Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, in particular to a high-precision laser cutting device for quickly locating a cutting position of a steel plate. Background Art

[0002] Laser cutting is a thermal cutting method that uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves across the material, the holes continuously form a very narrow (such as about 0.1mm) cut. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby cutting the workpiece and completing the cutting of the material.

[0003] Laser cutting equipment can cut more shapes. During the cutting process, it is often necessary to cut special-shaped plates, which need to be fixed before cutting. Compared with conventional square plates, special-shaped plates are more difficult to fix. Therefore, in order to ensure the fixing effect, the fixing of some special-shaped plates is completed by the staff. The fixing efficiency is low, which will affect the working efficiency of the cutting device during continuous operation. Summary of the invention

[0016] Beneficial effects of the present invention:

[0017] 1. The high-precision laser cutting device described in the present invention is used for quickly positioning the cutting position of a steel plate. By setting a first arc rod and a second arc rod, the first slider and the second slider on the support beam move towards each other and move to a predetermined position. The motors on the first slider and the second slider work to drive the rotating shaft to rotate. The rotating shaft drives the first arc rod or the second arc rod to rotate. The outer arc surfaces of the first arc rod and the second arc rod contact the steel plate, thereby clamping and limiting the steel plate, so that the steel plate is located in the center of the first slider and the second slider, thereby quickly positioning the steel plate to facilitate cutting by the laser head.

[0018] 2. The high-precision laser cutting device described in the present invention is used to quickly locate the cutting position of a steel plate. By using multiple first arc rods and second arc rods, when positioning special-shaped steel plates, the edges of the special-shaped steel plates are uneven, and the corresponding first arc rods or second arc rods rotate at different angles, so that the first arc rods and the second arc rods can both be in close contact with the edge of the steel plate, so that steel plates of different shapes can be quickly fixed.

[0019] 3. The high-precision laser cutting device for quickly locating the cutting position of a steel plate described in the present invention, by setting a card slot and a contact switch, after the first arc rod and the second arc rod contact the steel plate, the contact switch in the corresponding card slot is triggered, and the first slider and the second slider are in a predetermined position. The position where the edge of the steel plate contacts the first arc rod or the second arc rod can be judged by distinguishing the contact switches in different positions, thereby judging whether the position of the steel plate is correct. When the edge of the steel plate is warped or other problems cause the position of the edge of the steel plate to be incorrect, it can be quickly judged by triggering the contact switch.

[0020] 4. The high-precision laser cutting device described in the present invention is used for quickly positioning the cutting position of a steel plate. By setting a first arc rod, a second arc rod and a negative pressure tube, after the edge of the steel plate is fixed by part of the first arc rod and the second arc rod, the first arc rod and the second arc rod located under the steel plate are lifted upward by the drive of the motor, so that the negative pressure tube at the top of the first arc rod and the second arc rod contacts the bottom of the steel plate, and then the negative pressure tube is evacuated by an external air pump. A rubber ring is provided at the end of the negative pressure tube. Under the action of the negative pressure tube, the rubber ring will be adsorbed on the bottom of the steel plate after contacting the steel plate, thereby fixing the steel plate. At this time, the first arc rod and the second arc rod located on both sides of the steel plate fix the steel plate to prevent the negative pressure tube from lifting the steel plate upward when contacting the bottom of the steel plate, causing the position of the steel plate to move. Then, the first arc rod and the second arc rod located on both sides of the steel plate rotate upward driven by the motor, thereby facilitating the laser head to cut the steel plate.

[0034] As a technical optimization scheme of the present invention, longitudinal slide bars 5 are provided on both sides of the cutting bed 1.

