Description

Technical Field

[0001] The utility model belongs to the technical field of fire damper blades, and particularly relates to a positioning device for welding and processing fire damper blades. Background Technique

[0002] Patent Publication No. CN216138381U discloses a positioning device for welding and processing fire damper blades, belonging to the technical field of fire damper processing, including an operating table and a bracket. The operating table is provided with a sunken opening for placing fire damper blades. A rotating shaft insertion groove is arranged below the sunken opening. A limiting first sleeve is arranged on the left side of the sunken opening, and a second sleeve with a clamping function and capable of moving leftward is arranged on the right side. The utility model fixes the fire damper blades by the sleeves on both sides, positions and places the rotating shaft through the rotating shaft suspension part above, so that the welding accuracy can be greatly improved. At the same time, after welding one end, when flipping this end to the rotating shaft insertion groove corresponding to the sunken opening, tip fixation can be realized, and then another rotating shaft is suspended by the rotating shaft suspension part to match the fire damper blade for welding operation. By arranging rollers on the connecting plate, the electric push rod moves more smoothly when pushing the second sleeve, reducing damage to the fire damper blades during the moving and pressing process. The above positioning device can only place and position rotating shafts and blades with fixed sizes, cannot perform positioning welding for rotating shafts and blades with different sizes, and cannot adjust the position of the blades according to different positioning requirements, reducing flexibility. Therefore, we propose a positioning device for welding and processing fire damper blades. Content of the Utility Model

[0019] Please refer to Figure 1-2 , the present utility model provides a positioning device for welding and processing of fire damper blades, including a base 1. An adjustment groove 2 is provided on the upper surface of the base 1. Symmetrically distributed sliders 4 are slidably connected to the bottom side wall of the adjustment groove 2. An arc-shaped pressing plate 5 is fixed to the top end of the slider 4, which can press and fix shafts of different sizes. One side wall of the adjustment groove 2 is rotatably connected to an adjustment shaft 3. The other end of the adjustment shaft 3 is fixed with a rotating plate 8 outside the base 1. The rotating plate 8 and the adjustment shaft 3 are perpendicular to each other. A threaded hole 7 is provided on the slider 4. A reverse thread 6 is provided on the outer wall of the adjustment shaft 3. The adjustment shaft 3 and the slider 4 are in threaded transmission connection. Symmetrically distributed guide channels are provided on the side wall of the rotating plate 8 away from the adjustment shaft 3. A guide rod 9 is slidably connected between the inner walls of the guide channels. One end of the guide rod 9 extends outside the guide channel and is jointly fixed with a pulling plate 10. The pulling plate 10 and the guide rod 9 are perpendicular to each other. A guide spring 11 is fixed between the pulling plate 10 and the rotating plate 8. Symmetrically distributed guide grooves 12 are provided on the outer wall of the base 1 along the circumferential direction. The guide grooves 12 and the guide rod 9 are in snap-fit connection, which can further fix the position of the pressing plate 5 after adjustment. Among them, the elastic force of the guide spring 11 can ensure the stable snap-fit connection between the guide rod 9 and the corresponding guide groove 12.

[0020] A positioning plate 13 is slidably connected to the upper surface of the base 1 along the circumferential direction. A positioning channel 14 penetrating left and right is formed in the positioning plate 13. A limiting plate 15 is slidably connected to the bottom side wall of the positioning channel 14. A connecting plate 16 is fixed to one side wall of the limiting plate 15. A connecting channel is formed in the outer wall of the positioning plate 13. The other end of the connecting plate 16 passes through the connecting channel. A fixing plate 17 is fixed to the outer wall of the positioning plate 13. A fixing channel is vertically formed in the upper surface of the fixing plate 17. A fixing rod 18 is slidably connected to the inner wall of the fixing channel. A connecting strip 19 is fixed above the fixing plate 17 at the top end of the fixing rod 18. The connecting strip 19 is vertically arranged with the fixing rod 18. A fixing spring 20 is fixed between the connecting strip 19 and the fixing plate 17. A plurality of parallel fixing grooves 21 are formed in the upper surface of the connecting plate 16 along its length direction. The fixing grooves 21 are in clamping fit with the fixing rod 18, which can press and fix blades of different sizes and further fix the position after fixation.

[0021] An installation plate 22 is fixed to the outer wall of the positioning plate 13. A plug rod 23 is connected to the upper surface of the installation plate 22. Symmetrically distributed slots 24 are formed in the upper surface of the base 1 along the circumferential direction. The slots 24 are in clamping fit with the plug rod 23, which can further fix the position of the adjusted positioning plate 13 and effectively adjust the welding process according to different blade angles.

[0022] The following is the working process of this solution: When welding the blade and the shaft, place the bottom of the shaft on the upper surface of the base 1, and then pull the pull plate 10. The pull plate 10 drives the guide rod 9 to move, and the guide rod 9 is separated from the guide groove 12. Then rotate the rotating plate 8, and the rotating plate 8 drives the adjusting shaft 3 to rotate. The adjusting shaft 3 drives the slider 4 to move through screw transmission. The slider 4 drives the pressing plate 5 to move, so that the two pressing plates 5 press and fix the outer wall of the shaft. Release the pull plate 10, and under the elastic force of the guide spring 11, the pressing plate 5 presses and fixes the outer wall of the shaft. Then place the blade to be welded inside the positioning channel 14. By pulling the connecting strip 19, the connecting strip 19 drives the fixing rod 18 to move, and the fixing rod 18 is separated from the fixing groove 21. Then push the connecting plate 16, and the connecting plate 16 drives the limiting plate 15 to move, so that the limiting plate 15 presses and fixes the blade. Release the connecting strip 19, and under the elastic force of the fixing spring 20, the fixing rod 18 is in clamping fit with the corresponding fixing groove 21, thereby fixing the position of the blade and making the welding position of the blade contact the outer wall of the shaft. Then perform welding. When it is necessary to adjust the position of the positioning plate 13, move the plug rod 23, push the positioning plate 13, and the positioning plate 13 drives the blade to move. Then insert the plug rod 23, and the plug rod 23 is connected and fixed with the corresponding slot 24 to complete the positioning.
