[0001] This utility model belongs to the field of laser cutting technology, specifically a quick-change device for laser cutting machine cutting heads. Background Technology

[0002] A laser cutting machine cutting head changing mechanism is a device that allows laser cutting machines to change cutting heads quickly. This device typically consists of a main plate fixed to the machine and a tool plate connecting different tools. A precise mechanical locking mechanism and electrical connectors enable rapid and accurate tool replacement. Current laser cutting machine cutting head quick-change devices lack adjustable functionality. When changing cutting heads of different sizes, the inability to adjust makes it impossible to fix different sizes of cutting heads, reducing the versatility of the device. Therefore, a laser cutting machine cutting head quick-change device with adjustable functionality is needed. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a quick-change device for laser cutting machine cutting heads, which solves the problem that the quick-change device for laser cutting machine cutting heads does not have a free adjustment function. When changing cutting heads of different sizes, it is impossible to fix the cutting heads of different sizes because it cannot be adjusted, which reduces the versatility of the quick-change device for laser cutting machine cutting heads.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-change device for a laser cutting machine cutting head, comprising a connecting plate, a first fixing block fixedly connected to the bottom side of the connecting plate, two connecting rods mounted on the first fixing block, a first support plate mounted on one end of each connecting rod, the first support plate being fixedly connected to the connecting plate, a pushing block provided on one side of the first support plate, a threaded rod threadedly engaged on the pushing block, one end of the threaded rod being connected to the connecting plate via a bearing, and a rotating handle fixedly connected to the other end of the threaded rod, a second fixing block provided on one side of the pushing block, the second fixing block being engaged with the connecting rods, a cutting head body mounted between the first fixing block and the second fixing block, and a spring sleeved on the outside of the connecting rod, one end of the spring being fixedly connected to the first fixing block.

[0005] As a further embodiment of this utility model: mounting plates are fixedly connected to both sides of the connecting plate, and two nuts are threaded onto the mounting plates.

[0006] As a further embodiment of this utility model: a second support plate is installed on one side of the connecting plate, and a heat dissipation shell is fixedly connected to the bottom side of the second support plate.

[0007] As a further embodiment of this utility model: two reinforcing plates are installed on one side of the second support plate, and the reinforcing plates are fixedly connected to the connecting plate.

[0008] As a further embodiment of this utility model: a first dustproof net is fixedly connected to one side of the heat dissipation shell, and a second dustproof net is installed on the other side of the heat dissipation shell.

[0009] As a further embodiment of this utility model: a third support plate is fixedly connected to the inner wall of the heat dissipation shell, a motor is installed on one side of the third support plate, and a fan is fixedly connected to one side of the motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This laser cutting machine cutting head quick-change device, by setting up a first fixed block, connecting rod, first support plate, pushing block, second fixed block, spring, cutting head body, rotating handle, and threaded rod, allows the operator to place the cutting head body between the first and second fixed blocks when installing cutting head bodies of different sizes. Then, the operator rotates the rotating handle to drive the threaded rod to rotate, which pushes the pushing block upward. The pushing block then pushes the second fixed block to move and causes the spring to contract until the second fixed block is tightly fitted with the cutting head body. This facilitates the quick installation of cutting head bodies of different sizes and prevents the device from being ineffective in fixing the cutting head body due to different sizes of the cutting head body being replaced, thus improving the functionality and versatility of the device.

[0012] 2. The laser cutting machine cutting head quick change device consists of a cutting head body, a heat dissipation shell, a third support plate, a motor, and a fan. When the cutting head is working, the operator starts the motor on the third support plate, which drives the fan to rotate. The fan blows air out from one side of the heat dissipation shell, thereby cooling the cutting head body and preventing overheating caused by prolonged operation, which could damage the cutting head body. This improves the functionality of the replacement device. Attached Figure Description

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a quick replacement device for a laser cutting machine cutting head, including a connecting plate 1, with mounting plates 11 fixedly connected to both sides of the connecting plate 1. Two nuts 12 are threaded onto the mounting plates 11. Because of the nuts 12, when installing the replacement device, the operator rotates the nuts 12 threaded onto the mounting plates 11 to make the nuts 12 threaded onto the installation location, which facilitates quick and stable installation of the replacement device, saves manpower and resources, and improves installation efficiency.

[0019] A second support plate 13 is installed on one side of the connecting plate 1. A heat dissipation shell 14 is fixedly connected to the bottom side of the second support plate 13. A first fixing block 2 is fixedly connected to the bottom side of the connecting plate 1. Two connecting rods 3 are installed on the first fixing block 2. A first support plate 4 is installed at one end of the connecting rod 3. The first support plate 4 is fixedly connected to the connecting plate 1. A push block 5 is provided on one side of the first support plate 4. A threaded rod 10 is threadedly engaged on the push block 5. One end of the threaded rod 10 is connected to the connecting plate 1 through a bearing. A rotating handle 9 is fixedly connected to the other end of the threaded rod 10. A second fixing block 6 is provided on one side of the push block 5. Two reinforcing plates 15 are installed on one side of the second support plate 13. The reinforcing plates 15 are fixedly connected to the connecting plate 1. Because of the reinforcing plates 15, the connecting plate 1 is reinforced and fixed, preventing the connecting plate 1 from breaking accidentally after long-term use, which would damage the replacement device and improve the stability of the connecting plate 1.

[0020] A first dustproof net 16 is fixedly connected to one side of the heat dissipation shell 14, and a second dustproof net 17 is installed on the other side of the heat dissipation shell 14. Because of the first dustproof net 16, dust in the air is blocked from entering the interior of the heat dissipation shell 14, preventing dust from accumulating in large quantities inside the heat dissipation shell 14, which would reduce the heat dissipation efficiency of the replacement device and improve the heat dissipation stability of the replacement device. The second fixing block 6 is interlocked with the connecting rod 3. Because of the connecting rod 3, the second fixing block 6 is limited to prevent it from falling off accidentally during movement, thus improving the stability of the second fixing block 6 during movement. A cutting head body 8 is installed between the first fixing block 2 and the second fixing block 6. A spring 7 is sleeved on the outside of the connecting rod 3, and one end of the spring 7 is fixedly connected to the first fixing block 2. A third support plate 18 is fixedly connected to the inner wall of the heat dissipation shell 14. A motor 19 is installed on one side of the third support plate 18, and a fan 20 is fixedly connected to one side of the motor 19.

[0021] The working principle of this utility model is as follows: When installing the replacement device, the operator rotates the nut 12 threaded on the mounting plate 11 to make the nut 12 threaded with the installation location. When installing the cutting head body 8 of different sizes, the operator places the cutting head body 8 between the first fixing block 2 and the second fixing block 6, and then rotates the handle 9 to drive the threaded rod 10 to rotate. The threaded rod 10 pushes the pushing block 5 to move upward, and the pushing block 5 pushes the second fixing block 6 to move and causes the spring 7 to contract until the second fixing block 6 and the cutting head body 8 are tightly fitted. When the cutting head is working, the operator starts the motor 19 on the third support plate 18. The motor 19 makes the fan 20 rotate, and the fan 20 blows air out from one side of the heat dissipation shell 14, thereby dissipating heat from the cutting head body 8.
