Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting equipment, in particular to a clamp for a laser cutting machine. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, the 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 cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] Laser cutting uses invisible light beams to replace traditional mechanical knives. It has the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs.

[0004] The laser cutting machine in the prior art needs to use a matching clamp during the cutting process to clamp the workpiece to be cut to prevent the workpiece from moving and causing cutting errors. However, when the laser cutting machine clamp in the prior art cuts the metal workpiece, the workpiece is only fixed by a clamping plate. When clamping an irregularly shaped metal workpiece, the workpiece needs to be adjusted to a direction that is conducive to clamping, which increases the extra workload and reduces the cutting efficiency of the laser cutting machine.

[0037] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] like Figure 1~Figure 4As shown, this embodiment proposes a clamp for a laser cutting machine, including a support seat 1, and also includes a mounting plate 2, a clamping mechanism, a clamping frame 3, an adjustment mechanism, a bearing tray 4 and a moving component. There are two mounting plates 2, and the two mounting plates 2 are fixedly connected to the support seat 1. The clamping mechanism is installed on the support seat 1. There are two clamping frames 3, and the two clamping frames 3 are slidably connected to the support seat 1. The adjustment mechanism is installed at the bottom end of the support seat 1, the bearing tray 4 is rotatably connected to the support seat 1, and the moving component is installed at the bottom end of the support seat 1. When clamping the workpiece, the workpiece is first placed on the bearing tray 4, and then the clamping mechanism preliminarily fixes the workpiece, the adjustment mechanism is started, the angle of the irregularly shaped workpiece is adjusted, and the most stable clamping position is found. Finally, the laser cutting machine is used for cutting. It also has a stable clamping effect for irregularly shaped workpieces, and the clamping speed is fast, which improves the work efficiency of the cutting work.

[0039] Among them, the clamping mechanism includes a clamping roller 5, a locking handle 6 and an electric cylinder 7. There are multiple clamping rollers 5, and the multiple clamping rollers 5 are rotatably connected in the two clamping frames 3. There are multiple locking handles 6, and a locking handle 6 is provided at one end of each clamping roller 5. There are six electric cylinders 7, and three electric cylinders 7 are fixedly connected to each mounting plate 2. The output ends of the six electric cylinders 7 are fixedly connected to the two clamping frames 3. The clamping roller 5 is rotatably connected and can be rotated freely in the clamping frame 3. When the workpiece is placed on it, the workpiece rotates, driving the clamping roller 5 to rotate. When the clamping roller 5 encounters irregular edges and corners on the workpiece, the clamping roller 5 will idle. At this time, the electric cylinder 7 is started to clamp the workpiece thoroughly. The clamping of irregular-shaped workpieces is more stable, and the clamping speed will not be affected too much.

[0040] Secondly, the adjustment mechanism includes a mounting groove, an electromagnet 9 and a motor 10. The mounting groove is opened on the support seat 1. Four electromagnets 9 are provided. The four electromagnets 9 are fixedly connected to the bottom end of the support tray 4. The four electromagnets 9 are slidably connected in the mounting groove. The motor 10 is fixedly connected to the bottom end of the support seat 1. The output end of the motor 10 is connected to the support tray 4. The adjustment mechanism is used to drive the workpiece to rotate and adjust the direction. The motor 10 is started first, and the motor 10 drives the support plate to rotate. The electromagnet 9 is started to adsorb the metal workpiece. The electromagnet 9 can also prevent the workpiece from shifting during cutting to a certain extent. After the cutting is completed, the electromagnet 9 is turned off, and the cut workpiece can be removed, which is efficient.

[0041] Again, the moving component includes a fixed plate 11, a slider 12 and a screw 13. There are four fixed plates 11, which are fixedly connected to the four corners of the support base 1. There are two sliders 12, which are fixedly connected to both sides of the support base 1. There are multiple screws 13, and each fixed plate 11 is provided with four screws 13. The moving mechanism allows the clamp to be freely moved and fixed on the laser cutting machine, which is more convenient when clamping some overly long or overly large workpieces, thereby improving the applicability of the clamp.

[0042] Among them, the number of clamping rollers 5 in the two clamping frames 3 is different. The number of clamping rollers 5 in one clamping frame 3 is less than that in the other clamping frame 3. Different numbers of clamping frames 3 can make the spacing between the clamping rollers 5 larger or smaller, and the edges at different angles can be stably clamped, the clamping effect is better, and the applicability of the clamp is improved.

[0043] Finally, four through holes 14 are provided on the supporting tray 4, and one end of the four electromagnets 9 with magnetic force is fixedly connected in the through holes 14. The through holes 14 enable the electromagnets 9 to directly contact the metal workpiece, and the magnetic force is stronger.

[0044] In this embodiment, the workpiece is placed on the supporting plate 4 between the two clamping frames 3, the electric cylinder 7 is started, driving the two clamping frames 3 to initially clamp the workpiece, and then the motor 10 is started to drive the supporting plate 4 and the workpiece thereon to rotate, and the clamping roller 5 is used to find the clamping position most suitable for the workpiece. At this time, the locking handle 6 is tightened to lock the clamping roller 5, and the electric cylinder 7 is started to clamp the workpiece. The clamping roller 5 can stably clamp the irregular workpiece.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
