Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and in particular to a high-efficiency and precision laser cutting processing device for metal materials. Background Art

[0002] Laser cutting is a technology that uses a laser to cut materials and is commonly used in industrial manufacturing applications. The working principle of laser cutting generally involves guiding the output of a high-power laser through optical devices. The laser optical system and the numerical control system are used to guide the material or the generated laser beam. The laser beam is focused and aligned with the material, and then the material is melted, burned, evaporated, or blown away by a gas jet, leaving an edge with a high-quality surface finish.

[0003] In a Chinese patent with the publication number CN115283855A, a laser cutting mechanical device for metal material processing is disclosed, which includes an equipment frame, a side limiting mechanism, a double-axis conveying mechanism, and a metal material to be cut. The equipment frame includes a first frame, a second frame, and a third frame. In this laser cutting mechanical device for metal material processing, by turning the knob to drive the corresponding threaded lead screw to rotate, the limiting plate assembly screwed to the threaded lead screw is driven to slide along the lower surface of the top plate, so that the position of the limiting plate assembly can be adjusted. By adjusting the positions of the respective limiting plate assemblies, the first limiting plate is respectively attached to the side surface of the metal material to be cut without applying pressure to the metal material to be cut, thereby limiting it during the conveying process of the metal material to be cut, enabling it to be conveyed in a straight direction to the working area of the cutting mechanism, effectively avoiding the inclination of the metal material to be cut during the conveying process, and thus improving the cutting accuracy.

[0004] Although the above device can accurately cut metal materials of various sizes through various structures, in reality, after the metal material is cut, there are many burrs remaining at the cutting area. When the staff handles the cut metal material, it is extremely easy to cause the risk of cuts, and subsequent deburring is also required, resulting in low processing efficiency of the metal material.

[0005] Therefore, those skilled in the art have proposed a high-efficiency and precision laser cutting processing device for metal materials. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Through the combined use of the moving mechanism and the inner support mechanism, the present invention realizes the inner support and fixation of the workpiece to be processed. The moving mechanism drives the first threaded clamping rod and the second threaded clamping rod to rotate through the stepping motor, so that the movable block drives the connecting rod to abut against both ends of the workpiece to be processed. The inner support mechanism drives the screw rod to rotate through the second stepping motor, so that the movable cylinder moves, and then through the first connecting rod and the second connecting rod, the movable plate two moves away from the screw rod until the silicone layer abuts against the inner wall of the workpiece to be processed, thus completing the inner support and fixation of the workpiece to be processed, providing a stable basis for subsequent operations such as cutting and grinding.

[0016] 2. Through the design of the cutting mechanism, the present invention realizes the efficient and precise cutting of the workpiece to be processed. After the cutting mechanism lowers the two arc-shaped half-circle plates on both sides to both sides of the workpiece to be processed through the first guiding rail, the third stepping motor drives the first double-headed threaded rod to rotate, causing the two movable plates on both sides to approach each other, and the arc-shaped half-circle plates surround the outside of the workpiece to be processed and close. Then, the driving motor drives the arc-shaped toothed plate to rotate, causing the laser head to rotate around the outer circumference of the workpiece to be processed. Thus, when the laser head is turned on, it can perform middle cutting around the workpiece to be processed.

[0017] 3. Through the combined use of the auxiliary mechanism and the grinding mechanism, the present invention realizes the automatic grinding of the cutting surface of the workpiece to be processed. The auxiliary mechanism drives the second double-headed threaded rod to rotate through the fourth stepping motor, causing the two movable plates on both sides to approach each other. Furthermore, through the linkage of the third connecting rod and the hinge, the two groups of workpieces to be processed after cutting are driven to move away from each other, and the cutting surfaces are all forward. The grinding mechanism moves the connecting frame to drive the electric push rod towards the workpiece to be processed after turning through the second guiding rail until the abrasive plate abuts against the cutting surface of the workpiece to be processed. Then, the telescopic end of the electric push rod reciprocates, which can drive the abrasive plate to grind the workpiece to be processed. This design avoids the cumbersome process of manual grinding, optimizes the production steps, and improves the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0040] Example 1:

