Description

Technical Field

[0001] This invention belongs to the field of machining centers, and more specifically, relates to a CNC horizontal machining center that prevents the accumulation of waste residue. Background Technology

[0002] A CNC horizontal machining center is an automated machining equipment that integrates mechanical, electronic, hydraulic, and pneumatic technologies. It is mainly used for multi-process machining of high-precision and complex parts, such as milling, drilling, boring, and tapping. Its core feature is that the spindle axis is parallel to the worktable plane (in a horizontal state). It is suitable for multi-face machining of parts such as box-shaped, disc-shaped, and plate-shaped parts, and has significant advantages, especially in batch production and machining of complex structural parts. Machining centers usually generate waste slag during the machining process. However, existing machining centers require manual handling of waste slag, which is inconvenient, time-consuming, and labor-intensive, leading to a decrease in work efficiency.

[0003] Chinese patent CN222095495U discloses a CNC horizontal machining center for preventing the accumulation of waste residue. The device uses a second motor to drive a screw conveyor shaft to rotate, which transports the waste residue into a connecting pipe and then into a collection box through a discharge pipe. The fixed seat is connected to the machining chamber through a connecting rod, which facilitates the falling of waste residue in the space between adjacent connecting rods, effectively preventing the accumulation of waste residue and avoiding manual cleaning, thus saving manpower. However, when cleaning waste residue, some of the waste residue may adhere to the inner wall of the device, resulting in poor cleaning effect.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The second ends of the multiple first rotating shafts extend into the mounting box. Among the multiple first rotating shafts on both sides of the mounting box, the multiple first rotating shafts on each side are arranged in pairs and connected by a belt drive mechanism. In the two pairs of first rotating shafts, one of them is fitted with and fixedly installed with a second bevel gear.

[0014] Multiple drive plates are fixedly installed on both sides of the spray pipe. Each drive plate is movably connected to a rack via a slide rod. A drive groove for the slide rod to move through the drive plate is provided. One end of the racks opposite to the drive plate passes through and is slidably disposed in the mounting box.

[0015] Multiple drive gears are rotatably mounted in the mounting box via a second rotating shaft. The multiple drive gears mesh with multiple racks respectively, and first bevel gears that mesh with multiple second bevel gears are sleeved and fixedly mounted on the multiple second rotating shafts.

[0016] Optionally, a sleeve rod is fitted on each of the first rotating shafts. The sleeve rod is fixedly installed between the mounting box and the connecting frame.

[0050] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0051] The invention will now be described in further detail with reference to the accompanying drawings.

[0052] Please see Figure 1-17 As shown, this embodiment provides a CNC horizontal machining center to prevent the accumulation of waste residue, including a device body 1, a machining equipment 2, a clamping mechanism 3, and a coolant spraying system 5. It also includes an inclined plate 6, which is fixedly installed inside the device body 1. The clamping mechanism 3 is fixedly installed on the inclined plate 6. A drain trough 12 is provided inside the device body 1. A drain port 10 is provided through the device body 1 between the inclined plate 6 and the drain trough 12. Two collection troughs 16 communicating with the drain trough 12 are provided opposite to each other inside the device body 1. A cleaning component 9 for cleaning the drain trough 12 is provided inside the device body 1. A connecting frame 19 is provided on the cleaning component 9. A spray pipe 13 is rotatably provided on the connecting frame 19. A reciprocating component 8 for driving the spray pipe 13 to reciprocate is provided on the device body 1. A sweeping component 23 for cleaning the drain trough 12 is provided on the connecting frame 19.

