Description

Technical Field

[0001] This utility model relates to the field of welding technology for protective airtight doors, and more specifically, to a welding positioning fixture for protective airtight doors. Background Technology

[0002] In civil defense engineering construction, airtight doors are often used as partition devices for civil defense passages, and steel structure double-leaf protective airtight doors with movable thresholds are one of them. When industrially producing airtight doors, the steel structure needs to be positioned. When welding the positioned steel structure into an integral airtight door structure, for steel structure airtight doors, it is usually necessary to weld the frame of the airtight door and various connecting parts on the airtight door. Therefore, welding positioning fixtures are used.

[0003] A search revealed a welding positioning fixture for a steel structure double-leaf protective airtight door with a movable threshold, with publication number CN222269168U. The specification states: "The output end of the electric push rod drives the upright plate to move inward, causing the U-shaped plate to clamp and fix the airtight door. The output shaft of the servo motor drives the rotating shaft to rotate on the upright plate through bearings, adjusting the airtight door to a horizontal position with the workbench and fixing it. At this time, the welding robot can perform welding work on the airtight door and the outer frame, and can also weld various connecting parts on the upper surface of the airtight door. The output shaft of the servo motor rotates 180 degrees, fixing the reverse side of the airtight door. At this time, welding work can be performed on the lower part of the airtight door and the outer frame, and can also weld various connecting parts on the lower surface of the airtight door, facilitating welding."

[0004] However, in actual use, when welding the back of the airtight door, the door will shift when it is flipped because the two sides of its clamping structure are through grooves. This will cause the clamping point to scrape. If the clamping force is increased to prevent it from shifting, the clamping point will deform due to the large clamping force, which will reduce the quality of the airtight door. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a welding positioning fixture for protective airtight doors, which solves the problem that in the prior art, the airtight door will shift during the flipping process, which will cause the clamping point to scrape. If the clamping force is increased to prevent the shift, the clamping point will deform due to the large clamping force, which will reduce the quality of the airtight door.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective airtight door welding positioning fixture, including a machine body, a placement frame fixedly connected to two motors of the machine body, a placement groove opened inside the placement frame, a clamping block slidably connected inside the placement groove, a rubber pad slidably connected to the lower side of the clamping block, a plurality of slots opened inside the rubber pad, a locking block engaging inside the slot, and the locking block slidably connecting inside the clamping block through the rubber pad.

[0007] The clamping block has multiple mounting slots inside, a rotating rod is rotatably connected inside the clamping block, multiple pull ropes are fixedly connected to the outside of the rotating rod, the other end of the pull rope is fixedly connected to the mounting block, the end of the mounting block away from the pull rope is fixedly connected to the slot, and an elastic element is sleeved on the outside of the pull rope.

[0008] Each of the two placement frames has a storage slot on an adjacent side. A scraper is slidably connected inside the storage slot. Multiple slots are provided on the outer side of the scraper. A rod is inserted into the slot and a roller is inserted into the slot. The rod and the roller are interchangeable components. A collection slot is provided at the top of the machine body.

[0009] The rubber pad is slidably connected inside the placement groove, and multiple protrusions are provided on the side of the rubber pad away from the clamping block.

[0010] The mounting block is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0011] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting block.

[0012] The scraper has a "C" shaped structure. After the scraper enters the placement groove, the insertion rod passes through the placement frame and is inserted into the slot.

[0013] In this configuration, after the scraper detaches from the inside of the placement groove, the roller is inserted into the inside of the slot, and the roller rolls on the upper side of the airtight door.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by placing the airtight door inside the placement frame and attaching a rubber pad at the clamping point, the clamping force is evenly distributed on the airtight door, and the airtight door will not shift when it is flipped, thereby avoiding the airtight door being scratched. This ensures that the airtight door maintains its structural integrity when it is flipped and welded, and the welding quality is not affected. Attached Figure Description

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a welding positioning fixture for a protective airtight door, including a body 1. A placement frame 2 is fixedly connected to two motors on the body 1, allowing the placement frame 2 to rotate. The front and rear sides of the placement frame 2 are side walls, ensuring that the sides of the airtight door will not shift when the placement frame 2 is tilted. A placement groove 17 is provided inside the placement frame 2, and a clamping block 3 is slidably connected inside the placement groove 17. The placement groove 17 limits the clamping block 3, preventing it from shifting during sliding. A rubber bushing is slidably connected to the lower side of the clamping block 3. The rubber pad 4 allows the clamping block 3 and the rubber pad 4 to be spliced ​​together. The rubber pad 4 is slidably connected inside the placement groove 17. The placement groove 17 limits the rubber pad 4 so that the rubber pad 4 will not shift when sliding. Multiple protrusions are provided on the side of the rubber pad 4 away from the clamping block 3, thereby increasing the contact friction between the rubber pad 4 and the airtight door. Multiple slots 5 are opened inside the rubber pad 4. The slots 5 are fitted with locking blocks 6, and the locking blocks 6 penetrate the rubber pad 4 and are slidably connected inside the clamping block 3, so that the clamping block 3 and the rubber pad 4 can be connected.

