Description

Technical Field

[0001] The utility model relates to the field of profile sawing and milling equipment, in particular to a laser protection device for a laser sawing and milling equipment. Background Art

[0002] Profile sawing and milling equipment is an integrated equipment for sawing and drilling profiles. Some sawing and milling equipment also has a laser for laser scribing, which is mainly used for scribing the middle rail position of door and window profiles. At present, the drilling and milling unit in sawing and milling equipment is mainly a four-head drilling and milling, and the sawing unit is mainly an arbitrary-angle sawing. For example, in the patent CN220347720U, a laser scribing and drilling and milling integrated device for door and window profiles is disclosed. Laser cutting heads are arranged on the left and right sides of a four-head drilling and milling equipment to scribe the profile to meet the requirements of subsequent middle rail installation of the profile. However, in the above technology, the debris ejected during drilling of the four-head drilling and milling equipment is easily deposited on the glass sheet of the laser cutting head, scratching the glass sheet of the laser cutting head and reducing the service life of the laser cutting head. In the prior art, in order to protect the glass sheet of the laser cutting head, operators often cover the laser cutting head with a protective cover when the laser cutting head is not in use, but this is not only inefficient but also has poor operation safety. Summary of the Utility Model

[0003] The glass sheet of the laser cutting head arranged at the four-head drilling and milling device of the existing profile is easily scratched because the debris ejected during drilling of the four-head drilling and milling device is easily deposited on the glass sheet, thereby scratching the glass sheet and reducing the service life of the laser cutting head. At least one aspect or one purpose of the present application can solve the above problems. Specifically, a laser protection device for a laser sawing and milling equipment is designed, and its solution is as follows:

[0004] A laser protection device for a laser sawing and milling equipment is arranged on a drilling and milling equipment. The drilling and milling equipment includes a frame and four drill bit assemblies. The four drill bit assemblies are arranged on the frame through a three-axis motion platform. The operation sequence of the three-axis motion platform is the X-axis, the Z-axis, and the Y-axis, and a through port for the profile to pass through is provided at its center. The four drill bit assemblies are arranged around the through port of the Y-direction moving plate of the three-axis motion platform. The laser protection device includes:

[0005] A laser cutting head, which is arranged on the Y-direction moving plate of the three-axis motion platform close to one of the drill bit assemblies;

[0006] A protective cover, which is arranged on the Y-direction moving plate of the three-axis motion platform through a screw cylinder.

[0007] Preferably, the cylinder end of the screw cylinder and the laser cutting head are jointly arranged on a mounting seat. The mounting seat is slidably arranged on the Y-direction moving plate and is connected to a driving member. The telescopic rod end of the screw cylinder is connected to the protective cover through a connecting arm.

[0008] Preferably, a guide rail is provided on the Y-direction moving plate. The guide rail is arranged along the Y direction. The mounting seat is slidably arranged on the guide rail, and the laser cutting head is arranged facing the through hole.

[0009] Preferably, the driving member is a telescopic cylinder.

[0010] Preferably, two of the drill bit assemblies are symmetrically arranged on both sides of the through hole along the Z direction, and the other two drill bit assemblies are arranged on both sides of the through hole along the Y direction. The laser cutting head is arranged close to one of the drill bit assemblies arranged along the Y direction.

[0011] In the utility model, a spiral air cylinder is arranged to drive the protection cover to act. When the laser cutting head is not working, the protection cover is automatically covered on the glass sheet of the laser cutting head, protecting the glass sheet of the laser cutting head from being scratched by cutting debris. The whole protection operation can be completely mechanized without manual operation, which not only has high efficiency but also good safety. Description of the Drawings

Detailed Embodiments

[0016] To clearly illustrate the technical features of the present solution, the utility model will be described in detail below through specific embodiments in combination with the drawings.

[0017] In addition, in the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0018] As Figures 1-3As shown in the figure, a laser cutter protector for a laser sawing and milling device is provided on a drilling and milling device. The drilling and milling device includes a frame 1, and a three-axis motion platform 2 is provided on the frame 1. Here, the three-axis motion platform 2 is based on a gantry as a fixed frame, on which a Z-direction plate and a Y-direction plate are provided. Since this structure is a prior art, those skilled in the art all know that the three-axis motion platform 2 is its specific name. The operating sequence of the three-axis motion platform 2 is that the X-axis, Z-axis, and Y-axis have a passing port 4 for the profile to pass through.