[0042] As can be seen from the above, when the device is used, the workpiece 3 to be processed is first placed on the top of the conveying device 2, and the workpiece 3 to be processed is moved to the left by the conveying device 2 until the infrared sensor 4 senses that the workpiece 3 to be processed has arrived at the designated location, and the conveying device 2 stops transporting the workpiece 3 to be processed, and then the cylinder 5 is turned on, and the cylinder 5 drives the workpiece 3 to be processed to leave the conveying device 2 through the arc-shaped support plate 6, and then the inner support mechanisms 10 on both sides enter the interior of the workpiece 3 to be processed through the moving mechanism 9, and then the inner support mechanism 10 is used to internally support and fix the inner wall of the workpiece 3 to be processed, and the cylinder 5 drives the arc-shaped support plate 6 to reset, and then the cutting mechanism is driven by the guide rail 11. 12 is lowered to a suitable height, the cutting mechanism 12 is used to cut the workpiece 3 into two groups, and then the two groups of workpieces 3 to be processed are moved away from each other by the auxiliary mechanism 13 after cutting, so that the cutting surfaces of the two groups of workpieces 3 to be processed are both facing forward, and the grinding mechanism 16 is moved horizontally to a suitable position by the guide rail 15, and the grinding mechanism 16 grinds the cutting surfaces of the workpieces 3 to be processed which are divided into two groups. Finally, through the above steps, the two groups of workpieces 3 to be processed after cutting and grinding of the cutting surfaces are placed again on the conveying device 2, so as to avoid the need for manual grinding of the cut workpieces 3 to be processed, thereby optimizing the production steps.

[0043] Embodiment 2:

[0044] As attached Figure 3 To Attachment Figure 6As shown, this embodiment is basically the same as the previous embodiment, except that the moving mechanism 9 includes a threaded clamp rod 1 901 and a threaded clamp rod 2 902 which are respectively rotatably connected to the inner sides of two groups of movable plates 1 7, a slide groove 1 903 is provided on the outer sides of the two groups of movable plates 1 7, a slider 1 904 is slidably connected to the interior of the slide groove 1 903, a movable block 905 is fixedly connected to the outer side of the slider 1 904, the movable blocks 905 on both sides slide on the outer surfaces of the threaded clamp rod 1 901 and the threaded clamp rod 2 902 respectively, a connecting rod 906 is welded to the outer side of the movable block 905, a stepping motor 1 907 is fixedly installed on the outer side of one group of movable plates 1 7, the inner support mechanism 10 includes a mounting plate 1001 fixedly connected to the outer side of the connecting rod 906, and a The cylinder plate 1002 has a screw rod 1003 which is rotatably connected to the inside of the cylinder plate 1002. The outer surface of the screw rod 1003 is threadedly connected to a movable cylinder 1004. The outer circumference of the movable cylinder 1004 is equidistantly hinged with connecting rods 1005. The outer circumference of the cylinder plate 1002 is equidistantly hinged with connecting rods 1006. The connecting rods 1005 and the middle parts of the corresponding connecting rods 1006 are rotatably connected via a pin. The connecting rods 1005 and 1006 are hinged with movable plate 2 1007 on the side away from the screw rod 1003. The outer side of the movable plate 2 1007 is covered with a silicone layer 1008. A stepper motor 2 1009 is fixedly installed on the outer side of the mounting plate 1001. The output end of the stepper motor 1009 extends to the inner side of the mounting plate 1001 and is fixedly connected to the screw rod 1003.

[0045] As can be seen from the above, after the cylinder 5 drives the workpiece 3 to be processed to leave the conveying device 2 through the arc-shaped support plate 6, the stepper motor 1 907 is turned on, and the stepper motor 1 907 drives the threaded clamp rod 1 901 to rotate, and then drives the engaged threaded clamp rod 2 902 to rotate synchronously, and the threaded clamp rod 1 901 and the threaded clamp rod 2 902 drive the movable block 905 to slide along the slide groove 1 903 through the slider 1 904 until the connecting rod 906 and the two ends of the workpiece 3 to be processed are abutted, and then the stepper motor 2 1009 is turned on, and the stepper motor 2 1009 drives the screw rod 1003 to rotate, and the screw rod 1003 drives the movable cylinder 1004 to move, and then the movable plate 2 1007 is moved away from the screw rod 1003 through the connecting rod 1005 and the connecting rod 2 1006, until the entire silicone layer 1008 is abutted against the inner wall of the workpiece 3 to be processed.

