The drilling and locking unit 2, the nail feeder 6, the drilling and locking unit transverse drag chain 5, etc. are installed on the mobile gantry 7 and move synchronously with the gantry; the drilling and locking unit 2 has a total of 4 units, namely 1#, 2#, 3#, and 4# drilling and locking units, and each set of drilling and locking units is composed of a drilling head 21, a screw locking head 22, a drilling drive motor 23, a locking drive motor 24, a drilling down-pressing cylinder 25, and a locking down-pressing cylinder 26.

[0048] According to the different hole spacing positions of the workpiece, they can be arranged with equal spacing or unequal spacing, and can be arranged in a straight line or staggered form horizontally. This scheme adopts a 4-hole drilling and thread locking process, but it is not limited to 4 holes. The 4 sets of drilling and thread locking units in this scheme are equally spaced horizontally, and the 1#4# and 2#3# units are installed with a staggered spacing of 25 to 35mm vertically. It is suitable for workpieces with a width of about 1200mm, and the length varies in the range of 1200 to 6600mm with a module of 100mm.

[0049] During operation, the mobile workbench 9 first delivers the workpiece 8 to the working position, and then the mobile gantry 7 moves to the working position under the action of the gantry drive reducer 10 and the rack 11, and then the 1#, 2#, 3#, 4# drilling and locking wire units, the nail feeder 6 and the vacuum cleaner 12 are started at the same time. Each set of drilling and locking wire units is first driven by the drilling drive motor 23 to drive the drilling head 21 to rotate, and the drilling down-pressure cylinder 25 drives the drilling head 21 to move downward, gradually and synchronously drilling 4 through holes and countersunk holes on the workpiece 8, and the hole shape is guaranteed by the drill bit, and the dust during drilling is sucked away by the vacuum cleaner 12, and then the drilling down-pressure cylinder 25 is retracted, dragging the drilling head 21 to reset, and then the 1#, 2#, 3#, 4# drilling and locking wire units are started. The unit is synchronously translated horizontally, so that the four sets of screw locking machine heads 22 are respectively aligned with the four holes just drilled in front, and then the two sets of nail feeding machines 6 blow four self-tapping screws to the bottom of the screw locking machine heads 22 at the same time, and then the locking drive motors 24 of the four sets of drilling and thread locking units start to rotate at the same time, and the locking down cylinder 26 pushes the four screw locking machine heads 22 to press down and lock the self-tapping screws. The screws are locked in place by the torque of the locking drive motor 24.
