Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of machine tool processing, and particularly relates to a multifunctional machine tool for sheet metal part processing. BACKGROUND

[0002] In the existing sheet metal manufacturing, a multifunctional processing machine tool integrating punching, cutting, tapping, riveting and even simple bending is widely used, which usually adopts a support nail matrix (also known as a spike array) as a workpiece bearing platform. The structure is composed of hundreds to thousands of high-hardness support nails to form a point-shaped support surface, which has the advantages of permeable space below, facilitating unobstructed penetration processing of tools or lasers, and is particularly suitable for complex multi-hole or special-shaped sheet metal parts. However, in actual use, the support nail matrix has obvious defects: Firstly, when laser cutting is performed on plate or profile workpieces, such workpieces are generally placed and positioned on the support nails on the nail bed surface. During cutting, high-temperature molten metal is blown away from the cutting gap by auxiliary gas, and part of the splashed slag and high-temperature debris will quickly cool and adhere to the surface of the nail body or the gap between the nail array around the cutting area. With continuous operation of the equipment, these adhesions continuously accumulate, not only changing the local support height, but also damaging the flatness of the nail array as a whole. When subsequent workpieces are placed thereon, a slight tilt or local suspension is generated due to the misalignment of the support reference, directly affecting the laser focal point position and cutting perpendicularity, ultimately leading to processing defects such as contour size out-of-tolerance and cross-section quality decline.

[0003] Secondly, the metal curl produced by punching, the slag formed by laser cutting and the fine dust are extremely easy to be stuck in the narrow gap of the dense nail array. Especially when processing thin plate workpieces with a large number of small holes, the punching waste is often circular or annular, with a size matching the nail gap, which is extremely easy to embed in the dead angle of the nail root and difficult to slide down naturally by gravity.

[0004] Finally, the traditional nail matrix is a fixed structure and cannot be locally adjusted according to the size, thickness or process requirements of the sheet metal part (such as avoiding bending lines and strengthening edge support), which has poor adaptability. More importantly, waste cleaning or nail array maintenance must be carried out in the stopped state, and the equipment cannot be used during the processing period, which seriously affects the production continuity and automation efficiency. SUMMARY

[0005] Therefore, the present application aims to provide a multifunctional machine tool for sheet metal part processing to solve the problems existing in the background art.

[0006] In order to solve the above technical problems, the technical scheme of the present application is a multifunctional machine tool for sheet metal machining, comprising a machining platform, a plurality of support nails for supporting the sheet metal to be machined are arranged on the machining platform, the support nails are arranged in a linear array and constitute a support row which can be independently adjusted; the distance between the support rows on the machining platform is adjusted to adapt to the machining requirements of different sheet metals to be machined, and after machining is completed, the gap between the support rows is increased to effectively reduce the waste jamming; the machining platform is provided with support nails on both the front and back surfaces, the machining platform is turned over by 180° as a whole or partially to switch the working surface of the two support nails; when one side of the support nail is affected by the use of adhering slag, wear or accumulation of chips, it is switched to the other side for continuous operation, and the turning action is used to assist in dumping the residual waste.

[0007] Preferably, the machining platform comprises a base, a plurality of rotating members are arranged on the base in an equidistant manner, each rotating member is independently rotatably installed on the base; the support rows are installed on both sides of the rotating members in a symmetrical manner, so that after the rotating members are turned over, the support rows on the rotating members can switch the working surface; the overall turning of the machining platform is decomposed into the independent rotation of a plurality of local rotating members, which significantly reduces the movement space and rotating radius required for single turning.

[0008] Further, a sliding seat is arranged between the base and the rotating member, the sliding seat is slidably arranged on the base, and the sliding seat and the rotating member are rotatably connected through a rotating shaft or a bearing structure; by driving the sliding seat to move on the base, the rotating member and the support rows on the rotating member can be translated as a whole, so as to adjust the distance between adjacent support rows to adapt to the machining requirements of sheet metal parts of different sizes or structures; at the same time, the sliding seat can be pre-moved to a reserved avoidance position before the rotating member performs a 180° turning action, so as to provide sufficient movement space for the rotation of the rotating member.

