Description

Technical Field

[0001] This invention relates to the field of chip removal technology for machine tools, specifically to a chip removal structure for a CNC composite machine tool for shaft machining. Background Technology

[0002] When producing shaft-type parts, machine tools are used to cut them. However, during the cutting process, a large amount of chips are generated. These chips remain inside the machine tool, affecting its production. Therefore, a chip removal mechanism is needed to remove the chips from inside the machine tool.

[0003] In actual use, the chip removal structure of existing CNC composite machine tools for shaft machining has a problem: when the chain plate conveys the chips, after the chips are detached from the chain plate, the chain plate continues to rotate. However, due to the viscosity of the coolant, chips may adhere to the surface of the chain plate. These chips can only be cleaned manually by stopping the machine, which makes the equipment extremely inconvenient to use. Summary of the Invention

[0009] As a preferred embodiment of the present invention: the number of sprockets is two, and the two sprockets are respectively located on the outer wall of the rotating shaft and the rotating rod, and the two sprockets are located on the inner wall of the chain.

[0010] As a preferred embodiment of the present invention: the number of the pushing cylinder and the cylinder controller is two, and the two pushing cylinders and the cylinder controller are symmetrically arranged on the top of the material collection chamber, and the two cylinder controllers are electrically connected.

[0013] As a preferred technical solution of the present invention: the number of the rack, fixing plate, limiting rod, spring two, sliding plate and insert is two, and the two racks, fixing plate, limiting rod, spring two, sliding plate and insert are diagonally arranged on the inner wall of the upright plate one.

[0014] As a preferred embodiment of the present invention: the lower pressure plate is located above the bearing component, and the shape of the lower pressure plate is adapted to the inner wall of the collection cavity.

[0015] The present invention has the following beneficial effects:

[0016] 1. The chip removal structure of this CNC composite machine tool for shaft machining works by starting motor one, which drives the rotating shaft and sprockets to rotate. Since the two sprockets are located inside the chain, they rotate simultaneously, which in turn causes the chain conveyor belt and magnetic column to rotate simultaneously. The magnetic column attracts the debris attached to the surface of the chain conveyor belt. At the same time, the rotation of the magnetic column causes the scraper to scrape off the debris from the surface of the magnetic column, so that the debris falls into the collection bin. Simultaneously, by rotating the lead screw, the lead screw nut and locking plate rotate, which separates the locking plate from the inside of the insertion plate, allowing the scraper to be removed and replaced.

[0017] 2. The chip removal structure of this shaft-type CNC composite machine tool works by starting motor two, which drives the drive shaft and worm gear to rotate. This causes the worm gear to rotate the worm wheel, which in turn rotates the rotating plate, closing the rotating plate and sealing the lower pressure plate. At this point, the push cylinder is activated, causing the entire extrusion plate assembly to move downwards, thus compressing the chips above the filter plate into blocks and squeezing out the coolant contained in the chips. Then, the gear is rotated, causing the gear to drive the two racks, sliding plate, and insert into the interior of the vertical plate. At this point, the fixed relationship of the bearing assembly disappears, allowing it to be pulled out. The chips above are compressed into blocks, resulting in less space occupied by the chips and easier transportation. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1-9A chip removal structure for a CNC composite machine tool for shaft machining includes a support frame 1. A chain conveyor belt 2 is rotatably connected to the inner wall of the support frame 1. A motor 3 is mounted on the outer wall of the support frame 1. A material collection chamber 4 is located at the bottom of the support frame 1. A rotating shaft 22 is mounted on the output shaft of the material collection chamber 4. A sprocket 5 is mounted on the outer wall of the rotating shaft 22. A chain 6 is rotatably connected to the outer wall of the sprocket 5. An extension shell 7 is fixedly mounted at the bottom of the support frame 1. A collection bin 8 is slidably connected to the inner wall of the extension shell 7. A rotating rod 9 is rotatably connected to the inner wall of the support frame 1. A magnetic column 10 is mounted on the outer wall of the rotating rod 9. A scraping assembly 11 is installed on the inner wall of the support frame 1. A locking post 12 is slidably connected to the inner wall of the extension shell 7. A pull ring 13 is fixedly installed at the bottom of the locking post 12. A spring 14 is provided on the inner wall of the extension shell 7. A pushing cylinder 15 is fixedly installed on the top of the collecting chamber 4. A cylinder controller 16 is fixedly installed on the outer wall of the pushing cylinder 15. A sealing plate 17 is slidably connected to the inner wall of the collecting chamber 4. A bearing assembly 18 is provided on the inner wall of the collecting chamber 4. A valve 19 is installed on the outer wall of the collecting chamber 4. A weighing device 20 is installed at the bottom of the collecting chamber 4. An extrusion plate assembly 21 is provided on the inner wall of the collecting chamber 4.

