Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a double-column vertical lathe with a milling CNC integrated machine. Background Technology

[0002] In the machining of metal rotating workpieces, vertical machine tools are typically used to treat the workpiece surface. To improve production efficiency and meet the diverse surface machining requirements of rotating metal workpieces, integrated milling machines have emerged that combine milling operations onto a single machine tool.

[0003] In related technologies, such as Chinese patent document CN205057508U, a double-column vertical lathe with milling CNC integrated machine is disclosed. It includes a crossbeam with vertical tool holders movably mounted at both ends. One end of one vertical tool holder is fixedly equipped with a cutting head, and the other end of the other vertical tool holder is movably equipped with a CNC milling head. Both the cutting head and the CNC milling head face the workpiece, which is placed on a worktable resting on a rotating mechanism. During machining, the workpiece is fixed on the worktable, and the turning or milling of the metal rotating workpiece is completed through the feed of the two vertical tool holders and the rotation of the worktable.

[0004] Regarding the aforementioned technologies, when the worktable rotates the metal workpiece for processing, the chips are easily splashed out under the action of centrifugal force, posing a safety hazard. Summary of the Invention

[0005] This invention discloses a double-column vertical lathe with a milling CNC integrated machine, which can block and collect chips splashed under centrifugal force to a certain extent, thus helping to reduce safety hazards.

[0006] The present invention provides a dual-column vertical lathe with milling CNC integrated machine, which adopts the following technical solution:

[0007] A double-column vertical lathe with milling CNC integrated machine tool includes a machine tool and a worktable rotatably mounted on the machine tool, and also includes an extension assembly, a flexible protective cover and an adjustment mechanism;

[0008] The extension assembly includes multiple telescopic extension plates slidably disposed on the worktable. The multiple telescopic extension plates are arranged at intervals along the circumference of the worktable, the telescopic extension plates are slidably disposed along the radial direction of the worktable, and the telescopic extension direction of the telescopic extension plates is disposed along the vertical direction.

[0009] The flexible protective cover is ring-shaped, with its inner side set on the workbench and its outer side set on multiple telescopic extension plates.

[0010] The adjustment mechanism is set on the workbench and is used to adjust the multiple telescopic extension plates to move away from the center of the workbench and extend upwards, or to adjust the multiple telescopic extension plates to move closer to the center of the workbench and retract downwards.

[0011] Furthermore, each of the telescopic extension plates includes a first plate and a second plate. The first plate is slidably disposed on the worktable along the radial direction, and the second plate is slidably sleeved on the corresponding first plate along the vertical direction.

[0012] Furthermore, the adjustment mechanism includes a pull spring, a first push spring, a push assembly, and an adsorption assembly;

[0013] The pull spring corresponds one-to-one with the telescopic extension plate. One end of the pull spring is set on the workbench, and the other end is set on the first plate of the corresponding telescopic extension plate. The pull spring is used to pull the corresponding first plate towards the center of the workbench.

[0014] The first push spring corresponds to the telescopic extension plate one by one. One end of the first push spring is set on the corresponding first plate and the other end is set on the corresponding second plate. The first push spring is used to push the corresponding second plate to move away from the worktable.

[0015] The pushing component is disposed inside the worktable, and the pushing component is used to push a plurality of first plates to move away from the center of the worktable when the worktable is rotated;

[0016] The adsorption assembly is mounted on the workbench and is used to adsorb the second plate and move it toward the workbench when the pull spring is in its natural state.

[0017] Furthermore, the pushing assembly includes a support rod, an extension rod slidably passing through the support rod, an abutment strip disposed on the extension rod, and a reset member disposed on the support rod. The worktable has an annular mounting cavity. Multiple support rods are arranged circumferentially along the annular mounting cavity. The extension rod slides radially along the worktable. The first plate is slidably passing through the annular mounting cavity. The abutment strip is located on the side of the first plate near the center of the worktable and is used to abut against the first plate. The reset member is used to pull the extension rod toward the direction closer to the center of the worktable for reset.

[0018] Furthermore, the reset component includes an elastic rope disposed between the support rod and the extension rod, wherein when the elastic rope is in its natural state, the abutment strip is disengaged from the first plate.

