Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting machines, in particular to a fixing mechanism for a laser cutting head. Background Art

[0002] Laser cutting machine is a processing equipment that uses high-energy-density laser beam to cut workpieces. It uses laser technology to cut and can cut various materials with high precision and high speed. It is widely used in metal processing, automobile manufacturing, electronic product manufacturing and other industries. However, the laser cutting head is an important component of the laser cutting machine. It is used to focus the laser beam and guide it to the surface of the workpiece to achieve the function of precise cutting of the workpiece.

[0003] The traditional laser cutting head fixing mechanism usually has a special groove or slot on the laser cutting machine or machine tool for placing and fixing the laser cutting head. Then, the screw will pass through the fixing hole of the laser cutting head or its bracket, and the laser cutting head will be fixed in the mounting groove by tightening the nut or other fixing device.

[0004] The traditional fixing mechanism of the laser cutting head has the following problems: since it needs to be fixed with screws, the laser cutting head is relatively cumbersome to adjust. When the laser cutting head needs to be replaced or the position needs to be adjusted, the screws need to be removed and re-fixed. At the same time, the clamping force cannot be adjusted according to the size of the laser cutting head. The operation is relatively time-consuming and not flexible enough. For this reason, we propose a fixing mechanism for the laser cutting head. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a fixing mechanism for a laser cutting head, which can adapt to laser cutting heads of different sizes and shapes, improve the flexibility of the fixing mechanism of the laser cutting head, and effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a fixing mechanism for a laser cutting head, comprising a mounting plate and a fixing mechanism;

[0007] Mounting plate: The lower surface of the mounting plate is fixedly connected with evenly distributed support columns, and the bottom ends of the support columns are fixedly connected to the upper surface of a fixed plate;

[0008] Fixing mechanism: It is arranged inside the fixing plate, and the bottom end of the fixing mechanism extends to the outside of the lower surface of the fixing plate. A laser head is provided at the lower end of the interior of the fixing mechanism. The input end of the laser head is electrically connected to the output end of the external single-chip microcomputer. The overall diameter of the clamping plate can be adjusted at any time according to the size of the laser cutting head, so that it can adapt to laser cutting heads of different sizes and shapes, thereby improving the flexibility of the fixing mechanism of the laser cutting head.

[0009] Furthermore, it also includes mounting holes, which are all opened on the upper surface of the mounting plate to facilitate installation on the laser cutting machine.

[0010] Furthermore, the fixing mechanism includes a rubber strip, a support rod, a guide slot and a clamping plate. There are six guide slots, and the six guide slots are all opened on the upper surface of the fixed plate. The inside of the guide slot is slidably connected to the support rod, and the bottom end of the support rod is fixedly connected to the clamping plate. The inner side of each clamping plate is provided with a rubber strip, and the rubber strip is installed in conjunction with a laser head to achieve precise fixation.

[0011] Furthermore, the fixing mechanism also includes a limiting plate, which is fixedly connected to the top of the support rod, and the width of the limiting plate is greater than the width of the adjacent guide slot, ensuring that the support rod can move stably in the guide slot without falling off.

[0012] Furthermore, the fixing mechanism also includes a connecting rod, a U-shaped seat, a limiting column, an internal threaded ring and an avoidance groove. The limiting columns are slidably connected to the sliding holes on the lower surface of the fixed plate, and the bottom ends of the limiting columns are fixedly connected to the upper surface of an internal threaded ring. The outer surface of the internal threaded ring is provided with six avoidance grooves. The U-shaped seat is fixedly connected to the inner side surfaces of the six clamping plates respectively. The U-shaped seat and the adjacent avoidance grooves are rotatably connected with a connecting rod through a pin shaft, so that it can adapt to laser heads of different sizes and shapes.

[0013] Furthermore, the fixing mechanism also includes a rotating groove and a screw. The rotating groove is opened in the middle of the fixed plate. The inner wall of the rotating groove is rotatably connected to the screw through a bearing. The bottom end of the screw is threadedly connected to the middle of the internal thread ring, so that the overall diameter of the clamping plate can gradually increase or decrease.

