Description

Technical Field

[0001] The invention relates to the technical field of automatic cleaning, in particular to an automatic cleaning device for precision parts after casting. Background Art

[0002] Precision parts generally refer to mechanical parts or components that are manufactured with extremely high precision and very small tolerances. These parts need to be produced under strict specifications to ensure that their size, shape and surface quality meet the set requirements. They are commonly found in aerospace, medical equipment, electronics industry, automotive industry and optical instruments. Their manufacturing process usually uses CNC machine tools (CNC), electrical discharge machining (EDM), laser cutting, precision casting and additive manufacturing (3D printing).

[0003] Among them, the production process of pipe interface accessories in engines in the automotive industry, some components in valve bodies and pumps, and accessories used in food and medical applications requires precision casting. After casting, the parts need to be cleaned to remove molding sand and investment materials, clean oxide scale and rust, remove burrs and flash, and improve surface quality. Currently, the cleaning is mainly carried out through mechanical cleaning, chemical cleaning, electrolytic cleaning, and ultrasonic cleaning. During ultrasonic cleaning, the parts are first placed in a box filled with liquid, and then ultrasonic waves are emitted by the transmitter arranged on the box for cleaning. During the process, the parts are driven to rotate slowly, and finally rinsed by spraying clean water. The ultrasonic cleaning technology relies on the impact of the generated tiny bubbles (cavitation) to achieve the cleaning purpose.

[0004] The current cleaning process has the following problems: the shapes of local components are irregular, and the current method of placing the components still and rotating them slowly makes it difficult for all parts of the components to be cleaned by the bubbles generated by the ultrasound. That is, the bubbles generated by the ultrasound in this process are difficult to impact this part of the area, and at the same time, in the subsequent spray flushing process, this part of the area is difficult to contact with clean water, which is prone to shadow effects and standing waves, resulting in poor overall cleaning effect.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2As shown, an automatic cleaning device for precision parts after casting includes: a cleaning box 1, the upper end of the cleaning box 1 is open, the upper end of the cleaning box 1 is provided with a sealing plate 2 for sealing the cleaning box 1, a rotating pile 3 with a vertical axis rotates through the bottom of the inner cavity of the cleaning box 1, the rotating pile 3 is connected to an external motor, and two left-right symmetrical fixed piles 30 with vertical axes are fixedly provided on the bottom wall of the inner cavity of the cleaning box 1, and a storage mechanism 4 is provided on the two fixed piles 30.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the cleaning box 1 is divided into a loading and unloading area 5, a spraying area 6 and a cleaning area 7 from top to bottom, and a transmitter 8 for generating ultrasonic waves is provided on the rotating pile 3 and the circumferential inner wall of the cleaning box 1, and a plurality of nozzles 9 are fixedly provided below the sealing plate 2.

[0037] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the storage mechanism 4 includes a fixed frame 40, a plurality of fixed frames 40 are slidably arranged between two fixed piles 30 and are evenly distributed around the rotating pile 3, a fan-shaped mesh plate 400 is fixedly arranged between two adjacent fixed frames 40, an annular mesh plate 401 is fixedly arranged on all the fixed frames 40, and a fixed unit 41 is arranged on all the fixed frames 40, and the fixed unit 41 includes a fixed ring frame 410, and the fixed frames 40 are all rotatably arranged with a fan-shaped fixed ring frame 410, and the fixed ring An elastic net 411 is fixedly provided on the upper end surface of the frame 410, and a locking unit 42 is provided on the rotating pile 3. After the fixed ring frame 410 drives the elastic net 411 to bind the components, all the fixed ring frames 410 are locked by the locking unit 42. An adjustment unit 44 for driving the fixed frame 40 to move up and down and adjust the angles of the fixed frame 40, the fan-shaped mesh plate 400 and the annular mesh plate 401 is provided between the two fixed piles 30. The adjustment unit 44 includes an adjustment ring 445, and the adjustment ring 445 is located below the fixed frame 40.

[0038] See also Figure 2 and Figure 3In the initial state, the placement station formed by the fixed frame 40 and the fan-shaped mesh plate 400 is located in the loading and unloading area 5. The parts to be cleaned are manually placed on the corresponding fan-shaped mesh plate 400. The adjustment unit 44 works to move the fixed frame 40 downward. In the process of the fixed frame 40 moving downward into the spray area 6, the locking unit 42 first drives the fixed ring frame 410 to drive the elastic net 411 thereon to cover the corresponding parts, and then the fixed ring frame 410 is locked. The fixed frame 40 continues to move downward so that the fan-shaped mesh plate 400 and the parts move down to the cleaning area 7. The external motor and the transmitter 8 work at the same time, the rotating pile 3 drives all parts to rotate synchronously, and the transmitter 8 emits ultrasonic waves and uses the liquid in the cleaning area 7 to ultrasonically clean the parts. After the cleaning is completed, the adjustment unit 44 works to drive the fixed frame 40 to move up to the spray area 6, and the nozzle 9 sprays clean water to spray and rinse the parts. After the rinsing is completed, the fixed frame 40 drives the parts to move up, the locking unit 42 is unlocked, and the cleaned parts are taken out.