[0019] Four drill bit assemblies 5 are provided on the three-axis motion platform 2 of the frame 1. Therefore, the four drill bit assemblies 5 can move relative to the frame 1 in the X direction, lift and lower in the Z direction, and move in the Y direction. In this application, the above-mentioned X direction is the left-right direction in the attached drawing, the Z-direction lift is the up-down direction in the attached drawing, and the Y-direction movement is the front-back direction in the attached drawing. The four drill bit assemblies 5 can drill holes on the four surfaces of the profile simultaneously or sequentially.

[0020] The laser cutter protector includes a laser cutting head 10 and a protective cover 8. The laser cutting head 10 is provided near one of the drill bit assemblies 5 on the Y-direction moving plate 3 of the three-axis motion platform 2. The protective cover 8 is provided on the Y-direction moving plate 3 of the three-axis motion platform 2 through a screw cylinder 7. The screw cylinder 7 can advance and retreat in the Y direction while rotating forward and backward. The screw can rotate the protective cover 8 until its center coincides with the center of the laser cutting head 10, and the Y-direction advance and retreat can cover the protective cover 8 on the laser cutting head 10. In addition, the screw cylinder 7 can achieve two movements simultaneously, which is simpler in structure and more convenient for installation and disassembly compared to other structures where the two movements of feeding first and then rotating or rotating first and then feeding are carried out separately.

[0021] Furthermore, the cylinder end of the screw cylinder 7 and the laser cutting head 10 are jointly provided on a mounting seat 12. The mounting seat 12 is slidably provided on the Y-direction moving plate 3 and is connected to a driving member 6. The telescopic rod end of the screw cylinder 7 is connected to the protective cover 8 through a connecting arm 9. The purpose of the connecting arm 9 is to make the center line of the protective cover 8 coincide with the center line of the laser cutting head 10 after the screw cylinder 7 rotates. In addition, slidingly setting the laser cutting head 10 can adjust the distance between it and the profile.

[0022] Furthermore, the center of the Y-direction moving plate 3 has a passing port 4 for the profile to pass through. The shape of the passing port 4 is square, which is to basically match the cross-sectional shape of the profile. Setting the passing port 4 at the center of the Y-direction moving plate 3 can shorten the position adjustment distance of the drill bit assembly 5 in the Y direction during drilling, and at the same time can reduce the weight of the Y-direction moving plate 3. For the above-mentioned sliding setting of the mounting seat 12 on the Y-direction moving plate 3, specifically, guide rails 11 are provided on the Y-direction moving plate 3. The guide rails 11 are arranged in the Y direction, and the mounting seat 12 is slidably provided on the guide rails 11. The laser cutting head 10 is arranged facing the passing port 4.

[0023] Further, the driving member 6 is a telescopic cylinder, preferably an air cylinder or an electric cylinder. The electric cylinder has a simple structure, is convenient for installation and disassembly, and does not require accessories such as air circuits or oil circuits. The air cylinder is used because of the setting of the above-mentioned spiral air cylinder 7. Here, the air cylinder can share a gas source with the spiral air cylinder 7 and be configured with different air circuits, without the need to separately set up a power device.

[0024] Further, two of the drill bit assemblies 5 are symmetrically arranged up and down on both sides of the through port 4, and the other two drill bit assemblies 5 are arranged front and back on both sides of the through port 4. The laser cutting head 10 is arranged close to the drill bit assembly 5 on the front side of the through port 4. In most cases, the profile mullion is generally placed on its side, and the laser cutting head 10 is generally arranged on the front and back sides of the through port 4, which is also convenient for operators to install and disassemble.

[0025] The above specific implementation manners cannot be used as a limitation on the protection scope of the present invention. For those skilled in the art of this technology, any alternative improvement or transformation made to the implementation manners of the present invention falls within the protection scope of the present invention.

[0026] Those parts not described in detail in the present invention are all well-known technologies to those skilled in the art of this technology.
