Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to an online workpiece cleaning device for CNC machine tools. Background Technology

[0002] Currently, with the advancement of smart factories, more and more CNC machine tools are being integrated with other automated equipment. In particular, after CNC machine tools have finished machining a workpiece, because coolant is sprayed during machining and chips are generated during cutting, these chips and coolant adhere to the surface of the workpiece. Therefore, the workpiece usually needs to be cleaned after machining.

[0003] The existing Chinese patent with publication number CN115007548A discloses an online cleaning system for workpieces, including a cleaning station and a conveying system for conveying workpieces processed in the previous process to the cleaning station; the conveying system includes a conveying mechanism and workpiece loading mechanisms spaced apart on the conveying mechanism along the conveying direction; one end of the conveying mechanism extends into the discharge position of the processing equipment corresponding to the previous process to form a loading position, the other end of the conveying mechanism forms a unloading position, and the part of the conveying mechanism located between the loading position and the unloading position forms a cleaning position that passes through the cleaning station.

[0004] The aforementioned technologies, as described in their specifications, primarily involve cleaning the processed battery cover. The battery cover is placed at the loading position and conveyed by a conveyor mechanism to the cleaning station, where a cleaning machine provides the cleaning function. However, when the product to be cleaned is a cylindrical structure, the cleaning machine cannot easily clean the inner wall of the cylindrical structure, resulting in a limited cleaning range and affecting the cleaning effect on the cylindrical structure. Summary of the Invention

[0005] To facilitate effective cleaning of the interior of cylindrical products and ensure comprehensive cleaning, this application provides an online cleaning device for CNC machine tools.

[0006] The online workpiece cleaning device for CNC machine tools provided in this application adopts the following technical solution:

[0007] An online cleaning device for CNC machine tools includes a conveyor belt and a limiting plate located on both sides of the conveyor belt. A rinsing assembly includes an outer cleaning component and an inner cleaning component. The outer cleaning component is disposed on the opposite side of the two limiting plates and is used to rinse the outer side of the cylindrical product. The inner cleaning component is located above the conveyor belt and is used to rinse the inner side of the cylindrical product. When the cylindrical product moves on the conveyor belt, the inner cleaning component passes through the interior of the cylindrical product.

[0008] By adopting the above technical solution, after the cylindrical product is cleaned on the CNC machine tool, it can be placed horizontally on the conveyor belt. The limiting plate can limit the opposite sides of the product, so that the axis of the product is parallel to the axis of the conveyor belt. During the conveyor belt transport process, the outer cleaning component can rinse the outer part of the product, while the inner cleaning component can extend into the product to clean the inside of the product, so as to facilitate effective cleaning of the inside of the cylindrical product and ensure comprehensive cleaning of the cylindrical product.

[0009] Preferably, the external cleaning component includes an outer tube and a plurality of external nozzles. The outer tube is disposed on one side of the limiting plate facing each other, and the external nozzles are spaced apart from the outer tube and face the other limiting plate.

[0010] By adopting the above technical solution, the outer pipe can be connected to a water source. When the conveyor belt transports the product forward, the water sprayed from the outer nozzle can rinse the outside of the product.

[0011] Preferably, the inner cleaning component includes an inner tube and a plurality of inner nozzles. The inner tube is located above the conveyor belt and is arranged along the conveying direction of the conveyor belt. The inner nozzles are arranged outside the inner tube and surround the outer side of the inner tube.

[0012] By adopting the above technical solution, one end of the inner tube can be connected to a water source. When the product is placed on the conveyor belt, the product is wrapped around the outside of the inner tube. At this time, the inner tube is also inserted into the inside of the product. Therefore, during the product's transportation process, the inner spray located inside the product can clean the inside of the product.

[0013] Preferably, it further includes a moving part and a driving assembly. The moving part is slidably disposed on the outside of the conveyor belt, and the sliding direction of the moving part is parallel to the sliding direction of the conveyor belt. The driving assembly of the moving part is used to drive the moving part to slide. A lifting block is disposed on the moving part. The lifting block is adjusted along the height direction. The inner tube is disposed on the lifting block. A first adjusting member is disposed on the moving part for driving the lifting block to move and adjust.

[0014] By adopting the above technical solution, when the product is conveyed on the conveyor belt to a position near the output end, the product has basically been cleaned. Since the inner tube is located near the central axis of the product, the lifting block and the inner tube can be adjusted upward synchronously by the first adjusting component until the inner tube contacts the upper inner wall of the product. Therefore, the inner tube can lift the product upward. Then, the driving component drives the moving part, the product and the inner tube to move away from the output end of the conveyor belt until the product leaves the position between the two limit plates and directly above the conveyor belt, making it easy to remove the product from the inner tube.

