Description

Technical Field

[0001] The present invention relates to the technical field of plate unit welding, in particular to a plate unit U-rib internal welding multi-head integrated machine and a production change process. Background Art

[0002] Plate elements are core prefabricated components in modern steel structures, such as bridges and buildings. They consist of a welded composite panel and multiple ribs. The rib arrangement (e.g., U-ribs, T-ribs) directly impacts the fatigue performance and stability of the structure. For example, full-penetration welding of U-ribs in orthogonal special-shaped bridge plates can significantly improve fatigue resistance.

[0003] At present, the main working method of plate unit internal welding is to first hoist the assembled and positioned plate unit onto the assembly platform, and then the multiple internal welding arms of the gantry-type internal welding machine follow the gantry frame to the middle through hole of the fixed plate unit rib, insert it and perform internal welding; However, the ribs of different plate units have different sizes and quantities, and the redundant internal welding arms need to be removed to achieve the purpose of matching. However, the removal of the internal welding arms greatly increases the difficulty of production change and affects production efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a multi-head integrated machine for plate unit U-rib internal welding and a production change process. The following technical solutions are adopted: The plate unit U rib internal welding multi-head integrated machine includes an adjustable plate unit support unit and a multi-welding arm plate unit internal welding machine. The adjustable plate unit support unit includes a support frame device and a plate unit position adaptive adjustment positioning device. The top surface of the support frame device is used to support the plate unit to be welded. The plate unit position adaptive adjustment positioning device is used to fix the positions of both sides of the plate unit to be welded. The multi-welding arm plate unit internal welding machine includes a gantry, a gantry walking mechanism, multiple welders and multiple adjustable position welding arm devices. The gantry walking mechanism is installed at the bottom of the gantry and is located at the support The gantry travels on the track beam, and multiple welding machines are installed on the gantry. One end of multiple adjustable position welding arm devices is connected to the gantry, and the welding action is performed under the control of multiple welding machines respectively. The bottom is located on the multiple welding arm track beams and moves back and forth. The positions of the multiple adjustable position welding arm devices are adjusted by the welding arm position adjustment mechanism, so that the central axis positions of the multiple adjustable position welding arm devices coincide with the central axis of multiple U-ribs of the plate unit to be welded respectively. The gantry walking mechanism drives the gantry forward, and the multiple adjustable position welding arm devices respectively enter the multiple U-ribs of the plate unit to be welded to perform the plate unit internal welding action.

[0005] By adopting the above technical solution, the plate unit to be welded is first placed on the top surface of the support frame device. The support frame device provides the main load-bearing and basic positioning.

[0006] Next, the plate unit's adaptive positioning device activates, securing both sides of the plate unit to be welded. This adaptive adjustment allows for fine-tuning based on the unit's actual size and shape, ensuring a stable, non-moving position during welding, paving the way for subsequent precision welding.

[0007] The multi-arm plate unit welder is integrally mounted on a gantry. The gantry travels along a track (usually laid on the ground or a dedicated support structure) via a gantry travel mechanism at its base, enabling the entire equipment to move forward and backward to cover the entire welding area of ​​the plate unit to be welded.

[0008] The bottom of the equipment also rests on multiple support track beams, which provide additional stable support and ensure the stability of the gantry when traveling and working.

[0009] A plurality of welding machines are mounted on the gantry, each of which is connected to an adjustable position welding arm device, one end of which is fixed to the gantry.

[0010] The arm position adjustment mechanism allows for independent adjustment of the position of each adjustable arm. The goal is to precisely align the center axis of each arm with the center axis of the corresponding U-rib on the plate unit being welded. This is key to enabling rapid production changeovers for internal welding of plate units of varying sizes. Once all arms are correctly positioned, the gantry travel mechanism drives the gantry forward.

[0011] As the gantry moves forward, each adjustable position welding arm device, under the control of its own welding machine, enters the interior of the U rib along the center axis direction of its corresponding U rib.

[0012] The welder starts, and the plate unit internal welding carriage performs welding action inside the U rib, completing the plate unit internal welding. Because multiple welding arms and welders work simultaneously, multiple U ribs can be welded in parallel.

[0013] The design of the support frame device and the plate unit position adaptive adjustment positioning device enables it to adapt to plate units to be welded of different sizes and shapes, thereby improving the versatility of the equipment.

[0014] The adjustable position welding arm device allows adjustment according to the specific distribution and spacing of the U ribs to adapt to different plate unit designs.

