Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, and in particular to a horizontal drilling CNC machine tool for simultaneous multi-axis machining. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, and input them into the CNC device via an information carrier. After processing, the CNC device sends out various control signals to control the machine tool's movements, automatically machining parts according to the shape and dimensions required by the drawings. It can perform cutting operations on the workpiece shape and can perform operations such as grooving, drilling, reaming, boring, and polishing. The "multi-axis" in multi-axis CNC machine tools mainly refers to the number of axes that enable the spindle (or tool) to move independently in multiple directions, allowing for flexible machining of the workpiece and avoiding adjustments to the workpiece position and positioning operations.

[0003] Currently, the most precise multi-axis CNC machine tools are horizontal five-axis CNC machine tools. These machine tools mainly consist of the machine tool itself, a worktable for fixing and mounting the workpiece, a ram for mounting the spindle, and a moving system for driving the ram and worktable. The machine tool is the foundation of the entire machine tool, providing stable support for the entire machining process. The moving system includes three linear axes (X, Y, Z) and two rotary axes (A, B (or C), which respectively drive the horizontal rotation and linear motion of the worktable, the longitudinal and horizontal linear movement of the ram, and the rotational movement of the spindle. These axes can be linked and controlled, allowing the cutting tool to perform omnidirectional machining of the workpiece in three-dimensional space. The worktable has connecting holes for fixing the workpiece, which is stably fixed to the worktable using bolts or other methods for machining.

[0004] Multi-axis CNC machine tools are widely used in many industries and fields due to their high flexibility and machining accuracy, such as aerospace, automobile manufacturing, mold making, medical device manufacturing, and art and decoration production. However, when the cutting tool is machining the workpiece, it generates a large amount of metal chips. These metal chips are easily scattered in the machining space of the machine tool and can easily fall into the gaps in the equipment structure and the tracks of the moving system, which may affect the drive and motion structure of the equipment and cause the equipment to jam. Summary of the Invention

[0005] In order to effectively clean up debris and prevent it from affecting the normal operation of the equipment, this application provides a horizontal drilling CNC machine tool for simultaneous multi-axis machining.

[0006] The CNC machine tool for horizontal drilling and multi-axis simultaneous machining provided in this application adopts the following technical solution: A horizontal CNC machine tool for multi-axis simultaneous drilling includes a machine tool and a worktable. A support column is slidably mounted inside the machine tool, and the worktable rotates on the support column. The machine tool is equipped with a rotating column that drives the worktable to rotate, and the rotating column passes through the support column. A cleaning device for removing waste chips is provided on the worktable. The cleaning device includes a first dust-collecting plate and a second dust-collecting plate. Dust-collecting chambers are provided on the opposite sidewalls of the first and second dust-collecting plates. A first sliding hole and a second sliding hole are respectively opened at both ends of the worktable. The first and second dust-collecting plates are slidably connected to the first and second sliding holes, respectively. A dust-collecting pipe and a dust-collecting pump are provided inside the worktable. The dust-collecting chambers on the first and second dust-collecting plates are connected to the dust-collecting pump through the dust-collecting pipe. A collection component for filtering and collecting waste chips is provided at the front end of the dust-collecting pump. The cleaning device is equipped with an adjustment mechanism for adjusting the position of the first and second dust-collecting plates as the worktable rotates, preventing the cleaning device from obstructing the cutting tool's machining operation on the workpiece.

[0007] By adopting the above technical solution, when the equipment starts working, the dust pump starts synchronously. The waste generated on the workpiece is sucked into the dust suction pipe by the suction of the dust pump through the first or second dust suction plate. The waste is then filtered and collected by the collection component, thereby preventing the waste from falling into the machine tool at will, and reducing the possibility of metal fragments falling into the machine tool and affecting the operation of the equipment structure.

[0008] Preferably, the workbench has a placement slot, the control mechanism is disposed in the placement slot, the control mechanism includes a support block and a support rod, the support block is fixedly connected to the inner wall of the bottom of the placement slot, the middle part of the support rod is hinged to the top of the support block, and the support rod rotates around the support block as an axis. Both ends of the support rod are provided with sliding grooves, and sliders are slidably connected in the sliding grooves. The bottom ends of the first dust suction plate and the bottom ends of the second dust suction plate are respectively hinged to the sliders at both ends of the support rod. The control mechanism also includes a control component that can drive the support rod to rotate following the rotation angle of the worktable.

