Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting device technology, specifically a laser cutting device for excavator parts production. Background Technology
[0002] Excavators are heavy machinery widely used in civil engineering, mining, construction sites and other fields. The production of excavator parts requires the use of laser cutting devices to cut the raw materials.
[0003] In the existing technology, laser cutting equipment usually consists of a machine tool, a worktable, a cutting head, a cooler, and a beam transmission component. The worktable is located at the top center of the machine tool and has a large number of holes. During laser cutting, the waste generated during cutting leaks from the holes into a receiving box in the machine tool. After cutting is completed, the receiving box is removed from the machine tool, and the waste can then be recycled.
[0004] However, the design of the receiving box in the existing technology cannot clean up the waste in real time. When the waste accumulates too high in one place, it will hinder the production of excavator parts. At this time, it is necessary to stop the machine immediately for cleaning, which will seriously affect the production efficiency of excavator parts. Utility Model Content
[0005] The purpose of this invention is to provide a laser cutting device for the production of excavator parts, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting device for excavator parts production, comprising: a machine tool, a worktable at the top of the machine tool, a transmission wheel bracket fixed on the surface of the machine tool, a roller rotatably connected to the surface of the transmission wheel bracket, a conveyor belt on the surface of the roller, a scraper frame mounting seat fixed on the surface of the transmission wheel bracket, a scraper frame on the surface of the scraper frame mounting seat, a scraper fixed on the surface of the scraper frame, the scraper abutting against the surface of the conveyor belt, and a quick-release assembly between the scraper frame mounting seat and the scraper frame.
[0007] Preferably, the surface of the machine tool is provided with a conveyor belt opening, the conveyor belt is rotatably connected in the conveyor belt opening, and the conveyor belt opening is located below the worktable.
[0008] Preferably, two sets of transmission wheel supports are provided at one end of the machine tool, and the two sets of transmission wheel supports are symmetrically distributed about the conveyor belt. A motor is fixed on the surface of one set of transmission wheel supports, and a key connection is provided between the transmission shaft of the motor and the roller.
[0009] Preferably, the quick-assembly assembly includes: a limit rod mounting groove, a limit groove, and a limit rod. The limit rod mounting groove is formed on the surface of the scraper frame, and the limit groove is formed on the surface of the scraper frame mounting base. One end of the limit rod is movably inserted into the limit rod mounting groove, and the other end of the limit rod is movably inserted into the limit groove. Both the limit rod mounting groove and the limit groove are rectangular groove structures, and the limit rod is a rectangular rod structure.
[0010] Preferably, a limiting spring is fixed to one end of the limiting rod that extends into the limiting rod mounting groove, and the other end of the limiting spring is fixed to the inner wall of the limiting rod mounting groove.
[0011] Preferably, a push rod hole is provided on the surface of the scraper frame mounting base. The push rod hole communicates with the limiting groove. A push rod is movably inserted into the push rod hole. The push rod has an "I" shaped rod structure. One end of the push rod extends into the limiting groove, and the other end of the push rod extends out from the push rod hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The laser cutting device for excavator parts production proposed in this utility model allows the waste generated during the cutting process to fall through the holes in the workbench and onto the surface of the conveyor belt. The waste is then transported out of the conveyor belt opening by the conveyor belt. The scraper is placed at an angle, with one end of the scraper against the surface of the conveyor belt being higher and the other end away from the conveyor belt being lower. When the waste passes through the angled scraper, it is scraped off the conveyor belt and slides down with the scraper, eventually falling into the waste collection box. This achieves real-time cleaning of the waste and prevents the accumulation of waste from affecting the production efficiency of excavator parts. At the same time, (8) can be easily replaced by quick disassembly and assembly components. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a laser cutting device for excavator parts production, comprising: a machine tool 1, a worktable 2 at the top of the machine tool 1, a transmission wheel bracket 5 fixed on the surface of the machine tool 1, a roller 7 rotatably connected to the surface of the transmission wheel bracket 5, a conveyor belt 4 on the surface of the roller 7, a scraper frame mounting seat 9 fixed on the surface of the transmission wheel bracket 5, a scraper frame 10 on the surface of the scraper frame mounting seat 9, a scraper 8 fixed on the surface of the scraper frame 10, the scraper 8 abutting against the surface of the conveyor belt 4, a quick-release assembly between the scraper frame mounting seat 9 and the scraper frame 10, a conveyor belt opening 3 on the surface of the machine tool 1, the conveyor belt 4 rotatably connected in the conveyor belt opening 3, and the conveyor belt opening 3 being located below the worktable 2.
[0021] In actual use, a conveyor belt opening 3 is made on the surface of machine tool 1, a transmission wheel bracket 5 is fixed on the surface of machine tool 1, a roller 7 is rotatably connected to the surface of the transmission wheel bracket 5, and a conveyor belt 4 is set on the surface of the roller 7. The conveyor belt 4 is rotatably connected in the conveyor belt opening 3. Before laser cutting excavator parts, a waste collection box is placed under the scraper 8. Then, the workpiece is placed on the top of the worktable 2 for cutting. The waste generated during the cutting process falls from the hole of the worktable 2 and onto the surface of the conveyor belt 4. It is then transported out from the conveyor belt opening 3 by the conveyor belt 4. The scraper 8 is placed at an angle, with one end of the scraper 8 against the surface of the conveyor belt 4 being higher and the other end away from the conveyor belt 4 being lower. When the waste passes through the inclined scraper 8, it is scraped off the conveyor belt 4 and slides down with the scraper 8, eventually falling into the waste collection box. This achieves real-time cleaning of waste and prevents the production efficiency of excavator parts from being affected by the accumulation of waste.