[0033] In the above structure, the spring 14 pushes the locking pin 12 upward, so that the locking pin 12 fits into the shape of the inner wall of the collection chamber 8, and thus the position of the collection chamber 8 inside the extension shell 7 is fixed.

[0034] In a preferred embodiment: the scraping assembly 11 includes a mounting plate 1101, a scraper 1102 is provided on the outer wall of the mounting plate 1101, an extension plate 1103 is fixedly installed on the outer wall of the scraper 1102, an insertion plate 1104 is fixedly installed on the outer wall of the extension plate 1103, a rotating screw 1105 is rotatably connected to the inner wall of the mounting plate 1101, a locking plate 1107 is slidably connected to the inner wall of the mounting plate 1101, and a screw nut 1106 is fixedly installed on the outer wall of the locking plate 1107.

[0035] In the above structure, by rotating the lead screw 1105, the lead screw 1105 is connected to the lead screw nut 1106 by a thread, causing the lead screw nut 1106 to move. This causes the lead screw nut 1106 to move the locking plate 1107, allowing the locking plate 1107 to fit into the inner wall of the insertion plate 1104, thereby fixing the insertion plate 1104, the extension plate 1103, and the scraper 1102.

[0036] In a preferred embodiment: the supporting component 18 includes a first upright plate 1801, a filter plate 1802 is fixedly installed on the outer wall of the first upright plate 1801, a second upright plate 1803 is fixedly installed on the top of the filter plate 1802, a rack 1804 is slidably connected to the inner wall of the first upright plate 1801, a fixing plate 1805 is fixedly installed on the inner wall of the first upright plate 1801, a limit rod 1806 is fixedly installed on the outer wall of the fixing plate 1805, a second spring 1807 is provided on the outer wall of the limit rod 1806, a sliding plate 1808 is fixedly installed on the outer wall of the rack 1804, a pin 1809 is fixedly installed on the outer wall of the sliding plate 1808, and a gear 1810 is rotatably connected to the inner wall of the first upright plate 1801.

[0037] In the above structure, the coolant contained in the debris can flow downward through the filter plate 1802, thereby causing the coolant to flow downward to the bottom of the filter plate 1802, so that the coolant and debris are separated.

[0038] In a preferred embodiment: the extrusion plate assembly 21 includes a lower pressure plate 2101, a rotating plate 2102 is rotatably connected to the inner wall of the lower pressure plate 2101, a connecting column 2103 is fixedly installed on the inner wall of the rotating plate 2102, a worm gear 2104 is fixedly installed on the outer wall of the connecting column 2103, a second motor 2105 is fixedly installed on the inner wall of the lower pressure plate 2101, a drive shaft 2106 is fixedly installed on the output shaft of the second motor 2105, and a worm gear 2107 is fixedly installed on the outer wall of the drive shaft 2106.

[0039] In the above structure, by starting the second motor 2105, the second motor 2105 drives the drive shaft 2106 to rotate, which in turn drives the worm wheel 2104 to rotate through meshing with the worm wheel 2104. In turn, the worm wheel 2104 drives the connecting column 2103 and the rotating plate 2102 to rotate, thereby opening the rotating plate 2102.

[0040] In a preferred embodiment, there are two sprockets 5, and the two sprockets 5 are located on the outer walls of the rotating shaft 22 and the rotating rod 9, respectively, and the two sprockets 5 are located on the inner wall of the chain 6.

[0041] In the above structure, the starting of motor 3 causes the rotating shaft 22 to rotate, which in turn causes the chain conveyor belt 2 and the sprocket 5 to rotate simultaneously. This causes the sprocket 5 to drive the chain 6 to rotate, which in turn causes the chain 6 to drive another sprocket 5 to rotate, which in turn causes the rotating rod 9 to rotate, which in turn causes the magnetic column 10 to rotate.

[0042] In a preferred embodiment, there are two push cylinders 15 and cylinder controllers 16, and the two push cylinders 15 and cylinder controllers 16 are symmetrically arranged on the top of the material collection chamber 4, and the two cylinder controllers 16 are electrically connected.

[0043] In the above structure, the electrical connection of the two cylinder controllers 16 enables the two push cylinders 15 to move simultaneously when driven by the two cylinder controllers 16.

[0044] In a preferred embodiment: the scraper 1102 is located outside the magnetic column 10 and is in contact with the outer wall of the magnetic column 10, and the rotating rod 9 is located at the bottom of the chain conveyor belt 2.

[0045] In the above structure, the debris attached to the outside of the chain conveyor belt 2 is adsorbed onto the outer wall of the magnetic column 10. At the same time, the rotation of the magnetic column 10 causes the external debris to rotate. Meanwhile, the scraper 1102 is attached to the outer wall of the magnetic column 10, so that the debris on the outside of the magnetic column 10 is scraped off by the scraper 1102.

