[0002] Laser processing of metal parts is a specific application of laser processing technology in the field of metal materials.

[0003] Laser processing offers high precision; even minute displacements or wobbles can lead to processing deviations. By using a clamping device to firmly fix the metal part, it is ensured that the metal part is in a precise position and orientation during processing, allowing the laser beam to accurately act on the predetermined area, thereby guaranteeing the dimensional and shape accuracy of the processed part.

[0004] Existing metal clamping fixtures require the metal part to be unclamped and re-clamped before processing on the other side, resulting in low processing efficiency. Therefore, a clamping fixture for a metal laser processing platform is proposed to solve the above problems. Utility Model Content

[0012] One end of the spring is fixedly connected to the lower outer wall of the plug rod, and the other end of the spring is fixedly connected to the upper inner wall of the connecting arm.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the insertion rod is slidably connected to the upper inner wall of the connecting arm, and the lower side of the insertion rod is engaged in the limiting hole.

[0022] 1. In this utility model, the positioning block is released by moving the insert rod, and the positioning block is moved to the right to separate the through groove from the fixing block. Then the positioning block is rotated. The rotation of the positioning block drives the metal part to rotate through the connecting column, clamping block one and clamping block two. After the adjustment is completed, the positioning block is pushed to the left and fixed in position by the insert rod. The processing surface of the metal part can be adjusted without removing the metal part, which is highly flexible and improves the processing efficiency.

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a clamping fixture for a metal laser processing platform, including a connecting arm 1. The connecting arm 1 serves as a connector and provides support for the sliding of a positioning block 5. A positioning block 5 is slidably connected to the inner wall of the right side of the connecting arm 1. By moving the insert rod 3, the fixing of the positioning block 5 is released, and the positioning block 5 moves to the right, causing the through groove 14 to leave the outer wall of the fixing block 4, thus releasing the limitation on the positioning block 5. Rotating the positioning block 5 can drive the connecting column 6 to rotate. The positioning block 5 has four through grooves 14. The inner wall of the positioning block 5 has limit holes 15. When the insert rod 3 is engaged with the inner wall of the limit hole 15, the position of the positioning block 5 is fixed. When the insert rod 3 leaves the inner wall of the limit hole 15, the fixing of the positioning block 5 is released. A fixing block 4 is fixedly connected to the outer wall of the connecting arm 1. The fixing block 4 is snapped into the through groove 14 to restrict the rotation of the positioning block 5. A guide rod 2 is fixedly connected to the upper outer wall of the connecting arm 1. The guide rod 2 is set to limit the insertion rod 3. A limit component is set on the inner wall of the connecting arm 1. The limit component is used to limit the positioning block 5. A connecting post 6 is fixedly connected to the right end of the positioning block 5. The connecting post 6 plays a connecting role. The connecting post 6 is set to connect the positioning block 5 and the clamping block 10. A clamping block 10 is fixedly connected to the right end of the connecting post 6. The clamping block 10 is set to provide support for the rotation of the screw 7. A clamping block 2 9 is slidably connected to the clamping block 10. The clamping block 2 9 cooperates with the clamping block 10 to clamp the metal part. A positioning component is set on the upper inner wall of the clamping block 10. The positioning component is used to position the clamping block 2 9.

[0032] Reference Figure 1 and Figure 2 The positioning component includes a screw 7, which is used to adjust the position of the slider 12. The screw 7 is rotatably connected to the inner wall of the clamping block 10. The slider 12 is threaded through the screw 7. The slider 12 cooperates with the locking block 8 to fix the clamping block 9. The outer wall of the slider 12 is slidably connected to the inner wall of the clamping block 10. The locking block 8 is elastically connected to the inner wall of the clamping block 9 by a spring 2 11. When the left outer wall of the locking block 8 leaves the inner wall of the slider 12, the limiting of the clamping block 9 can be released. When the left outer wall of the locking block 8 is engaged with the inner wall of the slider 12, the position of the clamping block 9 can be fixed. The outer wall of the locking block 8 is slidably connected to the inner wall of the clamping block 9. The left outer wall of the locking block 8 is engaged with the right inner wall of the slider 12. One end of the spring 2 11 is fixedly connected to the upper inner wall of the clamping block 9, and the other end of the spring 2 11 is fixedly connected to the right outer wall of the locking block 8.

[0033] Reference Figure 1 and Figure 3The limiting component includes a rod 3. The rod 3 is engaged with the inner wall of the limiting hole 15 to fix the position of the positioning block 5. Moving the rod 3 upward stretches the spring 13. Once the rod 3 moves upward away from the inner wall of the limiting hole 15, the fixing of the positioning block 5 can be released. The outer wall of the rod 3 is slidably connected to the upper inner wall of the connecting arm 1. The lower side of the rod 3 is engaged in the limiting hole 15. The lower outer wall of the rod 3 is elastically connected to the upper inner wall of the connecting arm 1 through the spring 13. One end of the spring 13 is fixedly connected to the lower outer wall of the rod 3, and the other end of the spring 13 is fixedly connected to the upper inner wall of the connecting arm 1.

[0034] Working principle: By placing the metal part on clamping block 10, and then rotating screw 7, the rotation of screw 7 drives slider 12 to move downward. The movement of slider 12 drives clamping block 8 and clamping block 2 9 to move downward until clamping block 2 9 cooperates with clamping block 10 to clamp the metal part. After processing, by moving clamping block 8 to release the limit on clamping block 2 9, clamping block 2 9 can be moved upward to release the clamping of the metal part. Place an unprocessed metal part of the same specification on it, and move clamping block 2 9 downward to release clamping block 8 to engage in slider 12, thus realizing the rapid clamping of metal parts of the same specification.

[0035] When it is time to process the other side of the metal part, release the fixing of the positioning block 5 by moving the insert rod 3, move the positioning block 5 to the right, so that the through groove 14 is separated from the fixing block 4, and then rotate the positioning block 5. The rotation of the positioning block 5 drives the metal part to rotate through the connecting column 6, clamping block 10 and clamping block 2 9. After the adjustment is completed, push the positioning block 5 to the left and fix the position by inserting the insert rod 3.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