[0009] By adopting the above technical solution, when the worktable rotates, the control component drives the support rod to rotate vertically along the support block by the rotation angle of the worktable, thereby controlling the tilt angle of the support rod. When the support rod rotates and tilts, the first and second dust-collecting plates slide vertically against the inner walls of the first and second sliding holes. At this time, the hinge between the bottom end of the first and second dust-collecting plates and the slider rotates, and the slider slides along the slide groove following the tilt degree of the support rod. Thus, when the support rod rotates, the height of the first and second dust-collecting plates rises and falls, with the one closer to the tool lowering and the one farther away from the tool rising, thereby avoiding affecting the operation of the tool.

[0010] Preferably, the control component includes a first arc-shaped block and a second arc-shaped block, which are respectively fixedly connected to the support column and pass through the placement groove. The inner wall of the placement groove has an annular groove. The first arc-shaped block and the second arc-shaped block are arranged opposite each other and slide relative to each other in the annular groove. The height of the first arc-shaped block gradually increases from both ends to the middle, and the height of the second arc-shaped block gradually decreases from both ends to the middle. The two ends of the support rod abut against the first arc-shaped block and the second arc-shaped block, respectively.

[0011] By adopting the above technical solution, when the worktable rotates, the worktable rotates relative to the support column. The rotation of the worktable drives the support rod inside to rotate. When the support rod rotates, its two ends abut against the first arc block and the second arc block respectively, and gradually tilts according to the different heights of the first arc block and the second arc block, thereby adjusting the height of the first dust suction plate and the second dust suction plate.

[0012] Preferably, two return springs are provided in the placement groove. The two return springs are fixedly disposed on both sides of the support block, and the two ends of the return springs are fixedly connected to the support rod and the inner wall of the placement groove, respectively.

[0013] By adopting the above technical solution, the return spring has the function of supporting the support rod and limiting its position. At the same time, when the support rod is separated from the first arc block and the second arc block, it can not only reduce the shaking of the support rod, but also keep the support rod in a horizontal position.

[0014] Preferably, the collection assembly includes a collection box and a filter box. The filter box is installed in the placement slot, and the vacuum pipe is connected to the filter box. The collection box is installed at the bottom of the workbench, and the filter box and the collection box are connected in communication. The filter box is provided with a filter plate for isolating debris. The vacuum pump is fixedly installed in the placement slot and connected to the filter box. An exhaust pipe is connected to the end of the vacuum pump away from the filter box, and the exhaust pipe extends out of the placement slot.

[0015] By adopting the above technical solution, the debris and air sucked in by the first and second suction plates enter the filter box through the suction pipe. The debris is blocked by the filter plate and falls into the collection box, while the air is discharged from the exhaust pipe through the filter plate under the action of the suction pump.

[0016] Preferably, a plurality of balls are rotatably disposed on the side wall of the slider, and the balls roll on the inner wall of the groove.

[0017] By adopting the above technical solution, when the support rod tilts, the slider slides in the groove. The ball bearings can reduce the friction between the slider and the groove, reduce the difficulty of the slider sliding, and thus reduce the possibility that the support rod may get stuck and unable to rotate due to the slider's difficulty in sliding.

[0018] Preferably, the workbench has multiple collection slots, the bottoms of the multiple collection slots are interconnected and connected to the filter box through a dust suction pipe; multiple scrapers are rotatably arranged on the surface of the workbench, and the scrapers slide on the surface of the workbench.

[0019] By adopting the above technical solution, when the cleaning device collects debris, some debris may fall onto the worktable and be blocked by the workpiece, which may cause the dust to be not cleaned thoroughly. Therefore, when the cleaning device is started, suction will be generated in the collection gap at the same time, and the scraper sliding on the worktable surface can push the debris that falls onto the worktable into the collection gap, thereby strengthening the cleaning intensity of the debris.

[0020] Preferably, a collection rail is fixedly connected to the side wall of the workbench, and a cleaning door is provided on the side wall of the collection rail.