[0053] Specifically, the inclined plate 6 is fixed inside the device body 1 at a certain angle to the horizontal plane. The clamping mechanism 3 is installed on the inclined plate 6, so that the workpiece processing position is higher than the drain port 10. When the workpiece on the clamping mechanism 3 is processed by the processing equipment 2, the coolant spraying system 5 discharges coolant to spray and cool the workpiece. The waste residue and coolant generated during the processing slide down the surface of the inclined plate 6 to the drain port 10 under the action of gravity, and naturally fall into the drain trough 12 below. At this time, the drain trough 12 is cleaned by the cleaning component 9, and the waste residue in the drain trough 12 is discharged into the collection tank 16. At the same time, the waste residue is discharged through the spray pipe 1. 3. Connected to an external water supply pipeline, water is sprayed from the spray holes on the spray pipe 13 to rinse the inside of the sewage tank. At the same time, the reciprocating component 8 drives the spray pipe 13 to rotate back and forth, which increases the range of water flow from the spray pipe 13. The cleaning component 23 works in conjunction with the rotation of the spray pipe 13 to clean the inner wall of the sewage tank 12, improving the overall cleaning effect. The overall structure and operation steps are simple. The sewage tank 12 is automatically cleaned by the cooperation of the cleaning component 9, the cleaning component 23 and the reciprocating component 8, avoiding the accumulation of waste residue that affects the processing accuracy and equipment life, improving cleaning efficiency, and thus ensuring the normal use of the device.

[0054] It should be noted that in this embodiment, the design of the inclined plate 6 and the drain port 10 facilitates the automatic sliding of waste residue into the drain trough 12, avoiding accumulation in the processing area. The cleaning component 9 can automatically clean the drain trough 12, reducing the amount of manual cleaning work. The reciprocating rotation of the spray pipe 13 can spray the drain trough more comprehensively, improving the cooling and chip removal effect. Secondly, the coolant spray system 5 is set on the processing equipment 2. The structure, working method and installation position of the device body 1, processing equipment 2, clamping mechanism 3 and coolant spray system 5 are all existing technologies, and will not be described in detail here. Common types of clamping mechanisms include chucks, vises, special fixtures, etc., which clamp the workpiece by hydraulic, pneumatic or manual means to ensure no displacement during processing.

[0055] In this embodiment, as Figures 5 to 10As shown, the cleaning component 9 includes a slider 92, which is slidably disposed within the drain trough 12. The device body 1 is equipped with a moving mechanism 91 that drives the slider 92 to slide. A connecting frame 19 is fixedly mounted on the slider 92. A scraper 93 is fixedly mounted on the connecting frame 19 and is fitted against the bottom wall of the drain trough 12. Specifically, the connecting frame is fixedly mounted between the slider and the scraper. The moving mechanism 91 (such as a ball screw driven by a cylinder or servo motor) drives the slider 92 to perform reciprocating linear motion within the drain trough 12. The slider 92 drives the scraper 93 to move synchronously. The edge of the scraper 93 is tightly fitted against the inner wall of the drain trough 12 (the gap is typically ≤0.5mm). The waste residue deposited at the bottom of the tank is pushed to the collection tanks 16 on both sides, thereby realizing the automatic cleaning of the sewage discharge tank 12, ensuring the unobstructed flow of the sewage discharge tank 12, improving the automation level and chip removal efficiency of the machining center, and reducing the potential for failure caused by the accumulation of waste residue. It should be noted that the scraper 93 can be made of wear-resistant rubber or polyurethane material, which has both elasticity and rigidity, ensuring that it does not damage the surface while adhering to the tank wall. The two ends of the sewage discharge tank 12 are connected to the two collection tanks 16, so that the waste residue flows naturally into the collection tanks 16 under the push of the scraper 93. At the same time, the moving mechanism 91 can be linked with the control system of the machining center to automatically start the cleaning program during the processing interval, realizing unmanned operation.

[0056] In this embodiment, as Figures 5 to 16As shown, a mounting box 22 is fixedly installed between the slider 92 and the connecting frame 19. Multiple cleaning components 23 are included, each comprising multiple first rotating shafts 234 that pass through the spray pipe 13 and are rotatably mounted on both sides of the connecting frame 19. Each first rotating shaft 234 has a detachable cleaning brush 231 connected to its first end. The cleaning brush 231 abuts against the inner wall of the drain trough 12. The second ends of the multiple first rotating shafts 234 extend into the mounting box 22. On each side of the mounting box 22, multiple first rotating shafts 234 are arranged in pairs and connected by a belt drive mechanism 235. In each pair of first rotating shafts 234, a second bevel gear 237 is fitted and fixedly mounted. Multiple drive plates 232 are fixedly mounted on the spray pipe 19. On both sides, multiple drive plates 232 are movably connected to racks 233 via sliding rods. Drive slots 26 for sliding rod movement are provided through the drive plates 232. Multiple racks 233 are slidably disposed in the mounting box 22 with one end facing away from the drive plates 232. Multiple drive gears 238 are rotatably disposed in the mounting box 22 via second rotating shafts 239. Multiple drive gears 238 mesh with multiple racks 233 respectively. First bevel gears 236 meshing with multiple second bevel gears 237 are sleeved and fixedly installed on multiple second rotating shafts 239. Multiple first rotating shafts 234 are sleeved with sleeve rods 25. The sleeve rods 25 are fixedly installed between the mounting box 22 and the connecting frame 19. Multiple chip removal brushes 24 are fixedly installed in the mounting box 22 relative to the multiple racks 233. The chip removal brushes 24 abut against the racks 233.

