[0024] like Figure 1-2As shown, a steel frame chamfering clamping tool provided in this embodiment includes: a base 1; a first drive assembly 2, the first drive assembly 2 is connected to the base 1, and the first drive assembly 2 can drive the base 1 to rotate; a fixed clamp 3, the fixed clamp 3 is arranged on a placement plate 7; a movable clamp 5, the movable clamp 5 is slidably connected to the placement plate 7, and an I-beam clamping area is formed between the movable clamp 5 and the fixed clamp 3; a placement plate 7, the placement plate 7 is fixed on the base 1; a second drive assembly 6, the second drive assembly 6 is connected to the movable clamp 5, and the second drive assembly 6 is used to drive the movable clamp 5 to move closer to or away from the fixed clamp 3. The fixed clamp 3 and the movable clamp 5 are both flat plate structures. The first drive assembly 2 includes a first drive member 22 and a first transmission member, the first drive member 22 is connected to the first transmission member, and the first transmission member is connected to the base 1. The second drive assembly 6 includes a second drive member 61 and a second transmission member, the second drive member 61 is connected to the second transmission member, and the second transmission member is fixedly connected to the movable clamp 5. Specifically, the first driving member 22 and the second driving member 61 are both existing rotating motors, the first transmission member is the roller 21 , the base 1 is an arc-shaped plate, and the roller 21 and the base 1 are frictionally transmitted. Among them, the number of the first driving member 22 and the first transmission member are both two, and the two first driving members 22 are respectively connected to the first transmission member for transmission, and the two first transmission members are arranged at intervals. For example, the two rollers 21 are in contact and friction with the arc plate, and the two rollers 21 are distributed at intervals in the same horizontal plane. Exemplarily, the first driving member 22 is an existing rotating motor, and the output shaft of the rotating motor rotates to drive the roller 21 to rub against the base 1, thereby driving the base 1 to rotate; the second transmission member includes a screw 62 and a sliding seat 63, the second driving member 61 and the screw 62 are both located at the bottom of the placement plate 7, the second driving member 61 is fixed at the bottom of the placement plate 7, the output shaft of the second driving member 61 is fixedly connected to the screw 62, the screw 62 is rotationally connected to the placement plate 7, the placement plate 7 is provided with a slide groove, the sliding seat 63 is threadedly connected to the screw 62, and the sliding seat 63 is fixedly connected to the movable clamp 5 through the slide groove. Specifically, the lead screw 62 is connected by two lead screw seats, and the two lead screw seats are fixed at the bottom of the placement plate 7. The lead screw seats are provided with rotation holes to facilitate the rotation of the lead screw 62 relative to the lead screw seats.

[0025] The principle is as follows: when in use, first put the steel frame (I-beam 4) from the opening of the arc plate onto the placement plate 7, specifically the I-beam clamping area between the movable clamp 5 and the fixed clamp 3, and then start the second driving member 61 to drive the screw 62 to rotate, the screw 62 rotates to make the sliding seat 63 slide along the axial direction of the screw 62, that is, slide in the slide groove, and the movable clamp 5 approaches the direction of the fixed clamp 3 until the movable clamp 5 and the fixed clamp 3 respectively press the two sides of the I-beam 4, completing the clamping of the I-beam 4; first use the chamfering machine to The end of the I-beam 4 is chamfered. After a part of the end of the I-beam 4 is chamfered (for example, the part away from the placement plate 7 has been chamfered), the chamfering is stopped, and the roller 21 is driven to rotate by the two first driving members 22. The roller 21 rotates and contacts and rubs with the outer surface of the arc plate. The arc plate is rotated through friction transmission to adjust the chamfered position of the I-beam 4, which is convenient for workers to chamfer the part close to the placement plate 7 until all the edges of the end of the I-beam 4 are chamfered; the chamfering process of one I-beam 4 is completed. Through the cooperation of the movable clamp 5 and the fixed clamp 3, the I-beams 4 of different sizes can be clamped, and the base 1 is driven to rotate by the first driving assembly 2, which is convenient for workers to chamfer the ends of the I-beam 4 in all directions.

[0026] In some embodiments, the first transmission member is a gear, the base 1 is an arc-shaped plate, a rack is provided on the base 1, the gear is fixedly connected to the output shaft of the first driving member 22, and the gear is meshed with the rack. Considering that the first transmission member adopts the roller 21 friction transmission mode, the roller 21 and the base 1 are easy to wear. When worn to a certain extent, the friction between the roller 21 and the base 1 is reduced, and slipping may occur. Therefore, by providing a rack (the rack is distributed in an arc shape) at the edge of the arc-shaped plate, the arc-shaped plate is driven to rotate by the gear and rack, so as to overcome the friction transmission easy to wear and reduce the friction and cause slipping.
