[0003] The existing related technology often has the following defects: before using the laser cutting machine to cut the laser tube pin, the laser tube often needs to be fixed. During the process of fixing the laser tube pin, due to the different structures of the laser tube, the two sides are uncertain concave, convex or flat structures, which leads to the need to set up a special tool to realize the stable clamping work of different structures of the laser tube, thereby reducing the application range of the laser tube clamping structure.

[0032] Please see Figures 1-9The application provides a technical scheme: a laser cutting machine for laser tube pin repair, which comprises a base 1, a bidirectional screw rod 3 is rotationally connected in the base 1, opposite threads are formed in the two sides of the bidirectional screw rod 3, a guide rail 2 is fixedly connected to the upper surface of the base 1, a clamping plate 4 is slidably connected to the side wall of the guide rail 2, a vertical plate 8 is fixedly installed on the upper surface of the base 1, a moving pin 10 is slidably connected in the vertical plate 8, an installation sheet 11 is fixedly connected to the upper end of the moving pin 10, a laser cutting device 12 is fixedly connected to the side wall of the installation sheet 11, and a laser cutting head 13 is fixedly installed on the side wall of the laser cutting device 12, and the laser cutting machine further comprises a filling structure 5 arranged on the upper surface of the clamping plate 4 and used for further stabilizing the laser tube after clamping the laser tube with different side edges, the filling structure 5 comprises a rotating pin 502 rotationally connected to the upper end of the clamping plate 4, a rotating plate 501 fixedly connected to the upper end of the rotating pin 502, and a limiting frame 503 fixedly connected to the upper end of the rotating plate 501, a lock catch structure 6 arranged between the clamping plate 4 and the rotating plate 501 and used for controlling the fixing of the rotating plate 501 after rotation, and a moving structure 7 arranged on the surface of the limiting frame 503 and used for clamping the laser tube with different machining degrees. Through the arrangement of the filling structure 5, the combination of the sliding strip 510 and the elastic rope 512 can be self-adaptive to different radian according to the concave surface, the convex surface or the plane structure of the laser tube, and the flexible filling characteristics of the sandbag 505 can adapt to the plane or irregular surface, so that the laser tube with various structures can be stably clamped, the clamping efficiency of the same machining tool for different types of laser tubes is improved to a certain extent, the machining requirement of the laser tube with different shapes is met, through the arrangement of the lock catch structure 6, the flexible support or clamping work on the inner side or the outer side of the laser tube is facilitated through the flexible turning of the two rotating plates 501, the use performance of the machining tool for the laser tube is further improved, through the arrangement of the moving structure 7, the flexible moving work of the push frame 71 is facilitated, the push frame 71 is moved to be misaligned and protrudes the anti-skid pad 76, the push frame 71 is used as a clamping surface to clamp the laser tube, so that the machining work of the laser tube with high precision requirement is facilitated, the anti-skid pad 76 is directly used to clamp the laser tube, the friction force for fixing the laser tube is increased, and the phenomenon that the surface of the laser tube is clamped and damaged is avoided.
[0033] The specific arrangement and role of the filling structure 5, the lock catch structure 6 and the moving structure 7 will be described below.
