Description

Technical Field

[0001] This application relates to the technical field of welding platforms, and in particular to an automated auxiliary welding platform for the frame of a civil defense door. Background Technology

[0002] Civil defense doors are the doors used at the entrances and exits of civil defense projects. They consist of a door frame, door panels, and locking mechanisms. The door frame is constructed by welding together C-shaped steel or angle steel. During the welding process, the steel is clamped and positioned using a welding platform to ensure welding accuracy.

[0003] Utility model patent CN215509757U discloses an automatic assembly and welding device for air-raid shelter door accessories. This device includes a support frame, a pneumatic box, a pneumatic slide rail, a pneumatic sliding plate, and a clamping plate. A baffle is provided on the inner edge of the top surface of the support frame. The pneumatic box is mounted on the support frame, with one end connected to the pneumatic slide rail. The pneumatic sliding plate is located inside the pneumatic slide rail, and the clamping plate is connected to the pneumatic sliding plate. When positioning C-shaped steel or angle steel is required, the C-shaped steel or angle steel is placed on the top surface of the pneumatic slide rail. Then, the pneumatic box is controlled to draw in air under negative pressure, causing the pneumatic sliding plate to retract. The clamping plate then moves the C-shaped steel or angle steel towards the baffle, ultimately achieving assembly and docking under pneumatic pressure, and clamping and positioning it under the action of the clamping plate.

[0004] However, since the position of the baffle of the above welding device on the support frame is fixed, it can only be used for door frames of a certain size and cannot meet the positioning needs of door frames of different sizes, thus its application range is relatively limited. Summary of the Invention

[0005] The purpose of this application is to provide an automated auxiliary welding platform for the door frame of civil defense doors, which solves the problem that welding devices in related technologies cannot adapt to the positioning needs of door frames of different sizes and have a limited application range.

[0006] The automated auxiliary welding platform for the frame of a civil defense door provided in this application adopts the following technical solution:

[0007] An automated auxiliary welding platform for air-raid shelter door frames includes:

[0008] Lateral translation component;

[0009] The support member is provided in two parts, and the lateral translation component is connected to the two support members. The lateral translation component is used to drive the two support members to move in opposite directions or in opposite directions.

[0010] The first support component has multiple components;

[0011] A vertical drive assembly is provided on the support member. Multiple vertical drive assemblies are provided, each corresponding to one of the multiple first support members. The vertical drive assembly is connected to the first support member and is used to drive the first support member to move up and down.

[0012] A first clamping mechanism is disposed on the first support member and is used to clamp the steel frame of the door frame.

[0013] Longitudinal translation component;

[0014] The second support member is provided in two parts. The longitudinal translation component is connected to the two second support members. The longitudinal translation component is used to drive the two second support members to move in opposite directions or back to back. The second support member is located above the first support member.

[0015] The second clamping mechanism is disposed on the second support member and is used to clamp the steel frame of the door frame.

[0016] By adopting the above technical solution, during the welding of the air-raid shelter door frame, the distance between the two supporting members is adjusted by the horizontal translation component, and the distance between the two second support members is adjusted by the vertical translation component, so that they match the four frame steel members of the air-raid shelter door frame. Then, the vertical drive component drives multiple first support members located between the two second support members to rise until the upper surface of the first support members is flush with the upper surface of the second support members. The four frame steel members of the door frame are then placed on the upper surfaces of the raised first support members and the two second support members, respectively, and clamped and positioned by the first and second clamping mechanisms, thus adapting to the positioning needs of air-raid shelter door frames of different sizes.

[0017] Optionally, the first clamping mechanism is provided in multiple sets. Each first clamping mechanism includes a slide, a first drive assembly, a first clamping plate, and a second drive assembly. The slide is connected to the first support member. The first drive assembly is disposed on the slide and is used to drive the slide to move between multiple first supports members. The first clamping plates are arranged in pairs. The second drive assembly is disposed on the slide and connected to the paired first clamping plates. The second drive assembly is used to drive the paired first clamping plates to move in opposite directions or backwards.

[0018] By adopting the above technical solution, the first clamping mechanism is provided in multiple sets. The first driving component can drive the slide to move between the multiple raised first supports, thereby adjusting the position of the multiple sets of first clamping mechanisms. In turn, the clamping position of the door frame steel placed on the first support can be adjusted to adapt to frame steel of different lengths.

[0019] Optionally, the first support member is provided with a first rack, and the first racks on multiple first support members are interconnected. The first drive assembly includes a rotating shaft, a first worm gear, and a first motor. The rotating shaft is rotatably mounted on the slide table, and the rotating shaft is provided with a first gear and a first worm wheel. The first gear meshes with the first rack, the first worm gear is rotatably mounted on the slide table and meshes with the first worm wheel, and the first motor is fixedly mounted on the slide table and connected to the first worm gear.

