Technical Field

[0001] The present invention relates to the technical field of metal processing, and particularly relates to a double-column vertical lathe with a milling integrated numerically controlled machine. Background Art

[0002] In the processing of metal revolving body workpieces, a vertical machine tool is usually required to process the surface of the workpiece. To improve production efficiency and meet the various surface processing requirements of revolving body metal workpieces, an integrated machine that integrates milling on the same machine has emerged currently.

[0003] In the related art, for example, a Chinese patent document with the publication number CN205057508U discloses a double-column vertical lathe with a milling integrated numerically controlled machine, which includes a crossbeam. Vertical tool carriers are movably installed at both ends of the crossbeam. A tool head is fixedly installed at one end of one of the vertical tool carriers, and a numerically controlled milling head is movably installed at one end of the other vertical tool carrier. The tool head and the numerically controlled milling head both face the workpiece. The workpiece is placed on a workbench, and the workbench is placed on a rotating mechanism. During processing, the workpiece is fixed on the workbench, and turning or milling of the metal revolving body workpiece is completed through the feeding of the two vertical tool carriers and the rotation of the workbench.

[0004] Aiming at the above related art, when the workbench drives the metal workpiece to rotate for processing, chips are likely to fly out under the action of centrifugal force, posing a safety hazard. Summary of the Invention

[0005] The present invention discloses a double-column vertical lathe with a milling integrated numerically controlled machine to block and collect chips flying under centrifugal force to a certain extent, which helps to reduce safety hazards.

The plurality of telescopic extension plates are arranged at intervals along the circumferential direction of the workbench. The telescopic extension plates are slidably arranged along the radial direction of the workbench, and the telescopic direction of the telescopic extension plates is arranged in the vertical direction; The flexible protective cover is annular. The inner side of the flexible protective cover is arranged on the workbench, and the outer side of the flexible protective cover is arranged on the plurality of telescopic extension plates; The adjustment mechanism is arranged on the workbench.

[0007] Further, each of the telescopic and extensible plates includes a first plate body and a second plate body. The first plate body is slidably disposed on the workbench along the radial direction of the workbench, and the second plate body is slidably sleeved on the corresponding first plate body along the vertical direction.

[0008] Further, the adjusting mechanism includes a pulling spring, a first pushing spring, a pushing component, and an adsorption component; The pulling springs correspond to the telescopic and extensible plates one by one. One end of each pulling spring is disposed on the workbench, and the other end is disposed on the first plate body of the corresponding telescopic and extensible plate. The pulling springs are used to pull the corresponding first plate bodies to move towards the center of the workbench. The first pushing springs correspond to the telescopic and extensible plates one by one. One end of each first pushing spring is disposed on the corresponding first plate body, and the other end is disposed on the corresponding second plate body. The first pushing springs are used to push the corresponding second plate bodies to move away from the workbench. The pushing component is disposed in the workbench and is used to push a plurality of first plate bodies to move away from the center of the workbench when the workbench rotates; The adsorption component is disposed on the workbench and is used to adsorb the second plate body to move towards the workbench when the pulling spring is in a natural state.

[0009] Further, the pushing component includes a support rod, an extension rod slidably disposed in the support rod, a contact bar disposed on the extension rod, and a reset member disposed on the support rod. An annular installation cavity is formed in the workbench. A plurality of support rods are disposed along the circumferential direction of the annular installation cavity. The extension rod slides along the radial direction of the workbench. The first plate body slidably penetrates into the annular installation cavity. The contact bar is located on the side of the first plate body close to the center of the workbench. The contact bar is used to contact the first plate body, and the reset member is used to pull the extension rod to move towards the center of the workbench for resetting.

[0010] Further, the reset member includes an elastic rope disposed between the support rod and the extension rod. When the elastic rope is in a natural state, the contact bar is separated from the first plate body.

[0011] Further, the contact bars corresponding to adjacent support rods are arranged in a vertically staggered manner.