[0057] Specifically, when the spray pipe 13 reciprocates under the drive of the reciprocating assembly 8, the drive plates 232 fixed on both sides of the spray pipe 13 rotate synchronously, causing the slide rod to slide in the drive groove 26, driving the rack 233 connected to it to perform linear reciprocating motion. One end of the rack 233 passes through the mounting box 22 and slides inside the box. Its direction of motion is related to the rotation direction of the spray pipe 13. The linear motion of the rack 233 drives the drive gear 238 meshing with it to rotate. The drive gear 238 drives the first bevel gear 236 to rotate synchronously through the second rotating shaft 239. The first bevel gear 236 drives the second bevel gear 237 to rotate. The second bevel gear 237 drives the first rotating shaft 234 to rotate. At the same time, the other first rotating shaft 234 paired with it is synchronously rotated through the belt transmission mechanism 235. The rotation of the first rotating shaft 234 drives the cleaning brush 231 at its bottom to rotate. The cleaning brush 231 abuts against the inner wall of the sewage tank 12, and cleans the tank wall. A comprehensive cleaning process is performed. The reciprocating rotation of the spray pipe 13, combined with the rotation of the cleaning brush 231, forms a composite motion trajectory, effectively removing stubborn waste residue. The chip removal brush 24 inside the mounting box 22 abuts against the rack 233, removing debris from its surface as the rack 233 reciprocates, preventing impurities from affecting the gear transmission accuracy. Simultaneously, the first rotating shaft 234 is rotatably mounted inside the sleeve 25, with a gap between the sleeve 25 and the first rotating shaft 234. The sleeve 25 protects the connection between the first rotating shaft 234 and the connecting frame 19 and the mounting box 22. The overall structure has simple operation steps and good linkage effect. Utilizing the movement of the spray pipe 13 as a power source, the automatic rotation of the cleaning brush 231 is achieved through mechanical transmission, eliminating the need for additional power equipment, reducing energy consumption and cost. The combination of the reciprocating rotation of the spray pipe 13 and the rotational movement of the cleaning brush 231 can cover all angles of the inner wall of the sewage tank 12, avoiding cleaning dead corners and improving the cleaning effect.

[0058] It should be noted that in this embodiment, there are eight first rotating shafts 234, and four shafts are rotatably arranged through each side of the connecting frame 19. The first rotating shafts 234 on both sides of the connecting frame 19 are arranged opposite to each other. The cleaning brush 231 is detachably arranged at the bottom of the first rotating shaft 234 (e.g., by bolt connection, snap-fit, etc.). The cleaning brush 231 and the first rotating shaft 234 are detachably connected, which facilitates the replacement of worn cleaning parts. At the same time, the cleaning brushes 231 on both sides are arranged opposite to each other along the scraper 93, and the eight first rotating shafts 234 extend into the mounting box 22 and are rotatably arranged on the mounting box 22. The mounting box 22 has four first rotating shafts 234 on each side. Among the four first rotating shafts 234 on each side, every two shafts are arranged in pairs, and the two first rotating shafts 234 in each pair are connected by a belt drive mechanism 235. The transmission connection is such that one of the two first rotating shafts 234 is fitted with and fixedly mounted a second bevel gear 237. The diameter of the second bevel gear 237 is smaller than the diameter of the first bevel gear 236. Meanwhile, the structure in which the rack 233 passes through and slides on the mounting box 22 is existing technology, for example, by sliding connection through a slider 92. Secondly, in this embodiment, both the support frame and the top two sides of the mounting box 22 have downward sloping surfaces to facilitate the removal of debris and dirt. Furthermore, the cleaning brush 231 can be made of hard nylon or steel wire, depending on the material of the inner wall of the drain trough 12 and the characteristics of the dirt. The bristles of the cleaning brush 231 are arranged to extend outward so that the bristles of the cleaning brush 231 can clean the corners of the drain trough 12, enhancing the adhesion to the trough wall and the cleaning power.

