Description

Technical Field

[0001] This utility model belongs to the field of laser cutting technology, specifically relating to a laser cutting positioning platform. Background Technology

[0002] The laser cutting positioning platform is the core unit in laser cutting equipment for achieving precise workpiece positioning. Through the coordinated work of mechanical structure, drive system and detection feedback device, it limits, fixes and adjusts the position of the workpiece, ensuring the relative position accuracy of the workpiece and the laser beam during cutting, and ensuring accurate cutting contour dimensions and surface flatness.

[0003] However, in laser cutting operations, large sheet metal parts are often processed on the rack structure of the positioning platform. Although the small waste generated during cutting can fall into the waste hopper below through the gap, when it is necessary to clean up the waste, the machine must be stopped and the rack assembly must be removed. This operation seriously interrupts the continuity of processing. Frequent disassembly and assembly not only reduces the utilization rate of the equipment, but may also lead to rack deformation and a decrease in positioning accuracy, further affecting the cutting quality of subsequent sheet metal parts, becoming a key bottleneck restricting processing efficiency.

[0004] To address the aforementioned issues, this application proposes a laser cutting positioning platform. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a laser cutting positioning platform, which has the characteristic of improving the processing efficiency of laser cutting operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting positioning platform, including a support frame, a rack frame fixedly connected to the upper surface of the support frame, a controller provided on the left side of the support frame, a push frame slidably connected to the inner wall of the support frame, sliding groove frames and brake motors provided on both sides of the support frame, a sliding block slidably connected inside each sliding groove frame, the upper and bottom surfaces of each sliding block contacting the inner wall of the support frame, the sides of two sliding blocks close to each other being fixedly connected to the two sides of the push frame, a threaded rod rotatably connected to the inner wall of each sliding groove frame, the inner wall of each sliding block being threadedly connected to the outer surface of the threaded rod, and the power output end of each brake motor being fixedly connected to the end of the threaded rod close to the push frame.

[0007] As a preferred embodiment of this utility model, the bottom surface of the support frame is fixedly connected to two sets of connecting columns, and the bottom end of each connecting column is fixedly connected to a support base.

[0008] As a preferred embodiment of this utility model, the support frame has an opening and closing door that is movably hinged to the front, and the opening and closing door has a handle that is fixedly connected to the front.

[0009] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the right side of the controller, and the right side of the connecting plate is fixedly connected to the left side of the support frame.

[0010] As a preferred technical solution of this utility model, each of the sliding groove frames has a reinforcing plate fixedly connected to its upper and bottom surfaces, and the two sets of reinforcing plates are respectively fixedly connected to the two sides of the support frame on their respective sides.

[0011] As a preferred embodiment of this utility model, the inner wall of the support frame is fixedly connected with two reinforcing plates, and the upper surface of each reinforcing plate is in contact with the bottom surface of the rack frame.

[0012] As a preferred embodiment of this utility model, each of the two brake motors is fixedly connected to a connecting seat on one side that is close to each other, and the front of each connecting seat is fixedly connected to the back of the support frame.

[0013] As a preferred embodiment of this utility model, a protective plate is fixedly connected to the front of the pusher, and the protective plate is made of wear-resistant cast iron.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a support frame and a rack frame in cooperation, it not only provides a stable bearing platform for laser cutting of sheet metal, but also allows cutting waste to fall into the support frame through the gap of the rack frame. When it is necessary to clean up the waste, the controller controls the brake motor to rotate forward or reverse, driving the threaded rod to rotate in the sliding groove frame. At the same time, the rotation of the threaded rod drives the sliding block to slide between the sliding groove frame and the inner wall of the support frame, thereby driving the pusher to move horizontally inside the support frame. Through the reciprocating sliding of the pusher, the waste in the support frame can be directly pushed out to the outside without disassembling the rack frame. This design solves the pain point of having to stop the machine to disassemble and clean up the waste, significantly improves the continuity of laser cutting operations, greatly shortens the non-processing time of the equipment, and thus effectively improves processing efficiency.

Example

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a laser cutting positioning platform, including a support frame 1, a rack frame 11 fixedly connected to the upper surface of the support frame 1, a controller 3 provided on the left side of the support frame 1, a push frame 13 slidably connected to the inner wall of the support frame 1, sliding groove frames 4 and brake motors 6 provided on both sides of the support frame 1, a sliding block 15 slidably connected inside each sliding groove frame 4, the upper surface and bottom surface of each sliding block 15 contacting the inner wall of the support frame 1, the sides of two sliding blocks 15 close to each other being fixedly connected to the two sides of the push frame 13 respectively, a threaded rod 17 rotatably connected to the inner wall of each sliding groove frame 4, the inner wall of each sliding block 15 being threadedly connected to the outer surface of the threaded rod 17, and the power output end of each brake motor 6 being fixedly connected to the end of the threaded rod 17 close to the push frame 13;

[0023] In this embodiment, the rack frame 11 is fixedly connected to the support frame 1, and each rack plate is fixed to the frame by bolts and other connecting parts. This structural design not only ensures the stable connection between the rack frame 11 and the support frame 1, but also facilitates the disassembly and maintenance of individual rack plates, and provides a reliable channel for waste materials to fall into the support frame 1 through the gaps between the racks.

