Description

Technical Field

[0001] The present invention relates to the technical field of machining tables, and particularly to a double-column movable-beam single-station high-speed turnover worktable. Background Art

[0002] Traditional numerical control machine tools, such as three-axis machining centers, can complete a large number of machining tasks. However, for workpieces that require machining from multiple angles, such as boxes, valve bodies, impellers and the like in aerospace and automotive parts, operators are often required to perform multiple clamping and repositioning. Each clamping not only consumes a large amount of time and labor, but also may introduce new positioning errors, thereby affecting the machining accuracy and surface quality of the final product.

[0003] To solve the problems of efficiency and accuracy in multi-surface machining, a common solution is to use a worktable with a turnover function. For example, some simple turnover worktables are driven by hydraulic or pneumatic devices, which can realize 90-degree or 180-degree turnover of workpieces. However, such turnover worktables generally have the following defects: firstly, the turnover speed is relatively slow, which is difficult to meet the demands of modern high-speed machining; secondly, the turnover positioning accuracy is not high, and additional locking mechanisms are often required to ensure the stability during machining, but the locking mechanisms themselves may also introduce errors or increase the turnover time; furthermore, such turnover worktables are usually independent units, which have low integration with the machining axes (X, Y, Z axes) of the machine tool, and have limitations in data transmission and cooperative control, making it difficult to realize true linked machining. In addition, many turnover worktables lack consideration for maintenance convenience during design. When the turnover mechanism or its driving components fail, large-scale disassembly of the machine tool is required, which is time-consuming and labor-intensive, and seriously affects the availability of the equipment. Especially in a single-station high-speed machining environment, any downtime for maintenance means huge production losses. Summary of the Invention

[0004] The present invention solves the problems in the related art, and proposes a double-column movable-beam single-station high-speed turnover worktable, which solves the problems of poor flexibility and inconvenient maintenance of the existing machine tool turnover worktables during use.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: a double-column moving beam single-station high-speed tilting worktable, comprising a bed body, a Y-axis movable seat slidably mounted on the upper end surface of the bed body, a first driving component for moving the Y-axis movable seat is also provided on the bed body, an X-axis movable seat is slidably mounted on the Y-axis movable seat, and a second driving component for moving the X-axis movable seat is also installed on the Y-axis movable seat, a Z-axis movable seat is slidably mounted on the front end of the X-axis movable seat, a third driving component for raising and lowering the Z-axis movable seat is provided on the X-axis movable seat, and a processing component is fixedly mounted on the lower end of the Z-axis movable seat; a tilting worktable is rotatably mounted in the bed body, and a control component for adjusting the rotation of the tilting worktable is also provided in the bed body; The flip-type worktable includes a boat-shaped base, a device table, and a drive assembly. The boat-shaped base is located in a concave shell near the front end, and both ends of the boat-shaped base are rotatably mounted in positioning shaft seats. The device table is rotatably mounted at the center of the upper end face of the boat-shaped base. The drive assembly is fixedly mounted in the boat-shaped base and is used to drive the device table to rotate. The boat-shaped base includes a horizontal base, a bent pendulum base, and a horizontal shaft that mates with the positioning shaft base. The horizontal base has a central slot at its center for mounting the equipment platform and drive components. The bent pendulum bases are symmetrically arranged at both ends of the horizontal base and are integrally formed with the horizontal base. The horizontal shaft is inserted into the head of the bent pendulum base and is fixedly connected to the bent pendulum base.

[0006] By adopting the above technical solution, and integrating multi-axis linkage Y-axis movable seats, X-axis movable seats, Z-axis movable seats and their driving components, along with the machining components fixedly mounted at the lower end, this invention constructs a highly flexible and precise three-dimensional machining platform. This design enables the machining components to perform machining on arbitrarily complex curved surfaces or polyhedra of workpieces, greatly improving the flexibility and efficiency of machining, and reducing the positioning errors and time losses caused by multiple clamping in traditional machining. Simultaneously, the integration of the tilting worktable further expands the machining range of workpieces in a single clamping, achieving high-speed, high-efficiency, and high-precision multi-angle machining, significantly improving the automation level and production efficiency of the equipment. The structure of the tilting worktable includes a boat-shaped base, a machine table, and a driving component, specifying their installation positions and functions within the machine bed. The rotating installation of the boat-shaped base in the positioning axis seat provides the spindle for the tilting of the machine table. The rotating installation of the machine table on the boat-shaped base, in conjunction with the driving component, enables the workpiece to be precisely positioned and tilted at high speed at different angles. This multi-layered rotation design endows the worktable with extremely high flexibility, enabling multi-faceted machining without changing the workpiece clamping state, greatly improving processing efficiency and automation. The integrated molding or fixed connection of the horizontal platform, bent swing seat, and transverse axis ensures the structural strength and rigidity of the boat-shaped base itself. The central groove in the center of the horizontal platform provides integrated installation space for the equipment table and drive components. This compact structural design effectively reduces the overall volume, improves the stability of the tilting mechanism, and reduces rotational inertia, thereby supporting higher-speed tilting operations.

