[0033] Working principle:

[0034] First, the electric telescopic rod 3 is lifted, and the two ends of the power distribution cabinet shell to be drilled are placed on the fixed plates 452 of the two turntables 451, and the two ends of the shell are clamped by the clamping plate 454 pushed by the air cylinder 453; then, the first motor 41 is started, and the motor drives the first screw rod 42 with bidirectional threads to rotate, and because the thread directions on the two sides of the first screw rod 42 are opposite, the two clamping seats 44 are close to each other at the top end of the base 1, and the power distribution cabinet shell is clamped; at the same time, the clamping plate 454 is pushed by the air cylinder 453 again to move towards the power distribution cabinet shell, and the cabinet shell is further clamped to ensure that the cabinet body does not move during drilling.

[0035] When it is necessary to drill different faces of the power distribution cabinet shell, the positioning pin 456 is pulled out of the limiting hole 455 on the turntable 451, the turntable 451 is manually rotated to drive the power distribution cabinet shell to rotate, and after being adjusted to a suitable processing position, the positioning pin 456 is clamped into the corresponding limiting hole 455 to complete the fixing of the cabinet body.

[0036] When the drilling tool 8 moves in the X-axis direction, the two second motors 712 are started to rotate at the same speed and in the same direction, drive the two worms 711 to rotate at the same speed and in the same direction, and make the turbine 713 meshed between the two worms 711 realize X-axis displacement movement. Since the vertical rotating rod 714 is sleeved in the turbine 713, and the first pad 715 rotatably connected to one end of the rotating rod 714 is fixedly connected to the inner wall of the protective shell 6, the X-axis direction movement of the turbine 713 drives the protective shell 6 to move in the sliding groove 5, so that the drilling tool 8 also moves in the X-axis direction.

[0037] When the drilling tool 8 needs to move in the Z-axis direction, the two second motors 712 rotate at the same speed and in opposite directions, at this time the turbine 713 realizes rotary motion between the two worms 711, the rotating rod 714 rotates with the turbine 713, the first bevel gear 721 fixedly sleeved on the outer surface of the rotating rod 714 rotates in the protective shell 6, drives the second bevel gear 722 meshed with it to rotate, and because the second bevel gear 722 is fixedly sleeved on the second screw rod 723, the rotation of the second screw rod 723 makes the sliding block 724 threaded on the surface thereof move in the displacement slot 621, and further makes the drilling tool 8 on the sliding block 724 move in the Z-axis direction.
