It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] See also Figure 1-Figure 5 , a laser cutting machine with a composite workbench disclosed in the utility model, includes a machine table 1, a table 2 for placing a workpiece for processing is provided on the machine table 1, a movable laser head 3 adapted to the table 2 is provided on the machine table 1, generally, the table 2 is arranged below the laser head 3, and the laser head 3 achieves the effect of workpiece cutting by emitting a laser beam in the direction of the table 2.

[0024] The table 2 is detachably provided with a support assembly 4 for supporting a workpiece, and the support assembly 4 is horizontally arranged along the length direction of the table 2. The table 2 is specifically provided with a connection assembly, which includes an annular square frame 21, and the annular square frame 21 is preferably composed of four frames, each of which is provided with a plurality of clamping holes 22, and the two ends of the support assembly 4 are clamped with the corresponding clamping holes 22 on the two oppositely arranged frames.

[0025] As an embodiment of this solution, Figure 2 As shown, the support assembly 4 is a plurality of support racks 41, each of which includes a horizontal bar 411, and a plurality of raised vertical bars 412 are provided on the horizontal bar 411, and the connection between the entire support rack 41 and the table 2 is realized by engaging the two ends of the horizontal bar 411 with the two clamping holes 22. The workpiece is placed against the plurality of vertical bars 412, and a processing gap is formed between each two vertical bars 412, and the cutting operation of the workpiece is completed by the movement of the laser head 3. Preferably, a connecting member is provided on the table 2, and a plurality of clamping slots are provided on the connecting member. A clamping block adapted to the clamping slot is provided on both sides of each support rack 41, and the support rack 41 and the table 2 can be fixedly connected by embedding the clamping block into the clamping slot. On the contrary, the support rack 41 and the table 2 can be separated by pulling the clamping block out of the clamping slot, so as to facilitate the replacement of the support rack 41 damaged during the cutting process. For the support rack 41, the processing gap is fixed, the cost is low, and it is specifically adapted to the processing of workpieces with simple cutting requirements.

[0026] As another embodiment of this solution, Figure 3As shown, the support assembly 4 is a plurality of ejector assemblies 42, each of which includes a base 421, a plurality of metal ejector pins 422 on the base 421, and the connection between the entire ejector assembly 42 and the table 2 is realized by engaging the two ends of the base 421 with the two clamping holes 22. Each metal ejector pin 422 is preferably detachably connected to the base 421, and the position and density of the plurality of metal ejector pins 422 can be adjusted on the base 421, which can adapt to the processing of different workpieces, and can also avoid the overlap of the position to be cut and the support position, resulting in the adhesion of the workpiece and the support assembly 4 after the cutting is completed. In addition, the metal ejector pin 422 is strong and can meet the processing requirements of heavy workpieces. Furthermore, each metal ejector pin 422 is detachably provided with a rubber cap to prevent the metal ejector pin 422 from scratching the surface of the workpiece during the processing.

[0027] In order to stabilize the position of the workpiece during laser cutting, a plurality of clamping assemblies 5 are provided on the table 2. The clamping assemblies 5 are arranged between the laser head 3 and the supporting assembly 4. The clamping assemblies 5 are used to clamp the workpiece to fix the position of the workpiece. The workpiece is specifically fixed between two clamping assemblies 5 to facilitate subsequent laser cutting by the laser head 3. Specifically, each clamping assembly 5 includes a base plate 51, to which a vertically arranged lifting cylinder 52 is connected, and a pressure plate 53 is connected to the output shaft of the lifting cylinder 52. When the lifting cylinder 52 drives the pressure plate 53 to rise, the distance between the pressure plate 53 and the base plate 51 is enlarged, that is, the entire clamping assembly 5 is in an open state, and the workpiece can be placed between the base plate 51 and the pressure plate 53. Subsequently, the lifting cylinder 52 drives the pressure plate 53 to move downward, that is, the pressure plate 53 moves toward the direction of the base plate 51, so that the distance between the pressure plate 53 and the base plate gradually decreases until the pressure plate 53 abuts against the workpiece. At this time, the workpiece is fixed between the pressure plate 53 and the base plate 51. At this time, the entire clamping assembly 5 is in a clamped state, and the workpiece is fixed to facilitate subsequent laser cutting operations.

[0028] In order to adapt to workpieces of various sizes, a plurality of clamping assemblies 5 are connected to a driving assembly 6, and the driving assembly 6 is used to drive each clamping assembly 5 to move horizontally along the length direction of the table 2. That is, the two clamping assemblies 5 move under the drive of the driving assembly 6, and the distance between each other can be adjusted to adapt to workpieces of different sizes. Specifically, the driving assembly 6 includes a linear optical axis slide rail 61 horizontally arranged on the table 2, and each clamping assembly 5 is provided with an axial slider 54 adapted to the linear optical axis slide rail 61, and the axial slider 54 is specifically arranged on the base plate 51. When the linear optical axis slide rail 61 drives the axial slider 54 to move along the length direction of the linear optical axis slide rail 61, the base plate 51 moves along with the movement of the axial slider 54, and the movement of the base plate 51 can drive the pressure plate 53 to move, that is, it can drive the entire clamping assembly 5 to move horizontally, so as to achieve the effect of adjusting the distance between the two clamping assemblies 5. In order to improve the movement stability of the clamping assembly 5, two linear optical axis slide rails 61 are provided, and a plurality of support assemblies 4 are provided between the two linear optical axis slide rails 61. Each clamping assembly 5 is provided with two shaft-type slide blocks 54 adapted to the two linear optical axis slide rails 61.

[0029] Furthermore, in order to improve the working efficiency so that the entire machine 1 can process at least two or more workpieces at the same time, at least four clamping assemblies 5 are provided, and every two clamping assemblies 5 fix one workpiece.

[0030] In order to improve the practicality of the laser cutting machine, this solution lists three working modes of the laser cutting machine, among which the first working mode is: the support rack 41 cooperates with the clamping assembly 5, and the support rack 41 is used to support and position the workpiece while the clamping assembly 5 further stabilizes the position of the workpiece. The second working mode is: the ejector assembly 42 cooperates with the clamping assembly 5, and similarly, the metal ejector 422 is used to support and position the workpiece while the clamping assembly 5 further stabilizes the position of the workpiece. The third working mode is: only the support rack 41 or only the ejector assembly 42 is used to support and position the workpiece, and the clamping assembly 5 is not needed, which is suitable for cutting workpieces with simple cutting requirements.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