[0034] As Figures 1-5 and Figure 7As shown, the filling structure 5 also includes a connecting frame 504 fixedly connected to the end of the limiting frame 503. Two limiting strips 507 are slidably connected inside the connecting frame 504. Push plates 509 are fixedly connected to the ends of the two limiting strips 507. Sandbags 505 are fixedly connected to the surface of the push plates 509. Sandbags 505 are filled with sand 511 inside. A first drive rod 508 is threadedly connected inside the connecting frame 504. The first drive rod 508 and the push plate 509 are rotatably connected internally. One side of the limiting frame 503 is an arc-shaped concave surface. After the laser tube is clamped and fixed using the two limiting frames 503, rotating the first drive rod 508 can achieve horizontal driving of the push plate 509. This allows for further pushing of the sandbags 505. The sandbags 505 are eventually squeezed and filled between the laser tube and the push plate 509, thus achieving stable clamping of the laser tube. Several rubber protrusions 506, hemispherical in shape, are glued to the side of the sandbag 505 away from the push plate 509. The hemispherical rubber protrusions 506 increase the friction between the sandbag 505 and the laser tube, further improving the stability of fixing the laser tube. Two rows of slide bars 510 are slidably connected inside the limiting frame 503. Each row of slide bars 510 has several limiting holes on its surface, and elastic ropes 512 slide through the inner sides of these holes. Both ends of the elastic ropes 512 are fixedly connected to the limiting frame 503. During the process of driving the limiting frame 503 to clamp the laser tube, the slide bars 510 are pressed against the side of the laser tube with different arc-shaped structures by the elastic force of the elastic ropes 512. Subsequently, during the process of driving the sandbag 505, the sandbag 505 is restricted by the two rows of slide bars 510 and moves only towards the side of the laser tube, further improving the stability of clamping the laser tube.
[0035] like Figures 1-4 and Figures 8-9 As shown, the locking structure 6 includes a reserved groove 61 on one side of the rotating plate 501. Two guide grooves 65 are formed on the bottom wall of the reserved groove 61. A sliding plate 62 is slidably connected to the inner wall of the two guide grooves 65. A pin 64 is fixedly connected to the lower surface of the sliding plate 62, and the pin 64 slides through the bottom side of the rotating plate 501. Two insertion holes 66 are formed on the upper surface of the clamping plate 4, and the size of the insertion holes 66 matches the size of the pin 64. Sliding the sliding plate 62 pulls the pin 64 out from the inside of the insertion hole 66. At this time, the rotating plate 501 above the clamping plate 4 can be rotated. After the rotating plate 501 is flipped, the sliding plate 62 slides on the inner wall of the guide groove 65, which restricts the movement direction of the sliding plate 62. Inserting the pin 64 into the corresponding insertion hole 66 can achieve the locking and fixing work between the flipped clamping plate 4 and the rotating plate 501. A spring 63 is fixedly connected between the inner side of the reserved groove 61 and the sliding plate 62. When the slide plate 62 is released, it will be inserted into the inside of the corresponding socket 66 by the elastic force of the spring 63.
[0036] like Figures 1-6 As shown, the moving structure 7 includes two positioning strips 73 fixedly connected inside the rotating plate 501. Push frames 71 are fixedly connected to the ends of the two positioning strips 73. Several first misalignment grooves 74 and several second misalignment grooves 75 are provided on both sides of the push frame 71, and the first and second misalignment grooves 74 and 75 are arranged in a staggered manner. By setting the first and second misalignment grooves 74 and 75, not only is the misalignment movement between the two facilitated, but the friction force is also increased when using the limiting frame 503 and the push frame 71 at the positions where the second and first misalignment grooves 75 and 74 are respectively provided, further improving the stability of clamping the laser tube using the push frame 71 as the clamping surface. A second drive rod 72 is internally threaded to the rotating plate 501, and the second drive rod 72 is internally rotatably connected to the push frame 71. Rotating the second drive rod 72 facilitates the pushing of the limiting frame 503. Two anti-slip pads 76 are glued to the surface of the limiting frame 503. The anti-slip pad 76 increases the stability of clamping the laser tube, preventing damage. The surface of the anti-slip pad 76 has several slots of the same size as the second misalignment groove 75. These slots on the anti-slip pad 76 are also designed to facilitate the movement of the push frame 71 during operation.