[0046] In a preferred embodiment, the shape of the insert 1809 is adapted to the shape of the inner wall of the collection chamber 4, and the position of the insert 1809 corresponds to that of the inner wall of the collection chamber 4.

[0047] In the above structure, the sliding plate 1808 is pushed by the rebound of the second spring 1807, which in turn causes the sliding plate 1808 to move the insertion post 1809, which in turn causes the insertion post 1809 to enter the inner wall of the collection chamber 4, thereby fixing the position of the insertion post 1809. At this time, the insertion post 1809 fixes the entire bearing assembly 18 inside the collection chamber 4.

[0048] In a preferred embodiment, there are two racks 1804, fixed plate 1805, limiting rod 1806, spring 1807, sliding plate 1808 and insert 1809. The two racks 1804, fixed plate 1805, limiting rod 1806, spring 1807, sliding plate 1808 and insert 1809 are arranged diagonally on the inner wall of the upright plate 1801. The two racks 1804 are located on the upper and lower sides of the gear 1810, and the limiting rod 1806 passes through the sliding plate 1808.

[0049] In the above structure, by rotating the gear 1810, the gear 1810 meshes with the two racks 1804, causing the two racks 1804 to move. The two racks 1804 then move the external sliding plate 1808 toward the gear 1810, which in turn causes the two sliding plates 1808 to move the external insert 1809. At the same time, the limiting rod 1806 passes through the sliding plate 1808, limiting the sliding plate 1808 and preventing it from tilting during movement.

[0050] In a preferred embodiment, the lower pressure plate 2101 is located above the bearing assembly 18, and the shape of the lower pressure plate 2101 is adapted to the inner wall of the collection chamber 4.

[0051] In the above structure, by activating the push cylinder 15, the push cylinder 15 drives the lower pressure plate 2101 to move downward, thereby causing the lower pressure plate 2101 to move upward toward the support assembly 18, and at the same time squeezing the debris above the support assembly 18, so that the debris is squeezed into blocks, and the internal coolant is squeezed out.

[0052] Working principle: When the equipment is in use, starting motor 3 causes the rotating shaft 22 to rotate, which in turn causes the chain conveyor belt 2 and sprocket 5 to rotate simultaneously. Sprocket 5 then drives chain 6 to rotate, which in turn drives another sprocket 5 to rotate, causing rotating rod 9 to rotate. Rotating rod 9 then drives magnetic column 10 to rotate. As the chain conveyor belt 2 transports debris, the magnetic column 10 rotates simultaneously. The magnetic column 10 attracts debris adhering to the bottom of the chain conveyor belt 2 to its surface. Simultaneously, the rotation of the magnetic column 10 causes the scraper 1102 to scrape off the debris from its surface, thus moving the debris towards the collection point. When debris falls into the collection bin 8, pulling the pull ring 13 causes the lock pin 12 to move downwards, separating it from the inner wall of the collection bin 8. This allows the collection bin 8 to be pulled outwards, thus concentrating the debris inside. Simultaneously, when the scraper 1102 needs replacement, rotating the screw 1105 causes the screw nut 1106 and the lock plate 1107 to move, separating the lock plate 1107 from the insertion plate 1104. The scraper 1102 can then be replaced. After replacement, the structure can be reset. The debris is transported by the chain conveyor belt 2 into the collection chamber 4, falling onto the filter plate 1802. Weighing device 20 weighs the debris entering the collection chamber 4. When the operator observes that the debris weight reaches the threshold, the sealing plate 17 is closed, sealing the top of the collection chamber 4 and preventing debris from entering. Simultaneously, motor 2105 is started, causing the drive shaft 2106 and worm gear 2107 to rotate. The meshing of worm gear 2107 and worm wheel 2104 causes the worm wheel 2104 to rotate, which in turn causes the rotating plate 2102 and connecting column 2103 to rotate, thus closing the rotating plate 2102. At this time, the push cylinder 15 is activated, causing the lower pressure plate 2101 to move downward, thereby pressing the filter plate down. The debris above filter plate 1802 is compressed, causing it to be crushed into blocks. Simultaneously, the internal coolant is squeezed out and flows downward. At this time, by rotating gear 1810, the gear 1810 meshes with two racks 1804, causing the two racks 1804 to move. The two racks 1804 then move the external sliding plate 1808 towards the gear 1810, which in turn moves the external insert 1809. At this point, the fixed relationship of the bearing assembly 18 disappears, and the bearing assembly 18 is pulled outward, causing the filter plate 1802 to move the debris above it out. Since the debris is crushed into blocks, the debris occupies a small area and is easy to transport.
