Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to an angle adjustment mechanism for a support plate for laser cutting and engraving. Background Technology

[0002] Laser cutting and engraving is a processing technology that uses a high-energy laser beam to precisely cut or engrave the surface of materials. Computer control of the laser path and parameters enables high-precision and high-efficiency processing. It mainly includes: a laser generator: producing a high-energy laser beam (such as a CO2 laser, fiber laser, or semiconductor laser); a control unit: computer software (such as CAD / CAM) controlling parameters such as laser path, power, and speed; a motion unit: a mechanical platform (such as XY-axis guides or rotary axes) enabling precise movement of the laser head; a worktable: a platform supporting the processed material; a cooling unit: preventing the laser from overheating (such as water cooling or air cooling); and an auxiliary gas unit: blowing away molten slag (such as air, nitrogen, or oxygen) to improve cutting quality.

[0003] The structure of the platform mainly includes honeycomb support plates and blade support plates. Honeycomb type is suitable for processing thin plates, fine carving or fragile materials, while blade type is suitable for processing thick metal plates, large-format materials or materials that require air-assisted cutting, thus achieving diversified processing needs.

[0004] In the existing technology, most laser cutting machines support the replacement of the stage, and users can switch between honeycomb or blade stage according to different tasks. However, the current stage is characterized by its large size and heavy weight, making replacement difficult and affecting the performance. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the difficulty and cumbersome switching between honeycomb and blade-type platforms in the existing technology, and to propose an angle adjustment mechanism for the platform support plate of laser cutting and engraving.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser cutting and engraving stage support plate angle adjustment mechanism includes a frame and multiple sets of elongated support bars. Each support bar has a first working surface and a second working surface, with the area of ​​the first working surface being larger than that of the second working surface. The frame has an installation area, and limit portions are provided on both sides of the inner wall of the installation area. A rotating shaft is fixedly provided at both ends of each support bar, and the rotating shaft is rotatably connected to the limit portion. A plate is oscillating within the limit portion. One end of the rotating shaft extending into the limit portion is rotatably connected to the plate via a crankshaft. A driving part for driving the plate to oscillate is provided within the frame. When the plate oscillates, the first working surface and the second working surface switch between each other.

[0008] To facilitate the rotation of the drive support bar, preferably, the drive unit includes a motor fixedly installed in the frame, a disk fixedly installed at the output end of the motor, an eccentric shaft fixedly installed on the disk, and one end of the plate being rotatably connected to the eccentric shaft through a connecting plate.

[0009] To facilitate the installation of the support strip, preferably, the limiting part includes a first limiting plate and a second limiting plate, which are respectively fixedly disposed on the inner walls of both sides of the installation area. The first limiting plate has a rotating hole, and the second limiting plate has a corresponding rotating groove. The rotating shaft is rotatably disposed in the rotating hole and the rotating groove, and the crankshaft is fixedly connected to one end of the rotating shaft that extends into the rotating groove.

[0010] Furthermore, the depth of the rotating groove is greater than or equal to the diameter of the rotating shaft.

[0011] Furthermore, an L-shaped cover plate is detachably installed on the second limiting plate, with one end of the cover plate abutting against the end face of the rotating slot.

[0012] In order to allow the crankshaft to be detachably connected to the plate, preferably, a washer and a retaining spring are sequentially provided at the end of the crankshaft that passes through the plate.

[0013] Preferably, the first working face has mesh openings.

[0014] Preferably, the first working surface and the second working surface are perpendicular to each other.

[0015] Preferably, two sets of limit switches are fixedly installed inside the frame, and a rod is fixedly installed at the other end of the plate. When the plate swings, the rod abuts against the trigger ends of the two sets of limit switches respectively.

[0016] Compared with the prior art, this utility model provides an angle adjustment mechanism for a laser cutting and engraving stage support plate, which has the following advantages:

[0017] 1. The laser cutting and engraving stage support plate angle adjustment mechanism has a support bar that is rotated within the frame. The support bar has a first working surface and a second working surface. By driving the support bar to rotate, two working states can be switched, namely, the switch between honeycomb type and blade type stage. The switching is convenient and fast, which can improve work efficiency.

[0018] 2. The laser cutting and engraving platform support plate angle adjustment mechanism uses two sets of limit switches fixed on the frame. When the motor drives the plate to swing and switch the working state of the support bar, the rod will disengage from the trigger end of the current set of limit switches and move towards the trigger end of the other set of limit switches. When the rod abuts against the trigger end of the other set of limit switches, it indicates that the support bar has rotated by a degree, completing the switching of the working state. The motor then stops running, ensuring accurate switching of the working state of the support bar and improving the usage effect.