[0015] The equipment has a high degree of automation, and the welding process is completed by the machine, which reduces the need for manual entry into the narrow and closed U-rib for welding, improves the workers' working environment, reduces labor intensity, and also reduces related safety risks.

[0016] Optionally, the tire frame device includes a plurality of fixed support beam assemblies and a tire frame plate. The bottoms of the plurality of fixed support beam assemblies can be detachably mounted on a prefabricated foundation, and the top forms a support surface. The bottom of the tire frame plate can be detachably mounted on the top surface of the plurality of fixed support beam assemblies. Fixed positioning process holes and dynamic positioning process holes are respectively opened on the support frame plate at positions corresponding to the plurality of fixed support beam assemblies.

[0017] Optionally, the supporting tire frame device also includes multiple plate unit lifting assemblies for auxiliary lifting, and the plate unit lifting assemblies include a lifting cylinder and a lifting column. The base of the lifting cylinder can be detachably installed on a prefabricated foundation, and the bottom of the lifting column can be detachably installed on the end of the piston rod of the lifting cylinder. When the piston rod of the lifting cylinder is extended or retracted, the lifting column is extended and retracted at the lifting auxiliary process hole opened on the supporting tire frame plate.

[0018] Optionally, the plate unit position adaptive adjustment positioning device includes a fixed end positioning component and a movable end positioning component, the fixed end positioning component includes a fixed end telescopic cylinder and a fixed hook plate, the cylinder body of the fixed end telescopic cylinder is detachably mounted on the fixed support beam component, one end of the fixed hook plate is detachably mounted on the end of the piston rod of the fixed end telescopic cylinder, and is located in the fixed positioning process hole, when the piston rod of the fixed end telescopic cylinder is retracted, the fixed hook plate fixes one side of the steel panel of the plate unit to be welded; the movable end positioning component includes a movable end linear guide rail, a movable end telescopic cylinder, a movable hook plate and a transverse moving hydraulic cylinder, the movable end linear guide rail and the transverse moving hydraulic cylinder The dynamic hydraulic cylinders are respectively installed on the fixed support beam assemblies, the cylinder body of the mobile end telescopic cylinder can be detachably installed on the slider of the mobile end linear guide rail, one end of the mobile hook plate can be detachably installed on the piston rod end of the mobile end telescopic cylinder, and is located in the dynamic positioning process hole, the piston rod of the transverse moving hydraulic cylinder is connected to the cylinder body of the mobile end telescopic cylinder, when the piston rod of the transverse moving hydraulic cylinder is extended or retracted, the mobile end telescopic cylinder is driven to move linearly on the track of the mobile end linear guide rail, and at the same time, the mobile hook plate is located in the dynamic positioning process hole and moves, and the position change between the mobile hook plate and the fixed hook plate matches the transverse dimensions of the plate units to be welded of different specifications.

[0019] By adopting the above technical solution, first, the plate unit to be welded is roughly placed on the support frame plate by external lifting equipment (such as a crane), so that its position roughly corresponds to the support surface formed by the fixed support beam assembly.

[0020] The operator then activates the panel unit lifting assembly. The piston rod of the lifting cylinder extends, driving the lifting column upward until it passes through the lifting auxiliary process hole opened in the support frame plate and supports the bottom of the panel unit to be welded.

[0021] As the lifting column continues to rise, it lifts the plate unit to be welded a small height from the support surface of the support frame plate, so that a small gap is created between the plate unit to be welded and the support frame plate. At this time, the external lifting equipment can be unhooked.

[0022] The piston rod of the fixed-end telescopic cylinder retracts, driving the fixed hook plate inward. The fixed hook plate is designed to enter the fixed positioning process hole in the support frame plate and ultimately hook onto the steel panel on one side of the plate unit to be welded. This provides a fixed and unchanging lateral positioning reference.

[0023] The lateral movement hydraulic cylinder is operated according to the specific lateral size (width) of the plate unit to be welded.

[0024] The piston rod of the lateral movement hydraulic cylinder extends or retracts, driving the telescopic cylinder at the mobile end and the cylinder body mounted thereon to move linearly and laterally along the linear guide rail at the mobile end.

[0025] The piston rod of the telescopic cylinder on the mobile end retracts, driving the movable hook plate inward, allowing it to enter the corresponding dynamic positioning hole on the support frame plate and hook onto the steel panel on the other side of the panel unit to be welded. By adjusting the position of the lateral hydraulic cylinder, the position of the movable hook plate relative to the fixed hook plate can be changed to accommodate panel units of varying widths. The design of the dynamic positioning hole allows for this position adjustment.

