[0004] At present, the welding positioning device for door panel columns and the above-mentioned case use the cooperation of a robotic arm for welding processing. However, in specific use, there are multiple solder joint positions, and the door panel columns need to be flexibly repositioned. At the same time, during the welding process, stable support ability needs to be maintained. The door panel columns need more automated splicing processing so that welding can be carried out in the splicing and limiting state, increasing the firmness of the later connection. Therefore, the existing welding positioning device for door panel columns needs to be improved. Summary of the Invention

[0005] In view of the problems in the prior art, the present invention provides a welding positioning device for door panel columns.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a welding positioning device for door panel columns, including a guiding and outputting structure, a cooperating and repositioning structure, and an assembling and combining structure. The cooperating and repositioning structure is limited and fixedly connected to the upper end of the assembling and combining structure, and the guiding and outputting structure is limitedly connected to the cooperating and repositioning structure;

[0007] The guiding and outputting structure is used for the transmission processing of assembled objects, and the guiding and outputting structure adopts automatic limiting clamping to be able to transmit the objects to a specified position;

[0008] The cooperating and repositioning structure is used for the limitation of the door panel column welded body, and at the same time can drive the door panel column welded body to perform flipping adjustment, so as to perform flipping adjustment of the front and back sides of the door panel column welded body for double-sided welding processing;

[0009] The assembly combination structure is used for the limit splicing of columns and door panels, and at the same time, automatic material guiding control is carried out. Under the processing of the welding robot, automatic welding processing is carried out.

[0010] Specifically, the guiding and output structure includes a displacement plate, a combined frame, an inner frame and a lifting limit component. A lead screw is rotatably connected to the combined frame, and the lead screw is driven by a motor. The lead screw is threadedly connected to the displacement plate to change the position of the displacement plate on the combined frame and the inner frame. A guiding belt is provided with a limit at the lower end of the combined frame. A lifting limit component is fixedly connected to the lower end of the displacement plate, and the limit lifting of the door panel column welding body is carried out through the lifting limit component.

[0011] The lifting limit component includes a movable adjustment frame. The lower end of the movable adjustment frame is telescopically connected to a limiting plate through a hydraulic lifting rod. A hydraulic control seat is installed on the limiting plate, and the hydraulic control seat controls the telescopic adjustment of the load-bearing guide rod. A protective plate is fixedly connected to the side end of the limiting plate, and a motor is installed on the protective plate. The motor can drive the turntable and the gear teeth to rotate through driving. Both gear teeth are arranged on the turntable, and the limiting clamping of the door panel column welding body is carried out through the rotation of the gear teeth.

[0012] Specifically, the matching and transposition structure includes a top frame. A cylinder is fixedly installed on the top frame, and the cylinder controls the telescopic adjustment of the docking seat. A stable connecting frame is fixedly connected to the side of the docking seat away from the cylinder, and a stepping motor is fixedly installed on the side end of the stable connecting frame. Through rotation, the stepping motor can drive the rotation adjustment shaft to rotate, so that the rotation adjustment shaft drives the telescopic limit clamping seat and the limiting outer frame to rotate synchronously. Through the structural setting of the guiding and output structure, the door panel column welding body can be lifted and transported. When it is necessary to transfer and guide the processed door panel column welding body, at this time, the hydraulic lifting rod controls the lowering of the limiting plate, and at the same time, the hydraulic control seat controls the extension of the load-bearing guide rod to carry out the limiting support of the door panel column welding body. At the same time, the motor can drive the turntable and the gear teeth to rotate. At this time, the gear teeth can clamp the door panel column welding body, so as to carry out multi-point support of the door panel column welding body. Then, the lead screw is driven by the motor to change the position of the displacement plate. The displacement plate can change the position of the limiting plate through the movable adjustment frame, and at the same time, the door panel column welding body reaches the guiding belt. Through the driving control of the guiding belt, the transfer and disposal work of the door panel column welding body is carried out. The cylinder in the matching and transposition structure can control the telescopic adjustment of the stepping motor, so that the rotation adjustment shaft drives the limiting outer frame to move, and the door panel column welding body is limited. At the same time, the telescopic limit clamping seat is electrically controlled to reinforce and limit the door panel column welding body again. Then, the stepping motor can control the rotation of the rotation adjustment shaft, so that the door panel column welding body rotates accordingly, and the door panel column welding body is turned over to better carry out the welding treatment work at the bottom position, so as to carry out flexible transposition treatment of the door panel column and process multiple welding point positions.

