Description

Technical Field

[0001] This utility model relates to the field of air defense doors, and in particular to an automatic welding equipment for air defense doors. Background Technology

[0002] Civil defense doors, also known as entrance doors for civil defense projects, are essential facilities for entering protected areas during natural disasters such as war and earthquakes. With the acceleration of urbanization and the increase in population density, civil defense construction has become increasingly important. As an important component of civil defense projects, civil defense doors are being used more and more widely. They can be used not only for the protection of public places such as basements, subways, and tunnels, but also for the protection of residential buildings, improving the overall protection capabilities of the city. The production process of civil defense doors requires high-precision welding technology. With the continuous increase in demand for civil defense doors, large-scale production has become an inevitable trend. Therefore, by introducing advanced automatic welding equipment and technology, the automation and intelligence level of the civil defense door production industry can be improved.

[0003] Among them, Chinese utility model patent with publication number CN219310541U discloses a welding fixture for a civil defense door frame, including a fixing component and a flipping component. The flipping component includes a mounting frame, a rotating shaft, a column, and a drive motor. The rotating shaft is located at the axis of the mounting frame and is fixedly connected to the mounting frame. The column is located at the end of the rotating shaft and is rotatably connected to the column. The drive end of the drive motor is fixedly connected to the end of the rotating shaft. There are multiple sets of fixing components, which are evenly spaced on the mounting frame. The fixing components are used to fix the civil defense door frame.

[0004] The aforementioned prior art has the following drawbacks: by driving the double threaded rod with the drive motor to move the two clamping plates in opposite directions to clamp and fix the air-raid shelter door, the air-raid shelter door will gradually detach from the surface of the mounting frame during the bidirectional movement of the two clamping plates. This causes instability of the air-raid shelter door when adjusting the angle for welding or flipping it for welding, thereby reducing the welding accuracy. Furthermore, the position and spacing of the fixing components in the above technology are fixed, and when the air-raid shelter door is placed inside for welding, it is impossible to effectively fix all four sides of it, further affecting the welding accuracy. It is also not compatible with welding air-raid shelter doors of different specifications, reducing the versatility of its welding equipment. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide an automatic welding equipment for air defense doors, which improves the stability of air defense doors when they are being welded at an adjusted angle or flipped over, and is also compatible with welding air defense doors of different sizes.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an automatic welding equipment for air defense doors, including: a support beam and a drive mechanism for driving its rotation, wherein not less than two support arms are connected to both sides of the support beam, a welding robot is provided on one side of the support beam, and end clamping components and a double-rod cylinder for driving its movement are connected to the top two ends of the support beam, and not less than two side clamping components are connected to the top of the support arms, and the device also includes a drive mechanism for driving the side clamping components to move.

[0007] The side clamping assembly includes a T-shaped seat and a rotary clamping cylinder connected to its top. A clamping block is connected to the rotary clamping cylinder. Two double-rod cylinders are connected to both sides of the T-shaped seat, and a push-clamping block is connected to the extended end of the two double-rod cylinders.

[0008] By adopting the above technical solution, the support beam and support arm work together to provide a stable support platform for the air defense door. The drive mechanism drives the support beam to rotate, so as to angle or flip the air defense door, enabling the welding robot to perform multi-angle welding. In addition, the double-rod cylinder drives the end clamping component to move between the two ends of the top of the support beam to fix the two ends of the air defense door and prevent it from moving. It can also adapt to air defense doors of different lengths. The drive mechanism drives the side pressing component to move, so as to fix it to air defense doors of different widths. At the same time, the rotating pressing cylinder drives the pressing block to move up and down and rotate, so as to fix and press the surface of the air defense door to ensure that the air defense door remains stable during the welding process.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the end clamping assembly includes an H-shaped moving block, the top inner cavity of the H-shaped moving block is rotatably connected to a swing arm via a pin, guide rails are respectively connected to both sides of the end of the support beam, sliders are slidably connected to the guide rails, the sliders are respectively connected to both sides of the bottom inner cavity of the H-shaped moving block, the top of the swing arm is provided with a movable clamping component and an adjusting component for driving its up and down movement, when the bottom end of the swing arm is tilted upward, its bottom end is located outside the top inner cavity of the H-shaped moving block and close to the welding robot, when the bottom end of the swing arm is in a horizontal state, its bottom end is located inside the top inner cavity of the H-shaped moving block, the movable clamping component includes a universal ball joint rod rotatably connected to the inner side of the mounting sleeve, the bottom end of the universal ball joint rod is connected to a pressure plate, and the bottom of the pressure plate is connected to a rubber pad.