[0020] By adopting the above technical solution, the first motor can drive the first worm to rotate, and the first worm can drive the first worm wheel and the first gear to rotate, thereby driving the slide table to slide between multiple first support members under the interaction of the first gear and the first rack.

[0021] Optionally, the first clamping mechanism further includes a first lifting seat and a third driving assembly. The third driving assembly is disposed on the slide and connected to the first lifting seat. The slide and the first lifting seat are located below the upper surface of the first support member. The third driving assembly is used to drive the first lifting seat to move up and down. The second driving assembly and the first clamping plate are disposed on the first lifting seat. The upper surface of the first support member is provided with a downwardly extending clamping plate groove, and the first clamping plate can pass through the clamping plate groove.

[0022] By adopting the above technical solution, the first lifting seat can be driven to rise and fall by the third driving component, so that the first clamping plate can be lowered to below the upper surface of the first support before the frame steel is placed on the upper surface of the first support, thereby avoiding the first clamping plate affecting the placement of the frame steel during the process of placing the frame steel on the upper surface of the first support.

[0023] Optionally, the first clamping mechanism further includes a position sensor, which is fixed on the slide. The first support is provided with a sensing part for triggering the position sensor. When the slide moves to a position where the position sensor and the sensing part are directly opposite each other, the first clamping plate is directly opposite the clamping plate groove.

[0024] By adopting the above technical solution, when the slide table is driven to move between multiple first support members by the first drive component, the position of the slide table can be located by the position sensor. Thus, after the slide table stops moving, the first clamping plate can be aligned with the clamping plate groove, so that the first clamping plate can smoothly pass through the clamping plate groove and extend upward.

[0025] Optionally, the third drive assembly includes a threaded sleeve, a second worm gear, and a third motor. The threaded sleeve is rotatably mounted on the slide table, and a second worm wheel is provided on the outer periphery of the threaded sleeve. The second worm gear is rotatably mounted on the slide table and meshes with the second worm wheel. The third motor is fixedly mounted on the slide table and connected to the second worm gear. A stud and a first guide rod are fixedly mounted on the first lifting seat. The threaded sleeve is screwed to the stud, and the first guide rod slides through the slide table.

[0026] By adopting the above technical solution, after the frame steel is placed on the upper surface of the first support, the second worm can be driven to rotate by the third motor, the second worm can be driven to rotate by the second worm wheel and the screw sleeve, and the screw sleeve can drive the stud and the first lifting seat to rise, thereby driving the first clamping plate to rise and move through the clamping plate groove to both sides of the frame steel.

[0027] Optionally, the vertical drive assembly includes a vertical slider, a vertical lead screw, and a vertical drive motor. The support member is provided with a vertical guide rod, the vertical slider is slidably sleeved on the vertical guide rod, the vertical slider is fixedly connected to the first support member, the vertical lead screw is rotatably mounted on the support member, the vertical drive motor is fixedly mounted on the support member and connected to the vertical lead screw, the vertical slider is provided with a lead screw nut, and the vertical lead screw is screwed to the lead screw nut.

[0028] By adopting the above technical solution, the vertical drive motor can drive the vertical lead screw to rotate, and the vertical lead screw can drive the vertical slider to rise and fall along the vertical guide rod, thereby driving the first support component to rise and fall.

[0029] Optionally, the second clamping mechanism is provided in multiple sets. The second clamping mechanism includes a slide, a fourth drive assembly, a second clamping plate, and a fifth drive assembly. The slide is slidably disposed on the second support member. The fourth drive assembly is disposed on the slide and is used to drive the slide to slide along the second support member. The second clamping plates are arranged in pairs. The fifth drive assembly is disposed on the slide and connected to the pair of second clamping plates. The fifth drive assembly is used to drive the pair of second clamping plates to move in opposite directions or backwards.

[0030] By adopting the above technical solution, the slide can be driven to slide along the second support member by the fourth drive component, thereby adjusting the position of multiple sets of second clamping mechanisms, and then adjusting the clamping position of the door frame steel placed on the second support member to adapt to frame steel of different lengths.

[0031] Optionally, the second clamping mechanism further includes a second lifting seat, a lifting drive, a rotating drive, and a support. The lifting drive is fixed on the slide and connected to the second lifting seat. The lifting drive is used to drive the second lifting seat to lift. The rotating drive is fixed on the second lifting seat and connected to the support. The rotating drive is used to drive the support to rotate. The fifth drive assembly and the second clamping plate are disposed on the support.