[0059] In this embodiment, as Figures 5 to 17As shown, the device body 1 has a mounting groove 20 for mounting the reciprocating assembly 8. The reciprocating assembly 8 includes a fixed plate 82, which is fixedly installed in the mounting groove 20. A wave-shaped movable groove 83 is provided through the fixed plate 82 along its length direction. A movable plate 81 is fixedly installed on the spray pipe 13. Two movable rods 84 are rotatably arranged on the movable plate 81. The two movable rods 84 are movably arranged in the movable groove 83. Specifically, when the moving mechanism 91 drives the slider 92 to make linear motion in the sewage tank 12, the connecting frame 19 moves synchronously with the slider 92. As the slider 92 moves, the movable rods 84 slide along the wave groove trajectory, forcing the movable plate 81 to drive the spray pipe 13 to make reciprocating rotation around the axis. Several spray holes are provided through the opposite two sides of the spray pipe 13. When the spray pipe 13 reciprocates, the coolant covers the inner wall of the sewage tank 12 in a fan-shaped area. The spraying angle dynamically changes with the rotation of the pipe. As the scraper 93 moves forward under the drive of the slider 92, the spray pipe 13 simultaneously sprays coolant to soften and wash away stubborn adhering waste residue. When the slider 92 returns, the spray pipe 13 rotates in the opposite direction, performing a secondary flush on the cleaned area to improve cleanliness. The coolant carries the waste residue through the drain trough 12 to the collection trough 16. The reciprocating rotation of the spray pipe 13 expands the coverage area of ​​the coolant, enhancing the cleaning effect on the drain trough 12 and improving cleaning efficiency. At the same time, the linear motion of the slider 92 is converted into the reciprocating rotation of the spray pipe 13 by the cooperation of the wave-shaped movable groove 83 and the movable rod 84. The structure is simple and reliable. The reciprocating rotation of the spray pipe 13 is achieved through a simple mechanical structure, eliminating the need for a complex drive device, reducing costs, and ensuring the cleanliness of the spray pipe 13. It can spray the sewage tank evenly; it should be noted that spray holes are provided on both sides of the spray pipe 13, and the spray pipe 13 is connected to the external water supply pipe (the structure of the external water supply equipment and the connection method with the spray pipe 13 are existing technologies and will not be described here).

[0060] In this embodiment, as Figure 17As shown, the distance between the two movable rods 84 is less than the length of each segment of the inclined movable track within the movable groove 83. Specifically, when the movable plate 81 moves, the two movable rods 84 on the movable plate 81 slide along the wavy track of the movable groove 83. Because the distance between the two movable rods 84 is less than the length of a single segment of the inclined track, the movable rods 84 are forcibly guided by the inclination angle of the track when sliding within the inclined track. When the movable rods 84 slide from one segment of the inclined track to another, due to the distance limitation, they will not cross two segments of the track simultaneously, but will slide sequentially within a single segment of the track, thereby causing the movable plate 81 to drive the spray pipe 13 to reciprocate at a predetermined angle. As the movable plate 81 continues to move, the movable rods 84 slide along the wavy track. The inclined track is continuously switched within the wavy track to achieve periodic reciprocating oscillation of the spray pipe 13, thereby ensuring that the movable rod 84 always slides within a single inclined track segment. This avoids the movable rod 84 from getting stuck at the junction of two track segments due to excessive spacing, preventing the spray pipe 13 from jamming or shaking during rotation, and ensuring a smooth and reliable rotation process. It should be noted that in this embodiment, the matching of the length of each inclined track segment of the wavy movable groove 83 with the spacing of the movable rod 84 strictly limits the rotation angle of the spray pipe 13 within the track design range. The length of each inclined track segment within the movable groove 83 is the same, and the angle of the inclined track within the movable groove 83 can be adjusted according to actual conditions, which will not be described here.