[0010] By adopting the above technical solution, the double-rod cylinder drives the H-shaped moving block to move and contact and fix the two ends of the air-raid shelter door. During this process, the bottom end of the swing arm contacts the end of the air-raid shelter door. As the H-shaped moving block gradually moves towards the air-raid shelter door, the swing arm swings continuously to adjust the angle. At this time, the ball head of the universal ball joint adjusts the angle by moving the installation sleeve, so that the pressure plate is in close contact with the surface of the air-raid shelter door. With the deformation of the rubber pad, damage to the surface of the door body is prevented during the pressing process, and a stable fixing force is provided. At the same time, the movable pressing part is adjusted by the adjusting component to adapt to the air-raid shelter door of different thicknesses for fixing. When the H-shaped moving block is in close contact with the end of the air-raid shelter door, the bottom end of the swing arm swings into the top inner cavity of the H-shaped moving block.

[0011] In a preferred embodiment, the present invention can be further configured such that: the adjusting member includes an adjusting screw threaded through the top of the swing arm, the top of the adjusting screw is connected to a handle, and the bottom is connected to a mounting sleeve.

[0012] By adopting the above technical solution, rotating the handle drives the adjusting screw to move up and down, adjusting the height of the movable clamping part in order to achieve precise fixation of the door frame, while adapting to air-raid shelter doors of different thicknesses.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the second drive mechanism includes a movable groove formed at the top of the support arm, a threaded rod is rotatably connected in the movable groove, a servo motor is installed at the end of the support arm away from the support beam, the output shaft of the servo motor is connected to the threaded rod, the threaded rod is threaded through a T-shaped seat, and the T-shaped seat is slidably connected to the support arm.

[0014] By adopting the above technical solution, the moving groove provides a track for the movement of the T-shaped seat, ensuring the stability of the T-shaped seat during the movement process. The servo motor drives the threaded rod to rotate, causing the T-shaped seat to move within the moving groove, thereby achieving precise fixation of the side of the door body. At the same time, it can be adapted to different widths of air-raid shelter doors for welding and fixing.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the drive mechanism includes two supports, each with a rotating disk connected to an opposite side of the support, and an opposite end of the rotating disk connected to a support beam. A drive device is installed on the side of one of the supports away from the support beam, and the output end of the drive device is connected to the rotating disk. A reinforcing rib is symmetrically connected to the rotating disk, and the reinforcing rib is connected to the support beam. The reinforcing rib is located below the guide rail and does not contact the H-shaped moving block.

[0016] By adopting the above technical solution, the driving device drives the rotating disk to rotate, so that the rotating disk synchronously drives the support beam to flip, and under the action of the reinforcing rib, the stability and load-bearing capacity of the rotating disk and the support beam are enhanced.

[0017] In a preferred embodiment, the present invention can be further configured such that: two reinforcing ribs are connected to both sides of the support arm, one end of each reinforcing rib is connected to the support beam, and the horizontal line at the top of the reinforcing rib is located below the bottom horizontal line of the guide rail and the bottom horizontal line of the H-shaped moving block.

[0018] By adopting the above technical solution, the second reinforcing rib enhances the structural stability between the support arm and the support beam, making the entire device more robust when bearing load. Furthermore, the horizontal line at the top of the second reinforcing rib is located below the horizontal line at the bottom of the guide rail and the horizontal line at the bottom of the H-shaped moving block, respectively, avoiding interference between the second reinforcing rib and the guide rail and the H-shaped moving block, thus ensuring the smooth operation of the device.

