Under the action of the fourth elastic piece 144, the front end of the locking head 141 is located in the locking hole 122, so that the support plate seat 12 is locked and the support plate seat 12 cannot descend. A support plate 121 is provided on the support plate seat 12.

[0023] The Y-axis 22 is provided with an unlocking plate 221, and the unlocking plate 221 is provided with a first top contact plate 222 and a second top contact plate 223. The first top contact plate 222 can touch the inclined top contact block 142 to make the locking member 14 leave the locking hole 122, and the left and right ends of the first top contact plate 222 are both beyond the left and right ends of the second top contact plate 223. Therefore, when the second top contact plate 223 can touch the support plate seat 12, the support plate seat 12 is in an unlocked state. Therefore, when the Y-axis 22 moves to this position, the second top contact plate 223 thereon can touch the support plate seat 12 to make the support plate seat 12 slide downward.

[0024] The laser device 3 is arranged on the Z axis 23. The laser device 3 includes a laser head 31, a hot drill sleeve 32, a power device 33, a base frame 34 and a lifting device 35. The base frame 34 is arranged on the Z axis 23. The hot drill sleeve 32 is limitedly rotated and arranged on the base frame 34. It can move up and down with the Z axis 23. The lower end of the hot drill sleeve 32 is conical, and a light hole 323 is opened at the center of the bottom. A threaded thread 321 is arranged above the cone of the outer wall of the hot drill sleeve 32, which can be used to tap the plate. A sliding cavity 322 is provided in the middle of the hot drill sleeve 32, and the laser head 31 is slidably arranged in the sliding cavity 322. The lifting device 35 is arranged on the base frame 34, which is an electric telescopic rod. The front end of the telescopic rod is connected to the laser head 31. When the telescopic rod rises upward, it can drive the laser head 31 to slide upward, and when the telescopic rod retracts downward, it can drive the laser head 31 to slide downward. A convex part 311 is provided on the laser head 31, and the convex part 311 is located in the sliding cavity 322.

[0025] The power device 33 includes a motor 331, which is a servo motor and can control the speed through a program. The motor 331 is provided with a first pulley 332, and the hot drill sleeve 32 is rotatably provided with a second pulley 333, and the first pulley 332 and the second pulley 333 are connected by a belt. The rotation of the motor 331 can drive the second pulley 333 to rotate. The middle inner ring of the second pulley 333 is evenly provided with a plurality of first grooves 3331. A keyway cavity 324 is provided, in which a sliding key 325 is slidably arranged, the upper end of the sliding key 325 touches one end of a first elastic member 326, and the other end touches the upper end of the keyway cavity 324, and inclined surfaces are arranged on both sides of the upper end of the sliding key 325 so that it can quickly slide into the first groove 3331, and the distance between each two first grooves 3331 is smaller than the width of the sliding key 325, so that the sliding member 325 can smoothly slide into the first groove 3331 each time it slides upward.

[0026] The light-through hole 323 is provided with a shielding cavity 327, in which a left shielding member 3271 and a right shielding member 3272 are slidably arranged, and one end of a second elastic member 3274 is arranged at the rear end of both, and the other end is respectively at the two ends of the shielding cavity 327, and through holes 3273 are provided on the left shielding member 3271 and the right shielding member 3272, and one end of a pull rope is arranged on the left shielding member 3271, and the other end passes through the through hole 3273 of the right shielding member 3272 and is upwardly connected to the sliding key 325, and one end of a pull rope is arranged on the right shielding member 3272, and the other end passes through the through hole 3273 of the left shielding member 3271 and is upwardly connected to the sliding key 325.

[0027] The second elastic member 3274 is a tension spring. In the initial state, that is, the lifting device 35 is in a retracted state, the lower end of the laser head 31 is close to the light hole 323. At this time, the protrusion 311 on the laser head 31 does not touch the sliding key 325. The left shielding member 3271 and the right shielding member 3272 are opened to both sides under the action of the second elastic member 3274, so that the light hole 323 is in a smooth state. At this time, the laser head 31 emits laser and compressed gas to cut the plate placed on the lower support plate 121, and the lifting device 35 is in a state of being compressed. The housing 35 extends upward, driving the laser head 31 to move upward, and the protrusion 311 on the laser head 31 contacts the sliding key 325, driving the sliding key 325 to move upward together, so that the upper end of the sliding key 325 slides into the first groove 3331, so that the hot drill sleeve 32 and the second pulley 333 are connected as a whole. When the sliding key 325 slides upward, one end of the pull rope is driven to move upward, thereby pulling the left shielding member 3271 and the right shielding member 3272 to move closer to the middle and merge together, thereby closing the light hole 323.