[0019] Furthermore, the abutment strips corresponding to adjacent support rods are staggered vertically.

[0020] Furthermore, the adsorption assembly includes a first magnet disposed on the workbench and a second magnet disposed on the second plate. The first magnet corresponds to the second plate one-to-one. The first magnet is used to attract the second magnet and drive the corresponding second plate to move toward the workbench. The adsorption force between the first magnet and the second magnet is greater than the elastic force of the first push spring. When the pull spring is in its natural state, the second magnet is aligned with the corresponding first magnet.

[0021] Furthermore, a fixed plate is provided on the workbench, and the fixed plate corresponds one-to-one with the telescopic extension plate. A sliding plate is slidably provided on the workbench, and the sliding plate corresponds one-to-one with the telescopic extension plate. The sliding direction of the sliding plate is parallel to the sliding direction of the corresponding telescopic extension plate. The telescopic extension plate, the corresponding fixed plate, and the corresponding sliding plate are arranged sequentially along the direction close to the center of the workbench. The inner side of the flexible protective cover is provided on multiple sliding plates. Multiple fixed plates are connected to the flexible protective cover. The upper surface of the sliding plate is higher than the upper surface of the fixed plate. The upper surface of the second plate is higher than the upper surface of the sliding plate. A sliding component for adjusting the sliding of the sliding plate is provided on the fixed plate.

[0022] Furthermore, the sliding assembly includes a second push spring disposed on the fixed plate and an adsorption moving member disposed on the first plate. The second push spring is used to push the corresponding sliding plate to slide away from the fixed plate, and the adsorption moving member is used to adsorb the sliding plate to slide towards the fixed plate.

[0023] Furthermore, the adsorption moving member includes a third magnet disposed on the first plate and a fourth magnet disposed on the sliding plate. The third magnet is used to attract the fourth magnet to drive the sliding plate to slide towards the fixed plate. The adsorption force between the third magnet and the fourth magnet is greater than the elastic force of the second push spring.

[0024] The double-column vertical lathe with milling CNC integrated machine of the present invention has at least the following beneficial effects:

[0025] 1. During processing, the metal workpiece is fixedly placed on the worktable. Then, the rotating mechanism drives the worktable and the metal workpiece on the worktable to rotate. The adjusting mechanism adjusts multiple telescopic extension plates to move away from the center of the worktable and extend upward. This causes the outer side of the flexible protective cover to expand upward and outward. The outer side of the flexible protective cover is moved outside the cutting head and milling head. When the cutting head and / or milling head processes the metal workpiece, the flexible protective cover can block the chips splashed out under centrifugal force to a certain extent, which helps to reduce safety hazards.

[0026] 2. When processing is completed and the worktable stops rotating, multiple telescopic extension plates move towards the center of the worktable and retract downwards. The third magnet attracts the fourth magnet, which drives the sliding plate to slide towards the fixed plate until the third magnet and the fourth magnet are attracted and engaged. At this time, the sliding plate approaches the corresponding fixed plate, and the entire flexible protective cover returns to a V-shaped retracted state to facilitate the collection of chips for subsequent processing and to prevent pollution of the surrounding environment or the worktable.

[0034] The following combination Figures 1-5 The present invention will be described in further detail below.

[0035] This invention discloses a dual-column vertical lathe with integrated milling CNC machine. (Refer to...) Figure 1The double-column vertical lathe with milling integrated CNC machine includes a machine tool 1 and a worktable 2. The machine tool 1 is a vertical CNC lathe, and the machining tools are the same as those in related technologies, both equipped with cutting heads and milling heads to achieve integrated milling. The worktable 2 is rotatably mounted on the machine tool 1 via a motor or other rotating mechanism. The worktable 2 has a circular cross-section and is used to place metal workpieces. The cutting heads and milling heads on the machine tool 1 are located above the worktable 2. Specifically, to prevent the rotating metal workpiece from slipping during machining, a fixing mechanism for fixing the metal workpiece is set at the center of the worktable 2. The fixing mechanism can adopt a three-jaw chuck fixing method, a center fixing method, or a magnetic chuck fixing method.

