Description

Technical Field

[0001] This utility model relates to the technical field of laser tube cutting machine accessories, and in particular to a side-mounted bed for a laser tube cutting machine. Background Technology

[0002] A laser tube cutting machine is a device that uses a laser beam to process tubes. Its core technology integrates photoelectric conversion, dynamic beam control, and thermodynamic effects to focus a high-intensity laser beam onto the surface of the tube, heating the surface to a high temperature. Then, the machine's motion system uses the laser beam to cut along the cutting trajectory of the tube.

[0003] Side-mounted bed is a structure derived from laser tube cutting machines to meet the needs of processing long tubes and compact layout. It solves the pain points of traditional horizontal beds, such as large footprint and bending deformation of long tubes. The sliding mechanism in common side-mounted beds often uses linear guides, and the internal part mostly uses ball linear guides. However, in actual use, we have found that ball linear guides have low load-bearing capacity, and dust has a significant impact on the balls, which greatly affects the service life of the entire bed.

[0004] Furthermore, the guide rail is the core guiding component of the laser cutting machine. Currently, laser tube cutting machines and side-mounted beds lack a structure to clean the dust on the guide rail. If smoke, dust, or metal shavings generated during cutting accumulate on its surface for a long time, scratches or corrosion points will form on the guide rail surface, further damaging the straightness of the guide rail, causing the cutting path to deviate, and affecting the normal operation of the laser tube cutting machine.

[0005] To address the aforementioned problems, a side-mounted bed for laser tube cutting machines was specifically designed. Utility Model Content

[0006] The purpose of this invention is to provide a side-mounted bed for a laser tube cutting machine to solve the problems mentioned in the background art regarding the poor load-bearing capacity, weak stability, and lack of dust cleaning on the guide rails.

[0019] A cleaning assembly 8 is fixedly connected above each slide rail 4 on one side of the support frame 3. Each cleaning assembly 8 includes a mounting shell 81 bolted to the side wall of the housing 51. A screw 82 is screwed to the top of the mounting shell 81, and a drive block 83 is rotatably connected to the bottom of the screw 82. A connecting rod is provided between the drive block 83 and the mounting shell 81. One end of the connecting rod is slidably connected to a groove in the mounting shell, and the other end is welded to the drive block 83. A first wiping plate 84 for cleaning the top surface of the slide rail is inserted into the bottom of the drive block 83. The two ends of the drive block 83... A side wall cleaning unit 85 for cleaning both sides of the slide rail 4 is provided. The mounting shell 81 is fixedly connected to the housing 51, so that the entire cleaning assembly 8 can move synchronously with the roller walking assembly 5. By rotating the knob on the top of the screw 82, the screw 82 is lowered, which drives the drive block 83 to lower. A cleaning cloth is provided on the first wiping plate 84 on the drive block 83. It can be fixed by Velcro or adhesive. The first wiping plate 84 is fixed to the drive block 83 by plugging and follows the drive block 83 to lower, and then contacts the top surface of the slide rail 4.

[0020] Furthermore, the sidewall cleaning unit 85 includes slots 851 formed on both sides of the drive block 83 and connecting shafts 852 slidably connected to the slots 851 on both sides of the drive block 83. The two connecting shafts 852 can move horizontally in the slots. A limit hole 853 is formed on the side of the slot 851 away from the connecting shaft 852. A first wedge 854 is symmetrically arranged at the opposite end of each connecting shaft 852. A spring 856 is arranged inside the slot at the other end of each connecting shaft 852. A second wedge 856 is inserted into the first wedge 854. The wiping plate 855 and spring 856 are equipped with a limiting rod 857 inside.

It is first inserted into the limiting hole 853, and then a stop block is screwed to the outside of the limiting hole 853 to block the internal limiting block. A second wedge 858 is slidably connected between the first wedge 854 and the mounting shell 81. The second wedge 858 is welded to the inner wall of the mounting shell 81.

[0021] Working principle: When using this utility model, the first roller 42 is rolled and connected to the top of the slide rail, and the two second rollers 53 are rolled and connected to both sides of the slide rail 4 to support and run the entire chuck 2. Compared with the ball linear guide, the roller guide is more stable, has a stronger load-bearing capacity, and a longer service life of the bed. When you want to clean the slide rail 4 after using it for a period of time, you can turn the knob to drive the screw 82 to rotate, so that the screw 82 moves downward in the mounting shell 81, pushing the drive block 83 down so that the first wiping plate 84 fits against the top of the slide rail 4. The cleaning operation is completed during the movement. During the descent, because the inclined surfaces of the first wedge 854 and the second wedge 858 are in contact with each other, the fixed setting of the second wedge 858 will drive the first wedge 854 to move closer to the slide rail 4 until the second wiping plate 855 fits against both sides of the slide rail 4. The cleaning is completed during the movement. When the second wiping plate 855 is retracted, the drive block 83 moves upward and the elastic force of the spring 856 causes the first wedge 854 to move towards the second wedge 858, gradually moving away from the slide rail 4.