[0035] As a technical optimization solution of the present invention, a slide plate 15 is provided on the top of the first slider 12 and the second slider 13, the first arc rod 17 and the second arc rod 18 are both installed on the corresponding slide plate 15, and a slot 29 is provided on the side of the first arc rod 17 and the second arc rod 18 close to the steel plate 34. A mounting plate 14 is provided on the first slider 12 and the second slider 13, and the top of the mounting plate 14 is connected to the corresponding slide plate 15 by a fixing bolt 16. The mounting plate 14 is provided with a plurality of threaded holes that cooperate with the fixing bolt 16, and the spacing of the threaded holes is the same as the spacing of the adjacent cone plates 3. The crossbeam 7 can move along the length direction of the cutting bed 1 under the drive of the longitudinal slider 6, and the vertical slider 9 can move along the width direction of the cutting bed 1 under the drive of the transverse slider 8. The vertical slider 9 can move up and down in the vertical direction, so as to facilitate the laser head 10 to cut, and the slide plate 15 can move along the length direction of the mounting plate 14, so as to adjust the position of the first arc rod 17 and the second arc rod 18.

[0036] As a technical optimization solution of the present invention, the first arc rod 17 and the second arc rod 18 correspond to each other one by one, and the ends of the first arc rod 17 and the second arc rod 18 close to the slide 15 are fixedly connected to the rotating shaft 21, and the outer side of the rotating shaft 21 is provided with a shaft sleeve 22, and the outer side of the shaft sleeve 22 is fixedly connected to the top of the slide 15. A motor 23 is provided on one side of the rotating shaft 21, and the output end of the motor 23 is fixedly connected to the rotating shaft 21. When multiple first arc rods 17 and second arc rods 18 are used, when positioning the special-shaped steel plate 34, the edge of the special-shaped steel plate 34 is uneven, and the corresponding first arc rod 17 or second arc rod 18 rotates at different angles, so that the first arc rod 17 and the second arc rod 18 can both be in close contact with the edge of the steel plate 34, so that steel plates 34 of different shapes can be quickly fixed.

[0037] As a technical optimization solution of the present invention, a cleaning rod 19 is provided on the inner arc surface of the first arc rod 17 and the second arc rod 18, and the cleaning rod 19 is fixed to the first arc rod 17 or the second arc rod 18 by screws. Cleaning brushes are provided on both sides of the cleaning rod 19, and the cleaning brushes can contact the cone plate 3. A scraper 20 is provided on one side of the cleaning rod 19, and the scraper 20 can contact the cone plate 3. An abutment plate 30 is provided in the slot 29, and a contact switch 32 is fixedly installed on the side wall of the slot 29. A reset spring 31 is provided on the outside of the contact switch 32, and one end of the reset spring 31 is fixedly connected to the side wall of the slot 29, and the other end is fixedly connected to the abutment plate 30. After the first arc rod 17 and the second arc rod 18 come into contact with the steel plate 34, the contact switch 32 in the corresponding slot 29 is triggered. At this time, the first slider 12 and the second slider 13 are at the predetermined positions. The position where the edge of the steel plate 34 contacts the first arc rod 17 or the second arc rod 18 can be judged by distinguishing the contact switches 32 at different positions, thereby judging whether the position of the steel plate 34 is correct. When the edge of the steel plate 34 is warped or other problems cause the position of the edge of the steel plate 34 to be incorrect, it can be quickly judged by triggering the contact switch 32.

[0038] As a technical optimization solution of the present invention, a plurality of air holes are provided on the first arc rod 17 and the second arc rod 18, and the air holes are connected to the dust suction pipe 28. A plurality of dust suction holes 33 are provided on the first arc rod 17 and the second arc rod 18. During the cutting process, the powder generated by the cutting can be sucked away through the external air pump, the dust suction pipe 28 and the dust suction holes 33, thereby reducing the accumulation of powder on the equipment, reducing the probability of equipment failure, and reducing the frequency of maintenance.

[0039] As a technical optimization solution of the present invention, negative pressure tubes 27 are provided inside the first arc rod 17 and the second arc rod 18 , and a rubber ring is provided on the top of the negative pressure tube 27 .