[0024] Specifically, two sets of connecting columns 9 are fixedly connected to the bottom surface of the support frame 1. Each connecting column 9 is fixedly connected to a support seat 7 at its bottom end. In this embodiment, the support seat 7 is fixed to the support frame 1 through the connecting columns 9, and the support seat 7 is used to ensure that the support frame 1 is placed stably.

[0025] Specifically, the support frame 1 has an opening and closing door 8 that is movably hinged to the front, and a handle 10 is fixedly connected to the front of the opening and closing door 8. In this embodiment, the support frame 1 can be opened or closed through the opening and closing door 8, and the opening and closing door 8 can be easily opened or closed using the handle 10.

[0026] Specifically, a connecting plate 2 is fixedly connected to the right side of the controller 3. The right side of the connecting plate 2 is fixedly connected to the left side of the support frame 1. In this embodiment, the controller 3 can be fixed by the connecting plate 2. The controller 3 is a programmable logic controller (PLC), which is a digital computing and operating electronic system designed for industrial automation control scenarios. It stores instructions through a programmable memory and performs logical operations, sequential control, timing, counting and arithmetic operations to control various machines or production processes.

[0027] Specifically, each sliding groove frame 4 has a reinforcing plate 5 fixedly connected to its upper and lower surfaces. The two sets of reinforcing plates 5 are fixedly connected to the two sides of the support frame 1 on their respective sides. In this embodiment, the reinforcing plates 5 can reinforce the sliding groove frame 4 to the support frame 1, thereby improving the stability of the sliding groove frame 4.

[0028] Specifically, the inner wall of the support frame 1 is fixedly connected with two reinforcing plates 12. The upper surface of each reinforcing plate 12 is in contact with the bottom surface of the rack frame 11. In this embodiment, the reinforcing plates 12 can support the rack frame 11, thereby improving the stability of the rack frame 11.

[0029] Specifically, each of the two brake motors 6 has a connecting seat 16 fixedly connected to one side of each other. The front of each connecting seat 16 is fixedly connected to the back of the support frame 1. In this embodiment, the brake motor 6 can be fixed by the connecting seat 16. At the same time, the brake motor 6 is a motor that integrates an electromagnetic braking device. It achieves rapid braking and locking of the motor shaft through electromagnetic force or mechanical force. It is often used in scenarios that require precise stopping, prevention of slippage, or maintenance of position.

[0030] Specifically, a protective plate 14 is fixedly connected to the front of the pusher 13. The protective plate 14 is made of wear-resistant cast iron. In this embodiment, the protective plate 14 can protect the contact surface between the pusher 13 and the waste material, thereby improving the service life of the pusher 13.

[0031] The working principle and usage process of this utility model are as follows: First, the support frame 1 is fixed to the ground via the connecting column 9 and the support base 7 to ensure the equipment is level and stable. Then, the controller 3 is installed via the connecting plate 2 and the wiring of the brake motor 6 is connected. The PLC program is debugged to match the waste cleaning logic. Next, the sheet metal parts are placed on the rack frame 11 and fixed. The laser cutting equipment is started to process the workpiece. The waste generated during cutting falls into the support frame 1 through the gap in the rack frame 11. When waste needs to be cleaned, the opening and closing door 8 is opened, and the controller 3 sends a command to control the brake motor 6 to rotate forward, driving the threaded rod 17... The sliding groove frame 4 rotates, causing the sliding block 15, which is threadedly connected to the threaded rod 17, to slide horizontally within the sliding groove frame 4. This drives the pusher 13 to slide on the inner wall of the support frame 1. The protective plate 14 at its front end pushes the waste material from the support frame 1 to the external collection device. After cleaning is completed, the opening and closing door 8 is closed, and the controller 3 controls the brake motor 6 to reverse, driving the pusher 13 and the protective plate 14 back to the initial position. At this time, the built-in brake of the brake motor 6 automatically locks, preventing the threaded rod 17 and the pusher 13 from shifting. The entire process does not require disassembling the rack frame 11, effectively improving the continuity and processing efficiency of laser cutting operations.