[0009] Further, a ball screw is arranged on the base, the ball screw extends in the sliding direction and is provided with a plurality of moving members matched therewith, the moving members are fixedly connected with the sliding seat; by driving the ball screw to rotate, each moving member is synchronously moved in the axial direction, so as to control the position of the sliding seat on the base and realize the distance adjustment of the support rows.

[0010] Further, the base is provided with a guide rail for guiding the movement of the sliding seat, a rack is fixedly arranged on the base in the sliding direction, a driving gear is installed on the sliding seat, and the driving gear is engaged with the fixed rack; by driving the driving gear to rotate, the sliding seat is linearly moved on the base along the guide rail, so as to realize the position adjustment of the support rows.

[0011] Further, the sliding seat is equipped with a separate driving motor, the output shaft of the driving motor is in transmission connection with the rotating member, and the driving motor is used to drive the rotating member to rotate; through the driving motor, 180° accurate overturning control of a single or multiple rotating members is realized, so that the working states of the upper and lower two support rows are switched; the driving motors on the sliding seats can be started and stopped individually or synchronously linked, so that the support area has flexibility of local overturning and cleaning or overall surface changing operation.

[0012] Further, the base is provided with a synchronous component for driving the rotating member to overturn, the synchronous component comprises a driving shaft extending along the moving direction of the sliding seat, and the driving shaft is rotatably installed on the base; a transmission assembly is sleeved on the driving shaft in sliding fit, the transmission assembly is rotatably installed on the sliding seat and is in transmission connection with the rotating member; when the sliding seat moves along the base to adjust the spacing between the support rows, the transmission assembly slides synchronously with the sliding seat in the axial direction of the driving shaft, and always maintains effective fit with the driving shaft; when it is necessary to overturn the support rows, the driving shaft is rotated, torque is transmitted to the rotating member through the transmission assembly, so that the rotating member is driven to rotate 180° around its own axis.

[0013] Further, the transmission assembly comprises a fixed member rotatably installed on the sliding seat and in transmission connection with the rotating member, and a transmission member sleeved on the driving shaft in sliding fit; the fit surfaces of the driving shaft and the transmission member are respectively provided with a transmission groove and a transmission protrusion matched with each other, so that the transmission member can rotate synchronously with the driving shaft while sliding in the axial direction of the driving shaft; the fixed member and the transmission member are both gear components, and always maintain meshing state; when the driving shaft is rotated, power is transmitted to the transmission member through the transmission protrusion and the transmission groove, and then the torque is reliably transmitted to the rotating member through the gear meshing of the transmission member and the fixed member, so that the rotating member is driven to complete 180° overturning.

[0014] Further, the fixed member and the transmission member are bevel gear transmission components, the fixed member and the transmission member are arranged in intersecting shaft mode, and the included angle between the axes of the fixed member and the transmission member is 90°; the fixed member and the transmission member are both conical bevel gears, the transmission member is sleeved on the driving shaft in sliding fit through its own inner hole, and synchronous rotation is realized through the cooperation of the transmission groove and the transmission protrusion on the driving shaft; the fixed member is rotatably installed on the sliding seat and is coaxially connected with the rotating member; when the driving shaft is rotated, power is transmitted to the fixed member through the transmission member, the direction of movement is changed by 90° through bevel gear meshing, so that the rotating member is driven to overturn around its own horizontal axis.

[0015] Further, the fixing member and the transmission member constitute a worm and gear transmission pair, the fixing member and the transmission member are arranged in a space staggered shaft, the fixing member is a worm, the fixing member is rotatably installed on the sliding seat and coaxially fixedly connected with the rotating member, the transmission member is a worm, the transmission member is slidably sleeved on the driving shaft and is matched with the transmission groove through the transmission protrusion on the driving shaft and rotates synchronously with the driving shaft, when the driving shaft rotates, the worm drives the worm to rotate, and then drives the rotating member to complete 180° overturning.

