[0002] I-beam is a common steel structure beam. At present, in the process of building steel structure components, it is necessary to use bolts and other connecting parts to assemble I-beams together. Therefore, when producing I-beams, it is necessary to open mounting holes on the I-beams and weld corresponding accessories. In order to prevent the position of the I-beams from shifting, it is necessary to use a positioning device to fix the position of the I-beams. Most of the existing positioning devices are to set the I-beams on a workbench, and then press the I-beams through a clamping mechanism arranged on the workbench. The I-beams can be supported and positioned by the workbench. However, when using the above positioning method, when positioning I-beams of different lengths, they will be limited by the length of the workbench, which is inconvenient in use. Therefore, there are still disadvantages and shortcomings in the prior art. Utility Model Content

[0018] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1 to 5 As shown, the utility model provides a positioning device for steel structure beam production, which is used for Figure 5 The I-beam 8 shown is fixed, and the I-beam 8 includes an upper wing plate 81, a lower wing plate 82 and a web plate 83; the utility model includes a base frame 3, and when in use, the position of the base frame 3 is fixed; a vertically distributed frame structure 2 is set above the base frame 3, and two vertically oppositely distributed drive motors 4 are installed on both sides of the frame structure 2. The drive motor 4 is a forward and reverse motor, and is externally connected to a power supply and a start-stop switch; the output shaft of the drive motor 4 is coaxially sleeved with an electric telescopic rod 5, and the electric telescopic rod 5 can be set as an electric push rod, and is externally connected to a power supply and a start-stop switch, and the electric telescopic rod 5 and the drive motor 4 can share a set of power supplies; the electric telescopic rod 5 The top ends are all telescopic ends, and the telescopic ends of the electric telescopic rod 5 are all equipped with horizontally distributed clamping blocks 1 after passing through the frame structure 2 through the through holes opened on the frame structure 2. The aperture of the through holes opened on the frame structure 2 is slightly larger than the outer diameter of the electric telescopic rod 5. When in use, when the electric telescopic rod 5 is rotated under the drive of the driving motor 4, the clamping block 1 can be driven to rotate; the two ends of the clamping block 1 are not at the same distance from the axial line of the electric telescopic rod 5 in the horizontal direction, which is an eccentric clamping block. Specifically, in the initial state, the telescopic end of the electric telescopic rod 5 is in an extended state, and the end of the clamping block 1 farther from the electric telescopic rod 5 is located on the outside of the frame structure 2.

[0020] When in use, the number of positioning devices of the utility model is at least two groups and they are arranged opposite to each other. Then, the lifting equipment can be used to place the I-beam 8 horizontally on the top surfaces of several frame structures 2. At this time, the two clamping blocks 1 on each frame structure 2 will be respectively located outside the two sides of the I-beam 8, and then the electric telescopic rod 5 can be driven by the driving motor 4 to rotate so that the end of the clamping block 1 farther from the electric telescopic rod 5 is rotated to the top of the lower wing plate 82 of the I-beam 8. Then, when the telescopic end of the electric telescopic rod 5 is retracted, the clamping block 1 can be pressed and fixed to the I-beam 8 to prevent the position of the I-beam 8 from shifting. When positioning I-beams 8 of different lengths, different numbers of positioning devices can be set according to the different lengths of the I-beams 8 to stably support the I-beam 8, thereby facilitating the positioning of I-beams 8 of different lengths.

[0021] Further, such as Figure 1 , Figure 3 and Figure 5 As shown, a limiting groove 21 which horizontally penetrates the frame structure 2 is provided on the frame structure 2 located between the two electric telescopic rods 5, and the top surface of the limiting groove 21 is flush with the top surface of the frame structure 2. Specifically, the two electric telescopic rods 5 are symmetrically distributed on both sides of the limiting groove 21, and when the end of the clamping block 1 which is farther from the electric telescopic rod 5 is located on the outside of the frame structure 2, the clamping block 1 is completely located outside the limiting groove 21; in addition, the size of the limiting groove 21 is adapted to the width of the lower wing plate 82, and the groove depth of the limiting groove 21 is less than the thickness of the lower wing plate 82, so that when in use, the limiting groove 21 can be used to facilitate the placement of the I-beam 8 at a suitable position on the frame structure 2, so that the I-beam 8 can be subsequently clamped and fixed by the clamping block 1.

[0022] Further, such as Figure 1 , Figure 3 and Figure 5As shown, the bottom frame 3 includes a horizontally arranged bottom plate 31, and when in use, the position of the bottom plate 31 is fixed; a top plate 32 arranged parallel to the bottom plate 31 is installed above the bottom plate 31, and vertically distributed legs 33 are installed between the two sides of the top plate 32 and the bottom plate 31, and the four corners of the top surface of the top plate 32 are fixedly connected with vertically relatively distributed guide rods 7, the frame structure 2 is located above the top plate 32, and the two sides of the bottom of the frame structure 2 extend outwardly to form fixed blocks 22, and each fixed block 22 is slidably sleeved on the two guide rods 7 located on the same side of the top plate 32, so that the frame structure 2 can be The frame structure 2 slides slightly along the guide rod 7 to adjust the height position of the frame structure 2; and the top plate 32 is also threadedly connected to a threaded rod 6 that vertically penetrates the top plate 32 and is located below the frame structure 2. A hand wheel 12 is installed at the bottom end of the threaded rod 6. The hand wheel 12 can facilitate the rotation of the threaded rod 6. Specifically, after adjusting the height position of the frame structure 2, the top end of the threaded rod 6 can be abutted against the frame structure 2 by rotating the threaded rod 6 to support the frame structure 2; and since the height of the frame structure 2 can be adjusted, it can be adapted to production personnel of different heights.

[0023] Further, such as Figures 1 to 5 As shown, a locking sleeve 9 is slidably sleeved on the guide rod 7 located above the fixed block 22, and a locking screw 10 penetrating the locking sleeve 9 is threadedly connected to the locking sleeve 9, and the locking screw 10 is parallel to the radial direction of the locking sleeve 9. Specifically, during use, when the locking screw 10 is not pressed against the guide rod 7, the locking sleeve 9 can be slid along the guide rod 7 during the process of adjusting the height position of the frame structure 2, and then after the height position of the frame structure 2 is adjusted into place and the top end of the threaded rod 6 is in contact with the frame structure 2, the locking sleeve 9 can be first pressed against the fixed block 22, and then the locking screw 10 can be rotated to press the locking screw 10 against the guide rod 7, so that the position of the frame structure 2 can be fixed to stably support the frame structure 2.
