Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically a laser cutting machine with a protective structure. Background Technology

[0002] Laser cutting technology, with its high precision and efficiency, has become a core method for processing metal and non-metal materials in modern manufacturing. Traditional laser cutting machines typically employ an open or semi-closed structure, which can easily generate high-temperature debris during the cutting process, posing safety hazards. Furthermore, the cutting residue requires manual cleaning, affecting continuous operation efficiency.

[0003] Existing protective devices mostly employ manual opening and closing of covers or simple mechanical interlocking structures, which have significant shortcomings in automation. Manual operation is not only time-consuming and labor-intensive, but also prone to human error leading to incorrect opening and closing of the protective devices, thus increasing safety hazards. In high-precision machining environments, the equipment operates at a fast pace, and manually operated protective devices struggle to keep up with the equipment's speed, resulting in a mismatch between protective functions and the production process. Furthermore, the lack of integration with waste disposal systems leads to a disconnect between protective and cleaning functions, failing to meet the dual requirements of safety and cleanliness in high-precision machining environments.

[0007] The protective assembly includes a protective cover that slides on one side of the machine tool. A sliding plate is fixed to one side of the protective cover, and a rack is fixed to one side of the sliding plate. The rack moves to one side, causing the protective cover and the sliding plate to move along the machine tool, thereby controlling the opening and closing of the protective cover to protect the internal laser cutting process.

[0008] Preferably, the laser cutting assembly further includes two sets of transverse rods fixed to both sides inside the machine tool;

[0009] The horizontal slider is provided in two sets, and both slide through the grooves opened in the two sets of horizontal bars.

[0022] A second bevel gear meshes with one side of a first bevel gear. A transmission screw is fixedly connected to the middle of the second bevel gear, and a movable plate is threaded onto the surface of the transmission screw.

[0023] A connecting plate, which is fixedly connected to one end of a movable plate, and a scraper is slidably connected inside the connecting plate;

[0031] (1) This utility model achieves automatic synchronization of the opening and closing of the protective cover with the cutting process through rack and pinion and spur gear. Before cutting, the cylinder drives the rack to mesh with the spur gear, which drives the sliding plate and the protective cover to close completely, forming a fully enclosed processing space and completely blocking the splashing of debris; after cutting, the reverse drive opens the cover, and the protective action and processing sequence are precisely matched, which significantly improves safety.

[0032] (2) When the protective cover of this utility model is opened and closed, the protective action is converted into the lateral movement of the cleaning component through the bevel gear set and the transmission screw, realizing the automated process of "cleaning when the cover is opened". No additional power source is required. The scraper contacts the workpiece surface through the adaptive component. The scraper is guided to rise and fall by the inclined surface of the auxiliary block. Combined with the spring buffer, it ensures the tight contact of the workpiece surface at different heights, avoids hard contact damage to the workpiece, and improves the scraping efficiency of debris.

Detailed Implementation

[0041] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Example 1

[0043] Please see Figure 1 - Figure 7 This application provides a laser cutting machine with a protective structure, including: a machine tool 1, a laser cutting assembly 5 installed inside the machine tool 1, and a protective assembly 2 provided on the machine tool 1;

[0044] The laser cutting assembly 5 includes a longitudinal slider 54 that is driven to move by a driving member 55, and a laser cutter 56 is fixed to one side of the longitudinal slider 54.

[0045] The protective component 2 includes a protective cover 20 that slides on one side of the machine tool 1. A sliding plate 22 is fixedly connected to one side of the protective cover 20, and a rack 24 is fixedly connected to one side of the sliding plate 22. The rack 24 moves to one side, causing the protective cover 20 and the sliding plate 22 to move along the machine tool 1, thereby realizing the opening and closing control of the protective cover 20 to protect the internal laser cutting process.

[0046] In this embodiment, preferably, the laser cutting assembly 5 further includes two sets of transverse rods 50 fixed to both sides inside the machine tool 1;

[0047] The horizontal slider 51 has two sets, both of which slide through the grooves opened in the two sets of horizontal rods 50.

[0048] Drive component 52 is fixedly connected to one of the sets of transverse rods 50, and drive the transverse slider 51 to move.

[0049] Longitudinal rod 53 is fixed to the inner side of two sets of transverse sliders 51;

[0050] The longitudinal slider 54 moves through a groove opened on the inner side of the longitudinal rod 53.

[0051] It should be noted that the specific components of drive component 1 52 and drive component 2 55 are motor threaded rod drives, which enable the laser cutter 56 to move along the XY axis. Both the laser cutter 56 and the motor are wirelessly transmitted and controlled by a controller (not shown).

[0052] The sliding plate 22 slides through the groove opened in the machine tool 1, which can effectively avoid interference.

[0053] In this embodiment, preferably, the protective component 2 further includes a positioning plate 26 fixed to one side of the machine tool 1.

[0054] A spur gear 25 is rotatably connected to the surface of the positioning plate 26.

[0055] Rack 24, rack 24 meshes with one side of spur gear 25;

[0056] Cylinder 21 is fixed to the surface of machine tool 1, and the output of cylinder 21 is fixed to one end of rack 24.