[0014] Furthermore, it also includes a round block, which is rotatably connected to the sliding mouth in the middle of the upper surface of the mounting plate, the lower surface of the round block is fixedly connected to the top of the screw, and the upper surface of the round block is provided with a hexagonal hole to drive the fixing mechanism to operate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the fixing mechanism of the laser cutting head has the following advantages:

[0016] The inner thread ring moves downward along the inner wall of the sliding hole through the limit column. During the movement of the inner thread ring, the connecting rod is driven to rotate to a certain extent, and the rotating movement of the connecting rod is transmitted to the clamping plate on the U-shaped seat, so that it is driven to move smoothly in the guide slide groove through the support rod and synchronously approach the center of the fixed disk. At the same time, when the support rod slides in the guide slide groove, since the width of the limit plate is greater than the groove width of the adjacent guide slide groove, it can ensure that the support rod can move stably in the guide slide groove without falling off. When the clamping plate gradually approaches the laser head, the rubber strip on each clamping plate will contact the outer surface of the laser head. Finally, through the continuous movement of the inner thread ring, the rubber strip is fully in contact with the laser head to achieve precise fixation. The height of the inner thread ring moving downward can be controlled by the screw, so that the overall diameter of the six clamping plates can be gradually increased or decreased, so that the size of the clamping plate can be adjusted at any time according to the size of the laser head, thereby improving the flexibility of the fixing mechanism of the laser cutting head.

[0023] See also Figure 1-4 , this embodiment provides a technical solution: a fixing mechanism for a laser cutting head, comprising a mounting plate 1 and a fixing mechanism 5;

[0024] Mounting plate 1: The lower surface of the mounting plate 1 is fixedly connected with evenly distributed support columns 8, and the bottom ends of the support columns 8 are fixedly connected to the upper surface of a fixed plate 7. The mounting plate 1 also includes mounting holes 2, which are all opened on the upper surface of the mounting plate 1. The mounting plate 1 is placed at a designated position on the laser cutting machine, and the fixing mechanism 5 on the fixed plate 7 and the laser head 6 in the fixing mechanism 5 are fixed to the machine through the mounting holes 2 using suitable screws or bolts. The mounting plate 1 also includes a round block 4, which is rotatably connected to the sliding mouth in the middle of the upper surface of the mounting plate 1. The lower surface of the round block 4 is fixedly connected to the top of the screw 510. A hexagonal hole 3 is opened on the upper surface of the round block 4. First, the laser head 6 is placed between the clamping plates 504, and then an external hexagonal screwdriver is inserted into the hexagonal hole 3 and rotated to drive the round block 4 to rotate, and then the round block 4 transmits the rotation to the screw 510;

