Description

Technical Field

[0001] The utility model relates to the technical field of curtain walls, in particular to a platform for assembling a hyperbolic curtain wall. Background Art

[0002] At present, with the development of the construction industry, the hyperbolic curved surface shape of high-end curtain walls has attracted more and more attention due to its unique appearance and functionality. However, the traditional curtain wall assembly method is mainly designed for flat units, and usually uses a simple flat working platform or a mobile flat vehicle-mounted rack for assembly. Although this method is suitable for the assembly of flat units, there are many limitations for the assembly of complex hyperbolic curtain wall units.

[0003] During the assembly process of hyperbolic curtain wall units, since the materials need to have specific curvatures and twist angles, it is difficult for traditional flat assembly platforms to simulate appropriate installation postures, resulting in difficult-to-guarantee assembly accuracy. In addition, although existing fixed profiling platforms can simulate the shape of hyperbolic curved surfaces to a certain extent, their fixedness leads to low efficiency in flow production, and it is easy to cause deformation during product handling and movement, increasing production costs and time costs.

[0004] Therefore, there is an urgent need for a platform for assembling a hyperbolic curtain wall to solve at least one of the above problems. Summary of the Utility Model

[0005] The utility model provides a platform for assembling a hyperbolic curtain wall, aiming to solve the problems that during the assembly process of hyperbolic curtain wall units, since the materials need to have specific curvatures and twist angles, it is difficult for traditional flat assembly platforms to simulate appropriate installation postures, resulting in difficult-to-guarantee assembly accuracy. In addition, although existing fixed profiling platforms can simulate the shape of hyperbolic curved surfaces to a certain extent, their fixedness leads to low efficiency in flow production, and it is easy to cause deformation during product handling and movement, increasing production costs and time costs.

[0006] In a first aspect, the utility model provides a platform for assembling a hyperbolic curtain wall, which is used for assembling a preset hyperbolic curtain wall unit, and includes:

[0007] A movable flow production vehicle, the bottom of which is provided with horizontally telescopic and adjustable support rods;

[0008] A plurality of independent lifting tools, which are slidably fixed along the longitudinal track of the flow production vehicle, and each lifting tool includes:

[0009] A tooling base fixed to the track, and a guide post is vertically arranged on the tooling base;

[0010] An upper support plate, the upper support plate is connected to a guide post through a screw drive mechanism, and the screw drive mechanism includes a handwheel penetrating through a tooling base; a profiling positioning assembly is arranged on the surface of the upper support plate;

[0011] Wherein, each of the independent lifting toolings corresponds to an independent height adjustment for forming a multi-point support array matching the bottom curved surface of the hyperbolic curtain wall unit.

[0012] In some embodiments, the telescopic range of the support rod is 1600mm - 2400mm.

[0013] Exemplarily, it further includes: a hydraulic drive device, connected to the support rod to adjust the telescopic amount of the support rod within the telescopic range.

[0014] In some embodiments, the number of the independent lifting toolings is 8, and the 8 independent lifting toolings are symmetrically distributed in two columns along the longitudinal axis of the flow operation vehicle.

[0015] In some embodiments, it further includes: a push plate, the push plate is connected to the bottom of the guide post, and the push plate is in contact with a thrust bearing connected to the handwheel in a transmission manner.

[0016] In some embodiments, the profiling positioning assembly includes a replaceable flexible contact pad, and the material of the flexible contact pad is a rubber composite material; the corresponding hardness range of the rubber composite material is 55H to 60H.

[0017] In some embodiments, it further includes: a controller, the controller stores height adjustment values of the independent lifting toolings; the controller is connected to each independent lifting tooling to adjust the height of the corresponding independent lifting tooling according to the height adjustment values.

[0018] Exemplarily, the controller further includes a touch display module and a parameter input module; for inputting and displaying the Z-axis coordinate adjustment amount of each independent lifting tooling.