[0022] Example 2: Based on Example 1, in order to drive the conveyor belt 4 to operate, two sets of transmission wheel brackets 5 are provided at one end of the machine tool 1. The two sets of transmission wheel brackets 5 are symmetrically distributed about the conveyor belt 4. A motor 6 is fixed on the surface of one set of transmission wheel brackets 5, and a key connection is provided between the transmission shaft of the motor 6 and the roller 7.
[0023] A motor 6 is fixed on one of the drive wheel brackets 5. A key connection is provided between the drive shaft of the motor 6 and the roller 7. When the motor 6 is powered on, the rotation of the drive shaft of the motor 6 can drive the roller 7 to rotate through the key connection, thereby causing the roller 7 to drive the conveyor belt 4 to rotate.
[0024] Example 3: Based on Example 2, to facilitate the replacement of scraper 8, a quick-release assembly includes: a limit rod mounting groove 11, a limit groove 12, and a limit rod 13. The limit rod mounting groove 11 is formed on the surface of the scraper frame 10, and the limit groove 12 is formed on the surface of the scraper frame mounting base 9. One end of the limit rod 13 is movably inserted into the limit rod mounting groove 11, and the other end of the limit rod 13 is movably inserted into the limit groove 12. Both the limit rod mounting groove 11 and the limit groove 12 are rectangular groove structures. The positioning rod 13 has a rectangular rod structure. One end of the positioning rod 13 extends into the positioning rod mounting groove 11 and is fixed with a positioning spring 14. The other end of the positioning spring 14 is fixed to the inner wall of the positioning rod mounting groove 11. A push rod hole 15 is provided on the surface of the scraper frame mounting seat 9. The push rod hole 15 is in communication with the positioning groove 12. A push rod 16 is movably inserted into the push rod hole 15. The push rod 16 has an "I" shaped rod structure. One end of the push rod 16 extends into the positioning groove 12, and the other end of the push rod 16 extends out from the push rod hole 15.
[0025] The scraper 8 rests against the surface of the conveyor belt 4. Therefore, the friction between the scraper 8 and the conveyor belt 4 causes the scraper 8 to gradually wear down, resulting in a gap between the conveyor belt 4 and the scraper 8. When the gap becomes large enough to allow waste residue to pass through, some waste residue will adhere to the surface of the conveyor belt 4 and cannot be scraped off by the scraper 8, thus preventing recycling. Therefore, the scraper 8 needs to be replaced. When the scraper 8 needs to be replaced, the push rod 16 is pressed into the push rod hole 15. The push rod 16 pushes the limiting rod 13, causing the limiting rod 13 to move from the limiting position. Remove the old scraper 8 from the groove 12, and then remove the old scraper 8 and scraper frame 10 together from the surface of the scraper frame mounting base 9. When installing the new scraper 8, press the limiting rod 13 on the new scraper 8 completely into the limiting rod mounting groove 11, and the limiting spring 14 will be compressed. Then place the scraper frame 10 on the new scraper 8 between the two sets of scraper frame mounting bases 9. When the limiting rod mounting groove 11 is aligned with the limiting groove 12, the limiting spring 14 will push one end of the limiting rod 13 into the limiting groove 12, and the replacement of the scraper 8 can be completed.
[0026] In actual use, a conveyor belt opening 3 is made on the surface of machine tool 1, a transmission wheel bracket 5 is fixed on the surface of machine tool 1, a roller 7 is rotatably connected to the surface of the transmission wheel bracket 5, and a conveyor belt 4 is set on the surface of the roller 7. The conveyor belt 4 is rotatably connected in the conveyor belt opening 3. Before laser cutting excavator parts, a waste collection box is placed under the scraper 8, and then the workpiece is placed on the top of the worktable 2 for cutting. The waste generated during the cutting process falls from the hole of the worktable 2 onto the surface of the conveyor belt 4 and is discharged from the conveyor belt opening 3 by the conveyor belt 4. After transportation, the scraper 8 is placed at an angle, with one end of the scraper 8 higher than the surface of the conveyor belt 4 and the other end lower than the surface of the conveyor belt 4. When the waste passes over the inclined scraper 8, it is scraped off the conveyor belt 4 and slides down with the scraper 8, eventually falling into the waste collection box. This achieves real-time cleaning of the waste and prevents the accumulation of waste from affecting the production efficiency of excavator parts. A motor 6 is fixed on one of the drive wheel brackets 5. The drive shaft of the motor 6 is connected to the roller 7 by a key. When the motor 6 is powered on, the drive shaft of the motor 6 rotates. The roller 7 is driven to rotate via a key connection, which in turn drives the conveyor belt 4. The scraper 8 rests against the surface of the conveyor belt 4, and the friction between the scraper 8 and the conveyor belt 4 causes the scraper 8 to wear down gradually, resulting in a gap between the conveyor belt 4 and the scraper 8. When the gap becomes large enough to allow waste residue to pass through, some waste residue will stick to the surface of the conveyor belt 4 and cannot be scraped off by the scraper 8, thus making it unrecyclable. Therefore, the scraper 8 needs to be replaced. When the scraper 8 needs to be replaced, the push rod 16 is pressed into the push rod hole 15, and the push rod 16 pushes the limit... The positioning rod 13 is moved out of the limiting groove 12, and then the old scraper 8 and scraper frame 10 can be removed from the surface of the scraper frame mounting base 9. When installing the new scraper 8, the limiting rod 13 on the new scraper 8 is fully pressed into the limiting rod mounting groove 11, the limiting spring 14 is compressed, and then the scraper frame 10 on the new scraper 8 is placed between the two sets of scraper frame mounting bases 9. When the limiting rod mounting groove 11 is aligned with the limiting groove 12, the limiting spring 14 pushes one end of the limiting rod 13 into the limiting groove 12, and the replacement of the scraper 8 is completed.
