of the cleaning equipment housing 1, and a movable door 3 installed on the upper front half of the cleaning equipment housing 1.

[0018] At other levels, this embodiment also provides a feeding / discharging mechanism 4, such as... Figures 1 to 3 As shown, the feeding and discharging mechanism 4 includes a feeding trough 41, a feeding chain 42, a discharging trough 43, a discharging chain 44, a guide rail 45, and a translation column 46.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, the feed trough 41 is fixedly installed at the left end of the cleaning equipment box 1, and two feed chains 42 are arranged in parallel inside the feed trough 41 and rotate inside the cleaning equipment box 1 inside the feed trough 41. The cleaning cage containing deep-hole and blind-hole parts, placed in the feed trough 41, is transported into the cleaning equipment housing 1 by two feed chains 42 that rotate into the housing 1.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, the discharge trough 43 is fixedly installed at the right end of the cleaning equipment box 1, and two discharge chains 44 are arranged in parallel inside the discharge trough 43 and rotate outward from the cleaning equipment box 1 inside the discharge trough 43. The cleaning cage containing parts with deep holes and blind holes, which have undergone ultrasonic cleaning, is transported to the outside of the cleaning equipment housing 1 by two discharge chains 44 that rotate outward.

[0021] In this embodiment, as Figure 2 and Figure 3 As shown, the guide rail 45 is fixedly installed inside the cleaning equipment box 1 and close to the rear side wall of the cleaning equipment box 1. The translation column 46 is provided with a translation drive component and is movably mounted on the guide rail 45 through the translation drive component. The suspension frame 47 is provided with a lifting drive component and is movably mounted in the middle of the front side of the translation column 46 through the lifting drive component. The cage hook 48 is fixedly installed at the bottom of the suspension frame 47 and is arranged in a rectangular structure. The translation column 46 is moved to the cleaning cage inside the cleaning equipment housing 1 by the feed chain 42, so that the cage hook 48 is aligned directly above the cleaning cage. Then, the translation column 46 is moved to the left to avoid the cage hook 48 colliding with the cleaning cage when it descends. Then, the cage hook 48 is lowered by the suspension frame 47. Then, the translation column 46 is moved to the right to reset and then raised to lift the cleaning cage containing the deep hole blind hole parts. Finally, the translation column 46 is moved to the right to bring the cleaning cage into the cleaning stage. After cleaning, the cleaning cage is moved and placed on the discharge chain 44, and the cleaning cage is sent out of the cleaning equipment housing 1 by the discharge chain 44.

[0022] In other aspects, this embodiment also provides an ultrasonic cleaning mechanism 5, such as... Figure 2 As shown, the ultrasonic cleaning mechanism 5 includes a pre-cleaning tank 51, a primary cleaning tank 52, a secondary cleaning tank 53, an intermediate tank 54, and a tertiary cleaning tank 55.

[0023] In this embodiment, as Figure 2 As shown, there are two pre-washing tanks 51, which are located at the left end of the cleaning equipment box 1 and at the right end of the feed trough 41. There are four primary cleaning tanks 52 located at the right end of the pre-washing tanks 51. There are two secondary cleaning tanks 53 located at the right end of the primary cleaning tanks 52. There are two intermediate tanks 54 located at the right end of the secondary cleaning tanks 53. There are three tertiary cleaning tanks 55 located at the right end of the intermediate tanks 54 and at the left side of the discharge trough 43. Each primary cleaning tank 52, secondary cleaning tank 53 and tertiary cleaning tank 55 is equipped with an ultrasonic generator. Pre-cleaning of deep-hole and blind-hole parts is performed in pre-wash tank 51 to improve the efficiency of subsequent ultrasonic cleaning. Different cleaning agents are used in pre-wash tank 51, secondary cleaning tank 53, and tertiary cleaning tank 55 to improve the comprehensiveness of cleaning. By setting up multiple pre-wash tanks 51, secondary cleaning tanks 53, and tertiary cleaning tanks 55, the concentration of cleaning agents is increased in an ascending relationship to improve the cleaning effect. The intermediate tank 54 further removes the attached stains on the parts after cleaning in the primary cleaning tank 52 and secondary cleaning tank 53. Finally, the tertiary cleaning tank 55 is used for final cleaning, which improves the cleaning efficiency.

[0024] At other levels, this embodiment also provides a lifting and cleaning mechanism 6, such as... Figure 4 and Figure 5 As shown, the lifting and cleaning mechanism 6 includes a lifting frame 61, a lifting rod 62, a lifting plate 63, an eccentric wheel 64, a transmission shaft 65, a worm gear 66, a worm 67, and a motor 68.

