Description

Technical Field

[0001] This invention relates to the field of CNC machine tool technology, and in particular to a CNC milling machine for aluminum with a follow-up chip removal function. Background Technology

[0002] A CNC milling machine is a device used to process workpieces. During the processing of aluminum workpieces on a CNC machine tool, cutting and other processing steps will generate chips, which need to be cleaned to avoid affecting the processing accuracy of the CNC milling machine.

[0003] Patent CN215547127U discloses a chip removal device for CNC machine tools. The chip removal device includes a machine tool body and an air pump. A machining table is installed on the top of the machine tool body, and a fixing block is fixed on the top of the machining table. A threaded rod is connected to the surface of the fixing block, and an extrusion plate is installed on the inner side of the threaded rod. A slot is provided between the machining table and the inner side of the machine tool body, and a collection frame is provided on the slot. Air pumps are installed on the left and right sides of the machine tool body. An air guide pipe is installed on the surface of the air collection pipe, and protective nets are installed at both ends of the inner side of the machine tool body. A cylinder is installed on the top of the machine tool body.

[0004] This chip removal device uses an air pump to draw air into a collection frame for collection. However, when CNC machine tools process metal workpieces, the cutting head moves to change the cutting position for finishing. Since the air suction position of this chip removal device remains unchanged, it cannot follow the cutting head in real time and cannot effectively remove chips from the cutting head, affecting the machining accuracy of aluminum workpieces. Therefore, we propose an aluminum CNC milling machine with a real-time chip removal function that can follow the cutting head movement for collection and cleaning. Summary of the Invention

[0005] In order to overcome the shortcomings of existing chip removal devices that have a fixed air intake position and cannot perform real-time follow-up collection, this invention provides an aluminum CNC milling machine with a follow-up chip removal function that can follow the movement of the cutting head for real-time collection and cleaning.

[0006] The technical implementation of the present invention is as follows: A CNC milling machine for aluminum materials with a following chip removal function includes a machine tool, a mounting frame fixedly connected inside the machine tool, a first sliding plate symmetrically and slidably connected inside the mounting frame via a sliding groove, a collection frame for collecting chips fixedly connected between the first sliding plates, and a vertical plate fixedly connected to the collection frame.

The extension plate and the fixing frame are pressed together. A third spring is fixedly connected between the fixing frame and the first baffle.

[0010] More preferably, it also includes a cleaning assembly for cleaning the first baffle and the extension plate. The cleaning assembly is disposed on the first baffle and includes a guide rod, which is fixedly connected to the side of the first baffle near the collection frame. A second sliding plate is slidably connected to the guide rod. A rotating plate is rotatably connected to the side of the first baffle near the guide rod. The second sliding plate and the rotating plate are pressed together. A second torsion spring is fixedly connected between the rotating plate and the first baffle. A telescopic rod is fixedly connected to the side of the first baffle away from the guide rod. A crossbar is fixedly connected to the extended end of the telescopic rod. A cleaning brush is slidably connected to the crossbar. The rotating plate is sleeved on the side of the cleaning brush near the crossbar.

[0011] More preferably, it also includes a pusher assembly for pushing out the debris collected in the collection frame. The pusher assembly is disposed in the collection frame and includes a guide shaft. The guide shaft is rotatably connected to the side of the collection frame away from the vertical plate. The collection frame is slidably connected to a pusher plate via a guide rail. The pusher plate and the guide shaft are slidably connected via a slant groove. A gear is fixedly connected to the side of the guide shaft away from the air jet plate. A sliding rod is slidably connected to the side of the collection frame near the gear. A fourth spring is fixedly connected between the sliding rod and the collection frame. A rack is fixedly connected to the sliding rod. The rack meshes with the gear and is pressed against the inner wall of the mounting frame.

[0012] More preferably, it also includes a pressing assembly for intermittently pressing the second sliding plate. The pressing assembly is disposed in the mounting frame and includes a strip plate. The strip plate is fixedly connected to the side of the mounting frame away from the convex strip plate. The strip plate is fixedly connected to equidistantly distributed mounting blocks. The mounting blocks are slidably connected to a slide rod. The side of the slide rod away from the mounting block is fixedly connected to a contact block. The second sliding plate is pressed and engaged with the contact block. A fifth spring is fixedly connected between the contact block and the adjacent mounting block.

[0013] More preferably, the contact block is provided with mutually symmetrical inclined surfaces to achieve the compression of the second sliding plate.