[0026] When it is necessary to install the rubber pad 4, the top of the rubber pad 4 is slid against the clamping block 3 so that the bottom of the clamping block 3 is in contact with the top of the rubber pad 4. Then, the locking block 6 is moved towards the slot 5 so that the locking block 6 can penetrate the interior of the rubber pad 4 and the slot 5 and engage, thereby allowing the rubber pad 4 and the clamping block 3 to be stably installed.

[0027] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 6, the clamping block 3 has multiple mounting grooves 7 inside. A rotating rod 11 is rotatably connected inside the clamping block 3. The clamping block 3 limits the rotating rod 11 so that the rotating rod 11 will not deviate when sliding. Multiple pull ropes 8 are fixedly connected to the outside of the rotating rod 11. The pull ropes 8 are slidably connected inside the mounting grooves 7. The mounting grooves 7 limit the pull ropes 8 so that the pull ropes 8 will not deviate when sliding. The other end of the pull rope 8 is fixedly connected to the mounting block 10. The mounting block 10 is slidably connected inside the mounting grooves 7. The mounting grooves 7 limit the mounting block 10 so that the mounting block 10 can slide smoothly. The end of the mounting block 10 away from the pull rope 8 is fixedly connected to the locking groove 5. An elastic element 9 is sleeved on the outside of the pull rope 8. One end of the elastic element 9 is fixedly connected to the inner wall of the mounting groove 7, and the other end of the elastic element 9 is fixedly connected to the mounting block 10.

[0028] When the locking block 6 needs to be pulled, the rotating rod 11 is rotated so that the rotating rod 11 can wind the pull rope 8, thereby causing the pull rope 8 to pull the mounting block 10 to move inward. This causes the mounting block 10 to compress the elastic element 9 and deform, thereby pulling the locking block 6 to disengage from the groove 5 and the inside of the rubber pad 4. Conversely, by releasing the rotating rod 11, the elastic element 9 can be reset, thereby causing the rotating rod 11 to push the mounting block 10 to move outward, so that the mounting block 10 can push the locking block 6 through the rubber pad 4 and engage with the inside of the groove 5.

[0029] Example 3: Based on Example 2, in order to clean the other side of the sealed door during welding, a storage groove 12 is provided on the adjacent side of each of the two placement frames 2. A scraper 13 is slidably connected inside the storage groove 12, providing installation space for the scraper 13. The scraper 13 has a "C" shaped structure, allowing the inner wall of the scraper 13 to clean the surface of the sealed door. Multiple slots 15 are provided on the outer side of the scraper 13, and a rod 14 is inserted into the slot 15, along with a roller 16. The rod 14 and the roller 16 are mutually... After the replacement component, the scraper 13 enters the placement slot 17, and the insertion rod 14 passes through the placement frame 2 and is inserted into the slot 15, so that the scraper 13 can be installed on the inner wall of the storage slot 12. After the scraper 13 is disengaged from the placement slot 17, the roller 16 is inserted into the slot 15 and the roller 16 rolls on the upper side of the airtight door, so that the storage slot 12 can move on the airtight door, thereby cleaning the airtight door. The top of the machine body 1 is provided with a collection slot 18, which is used to collect the debris after cleaning.

[0030] When the storage slot 12 is needed to clean the airtight door, the insert rod 14 is pulled to disengage from the slot 15 and the inside of the placement frame 2, thereby pulling the storage slot 12 so that the inner wall of the storage slot 12 fits against the airtight door. Then, the roller 16 is inserted into the corresponding slot 15 so that the outside of the roller 16 rolls on the surface of the airtight door, thereby pulling the storage slot 12 to clean the airtight door. The cleaned welding slag and other impurities fall into the collection slot 18.

[0031] The working process of this utility model is as follows:

[0032] When welding the airtight door, the airtight door is placed inside the placement frame 2, with its side walls fitting against the front and rear sides of the inner walls of the placement frame 2. Then, by rotating the rotating rod 11, the pull rope 8 is wound around it, causing the pull rope 8 to pull the mounting block 10 inward. This causes the mounting block 10 to compress the elastic element 9, deforming it and simultaneously pulling the locking block 6 out of the slot 5. The top of the rubber pad 4 then fits against the bottom of the clamping block 3, and the rotating rod 11 is released, allowing the elastic element 9 to... The resetting motion causes the rotating rod 11 to push the mounting block 10 outward, which in turn pushes the locking block 6 through the rubber pad 4 and the slot 5 to engage. This allows the rubber pad 4 and the clamping block 3 to be stably installed. At this point, the threaded rod inside the placement frame 2 can be rotated to clamp the door between the clamping block 3 and the rubber pad 4, preventing the door from shifting when it is turned over. This avoids scraping the door and ensures that the door maintains its structural integrity during the turning and welding process, thus ensuring that the welding quality is not affected.
