Description
Technical Field
[0001] This invention relates to the field of welding tooling technology, specifically to a reconfigurable modular positioner platform and its rapid configuration method. Background Technology
[0002] The welding of assembly racks for automotive parts (such as battery trays, subframes, seat frames, etc.) is characterized by rapid product iteration, numerous batches, and significant differences in size and structure.

[0011] Preferably, a configuration method for a reconfigurable modular positioner platform includes the following steps: S1. The tailstock unit and the active unit are placed between the guide rails using a bracket and locking assembly. As they are placed, the contact plates in the power base are in contact with the contact plates, which are connected to an external power source. The inner guide plate powers the controller and other electrical components in the tailstock unit and the active unit, and simultaneously energizes the electromagnet, generating a repulsive force between it and the permanent magnet. This forces the pin tube to slide along the guide shaft, through the fixed housing, and into the positioning hole, thus fixing the position of the tailstock unit and the active unit. For larger components such as car chassis or battery racks, a number of intermediate frames can be selectively installed. These can also be positioned using a bracket and locking assembly. Before positioning is complete, a dual-axis motor can be started to drive the reduction gearbox, which in turn drives the rollers to rotate, adjusting the distribution position of the tailstock unit and the intermediate frames. While adjusting the position, a displacement sensor can monitor the displacement distance. S2. Start the reduction motor to drive the drive gear to rotate. Through the meshing between the gear teeth, drive the electric claw disk and the arc rod to move along the arc hole on one side of the guide frame, thereby adjusting the clamping angle of the electric claw disk and increasing the clamping range. The hydraulic cylinder extends to push the clamping assembly to rise. The pallet supports the component. The electric push rod retracts to drive the rotating frame to rotate. The baffle on one side of the pallet further clamps the component. With the tailstock unit and the drive unit, multiple components that need to be spliced and welded can be placed between the tailstock unit, the drive unit and the clamping assembly for welding. After the butt welding is completed, the clamping assembly can be released. The hydraulic cylinder retracts to drive the clamping assembly to move down. The servo motor drives the rotating disk to rotate, and the clamping unit drives the welded components to perform welding work in other positions. S3. After the tailstock unit, intermediate frame and active unit are installed, slide the data interface socket in the connecting rail to the corresponding position of the tailstock unit, intermediate frame and active unit. The data interface socket and the data interface in the interface component can be connected by a data cable, so that the data interface socket can be connected to the external control box or controller.
[0012] In summary, the beneficial effects of this invention are: This application utilizes standard modules such as a base insert plate, guide rails, tailstock unit, intermediate frame, and active unit. The number of intermediate frames can be flexibly increased or decreased, and the positions of each module on the guide rails adjusted, according to the size and structure of different workpieces. This allows for rapid reconfiguration of clamping and positioning solutions adapted to new products, fundamentally solving the problem of difficult production changeover with traditional dedicated positioners. Combined with a plug-and-play power base and sliding data interface, it enables rapid deployment, power supply, and communication of modules, significantly shortening equipment reconfiguration time. Positioning is reliable and repeatability is high. The clamping unit can adjust the angle of the jaw disc via a gear and rack mechanism. The clamping components have lifting, supporting, and clamping functions, adapting to the clamping requirements of different parts of the workpiece. The tailstock and active unit work together to provide rotational freedom, allowing the workpiece to be adjusted to the optimal welding posture, improving process adaptability.

