[0037] Preferably, in this embodiment, the first vertical moving assembly 15 and the second linear moving assembly 27 both use electric push rods;

[0038] Preferably, the posture monitoring sensor includes three displacement sensors and one angle grating sensor, which are installed on the movable ends of the first vertical moving component 15, the X-axis linear moving component 14 and the Y-axis linear moving component 5.

[0043] The auxiliary limiting assembly includes a support frame 16, and the support frame 16 includes two cross bars and a vertical bar. The two ends of the vertical bar are respectively fixed to one end of the cross bar, and the other end of the lower cross bar of the support frame 16 is fixed to the movable end of the Y-axis linear moving assembly 5.

[0044] A pressure sensor is provided on the inner side of each clamping roller 17, and the pressure sensor is electrically connected to the main controller. The pressure sensor communicates with the main controller through a transmission module. The pressure sensor monitors the pressure felt by the clamping roller 17 when clamping the workpiece in real time. When the pressure exceeds the set threshold, the pressure is fed back to the main controller. The main controller controls the retraction of the telescopic rod of the double-headed telescopic rod 24 to reduce the clamping force and avoid damage to the workpiece surface.

[0045] In this embodiment, the auxiliary limit assembly can limit the two sides of the workpiece where the hole needs to be drilled. The main controller can drive the round shaft 22 to move by controlling the extension and retraction of the double-headed telescopic rod 24. The round shaft 22 drives the moving block 21 to move. The moving block 21 drives the swing rod 30 to swing. The swing rod 30 drives the clamping roller 17 to move, thereby realizing the mutual separation and approach between the two pairs of clamping rollers 17 at both ends.

[0049] In this embodiment, both the lateral linear moving component 4 and the vertical moving component 6 adopt existing products including existing linear rails and drive components. This is the prior art and will not be described in detail. The specific structure of the drive component is not shown in the drawings.

[0050] A main controller, the main controller electrical signal connects the lateral linear moving component 4, the vertical moving component 6, the motor cavity 7, the first stepper motor 13, the first vertical moving component 15 and the second linear moving component 27.

[0051] In this embodiment, an auxiliary tightening assembly is provided to assist in tightening the other end of the workpiece.

The position of the cylinder 3 and the tightening block 31 can be adjusted by the lateral linear moving assembly 4 and the vertical moving assembly 6 respectively, so that the tightening block 31 is aligned with the other end of the workpiece.

[0052] When in use, one end of the workpiece is fixed by the clamp 101. If necessary, the auxiliary clamping assembly is used to support the other end of the workpiece through the clamping block 31. The position of the electric drill 29 is adjusted by the electric drill position adjustment module of the drilling assembly to align it with the position where the hole needs to be drilled and the correct angle. The auxiliary limit assembly is used to auxiliary clamp and fix the workpiece around the hole where the hole needs to be drilled. The main controller controls the electric drill 29 to start drilling. During the drilling process, through a pre-set program, the controller controls the first stepper motor 13 to drive the active end of the X-axis linear moving assembly 14 to move toward the workpiece, driving the electric drill 29 to continuously feed the hole. During the drilling process, the current sensor monitors the real-time current of the electric drill 29 and sends the signal to the A / D converter. The A / D converter receives the current analog signal and converts it into a digital signal and sends it to the main controller. The three displacement sensors can respectively measure the active positions of the first vertical moving assembly 15, the X-axis linear moving assembly 14 and the Y-axis linear moving assembly 5. The linear displacement of the moving end, the angle grating sensor is used to measure the angle of the drill bit of the electric drill 29, so as to determine the real-time position and posture information of the drill bit. The PID control unit in the main controller is compared with the set value. When the drill bit is worn or the angle deviates slightly, the current becomes smaller accordingly. The main controller controls the angle adjustment of the drill bit of the electric drill 29 by controlling the extension and retraction of the movable ends of the first vertical moving component 15 and the second linear moving component 27, so as to achieve angle compensation when the electric drill 29 is drilling, improve the drilling accuracy, make the current of the electric drill 29 constant within the current value range set by the built-in program of the main controller, keep the angular position of the drill bit of the electric drill 29 and the surface of the product to be processed constant, and make the drilling accuracy higher. The displacement sensor installed at the movable end of the X-axis linear moving component 14 monitors the feed depth. When the drilling depth is appropriate, the main controller controls the first stepper motor 13 to rotate in the opposite direction to drive the drill bit of the electric drill 29 to move out of the workpiece. After the drilling is completed, the workpiece is released and can be taken away.

[0053] The present invention can monitor the posture and current changes of the electric drill in real time through the drill bit posture compensation component. The main controller adjusts the position of the electric drill according to the monitoring data to achieve angle compensation and depth control in the drilling process.
