Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine equipment technology, and in particular to a laser cutting machine with a multi-dimensional cutting head adjustment mechanism. Background Technology

[0002] As an advanced processing equipment, laser cutting machines use high-energy-density laser beams to irradiate the surface of workpieces, causing the material to melt or vaporize instantly, thereby achieving high-precision cutting of various materials. They have the advantages of fast cutting speed, good cut quality, and small heat-affected zone, and are widely used in many fields such as automobile manufacturing, electronic equipment production, aerospace, and precision machining. In these industries, laser cutting machines can meet the diverse processing needs of workpieces with different shapes and materials, greatly improving production efficiency and product quality.

[0003] Existing laser cutting machines with multi-dimensional cutting head adjustment mechanisms can, to some extent, meet the need for flexible adjustment of the cutting head position. Through motor drive and complex transmission structure, the cutting head can move precisely in multiple dimensions, avoiding the tedious operation of frequently changing equipment or tooling when cutting workpieces of different shapes. However, there are shortcomings in the crucial aspect of quickly locking and releasing the cutting head position. Currently, commonly used locking devices are mostly simple bolt tightening structures. After the cutting head is adjusted to the correct position, the operator needs to manually tighten the bolts with tools to fix the cutting head position. However, this bolt tightening method makes it difficult to ensure that the applied torque is uniform each time during operation. Moreover, after long-term and frequent use, the bolts are prone to wear and loosening. This not only causes the cutting head to shift position due to vibration during the cutting process, affecting the cutting accuracy, but also makes the bolt disassembly and installation process cumbersome and time-consuming when the cutting head position needs to be readjusted, thus reducing the overall processing efficiency of the equipment. Utility Model Content

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.

[0032] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a laser cutting machine with a multi-dimensional cutting head adjustment mechanism, including a control box 1 and a laser cutting head 13. A servo motor 3 is fixedly connected to the bottom of the control box 1, and a U-shaped block 4 is fixedly connected to the output end of the servo motor 3. Starting the servo motor 3 can drive the U-shaped block 4 to rotate. An electric telescopic rod 5 is fixedly connected to the front side of the outer wall of the U-shaped block 4, and a rack 6 is fixedly connected to one end of the electric telescopic rod 5. Starting the electric telescopic rod 5 can drive the rack 6 to rotate. A hollow block 8 is rotatably connected to the inner wall of the U-shaped block 4. A gear 7 is fixedly connected to the front side of the hollow block 8 through the U-shaped block 4. The gear 7 meshes with the rack 6, utilizing the rack 6 and... The meshing relationship of gear 7 drives gear 7 to rotate, which in turn drives hollow block 8 to rotate together. A grooved block 12 is fixedly connected to the left side of laser cutting head 13. A T-shaped block 9 is provided on the inner wall of grooved block 12. T-shaped block 9 is engaged with grooved block 12. A stud 10 is fixedly connected to the top of T-shaped block 9. A nut 11 is threadedly connected to the outer wall of stud 10. First, rotate nut 11 to remove it from above stud 10. Then, remove T-shaped block 9 from above grooved block 12 to remove laser cutting head 13. A quick adjustment mechanism 2 is provided on the right side of hollow block 8. Quick adjustment mechanism 2 is used to reduce vibration during operation and allows for fine adjustment.

[0033] Specifically, starting the servo motor 3 can drive the U-shaped block 4 to rotate, and starting the electric telescopic rod 5 can drive the rack 6 to rotate. Utilizing the meshing relationship between the rack 6 and the gear 7, the gear 7 is driven to rotate, which in turn drives the hollow block 8 to rotate as well. When it is necessary to remove the laser cutting head 13, simply rotate the nut 11 first to remove the nut 11 from above the stud 10, and then remove the T-shaped block 9 from above the grooved locking block 12, thereby removing the laser cutting head 13 for inspection and maintenance.

[0034] Reference Figure 1 , Figure 2 and Figure 5The quick adjustment mechanism 2 includes an anti-slip cylinder 201, which is fixedly connected to the right side of the hollow block 8. A hollow sliding disk 202 is rotatably connected to the inner wall of the anti-slip cylinder 201. A rotating disk 204 is fixedly connected to the left side of the T-shaped block 9. An anti-slip cylinder 203 rotates above the rotating disk 204 and can be adjusted. An anti-slip cylinder 203 is rotatably connected to the outer wall of the rotating disk 204. A limit post 205 is fixedly connected to the left side of the rotating disk 204. The limit post 205 is slidably connected to the inner wall of the hollow sliding disk 202. A buffer spring 206 is fixedly connected to the right side of 202. The right side of the buffer spring 206 is fixedly connected to the rotating disk 204. When the buffer spring 206 is reset, the anti-slip cylinder 203 and the anti-slip cylinder 201 are no longer firmly attached together. Then, the laser cutting head 13 is rotated for adjustment. Electromagnetic blocks 207 are fixedly connected to the front and rear sides of the outer wall of the anti-slip cylinder 201. When the electromagnetic blocks 207 are activated, the anti-slip cylinder 201 is given a strong magnetic ability. At this time, the anti-slip cylinder 203 will be firmly attached to the top of the anti-slip cylinder 201.

