Description

Technical Field

[0001] The present application relates to the technical field of civil air defense door manufacturing, and in particular to a civil air defense door welding platform. Background Art

[0002] The first step in making a civil air defense door is to weld the door frame. When welding the door frame, the four door frame edges need to be spliced ​​and fixed.

[0003] The prior art is to weld several blocks on a platform, insert the door frame edge between the blocks to form a fixed relationship, and then the staff welds two adjacent door frame edges.

[0004] If the manufacturing size of the civil air defense door changes, the block needs to be cut off and then re-welded at the appropriate position; however, this requires cutting the block and re-welding it multiple times, which is inconvenient and reduces work efficiency. Utility Model Content

[0005] In order to facilitate changing the distance between two blocks, the present application provides a civil air defense door welding platform.

[0006] The civil air defense door welding platform provided in this application adopts the following technical solutions:

[0007] A civil air defense door welding platform comprises a working platform, a first stopper and a second stopper, wherein the first stopper and the second stopper are both provided with plug-in blocks, the working platform is provided with a plurality of plug-in slots for the plug-in blocks to be plugged in, and the door frame edge is plugged between the first stopper and the second stopper.

[0008] By adopting the above-mentioned technical solution, the first block and the second block can be fixed on the work platform by plugging the plug-in block and the plug-in groove, so that the door frame edge can be plugged in between the first block and the second block; and by changing the plug-in cooperation between the plug-in block and different plug-in grooves, the distance between the two first blocks and the second blocks can be changed to plug in door frame edges of different thicknesses, and civil defense doors of different widths can be processed.

[0009] Optionally, a rubber baffle is provided on the surface of the working platform, and the rubber baffle covers the surface of the plug-in slot.

[0010] By adopting the above technical solution and setting a rubber baffle, on the one hand, dust can be reduced from entering the plug-in slot; on the other hand, the rubber baffle can be deformed during the process of the plug-in block being plugged into the plug-in slot, thereby improving the stability of the plug-in block being plugged into the plug-in slot.

[0011] Optionally, the plug-in block of the first stopper and the plug-in plate of the second stopper are connected via a mounting plate; the first stopper and the second stopper are slidably mounted on the mounting plate, and the mounting plate is provided with a fixing component for fixing the positions of the first stopper and the second stopper.

[0012] By adopting the above-mentioned technical solution, the plug-in efficiency of the first block and the second block can be improved by connecting the plug-in block of the first block and the plug-in block of the second block; and by slidingly installing the first block and the second block on the mounting plate, the distance between the first block and the second block can be fine-tuned, thereby improving the applicability of the device.

[0013] Optionally, the first stop block is provided with a first rack, the second stop block is provided with a second rack, and the mounting plate is rotatably mounted with a gear, and the gear is meshed with the first rack and the second rack.

[0014] By adopting the above technical solution, the gear is rotated, and the first rack and the second rack are moved closer to each other / farther away from each other under the meshing of the gear, thereby adjusting the distance between the first stopper and the second stopper. Optionally, the fixing assembly includes a sleeve, a movable rod and a first spring, and the mounting plate is provided with a tooth groove for the gear to be inserted; the sleeve is rotatably installed in the tooth groove, the movable rod is movably installed in the sleeve, and the end of the movable rod away from the sleeve is fixed to the gear; the two ends of the first spring are respectively connected to the movable rod and the inner wall of the sleeve, and the elastic force of the first spring drives the gear to be normally inserted into the tooth groove.

[0015] By adopting the above-mentioned technical solution, when the positions of the first stop block and the second stop block are fixed, the gear is inserted into the tooth groove. Since the first rack and the second rack are still in meshing state with the gear, the movement of the first rack and the second rack can be reduced, and the possibility of free movement of the first baffle and the second baffle can be reduced; by setting the first spring, the possibility of the gear detaching from the tooth groove can be reduced, and the stability of the first baffle and the second baffle on the mounting plate can be increased.

[0016] Optionally, a groove is formed on a side of the mounting plate away from the first stopper, a pull rod is slidably installed in the groove, and the pull rod is fixed to the gear.

[0017] By adopting the above technical solution, by opening a pull groove at the bottom of the mounting plate, the pull groove can be hidden when the mounting plate is inserted into the insertion groove, thereby reducing the situation where the distance between the first baffle plate and the second baffle plate changes when the staff accidentally touches the pull rod.

[0018] Optionally, a limiting block is fixed on the outer wall of the movable rod, and a limiting groove for the limiting block to slide is formed on the inner wall of the sleeve.

[0019] By adopting the above technical solution and setting a limit block, when the gear is disengaged from the tooth groove and rotated, the sleeve and the movable rod rotate at the same time, thereby reducing the possibility of the first spring being damaged due to multiple rotations.

[0020] Optionally, scale lines are provided on the surface of the mounting plate.

[0021] By adopting the above technical solution and setting the scale line, the distance between the two baffles can be visually observed, so that the distance between the first baffle and the second baffle adjusted on all mounting plates on the working platform can be kept consistent.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By changing the plug-in cooperation between the plug-in block and different plug-in slots, the first block and the second block can be fixed on the working platform, so that the door frame edge can be plugged between the first block and the second block, and civil air defense doors of different widths can be processed, reducing the possibility of cutting the first block and the second block multiple times during welding, and improving the convenience of welding civil air defense doors of different widths on the platform;

[0024] 2. By providing a rubber baffle, on the one hand, dust can be reduced from entering the plug-in slot; on the other hand, the rubber baffle can be deformed during the plug-in block is plugged into the plug-in slot, thereby improving the stability of the plug-in block in the plug-in slot.
