Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology, and specifically relates to a flexible laser cutting bracket for automotive parts. Background Technology

[0002] Laser cutting utilizes a focused, high-power-density laser beam to irradiate a workpiece, causing the irradiated product to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the laser beam blows away the molten material, thereby cutting the workpiece. Laser cutting is a type of thermal cutting method.

[0003] Currently, Chinese utility model patent CN219581977U discloses a stabilizing bracket for a laser cutting machine, including a support arm and a connecting device. A limiting metal plate is threadedly connected to the front of the support arm, and a main body mechanism is threadedly connected to the top surface of the support arm. A support mechanism is threadedly connected to the rear end of the main body mechanism. The support arm is slidably connected to the left and right end surfaces of the connecting device. The support mechanism includes a support unit and a limiting unit, arranged sequentially from bottom to top. This stabilizing bracket for a laser cutting machine, by setting a metal support rod, a metal support plate, and a limiting metal plate, can limit and fix the position of the support arm, preventing it from falling and increasing its service life. It also facilitates adjustment of the connecting device's position and limits the position of the metal sliding plate, making it easy to disassemble and replace the support arm, further extending the device's service life.

[0004] During use, the laser support does not allow for manual placement of the material to be cut onto the support, causing the material to wobble during laser cutting and resulting in inaccurate cutting position. Furthermore, when the laser head needs to be replaced or repaired, it requires professional personnel, increasing the maintenance cost and downtime of the laser cutting machine. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible laser cutting bracket for automotive parts. Its advantages are that it can fix the material to be cut and facilitate the disassembly and maintenance of the laser head.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flexible laser cutting bracket for automotive parts, comprising a bracket body, positioning shells welded to both sides of the bracket body, a motor welded to the rear side of the positioning shells, a bidirectional threaded rod welded to the output end of the motor, threaded sleeves threaded to the front and rear sides of the surface of the bidirectional threaded rod, a movable plate welded to the top of the threaded sleeves, a connecting plate provided at the top of the inner cavity of the bracket body, a laser head provided at the bottom of the connecting plate, and a locking plate welded to the rear side of the bottom of the connecting plate. The inner cavity is engaged with the laser head. A positioning plate is provided on the front side of the first positioning plate. Fixed plates are movably connected to both sides of the first positioning plate by axle pins. A retaining shell is sleeved between opposite sides of the two fixed plates. A positioning rod is welded to opposite sides of the two fixed plates. A spring is welded to the rear side of the positioning rod. A movable rod is welded to the rear side of the spring. The inner cavity of the movable rod is sleeved with the positioning rod. A retaining plate is welded to the front side of the movable rod. The front sides of the two retaining plates are welded to the inner cavities of the retaining shell. A retaining frame is provided on the rear side of the retaining shell. The rear side of the retaining frame passes through the second positioning plate and engages with the first positioning plate.

[0007] The above technical solution involves the following steps: When fixing the material during cutting, the user places the material to be cut at the bottom of the inner cavity of the support body, in contact with the ventilation shell. The user then starts the motor, which drives the first bidirectional threaded rod to rotate. Simultaneously, the rotation of the first bidirectional threaded rod causes the threaded sleeve and positioning plate connected to it to move towards the center of the support body. Once the positioning plate has engaged the material to be cut, the user turns off the motor and rotates the knob to rotate the second bidirectional threaded rod. Simultaneously, the rotation of the second bidirectional threaded rod causes the second movable plate to fix both sides of the material. This setup allows for fixing the material during laser cutting. When the laser head needs to be disassembled for maintenance, the user pulls the retaining shell, causing the movable rod to compress the spring. When the retaining shell moves to the designated position, the user uses the retaining shell to drive the fixing plate to move in a ring through the shaft pin. When the fixing plate moves to the designated position, the user disengages the retaining frame from the first locking plate, and then disengages the second locking plate from the first locking plate. This setup allows for quick disassembly of the laser head when maintenance is required.

[0008] The present invention is further configured such that a knob is movably connected to each opposite side of the inner cavity of the positioning plate, and a bidirectional threaded rod is welded between the opposite sides of the knobs, and a movable plate is threadedly connected to each opposite side of the surface of the bidirectional threaded rod.

[0009] The above technical solution uses a knob, a two-way threaded rod, and a movable plate to fix both sides of the material. This allows the material to be clamped on both sides when the user cuts it, and further fixes the position of the material when it is cut by the laser head.