[0046] Embodiment three:

[0047] As attached Figure 7 To Attachment Figure 8As shown in the figure, this embodiment is basically the same as the previous one. The difference is that the cutting mechanism 12 includes a support rod 1201 slidably connected inside the first guide rail 11. A first fixed plate 1202 is fixedly connected to the bottom of the support rod 1201. A first double-headed threaded rod 1203 is rotatably connected between the first fixed plate 1202 and the support rod 1201. A third stepping motor 1204 is fixedly installed on the outer side of the support rod 1201. The output end of the third stepping motor 1204 extends between the first fixed plate 1202 and the support rod 1201 and is fixedly connected to one end of the first double-headed threaded rod 1203. Two first slide rods 1205 are fixedly connected between the first fixed plate 1202 and the support rod 1201. The two first slide rods 1205 are symmetrically distributed on the opposite sides of the first double-headed threaded rod 1203. Movable plates three 1206 are threadedly connected to the opposite sides of the first double-headed threaded rod 1203. Arc-shaped half-circle plates 1207 are fixedly connected to the bottoms of the movable plates three 1206. A second chute 1208 is formed on the outer surface of the arc-shaped half-circle plate 1207. An arc-shaped toothed plate 1209 is slidably connected inside the second chute 1208. A second mounting plate 1212 is fixedly connected to the outer side of one arc-shaped half-circle plate 1207. A drive motor 1211 is fixedly installed on the top of the second mounting plate 1212. A gear 1210 is fixedly connected to the output end of the drive motor 1211. The gear 1210 is meshed with the arc-shaped toothed plate 1209. A follower plate 1213 is fixedly connected to the outer surface of the arc-shaped toothed plate 1209. A laser head 1214 is arranged on the outer side of the follower plate 1213.

[0048] As can be seen from the above, after the two arc-shaped half-circle plates 1207 are lowered to both sides of the workpiece 3 through the first guide rail 11, the third stepping motor 1204 is turned on. The third stepping motor 1204 drives the first double-headed threaded rod 1203 to rotate. Then, through the guiding of the two first slide rods 1205, the two movable plates three 1206 move closer to each other until the two arc-shaped half-circle plates 1207 move closer to each other, surround the outside of the workpiece 3 and close. And the overall diameter formed by the two arc-shaped half-circle plates 1207 is larger than that of the workpiece 3. Then, the drive motor 1211 is turned on. The drive motor 1211 drives the arc-shaped toothed plate 1209 to rotate. Then, the arc-shaped toothed plate 1209 on this side can enter the inside of the second chute 1208 of the other arc-shaped half-circle plate 1207, so that the laser head 1214 rotates around the outer circumference of the workpiece 3. Thus, by turning on the laser head 1214, the middle part of the workpiece 3 can be cut. After the cutting is completed, the arc-shaped toothed plates 1209 on each side are reset, and the third stepping motor 1204 rotates in the reverse direction and the first guide rail 11 makes the two arc-shaped half-circle plates 1207 move away from the workpiece 3.

[0049] Embodiment 4:

[0050] As shown in the append Figure 9 to the append Figure 10As shown in the figure, this embodiment is basically the same as the previous one, except that the auxiliary mechanism 13 includes two groups of second fixed plates 1301 welded to the front side of the frame plate 14. A double-headed threaded rod two 1302 is rotatably connected between the two groups of second fixed plates 1301. A fourth stepper motor 1303 is fixedly installed on the outside of one group of second fixed plates 1301. The output end of the fourth stepper motor 1303 extends between the two groups of second fixed plates 1301 and is fixedly connected to one end of the double-headed threaded rod two 1302. Two groups of second slide rods 1304 are fixedly connected between the two groups of second fixed plates 1301. The two groups of second slide rods 1304 are symmetrically distributed on the opposite sides of the double-headed threaded rod two 1302. Movable plates four 1305 are threadedly connected to the opposite sides of the double-headed threaded rod two 1302. Hinge brackets 1306 are fixedly connected to the outside of the movable plates four 1305. A third connecting rod 1307 is rotatably connected to the middle of the hinge bracket 1306. The third connecting rod 1307 is fixedly connected to the corresponding movable plate one 7. The grinding mechanism 16 includes a connecting frame 1601 slidably connected inside the second guide rail 15. An electric push rod 1602 is fixedly installed at one end of the connecting frame 1601 away from the second guide rail 15. The extended end of the electric push rod 1602 is fixedly connected to an abrasive plate 1603.

