Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment, specifically a laser cutting device for processing long shaft parts. Background Technology

[0002] Long shaft parts are a type of rotating shaft parts in mechanical engineering that are much longer than their diameter. They are mainly used to support transmission components, transmit torque, and bear loads. To meet processing requirements, the long metal raw materials of long shaft parts need to be cut. Laser cutting is usually used for processing, which has significant advantages such as no tool wear, high flexibility, and good cut quality.

[0003] When laser cutting long shaft parts, the long rod material is first transported to the bottom of the laser cutter via a conveyor table. The laser cutter then cuts the outer side of the long rod material. Existing laser cutters have a movable baffle installed on the conveyor table. The movable baffle is placed against the end of the long rod material before the laser cutter cuts it. Although this can achieve a fixed length cut, the cut end of the long rod material is very hot and has a lot of burrs. If the long rod material is placed directly against the outer side of the movable baffle, it is easy for the long rod material to become skewed or stick to the movable baffle, affecting subsequent laser cutting processes.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram shows a laser cutting device for processing long shaft parts, including a device base 1 and a roller conveyor 2 fixedly installed on the top of the device base 1. Two symmetrically distributed support frames 3 are fixedly installed on the top of the device base 1, and an electric slide table 4 is fixedly installed between the two support frames 3. A laser cutter 5 is installed on the outside of the electric slide table 4. The roller conveyor 2 can convey long rod materials, move the long rod materials to below the laser cutter 5, and cause the electric slide table 4 to drive the laser cutter 5 to move longitudinally, so that the laser cutter 5 can cut the long rod materials. The fixed rod mechanism includes multiple partitions 6 equidistantly arranged above the roller conveyor table 2. These partitions 6 can separate and position multiple long rods of raw material. The fixed rod mechanism also includes two mounting plates 9 symmetrically installed on the top of the roller conveyor table 2. Two symmetrically distributed fixed rods 10 are fixedly installed between the two mounting plates 9. Two symmetrically arranged first sleeve plates 11 are fixedly installed at the bottom of the partitions 6, and each first sleeve plate 11 is fitted onto the outside of the two fixed rods 10, so that the fixed rods 10 provide support for the first sleeve plates 11, and the two first sleeve plates 11 provide support for the mounting plates 9. Support tubes 12 are fixedly installed on the outside of the first sleeve plates 11. Support tube 12 is sleeved on the outside of fixed rod 10, providing auxiliary support for the first sleeve plate 11. A limiting block 13 is fixedly installed between the two fixed rods 10, with the outer side of the limiting block 13 contacting the outer side of the two support tubes 12 closest to the rightmost end of the fixed rod 10. A movable push plate 14 is sleeved between the two fixed rods 10, with the outer side of the movable push plate 14 contacting the outer side of the two support tubes 12 closest to the leftmost end of the fixed rod 10. Two first electric push rods 15 are installed between the side of the movable push plate 14 away from the support tubes 12 and the outer side of the mounting plate 9. Multiple springs 16 are equidistantly distributed on the outside of the fixed rods 10. The first plate 6 and the first plate 11 are staggered, and the spring 16 is fixedly installed between adjacent first plates 11. The roller conveyor table 2 can convey multiple long rod materials to the space between adjacent partition plates 6. Two first electric push rods 15 can push the movable push plate 14 to move along the outside of the fixed rod 10, so that the movable push plate 14 pushes two adjacent support tubes 12. The support tube 12 pushes the spring 16 through the corresponding first plate 11, so that the spring 16 pushes the next first plate 11, so that each first plate 11 can move along the outside of the fixed rod 10 to achieve clamping and positioning of long rod materials, which makes it convenient for the operator to start the laser cutter 5 to cut multiple materials at the same time. Long rod materials are cut. Three U-shaped frames 36 are fixedly installed on the top of the roller conveyor table 2. Multiple guide plates 40 are fixedly installed between the three U-shaped frames 36, and the number of guide plates 40 is the same as the number of partition plates 6. The operator can place multiple long rod materials between adjacent guide plates 40 to prevent collisions during the conveying process. The bottom of the mounting plate 9 has a groove corresponding to the roller on the roller conveyor table 2, so that the mounting plate 9 can avoid the roller. The top of the mounting plate 9 has an L-shaped structure and two assembly holes, so that the mounting plate 9 can be assembled on the roller conveyor table 2.