[0007] As a preferred embodiment, the bed body includes a bottom shell, a connecting front seat, a concave shell, and a moving beam seat. The connecting front seat and the bottom shell are respectively installed at the front and rear ends of the lower end face of the concave shell, and both the connecting front seat and the bottom shell are fixedly connected to the concave shell. The moving beam seat is fixedly installed on the rear end face of the concave shell. Positioning shaft seats for rotating and installing a flip-type worktable are provided on both sides of the concave shell, and the positioning shaft seats are fixedly connected to the concave shell.

[0008] By adopting the above technical solution, the internal structure of the machine bed, including the bottom shell, connecting front seat, concave shell, and moving beam seat, is fixedly connected to ensure the high rigidity and stability of the entire machine bed. In particular, the positioning shaft seats on both sides of the concave shell provide precise support points for the stable rotation of the tilting worktable. This modular and robust structural design effectively disperses the stress generated during machining, reduces the impact of vibration on machining accuracy, and provides a solid and reliable foundation for the upper moving parts and the tilting mechanism.

[0009] As a preferred embodiment, the Y-axis movable seat includes a double-headed horizontal seat and a first guide seat for sliding installation of the X-axis movable seat. Auxiliary rails for sliding installation of the double-headed horizontal seat are fixedly provided on both sides of the upper surface of the concave shell. The auxiliary rails are fixedly connected to the concave shell. The first guide seat is fixedly installed on the double-headed horizontal seat. The X-axis movable seat includes a sliding part and a second guide seat for installation of the Z-axis movable seat. The sliding part is slidably installed on the first guide seat, and the second guide seat is fixedly installed on the sliding part. The Z-axis movable seat includes a movable seat part and a vertical frame for fixed installation of the processing component. The movable seat part is slidably installed on the second guide seat, and the vertical frame is fixedly installed on the front end face of the movable seat part.

[0010] By adopting the above technical solution, the internal structure and sliding installation method of the Y-axis, X-axis, and Z-axis movable seats were refined. The double-headed cross seat of the Y-axis movable seat slides on the auxiliary rail, the sliding part of the X-axis movable seat slides on the first guide seat, and the moving part of the Z-axis movable seat slides on the second guide seat. This hierarchically nested sliding installation structure ensures the independence and high precision of each axis's movement. Through the design of the precision guide seat, friction and backlash during the movement process are effectively reduced, resulting in higher positioning and repeatability accuracy of each axis, providing a reliable motion foundation for the precision machining of complex workpieces.

[0011] As a preferred embodiment, the machining assembly includes a base, a machining motor, and a tool holder. The base is fixedly installed at the lower end of the vertical frame, the machining motor is fixedly installed in the base, and the tool holder is fixedly installed at the output end of the machining motor.

[0012] By adopting the above technical solution, the machining assembly includes a base, a machining motor, and a tool holder, which are fixedly installed at the lower end of the vertical frame of the Z-axis movable seat. This direct mounting method shortens the lever arm, improves machining rigidity, and reduces machining vibration. The machining motor directly drives the tool holder, achieving efficient power transmission and high-speed machining capabilities, meeting the needs of various materials and machining processes, and improving machining efficiency and surface quality.

[0013] As a preferred embodiment, the equipment platform includes a main platform, a plug-in ring seat, and a connecting sealing plate. The main platform has a central hole for mounting the drive assembly at its center, and a first locking groove is formed on the side of the central hole. The plug-in ring seat is fixedly installed at the center of the lower end face of the main platform and is integrally formed with the main platform. An external bearing that mates with the central groove is sleeved and fixed on the outer surface of the plug-in ring seat. The drive assembly includes a servo motor and a drive shaft. The servo motor is fixedly installed in a second locking groove corresponding to the first locking groove in the central groove. The drive shaft is fixedly connected to the output end of the servo motor, and a groove is formed at the head of the drive shaft. The connecting sealing plate is fixedly installed at the center of the main platform, and a connecting strip that mates with the first and second locking grooves is fixedly installed at the lower end of the connecting sealing plate.

