[0030] See also Figure 1 The present invention provides a technical solution: a rudder blade drilling device, comprising a body 1, on which a drilling mechanism 2 and a clamping mechanism 3 are sequentially arranged, the drilling mechanism 2 comprising a rotating motor 21 and a mounting frame 22, the mounting frame 22 is provided with a fixing flange 221, the mounting frame 22 is respectively equipped with a detachable and replaceable grinding component 4 and a drill bit component 5, when the drill bit component 5 completes the drilling of the rudder blade, it can be removed and replaced by the grinding component 4 and installed on the mounting frame 22, so as to grind the holes in the rudder blade.

[0031] In this embodiment, the drill assembly 5 includes a first rotating disk 51, and a first connecting flange 512 is provided on the periphery of the first rotating disk 51. Since the first connecting flange 512 matches the fixing flange 221, when the first connecting flange 512 and the fixing flange 221 are aligned close to each other, the first rotating shaft interface 511 provided on one side of the first rotating disk 51 will be connected to the rotating shaft 211 on the rotating motor 21, and then the aligned first connecting flange 512 and the fixing flange 221 are directly fixed by bolts, so that the drill assembly can be fixed on the mounting frame. After fixing, the drill 52 provided on the other side of the first rotating disk 51 corresponds to the clamping mechanism 3.

[0032] When the rotating motor is started, the first rotating disk is driven to rotate, thereby driving the drilling hole to rotate.

[0033] In this embodiment, the grinding assembly 4 includes an inner disc 41, and a second rotating disc 42 is provided on one side of the inner disc 41. The second rotating disc can rotate on the inner disc, and a second rotating shaft interface 421 is provided on the second rotating disc 42 for connecting with the rotating shaft 211 on the rotating motor 21.

[0034] A first movable groove 411 is provided on an outer wall of the inner disk 41, an outer ring 43 is provided on the periphery of the inner disk 41, a second movable groove 431 is provided on an inner wall of the outer ring 43, a movable ring 44 is clamped between the first movable groove 411 and the second movable groove 431, and the movable groove can rotate between the inner disk and the outer ring.

[0035] A connecting rod 441 is provided on one side of the movable ring 44, and the connecting rod 441 is connected to the second rotating disk 42. When the second rotating disk rotates, the movable ring is driven to rotate together. At this time, a grinding rod 45 is provided on the other side of the movable ring 44, and it also moves in a circle along the track of the movable ring.

[0036] A second connecting flange 432 is arranged on the periphery of the outer ring 43, and the second connecting flange 432 is also matched with the fixed flange 221. When the second connecting flange and the fixed flange 221 are aligned closely, the second rotating shaft interface on the second rotating disk will be connected with the rotating shaft 211 on the rotating motor 21, and then the aligned second connecting flange and the fixed flange 221 are fixed by bolts, so that the grinding assembly can be fixed on the mounting frame.

[0037] In this embodiment, the clamping mechanism 3 includes a base 31, and a roller 311 is provided at the bottom of the base 31. The roller 311 is arranged on a slide rail 11, and the slide rail 11 is transversely arranged on the body 1. Such a structural design enables the base to slide and move on the slide rail.

[0038] Support frames 312 are arranged on both sides of the base 31, and the rear side of each support frame 312 is connected to an electric push rod 32. When the electric push rod is started, the base can be pushed to move on the slide rail.

[0039] A support plate 33 is provided between the support frames 312 on both sides, and a through hole 331 is provided on the support plate 33 for inserting the rudder. When the rudder passes through the through hole, the magnetic sheet 332 provided on the support plate 33 will be attracted to the edge of the rudder. Since the through hole 331 corresponds to the base 31, the bottom of the rudder will fall onto the base.

[0040] A set of corresponding clamps 34 are arranged on the support frames 312 on both sides to clamp the rudder blade. The clamps 34 include an arc-shaped clamp 341 that fits the rudder blade, a push rod 342 is arranged on the arc-shaped clamp 341, and a rotating handle 343 is arranged on one end of the push rod 342 that passes through the support frame 312. When the rotating handles on both sides are tightened at the same time, the push rods on both sides push the arc-shaped clamp to clamp the rudder blade.

[0041] A water spray head 35 is also provided on the support plate 33 at the front end of the through hole 331. The water spray head 35 is arranged downward. The water spray head 35 is connected to a water inlet pipe 351 for conveying water to the water spray head for spraying. The sprayed water is used for cooling during drilling and grinding.

[0042] In this embodiment, the drill bit 52 comprises a drill rod 521, and a positioning drill bit 522 is provided at the end of the drill rod 521 for positioning drilling of the part of the rudder blade to be drilled. Then, a group of first reaming knives 523 are provided on the drill rod 521 located on both sides of the positioning drill bit 522 to expand the drill hole, mainly through the reaming blade 5231 provided on the side of the first reaming knife 523 and the planing blade 5232 provided on the side of the first reaming knife 523 adjacent to the positioning drill bit 522 to expand the hole.

[0043] A set of second reaming knives 524 is arranged on the drill rod at the upper end of the first reaming knives 523. The diameter of the second reaming knives 523 is larger than that of the first reaming knives 524, and can be used to further expand the drilled hole. The second reaming knives 524 have the same structure as the first reaming knives 523, so they also expand the hole by reaming blades and planing blades;

[0044] In the above embodiment, after the positioning drill bit 522 is positioned, as the rudder blade is pushed forward, the first reaming knife and the second reaming knife gradually expand the hole surface from a small surface to a large surface. In this way, after the torque increases, the contact surface of the drill bit also increases, which can effectively increase the strength of the drill bit.

[0045] Working principle: First, fix the rudder piece on the clamping assembly, then install the drilling mechanism 2 on the mounting frame, then start the electric push rod to drive the rudder piece close to the drill bit, turn on the rotary motor to drive the drill bit to rotate for drilling, during which the water spray head on the clamping assembly will continuously spray water downwards;

[0046] After drilling is completed, turn off the rotating motor, replace the drilling mechanism with a grinding mechanism, and then start the electric push rod to drive the rudder blade close to the grinding rod. After the grinding rod enters the drill hole, turn on the rotating motor to drive the grinding rod to rotate. At this time, the grinding rod is polished along the inner wall of the drill hole, and the water spray head on the clamping assembly will continuously spray water downwards;

[0047] After grinding is completed, the rotating motor can be turned off and the processed rudder blade can be removed from the clamping mechanism.