[0019] In summary, this utility model includes at least one of the following beneficial technical effects of automatic welding equipment for air-raid shelter doors:

[0020] 1. The end clamping assembly is moved between the two ends of the support beam by the double-rod cylinder to fix the end of the air-raid shelter door. The second drive mechanism moves the side clamping assembly to adapt to the air-raid shelter door of different widths for fixing. The double-rod cylinder also works with the side clamping and rotating clamping cylinder to drive the clamping block to move up and down and rotate to fix and clamp the surface of the air-raid shelter door. This ensures that the air-raid shelter door remains stable during the welding process and can also be used to weld air-raid shelter doors of different sizes.

[0021] 2. The rotating disk is driven by a drive device to rotate, so that the rotating disk synchronously drives the support beam and the fixed air-raid shelter door to flip. In conjunction with the welding robot, it can not only improve the positioning accuracy of the air-raid shelter door during multi-angle welding, but also perform flip welding. In addition, the second reinforcing rib further enhances the structural stability of the support beam, reduces vibration and errors during the welding process, and makes the welded joint more flat and firm, effectively improving the overall quality and safety of the air-raid shelter door.

Each side pressing component 70 includes a T-shaped seat 71 and a rotary pressing cylinder 72 connected to its top; a pressing block 75 connected to the rotary pressing cylinder 72; double-rod cylinders 73 connected to both sides of the T-shaped seat 71; and a pushing block 74 connected to the extended end of each double-rod cylinder 73. The drive mechanism 80 includes components located at the top of the support arms 3. The moving slot 81 has a threaded rod 82 rotatably connected inside it. A servo motor 83 is installed at the end of the support arm 3 away from the support beam 1. The output shaft of the servo motor 83 is connected to the threaded rod 82. The threaded rod 82 is threaded through the T-shaped seat 71, and the T-shaped seat 71 is slidably connected to the support arm 3. The first double-rod cylinder 6 drives the end clamping component 50 to move, fixing the end of the air-raid shelter door and adapting it to air-raid shelter doors of different lengths for welding and fixing. The second drive mechanism 80 drives the side pressing component 70 to move, adapting it to air-raid shelter doors of different widths for fixing. The combination of the two improves the welding versatility of the equipment. At the same time, the second double-rod cylinder 73 drives the pushing block 74 to fix the side of the air-raid shelter door, while the rotary pressing cylinder 72 first drives the pressing block 75 to rotate and move downward, fixing and pressing the surface of the air-raid shelter door, thereby keeping the air-raid shelter door stable during the welding process.

[0037] The end clamping assembly 50 includes an H-shaped moving block 51. A swing arm 52 is rotatably connected to the top inner cavity of the H-shaped moving block 51 via a pin. Guide rails 53 are connected to both sides of the end of the support beam 1, and sliders 54 are slidably connected to the guide rails 53. The sliders 54 are connected to both sides of the bottom inner cavity of the H-shaped moving block 51. A movable clamping element 55 and an adjusting element 56 for driving its up-and-down movement are provided at the top of the swing arm 52. When the bottom end of the swing arm 52 is tilted upwards, its bottom end is located outside the top inner cavity of the H-shaped moving block 51 and close to the welding robot 4. When in a horizontal position, its bottom end is located inside the top cavity of the H-shaped moving block 51. The movable clamping component 55 includes a universal ball joint rod 552 rotatably connected to the inner side of the mounting sleeve 551. The bottom end of the universal ball joint rod 552 is connected to a pressure plate 553, and the bottom of the pressure plate 553 is connected to a rubber pad 554. The adjusting component 56 includes an adjusting screw 561 threaded through the top of the swing arm 52. The top end of the adjusting screw 561 is connected to a handle 562, and the bottom end is connected to the mounting sleeve 551. Reinforcing ribs 9 are connected to both sides of the support arm 3, and one end of the reinforcing ribs 9 is respectively... Connected to the support beam 1, the top horizontal line of the reinforcing rib 9 is located below the bottom horizontal line of the guide rail 53 and the bottom horizontal line of the H-shaped moving block 51, respectively. When the double-rod cylinder 6 drives the H-shaped moving block 51 to move and gradually approach the end of the air defense door, the bottom end of the swing arm 52 contacts the end of the air defense door. As the H-shaped moving block 51 gradually moves towards the air defense door, the swing arm 52 continuously swings to adjust its angle until the bottom end of the swing arm 52 swings into the top cavity of the H-shaped moving block 51. At this time, the ball head of the universal ball joint 552 adjusts its angle by moving the installation sleeve 551, so that the pressure plate 553... The rubber pad 554 is in close contact with the surface of the air-raid shelter door, providing a stable fixing force. The adjusting screw 561 is driven to move up and down by rotating the handle 562 to adjust the height of the movable clamping member 55, so as to ensure that air-raid shelter doors of different thicknesses are fixed. During the first use, the movable clamping member 55 is adjusted to ensure that when the H-shaped moving block 51 is in close contact with the end of the air-raid shelter door, the bottom end of the swing arm 52 swings into the top inner cavity of the H-shaped moving block 51, and the pressure plate 553 and the rubber pad 554 are in close contact with the surface of the air-raid shelter door to fix the air-raid shelter door.