[0036] Reference Figure 1 and Figure 2 The double-column vertical lathe with milling CNC integrated machine also includes an extension group, a flexible protective cover 3 and an adjustment mechanism; wherein, the extension group includes multiple telescopic extension plates 4, which are arranged at intervals along the circumference of the worktable 2, and each telescopic extension plate 4 is slidably set on the surface of the worktable 2, the telescopic extension plates 4 are slidably set along the radial direction of the worktable 2, and the extension direction of the telescopic extension plates 4 is set along the vertical direction.

[0037] Reference Figure 2 and Figure 3 Specifically, the worktable 2 has more than six telescopic extension plates 4. Each telescopic extension plate 4 includes a first plate 41 and a second plate 42. The first plate 41 is slidably disposed on the worktable 2 along the radial direction. The worktable 2 has a slotted hole 18 that slides with the first plate 41, thereby guiding the sliding of the first plate 41 and preventing it from moving in other directions. The sliding engagement between the first plate 41 and the corresponding slotted hole 18 can be a slider and groove engagement or a slider and rail engagement, which is not limited here. The second plate 42 is slidably fitted onto the corresponding first plate 41 along the vertical direction. Through the mutual engagement of the first plate 41 and the second plate 42, the telescopic extension plate 4 can be extended outward and upward or retracted inward and downward.

[0038] Reference Figure 2 and Figure 3 The flexible protective cover 3 is annular and concentrically positioned with the worktable 2. During processing, the metal workpiece is located within the annular flexible protective cover 3. The inner side of the flexible protective cover 3 is positioned on the worktable 2, and the outer side of the flexible protective cover 3 is positioned on the upper end of the second plate 42 of the multiple telescopic extension plates 4. Furthermore, the flexible protective cover 3 is made of elastic flexible fabric; when the telescopic extension plates 4 are in their initial contracted state, the flexible protective cover 3 is in its retracted state.

[0039] Reference Figure 2The adjustment mechanism is set on the workbench 2. The adjustment mechanism is used to adjust the multiple telescopic extension plates 4 to move away from the center of the workbench 2 and extend upward, or to adjust the multiple telescopic extension plates 4 to move closer to the center of the workbench 2 and retract downward.

[0040] During processing, the metal workpiece is placed on the worktable 2 and fixed. Then, the rotating mechanism drives the worktable 2 and the metal workpiece on the worktable 2 to rotate. The adjusting mechanism adjusts multiple first plates 41 to move away from the center of the worktable 2 and causes the second plates 42 to extend upward. This causes the outer side of the flexible protective cover 3 to expand upward and outward, moving the outer side of the flexible protective cover 3 outside the cutting head and milling head. Thus, when the cutting head and / or milling head processes the surface of the metal workpiece, the flexible protective cover 3 can block the chips splashed out under the action of centrifugal force to a certain extent, which helps to reduce safety hazards.

[0041] Reference Figure 2 and Figure 3 To facilitate the adjustment of multiple telescopic extension plates 4 to move away from the center of the workbench 2 and extend upwards, or to move closer to the center of the workbench 2 and retract downwards, a fixing plate 13 is fixed on the workbench 2. The fixing plate 13 corresponds one-to-one with the telescopic extension plates 4. The fixing plate 13 is located on the side of the first plate 41 of the corresponding telescopic extension plate 4 closer to the center of the workbench 2. The tops of the multiple fixing plates 13 are fixedly connected to the bottom wall of the flexible protective cover 3. The upper surface of the fixing plate 13 is lower than the upper surface of the second plate 42. The adjustment mechanism includes a pull spring 5, a first push spring 6, a push assembly, and an adsorption assembly 1. 2; The pull spring 5 corresponds one-to-one with the telescopic extension plate 4. The extension direction of the pull spring 5 is parallel to the sliding direction of the corresponding first plate 41. The pull spring 5 is located between the corresponding fixed plate 13 and the first plate 41. One end of the pull spring 5 is fixed on the fixed plate 13, and the other end is fixed on the first plate 41 of the corresponding telescopic extension plate 4. The pull spring 5 is close to the surface of the workbench 2. The pull spring 5 is used to pull the corresponding first plate 41 to move towards the center of the workbench 2. When the pull spring 5 is in its natural state, the flexible protective cover 3 is in its retracted state. When the pull spring 5 is in its natural state, the telescopic extension plate 4 is in its initial state.