[0014] By adopting the above technical solution, the main platform, plug-in ring seat, and connecting sealing plate of the equipment stage, together with the external bearing on the outer side of the plug-in ring seat, ensure the smoothness and high precision of the equipment stage's rotation on the boat-shaped base. The servo motor and drive shaft of the drive assembly, through the cooperation of the first locking groove, the second locking groove, and the connecting strip, achieve high torque, backlash-free power transmission and precise angular positioning. This precision connection and drive design ensures the stability and repeatability of the equipment during high-speed rotation and heavy-duty workpiece processing, thus improving processing quality.

[0015] As a preferred embodiment, the bottom shell includes a housing, a foot plate, a maintenance platform, and a mating housing for mounting the control components. The housing is fixedly installed on the lower end face of the concave shell, the foot plate is evenly fixed on the four corners of the lower end face of the housing, the maintenance platform is slidably installed in the housing, and a first electric cylinder for driving the maintenance platform to move to one side is also provided in the housing. The mating housing is fixedly installed on the upper end face of the maintenance platform, a drive screw is rotatably installed in the mating housing, and a control motor for controlling the forward and reverse rotation of the drive screw is fixedly installed at one end of the mating housing.

[0016] By adopting the above technical solutions, the sliding installation of the maintenance platform and the drive of the first electric cylinder provide a convenient and safe passage for internal maintenance of the equipment, allowing maintenance personnel to access key components without prolonged disassembly. The design of the drive screw and control motor within the housing provides precise mechanical driving force for the rotation adjustment of the tilting worktable.

[0017] As a preferred embodiment, the control component includes a movable seat block and a Y-shaped linkage frame. The movable seat block is slidably installed in the mating housing, and a threaded sleeve that mates with the drive screw is provided in the middle of the movable seat block. The lower end of the Y-shaped linkage frame is rotatably installed on the movable seat block. Two sets of guide shells are fixedly installed on both sides of the lower end face of the horizontal platform. An adjustable shaft group that is slidably connected to the head of the Y-shaped linkage frame is rotatably installed in each set of guide shells. The lower end face of the horizontal platform is also provided with a synchronous adjustment component for adjusting the distance between the two sets of adjustable shaft groups.

[0018] By adopting the above technical solution, the connection and adjustment mechanism between the control component and the tilting worktable through the moving seat block and the Y-type linkage frame is revealed. The moving seat block, in cooperation with the drive screw and threaded sleeve, converts the rotational motion of the control motor into precise linear displacement. The Y-type linkage frame then transmits this linear displacement to the adjustable shaft assembly of the tilting worktable, thereby realizing the rotational adjustment of the tilting worktable. Simultaneously, the guide shell and adjustable shaft assembly, along with the synchronous adjustment components located on the lower end face of the horizontal seat, not only ensure the accuracy of the tilting operation but also provide a quick and reliable disconnection mechanism during maintenance, improving the maintenance efficiency and safety of the equipment.

[0019] As a preferred embodiment, the guide shell includes a reinforcing base plate and a horizontal tube section. The reinforcing base plate is vertically fixed to the lower end face of the horizontal base. The horizontal tube section is fixedly installed at the lower end of the reinforcing base plate, and a guide groove is provided on one side of the horizontal tube section. The adjustable shaft assembly includes a plug-in shaft rod and an external connecting rod installed in the guide groove. The plug-in shaft rod is slidably installed in the horizontal tube section. One end of the external connecting rod is fixed to the plug-in shaft rod. The synchronous adjustment component includes a double-headed turntable, a linkage rod, and a second electric cylinder. The double-headed turntable is rotatably installed at the center of the lower end face of the horizontal base, and vertical shafts are fixedly installed on both sides of the lower end face of the double-headed turntable. One end of the linkage rod is rotatably connected to the vertical shaft, and the other end of the linkage rod is rotatably connected to the other end of the external connecting rod. The tail of the second electric cylinder is rotatably installed on the lower end face of the horizontal base, and the second electric cylinder is used to drive the double-headed turntable to rotate.