[0016] The technical effects of the present application mainly embody in the following aspects: The present application reconfigures the traditional fixed nail array into a plurality of linearly arranged support rows, each row is installed on the base through the sliding seat and is driven to realize independent or synchronous translation by the ball screw or the gear and rack. This design makes the support density dynamically adjustable according to the workpiece size, thickness and hole distribution. For example, the support density is increased at the edge of the thin plate to suppress warping, and the gap is enlarged in the multi-hole area to facilitate the falling of waste. Thus, the support system is upgraded from "passive bearing" to "active adaptation", effectively improving the clamping stability and machining consistency, and solving the problem of insufficient support or interference caused by the rigid layout of the traditional nail array.

[0017] The present application differs from the heavy overall worktable overturning scheme, and the overturning function is decomposed into a plurality of small rotating member units, each unit has light weight and small rotating radius, and the required avoidance space is extremely small. This not only avoids the interference with the periphery structure such as the bed body and the waste channel, but also reduces the driving power and inertia impact; at the same time, the support rows with consistent structure are symmetrically arranged on both sides of each rotating member, forming double working surfaces. When one surface is affected by precision due to slag adhesion, debris accumulation or wear, manual cleaning or machine shutdown is not required, and only the corresponding rotating member needs to be overturned by 180°, so that the clean surface can continue to work. During the overturning process, gravity assists the falling of residual waste, realizing "changing surface to clean waste".

[0018] The present application sets up bearing connection between the sliding seat and the rotating member, integrates the transmission assembly on the sliding seat, and makes the assembly and the driving shaft on the base keep continuous engagement through the sliding transmission member; it is ensured that no matter what the adjusting position of the sliding seat is, the overturning driving link is always effective. This "translation-rotation decoupling but continuous transmission" design solves the technical problem of easy disconnection of power transmission on the moving part, and is the key to realize the unity of high flexibility and high reliability. Two preferred schemes of bevel gear intersecting shaft transmission and worm and gear staggered shaft transmission are provided: the bevel gear transmission has high efficiency and fast response, and is suitable for high frequency overturning; the worm and gear has self-locking characteristics, and can prevent accidental deflection when power is off or subjected to external force, thereby improving safety. Both schemes support centralized driving and multi-point synchronization, which not only ensures the consistency of action, but also can be flexibly selected according to the load, precision or safety level, and embodies high engineering practicability.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0021] The multi-functional machine tool for sheet metal processing provided by this invention is mainly used in the field of composite processing of hardware sheet metal parts, and is especially suitable for highly flexible manufacturing scenarios that integrate punching, laser cutting, tapping, riveting, and simple bending. However, it is not limited to this and can also be widely used in the processing of other plate or thin-walled structural parts with similar support, positioning, and self-cleaning requirements.

[0022] Furthermore, as is common knowledge in this industry, the technologies mentioned above, such as ball screw 121 transmission, gear and rack transmission, bevel gear intersecting shaft transmission, worm gear intersecting shaft transmission, linear guide 131 guidance, motor closed-loop control, and PLC or CNC control system for coordinating and scheduling multi-axis motion, are all mature technologies in the fields of mechanical automation and CNC equipment. The above content pertains to technically skilled individuals and is routinely used; therefore, its specific working principles and internal structures will not be elaborated upon further.

