Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a tube laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Existing laser cutting machines typically clamp only one end of the tube during cutting, leaving the other end free. During the cutting process, due to the high energy of the laser beam, the tube may shift due to thermal deformation or mechanical vibration, resulting in a decrease in cutting accuracy. Furthermore, for tubes that require rotational cutting, existing equipment often relies on manual adjustment of the tube angle, which is inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide a tube laser cutting machine to solve the problems mentioned in the background art. In the case of existing laser cutting machines, when cutting, they usually only clamp one end of the tube while the other end is in a free state. During the cutting process, due to the high energy of the laser beam, the tube will shift due to thermal deformation or mechanical vibration, resulting in a decrease in cutting accuracy. Furthermore, for tubes that need to be rotated for cutting, existing equipment often relies on manual adjustment of the tube angle, which is inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tube laser cutting machine, comprising a worktable and a clamping part:

[0006] The workbench has a frame at the top and a laser cutting head at the bottom. A clamping part is located at the top of the workbench and has a rotating frame a on the top of the workbench. Rollers a are horizontally rotatable inside the rotating frame a. A rotating frame b is located at the top of the workbench and has rollers b horizontally rotatable inside the rotating frame b. Rollers a and b abut against the bottom of the tube. A support frame is located at the top of the workbench and a lifting frame is vertically slidable inside the support frame. Two rollers c are rotatably mounted at the bottom of the lifting frame and abut against the top of the tube. Roller a rotates to drive the tube to rotate.

[0007] By adopting the above technical solution, the pipe can be stably clamped using rollers a, b, and two rollers c. The rotation of roller a drives the pipe to rotate, enabling the laser cutting head to perform circumferential cutting on the pipe, thus improving the comprehensiveness and efficiency of the cutting.

[0008] Preferably, the worktable also has a chute formed on the top of the worktable, and a collection box is slidably disposed inside the chute, which is located directly below the laser cutting head to collect waste.

[0009] By adopting the above technical solution, when the laser cutting head cuts the pipe, the generated waste chips can fall directly into the collection box, avoiding the waste chips from scattering on the worktable and keeping the worktable clean.

[0010] Preferably, the clamping part has a power shaft that is laterally rotatable inside the worktable, and a motor is provided at one end of the worktable, the output end of which is connected to the power shaft.

[0011] By adopting the above technical solution, an electric motor can be used to provide rotational power for the drive shaft.

[0012] Preferably, the clamping part also has a power tooth disposed on the side of the power shaft, and a transmission tooth b is rotatably disposed inside the worktable, which meshes with the power tooth.

[0013] By adopting the above technical solution, the rotational power of the power shaft can be transmitted through the meshing of the power gear and the transmission gear b, thereby achieving effective power transmission.

[0014] Preferably, the clamping part also has a transmission tooth a disposed at one end of the roller a, the transmission tooth a being engaged with the transmission tooth b.

[0015] By adopting the above technical solution, the power received by the transmission gear b can be transmitted to the roller a through the transmission gear a, thereby enabling the roller a to rotate and ultimately drive the pipe to rotate.

[0016] Preferably, there are two rollers a, which are located at both ends of the pipe, and there are two rollers b, which correspond to the positions of the two rollers a and are at the same height.

[0017] By adopting the above technical solution, the pipe can be supported and clamped from both ends, making the pipe more stable during the cutting process, avoiding shaking or displacement, and ensuring the accuracy and quality of the cutting.

[0018] Preferably, the clamping part also has a limiting groove formed on the side of the support frame, and a limiting block is provided on the side of the lifting frame. The limiting block is embedded in the limiting groove and is vertically slidably connected to the support frame.

[0019] By adopting the above technical solution, the lifting movement of the lifting frame can be limited and guided, ensuring that the lifting frame slides smoothly in the vertical direction, preventing it from deviating or shaking during the sliding process, and ensuring that the roller c can accurately contact the top of the pipe and apply appropriate pressure.

[0020] Preferably, the clamping part also has a lead screw nested and threaded to the top of the support frame, the top of the lead screw is provided with a rotating handle, the top of the lifting frame is provided with a rotating groove, and the bottom of the lead screw is embedded in the rotating groove and rotatably connected to the lifting frame.