[0032] By adopting the above technical solution, before placing the frame steel on the upper surface of the second support, the support is rotated by the rotary drive component, and the second clamping plate is placed on the side of the second support. This avoids the second clamping plate affecting the placement of the frame steel during the process of placing the frame steel on the upper surface of the second support.

[0033] Optionally, the fourth drive assembly includes a fourth motor and a second gear. The fourth motor is fixed on the slide, and the second gear is fixedly connected to the output shaft of the fourth motor. The second support is provided with a second rack, and the second gear meshes with the second rack.

[0034] By adopting the above technical solution, the second gear can be driven to rotate by the fourth motor. Under the interaction between the second gear and the second rack, the slide can be driven to slide along the second support, thereby adjusting the position of the second clamping mechanism on the second support.

[0035] In summary, this application includes at least one of the following beneficial technical effects: When performing welding operations using the automated assisted welding platform for the air-raid shelter door frame of this application, firstly, the two support members are driven to move in opposite directions or back-to-back by the horizontal translation component to adjust the distance between the two support members. Then, the two second support members are driven to move in opposite directions or back-to-back by the vertical translation component to adjust the distance between the two second support members, so that the positions of the two support members and the two second support members match the four frame steel members of the air-raid shelter door frame. Next, the multiple first support members located between the two second support members are driven to rise by the vertical drive component until the upper surface of the first support members is flush with the upper surface of the second support members. Then, the four frame steel members of the door frame are placed on the upper surface of the raised first support members and the upper surface of the two second support members, and the four frame steel members are spliced ​​together. Then, the four frame steel members are clamped and fixed by the first clamping mechanism and the second clamping mechanism, thereby achieving the positioning of the door frame steel members. Since the distance between the two support members and the distance between the two second support members are adjustable, it can adapt to the positioning needs of different sized air defense door frames, thereby effectively expanding the application scope of the automated auxiliary welding platform for air defense door frames of this application.

[0069] When performing welding operations using the automated assisted welding platform for the air-raid shelter door frame of this application, the two support members 20 are first driven to move in opposite directions or back-to-back by the horizontal translation component 10 to adjust the distance between the two support members 20. Then, the two second support members 70 are driven to move in opposite directions or back-to-back by the vertical translation component 60 to adjust the distance between the two second support members 70, so that the positions of the two support members 20 and the two second support members 70 match the four frame steel members of the air-raid shelter door frame.

[0082] The upper surface of the first support member 30 is provided with a downwardly extending clamping groove 32, and the first clamping plate 53 can pass through the clamping groove 32. When the slide table 51 is driven to move among the multiple first supports members 30 by the first drive assembly 52, in order for the first clamping plate 53 to be aligned with the clamping groove 32 after the slide table 51 stops moving, so that the first clamping plate 53 can smoothly pass through the clamping groove 32 and extend upward, the position of the slide table 51 can be positioned by the position sensor 57. More specifically, the position sensor 57 is fixed on the slide table 51, and the first support member 30 is provided with a sensing part 33 for triggering the position sensor 57. When the slide table 51 moves to the position where the position sensor 57 and the sensing part 33 are aligned, the first clamping plate 53 is aligned with the clamping groove 32.

[0083] During the process of placing the frame steel of the door frame onto the upper surface of the first support 30, in order to avoid the first clamping plate 53 affecting the placement of the frame steel, the first clamping plate 53 is placed below the upper surface of the first support 30 before the frame steel is placed onto the upper surface of the first support 30, so as to facilitate the placement of the frame steel onto the upper surface of the first support 30.

[0084] After the frame steel is placed on the upper surface of the first support 30, the third motor 563 drives the second worm gear 562 to rotate. The second worm gear 562 drives the second worm wheel 5611 and the screw sleeve 561 to rotate. The screw sleeve 561 drives the stud 551 and the first lifting seat 55 to rise, thereby driving the first clamping plate 53 to rise and move through the clamping plate groove 32 to both sides of the frame steel. Then, the second motor 543 drives the first lead screw 541 to rotate. The first lead screw 541 drives the paired first sliders 542 and the first clamping plates 53 to move in opposite directions to clamp and fix the frame steel.

The fifth drive assembly 84 is used to drive the pair of second clamping plates 83 to move in opposite directions or away from each other.

[0089] The fourth motor 821 drives the second gear 822 to rotate. The interaction between the second gear 822 and the second rack 71 drives the slide 81 to slide along the second support 70, thereby adjusting the position of multiple sets of second clamping mechanisms 80. This allows for adjustment of the clamping position of the door frame steel placed on the second support 70 to accommodate frame steel of different lengths. When clamping the frame steel, pairs of second clamping plates 83 are placed on both sides of the frame steel, and the fifth drive assembly 84 drives the pairs of second clamping plates 83 to move in opposite directions to achieve clamping and fixing of the frame steel.