[0023] Example 1 Traditional multi-functional machine tools consist of a bed, worktable, X / Y / Z three-axis motion system, composite machining units (such as punching devices, laser cutting heads, tapping mechanisms, and riveting modules), control system, and a fixed support pin matrix platform. The worktable typically uses a rigid welded or cast iron structure, on which densely arranged and fixedly positioned support pins 111 form a point-bearing surface, ensuring unobstructed space beneath the workpiece for penetrating machining by cutting tools or laser beams. However, this support structure is a static, non-adjustable design, unable to dynamically adjust the support layout according to workpiece size, thickness, or process path, and lacks self-cleaning capabilities. During prolonged operation, punching waste, laser slag, and metal dust easily become embedded in the pin matrix gaps, difficult to remove, leading to deterioration of the support surface flatness. Furthermore, maintenance and cleaning must be performed after machine shutdown, severely limiting the equipment's continuous operation capability and automation level. In addition, because the support pins 111 are constantly exposed to high temperatures, impacts, and abrasive particles, their tips are prone to wear or deformation, further affecting clamping stability and machining accuracy. Based on the above problems, this embodiment systematically reconstructs the traditional 111 matrix structure of support nails and proposes a multi-functional machine tool for sheet metal processing. Its core lies in achieving the adjustability, double-sided reusability, and local self-cleaning capability of the support structure. The specific technical solution is as follows: See Figure 1 , Figure 2 The machine tool includes a processing platform 1, on which support pins 111 for supporting sheet metal parts to be processed are arranged in a linear array, forming independently adjustable support rows. Each support row is spaced laterally, and its spacing is adjusted on the processing platform 1 by a drive mechanism, thus flexibly adapting to the processing needs of sheet metal parts of different sizes, thicknesses, and structural features. For example, when processing the edge areas of thin plates, the support can be densified to prevent warping; when processing porous areas, the spacing can be widened to allow for a channel for scrap material to fall. After processing, the gap between adjacent support rows can be actively increased, allowing small-sized punching scrap that is stuck to slide off naturally under gravity, significantly reducing manual intervention.

[0024] In some embodiments, see 3. Figure 4The processing platform 1 has symmetrically arranged support pins 111 of consistent height on both its front and back sides, forming a double working surface. When the support pin 111 on one side becomes inaccurate due to laser slag adhesion, metal debris accumulation, or tip wear, there is no need to stop the machine for replacement or cleaning. Instead, the unit containing the support pin is rotated 180° to quickly switch to another clean and intact working surface to continue operation. During the rotation, the original upward-facing support surface becomes downward-facing, and residual waste automatically falls off under the influence of gravity and slight vibrations during processing, achieving a synergistic effect of "changing surfaces and cleaning waste simultaneously".

[0025] Preferably, if the entire machining platform 1 is flipped over during the switching between dual working surfaces, it requires a large clearance space underneath, has a large moment of inertia, high drive power, and a complex structure, making it prone to interference with the bed, scrap channel, or surrounding moving parts. Furthermore, it demands extremely high repeatability after flipping, making it difficult to implement on compact multi-functional machine tools. In addition, the overall flipping interrupts operations in the entire working area, making localized scrap removal or zoned maintenance impossible, resulting in poor flexibility. In view of this, this embodiment does not adopt the cumbersome method of flipping the entire worktable, but instead modularizes and unitizes the flipping function into multiple independent rotating parts 113. The specific structure is as follows: The processing platform 1 includes a base 112, which is fixedly installed on the machine tool bed. Rotating parts 113 are arranged at equal intervals on the base 112. Each rotating part 113 is independently rotatably installed on the base 112 without interfering with each other and can perform rotational actions individually or synchronously. The support row is installed symmetrically on both sides of the rotating part 113 (that is, the front and back sides of the same rotating part 113 are provided with an array of support nails 111 with completely identical structure and height, forming two functionally equivalent working surfaces), so that after the rotating part 113 is flipped, the support row on the rotating part 113 can switch working surfaces.

[0026] When the support accuracy of a certain area is affected by laser slag adhesion, punching waste accumulation, or wear due to long-term use, the control system can switch the clean and intact support on the other side to the working position by simply driving the corresponding rotating component 113 to rotate precisely 180° around its own axis, thus updating the local working surface. Since the flipping action is limited to the small range of a single rotating component 113, the required clearance space below is minimal, allowing for seamless integration into existing compact equipment layouts. By transforming the traditional "overall flipping" into "multi-point local independent rotation," this embodiment significantly reduces the motion space and rotational inertia required for a single flip, lowering drive energy consumption and structural complexity. Simultaneously, it supports zoned, on-demand flipping—for example, flipping only the central waste-intensive area while leaving the edge areas in place for continued support—greatly improving equipment operating efficiency and process flexibility.