[0013] The telescopic limit clamping seat on the restricted external frame is controlled to expand and contract electrically, thereby limiting the welded body of the door panel column. Through the drive of the stepping motor, the rotation control of the welded body of the door panel column is realized. At the same time, the rotation adjustment shaft and the telescopic limit clamping seat are adjusted to expand and contract through the control of the cylinder.

[0014] Specifically, the assembly combination structure includes assembly components, and welding robots are installed at the four corner positions of the assembly components for welding work;

[0015] The assembly components include a column loading control mechanism, an assembly adjustment mechanism, and a door panel loading control mechanism. The column loading control mechanism is used for the transmission of the door panel, and the door panel loading control mechanism is used for the transmission of the column. Moreover, the column and the door panel can be assembled and combined. There are two column loading control mechanisms and two door panel loading control mechanisms, and they are symmetrically distributed. The assembly adjustment mechanism is arranged at the center of the column loading control mechanism and the door panel loading control mechanism. Through the assembly adjustment mechanism, the column and the door panel are assembled, and at the same time, the height positions of the column and the door panel can be changed.

[0016] Specifically, the column loading control mechanism includes a bottom frame, a displacement folding frame, and a hydraulic telescopic regulator. The hydraulic telescopic regulator is fixedly installed on the bottom frame, and the hydraulic telescopic regulator controls the expansion and contraction of the displacement folding frame. The displacement folding frame is arranged in a right-angle bending structure. A pushing main rod is fixedly connected to the side end of the displacement folding frame, and a storage seat is fixedly connected to the top of the bottom frame;

[0017] The hydraulic telescopic regulator controls the position of the pushing main rod through the displacement folding frame, so that the pushing main rod can feed the door panel in the storage seat.

[0018] Specifically, the assembly and adjustment mechanism includes a supporting main board. A hydraulic lifting base is provided at the bottom of the supporting main board. The hydraulic lifting base changes the position of the displacement adjustment plate through telescoping. A positioning main seat is installed in the middle of the displacement adjustment plate. The positioning main seat controls the telescopic adjustment of the contact push block through a hydraulic adjustment rod. An extension plate is fixedly provided at the front end of the positioning main seat. The supporting main board is fixed to the chassis to support and connect. An auxiliary hydraulic adjustment plate seat is also telescopically controlled on the displacement adjustment plate. Through the telescopic adjustment of the auxiliary hydraulic adjustment plate seat, the door panel column welding body can be pushed for secondary height adjustment. Through the structural setting of the assembly combination structure, the splicing of columns and door panels is convenient. The door panel feeding control mechanism can perform automatic guiding and discharging of columns. At the same time, the column feeding control mechanism performs guiding and discharging of door panels. Through the setting of the assembly and adjustment mechanism, the columns and door panels can be spliced and combined. The hydraulic telescopic regulator controls the telescopic adjustment of the displacement folding frame, thereby changing the position of the pushing main rod, so that the door panels on the storage seat are transmitted and pushed. The columns and door panels are combined on the displacement adjustment plate. The positioning main seat can change the position of the contact push block through the hydraulic adjustment rod. At this time, the door panel is positioned under the action of the pushing main rod and the contact push block. The column is limited at the front end of the extension plate through pushing control. Thus, under the control action, the columns and door panels are combined. The hydraulic lifting base can adjust the height of the displacement adjustment plate. At the same time, the auxiliary hydraulic adjustment plate seat can perform telescopic control for fine adjustment of the secondary door panel column welding body.

[0019] Specifically, the door panel feeding control mechanism includes a feeding control part and a pushing and guiding part. The feeding control part is used for the feeding control of columns. The pushing and guiding part is used for pushing the columns so that the columns reach the assembly and adjustment mechanism.

[0020] The feeding control part includes a guiding channel. A protective partition frame is fixedly connected to the side end of the guiding channel. The front end of the guiding channel communicates with the storage frame. A driving guide shaft is rotatably connected to the protective partition frame near one side of the guiding channel. A limiting tooth sleeve is fixedly connected to the driving guide shaft. The driving guide shaft is driven by a motor. A pushing limiting guide plate is telescopically connected to the side end of the protective partition frame. A cooperative guide rod is fixedly connected to the side end of the pushing limiting guide plate. A cooperative guide plate is fixedly connected to the lower end of the cooperative guide rod. A limiting pushing guide plate is fixedly connected to one side of the upper part of the cooperative guide plate. A tooth plate is fixedly connected to one side of the lower part of the cooperative guide plate. A lifting control feeding guide rod is installed at the side end of the storage frame. The lifting control feeding guide rod can change the position of the hydraulic control partition frame. The bottom of the storage frame is blocked by the hydraulic control partition frame, so as to perform Guo Ze transmission processing on the columns. The lower end of the guiding channel is supported by a bearing combination seat.