[0019] In some embodiments, four universal moving wheels are arranged at the bottom of the flow operation vehicle, and each universal moving wheel is equipped with a foot-operated mechanical locking device.

[0020] In some embodiments, the handwheel is connected to the screw drive mechanism through a planetary gear reduction mechanism, and the reduction ratio of the planetary gear reduction mechanism is 1:20.

[0021] The present utility model relates to a profiling fixture platform for assembling hyperbolic curtain wall units, and its core lies in realizing the high-precision and high-efficiency frame assembly of hyperbolic curtain wall units through the collaborative design of a movable flow operation vehicle and multi-point independent lifting toolings.

[0022] The platform body is a flow operation vehicle with horizontally telescopic adjustable support rods at the bottom. The support rods can adapt to different ground conditions and enhance the stability of the operation vehicle. The bottom of the operation vehicle is equipped with mobile wheels (such as universal wheels or track wheels), enabling it to move flexibly in the production line, achieve rapid switching of workstations, and form a flow operation mode. A longitudinal track is set on the operation vehicle, and multiple independent lifting toolings are arranged along the track. Each tooling includes: the tooling base is slidably connected to the track through a locking mechanism, facilitating the adjustment of the tooling spacing to adapt to curtain wall units of different sizes; a guide post is vertically fixed on the tooling base, and the guide post is connected to the upper support plate through a screw drive mechanism. The handwheel penetrates the tooling base to drive the screw, realizing precise adjustment of the height of the upper support plate; positioning pins, card slots or vacuum adsorption devices are provided on the surface of the upper support plate to fix specific nodes of the curtain wall unit and ensure its assembly in a preset posture. The height of each independent lifting tooling can be adjusted individually. By driving the screw drive mechanism with the handwheel, the apexes of the upper support plates of all toolings form a discrete support point array that perfectly matches the bottom surface of the hyperbolic curtain wall unit. This array can dynamically simulate the local normal support force of the target hyperboloid, avoiding unexpected deformation of the unit due to gravity or external forces.

[0023] Through the discrete support of the bottom surface of the curtain wall unit by multiple independent lifting toolings, the problem that the traditional flat platform cannot fit the hyperboloid is solved. The height of each support point can be precisely adjusted according to design data (such as BIM models), ensuring that the unit is always in the theoretical posture during the assembly process and reducing local stress deformation caused by insufficient support.

[0024] The movable flow operation vehicle allows the same platform to rotate between different workstations. Combined with the rapid height reset function of the lifting tooling, it avoids the bottleneck of the traditional fixed profiling platform that requires repeated disassembly and assembly of the unit, significantly shortening the production beat. For example, after the tooling completes the assembly of one unit, it can be moved to the next workstation for sealant joint treatment, while another empty vehicle enters the assembly workstation to form a continuous production line. The unit completes the entire process from assembly to transfer on the movable platform without secondary hoisting and handling, avoiding the distortion and deformation caused by handling in the traditional process; the independent lifting tooling adopts a rigid guide post and screw drive, which has higher anti-eccentric load capacity compared with hydraulic or pneumatic lifting structures, ensuring the support stability of the unit during movement and reducing the rework rate. The slidable design of the tooling along the track, combined with independent height adjustment, can quickly reconstruct the support array to adapt to hyperbolic units with different curvatures and twist angles, especially suitable for small-batch customized production of special-shaped curtain walls, expanding the versatility of the platform. The mechanical structure driven by the handwheel to drive the screw does not require electric drive, reducing energy consumption and facilitating operators to finely adjust the height according to real-time measurement data (such as laser scanning feedback), realizing an integrated operation of "measurement - adjustment - locking" and reducing the input cost of automation equipment.

[0025] Meanwhile, in practical applications, the handwheel can be further replaced by a servo motor drive, and a numerical control system can be integrated to automatically control the lifting height of each tooling through a preset program to achieve fully automated frame assembly. In addition, the profiling and positioning component can be configured with pressure sensors to monitor the force on the support points in real time and dynamically adjust the height to balance the load distribution, further improving the accuracy.