[0025] The fixing mechanism 5 is arranged inside the fixing plate 7, and the bottom end of the fixing mechanism 5 extends to the outside of the lower surface of the fixing plate 7. The lower end of the fixing mechanism 5 is provided with a laser head 6. The input end of the laser head 6 is electrically connected to the output end of the external single-chip microcomputer. The fixing mechanism 5 includes a rubber strip 501, a support rod 505, a guide slide 506 and a clamping plate 504. There are six guide slides 506. The six guide slides 506 are all opened on the upper surface of the fixing plate 7. The inside of the guide slide 506 is slidably connected to the support rod 505. The bottom end of the support rod 505 is fixedly connected to the clamping plate 504. The inner side of each clamping plate 504 is provided with a rubber strip 501. The rubber strip 501 is installed in conjunction with a laser head 6. The fixing mechanism 5 also includes a limit plate 507. The pieces 507 are all fixedly connected to the top of the support rod 505, and the width of the limiting piece 507 is greater than the width of the adjacent guide slot 506. The fixing mechanism 5 also includes a connecting rod 502, a U-shaped seat 503, a limiting column 509, an internal threaded ring 511 and an avoidance groove 512. The limiting column 509 is slidably connected to the sliding hole on the lower surface of the fixed plate 7, and the bottom end of the limiting column 509 is fixedly connected to the upper surface of an internal threaded ring 511. The outer surface of the internal threaded ring 511 is provided with six avoidance grooves 512. The U-shaped seat 503 is fixedly connected to the inner side surfaces of the six clamping plates 504 respectively. The U-shaped seat 503 and the adjacent avoidance groove 512 are rotatably connected with the connecting rod 502 through a pin shaft. The fixing mechanism 5 also includes a rotating groove 508 and a screw 510. The rotating groove 50 8 is opened in the middle of the fixed disk 7, and the inner wall of the rotating groove 508 is connected to the screw rod 510 through the bearing rotation, and the bottom end of the screw rod 510 is threadedly connected to the middle part of the internal thread ring 511. The screw rod 510 starts to rotate, and the rotation of the screw rod 510 is connected with the internal thread ring 511 through the thread connection, so that the internal thread ring 511 moves downward along the inner wall of the sliding hole through the limit column 509. During the movement of the internal thread ring 511, the connecting rod 502 is driven to rotate to a certain extent, and the rotation of the connecting rod 502 is transmitted to the clamping plate 504 on the U-shaped seat 503 with the pin shaft in the avoidance groove 512 as the center, so that it is driven by the support rod 505 to move smoothly in the guide groove 506 and synchronously approach the center of the fixed disk 7. At the same time, the support rod 505 moves in the guide groove 506. 6, since the width of the limiting piece 507 is greater than the width of the adjacent guide slot 506, it can ensure that the support rod 505 can move stably in the guide slot 506 without falling off. When the clamping plate 504 gradually approaches the laser head 6, the rubber strip 501 on each clamping plate 504 will contact the outer surface of the laser head 6, and finally the rubber strip 501 is completely in contact with the laser head through the continuous movement of the internal thread ring 511, so that precise fixation is achieved. The height of the internal thread ring 511 moving downward can be controlled by the screw 510, so that the overall diameter of the six clamping plates 504 can be gradually increased or decreased, and the size of the clamping plate can be adjusted at any time according to the size of the laser head 6, thereby achieving the goal of adapting to laser heads 6 of different sizes and shapes.Improved the flexibility of the fixing mechanism of the laser cutting head.

[0026] The working principle of the fixing mechanism of the laser cutting head provided by the present invention is as follows: first, the laser head 6 is placed between the clamping plates 504, and then an external hexagonal screwdriver is inserted into the hexagonal hole 3 and rotated to drive the round block 4 to rotate, and then the round block 4 transmits the rotation to the screw rod 510, and the screw rod 510 starts to rotate. The rotation of the screw rod 510 is connected with the internal thread ring 511 through the threaded connection, so that the internal thread ring 511 moves downward along the inner wall of the sliding hole through the limiting column 509. During the movement of the internal thread ring 511, the connecting rod 502 is driven to rotate to a certain extent, and with the pin shaft in the avoidance groove 512 as the center, the rotation of the connecting rod 502 is transmitted to the clamping plate 504 on the U-shaped seat 503, so that it is driven by the support rod 505 to move smoothly in the guide slot 506 and synchronously approach the center of the fixed disk 7. At the same time, when the support rod 505 slides in the guide slot 506, since the width of the limiting piece 507 is larger than the adjacent guide slot 5 06 slot width, thereby ensuring that the support rod 505 can move stably in the guide slide groove 506 without falling off, when the clamping plate 504 gradually approaches the laser head 6, the rubber strip 501 on each clamping plate 504 will contact the outer surface of the laser head 6, and finally the rubber strip 501 will be fully in contact with the laser head through the continuous movement of the internal threaded ring 511, achieving precise fixation, and the height of the internal threaded ring 511 can be controlled by the screw 510, so that the overall diameter of the six clamping plates 504 can be gradually increased or decreased, and then the size of the clamping plate can be adjusted at any time according to the size of the laser head 6, thereby realizing the ability to adapt to laser heads 6 of different sizes and shapes, and improving the flexibility of the fixing mechanism of the laser cutting head. Then, the mounting plate 1 is placed at the designated position on the laser cutting machine, and the fixing mechanism 5 on the fixing plate 7 and the laser head 6 in the fixing mechanism 5 are fixed to the machine using suitable screws or bolts through the mounting hole 2.

[0027] It is worth noting that the specific model of the laser head 6 disclosed in the above embodiment is BM110, and the external single chip microcomputer controls the operation of the laser head 6 using a method commonly used in the prior art.
