[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This application lowers the center of gravity of the air-raid shelter door by placing the installation frame flat. At the same time, the air-raid shelter door is limited by the moving limit component, so that the air-raid shelter door can move smoothly to the end limit component along the moving limit component. The moving power component drives the flipping power component, so that the flipping power component presses against the other end of the air-raid shelter door, thereby fixing the air-raid shelter door and solving the safety hazards that exist in the manufacturing process of the air-raid shelter door.
[0015] 2. This application uses a flipping power assembly. The first motor drives the drive gear to rotate, pulling the air defense door out of the limiting slide. Then, the second motor drives the second rotating seat to rotate until the air defense door rotates. The air defense door rotates under the clamping action of the first clamping plate and the second clamping plate until the air defense door is placed on the limiting slide. Then, the air defense door is put down, the end clamping assembly is put back in its original position, and the air defense door is clamped again and pushed into the limiting slide groove, realizing the flipping of the air defense door. The air defense door can also be flipped when it is lying flat for processing, so that the air defense door can be processed even when it is lying flat.
[0016] 3. In this application, the stretching end is pulled to make the sliding plate slide in the stretching cavity, so that the stretching end can contact the air-raid shelter door. At the same time, the second measuring sleeve slides on the second measuring bracket, and the first measuring sleeve slides on the first measuring bracket. This allows the measuring box to slide along various positions. The processing position is recorded by the set scale lines, which makes it easy to maintain consistency when processing both sides of the air-raid shelter door through the scale lines during use, and ensures the accuracy of the air-raid shelter door processing.

[0029] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.
[0030] Please see Figure 1-10 As shown, a positioning mechanism for processing air-raid shelter doors includes an installation frame 1, which provides a support base for the entire device. Therefore, a clamping mechanism for the air-raid shelter door is provided on the installation frame 1, specifically including an end limiting component 2, a moving limiting component 3, an end clamping component 7, and a flipping component. Specifically, the air-raid shelter door is limited and slid by the moving limiting component 3 until it slides into the position of the end limiting component 2 for limitation. The moving limiting component 3 is located on the installation frame 1, and the end limiting component 2 is also located on the installation frame 1. A flipping component is slidably provided on the side of the moving limiting component 3, meaning the flipping component can slide along the moving limiting component 3. An end clamping component 7 is provided at the end of the flipping component. Specifically, the end clamping component 7 is used to clamp the air-raid shelter door. Then, the flipping component is moved so that the air-raid shelter door can be moved off the moving limiting component 3. Finally, the flipping component is used to flip the air-raid shelter door, allowing the other side of the air-raid shelter door to be flipped, thereby realizing the processing of the air-raid shelter door.
[0031] Firstly, in this application, the movable limiting component 3 includes a limiting slide 31, which is symmetrically installed on the mounting frame 1. The limiting slide 31 has symmetrically opened limiting grooves 32 on its side, which are used to enable the air defense door to slide on the limiting grooves 32. A limiting roller 33 is rotatably installed inside the limiting groove 32. The air defense door will directly enter the limiting roller 33 and slide laterally on the limiting roller 33, thereby guiding the air defense door.
[0032] Furthermore, the end limiting component 2 includes an arc-shaped limiting plate 22, wherein an end limiting seat 21 is fixed on the mounting frame 1, and an arc-shaped limiting plate 22 is provided on the side of the end limiting seat 21. When the air defense door slides from the limiting roller 33, it will slide onto the arc-shaped limiting plate 22 and be blocked by the arc-shaped limiting plate 22, thereby limiting the frame of the air defense door by the arc-shaped limiting plate 22.
[0033] The end clamping assembly 7 includes a clamping end seat 71, wherein a first clamping plate 75 and a clamping base 72 are fixed to the side of the clamping end seat 71, wherein a clamping telescopic rod 73 is longitudinally fixed on the clamping base 72, wherein a second clamping plate 74 is fixed to the end of the clamping telescopic rod 73, the first clamping plate 75 and the second clamping plate 74 are arranged opposite to each other, and are used to drive the second clamping plate 74 to move longitudinally when the clamping telescopic rod 73 extends, so that the first clamping plate 75 and the second clamping plate 74 clamp and fix the air defense door.
[0034] In this application, the flipping component includes a moving power component 4 and a flipping power component 5. The moving power component 4 is provided on the side of the limiting slide 31 to drive the flipping power component 5 to slide. The flipping power component 5 is provided at the end of the moving power component 4, and the end of the flipping power component 5 is provided with an end clamping component 7, that is, the end of the flipping power component 5 is fixed with a clamping end seat 71.
[0035] The moving power assembly 4 includes a first motor bracket 41, with a bottom sliding plate 45 at its bottom. A bracket slider is mounted on the bottom sliding plate 45 and slidably connected to the mounting frame 1. A first motor 42 is fixed to the first motor bracket 41, driving a drive gear 43. A movable rack 44 is located on the side of the limiting slide block 31, meshing with the drive gear 43 to move the tilting power assembly 5. Specifically, driven by the first motor 42, the drive gear 43 rotates, causing the first motor bracket 41 to move under the meshing action of the drive gear 43 and the movable rack 44, thus driving the tilting power assembly 5 to move laterally.