[0026] The piston rods of the fixed end telescopic cylinder and the movable end telescopic cylinder are respectively controlled to retract, and the movable hook plate and the fixed hook plate respectively position and press the steel panel of the plate unit to be welded; The plate units to be welded have been accurately positioned and fixed on the supporting jig device according to their own dimensions.

[0027] Optionally, the unit position adaptive adjustment and positioning device also includes a plate unit edge stripping mechanism, which includes a reverse moving telescopic cylinder and a reverse moving hook plate. The reverse moving telescopic cylinder is detachably mounted on a fixed support beam assembly, and one end of the reverse moving hook plate is mounted on the piston rod end of the reverse moving telescopic cylinder, and the other end is located in a fixed positioning process hole. When the piston rod of the reverse moving telescopic cylinder is in an initial position, the reverse moving hook plate is parallel to the fixed hook plate position. When the piston rod of the reverse moving telescopic cylinder is extended, the reverse moving hook plate separates one side of the plate unit to be welded from the fixed hook plate.

[0028] By adopting the above technical solution, when the plate unit is completed for welding and needs to be hoisted away from the supporting tire frame plate, the movable hook plate can be controlled to move away from the side of the plate unit, but the fixed hook plate is close to the other side of the plate unit. If it is not handled, it will affect the hoisting and lifting. At this time, the reverse moving telescopic cylinder is used to drive the reverse moving hook plate to separate the plate unit from the fixed hook plate, and then the reverse moving hook plate is reset, and the hoisting can begin.

[0029] Optionally, the adjustable position welding arm device includes a welding arm bottom support assembly, a welding arm, a welding trolley inside the plate unit and a welding arm position adjustment mechanism, wherein the bottom of the welding arm bottom support assembly is installed on the supporting rail beam, the bottom of the welding arm is located at the top of the welding arm bottom support assembly, one end of the welding arm is connected to the gantry, the welding trolley inside the plate unit is installed at the other end of the welding arm, and the welding arm position adjustment mechanism is used to adjust the position of the welding arm.

[0030] Optionally, the welding arm bottom support assembly includes a welding arm support frame, multiple frame support wheels, a welding arm transverse moving track beam, a welding arm transverse support column and a transverse support roller. The multiple frame support wheels are respectively installed at the bottom of the welding arm support frame. When the gantry moves, the multiple frame support wheels are located on the multiple welding arm track beams and move. The bottom of the welding arm transverse moving track beam can be detachably installed on the top of the welding arm support frame. The transverse support roller is installed at the bottom of the welding arm transverse support column. The bottom of the welding arm can be detachably installed on the top of the welding arm transverse support column. When the welding arm position adjustment mechanism drives the welding arm to move transversely, the transverse support roller is located on the welding arm transverse moving track beam and rolls to adjust the transverse position of the welding arm.

[0031] Optionally, the welding arm position adjustment mechanism includes a rack, multiple gear rings and multiple transverse drive motors, the bottom of the rack is installed on the welding arm support frame, the multiple gear rings are installed on the welding arm through bearing seats, and the gear rings are engaged with the rack, and the multiple transverse drive motors are installed on the welding arm, and respectively drive the multiple gear rings to move on the rack to realize lateral adjustment of the welding arm position.

[0032] By adopting this technical solution, the welding arm bottom support assembly is mounted on multiple support rail beams via multiple wheel support wheels. When the gantry travel mechanism drives the gantry forward and backward along the support rail beams, the entire welding arm bottom support assembly, along with the welding arm and panel unit welding carriage, moves longitudinally with it. This enables the welding arm assembly to cover the entire length of the panel unit.

[0033] The weld arm support frame provides the structural foundation for the entire bottom support assembly.

[0034] The top of the welding arm support frame is detachably mounted with a welding arm transverse movement track beam, which provides a guide rail for the transverse movement of the welding arm.

[0035] The bottom of the welding arm is detachably mounted on the top of the welding arm transverse support column. The bottom of the welding arm transverse support column is equipped with a transverse support roller.

[0036] When lateral position adjustment is required, the lateral support roller will enter the lateral movement track beam of the welding arm to provide support and guidance for the lateral movement of the welding arm.

[0037] The welding arm position adjusting mechanism is a core component, which includes a rack fixed on the welding arm support jig frame, a plurality of gear rings installed on the welding arm, and a plurality of transverse driving motors installed on the welding arm.