[0022] Example 2: Please refer to Figures 3-8This embodiment further illustrates Example 1. The locking mechanism shown in the figure includes four pressure rollers 7 symmetrically arranged on the outside of the partition 6. The pressure rollers 7 can abut against the outside of the long rod material. The locking mechanism also includes a U-shaped seat 17 arranged on the outside of the pressure rollers 7. The U-shaped seat 17 is fixedly installed on the outside of the partition 6. Positioning rods 18 are fixedly installed on the top and bottom of the pressure rollers 7. The positioning rods 18 are rotatably installed on the inside of the U-shaped seat 17. Two symmetrically distributed anti-slip collars 19 are fixedly installed on the outside of the pressure rollers 7, so that the partition 6 can drive the pressure rollers 7 to move through the U-shaped seat 17, so that the two anti-slip collars 19 on the outside of the pressure rollers 7 abut against the outside of the long rod material to prevent slippage. An insert plate 20 is fixedly installed on the outside of the positioning rod 18. Multiple sliders 21 are arranged symmetrically at the center. A plug block 22 is fixedly installed on the side of each slider 21 near the plug plate 20. The outer side of the plug plate 20 has slots for the plug block 22 to be inserted into, and the number of slots is twice the number of plug blocks 22. Two cavities are formed on the inner side of the U-shaped seat 17. Two plug plates 20 are located inside the two cavities respectively. A gear plate 23 is rotatably installed inside the cavity. A pulley 24 is rotatably installed on the side of the slider 21 near the gear plate 23. An arc-shaped groove is formed on the outer side of the gear plate 23 for the pulley 24 to slide within a limited position. A fixed plate 25 is fixedly installed inside the cavity. A slide rod 26 is fixedly installed on the side of the slider 21 near the fixed plate 25. A long groove is formed on the surface of the fixed plate 25 for the slide rod 26 to be inserted into within a limited position. An optical axis with a sliding through-rod 26 is fixedly installed on the inner side. When the gear plate 23 rotates, it can push the pulley 24 to move through the arc groove, so that the pulley 24 drives the slide rod 26 on the slider 21 to move along the long groove on the fixed plate 25 and the outer side of the optical axis. The slider 21 can move linearly, so that the slider 21 pushes the insert block 22 into the slot of the insert plate 20, thereby locking the insert plate 20. The insert plate 20 can lock the pressure roller 7 through the positioning rod 18. The pressure roller 7 can lock the long rod material through two anti-slip collars 19, so that the laser cutter 5 can cut the long rod material smoothly. A rack plate 27 that cooperates with the gear plate 23 is slidably installed on the inner side of the cavity. A pull plate 28 is fixedly installed between two vertically corresponding rack plates 27, and the pull plate 28 is fixedly installed between them. Plate 28 is located outside the U-shaped seat 17, allowing the operator to pull the rack plate 27 via the pull plate 28, causing the rack plate 27 to drive the gear disc 23 to rotate, thereby locking and unlocking the insert plate 20. A groove is provided on the side of the slider 21 away from the insert block 22, and a guide block 37 is slidably installed inside the groove. The guide block 37 is fixedly installed inside the cavity. When the slider 21 moves, it can move along the outside of the guide block 37, improving the smoothness of the slider 21's movement. A positioning ring 38 is fixedly installed on the side of the gear disc 23 away from the insert plate 20. An annular cavity is provided inside the cavity for the positioning ring 38 to rotate, providing positioning for the gear disc 23 and ensuring the smoothness of its rotation. The end of the insert block 22 away from the slider 21 has a trapezoidal structure.Furthermore, the slot opening of the insert plate 20 has a beveled structure, which facilitates the insertion of the insert block 22 into the slot.