[0035] Specifically, during use, by activating the electromagnetic block 207, the anti-slip cylinder 1 201 is given a strong magnetic ability, which causes the anti-slip cylinder 203 to firmly adhere to the top of the anti-slip cylinder 1 201 and compress the buffer spring 206, thus making the whole thing firmly together. When a slight adjustment is needed during use, simply turn off the electromagnetic block 207. At this time, the anti-slip cylinder 1 201 loses its strong magnetic ability, and then, under the reset of the buffer spring 206, the anti-slip cylinder 203 and the anti-slip cylinder 1 201 are no longer firmly adhered together. Then, rotate the laser cutting head 13 to make adjustment, so that the anti-slip cylinder 203 rotates above the rotating disk 204. After the adjustment is completed, activate the electromagnetic block 207 to make the anti-slip cylinder 1 201 regain its strong magnetic ability, and then fix the adjusted angle.

[0036] Reference Figure 1 , Figure 3 and Figure 4 A nameplate 14 is fixedly connected to the center of the front side of the control box 1, and a warning sign block 15 is fixedly connected to the bottom of the front side of the control box 1. The nameplate 14 can record the model and basic information of the equipment, and the warning sign block 15 can easily remind users of precautions during use. An L-shaped plate 16 is fixedly connected to the top left side of the outer wall of the control box 1. Multiple sliding wheels 17 are rotatably connected to the inner wall of the L-shaped plate 16. The L-shaped plate 16 can provide installation space for the sliding wheels 17, and the sliding wheels 17 can facilitate the sliding of the control box 1. A limit strip 18 is fixedly connected to the bottom left side of the control box 1, and a warning light 19 is fixedly connected to the top of the control box 1. The limit strip 18 can limit the direction of its sliding, and the warning light 19 can remind the operator when a malfunction occurs.

[0037] Specifically, the nameplate 14 can record the equipment model and basic information, the warning sign block 15 can remind users of precautions during use, the L-shaped plate 16 can provide installation space for the sliding wheel 17 and the sliding wheel 17 can facilitate the sliding of the control box 1, the limit strip 18 can limit the direction of its sliding, and the warning light 19 can remind the operator when a malfunction occurs.

[0038] Reference Figure 1 , Figure 2 and Figure 6 A hole block 20 is fixedly connected to the front side of the laser cutting head 13. A laser sensor 21 is slidably connected to the inner wall of the hole block 20. A fixing bolt 22 is threadedly connected to the front side of the hole block 20. The hole block 20 can hold the laser sensor 21, and the fixing bolt 22 can easily fix the laser sensor 21 to the hole block 20. An adjustment knob 23 is rotatably connected to the right side of the outer wall of the laser cutting head 13. A triangular indicator block 24 is fixedly connected to the top right side of the adjustment knob 23. Multiple scale lines 25 are opened on the right side of the laser cutting head 13. The adjustment knob 23 can adjust its power. The triangular indicator block 24 and the scale lines 25 can easily and intuitively show the current power value of the laser cutting head 13. A limit ring 26 is fixedly connected to the left side of the U-shaped block 4. The outer wall of the limit ring 26 is slidably connected to the control box 1. The limit ring 26 can easily limit the sliding of the U-shaped block 4 above the control box 1.

[0039] Specifically, the laser sensor 21 can be placed through the hole block 20, and the laser sensor 21 can be easily fixed on the hole block 20 through the fixing bolt 22. Its power can be adjusted by adjusting the knob 23. The current power value of the laser cutting head 13 can be easily and intuitively known through the triangular indicator block 24 and the scale line 25. The limit ring 26 can easily limit the sliding of the U-shaped block 4 above the control box 1.

[0040] Working principle: By starting the servo motor 3, the U-shaped block 4 can be rotated. After starting the electric telescopic rod 5, the rack 6 rotates accordingly. With the meshing mechanism of the rack 6 and the gear 7, the gear 7 is rotated, which in turn drives the hollow block 8 to rotate synchronously. If the laser cutting head 13 needs to be disassembled, the nut 11 should be rotated first to remove it from the stud 10. Then, the T-shaped block 9 should be removed from the grooved block 12 to facilitate the inspection and maintenance of the laser cutting head 13.

[0041] Furthermore, through the rapid adjustment mechanism 2, during operation, activating the electromagnetic block 207 will give the anti-slip cylinder one 201 a strong magnetism, which will cause the anti-slip cylinder two 203 to be tightly attracted to the top of the anti-slip cylinder one 201 and apply pressure to the buffer spring 206, thereby ensuring the stability of the overall structure. When fine adjustment is required, closing the electromagnetic block 207 will cause the anti-slip cylinder one 201 to lose its magnetism, and the buffer spring 206 will then reset, releasing the attraction between the anti-slip cylinder two 203 and the anti-slip cylinder one 201. At this time, the rotatable laser cutting head 13 can be rotated for adjustment, allowing the anti-slip cylinder two 203 to rotate freely on the rotating disk 204. After adjustment, the electromagnetic block 207 is activated again to restore the magnetism of the anti-slip cylinder one 201, thereby locking the adjusted angle.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