[0021] By adopting the above technical solution, the collection bin can reduce the possibility of debris falling from the workbench onto the machine tool. When there is too much debris in the collection bin, the staff can open the cleaning door and use tools to clean out the debris from its inner wall.

[0022] Preferably, the scraper includes a straight rod and multiple hinged rods, the multiple hinged rods are connected in sequence by hinges and one end of the hinge is connected to the straight rod by hinges. A torsion spring for resetting is provided at the hinge. A rotating rod is fixedly connected to the end of the straight rod away from the hinged rod. The rotating rod rotates on the worktable. A miniature motor for driving the rotating rod to rotate is provided on the collection column.

[0023] By adopting the above technical solution, the motor drives the rotating rod to rotate, and the rotating rod drives the scraper to rotate. If the end of the rotating rod away from the rotating rod touches the workpiece or cleaning device, the hinge rod will rotate and fold under its obstruction. When it moves away from the obstruction, the hinge rod will return to its original position under the action of the torsion spring.

[0024] In summary, this application includes at least one of the following beneficial technical effects: When the equipment starts working, the dust pump starts simultaneously. The waste generated on the workpiece is sucked into the dust pipe by the suction of the dust pump through the first or second dust suction plate. The waste is then filtered and collected by the collection component, thereby preventing the waste from falling into the machine tool at will, and reducing the possibility of metal fragments falling into the machine tool and affecting the operation of the equipment structure. When the worktable rotates, the control component drives the support rod to rotate vertically via the rotation angle of the worktable, thereby controlling the tilt angle of the support rod. When the support rod rotates and tilts, the first and second dust-collecting plates slide vertically against the inner walls of the first and second sliding holes. At this time, the hinge between the bottom end of the first and second dust-collecting plates and the slider rotates, and the slider slides along the slide groove following the tilt of the support rod. Thus, when the support rod rotates, the height of the first and second dust-collecting plates rises and falls, with the plate closer to the tool lowering and the plate further away from the tool rising, thereby avoiding affecting the operation of the tool. When the worktable rotates, it rotates relative to the support column. The rotation of the worktable causes the support rod inside to rotate. When the support rod rotates, its two ends abut against the first arc block and the second arc block respectively. As the height of the first arc block and the second arc block are different, the support rod gradually tilts, thereby adjusting the height of the first and second dust suction plates.

[0032] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. Example

[0033] Embodiment 1 of this application discloses a horizontal drilling CNC machine tool for simultaneous multi-axis machining, such as... Figure 1 and Figure 2 As shown, the main components include a machine tool 1, a worktable 2, a spindle box, a five-axis transmission system, a CNC system, a tool magazine and tool changer, and protective devices. A support column 3, cylindrical in shape, slides horizontally within the machine tool 1 and is vertically positioned. The worktable 2 is located on top of the support column 3 and is rotatably mounted on it. A rotating column 41 for driving the worktable 2 is also provided on the machine tool 1. A cavity is formed within the support column 3, and the rotating column 41 rotates within this cavity. The top of the rotating column 41 is vertically positioned and its top end is fixedly welded to the worktable 2. The worktable 2 is cylindrical with a diameter larger than that of the support column 3. Multiple fixing holes for securing workpieces are located at the center of the upper surface of the worktable 2. The workbench 2 is equipped with a cleaning device 42 for removing waste debris. The cleaning device 42 includes a first suction plate 4 and a second suction plate 5, both of which are arc-shaped. Suction chambers 6 are provided on the opposite sidewalls of the first and second suction plates 4 and 5 to clean the debris generated during processing on the workbench 2. A first sliding hole 7 and a second sliding hole 8 are respectively formed at both ends of the upper surface of the workbench 2 in the vertical direction. The first suction plate 4 and the second suction plate 5 are slidably connected to the inner walls of the first sliding hole 7 and the second sliding hole 8 in the vertical direction, respectively.