[0042] Reference Figure 2 and Figure 3 The first push spring 6 corresponds one-to-one with the telescopic extension plate 4. The first push spring 6 is located inside the second plate 42 of the corresponding telescopic extension plate 4. One end of the first push spring 6 is fixed to the upper end of the corresponding first plate 41, and the other end is fixed to the inner wall of the corresponding second plate 42. The first push spring 6 is used to push the corresponding second plate 42 to move away from the worktable 2. When the pull spring 5 is in the natural state, the first push spring 6 is in the compressed state.

[0043] Reference Figure 2 and Figure 3 The pushing component is installed inside the worktable 2. The pushing component is used to push multiple first plates 41 to move away from the center of the worktable 2 when the worktable 2 is rotated. The adsorption component 12 is installed on the worktable 2. The adsorption component 12 is used to adsorb the second plate 42 to move closer to the worktable 2 when the pull spring 5 is in the natural state.

[0044] When the rotating mechanism drives the worktable 2 and the metal workpiece on the worktable 2 to rotate, the pushing component pushes multiple first plates 41 to move away from the center of the worktable 2, stretching the pull spring 5. Then, under the action of the first pushing spring 6, the second plate 42 moves away from the worktable 2, thereby causing the telescopic extension plate 4 to move away from the center of the worktable 2 and extend upward. This helps to unfold the flexible protective cover 3 and move it outside the cutting head and milling head. Thus, when the cutting head and / or milling head processes the metal workpiece, the flexible protective cover 3 can block the chips that are splashed out under the action of centrifugal force to a certain extent, which helps to reduce safety hazards.

[0045] Reference Figure 2 and Figure 3 To facilitate the movement of multiple first plates 41 away from the center of the worktable 2 during rotation, an annular mounting cavity 10 is provided inside the worktable 2. The annular mounting cavity 10 is concentrically arranged with the worktable 2, and the strip hole 18 communicates with the annular mounting cavity 10. The lower end of the first plate 41 extends into the annular mounting cavity 10. The pushing assembly includes a support rod 7, an extension rod 8, an abutment strip 9, and a reset member. Multiple support rods 7 are distributed circumferentially along the annular mounting cavity 10. The support rods 7 are fixed to the inner wall of the annular mounting cavity 10 and extend radially along the worktable 2. The extension rod 8 corresponds to the support rod 7 one by one. The extension rod 8 slides through the corresponding support rod 7 and slides radially along the worktable 2. The end of the extension rod 8 away from the support rod 7 is integrally formed with a counterweight ball 19. The abutment strip 9 corresponds to the extension rod 8 one by one. The abutment strip 9 is fixed on the counterweight ball 19 on the side of the corresponding extension rod 8 away from the support rod 7. The abutment strip 9 is arc-shaped and is located on the side of the first plate 41 near the center of the worktable 2. The abutment strip 9 is used to abut against the first plate 41. Specifically, there is an overlapping part between adjacent abutment strips 9.

[0046] Reference Figure 2 and Figure 3The reset component is installed inside the support rod 7. The reset component is used to pull the extension rod 8 towards the center of the worktable 2 for reset. To facilitate the movement of the extension rod 8 towards the center of the worktable 2 for reset, the reset component includes an elastic rope 11. The elastic rope 11 corresponds to the support rod 7 one by one. The elastic rope 11 is located inside the corresponding support rod 7. One end of the elastic rope 11 is fixed to the inner wall of the support rod 7 away from the extension rod 8, and the other end is fixed to the side of the extension rod 8 inside the support rod 7. When the elastic rope 11 is in its natural state, the abutment strip 9 is disengaged from the first plate 41. The sum of the elastic force of the elastic rope 11 and the elastic force of the pulling spring 5 is less than the centrifugal force of the counterweight ball 19 when the worktable 2 rotates.

