[0025] Embodiment 1

[0026] like Figure 4-5As shown, in the present embodiment, the clamping mechanism 300 comprises two sliders 1 310, the interior of one slider 1 310 is slidably connected to the outer wall of the round rod 1 130, the interior of the other slider 1 310 is screwed together with the outer wall of the single screw rod 121, the top surfaces of the two sliders 1 310 are fixedly connected with a strip plate 320, the top surface of the strip plate 320 is symmetrically fixed with two baffles 321, a double screw rod 331 is rotatably connected between the two baffles 321, the top surface of the strip plate 320 is fixedly connected with a motor 330, the motor shaft of the motor 330 is transmission-connected to one end of the double screw rod 331, the outer wall of the double screw rod 331 is symmetrically screwed together with two fitting units 350, the fitting unit 350 comprises a slider 2 351, the interior of the slider 2 351 is screwed together with the outer wall of the double screw rod 331, the interior of the slider 2 351 is slidably plugged with two round rods 2 322, the two round rods 2 The two ends of 322 are respectively fixedly connected to the inner side walls of the two baffles 321, and the top surface of the slider 351 is fixedly connected with a clamping plate 352. A number of insertion holes 353 are equidistantly provided inside the clamping plate 352, and a number of ball head bosses 354 are slidably inserted in the number of insertion holes 353. Reset springs 355 are provided in the number of insertion holes 353. One end of the reset spring 355 is fixedly connected to the inner wall of the clamping plate 352, and the other end of the reset spring 355 is fixedly connected to the end of the ball head boss 354. The arc-shaped ends of the number of ball head bosses 354 are provided with anti-slip grooves. The left and right threads of the double screw rod 331 are opposite in rotation direction. The outer wall of the double screw rod 331 is located in the middle position to sleeve and fix a limit ring. A bracket 340 is provided at the position above the strip plate 320 corresponding to the limit ring, and the two inner side walls of the bracket 340 are respectively fixedly connected to the left and right side walls of the strip plate 320.

[0027] In this embodiment, since the left and right threads of the double screw rod 331 are in opposite directions, the motor shaft of the drive motor three 330 is driven clockwise to the double screw rod 331, and the two fitting units 350 will move in opposite directions, and the special-shaped welded pipe to be drilled is placed on the bracket 340, and the motor shaft of the drive motor three 330 is driven counterclockwise to the double screw rod 331, and the two fitting units 350 will move in opposite directions, so that a plurality of ball head bosses 354 are close to the outer wall of the welded pipe. Since the ball head boss 354 and the clamping plate 352 are internally slidably connected, and the end of the ball head boss 354 inside the plug hole 353 is fixedly connected with a return spring 355. When the end of the ball head boss 354 contacts the outer wall of the welded pipe, the plurality of ball head bosses 354 will shrink into the plug hole 353 under the pressure of the outer wall of the welded pipe until the ends of the plurality of plug holes 353 are in contact with the outer wall of the special-shaped welded pipe and then the slider 310 stops. At this time, the plurality of ball head bosses 354 will be closer to the outer wall of the special-shaped welded pipe under the elastic force of the reset spring 355. At the same time, the anti-slip texture of the arc-shaped end of the ball head boss 354 increases the friction between the ball head boss 354 and the outer wall of the special-shaped welded pipe, so that the device is not prone to angle deviation when drilling the special-shaped welded pipe.