[0021] By adopting the above technical solution, the screw can be rotated by turning the handle. Since the screw and the support frame are connected by a thread, the rotation of the screw will be converted into the vertical lifting motion of the lifting frame, thereby making it easy to adjust the height of the roller c to meet the clamping requirements of pipes with different diameters.

[0022] Preferably, the surfaces of rollers a, b and c are all fitted with rubber sleeves with anti-slip textures.

[0023] By adopting the above technical solution, the friction between rollers a, b, and c and the surface of the pipe can be increased, preventing slippage during the rotation of the pipe and ensuring that the pipe can stably follow the rotation of the rollers.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: by providing a clamping part, the pipe can be stably clamped by rollers a, b and two rollers c, and the rotation of roller a drives the pipe to rotate, so that the laser cutting head can perform circumferential cutting on the pipe, improving the comprehensiveness and efficiency of the cutting; the two rollers a can support and clamp the pipe from both ends, making the pipe more stable during the cutting process, avoiding shaking or deviation, and ensuring the accuracy and quality of the cutting.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a tube laser cutting machine, including a worktable 1 and a clamping part 2.

[0035] A frame 101 is installed on the top of the worktable 1, and a laser cutting head 102 for cutting is installed at the bottom of the frame 101. The working principle of the laser cutting head 102 is that the working substance of the laser generator forms a laser beam in the optical resonant cavity under the excitation of the pump source energy. After being transmitted and focused by the optical system, the high-energy-density laser beam irradiates the material, causing it to heat up rapidly, melt, and vaporize. At the same time, the auxiliary gas blows away the molten slag. The above is the prior art and will not be described in detail below. The cutting head moves along a preset path to complete the material cutting. The worktable 1 also has a slide 103 opened on the top of the worktable 1. A collection box 104 is slidably installed inside the slide 103. The collection box 104 is located directly below the laser cutting head 102 to collect waste chips. When the laser cutting head 102 cuts the tube, the waste chips generated can fall directly into the collection box 104, avoiding the waste chips from scattering on the worktable 1 and keeping the worktable 1 clean.

[0036] The clamping part 2 is located on the top of the worktable 1. The clamping part 2 has a rotating frame a201 located on the top of the worktable 1. A roller a202 is horizontally rotatably arranged inside the rotating frame a201. A rotating frame b208 is located on the top of the worktable 1. A roller b209 is horizontally rotatably arranged inside the rotating frame b208. Rollers a202 and b209 abut against the bottom of the tube. A support frame 210 is located on the top of the worktable 1. A lifting frame 212 is vertically slidably arranged inside the support frame 210. Two rollers c215 are rotatably arranged at the bottom of the lifting frame 212. The two rollers c215 abut against the top of the tube. The rotation of roller a202 drives the tube to rotate. The tube can be stably clamped by rollers a202, b209 and c215. The rotation of roller a202 drives the tube to rotate, so that the laser cutting head 102 can perform circumferential cutting on the tube, improving the comprehensiveness and efficiency of the cutting.

[0037] Example 2

[0038] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a tube laser cutting machine, including a clamping part 2, rollers a202 and a lifting frame 212.

[0039] A power shaft 205 is rotatably installed inside the worktable 1. A motor 207 is installed at one end of the worktable 1. The output end of the motor 207 is connected to the power shaft 205, so that the motor 207 can provide rotational power to the power shaft 205.

[0040] A power gear 206 is provided on the side of the power shaft 205, and a transmission gear b204 is provided inside the worktable 1. The transmission gear b204 meshes with the power gear 206, so that the rotational power of the power shaft 205 can be transmitted through the meshing of the power gear 206 and the transmission gear b204, thereby realizing the effective transmission of power.

[0041] A transmission tooth a203 is provided at one end of the roller a202. The transmission tooth a203 meshes with the transmission tooth b204, and can transmit the power received by the transmission tooth b204 to the roller a202 through the transmission tooth a203, so that the roller a202 can rotate, and finally drive the pipe to rotate.

