DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 2 , a laser cutting robot for steel plate processing and forming, comprising:

[0022] A workbench 1 is fixedly connected to a mounting frame 2, a telescopic cylinder 3 is mounted on the mounting frame 2, an output end of the telescopic cylinder 3 is fixedly connected to a mounting block 4, and a laser cutting machine 5 is mounted at the bottom of the mounting block 4.

[0023] The protective mechanism includes a protective cover 6, a reset spring 7, an extrusion block 8 and a clamping assembly. The protective cover 6 is slidably connected to the mounting frame 2. A plurality of reset springs 7 are fixedly connected between the top of the protective cover 6 and the mounting frame 2. A through groove 61 is provided on the protective cover 6 to match the clearance of the laser cutting machine 5. Extrusion blocks 8 are connected to both sides of the protective cover 6. A placement slot 9 is provided on the workbench 1. Clamping assemblies are connected to both sides of the placement slot 9. The opposite sides of the two extrusion blocks 8 are connected to the input ends of the two clamping assemblies one by one, and the output ends of the clamping assemblies are located on both sides of the placement slot 9.

[0024] The length of the mounting block 4 is greater than that of the through slot 61 , and a ventilation pipe is connected to the top of the protective cover 6 . The ventilation pipe adopts a multi-bend pipe, which can prevent sparks from directly splashing to the outside of the protective cover 6 through the ventilation pipe while maintaining the ventilation through slot 61 .

[0025] A sealing ring is fixedly connected to the bottom end of the protective cover 6, and the sealing ring is in sealing contact with the upper surface of the workbench 1. The sealing performance of the sealing ring between the protective cover 6 and the workbench 1 can effectively prevent sparks generated by cutting from flying out of the gap between the bottom of the protective cover 6 and the workbench 1.

[0026] The extrusion block 8 is a wedge-shaped block, and a wedge-shaped groove matching with the extrusion block 8 is provided on the workbench 1 .

[0027] The clamping assembly includes a clamping plate 10, a support rod 11 and a return spring 12. The two clamping plates 10 are symmetrically slidably connected in the placement groove 9. The two clamping plates 10 are fixedly connected to the support rod 11 on the opposite sides. The end of the support rod 11 away from the clamping plate 10 passes through the placement groove 9 and rests on the wedge surface of the extrusion block 8. A return spring 12 is fixedly connected between the support rod 11 and the outer side of the placement groove 9. After the extrusion block 8 moves upward, the clamping plate 10 is moved and reset under the elastic force of the return spring 12, which is convenient for subsequent retrieval of the cut steel plate.

[0028] Two ejection assemblies are connected inside the workbench 1, and the ejection assemblies include a connecting frame 13 and an ejection spring 14. The connecting frame 13 is slidably connected inside the workbench 1, and the connecting frame 13 is U-shaped, and is placed in the bottom of the trough body 9 and is connected to an ejection groove 15. One end of the connecting frame 13 extends into the wedge-shaped groove, and the other end extends into the ejection groove 15. An ejection spring 14 is fixedly connected between the middle of the connecting frame 13 and the inside of the workbench 1.

[0029] The operating principle of the utility model is now described as follows:

[0030] When processing the steel plate, the steel plate is placed in the placement slot 9, and the telescopic cylinder 3 is started. The output end of the telescopic cylinder 3 is extended to drive the mounting block 4 and the laser cutting machine 5 to move downward. The laser cutting machine 5 moves downward through the through slot 61 and enters the protective cover 6. The mounting block 4 moves downward to contact the top of the protective cover 6 and drives the protective cover 6 to move downward, and finally the bottom of the protective cover 6 contacts the surface of the workbench 1, forming a relatively sealed working environment, effectively avoiding sparks generated by cutting and splashing into the environment, and improving the safety of the workers.

[0031] During the downward movement of the protective cover 6, the protective cover 6 drives the extrusion block 8 to move downward. The extrusion block 8 moves downward, and its wedge-shaped surface pushes the support rod 11. The support rod 11 overcomes the return spring 12 to push the clamping plate 10 close to the two sides of the steel plate, thereby forming a clamping and fixing effect on the steel plate from both sides of the steel plate through the two clamping plates 10, thereby improving the stability of the steel plate during processing; at the same time, the extrusion block 8 moves downward, and the bottom end pushes the connecting frame 13 to move downward. The connecting frame 13 overcomes the elastic force of the ejection spring 14, and the connecting frame 13 extends into the placement slot 9 and one end is completely retracted into the ejection slot 15. Therefore, after the processing of the steel plate is completed and the telescopic cylinder 3 is restored, under the elastic force of the ejection spring 14, the connecting frame 13 moves upward through the ejection slot 15 to eject the steel plate out of the placement slot 9, which is convenient for the staff to quickly take and place the steel plate, thereby improving the processing efficiency of the steel plate.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