[0021] Specifically, the propulsion guiding part includes a stabilizing block base, on which an electric-controlled propulsion telescopic control rod is installed. The front end of the electric-controlled propulsion telescopic control rod is limited by a front plate, and the front plate slides on the platform frame. The side end of the platform frame is fixedly connected with a limiting and matching groove plate, and the side end of the limiting and matching groove plate is fixedly connected with a protective frame. The bottom of the platform frame is fixedly connected with a bottom support combined frame. A control motor is installed inside the center of the bottom support combined frame, and a driving sprocket is drivenly connected to the control motor. The driving sprocket is meshed with a toothed plate. A spring shaft seat is slidably connected to the limiting and matching groove plate. A moving plate is hinged to the side end of the spring shaft seat. The rear end of the moving plate is elastically connected with a return spring, and the bottom of the return spring is limitedly connected with the limiting and matching groove plate through a seat body. Through the structural setting of the door panel loading control mechanism, the guiding and transmission of the upright post can be carried out. The upright post can reach the storage frame through the guiding channel and be stored on the storage frame. The electric-controlled propulsion telescopic control rod can push the upright post through the front plate and drive the moving plate to move accordingly. When the upright post reaches the frontmost position, the limiting and matching groove plate no longer limits the bottom of the moving plate at this time. The moving plate can rotate through the spring shaft seat at this time. The upright post continues to be pushed and reaches the assembling and adjusting mechanism. Then, the limiting and matching groove plate is reset under the control of the return spring. Before the upright post is transmitted, the control motor can control the driving sprocket to rotate at this time, so that the two limiting and pushing guide plates move symmetrically horizontally to center-align the upright post, which better helps the subsequent splicing and processing purpose.

[0022] Specifically, a horizontal groove is formed in the limiting and matching groove plate, and the spring shaft seat slides in the horizontal groove of the limiting and matching groove plate. The upright post is pushed by the front plate, and the front end of the upright post is connected to the moving plate. When the moving plate reaches the front position of the limiting and matching groove plate, the moving plate can be flipped and adjusted through the spring shaft seat at this time, and the upright post is slidably adjusted through the top of the flipped moving plate.

[0023] Specifically, when the toothed plate moves and adjusts, it drives the cooperative guide plate, the limiting and pushing guide plate, the cooperative guide rod, and the pushing and limiting guide plate to move together. The pushing and limiting guide plate can limit the upright post on the guiding channel. When the limiting and pushing guide plate moves, it can center-align the upright post transmitted at the bottom.

[0024] The beneficial effects of the present invention:

[0025] 1. Through the structural design of the guiding output structure, the present invention can lift and transport the welded body of the door panel column. When it is necessary to transfer and guide the processed welded body of the door panel column, the hydraulic lifting rod controls the lowering of the limiting plate, and at the same time, the hydraulic control seat controls the extension of the bearing guide rod to provide limit support for the welded body of the door panel column. Meanwhile, the motor can drive the turntable and the cogs to rotate. At this time, the cogs can hold the welded body of the door panel column, thus providing multi-point support for the welded body of the door panel column. Then, the lead screw is driven by the motor to change the position of the displacement plate. The displacement plate can change the position of the limiting plate through the movable adjustment frame, and at the same time, the welded body of the door panel column reaches the guiding belt. Through the driving control of the guiding belt, the welded body of the door panel column is transported and processed. By cooperating with the cylinder in the transposition structure, the stepping motor can be controlled to expand and contract, so that the rotating adjustment shaft drives the limiting outer frame to move, limiting the welded body of the door panel column. At the same time, the telescopic limit clamping seat is electrically controlled to reinforce and limit the welded body of the door panel column again. Then, the stepping motor can control the rotation of the rotating adjustment shaft, so that the welded body of the door panel column rotates accordingly, enabling the welded body of the door panel column to be turned over for better welding treatment at the bottom position, thus flexibly transposing the door panel column and processing multiple welding points.