[0012] Further, the adsorption component includes a first magnet disposed on the workbench and a second magnet disposed on the second plate body. The first magnets correspond to the second plate bodies one by one. The first magnets are used to adsorb the second magnets to drive the corresponding second plate bodies to move towards the workbench. The adsorption force between the first magnet and the second magnet is greater than the elastic force of the first pushing spring. When the pulling spring is in a natural state, the second magnet is aligned with the corresponding first magnet.

[0013] Furthermore, a fixed plate is arranged on the workbench. The fixed plates correspond to the telescopic expansion plates one by one. A sliding plate is slidably arranged on the workbench. The sliding plates correspond to the telescopic expansion plates one by one. The sliding direction of the sliding plate is parallel to the sliding direction of the corresponding telescopic expansion plate. The telescopic expansion plate, the corresponding fixed plate and the corresponding sliding plate are arranged in sequence along the direction close to the center of the workbench. The inner side of the flexible protective cover is arranged on a plurality of sliding plates. A plurality of the 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 body is higher than the upper surface of the sliding plate. A sliding component for adjusting the sliding of the sliding plate is arranged on the fixed plate.

[0014] Furthermore, the sliding component includes a second pushing spring arranged on the fixed plate and an adsorption moving part arranged on the first plate body. The second pushing spring is used to push the corresponding sliding plate to slide away from the fixed plate. The adsorption moving part is used to adsorb the sliding plate to slide towards the fixed plate.

[0015] Furthermore, the adsorption moving part includes a third magnet arranged on the first plate body and a fourth magnet arranged on the sliding plate. The third magnet is used to adsorb 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 pushing spring.

[0016] Adopting the double-column vertical lathe with milling numerical control integrated machine of the present invention has at least the following beneficial effects: 1. During processing, the metal workpiece is fixedly placed on the workbench. Then, the rotating mechanism is driven to drive the workbench and the metal workpiece on the workbench to rotate. The plurality of telescopic expansion plates are adjusted to move away from the center of the workbench and extend upward through the adjusting mechanism, so that the outer sides of the plurality of telescopic expansion plates drive the outer side of the flexible protective cover to expand upward and outward, and the outer side of the flexible protective cover is moved outside the turning head and the milling head. Furthermore, when the turning head and / or the milling head processes the metal workpiece, the flexible protective cover can block the chips splashed under the centrifugal force to a certain extent, which helps to reduce potential safety hazards. 2. After the processing is completed and the workbench stops rotating, the plurality of telescopic expansion plates move towards the center of the workbench and contract downward. The third magnet adsorbs the fourth magnet to drive the sliding plate to slide towards the fixed plate until the third magnet and the fourth magnet are adsorbed and matched. At this time, the sliding plate is close to the corresponding fixed plate, and the entire flexible protective cover returns to the V-shaped closed state, so as to facilitate the collection of chips, which is convenient for subsequent processing and is not easy to pollute the surrounding environment or the workbench.

Detailed implementation manners

[0024] The following will Figures 1-5 further describe the present invention in detail.

[0025] The embodiments of the present invention disclose a double-column vertical lathe with a milling numerical control integrated machine. Refer to Figure 1, The double-column vertical lathe with milling numerical control integrated machine includes a machine tool 1 and a workbench 2. The machine tool 1 is a vertical numerical control lathe, and the processing tools are the same as those in the related technology, both equipped with a turning head and a milling head to achieve integrated milling. The workbench 2 is rotationally arranged on the machine tool 1 through a rotating mechanism such as a motor and a motor. The cross-section of the workbench 2 is circular, and the workbench 2 is used to place metal workpieces. The turning head and the milling head on the machine tool 1 are located above the workbench 2. Specifically, in order to prevent the rotary metal workpiece from sliding during processing, a fixing mechanism for fixing the metal workpiece is provided at the center of the workbench 2. The fixing mechanism can adopt a three-jaw chuck fixing method, a center fixing method, or a magnetic chuck fixing method.

