[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.
[0022] like Figure 1-4 As shown, a steel frame cutting, marking and positioning device includes a base plate 1, one end of the upper side of the base plate 1 is fixedly connected to a top plate 2, the rear side of the top plate 2 is fixedly connected to a rotating rod 3, the outer side of the rotating rod 3 is rotatably connected to a rocker arm 4, the end of the rocker arm 4 away from the rotating rod 3 is fixedly connected to a guide plate 5, the outer side of the guide plate 5 is equipped with a movable guide rail 9, the guide rail 9 is slidably connected to a slide bar 10, and one end of the slide bar 10 is equipped with a marking pen 14. At this time, by moving the guide rail 9 on the guide plate 5, the distance between the marking pen 14 and the rocker arm 4 is adjusted so that the distance between the marking pen 14 and the rocker arm 4 is the same as the set length of the I-beam 15, the rocker arm 4 can be rotated to allow the marking pen 14 to move around the I-beam 15, so that a complete circle of positioning lines can be drawn around the I-beam 15.
[0023] like Figure 2-4As shown, the outer side of the guide plate 5 is slidably connected to a sliding ring 6, and the guide rail 9 is fixedly connected to the outer side of the sliding ring 6. At this time, the distance between the guide rail 9 and the top plate 2 can be adjusted by sliding the sliding ring 6, and a first locking screw 7 is threadedly connected to the sliding ring 6. The position of the sliding ring 6 on the guide plate 5 can be locked by the first locking screw 7, and the adjustment method is relatively simple.
[0024] like Figure 1-2 As shown, a scale 8 is provided on one side of the guide plate 5 . The scale 8 allows the user to determine the distance between the marking pen 14 and the top plate 2 more easily.
[0025] Among them, such as Figure 4 As shown, the material of the slider 10 is iron, and a magnetic strip 16 is fixedly connected to the inside of the guide rail 9. The magnetic strip 16 is a strip structure fixedly connected to the inside of the guide rail 9 along the axial direction of the guide rail 9. After the slider 10 slides, the magnetic strip 16 can be used to magnetically adsorb and position the slider 10 to reduce the shaking of the slider 10.
[0026] like Figure 4 As shown, in order to install different types of marking pens 14, a sleeve 12 is assembled at one end of the slide 10, and the marking pen 14 is inserted into the inside of the sleeve 12, and a second locking screw 13 is threadedly connected to the sleeve 12, and the marking pen 14 can be locked by the second locking screw 13.
[0027] At the same time, one end of the slide 10 is fixedly connected to the connecting frame 11, and the outer side of the sleeve 12 is fixedly connected to a round rod, which is rotatably connected to the connecting frame 11. At this time, through the rotation of the sleeve 12 on the connecting frame 11, the marking pen 14 can better fit the inner wall of the recessed area on both sides of the I-beam 15, reducing the dead angle of marking, so that a more complete circle of positioning lines can be drawn around the I-beam 15.
[0028] The working principle of this utility model is:
[0029] Place the I-beam 15 on the upper side of the base plate 1, and make one end of the I-beam 15 abut against the top plate 2. By moving the guide rail 9 on the guide plate 5, adjust the distance between the marking pen 14 and the rocker arm 4 so that the distance between the marking pen 14 and the rocker arm 4 is the same as the set length of the I-beam 15. Then, rotate the rocker arm 4 to move the marking pen 14 around the I-beam 15. After the exposed side of the I-beam 15 is marked, turn the I-beam 15 over and mark the remaining side, so that a complete circle of positioning lines can be drawn around the I-beam 15.
[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