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0016] Please see Figure 1-5This invention provides a technical solution: It includes a base insert plate 1, with a guide rail 2 connected to the top of the base insert plate 1. The lengths of the base insert plate 1 and the guide rail 2 can be increased as needed. The base insert plate 1 is fixedly installed on a workshop base. A tailstock unit 4, an intermediate frame 5, and an active unit 6 are slidably arranged above the guide rail 2. An interface component 7 and a controller 8 are connected to one side of each of the tailstock unit 4, intermediate frame 5, and active unit 6. A rotating disk 9 is connected to one side of each of the tailstock unit 4 and intermediate frame 5. A clamping unit 10 is connected to one side of each of the rotating disks 9. A card holder 11 is connected to the bottom of each of the tailstock unit 4, intermediate frame 5, and active unit 6. A locking component 12 is connected to the bottom of each card holder 11. A locking component 12 is connected to one side of each of the locking components 12. A displacement sensor 16 is provided. A power base 17 is connected to the bottom of the locking assembly 12. A power contact plate 18 is connected to the top of the base embedded plate 1. The power contact plate 18 is connected to an external power supply and also has power protection components such as a ground wire and an insulation layer. A clamping assembly 19 is connected to the top of the intermediate frame 5. A connecting rail 21 is connected to one side of the guide rail 2. A signal circuit board is provided inside the connecting rail for communication with the data interface socket 22 and for connection to an external control cabinet. The data interface socket 22 is slidably installed inside the connecting rail 21. The data interface socket 22 contains a wireless communication chip, which can be used for wired connection and wireless communication, and can transmit sensor information and control signals between the entire device. The tailstock unit 4 includes a support frame 41, with bearing seats 42 connected to both sides of the support frame 41. A connecting shaft 43 is rotatably connected between the bearing seats 42. An angle sensor 44 is connected to one side inside the support frame 41. One end of the connecting shaft 43 is connected to the rotating disk 9, and one end of the angle sensor 44 abuts against the rotating disk 9. When the component is connected to the clamping unit 10 on one side of the rotating disk 9, the component to be processed will rotate along with the component through the connecting shaft 43 when the active unit 6 drives the component to be processed to rotate. The active unit 6 includes a second support frame 61, with a fixed box 62 connected to the top of the second support frame 61. A reducer 63 is connected to one side inside the fixed box 62, and a servo motor 64 is connected to one side of the reducer 63. The output end of the reducer 63 is connected to another rotating disk 9. The reducer 63 is driven by the servo motor 64, and the reducer 63 drives the component to rotate actively through the rotating disk 9 and the clamping unit 10. The intermediate frame 5 includes a column 51, with a hydraulic cylinder 52 connected inside the column 51. The output end of the hydraulic cylinder 52 is connected to the clamping assembly 19.
[0017] Reference Figure 3As shown, a set of rollers 13 are connected to both sides of the locking assembly 12. A reduction gearbox 14 is connected to the side of each set of rollers 13 that is close to each other. A dual-axis motor 15 is connected between the reduction gearboxes 14. The dual-axis motor 15 drives the rollers 13 to rotate through the reduction gearboxes 14, thereby adjusting the position of the corresponding tailstock unit 4, intermediate frame 5 and active unit 6. The displacement position is monitored by the displacement sensor 16.
[0018] Reference Figure 2 As shown, the clamping assembly 19 includes a mounting base 191, with rotating frames 192 rotatably mounted on both sides of the mounting base 191. An electric actuator 193 is rotatably mounted on one side of each rotating frame 192, and a support plate 194 is rotatably mounted on the other side of the rotating frame 192. An anti-slip layer 195 is connected to the top of the support plate 194. The extension and retraction of the electric actuator 193 drives the rotating frame 192 to rotate, thereby causing the support plate 194 to shift. A baffle on one side of the support plate 194 clamps the component. The support plate 194 and the rotating frame 192 are connected by a spring shaft. The natural position of the support plate 194 is horizontal. With the cooperation of the hydraulic cylinder 52, the component can be supported and clamped.
[0019] Reference Figure 4 As shown, the locking assembly 12 includes a fixed housing 121. A fixed seat 122 is connected to the top of the inner side of the fixed housing 121. Connecting seats 123 are connected to both sides of the fixed seat 122. Guide shafts 124 are connected to the opposite sides of the connecting seats 123. A positioning pin assembly 125 is slidably mounted on one end of each guide shaft 124. A return spring 126 is connected between the positioning pin assembly 125 and the connecting seat 123. An electromagnet 127 is connected to the bottom of the inner wall of the fixed housing 121. A corresponding positioning pin is mounted on one side of the guide rail 2. The component 125 has multiple positioning holes 20. When the corresponding tailstock unit 4, intermediate frame 5 and active unit 6 move to the appropriate position, the electromagnet 127 is energized and a repulsive force is generated between it and the positioning pin assembly 125. This pushes the positioning pin assembly 125 to slide along the guide shaft 124 and insert it into the positioning hole 20, thereby completing the positioning. When adjustment or disassembly is required, the electromagnet 127 is de-energized, and the force between it and the positioning pin assembly 125 is released. The return spring 126 pulls the positioning pin assembly 125 to return to its original position, thus disconnecting it from the positioning hole 20.
[0020] Reference Figure 4 As shown, the positioning pin assembly 125 includes a permanent magnet 1251. A pin tube 1252 is connected to one side of the permanent magnet 1251, and protective pads 1253 are connected to both sides of the permanent magnet 1251. When the permanent magnet 1251 moves back and forth with the pin tube 1252, the protective pads 1253 on both sides will play a protective role to avoid collision damage.