[0038] The drive mechanism 20 includes two supports 21. A rotating disk 22 is connected to one of the opposing sides of the supports 21. The opposing ends of the rotating disks 22 are connected to the support beams 1. A drive device 23 is installed on the side of one of the supports 21 away from the support beams 1. The output end of the drive device 23 is connected to the rotating disk 22. Reinforcing ribs 24 are symmetrically connected to the rotating disk 22. The reinforcing ribs 24 are connected to the support beams 1. The reinforcing ribs 24 are located below the guide rails 53 and do not contact the H-shaped moving blocks 51. The drive device 23 is preferably a high-precision servo motor. After the end clamping component 50 and the side pressing component 70 fix the four sides of the air defense door, the drive device 23 drives the rotating disk 22, the support beams 1, and the fixed air defense door to rotate, so as to realize multi-angle adjustment during the welding of the air defense door and cooperate with the welding robot 4 to perform flip welding, thereby improving the welding quality and welding efficiency of the air defense door.

[0039] The implementation principle of this embodiment is as follows: During use, the door frame of the air-raid shelter is placed on the support beam 1 using equipment such as a crane. Then, the H-shaped moving block 51 is driven by the double-rod cylinder 6 to slide along the guide rail 53 to the end of the door frame. As the H-shaped moving block 51 gradually moves towards the air-raid shelter, the swing arm 52 continuously swings to adjust its angle until the bottom end of the swing arm 52 swings into the top cavity of the H-shaped moving block 51. At this time, the ball head of the universal ball joint rod 552 moves and adjusts its angle in the installation sleeve 551, so that the pressure plate 553 and the rubber pad 554 are tightly fixed to the surface of the air-raid shelter. At the same time, the H-shaped moving block 51 also fixes and limits the end of the air-raid shelter. Meanwhile, the double-rod cylinder 73 drives the push block 74 to fix the side of the air-raid shelter, while the rotary pressing cylinder 72 first drives the pressing block 75 to rotate and move downward to fix and press the surface of the air-raid shelter, thereby keeping the air-raid shelter stable during the welding process. It should be noted that when welding the corresponding batch of air-raid shelter doors, i.e. when the equipment is first adjusted and calibrated, the operator first rotates the handle 562 to move the adjusting screw 561 upward, adjusting the pressure plate 553 to the highest position. After the first air-raid shelter door is placed on the support beam 1 and the support arm 3, the double-rod cylinder 6 drives the H-shaped moving block 51 to slide along the guide rail 53 to the end of the door frame. Then, the handle 562 is rotated to move the adjusting screw 561 to press the pressure plate 553 down until it contacts the top of the air-raid shelter door. At this time, the servo motor 83, in conjunction with the threaded rod 82, drives the T-shaped seat 71 to move and adjust it to a suitable position so that the double-rod cylinder 73 drives the push block 74 to fix the side of the air-raid shelter door to prevent it from not making contact. In conjunction with the drive device 23, the rotating disk 22, the support beam 1, and the fixed air-raid shelter door are rotated, and the welding robot 4 performs automated welding operations according to the preset program and path.