[0047] When the workbench 2 is stationary relative to the machine tool 1, the elastic rope 11 is in its natural state. Under the action of the elastic rope 11, the extension rod 8 causes the abutment bar 9 to separate from the first plate 41, so that the first plate 41 is in its initial state under the action of the tension spring 5, so that the telescopic extension plate 4 can retract the flexible protective cover 3 and not easily affect the placement of the metal workpiece.

[0048] When the workbench 2 rotates, the counterweight ball 19, under the action of centrifugal force, will drive the extension rod 8 and the abutment bar 9 to move away from the support rod 7, causing the elastic rope 11 to stretch. Then the abutment bar 9 will push the first plate 41 to move away from the metal workpiece. Since multiple abutment bars 9 are always in contact with the first plate 41 during the rotation of the workbench 2, the first plate 41 can be kept away from the fixed plate 13, which makes it convenient to unfold the flexible protective cover 3.

[0049] Reference Figure 2 and Figure 5 The abutment strips 9 corresponding to adjacent support rods 7 are staggered vertically, so that when multiple extension rods 8 move toward the support rod 7 for retraction, the overlapping parts of adjacent abutment strips 9 will not interfere.

[0050] Reference Figure 2 and Figure 3 To facilitate the movement of the second plate 42 toward the worktable 2 when the pull spring 5 is in its natural state, the adsorption assembly 12 includes a first magnet 121 and a second magnet 122. The first magnet 121 is fixedly disposed on the surface of the worktable 2, and the first magnet 121 corresponds one-to-one with the second plate 42. The first magnet 121 is located below the corresponding second plate 42, and the second magnet 122 is fixed on the side of the second plate 42 near the worktable 2. The first magnet 121 is used to adsorb the corresponding second magnet 122, thereby moving the second plate 42 toward the worktable 2. The adsorption force between the first magnet 121 and the second magnet 122 is greater than the elastic force of the first push spring 6. When the pull spring 5 is in its natural state, the second magnet 122 is aligned with the first magnet 121.

[0051] When the pull spring 5 is in its natural state, the first plate 41 drives the corresponding second plate 42 to move to align with the first magnet 121. Then, the first magnet 121 attracts the corresponding second magnet 122, causing the second plate 42 to move towards the workbench 2, compressing the first push spring 6, thereby achieving the retracted state of the telescopic extension plate 4. When the first plate 41 drives the second plate 42 to slide away from the fixed plate 13, causing the pull spring 5 to stretch, the first plate 41 drives the second plate 42 to gradually misalign with the corresponding first magnet 121 until the second magnet 122 disengages from the first magnet 121. At this time, the compressed first push spring 6 pushes the second plate 42 to move away from the workbench 2, thereby achieving the extension of the telescopic extension plate 4.

[0052] Reference Figure 3 and Figure 4 A sliding plate 14 is slidably arranged on the workbench 2. The sliding plate 14 corresponds one-to-one with the telescopic extension plate 4. The sliding direction of the sliding plate 14 is parallel to the sliding direction of the corresponding telescopic extension plate 4. The telescopic extension plate 4, the corresponding fixed plate 13 and the corresponding sliding plate 14 are arranged in sequence along the direction close to the center of the workbench 2. The inner side of the flexible protective cover 3 is fixedly arranged on the upper end of multiple sliding plates 14. The upper surface of the sliding plate 14 is higher than the upper surface of the fixed plate 13. When the pulling spring 5 is in the natural state, the upper surface of the sliding plate 14 is lower than the upper surface of the second plate 42. The fixed plate 13 is provided with a sliding component for adjusting the sliding of the sliding plate 14.

[0053] Reference Figure 3 and Figure 4 To facilitate the adjustment of the sliding plate 14, the sliding assembly includes a second push spring 15 and an adsorption moving member. The second push spring 15 corresponds to the sliding plate 14 one by one. One end of the second push spring 15 is fixed on the corresponding fixed plate 13, and the other end is fixed on the corresponding sliding plate 14. The extension direction of the second push spring 15 is parallel to the sliding direction of the sliding plate 14. The second push spring 15 is used to push the corresponding sliding plate 14 to slide away from the fixed plate 13. The adsorption moving member is disposed on the first plate 41 and is used to adsorb the sliding plate 14 to slide towards the fixed plate 13.