[0040] As a technical optimization solution of the present invention, a fixing block 24 is provided at the top of the first arc rod 17 and the second arc rod 18, and a connecting shaft 26 is fixedly connected at both ends of the fixing block 24. The connecting shaft 26 is rotatably connected to the first arc rod 17 or the second arc rod 18 through a fixing plate 25, and a negative pressure tube 27 passes through the fixing block 24 and is fixedly connected to the fixing block 24. A fixing block 24 is provided at the top of the first arc rod 17 and the second arc rod 18, and the fixing block 24 can rotate along the connecting shaft 26, so that the negative pressure tube 27 at the top of the first arc rod 17 and the second arc rod 18 can be completely adsorbed on the bottom of the steel plate 34 at any position within a certain range, avoiding a gap between the end of the negative pressure tube 27 and the steel plate 34, resulting in a poor fixing effect.

[0041] Working principle: Both the negative pressure pipe 27 and the dust suction pipe 28 are externally connected to an air pump. When in use, first place the steel plate 34 on the cutting bed 1. A baffle (not shown in the figure) is connected to the top of the cutting bed 1 by screws. The baffle can contact the steel plate 34 and limit the steel plate 34 in the width direction of the cutting bed 1. Then the first slider 12 and the second slider 13 on the support beam 11 move towards each other and move to a predetermined position. The motor 23 on the first slider 12 and the second slider 13 works to drive the rotating shaft 21 to rotate. The rotating shaft 21 drives the first arc rod 17 or the second arc rod 18 to rotate. The outer arc surface of the first arc rod 17 and the second arc rod 18 contacts the steel plate 34, thereby clamping and limiting the steel plate 34, so that the steel plate 34 is located in the center of the first slider 12 and the second slider 13, thereby quickly positioning the steel plate 34 to facilitate cutting by the laser head 10.

[0042] Since multiple first arc rods 17 and second arc rods 18 are used, when positioning the special-shaped steel plate 34, the edge of the special-shaped steel plate 34 is uneven, and the corresponding first arc rods 17 or second arc rods 18 rotate at different angles, so that the first arc rods 17 and the second arc rods 18 can both be in close contact with the edge of the steel plate 34, so that steel plates 34 of different shapes can be quickly fixed.

[0043] When the first arc rod 17 and the second arc rod 18 come into contact with the steel plate 34, the contact switch 32 in the corresponding slot 29 is triggered. At this time, the first slider 12 and the second slider 13 are at the predetermined positions. The position where the edge of the steel plate 34 contacts the first arc rod 17 or the second arc rod 18 can be judged by distinguishing the contact switches 32 at different positions, thereby judging whether the position of the steel plate 34 is correct. When the edge of the steel plate 34 is warped or other problems cause the position of the edge of the steel plate 34 to be incorrect, it can be quickly judged by triggering the contact switch 32.

[0044] The first arc rod 17 and the second arc rod 18 have exactly the same structure and principle. The first arc rod 17 is described below as an example. The outer arc surface of the first arc rod 17 is provided with a slot 29, and an abutment plate 30 is provided inside the slot 29. When the first arc rod 17 contacts the steel plate 34, the abutment plate 30 first contacts the steel plate 34, and the steel plate 34 pushes the abutment plate 30 to move, thereby squeezing the return spring 31. After the return spring 31 is compressed, the abutment plate 30 contacts the contact switch 32; when the return spring 31 is squeezed, the steel plate 34 contacts the inner wall of the slot 29, thereby clamping the edge of the steel plate 34, so that the first arc rod 17 has a better fixing effect on the steel plate 34, and the return spring 31 can buffer the steel plate 34 to prevent the first arc rod 17 from rotating along the rotating shaft 21. The force of contacting the edge of the steel plate 34 is large, causing damage to the first arc rod 17.

