Description

Technical Field

[0001] This utility model relates to the field of laser cutting heads, specifically a high-power laser cutting head. Background Technology

[0002] A high-power laser cutting head is a core device used in the field of laser cutting. It typically refers to a professional equipment component that can carry and output a high-power laser beam to achieve high-precision and high-efficiency cutting of various materials. It has an excellent optical system, precise beam control, and efficient cooling and heat dissipation mechanism, and can adapt to the cutting needs of different materials and thicknesses. It is widely used in many industrial fields such as metal processing, automobile manufacturing, and aerospace.

[0003] During the laser cutting process, the high-power laser cutting head uses an internal precision optical focusing system to accurately focus the high-energy-density laser beam generated by the laser onto the surface of the material to be cut. When the high-power laser beam irradiates the material, the material absorbs the energy of the laser, instantly causing the temperature of the material in the irradiated area to rise sharply to the melting point or even the boiling point, and the material melts or vaporizes rapidly.

[0004] When existing laser cutting heads cut materials, the distance between the laser cutting head and the material is relatively close, and the surface of the material has uneven protrusions. If the laser cutting head collides with a protrusion, the impact generated by the collision can damage the precision instrument components inside the laser cutting head. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-power laser cutting head to solve the technical problem that when the laser cutting head collides with a protrusion on the plate during operation, the impact generated by the collision will damage the precision instrument components inside the laser cutting head.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power laser cutting head, comprising a cutter and a protective ring, wherein a mounting post is fixed to the bottom end of the cutter, a fixing ring is sleeved on the outer wall of the mounting post, a protective ring is connected to the bottom of the fixing ring, an anti-collision plate is installed on the outer wall of the protective ring, a connecting post is fixed to one side of the anti-collision plate, a contact plate is connected to the end of the connecting post, a conductive component is installed inside the protective ring, a controller is provided on the outer wall of the protective ring, and a first wire and a second wire are connected inside the controller.

[0007] By adopting the above technical solution, the problem of damage to the precision instrument components inside the laser cutting head caused by the impact of the collision is solved. When the anti-collision plate comes into contact with an object, the first and second conductive blocks on one side of the contact plate respectively contact and adhere to a set of first and second conductive plates. The current on the first conductive plate flows into the second conductive plate through the contact plate, so that the first and second conductors form a closed loop through the conductive components.

[0008] The present invention is further configured such that the conductive component includes a first conductive ring and a second conductive ring, and multiple sets of conductive posts are fixed to the outer walls of the first and second conductive rings. The first and second conductive rings are respectively connected to multiple sets of first conductive plates and second conductive plates through the conductive posts.

[0009] Preferably, multiple sets of first conductive plates are connected to the first conductive ring via conductive posts, so that the current in the first conductive ring can flow into any set of conductive plates through the conductive posts. The second conductive ring is connected to multiple sets of second conductive plates via conductive posts, so that the current on the second conductive plates can flow into the second conductive ring through the conductive posts.

[0010] The present invention is further configured such that the first conductive ring is connected to the first wire, and the second conductive ring is connected to the second wire.

[0011] Preferably, the first wire is connected to the power supply, and the current in the power supply flows into the first conductive coil through the first wire, while the current in the second conductive coil can flow into the controller through the second wire.

[0013] Preferably, when the protective ring moves to the inner end of the protective ring, the first conductive block and the second conductive block on one side of the contact plate respectively come into contact with a set of first conductive plates and second conductive plates, so that the current in the first conductive plate flows into the second conductive plate through the first conductive block and the second conductive block.

[0014] The present invention is further configured such that a spring is sleeved on the outer wall of the connecting column, and the ends of the spring are respectively connected to the protective ring and the anti-collision plate.

[0015] Preferably, when the bumper plate collides with an object, the bumper plate compresses the spring, and when the bumper plate is no longer in contact with the object, the spring pushes the bumper plate to reset.

[0016] The present invention is further configured such that an optical cable is connected to the top of the cutter, and a laser head is installed at the bottom of the cutter.

[0017] Preferably, the optical fiber transmits energy to the inside of the cutter, and the laser head emits a laser line with extremely high temperature, enabling the cutter to cut the board.