[0054] Reference Figure 3 and Figure 4To facilitate the sliding of the sliding plate 14 towards the fixed plate 13, the adsorption moving component includes a third magnet 16 and a fourth magnet 17. The third magnet 16 is disposed on the first plate 41 and located below the second plate 42, so as not to interfere with the movement of the second plate 42. The fixed plate 13 has an opening 21 for the third magnet 16 to pass through, and the cross-sectional area of ​​the opening 21 is larger than the cross-sectional area of ​​the third magnet 16. The fourth magnet 17 is embedded in the sliding plate 14. The third magnet 16 is used to attract the fourth magnet 17 and drive the sliding plate 14 towards the fixed plate 13. The adsorption force between the third magnet 16 and the fourth magnet 17 is greater than the elastic force of the second push spring 15. When the pull spring 5 is in the natural state, the third magnet 16 and the fourth magnet 17 are in an adsorbed and fixed state.

[0055] When the pulling spring 5 is in its natural state, the third magnet 16 and the fourth magnet 17 are attracted and fixed, causing the second pushing spring 15 to be compressed, and the sliding plate 14 to approach the corresponding fixed plate 13. At this time, the entire flexible protective cover 3 is in a V-shaped folded state.

[0056] When the first plate 41 moves away from the fixed plate 13, the third magnet 16 disengages from the corresponding fourth magnet 17. Then, under the action of the second push spring 15, the sliding plate 14 slides towards the metal workpiece, causing it to come into contact with the workpiece. This unfolds the flexible protective cover 3, facilitating chip collection and preventing chip accumulation on the worktable 2. After processing is complete and the worktable 2 stops rotating, the first plate 41 slides towards the fixed plate 13, allowing the third magnet 16 to pass through the opening 21 on the corresponding fixed plate 13. The third magnet 16 then attracts the corresponding fourth magnet 17, causing the sliding plate 14 to slide towards the fixed plate 13 until the third magnet 16 and the fourth magnet 17 are attracted and engaged, bringing the sliding plate 14 close to the corresponding fixed plate 13. At this point, the entire flexible protective cover 3 returns to its V-shaped retracted state, facilitating chip collection for subsequent processing and preventing contamination of the surrounding environment or the worktable 2.

[0057] Reference Figure 3 and Figure 4To facilitate the adaptation of conical rotating metal workpieces, the sliding plate 14 includes a sliding seat 141 and a bonding plate 142. The sliding seat 141 is slidably connected to the surface of the worktable 2, and the sliding direction of the sliding seat 141 is parallel to the sliding direction of the corresponding first plate 41. The end of the second push spring 15 away from the fixed plate 13 is fixed to the sliding seat 141 of the corresponding sliding plate 14. The bonding plate 142 is hinged to the sliding seat 141, and the hinge axis of the bonding plate 142 is perpendicular to the sliding direction of the sliding seat 141. A torsion spring 20 is sleeved on the hinge axis of the bonding plate 142. One end of the torsion spring 20 is fixed to the sliding seat 141, and the other end is fixed to the bonding plate 142. The torsion spring 20 is used to drive the bonding plate 142 to rotate in a direction away from the fixed plate 13. The fourth magnet 17 is embedded in the sliding plate 142. On the side of the bonding plate 142 near the fixing plate 13, the cross-sectional area of ​​the fourth magnet 17 is larger than that of the third magnet 16; the attraction force between the third magnet 16 and the fourth magnet 17 is greater than the sum of the torque of the torsion spring 20 and the thrust of the second push spring 15. When the torsion spring 20 is in its natural state, the angle between the side of the bonding plate 142 away from the fixing plate 13 and the surface of the worktable 2 is greater than 60 degrees; the torque of the torsion spring 20 is less than the thrust of the second push spring 15; the sliding seat 141 is fixed with a limiting plate 22 on the side near the fixing plate 13. When the bonding plate 142 abuts against the limiting plate 22, the bonding plate 142 is in a vertical state; when the pulling spring 5 is in its natural state, the third magnet 16 and the fourth magnet 17 are attracted and engaged, and the bonding plate 142 is in a vertical state.