[0026] Refer to Figure 1 and Figure 2 , The double-column vertical lathe with milling numerical control integrated machine further includes an extension group, a flexible protective cover 3, and an adjustment mechanism. Among them, the extension group includes a plurality of telescopic extension plates 4. The plurality of telescopic extension plates 4 are arranged at intervals along the circumference of the workbench 2, and each telescopic extension plate 4 is slidably arranged on the surface of the workbench 2. The telescopic extension plate 4 is slidably arranged along the radial direction of the workbench 2, and the telescopic direction of the telescopic extension plate 4 is arranged along the vertical direction.

[0027] Refer to Figure 2 and Figure 3 , Specifically, the number of telescopic extension plates 4 on the workbench 2 is more than 6. Each telescopic extension plate 4 includes a first plate body 41 and a second plate body 42. The first plate body 41 is slidably arranged on the workbench 2 along the radial direction of the workbench 2. A strip-shaped hole 18 that slidably cooperates with the first plate body 41 is provided on the workbench 2, so as to guide the sliding of the first plate body 41 and prevent the first plate body 41 from moving in other directions. The sliding cooperation method between the first plate body 41 and the corresponding strip-shaped hole 18 can adopt the cooperation of a slider and a chute or the cooperation of a slider and a slide rail, which is not limited here. The second plate body 42 is slidably sleeved on the corresponding first plate body 41 along the vertical direction. Through the mutual cooperation of the first plate body 41 and the second plate body 42, the telescopic extension plate 4 can be extended outward and upward or contracted inward and downward.

[0028] Refer to Figure 2 and Figure 3 , The flexible protective cover 3 is annular, and the flexible protective cover 3 is concentrically arranged with the workbench 2. During processing, the metal workpiece is located inside the annular flexible protective cover 3. The inner side of the flexible protective cover 3 is arranged on the workbench 2, and the outer side of the flexible protective cover 3 is arranged at the upper ends of the second plate bodies 42 of the plurality of telescopic extension plates 4. Further, the flexible protective cover 3 is made of elastic flexible cloth. When the telescopic extension plate 4 is in the initial contracted state, the flexible protective cover 3 is in the retracted state.

[0029] Refer to Figure 2, The adjusting mechanism is arranged on the workbench 2 and is used to adjust the multiple telescopic and extensible plates 4 to move away from the center of the workbench 2 and extend upward, or to adjust the multiple telescopic and extensible plates 4 to move towards the center of the workbench 2 and contract downward.

[0030] During processing, place the metal workpiece on the workbench 2 and fix it; then drive the rotating mechanism to drive the workbench 2 and the metal workpiece on the workbench 2 to rotate. By adjusting the mechanism, adjust the multiple first plate bodies 41 to move away from the center of the workbench 2 and make the second plate bodies 42 extend upward, so that the multiple second plate bodies 42 drive the outer side of the flexible protective cover 3 to expand upward and outward, and move the outer side of the flexible protective cover 3 outside the turning tool head and the milling head. Thus, when the turning tool head and / or the milling head process the surface of the metal workpiece, the flexible protective cover 3 can block the chips splashed under the action of centrifugal force to a certain extent, which helps to reduce potential safety hazards.

[0031] Refer to Figure 2 and Figure 3 , To facilitate adjusting the multiple telescopic and extensible plates 4 to move away from the center of the workbench 2 and extend upward, or to adjust the multiple telescopic and extensible plates 4 to move towards the center of the workbench 2 and contract downward, a fixing plate 13 is fixed on the workbench 2. The fixing plates 13 correspond to the telescopic and extensible plates 4 one by one. The fixing plate 13 is located on the side of the first plate body 41 of the corresponding telescopic and extensible plate 4 close 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 body 42; the adjusting mechanism includes a pulling spring 5, a first pushing spring 6, a pushing component and an adsorption component 12; the pulling springs 5 correspond to the telescopic and extensible plates 4 one by one. The extending direction of the pulling spring 5 is parallel to the sliding direction of the corresponding first plate body 41. The pulling spring 5 is located between the corresponding fixing plate 13 and the first plate body 41. One end of the pulling spring 5 is fixed on the fixing plate 13, and the other end is fixed on the first plate body 41 of the corresponding telescopic and extensible plate 4, on the surface of the pulling spring 5 close to the workbench 2; the pulling spring 5 is used to pull the corresponding first plate body 41 to move towards the center of the workbench 2; when the pulling spring 5 is in the natural state, the flexible protective cover 3 is in the retracted state; when the pulling spring 5 is in the natural state, the telescopic and extensible plate 4 is in the initial state.