[0010] The present invention is further configured such that positioning frames are welded to both the front and rear sides of the bracket body, and the inner cavity of the positioning frame is movably connected to an anti-slip plate via a pivot pin.

[0011] The above technical solution is adopted: by setting a positioning frame and an anti-slip plate, the moving position of the support body is fixed, which can fix the position of the support body when the user cuts the material through the support body, and prevent the position of the support body from shifting during the cutting process.

[0012] The present invention is further configured such that anti-slip blocks are welded to opposite sides of the inner cavity of the positioning frame, and the surface of the anti-slip blocks engages with the anti-slip plate.

[0013] The above technical solution is adopted: by setting anti-slip blocks, the rotation angle of the anti-slip plate is fixed, and the position of the anti-slip plate can be fixed when the anti-slip plate is idle, preventing the position of the anti-slip plate from rotating through the connection between the shaft pin and the positioning frame when the bracket body moves.

[0014] The present invention is further configured such that ventilation shells are welded to both sides of the bottom of the support body, and three fans are welded to the bottom of the inner cavity of the ventilation shell. A ventilation shell is welded to the top of the ventilation shell, and a cooling copper pipe is provided in the inner cavity of the ventilation shell.

[0015] The above technical solution involves setting up a ventilation shell, a fan, a ventilation housing, and cooling copper pipes to cool the material. This ensures the overall temperature of the material during laser cutting and prevents deformation of the material during laser cutting.

[0016] The present invention is further configured such that a locking rod is welded to both sides of the top of the positioning plate, and the top of the locking rod is engaged with the inner cavity of the connecting plate.

[0017] The above technical solution is adopted: by setting a locking rod, the movement position of the positioning plate is limited, which can facilitate the alignment of the positioning plate with the locking plate after the laser head is repaired, and prevent the position of the positioning plate from shifting during installation.

[0018] The present invention is further configured such that two fixing rods are welded to the top and bottom of the rear side of the fixing shell, and a second locking rod is sleeved in the inner cavity of the fixing rod, and the rear side of the second locking rod is welded to the fixing plate.

[0019] The above technical solution is adopted: by setting a fixing rod and a second locking rod, the moving position of the fixed shell is fixed to prevent the fixed shell from separating from the fixed plate when the fixed shell drives the fixed plate to move in a circle.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. When fixing the material during cutting, the user places the material to be cut at the bottom of the inner cavity of the support body, in contact with the ventilation shell. Then, the user starts the motor, which drives the first bidirectional threaded rod to rotate. At the same time, the rotation of the first bidirectional threaded rod drives the threaded sleeve and positioning plate connected to it to move towards the center of the support body. After the positioning plate has completed the engagement of the material to be cut, the user turns off the motor and rotates the knob to drive the second bidirectional threaded rod to rotate. At the same time as the second bidirectional threaded rod rotates, it drives the second movable plate to fix the two sides of the material. This setting can fix the material to be cut when the laser cutting machine is cutting the material.

[0022] 2. When the laser head needs to be disassembled and repaired, the user pulls the retaining shell to drive the movable rod to compress the spring. After the retaining shell moves to the designated position, the user drives the fixing plate to move in a circle through the shaft pin. When the fixing plate moves to the designated position, the user disengages the retaining frame from the locking plate. Then the user disengages the positioning plate from the locking plate. This setting allows for quick disassembly of the laser head when the user needs to repair it. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] refer to Figures 1-6 The flexible laser cutting bracket for automotive parts includes a bracket body 1. Positioning shells 2 are welded to both sides of the bracket body 1. A motor 3 is welded to the rear side of the positioning shells 2. A bidirectional threaded rod 4 is welded to the output end of the motor 3. Threaded sleeves 5 are threaded to the front and rear sides of the surface of the bidirectional threaded rod 4. A movable plate 1 is welded to the top of the threaded sleeve 5. A connecting plate 7 is provided at the top of the inner cavity of the bracket body 1.

[0033] Furthermore, knobs 17 are movably connected to opposite sides of the inner cavity of the positioning plate 6, and a two-way threaded rod 18 is welded between the opposite sides of the knobs 17. Movable plates 19 are threadedly connected to opposite sides of the surface of the two-way threaded rod 18.

[0034] Furthermore, positioning frames 20 are welded to both the front and rear sides of the bracket body 1, and anti-slip plates 21 are movably connected to the inner cavity of the positioning frames 20 through a pivot pin.