[0014] More preferably, it also includes a guiding assembly for guiding and discharging debris. The guiding assembly is disposed between the mounting frame and the collecting frame. The guiding assembly includes a guiding plate, which is fixedly connected to the side of the mounting frame away from the convex plate.

[0015] More preferably, the guide plate is inclined on the side near the convex plate to guide the debris.

[0016] The present invention has the following advantages: 1. The clamping plate is clamped on the cutter head of the machine tool. When the cutter head processes the workpiece, the debris generated will fall into the collection frame for collection. When the cutter head moves left and right, the clamping plate drives the collection frame to move left and right through the sliding frame and the vertical plate, so that the collection frame follows the movement of the cutter head for real-time collection.

[0017] 2. The airbag and the convex plate work together to make the air jet plate continuously blow air to clean the cutter head and workpiece. The air jet plate can also clean the cutter head and workpiece in real time by moving with the collection frame.

[0018] 3. When the sliding frame moves with the cutter head, the entire shielding assembly also moves with the cutter head. The first baffle and the extension plate shield the debris splashed from the cutter head to prevent the debris from scattering and ensure that the debris falls into the collection box for collection.

[0019] 4. The second sliding plate and the rotating plate work together to control the cleaning brush to move to the left. The cleaning brush cleans the debris adhering to the back of the first baffle and the extension plate, so that the staff can check the workpiece processing status through the first baffle and the extension plate.

[0020] 5. When the collection box moves to the left side of the machine tool, the workpiece is processed. The guide shaft rotates to control the pusher plate to slide forward, automatically pushing all the debris collected in the collection box forward.

[0021] 6. The second sliding plate, in conjunction with the contact block, enables the cleaning brush to automatically and intermittently clean the back of the first baffle and the extension plate.

[0022] 7. The second baffle blocks the lower front part of the collection frame to prevent debris from leaking out of the collection frame when it moves. When the pusher plate pushes out the debris, the guide plate can guide the debris so that the debris is discharged through the square groove. Attached Figure Description

Detailed Implementation

[0042] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0043] Example 1: A CNC milling machine for aluminum materials with a following chip removal function, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the machine tool includes a machine tool 1, a mounting frame 101, a first sliding plate 2, a collecting frame 3, a vertical plate 4, a sliding frame 5, a clamping plate 6, a first spring 7, an air jet assembly, and a shielding assembly. The mounting frame 101 is fixedly connected to the lower part of the machine tool 1. A square groove is opened on the left side of the front side of the mounting frame 101. The first sliding plate 2 is slidably connected to both the front and rear parts of the mounting frame 101 through sliding grooves. The collecting frame 3 is fixedly connected between the front and rear first sliding plates 2. The collecting frame 3 can collect debris. The vertical plate 4 is slidably connected to the right side of the collecting frame 3. The sliding frame 5 is slidably connected to the upper side of the vertical plate 4. The clamping plate 6 is symmetrically slidably connected to the upper part of the sliding frame 5. The clamping plate 6 can clamp the cutting head and drive the collecting frame 3 to move with the cutting head for real-time collection. The first spring 7 is fixedly connected between the clamping plate 6 and the sliding frame 5. An air jet assembly is provided between the machine tool 1 and the collecting frame 3. The air jet assembly can blow away debris from the cutting head and aluminum workpiece. A shielding assembly is provided on the sliding frame 5. The shielding assembly can prevent debris from splashing.

[0044] When using the device, the operator controls the clamping plate 6 to slide open in opposite directions on the sliding frame 5, causing the first spring 7 to deform. Then, the two clamping plates 6 are moved to the front and rear sides of the cutter head on the machine tool 1. The clamping plates 6 are then released, and under the action of the first spring 7, the clamping plates 6 slide back to clamp the cutter head. During the processing of aluminum workpieces, the chips generated by the cutter head will fall into the collection frame 3 for collection. The air jet component can blow off the chips adhering to the cutter head and aluminum workpiece for cleaning, so that the collection frame 3 can collect them. The shielding component can shield the chips to prevent them from splashing. When the cutter head moves left and right, the clamping plate 6, the sliding frame 5 and the vertical plate 4 will drive the collection frame 3 to move left or right, so that the collection frame 3 can follow the movement of the cutter head for real-time collection. When the cutter head moves up and down or back and forth, since the vertical plate 4 can slide back and forth on the collection frame 3 and the sliding frame 5 can slide up and down on the vertical plate 4, it will not affect the normal movement for fine processing.