[0061] In this embodiment, as Figures 5 to 10 As shown, the spray pipe 13 extends into the mounting groove 20, and a movable groove 17 is provided through the device body 1 to allow the spray pipe 13 to move. Specifically, the spray pipe 13 extends into the mounting groove 20 and is movably connected through the movable groove 17. The movable groove 17 provides space for the spray pipe 13 to move, ensuring the normal operation of the cleaning component 9 in the drain trough 12, thereby better meeting the spraying needs of the machining center and improving the cooling and chip removal effect. It should be noted that in this embodiment, the height of the movable groove 17 in the drain trough 12 is higher than the height of the scraper in the drain trough 12. The advantage of this is that it can prevent the sewage in the drain trough 12 from being discharged into the mounting groove 20 along the movable groove 17.

[0062] In this embodiment, as Figures 5 to 15As shown, two guide plates 14 are fixedly installed relative to each other along the moving groove 17 inside the main body 1 of the device. A guide wheel 7 is sleeved on the spray pipe 13 and rotatably mounted between the two guide plates 14. The cross-section of the guide plate 14 is L-shaped along the extension direction of the guide plate 14. Specifically, when the spray pipe 13 moves, the guide wheel 7 contacts the guide plate 14, providing support and guidance for the movement of the spray pipe 13. Under the action of driving force, the spray pipe 13 moves along the moving groove 17, and the guide wheel 7 rolls in the L-shaped groove of the guide plate 14, restricting the spray pipe 13 to move only along the extension direction of the guide plate 14. When the spray pipe 13 needs to rotate, the guide wheel 7 rolls in the L-shaped groove formed by the two guide plates 14, simultaneously cooperating with the rotation requirements of the spray pipe 13 to achieve a composite motion of movement and rotation. During the entire working process of the machining center, the cooperation between the guide wheel 7 and the guide plate 14 improves the spray pipe's rotation efficiency. The stability of the spray pipe 13's movement is improved, reducing swaying and deviation, ensuring the accuracy of the spray pipe 13 during reciprocating rotation, and enhancing the flushing effect of the coolant. It should be noted that in this embodiment, the angle and size of the L-shaped guide plate 14 can be optimized and adjusted according to actual needs. For example, increasing the included angle of the L-shaped guide plate 14 can increase the activity space of the guide wheel 7, adapting to spray pipes 13 of different diameters. Adjusting the length of the guide plate 14 can change the travel of the spray pipe 13, meeting the needs of different processing scenarios. Secondly, the material selection of the guide plate 14 and the guide wheel 7 is crucial to their performance and service life. The guide plate 14 can be made of metal materials with high hardness and good wear resistance, such as stainless steel or hard alloy, to ensure that it is not easily worn during long-term use. The guide wheel 7 can adopt a structure of high-strength plastic or rubber wrapped around a metal wheel core, which can reduce the coefficient of friction while ensuring sufficient strength and wear resistance.

[0063] In this embodiment, as Figure 5 and Figure 6 As shown, an inclined baffle 11 is fixedly installed in the sewage trough 12 relative to the sewage outlet 10. Specifically, the baffle 11 is inclinedly installed in the sewage trough 12 and located at the opposite position to the sewage outlet 10. When waste slag flows into the sewage trough 12 with the coolant, the baffle 11 changes the direction of the fluid, so that the waste slag flows more concentratedly into the sewage trough 12. It should be noted that the baffle 11 does not contact the cleaning component 9, the sweeping component 23 and the spray pipe 13 to avoid conflict. Furthermore, the inclination angle of the baffle 11 can be adjusted according to the actual situation and is not limited here.