[0023] Example 3: Please refer to Figures 3-8 This embodiment further illustrates other embodiments. The synchronization mechanism shown in the figure includes a pull rod 8 slidably installed inside the partition 6. The pull rod 8 can synchronously unlock or lock multiple pressure rollers 7. The synchronization mechanism also includes two slide plates 29 fixedly installed outside the pull rod 8. The slide plates 29 are fixedly connected to the outer sides of two adjacent pull plates 28. The outer side of the partition 6 has a sliding cavity for the pull rod 8 and the slide plates 29 to slide in a limited manner. When the pull rod 8 moves, it can pull the pull plates 28 to move through the slide plates 29. An L-shaped support plate 30 is provided on the top of the partition 6. One end of the L-shaped support plate 30 is fixedly connected to one end of the pull rod 8. A second sleeve plate 31 is fixedly installed on the top of the L-shaped support plate 30. A second electric push rod 32 is fixedly installed on the top of the mounting plate 9. A moving rod 33 is installed between the two second electric push rods 32. The second sleeve plate 31 is sleeved on the moving rod. On the outside of 33, the second electric push rod 32 can push the moving rod 33 to move, so that the moving rod 33 pulls the L-shaped support plate 30 to move through the second sleeve plate 31, realizing the synchronous movement of multiple pull rods 8, which facilitates the synchronous locking and unlocking of multiple pressure rollers 7. Two vertically symmetrically distributed V-shaped plates 34 are fixedly installed at the end of the partition plate 6 away from the L-shaped support plate 30. Multiple equally distributed rollers 35 are rotatably installed between the two V-shaped plates 34, so that the end of the long rod material can enter between the two partition plates 6 along the rollers 35 on the V-shaped plate 34, providing guidance for the long rod material. A sliding column 39 is fixedly installed at the bottom of the L-shaped support plate 30. A sliding groove is opened at the top of the partition plate 6 for the sliding column 39 to be limited and slid, so that the L-shaped support plate 30 can drive the sliding column 39 to move along the inner side of the sliding groove. The sliding column 39 can ensure that the second sleeve plate 31 is attached to the top of the partition plate 6.

[0024] Working principle: First, the operator places multiple long rods of raw material between two guide plates 40, allowing the roller conveyor 2 to separate and transport the long rods. When the end of the long rod contacts the roller 35 on the V-shaped plate 34, the end of the long rod moves along the outside of the roller 35, moving the long rod between two adjacent partitions 6. Multiple long rods are then staggered between the partitions 6. At this time, two first electric push rods 15 are activated, pushing the movable push plate 14 along the outside of the fixed rod 10. The movable push plate 14 then pushes the adjacent partitions... Each support tube 12 pushes a spring 16 via a corresponding first sleeve plate 11. The spring 16 pushes the next first sleeve plate 11, and the remaining first sleeve plates 11 can move synchronously on the outside of the fixed rod 10, compressing the spring 16. The support tube 12 located at the rightmost end of the fixed rod 10 can abut against the limiting block 13, so that each partition plate 6 pushes the outside of the long rod material through the pressure roller 7 on the U-shaped seat 17, and abuts against the long rod material through the two anti-slip collars 19 on its outside, realizing the synchronous positioning of multiple long rod materials. Then, the second electric push rod 32 pushes the moving rod 33 to move, so that... The moving rod 33 pushes the L-shaped support plate 30 along the top of the partition 6 via the second set plate 31. The L-shaped support plate 30 pulls the slide plate 29 via the pull rod 8. The slide plate 29 drives the rack plate 27 to move via the pull plate 28, causing the rack plate 27 to drive the gear plate 23 to rotate. The gear plate 23 pushes the pulley 24 through the arc groove, causing the pulley 24 to drive the slide rod 26 on the slider 21 to move along the long groove on the fixed plate 25 and the outer side of the optical axis. The slider 21 can then push the insert block 22 into the slot of the insert plate 20, thereby locking the insert plate 20. The insert plate 20 is then locked to the pressure roller 7 via the positioning rod 18. The friction between the two anti-slip rings 19 of the pressure roller 7 and the long rod material is used to lock the long rod material. Then, the electric slide table 4 drives the laser cutter 5 to move, so that the laser cutter 5 cuts multiple long rod materials in sequence. Finally, the first electric push rod 15 pulls the movable push plate 14 to reset. The rebound force of the spring 16 is used to release the cut short rod materials from the multiple partitions 6, so that the roller conveyor table 2 can transport the cut short rod materials out and push the long rod materials forward to facilitate the re-cutting of the long rod materials. This achieves the effect of continuously processing multiple long rod materials and improves processing efficiency.
