Description

Technical Field

[0001] This utility model relates to the field of welding fixtures for steel structure door panels, specifically a welding fixture for steel structure door panels. Background Technology

[0002] A civil defense door is a special type of door installed at the entrances and exits of air defense projects or underground spaces. Due to the special nature of the installation location, civil defense doors usually need to have characteristics such as explosion-proof and bulletproof, fireproof and high-temperature resistant, dustproof and waterproof, as well as anti-theft and anti-pry. The part of a civil defense door that can be rotated to open and close is called the door leaf, which is mainly made of steel. The door leaf has two large surfaces. During the manufacturing process of the door leaf, it is usually necessary to weld door lock frames, lock reinforcement parts, hinges, door handles, and door pivots to the two large surfaces of the door leaf.

[0003] There is a welding fixture for steel door panels (application number: 202420332514.6) that saves time and effort, improves welding efficiency, and adapts to the needs of different welding scenarios. However, the above-mentioned problems still exist. When welding the door body, welding fixtures are often required to fix the door body before welding. Due to the large weight of the door body, workers need to lift the door body a considerable distance when loading and unloading it, which is inconvenient for workers to operate and makes it difficult to fix the door body easily. Furthermore, it is not convenient for workers to limit the door body before fixing it, which can easily lead to deviation of the door body and affect the fixing work. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, which requires lifting the door body a high distance when loading and unloading the door body, making it inconvenient for workers to operate, making it difficult for workers to easily fix the door body, making it difficult for workers to limit the door body, and making it easy for the door body to deviate, thus affecting the fixing work. Therefore, a welding fixture for steel structure door leaf is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a welding fixture for a steel door panel, including a base plate. A grooved plate is fixedly connected to one side of the top of the base plate, and an outer shell is fixedly connected to one end of the grooved plate. A square box is provided on one side of the grooved plate, and a vertical plate is fixedly connected to one end of the square box. A gear 1 is rotatably connected to the lower inner wall of the vertical plate on one side via a bearing. A frame is fixedly connected to one end of the gear 1, and one end of the frame is rotatably connected to the lower inner wall of the vertical plate on the other side via a bearing. A gear 2 is meshed above the gear 1, and one end of the gear 2 is fixedly connected to the output end of the motor 3. One end of the motor 3 is fixedly connected to one end of the inner wall of the square box. A lifting structure is provided on one side of the outer shell, and a limiting structure is provided above the base plate.

[0007] Preferably, the lifting structure includes a motor, one end of which is fixedly connected to the lower side of the inner wall of the outer casing. A reel is fixedly connected to the output end of the motor, and a rope is fixedly connected to the outer wall of the reel. A roller is attached to the outer wall of the rope, and the front end of the roller is rotatably connected to the top of the inner wall of the outer casing via a pin. A slider is fixedly connected to one end of the rope, and the outer wall of the slider is slidably engaged with the inner through groove of the slot plate. One end of the slider is fixedly connected to one end of the square box.

[0008] Preferably, the inner wall of the frame is fitted with a housing, one end of the inner wall of the housing is threaded with a lead screw, and one side of the outer wall of the lead screw is threaded with a block.

[0009] Preferably, the front end face of the block is rotatably connected to a diagonal rod via a pin, and the rear end of the diagonal rod is rotatably connected to a clamping plate via a pin.

[0010] Preferably, one side of the outer wall of the clamping plate is slidably engaged with one end of the outer groove of the housing.

[0011] Preferably, the limiting structure includes an inclined block, the bottom of which is fixedly connected to the rear top of the base plate, a grooved block is fitted to the outer wall of the inclined block with a clearance, a baffle is fixedly connected to one end of the grooved block, and a limiting plate is fixedly connected to one side of the front end face of the baffle.

[0012] The welding fixture for steel door panels proposed in this utility model has the following advantages: through the cooperation of the base plate, frame, groove plate, outer shell, square box, and lifting structure, the device can be used by a motor driving a pulley to rotate. The pulley, under the action of gravity, causes the slider to move the square box downward, thereby moving the frame downward. This allows the bottom of the door panel to be moved closer to the base plate, so that when loading and unloading the door panel, it is not necessary to lift the door panel to a high distance. This makes it convenient for workers to operate and makes it easier for workers to fix the door panel.

[0013] By combining the base plate, baffle, limiting plate, groove block, and inclined block, the device can be used to place the baffle and limiting plate by inserting the groove block into the outer wall of the inclined block. The baffle and limiting plate can limit the placement position of the door, making it easier for workers to limit the door and prevent deviations from affecting the fixing work.

A grooved plate 5 is fixedly connected to one side of the top of the base plate 1. A housing 6 is fixedly connected to one end of the grooved plate 5. A square box 10 is provided on one side of the grooved plate 5. A vertical plate 9 is fixedly connected to one end of the square box 10. A gear 11 is rotatably connected to the lower inner wall of the vertical plate 9 on one side through a bearing. The bearing allows the gear 11 to rotate on the lower inner wall of the vertical plate 9 on one side when it is under force. A frame 4 is fixedly connected to one end of the gear 11. One end of the frame 4 is rotatably connected to the lower inner wall of the vertical plate 9 on the other side through a bearing. A gear 2 12 is meshed above the gear 11. One end of the gear 2 12 is fixedly connected to the output end of a motor 3 13. The model of the motor 3 13 depends on the actual use. One end of the motor 3 13 is fixedly connected to one end of the inner wall of the square box 10. A housing 7 is fitted with the inner wall of the frame 4 with a clearance fit.