[0064] In this embodiment, as Figures 5 to 11As shown, each of the two collection tanks 16 is equipped with a detachable filter basket 15. A support frame 18 for mounting the filter basket 15 is fixedly installed in the collection tank 16. A drain pipe 4 connected to the collection tank 16 is fixedly installed on the main body of the device. Specifically, the filter basket 15 is detachably installed in the collection tank 16. The support frame 18 supports the weight of the filter basket 15. After the waste residue flows into the collection tank 16 with the coolant, the filter basket 15 intercepts the solid waste, and the coolant flows out through the filter basket 15. The filter basket 15 separates the waste residue from the coolant, which is convenient for subsequent processing. The detachable design makes it easier to clean and replace the filter basket 15 and reduces maintenance costs. The drain pipe 4 is connected to the collection tank 16 to discharge the filtered coolant out of the main body of the device. It should be noted that the main body is equipped with a maintenance compartment 21 and a maintenance door for maintaining the filter basket. This configuration is existing technology.

[0065] Working principle:

[0066] When the workpiece on the clamping mechanism 3 is processed by the processing equipment 2, the coolant spray system 5 discharges coolant to spray and cool the workpiece. During processing, the waste residue and coolant generated slide down the surface of the inclined plate 6 to the drain port 10 under gravity. At this time, the baffle 11 changes the fluid direction, causing the waste residue to flow more concentratedly towards the drain trough 12. Then, the sliding mechanism 91 (such as a ball screw driven by a cylinder or servo motor) drives the slider 92 to reciprocate linearly within the drain trough 12. The slider 92 drives the scraper 93 to move synchronously. The edge of the scraper 93 is in close contact with the inner wall of the drain trough 12 (the gap is usually ≤0.5mm), pushing the waste residue deposited at the bottom of the trough towards the collection tanks 16 on both sides. Simultaneously, when the sliding mechanism 91 drives the slider 92... When the sewage tank 12 moves in a straight line, the connecting frame 19 moves synchronously with the slider 92. As the slider 92 moves, the movable rod 84 slides along the wave groove trajectory, forcing the movable plate 81 to drive the spray pipe 13 to reciprocate around the axis. Several spray holes are provided through the opposite two sides of the spray pipe 13. When the spray pipe 13 reciprocates, the coolant covers the inner wall of the sewage tank 12 in a fan-shaped area, flushing away residual fine particles. The spray angle changes dynamically with the rotation of the pipe. When the scraper 93 is driven forward by the slider 92, the spray pipe 13 sprays coolant synchronously to soften and flush away stubbornly adhered waste residue. At the same time, when the spray pipe 13 reciprocates under the drive of the reciprocating assembly 8, the drive plates 232 fixed on both sides of the spray pipe 13 move with the reciprocating assembly 8. The synchronous rotation of the slide bar causes it to slide within the drive groove 26, driving the rack 233 connected to it to perform linear reciprocating motion. One end of the rack 233 passes through the mounting box 22 and slides within it. Its direction of motion is related to the rotation direction of the spray pipe 13. The linear motion of the rack 233 drives the drive gear 238 meshing with it to rotate. The drive gear 238 drives the first bevel gear 236 to rotate synchronously via the second rotating shaft 239. The first bevel gear 236 drives the second bevel gear 237 to rotate. The second bevel gear 237 drives the first rotating shaft 234 to rotate. Simultaneously, the belt drive mechanism 235 enables the other first rotating shaft 234 paired with it to rotate synchronously. The rotation of the first rotating shaft 234 drives the cleaning brush 231 at its bottom to rotate. The cleaning brush 231 and... The inner wall of the drain trough 12 is contacted, thoroughly cleaning the trough wall. The reciprocating rotation of the spray pipe 13, combined with the rotation of the cleaning brush 231, forms a compound motion trajectory, effectively removing stubborn waste residue. When the slider 92 returns, the spray pipe 13 rotates in the opposite direction, performing a second flush on the cleaned area to improve cleanliness. The coolant carries the waste residue through the drain trough 12 to the collection trough 16. After the waste residue flows into the collection trough 16 with the coolant, the filter basket 15 intercepts the solid waste, and the coolant flows out through the filter basket 15. The filter basket 15 separates the waste residue from the coolant. The overall structure and operation steps are simple. The cleaning component 9 automatically cleans the drain trough 12, avoiding the accumulation of waste residue that affects processing accuracy and equipment life, thereby ensuring the normal use of the device.