[0020] By adopting the above technical solution, the reinforced base plate and horizontal tube of the guide shell, in conjunction with the plug-in shaft and external connecting rod of the adjustable shaft assembly, ensure the stability of the tilting worktable when connected to the control components and the smooth sliding when disconnected. The synergistic action of the double-headed turntable, linkage rod, and second electric cylinder of the synchronous adjustment component achieves synchronous and precise adjustment of the two sets of adjustable shafts, thereby realizing reliable disengagement and connection with the Y-type linkage frame head. This precise synchronous adjustment mechanism enables the equipment maintenance work to be carried out safely and efficiently with minimal time and manpower, greatly improving the availability of the equipment.

[0021] Compared with the prior art, the beneficial effects of the present invention are: This invention constructs a high-precision multi-axis linkage machining platform through the linkage of the Y, X, and Z axis movable seats and their driving components on the main body of the machine bed. This design enables the machining components to accurately position and process workpieces at high speed in three-dimensional space, greatly improving the flexibility of machining and the ability to process complex workpieces. It reduces the number of clamping operations required in traditional multi-process operations, significantly improving machining efficiency and accuracy. The integration of machining components allows for multi-faceted machining to be completed in a single clamping, shortening the production cycle.

[0022] Secondly, the high-speed tilting worktable is integrated into the main body of the machine bed and precisely driven by control components, enabling rapid and accurate workpiece tilting during machining. This not only solves the pain point of repeated manual tilting in the machining of multifaceted workpieces, significantly improving the level of automation, but also avoids positioning errors and safety risks that may be caused by manual tilting. The design of the tilting mechanism ensures stability and repeatability under high-speed operation, further improving production efficiency and product quality.

[0023] Furthermore, the clever coordination between the maintenance platform and the first electric cylinder within the bottom housing, as well as the adjustable shaft assembly, synchronous adjustment components, and the second electric cylinder of the tilting worktable and control components, allows operators to easily and quickly disconnect and remove the worktable or control components from the maintenance area when maintenance is required. This quick-release design significantly reduces downtime for maintenance, lowers maintenance difficulty and costs, improves the overall uptime of the equipment, and ensures operational safety during maintenance.

[0024] In summary, by integrating multi-axis linkage machining, high-speed rotation, and convenient maintenance functions, this invention not only significantly improves the processing efficiency and accuracy of complex workpieces and reduces production costs and maintenance difficulties, but also enhances the safety and automation level of the equipment. It provides a high-performance solution for modern manufacturing and has significant economic and social benefits. Attached Figure Description

The integral forming or fixed connection of the horizontal base 611, the bent swing base 612, and the horizontal shaft 613 ensures the structural strength and rigidity of the boat-shaped base 61. The central groove 614 at the center of the horizontal base 611 provides integrated mounting space for the equipment platform 62 and the drive assembly 63. This compact structural design effectively reduces the overall volume, improves the stability of the tilting mechanism, and reduces rotational inertia, thereby supporting higher-speed tilting operations. The equipment platform 62 includes a main platform 621, a plug-in ring seat 622, and a connecting sealing plate 623. The main platform 621 has a central hole 620 for mounting the drive assembly 63 at its center. A first locking groove is formed on the side of the central hole 620. The plug-in ring seat 622 is fixedly installed at the center of the lower end face of the main platform 621 and is integrally formed with the main platform 621. An external bearing 624 that mates with the central groove 614 is sleeved and fixed on the outer surface of the plug-in ring seat 622. The drive assembly 63 includes a servo motor and a drive shaft. The servo motor is fixedly installed in the second locking groove corresponding to the first locking groove in the central groove 614. The drive shaft is fixedly connected to the output end of the servo motor, and a connecting strip 625 that mates with the first locking groove and the second locking groove is formed at the head of the drive shaft. The connecting sealing plate 623 is fixedly installed at the center of the main platform 621, and a connecting strip 625 that mates with the first locking groove and the second locking groove is fixedly installed at the lower end of the connecting sealing plate 623. The main platform 621, the plug-in ring seat 622, and the connecting sealing plate 623 of the equipment platform 62, together with the external bearing 624 on the outer side of the plug-in ring seat 622, ensure the smoothness and high precision of the rotation of the equipment platform 62 on the boat-shaped seat 61.The servo motor and drive shaft of the drive assembly 63, through the cooperation of the first locking groove, the second locking groove, and the connecting strip 625, achieve high torque, backlash-free power transmission and precise angular positioning. This precision connection and drive design ensures the stability and repeatability of the equipment table 62 during high-speed rotation and heavy-duty workpiece processing, thereby improving processing quality.