[0015] Preferably, the lifting block is provided with a rotating block for rotation adjustment. The rotation axis of the rotating block is horizontally set and perpendicular to the conveying direction of the conveyor belt. The lifting block is provided with a second adjusting member for driving the rotating block to rotate and adjust. The inner tube is set on the rotating block. A collecting belt is set below the output end of the conveyor belt.

[0016] By adopting the above technical solution, when the product is lifted by the inner tube and transported to the output end away from the conveyor belt, the second adjusting component drives the end of the inner tube near the conveyor belt to rotate downward. At this time, the product supported by the inner tube slides off the inner tube onto the collecting belt and is transported to the required position by the collecting belt. Therefore, there is no need for manual removal of the product from the inner tube, which is more convenient.

[0017] Preferably, a plurality of support columns are provided on the outer side of the inner tube, the support columns are spaced apart on the upper side of the inner tube, and a ball bearing is embedded and tumbled at the end of the support column away from the outer side of the inner tube. The distance from the ball bearing to the outer side of the inner tube is greater than the distance from the end of the nozzle to the outer side of the inner tube, and the ball bearing is close to the upper inner side of the product.

[0018] By adopting the above technical solution, since the inner tube is close to the product axis, and the ball bearings at the end of the support column can be closer to the upper inner side of the product, the rising distance between the lifting block and the inner tube can be reduced. This ensures that the product is supported by the support column and reduces the wear between the product and the inner nozzle when the product slides off the outside of the inner tube, making it easier for the product to slide off the inner tube quickly. At the same time, since the support column is close to the upper inner side of the product, the product will not be significantly deviated in the conveying direction of the conveyor belt when the inner nozzle is rinsing.

[0019] Preferably, a threaded sleeve is provided on the outer side of the inner tube, and the support column is threadedly connected to the threaded sleeve.

[0020] By adopting the above technical solution, since the inner diameter of the products differs, the distance between the end of the support column and the inner side of the upper end of the product can be adjusted when the support column is rotated, so that the end of the support column can be close to the inner side of the upper end of the product, so as to better limit the product conveying direction and improve applicability.

[0021] Preferably, the upper end of the limiting plate is provided with a top plate, which covers the gap between two adjacent limiting plates.

[0022] By adopting the above technical solution, the top plate can cover the upper part between the two limiting parts, reducing water splashing to the outside during rinsing of the rinsing component.

[0023] Preferably, a collection trough is provided below the conveyor belt, and the conveyor belt is located at the upper opening of the collection trough.

[0024] By adopting the above technical solution, the water generated during the rinsing of the rinsing components can be collected through the collection tank.

[0025] Preferably, the inner tube includes a rigid part and a flexible part that are interconnected, the rigid part being located on the side of the lifting block near the conveyor belt, and the inner nozzle being disposed on the rigid part.

[0026] By adopting the above technical solution, the rigid part can ensure that the inner tube provides stable support and lifts the product, while the flexible part can be easily moved and bent, ensuring that the inner tube can move and rotate.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] (1) By setting the limit plate, the inner cleaning component and the outer cleaning component together, the inner cleaning component can enter the inside of the product during product conveying, so as to facilitate effective cleaning of the inside of the cylindrical product and ensure comprehensive cleaning of the cylindrical product.

[0029] (2) By setting the cooperation between the moving part, the drive assembly, the lifting block and the first adjusting part, the inner tube can lift the product upward and move the product to a position outside the conveyor belt, so that the product can be taken off the inner tube.

[0030] (3) By setting up the cooperation between the collection belt, the second adjusting component and the rotating block, the inner tube can be driven to rotate, so that the product can automatically slide from the inclined inner tube onto the collection belt and then be transported to the required position without manual operation, which is more convenient.

[0031] (4) By setting the cooperation between the support column and the ball, the ball is close to the inner side of the upper end of the product, so the conveying direction of the product conveying and cleaning can be limited to a certain extent, so that the product is conveyed stably on the conveyor belt; and it can reduce the friction between the inner side of the product and the inner nozzle, while making it easier for the product to slide off the outside of the inclined inner tube.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an online workpiece cleaning device for CNC machine tools, mainly for cleaning cylindrical products with open ends and a hollow interior. It can be installed on one side of the CNC machine tool to immediately clean products processed by the CNC machine tool. (Refer to...) Figure 1 and Figure 2 The online cleaning device includes a conveyor belt 1, a limiting plate 2, a top plate 3, a rinsing assembly 4, and a collection tank 5.