[0026] In summary, through the innovative design of modularization, mobility, and discrete support, this technical solution has significant advantages in the accuracy, efficiency, and cost control of double-curved curtain wall unit assembly, and has strong industrial application value.

[0038] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] Currently, with the development of the construction industry, the hyperbolic surface shape of high - end curtain walls has attracted more and more attention due to its unique appearance and functionality. However, the traditional curtain wall assembly method is mainly designed for planar units, and usually a simple planar working platform or a mobile planar vehicle - mounted rack is used for assembly. Although this method is suitable for the assembly of planar units, there are many limitations for the assembly of complex hyperbolic curtain wall units.

[0040] During the assembly process of hyperbolic curtain wall units, since the materials need to have specific curvatures and twist angles, it is difficult for the traditional planar assembly platform to simulate a suitable installation attitude, resulting in difficult - to - guarantee assembly accuracy. In addition, although the existing fixed profiling platform can simulate the shape of the hyperbolic surface to a certain extent, its fixedness leads to low efficiency of flow production, and it is easy to cause deformation during the handling and movement of products, increasing the production cost and time cost.

[0041] Therefore, there is an urgent need for a platform for hyperbolic curtain wall assembly to solve at least one of the above problems.

[0042] To solve the above problems, please refer to Figure 1 and Figure 2, the present utility model provides a platform for assembling a hyperbolic curtain wall, which is used to assemble a preset hyperbolic curtain wall unit, and includes: a movable assembly line vehicle 10, the bottom of the assembly line vehicle is provided with a horizontally telescopic and adjustable support rod; a plurality of independent lifting tools 20, the independent lifting tools are slidably fixed along the longitudinal track of the assembly line vehicle, and each lifting tool includes: a tooling base 21 fixed to the track, a guide post 22 is vertically arranged on the tooling base; an upper support plate 23, the upper support plate is connected to the guide post 22 through a screw drive mechanism 24, and the screw drive mechanism 24 includes a handwheel 242 and a screw 241 penetrating through the tooling base; a profiling positioning assembly 25 is arranged on the surface of the upper support plate 23; wherein, each of the independent lifting tools corresponds to an independent height adjustment, and is used to form a multi-point support array matching the bottom curved surface of the hyperbolic curtain wall unit.

[0043] Among them, as Figure 2 shown, the tooling base 21 includes an upper base 211 and a lower base 212, and the upper and lower bases are connected by a fixing member 27, such as a screw.

[0044] Specifically, with the rapid development of the construction industry, the design of high-end curtain walls is gradually developing towards complexity and artistry. In particular, curtain walls with hyperbolic curved surface shapes are increasingly favored by architects and developers due to their unique appearance and functionality. However, traditional curtain wall assembly methods are mainly designed for flat units, and usually use simple flat working platforms or mobile flat vehicle racks for assembly. Although this method is suitable for the assembly of flat units, it has many limitations when facing complex hyperbolic curtain wall units.

[0045] The materials of hyperbolic curtain wall units need to have specific curvatures and twist angles. Traditional flat assembly platforms are difficult to simulate a suitable installation posture, resulting in the assembly accuracy being difficult to meet the design requirements. Although existing fixed profiling platforms can simulate the shape of hyperbolic curved surfaces to a certain extent, their fixedness leads to low assembly line efficiency and cannot meet the needs of large-scale production. The risk of deformation during product handling and movement: During handling and movement, fixed profiling platforms are likely to cause deformation of curtain wall units, increasing production costs and time costs.

[0046] To solve the above problems, the present utility model provides a platform for assembling a hyperbolic curtain wall, aiming to improve the assembly accuracy, enhance the assembly line efficiency, and reduce the risk of deformation during product handling and movement.

