Technical Field

[0001] The present invention relates to the technical field of laser cutting assistance for metal materials, and particularly relates to a laser cutting assistance positioning mechanism for metal materials. Background Art

[0002] In the field of modern industrial manufacturing, the laser cutting technology for metal materials is widely used in many industries such as aerospace, automobile manufacturing, and machining due to its advantages of high precision, high speed, and high flexibility. However, in the actual laser cutting process, accurate positioning has always been a key problem to be solved urgently.

[0003] The existing laser cutting positioning methods for metal materials have many drawbacks. Traditional positioning methods often rely on manual operation. When facing metal materials of different specifications, operators need to spend a lot of time and effort to adjust the position of the materials to ensure their precise correspondence with the cutting area. This method is not only inefficient but also easily affected by human factors, resulting in low positioning accuracy and thus affecting the cutting quality. In addition, manual operation increases labor costs and reduces the production efficiency of enterprises. Therefore, we propose a laser cutting assistance positioning mechanism for metal materials to solve the above problems. Summary of the Invention

One end of the clamping mechanism is connected to a jet structure. A high-pressure gas transmission structure is installed on one side of the upper end of the moving plate. The high-pressure gas transmission structure is connected to the jet structure.

[0006] Preferably, the buffer mechanism includes a support frame fixed to the lower end of the bearing platform. A hydraulic damper is connected to the middle of the lower end of the support frame. Four bearing tubes are arranged at the four corners of the lower end of the support frame. Four vertical rods are fixed to the four corners of the lower end of the support frame. One vertical rod on the same side penetrates through one bearing tube on the same side. A spring is sleeved on the vertical rod. The upper end of the spring abuts against the lower end of the support frame, and the lower end of the spring abuts against the upper end of the bearing tube.

[0007] Preferably, the lifting mechanism includes a second servo motor installed at one side of the inner bottom of the carrier table. The end of the output shaft of the second servo motor is connected to a reduction box. The upper end of the reduction box is connected to a threaded sleeve through a coupling. The upper end of the threaded sleeve is screwed with a stud. The upper end of the stud penetrates through the side wall of the carrier table and is fixed to the lower end of the support plate. Both sides of the lower end of the support plate are fixed with guide rods. The guide rods penetrate through the side wall of the carrier table and extend into the carrier table.

[0008] Preferably, two sliders are fixed to both sides of the lower end of the moving plate. Guide rails are fixed to both sides of the upper end of the support plate. The two sliders on the same side are clamped on one guide rail on the same side.

[0009] Preferably, the adjusting mechanism includes a fixing plate fixed to one side of the support plate. A hydraulic cylinder is installed on one side of the fixing plate. The piston rod of the hydraulic cylinder penetrates through the fixing plate and is fixed to one side of the lower end of the moving plate.

[0010] Preferably, the reciprocating movement mechanism includes two connecting rods rotatably connected between the opposite side walls in the carrier box. Gears are fixedly sleeved on both sides of the connecting rods. A chain is meshed between the two gears on the same side. A first servo motor is installed on one side in the carrier box. The output shaft of the first servo motor is connected to one end of one of the connecting rods.

[0011] Preferably, the clamping mechanism includes a nozzle fixed to the upper ends of the two chains. Four moving blocks are equally spaced and fixed to one side of the nozzle. Four moving grooves corresponding to the moving blocks are equally spaced on the bottom of the carrier box. Four openings corresponding to the moving grooves are equally spaced on the upper end of the carrier box. The upper end of one moving block on the same side penetrates through one opening on the same side and extends to the upper end of the carrier box. The lower end of one moving block on the same side is clamped in one moving groove on the same side. A clamping plate is fixed to the upper end of the moving block.

[0014] When the present invention performs cutting: 1.

Clamping Material: Start the reciprocating movement mechanism. The first servo motor drives the connecting rod to rotate. The gear on the connecting rod meshes with the chain, thereby causing the chain to move. The movement of the chain drives the nozzle and the moving block connected to the nozzle to move in the moving groove, and then makes the clamping plate move towards the baffle, realizing the clamping of the metal material. 3. Position Adjustment Left - right position adjustment: The adjusting mechanism starts to work. The piston rod of the hydraulic cylinder expands and contracts, pushing the moving plate to slide left and right on the support plate through the slider and guide rail, thereby precisely adjusting the left - right position of the metal material to make it correspond to the cutting position. Up - down position adjustment: The lifting mechanism comes into play. The output shaft of the second servo motor drives the reduction gearbox to work. The reduction gearbox drives the threaded sleeve to rotate. The threaded sleeve is in threaded fit with the stud, causing the stud to move up and down, and then driving the support plate and the metal material placed on it to make up - down adjustment. 4. Cutting and Residue Cleaning: During the laser cutting process, the high - pressure gas supply structure starts to work. The air pump transports high - pressure gas through the hose to the nozzle, and then sprays it out from the spray holes through the gas transmission channel in the moving block, blowing away the residues generated by cutting, ensuring the smooth progress of the cutting process. 5. Stable Support: During the entire cutting process, the buffer mechanism provides stable support for the equipment. The hydraulic dampers and springs at the lower end of the support frame work together to absorb and buffer the vibrations and impact forces generated during cutting, ensuring the stability of the equipment and the cutting accuracy.

[0015] The present invention has the following advantages: 1. The auxiliary positioning mechanism realizes the automatic clamping and position adjustment of the metal material, eliminating the need for manual operation, greatly shortening the positioning time, and improving the working efficiency of laser cutting. 2. The setting of the buffer mechanism effectively absorbs and buffers the vibrations and impact forces during cutting, ensures the stability of the equipment, and extends the service life of the equipment. 3. Blowing away the residues generated by cutting reduces material waste and the defective rate, further reducing production costs and improving product quality. 4. Through the combination of multiple clamping plates and baffles, clamping of metal materials of different specifications can be achieved, and the stability and firmness of the clamping can be ensured. 5. Precise up - down and left - right position adjustments can be made, ensuring the accurate correspondence between the metal material and the cutting position, and improving the cutting accuracy. In summary, the present invention realizes the automatic clamping and position adjustment of metal materials, without manual operation, greatly shortening the positioning time, improving the working efficiency of laser cutting. At the same time, it can clamp metal materials of different specifications, and can ensure the stability and firmness of clamping. In addition, precise height and left-right position adjustment can be carried out to ensure the accurate correspondence between the metal material and the cutting position, improving the cutting accuracy.