[0032] Refer to Figure 2 and Figure 3 , The first pushing springs 6 correspond to the telescopic and extensible plates 4 one by one. The first pushing spring 6 is located inside the second plate body 42 of the corresponding telescopic and extensible plate 4. One end of the first pushing spring 6 is fixed on the upper end of the corresponding first plate body 41, and the other end is fixed on the inner wall of the corresponding second plate body 42. The first pushing spring 6 is used to push the corresponding second plate body 42 to move away from the workbench 2. When the pulling spring 5 is in the natural state, the first pushing spring 6 is in the compressed state.

[0033] Refer to Figure 2 and Figure 3 The pushing component is arranged in the workbench 2 and is used to push a plurality of first plate bodies 41 to move away from the center of the workbench 2 when the workbench 2 rotates; the adsorption component 12 is arranged on the workbench 2 and is used to adsorb the second plate body 42 to move towards the workbench 2 when the pulling spring 5 is in a natural state.

[0034] When the rotating mechanism drives the workbench 2 and the metal workpiece on the workbench 2 to rotate, a plurality of first plate bodies 41 are pushed by the pushing component to move away from the center of the workbench 2, stretching the pulling spring 5, and then under the action of the first pushing spring 6, the second plate body 42 moves away from the workbench 2, so that the telescopic extension plate 4 moves away from the center of the workbench 2 and extends upward, which helps to unfold the flexible protective cover 3 and move it outside the cutter head and the milling head. Thus, when the cutter head and / or the milling head processes the metal workpiece, the flexible protective cover 3 can block the chips splashed under the action of centrifugal force to a certain extent, which helps to reduce potential safety hazards.

[0035] Refer to Figure 2 and Figure 3 To facilitate pushing a plurality of first plate bodies 41 to move away from the center of the workbench 2 when the workbench 2 rotates, an annular installation cavity 10 is formed in the workbench 2. The annular installation cavity 10 is concentric with the workbench 2. The strip-shaped hole 18 is communicated with the annular installation cavity 10. The lower end of the first plate body 41 extends into the annular installation cavity 10. The pushing component includes a support rod 7, an extension rod 8, a contact strip 9 and a reset member. A plurality of support rods 7 are distributed along the circumferential direction of the annular installation cavity 10. The support rods 7 are fixed on the inner side wall of the annular installation cavity 10 and extend along the radial direction of the workbench 2. The extension rods 8 correspond to the support rods 7 one by one. The extension rods 8 are slidably inserted into the corresponding support rods 7. The extension rods 8 slide along the radial direction of the workbench 2. A counterweight ball 19 is integrally formed at one end of the extension rod 8 away from the support rod 7. The contact strips 9 correspond to the extension rods 8 one by one. The contact strips 9 are fixed on the counterweight balls 19 on the side of the corresponding extension rods 8 away from the support rods 7. Among them, the contact strip 9 is arc-shaped. The contact strip 9 is located on the side of the first plate body 41 close to the center of the workbench 2. The contact strip 9 is used to contact the first plate body 41. Specifically, there is an overlapping part between adjacent contact strips 9.

[0036] Refer to Figure 2 and Figure 3, the reset member is arranged inside the support rod 7, and the reset member is used to pull the extension rod 8 to move towards the center of the workbench 2 for reset; to facilitate pulling the extension rod 8 to move towards the center of the workbench 2 for reset, the reset member includes an elastic cord 11, the elastic cords 11 correspond to the support rods 7 one by one, the elastic cords 11 are located inside the corresponding support rods 7, one end of the elastic cord 11 is fixed on the inner wall of the support rod 7 away from the extension rod 8, and the other end is fixed on one side of the extension rod 8 located inside the support rod 7. When the elastic cord 11 is in a natural state, the abutting strip 9 is separated from the first plate body 41; the sum of the elastic force of the elastic cord 11 and the elastic force of the pulling spring 5 is less than the centrifugal force of the counterweight ball 19 when the workbench 2 rotates.