[0037] Working principle: First, the aluminum alloy laser tube is placed on the base 1. By rotating the bidirectional lead screw 3, the two clamping plates 4 are driven to slide towards or away from each other along the guide rail 2 using the reverse threads on both sides. The spacing of the clamping plates 4 is initially adjusted according to the width of the laser tube to achieve basic positioning. After the laser tube is clamped and fixed using two limiting frames 503, rotating the first drive rod 508 can drive the push plate 509 to move horizontally, thereby pushing the sandbag 505 to fill the gap between the laser tube and the push plate 509, regardless of whether the side of the laser tube is concave. Whether the surface is convex or flat, the sand and gravel 511 inside the sandbag 505 can adhere tightly to the surface of the laser tube after being compressed, achieving stable clamping. A hemispherical rubber protrusion 506 is glued to the side of the sandbag 505 away from the push plate 509, increasing the friction between the sandbag 505 and the laser tube, further improving the stability of the fixation and preventing displacement of the laser tube during processing. When the driving limit frame 503 clamps the laser tube, the slide bar 510 adheres to the side of the laser tube under the elastic force of the elastic rope 512, and subsequently drives the sandbag 505... At time 5, the slider 510 can restrict the sandbag 505 to move only towards the side of the laser tube, preventing the sandbag 505 from shifting and ensuring the stability and accuracy of clamping. After clamping the laser tube, the stud 9 is rotated first to drive the mounting plate 11, which in turn enables the synchronous driving of the laser cutter 12 and the laser cutting head 13 until the laser cutting head 13 is adjusted to the position of the laser tube pin. Then, the laser cutter 12 is started to cut the laser tube pin. By setting the filling structure 5, the combination of slider 510 and elastic rope 512 can adapt to different curvatures for the concave, convex or planar structure of the laser tube, while the flexible filling characteristics of the sandbag 505 can adapt to flat or irregular surfaces, ensuring that laser tubes of various structures are stably clamped. To a certain extent, this improves the clamping efficiency of different types of laser tubes using the same processing fixture, meets the processing needs of laser tubes of different shapes, and thus improves the applicability of the processing fixture and the stability of subsequent laser cutting of the laser tube pins.
[0038] Sliding slide plate 62 pulls pin 64 out from the inside of socket 66. At this time, rotating plate 501 above clamping plate 4 can be rotated. After rotating plate 501 is flipped, slide plate 62 slides on the inner wall of guide groove 65, which restricts the movement direction of slide plate 62. Inserting pin 64 into the inside of corresponding socket 66 can realize the locking and fixing work between clamping plate 4 and rotating plate 501 after flipping. Releasing slide plate 62, slide plate 62 will be inserted into the inside of corresponding socket 66 by the elastic force of spring 63, which improves the stability of fixing rotating plate 501 after twisting. By setting the locking structure 6, the flexible flipping of the two rotating plates 501 facilitates the flexible support or clamping work of the inner or outer side of the laser tube. Supporting the inner side of the laser tube facilitates the support work of hollow laser tube, further improving the performance of the processing fixture for laser tube.
[0039] By setting the first misaligned groove 74 and the second misaligned groove 75 in a staggered arrangement, it is convenient to move the push frame 71 to the position protruding from the limiting frame 503. Rotating the second drive rod 72 facilitates the pushing of the limiting frame 503, moving it to the side closer to the fixed plate. At this time, the anti-slip pad 76 can play its role. The anti-slip pad 76 increases the stability of clamping the laser tube and avoids damage to the laser tube. The groove on the anti-slip pad 76 is also designed to facilitate the movement of the push frame 71. Rotating the second drive rod 72 in the opposite direction moves the push frame 71 to the position protruding from the limiting frame 503. At this time, the push frame 71 can act as a clamping part to clamp the laser tube. Using the push frame 71 as the clamping surface to clamp the laser tube improves accuracy. For high-precision laser tube processing, the first misalignment groove 74 and the second misalignment groove 75 are provided. This not only facilitates the misalignment movement between the two but also increases the friction when the limiting frame 503 and the push frame 71 are used at the positions where the second misalignment groove 75 and the first misalignment groove 74 are respectively opened. This further improves the stability of clamping the laser tube using the push frame 71 as the clamping surface. The moving structure 7 facilitates the flexible movement of the push frame 71. The anti-slip pad 76 protrudes from the moving misalignment of the push frame 71. Using the push frame 71 as the clamping surface to clamp the laser tube facilitates the processing of laser tubes with high precision requirements. The anti-slip pad 76 directly clamps the laser tube, which not only increases the friction for fixing the laser tube but also avoids the phenomenon of pinching damage to the surface of the laser tube during clamping.
