Description

Technical Field

[0001] The present application relates to the technical field of laser cutting, and in particular to a clamp device for laser cutting. Background Art

[0002] Laser cutting is a technology that uses a high-power density laser beam to irradiate the material, rapidly heating it to the melting point or boiling point, melting or vaporizing the material to form holes, and using high-speed airflow to blow away the melted or vaporized material. As the beam moves, the holes continuously form slits to complete the cutting. Laser cutting has the characteristics of high precision, fast cutting speed, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs.

[0003] At present, in the precision processing of sheet parts, in order to reduce the impact of laser thermal effect on sheet parts, as well as the problem of slag accumulation caused by laser cutting affecting cutting quality, high-speed airflow is usually used to blow away the slag produced by the cutting of sheet parts. At the same time, the high-speed airflow will quickly take away the heat on the sheet parts, thereby improving the cutting quality of the sheet parts.

[0004] However, during the laser cutting process of sheet parts, the high-speed airflow will cause the sheet parts to shake during the cutting process, resulting in the cutting quality of the sheet parts being affected. When a universal clamp is used to fix the sheet parts on all sides, the cutting part of the sheet parts will still shake under the impact of the high-speed airflow, which will still affect the cutting quality of the sheet parts, thus having some shortcomings. Summary of the invention

[0005] In order to improve the cutting problem caused by high-speed airflow during the laser cutting process of sheet parts, the present application provides a clamping device for laser cutting.

[0007] By adopting the above technical solution, the feeding mechanism first transfers the sheet to the top column on the cutting pool, and then the clamping assembly completely presses the surface of the sheet on several top columns. Thereafter, the sliding assembly drives the laser cutting head to cut the sheet. During the continuous movement of the laser cutting head, the clamping assembly moves with the laser cutting head and presses the surface of the sheet against the top column, thereby reducing the shaking effect caused by the high-speed airflow impacting the sheet, thereby improving the cutting quality of the sheet.

[0009] By adopting the above technical solution, the control system first starts the vertical cylinder to make the laser cutting head close to the upper surface of the sheet, and then starts the horizontal cylinder and the longitudinal cylinder through the control system according to the shape to be cut to drive the laser cutting head to move freely on the upper surface of the sheet, thereby achieving the cutting effect on the sheet. At the same time, the distance between the laser cutting head and the sheet can be continuously adjusted according to the thickness of the sheet.

[0010] Optionally, the clamping assembly includes a clamping frame rotatably disposed on the base, a cutting cone tube being arranged on the clamping frame, the cutting cone tube being used to be sleeved on the laser cutting head, a rotating part for driving the clamping frame to rotate is provided on the base, a bag ring is coaxially sleeved on the cutting cone tube, the interior of the bag ring is hollow and made of elastic heat-resistant material, a stamping part for stamping the interior of the bag ring is provided on the base, and a plurality of elastic pull ropes are provided between the circumferential outer wall of the bag ring and the clamping frame.

[0011] By adopting the above technical scheme, the control system first starts the vertical cylinder to insert the laser cutting head on the cutting cone tube, and then the stamping part punches into the bladder ring, the internal pressure of the bladder ring increases and expands, so that the sheet is pressed against the top column, and then the transverse cylinder and the longitudinal cylinder drive the laser cutting head to move freely, and the laser cutting head drives the cutting cone tube to move synchronously, the bladder ring and the elastic pull rope are deformed, and the recovery deformation force of the elastic pull rope makes the bladder ring restore its shape, the sheet on the inside of the cutting cone tube is continuously cut by the laser cutting head, and the sheet on the outside of the cutting cone tube is always pressed against the top column by the deformed bladder ring, so as to reduce the shaking degree of the sheet blown by the high-speed airflow, and at the same time, the cutting cone tube will restrain the sparks generated by the cutting of the laser cutting head, and under the restraining force of the cutting cone tube, the high-speed airflow makes the sparks and other cutting waste generated inside the cutting cone tube be quickly discharged from the cutting seam of the sheet, so that the cutting seam of the sheet is quickly cooled down, which is beneficial to improve the cutting quality of the sheet.

[0012] Optionally, the rotating member includes a fixed seat arranged on the base, and a rotating motor for driving the pressing frame to rotate is arranged on the fixed seat, and the rotating motor is electrically connected to a control system.

[0013] By adopting the above technical solution, after the sheet is placed on the top column, the control system starts the rotating motor, and the rotating motor controls the pressing frame to rotate so that the pressing frame rotates to the top of the sheet, so that the inflated bag ring can press the sheet on the top column.

[0014] Optionally, the stamping part includes a high-pressure fan disposed on the fixing seat and electrically connected to a control system, and a hose is connected between an air outlet end of the high-pressure fan and the bag ring.