[0045] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the jet assembly includes a raised strip plate 8, a jet plate 9, a connecting frame 10, an air outlet pipe 11, an airbag 12, an air inlet pipe 13, and an arc-shaped plate 14. The raised strip plate 8 is fixedly connected to the upper rear side of the mounting frame 101, the jet plate 9 is fixedly connected to the upper rear side of the collection frame 3, the connecting frame 10 is fixedly connected to the upper rear side of the jet plate 9, the air outlet pipe 11 with a one-way valve is connected to the middle rear side of the connecting frame 10, the airbag 12 is fixedly connected to the rear side of the air outlet pipe 11, the airbag 12 moves to the left and is squeezed by the raised strip plate 8, the upper side of the airbag 12 is connected to the air inlet pipe 13 with a one-way valve, and the arc-shaped plate 14 is fixedly connected to the air outlet pipe 11, the arc-shaped plate 14 is attached to the front side of the airbag 12.

[0046] Because debris easily adheres to the cutting head and the aluminum workpiece during processing, affecting the precision machining of the aluminum workpiece, it is necessary to blow off the debris adhering to the cutting head and the aluminum workpiece. The specific operation is as follows: When the collection frame 3 slides to the left, it will drive the air jet plate 9, the connecting frame 10, the air outlet pipe 11 and the air bag 12 to move to the left. When the air bag 12 moves to the left and contacts the convex plate 8, the air bag 12 will be squeezed and contracted by the convex plate 8. Because the arc plate 14 lifts the front of the air bag 12, it can ensure that the air bag 12 Due to the compression effect, when the airbag 12 is squeezed and contracted, the air inside the airbag 12 enters the connecting frame 10 through the air outlet pipe 11, and finally enters the jet plate 9. The air is sprayed out by the jet plate 9 to clean the cutter head and aluminum workpiece. When the airbag 12 moves to the left and disengages from the convex plate 8, the airbag 12 expands and resets, and draws in air through the air inlet pipe 13. When the airbag 12 moves to the left and is squeezed by the convex plate 8 again, the above action is repeated, so that the jet plate 9 continuously sprays air to clean the cutter head and aluminum workpiece in real time as it moves with the collection frame 3.

[0047] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the shielding assembly includes a vertical rod 15, a first baffle 16, a first torsion spring 17, and an extension assembly. The vertical rod 15 is fixedly connected to the front left side of the sliding frame 5. The first baffle 16 is rotatably connected to the vertical rod 15. The first torsion spring 17 is fixedly connected between the lower part of the first baffle 16 and the vertical rod 15. An extension assembly is provided on the first baffle 16, which can extend the shielding area.

[0048] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the extension assembly includes an extension plate 18, a second spring 19, a fixing frame 20, and a third spring 21. The extension plate 18 is slidably connected to the first baffle 16. The second spring 19 is fixedly connected between the extension plate 18 and the first baffle 16. The fixing frame 20 is slidably connected to the right side of the first baffle 16. The extension plate 18 slides to the right and contacts the fixing frame 20. The third spring 21 is fixedly connected between the upper and lower parts of the fixing frame 20 and the first baffle 16.

[0049] The cutting debris, combined with the agitation of the air jet assembly, easily scatters, so it's necessary to shield the scattering debris. The specific operation is as follows: When adjusting or changing the cutter head, the operator pushes the extension plate 18 to slide to the right on the first baffle 16. The second spring 19 deforms. When the extension plate 18 slides to the right until it contacts the fixing frame 20, the extension plate 18 continues to move to the right, pressing the fixing frame 20 forward. The third spring 21 deforms. When the extension plate 18 moves to the right and disengages from the fixing frame 20, the fixing frame 20 slides backward and resets under the action of the third spring 21, locking the right end of the extension plate 18, keeping the extension plate 18 in a retracted state. At this point, the operator can push the first baffle 16 forward on the vertical rod 15. When the first torsion spring 17 deforms, the first baffle 16 rotates forward and no longer blocks the front of the collection frame 3, allowing the operator to adjust the cutter head. After the cutter head is adjusted, the operator releases the first baffle 16. Under the action of the first torsion spring 17 resetting, the baffle rotates backward to reset. Then, the operator pushes the fixing frame 20 forward to slide and release the extension plate 18. Under the action of the second spring 19 resetting, the extension plate 18 slides to the left to expand the covering area. When the sliding frame 5 moves with the cutter head, the entire covering assembly also moves with the cutter head. The first baffle 16 and the extension plate 18 cover the debris splashed by the cutter head, preventing the debris from scattering and ensuring that the debris falls into the collection frame 3 for collection.