[0037] When the workbench 2 is in a static state relative to the machine tool 1, the elastic cord 11 is in a natural state. Under the action of the elastic cord 11, the extension rod 8 separates the abutting strip 9 from the first plate body 41, so that the first plate body 41 is in an initial state under the action of the pulling spring 5, facilitating the telescopic expansion plate 4 to retract the flexible protective cover 3 and not easily affecting the placement of metal workpieces.

[0038] When the workbench 2 rotates, under the action of centrifugal force, the counterweight ball 19 will drive the extension rod 8 and the abutting strip 9 to move away from the support rod 7, stretching the elastic cord 11. Then the abutting strip 9 will push the first plate body 41 to move away from the metal workpiece. Since during the rotation of the workbench 2, multiple abutting strips 9 are always in contact with the first plate body 41, it can be ensured that the first plate body 41 is in a state away from the fixed plate 13, facilitating the unfolding of the flexible protective cover 3.

[0039] Refer to Figure 2 and Figure 5 , the corresponding abutting strips 9 of adjacent support rods 7 are arranged vertically offset, so that when multiple extension rods 8 move towards the support rod 7 for recycling, the overlapping parts of adjacent abutting strips 9 will not interfere.

[0040] Refer to Figure 2 and Figure 3 , to facilitate the movement of the second plate body 42 towards the workbench 2 when the pulling spring 5 is in a natural state, the adsorption assembly 12 includes a first magnet 121 and a second magnet 122. The first magnet 121 is fixedly arranged on the surface of the workbench 2, the first magnets 121 correspond to the second plate bodies 42 one by one, the first magnets 121 are located below the corresponding second plate bodies 42, the second magnet 122 is fixed on the side edge of the second plate body 42 close to the workbench 2. The first magnet 121 is used to adsorb the corresponding second magnet 122 to drive the second plate body 42 to move towards the workbench 2. The adsorption force between the first magnet 121 and the second magnet 122 is greater than the elastic force of the first pushing spring 6. When the pulling spring 5 is in a natural state, the second magnet 122 is aligned with the first magnet 121.

[0041] When the pulling spring 5 is in its natural state, the first plate body 41 drives the corresponding second plate body 42 to move to align with the first magnet 121. Then, the first magnet 121 adsorbs the corresponding second magnet 122, driving the second plate body 42 to move towards the direction close to the workbench 2, compressing the first pushing spring 6, thereby realizing the retracted state of the telescopic extension plate 4. When the first plate body 41 drives the second plate body 42 to slide away from the fixed plate 13, stretching the pulling spring 5, the first plate body 41 drives the second plate body 42 to gradually be misaligned with the corresponding first magnet 121 until the second magnet 122 disengages from the first magnet 121. At this time, the compressed first pushing spring 6 pushes the second plate body 42 to move away from the workbench 2, thereby realizing the extension of the telescopic extension plate 4.

[0042] Referring to Figure 3 and Figure 4 , a sliding plate 14 is slidably arranged on the workbench 2. The sliding plates 14 correspond to the telescopic extension plates 4 one by one. The sliding direction of the sliding plate 14 is parallel to the sliding direction of the corresponding telescopic extension plate 4. The telescopic extension plates 4, the corresponding fixed plates 13, and the corresponding sliding plates 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 at the upper ends of the plurality of 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 its natural state, the upper surface of the sliding plate 14 is lower than the upper surface of the second plate body 42. A sliding component for adjusting the sliding of the sliding plate 14 is arranged on the fixed plate 13.

[0043] Referring to Figure 3 and Figure 4 , for facilitating the adjustment of the sliding of the sliding plate 14, the sliding component includes a second pushing spring 15 and an adsorption moving part. The second pushing springs 15 correspond to the sliding plates 14 one by one. One end of the second pushing spring 15 is fixed on the corresponding fixed plate 13, and the other end is fixed on the corresponding sliding plate 14. The extending direction of the second pushing spring 15 is parallel to the sliding direction of the sliding plate 14. The second pushing spring 15 is used to push the corresponding sliding plate 14 to slide away from the fixed plate 13. The adsorption moving part is arranged on the first plate body 41 and is used to adsorb the sliding plate 14 to slide towards the direction close to the fixed plate 13.