[0037] Reference Figure 10 and Figure 11The control component 7 includes a movable seat block 71 and a Y-shaped linkage frame 72. The movable seat block 71 is slidably mounted in the mating housing 114, and a threaded sleeve 711 that mates with the drive screw 116 is provided in the middle of the movable seat block 71. The lower end of the Y-shaped linkage frame 72 is rotatably mounted on the movable seat block 71. Two sets of guide shells 64 are fixedly mounted on both sides of the lower end face of the horizontal platform 611. An adjustable shaft group 65 that is slidably mounted in each guide shell 64 and rotatably connected to the head of the Y-shaped linkage frame 72 is also provided on the lower end face of the horizontal platform 611. A synchronous adjustment component 66 for adjusting the distance between the two sets of adjustable shaft groups 65 is also provided. This reveals the connection and adjustment mechanism between the control component 7 and the tilting worktable 6 through the movable seat block 71 and the Y-shaped linkage frame 72. The movable seat block 71, through its engagement with the drive screw 116 and the threaded sleeve 711, converts the rotational motion of the control motor 117 into precise linear displacement. The Y-shaped linkage 72 transmits this linear displacement to the adjustable shaft assembly 65 of the tilting worktable 6, thereby realizing the rotational adjustment of the tilting worktable 6. At the same time, the guide shell 64, the adjustable shaft assembly 65, and the synchronous adjustment component 66 provided on the lower end face of the horizontal base 611 not only ensure the accuracy of the tilting operation, but also provide a quick and reliable disconnection mechanism during maintenance, improving the maintenance efficiency and safety of the equipment. The guide housing 64 includes a reinforcing base plate 641 and a horizontal tube section 642. The reinforcing base plate 641 is vertically fixed to the lower end face of the horizontal base 611. The horizontal tube section 642 is fixedly installed at the lower end of the reinforcing base plate 641, and a guide groove 643 is provided on one side of the horizontal tube section 642. The adjustable shaft assembly 65 includes a plug-in shaft rod 651 and an outer connecting rod 652 installed in the guide groove 643. The plug-in shaft rod 651 is slidably installed in the horizontal tube section 642, and one end of the outer connecting rod 652 is fixed to the plug-in shaft rod 651. A synchronous adjustment component 6... The 6 includes a double-headed turntable 661, a linkage rod 662, and a second electric cylinder 663. The double-headed turntable 661 is rotatably mounted at the center of the lower end face of the horizontal base 611, and vertical shafts 664 are fixedly mounted on both sides of the lower end face of the double-headed turntable 661. One end of the linkage rod 662 is rotatably connected to the vertical shaft 664, and the other end of the linkage rod 662 is rotatably connected to the other end of the external connecting rod 652. The tail of the second electric cylinder 663 is rotatably mounted on the lower end face of the horizontal base 611, and the second electric cylinder 663 is used to drive the double-headed turntable 661 to rotate. The reinforcing base plate 641 and the horizontal tube 642 of the guide shell 64, together with the plug-in shaft rod 651 and the external connecting rod 652 of the adjustable shaft assembly 65, ensure the stability of the flip-type worktable 6 when connected to the control component 7 and the smooth sliding when disconnected. The coordinated action of the double-headed turntable 661, linkage rod 662, and second electric cylinder 663 of the synchronous adjustment component 66 enables the synchronous and precise adjustment of the two adjustable shaft groups 65, thereby achieving reliable disengagement and connection with the head of the Y-type linkage frame 72. This precise synchronous adjustment mechanism allows equipment maintenance to be carried out safely and efficiently with minimal time and manpower, greatly improving the availability of the equipment.

[0038] Working principle (mainly divided into two aspects: normal processing operation and equipment maintenance and repair): I. Normal Processing and Operation Phase Workpiece clamping and initial positioning: First, the workpiece to be processed is securely clamped on the equipment table 62 of the tilting worktable 6. The equipment table 62 is rotatably mounted in the central groove 614 of the boat-shaped seat 61 via the insertion ring seat 622 and the external bearing 624, and its angle is precisely controlled by the drive assembly 63 (internal servo motor and drive shaft). The boat-shaped seat 61 is rotatably mounted in the positioning axis seat 131 of the bed body 1 via the horizontal axis 613.