[0057] In this embodiment, preferably, a filling block 8 is fixedly connected inside the machine tool 1, a support plate 4 is fixedly installed inside the machine tool 1, and a limit post 6 is fixedly installed on the surface of the support plate 4.

[0058] The workpiece 11 is placed on the surface of the support plate 4, and a discharge chute 7 is provided on one side of the support plate 4. A collection box 10 is slidably connected to the bottom of the machine tool 1.

[0059] The collection box 10 is located directly below the discharge chute 7 to facilitate the collection of waste material from the cutting of the workpiece 11.

[0060] It should be noted that multiple sets of limiting posts 6 are symmetrically arranged. The limiting posts 6 are made of rubber material, which gives the limiting posts 6 a certain elasticity so that they can better limit the workpiece 11.

[0061] The height of the limiting post 6 is less than the height of the workpiece 11 to avoid interference when the scraper 31 moves on the surface of the workpiece 11.

[0062] In the implementation process, the workpiece 11 is first placed on the surface of the support plate 4 and limited by the limiting post 6. The cylinder 21 is set up. The output end of the cylinder 21 moves the rack 24. The rack 24 moves and closes the sliding plate 22 and the protective cover 20, so that the machine tool 1 is kept in a fully enclosed state to prevent the waste material from flying out and causing injury when the workpiece 11 is cut.

[0063] The XY axis movement is controlled by drive component 1 52 and drive component 2 55 to enable laser cutter 56 to perform laser cutting on workpiece 11. After cutting is completed, cylinder 21 is reversed. The output end of cylinder 21 moves rack 24, which in turn moves sliding plate 22 and protective cover 20 to open.

[0064] Example 2

[0065] In this embodiment, preferably, a cleaning component 3 is connected to one side of the protective component 2, and multiple sets of adaptation components 9 are installed in the cleaning component 3.

[0066] In this embodiment, preferably, the cleaning component 3 includes a limiting plate 32 fixed to one side of the outside of the machine tool 1;

[0067] The bevel gear 33 rotates on the surface of the limiting plate 32. A drive shaft 34 is fixedly connected to the middle of the bevel gear 33, and the end of the drive shaft 34 away from the bevel gear 33 is fixedly connected to the middle of the spur gear 25.

[0068] Bevel gear 2 35 meshes with one side of bevel gear 1 33. A transmission screw 36 is fixedly connected to the middle of bevel gear 2 35, and a movable plate 37 is threadedly connected to the surface of the transmission screw 36.

[0069] A connecting plate 30 is fixedly connected to one end of a movable plate 37, and a scraper 31 is slidably connected inside the connecting plate 30.

[0070] Two sets of auxiliary blocks 38 are fixed to both sides of one end of the support plate 4.

[0071] It should be noted that the limiting plate 32 and the positioning plate 26 are arranged in parallel, and the two sets of auxiliary blocks 38 are arranged in a triangle and have two sets of the same inclined surfaces, so that the scraper 31 can be adjusted to contact the surface of the workpiece 11 through the inclined surfaces.

[0072] In this embodiment, preferably, the transmission shaft 34 is movably mounted in the middle of the positioning plate 26, the other end of the moving plate 37 slides through the groove opened in the middle of the filling block 8, and the transmission screw 36 is movably connected to one side of the machine tool 1.

[0073] In this embodiment, preferably, the adaptation component 9 includes a lower limiting disk 93 fixed to the top of the scraper 31;

[0074] Connecting post 91 is fixed to the middle of the lower limit plate 93;

[0075] Upper limit plate 90 is fixed to the end of connecting post 91 away from lower limit plate 93;

[0076] Spring 92 is sleeved on connecting post 91. One end of spring 92 is fixed to the surface of lower limit plate 93, and the other end of spring 92 is fixed to the inside of connecting plate 30.

[0077] It should be noted that the connecting column 91 slides on one side of the connecting plate 30, and the upper limit plate 90 can effectively prevent the scraper 31 from falling off.

[0078] During implementation, when the rack 24 moves and opens along with the sliding plate 22 and the protective cover 20, the rack 24 meshes with the spur gear 25. The spur gear 25 rotates, causing the transmission shaft 34 to rotate along the limiting plate 32 and the positioning plate 26. The transmission shaft 34 then rotates the first bevel gear 33, which in turn rotates the second bevel gear 35. The second bevel gear 35 then rotates the transmission screw 36 along the machine tool 1. The rotation of the transmission screw 36 drives the moving plate 37, which moves to one side along the groove opened in the adaptation component 9. As the connecting plate 30 and scraper 31 move along the inclined surface of the auxiliary block 38, the scraper 31 moves upward along the connecting plate 30 and then squeezes the spring 92 through the lower limit plate 93, causing the scraper 31 to retract. When the scraper 31 contacts the surface of the workpiece 11, the counter-pushing force of the spring 92 causes the scraper 31 to quickly adhere to the surface of the workpiece 11 and move with the moving plate 37 to push and clean the surface of the workpiece 11, so that the cutting residue on the surface of the workpiece 11 falls from the discharge chute 7 into the collection box 10. When the rack 24 moves in the opposite direction, it returns to its original position.

[0079] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