[0026] 2. Through the structural design of the assembly and combination structure, the present invention facilitates the splicing of the column and the door panel. The door panel feeding control mechanism can automatically guide and arrange the column, and at the same time, the column feeding control mechanism guides and arranges the door panel. Through the setting of the assembly and adjustment mechanism, the column and the door panel can be spliced and combined. The hydraulic telescopic regulator controls the expansion and contraction of the displacement folding frame, thereby changing the position of the pushing main rod, enabling the door panel on the storage seat to be transported and pushed. The column and the door panel are combined on the displacement adjustment plate. The positioning main seat can change the position of the contact push block through the hydraulic adjustment rod. At this time, the door panel is positioned under the action of the pushing main rod and the contact push block. The column is limited at the front end of the extension plate through the pushing control, so that the column and the door panel are combined under the control action. Moreover, the hydraulic lifting base can adjust the height of the displacement adjustment plate, and at the same time, the auxiliary hydraulic adjustment plate seat can perform telescopic control for fine adjustment of the secondary welded body of the door panel column.

[0027] III. Through the structural design of the door panel feeding control mechanism of the present invention, the guiding and transmission of the upright posts can be achieved. The upright posts can reach the storage frame through the guiding channels and be stored on the storage frame. The electronically controlled propulsion telescopic control rod can push the upright posts through the front plate, and at the same time drive the moving plate to move along. When the upright posts reach the frontmost position, the limiting mating groove plate no longer limits the bottom of the moving plate. At this time, the moving plate can rotate through the spring shaft seat. Then the upright posts continue to be pushed and reach the assembling and adjusting mechanism. After that, the limiting mating groove plate is reset under the control of the return spring. Before the transmission of the upright posts, the control motor can control the rotation of the driving gear disc, causing the two limiting pushing guide plates to move symmetrically horizontally to center-align the upright posts, which is more conducive to the subsequent splicing and processing purposes.

Under the processing of the welding robot 29, automatic welding processing is carried out. The assembly combination structure 3 is combined and arranged through the assembly parts 28 and the welding robot 29. Welding robots 29 are provided at the four corners of the assembly parts 28 for the welding processing of the column 30 and the door panel 31. After the column 30 and the door panel 31 are welded, a door panel column welded body 19 is formed.

[0050] like Figure 5 As shown, a cylinder 21 is fixedly installed on the top frame 20, and the cylinder 21 controls the telescopic adjustment of the docking seat 22. The docking seat 22 is fixedly connected to a stable connecting frame 23 on the side away from the cylinder 21, and a stepping motor 24 is fixedly installed on the side end of the stable connecting frame 23.

The positions of the adjusting shaft 25, the telescopic limit card seat 26, and the limiting outer frame 27 are adjusted. At the same time, the stepping motor 24 can drive the rotating adjusting shaft 25 to rotate, so that the rotating adjusting shaft 25 can adjust the flipping of the door panel column welding body 19 through the telescopic limit card seat 26 and the limiting outer frame 27, and the telescopic limit card seat 26 can be telescopically adjusted on the limiting outer frame 27, so as to limit the door panel column welding body 19. The setting of the top frame 20 can carry out the bearing support work of the cylinder 21. Welding robots 29 are installed at the four corners of the assembly part 28 to perform welding work;

[0051] like Figure 7As shown in the figure, the column loading control mechanism 32 is used for the transmission of the door panel 31, and the door panel loading control mechanism 34 is used for the transmission of the column 30. The column 30 and the door panel 31 can be assembled and combined. There are two column loading control mechanisms 32 and two door panel loading control mechanisms 34, which are symmetrically distributed. The assembly adjustment mechanism 33 is arranged at the center of the column loading control mechanism 32 and the door panel loading control mechanism 34. Through the assembly adjustment mechanism 33, the column 30 and the door panel 31 are assembled, and at the same time, the height positions of the column 30 and the door panel 31 can be changed.

The displacement folding frame 36 is arranged in a right-angled bending structure. A push main rod 39 is fixedly connected to the side end of the displacement folding frame 36. A storage seat 38 is fixedly connected to the top of the chassis 35. The hydraulic telescopic regulator 37 controls the position of the push main rod 39 through the displacement folding frame 36, so that the push main rod 39 can feed the door panel 31 in the storage seat 38. The chassis 35 in the column loading control mechanism 32 provides bottom support. Through control, the hydraulic telescopic regulator 37 can drive the displacement folding frame 36 to expand and contract. The displacement folding frame 36 is fixed to the push main rod 39 and can push the door panel 31 to move. At the same time, the push main rod 39 can limit and support the door panel 31 in the storage seat 38, so as to carry out the orderly feeding work of the door panel 31.