[0015] By adopting the above technical solution, when the pressing frame rotates to the top of the sheet, the control system starts the high-pressure fan, and the high-pressure fan fills high-pressure gas into the bag ring through the hose, thereby causing the bag ring to expand, and then the surface of the sheet is pressed against the top column, while reducing the impact of the movement of the bag ring on the sheet.

[0017] By adopting the above technical solution, the connecting ring fixes the cutting cone tube on the laser cutting head. When the cutting cone tube moves synchronously with the laser cutting head, the ball bearing reduces the friction between the cutting cone tube and the sheet, reducing the possibility of surface damage to the sheet. At the same time, the scraper ring knife on the cutting cone tube scrapes off the waste residue on the surface of the sheet, thereby reducing the impact of the waste residue on the bag ring and improving the cutting quality of the sheet.

[0018] Optionally, the feeding mechanism includes a manipulator disposed on the base and electrically connected to the control system, the manipulator is provided with a suction plate, the suction plate is provided with a plurality of suction cups, and a limit frame is detachably provided on the cutting pool, the limit frame is used to position the sheet.

[0019] By adopting the above technical solution, the robot places the sheet on the limiting frame through the suction cup.

[0020] Optionally, several of the top columns are slidably arranged on the cutting pool, and several sliding grooves are opened on the cutting pool. The top columns correspond to the sliding grooves one by one, and a compression spring is provided between the end of the top column facing away from the sheet and the sliding groove.

[0021] By adopting the above technical solution, when the bag ring expands and deforms, the sheet is pressed against the top column, the top column squeezes the compression spring, and the compression spring is deformed, so that the sheet is in a flexible compression effect, thereby reducing the possibility of the sheet being squeezed and causing surface deformation, and further improving the cutting quality of the sheet.

[0022] Optionally, a side of the limiting frame facing away from the compression spring is flush with an end surface of the top column where no sheet material is placed.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. The feeding mechanism first transfers the sheet to the top column on the cutting pool, and then the pressing component completely presses the surface of the sheet on several top columns. After that, the sliding component drives the laser cutting head to cut the sheet. During the continuous movement of the laser cutting head, the pressing component moves with the laser cutting head and presses the surface of the sheet on the top column, thereby reducing the shaking effect caused by the high-speed airflow impacting the sheet, thereby improving the cutting quality of the sheet; 2. The control system first starts the vertical cylinder to insert the laser cutting head into the cutting cone tube, and then the stamping part punches into the bag ring. The internal pressure of the bag ring increases and expands, so that the sheet is pressed against the top column. Then the horizontal cylinder and the longitudinal cylinder drive the laser cutting head to move freely, and the laser cutting head drives the cutting cone tube to move synchronously. The bag ring and the elastic drawstring are deformed, and the recovery deformation force of the elastic drawstring makes the bag ring restore its shape. The sheet inside the cutting cone tube is continuously cut by the laser cutting head, while the sheet outside the cutting cone tube is always pressed against the top column by the deformed bag ring, so as to reduce the shaking degree of the sheet blown by the high-speed airflow. At the same time, the cutting cone tube will constrain the sparks generated by the cutting of the laser cutting head. Under the restraining force of the cutting cone tube, the high-speed airflow makes the sparks and other cutting waste generated inside the cutting cone tube be quickly discharged from the cutting seam of the sheet, so that the cutting seam of the sheet is quickly cooled down, which is beneficial to improve the cutting quality of the sheet. 3. The connecting ring fixes the cutting cone on the laser cutting head. When the cutting cone moves synchronously with the laser cutting head, the ball bearing reduces the friction between the cutting cone and the sheet, reducing the possibility of surface damage to the sheet. At the same time, the scraping ring knife on the cutting cone scrapes off the waste residue on the surface of the sheet, thereby reducing the impact of the waste residue on the bag ring and improving the cutting quality of the sheet.

A compression spring 13 is supported between the end of the top column 6 facing away from the sheet 0 and the sliding groove 12.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The feeding mechanism 3 is used to place the sheet 0 on a plurality of top pillars 6. The feeding mechanism 3 includes a manipulator 31 arranged on the base 1 and electrically connected to the control system. A suction plate 32 is bolted to the manipulator 31.

The limiting frame 34 is used to position the sheet 0. The surface of the limiting frame 34 facing away from the compression spring 13 is flush with the end surface of the top pillar 6 where the sheet 0 is not placed.

[0034] The worker first installs the limit frame 34 on the cutting pool 2 according to the size of the sheet 0, and makes the upper surface of the limit frame 34 flush with the upper end surface of the top column 6, and then starts the robot 31 through the control system. The robot 31 transfers the sheet 0 to the limit frame 34 through several suction cups 33 on the suction plate 32.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A laser cutting head 4 is slidably arranged on the base 1, and a sliding assembly 5 for driving the laser cutting head 4 to slide is arranged on the base 1. The sliding assembly 5 includes a transverse slot plate 51 welded on the base 1, and a longitudinal slot plate 52 is slidable along the length direction of the transverse slot plate 51. A transverse cylinder 53 electrically connected to the control system is bolted to the transverse slot plate 51, and the longitudinal slot plate 52 is welded to the piston rod of the transverse cylinder 53.