[0039] Secondly, during the ultrasonic cleaning and spray flushing process, the inclination angles of all the fixing frames 40 and components are adjusted by adjusting the adjustment ring 445 in the adjustment unit 44, and multi-angle ultrasonic cleaning and multi-angle spray flushing are performed to improve the overall cleaning effect of the components.

[0040] like Figure 1 and Figure 6 As shown, the storage mechanism 4 also includes a partition plate 402. A cross-shaped partition plate 402 is fixedly provided on the upper end surface of the fan-shaped mesh plate 400. The partition plate 402 divides the space formed by covering the fixed ring frame 410 and the elastic net 411 thereon into multiple small spaces, and when placing components, the components are placed separately in each small space.

[0041] During operation, the area of ​​the fan-shaped mesh plate 400 is divided into multiple spaces by the partition plate 402 on the fan-shaped mesh plate 400, so it is convenient for the staff to place the components separately, which facilitates the placement process and improves the space utilization of the fan-shaped mesh plate 400. Secondly, when the size of a single component is larger than the single space formed by the partition plate 402, the component is placed on the partition plate 402, and only one component is placed on the partition plate 402. At this time, the partition plate 402 replaces the supporting function of the fan-shaped mesh plate 400 below, and cooperates with the elastic properties of the elastic net 411 to still lock the components and ensure stability.

[0042] During the process of placing components, the partition plate 402 separates adjacent components to avoid the problem of adjacent components colliding and being damaged during the subsequent rotation process.

[0043] like Figure 1 , Figure 2 and Figure 3As shown, the plurality of nozzles 9 are equidistantly distributed circumferentially with the rotating pile 3 as the center, the sealing plate 2 is provided with through holes 20 corresponding one to one with the fixed piles 30, the upper end surface of the sealing plate 2 is rotatably provided with a docking tube 21 with a vertical axis, the sealing plate 2 is provided with a docking groove connected to the cavity of the docking tube 21, when the sealing plate 2 is moved down to seal the cleaning box 1, the fixed pile 30 passes through the corresponding through hole 20, the rotating pile 3 passes through the docking groove and is inserted into the docking tube 21.

[0044] During operation, after the components are placed and the fixed frame 40 drives the components to move downward, the sealing plate 2 is manually moved downward so that the sealing plate 2 covers the upper opening of the cleaning box 1. Finally, the fixing pile 30 passes through the through hole 20 and the rotating pile 3 is inserted into the docking tube 21, so that the cleaning box 1, the fixed pile 30, the rotating pile 3 and the sealing plate 2 form a frame, thereby improving the stability of the rotating pile 3 during rotation.

[0045] Multiple nozzles 9 are connected to an external water pump (not shown in the figure) through pipes. After the sealing plate 2 blocks the cleaning box 1, the components are first ultrasonically cleaned in the cleaning area 7, and then the fixed frame 40 drives the components to move up to the spraying area 6 for spraying. At this time, multiple nozzles 9 are located above the fan-shaped mesh plate 400, and the external water pump works to pump the existing external clean water into the pipe and spray it out from the nozzle 9. At this time, the external motor still drives the rotating pile 3, the fixed frame 40 and the components to rotate synchronously, and the clean water sprays and rinses the components, and cooperates with the circumferential rotation of the components to improve the spray cleaning effect of the components.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the adjustment unit 44 also includes a sliding block 440. The fixed pile 30 is provided with a sliding block 440 that slides up and down. The lower end surface of the adjustment ring 445 slides left and right and is provided with a rectangular block 446 that corresponds to the sliding block 440 one by one. The rectangular block 446 is hinged with the corresponding sliding block 440. When the adjustment ring 445 is tilted, the rectangular block 446 can slide left and right adaptively to avoid the problem of jamming between the adjustment ring 445 and the sliding block 440. The sliding block 440 is fixed together with the bottom of the cleaning box 1. A return spring 441 is provided on the fixed pile 30, a sliding bar 442 corresponding to the fixed frame 40 is circumferentially slidably provided on the adjusting ring 445, the upper end surface of the sliding bar 442 is ball-hinged with an articulated seat, a horizontal rod 443 with a horizontal axis is fixedly provided on the fixed frame 40, the horizontal rod 443 slides along its axial direction and passes through the corresponding articulated seat, a driving block 444 that slides up and down is provided on the fixed pile 30, and an external electric push rod with a vertical axis is fixedly provided between the two driving blocks 444 and the sealing plate 2.