[0047] The platform of the present utility model is used to assemble a preset hyperbolic curtain wall unit. The core lies in the combination of a movable assembly line vehicle and a plurality of independent lifting tools to achieve high-precision and high-efficiency assembly of hyperbolic curtain wall units. The following is the specific technical content of this platform:

[0048] 1. Movable assembly line vehicle: The bottom of the assembly line vehicle is provided with horizontally telescopic and adjustable support rods to ensure the stability and adaptability of the platform in different working environments. The design of the assembly line vehicle enables it to move flexibly on the production line, meet the requirements of assembly line operations, and improve production efficiency.

[0049] 2. Multiple independent lifting toolings: The independent lifting toolings are slidably fixed along the longitudinal track of the assembly line vehicle. Each lifting tooling includes a tooling base, a guide post, an upper support plate, and a screw drive mechanism. The tooling base is fixed to the track, the guide post is vertically arranged on the tooling base, and the upper support plate is connected to the guide post through the screw drive mechanism. The screw drive mechanism includes a handwheel and a screw passing through the tooling base, and the height of the upper support plate is adjusted by rotating the handwheel. The surface of the upper support plate is provided with a profiling positioning component for accurately fixing the position of the hyperbolic curtain wall unit.

[0050] 3. Multi-point support array: Each independent lifting tooling corresponds to an independent height adjustment. Through the combination of multiple lifting toolings, a multi-point support array matching the bottom curved surface of the hyperbolic curtain wall unit is formed. This multi-point support method can accurately simulate the shape of the hyperbolic curved surface and ensure high precision during the assembly process.

[0051] The following will Figures 1 - 3 describe the specific implementation manners of the present utility model in detail:

[0052] The assembly line vehicle is made of high-strength steel. Horizontally telescopic support rods are arranged at the bottom, and the support rods are adjusted through a hydraulic system to ensure the stability of the platform under different ground conditions. The assembly line vehicle is equipped with drive wheels and a steering system, which can move flexibly on the production line and meet the requirements of assembly line operations. During use, the assembly line vehicle moves the platform to different workstations according to the rhythm of the production line to achieve efficient assembly line operations.

[0053] Each independent lifting tooling is fixed to the longitudinal track of the assembly line vehicle through the tooling base. A sliding connection is adopted between the tooling base and the track to facilitate the position adjustment of the tooling. The guide post is vertically arranged on the tooling base, and the upper support plate is connected to the guide post through the screw drive mechanism. The handwheel of the screw drive mechanism is located on one side of the tooling base, which is convenient for the operator to adjust the height. By rotating the handwheel, the screw drives the upper support plate to move up and down along the guide post to achieve precise adjustment of the height of the upper support plate. The surface of the upper support plate is provided with a profiling positioning component, and the profiling positioning component is designed according to the curved surface shape of the hyperbolic curtain wall unit to ensure the precise positioning of the curtain wall unit during the assembly process.

[0054] Multiple independent lifting tooling are arranged along the longitudinal track of the flow production vehicle, and the height of the upper support plate of each tooling is independently adjusted according to the curved surface shape of the hyperbolic curtain wall unit. Through the combination of multiple lifting tooling, a multi-point support array matching the bottom curved surface of the hyperbolic curtain wall unit is formed to ensure the stability of the curtain wall unit during the assembly process. In actual operation, the operator adjusts the height of each lifting tooling in sequence according to the design drawing, so that the profiling positioning component of the upper support plate is precisely matched with the curved surface of the curtain wall unit.

[0055] During the assembly process, the flow production vehicle moves the platform to the designated working station, and the operator adjusts the height of each lifting tooling in sequence according to the design drawing to ensure the precise assembly of the curtain wall unit. Through the movement of the flow production vehicle and the adjustment of the lifting tooling, the high-efficiency flow operation of the hyperbolic curtain wall unit is realized, greatly improving the production efficiency. During the handling and movement process, the mobility of the flow production vehicle and the independent adjustment function of the lifting tooling effectively reduce the deformation risk of the curtain wall unit and ensure the product quality.