[0038] When the welding arm needs to be adjusted to a new transverse position, the transverse driving motor is started. The motor drives the gear ring connected thereto.

[0039] The gear ring is engaged with the fixed rack. The motor drives the gear ring to roll along the rack, thereby driving the entire welding arm and the welding arm transverse support column to move transversely on the welding arm transverse moving rail beam.

[0040] By controlling the rotation angle and direction of the plurality of transverse driving motors, the welding arm can be accurately adjusted to the target position, so that the central axis of the welding arm (and the plate unit inner welding trolley at the end thereof) is aligned with the central axis of a certain U rib on the plate unit to be welded.

[0041] After the adjustment is completed, the welding arm can move longitudinally with the gantry to perform welding of the U rib.

[0042] Optionally, a controller is further included, which controls the execution actions of the actuators of the adjustable plate unit support unit and the multi-welding arm plate unit inner welding machine respectively.

[0043] By adopting the above technical solution, PLC programmable controller or industrial control computer can be used to realize automatic control, or manual button type control can be used.

[0044] The plate unit U rib inner welding multi-head integrated machine production change process uses the plate unit U rib inner welding multi-head integrated machine to perform U rib inner welding on different specifications of plate units to be welded. The production change process for different specifications of plate units to be welded includes the following steps: Step 1, determine the steel panel width size of the plate unit to be welded, the size of the U rib, and the position data on the steel panel; Step 2, hoist the plate unit to be welded above the support jig plate, control the lifting columns of the plurality of plate unit lifting assemblies to rise, place the plate unit to be welded on the top of the plurality of lifting columns, remove the lifting device, retract the plurality of lifting columns, and place the plate unit to be welded on the top surface of the support jig plate; Step 3, control the piston rod of the transverse moving hydraulic cylinder to act, drive the moving hook plate to move transversely to contact one side of the plate unit to be welded, and further control the piston rod to act to make the other side of the plate unit to be welded contact the fixed hook plate to complete the position adjustment; Step 4, control the piston rods of the fixed end telescopic cylinder and the moving end telescopic cylinder to retract, respectively, and the moving hook plate and the fixed hook plate position and press the steel panel of the plate unit to be welded; Step 5, according to the fixed position of the to-be-welded plate unit U rib, the transverse driving motor of the plurality of adjustable position welding arm devices is controlled to act, so that the plate unit inner welding trolley is directed to the middle gap of the U rib, the welding arm position adjustment is completed, and the production change process is completed.

[0045] In summary, the present application includes at least one of the following beneficial technical effects: The present application can provide a plate unit U rib inner welding multi-head integrated machine and a production change process, and the design of the support jig device and the plate unit position self-adaptive adjustment positioning device can adapt to different sizes and shapes of to-be-welded plate units, and improve the versatility of the equipment.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings.

[0049] The embodiments of the present invention disclose a multi-head integrated machine for internal welding of U-ribs of plate units and a production change process.

[0050] Reference Figure 1 - Figure 9 , Example 1, a multi-head integrated machine for internal welding of plate units U ribs, including an adjustable plate unit support unit and a multi-welding arm plate unit internal welding machine, the adjustable plate unit support unit includes a support tire frame device 1 and a plate unit position adaptive adjustment positioning device, the top surface of the support tire frame device 1 is used to support the plate unit 100 to be welded, the plate unit position adaptive adjustment positioning device is used to fix the positions of both sides of the plate unit 100 to be welded, the multi-welding arm plate unit internal welding machine includes a gantry 21, a gantry walking mechanism 22, a plurality of welding machines and a plurality of adjustable position welding arm devices, the gantry walking mechanism 22 is installed at the bottom of the gantry 21, and is located on the upper side of the support track beam 101 Walking, multiple welding machines are installed on the gantry 21, one end of multiple adjustable position welding arm devices is connected to the gantry 21, and the welding action is performed respectively under the control of the multiple welding machines, the bottom is located on the multiple welding arm track beams 102 and moves back and forth, the positions of the multiple adjustable position welding arm devices are adjusted by the welding arm position adjustment mechanism, so that the central axis positions of the multiple adjustable position welding arm devices are coincident with the central axis of the multiple U ribs 1001 of the plate unit 100 to be welded, the gantry walking mechanism 22 drives the gantry 21 forward, and the multiple adjustable position welding arm devices respectively enter the multiple U ribs 1001 of the plate unit 100 to be welded to perform the plate unit internal welding action.

