[0030] In this embodiment, one end of the coupling assembly 5 is fitted onto the support shaft 4, and the other end is fitted onto the active drill shaft 61. The coupling assembly 5 restricts the shaking during the rotation of the active drill shaft 61 driven by the motor assembly 6. Furthermore, the positional relationship between the coupling assembly 5, the motor assembly 6, and the fixed frame 1 can be steplessly adjusted through the constraint between the coupling assembly 5 and the support shaft 4.

[0031] In the embodiment, the movable sleeve 85 is installed between the first positioning sleeve 86 and the second positioning sleeve 87, the first positioning sleeve 86 and the second positioning sleeve 87 are respectively provided with positioning screws 88, that is, the first positioning sleeve 86 and the second positioning sleeve 87 are locked on the support shaft 4 through the positioning screws 88, the position relationship between the movable sleeve 85 and the support shaft 4 is limited through the first positioning sleeve 86 and the second positioning sleeve 87, and the movable sleeve 85 can rotate on the support shaft 4.

[0032] In the embodiment, the driven drill shaft 7 is respectively provided with a ball 72 and a fastening nut 74 at two ends, the drill bit 75 is installed at the bottom of the driven drill shaft 7 through the fastening nut 74, the ball 72 is installed in the ball head 71 at the top of the driven drill shaft 7 through extrusion, and the ball 72 is circular and can roll in the ball head 71.

[0033] In the embodiment, the surface of the driven drill shaft 7 is provided with uniformly arranged anti-skid lines 76, so that the friction between the driven drill shaft 7 and the rubber ball 62 is increased through the anti-skid lines 76.

[0034] In the embodiment, the variable speed disc body 8 and the arc segment shaft groove 84 are both annular in plan view, the variable speed disc body 8 is coaxial with the support shaft 4, and the arc segment shaft groove 84 is sleeved on the driving drill shaft 61, so that the variable speed disc body 8 does not interfere with the movement of the driving drill shaft 61 in the process of rotating movement.

[0035] In the embodiment, the positioning cantilever 9 is provided with a circular groove 102 at the end away from the support shaft 4, so that the spherical rubber ball 62 can sink into the positioning cantilever 9.

[0037] In use

[0038] First, the steam nozzle head 13 is arranged in the clamp 12, and under the action of the clamp 12, the steam nozzle head 13 is clamped directly below the driving drill shaft 61.

[0039] When it is needed to drill an outward expanding three-hole type hole on the steam nozzle head 13, the three-point position punching assembly 2 is adjusted to be directly below the driving drill shaft 61, at this moment, the height of the motor assembly 6 and the shaft coupling assembly 5 is adjusted, so that the rubber ball 62 below the driving drill shaft 61 is in contact with the driven drill shaft 7, and the lower end of the rubber ball 62 sinks into the groove 102 of the positioning cantilever 9.

[0040] Then the motor assembly 6 is started, and the motor assembly 6 drives the driving drill shaft 61 and the rubber ball 62 at the bottom of the driving drill shaft 61 to rotate. The rubber ball 62 drives the three driven drill shafts 7 to rotate simultaneously on the positioning swing arm in the rotating process. At this moment, the ball head 71 at the top of the positioning swing arm 9 is in contact with one end of the first speed change slope 81, and then the handle 89 is pushed to rotate the speed change disc body 8. In the rotating process, the speed change disc body 8 drives the driven drill shafts 7 to descend and ascend through the descent of the first speed change slope 81 and the ascent of the second speed change slope 83, so that the drill bits 75 at the bottom of the driven drill shafts 7 drill out three outer expansion type holes after contacting the steam nozzle head 13. In this process, the first speed change slope 81 and the second speed change slope 83 are in the shape of a spiral curve, so that the three driven drill shafts 7 do not contact the steam nozzle head 13 at the same time, thereby reducing the torque load of the motor and the rubber ball 62. At the same time, the drill bits 75 under the three driven drill shafts 7 do not contact the steam nozzle head 13 at the same time, which also reduces the concentrated generation of heat and pressure when the drill bits 75 contact the steam nozzle head 13, thereby reducing the deformation of the thin shell of the steam nozzle head 13.

[0041] When it is necessary to drill a centralized 4-hole type hole on the steam nozzle head 13, the above adjustment operation is repeated, so that a multi-point curve variable speed steam nozzle head drilling device can be used in the outer expansion type 3-hole type and the centralized 4-hole type.

[0042] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical range disclosed in the present application according to the technical solution and the inventive concept of the present application, which should be covered in the protection scope of the present application.
