Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically relating to a workpiece clamping structure for a laser cutting machine. Background Technology

[0002] A laser cutting machine is a machine tool that uses a laser as a cutting tool. It is mainly used for high-precision and high-efficiency cutting of various materials. During the laser cutting process, in order to ensure the stability and accuracy of the workpiece during cutting, a workpiece clamping structure is usually used to fix the workpiece. Existing workpiece clamping structures are widely used in the field of laser cutting machines. Among them, the threaded clamping structure is a common type. The threaded clamping structure mainly relies on the threaded engagement between the threaded rod and the fixed seat to clamp and limit the workpiece. When the workpiece needs to be clamped, the operator needs to manually and repeatedly turn the threaded rod to move the threaded rod downward along the thread direction until its end is in close contact with the workpiece surface, thereby clamping the workpiece on the cutting table. After the workpiece is cut, if the workpiece needs to be removed, the operator needs to rotate the threaded rod counterclockwise to move the threaded rod upward and release the limitation on the workpiece before the workpiece can be taken out from the cutting table.

[0003] In actual operation, the existing workpiece clamping structure requires repeated tightening of the threaded rod to clamp and release the workpiece. This not only increases the workload of the operator but also consumes a lot of time. Especially in production scenarios involving the cutting of large quantities of workpieces, this operation method significantly reduces production efficiency and increases production costs. At the same time, the clamping component is usually always above the workpiece, which can cause some obstruction to the operator during workpiece loading and unloading. When placing the workpiece, the operator needs to carefully place it under the threaded rod to avoid collision with it. Similarly, when removing the workpiece, it is necessary to go around the threaded rod to remove it smoothly. This obstruction not only reduces the convenience of workpiece loading and unloading but also increases the risk of workpiece damage during loading and unloading. Therefore, this utility model proposes a workpiece clamping structure for a laser cutting machine. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Example

[0023] Please see Figures 1 to 3 This is an embodiment of the present invention, which provides a technical solution: a workpiece clamping structure for a laser cutting machine, comprising...

[0024] Two bases 1 are slidably installed on the top of the laser cutting table 7; a rotating cylinder 2 is rotatably installed on the top of the base 1; an adjustable support plate 5 is set on the side of the rotating cylinder 2; and a clamping component 6 is installed at the end of the adjustable support plate 5.

[0025] The adjustable support plate 5 includes a base plate 51 welded and fixed to the surface of the rotating cylinder seat 2 and a top plate 52 movably installed on the top surface of the base plate 51;

[0026] The clamping assembly 6 includes a movable rod 61 that runs vertically through the top plate 52, a clamping plate 63 installed on the bottom surface of the movable rod 61, an anti-slip pad 64 that is glued to the bottom surface of the clamping plate 63 and presses against the workpiece 8, and a spring 62 that is sleeved on the surface of the movable rod 61 and located between the top plate 52 and the clamping plate 63. The top of the movable rod 61 is also fixed with a lifting block 65 relative to the top of the top plate 52. The design of the lifting block 65 makes it convenient for subsequent operators to lift the movable rod 61.

[0027] In this embodiment, preferably, the top surface of the base 1 is fixed with a shaft 3, and the rotating cylinder seat 2 is rotatably sleeved on the surface of the shaft 3, so that the rotating cylinder seat 2 can rotate smoothly.

[0028] In this embodiment, preferably, a T-shaped base block 11 is welded and fixed to the bottom surface of the base 1, and a T-shaped groove 71 corresponding to the T-shaped base block 11 is opened on the top surface of the laser cutting machine cutting table 7. The T-shaped base block 11 is slidably located in the T-shaped groove 71, so that the base 1 can slide on the top of the laser cutting machine cutting table 7 to adjust its position and meet the clamping and limiting of the workpiece 8 at different positions.

[0029] In this embodiment, preferably, a screw 53 is welded and fixed to the top surface of the base plate 51, and a strip-shaped slide 54 corresponding to the screw 53 is opened through the surface of the top plate 52. The top end of the screw 53 passes through the strip-shaped slide 54 to the top of the top plate 52, and a fastening ring 55 is threadedly fitted on the top surface of the screw 53 relative to the top of the top plate 52. The fastening ring 55 presses and fixes the top plate 52, realizing the stable fixation of the top plate 52 during daily use. When it is necessary to adjust the length of the adjustable support plate 5 laterally, simply rotate the fastening ring 55 counterclockwise to loosen it, release the fixation of the top plate 52, and then move the top plate 52 laterally to change the position of the top plate 52. After adjusting to the appropriate position, rotate the fastening ring 55 clockwise again to tighten it, thus completing the re-fixation of the position of the top plate 52.

[0030] In this embodiment, preferably, the fastening ring 55 is threadedly connected to the screw 53.

[0031] In this embodiment, preferably, the surface of the top plate 52 is also provided with a circular rod hole through which the movable rod 61 passes.

[0032] In this embodiment, preferably, the bottom end of the spring 62 abuts against the top surface of the clamping plate 63, and the top end of the spring 62 abuts against the bottom surface of the top plate 52.

[0033] In this embodiment, preferably, the bottom surface of the anti-slip pad 64 is provided with multiple strip-shaped anti-slip grooves.

[0034] In summary, in actual use, when it is necessary to place workpiece 8 on top of the laser cutting machine cutting table 7, first lift the movable rod 61, then rotate the rotating cylinder seat 2 on top of the base 1, so that the clamping component 6 and the adjustable support plate 5 can be directly rotated to the outside of the T-shaped slide 71, that is, close to the side of the laser cutting machine cutting table 7. This will remove the obstruction of the clamping component 6 and the adjustable support plate 5 on the placement of workpiece 8, making it easier for the operator to place workpiece 8 on the laser cutting machine cutting table 7 more quickly and easily. After placing workpiece 8, lift the movable rod 61 again, and rotate the clamping component 6 and the adjustable support plate 5 to the outside of the T-shaped slide 71, that is, close to the side of the laser cutting machine cutting table 7. When the support plate 5 rotates back to the top of the workpiece 8, the movable rod 61 is released, causing the spring 62 to push the clamping plate 63 down, so that the anti-slip pad 64 can be pressed tightly against the top surface of the workpiece 8. This quickly achieves the clamping and limiting of the workpiece 8, ensuring the stability of the workpiece 8 during the subsequent cutting process. When the workpiece 8 needs to be removed after cutting, simply lift the movable rod 61 and then rotate the rotating cylinder seat 2, so that the clamping component 6 and the adjustable support plate 5 can be rotated and moved directly from above the workpiece 8. This quickly releases the limiting of the workpiece 8 and removes the obstruction to the workpiece 8, allowing the workpiece 8 to be removed quickly.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
