Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a floating adjustment clamping assembly for laser cutting. Background Technology

[0002] Laser cutting, with its advantages of high precision and non-contact processing, has been widely used in aerospace, electronics manufacturing, and automotive parts industries. During laser cutting, stable workpiece clamping is crucial for ensuring cutting accuracy and quality. Existing clamping devices use several sets of clamping mechanisms to hold and position the workpiece at multiple edge surfaces, but they lack floating adjustment capabilities. When faced with workpiece positional deviations or irregular shapes, clamping instability can easily occur, affecting cutting quality and equipment safety. This makes it difficult to meet the needs of operators and, to some extent, reduces the practicality of the clamping device. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0004] A floating adjustment clamping assembly for laser cutting includes:

[0005] Workbench;

[0006] At least two sets of adjustment components are fixedly mounted on the worktable;

[0007] The clamping component includes a movable rod movably disposed on the adjusting assembly, a fixed frame disposed at the end of the movable rod, toothed plates slidably inserted into both ends of the fixed frame, and a gear meshing and rotating between the two sets of toothed plates. A mounting plate is fixedly connected to one end of the toothed plate outside the fixed frame, and a clamping part is threadedly inserted into the mounting plate.

[0008] The external force drives the gear to rotate, and the gear drives the two sets of toothed plates to move, controlling the two sets of clamping parts to move in a direction away from or towards each other.

[0009] As an improvement to the above technical solution, the adjustment component includes a mounting base fixedly disposed on the workbench, a mounting groove formed on the mounting base, and a lead screw rotatably inserted into the mounting groove, wherein the lead screw is threadedly connected to the moving rod.

[0010] As an improvement to the above technical solution, a spring is wound around the surface of the lead screw and at the bottom of the moving rod.

[0011] As an improvement to the above technical solution, a motor is also included. The gear is rotatably connected to the fixed frame via a rotating shaft, and the output shaft of the motor is connected to the rotating shaft to drive the rotating shaft and the gear to rotate.

[0012] The beneficial effects of this utility model are:

[0013] The gear meshes with the double-sided toothed plates to achieve synchronous approach or departure of the clamping parts, thereby completing the automatic clamping or releasing operation of the workpiece, improving work efficiency. The gear-toothed plate transmission structure ensures that the movement of the clamping parts on both sides is symmetrical and synchronous, and the clamping force is evenly distributed, avoiding workpiece displacement or damage due to uneven force. The moving rod can float up and down in the adjustment component, driving the clamping parts to float as a whole, so that multiple clamping points can automatically align with the center line of the workpiece. It is suitable for multi-station clamping and irregular curved surface workpieces, effectively preventing cutting deviation. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] A floating adjustment clamping assembly for laser cutting includes:

[0019] Workbench 10;

[0020] At least two sets of adjustment components are fixedly mounted on the worktable 10;

[0021] The clamping member 40 includes a movable rod 30 movably disposed on the adjusting assembly, a fixed frame 41 disposed at the end of the movable rod 30, toothed plates 42 slidably inserted into both ends of the fixed frame 41, and a gear 43 meshing and rotating between the two sets of toothed plates 42. A mounting plate 44 is fixedly connected to one end of the toothed plate 42 located outside the fixed frame 41, and a clamping part 45 is threaded into the mounting plate 44.

[0022] The external force drives the gear 43 to rotate, and the gear 43 drives the two sets of toothed plates 42 to move, controlling the two sets of clamping parts 45 to move in a direction away from or close to each other.

[0023] Specifically, gear 43 simultaneously meshes with the teeth of two sets of toothed plates 42, causing the two sets of toothed plates 42 to move closer or further apart. When the two sets of toothed plates 42 drive the mounting plate 44 closer together, the clamping part 45 moves closer and contacts the workpiece, clamping the workpiece through the mechanical force of gear-toothed plate transmission. Conversely, when the toothed plates 42 move further apart, the clamping part 45 releases the workpiece. The adjusting component allows the moving rod 30 to float up and down, causing the clamping part 40 to float up and down, so that the center point between the multiple sets of clamping parts 40 and the center point of the workpiece are on the same horizontal line. This is suitable for multi-station clamping or irregular curved surface workpieces, avoiding workpiece tilting or cutting offset caused by inconsistent clamping height. When there are differences in workpiece size or shape, the clamping part 45 is threaded into the mounting plate 44, so the position of the clamping head and the clamping force can be adjusted by turning the clamping part 45 to adapt to workpieces of different shapes.

[0024] In one embodiment, the adjustment assembly includes a mounting base 20 fixedly disposed on the worktable 10, a mounting groove 21 formed on the mounting base 20, and a lead screw 22 rotatably inserted into the mounting groove 21. The lead screw 22 is threadedly connected to the moving rod 30. Rotating the lead screw 22 causes the lead screw 22 to drive the moving rod 30 to move up and down, and the moving rod 30 drives the clamping member 40 to move up and down, thereby realizing the vertical floating of the clamping member 40. This ensures that the center point of multiple sets of clamping members 40 is as close as possible to the center point of the workpiece on the same horizontal line, improving the stability of clamping and the accuracy of processing.

[0025] In one embodiment, a spring 23 is wound around the surface of the lead screw 22 and at the bottom of the moving rod 30. During the clamping process, if uneven clamping force or workpiece displacement is encountered, the spring 23 can provide a certain elastic buffer, making the clamping more stable.

[0026] It also includes a motor. The gear 43 is rotatably connected to the fixed frame 41 via a rotating shaft. The output shaft of the motor is connected to the rotating shaft and is used to drive the rotating shaft and the gear 43 to rotate. The motor can drive the gear 43 to rotate, so that the gear 43 drives the two sets of toothed plates to move.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