[0052] Such as Figure 9As shown, the assembly adjustment mechanism 33 includes a supporting main board 40. A hydraulic lifting base 46 is provided at the bottom of the supporting main board 40. The hydraulic lifting base 46 changes the position of the displacement adjustment plate 41 by telescoping. A positioning main seat 44 is installed in the middle of the displacement adjustment plate 41. The positioning main seat 44 controls the telescopic adjustment of the contact push block 42 through a hydraulic adjustment rod 43. An extension plate 45 is fixedly provided at the front end of the positioning main seat 44. The supporting main board 40 is fixed to the chassis 35 for support connection. An auxiliary hydraulic adjustment plate seat 74 is also telescopically controlled on the displacement adjustment plate 41. Through the telescopic adjustment of the auxiliary hydraulic adjustment plate seat 74, the door panel column welded body 19 can be pushed for secondary height adjustment. The hydraulic lifting base 46 in the assembly adjustment mechanism 33 can drive the displacement adjustment plate 41 for height adjustment. At the same time, the auxiliary hydraulic adjustment plate seat 74 can be controlled to perform secondary height adjustment to change the position of the door panel column welded body 19, facilitating the lifting of the door panel column welded body 19 to the processing position for cooperation with the transposition structure 2 for convenient turning adjustment. At the same time, the positioning main seat 44 can control the position of the contact push block 42 through the hydraulic adjustment rod 43. When the door panel 31 is pushed by the pushing main rod 39, it can squeeze the contact push block 42 for positioning, enabling the door panel 31 to reach the designated processing position.

[0053] As Figure 12As shown, the door panel loading control mechanism 34 includes a loading control part 47 and a propulsion guiding part 48. The loading control part 47 inside the door panel loading control mechanism 34 conducts the guiding and depositing work of the column 30. The propulsion guiding part 48 can conduct the guiding and transmission process of the column 30. The loading control part 47 is used for the loading control of the column 30, and the propulsion guiding part 48 is used for the propulsion of the column 30, so that the column 30 reaches the assembly and adjustment mechanism 33. A protective partition frame 61 is fixedly connected to the side end of the guiding channel 49, and the front end of the guiding channel 49 is communicated with the storage frame 52. A driving guide shaft 51 is rotatably connected to the protective partition frame 61 at a position close to one side of the guiding channel 49, and a limiting tooth sleeve 50 is fixedly connected to the driving guide shaft 51. The driving guide shaft 51 is driven by a motor. A pushing and limiting guiding plate 60 is telescopically connected to the side end of the protective partition frame 61.

The bottom of the storage frame 52 is blocked by the hydraulic control partition frame 54, so as to conduct the Guo Ze transmission process of the column 30. The lower end of the guiding channel 49 is supported by a bearing combination seat 59. The guiding channel 49 inside the loading control part 47 can conduct the guiding and transmission of the column 30, so that the column 30 moves along the guiding channel 49. The limiting tooth sleeve 50 and the driving guide shaft 51 can rotate through control, and the limiting tooth sleeve 50 limits the column 30. Then, through the rotation of the limiting tooth sleeve 50 and the driving guide shaft 51, the limit can be cancelled, so that the column 30 continues to move and reaches the inside of the storage frame 52. At the same time, the lifting control loading guide rod 57 can control the height adjustment of the hydraulic control partition frame 54, and the hydraulic control partition frame 54 can also be telescopically adjusted, so that the column 30 falls and reaches the platform frame 66. At the same time, the toothed plate 53 meshes with the driving gear disk 69, which can make the toothed plate 53 move and adjust. When the toothed plate 53 moves and adjusts, it can change the positions of the limiting pushing guide plate 55, the cooperative guide plate 56, the cooperative guide rod 58, and the pushing and limiting guiding plate 60 to realize the limitation of the column 30. The pushing and limiting guiding plate 60 can center and press the column 30 transmitted on the guiding channel 49. At the same time, when the limiting pushing guide plate 55 is centered, it can center and align the column 30 on the platform frame 66. When the toothed plate 53 moves and adjusts, it drives the cooperative guide plate 56, the limiting pushing guide plate 55, the cooperative guide rod 58, and the pushing and limiting guiding plate 60 to move together. The pushing and limiting guiding plate 60 can limit the column 30 on the guiding channel 49. When the limiting pushing guide plate 55 moves, it can center and adjust the column 30 transmitted at the bottom.