[0051] The plate unit 100 to be welded is first placed on the top surface of the support jig 1. The support jig 1 provides the main load-bearing and foundation positioning.

[0052] Next, the panel unit's adaptive positioning device activates, securing both sides of the panel unit 100 to be welded. This adaptive adjustment allows for fine-tuning based on the panel unit's actual size and shape, ensuring a stable, non-moving position during welding, paving the way for subsequent precision welding.

[0053] The multi-arm plate unit internal welding machine is integrally mounted on a gantry 21. The gantry 21 travels along a track 100 (usually laid on the ground or a dedicated support structure) via a gantry travel mechanism 22 at its bottom, enabling the entire equipment to move forward and backward to cover the entire welding area of ​​the plate unit 100 to be welded.

[0054] The bottom of the equipment is also located on multiple support track beams 101, which provide additional stable support to ensure the stability of the gantry 21 when traveling and working.

[0055] A plurality of welding machines are installed on the gantry 21, and each welding machine is connected to an adjustable position welding arm device. One end of these welding arm devices 24 is fixed on the gantry 21.

[0056] The welding arm position adjustment mechanism allows for independent adjustment of the position of each adjustable welding arm assembly. The goal is to precisely align the central axis of each welding arm 24 with the central axis of a corresponding U-rib 1001 on the panel unit 100 to be welded. This is key to enabling rapid production changeovers for internal welding of panel units of varying sizes. Once all welding arms 24 are correctly positioned, the gantry travel mechanism 22 drives the gantry 21 to begin forward movement.

[0057] As the gantry 21 moves forward, each position-adjustable welding arm device, under the control of its own welding machine, enters the interior of the U-rib 1001 along the central axis direction of its corresponding U-rib 1001 .

[0058] The welder starts, and the plate unit internal welding carriage performs welding action inside the U rib, completing the plate unit internal welding. Because multiple welding arms and welders work simultaneously, multiple U ribs can be welded in parallel.

[0059] By configuring multiple welders and adjustable position welding arms, the device can simultaneously weld multiple U-ribs 1001 on the plate unit 100. Compared with the traditional single-head welder welding method of welding one rib at a time, the welding time is greatly shortened and the production efficiency is significantly improved.

[0060] The design of the support frame device 1 and the plate unit position adaptive adjustment positioning device enables it to adapt to plate units 100 to be welded of different sizes and shapes, thereby improving the versatility of the equipment.

[0061] The position-adjustable welding arm device allows adjustment according to the specific distribution and spacing of the U-ribs 1001 to accommodate different plate unit designs.

[0062] The equipment has a high degree of automation, and the welding process is completed by the machine, which reduces the need for manual entry into the narrow and closed U-rib for welding, improves the workers' working environment, reduces labor intensity, and also reduces related safety risks.

[0063] In embodiment 2, the tire frame device 1 includes a plurality of fixed support beam assemblies 11 and a tire frame plate 12. The bottoms of the plurality of fixed support beam assemblies 11 are detachably mounted on a prefabricated foundation, and the top forms a supporting surface. The bottoms of the tire frame plate 12 are detachably mounted on the top surfaces of the plurality of fixed support beam assemblies 11. Fixed positioning process holes 121 and dynamic positioning process holes 122 are respectively opened on the tire frame plate 12 at positions corresponding to the plurality of fixed support beam assemblies 11.

[0064] In embodiment 3, the supporting tire frame device 1 also includes a plurality of plate unit lifting components for auxiliary lifting, and the plate unit lifting components include a lifting cylinder 131 and a lifting column 132. The base of the lifting cylinder 131 can be detachably mounted on a prefabricated foundation, and the bottom of the lifting column 132 can be detachably mounted on the end of the piston rod of the lifting cylinder 131. When the piston rod of the lifting cylinder 131 is extended or retracted, the lifting column 132 is extended and retracted at the lifting auxiliary process hole 123 opened on the supporting tire frame plate 12.