[0035] Furthermore, anti-slip blocks 22 are welded to opposite sides of the inner cavity of the positioning frame 20, and the surface of the anti-slip block 22 is engaged with the anti-slip plate 21.

[0036] Furthermore, ventilation shells 23 are welded to both sides of the bottom of the support body 1, and three fans 24 are welded to the bottom of the inner cavity of the ventilation shell 23. A ventilation shell 25 is welded to the top of the ventilation shell 23, and a cooling copper pipe 26 is installed in the inner cavity of the ventilation shell 25.

[0037] Brief description of usage: When fixing the material during cutting, the user places the material to be cut at the bottom of the inner cavity of the support body 1, in contact with the ventilation shell 25. The user then starts the motor 3, which drives the bidirectional threaded rod 4 to rotate. Simultaneously, the rotation of the bidirectional threaded rod 4 causes the threaded sleeve and movable plate connected to it to move towards the center of the support body 1. Once the positioning plate 6 has engaged the material to be cut, the user turns off the motor 3 and rotates the knob 17 to rotate the bidirectional threaded rod 18. As the bidirectional threaded rod 18 rotates, it also causes the movable plate 19 to fix both sides of the material. This setup allows the material to be fixed during laser cutting. The knob 17, bidirectional threaded rod 18, and movable plate 19 fix both sides of the material, allowing the user to control the material during cutting. The two sides are clamped to further fix the position of the material when it is cut by the laser head 8. The positioning frame 20 and the anti-slip plate 21 are set to fix the moving position of the support body 1. When the user cuts the material through the support body 1, the position of the support body 1 is fixed to prevent the position of the support body 1 from shifting during cutting. The anti-slip plate 22 is set to fix the rotation angle of the anti-slip plate 21. When the anti-slip plate 21 is idle, its position is fixed to prevent the position of the anti-slip plate 21 from rotating when the support body 1 is moved due to the connection between the anti-slip plate 21 and the positioning frame 20. The ventilation shell 23, the fan 24, the ventilation shell 25 and the cooling copper pipe 26 are set to cool the material. The overall temperature of the material is maintained when the laser cutting machine cuts the material, so as to avoid deformation of the material when the laser cuts the material.

[0038] Example 2:

A positioning plate 6 is located on the front side of the locking plate 9. Fixing plates 10 are movably connected to both sides of the locking plate 9 via pins. A retaining shell 11 is fitted between the opposite sides of the two fixing plates 10. Positioning rods 12 are welded to opposite sides of the two fixed plates 10. A spring 13 is welded to the rear side of the positioning rod 12. A movable rod 14 is welded to the rear side of the spring 13. The inner cavity of the movable rod 14 is sleeved with the positioning rod 12. A retaining plate 15 is welded to the front side of the movable rod 14. The front sides of the two retaining plates 15 are welded to the inner cavity of the retaining shell 11. A retaining frame 16 is provided on the rear side of the retaining shell 11. The rear side of the retaining frame 16 passes through the second retaining plate 30 and engages with the first retaining plate 9.

[0040] Furthermore, locking rods 27 are welded to both sides of the top of the positioning plate 6, and the top of the locking rods engages with the inner cavity of the connecting plate 7.

[0041] Furthermore, two fixing rods 29 are welded to the top and bottom of the rear side of the retaining shell 11. The inner cavity of the fixing rod is fitted with a second locking rod 28, and the rear side of the second locking rod 28 is welded to the fixing plate 10.

[0042] Brief description of the usage process: When the laser head 8 needs to be disassembled and repaired, the user pulls the retaining shell 11 to drive the movable rod 14 to compress the spring 13. After the retaining shell 11 moves to the designated position, the user drives the fixing plate 10 to move in a circle through the shaft pin. When the fixing plate 10 moves to the designated position, the user disengages the retaining bracket 16 from the locking plate 9. Then, the user disengages the positioning plate 6 from the locking plate 9. This setting allows for quick disassembly of the laser head 8 when the user needs to repair it. By setting the locking rod 27, the movement position of the positioning plate 6 is limited, which makes it easy for the positioning plate 6 to align with the locking plate 9 after the laser head 8 is repaired, preventing the position of the positioning plate 6 from shifting during installation. By setting the locking rod 28, the movement position of the retaining shell 11 is fixed, preventing the retaining shell 11 from separating from the fixing plate 10 when the retaining shell 11 drives the fixing plate 10 to move in a circle.