[0056] The platform for assembling hyperbolic curtain walls of the present utility model has the following remarkable beneficial effects:

[0057] 1. Improve assembly accuracy: Through the combination of multiple independent lifting tooling, a multi-point support array matching the bottom curved surface of the hyperbolic curtain wall unit is formed, precisely simulating the shape of the hyperbolic curved surface to ensure high precision during the assembly process. The design of the profiling positioning component further improves the positioning accuracy of the curtain wall unit during the assembly process and reduces errors.

[0058] 2. Improve the efficiency of flow operation: The mobility of the flow production vehicle enables the platform to flexibly adapt to the rhythm of the production line and achieve efficient flow operation. The independent adjustment function of the independent lifting tooling enables each tooling to quickly adapt to different shapes of curtain wall units, reducing the adjustment time and improving the production efficiency.

[0059] 3. Reduce the deformation risk during the handling and movement of the product: The mobility of the flow production vehicle and the independent adjustment function of the lifting tooling effectively reduce the deformation risk of the curtain wall unit during the handling and movement process and ensure the product quality. The horizontal telescopic adjustment function of the support rod ensures the stability of the platform in different working environments and further reduces the deformation risk.

[0060] 4. Strong adaptability: The design of the platform enables it to adapt to hyperbolic curtain wall units of different shapes and sizes, with strong versatility and adaptability. The independent adjustment function of the independent lifting tooling enables the platform to quickly adapt to different production requirements and improves the production flexibility.

[0061] 5. Reduce production costs and time costs: By improving the assembly accuracy and the efficiency of flow production, the rework and adjustment time are reduced, and the production costs are lowered. The risk of deformation during the handling and movement of products is reduced, the rejection rate is decreased, and the production costs and time costs are further reduced.

[0062] In summary, the platform for assembling double-curved curtain walls of the present utility model realizes the high-precision and high-efficiency assembly of double-curved curtain wall units through the combination of a movable flow production vehicle and multiple independent lifting toolings. This platform not only improves the assembly accuracy and the efficiency of flow production, but also reduces the risk of deformation during the handling and movement of products, and has significant beneficial effects. Its design is flexible and has strong adaptability, and it can meet the assembly requirements of double-curved curtain wall units with different shapes and sizes, providing strong technical support for the production of high-end curtain walls in the construction industry.

[0063] In some embodiments, the telescopic range of the support rod is 1600 mm - 2400 mm.

[0064] By limiting the horizontal telescopic range of the support rod to 1600 - 2400 mm and adjusting it by mechanical or hydraulic means, the vehicle body span is ensured to adapt to the column grid spacing of standard workshops. A three-stage nested square tube (section 100 mm × 100 mm, wall thickness 8 mm) is adopted, with a telescopic stroke of 400 mm for each stage and a limit load of 15 tons. Each stage is equipped with a hydraulic pin (diameter 30 mm, material 40Cr), the pin hole spacing is 50 mm, and the positioning accuracy is ±1 mm. A pressure sensor (range 0 - 20 MPa) is arranged at the end of the telescopic rod, and an audible and visual alarm is triggered and automatically locked when overloaded by 10%.

[0065] Exemplarily, it further includes: a hydraulic drive device, connected to the support rod to adjust the telescopic amount of the support rod within the telescopic range.

[0066] The telescopic movement of the support rod is driven by a hydraulic device to achieve rapid and precise leveling. For example, a double-pump double-circuit system (main pump displacement 25 mL / r, emergency pump displacement 10 mL / r) is adopted, with a working pressure of 16 MPa, and an accumulator (volume 10 L) is equipped for pressure holding. PID closed-loop control is adopted, and the telescopic amount is fed back by a laser rangefinder (accuracy ±0.1 mm) to adjust the opening degree of the electromagnetic reversing valve. Inclination sensors (range ±5°, resolution 0.001°) are installed at the four corners of the vehicle body to automatically adjust the telescopic amount of the support rod so that the platform levelness ≤ 0.1°.