[0050] Example 2: Based on Example 1, such as Figure 2 , Figure 9 and Figure 10 As shown, it also includes a cleaning assembly, which can clean the first baffle 16 and the extension plate 18. The cleaning assembly is set on the first baffle 16 and includes a guide rod 22, a second sliding plate 23, a rotating plate 24, a second torsion spring 25, a telescopic rod 26, a crossbar 27, and a cleaning brush 28. The guide rod 22 is fixedly connected to the lower side of the first baffle 16, and the second sliding plate 23 is slidably connected to the guide rod 22. The rotating plate 24 is rotatably connected to the lower left corner of the rear side of the first baffle 16. The second sliding plate 23 slides to the right to press the rotating plate 24 to rotate. The second torsion spring 25 is fixedly connected between the rotating plate 24 and the first baffle 16. The telescopic rod 26 is fixedly connected to the upper rear side of the first baffle 16, and the extended end of the telescopic rod 26 is fixedly connected to the crossbar 27. The cleaning brush 28 is slidably connected to the crossbar 27, and the rotating plate 24 is sleeved on the upper part of the cleaning brush 28.

[0051] During the processing of aluminum workpieces, the operator needs to inspect the interior of machine tool 1. However, during cutting, the cooling water or oil used can cause debris to adhere to the back of the first baffle 16 and extension plate 18, obstructing the view. Therefore, it is necessary to clean the debris adhering to the first baffle 16 and extension plate 18. The specific operation is as follows: The operator pushes the second sliding plate 23 to slide to the right on the guide rod 22. The rightward sliding of the second sliding plate 23 pushes the rotating plate 24 to rotate, causing the second torsion spring 25 to deform. The rotation of the rotating plate 24 drives the cleaning brush 28 to slide to the left on the crossbar 27, thus cleaning the back of the first baffle 16 first. When the cleaning brush 28 slides to the leftmost end of the crossbar 27, the continued rotation of the rotating plate 24 will drive the cleaning brush 28 to continue moving to the left, thus cleaning the back of the first baffle 16. 27 will also move to the left, causing the telescopic rod 26 to extend. The cleaning brush 28 continues to move to the left to clean the rear side of the extension plate 18. After cleaning, the operator releases the second sliding plate 23. Under the action of the second torsion spring 25 resetting, the rotating plate 24 reverses and pushes the second sliding plate 23 to slide to the left to reset. While the rotating plate 24 reverses, it drives the cleaning brush 28 to slide to the right on the crossbar 27. When the cleaning brush 28 slides to the rightmost end of the crossbar 27, the cleaning brush 28 continues to move to the right and will drive the telescopic rod 26 to shorten and reset through the crossbar 27. In this way, the debris adhering to the rear side of the first baffle 16 and the extension plate 18 can be cleaned so that the operator can check the processing status of the aluminum workpiece through the first baffle 16 and the extension plate 18.

[0052] like Figure 1 , Figure 11 , Figure 12 and Figure 13 As shown, it also includes a pushing assembly, which can push out the debris collected in the collection frame 3. The pushing assembly is set on the collection frame 3 and includes a guide shaft 29, a pushing plate 30, a gear 31, a sliding rod 32, a fourth spring 33, and a rack 34. The guide shaft 29 is rotatably connected to the left side of the collection frame 3. The pushing plate 30 is slidably connected to the collection frame 3 through a guide rail. The pushing plate 30 and the guide shaft 29 are slidably connected through an inclined groove. The gear 31 is fixedly connected to the front of the guide shaft 29. The sliding rod 32 is slidably connected to the front left side of the collection frame 3. The fourth spring 33 is fixedly connected between the sliding rod 32 and the collection frame 3. The rack 34 is fixedly connected to the sliding rod 32. The rack 34 meshes with the gear 31. The rack 34 moves to the left and contacts the inner wall of the mounting frame 101.