[0024] A lead screw 15 is threaded onto the inner wall of one end of the housing 7. A block 16 is threaded onto one side of the outer wall of the lead screw 15. A diagonal rod 14 is rotatably connected to the front end of the block 16 via a pin. A clamping plate 8 is rotatably connected to the rear end of the diagonal rod 14 via a pin. A rubber pad is fixedly connected to one side of the outer wall of the clamping plate 8. The outer side of the clamping plate 8 is slidably engaged with the outer groove of one end of the housing 7. The outer groove of one end of the housing 7 limits the clamping plate 8 when it moves up and down under force. A lifting structure 2 is provided on one side of the outer shell 6, and a limiting structure 3 is provided above the base plate 1. The lifting structure 2 does not require the door to be raised a high distance, making it convenient for operators to operate and easy to fix the door. The limiting structure 3 allows operators to limit the door and prevent deviation of the door from affecting the fixing work.

[0025] The lifting structure 2 includes a motor 2a5. One end of the motor 2a5 is fixedly connected to the lower side of the inner wall of the outer casing 6. The model of the motor 2a5 depends on the actual use. A pulley 2a4 is fixedly connected to the output end of the motor 2a5. A rope 2a3 is fixedly connected to the outer wall of the pulley 2a4. A roller 2a2 is attached to the outer wall of the rope 2a3. The front end of the roller 2a2 is rotatably connected to the top of the inner wall of the outer casing 6 through a pin. The pin allows the roller 2a2 to rotate on the top of the inner wall of the outer casing 6 when it is under force. A slider 2a1 is fixedly connected to one end of the rope 2a3. The outer wall of the slider 2a1 is slidably engaged with the inner through groove of the slot plate 5. The inner through groove of the slot plate 5 limits the slider 2a1 when it moves up and down under force. One end of the slider 2a1 is fixedly connected to one end of the square box 10. It is convenient for operators to operate and fix the door relatively easily without having to lift the door a high distance.

[0026] The limiting structure 3 includes an inclined block 304. The bottom of the inclined block 304 is fixedly connected to the top rear of the base plate 1. The outer wall of the inclined block 304 is fitted with a groove block 303. One end of the groove block 303 is fixedly connected to a baffle 301. The top of the baffle 301 is fixedly connected to a handle. A limiting plate 302 is fixedly connected to one side of the front end face of the baffle 301, which facilitates the staff to limit the door and prevent the door from deviating and affecting the fixing work.

[0027] Working principle:

[0028] When fixing the door:

[0029] Insert the slot block 303 into the outer wall of the inclined block 304 to place the baffle 301 and the limiting plate 302. Place the door between the two limiting plates 302. After removing the baffle 301 and putting down the frame 4, place the door inside the frame 4. Place the door between the two clamping plates 8. Rotate the screw 15. The screw 15 drives the block 16 to move outward. The block 16 drives the inclined rod 14 to move. The inclined rod 14 drives the clamping plate 8 to move inward, thereby fixing the door.

[0030] When the door is lifted:

[0031] Motor 2a5 starts working, driving the reel 2a4 to rotate. The reel 2a4 winds up the rope 2a3, which in turn moves the slider 2a1 upward, lifting the door and facilitating welding work on the top of the door. When welding is required on the reverse side, motor 13 starts working, driving gear 12 to rotate. Gear 12 then drives gear 11 to rotate, which in turn drives frame 4 to rotate, thus reversing the door and facilitating welding work on the reverse side.

[0032] Example 2:

[0033] See attached document Figure 1-6 In this embodiment, a welding fixture for a steel door leaf is provided, wherein the lifting structure 2 may further include a curved block 2b2. The rear of the outer wall of the curved block 2b2 is slidably engaged with the through groove of the front end face of the frame 4. The rear end of the curved block 2b2 is fixedly connected to the front end face of the housing 7. A double-ended threaded rod 2b1 is threadedly connected to the upper inner wall of the curved block 2b2. One side of the outer wall of the double-ended threaded rod 2b1 is rotatably connected to a protrusion on one side of the front end face of the frame 4 through a bearing. One end of the double-ended threaded rod 2b1 is fixedly connected to the output end of the second motor 2b3. The model of the second motor 2b3 is determined according to the actual use. The rear end of the second motor 2b3 is fixedly connected to one side of the front end face of the frame 4.

[0034] Working principle:

[0035] Motor 2b3 starts working, driving the double-headed threaded rod 2b1 to rotate. The double-headed threaded rod 2b1 drives the curved block 2b2 to move left and right, and the curved block 2b2 drives the housing 7 to move, thereby facilitating the centering of the door and preventing deviations in the door's fixed position, which would affect the welding work.