[0067] Furthermore, the time taken from deployment to leveling completion is ≤ 3 minutes (traditional mechanical adjustment takes 15 minutes). When the maximum unilateral support force difference is 20%, the platform tilt can still be controlled within 0.2°.

[0068] In some embodiments, the number of the independent lifting tools is eight, and the eight independent lifting tools are symmetrically distributed in two columns along the longitudinal axis of the flow operation vehicle.

[0069] As Figure 1 shown, eight independent lifting tools are symmetrically arranged in two columns along the longitudinal axis of the vehicle body, with four tools in each column. The column spacing is 1.5 m (adjustable range 1.2 - 1.8 m), and the spacing between tools in the same column is 2 m (adapting to the standard curtain wall unit grid size). The positions of the tools are determined by finite element topology optimization to make the bending moment distribution of the vehicle frame uniform (the maximum bending moment is reduced by 35%). The standard deviation of the force on the curtain wall unit is reduced from 15% of the traditional four-point support to 5% with eight-point support. After the support point density is increased, the fitting error of the hyperbolic surface is ≤ 0.5 mm / m (CMM detection data)

[0070] In some embodiments, it further includes: a push plate, which is connected to the bottom of the guide post and contacts with the thrust bearing that is in transmission connection with the handwheel.

[0071] As Figure 2 shown, the push plate 26 and the thrust bearing can reduce the operating torque of the handwheel.

[0072] The thrust bearing selected is a thrust ball bearing (dynamic load 28.5 kN, static load 51.2 kN), and the lubrication method is regular filling with lithium-based grease. The thickness of the push plate is 25 mm (material 40Cr, quenched and tempered to HRC28 - 32), and the contact surface with the bearing is plated with hard chromium (thickness 0.05 mm, hardness HV800). The driving torque of the handwheel is reduced from 8 N·m to 3 N·m, meeting the ISO 11244 ergonomics standard.

[0073] In some embodiments, the profiling positioning component includes a replaceable flexible contact pad, and the material of the flexible contact pad is a rubber composite material; the corresponding hardness range of the rubber composite material is 55H to 60H.

[0074] The profiling positioning component adopts a replaceable rubber composite flexible contact pad with a hardness of 55H - 60H (Shore A). For example, nitrile rubber (NBR) and polyurethane (PU) are blended (proportion 6:4), and carbon fiber (5 wt%) is added to enhance wear resistance, and the vulcanization temperature is 150 °C × 30 min. The thickness of the contact pad is 15 mm, and a magnet (neodymium iron boron N52) is embedded in the back to achieve rapid replacement. The surface is designed with fishbone patterns (depth 1 mm, spacing 3 mm) to increase the friction coefficient. Furthermore, when the contact pressure is 0.5 MPa, the scratch depth of the curtain wall aluminum plate is ≤ 5 μm (it reaches 20 μm when no gasket is used).

[0075] In some embodiments, it further includes: a controller that stores the height adjustment values of the independent lifting tooling; the controller is connected to each independent lifting tooling to adjust the height of the corresponding independent lifting tooling according to the height adjustment values.

[0076] The controller is used to store and automatically execute the height adjustment parameters of each tooling, realizing digital precise control. For example, the main control PLC, and the expansion module SM1223 is responsible for 16-channel analog input (tooling height feedback). The servo motor (rated torque 1.27 N·m) drives the screw, and the encoder resolution is 17 bits (131072 pulses per revolution).

[0077] By importing BIM model data (IFC format), the bottom surface coordinate points of the curtain wall unit are automatically parsed (density 100 points / m²). Based on the least squares method, the support point height is fitted to generate the tooling adjustment instruction (calculation time < 1 s). At the same time, the adjustment of the height by the controller can refer to the conventional height adjustment methods in the art.

[0078] Exemplarily, the controller further includes a touch display module and a parameter input module; it is used to input and display the Z-axis coordinate adjustment amount of each independent lifting tooling.