[0039] YXZ axis linkage machining: During machining, the control system (PLC and CNC controller), in coordination with drive components one, two, and three, controls the Y-axis movable seat 2, X-axis movable seat 3, and Z-axis movable seat 4 to slide with high precision on their respective guide rails. The Y-axis movable seat 2 slides on the auxiliary rail 132 at the upper end of the concave shell 13; the X-axis movable seat 3 slides on the first guide seat of the Y-axis movable seat 2 via the sliding part; and the Z-axis movable seat 4 slides on the second guide seat of the X-axis movable seat 3 via the moving part. The machining assembly 5 (including the machine base 51, machining motor 52, and tool holder 53) is fixedly installed at the lower end of the vertical frame of the Z-axis movable seat 4. Under the linkage control of the Y, X, and Z axes, the machining assembly 5 can perform precise three-dimensional machining operations on the workpiece clamped on the equipment table 62, such as milling and drilling.

[0040] High-speed flipping and multi-face machining: When machining another side of the workpiece is required, the control component 7 comes into play. The control motor 117 drives the drive screw 116 to rotate forward and backward. The drive screw 116 engages with the threaded sleeve 711 in the middle of the moving block 71, causing the moving block 71 to slide within the mating housing 114. The linear displacement of the moving block 71 is transmitted through the Y-type linkage frame 72 rotatably mounted at its upper end, transmitting force to the adjustable shaft assembly 65, which is rotatably connected to the head of the Y-type linkage frame 72. The adjustable shaft assembly 65 is fixed in the guide housing 64 at the lower end of the horizontal base 611 of the flipping worktable 6. Through the precise dragging of the control component 7, the flipping worktable 6 rotates around the horizontal axis 613 in the positioning shaft seat 131 at high speed and with high precision. Once the preset angle is reached, the flipping worktable 6 locks, the drive component 63 of the equipment table 62 further fine-tunes the workpiece angle, and then the XYZ axes are linked again to machine the new surface of the workpiece. This cycle repeats, achieving multi-face machining of the workpiece in a single clamping.

[0041] II. Equipment Maintenance and Repair Phase When the tilting worktable 6 or the control component 7 requires maintenance or repair, the present invention provides a convenient and efficient disengagement mechanism: Disconnecting the tilting mechanism from the control component: First, the control system activates the synchronization adjustment component 66. The tail of the second electric cylinder 663 is rotatably mounted on the lower end face of the horizontal base 611. It is driven to extend and retract, thereby driving the double-headed turntable 661 to rotate. When the double-headed turntable 661 rotates, the vertical shafts 664 fixedly mounted on both sides of its lower end face will synchronously push the plug-in shafts 651 of the two sets of adjustable shaft groups 65 outward through the linkage rod 662 (one end is rotatably connected to the vertical shaft 664, and the other end is rotatably connected to the other end of the external connecting rod 652). Driven by the external connecting rod 652, the plug-in shafts 651 slide outward in the horizontal tube 642, thereby disengaging the plug-in shafts 651 at both ends from the head of the Y-shaped linkage frame 72. At this point, the tilting mechanism of the tilting worktable 6 is completely separated from the control component 7 and is in a free state.

[0042] Remove the maintenance platform for maintenance: After the tilting mechanism is disconnected from the control component 7, the operator can activate the first electric cylinder 115 through the control system. The first electric cylinder 115 is installed in the housing 111 of the bottom shell 11 and is driven to extend and retract, pushing the maintenance platform 113 to one side along the sliding track, thereby moving the mating seat housing 114 (and the drive screw 116, control motor 117, and the moving seat block 71 and Y-type linkage frame 72 of the control component 7) fixedly installed on the upper surface of the maintenance platform 113 to one side of the housing 111.

[0043] Safety Inspection and Reset: The removal of the inspection platform 113 provides operators with a spacious and convenient maintenance area, allowing direct inspection, repair, or replacement of components on the control components 7 or the tilting mechanism beneath the tilting workbench 6, without the need to enter confined spaces, greatly improving the safety and efficiency of maintenance. After maintenance, the inspection platform 113 is reset using the first electric cylinder 115, and then the synchronous adjustment component 66 is driven by the second electric cylinder 663, causing the plug-in shafts 651 of the two adjustable shaft groups 65 to reconnect with the head of the Y-type linkage frame 72, thus restoring the normal operation of the equipment.

Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on the present invention are within the protection scope of the present invention.
