[0038] The spiral ridge 82 is engaged with one of the spiral grooves 31, specifically, one side of the spiral ridge 82 is engaged with the upper edge of the spiral groove 31; and the spiral ridge 82 is engaged with the other spiral groove 31, specifically, one side of the spiral ridge 83 is engaged with the lower edge of the spiral groove 31; by engaging the spiral ridge 82 with one of the spiral grooves 31, and by engaging the spiral ridge 83 with the other spiral groove 31, the elastic sleeve 8 is facilitated to engage with the limiting sleeve 3.

[0039] The detachable sleeve 4 is composed of three arc-shaped plates 41 evenly distributed around the circumference.

[0040] Since the detachable sleeve 4 is composed of multiple parts, and each part is detachable; and the elastic sleeve 8 is spliced by two arc-shaped sleeves 81, it is convenient for the elastic sleeve 8 to cooperate with the limiting sleeve 3; when the elastic sleeve 8 is matched with the limiting sleeve 3, except for the part of the arc-shaped sleeve 81 corresponding to the three spiral grooves 31 (this part includes the spiral protrusion 1 821 and the spiral protrusion 2 831), the other parts of the arc-shaped sleeve 81 fit the outer wall of the limiting sleeve 3.

[0041] The air guide assembly 7 includes three air nozzles 74, which penetrate the middle position of the three arc-shaped plates 41 respectively.

[0042] A guide bucket 62 is also fixedly provided on the movable frame 6.

There is a gap between the tapping head 21 and the bottom end of the guide bucket 62.

[0043] In this embodiment, by placing the metal plate on the support platform 11, the metal plate can be fixed or adjusted in conjunction with the existing clamping device. This is the existing technology and will not be described in detail. By driving the fixed column 2 to rotate by the second drive motor 611, the tapping head 21 can be driven to rotate, and at the same time, the moving frame 6 can be driven to descend in conjunction with the moving component 5 to perform tapping operations on the metal plate.

[0044] In this embodiment, a spiral groove 31 is provided on the limiting sleeve 3, so that the elastic sleeve 8 is conveniently matched with the limiting sleeve 3; at the same time, during the tapping process, an air flow is introduced into the air guide tube 71 through an external pressure air source, and the air flow is further introduced into the three air nozzles 74 through the air guide hose 73, and the three air nozzles 74 spray pressure air flows into the three spiral grooves 31 respectively; since the three air nozzles 74 are respectively located in the middle of the three arc plates 41, the three arc plates 41 are evenly distributed along the circumference of the axis of the limiting sleeve 3, that is, pressure air flows into different spiral grooves 31 from multiple directions, and the air flow inside each spiral groove 31 flows along the spiral groove 31, that is, three spiral air flows are formed outside the limiting sleeve 3, and each pressure air flow They are all covered on the outside of the limiting sleeve 3; due to the covering effect of the airflow, the limiting sleeve 3 is helped to maintain stability; at the same time, since the elastic sleeve 8 and the limiting sleeve 3 are matched, that is, a part of the elastic sleeve 8 is matched on the outside of the limiting sleeve 3, and the spiral ridge 1 82 and the spiral ridge 2 83 are respectively matched in the two spiral grooves 31; when the limiting sleeve 3 vibrates horizontally or vertically, the elastic sleeve 8 can slow down the vibration, thereby effectively ensuring the stability of the limiting sleeve 3 and reducing the shaking and deviation of the limiting sleeve 3; since the stability of the limiting sleeve 3 is guaranteed, it is further convenient to ensure the stability of the fixing column 2, thereby improving the stability of the tapping head 21, that is, it can slow down the vibration of the tapping head 21 and reduce the deviation of the tapping head 21, which helps to ensure the tapping quality.

[0045] At the same time, the air flow in the spiral groove 31 is discharged from its bottom end into the guide bucket 62, and the air flow is discharged downward through the guide bucket 62. The air flow flows around the tapping head 21, thereby having a cooling effect on the tapping head 21. When the external pressure air source is a cold flow, the cooling effect on the tapping head 21 can be improved, reducing or avoiding the reduction in tapping accuracy due to the heating of the tapping head 21.

[0049] In this embodiment, the first drive motor 51 drives the screw rod 52 to rotate, which can further drive the movable frame 6 to move up and down, thereby driving the tapping head 21 to descend for tapping operation. At the same time, after the tapping is completed, the tapping head 21, the movable frame 6, etc. can be driven to reset.