[0054] As Figure 13As shown in the figure, an electric control propulsion telescopic control rod 63 is installed on the stabilizing block seat 62, and a front plate 65 is provided with a limit at the front end of the electric control propulsion telescopic control rod 63. The front plate 65 slides on the platform frame 66, and a limit fitting groove plate 70 is fixedly connected to the side end of the platform frame 66. A protective frame 64 is fixedly connected to the side end of the limit fitting groove plate 70. A bottom support combined frame 67 is fixedly connected to the bottom of the platform frame 66. A control motor 68 is installed at the central internal position of the bottom support combined frame 67, and a driving main gear disc 69 is connected to the control motor 68. The main gear disc 69 is meshed and connected with a toothed plate 53. A spring shaft seat 72 is slidably connected to the limit fitting groove plate 70. A moving plate 71 is hinged to the side end of the spring shaft seat 72. A return spring 73 is elastically connected to the rear end of the moving plate 71, and the bottom of the return spring 73 is connected to the limit fitting groove plate 70 through a seat body for limit connection.

[0055] As Figure 14 shown in the figure, a horizontal groove is provided on the limit fitting groove plate 70. The spring shaft seat 72 slides in the horizontal groove on the limit fitting groove plate 70. The column 30 is pushed by the front plate 65, and the front end of the column 30 is connected to the moving plate 71. When the moving plate 71 reaches the front position of the limit fitting groove plate 70, the moving plate 71 at this time can be flipped and adjusted through the spring shaft seat 72, and the column 30 is slidably adjusted through the top of the flipped moving plate 71. A groove body for the movement of the spring shaft seat 72 is provided on the limit fitting groove plate 70. The moving plate 71 is provided with a limit on the spring shaft seat 72, and the moving plate 71 can slide on the limit fitting groove plate 70. At this time, the bottom of the moving plate 71 is limited by the limit fitting groove plate 70 and can move horizontally. When reaching the bottom position, the limit fitting groove plate 70 no longer limits the moving plate 71 at this time, so that the moving plate 71 can be flipped through the spring shaft seat 72, thereby canceling the limit on the column 30. At this time, the column 30 can continue to move to the designated position. At the same time, the moving plate 71 is reset through the spring shaft seat 72, and the return spring 73 pulls the moving plate 71 and the spring shaft seat 72 to move back, and continues to perform the secondary transmission process of the column 30.

[0056] Working principle: When in use, the user combines and installs the guiding output structure 1, the matching transposition structure 2, and the assembly combination structure 3. Through the settings of the guiding output structure 1, the matching transposition structure 2, and the assembly combination structure 3, the processing and production of the door panel column welded body 19 are carried out. And the guiding output structure 1 is convenient for the hoisting process after the processing of the door panel column welded body 19. With the setting of the matching transposition structure 2, the transposition adjustment of the door panel column welded body 19 can be carried out, so as to carry out welding fixation at multiple positions. With the setting of the assembly combination structure 3, the automatic splicing work of the door panel column welded body 19 can be carried out, which is convenient for the subsequent welding work;

[0057] Among them, the lead screw 7 inside the guiding output structure 1 can rotate through driving, changing the position of the displacement plate 4 on the combined frame 5 and the inner frame 6. When the displacement plate 4 changes its position, it can drive the lifting limit component 9 to adjust synchronously, and the lifting limit component 9 can limit the door panel column welded body 19, so as to hoist the door panel column welded body 19 onto the designated guiding belt 8, facilitating the transmission and guiding work;

[0058] Among them, the movable adjustment frame 10 inside the lifting limit component 9 is threadedly connected to the lead screw 7, so as to be able to cooperate for displacement adjustment. The lower end of the movable adjustment frame 10 can adjust the height of the limiting plate 12 through the movable adjustment frame 10, and the hydraulic control seat 13 can control the telescopic adjustment of the hydraulic control seat 13 on the limiting plate 12 to perform central limiting support for the door panel column welded body 19. At the same time, the motor 16 can drive the turntable 17 and the gear teeth 18 to rotate, so as to limit and clamp the side of the door panel column welded body 19 through the gear teeth 18, facilitating positioning and transmission;

[0059] Among them, the cylinder 21 inside the cooperating conversion structure 2 can change the positions of the docking seat 22, the stable connecting frame 23, the stepping motor 24, the rotating adjustment shaft 25, the telescopic limit clamping seat 26, and the limiting outer frame 27 through telescoping. At the same time, the stepping motor 24 can drive the rotating adjustment shaft 25 to rotate, so that the rotating adjustment shaft 25 performs flipping adjustment of the door panel column welded body 19 through the telescopic limit clamping seat 26 and the limiting outer frame 27, and the telescopic limit clamping seat 26 can telescopically adjust on the limiting outer frame 27, so as to limit and clamp the door panel column welded body 19. The setting of the top frame 20 can perform the bearing and supporting work of the cylinder 21;