[0079] By integrating the touch screen and the parameter input module in the controller, it supports visual operation. For example, a 10.1-inch industrial touch screen is adopted (resolution 1280×800, protection level IP67), capacitive multi-touch. The physical button area is equipped with a rotary encoder (accuracy 0.1°) and an emergency stop button (compliant with IEC 60947-5-5 standard). Through the touch display module, the matching degree between the tooling height and the curtain wall surface is displayed in 3D in real time (the color gradient represents the deviation, red > 0.3 mm, green ≤ 0.1 mm). It supports gesture zooming and viewing angle switching, and loads STEP format model files (maximum support 500 MB).

[0080] In some embodiments, four universal moving wheels are provided at the bottom of the flow operation vehicle, and each universal moving wheel is equipped with a foot-operated mechanical locking device.

[0081] By installing four groups of universal wheels at the bottom of the vehicle body, a foot-operated mechanical locking device is equipped. The material of the universal wheel body is polyurethane (wheel diameter 250 mm, width 80 mm), the single-wheel load-bearing capacity is 2 tons, and the temperature resistance is -30°C to 100°C. The steering mechanism adopts a plain bearing (type 51144) + helical gear transmission (module 3, transmission ratio 1:1.5). The foot-operated connecting rod drives the cam mechanism to force the brake pad (material phenolic resin) to contact the wheel surface, and the braking torque ≥ 200 N·m. Through mechanical locking + hydraulic brake, accidental sliding is prevented. Furthermore, the minimum turning radius of the vehicle body is 1.2 m, and it can freely turn in a narrow passage (width ≥ 2 m). The displacement of the vehicle body after locking < 0.05 mm / hour (detected by a laser interferometer).

[0082] In some embodiments, the hand wheel is connected to the screw transmission mechanism through a planetary gear reduction mechanism, and the reduction ratio of the planetary gear reduction mechanism is 1:20.

[0083] The handwheel drives the screw through the planetary gear reduction mechanism (reduction ratio 1:20) to improve the adjustment accuracy. The reducer adopts a planetary gearbox (three-stage transmission), and the gear material is 20CrMnTi carburized and quenched (tooth surface hardness HRC58-62). The input shaft is directly connected to the handwheel, and the output shaft is connected to the screw through a cross slider coupling (made of aluminum alloy 7075). A self-locking worm (lead angle γ=3.5°, friction angle ρ=6°) is integrated at the output end of the reducer to ensure reverse self-locking.

[0084] Each turn of the handwheel corresponds to a screw lift of 0.2mm (lead 4mm / reduction ratio 20), and the fine adjustment capability is improved. When the static load is 5 tons, the screw slides down less than 0.01mm / hour (GB / T 10095.1-2008 gear accuracy level 4).

[0085] like Figures 1 - 3 As shown, during the use of the platform provided by the present application, the YZ data of 8 points are pre-adjusted according to the drawing data. These 8 positions are the bottom point postures of the profiling hyperbolic unit, so that the product can be accurately supported to prevent deformation. The corresponding materials are placed on the platform, and after being installed and pre-tightened, they are moved forward, backward, left and right to the same positioning points on the drawing and the tooling points, and then the corresponding screws are tightened. Finally, the glass is installed and a crane is used to drop the glass onto the frame. Then, the bottom posture of the unit is simulated at multiple points to facilitate the installation of the assembly frame; at the same time, the bottom of the platform has multiple points to support the installation of the glass, and the force is evenly distributed; the tooling platform is used until it is shipped out of the warehouse, and compared with a fixed platform, the risk of unit movement and deformation is avoided.

[0086] In some embodiments, an electric fine-tuning device is added between the handwheel and the planetary gear reducer, including a piezoelectric ceramic driver (stroke ±50μm, resolution 10nm) and a strain gauge feedback system to achieve nanometer-level precision compensation after coarse adjustment of the handwheel.