[0047] like Figure 5As shown, the circumferential surface of the rotating pile 3 is penetrated by two left-right symmetrical rectangular grooves 412, and a connecting ring 413 is fixedly arranged between all the fixing frames 40, and a rectangular bar 414 with one end located in the rectangular groove 412 is fixedly arranged on the inner ring surface of the connecting ring 413, and a buffer space is provided between the rectangular bar 414 and the longitudinal inner wall of the corresponding rectangular groove 412, so as to avoid the problem of the rectangular bar 414 and the inner wall of the rectangular groove 412 being stuck when the adjusting ring 445 is adjusted to tilt.

[0048] In the initial state, the elastic properties of the two return springs 441 support the adjustment ring 445 and the fixed frame 40, and the fixed frame 40 is placed in the loading and unloading area 5 at this time. Then, the required cleaning parts are placed manually. After the parts are placed, all external electric push rods work to move their telescopic ends downward, and their telescopic ends push the driving block 444 to move downward synchronously. During the downward movement of the driving block 444, the driving block 444 pushes the sliding block 440 to move downward synchronously, the return spring 441 is compressed, and the sliding block 440 drives the adjustment ring 445 and the fixed frame 40 to move downward synchronously, so that the parts move downward from the loading and unloading area 5 through the spraying area 6 and finally move to the cleaning area 7. During the movement of the fixed frame 40 in the loading and unloading area 5, the locking unit 42 operates to make the fixed ring frame 410 and the elastic net 411 cover the parts and complete the locking action, and then enter the spraying area 6.

[0049] Secondly, during the spraying or ultrasonic cleaning process, after a period of spraying or ultrasonic cleaning, first the external motor stops working, and the right external electric push rod works to retract its telescopic end to the set length, and the elastic force generated by the compression deformation of the corresponding return spring 441 causes the corresponding sliding block 440 and the driving block 444 to move up synchronously, so the left and right sliding blocks 440 tilt left and right, thereby causing the adjustment ring 445, the fixing frame 40, the fan-shaped mesh plate 400 and the components to tilt synchronously, so during the spraying process or ultrasonic cleaning process, the inclination angle of the component is changed. During the spraying process, a local area on the component can be exposed to the spray surface under the nozzle 9, thereby improving the spray cleaning effect and avoiding the problem of local areas on the component not being cleaned. During the ultrasonic cleaning process, the above-mentioned adjustment of the component to a tilt angle can reduce the shadow effect, promote the circulation of the solution and avoid the standing wave phenomenon, thereby ultimately improving the cleaning effect of the ultrasonic wave on the component.

[0050] like Figure 2 , Figure 6 , Fig. 9 and Fig.10As shown, the locking unit 42 also includes a fixed block 420, and two groups of block groups distributed along the length direction of the fixed frame 40 are fixedly arranged on the fixed frame 40, and the block group includes two fixed blocks 420 distributed along the length direction of the corresponding fixed frame 40, and a connecting block 421 is rotatably arranged on the fixed block 420 through a rotating shaft 429, and a fixed ring frame 410 is fixedly arranged on the corresponding two connecting blocks 421, and a locking block 422 is fixedly arranged on the other side of the fixed ring frame 410 away from the corresponding connecting block 421, and a locking groove 423 is opened through the locking block 422 and the fixed frame 40 from top to bottom, and a transition ring that slides up and down is sleeved on the rotating pile 3, and an annular plate 424 is arranged on the transition ring, and a horizontal bar 425 corresponding to the locking block 422 is fixedly arranged on the annular plate 424, and a locking column 426 with a vertical axis is fixedly arranged on the lower end surface of the horizontal bar 425.

[0051] like Figure 4 , Figure 7 , Figure 8 , Fig. 9 and Fig.11 As shown, the locking column 426 is located directly above the locking groove 423 on the fixing frame 40, a lower pressure plate 427 is fixedly sleeved on the locking column 426, a connecting ring 45 is rotatably provided on the upper end surface of the annular plate 424, the left driving block 444 is ball-jointed with the connecting ring 45 through a U-shaped bar 428, two left-right symmetrical matching grooves are provided on the inner ring surface of the transition ring, and a connecting block 450 corresponding to the matching grooves and located in the matching grooves is fixedly provided on the annular plate 424.