[0027] In some embodiments, to achieve the coordinated function of multi-point local independent rotation and dynamic adjustment of the support row spacing, this embodiment introduces a sliding seat 114 as a key intermediate connecting unit in its structure. This cleverly integrates translation and rotation degrees of freedom, solving the problem of conflict between "distance adjustment" and "flipping" in traditional solutions. Specifically, a sliding seat 114 is provided between the base 112 and the rotating component 113. The sliding seat 114 is slidably disposed on the base 112, and the sliding seat 114 and the rotating component 113 are reliably rotated through a rotating shaft, rolling bearing, or self-lubricating spherical bearing, so that the rotating component 113 can both translate as a whole with the sliding seat 114 and rotate independently around its own axis.

[0028] Based on the above structure, the system controls the position of the sliding seat 114 on the base 112 through a drive mechanism (such as a servo motor in conjunction with a ball screw 121 or a gear and rack transmission), thereby achieving a dual function: On the one hand, the spacing between the support rows can be adjusted to meet the needs of different workpieces. For example, when processing small-sized or thin-walled sheet metal parts, adjacent sliding seats 114 can be moved inward to reduce the spacing between the support rows, enhance the edge support rigidity, and prevent the workpiece from warping; when processing areas with dense small holes, the corresponding support rows can be pulled outward to increase the gap, providing a smooth falling channel for punching waste and laser slag, effectively avoiding jamming.

[0029] On the other hand, before performing the flipping action, the system automatically moves the target sliding seat 114 to a preset "flipping avoidance position," reserving sufficient space for the arc-shaped trajectory swept by its support row during the 180° rotation of the rotating component 113, completely avoiding mechanical interference with the base 112, vacuum chamber, waste slide, or other adjacent structures. After the flipping is completed, the sliding seat 114 returns to the working position set by the process, ensuring that the support layout meets the current processing requirements. Thus, this embodiment, by driving the sliding seat 114 to move on the base 112, can not only drive the rotating component 113 and the support row on the rotating component 113 to translate as a whole, thereby adjusting the distance between adjacent support rows to adapt to the processing requirements of sheet metal parts of different sizes or structures; it can also move the sliding seat 114 to the reserved avoidance position before the rotating component 113 performs the 180° flipping action, providing sufficient movement space for the rotation of the rotating component 113.

[0030] In some embodiments, regarding the drive mechanism for controlling the movement of the sliding seat 114 on the base 112, this embodiment provides two optional and complementary high-precision transmission schemes to adapt to the differentiated requirements of rigidity, speed, load, and maintainability under different working conditions. Both drive methods can achieve independent adjustment of a single sliding seat 114 or synchronous adjustment of multiple sliding seats 114 through a CNC system, and support linkage with CAM process data to automatically generate the optimal support row layout based on the workpiece contour. Simultaneously, before flipping, the control system can automatically move the designated sliding seat 114 to a preset avoidance position to ensure safe and interference-free subsequent rotational movements.

[0031] The first option uses a ball screw 121 transmission structure: see [link / reference] Figure 3 A high-precision ball screw 121 is mounted on the base 112 along the sliding direction. This screw is driven to rotate by a servo motor. Several nut-type moving parts 122 are fitted on the screw, and each moving part 122 is rigidly fixedly connected to a corresponding sliding seat 114. When the servo motor drives the ball screw 121 to rotate, each moving part 122 moves synchronously and precisely along the screw axis, thereby driving all sliding seats 114 and their rotating parts 113 to translate as a whole with the support row. This solution has the advantages of high transmission rigidity, excellent repeatability, and no backlash, and is particularly suitable for precision sheet metal processing scenarios with strict requirements for the consistency of the support row layout, such as high-precision assembly products like communication chassis and medical equipment housings.