[0058] When the first plate 41 moves away from the fixed plate 13, the third magnet 16 disengages from the corresponding fourth magnet 17. Then, the sliding seat 141 slides towards the metal workpiece under the action of the second push spring 15. Then, the bonding plate 142 rotates away from the fixed plate 13 under the action of the torsion spring 20, so that the upper end of the bonding plate 142 abuts against the metal workpiece, thereby causing the flexible protective cover 3 to unfold, which helps to ensure the chip collection effect of the conical metal workpiece.

[0059] The implementation principle of this invention is as follows: During processing, the metal workpiece is placed on the workbench 2 and fixed. At this time, the sliding plate 14, the telescopic extension plate 4 and the extension rod 8 are all in the initial state, that is, the pulling spring 5 is in the natural state, the first magnet 121 and the second magnet 122 are in the adsorption and fixing state, the third magnet 16 and the fourth magnet 17 are in the adsorption and fixing state, and the flexible protective cover 3 is in the retracted state.

[0060] Next, the rotating mechanism drives the worktable 2 and the metal workpiece on it to rotate. The counterweight ball 19, under centrifugal force, drives the extension rod 8 and the abutment bar 9 to move away from the support rod 7. Then, multiple abutment bars 9 push multiple first plates 41 to move away from the metal workpiece. Next, the first magnet 121 disengages from its corresponding second magnet 122, and the third magnet 16 disengages from its corresponding fourth magnet 17. Then, the compressed first push spring 6 pushes the second plate 42 to move away from the worktable 2. Multiple second plates 42 cause the flexible protective cover 3 to unfold upwards and outwards, thus... The outer side of the flexible protective cover 3 moves to the outside of the cutting head and milling head, while the sliding seat 141 slides towards the metal workpiece under the action of the second push spring 15. Then, the bonding plate 142 rotates away from the fixed plate 13 under the action of the torsion spring 20, so that the upper end of the bonding plate 142 abuts against the metal workpiece, thereby causing the flexible protective cover 3 to unfold inward, so that the entire flexible protective cover 3 is in a V-shaped unfolded state. Thus, when the cutting head and / or milling head processes the metal workpiece, the flexible protective cover 3 can block the chips splashed out under the action of centrifugal force to a certain extent and collect them, which helps to reduce safety hazards.

[0061] After the metal workpiece is processed and the worktable 2 stops rotating, the counterweight ball 19 is no longer subjected to centrifugal force. Then, under the pull of the elastic rope 11, the extension rod 8 moves towards the support rod 7, reducing the abutment force of the abutment strip 9 on the first plate 41 until the abutment strip 9 at the end of the extension rod 8 disengages from the first plate 41. At this time, the first plate 41 moves towards the fixed plate 13 under the action of the pulling spring 5. Then, the first plate 41 returns to its initial state, the second magnet 122 aligns with the first magnet 121, and the first magnet 121 attracts the corresponding second magnet 122, causing the second plate 42 to move towards the worktable 2, pressing... The first push spring 6 is compressed, thereby realizing the retracted state of the telescopic extension plate 4; the third magnet 16 passes through the corresponding opening 21 and first attracts the fourth magnet 17, causing the bonding plate 142 to rotate towards the direction of the fixed plate 13 to a vertical state and abut against the limiting plate 22. Then, it continues to attract the fourth magnet 17, causing the sliding seat 141 to slide towards the direction of the fixed plate 13 until the third magnet 16 and the fourth magnet 17 are completely attracted and engaged. At this time, the sliding seat 141 approaches the corresponding fixed plate 13, and the entire flexible protective cover 3 returns to the V-shaped retracted state, which helps to collect chips, facilitates subsequent processing, and is less likely to pollute the surrounding environment or the workbench 2.

[0062] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