[0036] Reference Figure 1 , Figure 2 and Figure 3A vertical plate 54 is slidably disposed on the longitudinal groove plate 52 along its length direction, a longitudinal cylinder 55 electrically connected to the control system is bolted to the longitudinal groove plate 52, the vertical plate 54 is welded to the piston rod of the longitudinal cylinder 55, a vertical cylinder 56 electrically connected to the control system is bolted to the vertical plate 54, the laser cutting head 4 is bolted to the piston rod of the vertical cylinder 56, and the extension directions of the piston rods of the transverse cylinder 53, the longitudinal cylinder 55 and the vertical cylinder 56 are perpendicular to each other.

[0037] The worker starts the vertical cylinder 56 through the control system, so that the piston rod of the vertical cylinder 56 pushes the laser cutting head 4 close to the upper surface of the sheet 0, and then starts the transverse cylinder 53 and the longitudinal cylinder 55 through the control system according to the shape of the sheet 0 to be cut. Through the mutual cooperation of the transverse cylinder 53 and the longitudinal cylinder 55, the laser cutting head 4 can move freely on the upper surface of the sheet 0 for cutting.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A clamping assembly 7 is arranged on the base 1. The clamping assembly 7 moves with the laser cutting head 4 and always presses the surface of the sheet 0 against the top column 6. The clamping assembly 7 includes a clamping frame 71 rotatably arranged on the base 1. A cutting cone tube 72 is arranged on the clamping frame 71. The cutting cone tube 72 is used to be sleeved on the laser cutting head 4. A connecting ring 8 is sleeved on the laser cutting head 4. A connecting groove 9 for the connecting ring 8 to be plugged into is opened on the cutting cone tube 72.

[0039] Reference Figure 2 , Figure 3 and Figure 4 A plurality of balls 10 are arranged to roll on the cutting cone 72, and the plurality of balls 10 are evenly distributed on the cutting cone 72 in the circumferential direction. The plurality of balls 10 are used to abut against the surface of the sheet 0. A scraper ring knife 11 is coaxially welded on the inner side of the cutting cone 72, and the scraper ring knife 11 is closely attached to the surface of the sheet 0. A rotating member 73 for driving the pressing frame 71 to rotate is arranged on the base 1.

[0040] Reference Figure 1 and Figure 2 The rotating member 73 includes a fixed seat 731 arranged on the base 1, and a rotating motor 732 for driving the pressing frame 71 to rotate is bolted to the fixed seat 731. The rotating motor 732 can adopt a reciprocating motor in the prior art. A gear set (not shown in the figure) for transmitting the torque between the rotating motor 732 and the pressing frame 71 is arranged inside the fixed seat 731. The rotating motor 732 is electrically connected to the control system.

[0041] Reference Figure 2 , Figure 3 and Figure 4A bag ring 74 is coaxially sleeved on the cutting cone 72. The interior of the bag ring 74 is hollow and made of elastic heat-resistant material. A tensile rubber ring 14 is bonded to the circumferential outer wall of the bag ring 74. A number of elastic pull ropes 76 are evenly bonded circumferentially between the circumferential outer wall of the tensile rubber ring 14 and the clamping frame 71.

[0042] Reference Figure 1 , Figure 2 and Figure 3 A stamping part 75 for stamping the inside of the bag ring 74 is arranged on the base 1. The stamping part 75 includes a high-pressure fan 751 bolted to the fixing seat 731 and electrically connected to the control system. A hose 752 is connected between the air outlet end of the high-pressure fan 751 and the bag ring 74, and the hose 752 passes through the clamping frame 71.

[0043] After the sheet 0 is placed in the limit frame 34, the worker starts the rotating motor 732 through the control system. The output shaft of the rotating motor 732 drives the clamping frame 71 to rotate to the top of the sheet 0 through the gear set. At this time, the control system stops supplying power to the rotating motor 732, and then the control system starts the horizontal cylinder 53, the longitudinal cylinder 55 and the vertical cylinder 56, so that the piston rod of the vertical cylinder 56 drives the laser cutting head 4 to insert into the cutting cone tube 72 until the connecting ring 8 on the laser cutting head 4 is inserted into the connecting groove 9 on the cutting cone tube 72.