[0019] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model has a support bar that is rotatably arranged within the frame. The support bar has a first working surface and a second working surface. By driving the support bar to rotate, two working states can be switched, namely, the switch between the honeycomb type and the blade type platform. The switching is convenient and fast, which can improve work efficiency. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0031] Reference Figures 1-8A laser cutting and engraving stage support plate angle adjustment mechanism includes a frame 1, which has a rectangular structure, and multiple sets of elongated support bars 2. The support bars 2 are arranged in two to fifteen sets, preferably fifteen sets, and are equidistantly distributed. Each support bar 2 has a first working surface 201 and a second working surface 202, meaning it has two working states. The area of ​​the first working surface 201 is larger than the area of ​​the second working surface 202. Mesh holes are formed on the end face of the first working surface 201. The mesh holes can be triangular, rectangular, hexagonal, or circular, etc. Here, a rectangular structure is preferred. That is, when the first working surface 201 is used to support the workpiece, it forms a honeycomb stage; when the second working surface 202 is used to support the workpiece, it forms a blade-type stage. An installation area, also rectangular, is located in the middle of the frame 1. The structure features limiting parts on both inner walls of the installation area. A rotating shaft 203 is fixedly installed at both ends of the support bar 2, rotatably connecting the rotating shaft 203 to the limiting part. A plate 3 is oscillating within the limiting part. One end of the rotating shaft 203 extending into the limiting part is rotatably connected to the plate 3 via a crankshaft 204. Here, a washer and a retaining ring are sequentially installed at the end of the crankshaft 204 passing through the plate 3, meaning the crankshaft 204 is detachably connected to the plate 3 via the retaining ring. A driving part for driving the plate 3 to oscillate is provided within the frame 1. When the plate 3 oscillates, the first working surface 201 and the second working surface 202 switch between each other, i.e., switching between a honeycomb structure and a blade-strip structure. Furthermore, the first working surface 201 and the second working surface 202 are perpendicular to each other. At this time, driving the support bar 2 to rotate 90 degrees forward and backward achieves the switching between the first working surface 201 and the second working surface 202, making the transition convenient and improving the usage effect.

[0032] In use, a support bar 2 is provided inside the frame 1 and rotates. The support bar 2 is provided with a first working surface 201 and a second working surface 202. By driving the support bar 2 to rotate, the two working states can be switched, that is, the switch between the honeycomb type and the blade type platform. The switching is convenient and fast, which can improve work efficiency.

[0033] Reference Figure 4 and Figure 5 Here, we design the drive unit to have a motor 4 fixedly installed inside the frame 1. The motor 4 is preferably a servo motor 4. A disc is fixedly installed at the output end of the motor 4, and an eccentric shaft is fixedly installed on the disc. One end of the plate 3 is rotatably connected to the eccentric shaft through the connecting plate 301. In use, the disc is driven to rotate by the motor 4, and then the plate 3 is oscillating through the eccentric shaft and the connecting plate 301. At this time, the crankshaft 204 can swing back and forth around the axis of the rotating shaft 203 under the drive of the plate 3, realizing the switching of working state and improving the use effect.

[0034] Reference Figures 1-4 , Figure 7 , Figure 8 Here, the limiting part is designed as a first limiting plate and a second limiting plate, which are fixedly installed on the inner walls of both sides of the installation area. A rotating hole 103 is provided on the first limiting plate, and a corresponding rotating groove 102 is provided on the second limiting plate. The rotating shafts 203 at both ends of the support bar 2 are rotatably installed in the rotating hole 103 and the rotating groove 102, respectively. Moreover, the crankshaft 204 is fixedly connected to one end of the rotating shaft 203 extending into the rotating groove 102. In use, by providing a rotating hole 103 on the first limiting plate and a rotating groove 102 on the second limiting plate, not only can... Limiting the support bar 2 also ensures its reliable rotation; and the depth of the rotation groove 102 is greater than or equal to the diameter of the rotating shaft 203, preferably equal to the diameter of the rotating shaft 203. At this time, an L-shaped cover plate 101 is detached and installed on the second limiting plate. The cover plate 101 is detached and installed on the second limiting plate by screws. One end of the cover plate 101 abuts against the end face of the opening of the rotation groove 102, thereby restricting the rotating shaft 203 with the crankshaft 204 within the rotation groove 102. This facilitates limiting the support bar 2, and also makes it easier to install and remove the support bar 2, thus improving the performance.

[0035] Reference Figure 4 and Figure 5 Two sets of limit switches 5 are fixedly installed inside the frame 1, and a rod 302 is fixedly installed at the other end of the plate 3. When the plate 3 swings, the rod 302 abuts against the trigger ends of the two sets of limit switches 5 respectively. In use, by fixing two sets of limit switches 5 on the frame 1, when the motor 4 drives the plate 3 to swing and switch the working state of the support bar 2, the rod 302 will disengage from the trigger end of the current set of limit switches 5 and move towards the trigger end of the other set of limit switches 5. When the rod 302 abuts against the trigger end of the other set of limit switches 5, it means that the support bar 2 has rotated 90 degrees and completed the switching of the working state. The motor 4 stops running, which can ensure the accurate switching of the working state of the support bar 2 and improve the use effect.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