[0052] It should be noted that: by providing sufficient buffer space between the adapter groove and the connecting block 450, it is avoided that when the adjustment ring 445 drives the fixing frame to deflect, the connecting block 450 and the transition ring are stuck and cannot deflect.

[0053] like Figure 5 , Fig. 9 , Fig.10 and Fig.11 As shown, an auxiliary component 43 is commonly provided between the rotating shaft 429 and the corresponding fixed frame 40, and the auxiliary component 43 includes a accommodating box 430. The accommodating box 430 is fixedly provided on the fixed frame 40, and the rotating shaft 429 passes through the cavity of the accommodating box 430. A rope 431 is wound around the rotating shaft 429, and the rope 431 passes through the corresponding fixed frame 40. A pushing plate 432 is commonly fixedly provided at the free ends of the two corresponding ropes 431 on the same fixed frame 40, and a rectangular plate 433 located above the lower pressure plate 427 is fixedly provided on the locking column 426, and a pushing column 434 passing through the corresponding fixed frame 40 is fixedly provided on the lower end surface of the rectangular plate 433, and a volute spring 435 is commonly fixedly provided between the rotating shaft 429 and the fixed block 420.

[0054] like Fig. 9 and Fig.10 As shown, the upper end surface of the rectangular plate 433 is provided with grooves 436 corresponding to the corresponding push pillars 434 .

[0055] When the fixing frame 40 moves down from the loading and unloading area 5 to the spraying area 6, the components have been placed on the corresponding fan-shaped mesh plate 400. The specific process is as follows: first, all the external electric push rods work so that their telescopic ends push the corresponding driving blocks 444 to move down synchronously. The left driving block 444 drives the annular plate 424 to move down synchronously through the U-shaped bar 428. The annular plate 424 drives all the horizontal bars 425 and the locking column 426 thereon to move down synchronously. The locking column 426 drives the rectangular plate 433 and the pushing column 434 thereon to move down synchronously. The pushing column 434 first penetrates the fixing frame 40 and is stuck in the groove 436 on the corresponding rectangular plate 433. As the locking column 426 continues to move downward, the pushing column 434 pushes the rectangular plate 433 and pulls the rotating shaft 429 through the rope 431, the spiral spring 435 is deformed, and the rotating shaft 429 drives the fixed ring frame 410 thereon to rotate synchronously. Therefore, the fixed ring frame 410 drives the elastic net 411 thereon to cover the components on the corresponding fan-shaped mesh plate 400, completing the limiting constraint of the components. Secondly, the fixed ring frame 410 drives the locking block 422 thereon to rotate synchronously, so that the locking block 422 is fitted with the corresponding fixed frame 40. At this time, the locking groove 423 on the locking block 422 is opposite to the locking groove 423 on the corresponding fixed frame 40.

[0056] Afterwards, as the locking column 426 continues to move downward, the locking column 426 moves downward and passes through the corresponding locking groove 423, and the locking column 426 drives the lower pressure plate 427 to finally press the corresponding locking block 422, thereby completing the rigid locking of the fixed ring frame 410. At this time, the left driving block 444 moves downward and contacts the left sliding block 440. The above process is completed in the loading and unloading area 5, and after the subsequent cleaning is completed, the fixed frame 40 moves up and causes the sliding block 440 to move up and reset to the initial position. At this time, the external electric push rod works to drive the driving block 444 to move upward, and the locking block 422 moves up and disengages from the corresponding locking groove 423. The elastic force generated by the deformation of the volute spring 435 causes the rotating shaft 429 to drive the fixed ring frame 410 to rotate and reset, thereby releasing the covering limit of all components, and then the staff takes out the cleaned components.

[0057] In summary, the locking process of the fixed ring frame 410 is completed through the cooperation between the above-mentioned locking column 426 and the corresponding locking groove 423, thereby improving the stability of the component during cleaning and spraying during the rotation process.

[0058] It should be noted that in the above process, the locking process is driven by the downward movement of the driving block 444 on the left side. Therefore, when adjusting the inclination angle of the fixing frame 40 and the components, the right external electric push rod moves upward, and the telescopic end of the left external electric push rod remains stationary, ensuring that when the angle is adjusted for cleaning or spraying, the fixed ring frame 410 and the elastic net 411 always restrain the corresponding components.

[0059] Secondly, the aperture of the groove 436 is larger than the diameter of the corresponding push column 434, so that the push column 434 can be easily inserted into the corresponding groove 436 and drive the corresponding push plate 432 to move downward.

[0060] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0061] In addition, the terms "first", "second", "number one", "number two" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "number one", "number two" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0062] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