[0044] Then the control system starts the high-pressure fan 751, and the high-pressure fan 751 fills high-pressure gas into the bag ring 74 through the hose 752. The bag ring 74 expands and deforms. The expanded bag ring 74 presses the sheet 0 against the top column 6. The top column 6 descends to squeeze the compression spring 13. The reaction force of the compression spring 13 makes the sheet 0 close to the lower surface of the bag ring 74.

[0045] Driven by the transverse cylinder 53 and the longitudinal cylinder 55, the laser cutting head 4 drives the cutting cone 72 to move synchronously, and the ball 10 on the cutting cone 72 rolls with the upper surface of the sheet 0. The waste slag formed by the sparks generated by the laser cutting head 4 when cutting the sheet 0 will be constrained in the cutting cone 72. Under the constraining effect of the cutting cone 72, the high-speed airflow carries the sparks and waste slag and is discharged from the cutting seam of the sheet 0.

[0046] At the same time, the scraper ring 11 on the cutting cone 72 scrapes off the residual waste residue on the upper surface of the sheet 0 during the movement of the cutting cone 72, and discharges it from the cutting seam of the sheet 0 along with the high-speed airflow. In the process of discharging the waste residue formed by the sparks in the cutting cone 72, the high-speed airflow quickly takes out the heat at the cutting seam of the sheet 0, thereby rapidly reducing the temperature of the sheet 0.

[0047] As the cutting cone 72 moves synchronously with the laser cutting head 4, the bag ring 74 and the elastic pull rope 76 are constantly deformed, and the restoring deformation force of the elastic pull rope 76 forces the bag ring 74 to restore its shape, so that the sheet 0 is always pressed against the top column 6 during the cutting process.

[0048] The implementation principle of a clamp device for laser cutting in an embodiment of the present application is as follows: a worker first installs a limit frame 34 on the cutting pool 2 according to the size of the sheet 0, and at the same time makes the upper surface of the limit frame 34 flush with the upper end surface of the top column 6, and then starts the manipulator 31 through the control system, and the manipulator 31 transfers the sheet 0 to the limit frame 34 through a number of suction cups 33 on the suction plate 32.

[0049] The worker starts the vertical cylinder 56 through the control system, so that the piston rod of the vertical cylinder 56 pushes the laser cutting head 4 close to the upper surface of the sheet 0, and then starts the transverse cylinder 53 and the longitudinal cylinder 55 through the control system according to the shape of the sheet 0 to be cut. Through the mutual cooperation of the transverse cylinder 53 and the longitudinal cylinder 55, the laser cutting head 4 can move freely on the upper surface of the sheet 0 for cutting.

[0050] After the sheet 0 is placed in the limit frame 34, the worker starts the rotating motor 732 through the control system. The output shaft of the rotating motor 732 drives the clamping frame 71 to rotate to the top of the sheet 0 through the gear set. At this time, the control system stops supplying power to the rotating motor 732, and then the control system starts the horizontal cylinder 53, the longitudinal cylinder 55 and the vertical cylinder 56, so that the piston rod of the vertical cylinder 56 drives the laser cutting head 4 to insert into the cutting cone tube 72 until the connecting ring 8 on the laser cutting head 4 is inserted into the connecting groove 9 on the cutting cone tube 72.

[0051] Then the control system starts the high-pressure fan 751, and the high-pressure fan 751 fills high-pressure gas into the bag ring 74 through the hose 752. The bag ring 74 expands and deforms. The expanded bag ring 74 presses the sheet 0 against the top column 6. The top column 6 descends to squeeze the compression spring 13. The reaction force of the compression spring 13 makes the sheet 0 close to the lower surface of the bag ring 74.

[0052] Driven by the transverse cylinder 53 and the longitudinal cylinder 55, the laser cutting head 4 drives the cutting cone 72 to move synchronously, and the ball 10 on the cutting cone 72 rolls with the upper surface of the sheet 0. The waste slag formed by the sparks generated by the laser cutting head 4 when cutting the sheet 0 will be constrained in the cutting cone 72. Under the constraining effect of the cutting cone 72, the high-speed airflow carries the sparks and waste slag and is discharged from the cutting seam of the sheet 0.

[0053] At the same time, the scraper ring 11 on the cutting cone 72 scrapes off the residual waste residue on the upper surface of the sheet 0 during the movement of the cutting cone 72, and discharges it from the cutting seam of the sheet 0 along with the high-speed airflow. In the process of discharging the waste residue formed by the sparks in the cutting cone 72, the high-speed airflow quickly takes out the heat at the cutting seam of the sheet 0, thereby rapidly reducing the temperature of the sheet 0.

[0054] As the cutting cone 72 moves synchronously with the laser cutting head 4, the bag ring 74 and the elastic pull rope 76 are constantly deformed, and the restoring deformation force of the elastic pull rope 76 forces the bag ring 74 to restore its shape, so that the sheet 0 is always pressed against the top column 6 during the cutting process.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