[0032] The second option uses a gear-rack 132 transmission structure: see [link / reference] Figure 4 A high-hardness quenched rack 132 is fixedly mounted on the base 112 along the sliding direction and equipped with a high-parallelism linear guide rail 131 for guidance. A drive gear 133 is integrated at the bottom of the sliding seat 114. This gear is driven by an independent servo motor or stepper motor and maintains constant meshing with the fixed rack 132 on the base 112. When the motor rotates, the drive gear 133 rolls along the rack 132, pushing the sliding seat 114 to move smoothly and linearly along the guide rail 131. This structure has advantages such as simple structure, unrestricted stroke, strong dust resistance, and easy modular expansion. It is especially suitable for applications with large worktables, long stroke adjustment, or multi-area asynchronous distance adjustment, such as the flexible processing of large electrical control cabinets or new energy equipment supports.

[0033] In some embodiments, based on the flexible adjustment of the support row spacing, this embodiment specifically designs a highly efficient, precise, and highly controllable flipping drive system to address the requirements of support row working surface switching and self-cleaning. Specifically, the sliding seat 114 is equipped with an independent drive motor, which is directly mounted on the sliding seat 114 body. The output shaft of the drive motor is connected to the rotating component 113 via a coupling, transmission shaft, or gear pair. The drive motor is used to drive the rotating component 113 to rotate. The drive motor is preferably a servo motor with an absolute encoder or a high-torque stepper motor, which has the capability of closed-loop position control. When it is necessary to switch the support surface, the drive motor can achieve 180° precise flipping control of one or more rotating components 113, thereby switching the working state of the upper and lower support rows. The drive motors on each sliding seat 114 can be started and stopped individually or linked synchronously, giving the support area the flexibility of partial flipping for waste removal or overall surface replacement. This independent drive configuration enables precise area management: for example, only a few sets of rotating parts 113 in the densely punched central area can be flipped and cleaned, while the edge areas remain in place to continue supporting the workpiece, avoiding unnecessary overall movement; alternatively, after the entire batch of processing is completed, all drive motors can be started synchronously to achieve one-click surface changing of the entire working surface, preparing a clean support benchmark for the next batch of operations. The drive motors on each sliding seat 114 can be started and stopped individually to achieve "on-demand flipping," or they can be synchronously linked through a PLC or motion controller to ensure phase consistency and time synchronization of multi-point flipping, preventing misalignment of the support surface due to asynchronous movements.

[0034] In some embodiments, see Figure 5 , Figure 6To simplify and ensure the flipping drive of the support row, synchronous flipping control of multiple rotating components 113 is achieved. This embodiment employs an innovative synchronous transmission system. Specifically, a synchronous component 141 for driving the rotating components 113 to flip is provided on the base 112. The synchronous component 141 includes a drive shaft 142 extending along the moving direction of the sliding seat 114. The drive shaft 142 is rotatably mounted on the base 112. Multiple transmission components are slidably fitted on the drive shaft 142. The transmission components are rotatably mounted on the sliding seat 114 and are connected to the rotating components 113 in a transmission manner. When the sliding seat 114 moves along the base 112 to adjust the spacing of the support rows, the transmission components slide synchronously with the sliding seat 114 in the axial direction of the drive shaft 142, always maintaining effective cooperation with the drive shaft 142. When it is necessary to flip the support row, the drive shaft 142 rotates, and the torque is transmitted to the rotating components 113 through the transmission components, thereby driving the rotating components 113 to rotate 180° around their own axis. This ensures that no matter how the sliding seat 114 moves along the base 112 to adjust the spacing of the support rows, the transmission assembly can always maintain effective cooperation with the drive shaft 142, ensuring uninterrupted power transmission. The transmission assembly includes a fixed member 143 rotatably mounted on the sliding seat 114 and connected to the rotating member 113, the fixed member 143 being responsible for transmitting torque to the rotating member 113; and a transmission member 144 slidably sleeved on the drive shaft 142, the mating surfaces of the drive shaft 142 and the transmission member 144 being respectively provided with mutually matching transmission grooves and transmission protrusions, so that the transmission member 144 can rotate synchronously with the drive shaft 142 while sliding along the axial direction of the drive shaft 142; both the fixed member 143 and the transmission member 144 are gear components, and the two always remain in a meshing state; when the drive shaft 142 rotates, the power is transmitted to the transmission member 144 via the transmission protrusion and transmission groove, and then the torque is reliably transmitted to the rotating member 113 through the gear meshing between the transmission member 144 and the fixed member 143, thereby driving the rotating member 113 to complete a 180° rotation.