[0053] When using this device, the collection frame 3 slides to the left, which in turn drives the rack 34 to move to the left via the sliding rod 32. When the rack 34 moves to the left and contacts the inner left side of the mounting frame 101, it is restricted by the mounting frame 101 and stops moving to the left. If the collection frame 3 continues to move to the left, it will slide to the left on the sliding rod 32, causing the fourth spring 33 to deform. As the collection frame 3 continues to move to the left, it also drives the gear 31 to move to the left via the guide shaft 29. The gear 31 moves to the left and meshes with the rack 34, causing it to rotate. The rotation of the gear 31 drives the guide shaft 29 to rotate. The pusher plate 30 slides forward, pushing all the debris collected in the collection frame 3 forward. When the collection frame 3 slides to the right to reset, the sliding rod 32 drives the rack 34 to move to the left to reset under the action of the fourth spring 33. The rack 34 moves to the left to reset, causing the gear 31 to reverse. The reverse rotation of the gear 31 causes the guide shaft 29 to reverse, and the reverse rotation of the guide shaft 29 causes the pusher plate 30 to slide backward to reset. In this way, after the cutter head moves to the left side of the machine tool 1 to complete the processing of the aluminum workpiece, all the debris collected in the collection frame 3 is automatically pushed forward.

[0054] like Figure 1 , Figure 2 , Figure 14 and Figure 15 As shown, it also includes a pressing assembly that can intermittently press the second sliding plate 23. The pressing assembly is mounted on the mounting frame 101 and includes a strip plate 35, mounting blocks 36, a slide rod 37, a contact block 38, and a fifth spring 39. The strip plate 35 is fixedly connected to the upper front part of the mounting frame 101. Five equally spaced mounting blocks 36 are fixedly connected to the strip plate 35. The slide rod 37 is slidably connected to the mounting block 36. The contact block 38 is fixedly connected to the rear end of the slide rod 37. The second sliding plate 23 slides to the left and contacts the contact block 38. The fifth spring 39 is fixedly connected between the contact block 38 and the adjacent mounting block 36.

[0055] When using the device, the guide rod 22 moves to the left, causing the second sliding plate 23 to move to the right. When the second sliding plate 23 moves to contact the contact block 38, its continued leftward movement is blocked by the contact block 38, causing the second sliding plate 23 to slide to the right on the guide rod 22. This, in turn, causes the cleaning brush 28 to move to the left to clean the debris adhering to the back of the first baffle 16 and the extension plate 18. When the second sliding plate 23 slides to its limit on the guide rod 22, its continued leftward movement will press against the contact block 38. The contact block 38 moves forward, causing the slide bar 37 to slide forward. The fifth spring 39 deforms. When the second sliding plate 23 moves to the left and disengages from the contact block 38, the slide bar 37 moves the contact block 38 backward to reset under the action of the fifth spring 39. The second sliding plate 23 also slides to the left on the guide rod 22 to reset. When the second sliding plate 23 moves to the left and contacts the next contact block 38, repeating the above actions will allow the cleaning brush 28 to automatically clean the rear side of the first baffle 16 and the extension plate 18 intermittently.

[0056] like Figure 16 , Figure 17 and Figure 18 As shown, it also includes a material guiding assembly, which can guide and discharge debris. The material guiding assembly is set between the mounting frame 101 and the collection frame 3. The material guiding assembly includes a material guiding plate 40, a guide rod 41, a second baffle 42, a sixth spring 43, and a contact plate 44. The material guiding plate 40 is fixedly connected to the front part of the mounting frame 101. The guide rods 41 are symmetrically connected to the left and right sides of the lower front part of the collection frame 3. The second baffle 42 is slidably connected between the two guide rods 41. The sixth spring 43 is fixedly connected between the second baffle 42 and the guide rod 41. The contact plate 44 is fixedly connected to the upper left side of the second baffle 42. The pusher plate 30 slides forward and contacts the contact plate 44.

[0057] In the initial state, the second baffle 42 blocks the lower front part of the collection frame 3 to prevent debris from leaking out during movement. When the pusher plate 30 slides forward to contact the contact plate 44, the pusher plate 30 continues to slide forward, pushing the contact plate 44 forward. The forward movement of the contact plate 44 causes the second baffle 42 to slide forward and open, causing the sixth spring 43 to deform. At this time, the debris pushed out by the pusher plate 30 will fall downward onto the guide plate 40 and be guided out of the square groove by the guide plate 40. When the pusher plate 30 slides backward and no longer squeezes the contact plate 44, under the action of the sixth spring 43 resetting, the second baffle 42 slides backward and resets to block the lower front part of the collection frame 3. In this way, the lower front part of the collection frame 3 can be blocked when the collection frame 3 moves to prevent debris from leaking out. When the pusher plate 30 pushes out the debris, it can guide the debris to ensure that the debris is discharged from the square groove.
