[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-4 This utility model provides a clamping device for welding and processing air defense doors, including a processing plate 1. The processing plate 1 has sliding grooves 2 on both sides of its front and rear ends. The bottom of the processing plate 1 is rotatably connected to a clamping assembly for fixing the air defense door frame. The top of the clamping assembly is slidably connected to the inside of the sliding groove 2. The clamping assembly includes a bidirectional lead screw 4 rotatably connected to the middle of the bottom side of the processing plate 1. Both ends of the outer side of the bidirectional lead screw 4 are threadedly connected to drive rods 5. Both sides of the drive rod 5 are fixedly connected to sliders 3. The bottom of the processing plate 1 is fixedly connected to a forward and reverse motor, the output end of which is fixedly connected to the bidirectional lead screw 4. Four sliders 3 are slidably connected to the inside of the corresponding sliding grooves 2. The inside of the sliders 3 is slidably connected to a connecting rod 10. The bottom of the connecting rod 10 is fixedly connected to a limit block 11. The limit block 11 is slidably connected to the inside of the corresponding side groove 9. The top of the connecting rod 10 is fixedly connected to a clamping plate 12 for fixing the air defense door frame. Support blocks 17 are fixedly connected to all four sides of the top of the processing plate 1. Support feet are fixedly connected to both sides of the bottom of the processing plate 1.

[0020] After the door frame components to be welded are assembled, they are placed on the processing plate 1 and supported by the support block 17. The bidirectional lead screw 4 is rotated by the positive and negative motors, which drives the two drive rods 5 to move inward. The slider 3 slides in the slide groove 2 until the connecting rod 10 drives the clamping plate 12 to move above the door frame.

[0021] Please see Figures 1-4A first electric cylinder 6 is fixedly connected to the center of the bottom of the processing plate 1. A bracket 7 is fixedly connected to its output end. The bracket 7 includes a support plate 8 fixedly connected to both sides. The two ends of the support plate 8 are provided with side grooves 9. The bottom of the clamping assembly is slidably connected to the inner side of the corresponding side groove 9. Side fixing assemblies are fixedly connected to both sides of the processing plate 1. The side fixing assemblies include a second electric cylinder 13 fixedly connected to the outside of the processing plate 1. A rotating seat 14 is fixedly connected to the top of the second electric cylinder 13. A rotating sleeve 15 is rotatably connected to the outside of the rotating seat 14. Several pressure plates 16 are fixedly connected to the outside of the rotating sleeve 15. There are five pressure plates 16 on the outside of the same rotating sleeve 15. The pressure plates 16 are distributed in a ring on the outside of the rotating sleeve 15 and their length gradually increases.

[0022] When the connecting rod 10 moves, the limiting block 11 slides within the side groove 9 to ensure that the limiting block 11 is always located inside the support plate 8. The rotating sleeves 15 on both sides are manually rotated so that the pressure plate 16, which is appropriately fixed to the length of the door frame, rotates to the top of the door frame. Simultaneously, the first electric cylinder 6 and the second electric cylinders 13 on both sides are activated, so that the bracket 7 and the support plate 8 drive all the connecting rods 10 and the clamping plate 12 to descend through the limiting block 11. At the same time, the second electric cylinder 13 drives the pressure plate 16 to descend, clamping and fixing all parts of the door frame, and then the door frame is further welded.

[0023] When the bidirectional lead screw 4 rotates, it can drive the drive rods 5 on both sides to move synchronously along the preset direction, and cause all the sliders 3 to slide synchronously in the grooves 2 on the processing plate 1. This allows the clamping assembly to be flexibly adjusted according to the actual width of the door frame component, thereby achieving effective adaptation to door frame components of various widths. When the rotating sleeve 15 rotates, the pressure plate 16 will rotate accordingly. Since the lengths of the pressure plates 16 are different, they can rotate to the side of the appropriate length pressure plate 16 according to the distance from the door frame, thereby achieving a firm fixation of door frame components of various lengths. This design not only improves the clamping stability of the equipment for door frame components, but also greatly enhances the versatility and applicability of the equipment, enabling it to easily meet the welding processing needs of various specifications of civil defense door frames.

[0024] The first electric cylinder 6 drives the two support plates 8 to lift and lower via the bracket 7. The side grooves 9 on the support plates 8 cooperate with the limit blocks 11 to drive the four connecting rods 10 and the clamping plates 12 to lift and lower synchronously. With the synergistic effect of the two side fixing components, the door frame components are clamped synchronously in all directions. This allows the equipment to fix all parts of the door frame without setting too many drive components. This not only simplifies the equipment structure and reduces costs, but also improves the operating efficiency and reliability of the equipment, significantly enhancing the practicality of the entire equipment.

[0025] The working principle and usage process of this utility model are as follows: After the door frame components to be welded are assembled, they are placed on the processing plate 1 and supported by the support block 17. The bidirectional lead screw 4 is rotated by the positive and negative motors, which drives the two drive rods 5 to move inward. The slider 3 slides in the slide groove 2 until the connecting rod 10 drives the clamping plate 12 to move above the door frame. When the connecting rod 10 moves, the limiting block 11 slides in the side groove 9 to ensure that the limiting block 11 is always located inside the support plate 8. The rotating sleeves 15 on both sides are manually rotated so that the pressure plate 16, which is suitable for fixing the length of the door frame, rotates to the top of the door frame. At the same time, the first electric cylinder 6 and the second electric cylinders 13 on both sides are started, so that the bracket 7 and the support plate 8 drive all the connecting rods 10 and the clamping plate 12 to descend through the limiting block 11. At the same time, the second electric cylinder 13 drives the pressure plate 16 to descend, clamping and fixing all parts of the door frame. Then the door frame is further welded.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