[0034] like Figure 2 and Figure 3As shown, the workbench 2 is equipped with a suction pipe 9 and a suction pump 10. A placement groove 13 is formed within the workbench 2. The first sliding hole 7 and the second sliding hole 8 are both connected to the placement groove 13. The rotating column 41 includes an upper column 37 and a lower column 38, both cylindrical and coaxially arranged, and are welded together. The upper column 37 of the rotating column 41 passes through the bottom inner wall of the placement groove 13 and is fixedly welded to the workbench 2. The suction pump 10 is fixedly installed on the upper end face of the upper column 37 within the placement groove 13. The suction chambers 6 on the first suction plate 4 and the second suction plate 5 are both connected to the suction pump 10 via the suction pipe 9. A collection assembly 11 for filtering and collecting waste is provided at the front end of the suction pump 10. The collection assembly 11 is placed on the upper end face of the upper column 37. When the rotating column 41 drives the workbench 2 to rotate, the internal suction pump 10 and collection assembly 11 move synchronously.

[0035] like Figure 2 and Figure 3 As shown, the collection assembly 11 includes a collection box 22 and a filter box 23. The filter box 23 is installed on the upper end face of the upper column 37 in the placement slot 13. The suction pipe 9 is connected to the filter box 23. The collection box 22 is installed on the lower end face of the upper column 37. The filter box 23 and the collection box 22 are connected. The bottom of the collection box 22 is provided with a sealing door 43. The sealing door 43 is provided with a switch for controlling its opening and closing, so as to facilitate the cleaning of metal shavings inside. The filter box 23 is provided with a filter plate 25 for isolating debris. The debris separated by the filter plate 25 falls into the collection box 22. The suction pump 10 is fixedly installed in the placement slot 13 and connected to the filter box 23. The end of the suction pump 10 away from the filter box 23 is connected to an exhaust pipe 26. The exhaust pipe 26 extends out of the placement slot 13. The side wall of the cavity of the support column 3 is provided with an air outlet window 39 for the exchange of internal and external airflow and for workers to clean debris in the collection box 22. The workbench 2 is equipped with a control mechanism 12 for adjusting the position of the first dust suction plate 4 and the second dust suction plate 5 as the workbench 2 rotates, so as to prevent the cleaning device 42 from obstructing the cutting tool 40 from processing the workpiece.

[0036] like Figure 2As shown, the control mechanism 12 is disposed in the placement groove 13. The control mechanism 12 includes a support block 14 and a support rod 15. The support block 14 is trapezoidal in shape and its bottom is fixedly welded to the upper end face of the upper column 37. The top of the support block 14 is fixedly welded to the top inner wall of the placement groove 13, thereby driving the worktable 2 to rotate. The support rod 15 is cuboid in shape and is hinged to the support block 14 at its center point along its length. The support rod 15 rotates around the support block 14 with the support block 14 as the axis. Both ends of the support rod 15 are provided with sliding grooves 16 along its length. The sliding grooves 16 are dovetail grooves. A slider 17 is slidably connected in the sliding grooves 16. The slider 17 is also dovetail shaped. Multiple balls 27 are rotatably disposed on the side wall of the slider 17. The balls 27 are tumbled and connected to the inner wall of the sliding groove 16. The balls 27 can reduce the friction between the slider 17 and the inner wall of the sliding groove 16, making the slider 17 more flexible. The bottom ends of the first dust suction plate 4 and the second dust suction plate 5 are respectively hinged to the sliders 17 at both ends of the support rod 15. The control mechanism 12 also includes a control component 18 that can drive the support rod 15 to rotate following the rotation angle of the workbench 2.

[0037] like Figure 2 and Figure 3 As shown, the control component 18 includes a first arc-shaped block 19 and a second arc-shaped block 20. The first arc-shaped block 19 and the second arc-shaped block 20 are respectively fixedly welded to the upper end face of the support column 3. An annular groove is opened on the inner wall of the bottom of the placement groove 13. The first arc-shaped block 19 and the second arc-shaped block 20 pass through and slide relative to each other in the annular groove. The first arc-shaped block 19 and the second arc-shaped block 20 are arranged opposite each other. The height of the first arc-shaped block 19 gradually increases from both ends to the middle, and the height of the second arc-shaped block 20 gradually decreases from both ends to the middle. The two ends of the support rod 15 abut against the top of the first arc-shaped block 19 and the top of the second arc-shaped block 20, respectively. Both sides of the support block 14 are provided with a return spring 21 in the vertical direction. The two ends of the return spring 21 are fixedly welded to the lower end face of the support rod 15 and the upper surface of the upper column 37, respectively. The return spring 21 provides support for the support rod 15 and limits its position. At the same time, when the support rod 15 is separated from the first arc block 19 and the second arc block 20, it can not only reduce the shaking of the support rod 15, but also keep the support rod 15 in a horizontal position.