[0044] Referring to Figure 3 and Figure 4, To facilitate the sliding of the adsorption sliding plate 14 towards the fixed plate 13, the adsorption moving member includes a third magnet 16 and a fourth magnet 17. The third magnet 16 is arranged on the first plate body 41 and is located below the second plate body 42, without interfering with the movement of the second plate body 42. An opening 21 for the third magnet 16 to pass through is formed on the fixed plate 13, and the cross-sectional area of the opening 21 is larger than that of the third magnet 16; the fourth magnet 17 is embedded in the sliding plate 14. The third magnet 16 is used to adsorb the fourth magnet 17 to drive the sliding plate 14 to slide 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 pushing spring 15; when the pulling spring 5 is in a natural state, the third magnet 16 and the fourth magnet 17 are in an adsorption and fixed state.

[0045] When the pulling spring 5 is in a natural state, the third magnet 16 and the fourth magnet 17 are adsorbed and fixed, compressing the second pushing spring 15, and the sliding plate 14 approaches the corresponding fixed plate 13. At this time, the entire flexible protective cover 3 is in a V-shaped retracted state.

[0046] When the first plate body 41 moves away from the fixed plate 13, the third magnet 16 separates from the corresponding fourth magnet 17. Then, the sliding plate 14 slides towards the metal workpiece under the action of the second pushing spring 15, so that the sliding plate 14 abuts against the metal workpiece, thereby expanding the flexible protective cover 3, which helps to collect chips and prevent the chips from accumulating on the workbench 2. After the processing is completed and the workbench 2 stops rotating, the first plate body 41 slides towards the fixed plate 13, so that the third magnet 16 passes through the opening 21 on the corresponding fixed plate 13. Then, the third magnet 16 adsorbs the corresponding fourth magnet 17 to drive the sliding plate 14 to slide towards the fixed plate 13 until the third magnet 16 and the fourth magnet 17 are in adsorption cooperation, and the sliding plate 14 approaches the corresponding fixed plate 13. At this time, the entire flexible protective cover 3 returns to the V-shaped retracted state, which is convenient for collecting chips, facilitating subsequent processing, and not easily polluting the surrounding environment or the workbench 2.

[0047] Refer to Figure 3 and Figure 4, for facilitating the adaptation to a conical rotary metal workpiece, the sliding plate 14 includes a sliding seat 141 and a fitting plate 142. The sliding seat 141 is slidably connected to the surface of the workbench 2, and the sliding direction of the sliding seat 141 is parallel to the sliding direction of the corresponding first plate body 41. One end of the second pushing spring 15 away from the fixed plate 13 is fixed to the sliding seat 141 of the corresponding sliding plate 14; the fitting plate 142 is hinged to the sliding seat 141, the hinge axis of the fitting plate 142 is perpendicular to the sliding direction of the sliding seat 141, a torsion spring 20 is sleeved on the hinge shaft of the fitting plate 142, one end of the torsion spring 20 is fixed to the sliding seat 141, and the other end is fixed to the fitting plate 142. The torsion spring 20 is used to drive the fitting plate 142 to rotate in a direction away from the fixed plate 13. The fourth magnet 17 is embedded in the surface of the fitting plate 142 close to the fixed plate 13, and the cross-sectional area of the fourth magnet 17 is larger than the cross-sectional area of the third magnet 16; the adsorption force between the third magnet 16 and the fourth magnet 17 is greater than the sum of the torsion force of the torsion spring 20 and the thrust of the second pushing spring 15. When the torsion spring 20 is in a natural state, the included angle between the surface of the fitting plate 142 away from the fixed plate 13 and the surface of the workbench 2 is greater than 60 degrees; the torsion force of the torsion spring 20 is less than the thrust of the second pushing spring 15; a limiting plate 22 is fixed to the surface of the sliding seat 141 close to the fixed plate 13. When the fitting plate 142 abuts against the limiting plate 22, the fitting plate 142 is in a vertical state; when the pulling spring 5 is in a natural state, the third magnet 16 and the fourth magnet 17 are in an adsorption fit, and the fitting plate 142 is in a vertical state.