[0035] Regarding option one for the aforementioned fixing member 143 and transmission member 144: See [link / reference needed] Figure 5The fixing member 143 and the transmission member 144 are bevel gear transmission components, arranged with intersecting axes and an included angle of 90°. Both the fixing member 143 and the transmission member 144 are bevel bevel gears. The transmission member 144 is slidably sleeved on the drive shaft 142 through its inner hole and rotates synchronously with the transmission protrusion on the drive shaft 142 through a transmission groove. The fixing member 143 is rotatably mounted on the sliding seat 114 and coaxially connected to the rotating member 113. When the drive shaft 142 rotates, the power is transmitted to the fixing member 143 through the transmission member 144, changing the direction of motion by 90° through the meshing of the bevel gears, thereby driving the rotating member 113 to rotate around its own horizontal axis. The bevel gear transmission has the characteristics of high efficiency, smoothness, and high load-bearing capacity, and is suitable for high-frequency flipping operations. Its compact layout makes it particularly suitable for space-constrained applications.

[0036] Regarding option two for the aforementioned fixing member 143 and transmission member 144: See [link / reference] Figure 6 The fixed component 143 and the transmission component 144 constitute a worm gear transmission pair, with the fixed component 143 and the transmission component 144 arranged in a spatially staggered axis configuration. The fixed component 143 is a worm gear, rotatably mounted on the sliding seat 114 and coaxially fixedly connected to the rotating component 113. The transmission component 144 is a worm, slidably sleeved on the drive shaft 142, and engages with the transmission groove via a transmission protrusion on the drive shaft 142, rotating synchronously with the drive shaft 142. When the drive shaft 142 rotates, the worm drives the worm wheel to rotate, thereby driving the rotating component 113 to complete a 180° rotation. The worm gear transmission has a self-locking characteristic, effectively preventing the rotating component 113 from rotating unexpectedly due to gravity or external forces in the event of a power outage or shutdown, thus improving system safety and positioning stability. In addition, the worm gear transmission also has a high transmission ratio, enabling the achievement of a large output torque with a small driving torque, making it suitable for heavy-duty applications.

[0037] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

Support rows are installed on both sides of the rotating components in a vertically symmetrical manner, so that the working surface can be switched by the support rows on the rotating components after the rotating components are flipped. The entire processing platform is flipped and decomposed into the independent rotation of multiple local rotating parts, which significantly reduces the motion space and rotation radius required for a single flip.

3. The multi-functional machine tool for sheet metal processing as described in claim 2, characterized in that: A sliding seat is provided between the base and the rotating component. The sliding seat is slidably disposed on the base, and the sliding seat and the rotating component are rotatably connected by a rotating shaft or bearing structure. By driving the sliding seat to move on the base, not only can the rotating component and the support row on the rotating component be translated as a whole, thereby adjusting the distance between adjacent support rows to adapt to the processing requirements of sheet metal parts of different sizes or structures; at the same time, before the rotating component performs a 180° flipping action, the sliding seat can be pre-moved to a reserved avoidance position, providing sufficient movement space for the rotation of the rotating component.

4. The multi-functional machine tool for sheet metal processing as described in claim 3, characterized in that: A ball screw is provided on the base, the ball screw extends along the sliding direction and is equipped with a number of moving parts that cooperate with it, and the moving parts are fixedly connected to the sliding seat. By driving the ball screw to rotate, each moving part moves synchronously along the axial direction, thereby controlling the position of the sliding seat on the base and realizing the adjustment of the spacing of the support row.

