Description

Technical Field

[0001] This utility model relates to the field of profile cutting and clamping technology, specifically to a profile clamping device for a laser cutting machine. Background Technology

[0002] Profiles are objects with specific geometric shapes made of iron or steel and other materials with certain strength and toughness through processes such as rolling, extrusion, and casting. In profile production, laser cutting machines can be used to cut profiles to the appropriate lengths according to actual needs. A search revealed an existing technology (publication number: CN202122959056.8) for a clamping device for profile cutting. The technology describes that "when profiles need to be cut, the lower clamping assembly clamps the profile vertically, and the upper clamping assembly clamps the profile horizontally. The profile drives the lower clamping assembly, the upper clamping assembly, and the sliding plate to move along the extrusion direction of the profile on the frame. The sliding plate drives the cutting equipment to move along the extrusion direction of the profile on the frame, and the cutting equipment simultaneously cuts the profile. This clamping device reduces the possibility of relative displacement between the profile and the cutting equipment during profile cutting, improving the cutting quality of the profile." However, in the existing technology, excessive clamping force during the clamping process of the upper and lower clamping assemblies can easily lead to localized deformation of the profile surface. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a profile clamping device for laser cutting machines is provided to solve the problem that excessive clamping force during the clamping process of the upper and lower clamping components in existing technologies can easily lead to local deformation of the profile surface.

[0004] To achieve the above objectives, a profile clamping device for a laser cutting machine is provided, comprising: a laser cutting table, wherein an electric slide is mounted on the upper groove surface of the laser cutting table. The upper end of the electric slide is connected to a roller frame, and rollers are axially connected to the inner side of the roller frame. Two sets of vacuum suction plates are provided at the front end of the rollers. The rear end face of the vacuum suction plates is provided with suction holes. The front end of the vacuum suction plates is connected to a vacuum pump through a vacuum tube. The front end of the vacuum suction plates is connected to a trapezoidal lead screw through a nut block. The lower end of the trapezoidal lead screw is fixed to the laser cutting table surface through a bearing seat. A fixing frame is welded to the laser cutting table surface. The fixing frame is connected to a roller frame through an adjusting stud. A pressure roller is installed on the inner side of the roller frame.

[0005] Furthermore, a control panel is provided on the front surface of the laser cutting stage, and a vacuum pump is distributed on the right side of the control panel.

[0006] Furthermore, an anti-slip pad is adhered to the rear surface of the vacuum suction plate; and the grooves on the surface of the anti-slip pad are distributed correspondingly to the adsorption holes, and a limit groove block is welded to the front surface of the vacuum suction plate.

[0007] Furthermore, a limiting post extends through the inner side of the limiting groove block, and the lower end of the limiting post is welded to the surface of the laser cutting table. A trapezoidal lead screw is provided between the spacing of the limiting posts.

[0008] Furthermore, the vacuum tube is connected to the adsorption hole through the inner cavity of the vacuum suction plate, and a pressure sensor is installed on the side end of the vacuum suction plate.

[0009] Furthermore, an adjusting rod head is welded to the upper end of the trapezoidal lead screw, and the pressure rollers are distributed at the left and right sides of the vacuum suction plate.

[0010] Furthermore, the I-beam profile is clamped at the distance between the roller and the vacuum suction plate; and the pressure roller rolls and adheres to the upper surface of the I-beam profile.

[0011] The beneficial effects of this utility model are as follows: The profile clamping device for laser cutting machines utilizes an electric slide table to drive the rollers to push the profile forward, so that the front end face of the profile is in contact with the surface of the vacuum suction plate. The clamping device is located between the rollers and the vacuum suction plate. By using a vacuum pump to remove the air from the vacuum suction plate cavity, a negative pressure is formed at the suction holes of the vacuum suction plate to tightly adhere to the front surface of the profile. This facilitates stable and safe clamping of the profile during laser cutting, preventing the profile from shifting during laser cutting, effectively reducing deformation at the clamping end face of the profile, and improving the production quality of profile cutting. By adjusting the adjusting stud to press down on the upper end face of the profile under the holding roller, it ensures that longer profiles are fully in contact with the processing table, guaranteeing the flatness of the profile cutting end.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 4 As shown, this utility model provides a profile clamping device for a laser cutting machine, including: a laser cutting table 1, and an electric slide 14 installed on the upper groove surface of the laser cutting table 1. The upper end of the electric slide table 14 is connected to a roller frame 21. A roller 2 is axially connected to the inner side of the roller frame 21. Two sets of vacuum suction plates 3 are set at the front end of the roller 2. The rear end face of the vacuum suction plate 3 is provided with an adsorption hole 36. The front end of the vacuum suction plate 3 is connected to a vacuum pump 32 through a vacuum tube 31. The front end of the vacuum suction plate 3 is connected to a trapezoidal lead screw 4 through a nut block 41. The lower end of the trapezoidal lead screw 4 is fixed to the surface of the laser cutting table 1 through a bearing seat. A fixing frame 11 is welded to the upper surface of the laser cutting table 1. The fixing frame 11 is connected to a roller frame 51 through an adjusting stud 52. A pressure roller 5 is installed on the inner side of the roller frame 51.