[0045] When it is necessary to cut the edge of the steel plate 34, the steel plate 34 is fixed by using part of the first arc rod 17 and part of the second arc rod 18. After the edge of the steel plate 34 is fixed by part of the first arc rod 17 and part of the second arc rod 18, the remaining first arc rod 17 and second arc rod 18 are located below the steel plate 34. When the edge of the steel plate 34 is fixed by part of the first arc rod 17 and second arc rod 18, the first arc rod 17 and second arc rod 18 located below the steel plate 34 are lifted upward under the drive of the motor 23, so that the negative pressure tube 27 at the top of the first arc rod 17 and second arc rod 18 is in contact with the bottom of the steel plate 34, and then the negative pressure tube 27 is evacuated by an external air pump. The end of the negative pressure tube 27 is provided with a rubber The rubber ring, under the action of the negative pressure tube 27, will be adsorbed on the bottom of the steel plate 34 after contacting the steel plate 34, thereby fixing the steel plate 34, and the first arc rod 17 and the second arc rod 18 located below the steel plate 34 move downward a short distance to tighten the negative pressure tube 27. At this time, the first arc rod 17 and the second arc rod 18 located on both sides of the steel plate 34 fix the steel plate 34 to prevent the negative pressure tube 27 from lifting the steel plate 34 upward when contacting the bottom of the steel plate 34, causing the position of the steel plate 34 to move, and then the first arc rod 17 and the second arc rod 18 located on both sides of the steel plate 34 rotate upward driven by the motor 23, thereby facilitating the laser head 10 to cut the steel plate 34.

[0046] A fixing block 24 is provided at the top of the first arc rod 17 and the second arc rod 18, and the fixing block 24 can rotate along the connecting shaft 26, so that the negative pressure tube 27 at the top of the first arc rod 17 and the second arc rod 18 can be completely adsorbed on the bottom of the steel plate 34 at any position within a certain range, avoiding a gap between the end of the negative pressure tube 27 and the steel plate 34, resulting in a poor fixing effect.

[0047] A plurality of dust suction holes 33 are provided on the first arc rod 17 and the second arc rod 18. During the cutting process, the powder generated by the cutting can be sucked away through the external air pump, the dust suction pipe 28 and the dust suction holes 33, thereby reducing the accumulation of powder on the equipment, reducing the probability of equipment failure and reducing the frequency of maintenance.

[0048] When the first arc rod 17 and the second arc rod 18 move, the cleaning rod 19 can clean the cone plate 3 to prevent debris on the cone plate 3, which will cause the steel plate 34 to be uneven, resulting in a poor fixing effect of the first arc rod 17 and the second arc rod 18, affecting the cutting effect; the laser head 10 will also cause certain damage to the cone plate 3 under the steel plate 34 during cutting. After the first arc rod 17 and the second arc rod 18 rotate upward by a certain angle, the scraper 20 can contact the cone plate 3 and move along the support beam 11 driven by the first slider 12 and the second slider 13, so as to scrape off the burrs on the cone plate 3; when cleaning the cone plate 3, the dust suction pipe 28 simultaneously exhausts air to increase the cleaning effect.

[0049] The scraper 20 and the cleaning rod 19 can provide certain protection for the inner curved surface of the first curved rod 17 or the second curved rod 18 to prevent the laser head 10 from causing damage to the first curved rod 17 or the second curved rod 18 during cutting. The scraper 20 and the cleaning rod 19 are connected to the first curved rod 17 or the second curved rod 18 by screws for easy disassembly and replacement.

[0050] The crossbeam 7 can move along the length direction of the cutting bed 1 driven by the longitudinal slider 6, and the vertical slider 9 can move along the width direction of the cutting bed 1 driven by the transverse slider 8. The vertical slider 9 can move up and down in the vertical direction, thereby facilitating cutting by the laser head 10.

[0051] The slide plate 15 can move along the length direction of the mounting plate 14 to adjust the positions of the first arc-shaped rod 17 and the second arc-shaped rod 18 .

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