[0090] In this embodiment, the specific structure of the fifth drive component 84, and the specific connection relationship between the fifth drive component 84, the second clamping plate 83, and the slide 81 are as follows:

[0091] A lifting drive component 86 is fixed on the slide 81 and connected to the second lifting seat 85. The lifting drive component 86 is used to drive the second lifting seat 85 to rise and fall. More specifically, the lifting drive component 86 is a lifting drive cylinder. A third guide rod 851 is fixed on the second lifting seat 85 and slides through the slide 81. A rotation drive component 87 is fixed on the second lifting seat 85 and connected to the support 88. The rotation drive component 87 is used to drive the support 88 to rotate. A fifth drive assembly 84 and a second clamping plate 83 are disposed on the support 88.

[0092] The fifth drive assembly 84 includes a second lead screw 841, a second slider 842, and a fifth motor 843. A fourth guide rod 881 is provided on the support 88, and a pair of second sliders 842 are slidably sleeved on the fourth guide rod 881. The second lead screw 841 is rotatably mounted on the support 88, and the fifth motor 843 is fixed on the support 88 and connected to the second lead screw 841. The second lead screw 841 has two sets of external threads with opposite directions of rotation. The second sliders 842 are arranged in pairs, and each second slider 842 has a second nut. The second nuts on the pair of second sliders 842 are respectively screwed into the two sets of external threads with opposite directions of rotation on the second lead screw 841. A pair of second clamping plates 83 are respectively fixed on the pair of second sliders 842.

[0093] During the process of placing the frame steel of the door frame onto the upper surface of the second support 70, in order to avoid the second clamping plate 83 affecting the placement of the frame steel, the second clamping plate 83 is placed on the side of the second support 70 before placing the frame steel onto the upper surface of the second support 70, so as to facilitate the placement of the frame steel onto the upper surface of the second support 70.

[0094] After the frame steel is placed on the upper surface of the second support 70, the rotation drive 87 drives the support 88 to rotate, rotating the second clamping plate 83 above the frame steel. Then, the lifting drive 86 drives the support 88 to descend, causing the pair of second clamping plates 83 to descend to both sides of the frame steel. Next, the fifth motor 843 drives the second lead screw 841 to rotate, which in turn drives the pair of second sliders 842 and second clamping plates 83 to move in opposite directions, clamping and fixing the frame steel.

[0095] The implementation principle of the automated assisted welding platform for the frame of a civil defense door in this embodiment is as follows: When it is necessary to position the frame steel of the civil defense door before welding, the two support members 20 are first driven to move in opposite directions or back to back by the horizontal translation component 10 to adjust the distance between the two support members 20. Then, the two second support members 70 are driven to move in opposite directions or back to back by the vertical translation component 60 to adjust the distance between the two second support members 70 so that the positions of the two support members 20 and the two second support members 70 match the four frame steels of the civil defense door frame.

[0096] Next, the vertical drive assembly 40 drives the multiple first support members 30 located between the two second support members 70 to rise until the upper surface of the first support member 30 is flush with the upper surface of the second support member 70. Then, the four frame steel members of the door frame are placed on the upper surface of the raised first support member 30 and the upper surface of the two second support members 70 respectively, and the four frame steel members are joined together.

[0097] Next, the first drive assembly 52 drives the slide 51 to move between the multiple raised first support members 30, adjusting the positions of the multiple sets of first clamping mechanisms 50. Then, the third drive assembly 56 drives the first lifting seat 55 to rise, causing the paired first clamping plates 53 to extend upward through the clamping plate groove 32 and move to both sides of the frame steel. Then, the second drive assembly 54 drives the paired first clamping plates 53 to move in opposite directions, clamping and fixing the frame steel placed on the upper surface of the first support member 30.

[0098] Next, the fourth drive assembly 82 drives the slide block 81 to slide along the second support member 70, adjusting the position of the second clamping mechanism 80. Then, the rotation drive assembly 87 drives the support 88 to rotate, rotating the second clamping plate 83 above the frame steel. Next, the lifting drive assembly 86 drives the support 88 to descend, causing the paired second clamping plates 83 to descend to both sides of the frame steel. Finally, the fifth drive assembly 84 drives the paired second clamping plates 83 to move in opposite directions, clamping and fixing the frame steel, completing the clamping and positioning of the frame steel of the air-raid shelter door.