[0087] The piezoelectric ceramic driver (maximum thrust 800N) is embedded in the input shaft of the reduction gearbox and coupled with the handwheel shaft through an elastic coupling, with an axial preload of 200N. The strain gauge is attached to the bottom of the upper support plate to form a Wheatstone bridge to detect micro-strain signals (sensitivity coefficient 2.0±1%). The handwheel drives the support plate to the target height within the range of ±0.1mm. The piezoelectric ceramic compensates for the residual error with the PID algorithm (sampling frequency 1kHz) based on the feedback of the strain gauge, and the final positioning accuracy reaches ±0.005mm. When the compensation amount exceeds 40μm, an alarm is triggered and the system switches to manual mode.

[0088] In some embodiments, by adding a lateral stabilizer bar and a gravity center monitoring module, the offset of the vehicle body's center of gravity is calculated in real time and the load distribution of the support rods is dynamically adjusted. Lateral stabilizer bar: Two Φ50mm hollow steel pipes (wall thickness 6mm) are cross-welded at the bottom of the vehicle body, and a hydraulic damper (adjustable damping coefficient range 100 - 500N·s / m) is set at the node; Gravity sensors: Four groups of high-precision weighing modules (model HBM PW15C3, range 0 - 25 tons, accuracy ±0.02%FS) are embedded at the roots of the support rods to monitor the loads at each support point in real time. Calculate the center of gravity coordinates (X, Y) based on the weighing data and compare with the safety envelope (90% of the vehicle body's projected area); If the center of gravity offset exceeds the limit (>5% of the vehicle body length), control the corresponding support rod hydraulic cylinder to increase pressure (step value 1MPa / time) until the center of gravity returns to the safe zone.

[0089] In some embodiments, by adding a temperature-deformation coupling compensation system, including a distributed temperature sensor and a database of thermal expansion coefficients, the deviation of the tooling height caused by temperature changes is automatically corrected.

[0090] Temperature sensor: 24 PT100 platinum resistors (accuracy ±0.1℃) are embedded in the tooling base, guide posts and upper support plate to monitor the temperature gradient at key parts; A laser rangefinder (resolution 0.001mm) measures the actual elongation of the guide posts in real time. Establish a material thermal expansion model. In the ambient temperature range of -20℃ to 50℃, the tooling height drift is reduced from ±0.2mm to ±0.02mm; Eliminate the misalignment of the curtain wall units caused by day-night temperature differences, and increase the installation qualification rate from 85% to 99.5%.

[0091] In some embodiments, by integrating an air-blowing-scraper composite cleaning mechanism, including a liftable scraper, a negative pressure dust collection tank and an air curtain generator, the debris on the guide rail surface is removed in real time.

[0092] The scraper assembly uses a polyurethane scraper (hardness 90A) installed at the front end of the slider and is driven by a cylinder to contact the track (adjustable pressure range 10 - 50N); The air curtain is arranged with slit nozzles (slit width 0.3mm) on both sides of the track, and compressed air (pressure 0.6MPa) is sprayed to form a barrier to prevent dust from adhering.

[0093] When the tooling moves, the scraper descends to scrape off foreign objects on the track surface, and the debris falls into the negative pressure dust collection tank (suction 200Pa); The air curtain continues to blow air for 3 seconds after the tooling passes to ensure that the cleanliness of the track reaches the ISO 8573-1 Class 2 standard.

[0094] In some embodiments, a dual-power redundancy mechanism is added, including a main servo motor and a backup stepper motor, and seamless switching is achieved through an electromagnetic clutch in case of a failure.

[0095] The main drive is a servo motor (rated power 3kW) directly connected to a planetary gearbox; the backup drive is a stepper motor (holding torque 12N·m) connected to the input shaft of the gearbox through a synchronous belt (transmission ratio 1:1); electromagnetic clutch: disconnects the backup drive under normal conditions and closes within 0.1 seconds in case of a fault. Real-time monitoring of the servo motor current (Hall sensor), encoder signal; if stalling (current > 20A), loss of steps (pulse error > 5%) or communication interruption is detected, immediately switch to the backup drive.

[0096] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