[0021] Reference Figure 2As shown in the middle section, the power base 17 includes a compression airbag 171. An inner guide plate 173 is connected to the top of the compression airbag 171, and a power contact piece 172 is connected to the bottom of the compression airbag 171. The bottom surface of the power contact piece 172 is in contact with the power contact piece 18 and is electrically connected to the inner guide plate 173. When the tailstock unit 4, the intermediate frame 5, and the active unit 6 are located inside the guide rail 2, their own weight will compress the compression airbag 171, which can further ensure the contact between the power contact piece 172 and the power contact piece 18. The power components in the tailstock unit 4, the intermediate frame 5, and the active unit 6 are connected to the inner guide plate 173 through wires.
[0022] Reference Figure 5 As shown, the clamping unit 10 includes a fixed frame 101. Two guide frames 102 are connected to one side of the fixed frame 101. An arc-shaped rod 103 is slidably arranged between the guide frames 102. A support frame 104 is connected to one side of the arc-shaped rod 103. An electric gripper disc 105 is connected to the top of the support frame 104. A reduction motor 106 is connected to the bottom of the electric gripper disc 105. A drive gear 107 is connected to the output end of the reduction motor 106. Teeth 108 are provided on one side of the guide frame 102. One side of the drive gear 107 meshes with the teeth 108. The reduction motor 106 drives the drive gear 107 to rotate, and through the meshing with the teeth 108, it drives the electric gripper disc 105. The electric gripper disc 105 then slides along the arc-shaped hole on one side of the guide frame 102 with the arc-shaped rod 103 through the support frame 104, thereby adjusting the clamping angle of the electric gripper disc 105. When clamping from the side or other angles is required, adjustments can be made to ensure the applicable effect.
[0023] A configuration method for a reconfigurable modular positioner platform includes the following steps: S1. The tailstock unit 4 and the active unit 6 are positioned between the guide rails 2 via the bracket 11 and the locking assembly 12. Simultaneously, the contact plate 172 in the power base 17 abuts against the contact plate 18, which is connected to an external power source. The inner guide plate 173 powers the controller 8 and other electrical components in the tailstock unit 4 and the active unit 6, and simultaneously energizes the electromagnet 127, generating a repulsive force between it and the permanent magnet 1251. This repulses the pin tube 1252 along the guide shaft 124, penetrating the fixed housing 121. Insert into the positioning hole 20 to fix the position of the tail unit 4 and the active unit 6. For larger parts, such as car chassis or battery racks, a corresponding number of intermediate frames 5 can be selectively installed. Similarly, the card holder 11 and locking component 12 can be used for positioning and placement. Before the positioning is completed, the dual-axis motor 15 can be started to drive the reduction gearbox 14, which in turn drives the roller 13 to rotate, thereby adjusting the distribution position of the tail unit 4 and the intermediate frame 5. While adjusting the position, the displacement sensor 16 can monitor the displacement distance. S2. Start the reduction motor 106 to drive the drive gear 107 to rotate. Through the meshing with the teeth 108, drive the electric claw disk 105 and the arc rod 103 to move along the arc hole on one side of the guide frame 102, thereby adjusting the clamping angle of the electric claw disk 105 and increasing the clamping range. The hydraulic cylinder 52 extends and pushes the clamping assembly 19 to rise. The support plate 194 supports the parts. The electric push rod 193 retracts and drives the rotating frame 192 to rotate. The baffle on one side of the support plate 194 further clamps the parts. With the tailstock unit 4 and the drive unit 6, multiple parts that need to be spliced and welded can be placed between the tailstock unit 4 and the drive unit 6 and the clamping assembly 19 for welding. After the butt welding is completed, the clamping assembly 19 can be released. The hydraulic cylinder 52 retracts and drives the clamping assembly 19 to move down. The servo motor 64 drives the rotating disk 9 to rotate, and the clamping unit 10 drives the welded parts to perform welding work in other positions. S3. After the tailstock unit 4, intermediate frame 5 and active unit 6 are installed, slide the data interface socket 22 in the connecting rail 21. Corresponding to the positions of the tailstock unit 4, intermediate frame 5 and active unit 6, the data interface socket 22 and the data interface in the interface component 7 can be connected by a data cable, so that the data interface socket 22 can be connected to the external control box or controller.
