[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] Embodiment 1, by Figure 1 The utility model includes a power head assembly 1 installed with a lifting device, a bottom plate 2 is provided below the power head assembly 1, an upper end of the bottom plate 2 is connected to a panel 3, the panel 3 is arranged in an L-shaped structure, an upper end of the panel 3 is connected to a drilling template 4, an upper end of the drilling template 4 is provided with a workpiece hole, a drilling template sleeve 5 is embedded inside the workpiece hole, a steel pipe workpiece is located in a space formed by the drilling template 4 and the panel 3, a clamping cylinder 6 is installed on one side of the upper end of the bottom plate 2, and an output end of the clamping cylinder 6 is connected to a fixing plate 7;

[0015] Specifically, the power head assembly 1 includes a power clamp 8 installed with the lifting device, the lower end of the power clamp 8 is installed on the gear box 9, the output end of the gear box 9 is connected to a drill clamp 10, the lower end of the drill clamp 10 is installed with a drill bit 11, and the drill bit 11 corresponds to the drill template sleeve 5;

[0016] The drilling jig sleeve 5 can guide and position the drill bit 11, thereby ensuring the hole processing accuracy.

[0017] Working principle: When in use, first place the steel pipe workpiece to be processed in the space formed by the drilling template 4 and the enclosure 3, and then use the clamping cylinder 6 to drive the fixed plate 7 to hold the steel pipe workpiece for a fixed processing distance. After confirming that the clamping is adjusted, the power head assembly 1 is gradually lowered by the lifting device, and at the same time, the gear box 9 drives the drill bit 11 to rotate. When the drill bit 11 drops to the distance set by the microcomputer (PLC) in the electric box, the power head assembly 1 stops rotating and is driven by the lifting device to return to the starting point. When all machines stop running, the clamping cylinder 6 drives the fixed plate 7 to release the clamped steel pipe workpiece and take out the processed workpiece, and this processing is completed.