[0039] The collection tank 5 is a box-shaped structure with an open top. A rectangular slot is provided at the top of the collection tank 5, and its horizontal cross-section is rectangular. A conveyor belt 1 is horizontally installed at the upper slot of the collection tank 5. The conveying direction of the conveyor belt 1 is consistent with the length direction of the collection tank 5. The width of the conveyor belt 1 is smaller than the width of the slot in the collection tank 5. One end of the conveyor belt 1 is the input end, and the other end is the output end. Both ends of the conveyor belt 1 extend beyond the slot of the collection tank 5, and several water-permeable holes 16 are provided on the conveyor belt 1. The product to be cleaned is placed horizontally on the conveyor belt 1 for conveying and cleaning, ensuring that the product's axis is consistent with the conveying direction of the conveyor belt 1. The collection tank 5 collects the cleaning water.

[0040] The limiting plate 2 is rectangular and consists of two pieces. The limiting plate 2 is fixed near the long side of the collection tank 5 and is located on both sides of the conveyor belt 1. The upper part of the limiting plate 2 is higher than the highest position when the product is placed on the conveyor belt 1. The top plate 3 is fixed on the upper side of the limiting plate 2 and is used to cover the upper part between the two limiting plates 2. Through the blocking effect of the limiting plate 2 and the top plate 3, the water splashing to the outside during cleaning is reduced.

[0041] The rinsing assembly 4 includes an outer cleaning component 41 and an inner cleaning component 42. The outer cleaning component 41 is disposed on one side of the two limiting plates 2 facing each other and is used to rinse the outer side of the cylindrical product. The inner cleaning component 42 is disposed on the limiting plate 2 and located above the conveyor belt 1 and is used to rinse the inner side of the cylindrical product. When the cylindrical product moves on the conveyor belt 1, the inner cleaning component 42 passes through the interior of the cylindrical product, thus also cleaning the interior of the product.

[0042] The external cleaning component 41 includes an outer tube 411 and several external nozzles 412. The outer tube 411 is horizontally fixed to the opposite side of the limiting plate 2 and extends along the length of the limiting plate 2. One end of the outer tube 411 is connected to a water source. According to actual needs, multiple outer tubes 411 can be spaced apart in the height direction. The external nozzles 412 are spaced apart on the outer tube 411, and each external nozzle 412 faces another limiting plate 2. The installation orientation of each external nozzle 412 can be different to thoroughly rinse different parts of the outside of the product.

[0043] The inner cleaning component 42 includes an inner tube 421 and several inner nozzles 422. The inner tube 421 is located above the conveyor belt 1 and is arranged along the conveying direction of the conveyor belt 1. The inner nozzles 422 are installed on the outside of the inner tube 421 and are arranged around the outer periphery of the inner tube 421. The inner nozzles 422 face different directions around the periphery of the inner tube 421, and each inner nozzle 422 is spaced apart along the length of the inner tube 421. The inner tube 421 includes a rigid part 4211 and a flexible part 4212 that are interconnected. The rigid part 4211 can be a plastic tube or a steel tube, and the flexible part 4212 can be a rubber tube. The end of the flexible part 4212 away from the rigid part 4211 can be connected to a water source. The rigid part 4211 ensures that the part of the inner tube 421 located directly above the conveyor belt 1 remains horizontal; therefore, when the product is placed on the conveyor belt 1, the rigid part 4211 can be inserted into the product.

[0044] In some embodiments, refer to Figure 2 and Figure 3 A movable part 6 and a driving assembly 7 are provided on the limiting plate 2. The movable part 6 is located outside the end of one of the limiting plates 2. The sliding direction of the movable part 6 is parallel to the sliding direction of the conveyor belt 1. The movable part 6 is slidably connected to the position directly above the outside of the conveyor belt 1. The driving assembly 7 is provided on the outside of the limiting plate 2 or the water collection tank 5. In this embodiment, the driving assembly 7 is provided on the outside of the water collection tank 5. The driving assembly 7 is also used to drive the movable part 6 to slide and adjust. A lifting block 8 is provided on the movable part 6. The lifting block 8 moves and adjusts along the height direction. The rigid part 4211 fixes the lifting block 8. A first adjusting member 9 is provided on the movable part 6 for driving the lifting block 8 to move and adjust. The first adjusting member 9 is selected as a vertically installed cylinder or electric cylinder.

[0045] When the product is conveyed forward to a position near the end of the conveyor belt 1, the inside and outside of the product have been cleaned. The first adjusting component 9 drives the lifting block 8 and the rigid tube to move upward until the upper side of the rigid tube abuts against the upper inner side of the product, lifting the product upward away from the conveying surface of the conveyor belt 1. Then, the driving component 7 drives the moving part and the rigid part 4211 to move away from the conveyor belt 1. The flexible part 4212 has a certain bending deformation capability to ensure that the rigid part 4211 can be adjusted synchronously with the moving lifting block 8 and the moving part 6. Until the product leaves the space between the two limiting plates 2 and directly above the conveyor belt 1, it is easy to remove the product from the rigid part 4211, reducing the obstruction of the limiting plates 2 and the top plate 3.

