Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0022] Please refer to Figures 1 to 8 , the present utility model provides a technical solution: a ship welding positioning device, including a workbench 1, the workbench 1 is made of stainless steel material, the workbench 1 is in a regular quadrilateral shape, and support legs are welded and fixed at the four corners of the bottom of the workbench 1 to support and fix the workbench 1 through the support legs. A fixing ring is welded and fixed on the rear side wall of the workbench 1, and the fixing ring is made of iron material and is used for hanging the welding machine grounding wire during the welding process of the workpiece. An assembly groove 2 is opened in the workbench 1, and a sheet metal clamping mechanism 3 for limiting and fixing the sheet metal workpiece is assembled in the assembly groove 2. Through the sheet metal clamping mechanism 3, two sheet metal workpieces to be welded and fixed can be clamped and fixed. At the same time, a rotating shaft 4 is rotatably connected to the surface of the workbench 1, and a steel pipe limiting mechanism 5 that can adjust the height position is sleeved on the outer side wall of the rotating shaft 4. After the welding of the sheet metal workpiece is completed in the sheet metal clamping mechanism 3, the steel pipe welded to the sheet metal workpiece can be limited by the steel pipe limiting mechanism 5 to maintain the perpendicularity between the steel pipe and the steel plate during the welding process and strengthen the quality of the workpiece after the welding of the steel pipe and the steel plate is completed.
[0023] Such as Figure 2 And Figure 3As shown in the figure, the plate clamping mechanism 3 includes a first clamping table 31 and a second clamping table 32. The first clamping table 31 and the second clamping table 32 are respectively slidably connected in the assembly groove 2, and limiting blocks 33 are integrally formed on the side walls of the first clamping table 31 and the second clamping table 32. The limiting blocks 33 are slidably connected in the limiting grooves 34, and the limiting grooves 34 are opened on the side walls of the assembly groove 2. A driving motor 35 is fixedly assembled at the bottom of the workbench 1. The output end of the driving motor 35 is fixedly connected to one end of a bidirectional screw 36 through a coupling. The other end of the bidirectional screw 36 is rotatably connected to the bottom of the workbench 1. The threads in different directions of the bidirectional screw 36 are respectively screwed with the first clamping table 31 and the second clamping table 32. The driving motor 35 is electrically connected to an external power supply and an external controller. The driving motor 35 is a pulse stepping motor, and the external controller is a pulse stepping motor controller. By sending a pulse signal to the driving motor 35 through the external controller, the output end of the driving motor 35 can be controlled to drive the bidirectional screw 36 to rotate forward or backward, so as to adjust the relative position between the first clamping table 31 and the second clamping table 32.
[0024] As Figure 3 and Figure 4 shown in the figure, by rotating the rotating shaft 4, the position of the steel pipe limiting mechanism 5 can be adjusted. A limiting pin 6 inserted into the bottom of the rotating shaft 4 is fixedly assembled on the surface of the workbench 1. The relative position between the rotating shaft 4 and the workbench 1 can be fixed through the provided limiting pin 6. The number of the limiting pins 6 is two, and the two limiting pins 6 are symmetrically distributed with respect to the rotating shaft 4. By setting two limiting pins 6, the stability of limiting and fixing the rotating shaft 4 can be enhanced.
[0025] As Figure 4 shown in the figure, marking blocks 7 are respectively arranged on the side wall of the rotating shaft 4 and the surface of the workbench 1. By setting the marking blocks 7, the relative position between the rotating shaft 4 and the workbench 1 can be marked, which is convenient for the downward insertion of the limiting pin 6.
[0026] As Figure 3 、 Figure 5 and Figure 6As shown in the figure, the steel pipe limiting mechanism 5 includes an assembly ring 51, and the assembly ring 51 is sleeved on the outer side wall of the rotating shaft 4. A clamping component 8 is symmetrically assembled in the assembly ring 51. The clamping component 8 is used to fix the relative height position between the assembly ring 51 and the rotating shaft 4. A telescopic frame 9 is welded and fixed to one side wall of the assembly ring 51. The end of the telescopic frame 9 is welded and fixed with an assembly frame 52. A limiting ring 53 is clamped and fixed in the assembly frame 52. The limiting ring 53 is detachably clamped and fixed in the assembly frame 52, and the limiting ring 53 can be replaced according to the different diameters of the steel pipes to be limited. A counterweight frame 54 is welded and fixed to the other side wall of the assembly ring 51. A counterweight block 55 is clamped and fixed in the counterweight frame 54. By setting the counterweight block 55 to configure the assembly ring 51, it is avoided that the weight of the telescopic frame 9 causes the assembly ring 51 to not maintain horizontal, thereby causing the perpendicularity of the vertical limit of the steel pipe by the limiting ring 53 to deviate.