[0042] There are two rollers a202, located at both ends of the pipe. There are also two rollers b209, which correspond to the positions of the two rollers a202 and are at the same height. They can support and clamp the pipe from both ends, making the pipe more stable during the cutting process, avoiding shaking or deviation, and ensuring the accuracy and quality of the cutting.

[0043] A limiting groove 211 is provided on the side of the support frame 210, and a limiting block 214 is provided on the side of the lifting frame 212. The limiting block 214 is embedded in the limiting groove 211 and is vertically slidably connected to the support frame 210. This can limit and guide the lifting movement of the lifting frame 212, ensuring that the lifting frame 212 slides smoothly in the vertical direction, preventing it from deviating or shaking during the sliding process, and ensuring that the roller c215 can accurately contact the top of the pipe and apply appropriate pressure.

[0044] A lead screw 216 is vertically threaded and nested at the top of the support frame 210. A handle 217 is provided at the top of the lead screw 216. A rotating groove 213 is provided at the top of the lifting frame 212. The bottom of the lead screw 216 is embedded in the rotating groove 213 and is rotatably connected to the lifting frame 212. The lead screw 216 can be rotated by rotating the handle 217. Since the lead screw 216 is threadedly connected to the support frame 210, the rotation of the lead screw 216 will be converted into the vertical lifting motion of the lifting frame 212, thereby facilitating the adjustment of the height of the roller c215 to meet the clamping requirements of pipes with different diameters.

[0045] Rollers a202, b209, and c215 are all fitted with rubber sleeves with anti-slip textures. This increases the friction between rollers a202, b209, and c215 and the pipe surface, preventing slippage during pipe rotation and ensuring the pipe can stably follow the rollers.

[0046] Working principle: First, the pipe to be cut is placed between rollers a202, b209, and c215. Since rollers a202 and b209 are each provided in pairs and positioned at the same height, they can support the pipe from both ends. Then, by rotating the handle 217, the lead screw 216 is rotated. Because the lead screw 216 is threadedly connected to the support frame 210, the rotation of the lead screw 216 is converted into the vertical lifting motion of the lifting frame 212. The limiting block 214 on the side of the lifting frame 212 is embedded in the limiting groove 211 on the side of the support frame 210, thus controlling the vertical lifting motion of the lifting frame 212. The lifting motion of roller 202 is limited and guided to ensure smooth vertical sliding, allowing roller c215 to descend until it abuts against the top of the pipe. This provides stable clamping of the pipe using rollers a202, b209, and c215, adaptable to clamping requirements of pipes with different diameters. Next, motor 207 is started, and its output drives the power shaft 205 to rotate. The power gear 206 on the side of the power shaft 205 rotates accordingly. Since the transmission gear b204 meshes with the power gear 206, the rotational power of the power shaft 205 is transmitted through the power gear 206 and the transmission gear b204. The meshing transmission is transmitted to the transmission gear b204. Since the transmission gear a203 meshes with the transmission gear b204, the power received by the transmission gear b204 is transmitted to the roller a202 through the transmission gear a203, causing the roller a202 to rotate and ultimately drive the pipe to rotate. Simultaneously, the surfaces of rollers a202, b209, and c215 are all nested with rubber sleeves with anti-slip textures, increasing friction with the pipe surface and preventing slippage during pipe rotation. This ensures the pipe can stably follow the rollers' rotation. Finally, the laser cutting head 102 is activated, and the laser... The working medium of the generator forms a laser beam in the optical resonant cavity under the excitation of the pump source energy. After being transmitted and focused by the optical system, the high-energy-density laser beam irradiates the tube, causing it to heat up rapidly, melt, and vaporize. At the same time, the auxiliary gas blows away the molten slag. The cutting head moves along a preset path to complete the cutting of the tube. During the cutting process, the waste generated will fall directly into the collection box 104 located directly below the laser cutting head 102, preventing the waste from scattering on the worktable 1 and keeping the worktable 1 clean. Furthermore, as the tube rotates, the laser cutting head 102 can perform circumferential cutting on the tube, improving the comprehensiveness and efficiency of the cutting.