[0046] The drive assembly 7 includes a drive motor 71 and a guide rod 72 and a lead screw 73 horizontally disposed outside the limiting plate 2. The guide rod 72 and the lead screw 73 are parallel to the conveying direction of the conveyor belt 1. The lead screw 73 is rotatably disposed along its own axis. The drive motor 71 is a servo motor and is connected to the lead screw 73 for transmission. The moving part 6 is block-shaped. The guide rod 72 passes through the moving part 6, and the lead screw 73 also passes through the moving part 6 and is threadedly connected to the moving part 6. When the drive motor 71 drives the lead screw 73 to rotate, it can drive the moving part 6 to slide along the length direction of the guide rod 72.

[0047] In some embodiments, a rotating block 10 is rotatably connected to the moving part 6. The rotation axis of the rotating block 10 is horizontally arranged and perpendicular to the conveying direction of the conveyor belt 1. A second adjusting member 11 for driving the rotating block 10 to rotate is provided on the moving part 6. The second adjusting member 11 is also a servo motor and is drively connected to the rotating shaft of the rotating block 10. The rigid part 4211 is fixed to the rotating block 10. A collecting belt 12 is provided below the output end of the conveyor belt 1. The collecting belt 12 is located on one side of the lower end of the collecting trough 5. The collecting belt 12 is an existing conveyor belt and transports along the horizontal direction. The conveying direction of the collecting belt 12 is perpendicular to the conveying direction of the conveyor belt 1. When the rotating block 10 is plate-shaped and in a horizontal position, the inner tube 421 is also in a horizontal position.

[0048] When the moving part 6 brings the product and the rigid part 4211 to a position away from directly above the conveyor belt 1, the second adjusting member 11 drives the rotating block 10 to rotate downward on the side near the output end of the conveyor belt 1, thereby causing the inner tube 421 to tilt, and one end of the inner tube 421 to move downward toward the conveying surface of the collecting belt 12. Therefore, the product can slide directly onto the collecting belt 12 under its own weight and be transported to the required position by the collecting belt 12. Thus, there is no need for manual removal of the product from the inner tube 421, which is more convenient.

[0049] In some embodiments, refer to Figure 3 and Figure 4Several support columns 13 are fixed on the outside of the inner tube 421. The support columns 13 are perpendicular to the outside of the inner tube 421 and are fixed at intervals on the upper side of the inner tube 421. A ball bearing 14 is embedded and rolled at the upper end of the support column 13 away from the outside of the inner tube 421. The distance from the ball bearing 14 to the outside of the inner tube 421 is greater than the distance from the end of the nozzle to the outside of the inner tube 421, and the ball bearing 14 is close to the upper inner side of the product.

[0050] Because the cylindrical product may roll when the inner nozzle 422 sprays water onto the inner wall of the product, and because the support rod can be close to the upper inner side of the product when the inner diameter of the product is large, the support column 13 can play a certain limiting role, reducing the large range of rolling of the product during cleaning and conveying, and ensuring that the product can be stably conveyed forward along the conveyor belt 1. Furthermore, it can reduce the upward lifting distance of the lifting block 8 and reduce the mutual wear between the nozzle and the inner wall of the product. At the same time, the rolling friction between the ball bearing 14 and the inner side of the product reduces the range of angle of rotation of the rotating block 10, thus ensuring that the product slides smoothly from the outside of the inner tube 421.

[0051] In some embodiments, a threaded sleeve 15 is vertically fixed to the outside of the inner tube 421, and the end of the support column 13 near the inner tube 421 is threadedly connected to the threaded sleeve 15. Therefore, the position of the support column 13 in the threaded sleeve 15 can be adjusted to suit products with different inner diameters, ensuring that the end of the support column 13 with the ball 14 can be closer to the upper inner side of the product to better limit the product.

[0052] The implementation principle of the online cleaning device for CNC machine tools according to this application embodiment is as follows: During cleaning, the position of the support column 13 is adjusted according to the inner diameter of the product. Then, the product is placed horizontally on the conveyor belt 1, and the axial direction of the cylindrical product is aligned with the conveying direction of the conveyor belt 1. The product is fitted onto the rigid part 4211. At this time, the ball bearings 14 on the support column 13 are close to the upper inner side of the product, which can limit the large-scale rolling of the product during conveying and ensure greater stability during product cleaning. When the conveyor belt 1 conveys the product forward, the outer cleaning component 41 can rinse the outside of the product, while the rigid part 4211 and the inner nozzle 422 located inside the product can rinse the inside of the product, realizing effective cleaning of the internal parts of the cylindrical product and ensuring a comprehensive cleaning effect for the cylindrical product.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