[0060] Among them, the assembly combination structure 3 is combined and set through the assembling components 28 and the welding robot 29. Welding robots 29 are provided at the four corners of the assembling components 28 for welding treatment of the columns 30 and the door panels 31. After the columns 30 and the door panels 31 are welded, the door panel column welded body 19 is formed. The setting of the assembling components 28 can automatically assemble the columns 30 and the door panels 31 to realize the preliminary forming treatment work;

[0061] Among them, the column feeding control mechanism 32 inside the assembling component 28 can perform the transmission and guiding of the door panel 31, the door panel feeding control mechanism 34 performs the transmission and guiding work of the column 30, and the assembling adjustment mechanism 33 can perform the cooperative assembly of the column 30 and the door panel 31, and at the same time change the height positions of the column 30 and the door panel 31 to perform the elevated welding treatment work;

[0062] Among them, the chassis 35 inside the column loading control mechanism 32 provides bottom support. The hydraulic telescopic regulator 37 can drive the displacement folding frame 36 to expand and contract through control. The displacement folding frame 36 is fixed to the pushing main rod 39 and can push the door panel 31 to move. At the same time, the pushing main rod 39 can limit and support the door panel 31 inside the storage seat 38, so as to carry out the orderly loading work of the door panel 31;

[0063] Among them, the hydraulic lifting base 46 inside the assembly and adjustment mechanism 33 can drive the displacement adjustment plate 41 to adjust the height. At the same time, the auxiliary hydraulic adjustment plate seat 74 can perform secondary height adjustment through control, changing the position of the door panel column welded body 19, facilitating the lifting of the door panel column welded body 19 to the processing position of the matching transposition structure 2 for convenient turning adjustment. At the same time, the positioning main seat 44 can control the position of the contact push block 42 through the hydraulic adjustment rod 43. The door panel 31 can squeeze the contact push block 42 under the push of the pushing main rod 39, so as to perform positioning processing, enabling the door panel 31 to reach the designated processing position;

[0064] Among them, the loading control part 47 inside the door panel loading control mechanism 34 conducts the guiding and depositing work of the column 30, and the propulsion guiding part 48 can perform the guiding and transmission processing of the column 30;

[0065] Among them, the guiding channel 49 inside the loading control part 47 can conduct the guiding and transmission of the column 30, enabling the column 30 to move along the guiding channel 49. The limit tooth sleeve 50 and the driving guide shaft 51 can rotate through control. The limit tooth sleeve 50 limits the column 30, and then through the rotation of the limit tooth sleeve 50 and the driving guide shaft 51, the limit can be cancelled, enabling the column 30 to continue moving to the inside of the storage frame 52. At the same time, the lifting control loading guide rod 57 can control the height adjustment of the hydraulic control partition frame 54, and the hydraulic control partition frame 54 can also expand and contract, enabling the column 30 to fall to the platform frame 66. At the same time, the toothed plate 53 meshes with the driving toothed disc 69, enabling the movement adjustment of the toothed plate 53. When the toothed plate 53 moves and adjusts, it can change the positions of the limit pushing guide plate 55, the cooperative guide plate 56, the cooperative guide rod 58, and the pushing limit guide plate 60 to realize the limitation of the column 30. The pushing limit guide plate 60 can press the column 30 transmitted on the guiding channel 49 in the middle, and the limit pushing guide plate 55 in the middle can align the column 30 on the platform frame 66 in the middle;

[0066] Among them, the stable block seat 62 can limit the electric control propulsion telescopic control rod 63. At the same time, the electric control propulsion telescopic control rod 63 changes the position of the front plate 65 through expansion and contraction, and the front plate 65 pushes the column 30 for adjustment. The protective frame 64 can support and connect the bearing combination seat 59;

[0067] Among them, the limiting and mating groove plate 70 is provided with a groove for the movement of the spring shaft seat 72. The movement plate 71 is limited on the spring shaft seat 72, and the movement plate 71 can slide on the limiting and mating groove plate 70. At this time, the bottom of the movement plate 71 is limited by the limiting and mating groove plate 70 and can perform lateral movement. When reaching the bottom position, the limiting and mating groove plate 70 no longer limits the movement plate 71, so that the movement plate 71 can be flipped through the spring shaft seat 72, thereby canceling the limit on the upright column 30. At this time, the upright column 30 can continue to move to the designated position. At the same time, the movement plate 71 is reset through the spring shaft seat 72, and the reset spring 73 pulls the movement plate 71 and the spring shaft seat 72 back to continue the transmission process of the secondary upright column 30;