[0027] As Figure 5 shown in the figure, the clamping component 8 includes a clamping groove 81, and the clamping groove 81 is opened on the inner side wall of the assembly ring 51. An adjusting screw rod 82 is connected in the clamping groove 81 by a thread. A hand wheel 83 is welded and fixed to the outer side end of the adjusting screw rod 82. The inner side end of the adjusting screw rod 82 is rotatably connected with a clamping frame 84. A rubber pad is pasted and fixed on the inner side wall of the clamping frame 84. By setting the rubber pad, the friction force between the clamping frame 84 and the side wall of the rotating shaft 4 can be increased. A guide shaft 85 penetrating the assembly ring 51 is welded and fixed to the side wall of the clamping frame 84. By setting the guide shaft 85, the position of the clamping frame 84 can be adjusted during the process of rotating the adjusting screw rod 82, so that the clamping frame 84 abuts against the side wall of the rotating shaft 4, thereby fixing the height position of the assembly ring 51.
[0028] As Figure 6 shown in the figure, the telescopic frame 9 includes a fixed block 91, and the fixed block 91 is welded and fixed to the side wall of the assembly ring 51. A telescopic groove 92 is opened at the end of the fixed block 91. An action block 93 is slidably connected in the telescopic groove 92. The assembly frame 52 is welded and fixed to the end of the action block 93. An assembly cavity 94 is opened in the action block 93. A lifting frame 95 is assembled in the assembly cavity 94. A spring 96 is assembled between the lifting frame 95 and the assembly cavity 94. An arc body 97 is integrally formed at the top of the lifting frame 95. A rubber pad is pasted and fixed to the bottom of the arc body 97. A handle frame is welded and fixed to the top of the arc body 97. By the rubber pad at the bottom of the arc body 97 being in contact with the top of the fixed block 91, the position of the action block 93 in the telescopic groove 92 can be fixed. After pulling up the handle frame, the action block 93 can act inside the telescopic groove 92 to adjust the positions of the assembly frame 52 and the limiting ring 53. The hollow telescopic groove 92 can reduce the overall weight of the telescopic frame 9, which is convenient for improving the stability of the limiting stroke of the assembly frame 52 and the limiting ring 53.
[0029] As Figure 1As shown in the figure, a placement rack 10 is fixedly welded to the end of the workbench 1. Placement cylinders are integrally formed evenly inside the placement rack 10. By setting the placement cylinders, tools such as electrodes and welding torches required during the welding process can be placed and stored.
[0030] Working principle: As Figure 7 and Figure 8 shown in the figure, during the use of this device, there are two usage states. In the initial state (in the state shown in Figure 7 the figure), the steel pipe limiting mechanism 5 is located at the rear end of the rotating shaft 4 and will not affect the operation during the pre-welding process of plate-like workpieces. Place the plate-like workpiece between the first clamping table 31 and the second clamping table 32, and then drive the rotation of the bidirectional screw 36 through the drive motor 35 to make the first clamping table 31 and the second clamping table 32 clamp and fix the plate-like workpiece. Then, weld the plate-like workpiece on the surface of the workbench 1 with a welding torch, and the separate welding and fixing of the plate-like workpiece can be achieved;
[0031] When it is necessary to weld the welded plate-like workpiece with a steel pipe, after the welding and fixing of the plate-like workpiece are completed, rotate the rotating shaft 4 so that the steel pipe limiting mechanism 5 is located directly above the plate-like workpiece. Adjust the height of the limiting ring 53 according to the requirements of the batch-welded workpieces. The height position of the limiting ring 53 can be achieved by the fixing of the clamping component 8 inside the assembly ring 51 to the side wall of the rotating shaft 4. According to the requirements of the welding and fixing position between the steel pipe and the plate-like workpiece, adjust the position of the moving block 93 inside the telescopic groove 92, and then insert the steel pipe to be welded and fixed with the plate-like workpiece into the limiting ring 53, in the state shown in Figure 8 the figure. During the welding process between the steel pipe and the plate-like workpiece, the perpendicularity between the steel pipe and the plate-like workpiece can be maintained through the limiting ring 53. After the welding is completed, lift the limiting ring 53 upward, and then control the separation of the first clamping table 31 and the second clamping table 32, and the welded workpiece can be taken out. Then, re-clamp the limiting ring 53 into the assembly frame 52 to facilitate the subsequent batch welding.