[0018] The present invention is further configured such that an installation ring is fixed to the outer wall of the fixing ring, a threaded rod is provided inside the installation ring, and a fixing knob is connected to the end of the threaded rod.

[0019] Preferably, the fixing knob is manually rotated, which pushes the threaded rod to move inward into the fixing ring.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem that the impact generated by the collision of the laser cutting head can damage the precision instrument components inside the laser cutting head by setting up a cutter, a collision plate, a contact plate, a conductive component, and a controller. When the collision plate comes into contact with an object, the first conductive block and the second conductive block on one side of the contact plate respectively come into contact with a set of first conductive plates and second conductive plates. The current on the first conductive plate flows into the second conductive plate through the contact plate, so that the first conductor and the second conductor form a closed loop through the conductive component. The controller controls the cutter to stop moving, thereby avoiding large impacts between the cutter and external objects.

[0024] 2. This utility model uses a fixing ring, a mounting ring, a threaded rod, and a fixing plate. The cutter is fixedly mounted on the mounting post at the bottom of the cutter by the fixing device. When installing the fixing device, it is only necessary to manually rotate the fixing knob. The fixing knob drives the threaded rod to rotate. Since the threaded rod is connected to the mounting ring by threads, the threaded rod pushes the fixing plate to squeeze the mounting post, so that the fixing device is fixedly mounted on the outer wall of the mounting post, which facilitates the installation and removal of the protective ring by personnel.

When the anti-collision plate 4 comes into contact with an object, the first conductive block 501 and the second conductive block 502 on one side of the contact plate 5 come into contact with a set of first conductive plates 601 and second conductive plates 605, respectively. The current on the first conductive plate 601 flows into the second conductive plate 605 through the contact plate 5, so that the first wire 6 and the second wire 604 form a closed loop through the conductive component. The controller 7 controls the cutter 1 to stop moving, thereby avoiding a large impact between the cutter 1 and the external object.

The second conductive ring 606 is connected to multiple sets of second conductive plates 605 through the conductive posts 602, so that the current on the second conductive plates 605 can flow into the second conductive ring 606 through the conductive posts 602.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The first conductive ring 603 is connected to the first wire 6, and the second conductive ring 606 is connected to the second wire 604. The first wire 6 is connected to the power supply.

The first conductive block 501 and the second conductive block 502 are both set as right-angled sectors, and the ends of the first conductive block 501 and the second conductive block 502 are connected. When the protective ring 2 moves to the inner end of the protective ring 2, the first conductive block 501 and the second conductive block 502 on one side of the contact plate 5 come into contact with a set of first conductive plates 601 and second conductive plates 605 respectively, so that the current in the first conductive plate 601 flows into the second conductive plate 605 through the first conductive block 501 and the second conductive block 502.

Figure 4 A spring 402 is sleeved on the outer wall of the connecting column 401, and the ends of the spring 402 are connected to the protective ring 2 and the anti-collision plate 4 respectively. When the anti-collision plate 4 collides with an object, the anti-collision plate 4 compresses and contracts the spring 402. When the anti-collision plate 4 is separated from the contact of the object, the spring 402 pushes the anti-collision plate 4 to reset.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 and Figure 2 The top of the cutter 1 is connected to an optical cable 101, and the bottom of the cutter 1 is equipped with a laser head 103.

The controller 7 is connected to a power source, and the controller 7 is internally connected to the first wire 6 and the second wire 604. The first wire 6 is connected to the positive terminal of the power source. Because the first conductive plate 6... 01 is connected to the first conductive coil 603 through the conductive post 602, so that current flows through the first conductive plate 601. The current on the first conductive plate 601 flows into the second conductive plate 605 through the first conductive block 501 and the second conductive block 502 on one side of the contact plate 5. The current on the second conductive plate 605 then flows into the second conductive coil 606 through the conductive post 602. Since the end of the second conductive coil 606 is connected to the second wire 604, the first wire 6 and the second wire 604 form a closed loop. The controller 7 controls the cutter 1 to stop moving.