[0019] First, place the profile to be cut on the laser cutting table 1. Rotate the trapezoidal screw 4 to adjust the height of the vacuum suction plate 3 so that the vacuum suction plate 3 is positioned at the front end of the profile. Then, adjust the height of the pressure roller 5 so that the pressure roller 5 presses down on the upper surface of the profile. Control the electric slide table 14 to drive the roller frame 21 to move forward, so that the roller 2 pushes the profile forward and clamps the profile between the vacuum suction plate 3 and the roller 2. When the pressure sensor 35 senses a certain pressure value, the roller 2 stops moving and the vacuum pump 32 is started so that the suction holes 36 of the vacuum suction plate 3 adsorb the front surface of the profile under negative pressure, thereby preventing the profile from shifting during the cutting process. The adsorption clamping structure effectively reduces the deformation at the clamping end face of the profile and improves the production quality of profile cutting.

[0020] In this embodiment, a control panel 12 is provided on the front surface of the laser cutting stage 1, and a vacuum pump 32 is distributed on the right side of the control panel 12. An anti-slip pad 33 is adhered to the rear surface of the vacuum suction plate 3; and the grooves on the surface of the anti-slip pad 33 correspond to the adsorption holes 36. A limiting groove block 34 is welded to the front surface of the vacuum suction plate 3. A limiting post 13 passes through the inner side of the limiting groove block 34, and the lower end of the limiting post 13 is welded to the upper surface of the laser cutting stage 1. Trapezoidal lead screws 4 are provided between the spacing of the limiting posts 13.

[0021] In a preferred embodiment, the control panel 12 facilitates receiving signals from the pressure sensor 35 and controlling the operation of the electric slide table 14. The vacuum suction plate 3 is in close contact with the surface of the profile via the anti-slip pad 33, and the front side of the vacuum suction plate 3 is effectively supported by the limiting groove block 34 and the limiting post 13 of the laser cutting table 1, so that the vacuum suction plate 3 can firmly adsorb and clamp the profile.

[0022] In this embodiment, the vacuum tube 31 is connected to the adsorption hole 36 through the inner cavity of the vacuum suction plate 3, and a pressure sensor 35 is installed on the side of the vacuum suction plate 3. An adjusting rod head 42 is welded to the upper end of the trapezoidal lead screw 4, and the pressure rollers 5 are distributed at the left and right sides of the vacuum suction plate 3. The I-beam profile is clamped at the distance between the roller 2 and the vacuum suction plate 3; and the pressure rollers 5 roll and adhere to the upper surface of the I-beam profile.

[0023] As a preferred implementation, the pressure sensor 35 monitors the clamping force of the roller 2 and the vacuum suction plate 3 to prevent excessive forward thrust of the roller 2 from causing deformation of the profile. The trapezoidal lead screw 4 has self-locking properties. By rotating the adjusting rod head 42, the nut block 41 converts the rotational motion into linear motion, driving the vacuum suction plate 3 to move up and down, adjusting the adsorption position of the vacuum suction plate 3, and ensuring that the vacuum suction plate 3 can fully adsorb the profile surface, making it easier for the vacuum suction plate 3 to more firmly and safely adsorb and clamp the profile during laser cutting.

[0024] This utility model of a profile clamping device for laser cutting machines effectively solves the problem in the prior art where excessive clamping force during the clamping process of the upper and lower clamping components can easily lead to local deformation of the profile surface. It facilitates stable and safe adsorption and clamping of the profile during laser cutting, prevents the profile from shifting during laser cutting, effectively reduces deformation at the clamping end face of the profile, improves the production quality of profile cutting, ensures that longer profiles are fully attached to the processing table, and guarantees the flatness of the profile cutting end. It is suitable for profile clamping devices for laser cutting machines.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