[0036] The flipping power assembly 5 includes a first sliding rod 51, which is fixedly installed on the side of the first motor bracket 41. A second motor bracket 52 is fixed to the end of the first sliding rod 51 for mounting a second motor 53. The second motor 53 is fixed on the second motor bracket 52 and drives a rotating shaft. A first rotating seat 56 is mounted on the first sliding rod 51, and the rotating shaft and the first rotating seat 56 are rotatably connected. A second rotating seat 55 is rotatably disposed in the middle of the first rotating seat 56, and the second rotating seat 55 is fixed to the first rotating seat 56. A second sliding rod 54 is fixed to the end of the second rotating seat 55, and a clamping end seat 71 is fixed to the end of the second sliding rod 54. Specifically, during use, the second motor 53 drives the rotating shaft, causing the second rotating seat 55 to rotate on the first rotating seat 56, thereby driving the second sliding rod 54 to rotate, causing the clamping end seat 71 to rotate, thus flipping the air defense door to facilitate processing on the other side of the door.
[0037] A measuring component 6 is also provided on the moving limit component 3. The measuring component 6 is used to find, locate and record the processing position of the air defense door, so as to facilitate the processing of the other side of the air defense door after it is flipped over.
[0038] Therefore, the measuring component 6 includes a first measuring bracket 62. First measuring seats 61 are fixed on both sides above the limiting slide 31. A first measuring bracket 62 is positioned between adjacent first measuring seats 61. A first measuring sleeve 63 is slidably mounted on the first measuring bracket 62. The first measuring bracket 62 has evenly distributed scale lines, and the first measuring sleeve 63 can slide on the first measuring bracket 62. A second measuring seat 64 is fixed on the first measuring sleeve 63. A second measuring bracket 65 is fixedly installed between adjacent second measuring seats 64. A second measuring sleeve 66 is slidably mounted on the second measuring bracket 65, and evenly distributed scale lines are also distributed on the second measuring bracket 65. A measuring box 67 is positioned on the other side of the second measuring sleeve 66. Specifically, during use, the measuring box 67 is slidable to reach the processing position on the air-raid shelter door for positioning. During this process, the second measuring sleeve 66 slides on the second measuring bracket 65, while the first measuring sleeve 63 slides on the first measuring bracket 62, thereby enabling the measuring box 67 to slide along various positions.
[0039] Specifically, the measuring box 67 has an internal sliding groove 671 for sliding connection with the second measuring bracket 65. A tension cavity 675 is also provided inside the measuring box 67, within which a tension spring 672 is fixed. A sliding plate 673 is fixed to the other end of the tension spring 672, and the sliding plate 673 slides within the tension cavity 675. A tension end 674 is fixed to the other end of the sliding plate 673, extending out of the measuring box 67. During use, manually pulling the tension end 674 causes the sliding plate 673 to slide within the tension cavity 675, allowing the tension end 674 to contact the air-raid shelter door and directly position the door's processing location. The tension end 674 is tapered.
[0040] In use, this invention first moves the moving power component 4 to the outermost edge of the moving limit component 3. Then, the end clamping component 7 clamps the end of the air-raid shelter door. The moving power component 4, along with the moving limit component 3, moves the air-raid shelter door to the position of the end limit component 2. Next, the measuring component 6 positions and records the processing position of the air-raid shelter door. An external device is used to process the air-raid shelter door. After processing, the moving power component 4 moves the air-raid shelter door out. Then, the flipping power component 5 flips the air-raid shelter door and returns it to the mechanism for positioning and processing. Specifically, as follows:
[0041] First, the clamping telescopic rod 73 is used to drive the second clamping plate 74 to move downward, so that the second clamping plate 74 and the first clamping plate 75 work together to clamp the air defense door. Then, the first motor 42 drives the drive gear 43 to rotate, so that the air defense door is moved under the action of the moving rack 44, pushing the air defense door into the limiting roller 33. The limiting roller 33 limits the movement of the air defense door, thereby pushing the other end of the air defense door onto the arc-shaped limiting plate 22. The arc-shaped limiting plate 22 is used to clamp and fix the air defense door. Then, during use, the stretching end 674 is manually pulled, so that the sliding plate 673 slides in the stretching cavity 675, so that the stretching end 674 can contact the air defense door. At the same time, the second measuring sleeve 66 slides on the second measuring bracket 65, and the first measuring sleeve 63 slides on the first measuring bracket 62, so that the measuring box 67 slides along various positions, and the processing position is recorded by the set scale lines.
[0042] If the other end of the air-raid shelter door needs to be processed, that is, the air-raid shelter door needs to be flipped, the first motor 42 drives the drive gear 43 to rotate, so that the air-raid shelter door is pulled out from the limiting slide 31. Then, the second motor 53 drives the second rotating seat 55 to rotate until the air-raid shelter door rotates. The air-raid shelter door rotates under the clamping action of the first clamping plate 75 and the second clamping plate 74 until the air-raid shelter door is placed on the limiting slide 31. Then the air-raid shelter door is put down, the end clamping assembly 7 is put back in its original position, the air-raid shelter door is clamped again, and the air-raid shelter door is pushed into the limiting slide groove 32 to realize the flipping of the air-raid shelter door.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