5. The multi-functional machine tool for sheet metal processing as described in claim 3, characterized in that: The base is equipped with a guide rail for guiding the movement of the sliding seat, a rack is fixedly arranged on the base along the sliding direction, and a drive gear is installed on the sliding seat, the drive gear meshing with the fixed rack; By driving the drive gear to rotate, the sliding seat moves linearly along the guide rail on the base, thereby achieving position adjustment of the support row.

6. The multi-functional machine tool for sheet metal processing as described in claim 4 or 5, characterized in that: The sliding seat is equipped with an independent drive motor, the output shaft of the drive motor is connected to the rotating component, and the drive motor is used to drive the rotating component to rotate. The drive motor enables precise 180° rotation control of one or more rotating parts, thereby switching the working state of the upper and lower support rows; the drive motors on each sliding seat can be started and stopped individually or linked synchronously, giving the support area the flexibility to perform partial rotation for waste removal or overall surface replacement.

7. The multi-functional machine tool for sheet metal processing as described in claim 4 or 5, characterized in that: The base is provided with a synchronizing component for driving the rotating component to rotate. The synchronizing component includes a drive shaft extending along the moving direction of the sliding seat. The drive shaft is rotatably mounted on the base. A transmission assembly is slidably fitted on the drive shaft. The transmission assembly is rotatably mounted on the sliding seat and is connected to the rotating component in a transmission manner. When the sliding seat moves along the base to adjust the spacing of the support rows, the transmission assembly slides synchronously with the sliding seat in the axial direction of the drive shaft, always maintaining effective cooperation with the drive shaft; when it is necessary to flip the support rows, the drive shaft rotates, and the torque is transmitted to the rotating component through the transmission assembly, thereby driving the rotating component to rotate 180° around its own axis.

8. The multi-functional machine tool for sheet metal processing as described in claim 7, characterized in that: The transmission assembly includes a fixed member rotatably mounted on the sliding seat and connected to the rotating member in a transmission manner, and a transmission member slidably sleeved on the drive shaft; the mating surfaces of the drive shaft and the transmission member are respectively provided with mutually matching transmission grooves and transmission protrusions, so that the transmission member can rotate synchronously with the drive shaft while sliding along the drive shaft axial direction. Both the fixing component and the transmission component are gear components, and they are always in a meshing state. When the drive shaft rotates, the power is transmitted to the transmission component through the transmission protrusion and the transmission groove. Then, through the meshing of the gears of the transmission component and the fixing component, the torque is reliably transmitted to the rotating component, thereby driving the rotating component to complete a 180° rotation.

9. The multi-functional machine tool for sheet metal processing as described in claim 8, characterized in that: The fixing component and the transmission component are bevel gear transmission components. The fixing component and the transmission component are arranged with intersecting axes, and the included angle between their axes is 90°. Both the fixing component and the transmission component are bevel gears. The transmission component is slidably sleeved on the drive shaft through its own inner hole and rotates synchronously with the transmission protrusion on the drive shaft through the transmission groove. The fixing component is rotatably mounted on the sliding seat and coaxially connected to the rotating component. When the drive shaft rotates, the power is transmitted to the fixed part through the transmission component. The direction of motion is changed by 90° through the meshing of the bevel gear, thereby driving the rotating part to rotate around its own horizontal axis.

10. The multi-functional machine tool for sheet metal processing as described in claim 8, characterized in that: The fixing component and the transmission component constitute a worm gear transmission pair, and the fixing component and the transmission component are arranged in a spatially staggered axis arrangement; The fixing component is a worm gear, which is rotatably mounted on the sliding seat and coaxially fixedly connected to the rotating component; the transmission component is a worm, which is slidably sleeved on the drive shaft and cooperates with the transmission groove through the transmission protrusion on the drive shaft, and rotates synchronously with the drive shaft. When the drive shaft rotates, the worm drives the worm wheel to rotate, which in turn drives the rotating parts to complete a 180° rotation.
