The connection between the turntable 2 and the bottom plate 1 has a certain damping feeling, which can stop the rotating turntable 2 in time. A circular mounting groove 3 is provided on the upper side of the turntable 2. Vertical clamping rods 4 are provided on the front, back and both sides of the mounting groove 3. A slider 5 is installed at the lower end of each clamping rod 4. Sliding holes 6 for matching with the slider 5 are provided on the front, back and both sides of the bottom end of the mounting groove 3. The slider 5 is inside the sliding hole 6, and the outer side of the turntable 2 There is a worm gear 8 on the upper side, which is rotatably connected to the upper side of the outer side of the turntable 2. Four evenly distributed toggle holes 9 are provided on the upper side of the worm gear 8. Baffles 10 are installed on the front and rear of one side of the upper end of the turntable 2. A worm 11 is arranged between the baffles 10. The two ends of the worm 11 are rotatably connected to the sides of the baffles 10 that are close to each other. An adjusting head 21 for controlling the rotation of the worm 11 is installed on the front side of the outer side of the baffle 10. The worm 11 can drive the worm wheel 8 to rotate, but the worm wheel 8 cannot drive the worm 11 to rotate in turn, which is a unidirectional rotation characteristic.

[0020] To realize the self-positioning function of the rotation of the worm gear 8 and to position the clamping rod 4, a square top plate 12 is arranged above the bottom plate 1, and support rods 13 are installed on the front, back and both sides of the upper end of the bottom plate 1, and the top plate 12 is supported by the support rods 13, and a strip-shaped mounting hole 14 is opened in the middle position of the upper side of the top plate 12, and a moving block 15 that can slide back and forth inside the mounting hole 14 is arranged inside the mounting hole 14, and a screw rod 22 is arranged inside the mounting hole 14, and the two ends of the screw rod 22 are respectively connected to the front and back sides of the mounting hole 14 for rotation, and the moving block 15 is threadedly connected to the screw rod 22, and the moving block 15 can be driven to move back and forth inside the mounting hole 14 by the rotation of the screw rod 22, and a servo motor 23 for controlling the rotation of the screw rod 22 is installed on the rear side of the outside of the top plate 12, and a lifting cylinder 16 is installed on the lower side of the moving block 15, and a drilling rig 17 for drilling holes for the diffuser is installed at the lower end of the lifting cylinder 16.

[0021] The utility model installs limit blocks 19 on both sides of the slider 5, and both sides of the sliding hole 6 are provided with limit grooves 20 that cooperate with the limit blocks 19 to slide, so as to ensure that the clamping rod 4 can be in a vertical state when moving. The slider 5 can only move synchronously close to or away from the sliding hole 6 along the limit grooves 20 through the limit blocks 19, forming a limit structure 7. The front and back and both sides of the lower side of the bottom plate 1 are equipped with foot supports 24, and a groove wheel 25 for driving the turntable 2 to rotate is installed on the lower side of the bottom plate 1. The specific number of grooves of the groove wheel 25 can be adjusted according to the number of holes to be drilled. The bottom plate 1 is rotatably connected to a disc 26 at the rear side of the lower end, and a toggle rod 27 for toggling the groove wheel 25 is installed at the edge of the upper side of the disc 26. Through the rotation of the disc 26, the toggle rod 27 extends into the groove of the groove wheel 25. As the disc 26 rotates, the toggle rod 27 toggles the groove wheel 25. For example, the figure shows a four-groove groove wheel. The disc 26 rotates one circle and the groove wheel 25 rotates a quarter circle, which is convenient for the drill rig 17 to intermittently drill four holes in the diffuser. A driving motor 28 for driving the disc 26 to rotate is installed at the rear side of the lower end of the bottom plate 1, forming a time-differential rotation structure 18.

[0022] During the specific implementation of the utility model, the diffuser to be drilled is first placed on the upper surface of the worm wheel 8, the worm 11 is controlled to rotate by the adjusting head 21, the clamping rod 4 is adjusted by the toggle hole 9, the diffuser to be drilled is clamped by the clamping rod 4, the servo motor 23 is started, the moving block 15 is adjusted to move forward and backward, and the position of the drilling machine 17 is adjusted. After the adjustment, the turntable 2 is toggled to align the drill bit at the lower end of the drilling machine 17 with the initial position to be drilled on the diffuser, the drilling machine 17 is started, and the lifting cylinder 16 is controlled to extend, the drilling machine 17 moves downward, and the surface of the diffuser is drilled. After the drilling is completed, the cylinder drives the drilling machine 17 to move upward again, and the disc 26 drives the groove wheel 25 to rotate at this time, and the next drilling position of the diffuser is aligned with the drilling machine 17, and the lifting cylinder 16 drives the drilling machine 17 to move downward again. In this way, the reciprocating frequency of the lifting cylinder 16 extension and the speed of the disc 26 rotation can be set by the PLC program to realize automatic drilling.