[0068] During use, the user transmits the upright column 30 through the guiding channel 49. When the upright column 30 is transmitted on the guiding channel 49, it can be limited by the rotation adjustment of the limiting tooth sleeve 50 and the driving guide shaft 51 to perform gap feeding work to prevent accumulation. Then, the limiting tooth sleeve 50 and the driving guide shaft 51 cancel the limit, and the single upright column 30 reaches the inside of the storage frame 52 along the guiding channel 49. At this time, the lifting control feeding guide rod 57 controls the hydraulic control partition frame 54 to descend, and at the same time, the electric control propulsion telescopic control rod 63 controls the front plate 65 to move forward to push the upright column 30 to move, and the hydraulic control partition frame 54 cancels the bottom limit. The upright column 30 moves along the platform frame 66. At this time, the control motor 68 controls the driving gear disc 69 to rotate, so that the two tooth plates 53 are adjusted to drive the limiting push guide plate 55 and the push limiting guide plate 60 to move. The limiting push guide plate 55 performs the centering process on the upright column 30 transmitted at the bottom, and the push limiting guide plate 60 performs the centering process on the upright column 30 with the upper end limited by metal. The front end of the upright column 30 contacts the movement plate 71 and pushes the movement plate 71 to move along. The movement plate 71 slides on the limiting and mating groove plate 70 through the spring shaft seat 72. When reaching the front end position of the limiting and mating groove plate 70, the lower end of the movement plate 71 no longer contacts the limiting and mating groove plate 70. At this time, the movement plate 71 can rotate on the spring shaft seat 72. The front plate 65 continues to push the upright column 30 to move. At the same time, the movement plate 71 is flipped and reset on the spring shaft seat 72. At the same time, the reset spring 73 controls the movement plate 71 to pull back to reach the reset position. The front plate 65 controls the upright column 30 to continue to move to the extension plate 45 position for limiting support;

[0069] After that, the hydraulic telescopic regulator 37 controls the contraction of the displacement folding frame 36, causing the driving main rod 39 to move on the chassis 35, enabling the door panel 31 in the storage seat 38 to be pushed and reach the displacement adjustment plate 41. At the same time, one side of the door panel 31 contacts the contact push block 42. Under the pressing action of the driving main rod 39, the column 30 and the door panel 31 can be aligned and spliced to achieve combined processing. During splicing, the hydraulic adjusting rod 43 can contract and adjust through the positioning main seat 44 at this time, so as to cooperate with the splicing work;

[0070] At this time, the splicing of the column 30 and the door panel 31 is completed. After that, the hydraulic lifting base 46 controls the displacement adjustment plate 41 to move upward to the specified height. At this time, the welding robot 29 performs welding processing on the connection position;

[0071] After that, the auxiliary hydraulic adjustment plate seat 74 can continue to perform the height adjustment of the door panel column welded body 19. At this time, the air cylinder 21 controls the telescopic limit clamping seat 26, the limiting outer frame 27, and the rotating adjustment shaft 25 to contact the door panel column welded body 19. At the same time, the telescopic limit clamping seat 26 performs limiting clamping. After that, the stepping motor 24 drives the rotating adjustment shaft 25 to rotate, causing the door panel column welded body 19 to be turned over. After that, it continues to reach the auxiliary hydraulic adjustment plate seat 74, and the auxiliary hydraulic adjustment plate seat 74 resets and continues to perform welding processing;

[0072] After the welding processing is completed, the auxiliary hydraulic adjustment plate seat 74 is lifted again. At the same time, the hydraulic lifting rod 11 descends, and the hydraulic control seat 13 controls the extension of the load-bearing guide rod 14 to support the center bottom of the door panel column welded body 19. At the same time, the motor 16 drives the turntable 17 and the gear teeth 18 to rotate, and the gear teeth 18 are clamped and limited with the door panel column welded body 19, so as to perform the limiting connection of the door panel column welded body 19. After that, the hydraulic lifting rod 11 resets, the lead screw 7 rotates, drives the displacement plate 4 and the lifting limit component 9 to move, places the door panel column welded body 19 on the guiding belt 8, and performs the automatic transmission processing of the door panel column welded body 19 through the guiding belt 8 to complete the work.
