Description

Technical Field

[0001] The utility model relates to the field of welding positioning, in particular to a positioning device for welding a civil air defense door frame. Background Art

[0002] Civil defense is also known as civil defense. Civil defense is an internationally accepted term. It refers to the activities of the government mobilizing and organizing the masses to take anti-air raid, disaster prevention and relief measures, implement rescue operations, and prevent and reduce the harm of disasters. Civil defense doors belong to civil defense protection equipment.

[0003] During the production process of civil air defense doors, some components need to be welded to the frame of the civil air defense doors. At this time, a positioning device is needed to position them to ensure that the welding work can proceed normally. By positioning welding, welding will be more efficient during work.

[0004] Most of the existing civil air defense door frame positioning devices are fixed by a slot, and the slot is loosened and tightened by turning the bolts. The civil air defense door frame is heavy and inconvenient to disassemble. The bolts need to be loosened so that the door frame is no longer clamped. This requires greater work intensity and the door frame needs to be removed from the slot, which is time-consuming and labor-intensive and is not conducive to improving production efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] A positioning device for welding a civil air defense door frame, such as Figure 1-5As shown, it includes a workbench 1, a motor box 17 is fixedly installed on one side of the workbench 1, and a rotating rod 4 is movably installed on one side of the motor box 17, first gears 7 are fixedly installed on both ends of the rotating rod 4, and a first tooth plate 6 is arranged on one side of the first gear 7, a first top plate 5 is fixedly installed on one end of the first tooth plate 6, a first tooth plate 6 is fixedly installed on the middle part of the rotating rod 4, and second tooth plates 9 are arranged on both sides of the second gear 8, an inclined block 10 is fixedly installed on one end of the second tooth plate 9, and second top plates 12 are movably installed on both sides of the workbench 1, and the second top plates 12 are fixedly installed on both sides of the workbench 1. A movable rod 11 is fixedly installed at the end, and the movable rod 11 cooperates with the inclined block 10. The rotating rod 4 rotates, so that the first gear 7 drives the first tooth plate 6 to rise. When the first tooth plate 6 rises, it drives the first top plate 5 to move upward. At the same time, the second gear 8 drives the second tooth plate 9 to move to one side, so that the inclined block 10 squeezes the movable rod 11. At this time, the movable rod 11 moves upward and drives the second top plate 12 to move upward. At this time, the door frame is lifted up, and at the same time, the rotating rod 4 rotates to drive the movable plate 2 to move, and the movable plate 2 no longer clamps the door frame.

[0027] See also Figure 1-2 A movable plate 2 is movably installed on one side of the workbench 1, and a ring 3 is fixedly installed on one end of the movable plate 2, a screw rod 16 is fixedly installed on one end of the rotating rod 4, and the ring 3 cooperates with the screw rod 16. By setting the movable plate 2, when the movable plate 2 moves to one side, the door frame can be clamped, so that the door frame is fixed as a whole, avoiding displacement of the door frame during welding, which causes problems affecting welding.

[0028] See also Figure 1 , 3 A limiting groove 15 is provided on one side of the workbench 1, and the limiting groove 15 cooperates with the collar 3. Second movable grooves 14 are provided on both sides of the workbench 1, and the second movable grooves 14 cooperate with the first top plate 5. A first movable groove 13 is provided in the middle of the workbench 1, and the first movable groove 13 cooperates with the second top plate 12. By setting the limiting groove 15, the movement of the collar 3 can be limited by the limiting groove 15, thereby avoiding the movement of the movable plate 2 from being offset. By setting the first movable groove 13 and the second movable groove 14, the movement of the first top plate 5 and the second top plate 12 is limited, so that the first top plate 5 and the second top plate 12 can be more stable when lifting the door frame, thereby avoiding the problem of displacement of the door frame.

[0029] See also Figure 5 One side of the inclined block 10 is set with an inclined surface, and one end of the movable rod 11 is set with an arc surface. The lengths of the two groups of movable rods 11 are different. The inclined block 10 with an inclined surface makes the movable rod 11 smoother when squeezed by the inclined block 10, avoiding jamming, and making the overall operation more stable.

[0030] See also Figure 5The first gear 7 is meshed with the first tooth plate 6, and the second gear 8 is meshed with the second tooth plate 9. The connection between the gears and the tooth plates makes the transmission effect better and avoids the problem of transmission slippage and failure.

[0031] The working principle of the utility model is as follows: the door frame is placed on the top of the workbench 1, and then the motor box 17 is started to rotate the rotating rod 4. When the rotating rod 4 rotates, it drives the first gear 7 to rotate, so that the first tooth plate 6 moves down. When the first tooth plate 6 moves down, it drives the first top plate 5 to move down. At the same time, when the rotating rod 4 rotates, it drives the second gear 8 to rotate, so that the second tooth plate 9 is displaced. When the second tooth plate 9 is displaced, it drives the inclined block 10 to be displaced. At this time, the movable rod 11 loses the limit of the inclined block 10 and moves down, so that the second top plate 12 moves down. At this time, the door frame falls into the interior of the workbench 1. At the same time, when the rotating rod 4 rotates, When the door frame is taken out, the motor box 17 is started to rotate the screw rod 16, so that the sleeve ring 3 is displaced, and the movable plate 2 is driven to clamp the door frame. When the door frame is taken out, the motor box 17 is started to rotate the rotating rod 4, so that the first gear 7 drives the first tooth plate 6 to rise. When the first tooth plate 6 rises, it drives the first top plate 5 to move upward. At the same time, the second gear 8 drives the second tooth plate 9 to move to one side, so that the inclined block 10 squeezes the movable rod 11. At this time, the movable rod 11 moves upward and drives the second top plate 12 to move upward. At this time, the door frame is lifted up, and at the same time, the rotating rod 4 drives the movable plate 2 to move when it rotates, and the movable plate 2 no longer clamps the door frame in a limited position.
