For steel pipe trusses of different structures, the center angles corresponding to the structural center lines of the actually used circular-arc main support steel pipes are different, and the radius sizes corresponding to the structural center lines are different, so that before clamping the circular-arc main support steel pipes in the machining process, operations of step S1 and step S2, namely operations of radius adjustment and opening angle opening, need to be performed;

in the process of adjusting the radius in step S1, specifically, the two clamping mechanisms 3 are sequentially and respectively slid along the channel steel 25 to adjust the radius distance between the two clamping mechanisms 3 and the hinge center of the hinge rotating seat 11, and the radius distances of the two clamping mechanisms 3 after adjustment are ensured to be substantially equal, so that the adjusted radius distance is adapted to the radius size of the actually processed main support steel pipe, and the main support steel pipe is conveniently placed between the clamping blocks 322 in the two pairs of pipe wall clamping assemblies 32 in the clamping mechanisms 3; in the process of adjusting the flare angle in step S2, specifically, the handwheel screw 22 is rotated to drive the swivel nut articulated seat 23 to move, and then the swivel nut articulated seat 23 drives the two rotating rods 24 to rotate along the rotating guide ring 21 through the connecting rod 26, so as to open the flare angle of the two rotating rods 24, and the two corresponding clamping mechanisms 3 synchronously move along with the rotating rods 24, so that the distance between the two side stopper clamping assemblies 33 in the circumferential direction is opened, and the main support steel pipe to be processed is conveniently placed between the two side stopper clamping assemblies 33;

It should be noted that the electric turntable 41 may be selected from a commercial electric turntable 41, and the electric turntable 41 may precisely control the rotation angle.

When the drilling angle is adjusted in step S7, the electric turntable 41 rotates the rotary wall, so as to rotate the drilling machine 63 randomly, and then the drilling angle position of the drilling machine 63 is adjusted, so as to complete the drilling operation for all holes after multiple adjustments.

The lifting adjusting mechanism 5 is mainly used for completing the operation of adjusting the drilling height in the step S6, because the actual diameter sizes of the main supporting steel pipes are different, after the main supporting steel pipes are placed and tightened, the heights of the structural center lines of the main supporting steel pipes are slightly different, so that the lifting cylinder 52 drives the lifting vertical plate 53 to vertically lift along the guide frame 51, the height of the drilling machine 63 is driven to be adjusted, the position of the drilling machine 63 facing the center line of the main supporting steel pipe is ensured, and the deviation of drilling holes is prevented.

When the side clamping operation of step S4 is performed, during the process of turning the hand wheel screw 22 to decrease the opening angle, on one hand, after the side end of the main support steel pipe contacts the side baffle portion 3323, the side end surface of the main support steel pipe will actively abut against the side wall of the side baffle portion 3323, thereby pushing the side baffle portion 3323 to turn around the hinge position toward the side of the slot block portion 3322, as it turns, the side end of the main support steel pipe will completely abut against the side baffle portion 3323, the arc spring 3325 will be lengthened, the arc spring 3325 will provide the clamping force of the side baffle portion 3323 against the steel pipe, on the other hand, as it is clamped, the sliding plate portion 3321 will slide outward along the guide rod 331, the linear spring will be lengthened, the linear spring will also provide the clamping force, and therefore the main support steel pipe will be effectively clamped at the side end.

Furthermore, the hinged rotating seat 11 is provided with a rotation angle scale ring 111 for indicating the rotation adjustment angle of the drill angle adjusting assembly 4. The angle of the drill hole can be visually observed in real time by the angle scale ring 111.