[0048] When the first plate body 41 moves in a direction away from the fixed plate 13, the third magnet 16 is separated from the corresponding fourth magnet 17. Then, the sliding seat 141 slides in the direction close to the metal workpiece under the action of the second pushing spring 15. Then, the fitting plate 142 rotates in the direction away from the fixed plate 13 under the action of the torsion spring 20, so that the upper end of the fitting plate 142 abuts against the metal workpiece, thereby expanding the flexible protective cover 3, which helps to ensure the chip collection effect on the conical metal workpiece.

[0049] The implementation principle of the embodiment of the present 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 an initial state, that is, the pulling spring 5 is in a natural state, the first magnet 121 and the second magnet 122 are in an adsorption and fixed state, the third magnet 16 and the fourth magnet 17 are in an adsorption and fixed state, and the flexible protective cover 3 is in a retracted state.

[0050] Next, drive the rotating mechanism to drive the workbench 2 and the metal workpiece on the workbench 2 to rotate. The counterweight ball 19 will drive the extension rod 8 and the abutting strip 9 to move away from the support rod 7 under the action of centrifugal force. Then, multiple abutting strips 9 will push multiple first plate bodies 41 to move away from the metal workpiece. Next, the first magnet 121 will disengage from the corresponding second magnet 122, and the third magnet 16 will disengage from the corresponding fourth magnet 17. Then, the compressed first pushing spring 6 will push the second plate body 42 to move away from the workbench 2. Multiple second plate bodies 42 will drive the flexible protective cover 3 to unfold upward and outward, moving the outside of the flexible protective cover 3 outside the turning tool head and the milling head. The sliding seat 141 will slide toward the metal workpiece under the action of the second pushing spring 15. Then, the attaching plate 142 will rotate away from the fixing plate 13 under the action of the torsion spring 20, so that the upper end of the attaching plate 142 abuts against the metal workpiece, and further the flexible protective cover 3 will unfold inward, making the entire flexible protective cover 3 in a V-shaped unfolded state. Thus, when the turning tool head and / or the milling head processes the metal workpiece, the flexible protective cover 3 can block the chips splashed under the action of centrifugal force to a certain extent and collect them, which helps to reduce potential safety hazards.

[0051] When the processing of the metal workpiece is completed and the workbench 2 stops rotating, the counterweight ball 19 is no longer affected by centrifugal force. Then, under the pulling of the elastic rope 11, the extension rod 8 moves toward the support rod 7, reducing the abutting force of the abutting strip 9 on the first plate body 41 until the abutting strip 9 at the end of the extension rod 8 disengages from the first plate body 41. At this time, the first plate body 41 moves toward the fixing plate 13 under the action of the pulling spring 5. Then, the first plate body 41 resets to its initial state, the second magnet 122 aligns with the first magnet 121, and the first magnet 121 adsorbs the corresponding second magnet 122 to drive the second plate body 42 to move toward the workbench 2, compressing the first pushing spring 6, thereby realizing the retracted state of the telescopic extension plate 4. The third magnet 16 passes through the corresponding opening 21 and will first adsorb the fourth magnet 17 to make the attaching plate 142 rotate toward the fixing plate 13 to a vertical state and abut against the limiting plate 22. Then, it continues to adsorb the fourth magnet 17, making the sliding seat 141 slide toward the fixing plate 13 until the third magnet 16 and the fourth magnet 17 are completely adsorbed and matched. At this time, the sliding seat 141 is close to the corresponding fixing plate 13, and the entire flexible protective cover 3 returns to a V-shaped retracted state, which helps to collect the chips, facilitates subsequent processing, and is not likely to pollute the surrounding environment or the workbench 2.

[0052] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