[0038] The implementation principle of Embodiment 1 of this application is as follows: When the equipment starts working, the dust pump 10 starts synchronously. The waste generated on the workpiece is sucked into the dust pipe 9 by the suction of the dust pump 10 through the first dust suction plate 4 or the second dust suction plate 5. The dust is separated by the filter box 23 and the separated dust falls into the collection box 22. The separated air is discharged from the exhaust pipe 26 through the filter plate 25, thereby filtering and collecting the waste, thus preventing the waste from falling into the machine tool 1 at will, thereby reducing the possibility of metal fragments falling into the machine tool 1 and affecting the operation of the equipment structure. When the worktable 2 rotates according to processing needs, the rotating column 41 drives the worktable 2 to rotate relative to the support column 3. The rotation of the rotating column 41 drives the support rod 15, the collection component 11, etc. on it to rotate synchronously. When the support rod 15 rotates, its two ends slide relative to the first arc block 19 and the second arc block 20 respectively, and gradually follow the height difference between the first arc block 19 and the second arc block, so that the support rod 15 gradually tilts, thereby adjusting the height of the first dust suction plate 4 and the second dust suction plate 5. For example, when the worktable 2 rotates, the first dust suction plate 4 gradually moves closer to the tool 40, and the first dust suction plate 4 gradually moves downward in the vertical direction along the first sliding hole 7 until it is in the placement groove 13. When the second dust suction plate 5 gradually moves away from the tool 40, the second dust suction plate 5 moves upward in the vertical direction along the second sliding hole 8, thereby avoiding the cleaning device 42 from obstructing the tool 40's processing operation on the workpiece. Example

[0039] like Figure 4 and Figure 5 As shown, and in combination Figure 6 As shown, the difference between this embodiment 2 and embodiment 1 is that: multiple collection slots 28 are provided on the workbench 2, the bottoms of the multiple collection slots 28 are interconnected and connected to the filter box 23 through the suction pipe 9, and a collection rail 30 is fixedly welded to the side wall of the workbench 2, with a cleaning door 31 provided on the side wall of the collection rail 30. Multiple scraper rods 29 are rotatably arranged on the surface of the workbench 2, and the scraper rods 29 slide on the surface of the workbench 2. A micro motor 36 is fixedly installed inside the collection rail 30, and a rotating rod 35 is welded vertically to the shaft of the micro motor 36. The scraper rod 29 is fixedly welded to the top of the straight rod 32. The scraper rod 29 includes the straight rod 32 and multiple hinge rods 33, which are connected in sequence by hinges, and one end of each hinge rod is connected to the straight rod 32 by hinge. A torsion spring 34 for reset is provided at each hinge point, and the hinge rod 33 is located at the end of the straight rod 32 away from the rotating rod 35.

[0040] The implementation principle of Embodiment 2 of this application is as follows: When the cleaning device 42 collects debris, some debris may fall onto the workbench 2 and be blocked by the workpiece, making it difficult to be cleaned by the first suction plate 4 or the second suction plate 5, resulting in incomplete cleaning. Therefore, when the cleaning device 42 is started, suction will be generated in the collection gap 28. At the same time, the micro motor 36 is started, and the scraper 29 slides backward on the surface of the workbench under the drive of the micro motor 36, pushing the debris on the surface of the workbench 2 into the collection gap 28, thereby strengthening the cleaning intensity of the debris. If the hinge rod 33 at the end away from the rotating rod 35 encounters the workpiece, the hinge rod 33 will rotate and fold under its obstruction. When it moves away from the obstruction, the hinge rod 33 will return to its original position under the action of the torsion spring 34.

[0041] In addition, the collection bin 30 can reduce the possibility of debris falling from the workbench 2 onto the machine tool 1. When there is too much debris in the collection bin 30, the staff can open the cleaning door 31 and clean out the debris from its inner wall with tools.

[0042] 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.