[0028] At this time, the motor 331 starts to rotate, and the Z-axis 23 also starts to work, driving the laser device 3 to slide downward as a whole. At this time, the hot drill sleeve 32 rotates rapidly to drill a hot melt hole on the plate. When the thread teeth 321 on the hot drill sleeve 32 are close to the plate, the motor 331 reduces the rotation speed and cooperates with the descending speed of the Z-axis 23 to tap the internal thread in the hot melt hole.

[0029] The center line of the hot drill sleeve 32 is located on the plane where the center lines of the left and right second top contact plates 223 are located. Therefore, when the hot drill sleeve 32 moves to any position, the corresponding support plate 121 below the heat transfer sleeve 32 is touched and slid down, so that the hot slag will not melt on the support plate 121 during laser cutting. At the same time, the bottom end of the hot drill sleeve 32 will not touch the support plate 121 during hot melt drilling, so that tapping and drilling can be completed smoothly.

[0030] The pull rope is a heat-resistant metal pull rope, and all of them pass through the light-through hole 323. The left shielding member 3271, the right shielding member 3272 and the hot drill sleeve 32 are all made of heat-resistant metal materials.

[0031] Its working principle or usage is as follows:

[0032] During normal laser cutting, the laser device 3 moves forward and backward following the Y-axis 22. The Y-axis 22 is provided with an unlocking plate 221. The unlocking plate 221 is provided with a first top contact plate 222 and a second top contact plate 223. The first top contact plate 222 can touch the inclined top contact block 142 to make the locking member 14 leave the locking hole 122. The left and right ends of the first top contact plate 222 are both beyond the left and right ends of the second top contact plate 223. Therefore, when the second top contact plate 223 can touch the support plate seat 12, the The support plate seats 12 are all in an unlocked state, so when the Y-axis 22 moves to this position, the second top contact plate 223 thereon can touch the support plate seat 12, causing the support plate seat 12 to slide downward, and the center line of the hot drill sleeve 32 is located on the plane where the center lines of the left and right second top contact plates 223 are located. Therefore, when the hot drill sleeve 32 moves to any position, the corresponding support plates 121 under the heat transfer sleeve 32 are all touched and slide down, so that the hot slag will not melt on the support plate 121 during laser cutting.

[0033] When tapping is required, the lifting device 35 extends upward, driving the laser head 31 to move upward, and the protrusion 311 on the laser head 31 touches the sliding key 325, driving the sliding key 325 to move upward together, so that the upper end of the sliding key 325 slides into the first groove 3331, so that the hot drill sleeve 32 and the second pulley 333 are connected as a whole, and when the sliding key 325 slides upward, it drives one end of the pull rope to move upward, thereby pulling the left shielding member 3271 and the right shielding member 3272 to move closer to the middle and merge together, thereby closing the light hole 323.

[0034] At this time, the motor 331 starts to rotate, and the Z axis 23 also starts to work, driving the laser device 3 to slide downward as a whole, and the hot drill sleeve 32 rotates rapidly at this time to drill a hot melt hole on the plate. When the hot drill sleeve 32 rotates, the laser head 31 does not rotate. A rolling bearing is provided on the upper end of the protrusion 311, and the sliding key 325 contacts the rolling bearing, so that the sliding key 325 can rotate rapidly relative to the laser head 31. When the threaded thread 321 on the hot drill sleeve 32 approaches the plate, the motor 331 reduces the speed and cooperates with the speed of the Z axis 23 to tap the internal thread in the hot melt hole. At this time, the laser head 31 is far away from the lower end of the hot drill sleeve 32, and the high temperature generated by the hot drill sleeve 32 will not affect the laser head 31. At the same time, the light hole 323 is closed, and the residue generated during hot melting will not enter the sliding cavity 322, thereby eliminating the residue from affecting the laser head 31.

[0035] At the same time, the laser head 31 can be used to pre-cut holes in the plate, and then the hot drill sleeve 32 can be used to expand the hole and tap the hole.

[0036] After the tapping is completed, the lifting device 35 begins to retract, causing the laser head 31 to descend, and the sliding key 325 slides downward under the action of the first elastic member 326 and leaves the first groove 3331, so that the hot drill sleeve 32 is disconnected from the power device 33, so that the hot drill sleeve 32 will not rotate during laser cutting, and the lower end of the laser head 31 is close to the light hole 323. At this time, the protrusion 311 on the laser head 31 does not touch the sliding key 325, and the left shielding member 3271 and the right shielding member 3272 are opened to both sides under the action of the second elastic member 3274, so that the light hole 323 is in a smooth state, and the laser cutting state is restored.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