[0065] Example 4, the plate unit position adaptive adjustment positioning device includes a fixed end positioning component and a mobile end positioning component, the fixed end positioning component includes a fixed end telescopic cylinder 141 and a fixed hook plate 142, the cylinder body of the fixed end telescopic cylinder 141 is detachably mounted on the fixed support beam component 11, one end of the fixed hook plate 142 is detachably mounted on the piston rod end of the fixed end telescopic cylinder 141, and is located in the fixed positioning process hole 121, when the piston rod of the fixed end telescopic cylinder 141 is retracted, the fixed hook plate 142 fixes one side of the steel panel of the plate unit 100 to be welded; the mobile end positioning component includes a mobile end linear guide rail, a mobile end telescopic cylinder 151, a mobile hook plate 152 and a lateral moving hydraulic cylinder 153, the mobile end linear guide rail and the lateral moving hydraulic cylinder The cylinders 153 are respectively installed on the fixed support beam assembly 11, the cylinder body of the mobile end telescopic cylinder 151 can be detachably installed on the slider of the mobile end linear guide rail, and one end of the movable hook plate 152 can be detachably installed on the piston rod end of the mobile end telescopic cylinder 151 and is located in the dynamic positioning process hole 122. The piston rod of the transverse moving hydraulic cylinder 153 is connected to the cylinder body of the mobile end telescopic cylinder 151. When the piston rod of the transverse moving hydraulic cylinder 153 is extended or retracted, the mobile end telescopic cylinder 151 is driven to move linearly on the track of the mobile end linear guide rail, and at the same time, the movable hook plate 152 is located in the dynamic positioning process hole 122 and moves. The position change between the movable hook plate 152 and the fixed hook plate 142 matches the transverse dimensions of the plate units 100 to be welded of different specifications.

[0066] First, the plate unit 100 to be welded is roughly placed on the supporting frame plate 12 by external lifting equipment (such as a crane), so that its position roughly corresponds to the supporting surface formed by the fixed support beam assembly 11.

[0067] Then, the operator activates the panel unit lifting assembly. The piston rod of the lifting cylinder 131 extends, driving the lifting column 132 to move upward until the lifting column 132 passes through the lifting auxiliary process hole 123 opened on the support frame plate 12 and supports the bottom of the panel unit 100 to be welded.

[0068] As the lifting column 132 continues to rise, it lifts the plate unit 100 to be welded from the supporting surface of the support tire frame plate 12 by a slight height, so that a small gap is generated between the plate unit 100 to be welded and the support tire frame plate 12. At this time, the external lifting equipment can be unhooked.

[0069] The piston rod of the fixed-end telescopic cylinder 141 retracts, driving the fixed hook plate 142 inward. The fixed hook plate 142 is designed to enter the fixed positioning process hole 121 on the support frame plate 12 and ultimately hook onto the steel panel on one side of the panel unit 100 to be welded. This provides a fixed lateral positioning reference.

[0070] The lateral movement hydraulic cylinder 153 is operated according to the specific lateral size (width) of the panel unit 100 to be welded.

[0071] The piston rod of the transverse moving hydraulic cylinder 153 extends or retracts, driving the moving end telescopic cylinder 151 and the cylinder body mounted thereon to move linearly and transversely along the moving end linear guide rail.

[0072] The piston rod of the telescopic cylinder 151 retracts, driving the movable hook plate 152 inward, allowing it to enter the corresponding dynamic positioning process hole 122 on the support frame plate 12 and hook onto the steel panel on the other side of the panel unit 100 to be welded. By adjusting the position of the lateral hydraulic cylinder 153, the position of the movable hook plate 152 relative to the fixed hook plate 142 can be changed to accommodate panel units 100 of varying widths. The design of the dynamic positioning process hole 122 allows for this position adjustment.

[0073] The piston rods of the fixed end telescopic cylinder 141 and the movable end telescopic cylinder 151 are respectively controlled to retract, and the movable hook plate 152 and the fixed hook plate 142 respectively position and press the steel panel of the plate unit 100 to be welded; The plate unit 100 to be welded has been accurately positioned and fixed on the supporting jig device 1 according to its own size.

[0074] Example 5, the unit position adaptive adjustment and positioning device also includes a plate unit edge stripping mechanism, which includes a reverse moving telescopic cylinder and a reverse moving hook plate. The reverse moving telescopic cylinder is detachably mounted on the fixed support beam assembly 11, and one end of the reverse moving hook plate is mounted on the piston rod end of the reverse moving telescopic cylinder, and the other end is located in the fixed positioning process hole 121. When the piston rod of the reverse moving telescopic cylinder is in the initial position, the reverse moving hook plate is parallel to the fixed hook plate 142. When the piston rod of the reverse moving telescopic cylinder is extended, the reverse moving hook plate separates one side of the plate unit 100 to be welded from the fixed hook plate 142.