[0051] As can be seen from the above, when the workpiece 3 to be processed is cut into two groups by the cutting mechanism 12, the fourth stepper motor 1303 is turned on. The fourth stepper motor 1303 drives the double-headed threaded rod two 1302 to rotate, drives the two movable plates four 1305 on both sides to approach each other through the two groups of second slide rods 1304, separates the first threaded clamping rod 901 and the second threaded clamping rod 902. Furthermore, the linkage of the third connecting rod 1307 and the hinge 8 drives the two cut workpieces 3 to move away from each other through the inner support mechanism 10, and makes the cutting surfaces of the two workpieces 3 face forward. Then, through the second guide rail 15, the connecting frame 1601 drives the electric push rod 1602 to move towards the rear workpiece 3 to be processed until the abrasive plate 1603 abuts against the cutting surface of the workpiece 3. Then, the electric push rod 1602 is turned on, and the telescopic end of the electric push rod 1602 reciprocates telescopically, which can drive the abrasive plate 1603 to grind the workpiece 3.

[0052] Working principle: First, place the workpiece 3 to be processed on the top of the conveyor device 2. Move the workpiece 3 to be processed to the left through the conveyor device 2 until the infrared sensor 4 senses that the workpiece 3 to be processed reaches the specified location. Then the conveyor device 2 stops transporting the workpiece 3 to be processed. Next, turn on the cylinder 5. The cylinder 5 drives the workpiece 3 to separate from the conveyor device 2 through the arc-shaped support plate 6. Turn on the first stepping motor 907. The first stepping motor 907 drives the first threaded clamping rod 901 to rotate, and then drives the engaged second threaded clamping rod 902 to rotate synchronously. The first threaded clamping rod 901 and the second threaded clamping rod 902 drive the movable block 905 to slide along the first chute 903 through the first slider 904 until the connecting rod 906 abuts against both ends of the workpiece 3. Then turn on the second stepping motor 1009. The second stepping motor 1009 drives the lead screw 1003 to rotate. The lead screw 1003 drives the movable cylinder 1004 to move, and then through the first connecting rod 1005 and the second connecting rod 1006, the second movable plate 1007 moves away from the lead screw 1003 until the entire silica gel layer 1008 abuts against the inner wall of the workpiece 3;

[0053] After lowering the two arc-shaped semi-circular plates 1207 to both sides of the workpiece 3 through the first guide rail 11, turn on the third stepping motor 1204. The third stepping motor 1204 drives the first double-headed threaded rod 1203 to rotate, and then through the guidance of the two first slide rods 1205, the two third movable plates 1206 move closer to each other until the two arc-shaped semi-circular plates 1207 move closer to each other, surround the outside of the workpiece 3 and close. And the overall diameter formed by the two arc-shaped semi-circular plates 1207 is larger than that of the workpiece 3. Then turn on the drive motor 1211. The drive motor 1211 drives the arc-shaped toothed plate 1209 to rotate, and then the arc-shaped toothed plate 1209 on this side can enter the second chute 1208 of the other arc-shaped semi-circular plate 1207, so that the laser head 1214 rotates around the outer circumference of the workpiece 3. Thus, by turning on the laser head 1214, the middle part of the workpiece 3 can be cut around. After the cutting is completed, reset each arc-shaped toothed plate 1209, and reverse the third stepping motor 1204 and use the first guide rail 11 to move the two arc-shaped semi-circular plates 1207 away from the workpiece 3;

[0054] After the workpiece 3 to be processed is cut into two groups by the cutting mechanism 12, the fourth stepping motor 1303 is started.