[0025] In this embodiment, as Figure 4 and Figure 5As shown, there are three sets of lifting frames 61, which are movably installed in the primary cleaning tank 52, the secondary cleaning tank 53, and the tertiary cleaning tank 55, respectively. There are also three sets of lifting rods 62, which are fixedly connected to the front and rear top ends of the three sets of lifting frames 61, and are located on the front and rear sides of the primary cleaning tank 52, the secondary cleaning tank 53, and the tertiary cleaning tank 55, respectively, and are all located inside the cleaning equipment housing 1. Lifting plates 63 are fixedly installed at the bottom end of each set of lifting rods 62. There are also three sets of eccentric wheels 64, which are movably installed. At the bottom of the three sets of lifting plates 63, there are three drive shafts 65, which are fixedly installed between the three sets of eccentric wheels 64. There are three worm gears 66, which are fixedly sleeved on the end of the three drive shafts 65 near the front side wall of the inner side of the cleaning equipment box 1. The worm 67 is movably installed on the front side wall of the inner side of the cleaning equipment box 1, and is located below the three worm gears 66 and meshes with the three worm gears 66. The motor 68 is fixedly installed on the front side wall of the inner side of the cleaning equipment box 1, and its output shaft is fixedly connected to one end of the worm 67. The worm gear 67 is driven to rotate by the motor 68. When the worm gear 67 rotates, it drives the transmission shaft 65 to rotate through the worm wheel 66, causing the eccentric wheels 64 at both ends to rotate simultaneously. When the end of the eccentric wheel 64 away from the transmission shaft 65 rotates upward, it lifts the lifting plate 63 and drives the lifting frame 61 to rise as a whole through the lifting rod 62. When the eccentric wheel 64 rotates downward, it drives the lifting frame 61 to fall. This causes the three sets of lifting frames 61 to continuously reciprocate in the primary cleaning tank 52, the secondary cleaning tank 53, and the tertiary cleaning tank 55, respectively. This allows the cleaning cages in the lifting frames 61 placed in each tank to continuously rise and fall for cleaning, improving cleaning efficiency. Furthermore, by using the worm gear 67 to drive the eccentric wheel 64, the number of cylinders used in traditional lifting structures is reduced, improving production efficiency while saving costs.

[0026] Working principle: In use, the cleaning cage containing the deep-hole blind-hole parts is placed into the feed trough 41, and then fed into the cleaning equipment housing 1 by two feed chains 42 rotating inside the feed trough 41. Subsequently, the translation column 46 moves along the guide rail 45 to above the cleaning cage, aligning the cage hook 48 with the cleaning cage. To avoid collision during descent, the translation column 46 first moves to the left, and then the suspension frame 47 drives the cage hook 48 to descend. Then, the translation column 46 returns to its right position and rises, lifting the cleaning cage. Finally, the translation column 46 moves to the right, driving the cleaning cage into the cleaning stage.

[0027] After entering the cleaning stage, the parts pass through the pre-wash tank 51, the primary cleaning tank 52, the secondary cleaning tank 53, the intermediate tank 54, and the tertiary cleaning tank 55 in sequence. The pre-wash tank 51 pre-cleans the parts with deep holes and blind holes. The primary cleaning tank 52, the secondary cleaning tank 53, and the tertiary cleaning tank 55 are all equipped with ultrasonic generators and contain different cleaning agents, so that the concentration of the cleaning agents increases in an incremental relationship. The intermediate tank 54 further removes the stains attached to the parts after cleaning in the primary cleaning tank 52 and the secondary cleaning tank 53. Finally, the tertiary cleaning tank 55 completes the final cleaning. Simultaneously, motor 68 drives worm gear 67 to rotate, worm gear 67 drives three worm wheels 66 to rotate, and worm wheels 66 drive three transmission shafts 65 to rotate, causing the eccentric wheels 64 at both ends of each transmission shaft 65 to rotate synchronously. When the end of the eccentric wheel 64 away from the transmission shaft 65 rotates upward, it lifts the lifting plate 63 and drives the lifting frame 61 to rise as a whole through the lifting rod 62. When the eccentric wheel 64 rotates downward, it drives the lifting frame 61 to descend, so that the three sets of lifting frames 61 continuously reciprocate in the primary cleaning tank 52, the secondary cleaning tank 53, and the tertiary cleaning tank 55, respectively, driving the cleaning cage to perform lifting and cleaning, thereby improving cleaning efficiency.

[0028] After cleaning, the translation column 46 moves the cleaning cage and places it on the discharge chain 44. The discharge chain 44 rotates in the discharge trough 43 toward the outside of the cleaning equipment box 1, sending the cleaning cage out of the cleaning equipment box 1, thus completing the entire cleaning process.
